Description

Technical Field

[0001] The utility model relates to the field of linear optical axes, and particularly to a linear optical axis with an anti-collision function. Background Technique

[0002] The linear optical axis has the guiding function of a sliding bearing and can be a shaft part that performs linear motion. It is widely used in many linear motion systems such as cylinder rods, automatic precision printers, automatic cutting machines, and industrial robots. In the actual use process of the existing linear optical axis, it is in a directly exposed state, and the surface is easily collided, resulting in the influence of the surface smoothness. Therefore, the Chinese authorized utility model patent (publication number: CN216975471U) discloses a highly stable anti-collision linear optical axis. By setting the stainless steel sleeve and the filling rod, during the actual use of the linear optical axis, the wrapping effect of the stainless steel sleeve can be utilized to prevent the linear optical axis body from being directly exposed, thereby playing a protective role for the linear optical axis and preventing the situation that the entire linear optical axis is scrapped due to collision. At the same time, the stainless steel sleeve itself has high strength and will not affect the normal use of the linear optical axis. At the same time, it is convenient to replace, which can fully ensure the use of the linear optical axis.

[0003] However, there are still some deficiencies in the above device during use: specifically, when the stainless steel sleeve is damaged due to long-term use or accidental collision, it needs to be replaced. However, the existing replacement method is relatively cumbersome. It is necessary to disassemble the linear optical axis from the optical axis support, and then the stainless steel sleeve can be disassembled and replaced, which increases the operation steps and difficulty, and is time-consuming and laborious. Therefore, in view of the above situation, a linear optical axis with an anti-collision function is proposed. Content of the Utility Model

[0004] In order to make up for the problem that the existing replacement method is relatively cumbersome, it is necessary to disassemble the linear optical axis from the optical axis support, and then the stainless steel sleeve can be disassembled and replaced. The utility model proposes a linear optical axis with an anti-collision function.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a linear optical axis with an anti-collision function, including a main shaft, a first steel sleeve, a second steel sleeve, and a limiting block. End rods are arranged at both ends of the main shaft, and external threads are provided on the outer walls of the end rods.

[0006] A circular groove is provided on the limiting block, a threaded hole is provided on the circular groove, the threaded hole is in threaded cooperation with the external thread, and an annular groove is also provided on the circular groove.

[0007] Protrusions are provided on the first steel sleeve, and there are two protrusions.

[0008] The second steel sleeve is provided with grooves. There are two grooves. When the second steel sleeve and the first steel sleeve are sleeved on the outer wall of the main shaft, the first steel sleeve and the second steel sleeve are combined into an annular steel sleeve. The convex block is in clamping fit with the groove, and the annular steel sleeve is in fit with the annular groove.

[0009] Preferably, screws are provided at the ends of both end rods, and the diameter of the screw is smaller than that of the end rod.

[0010] Preferably, both the first steel sleeve and the second steel sleeve are semi-circular rings.

[0011] Preferably, the minimum distance between the end of the annular steel sleeve and the end of the end rod is smaller than the minimum distance between the main shaft and the end of the end rod.

[0012] Preferably, the limiting block is circular in shape, and the outer wall of the limiting block has anti-slip lines.

[0013] Preferably, the outer surfaces of the first steel sleeve and the second steel sleeve are evenly coated with an anti-corrosion coating.

[0014] Preferably, both the first steel sleeve and the second steel sleeve are made of stainless steel.

[0015] Preferably, the outer surfaces of the main shaft, the end rod and the screw are all coated with an anti-corrosion coating.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. Through the structural design of the first steel sleeve, the convex block, the second steel sleeve, the groove and the limiting block, the present utility model realizes the protection of the main shaft during use. At the same time, when the first steel sleeve and the second steel sleeve are damaged, it is not necessary to disassemble the main shaft from the optical axis support, and they can be directly replaced, which simplifies the replacement process, reduces the operation steps, and improves the work efficiency.

[0018] 2. In the present utility model, the lengths of the first steel sleeve and the second steel sleeve are designed to be greater than the length of the main shaft. Furthermore, after the limiting block completes the secondary positioning of the first steel sleeve and the second steel sleeve, it can ensure that the linear bearing is not affected by the maximum moving stroke of the main shaft, thereby improving the performance of the device.

[0031] The second steel sleeve 5 is provided with grooves 501. There are two grooves 501. When the second steel sleeve 5 and the first steel sleeve 4 are sleeved on the outer wall of the main shaft 1, the first steel sleeve 4 and the second steel sleeve 5 are combined into an annular steel sleeve. The convex block 401 is in snap-fit with the groove 501, and the annular steel sleeve is in fit with the annular groove 603.

[0032] Among them, the split-designed annular steel sleeve is convenient for replacement when a part of the annular steel sleeve is damaged, which has the advantages of saving materials and reducing replacement costs.

[0033] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , screw rods 3 are arranged at the ends of both end rods 2, and the diameter of the screw rod 3 is smaller than that of the end rod 2.

[0034] In this embodiment, the screw rod 3 is used to connect with the optical axis support, and the diameter of the screw rod 3 is smaller than that of the end rod 2, which is convenient for the limit block 6 to be inserted from the end of the screw rod 3 and thread-connected with the end rod 2 at the initial stage of assembly.

[0035] Refer to Figure 1 、 Figure 2 and Figure 3 , both the first steel sleeve 4 and the second steel sleeve 5 are semi-circular rings, and both the first steel sleeve 4 and the second steel sleeve 5 are made of stainless steel.

[0036] In this embodiment, the stainless steel can specifically adopt SUS301 stainless steel. Compared with ordinary steel types, it has excellent high-temperature strength, fatigue resistance and corrosion resistance, and at the same time has a light weight and higher cost performance.

[0037] Refer to Figure 1 、 Figure 2 and Figure 3 , the minimum distance between the end of the annular steel sleeve and the end of the end rod 2 is less than the minimum distance between the main shaft 1 and the end of the end rod 2.

[0038] In this embodiment, with the above design, after the limit block 6 completes the positioning of the annular steel sleeve, it can ensure that the maximum moving stroke of the linear bearing on the main shaft 1 is not affected, thereby improving the service performance of the device.

At the same time, use another limiting block 6 to insert from the other end rod 2 to complete the threaded fit with the external thread 201, and at the same time complete the positioning of the annular steel sleeve.

[0044] When it is necessary to disassemble the annular steel sleeve for replacement, rotate the limiting block 6 counterclockwise to separate the annular steel sleeve from the annular groove 603, and then the clamped first steel sleeve 4 and the second steel sleeve 5 can be removed.
