Description

Technical Field

[0001] This utility model belongs to the field of linear optical axis technology, and in particular relates to a collision-proof linear optical axis. Background Technology

[0002] Linear optical axes are products that perform linear motion by guiding with sliding bearings. The essential requirements for these linear motion systems are: simple design, best performance, low maintenance costs, use of strictly selected robust and durable materials, high-frequency heat treatment, accurate outer diameter dimensions, roundness, straightness, and surface treatment. Existing linear optical axes are prone to collisions between the externally mounted components and the equipment at both ends of the linear optical axis during linear motion, which can easily lead to damage to the externally mounted components and significantly reduce the service life of the equipment. The anti-collision effect at both ends of the linear optical axis needs to be improved. Therefore, an anti-collision linear optical axis is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a collision-resistant linear optical axis. By incorporating a collision-resistant component, specifically, when the retaining ring is impacted, a buffer pad first cushions the force, while the retaining ring slides within the buffer cavity and compresses the elastic support. The elastic support generates a rebound force, further cushioning the force on the retaining ring. As the retaining ring slides within the buffer cavity, it compresses several springs, which in turn generate a rebound force, causing the retaining ring to reset. Simultaneously, these springs also cushion the force on the retaining ring, further enhancing the cushioning effect. This solves the problem that existing linear optical axes, where components mounted on the outside are prone to colliding with equipment at both ends of the linear optical axis during linear motion, easily leading to damage to these components and significantly reducing the equipment's lifespan, and highlighting the need to improve the collision-resistant effect at both ends of the linear optical axis.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a collision-resistant linear optical axis, comprising a main frame mechanism. The main frame mechanism includes a shaft body, with collision-resistant components arranged on both the left and right sides of the shaft body. Replacement components are located on the sides of the two sets of collision-resistant components that are far apart from each other. The replacement component on the left side includes a fixed bracket, and the collision-resistant component on the left side includes a retaining ring. A buffer pad is fixedly connected to the right side of the retaining ring, and a support sleeve is arranged on the left side of the retaining ring. Two elastic supports are arranged between the retaining ring and the support sleeve. A buffer cavity is formed inside the support sleeve near the retaining ring, and several springs are arranged inside the buffer cavity. The side of the spring away from the retaining ring is fixedly connected to the inner wall of the buffer cavity, and the right side of several springs is fixedly connected to the left side of the retaining ring. When the retaining ring is impacted, the buffer pad first buffers the force, and at the same time, the retaining ring slides inside the buffer cavity and squeezes the elastic support. The elastic support generates a certain rebound force and buffers the force on the retaining ring. When the retaining ring slides inside the buffer cavity, it squeezes several springs, and the several springs generate a certain rebound force and drive the retaining ring to reset. At the same time, the several springs also buffer the force on the retaining ring.

[0006] Furthermore, the inner wall of the buffer cavity is slidably connected to the left side of the outer surface of the retaining ring. Two elastic supports are disposed on the inner and outer rings of the retaining ring. The right sides of the two elastic supports are fixedly connected to the left side of the retaining ring. The side of the two elastic supports away from the retaining ring is fixedly connected to the right side of the support sleeve. A limiting annular groove is formed on the left side of the outer surface of the support sleeve. The inner wall of the support sleeve is in contact with the outer surface of the shaft. The left side of the inner wall of the fixed support is fixedly connected to the outer surface of the shaft. The elastic supports will contract and store force under the limiting effect of the support sleeve. At the same time, the elastic supports will generate a certain rebound force. At this time, the elastic supports will buffer the force on the retaining ring.

[0007] Furthermore, a gap exists between the fixed bracket and the shaft, and the inside of this gap is inserted into the side of the support sleeve away from the retaining ring. A sliding bracket is slidably connected to the outer surface of the fixed bracket, and a cavity is provided between the sliding bracket and the fixed bracket. A second spring is provided inside the cavity. The left side of the second spring is fixedly connected to the right side of the fixed bracket, and the right side of the second spring is fixedly connected to the left side of the sliding bracket. When the anti-collision device needs to be replaced due to wear after a period of use, the sliding bracket is moved away from the support sleeve, allowing the support sleeve to be removed and the anti-collision device to be replaced.

