Description
BACKGROUND
[0001] 1. Technical Field
[0002] The present disclosure relates to a polishing device.
[0003] 2. Description of Related Art
[0004] Workpieces need to be polished by different polishing tools
having different roughness in different steps of a polishing
process. However, polishing devices usually have only one polishing
tool to polish the workpieces. Therefore, when a first polishing
tool polishes the workpieces, the polishing process must be
temporarily stopped until the first polishing tool has been
replaced with a second polishing tool which has a different
roughness. This is very inconvenient, and the work efficiency is
reduced.
[0005] Therefore, it is desirable to provide a polishing device
that can overcome the above-mentioned limitations.

are not limited to this embodiment.
[0011] The bracket 10 includes a base 100 and two rectangular
fixing frames 101. The base 100 defines a cleaning tank 104 filled
with water for cleaning the workpieces 22, and includes a
rectangular platform 102, five pairs of fixing plates 108, and two
sidewalls 100a perpendicularly extending from the two long edges of
the platform 102. The platform 102 defines four openings 106 along
the length, communicating with the cleaning tank 104. The five
pairs of fixing plates 108 are positioned along the length of the
platform 102. Each pair of fixing plates 108 are respectively
positioned on two long edges of the platform 102, and are aligned
with each other. Each fixing plate 108 defines a mounting hole 110.
Each opening 106 is positioned between two adjacent pairs of fixing
plates 108.
[0012] The two fixing frames 101 are fixed on the two sidewalls
100a respectively. Each fixing frame 101 includes a mounting plate
103 parallel to the platform 102, a first supporting plate 105a,
and a second supporting plate 105b. The first supporting plate 105a
and the second supporting plate 105b perpendicularly extend from
the two short edges of the mounting plate 103.
[0013] Each loading device 20 includes a loading plate 200 and a
driving element 201. The loading plate 200 includes a rectangular
first main body 203 and a first shaft 204 positioned on an edge of
the first main body 203. The first main body 203 defines a blind
fixing groove 202 for receiving and fixing the workpiece 22. The
two ends of the first shaft 204 are inserted into the two mounting
holes 110 of the two opposite fixing plates 108 to rotatably
connect the first main body 203 to the base 100. The driving
element 201 is connected to one end of the first shaft 204, and is
used for driving the loading plate 203 to rotate around the first
shaft 204.
[0014] The horizontal driving device 30 includes a strip-shaped
stator 300 and a motor 302 slidably positioned on the stator 300.
One end of the stator 300 is fixed between the two first supporting
plates 105a, and the other end of the stator 300 is fixed to the
two second supporting plates 105b. The stator 300 is aligned with
the platform 102, and extends parallel along the length of the
platform 102. The motor 302 is adjacent to the loading plate 102
with respect to the stator 300. In this embodiment, the horizontal
driving device 30 is a linear-motor.
[0015] A vertical driving device 40 is connected to the horizontal
driving device 30, and includes a vertical motor 400 and two
opposite rotating plates 401. The vertical motor 400 includes a
tube-shaped second main body 402 and a second shaft 404 extending
through the second main body 402. The two opposite ends of the
second shaft 404 extend outwards from the second main body 402. The
second main body 402 is connected to the motor 302, and the axial
direction of the second shaft 404 is perpendicular to the extending
direction of the stator 300. An outer sidewall of the second shaft
404 has a protrusion 406 along the axial direction. Each rotating
plate 401 includes a rectangular third main body 403, a ring 405,
and a block 407. The ring 405 perpendicularly extends from a
surface of the rotating plate 401 facing the other rotating plate
401. An inner surface of each ring 405 defines a receiving groove
409 along the axial direction thereof. The two rings 405 cover two
ends of the second shaft 404, and the protrusion 406 is received in
the two receiving grooves 409. Thus, the two rotating plates 401
are symmetrically with each other about the vertical motor 400, and
are able to be rotated by the vertical motor 400 to move toward or
away from the loading plate 102. The block 407 extends from one
corner of the third main body 403, and defines a pinhole 411.
