Description

Technical Field

[0002] In the manufacturing process of the split copper mirror of the optical shutter, it is crucial to ensure the mirror processing accuracy. As the application scope of optical devices continues to expand, the quality requirements for the mirror surface are getting higher and higher. The split copper mirror of the optical shutter usually includes a working part and a special-shaped connecting part. This complex structure makes its processing technology more complicated. High-quality mirror surface not only directly affects the performance of the final product, but also affects the stability and reliability of the entire optical system.

[0003] In the existing technology, in order to perform mirror processing on the special-shaped light gate split copper mirror, manual operation or simple clamps are often used to fix the special-shaped connecting parts of the light gate split copper mirror.

[0025] Reference Figure 1 The positioning block 2 is made of high-strength alloy steel, and its surface is precisely ground to ensure that it perfectly matches the special-shaped connection of the split copper mirror of the optical shutter. The shape and size of the positioning groove 21 are customized according to the special-shaped connection of the specific split copper mirror of the optical shutter to achieve the best fixing effect. The positioning groove 21 can be a V-shaped groove, a U-shaped groove, or other shapes suitable for a specific special-shaped connection.

[0026] Reference Figure 1 The receiving groove 22 is rectangular or circular, and is adjusted according to the shape and size of the special-shaped connection part of the split copper mirror of the light gate to be processed. The pressure strip 3 is made of stainless steel, and the length and width can be selected according to the actual situation to adapt to the split copper mirrors of different specifications, ensuring that the pressure strip 3 can firmly press the special-shaped connection part of the split copper mirror of the light gate.

[0027] Reference Figure 2 , 3 The fixing mechanism includes a mounting seat 12, an insertion rod 13 and a driving assembly. The mounting seat 12 is fixed on the base 1 by welding, and a mounting groove 121 adapted to the positioning block 2 is provided at the top of the mounting seat 12, and a plurality of through holes 122 connected to the mounting groove 121 are provided on the side wall of the mounting seat 12, and each through hole 122 is evenly spaced along the circumference of the mounting seat 12, and an insertion rod 13 is slidably penetrated in each through hole 122, and a plurality of insertion holes 23 for inserting the insertion rod 13 are provided on the side wall of the positioning block 2, and the insertion holes 23 correspond to the insertion rod 13 one by one.

[0028] Reference Figure 2 , 3The driving assembly is used to drive each of the plug rods 13 to slide simultaneously in a direction of approaching or moving away from each other. Specifically, the driving assembly includes a driving ring 14 and a connecting rod 15. The driving ring 14 is rotatably sleeved on the mounting seat 12. The mounting seat 12 is provided with a plurality of openings 123. The openings 123 correspond to the through holes 122 one by one and are connected to the corresponding through holes 122. A plurality of connecting rods 15 are provided and correspond to the plug rods 13 one by one. The connecting rods 15 are arranged in the corresponding openings 123. One end of the connecting rod 15 is hinged to the inner side wall of the driving ring 14. The other end of the connecting rod 15 is hinged to the corresponding plug rod 13. Articulated; by placing the positioning block 2 in the mounting groove 121 of the mounting seat 12, rotating the drive ring 14 clockwise, the drive ring 14 drives the corresponding plug rods 13 to slide through each connecting rod 15, so that each plug rod 13 shrinks inward at the same time and is inserted into the corresponding plug hole 23 on the positioning block 2, and the positioning block 2 can be fixed in the mounting groove 121 of the mounting seat 12; when the drive ring 14 rotates counterclockwise, on the contrary, each plug rod 13 extends outward at the same time, thereby releasing the positioning block 2. Further, by setting a plurality of plug rods 13 and inserting them into the corresponding plug holes 23 on the positioning block 2, a more stable installation and fixation of the positioning block 2 is achieved, and the positioning block 2 is prevented from loosening or shaking during the processing process, thereby ensuring the processing quality of the mirror surface of the split copper mirror of the optical gate.

[0029] Reference Figure 1 , 3 The side wall of the mounting groove 121 is fixedly provided with a guide bar 124, and the side wall of the positioning block 2 is provided with a guide groove 24 for matching with the guide bar 124. Through the setting of the guide bar 124 and the guide groove 24, the positioning block 2 can be accurately aligned along the guide bar 124 and smoothly inserted into the mounting groove 121 during the installation process. When the positioning block 2 is fully inserted into the mounting groove 121, the through hole 122 on the mounting seat 12 corresponds to the position of the socket 23 on the positioning block 2, which improves the installation accuracy and convenience.

