Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of surface treatment, in particular to a polishing device. BACKGROUND

[0002] In the field of mechanical processing, workpiece polishing is an important process. Traditional polishing devices usually adopt the way of fixing the polishing head and the position of the workpiece, so that the polishing part can only polish the local fixed position of the workpiece. This way is difficult to ensure comprehensive and uniform polishing of multiple positions of the workpiece, resulting in inconsistent surface quality of the workpiece, and additional manual operation or complex tooling adjustment is needed to realize polishing of other positions of the workpiece, which increases the production cost and processing time. Some traditional polishing equipment lacks effective workpiece moving and positioning mechanism. During the polishing process, the relative position between the workpiece and the polishing part cannot be flexibly adjusted, resulting in frequent interruption of the polishing process, and the polishing process continues after the position of the workpiece is adjusted again. This not only reduces the polishing efficiency, but also may affect the final polishing quality of the workpiece due to the error accumulation caused by multiple adjustments.

[0026] Specifically, please refer to Figure 1 , Figure 2 and Figure 3The moving mechanism 10 comprises a moving assembly 11 and a positioning assembly 12 connected to the moving assembly 11, the moving assembly 11 is used for moving the positioning assembly 12 horizontally, and the positioning assembly 12 is used for fixing the workpiece 200. The moving assembly 11 is used for moving the positioning assembly 12 in an X-Y plane, and the positioning assembly 12 supports and positions the workpiece 200. The positioning assembly 12 can adopt an inner support structure to hold the workpiece 200, when the workpiece 200 is held by the inner support structure, the polishing mechanism 30 can polish the upper surface or the side surface of the workpiece 200. Or the positioning assembly 12 can adopt a pressing structure to press the workpiece 200, for example, the workpiece 200 is supported by a support structure made of a magnetic material, and a magnet or other mechanism is arranged on the other side of the workpiece 200 to press the workpiece 200, the magnet is attracted to the magnetic support structure to clamp and fix the workpiece 200, so that the stability of the positioning assembly 12 for fixing the workpiece 200 is improved, and the side surface of the workpiece 200 can be polished by the polishing mechanism 30.

[0027] The vibrating mechanism 20 comprises a support frame 21, a vibrating assembly 22 and a connecting assembly 23, the support frame 21 extends along the Z-axis direction, the moving assembly 11 is fixedly connected to one end of the support frame 21, the vibrating assembly 22 is connected to the support frame 21, and comprises a vibrating driving member 221, a crank connecting rod unit 222 and a sliding plate 223, the vibrating driving member 221 is connected to one end of the support frame 21 close to the moving assembly 11, one end of the crank connecting rod unit 222 is connected to the vibrating driving member 221, and the other end is connected to the sliding plate 223, the connecting assembly 23 is movably arranged at the other end of the support frame 21 and extends along the X-axis direction, and the connecting assembly 23 is fixedly connected to the sliding plate 223.

[0028] The support frame 21 can be a frame structure or a box structure, and provides stable support for the vibrating assembly 22 and the polishing mechanism 30. The vibrating driving member 221 can be a motor or a rotary cylinder. The crank connecting rod unit 222 is used for converting the rotary motion output by the vibrating driving member 221 into up-down motion, so that the vibrating driving member 221 can drive the sliding plate 223 to move up and down through the crank connecting rod unit 222.

[0029] The polishing mechanism 30 is connected to the connecting assembly 23 and comprises a polishing member 31 arranged on the upper side of the moving assembly 11, and the polishing member 31 is used for polishing the workpiece 200.

[0030] When the polishing member 31 polishes the workpiece 200, the moving assembly 11 drives the workpiece 200 to move around the polishing member 31 through the positioning assembly 12, so that the polishing member 31 polishes multiple positions of the workpiece 200, and the vibration driving member 221 drives the sliding plate 223 and the connecting assembly 23 to vibrate in the Z-axis direction through the crank linkage unit 222, thereby driving the polishing member 31 to vibrate in the Z-axis direction. In this way, during the polishing process of the workpiece 200 by the polishing member 31, the vibration of the polishing member 31 can make the polishing member 31 better contact the surface of the workpiece 200, which helps to remove the tiny defects on the surface of the workpiece 200, makes the polishing more uniform and fine, and thus improves the polishing effect.

