Description

Technical Field

[0001] The present application relates to the technical field of grinding equipment, and particularly relates to an eccentric grinding mechanism and a processing equipment. Background Art

[0002] In actual production and processing, it is usually necessary to grind the surface of the processed product so that the surface of the product meets the grinding requirements. At present, a manipulator is usually used to drive a pneumatic grinding head and a grinding piece to grind the surface of the product. However, since the rotational speed of the pneumatic grinding head is relatively low and is driven by a gas source, the grinding cutting force of the grinding piece on the surface of the product is uneven, resulting in defects such as grinding marks and grinding tangent lines on the surface of the product. Moreover, since the grinding piece usually grinds the surface of the product in a self-rotating manner under the drive of the pneumatic grinding head, defects such as grinding static points are likely to appear on the surface of the product. The above-mentioned defects will all cause the surface of the product to not meet the grinding requirements. The grinding static point can be understood as when the grinding piece grinds the surface of the product in a self-rotating manner, the center of the self-rotation of the grinding piece cannot grind the surface of the product, thus forming a grinding static point. Summary of the Utility Model

[0003] In view of the above, it is necessary to provide an eccentric grinding mechanism and a processing equipment to eliminate defects such as grinding marks, grinding tangent lines, and grinding static points on the surface of the product, so that the surface of the product meets the grinding requirements.

One end of the first counterweight is connected to the connecting shaft, and the other end of the first counterweight extends toward the axis of the eccentric hole in a direction perpendicular to the axis of the connecting shaft. The axis of the second counterweight is coaxially arranged with the axis of the connecting shaft. One end of the second counterweight protrudes relatively from one end of the first counterweight, and the other end of the first counterweight protrudes relatively from the other end of the second counterweight. The eccentric hole is formed in the second counterweight or the eccentric hole penetrates through the second counterweight and extends to the first counterweight.

[0011] In some embodiments, the grinding wheel assembly includes a connecting rod and a grinding wheel. One end of the connecting rod is connected to the bearing member, the other end of the connecting rod is connected to one end of the grinding wheel, and the other end of the grinding wheel is connected to the buffer assembly.

[0012] In some embodiments, the grinding wheel assembly further includes a seal and a fixing member. The seal is sleeved on the connecting rod and is located on the side of the eccentric hole facing the grinding wheel, and the fixing member is located in the eccentric hole and abuts against the side of the connecting rod passing through the bearing member.

[0013] In some embodiments, the buffer assembly includes a buffer member and an adhesive member connected to each other. The buffer member is connected to the grinding wheel assembly, and the adhesive member is used for detachably pasting an external grinding member.

[0014] In some embodiments, the buffer member is a foam member or a rubber member, and the adhesive member is a magic tape.

[0015] In some embodiments, the connection assembly includes a tool handle and a collet. One end of the tool handle is used for connecting to an external driving spindle, the other end of the tool handle is connected to one end of the collet, and the other end of the collet clamps the connecting shaft.

[0016] The embodiment of the present application further provides a processing device, including:

[0017] A machine table;

[0018] A carrying mechanism, arranged on the machine table, and the carrying mechanism is used for carrying a product to be processed;

[0019] A driving spindle, arranged on the machine table and located above the carrying mechanism;

[0020] The eccentric grinding mechanism according to any one of the above technical solutions, wherein the connection assembly of the eccentric grinding mechanism is connected to the driving spindle, and the driving spindle is used for driving the eccentric grinding mechanism to rotate to grind the product.

[0021] In some embodiments, the processing equipment further includes a first driving mechanism and a second driving mechanism. The first driving mechanism is disposed on the machine table and connected to the driving main shaft. The first driving mechanism is configured to drive the driving main shaft and the eccentric grinding mechanism to approach or move away from the carrying mechanism in a first direction. The second driving mechanism is disposed on the machine table and connected to the carrying mechanism. The second driving mechanism is configured to drive the carrying mechanism to move in a second direction and / or a third direction.

[0022] In some embodiments, the processing equipment further includes a tool magazine. The tool magazine is located on one side of the driving main shaft and above the carrying mechanism. The tool magazine includes a tool compartment, a connecting member, and an elastic member. The tool compartment is movably connected to the driving main shaft. One end of the connecting member is rotatably connected to the tool compartment. The other end of the connecting member moves along a preset trajectory on the driving main shaft. Two ends of the elastic member are respectively connected to the tool compartment and the driving main shaft. The elastic member is located above the connecting member.

