Description

Technical Field

[0001] The utility model relates to a fixing device, in particular to a fixing device for processing lenses of optical instruments. Background Technique

[0002] A lens is made according to the law of refraction of light. During the processing steps such as grinding and polishing of the lens, it is first necessary to use a fixing device to fix the lens.

[0003] For example, a fixing device for processing lenses of optical instruments with a publication number of CN221677009U disclosed in a Chinese patent belongs to the technical field of lens processing, including an equipment box. A horizontal support plate is horizontally fixed in the inner cavity of the equipment box. Four groups of through grooves are oppositely arranged on the top of the horizontal support plate and the inner cavity of the equipment box. An activity tube is movably arranged in the inner cavity of the through groove. In the utility model, a driving component drives a turntable to rotate, so that the rotation rotates. By squeezing the activity tube through an arc-shaped guide groove, the activity tube moves inwards in the through groove, and then cooperates with a limit ring to clamp and fix the outer side of the lens. At the same time, the worm gear and the worm in the driving component have a self-locking function, which can suppress the shaking generated by the reverse rotation of the turntable and ensure the firmness of the clamping. Then, a connecting rod is movably arranged in the activity tube. The connecting rod moves downwards under the carrying of a lifting component to limit and clamp the top of the lens, ensuring that the lens placed on the top of the equipment box is stably clamped, facilitating the processing of the lens;

[0004] When using the above-mentioned existing fixing device for processing lenses of optical instruments, some problems are found. First, the device uses the guide groove on the turntable to synchronously adjust the limit ring. However, the lenses have different shapes according to their uses, and the common ones are circular, oval, etc. The synchronously moving limit ring can only clamp and fix circular lenses. Second, the clamping plate is located above the lens. When processing the surface of the lens, the clamping plate may interfere with the processing component. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fixing device for processing lenses of optical instruments to solve the existing problems mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A fixing device for processing lenses of optical instruments, including a base and a lens to be processed. A support cylinder is fixedly connected to the center of the upper surface of the base. A rubber sealing ring is fixedly connected to the upper edge of the support cylinder. An air pump is fixedly connected to the upper surface of the base. The output end of the air pump is communicated with the inside of the support cylinder through a pipeline. Four limit chutes are opened on the upper surface of the base. A limit component is slidably installed in the limit chute. The limit component includes a limit slider and a limit post. The limit slider is slidably matched with the limit chute. The limit post cooperates with the lens to be processed.

[0007] Preferably, a threaded adjusting rod is rotatably installed in the limiting sliding groove, and a knob is fixedly connected to one end of the threaded adjusting rod.

[0008] Preferably, a threaded through hole is formed in the limiting slider, and the threaded through hole is in threaded fit with the threaded adjusting rod.

[0009] Preferably, a scale is engraved on the upper surface of the base and on one side of the limiting sliding groove, and a pointer is fixedly connected to one side of the limiting slider, and the pointer cooperates with the scale.

[0010] Preferably, a threaded connecting rod is fixedly connected to the upper surface of the limiting slider, and a threaded connecting hole is formed in the lower surface of the limiting column, and the threaded connecting hole is in threaded fit with the threaded connecting rod.

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

[0012] 1. By using negative pressure to adsorb the lens to be processed on the support cylinder, the limiting component abuts against the periphery of the lens to be processed, restricting the lateral sliding of the lens to be processed, thereby effectively fixing the lens to be processed. At the same time, each limiting component can be adjusted independently, enabling the limiting component to adjust its position according to the shape of the lens to be processed, and then fixing lenses to be processed with different shapes.

[0013] 2. By the threaded fit between the threaded connecting rod and the threaded connecting hole, the threaded connecting hole is connected above the limiting slider, and rotating the limiting column can adjust its own height, avoiding the problem that the top of the limiting column is higher than the upper surface of the lens to be processed and interfering with the processing mechanism.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a fixing device for processing an optical instrument lens, including a base 1 and a lens 4 to be processed. A support cylinder 101 is fixedly connected to the center of the upper surface of the base 1, and a rubber sealing ring 102 is fixedly connected to the upper edge of the support cylinder 101. An air pump 103 is fixedly connected to the upper surface of the base 1, and the output end of the air pump 103 is communicated with the inside of the support cylinder 101 through a pipeline. Four limit sliding grooves 2 are opened on the upper surface of the base 1, and a limit assembly 3 is slidably installed in the limit sliding grooves 2. The limit assembly 3 includes a limit slider 301 and a limit post 302. The limit slider 301 is slidably matched with the limit sliding groove 2, and the limit post 302 cooperates with the lens 4 to be processed.