[0031] The polishing device 100 provided by the embodiment of the present application can carry the workpiece 200 through the positioning assembly 12 in the moving mechanism 10, and can move the positioning assembly 12 and the workpiece 200 through the moving assembly 11 to move the workpiece 200 to a position opposite to the polishing mechanism 30, and then cooperate with the polishing mechanism 30 to polish the workpiece 200. During the polishing process of the workpiece 200 by the polishing member 31, the moving assembly 11 can drive the workpiece 200 fixed on the positioning assembly 12 to move around the polishing member 31, so that the polishing member 31 can polish multiple positions of the workpiece 200, overcoming the limitation of the conventional polishing device 100 that can only polish the fixed position, thereby improving the comprehensiveness and uniformity of the polishing of the surface of the workpiece 200, and helping to improve the overall quality of the workpiece 200. Without frequently interrupting the polishing operation to re-adjust the position of the workpiece 200, the continuity of the polishing process can be ensured, the time wasted due to the adjustment of the position of the workpiece 200 is reduced, and thus the polishing efficiency is improved.

[0032] During the polishing process, the vibration driving member 221 drives the crank linkage unit 222 to move, the crank linkage unit 222 converts the rotary motion output by the vibration driving member 221 into up-down motion, so that the vibration driving member 221 can drive the sliding plate 223 to move up and down through the crank linkage unit 222, the sliding plate 223 drives the connecting assembly 23 to vibrate, and then drives the polishing member 31 to vibrate. This vibration can make the polishing member 31 better contact the surface of the workpiece 200, which helps to remove the tiny defects on the surface of the workpiece 200, makes the polishing more uniform and fine, and thus improves the polishing effect.

[0033] In some embodiments, referring to Figure 2 and Figure 3 , the crank linkage unit 222 includes a first eccentric wheel 2221, a first crank 2222, a connecting rod 2223, a second crank 2224, and a second eccentric wheel 2225.

[0034] The first eccentric wheel 2221 is connected to the vibration driving member 221, the first crank 2222 is connected to the first eccentric wheel 2221, the connecting rod 2223 is slidably connected to the support frame 21 along the Z-axis direction and is rotatably connected to the first crank 2222 away from the first eccentric wheel 2221, the second crank 2224 is rotatably connected to the connecting rod 2223 away from the first crank 2222, and the second eccentric wheel 2225 is rotatably connected to the connecting assembly 23. The end of the second crank 2224 away from the connecting rod 2223 is connected to the second eccentric wheel 2225.

[0035] The vibration driving member 221 drives the first eccentric wheel 2221 to rotate, and the first eccentric wheel 2221 drives the first crank 2222 to swing, and the first crank 2222 drives the connecting rod 2223 to move along the Z-axis direction, and the connecting rod 2223 drives the second crank 2224 to move, and the second crank 2224 drives the second eccentric wheel 2225 to vibrate, and the second eccentric wheel 2225 drives the sliding plate 223 and the connecting assembly 23 to vibrate along the Z-axis direction, and the sliding plate 223 and the connecting assembly 23 drive the polishing member 31 to vibrate along the Z-axis direction.

[0036] The first eccentric wheel 2221 is a disc structure, the first eccentric wheel 2221 is connected to the rotating shaft of the vibration driving member 221, and the vibration driving member 221 drives the first eccentric wheel 2221 to rotate. The first crank 2222 can be a rod structure, and the connection position of the first crank 2222 and the first eccentric wheel 2221 is away from the center of the first eccentric wheel 2221, so that the first eccentric wheel 2221 can drive one end of the first crank 2222 to swing eccentrically. The connecting rod 2223 can be a rod structure, the connecting rod 2223 is rotatably connected to the first crank 2222, and the first crank 2222 can drive the connecting rod 2223 to reciprocate along the Z-axis direction. The second crank 2224 can be a rod structure, and the connecting rod 2223 can drive the second crank 2224 to move. The second eccentric wheel 2225 can be a cylindrical structure, and bearings or other structures can be arranged between the second eccentric wheel 2225 and the sliding plate 223 to improve the stability of the rotatable connection between the second eccentric wheel 2225 and the sliding plate 223.

[0037] The vibration of the connecting assembly 23 is realized through the cooperation of the vibration driving member 221, the first eccentric wheel 2221, the first crank 2222, the connecting rod 2223, the second crank 2224, the second eccentric wheel 2225, and the sliding plate 223. The multi-stage transmission structure can adjust the parameters of each component according to actual needs, such as the eccentricity of the first eccentric wheel 2221 and the second eccentric wheel 2225, the length of the first crank 2222 and the second crank 2224, and the like, so as to accurately adjust the vibration frequency and amplitude of the polishing member 31 in the Z-axis direction, so as to adapt to the requirements of different workpiece 200 materials and shapes on polishing vibration, and improve the polishing quality. The first eccentric wheel 2221 is connected with the first crank 2222, and the second crank 2224 is connected with the second eccentric wheel 2225, which can effectively convert the rotary motion of the vibration driving member 221 into the reciprocating vibration of the sliding plate 223 and the connecting assembly 23. At the same time, the connecting rod 2223 connects the first crank 2222 and the second crank 2224, which ensures the transmission and continuity of the motion, so that the vibration can be stably and effectively transmitted to the polishing member 31, thereby enhancing the vibration effect and further improving the uniformity and fineness of polishing.

