[0010] Furthermore, the retainer is a circular structural plate, the outer peripheral edge of the retainer is toothed, and the outer diameter of the retainer is larger than the outer diameter of the upper grinding disk and larger than the outer diameter of the lower grinding disk.

[0011] Furthermore, the second driving device includes a rotation drive module and multiple guide wheel sets. The rotation drive module and the multiple guide wheel sets are arranged around the cage and installed at different positions on the bracket. The rotation drive module drives the cage to rotate, and the multiple guide wheel sets are used to fix the rotation center of the cage.

[0012] Furthermore, the self-rotating drive module includes: a mounting base, a self-rotating drive motor, and a rotating wheel. The mounting base is mounted on the bracket, the self-rotating drive motor is mounted on the mounting base, the rotating wheel is connected to the self-rotating drive motor in a transmission manner, and the rotating wheel engages with the cage.

[0013] Furthermore, the guide wheel assembly includes a guide wheel and a fixed seat, the fixed seat is mounted on the bracket, the guide wheel is mounted on the fixed seat, and the guide wheel engages with the cage.

[0014] Furthermore, the number of guide wheel sets is four, wherein two guide wheel sets form a group, and the two groups of guide wheel sets are respectively installed on opposite sides of the bracket.

[0016] Furthermore, both the first drive module and the second drive module include: a translation drive motor, a translation guide rail, a sliding member, and a fixing member; the translation guide rail is mounted on the frame, the translation drive motor is mounted on the translation guide rail, the sliding member is slidably connected to the translation guide rail and drively connected to the translation drive motor, the sliding member of the first drive module is fixedly connected to the bracket through the fixing member, and the sliding member of the second drive module is fixedly connected to the bracket through the fixing member.

[0017] Furthermore, the frame includes: a worktable, a top frame, and two supports; the two supports are symmetrically installed on the worktable, and the two ends of the top frame are respectively fixedly connected to the top ends of the two supports, and the bracket is installed on the two supports through the first driving device.

[0034] 5. Products. Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 6 As shown, this utility model provides a double-sided grinding and polishing equipment for large-size products, comprising:

[0037] Rack 1;

[0038] The top grinding mechanism 2 includes: an upper grinding disc 21 for grinding the upper surface of the product 5;

[0039] The bottom grinding mechanism 3 includes: a lower grinding disc 31 for grinding the lower surface of the product 5;

[0040] The towing mechanism 4 includes: a bracket 41, a retainer 42, a first drive device 43, and a second drive device 44; the bracket 41 is mounted on the frame 1 via the first drive device 43, which drives the bracket 41 to move horizontally; the second drive device 44 is mounted on the bracket 41; the retainer 42 is mounted on the second drive device 44, which drives the retainer 42 to rotate; the retainer 42 has a cavity with the same shape and size as the product 5 for loading the product 5.

[0041] The lower grinding disc 31 serves as both a tool disc and a support disc for the product 5. During processing, the product 5 is placed in the cavity of the retainer 42, thereby securing it on all sides. Simultaneously, the lower surface of the product 5 contacts the lower grinding disc 31, which supports the product 5. The upper grinding disc 21 moves downward under the drive of the top grinding mechanism 2, making contact with and pressing against the upper surface of the product 5. After the upper grinding disc 21 and the lower grinding disc 31 press the product 5 together, the top grinding mechanism 2, the bottom grinding mechanism 3, and the second drive device 44 work, thereby causing the product 5 inside the retainer 42 to rotate. This creates relative sliding between the surface of the product 5 and the upper and lower disc surfaces, achieving the removal of material from the surface of the product 5.

[0042] Meanwhile, since the retainer 42 is mounted on the product 5 bracket 41 via the second drive device 44, during processing, the first drive device 43 can drive the bracket 41 to move horizontally in one direction, thereby driving the retainer 42 and the product 5 to move horizontally. Thus, when dealing with large-sized products 5, the drag mechanism 4 of the large-sized product double-sided grinding and polishing equipment of this application achieves consistency in material removal at different positions on the surface through rotation and horizontal movement, without increasing the size and manufacturing difficulty of the large-sized product double-sided grinding and polishing equipment, and without decreasing the processing accuracy.

[0043] Furthermore, such as Figure 3 As shown, the retainer 42 is a circular structural plate, and the outer peripheral edge of the retainer 42 is set in a tooth shape. The outer diameter of the retainer 42 is larger than the outer diameter of the upper grinding disk 21 and larger than the outer diameter of the lower grinding disk 31.

[0044] It should be noted that the tooth shape can be a pin tooth, gear tooth, or other similar type; in this embodiment, a pin tooth is used.

[0045] Furthermore, such as Figure 4 As shown, the second drive device 44 includes a rotation drive module 441 and multiple guide wheel sets 442. The rotation drive module 441 and multiple guide wheel sets 442 are arranged around the retainer 42 and installed at different positions on the bracket 41. The rotation drive module 441 drives the retainer 42 to rotate, and the multiple guide wheel sets 442 are used to fix the rotation center of the retainer 42.

[0046] During the processing, the first drive unit 43 drives the bracket 41 to translate. Therefore, to prevent the self-rotating drive module 441 from contacting the upper and lower grinding discs during translation and affecting the grinding process, the outer diameter of the retainer 42 must be larger than the outer diameter of the upper grinding disc 21 and the outer diameter of the lower grinding disc 31. This ensures that the self-rotating drive module 441 avoids contact with the upper and lower grinding discs during the translation of the bracket 41. Multiple guide wheel sets 442 provide the rotation center (radial limit) of the retainer 42, which transmits thrust when the retainer 42 moves.

