Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, and in particular to an optical lens clamp. Background Technology

[0002] Optical lenses are commonly used testing tools in optical experiments. To ensure the accuracy of the experiment, the processing precision requirements of optical lenses are generally high. After the rough machining of the lens blank, the rough-machined optical lens needs to be ground. During the grinding process, the optical lens needs to be clamped to cooperate with the grinding head for grinding.

[0003] In the prior art, when fixing optical lenses that need to be ground, three sets of clamps are often used to limit the lens at three points. However, this method has few clamping points and insufficient stability, which makes the lens prone to displacement during grinding and affects the grinding accuracy. In order to solve the above problems, an optical lens grinding fixture is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an optical lens clamp to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An optical lens fixture includes a processing table, a lens body, and a clamping cylinder. Three sets of guide grooves are evenly spaced on the top side of the processing table. An inner slide seat is slidably disposed inside each guide groove. A mounting base is connected to the front end of the inner slide seat via a push rod. A main clamping block is located at the front end of the mounting base and presses against the edge of the lens body positioned at the center of the processing table. Connecting rods are movably connected to both sides of the mounting base via pins. A clamping arm is connected to one end of each connecting rod. An auxiliary clamping block is located on the inner side of the clamping arm and presses against the outer wall surface of the lens body.

[0007] Preferably, a guide seat is provided at the top position of the inner slide, and an outer slide is slidably provided outside the guide seat.

[0008] Preferably, both sides of the outer slide are connected to side supports, one end of the side support is movably connected to a connecting rod via a pin, and one end of the connecting rod is movably connected to one side of the middle of the clamping arm.

[0009] Preferably, the guide seat has a traction groove inside, a traction slider is slidably disposed inside the traction groove, and the top end of the traction slider is connected to the bottom of the outer slide seat. The traction groove has a traction screw inside, and one end of the traction screw is threadedly connected to the traction slider.

[0010] Preferably, the outer wall of the guide seat is provided with a plurality of positioning holes, and a positioning rod is threadedly connected to the outer side of the outer slide, with one end of the positioning rod passing through the outer slide and threadedly connected to the inside of the positioning hole.

[0011] Preferably, three sets of clamping cylinders are installed at the edge of the processing table, and the output end of the clamping cylinder is connected to one end of the inner slide through the clamping rod. The clamping cylinder is a commercially available device known to those skilled in the art. Here we are only using it without making any structural or functional improvements, and we will not go into details here.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This application provides three sets of inner slides on the side of the processing table, which are driven by clamping cylinders. The clamping cylinders drive the inner slides, which in turn drive the main clamping block to press against the edge of the lens for clamping and limiting. At the same time, clamping arms and auxiliary clamping blocks are connected to both sides of the mounting base. The auxiliary clamping blocks also press against the outer wall surface of the lens, working together with the main clamping block to clamp the lens. In this way, there are multiple clamping points on the outer side of the lens, which improves the stability of the lens during fixation and makes it less likely to slip. Furthermore, guide seats are provided on the outside of the inner slides to guide and support the outer slides. The side supports on both sides of the outer slides push the clamping arms for clamping via connecting rods, thereby allowing adjustment of the clamping degree of the clamping arms.

[0020] This utility model provides, for example Figure 1-4 An optical lens fixture is shown, including a processing table 1, a lens body 2, and a clamping cylinder 4. Three sets of guide grooves 3 are provided on the top side of the processing table 1, and the three sets of guide grooves 3 are evenly spaced. An inner slide seat 8 is slidably arranged inside the guide groove 3. The front end of the inner slide seat 8 is connected to a mounting seat 16 via a push rod. A main clamping block 17 is provided at the front end of the mounting seat 16, and the main clamping block 17 is pressed against the edge of the lens body 2 located at the center of the processing table 1. The two sides of the mounting seat 16 are movably connected to connecting rods 7 via pins. One end of the connecting rod 7 is connected to a clamping arm 5. An auxiliary clamping block 6 is provided on the inner side of the clamping arm 5, and the auxiliary clamping block 6 is pressed against the outer wall surface of the lens body 2.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an optical lens clamp. Specifically, a guide seat 10 is provided at the top of the inner slide seat 8, and an outer slide seat 11 is slidably provided outside the guide seat 10. The outer slide seat 11 can slide outside the guide seat 10.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an optical lens clamp. Specifically, both sides of the outer slide 11 are connected to side supports 9. One end of the side support 9 is movably connected to a connecting rod 7 via a pin, and one end of the connecting rod 7 is movably connected to one side of the middle part of the clamping arm 5.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model discloses an optical lens clamp. Specifically, the guide seat 10 has a traction groove inside, and a traction slider 13 is slidably arranged inside the traction groove. The top end of the traction slider 13 is connected to the bottom of the outer slide seat 11. A traction screw 15 is arranged inside the traction groove, and one end of the traction screw 15 is threadedly connected to the traction slider 13. In this application, the traction screw 15 drives the traction slider 13 to slide. The traction screw 15 is a commercially available device known to those skilled in the art. Here, we are only using it without making any structural or functional improvements, and we will not go into detail here.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an optical lens clamp. Specifically, the outer wall of the guide seat 10 is provided with multiple positioning holes 12. The outer side of the outer slide 11 is threadedly connected to a positioning rod 14. One end of the positioning rod 14 passes through the outer slide 11 and is threadedly connected to the inside of the positioning hole 12. After the position of the outer slide 11 is adjusted, the positioning rod 14 can be rotated to limit the position of the outer slide 11 and prevent the outer slide 11 from slipping.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an optical lens fixture.

The clamping cylinder 4 is a well-known device that can be directly purchased from the market and is known to those skilled in the art. Here we are just using it without making any structural or functional improvements, and we will not go into details here.

[0026] The working principle of this utility model is as follows: When using the fixture of this application, the lens is placed at the top center of the processing table 1, and then the three sets of clamping cylinders 4 are activated. The clamping cylinders 4 push the inner slide seat 8 inside the guide slide groove 3 to slide. When the inner slide seat 8 slides, it drives the mounting seat 16 and the main clamping block 17 to move toward the lens on the processing table 1. Thus, the main clamping block 17 is pressed against the outside of the lens to clamp and limit the lens. At the same time, the auxiliary clamping block 6 at one end of the clamping arm 5 is also pressed against the outside of the lens, and together with the main clamping block 17, the lens is fixed and clamped. In this way, with multiple fixation points, the stability of the lens is higher when clamped. The limiting tightness of the auxiliary clamping block 6 can also be adjusted. The traction screw 15 can be rotated, and the outer slide seat 11 is driven to slide through the traction screw 15, so that the outer slide seat 11 drives the side support 9 and the connecting rod 7 to move toward the front end. Then, the connecting rod 7 pushes the clamping arm 5, so that the clamping arm 5 is further clamped and limited.