[0020] In this implementation scheme, by placing the lens 4 to be processed on the support cylinder 101, the rubber sealing ring 102 will replace the support cylinder 101 to contact the lens 4 to be processed. First, it avoids scratching the surface of the lens 4 to be processed. Second, the rubber sealing ring 102 has a certain deformation ability and can better fit the surface of the lens 4 to be processed. Starting the air pump 103 can extract the air inside the support cylinder 101, and then use negative pressure to adsorb the lens 4 to be processed on the support cylinder 101. The limit assembly 3 is slidably installed inside the limit sliding groove 2, and the position of the lens 4 to be processed is adjusted one by one, so that the limit assembly 3 abuts against the outer wall of the lens 4 to be processed, restricting the left and right sliding of the lens 4 to be processed. Because the force of the atmospheric pressure on the lens 4 to be processed is perpendicular to the plane, and the lens 4 to be processed is abutted by the limit assembly 3 around, the lens 4 to be processed is effectively fixed. The limit assembly 3 can be moved independently, so that each limit assembly 3 can be adjusted according to the shape of the lens 4 to be processed, enabling the device to fix lenses 4 to be processed with different shapes.

[0021] Among them, in order to achieve the purpose of adjusting the position of the limit assembly 3, the present device is realized by the following technical solution: a threaded adjustment rod 202 is rotatably installed in the limit sliding groove 2, a knob 203 is fixedly connected to one end of the threaded adjustment rod 202, and a threaded through hole 303 is opened in the limit slider 301. The threaded through hole 303 is in threaded cooperation with the threaded adjustment rod 202.

[0022] By turning the knob 203, the threaded adjustment rod 202 can be driven to rotate. The threaded adjustment rod 202 is in threaded cooperation with the threaded through hole 303. Furthermore, the rotation of the threaded adjustment rod 202 can drive the limit slider 301 to move, and the movement of the limit slider 301 can drive the limit assembly 3 to move, thereby adjusting the position of the limit assembly 3.

[0023] Among them, in order to achieve the purpose of adjusting the height of the limit post 302, the following technical solution is adopted in this device: There is a scale 201 engraved on the base 1 and on one side of the limit chute 2. A pointer 304 is fixedly connected to one side of the limit slider 301. The pointer 304 cooperates with the scale 201. A threaded connecting rod 305 is fixedly connected to the top of the limit slider 301. A threaded connection hole 306 is opened at the bottom of the limit post 302. The threaded connection hole 306 is in threaded cooperation with the threaded connecting rod 305.

[0024] Through the cooperation between the scale 201 and the pointer 304, it is convenient to accurately adjust the position of the limit assembly 3. The threaded connecting rod 305 is in threaded cooperation with the threaded connection hole 306, connecting the threaded connection hole 306 above the limit slider 301. Rotating the limit post 302 can adjust its own height, preventing the top of the limit post 302 from being higher than the upper surface of the lens 4 to be processed and interfering with the processing mechanism.

[0025] The working principle and usage process of the present utility model: When in use, the lens 4 to be processed needs to be placed on the rubber sealing ring 102. Rotate the limit post 302 to adjust its own height so that the top of the limit post 302 is not higher than the upper surface of the lens 4 to be processed. Subsequently, rotate the threaded adjustment rod 202 according to the shape of the lens 4 to be processed to adjust the position of the limit assembly 3, so that the limit post 302 abuts against the outer wall of the lens 4 to be processed, limiting the lens 4 to be processed and preventing it from shaking horizontally randomly. Start to pump out the air inside the support cylinder 101, and then use negative pressure to adsorb the lens 4 to be processed on the support cylinder 101, and the lens 4 to be processed can be fixed.

[0026] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
