Description

Technical Field

[0001] The utility model relates to the technical field of adjustable fine grinding and polishing devices, in particular to an adjustable fine grinding and polishing device for a plano-convex lens. Background Art

[0002] The processing process of plano-convex lens is: blanking, rough grinding, fine grinding, polishing and edge grinding. Blanking and rough grinding are necessary steps for plano-convex lens. Fine grinding and polishing are to process the working surface of plano-convex lens, and edge grinding is to correct the center error of plano-convex lens. Before the edge grinding step, the edge thickness of plano-convex lens must be controlled within a certain range, so that the plano-convex lens can be processed into a qualified lens. If the edge thickness difference of plano-convex lens exceeds the allowable range, the plano-convex lens cannot be processed into a qualified product.

[0003] The existing adjustable fine grinding and polishing device of the plano-convex lens generally uses a clamping block to laterally squeeze the side of the plano-convex lens so that the plano-convex lens is stably fixed on the fine grinding and polishing aid to facilitate the completion of subsequent polishing steps. However, the grinding work of the plano-convex lens is not just a lateral force. When the side of the plano-convex lens is fine-polished, the plano-convex lens will be subjected to a longitudinal fine grinding and polishing force, causing the position of the plano-convex lens to move up and down, thereby affecting the fine grinding and polishing effect. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides an adjustable fine grinding and polishing device for a plano-convex lens, which solves the problem that the grinding work of the plano-convex lens is not only a lateral force. When the side of the plano-convex lens is finely ground and polished, the plano-convex lens will be subjected to a longitudinal fine grinding and polishing force, causing the position of the plano-convex lens to move up and down, thereby affecting the fine grinding and polishing effect.

DETAILED DESCRIPTION

[0025] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example 1

[0027] See also Figure 1-Figure 4 The adjustable fine grinding and polishing device for the plano-convex lens of this embodiment includes a base 1, a transverse clamping structure 2 and a longitudinal clamping structure 3. The transverse clamping structure 2 is fixedly installed on the top of the base 1; and two longitudinal clamping structures 3 are arranged on the transverse clamping structure 2.

[0028] The transverse clamping structure 2 includes a shell 21, a limiting rod 22, a threaded rod 23, a handwheel 24, two clamping blocks 25 and a fine grinding and polishing aid 26; the shell 21 is fixedly installed on the top of the base 1; a slide groove 211 is provided in the shell 21; a limiting rod 22 is fixedly installed in the slide groove 211; a threaded rod 23 is rotatably installed in the slide groove 211, and the threads at both ends of the threaded rod 23 are in opposite directions; one end of the threaded rod 23 passes through the shell 21 and is fixedly installed with a handwheel 24; two clamping blocks 25 are screwed on the threaded rod 23, and the clamping blocks 25 slide on the limiting rod 22; a fine grinding and polishing aid 26 is fixedly installed on the shell 21.

[0029] The longitudinal section of the limiting rod 22 is circular, so that the clamping block 25 can play a limiting role when it moves under the action of the threaded rod 23.

[0030] The surface of the hand wheel 24 is bonded with anti-skid rubber to improve the grip feel and anti-skid property of the hand wheel 24 .

[0031] A buffer pad 251 is fixedly installed on one side of the clamping block 25 close to the fine grinding and polishing aid 26, which can reduce the rigid clamping of the clamping block 25 on the plano-convex lens and avoid damage caused by excessive clamping force.

[0032] The main body material of the buffer pad 251 is rubber, which has good elasticity and wear resistance, thereby improving the service life of the buffer pad 251.

[0033] The cross section of the fine grinding and polishing aid 26 is square, so that the contact area of ​​the bottom of the plano-convex lens is uniform when it is placed.

[0034] The two longitudinal clamping structures 3 include a shell 2 31, a threaded rod 2 32, a hand wheel 2 33 and a clamping block 2 34; the shell 2 31 is fixedly installed to the top of the clamping block 1 25; a slide groove 2 311 is provided in the shell 2 31; a slide groove 312 is provided on the adjacent side of the slide groove 2 311; a threaded rod 2 32 is rotatably installed in the slide groove 2 311; the top of the threaded rod 2 32 passes through the shell 2 31 and is fixedly installed with a hand wheel 2 33; a clamping block 2 34 is screwed on the threaded rod 2 32, and the clamping block 2 34 slides on the slide groove 312.

[0035] A buffer pad 341 is fixedly installed at the bottom of the clamping block 34 to reduce the rigid clamping of the plano-convex lens by the clamping block 34 and avoid damage caused by excessive clamping force.

[0036] The main body material of the buffer pad 2 341 is rubber, which has good elasticity and wear resistance, thereby improving the service life of the buffer pad 2 341 .

[0037] Working principle: First, the staff places the plano-convex lens on the fine grinding and polishing aid 26, and then the staff holds the hand wheel 24 and rotates it clockwise, and the hand wheel 24 simultaneously drives the threaded rod 23 to rotate clockwise, and the threaded rod 23 applies a clockwise rotation force to the clamping block 25, and the clamping block 25 is restricted by the limit rod 22, so that the clamping block 25 can only move laterally along the limit rod 22. Because the threads at both ends of the threaded rod 23 have opposite screw directions, when the threaded rod 23 applies a clockwise rotation force to the two clamping blocks 25, the clamping block 25 moves toward the fine grinding and polishing aid 26 under the restriction of the limit rod 22. As the clamping block 25 continues to move laterally, the buffer pads 251 on the clamping blocks 25 on both sides clamp the side of the plano-convex lens to complete the lateral limitation of the plano-convex lens.

[0038] After the plano-convex lens is laterally limited, the staff can rotate handwheel 2 33 clockwise and make it rotate clockwise. Handwheel 2 33 synchronously drives threaded rod 2 32 to rotate clockwise. Threaded rod 2 32 applies a clockwise rotation force to clamping block 2 34. Clamping block 2 34 is restricted by slide grooves 312 on both sides, so that clamping block 2 34 can only move longitudinally along slide grooves 312. Threaded rod 2 32 applies a clockwise rotation force to clamping block 2 34. Clamping block 2 34 moves downward under the restriction of slide grooves 312. As clamping block 2 34 continues to move longitudinally, buffer pad 2 341 on clamping block 2 34 squeezes the top of the plano-convex lens to complete the longitudinal limitation of the plano-convex lens.

[0039] To sum up, the adjustable fine grinding and polishing device for the plano-convex lens is used in conjunction with the base 1, the transverse clamping structure 2 and the longitudinal clamping structure 3. When the plano-convex lens is placed on the fine grinding and polishing aid 26, the staff holds the hand wheel 24 and rotates it clockwise, and the two clamping blocks 25 move toward the middle under the action of the threaded rod 23 to complete the lateral limitation of the plano-convex lens. Then the staff holds the hand wheel 2 33 and rotates it clockwise, and the clamping block 2 34 moves downward under the action of the threaded rod 2 32 to complete the longitudinal limitation of the plano-convex lens, thereby achieving the longitudinal and lateral dual limitation of the plano-convex lens, ensuring the stability of the plano-convex lens during fine grinding and polishing.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