[0008] Furthermore, the fixed bracket has several limiting grooves on the side near the supporting sleeve, and each limiting groove contains a limiting ball. The outer surface of each limiting ball contacts the inner wall of the limiting annular groove. The sliding bracket is fixedly connected to a limiting ring on the side near the fixed bracket, and the side of the limiting ring away from the sliding bracket contacts the outer surface of the limiting balls. When the sliding bracket is released, the second spring will generate a certain rebound force and drive the sliding bracket to reset. When the sliding bracket resets, it will drive the limiting ring to move together. After the limiting ring resets, it will squeeze the limiting balls. At this time, the limiting balls will be embedded in the limiting annular groove under the force. At this time, the limiting balls limit and fix the supporting sleeve through the limiting annular groove, thus completing the installation of the anti-collision device.

[0009] This utility model has the following beneficial effects:

[0010] 1. This utility model, through the setting of anti-collision components, specifically, when the retaining ring is impacted, firstly, the buffer pad will buffer the force to a certain extent. At the same time, the retaining ring will slide inside the buffer cavity and compress the elastic support. The elastic support will generate a certain rebound force and buffer the force on the retaining ring. When the retaining ring slides inside the buffer cavity, it will compress several springs. These springs will generate a certain rebound force and drive the retaining ring to reset. At the same time, these springs will also buffer the force on the retaining ring, further improving the buffering effect, playing a certain anti-collision role, reducing damage to the equipment during use, and significantly extending the service life of the equipment.

[0011] 2. This utility model, through the setting of a replacement component, specifically involves moving the sliding bracket away from the support sleeve. As the sliding bracket moves, it compresses the second spring. The second spring, limited by the inner wall of the fixed bracket, contracts and stores force. At this point, the support sleeve can be inserted into the gap between the fixed bracket and the shaft. Then, the sliding bracket is released, and the second spring generates a certain rebound force, causing the limiting ring to compress several limiting balls. These limiting balls, through the limiting annular groove, limit and fix the support sleeve, thus completing the installation of the anti-collision device. This simple and convenient installation method significantly improves installation efficiency and greatly reduces the workload of workers. Furthermore, the ease of replacement of the anti-collision device helps improve its anti-collision effect.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5As shown, this utility model is a collision-resistant linear optical axis, including a main frame mechanism 1. The main frame mechanism 1 includes a shaft body 111. Collision-resistant components 2 are provided on both the left and right sides of the shaft body 111. Replacement components 3 are provided on the sides of the two sets of collision-resistant components 2 that are far apart from each other. The replacement component 3 on the left side includes a fixed bracket 311. The collision-resistant component 2 on the left side includes a retaining ring 211. A buffer pad 217 is fixedly connected to the right side of the retaining ring 211. A support sleeve 212 is provided on the left side of the retaining ring 211. Two elastic brackets 215 are provided between the retaining ring 211 and the support sleeve 212. A buffer cavity 216 is opened inside the support sleeve 212 on the side near the retaining ring 211. A plurality of springs 214 are provided inside the buffer cavity 216. The side of the plurality of springs 214 away from the retaining ring 211 is fixedly connected to the inner wall of the buffer cavity 216. The right side of spring 214 is fixedly connected to the left side of retaining ring 211. When retaining ring 211 is impacted, firstly, buffer pad 217 will buffer the force. At the same time, retaining ring 211 will slide inside buffer cavity 216 and compress elastic bracket 215. Elastic bracket 215 will generate a certain rebound force and buffer the force on retaining ring 211. When retaining ring 211 slides inside buffer cavity 216, retaining ring 211 will compress several springs 214. Then, several springs 214 will generate a certain rebound force and drive retaining ring 211 to reset. At the same time, several springs 214 will also buffer the force on retaining ring 211, further improving the buffering effect, playing a certain anti-collision role, reducing damage to equipment during use, and greatly extending the service life of equipment.

[0023] The inner wall of the buffer cavity 216 is slidably connected to the left side of the outer surface of the retaining ring 211. Two elastic supports 215 are set on the inner and outer rings of the retaining ring 211, and the right side of the two elastic supports 215 is fixedly connected to the left side of the retaining ring 211.

[0024] The two elastic brackets 215 are fixedly connected to the right side of the support sleeve 212 on the side away from the retaining ring 211. A limiting annular groove 213 is opened on the left side of the outer surface of the support sleeve 212. The inner wall of the support sleeve 212 is in contact with the outer surface of the shaft 111. The left side of the inner wall of the fixed bracket 311 is fixedly connected to the outer surface of the shaft 111.

