Technical Field

[0001] The present application relates to the field of mechanical processing, and in particular to a polishing machine. Background Art

[0002] In the field of mechanical processing, in order to improve the flatness of the workpiece, a polishing machine is needed to polish the workpiece. When the polishing machine currently on the market polishes the workpiece, the workpiece is always fixed on the fixture, and the relative position of the workpiece and the polishing disc remains unchanged, resulting in the polishing disc not being able to polish the workpiece evenly, and the flatness of the workpiece after polishing is not high, and the surface quality is poor. Utility Model Content

[0003] The purpose of the present application is to provide a polishing machine. When the polishing disc polishes the workpiece, the fixing part can drive the workpiece to move, so that the polishing disc can polish the workpiece more evenly, the workpiece has higher flatness and better surface quality.

[0004] The present application provides a polishing machine, comprising a base, a polishing disc and a fixing mechanism, wherein the polishing disc and the fixing mechanism are mounted on the base. The fixing mechanism is provided with a fixing part, and the polishing disc and the fixing part are arranged at intervals along the height direction of the polishing machine. The fixing part is used to fix a workpiece to be polished, and the polishing disc is used to polish the workpiece.

[0005] The fixing part can drive the workpiece to move along a first direction, and the first direction is parallel to the surface of the polishing disc toward the workpiece.

[0006] In the polishing machine provided in the embodiment of the present application, when the polishing disc is polishing the workpiece, the firmware part can drive the workpiece to move along the first direction, so that the polishing disc will not always polish the same position of the workpiece, and the workpiece can be polished evenly by the polishing disc, thereby increasing the flatness of the workpiece and improving the surface quality.

[0007] In some embodiments, the fastener portion includes a first clamp and a second clamp, and along a first direction, the first clamp and the second clamp are spaced apart from each other, and the first clamp and the second clamp can move away from or toward each other, and the first clamp and the second clamp can move synchronously and in the same direction along the first direction.

[0008] The workpiece is located between the first clamp and the second clamp. When the first clamp and the second clamp are close to each other, the workpiece is fixed. When the first clamp and the second clamp are away from each other, the workpiece is released. When the first clamp and the second clamp move synchronously in the same direction, the first clamp and the second clamp drive the workpiece to move. By setting the movable first clamp and the second clamp to fix the workpiece and move the workpiece, the workpiece can be fixed and moved without setting a more complicated mechanism, and the structure is simple and the cost is relatively low.

[0009] In some embodiments, the fastener mechanism further comprises a first side plate and a second side plate, wherein the first side plate and the second side plate are mounted on the base. Along the first direction, the first side plate and the second side plate are located on both sides of the base. The first clamp is connected to the first side plate, and the second clamp is connected to the second side plate.

[0010] The first side plate and the second side plate can move synchronously and in the same direction along the first direction, so as to drive the first clamping jaw and the second clamping jaw to move synchronously and in the same direction along the first direction.

[0011] In some embodiments, the fastener mechanism further comprises a linkage plate, one end of which is fixedly connected to the first side plate, and the other end of which is fixedly connected to the second side plate. By arranging the linkage plate to connect the first side plate and the second side plate, the first side plate and the second side plate can move synchronously and in the same direction, so that the first clamping jaw and the second clamping jaw can move synchronously and in the same direction, and the relative position of the first clamping jaw and the second clamping jaw will not change, thereby preventing the workpiece from falling off.

[0012] In some embodiments, the fastener mechanism further includes a first driving member, which is mounted on the base. The first driving member includes a first driving end, which is connected to the first side plate or the second side plate, and the first driving end drives the first side plate or the second side plate to move, so that the first side plate, the linkage plate and the second side plate move, thereby driving the first clamping jaw and the second clamping jaw to move.

[0013] By arranging the first driving member to drive the first clamping jaw and the second clamping jaw to move synchronously and in the same direction, the operation is more convenient for the staff, thereby improving the processing efficiency.

[0014] In some embodiments, the fastener mechanism further includes a first telescopic tube and a second telescopic tube. One end of the first telescopic tube is fixedly connected to the first side plate, and the other end of the first telescopic tube is fixedly connected to the base. One end of the second telescopic tube is fixedly connected to the second side plate, and the other end of the second telescopic tube is fixedly connected to the base.

