Description

Technical Field

[0001] The utility model relates to the field of clamping devices, and particularly relates to a clamping device for assembling a lens lens mount. Background Art

[0002] The lens is the most important component in a camera because its quality directly affects the quality of the captured image. The assembly of the lens and the lens mount is a process involving precise operations and professional techniques, and is usually used in the lens systems of cameras, video cameras, mobile phones and other devices. Currently, a robotic arm is usually used to grab and clamp the lens and screw it into the lens mount for assembly. However, only relying on the jaws on the robotic arm to hold the lens, the clamping effect is relatively average, and the lens may rotate relative to the jaws during assembly, affecting the assembly quality. In the existing patent application with the application number CN202122321731.4, a clamping device for assembling a lens lens mount is proposed. Although it improves the clamping effect on the lens to a certain extent and ensures the assembly quality to a certain extent by adding a clamping plate, a housing and a suction cup, starting the hydraulic rod to drive the connecting plate to move upward, and the two clamping plates move inward simultaneously to clamp the outer end of the lens. At the same time, driving the connecting column and the piston plate to move upward, the suction cup adsorbs on the lens, and through the combined action of the suction cup and the clamping plate, and by adding an adjustment component, the distance between the two clamping plates can be adjusted to clamp lenses of various sizes. However, since the radian of the arc-shaped groove opened at the inner end of the clamping plate is fixed, and the radians of lenses of different sizes are different, when the radian of the lens to be clamped is different from the radian of the arc-shaped groove opened on the clamping plate, it is difficult for the clamping plate to closely adhere to the lens, resulting in a small contact area between the clamping plate and the lens, and ultimately the lens cannot be effectively clamped. Therefore, when the lens is screwed into the lens mount, the lens is likely to slide relative to the clamping plate, and the lens is likely to be unable to be installed in place, resulting in poor assembly quality of the lens and the lens mount. Therefore, it needs to be improved. Summary of the Invention

The rubber anti-slip pad is fixedly installed on the inner wall of the elastic arc plate, and the mounting frame is fixedly installed on the outer wall of the elastic arc plate. Four connecting frames are symmetrically and fixedly installed on the outer wall of the elastic arc plate. The connecting frame is composed of a fixed frame and a fixed shaft.

Detailed Description of the Preferred Embodiments

[0018] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in the figure, a clamping device for assembling a lens lens mount includes a clamping cylinder 1. Two clamping jaws 2 are installed on the clamping cylinder 1. A substrate 3 is fixedly installed on each of the two clamping jaws 2. Four adjusting components 4 are symmetrically arranged on the substrate 3. A connecting block 5 is installed at the inner end of the adjusting component 4. A radian-adjustable clamping member 6 is fixedly installed at the inner end of each of the two substrates 3. The radian-adjustable clamping member 6 is composed of an elastic arc plate 12, a rubber anti-slip pad 13, and a mounting bracket 14. The rubber anti-slip pad 13 is fixedly installed on the inner wall of the elastic arc plate 12. The mounting bracket 14 is fixedly installed on the outer wall of the elastic arc plate 12. Four connecting brackets 7 are symmetrically and fixedly installed on the outer wall of the elastic arc plate 12. The connecting bracket 7 is composed of a fixed bracket 15 and a fixed shaft 16. The fixed shaft 16 is fixedly installed in the fixed bracket 15, and the connecting block 5 is rotatably installed on the fixed shaft 16 at the same time. When in use, when the clamping cylinder 1 drives its telescopic rod to contract inward, the two clamping jaws 2 will approach each other. At this time, the clamping jaws 2 drive the radian-adjustable clamping member 6 to move inward through the substrate 3. Finally, the two radian-adjustable clamping members 6 will clamp the lens. Then, the clamped lens can be screwed into the lens mount. At this time, the assembly of the lens and the lens mount is completed. When it is necessary to change the radian of the radian-adjustable clamping member 6 according to the radian of the lens to be clamped, the radian of the radian-adjustable clamping member 6 can be changed by rotating the adjusting component 4. When the adjusting component 4 moves inward on the substrate 3, the radian of the radian-adjustable clamping member 6 will become smaller. At this time, the radian-adjustable clamping member 6 can closely adhere to a lens with a smaller diameter. When the adjusting component 4 moves outward on the substrate 3, the radian of the radian-adjustable clamping member 6 will become larger. At this time, the radian-adjustable clamping member 6 can closely adhere to a lens with a larger diameter. When rotating the adjusting component 4, the adjusting component 4 will rotate relative to the connecting block 5. At the same time, as the adjusting component 4 moves inward or outward, it will drive the connecting block 5 to move. At this time, the moving connecting block 5 will rotate relative to the connecting bracket 7. By setting the substrate 3, the adjusting component 4, the connecting block 5, the radian-adjustable clamping member 6, and the connecting bracket 7, the radian of the elastic arc plate 12 and the rubber anti-slip pad 13 on the radian-adjustable clamping member 6 can be changed by rotating the adjusting component 4, so that the radian of the radian-adjustable clamping member 6 can be adjusted according to the radian of the lens to be clamped, and further the radian-adjustable clamping member 6 can closely adhere to lenses of different sizes, so that the radian-adjustable clamping member 6 has a large contact area with lenses of different sizes. Finally, lenses of different sizes can be effectively clamped, so that when the lens is screwed into the lens mount, the lens is not easy to slide relative to the radian-adjustable clamping member 6, and further the lens can be effectively installed in place, and the assembly quality of the lens and the lens mount is good.