[0023] When the above-mentioned eccentric grinding mechanism and the processing equipment including the eccentric grinding mechanism are actually used, a product to be ground and processed is placed on the carrying mechanism. The other end of the buffer assembly of the eccentric grinding mechanism is connected to a grinding member. The driving main shaft drives the eccentric grinding mechanism to rotate. The connecting assembly and the connecting shaft of the eccentric grinding mechanism rotate coaxially with the driving main shaft. Since the axis of the eccentric hole is eccentrically arranged with respect to the axis of the connecting shaft, the grinding disc assembly, the buffer assembly, and the grinding member rotate eccentrically relative to the driving main shaft. The grinding member grinds the surface of the product. Since the grinding member rotates eccentrically relative to the driving main shaft and the grinding member can also rotate by itself through the bearing member when following the connecting assembly to rotate eccentrically, the front and rear grinding circles of the grinding member can overlap each other. The grinding member alternately grinds the surface of the product, so that the grinding static points can be offset. And since the eccentric grinding mechanism is driven by the driving main shaft, the grinding cutting force when the eccentric grinding mechanism drives the grinding member to grind the surface of the product is uniform, which is beneficial to improving the defects such as grinding marks and grinding tangents on the surface of the product, so that the surface of the product meets the grinding requirements.

[0024] In addition, since the eccentric grinding mechanism is driven by the driving main shaft, the eccentric grinding mechanism can achieve high-speed and high-feed rotation. The grinding performance of the eccentric grinding mechanism is stable, which is beneficial to improving the grinding efficiency and grinding quality. And the rotation speed and feed of the eccentric grinding mechanism can be adjusted according to the material of different products and the magnitude of the required grinding cutting force, so as to meet the grinding requirements of different products and improve the versatility of the eccentric grinding mechanism. The buffer assembly buffers the acting force transmitted from the grinding member, so that the eccentric grinding mechanism realizes flexible grinding of the product. Description of the Drawings

[0066] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0067] See also Figure 1 The embodiment of the present application provides an eccentric grinding mechanism 100. The eccentric grinding mechanism 100 is used to grind the surface of a product, which can eliminate grinding static points, improve grinding marks, grinding tangents and other defects on the surface of the product, and make the surface of the product meet the grinding requirements.

[0068] Please refer to Figure 1 and Figure 2 The eccentric grinding mechanism 100 includes a connecting assembly 10, an eccentric assembly 20, a bearing member 30, a grinding disc assembly 40 and a buffer assembly 50.

[0069] The connecting assembly 10 is used to connect an external drive spindle (not shown), and the external drive spindle can drive the connecting assembly 10 to rotate, move, etc., and then drive the eccentric grinding mechanism 100 to rotate, move, etc. The eccentric assembly 20 includes a connecting shaft 21 and a balancing member 22. One end of the connecting shaft 21 is connected to the end of the connecting assembly 10 away from the external drive spindle, and the axis of the connecting shaft 21 is coaxially arranged with the axis of the connecting assembly 10. The other end of the connecting shaft 21 is connected to one end of the balancing member 22. The other end of the balancing member 22 is provided with an eccentric hole 221 extending toward one end of the balancing member 22. The axis of the eccentric hole 221 is eccentrically arranged with the axis of the connecting shaft 21. The balancing member 22 is used to ensure the rotational dynamic radial force when the eccentric assembly 20 rotates. For ease of understanding and explanation, the embodiment of the present application defines that the axis of the connecting shaft 21 and the axis of the connecting assembly 10 are both the first axis 211, and the axis of the eccentric hole 221 is the second axis 224. The first axis 211 and the second axis 224 are eccentrically arranged. The bearing member 30 is arranged in the eccentric hole 221. One end of the grinding disc assembly 40 is connected to the bearing member 30, and the grinding disc assembly 40 can rotate relative to the eccentric assembly 20 through the bearing member 30. The bearing member 30 can be a high-speed load-bearing bearing. One end of the buffer assembly 50 is connected to the other end of the grinding disc assembly 40, and the other end of the buffer assembly 50 is used to connect with an external grinding member (not shown). Among them, the shapes of the grinding disc assembly 40 and the buffer assembly 50 are adapted to the shape of the grinding member, and the grinding member can be sandpaper, etc. The grinding member, the buffer assembly 50, the grinding disc assembly 40, the bearing member 30 and the eccentric hole 221 are coaxially arranged.