[0015] The first side plate and the second side plate move along the first direction, and the first telescopic tube and the second telescopic tube telescope along the first direction.

[0016] When the first telescopic tube and the second telescopic tube are extended or retracted, they have a certain guiding effect, so that the first side plate, the second side plate, the first clamping jaw and the second clamping jaw move more smoothly.

[0017] In some embodiments, the fastener mechanism further includes a first gear, a first rack, a second gear and a second rack, the first gear is mounted on the first side plate, and the second gear is mounted on the second side plate.

[0018] The first rack and the second rack are mounted on the base. One end of the first rack is meshed with the first gear, and the other end of the first rack is fixedly connected to the first clamp. One end of the second rack is meshed with the second gear, and the other end of the second rack is fixedly connected to the second clamp.

[0019] The first gear and the second gear rotate in opposite directions, driving the first rack and the second rack to move in opposite directions along the first direction, so that the first clamping jaw and the second clamping jaw move away from each other or approach each other.

[0020] By arranging the first gear and the first rack to drive the first clamping jaw, and the second gear and the second rack to drive the second clamping jaw, the stability of the movement of the gear and the rack is higher, thereby improving the stability of the movement of the first clamping jaw and the second clamping jaw.

The second driving member is fixed to the first side plate, and the second driving member includes a second driving end, the second driving end is connected to the first gear, and the second driving end drives the first gear to rotate.

[0022] The third driving member is fixed to the second side plate. The third driving member includes a third driving end. The third driving end is connected to the second gear. The third driving end drives the second gear to rotate.

[0023] By providing the second driving member and the third driving member, it is convenient for workers to adjust the movement of the first clamping jaw and the second clamping jaw, thereby improving the processing efficiency.

[0024] In some embodiments, there are two polishing discs, and along the height direction of the polishing machine, the polishing discs are spaced apart from each other, and the fixing part is located between the two polishing discs. The two polishing discs can be away from each other or close to each other.

[0025] By providing two polishing discs, the two polishing discs can polish opposite sides of the workpiece at the same time, thereby improving the processing efficiency.

[0026] In some embodiments, the polishing machine further comprises a sensor, which is mounted on the base. Along the height direction of the polishing machine, a sensing mark is arranged on one side of one of the polishing discs, the sensing mark is spaced opposite to the sensor, and the sensor can identify the distance of the sensing mark.

[0027] When the polishing disc moves, the induction mark will also move with it. The sensor can identify the distance the induction mark moves to identify the distance the polishing disc moves. The staff can use the sensor to determine the moving distance of the polishing disc, which is convenient for adjusting the distance between the two polishing discs.

[0028] In the polishing machine provided in the embodiment of the present application, when the polishing disc is polishing the workpiece, the firmware part can drive the workpiece to move along the first direction, so that the polishing disc will not always polish the same position of the workpiece, and the workpiece can be polished evenly by the polishing disc, thereby increasing the flatness of the workpiece and improving the surface quality.

DETAILED DESCRIPTION

[0037] The technical scheme in the embodiment of the present application will be described clearly and completely below in conjunction with the drawings in the embodiment of the present application. For ease of understanding, the first direction is defined as the X-axis, which is parallel to the surface of the polishing disc 200 facing the workpiece, and the height direction of the polishing machine 1000 is defined as the Y-axis, which is perpendicular to the X-axis.

[0038] Please refer to Figure 1 and Figure 2 The polishing machine 1000 provided in the embodiment of the present application includes a base 100, a polishing disc 200 and a fixing mechanism 300, wherein the polishing disc 200 and the fixing mechanism 300 are installed on the base 100. The fixing mechanism 300 is provided with a fixing part 301, and the polishing disc 200 and the fixing part 301 are arranged at intervals along the height direction of the polishing machine 1000. The fixing part 301 is used to fix the workpiece to be polished, and the polishing disc 200 is used to polish the workpiece. The fixing part 301 can drive the workpiece to move along a first direction, and the first direction is parallel to the surface of the polishing disc 200 facing the workpiece.

[0039] Specifically, the base 100 is cylindrical, and a receiving cavity 101 is concavely formed on one side of the base 100 along the Y-axis direction, and the polishing disc 200 is installed in the receiving cavity 101. The fixing mechanism 300 is installed on the base 100, and the fixing mechanism 300 is provided with a fixing part 301 for fixing the workpiece, and the fixing part 301 is located on the side of the polishing disc 200 facing the positive direction of the Y-axis, and along the Y-axis direction, the fixing part 301 and the polishing disc 200 are spaced and opposite to each other.

