[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The features of the terms "first" and "second" in the specification and claims of the utility model may explicitly or implicitly include one or more of the features. In the description of the utility model, unless otherwise specified, the meaning of "plurality" is two or more.

[0028] Combine the following Figure 1-Figure 4 The utility model is described as a polishing device for large-sized parts.

[0029] like Figure 2 As shown, in an embodiment of the utility model, the polishing device for large-sized parts includes: a turntable 1, a ring polishing spacer 2 and a fixed tool 3. The ring polishing spacer 2 is arranged on the turntable 1, and the fixed tool 3 is arranged in the ring polishing spacer 2. The fixed tool 3 is used to fix the part 100 to be polished. The turntable 1 has a polishing surface, and the polishing surface is in contact with the surface to be processed of the part 100. The fixed tool 3 includes: a locking assembly 32 and a plurality of matching discs 31, and the plurality of matching discs 31 are used to be arranged on opposite sides of the part 100. The locking assembly 32 is sleeved on the outside of the plurality of matching discs 31 so that the matching discs 31 clamp the part 100.

[0030] Specifically, if Figure 1 As shown, in the embodiment of the present invention, the length and width of the part 100 are equal. In this embodiment, the large-size part refers to a part with a length-to-thickness ratio greater than 7. Such a part 100 has a large difference in length and thickness. Figure 1 When the planes S2, S3, the plane opposite to S2 and the plane opposite to S3 shown in the figure are polished, the part 100 is not stable and is very likely to shake, causing the part 100 to collide with the ring polishing spacer 2 and produce microscopic deformation. Optionally, in the embodiment of the utility model, the size of the part 100 is 600mm×600mm×80mm.

[0031] In the embodiment of the utility model, the number of the matching discs 31 is a pair. The pair of matching discs 31 are respectively fitted with the surface S1 of the part 100 and the surface opposite to S1, and the bottom surface of the matching disc 31 is fitted with the polishing surface. The locking assembly 32 is sleeved on the outside of the pair of matching discs 31 so that the pair of matching discs 31 clamps the part 100, thereby improving the stability of the part 100 after being placed. The bottom surface of the part 100 is fitted with the polishing surface of the turntable 1, and when the turntable 1 rotates, the bottom surface of the part 100 can be polished.

[0032] In this embodiment, during the rotation of the turntable 1, the locking assembly 32 and the matching disk 31 clamp and tighten the part 100, and the part 100 is not easy to shake. In addition, the locking assembly 32 is provided on the outside of the part 100. Even if the whole formed by the locking assembly 32, the matching disk 31 and the part 100 after being fixed moves in the ring-shaped spacer 2, it is the locking assembly 32 that collides with the ring-shaped spacer 2, and the part 100 does not contact the ring-shaped spacer 2, thereby avoiding deformation of the part 100 after the collision.

[0033] Furthermore, the size of the locking assembly 32 can be set according to the inner diameter of the ring-shaped spacer 2. The size of the locking assembly 32 is designed to be not much different from the inner diameter of the ring-shaped spacer 2 to prevent the locking assembly 32 from moving significantly during the rotation of the turntable 1, thereby reducing the collision force between the ring-shaped spacer 2 and the locking assembly 32.

[0034] The polishing device for large-sized parts provided by the embodiment of the utility model increases the contact area between the part and the turntable and improves the stability of the part during polishing by arranging multiple matching discs and locking assemblies. The matching discs are fixed on both sides of the part, thereby reducing the degree of warping when the part collides with the polishing ring and ensuring the surface shape and smoothness of the part.

[0035] Furthermore, in the embodiment of the present invention, the length of each matching plate 31 is greater than the width of the surface in contact with it.

[0036] Specifically, if Figure 2 As shown, a pair of matching plates 31 are respectively fitted with the surface S1 of the part 100 and the surface opposite to S1. In this embodiment, the material of the matching plates 31 is the same as that of the part 100, so the matching plates 31 can be directly fitted with the part 100. When the material of the locking assembly 32 is the same as that of the part 100, the locking assembly 32 can also be fitted with the surface S2 of the part 100 and the surface opposite to S2.

[0037] In this embodiment, the locking assembly 32 is made of metal, and the part 100 is an optical device. When the locking assembly 32 directly contacts the surface of the part 100, the surface of the part 100 may be scratched by the locking assembly 32. Therefore, in this embodiment, the length of the matching plate 31 is greater than the length of the part 100, so that when the locking assembly 32 is sleeved on the outside of the matching plate 31, there is a certain gap between the locking assembly 32 and the part 100 to prevent the surface of the part 100 from being scratched. Optionally, in the embodiment of the utility model, the gap is 2 mm.

[0038] like Figure 3As shown, in the embodiment of the utility model, the locking assembly 32 includes a plurality of fixing members and a plurality of first connecting members 323. The plurality of fixing members are sequentially connected end to end through the first connecting members 323 to form a frame, which is sleeved on the outside of the plurality of matching plates 31, wherein the two ends of at least one fixing member are adjustably connected to the other fixing members.

[0039] Specifically, in this embodiment, the number of fixing members is 4. Optionally, three fixing members are sequentially connected end to end to form a rectangular frame structure, the rectangular frame structure is sleeved on the outside of the matching plate 31, and then the last fixing member is connected to the rectangular frame structure. In this embodiment, the adjustable connection means that the position of the connection between the fixing member and the rectangular frame structure is adjustable, so as to clamp the matching plate 31 and the part 100 according to the actual size of the matching plate 31.