[0070] When the above eccentric grinding mechanism 100 is in use, the connection component 10 of the eccentric grinding mechanism 100 is connected to an external driving main shaft, and a suitable grinding piece is selected according to the material of the product to be ground and the required grinding cutting force, and the suitable grinding piece is connected to the buffer component 50. The driving main shaft drives the eccentric grinding mechanism 100 to rotate. The connection component 10 and the connecting shaft 21 of the eccentric grinding mechanism 100 rotate coaxially with the driving main shaft. Since the second axis 224 of the eccentric hole 221 is eccentrically arranged with respect to the first axis 211 of the connecting shaft 21, the grinding disc assembly 40, the buffer component 50 and the grinding piece perform eccentric rotation relative to the driving main shaft. The surface of the product is ground by the friction and cutting between the grit on the grinding piece and the product, causing changes in the surface of the product and improving the mechanical properties of the product surface. Among them, since the grinding piece performs eccentric rotation relative to the driving main shaft, and the grinding piece can also rotate self - sufficiently through the bearing component 30 when following the connection component 10 for eccentric rotation, the grinding piece itself also rotates to grind the product surface. The grinding circles formed by grinding can overlap each other, and the grinding piece alternately grinds the product surface, thereby offsetting the grinding dead points. And because the eccentric grinding mechanism 100 is driven by the driving main shaft, the driving main shaft can provide a stable rotational speed and feed for the eccentric grinding mechanism 100, so that the grinding cutting force when the eccentric grinding mechanism 100 drives the grinding piece to grind the product surface is relatively uniform, which is beneficial to improving the grinding marks, grinding tangents and other defects on the product surface, so that the product surface meets the grinding requirements.

[0071] In addition, since the eccentric grinding mechanism 100 is driven by the driving main shaft, the eccentric grinding mechanism 100 can achieve high - speed and high - feed rotation under the driving action of the driving main shaft. The grinding performance of the eccentric grinding mechanism 100 is stable, which is beneficial to improving the grinding efficiency and quality. And the rotational speed and feed of the eccentric grinding mechanism 100 can be adjusted according to the materials of different products and the magnitude of the required grinding cutting force, so as to meet the grinding requirements of different products and improve the versatility of the eccentric grinding mechanism 100; the buffer component 50 buffers the acting force transmitted from the grinding piece, so that the eccentric grinding mechanism 100 realizes flexible grinding of the product.

[0072] In this embodiment, the connection component 10 includes a tool shank 11 and a collet 12. One end of the tool shank 11 is used for adaptively connecting to an external driving main shaft, the other end of the tool shank 11 is adaptively connected to one end of the collet 12, and the other end of the collet 12 is adaptively and tightly connected to the connecting shaft 21. Exemplarily, one end of the connecting shaft 21 is adaptively inserted into the collet 12, and a fastening screw (not shown in the figure) passes through the collet 12 and abuts against the connecting shaft 21, so as to realize the fastening connection between the collet 12 and the connecting shaft 21. Or, one end of the connecting shaft 21 is inserted into the collet 12 by interference fit. In this way, by setting the specific structure of the above - mentioned connection component 10, the connection component 10 realizes the connection with the driving main shaft and the connecting shaft 21 respectively. The structure of the connection component 10 is simple and stable, which is beneficial to reducing costs.

[0073] In this embodiment, the balance member 22 includes a first counterweight 222 and a second counterweight 223 connected to each other. One end of the first counterweight 222 is perpendicularly connected to the connecting shaft 21. The other end of the first counterweight 222 extends in a direction perpendicular to the first axis 211 of the connecting shaft 21 toward the second axis 224 of the eccentric hole 221 and protrudes beyond the second axis 224 of the eccentric hole 221. The axis of the second counterweight 223 is substantially coaxial with the first axis 211 of the connecting shaft 21 and the second counterweight 223 is symmetrically arranged about the axis of the connecting shaft 21. One end of the second counterweight 223 protrudes relatively beyond one end of the first counterweight 222, and the other end of the first counterweight 222 protrudes relatively beyond the other end of the second counterweight 223. The eccentric hole 221 penetrates through the second counterweight 223 and extends to the first counterweight 222. Thus, by setting the specific structure of the balance member 22, the upper and lower centers of rotation of the first counterweight 222 and the second counterweight 223 are reasonably configured to ensure the radial force of the rotation of the eccentric assembly 20 and ensure the balance during the rotation of the eccentric assembly 20. Among them, the connecting shaft 21, the first counterweight 222 and the second counterweight 223 can be integrally formed.