[0040] The polishing machine 1000 also includes a first rotating motor 400. Along the Y-axis direction, the first rotating motor 400 is fixed to the side of the base 100 away from the accommodating cavity 101. The first rotating motor 400 includes a first motor shaft 401. The first motor shaft 401 extends from the outside of the accommodating cavity 101 into the accommodating cavity 101 in the positive direction of the Y-axis and is fixedly connected to the polishing disc 200.

[0041] After the workpiece is fixed to the fixing part 301, one side of the workpiece contacts the polishing disc 200. At this time, the first rotating motor 400 works, and the first motor shaft 401 rotates, so that the polishing disc 200 rotates around the Y axis, and the polishing disc 200 polishes the workpiece. During the process of the polishing disc 200 polishing the workpiece, the fixing part 301 drives the workpiece to move back and forth along the X axis, so that each position of the workpiece can be polished evenly, thereby achieving a higher flatness of the workpiece and a better surface quality of the workpiece.

[0042] In some embodiments, continue to refer to Figure 1 and Figure 2The fixing part 301 includes a first clamping jaw 302 and a second clamping jaw 303. The first clamping jaw 302 and the second clamping jaw 303 are spaced apart from each other along the first direction, and the first clamping jaw 302 and the second clamping jaw 303 can move away from or approach each other. The first clamping jaw 302 and the second clamping jaw 303 can move synchronously and in the same direction along the first direction.

[0043] Specifically, the first clamp 302 and the second clamp 303 are V-shaped or arc-shaped. Along the X-axis direction, the first clamp 302 and the second clamp 303 are spaced and opposite to each other, and the opening of the first clamp 302 and the opening of the second clamp 303 are opposite to each other. The workpiece is placed between the first clamp 302 and the second clamp 303. When the first clamp 302 and the second clamp 303 are close to each other, the workpiece is fixed. When the first clamp 302 and the second clamp 303 are away from each other, the workpiece is released.

[0044] When the first clamp 302 and the second clamp 303 move back and forth along the X-axis synchronously and in the same direction, the first clamp 302 and the second clamp 303 drive the workpiece to move back and forth along the X-axis. For example, the first clamp 302 and the second clamp 303 move at the same speed at the same time in the positive direction of the X-axis, driving the workpiece to move a distance along the positive direction of the X-axis. The first clamp 302 and the second clamp 303 then move at the same speed at the same time in the negative direction of the X-axis, driving the workpiece to move a distance along the negative direction of the X-axis. The first clamp 302 and the second clamp 303 continuously and alternately move along the positive direction of the X-axis and the negative direction of the X-axis, so that the workpiece can move back and forth during the polishing process.

[0045] In order to fix the workpiece and move the workpiece back and forth, it is only necessary to set the movable first clamping jaw 302 and the second clamping jaw 303, and there is no need to set a more complicated structure. The structure of the polishing machine 1000 provided in the embodiment of the present application is simpler, so that the design cost is reduced. At the same time, the operation of the mechanism is relatively simple, and the staff is easier to operate, thereby improving the processing efficiency.

[0046] In some embodiments, continue to refer to Figure 1 and Figure 2 The fastener mechanism 300 further includes a first side plate 304 and a second side plate 305, and the first side plate 304 and the second side plate 305 are mounted on the base 100. Along the first direction, the first side plate 304 and the second side plate 305 are located on both sides of the base 100. The first clamping jaw 302 is connected to the first side plate 304, and the second clamping jaw 303 is connected to the second side plate 305.

[0047] The first side plate 304 and the second side plate 305 can move synchronously and in the same direction along the first direction, so as to drive the first clamping jaw 302 and the second clamping jaw 303 to move synchronously and in the same direction along the first direction.

[0048] Specifically, the first side plate 304 and the second side plate 305 are long strip plates, and the length of the first side plate 304 and the second side plate 305 extends along the Y-axis direction. Along the X-axis direction, the first side plate 304 and the second side plate 305 are located on both sides of the base 100, and the first side plate 304 and the second side plate 305 are installed on the base 100, and the first side plate 304 and the second side plate 305 can move synchronously and in the same direction along the X-axis direction.

