Description

Technical Field

[0001] This utility model relates to the field of polishing fixture technology, and in particular to a fixture for polishing crystal planes. Background Technology

[0002] Polishing fixtures are tools used to fix workpieces during the polishing process, ensuring that the workpieces maintain a stable position and correct posture during processing. Different types of polishing fixtures are suitable for different workpieces and processing scenarios. Currently, silicon carbide is widely used in industrial, defense, scientific research, and civilian fields. In the crystal processing process, fixtures and tooling are often required for clamping and positioning.

[0003] In the prior art, when it is necessary to polish a round crystal, the crystal needs to be clamped by a clamping plate. However, in order to clamp the crystal firmly, multiple clamping plates are often used to clamp or release it. Therefore, each clamping plate needs to be controlled to clamp or release it individually, which takes a long time to operate the clamping plates to clamp or release the crystal, thus wasting time. In addition, if the clamping force of one clamping plate is different from that of the other clamping plates during the clamping process, it is easy to cause the crystal clamping position to shift, affecting the processing accuracy. Summary of the Invention

[0004] This utility model provides a fixture for crystal plane polishing, which facilitates quick and convenient operation of all clamping plates to clamp and position the crystal, and also helps to prevent the crystal clamping position from shifting.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A fixture for polishing crystal planes includes a mounting frame and several clamping plates, all of which are disposed within the mounting frame;

[0007] A support plate is fixed inside the mounting frame. At least two return springs are connected between the clamping plate and the mounting frame. A pressure rod is fixed on the outside of the clamping plate. The pressure rod slides through the mounting frame. A triangular pressure block is fixed at the outer end of the pressure rod. A push ball is provided on one side of the inclined surface of the pressure block. A guide ring is provided outside the mounting frame. The push ball is fixed to the inner wall of the guide ring.

[0008] Guide plates are fixed at both ends of the mounting bracket, and several oblique teeth are connected to the outer wall of the guide ring. Limiting and locking components are provided at both ends of the mounting bracket.

[0009] Furthermore, buffer pads are connected to the inner sides of the clamps.

[0010] Furthermore, operating levers are fixed around the outer wall of the guide ring.

[0011] Furthermore, the guide plate has a through opening running vertically through it, and the guide ring passes through the through opening.

[0012] Furthermore, a slider is fixed inside the opening, and grooves are opened on both the left and right sides of the guide ring, with the slider slidably connected to the grooves.

[0013] Furthermore, each of the limiting locking components includes a limiting block, a limiting rod, a handle, and at least two return springs. The limiting block is engaged between any two adjacent oblique teeth. The limiting rod is fixed to the outside of the limiting block and slides through the guide plate. The handle is fixed to the outer end of the limiting rod. Each of the return springs is connected between the handle and the guide plate.

[0014] Furthermore, the inner side of the limiting block is inclined, and the inclined surface of the limiting block matches the inclined surface of the inclined tooth.

[0015] The beneficial effects of this utility model are:

[0016] By setting multiple clamping plates, and then rotating the guide ring counterclockwise, all the push balls rotate together. The push balls press against the pressure block, pressure rod, and clamping plates, which facilitates the simultaneous approach and clamping of all the clamping plates to the crystal. After the guide ring rotates and resets, it helps to move the push balls away from the pressure block. Combined with the rebound force of the reset spring, it helps to reset all the clamping plates, thus facilitating the quick and convenient release of the crystal. In summary, there is no need to operate each clamping plate individually to clamp or release the crystal, which not only saves the time of clamping or releasing operations, but also avoids the crystal clamping position from shifting, and effectively ensures the processing accuracy after the crystal is clamped.

[0017] By setting a limit locking component, the limit block is locked between two adjacent inclined teeth, which helps to prevent the guide ring from rotating and resetting, and effectively ensures the firmness of the clamping plate in clamping the crystal. Attached Figure Description

Detailed Implementation

[0024] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0025] like Figure 1-3 As shown, in this embodiment, a mounting frame 1 and several clamping plates 2 are included. The clamping plates 2 are all located inside the mounting frame 1. A support plate 17 is fixed inside the mounting frame 1. At least two return springs 3 are connected between the clamping plates 2 and the mounting frame 1. A pressure rod 4 is fixed to the outside of the clamping plates 2. The pressure rod 4 slides through the mounting frame 1. A triangular pressure block 5 is fixed to the outer end of the pressure rod 4. A push ball 6 is provided on one side of the inclined surface of the pressure block 5. A guide ring 8 is provided outside the mounting frame 1. The push ball 6 is fixed to the inner wall of the guide ring 8.

