Description

Technical Field

[0001] The utility model relates to the technical field of slide rails, in particular to a stable and smooth guide rail structure. Background Art

[0002] Linear guide rails include ball guide rails, roller guide rails, etc. Their function is to support and guide components. In order to improve the stability of the guide rail during operation and reduce the wear of component mating, the common practice is to add wear-resistant parts on the slide seat. For example, the Chinese utility model patent with the application number 201821605533.2 and the name of slide seat structure. However, the existing such guide rail structures have the disadvantage of poor stability when applied to high-speed guide rails. After long-term use, component wear will occur, resulting in a gap between the wear-resistant parts and the track, reducing the smoothness of the guide rail operation, lowering the work efficiency, and increasing the component replacement cost. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a stable and smooth guide rail structure.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a stable and smooth guide rail structure, including:

[0005] A track, provided with a guiding groove and supporting grooves with an arc-shaped cross-section located on both sides of the opening of the guiding groove;

[0006] A slider, sleeved on the track;

[0007] A wear-resistant strip, detachably connected to the slider. The wear-resistant strip is provided with a guiding boss and supporting arc surfaces located on both sides of the guiding boss. The guiding boss is slidably connected to the guiding groove. A strip-shaped through hole is provided on the surface of the guiding boss facing the bottom of the guiding groove. The supporting arc surfaces are slidably connected to the supporting grooves.

[0008] Further, the guiding boss is provided with an assembly plane and supporting planes located on both sides of the assembly plane. The supporting arc surfaces are located on one side of the supporting planes.

[0009] Further, there is a gap between the assembly plane and the bottom of the guiding groove. The supporting planes are slidably connected to the side walls of the guiding groove.

[0010] Further, the slider is provided with a positioning boss, and the wear-resistant strip is detachably connected to the positioning boss.

[0011] Further, the wear-resistant strip is provided with a positioning groove for clamping with the positioning boss.

[0012] Further, a positioning hole is provided on the positioning boss, and a positioning post for plugging and matching with the jack is provided in the positioning groove.

[0013] Further, an internal thread is provided on the inner wall of the end of the positioning hole away from the positioning post. The internal thread cooperates with a fastener for pressing the positioning post.

[0014] Further, two or more positioning posts are arranged at intervals along the direction parallel to the track.

[0015] Further, there is a gap between the slider and the track.

[0016] Further, limiting plates are provided on both sides of the slider along the direction parallel to the track, and the limiting plates are used to limit the wear-resistant strip.

[0017] The beneficial effects of the present utility model are as follows: A stable and smooth guide rail structure. Guide grooves are designed on two side surfaces of the track and support grooves are located on the upper and lower sides of the guide grooves. The wear-resistant strip installed on the slider is provided with guide bosses and support arc surfaces. During assembly, the guide bosses are correspondingly assembled with the guide grooves, and the support arc surfaces on both sides of the guide bosses are in contact and cooperation with the two support grooves. The guide bosses and the support arc surfaces together form a sliding connection pair to connect the wear-resistant strip and the track. The guide bosses play a main supporting role, and the support arc surfaces on both sides perform auxiliary limiting from both sides respectively. Due to the adoption of the arc surface matching design, on the one hand, the acting forces of the track on the wear-resistant strip in multiple directions can be well distributed and offset, thereby ensuring the stability during the operation of the guide rail, improving the smoothness of the component sliding, reducing the wear of the wear-resistant strip, avoiding the generation of gaps between the wear-resistant part and the track, improving the work efficiency, and saving the component replacement cost. On the other hand, the bar-shaped through-hole structure can reduce the probability of dust and impurities depositing in the guide rail chute, ensure the fitting accuracy, and is also beneficial to improving the operation stability of the guide rail and extending the service life of the component.

[0031] As can be seen from the above description, the beneficial effects of the present utility model are as follows: A stable and smooth guide rail structure, with a guide groove 11 designed on two sides of the rail 1 and support grooves 12 located on the upper and lower sides of the guide groove 11. The wear-resistant strip 3 installed on the slide block 2 is provided with a guide boss 31 and support arc surfaces 32. During assembly, the guide boss 31 is correspondingly assembled with the guide groove 11, and the support arc surfaces 32 on both sides of the guide boss 31 are in contact and cooperation with the two support grooves 12. The guide boss 31 and the support arc surfaces 32 together form a sliding connection pair to connect the wear-resistant strip 3 and the rail 1. The guide boss 31 plays a main supporting role, and the support arc surfaces 32 on both sides perform auxiliary limiting from both sides. Due to the arc surface matching design, on the one hand, the acting forces of the rail 1 on the wear-resistant strip 3 in multiple directions can be well distributed and offset, thereby ensuring the stability during the operation of the guide rail, improving the smoothness of the component sliding, reducing the wear of the wear-resistant strip 3, avoiding the generation of gaps between the wear-resistant part and the rail 1, improving work efficiency, and saving the cost of component replacement. On the other hand, the strip-shaped through hole structure can reduce the probability of dust and impurities depositing in the guide rail chute, ensure the fitting accuracy, and is also beneficial to improving the operation stability of the guide rail and extending the service life of the components.

[0032] In an alternative embodiment, the guide boss 31 is provided with an assembly plane 311 and support planes 312 located on both sides of the assembly plane 311. The support arc surface 32 is located on one side of the support plane 312.

[0034] In an alternative embodiment, there is a gap between the assembly plane 311 and the bottom of the guiding groove 11, and the supporting plane 312 is slidably connected to the side wall of the guiding groove 11.

[0035] As can be seen from the above description, one way is that it is not necessary for the assembly plane 311 to contact the bottom of the guiding groove 11. Such a design is beneficial to ensuring that the supporting plane 312 and the supporting groove 12 are in close contact with the wear-resistant strip 3, thereby improving the stability and smoothness of the guide rail operation.

[0040] In an alternative embodiment, a positioning hole 22 is provided on the positioning boss 21, and a positioning post 34 that is inserted and matched with the insertion hole is provided in the positioning groove 33.

[0043] As can be seen from the above description, by screwing the fastener into the positioning hole 22 to press against the positioning post 34, the insertion length of the positioning post 34 in the positioning hole 22 can be controlled, so as to adaptively press the wear-resistant strip 3 against the track 1.

[0044] In an alternative embodiment, two or more positioning posts 34 are arranged at intervals along the direction parallel to the track 1.

[0045] As can be seen from the above description, designing multiple positioning posts 34 can ensure the tightness of the assembly of the wear-resistant strip 3 and the track 1, and improve the running stability.