[0049] The first clamping jaw 302 is connected to the side of the first side plate 304 facing the base 100, and the second clamping jaw 303 is connected to the side of the second side plate 305 facing the base 100. The first side plate 304 and the second side plate 305 move back and forth along the X-axis synchronously and in the same direction, so as to drive the first clamping jaw 302 and the second clamping jaw 303 to move back and forth along the X-axis synchronously and in the same direction.

[0050] For example. The first side plate 304 and the second side plate 305 move at the same speed simultaneously along the positive direction of the X-axis, and the first clamp 302 and the second clamp 303 move at the same speed simultaneously along the positive direction of the X-axis, driving the workpiece to move a distance along the positive direction of the X-axis. The first side plate 304 and the second side plate 305 then move at the same speed simultaneously along the negative direction of the X-axis, and the first clamp 302 and the second clamp 303 move at the same speed along the negative direction of the X-axis, driving the workpiece to move a distance along the negative direction of the X-axis. The first side plate 304 and the second side plate 305 continuously and alternately move along the positive direction of the X-axis and the negative direction of the X-axis, driving the first clamp 302 and the second clamp 303 continuously and alternately move along the positive direction of the X-axis and the negative direction of the X-axis, so that the workpiece can move back and forth during the polishing process.

[0051] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 4 The fastener mechanism 300 further includes a linkage plate 306, one end of which is fixedly connected to the first side plate 304, and the other end of which is fixedly connected to the second side plate 305. Specifically, the linkage plate 306 is disposed on one side of the outer peripheral surface of the base 100. One end of the linkage plate 306 is bent toward the first side plate 304 to the first side plate 304, and is fixedly connected to the first side plate 304. The other end of the linkage plate 306 is bent toward the second side plate 305 to the second side plate 305, and is fixedly connected to the second side plate 305.

[0052] By setting a linkage plate 306 to connect the first side plate 304 and the second side plate 305, the first side plate 304 and the second side plate 305 can move synchronously and in the same direction, so that the first clamp 302 and the second clamp 303 can move synchronously and in the same direction. During the movement of the first clamp 302 and the second clamp 303, the relative positions of the first clamp 302 and the second clamp 303 will not change, ensuring that the workpiece can be firmly secured between the first clamp 302 and the second clamp 303, thereby preventing the workpiece from falling off.

[0053] In some embodiments, please refer to Figure 2 and Figure 3 The fastener mechanism 300 further includes a first driving member 307, which is mounted on the base 100. The first driving member 307 includes a first driving end 308, which is connected to the first side plate 304 or the second side plate 305. The first driving end 308 drives the first side plate 304 or the second side plate 305 to move, so that the first side plate 304, the linkage plate 306 and the second side plate 305 move, thereby driving the first clamping jaw 302 and the second clamping jaw 303 to move.

[0054] Specifically, the first driving member 307 can be a hydraulic rod or a linear motor. The first driving member 307 also includes a first body 309, which is connected to the first driving end 308, and the first body 309 is used to drive the first driving end 308 to extend and retract. The first driving member 307 is arranged between the first side plate 304 and the base 100, the first body 309 is fixed to the base 100, the first driving end 308 is fixedly connected to the first side plate 304, and the first side plate 304 is indirectly mounted on the base 100 through the first driving member 307.

[0055] When the first body 309 drives the first driving end 308 to extend and retract along the X-axis direction, the first driving end 308 pushes the first side plate 304 to move back and forth along the X-axis direction. Because the first side plate 304 and the second side plate 305 are fixedly connected by the linkage plate 306, the first side plate 304 and the second side plate 305 can move back and forth along the X-axis direction synchronously and in the same direction, so as to drive the first clamping jaw 302 and the second clamping jaw 303 to move back and forth along the X-axis direction synchronously and in the same direction, so that the workpiece can move back and forth along the X-axis direction.

[0056] By providing the first driving member 307 , the worker can drive the workpiece to move back and forth through the first driving member 307 , which makes the operation more convenient and thus improves the processing efficiency.

