[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 4 As shown, this utility model provides a tooling fixture for machining a main lens barrel, including an operating table 1. A clamping plate 7 is slidably connected to one side of the top of the operating table 1, and a clamping plate 8 is fixedly connected to the other side of the top of the operating table 1. A fixing plate 2 is fixedly connected to the top of the operating table 1. An adjusting screw 4 is threaded onto the inner surface of the fixing plate 2. One end of the adjusting screw 4 passes through the fixing plate 2 and is rotatably connected to the clamping plate 7. By setting the clamping plate 7 to be slidably connected to the operating table 1, and using the adjusting screw 4 threaded onto the fixing plate 2 to control the position of the clamping plate 7, flexible adjustment of main lens barrels of different sizes is achieved, which is convenient for clamping main lens barrels of different diameters and improves the versatility and applicability of the tooling fixture.

[0026] Specifically, two limiting rods 6 are slidably connected to the inner surface of the fixed plate 2. One end of each limiting rod 6 passes through the fixed plate 2 and is fixedly connected to the clamping plate 7. One end of each limiting rod 6 is fixedly connected to a limiting plate 5. A moving block 71 is fixedly connected to the bottom end of the clamping plate 7. Two long slots 711 are opened at the top of the operating table 1. Guide rails 712 are fixedly connected to the lower inner walls of the two long slots 711. The two moving blocks 71 are slidably connected to the two guide rails 712 respectively. The limiting rods 6 and guide rails 712 ensure that the clamping plate 7 moves stably along a straight line during the adjustment process, and prevent the clamping plate 7 from shifting or rotating during movement. This improves the accuracy and stability of the clamping operation and helps to ensure the processing accuracy of the main lens barrel.

[0027] like Figures 1 to 4 As shown, the end of the adjusting screw 4 away from the clamping plate 7 is fixedly connected to the adjusting handle 3, which allows the operator to manually operate the adjusting screw 4 without the need for additional tools. The operation is simple and quick, and the position of the clamping plate 7 can be adjusted quickly, which improves the convenience of use and the efficiency of operation of the tooling clamp.

[0028] Furthermore, the inner surfaces of clamping plate 7 and clamping plate 8 are provided with several receiving grooves 75, and the corresponding ends of clamping plate 7 and clamping plate 8 are provided with several rod grooves 77. The rod grooves 77 are connected to the receiving grooves 75 respectively. The inner surfaces of the rod grooves 77 are slidably connected with clamping rods 72. One end of the clamping rods 72 is fixedly connected with a slider 73. The outer surfaces of the sliders 73 are slidably connected to the inner surfaces of the receiving grooves 75 respectively. One end of the sliders 73 is provided with a return spring 74, which can make the tooling clamp the main lens barrel from multiple points, enhance the clamping firmness and uniformity, prevent the main lens barrel from rotating or shifting during processing, and improve the safety and reliability of processing.

[0029] like Figures 1 to 4 As shown, one end of the return spring 74 is fixedly connected to the slider 73, and the other end of the return spring 74 is fixedly connected to the inner wall of one side of the receiving groove 75. This not only prevents damage to the main lens barrel due to excessive clamping, but also allows it to automatically reset after the clamping rod 72 is released, ensuring the reusability and ease of operation of the tooling clamp.

[0030] It is worth noting that both the receiving groove 75 and the slider 73 have rectangular cross-sections, ensuring that the slider 73 can only slide in a straight line within the receiving groove 75, preventing the slider 73 from rotating, ensuring the stability of the movement direction of the clamping rod 72, and further improving the clamping stability and reliability of the tooling clamp.

[0031] like Figures 1 to 4As shown, one end of several clamping rods 72 is fixedly connected to a clamping block 76. The clamping block 76 is made of rubber and is hemispherical. The rubber material has good elasticity, which can further buffer the clamping force and prevent damage to the surface of the main lens barrel. The hemispherical shape can better fit the outer surface of the main lens barrel, improve the clamping effect, and protect the surface quality of the main lens barrel.

[0032] Working principle and process: During the tooling operation of the main lens barrel, the main lens barrel is placed between clamping plate 7 and clamping plate 8. By rotating the adjusting handle 3, the adjusting screw 4 is rotated, causing axial movement. This pushes clamping plate 7 along the guide rail 712. The guide rail 712 guides the movement of clamping plate 7 through the long groove 711. At the same time, the limiting rod 6 and the limiting plate 5 ensure the linear stability of clamping plate 7. Clamping plate 7 moves closer to clamping plate 8 and gradually clamps. As clamping plates 7 and 8 approach the main lens barrel, clamping rod 72 slides within rod groove 77, and slider 73 slides within receiving groove 75, compressing return spring 74. Clamping block 76 then adheres to the surface of the main lens barrel, utilizing the elasticity of rubber and the hemispherical shape to better clamp the main lens barrel. Multiple clamping rods 72 clamp the main lens barrel evenly from multiple positions. After processing is complete, rotating the adjusting handle 3 in the opposite direction releases clamping plate 7, and return spring 74 springs the clamping rod 72 back, facilitating the removal of the main lens barrel.
