Description

Technical Field

[0001] The utility model relates to the technical field of guide rails, in particular to a guide rail for an industrial robot. Background Art

[0002] The longitudinal grooves or ridges on the surface of the guide rail are used to guide and fix machine parts, special equipment, instruments, etc. The guide rail is also called a slide rail, a linear guide rail, or a linear slide rail. It is used in linear reciprocating motion occasions and has a higher rated load than linear bearings. At the same time, it can bear a certain torque and can achieve high-precision linear motion under high load conditions.

[0003] An existing guide rail for an industrial robot can refer to the utility model patent with Chinese patent publication number CN217967095U, which discloses a guide rail for an industrial robot, belonging to the field of guide rails. A guide rail for an industrial robot includes a track guide body, and telescopic mechanisms are provided on both sides of the track guide body. The telescopic mechanism is rotatably connected to a top plate at one end away from the track guide body. The telescopic mechanism includes an outer shell, and a support rod is slidably connected to the inside of the outer shell. One end of the support rod extends to the outside of the outer shell away from one end of the track guide body, and the end of the support rod extending to the outside of the outer shell is rotatably connected to the top plate, and the end of the outer shell away from the track guide body is rotatably connected to two clamping plates.

[0004] However, during the actual use of the device, it was found that although the device can achieve relatively simple installation and disassembly of the track, and has high stability, a wide range of applications, a relatively simple structure, and a low cost, it is difficult to manually turn the threaded ring in a hole with a smaller diameter, which affects the normal use of the device and thus has certain limitations. Therefore, the present application provides a guide rail for an industrial robot to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a guide rail for an industrial robot to solve the problem that it is difficult to manually turn the thread ring of the existing device in a hole with a smaller diameter, thereby affecting the normal use of the device and thus having certain limitations.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A guide rail for an industrial robot comprises: a guide rail body, the outer wall of the guide rail body is provided with a through groove, the inner wall of the through groove is provided with a circular groove, a motor is fixedly mounted on the inner wall of the circular groove, a gear is fixedly mounted on the top end of the motor output shaft, a tooth plate is meshed on the outer wall of the gear, a limiting groove is provided on the outer wall of the guide rail body, and the tooth plate is slidably connected to the limiting groove, the inner wall of the guide rail body is slidably connected to a limiting rod, and a top block is rotatably connected to the tooth plate and the limiting rod at one end away from the gear.

[0008] A groove is formed on the outer wall of the top block, and an anti-slip pad is fixedly assembled on the inner wall of the groove.

[0009] A through hole is formed in the top of the guide rail body, and a lifting ring is fixedly assembled on the inner wall of the through hole.

[0010] A square groove is formed in the inner wall of the guide rail body, and an auxiliary wheel is rotatably connected to the inner wall of the square groove. The number of the auxiliary wheels is several.

[0011] The limiting rod is in a shape of "匚".

[0012] The number of the toothed plates and the top blocks is two, and the two toothed plates and the top blocks are symmetrically distributed on both sides of the motor.

[0013] Compared with the prior art, the utility model has at least the following beneficial effects:

[0014] 1. In the above solution, the guide rail body is first placed into the hole, and then the motor drives the gear to rotate. The rotation of the gear drives the two toothed plates to move in opposite directions. The opposite movement of the toothed plates drives the top blocks to move. When the two top blocks abut against the hole, the top blocks will turn along with the shape of the hole until they are fixed to the inner wall of the hole. This is beneficial to reducing the labor input, facilitating the fixation of the guide rail body in a hole with a narrow diameter, and improving the adaptability of the device.

[0015] 2. In the above solution, by providing the square groove and the auxiliary wheels, it is beneficial to improve the smoothness of the robot when sliding in the guide rail body. BRIEF DESCRIPTION OF THE DRAWINGS