[0020] Further, the substrate 3 is fixedly connected to the jaw 2 by bolts. Four threaded holes 8 are symmetrically formed in the substrate 3, and the threaded holes 8 penetrate through the substrate 3 inside and outside. The adjusting assembly 4 is composed of a threaded rod 9 and a rotating block 10. The rotating block 10 is fixedly installed at the outer end of the threaded rod 9. The threaded rod 9 on the adjusting assembly 4 is installed in the threaded hole 8 formed in the substrate 3. The rotating block 10 is located outside the substrate 3. A connecting groove is formed at the inner end of the threaded rod 9. The threaded rod 9 can be rotated by rotating the rotating block 10. When the threaded rod 9 rotates in the threaded hole 8 of the substrate 3, the threaded rod 9 will move inward or outward.

[0021] Further, one end of the connecting block 5 is fixedly installed with a mounting block, and the mounting block is simultaneously rotatably installed in the connecting groove formed at the inner end of the threaded rod 9. The connecting block 5 is located inside the fixing frame 15. A shaft hole 11 is formed in the connecting block 5, and the connecting block 5 is simultaneously rotatably installed on the fixed shaft 16 through the shaft hole 11. Since the connecting block 5 is rotatably connected to the threaded rod 9, when the threaded rod 9 rotates, the connecting block 5 will not rotate with it. When the threaded rod 9 moves inward or outward, the connecting block 5 will move with it.

[0022] Further, the mounting frame 14 on the arc-adjustable clamping member 6 is fixedly installed at the inner end of the substrate 3, and the fixing frame 15 on the connecting frame 7 is fixedly installed on the outer wall of the elastic arc-shaped plate 12. When the connecting block 5 moves, it will rotate relative to the fixed shaft 16 on the connecting frame 7, and the connecting frame 7 will move with the connecting block 5. At the same time, the moving connecting frame 7 will drive the elastic arc-shaped plate 12 and the rubber anti-slip pad 13 on the arc-adjustable clamping member 6 to deform. When the connecting frame 7 is pushed inward, the elastic arc-shaped plate 12 and the rubber anti-slip pad 13 will bend inward. When the connecting frame 7 is driven outward, the degree of inward bending of the elastic arc-shaped plate 12 and the rubber anti-slip pad 13 will become smaller.