[0047] In addition, the cage 42 is provided with multiple weight-reducing holes, which are used to reduce the weight of the cage 42, thereby reducing the energy consumption of the first drive device 43 and the second drive device 44, while reducing the load on the bracket 41, extending the service life of the equipment, and allowing polishing fluid to flow.

[0048] Furthermore, such as Figure 4 As shown, the self-rotating drive module 441 includes: a mounting base 4411, a self-rotating drive motor 4412, and a rotating wheel 4413. The mounting base 4411 is mounted on the bracket 41, the self-rotating drive motor 4412 is mounted on the mounting base 4411, the rotating wheel 4413 is connected to the self-rotating drive motor 4412 in a transmission connection, and the rotating wheel 4413 is engaged with the retainer 42.

[0049] During the processing, the self-rotating drive motor 4412 drives the rotating wheel 4413 to rotate. Since the rotating wheel 4413 meshes with the cage 42, it can drive the cage 42 to rotate, forming relative sliding between the surface of the product 5 and the upper and lower discs, thereby removing the material from the surface of the product 5. At the same time, the cooperation with the bracket 41 and the first drive device 43 ensures the grinding consistency of the product 5.

[0050] Furthermore, such as Figure 4 As shown, the guide wheel assembly 442 includes a guide wheel 4421 and a fixed seat 4422. The fixed seat 4422 is mounted on the bracket 41, and the guide wheel 4421 is mounted on the fixed seat 4422. The guide wheel 4421 engages with the retainer 42.

[0051] Furthermore, such as Figure 4 As shown, there are four guide wheel sets 442, with two guide wheel sets 442 forming one group. The two groups of guide wheel sets 442 are respectively installed on opposite sides of the bracket 41. The two groups of guide wheel sets 442 are respectively installed on opposite sides of the bracket 41, thereby radially limiting the cage 42.

[0052] Furthermore, such as Figure 3As shown, the first drive device 43 includes a first drive module 431 and a second drive module 432. The first drive module 431 and the second drive module 432 are mounted on the frame 1. The first drive module 431 and the second drive module 432 are respectively connected to opposite sides of the bracket 41. The first drive module 431 and the second drive module 432 cooperate to realize the horizontal movement of the bracket 41.

[0053] The first drive module 431 and the second drive module 432 are respectively connected to opposite sides of the bracket 41, thereby enabling the bracket 41 to move horizontally in the radial direction.

[0054] Furthermore, such as Figure 3 As shown, both the first drive module 431 and the second drive module 432 include: a translation drive motor 4311, a translation guide rail 4312, a sliding member 4313, and a fixing member 4314; the translation guide rail 4312 is mounted on the frame 1, the translation drive motor 4311 is mounted on the translation guide rail 4312, the sliding member 4313 is slidably connected to the translation guide rail 4312 and is drively connected to the translation drive motor 4311, the sliding member 4313 of the first drive module 431 is fixedly connected to the bracket 41 through the fixing member 4314, and the sliding member 4313 of the second drive module 432 is fixedly connected to the bracket 41 through the fixing member 4314.

[0055] The translation drive motor 4311 can drive the sliding member 4313 to slide on the translation guide rail 4312. The sliding member 4313 of the first drive module 431 is fixedly connected to the bracket 41 through the fixing member 4314, and the sliding member 4313 of the second drive module 432 is fixedly connected to the bracket 41 through the fixing member 4314. Therefore, under the drive of the translation drive motor 4311, the bracket 41 can achieve translation, thereby ensuring the grinding consistency of product 5.

[0056] Furthermore, such as Figure 1 and Figure 2 As shown, the frame 1 includes: a workbench 11, a top frame 12 and two supports 13; the two supports 13 are symmetrically installed on the workbench 11, and the two ends of the top frame 12 are fixedly connected to the top ends of the two supports 13 respectively. The bracket 41 is installed on the two supports 13 through the first drive device 43.

[0057] Furthermore, such as Figure 5 and Figure 6 As shown, the top grinding mechanism 2 also includes: a lifting device 22 and an upper grinding device 23. The lifting device 22 is installed on the top frame 12, the upper grinding device 23 is installed on the lifting device 22, and the upper grinding disc 21 is installed on the upper grinding device 23. The upper grinding device 23 is used to drive the upper grinding device 23 to lift and lower, and the upper grinding device 23 is used to drive the upper grinding disc 21 to grind and polish the upper surface of the product 5.

[0058] The bottom grinding mechanism 3 also includes a support frame 32 and a lower grinding device 33. The support frame 32 is installed on the worktable 11, the lower grinding device 33 is installed on the support frame 32, and the lower grinding disc 31 is installed on the lower grinding device 33. The lower grinding device 33 is used to drive the lower grinding disc 31 to grind and polish the lower surface of the product 5.

[0059] The lifting device 22 can drive the upper grinding device 23 to move up and down, so that the upper grinding disc 21 installed on the upper grinding device 23 and the lower grinding disc 31 installed on the lower grinding device 33 cooperate to apply pressure to the product 5, ensuring the grinding and polishing effect of the product 5.