[0057] In other embodiments, the first driving member 307 may also be disposed between the second side plate 305 and the base 100, the first driving end 308 is fixedly connected to the second side plate 305, and the second side plate 305 is indirectly mounted on the base 100 through the first driving member 307. The first driving end 308 is retracted along the X direction, and the first driving end 308 pushes the second side plate 305 to move back and forth along the X axis direction. Because the first side plate 304 and the second side plate 305 are fixedly connected through the linkage plate 306, the first side plate 304 and the second side plate 305 can move back and forth along the X axis direction synchronously and in the same direction, so as to drive the first clamping jaw 302 and the second clamping jaw 303 to move back and forth along the X axis direction synchronously and in the same direction, so that the workpiece can move back and forth along the X axis direction.

[0058] Alternatively, two first driving members 307 can be provided, wherein one of the first driving members 307 is provided between the first side plate 304 and the base 100, and along the X-axis direction, the first body 309 of one of the first driving members 307 is fixedly connected to one side of the base 100, and the first driving end 308 is fixedly connected to the first side plate 304.

[0059] Another first driving member 307 is disposed between the second side plate 305 and the base 100, a first body 309 of another first driving member 307 is fixedly connected to the other side of the base 100, and a first driving end 308 is fixedly connected to the second side plate 305. The first side plate 304 and the second side plate 305 are indirectly mounted on the base 100.

[0060] One of the first driving ends 308 faces the positive direction of the X-axis, and the other first driving end 308 faces the negative direction of the X-axis, that is, the two first driving ends 308 extend and retract in opposite directions. Therefore, in order to ensure that the first side plate 304 and the second side plate 305 move synchronously and in the same direction along the X-axis, the two first driving ends 308 need to move in opposite directions. For example, when one of the first driving ends 308 extends, the other first driving end 308 contracts to ensure that the first side plate 304 and the second side plate 305 move back and forth synchronously and in the same direction along the X-axis.

[0061] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 4 The fastener mechanism 300 further includes a first telescopic tube 310 and a second telescopic tube 311. One end of the first telescopic tube 310 is fixedly connected to the first side plate 304, and the other end of the first telescopic tube 310 is fixedly connected to the base 100. One end of the second telescopic tube 311 is fixedly connected to the second side plate 305, and the other end of the second telescopic tube 311 is fixedly connected to the base 100.

[0062] The first side plate 304 and the second side plate 305 move along the first direction, and the first telescopic tube 310 and the second telescopic tube 311 telescope along the first direction.

[0063] Specifically, the first telescopic tube 310 is disposed between the first side plate 304 and the base 100 , and there are two first telescopic tubes 310 . Along the X-axis direction, one end of the first telescopic tube 310 is fixedly connected to the first side plate 304 , and the other end of the first telescopic tube 310 is fixedly connected to the base 100 .

[0064] The second telescopic tube 311 is disposed between the second side plate 305 and the base 100, and there are two second telescopic tubes 311. Along the X-axis direction, one end of the second telescopic tube 311 is fixedly connected to the second side plate 305, and the other end of the second telescopic tube 311 is fixedly connected to the base 100. When the first side plate 304 and the second side plate 305 move synchronously and in the same direction along the X-axis direction, the first telescopic tube 310 and the second telescopic tube 311 are telescoped along the X-axis direction.

[0065] By providing the first telescopic tube 310 and the second telescopic tube 311 , on the one hand, the first side plate 304 is also installed on the base 100 through the first telescopic tube 310 , and the second side plate 305 is also installed on the base 100 through the second telescopic tube 311 , and the first side plate 304 and the second side plate 305 can be installed on the base 100 more stably.

[0066] On the other hand, when the first telescopic tube 310 and the second telescopic tube 311 are extended or retracted, the first telescopic tube 310 and the second telescopic tube 311 have a certain guiding effect, so that the first side plate 304, the second side plate 305, the first clamping jaw 302 and the second clamping jaw 303 can move more smoothly.

[0067] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 4 The fastener mechanism 300 further includes a first gear 312 , a first rack 313 , a second gear 314 and a second rack 315 . The first gear 312 is mounted on the first side plate 304 , and the second gear 314 is mounted on the second side plate 305 .

[0068] The first rack 313 and the second rack 315 are mounted on the base 100. One end of the first rack 313 is meshed with the first gear 312, and the other end of the first rack 313 is fixedly connected to the first clamp 302. One end of the second rack 315 is meshed with the second gear 314, and the other end of the second rack 315 is fixedly connected to the second clamp 303.