[0074] It can be understood that in other embodiments, the eccentric hole 221 can also be only provided on the second counterweight 223, and can be specifically set according to actual situations.

[0075] In this embodiment, the grinding disc assembly 40 includes a connecting rod 41 and a grinding disc 42. One end of the connecting rod 41 is adaptively connected to the bearing member 30. Specifically, one end of the connecting rod 41 is adaptively connected to the inner ring of the bearing member 30. The other end of the connecting rod 41 is connected to one end of the grinding disc 42, and the other end of the grinding disc 42 is connected to the buffer assembly 50. Thus, by providing the above-mentioned connecting rod 41 and grinding disc 42, the grinding disc assembly 40 realizes the connection with the bearing member 30 and the connection with the buffer assembly 50 respectively.

[0076] It can be understood that in other embodiments, the connecting rod 41 can also penetrate through the grinding disc 42 to be connected to the buffer assembly 50, so that the connecting rod 41 can directly bear the acting force on the grinding member transmitted by the buffer assembly 50, avoiding the acting force on the grinding member being transmitted to the grinding disc 42 and causing the grinding disc 42 to deform, and improving the stability of the grinding disc assembly 40, which can be specifically set according to actual situations.

[0077] In this embodiment, the grinding wheel assembly 40 further includes a seal 43 and a fixing member 44. The seal 43 can be a rubber ring. The seal 43 is sleeved on the connecting rod 41 and located on the side of the eccentric hole 221 facing the grinding wheel 42, that is, the seal 43 is in sealed connection with the eccentric hole 221 and can rotate with the connecting rod 41. The seal 43 abuts against the second counterweight 223 of the balancing member 22 at the same time. The fixing member 44 is located in the eccentric hole 221 and abuts against the side of the connecting rod 41 passing through the bearing member 30. Specifically, the fixing member 44 is connected to the side of the connecting rod 41 passing through the bearing member 30 and abuts against the inner ring of the bearing member 30. The fixing member 44 is used to fix the connecting rod 41 and the bearing member 30, and the fixing member 44 can rotate with the connecting rod 41. In this way, by providing the above-mentioned seal 43, the sealing of the eccentric hole 221 is realized, and external impurities are prevented from entering the eccentric hole 221 and contaminating the bearing member 30. By providing the above-mentioned fixing member 44, the connecting rod 41 and the bearing member 30 are fixed to ensure the rotational balance and stability of the grinding wheel assembly 40.

[0078] In this embodiment, the buffer assembly 50 includes a connected buffer member 51 and a pasting member 52. The buffer member 51 is connected to the grinding wheel 42 of the grinding wheel assembly 40. The buffer member 51 can be a foam member or a rubber member, so that the buffer member 51 has good buffering performance. The pasting member 52 is used to detachably paste an external grinding member. The pasting member 52 can be a magic tape, so that the pasting member 52 can quickly paste and detach the grinding member. In this way, by providing the above-mentioned buffer member 51, the buffer assembly 50 has good buffering performance, so as to buffer the acting force transmitted from the grinding member, so that the eccentric grinding mechanism 100 realizes flexible grinding of the product. By providing the above-mentioned pasting member 52, the buffer assembly 50 can quickly paste and detach the grinding member, which is beneficial to quickly replace the grinding member of the eccentric grinding mechanism 100 and improve the versatility of the eccentric grinding mechanism 100.

[0079] Please refer to Figure 3 , this embodiment of the present application further provides a processing device 1. The processing device 1 is used to process products 2, such as grinding, polishing, drilling, etc. When the processing device 1 grinds the product 2, it is beneficial to eliminate the grinding static points, improve the defects such as grinding marks and grinding tangents on the surface of the product 2, and make the surface of the product 2 meet the grinding requirements. For the convenience of understanding and description, this embodiment of the present application defines an XYZ coordinate system as Figure 3 shown, where the Z-axis direction can be understood as the first direction, the X-axis direction or the Y-axis direction can be understood as the second direction, and correspondingly, the Y-axis direction or the X-axis direction can be understood as the third direction.

