Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a fixture for processing lens spacers. Background Technology

[0002] Lens spacers, as a crucial component of optical lenses, require high precision in their manufacturing, especially during the grinding of the inner and outer rings. Traditional lens spacer machining fixtures often employ a single clamping method, typically holding the lens spacer from the outside using a jig. However, this traditional method often suffers from unstable fixation and difficulty in guaranteeing machining accuracy. Particularly during the grinding of the inner and outer rings, the lens spacer is prone to displacement or deformation, affecting the final machining quality. Furthermore, the direct contact forces generated during clamping can damage the surface of the lens spacer, thereby affecting its optical performance.

[0003] To improve the machining accuracy and efficiency of lens spacers, some existing technologies employ a double-clamp structure for fixation. However, most designs fail to simultaneously address the grinding needs of both the inner and outer rings, and their control over clamping force is limited. Clamping methods lacking a buffer structure may result in excessive clamping force or uneven force distribution, thereby causing unnecessary damage to the lens spacer. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture for processing lens spacers, which has the advantages of precise clamping, simultaneous grinding of inner and outer rings, and force buffer protection. It solves the problems of unstable clamping methods, excessive or uneven clamping force leading to damage to lens spacers, and insufficient processing accuracy caused by traditional clamping methods.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixture for processing lens spacers, comprising a base plate, a bracket on the base plate, and a moving device fixedly mounted on the bracket. The moving device includes a housing, two fixed blocks, and a drive motor. The housing is a hollow cavity structure with openings at the upper and lower ends. Two moving blocks, a lead screw, and a sliding rod are provided in the cavity. The lead screw is inserted through the moving blocks. Sliding grooves are provided on both sides of the lead screw on the moving blocks. The sliding rod slides in the sliding grooves. The fixed blocks are fixed on the moving blocks. The output end of the drive motor is connected to the lead screw.

[0006] Preferably, a material box is provided on the base plate directly below the bracket.

[0007] Preferably, the solid block includes two notches, a clamping block, a spring piston, and a buffer pad. The notches are located on the top two sides of the clamping block, the spring piston is installed through the middle of the top of the clamping block, and the buffer pad is connected to the spring piston.

[0008] Preferably, the notches are all arc-shaped.

[0009] Preferably, the spring piston includes a compression spring, a sleeve, and an inner column. The compression spring is mounted on the sleeve, and one end of the compression spring is connected to a limit block. The inner column is connected to the limit block.

[0010] Preferably, the buffer pad includes a metal pad and a silicone pad, with the silicone pad fixed to the metal pad.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, through the cooperation of a lead screw and a moving block, enables two fixed blocks to move in opposite directions or in opposite directions, achieving the effect of adjusting the position of the two fixed blocks according to the size of the lens spacer. The installation of the drive motor allows the lead screw to rotate, providing power output. Through the cooperation of the sliding rod and the sliding groove, the lead screw stabilizes both sides of the two moving blocks when the two blocks are moved by the threaded engagement, achieving the effect of indirectly stabilizing the movement of the two fixed blocks. By setting a notch, the clamping block can be inserted into the inner ring of the lens spacer when it clamps the outer ring or is inserted into the inner ring of the lens spacer, achieving the effect of providing a locking limit position. By setting a buffer pad, the lens spacer can be cushioned when it contacts its surface, achieving the effect of buffering and preventing wear caused by direct contact. Attached Figure Description

[0024] Please see Figures 1 to 6This utility model provides an embodiment of a fixture for processing lens spacers, comprising a base plate 1, a support 2 on the base plate 1, and a moving device 3 fixedly mounted on the support 2. The moving device 3 includes a housing 31, two fixed blocks 32, and a drive motor 33. The housing 31 is a hollow cavity structure with openings at the upper and lower ends. Two moving blocks 34, a lead screw 35, and a sliding rod 36 are provided in the cavity. The lead screw 35 is inserted through the moving block 34. The moving block 34 has sliding grooves 37 on both sides of the lead screw 35. The sliding rod 36 slides in the sliding grooves 37. The fixed blocks 32 are fixed on the moving block 34. The output end of the drive motor 33 is connected to the lead screw 35.

[0025] Please see Figures 1 to 6 Through the cooperation of lead screw 35 and moving block 34, the two fixed blocks 32 can move in opposite directions or in opposite directions, achieving the effect of adjusting the position of the two fixed blocks 32 according to the size of the lens spacer. The installation of drive motor 33 enables lead screw 35 to rotate, achieving the effect of power output. Through the cooperation of slide rod 36 and slide groove 37, lead screw 35 stabilizes both sides of the two moving blocks 34 when the two moving blocks 34 are moved by thread engagement, achieving the effect of indirectly stabilizing the movement of the two fixed blocks 32.

[0026] Specifically, a material box 4 is located on the base plate 1 directly below the bracket 2. The material box 4 allows debris generated during the processing of the lens spacer to fall into it through the bracket 2, providing a collection point for convenient and unified processing later.

[0027] Specifically, the fixed block 32 includes two notches 321, a clamping block 322, a spring piston 323, and a buffer pad 324. The notches 321 are located on both sides of the top of the clamping block 322. The spring piston 323 is installed through the middle of the top of the clamping block 322, and the buffer pad 324 is connected to the spring piston 323. By providing the notches 321, the clamping block 322 can be locked into the inner ring of the lens spacer when clamping it or when inserted into the inner ring of the lens spacer, thus achieving the effect of providing a locking and limiting position.

[0028] Specifically, notches 321 are all arc-shaped. The arc-shaped structure design allows the lens spacer to fit in more easily.

[0029] Specifically, the spring piston 323 includes a compression spring 3231, a sleeve 3232, and an inner post 3233. The compression spring 3231 is mounted on the sleeve 3232, and one end of the compression spring 3231 is connected to a limit block 3234. The inner post 3233 is connected to the limit block 3234. By setting the spring piston 323, the two buffer pads 324 placed in the recess 321 can be elastic, achieving elastic buffering when the lens spacer is inserted, thus avoiding damage caused by direct fixation.

[0030] Specifically, the buffer pad 324 includes a metal pad 3241 and a silicone pad 3242, with the silicone pad 3242 fixed to the metal pad 3241. By setting the buffer pad 324, the lens spacer can buffer the lens when it comes into contact with its surface, achieving the effect of buffering and preventing wear caused by direct contact.

[0031] Working Principle: Before using this utility model, the operator needs to connect an external power supply and control the operation of the utility model through a control platform. The operator places the lens spacer to be processed onto the two fixed blocks 32. After placing it, the operator controls the drive motor 33 to rotate in the reverse direction, and the lead screw 35 connected to the output end rotates. The rotating lead screw 35 will engage with the moving block 34, and the two moving blocks 34 will move in opposite directions, taking the two fixed blocks 32 connected to the surface with them. In this way, the lens spacer placed on the two fixed blocks 32 will be supported and fixed from the inside. After the lens spacer is fixed, the operator can use grinding and other devices to process its outer ring. If it is necessary to process the inner ring of the lens spacer, the operator places the lens spacer between the two fixed blocks 32, and then controls the drive motor 33 to rotate in the forward direction, and the lead screw 35 connected to the output end rotates. In this way, the two fixed blocks 32 will move towards each other and shorten the distance between them, clamping and fixing the lens spacer placed between them. At this time, the operator can perform grinding and other processing on the inner ring of the lens spacer.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