[0016] The supporting device 50 is rotatably positioned between the
two blocks 407, and includes a circular first clamping plate 500
and a circular second clamping plate 501. The first clamping plate
500 defines a through hole 502 in the center thereof. A surface of
the first clamping plate 500 facing the second clamping plate 501
defines four first mounting grooves 504 around the through hole
502. The four first mounting grooves 504 are uniformly positioned
on a circle taking the through hole 502 as a center point. A
surface of the second clamping plate 501 facing the first clamping
plate 500 defines four second mounting grooves 505 aligned with the
four first mounting groves 504. A connecting shaft 503 is aligned
with the through hole 502 and extends outwards from the center of a
surface of a second clamping plate 501 opposite to the first
clamping plate 500.
[0017] Each first driving device 60 includes a fourth main body 600
and a third shaft 602 rotatably positioned on one end of the fourth
main body 600. The fourth main body 600 drives the third shaft 602
to rotate. Each fourth main body 600 is fixedly received in the
corresponding first mounting groove 504.
[0018] Each polishing tool 70 can be driven by the corresponding
first driving device 60 to rotate, and includes a first end surface
70a facing the second clamping plate 501, a second end surface 70b
opposite to the first end surface 70a, and a circumferential
sidewall 700 connected between the first end surface 70a and the
second end surface 70b. A fourth shaft 702 extends from the center
of the first end surface 70a along the rotating axial direction of
the polishing tool 70. The fourth shaft 702 is rotatably received
in the corresponding second mounting groove 505. The second end
surface 70b defines a receiving hole 704 at the center thereof. The
third shaft 602 is fixedly received in the corresponding receiving
hole 704. The circumferential sidewall 700 polishes the workpiece
700. The roughness of the circumferential sidewalls 700 of the four
polishing tools 70 is different.
[0019] The second driving device 80 includes a fifth main body 800
and a fifth shaft 802 rotatably positioned on one end surface of
the fifth main body 800. The fifth main body 800 drives the fifth
shaft 802 to rotate. The fifth shaft 802 fixedly passes through the
pinhole 411 adjacent to the first clamping plate 500 and the
through hole 502 of the first clamping plate 500. The connecting
shaft 503 is rotatably received in the pinhole 411 adjacent to the
second clamping shaft 500.
[0020] The four nozzles 90 spray polishing liquid at the workpieces
22. Two nozzles 90 are fixed on one of the two mounting plates 103
aligned with two of the corresponding openings 106 respectively,
and the other two nozzles 90 are fixed on the other one of the two
mounting plates 103 aligned with the other two corresponding
openings 106 respectively.
[0021] In use, first, the three fixing grooves 202 are upwardly
facing. Each of the three workpieces 22 is fixed in a corresponding
fixing groove 202, and the plane surface 22a faces the stator 300.
The vertical motor 400 drives the rotating plates 401 to rotate,
and thus the supporting device 50 moves towards the base 100. The
second driving device 80 drives the supporting device 50 to rotate
until that a particular polishing tool 70 faces one workpiece 22.
The vertical motor 400 drives the particular polishing tool 70 to
contact with the workpiece 22. The four nozzles 90 spray the
polishing liquid at the four workpieces 22. One first driving
device 60 drives the particular polishing tool 70 to rotate to
polish the workpiece 22. Then, the horizontal driving device 30
drives the particular polishing tool 70 to move along the stator
300, and thus to polish the plane surfaces 22a of the other three
workpieces 22. After a predetermined time interval, the second
driving device 80 rotates the supporting device 50 to allow another
polishing tool 70 to polish the plane surfaces 22a of the four
workpieces 22. After the polishing process is finished, the driving
element 201 drives the first main body 203 to rotate to be received
in the cleaning tank 104, and the polished workpiece can be washed.
In this way, different polishing tools 70 can be used to polish the
same workpiece conveniently, and the work efficiency is
improved.
[0022] It will be understood that the above particular embodiments
and methods are shown and described by way of illustration only.
The principles and the features of the present disclosure may be
employed in various and numerous embodiments thereof without
departing from the scope of the disclosure as claimed. The
above-described embodiments illustrate the scope of the disclosure
but do not restrict the scope of the disclosure.
