Description

Technical Field

[0001] The present invention belongs to the technical field of linear guides, and particularly relates to a linear reciprocating motion guide rail. Background Art

[0002] In the past, in order to manufacture machines, it was necessary to separately select the methods of gear racks and linear guides to manufacture various mechanical equipment. This traditional design method requires a large amount of space and goes through multiple processing and assembly processes.

[0003] To solve these practical problems, we applied the cycloid curve principle to design the pin gear technology, integrating the linear guide and the gear rack into one whole. The prior technology chose to perform hole machining on the guide rail and use pressure to press the pins in. However, this technology will generate stress during pressing. If the guide rail is deformed or the forced adaptation adjustment management is insufficient, it may lead to the problem of pin detachment. Therefore, we added subsequent processing to solve this problem. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the present invention provides a linear reciprocating motion guide rail that can overcome or at least partially solve the above problems.

[0005] The present invention is implemented as follows. A linear reciprocating motion guide rail includes a guide rail for guiding. A slider cover is provided on the top of the guide rail. An installation hole for installation is opened inside the guide rail. The guide rail is in a 4-point R shape or V shape at a 45-degree angle, forming a linear or circular arc motion structure;

[0006] Roller parts that cooperate with the surface of the guide rail are provided at the four corners of the bottom of the slider cover;

[0007] A transmission structure for moving is provided on the top of the slider cover.

[0008] Preferably, the transmission structure includes a servo motor for power transmission. The bottom of the servo motor is detachably connected to the top of the slider cover. A transmission gear for power transmission is fixedly connected to the bottom of the servo motor. A column is meshed on the surface of the transmission gear. The bottom of the column is threadably and detachably connected to the top of the guide rail. By screwing the column into the inside of the guide rail and starting the servo motor, the servo motor drives the transmission gear to rotate. The transmission gear drives the servo motor and the slider cover to move through meshing with the column. By machining threads in the holes and holes on the guide rail and using a wrench tool for assembly, the problems of stress deformation generated during pressure forming and poor forced adaptation are solved.

[0009] Preferably, the roller member includes a guiding roller used in cooperation with the guide rail. The surface of the guiding roller is in contact and cooperation with the surface of the guide rail. A first screw is provided at the top of the guiding roller. The threaded end of the first screw penetrates through the slider cover and extends into the interior of the guiding roller, and the first screw is coaxial with the guiding roller, which can facilitate the contact and cooperation with the guide rail, and the first screw can facilitate the installation and disassembly of the guiding roller.

[0010] Preferably, the slider cover is a special-shaped part. An opening for the movement of the column is provided at the bottom of the slider cover. The surface of the transmission gear is used in cooperation with the bottom of the slider cover, which can facilitate the movement of the slider cover, and the slider cover can facilitate the installation of the servo motor and the transmission gear.

[0011] Preferably, four corners of the top of the servo motor are each provided with a second screw. The threaded end of the second screw penetrates through the servo motor and extends into the interior of the slider cover. The second screw can facilitate the installation and replacement of the servo motor.

[0012] Preferably, the slider cover is integrally formed and processed with mounting holes for installation.

[0013] Preferably, the slider cover is formed by hollow processing and processed with mounting holes for installation.

[0014] Preferably, a limiting groove for limiting is provided on the surface of the guiding roller, and the limiting groove is in snap contact with the R-shaped surface of the guide rail.

[0015] Preferably, the guiding roller is a rotor bearing, and the surface of the guiding roller is in contact and cooperation with the R-shaped surface of the guide rail.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] In order to reduce these time-consuming processes, we have developed a threaded pin bolt. By machining threads in the holes on the guide rail and in the holes, a wrench tool is used for assembly, thus solving the problems of stress deformation and poor forced adaptation generated during pressure forming.

[0018] By applying a fully sealed ball bearing or needle bearing on the linear guide rail and assembling it on the outer ring, the rotary motion of the linear guide rail is realized. At this time, the interior of the bearing is fully sealed and does not allow foreign objects to enter, and the outer ring of the bearing is in an R shape. By contacting the linear guide rail track with a small area, the friction force is minimized, and there will be no problem even if it is not lubricated for a long time.