[0038] In some embodiments, referring to Figure 2 and Figure 3 , the crank connecting rod unit 222 further comprises a sliding rail 2226 and a sliding block 2227.

[0039] The sliding rail 2226 is connected to the support frame 21 and extends along the Z-axis direction. The sliding rail 2226 is arranged between the first eccentric wheel 2221 and the second eccentric wheel 2225, and the sliding block 2227 is slidingly connected to the sliding rail 2226. The end of the first crank 2222 away from the first eccentric wheel 2221 is rotatably connected to the sliding block 2227, and the end of the connecting rod 2223 close to the first eccentric wheel 2221 is fixedly connected to the sliding block 2227. Through the cooperation of the sliding block 2227 and the sliding rail 2226, the connecting rod 2223 can maintain a stable straight motion track during the driving motion by the first crank 2222, avoiding the problem of unstable vibration transmission caused by motion deviation, and ensuring that the vibration can be accurately and stably transmitted from the vibration driving member 221 to the connecting assembly 23, and then to the polishing member 31.

[0040] In some embodiments, the crank connecting rod unit 222 further comprises a limiting block 2228, which is connected to the support frame 21 and arranged at the end close to the second eccentric wheel 2225 of the sliding rail 2226, and the connecting rod 2223 is slidingly inserted into the limiting block 2228. The limiting block 2228 limits the end of the connecting rod 2223 connected to the second crank 2224, which can improve the stability of the motion of the connecting rod 2223 and further ensure the accuracy and stability of the motion of the entire vibration assembly 22.

[0041] In some embodiments, the vibration assembly 22 further comprises an auxiliary driving member 224 connected to the end of the support frame 21 away from the moving assembly 11, and the auxiliary driving member 224 is connected with the second eccentric wheel 2225, and the auxiliary driving member 224 is used to drive the second eccentric wheel 2225 to rotate. The auxiliary driving member 224 can be a rotating motor, a rotating cylinder or other driving devices. In the embodiment, the rotation speed of the auxiliary driving member 224 is consistent with the rotation speed of the vibration driving member 221 driving the second eccentric wheel 2225 to rotate through the first crank 2222, the connecting rod 2223 and the second crank 2224. By setting the auxiliary driving member 224, the vibration driving member 221 can assist the second eccentric wheel 2225 to rotate, and in turn drive the sliding plate 223 to move back and forth, thereby avoiding the power shortage of the vibration driving member 221 causing the second eccentric wheel 2225 and the sliding plate 223 to be unable to move through the first crank 2222, the connecting rod 2223 and the second crank 2224. At the same time, by setting the auxiliary driving member 224, the vibration assembly 22 is provided with an additional power source, so that the movement of the vibration assembly 22 is more complex and diversified, and compared with the case of being driven by only the vibration driving member 221, more abundant vibration modes and frequency combinations can be generated, so as to better adapt to the polishing needs of different workpieces 200.

The connecting arm 231 can be a columnar structure, a frame structure or the like. In the embodiment, the connecting arm 231 is a mouth-shaped structure, one side of which is movably connected with the support frame 21 along the Z-axis direction together with the sliding plate 223, or is movably connected through a limiting pin or the like, so that the vibration assembly 22 can drive the connecting arm 231 to vibrate in the Z-axis direction.

[0044] The connecting plate 232 is connected to the end of the connecting arm 231 away from the support frame 21 and is arranged on the lower side of the connecting arm 231. The connecting plate 232 can be a plate structure, and is used to support the connecting member 233 and transmit the action force of vibration.

[0045] The connecting piece 233 comprises a supporting part 2331 and a plurality of connecting parts 2332 connected with the supporting part 2331, the plurality of connecting parts 2332 are inserted into the end of the connecting arm 231 away from the supporting frame 21 and abut against the upper side of the connecting plate 232, the supporting part 2331 is arranged in a spaced manner with the connecting arm 231, and the polishing mechanism 30 is connected to the side of the supporting part 2331 away from the plurality of connecting parts 2332. The connecting part 2332 can be in a columnar or strip structure, the number of the connecting part 2332 can be two or three, and the plurality of connecting parts 2332 can be inserted into the connecting arm 231 in an adjustable connecting manner, so as to adjust the distance between the supporting part 2331 and the connecting arm 231. The supporting part 2331 can be in a plate structure, and the polishing mechanism 30 is connected thereto.