[0069] The first gear 312 and the second gear 314 rotate in opposite directions, driving the first rack 313 and the second rack 315 to move in opposite directions along the first direction, so that the first clamping jaw 302 and the second clamping jaw 303 move away from or approach each other.

[0070] Specifically, the first gear 312 and the second gear 314 are helical gears, the first gear 312 is fixed to the first side plate 304, and the second gear 314 is fixed to the second side plate 305. The lengths of the first rack 313 and the second rack 315 extend along the X-axis direction. The base 100 is provided with a first guide hole 102 and a second guide hole 103, which penetrate the outer peripheral surface of the base 100 and the cavity side surface of the accommodating cavity 101, and along the X-axis direction, the first guide hole 102 and the second guide hole 103 are spaced and opposite to each other.

[0071] One end of the first rack 313 passes through the first guide hole 102 into the accommodating chamber 101 and is connected to the first clamping jaw 302.

[0080] On the contrary, if the second driving end 318 and the third driving end 319 rotate in opposite directions, the first clamping jaw 302 and the second clamping jaw 303 will move away from each other.

[0081] By providing the second driving member 316 and the third driving member 317 , it is convenient for the staff to adjust the movement of the first clamping jaw 302 and the second clamping jaw 303 , thereby improving the processing efficiency.

[0082] In some embodiments, please refer to Figure 1The number of the polishing discs 200 is two, and along the height direction of the polishing machine 1000, the polishing discs 200 are spaced apart from each other, and the fixing part 301 is located between the two polishing discs 200. The two polishing discs 200 can be away from each other or close to each other.

[0083] Specifically, a mounting bracket 104 is convexly provided on one side of the base 100 facing the positive direction of the Y axis. The mounting bracket 104 is an L-shaped bracket. The mounting bracket 104 includes a support section 105 and a mounting section 106. The support section 105 and the mounting section 106 are plate-shaped. The support section 105 and the mounting section 106 are connected at an angle, and the angle of the angle is 90 degrees. The length of the support section 105 extends along the Y axis. Along the Y axis, the mounting section 106 is spaced apart from the accommodating cavity 101.

[0084] The polishing machine 1000 further includes a fifth driving member 500 and a second rotating motor 600. The fifth driving member 500 can be a hydraulic rod or a linear motor. The fifth driving member 500 includes a fifth body 501 and a fifth driving end 502. The fifth body 501 and the fifth driving end 502 are connected. The fifth body 501 drives the fifth driving end 502 to extend and retract.

[0085] The fifth body 501 is fixed to the side of the mounting section 106 away from the accommodating chamber 101, and the fifth driving end 502 passes through the mounting section 106 in the negative direction of the Y axis. The second rotary motor 600 is fixed to the fifth driving end 502, and the second rotary motor 600 also includes a second motor shaft 601, and the second motor shaft 601 is fixedly connected to another polishing disc 200. At this time, along the Y axis direction, the two polishing discs 200 are spaced and opposite to each other, and the first clamping jaw 302 and the second clamping jaw 303 are arranged between the two polishing discs 200, and the distance between the first clamping jaw 302 and the second clamping jaw 303 and the polishing disc 200 in the accommodating chamber 101 is 2 cm.

[0086] When polishing a workpiece, the fifth driving member 500 is started, the fifth body 501 drives the fifth driving end 502 to contract, and the fifth driving end 502 drives the second rotating motor 600 and the polishing disc 200 to move along the positive direction of the Y axis to increase the distance between the two polishing discs 200. Then the workpiece is placed on the surface of the polishing disc 200 in the accommodating cavity 101, and the second driving member 316 and the third driving member 317 are started, and the first clamping jaw 302 and the second clamping jaw 303 clamp the workpiece. Then the fifth driving member 500 is driven, and the fifth driving end 502 is extended, pushing the second rotating motor 600 and the polishing disc 200 to move along the negative direction of the Y axis, so that the two polishing discs 200 are close to each other and contact the opposite sides of the workpiece along the Y axis.

[0087] Finally, the first rotating motor 400, the second rotating motor 600 and the first driving member 307 are started, and the two polishing discs 200 polish the workpiece. The first driving member 307 drives the first side plate 304 and the second side plate 305 to move back and forth synchronously and in the same direction along the X-axis, so as to drive the first clamping jaw 302 and the second clamping jaw 303 to move back and forth synchronously and in the same direction along the X-axis, so that the workpiece can move back and forth between the two polishing discs 200 when the polishing discs 200 are polishing.