[0080] The processing device 1 includes a machine table 200, a loading mechanism 300, a driving spindle 400, and the eccentric grinding mechanism 100 as described in the above embodiments. The machine table 200 is used to install the loading mechanism 300, the driving spindle 400, the eccentric grinding mechanism 100, etc., so that the processing device 1 realizes modular setting. The loading mechanism 300 is arranged on the machine table 200. The loading mechanism 300 is used to load and fix the product 2 to be processed. The loading mechanism 300 is generally a frame structure, and the loading mechanism 300 can have the functions of positioning and fixing the product 2. The driving spindle 400 is arranged on the machine table 200 and above the loading mechanism 300. The tool holder 11 of the connecting component 10 of the eccentric grinding mechanism 100 is connected to the driving spindle 400. The driving spindle 400 is used to drive the eccentric grinding mechanism 100 to rotate to grind the product 2.

[0081] When the above-mentioned processing device 1 is in use, the connecting component 10 of the eccentric grinding mechanism 100 is connected to the driving spindle 400, and a suitable grinding piece is selected according to the material of the product 2 to be ground and the required grinding cutting force, and the suitable grinding piece is connected to the buffer component 50. The product 2 to be ground is placed on the loading mechanism 300. The driving spindle 400 drives the eccentric grinding mechanism 100 to rotate. The connecting component 10 and the connecting shaft 21 of the eccentric grinding mechanism 100 rotate coaxially with the driving spindle 400. Since the second axis 224 of the eccentric hole 221 is eccentrically arranged with respect to the first axis 211 of the connecting shaft 21, the grinding disc assembly 40, the buffer component 50, and the grinding piece rotate eccentrically relative to the driving spindle 400. The surface of the product 2 is ground by the friction and cutting of the gravel on the grinding piece and the product 2, so that the surface of the product 2 changes, and thus the mechanical properties of the surface of the product 2 are improved. Among them, since the grinding piece rotates eccentrically relative to the driving spindle 400, and the grinding piece can also rotate self by means of the bearing member 30 when following the connecting component 10 to rotate eccentrically, the grinding piece itself also rotates to grind the product surface. The grinding piece can make the grinding circles formed by grinding overlap each other, and the grinding piece alternately grinds the surface of the product 2, so as to offset the grinding dead points. And since the eccentric grinding mechanism 100 is driven by the driving spindle 400, the driving spindle 400 can provide a stable rotation speed and feed for the eccentric grinding mechanism 100, so that the grinding cutting force when the eccentric grinding mechanism 100 drives the grinding piece to grind the surface of the product 2 is more uniform, which is beneficial to improving the defects such as grinding marks and grinding tangents on the surface of the product 2, so that the surface of the product 2 meets the grinding requirements.

[0082] In addition, since the eccentric grinding mechanism 100 is driven by the driving main shaft 400, the eccentric grinding mechanism 100 can achieve high-speed and high-feed rotation. The grinding performance of the eccentric grinding mechanism 100 is stable, which is beneficial to improving the grinding efficiency and quality. Moreover, the rotation speed and feed of the eccentric grinding mechanism 100 can be adjusted according to the material of different products 2 and the required grinding cutting force, so as to meet the grinding requirements of different products 2 and improve the versatility of the eccentric grinding mechanism 100. The buffer assembly 50 buffers the acting force transmitted from the grinding piece, enabling the processing device 1 to perform flexible grinding on the product 2.

[0083] In order to grind the entire area of the product 2, in this embodiment, the processing device 1 further includes a first driving mechanism 500 and a second driving mechanism 600. The first driving mechanism 500 is disposed on the machine table 200 and connected to the driving main shaft 400. The first driving mechanism 500 is used to drive the connected driving main shaft 400 and the eccentric grinding mechanism 100 connected to the driving main shaft 400 to approach or move away from the carrying mechanism 300 along the first direction, so that the eccentric grinding mechanism 100 grinds the product 2 or moves away from the ground product 2. The second driving mechanism 600 is disposed on the machine table 200 and connected to the carrying mechanism 300. The second driving mechanism 600 is located below the carrying mechanism 300. The second driving mechanism 600 is used to drive the carrying mechanism 300 to move along the second direction and the third direction. Among them, the first driving mechanism 500 can be a single-axis linear module, and the second driving mechanism 600 can be a two-axis linear module. The two-axis linear module can be understood as two linear modules connected perpendicularly to each other, which will not be elaborated in this application embodiment. In this way, by setting the above-mentioned first driving mechanism 500 and second driving mechanism 600, through the cooperation of the first driving mechanism 500 and the second driving mechanism 600, the eccentric grinding mechanism 100 grinds the entire area of the product 2.