[0025] There is a gap between the fixed bracket 311 and the shaft 111. The inside of the gap is inserted into the side of the support sleeve 212 away from the retaining ring 211. A sliding bracket 312 is slidably connected to the outer surface of the fixed bracket 311. A cavity is provided between the sliding bracket 312 and the fixed bracket 311. A second spring 314 is provided inside the cavity. The left side of the second spring 314 is fixedly connected to the right side of the fixed bracket 311, and the right side of the second spring 314 is fixedly connected to the left side of the sliding bracket 312. When the sliding bracket 312 is moved away from the support sleeve 212, the sliding bracket 312 will compress the second spring 314. The second spring 314 is subjected to the pressure of the fixed bracket 311. The inner wall limiting action will contract and store force. At this time, the support sleeve 212 can be inserted into the gap between the fixed bracket 311 and the shaft 111. Then, the sliding bracket 312 is released. At this time, the spring 314 will generate a certain rebound force and drive the limiting ring 313 to squeeze several limiting balls 315. At this time, the several limiting balls 315 limit and fix the support sleeve 212 through the limiting annular groove 213. At this time, the installation of the anti-collision device is completed. The simple and convenient installation method greatly improves the installation efficiency and significantly reduces the workload of the workers. At the same time, the anti-collision device is easy to replace, which helps to improve the anti-collision effect of the equipment.

[0026] The fixed bracket 311 has several limiting grooves 316 on the side near the support sleeve 212. Each limiting groove 316 has a limiting ball 315 inside. The outer surface of the limiting ball 315 contacts the inner wall of the limiting annular groove 213. The sliding bracket 312 is fixedly connected to the limiting ring 313 on the side near the fixed bracket 311. The side of the limiting ring 313 away from the sliding bracket 312 contacts the outer surface of the limiting ball 315.

[0027] A specific application of this embodiment is as follows: In use, when the retaining ring 211 is impacted, the object first contacts the buffer pad 217, which buffers the force. Simultaneously, the retaining ring 211, under the influence of the force, moves towards the support sleeve 212 and slides within the buffer cavity 216. As the retaining ring 211 moves, it compresses the elastic support 215. The elastic support 215, limited by the support sleeve 212, contracts and stores force, generating a certain rebound force. At this time, the elastic support 215 buffers the force on the retaining ring 211, while the retaining ring 211 slides within the buffer cavity 216. 211 compresses several springs 214, causing them to contract and store force due to the limiting effect of the inner wall of the buffer cavity 216. Simultaneously, the springs 214 generate a certain rebound force, causing the retaining ring 211 to reset. The springs 214 also buffer the force on the retaining ring 211, further improving the buffering effect and providing a certain degree of anti-collision effect, reducing damage during use and significantly extending the equipment's service life. Furthermore, when the anti-collision device needs replacement due to wear after a period of use, the sliding bracket 312 is moved away from the support sleeve 212, allowing the support sleeve 212 to be removed. When replacing the anti-collision device, during installation, first move the sliding bracket 312 away from the support sleeve 212. As the sliding bracket 312 moves, it slides on the outer surface of the fixed bracket 311. Simultaneously, the sliding bracket 312 compresses the second spring 314. The second spring 314, limited by the inner wall of the fixed bracket 311, contracts and stores force. At this point, the support sleeve 212 can be inserted into the gap between the fixed bracket 311 and the shaft 111. When the support sleeve 212 is inserted, it compresses several limiting balls 315. Under the force, the limiting balls 315 move away from each other, and simultaneously, the limiting balls 315 can only enter the limiting groove 316. The sliding bracket 312 is then released, and the spring 314 will generate a certain rebound force, causing the sliding bracket 312 to reset. When the sliding bracket 312 resets, it will cause the limiting ring 313 to move together. After the limiting ring 313 resets, it will squeeze several limiting balls 315. At this time, the several limiting balls 315 will be embedded in the limiting annular groove 213 under the action of the force. At this time, the several limiting balls 315 limit and fix the support sleeve 212 through the action of the limiting annular groove 213. The installation of the anti-collision device is completed. The simple and convenient installation method greatly improves the installation efficiency and significantly reduces the workload of the staff. At the same time, the anti-collision device is easy to replace, which helps to improve the anti-collision effect of the device.