[0040] Optionally, the connections of the four fixing members may all be connected in an adjustable manner.

[0041] Optionally, there are multiple ways of adjustable connection, such as the connection hole is in the shape of a strip hole, so that the position of the first connecting member 323 in the strip hole can be adjusted according to the actual size of the matching disk 31, thereby clamping the matching disk 31 and the part 100; for example, multiple holes can be set on the fixing member, so that the first connecting member 323 can be inserted into the corresponding holes according to the actual size of the matching disk 31.

[0042] like Figure 3 As shown, in an embodiment of the utility model, the plurality of fixing members include: a pair of first fixing members 321 and a pair of second fixing members 322, the pair of first fixing members 321 are arranged in parallel, the pair of second fixing members 322 are arranged in parallel, the second fixing members 322 are perpendicular to the first fixing members 321, and the two ends of each first fixing member 321 are adjustably connected to the two ends of the second fixing member 322 respectively.

[0043] Specifically, in this embodiment, the first fixing member 321 is fitted with the end surface on the same side of a pair of matching disks 31, and the second fixing member 322 is fitted with the surface of the matching disk 31. The connection between each first fixing member 321 and the second fixing member 322 adopts an adjustable connection to adjust the distance between the pair of second fixing members 322 according to the actual size of the matching disk 31, thereby clamping the part 100.

[0044] like Figure 3As shown, in the embodiment of the utility model, first holes 3211 are respectively provided at both ends of the first fixing member 321, second holes 3221 are respectively provided at both ends of the second fixing member 322, and the first connecting member 323 is penetrated through the first hole 3211 and the second hole 3221 to connect the first fixing member 321 and the second fixing member 322, wherein the first hole 3211 is a strip hole, and the diameter of the first connecting member 323 is smaller than the length of the first hole 3211, so that the first hole 3211 has an adjustable length, and then the connection position of the second fixing member 322 and the first fixing member 321 can be adjusted according to the actual size of the matching plate 31, thereby clamping the part 100.

[0045] Further, the second fixing member 322 includes: a first fixing portion 3222 and a pair of second fixing portions 3223, the pair of second fixing portions 3223 are respectively arranged at both ends of the first fixing portion 3222 and vertically connected to the first fixing portion 3222, and each second fixing portion 3223 is provided with a second hole 3221. In this embodiment, the second hole 3221 can be a circular hole or a bar hole.

[0046] like Figure 3 and Figure 4 As shown, in an embodiment of the utility model, the fixing tool 3 also includes a pair of buffer components 33, which are arranged opposite to each other, one end of each buffer component 33 is connected to the locking component 32, and the other end of each buffer component 33 is used to flexibly abut against the surface of the part 100.

[0047] Specifically, in this embodiment, the matching plate 31 is used to fix the lower part of the part 100, and the buffer assembly 33 is used to fix the upper part of the part 100, so that the part 100 will not shake during the polishing process, thereby improving the accuracy of polishing.

[0048] Furthermore, each buffer assembly 33 includes: a second connecting member 331, an adjusting member 332 and a buffer sheet 333. The two ends of the second connecting member 331 are respectively connected to the locking assembly 32 and the adjusting member 332. The adjusting member 332 is connected to the buffer sheet 333. The buffer sheet 333 has a flexible surface, and the flexible surface is used to abut against the part 100. The adjusting member 332 is used to adjust the distance between the second connecting member 331 and the buffer sheet 333 so that the buffer sheet 333 can abut against the part 100.

[0049] Specifically, in this embodiment, the buffer sheet 333 can be a flexible sheet or a rigid sheet. When the buffer sheet 333 is a rigid sheet, a flexible material is provided on the surface that contacts the part 100 to prevent the surface of the part 100 from being scratched.

[0050] Furthermore, in the embodiment of the present invention, the adjusting member 332 is threadedly connected to the second connecting member 331 , so that the distance between the second connecting member 331 and the part 100 can be adjusted by screwing in or out, so that the buffer sheet 333 abuts against the part 100 .

[0051] Furthermore, the main indicators for measuring the polishing quality of the part 100 are surface shape, parallelism and verticality. After the part 100 is polished for a period of time, the surface shape is observed, and the fixed tooling 3 can also be disassembled to detect the surface shape, parallelism and verticality. When it is found that the parallelism or verticality of the polished surface is poor, the processing position can be adjusted by adding a counterweight block.

[0052] In the embodiment of the present utility model, the fixing device 3 further comprises a counterweight block, and the counterweight block is arranged on a matching plate 31 .

[0053] Specifically, assuming that the plane S4 opposite to S3 is polished, the parallelism between S4 and S3 is checked after polishing for a period of time, and it is found that the distance between the right side of S4 and S3 is smaller than the distance between the left side of S4 and S3, then the counterweight block is placed on the counterweight plate 31 on the right side to tilt the part 100 to the left so as to polish the left side of S4.

[0054] The polishing device for large-sized parts provided by the embodiment of the utility model not only enhances the stability of the parts during polishing by setting a fixed tool, but also can adjust the polishing position of the parts by using a counterweight block, thereby achieving fine adjustment of the parallelism and verticality of the parts and improving the surface quality of the parts after polishing.