[0030] Reference Figure 4A first slide groove 16 is provided at the top of the base 1, and an insert block 161 is slidably arranged in the first slide groove 16. A plug-in groove 141 for inserting the insert block 161 is provided on the driving ring 14. A first elastic member 162 is provided in the first slide groove 16 for driving the insert block 161 to slide toward the driving ring 14.

A connecting groove 17 is provided at the top of the base 1 along the sliding direction of the insert block 161, and a pressing block 171 is slidably arranged in the connecting groove 17. A connecting port 172 communicating with the first slide groove 16 is provided on the side wall of the connecting groove 17. A connecting block 173 is slidably arranged in the connecting port 172, and the connecting block 173 is respectively fixedly connected to the pressing block 171 and the insert block 161. After the drive ring 14 rotates and locks the positioning block 2, the first elastic member 162 acts to automatically insert the plug block 161 into the plug slot 141, thereby fixing the drive ring 14. This effectively prevents the drive ring 14 from accidentally loosening during operation, ensures the stability of the positioning block 2, and further improves the quality and consistency of the mirror processing of the split copper mirror of the optical gate. When the positioning block 2 needs to be replaced, the pressing block 171 can be pressed to allow the connecting block 173 to drive the plug block 161 out of the plug slot 141, thereby unlocking the drive ring 14.

[0031] Reference Figure 1 , 4 The limiting mechanism includes a limiting cover 25 and a limiting assembly. The limiting cover 25 is made of wear-resistant plastic, and its inner diameter is slightly larger than the diameter of the positioning block 2, and is rotatably sleeved on the positioning block 2. A guide block 251 is fixedly provided on the inner side wall of the limiting cover 25. An arc groove 26 is opened on the side wall of the positioning block 2 along the circumference of the positioning block 2, and the guide block 251 is slidably set in the arc groove 26, so that the limiting cover 25 can rotate freely on the positioning block 2.

[0032] Reference Figure 5 The limiting cover 25 is provided with two notches 252, and the edges on both sides of the notches 252 are inclined and gradually narrow in the direction close to the positioning block 2. Through the setting of the notches 252, the pressure strip 3 can smoothly enter the receiving groove 22. When the pressure strip 3 enters the receiving groove 22, the limiting cover 25 is rotated and the pressure strip 3 is pressed tightly in the receiving groove 22, so that the pressure strip 3 can be prevented from escaping from the receiving groove 22.

[0033] Reference Figure 4The limiting assembly includes a limiting block 27 and a second elastic member 28. A second slide groove 29 is provided at the top of the positioning block 2.

A ball 271 is provided at the end of the limiting block 27 away from the positioning block 2. A slot 253 adapted to the ball 271 is provided on the inner wall of the limiting cover 25. The limiting block 27 can slide freely in the second slide groove 29 and automatically move in a direction away from the positioning block 2 under the action of the second elastic member 28. When the limit cover 25 rotates to a specific position, the ball 271 can be accurately inserted into the slot 253 on the limit cover 25, exerting a certain resistance on the limit cover 25, and preventing the limit cover 25 from further rotating to a certain extent, thereby ensuring that the pressure strip 3 will not slide out of the receiving groove 22, and achieving a stable fixation of the special-shaped connection part of the optical shutter split copper mirror. In addition, the design of the ball 271 at the end of the limit block 27 reduces friction, making the rotation of the limit cover 25 smoother, and improving the overall reliability and service life of the tooling.

The design of the pressure strip 3 enables the special-shaped connection part of the split copper mirror of the light gate to be firmly pressed and fixed on the positioning block 2, ensuring the stability during the processing process. The high-efficiency and high-precision installation and positioning of the split copper mirror of the gate is achieved, thereby ensuring the processing quality of the mirror surface of the split copper mirror of the light gate.

[0036] Furthermore, the positioning block 2 is fixed to the base 1 by a fixing mechanism, so that the positioning block 2 and the base 1 can be detachably matched, which is convenient for maintenance or replacement of the positioning block 2. In addition, when in use, the corresponding positioning block 2 can be customized according to the shape of the special-shaped connection part of the optical shutter split copper mirror to be processed, and installed on the base 1, thereby improving practicality.