[0046] In some embodiments, referring to Figure 1 , Figure 2 and Figure 4 , the connecting assembly 23 further comprises a vibrating box 234, a rotating driving piece 235, a transmission piece 236 and a roller shaft 237.

[0047] The vibration box 234 is fixedly connected to the lower side of the connecting plate 232, and the side of the vibration box 234 facing the connecting plate 232 is provided with a slope 2341 connected with the connecting plate 232, and the vibration box 234 is internally provided with a containing cavity 2342. A rotating driving member 235 is arranged in the containing cavity 2342, a transmission member 236 is arranged in the containing cavity 2342 and connected with the rotating driving member 235, a roller shaft 237 is connected with the vibration box 234 and penetrates the vibration box 234 along the Y-axis direction, the transmission member 236 is connected with the roller shaft 237, and the rotating driving member 235 drives the roller shaft 237 to rotate around the Y-axis direction through the transmission member 236. The vibration box 234 is a special-shaped box structure and can be arranged to be inclined downward along the X-axis direction, the rotating driving member 235 can be a stepping motor, the transmission member 236 can be a transmission belt or a transmission chain, and the roller shaft 237 can be a cylindrical structure or a bearing structure. The rotating driving member 235 can drive the roller shaft 237 to rotate through the transmission member 236, and then the roller shaft 237 can vibrate. When the vibration box 234 vibrates up and down with the connecting plate 232, the roller shaft 237 can provide an action force perpendicular to the slope 2341 to the vibration box 234, and the included angle between the action force and the Z-axis direction is an acute angle. It can be understood that the vibration assembly 22 drives the connecting arm 231 to vibrate up and down along the Z-axis direction, and then drives the connecting plate 232 to vibrate up and down, that is, the action force exerted by the connecting arm 231 on the vibration box 234 is along the Z-axis direction upward or downward. It can be understood that the direction of the action force exerted by the roller shaft 237 on the vibration box 234 intersects with the direction of the action force exerted by the connecting arm 231 on the vibration box 234, and since the action force exerted by the connecting arm 231 on the vibration box 234 changes at any time, the action force received by the vibration box 234 is out of order, so that the vibration box 234 vibrates out of order, and then the action force of the vibration box 234 on the connecting part 2332 is also out of order. The connecting part 2332 drives the polishing mechanism 30 to vibrate out of order, and improves the polishing effect of the polishing piece 31 on the workpiece 200.

[0048] In some embodiments, referring to Figure 1 and Figure 2 , the polishing mechanism 30 further comprises a lifting driving member 32 and a polishing driving member 33.

[0049] The lifting driving member 32 is connected to one end of the connecting assembly 23 away from the support frame 21, and can be a telescopic air cylinder, a telescopic motor or other driving device. In this embodiment, the lifting driving member 32 is connected to the connecting part 2332 of the connecting piece 233.

[0050] The polishing driving member 33 is connected to the lifting driving member 32, and the polishing driving member 33 is connected with the polishing piece 31. The polishing driving member 33 can be a rotary motor, a rotary air cylinder or other driving device.

[0051] The lifting driving member 32 is configured to drive the polishing member 31 and the polishing driving member 33 to lift together, so that the polishing member 31 abuts against the workpiece 200. The polishing driving member 33 is configured to drive the polishing member 31 to rotate, so as to polish the workpiece 200.

[0052] The lifting driving member 32 is configured to adjust the position of the polishing driving member 33 and the polishing member 31 in the Z-axis direction, so that the polishing member 31 corresponds to the workpiece 200 in the Z-axis direction. The polishing driving member 33 can provide stable power for the polishing member 31, and ensure that the polishing member 31 polishes the workpiece 200 at a stable speed.

[0053] In some embodiments, referring to Figure 1 and Figure 5 , the polishing member 31 comprises a polishing head 311 and a plurality of sandpapers 313.

[0054] The polishing head 311 is connected to the polishing driving member 33. The polishing head 311 is provided with a plurality of accommodating grooves 312 around the axis of the polishing head 311. The plurality of sandpapers 313 are arranged in the plurality of accommodating grooves 312, respectively. The plurality of sandpapers 313 are configured to polish the workpiece 200.