[0088] By providing two polishing discs 200, the two polishing discs 200 can polish opposite sides of the workpiece at the same time, thereby improving the processing efficiency.

[0089] In some embodiments, the two polishing discs 200 rotate in opposite directions. When the two polishing discs 200 with opposite rotation directions polish the opposite sides of the workpiece, one of the polishing discs 200 rotates clockwise to polish the workpiece, and the workpiece tends to rotate clockwise. At this time, the other polishing disc 200 rotates counterclockwise to polish the workpiece. In addition to polishing the workpiece, the polishing disc 200 also has the function of preventing the workpiece from rotating clockwise, so that the workpiece will not rotate at will during polishing.

[0090] In some embodiments, please refer to Figure 2 The polishing machine 1000 further includes a sensor 700, which is mounted on the base 100. Along the height direction of the polishing machine 1000, a sensing mark 201 is provided on one side of one polishing disc 200, and the sensing mark 201 is spaced opposite to the sensor 700, and the sensor 700 can identify the distance of the sensing mark 201.

[0091] Specifically, the sensor 700 is installed on the side of the installation section 106 facing the polishing disc 200, and the sensing mark 201 is arranged on the polishing disc 200 connected to the second rotating motor 600, and the sensing mark 201 is arranged on the side of the polishing disc 200 facing the sensor 700. Along the Y-axis direction, the sensor 700 and the sensing mark 201 are spaced and opposite to each other.

[0092] When the fifth driving end 502 drives the polishing disc 200 to move, the sensing mark 201 moves with the polishing disc 200, and the sensor 700 can identify the moving distance of the sensing mark 201 to identify the moving distance of the polishing disc 200. Therefore, the staff can judge how far the polishing disc 200 has moved through the sensor 700, so that the staff can adjust the distance between the two polishing discs 200.

[0093] In some embodiments, please refer to Figure 1 and Figure 5The polishing disc 200 is provided with a chip groove 202 on one side facing the fixing part 301. Specifically, a center hole 203 is provided at the center of the polishing disc 200, and the center hole 203 penetrates the two opposite sides of the polishing disc 200 along the thickness direction. There are multiple chip grooves 202, and the chip grooves 202 penetrate the inner circumference of the center hole 203 and the outer circumference of the polishing disc 200.

[0094] When the workpiece is polished, the generated dust falls into the chip discharge groove 202 and is discharged from the central hole 203 or the side of the polishing disc 200 to prevent the dust from interfering with the polishing of the workpiece by the polishing disc 200.

[0095] In some embodiments, please refer to Figure 2 The polishing machine 1000 further includes a liquid spraying device (not shown), which includes a nozzle 800. The nozzle 800 is fixed to the side of the base 100 facing the positive direction of the Y axis. The nozzle 800 is used to spray polishing liquid toward the workpiece when polishing the workpiece, so that the workpiece is easier to polish and the surface after polishing is smoother.

[0096] In some embodiments, please refer to Figure 2 The base is also provided with a drainage hole 107 and a drainage pipe 900. The drainage hole 107 penetrates the bottom surface of the accommodating cavity 101 and the side of the base 100 away from the bottom surface of the accommodating cavity 101. The drainage pipe 900 is located outside the accommodating cavity, and one end of the drainage pipe 900 is connected to the drainage hole 107. By providing the drainage pipe 900, the polishing liquid falling into the accommodating cavity 101 can be discharged from the drainage pipe 900.

[0097] In some embodiments, the first side plate 304 is provided with a first guide sleeve 322, and one end of the first rack 313 away from the base 100 passes through the first guide sleeve 322, and the first rack 313 can slide in the first guide sleeve 322. The second side plate 305 is provided with a second guide sleeve 323, and one end of the second rack 315 away from the base 100 passes through the second guide sleeve 323, and the second rack 315 can slide in the second guide sleeve 323.

[0098] The first guide sleeve 322 and the first guide hole 102 guide the first rack 313, and the second guide sleeve 323 and the second guide hole 103 guide the second rack 315. By providing the first guide sleeve 322 and the second guide sleeve 323, the first rack 313 and the second rack 315 can move more smoothly along the X-axis direction, so that the movement of the first clamping jaw 302 and the second clamping jaw 303 is more stable.