[0026] When the crystal is clamped by the clamp, the crystal is placed on the support plate 17 and positioned inside all the clamping plates 2. Then, by rotating the guide ring 8 counterclockwise, all the push balls 6 are rotated together. The push balls 6 push the pressure block 5, pressure rod 4 and clamping plate 2 inward through the inclined surface of the pressure block 5, which facilitates the simultaneous approach and clamping of all the clamping plates 2 until the clamping plates 2 clamp the crystal, thus saving the operation time of clamping the crystal.

[0027] like Figure 1 As shown in this embodiment, operating rods 10 are fixed around the outer wall of the guide ring 8.

[0028] When the guide ring 8 is rotated, the operating lever 10 drives the guide ring 8 to rotate counterclockwise, making the rotation of the guide ring 8 more effortless and convenient.

[0029] like Figure 4 As shown in this embodiment, the guide plate 7 has a through opening 16 extending vertically, the guide ring 8 passes through the through opening 16, a slider 18 is fixed inside the through opening 16, and the guide ring 8 has grooves 19 on both the left and right sides, and the slider 18 is slidably connected to the grooves 19.

[0030] When the guide ring 8 rotates counterclockwise, the slider 18 slides along the groove 19, which helps to ensure the smoothness of the guide ring 8 during rotation.

[0031] like Figure 1 , 4As shown, in this embodiment, guide plates 7 are fixed to both the left and right ends of the mounting frame 1, and several oblique teeth 11 are connected to the outer wall of the guide ring 8. Limiting and locking components are provided at both the left and right ends of the mounting frame 1. Each limiting and locking component includes a limiting block 13, a limiting rod 12, a handle 14, and at least two return springs 15. The limiting block 13 is engaged between any two adjacent oblique teeth 11. The limiting rod 12 is fixed to the outside of the limiting block 13 and slides through the guide plate 7. The handle 14 is fixed to the outer end of the limiting rod 12. Each return spring 15 is connected between the handle 14 and the guide plate 7. The inner side of the limiting block 13 is inclined, and the inclined surface of the limiting block 13 matches the inclined surface of the oblique teeth 11.

[0032] When the guide ring 8 rotates counterclockwise, due to the elastic force of the return spring 15, the inclined teeth 11 will push the limiting block 13, the limiting rod 12 and the handle 14 outward. The handle 14 will stretch the return spring 15 until the clamping plate 2 clamps the crystal. At this time, the return spring 15 will drive the handle 14, the limiting rod 12 and the limiting block 13 to reset through the rebound force, so that the limiting block 13 is locked into the two adjacent inclined teeth 11, which helps to prevent the guide ring 8 from rotating and resetting, and effectively ensures the firmness of the clamping plate 2 clamping the crystal.

[0033] like Figure 1 , 3 As shown in this embodiment, buffer pads 9 are connected to the inner sides of the clamping plates 2.

[0034] By setting a buffer pad 9 on the inside of the clamping plate 2, the crystal is buffered by the buffer pad 9 when the clamping plate 2 clamps the crystal, thus avoiding damage to the crystal.

[0035] like Figure 1 , 4 As shown, in this embodiment, the limiting block 13 is engaged between any two adjacent oblique teeth 11, the limiting rod 12 is fixed to the outside of the limiting block 13, and the limiting rod 12 slides through the guide plate 7, the handle 14 is fixed to the outer end of the limiting rod 12, and the return springs 15 are all connected between the handle 14 and the guide plate 7.

[0036] When the crystal needs to be released, the limit rod 12 and the limit block 13 are pulled outward by the handle 14. The limit block 13 moves out between two adjacent teeth. The guide ring 8 is rotated clockwise and the push ball 6 is moved away from the pressure block 5. Then, the return force of the reset spring 3 will move the pressure block 5, the pressure rod 4 and the clamping plate 2 away from the crystal until the clamping plate 2 no longer clamps the crystal, thus making it easy to release the crystal. In summary, there is no need to operate the clamping plate 2 to clamp or release the crystal one by one. This not only saves the time of clamping or releasing operations, but also avoids the situation of the crystal clamping position being offset, and effectively ensures the processing accuracy after the crystal is clamped.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, other implementations are also included. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