[0084] It can be understood that in other embodiments, the second driving mechanism 600 can also be a single-axis linear module, and the second driving mechanism 600 drives the carrying mechanism 300 to move along the second direction or the third direction, which can be specifically set according to the actual situation.

[0085] In order to improve the versatility of the processing equipment 1, in this embodiment, the processing equipment 1 further includes a tool magazine 700, which is used to accommodate a variety of tools of different specifications (not shown), and the tools are used to process the product 2, such as punching, cutting, etc. The tool magazine 700 is located on one side of the driving spindle 400 and above the bearing mechanism 300. Specifically, the tool magazine 700 is located on the side of the driving spindle 400 away from the first driving mechanism 500. The tool magazine 700 includes a tool compartment 701, a connecting member 702, an elastic member 703 and a water spray pipe 704. The tool compartment 701 is movably connected to the driving spindle 400. The tool compartment 701 is used to accommodate multiple tools. Exemplarily, the tool compartment 701 is movably connected to the driving spindle 400 through a rod-shaped object 705, that is, the tool compartment 701 can be relatively close to or away from the driving spindle 400 through the rod-shaped object 705, wherein the rod-shaped object 705 can be a telescopic rod. One end of the connecting member 702 is rotatably connected to the tool chamber 701, and the other end of the connecting member 702 is movably connected to the driving spindle 400 along a preset track. When the tool chamber 701 approaches or moves away from the driving spindle 400, the tool chamber 701 and the connecting member 702 rotate relative to each other and the connecting member 702 moves along the preset track on the driving spindle 400, so that the tool chamber 701 can approach or move away from the driving spindle 400. The two ends of the elastic member 703 are respectively connected to the tool chamber 701 and the driving spindle 400, and the elastic member 703 is located above the connecting member 702. There are two connecting members 702 and two elastic members 703, and they are respectively located on opposite sides of the driving spindle 400 to ensure the balance of the tool chamber 701 when it moves. The water spray pipe 704 is arranged on the side of the tool chamber 701 facing the driving spindle 400. The water spray pipe 704 is used to connect the water source and spray water to the product 2 to cool the product 2 or wash away the debris on the product 2. Among them, the exemplary implementation of the other end of the connecting member 702 moving along the preset track on the driving spindle 400 can be roughly as follows: a pulley is provided at the other end of the connecting member 702, and a slideway is provided along the preset track on the driving spindle 400, and the pulley is slidably connected with the slideway, so that the other end of the connecting member 702 moves along the preset track on the driving spindle 400. It can be understood that the other end of the connecting member 702 can also be moved along the preset track on the driving spindle 400 through other implementations, and the embodiments of the present application will not be repeated here.

[0086] Thus, when the processing device 1 needs to process the product 2, such as drilling, an external manipulator (not shown in the figure) makes the tool magazine 701 approach the driving main shaft 400 in cooperation with the rod-shaped object 705 and the connecting member 702 by abutting against the tool magazine 701. And compress the elastic member 703 to make the elastic member 703 generate elastic force. The external manipulator takes out the tool to be used from the tool magazine 701. When the external manipulator takes out the tool, it releases the tool magazine 701. The tool magazine 701 elastically restores under the elastic force of the elastic member 703. The external manipulator drives the tool to drill the product 2. When the external manipulator drives the tool to drill the product 2, the water spray pipe 704 sprays water on the product 2 to cool the product 2 and wash away the debris on the product 2, ensuring the cleanliness of the product 2. When the external manipulator drives the tool to drill the product 2, the driving main shaft 400 can drive the eccentric grinding mechanism 100 to grind the surface of the product 2 so that the surface of the product 2 meets the processing and grinding requirements, thereby improving the versatility of the processing device 1.