[0055] The number of the accommodating grooves 312 can be four, six, nine, etc. The specific number can be set according to actual conditions, which is not limited herein. The number of the sandpapers 313 corresponds to the number of the accommodating grooves 312, such as four, six, nine, etc. One sandpaper 313 is arranged in each accommodating groove 312. The extension direction of the groove bottom of the accommodating groove 312 can be parallel to the Z-axis direction, or intersected with the Z-axis direction. When the extension direction of the groove bottom of the accommodating groove 312 is parallel to the Z-axis direction, the extension direction of the sandpaper 313 in the accommodating groove 312 is parallel to the Z-axis direction. The sandpaper 313 can polish the vertical side of the workpiece 200. When the extension direction of the groove bottom of the accommodating groove 312 is intersected with the Z-axis direction, the extension direction of the sandpaper 313 in the accommodating groove 312 is intersected with the Z-axis direction, i.e. the sandpaper 313 is arranged obliquely. The sandpaper 313 can polish the side angle of the workpiece 200. In the embodiment, the extension direction of the groove bottom of the accommodating groove 312 can be set in multiple ways, so as to polish the side and side angle of the workpiece 200, and improve the polishing effect.

[0056] The polishing head 311 is provided with a plurality of accommodating grooves 312 around the side, and the sandpapers 313 are arranged in the accommodating grooves 312. The plurality of sandpapers 313 can polish the workpiece 200 at the same time, which improves the polishing efficiency. The accommodating grooves 312 are arranged around the axis of the polishing head 311, so that the sandpapers 313 are uniformly distributed, and the workpiece 200 can be polished from different angles, which ensures the uniformity of polishing, and avoids the problem of local over-polishing or insufficient polishing. Moreover, the sandpapers 313 can be replaced individually when they are worn, which reduces the maintenance cost and downtime, and prolongs the service life of the polishing member 31.

[0057] In some embodiments, referring to Figure 1 , the moving assembly 11 comprises a first displacement driving member 111 and a second displacement driving member 112 connected to the first displacement driving member 111, the first displacement driving member 111 is arranged close to the support frame 21 and is used to move the second displacement driving member 112 along the X-axis direction, and the second displacement driving member 112 is connected with the positioning assembly 12 and is used to move the positioning assembly 12 along the Y-axis direction. The first displacement driving member 111 and the second displacement driving member 112 can be linear modules or other driving devices. By arranging the first displacement driving member 111 and the second displacement driving member 112, the positioning assembly 12 and the workpiece 200 can be freely moved in the X-Y plane, and the workpiece 200 can be rotated around the polishing member 31 when the polishing member 31 polishes the workpiece 200, so that the polishing member 31 polishes the periphery of the workpiece 200, and the polishing efficiency is improved.

[0058] The working process of the polishing device 100 provided by the embodiments of the present application is as follows:

[0059] Firstly, the workpiece 200 is placed on the positioning assembly 12 of the moving mechanism 10 and is fixed, and the first displacement driving member 111 and the second displacement driving member 112 in the moving assembly 11 can adjust the position of the workpiece 200 in the horizontal plane as needed, so that the workpiece 200 can be accurately moved to the area to be polished.

[0060] Then, the lifting driving member 32 of the polishing mechanism 30 drives the polishing driving member 33 to move, so that the polishing member 31 connected to the polishing driving member 33 corresponds to the workpiece 200 in the Z-axis direction, the workpiece 200 is abutted to the polishing member 31 by the first displacement driving member 111 and the second displacement driving member 112, and the polishing driving member 33 starts to work to drive the polishing member 31 to polish the workpiece 200.

[0061] During the polishing process, the vibration mechanism 20 starts to work, the vibration driving member 221 drives the first crank 2222 to swing through the first eccentric wheel 2221, the first crank 2222 drives the second crank 2224 to move through the connecting rod 2223, and the second crank 2224 drives the sliding plate 223 and the connecting assembly 23 to vibrate in the Z-axis direction through the second eccentric wheel 2225. The vibration of the connecting assembly 23 is transmitted to the polishing member 31, so that the polishing member 31 reciprocates in the Z-axis direction. At the same time, the second eccentric wheel 2225 is also driven to rotate by the auxiliary driving member 224, so as to further enhance the vibration effect.

[0062] The first displacement driving member 111 and the second displacement driving member 112 continuously drive the workpiece 200 to move around the polishing member 31 through the positioning assembly 12, so that the polishing member 31 can polish multiple positions of the workpiece 200.
