Description

Technical Field

[0001] The invention relates to the technical field of slide rails, and in particular to a high-speed guide rail structure. Background Art

[0002] Linear guides include ball guides, roller guides, etc., which support and guide components. In order to improve the stability of the guides during operation and reduce the wear of the components, it is common to add wear-resistant parts to the slide, such as the Chinese utility model patent with application number 201821605533.2 and the name of the slide structure. However, the existing guide structure of this type has the disadvantage of poor stability when applied to high-speed guides. After long-term use, the components will wear out, resulting in gaps between the wear-resistant parts and the track, reducing the smoothness of the guide operation, reducing work efficiency, and increasing the cost of component replacement. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a stable and smooth high-speed guide rail structure.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a high-speed guide rail structure, comprising:

[0005] A track is provided with a guide groove and arc grooves located on both sides of the opening of the guide groove;

[0006] A slider is sleeved on the track;

[0007] The wear-resistant strip is detachably connected to the slider, and is provided with a guide boss and supporting arc surfaces on both sides of the guide boss. The guide boss is slidably connected to the guide groove, and the supporting arc surface is slidably connected to the arc groove.

[0008] Furthermore, the guide boss is provided with an assembly plane and support planes located on both sides of the assembly plane, and the support arc surface is located on one side of the support plane.

[0009] Furthermore, there is a gap between the assembly plane and the groove bottom of the guide groove, and the support plane is slidably connected to the side wall of the guide groove.

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

[0011] Furthermore, the wear-resistant strip is provided with a positioning groove which is engaged with the positioning boss.

[0012] Furthermore, a positioning hole is provided on the positioning boss, and a positioning column which is plugged and matched with the plug hole is provided in the positioning groove.

[0013] Furthermore, an inner wall of the positioning hole at one end away from the positioning column is provided with an internal thread, and the internal thread cooperates with a fastener, and the fastener is used to press the positioning column.

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

[0015] Furthermore, there is a gap between the slider and the rail.

[0016] Furthermore, both sides of the sliding block along the direction parallel to the track are provided with limiting plates, and the limiting plates are used to limit the wear-resistant strips.

[0017] The beneficial effects of the present invention are: a high-speed guide rail structure, guide grooves and arc grooves located on the upper and lower sides of the guide grooves are designed on the two sides of the rail, and the wear-resistant strip installed on the sliding block is provided with a guide boss and a supporting arc surface. During assembly, the guide boss is assembled corresponding to the guide groove, and the supporting arc surfaces on both sides of the guide boss are in contact and matched with the two arc grooves. The guide boss and the supporting arc surfaces together form a sliding connection pair to connect the wear-resistant strip and the rail.

[0028] The track 1 is provided with a guide groove 11 and arc grooves 12 located on both sides of the opening of the guide groove 11;

[0029] Slider 2, sleeved on track 1;

[0030] The wear-resistant strip 3 is detachably connected to the slider 2 and is provided with a guide boss 31 and supporting arc surfaces 32 located on both sides of the guide boss 31 . The guide boss 31 is slidably connected to the guide groove 11 , and the supporting arc surface 32 is slidably connected to the arc groove 12 .

[0031] From the above description, it can be seen that the beneficial effects of the present invention are: a high-speed guide rail structure, a guide groove 11 and arc grooves 12 located on the upper and lower sides of the guide groove 11 are designed on the two sides of the track 1, and the wear-resistant strip 3 installed on the slider 2 is provided with a guide boss 31 and a supporting arc surface 32. When assembling, the guide boss 31 is assembled correspondingly with the guide groove 11, and the supporting arc surfaces 32 on both sides of the guide boss 31 are in contact with the two arc grooves 12. The guide boss 31 and the supporting arc surface 32 together form a sliding connection pair to connect the wear-resistant strip 3 and the track 1, and the guide boss 31 plays a major supporting role The supporting arc surfaces 32 on both sides are used for auxiliary limiting from both sides respectively. Due to the arc surface matching design, on the one hand, the force of the rail 1 on the wear-resistant strip 3 in multiple directions can be well distributed and offset, thereby ensuring the stability of the guide rail during operation, improving the sliding smoothness of the components, reducing the wear of the wear-resistant strip 3, avoiding the gap between the wear-resistant parts and the rail 1, improving work efficiency, and saving component replacement costs. On the other hand, it can also reduce the probability of dust and impurities being deposited in the guide rail slide groove, ensuring matching accuracy, and is also beneficial to improving the stability of the guide rail operation and extending the service life of the components.

[0032] In an optional 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 , and the support arc surface 32 is located on one side of the support plane 312 .

[0033] It can be seen from the above description that the assembly plane 311 plays a role of protection and restraint in the direction perpendicular to the groove bottom of the guide groove 11, and the support plane 312 plays a role of support and limitation in the direction parallel to the groove bottom of the guide groove 11.

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

[0035] From the above description, it can be seen that one way is to not require the assembly plane 311 to contact the bottom of the guide groove 11. This design is conducive to ensuring that the support plane 312 and the arc groove 12 are in close contact with the wear-resistant strip 3, thereby improving the stability and smoothness of the guide rail operation.

[0042] In an optional embodiment, an inner wall of the positioning hole 22 at one end away from the positioning column 34 is provided with an internal thread, and the internal thread cooperates with a fastener, and the fastener is used to press the positioning column 34 .

[0043] From the above description, it can be known that by screwing the fastener into the positioning hole 22 to press against the positioning column 34 , the insertion length of the positioning column 34 in the positioning hole 22 can be controlled, so that the wear-resistant strip 3 can be adaptively pressed onto the rail 1 .

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

[0045] It can be seen from the above description that designing a plurality of positioning posts 34 can ensure the tightness of the assembly between the wear-resistant strip 3 and the rail 1 and improve the stability of the operation.

[0046] In an alternative embodiment, there is a gap between the slider 2 and the rail 1 .
