Description

Technical Field

[0001] The utility model relates to the technical field of linear slide rails, in particular to a wear-resistant slide rail which is beneficial to improving stability. Background Art

[0002] Linear guides can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are tools used to support and guide moving parts to make reciprocating linear motion in a given direction. During the sliding process, the slide cooperates with the slide rail. The slide plays the role of load and bearing to install the mechanism that needs to be moved. Therefore, the connection between the slide and the guide rail must ensure the load-bearing performance while considering the stability and friction of the installation.

[0003] In the prior art, lubricating oil is usually used to reduce the friction between the slider and the guide rail, and the position of the slider is fixed by bolts and the like. There are also methods to solve the friction problem by setting a wear-resistant layer. For example, in a self-compensating linear slide provided in patent number CN219774606U, a wear-resistant sheet is provided to solve the friction problem between the slider and the guide rail, and a spring is provided between the wear-resistant block and the slider to improve the stability of the slider. However, the spring is prone to greatly reduce or lose its elastic force over time. Once the spring is damaged during use and is not discovered in time, it is very likely to cause the slider to tilt. And the size of the spring needs to be specifically set according to the scale of the slide rail, so the production cost is high and it is not conducive to production. Summary of the invention

[0004] In view of this, the utility model provides a wear-resistant linear slide rail which can solve the above problems and is beneficial to improving stability.

The plug-in column matches the cylindrical hole and is inserted into the cylindrical hole, and the limiting edge matches and is engaged with the limiting groove to fix the lateral position of the wear-resistant sheet.

[0006] Furthermore, the adjusting member accommodating hole is communicated with the wear-resistant sheet connecting port, and a threaded structure is provided on the side wall of the adjusting member accommodating hole.

[0007] Furthermore, the cross-section of the wear-resistant sheet body is C-shaped to fit the contact surface between the slider body and the slide rail.

[0008] Furthermore, the plug-in column includes a plug-in column body, a groove formed on the plug-in column body, and a convex ring disposed at one end of the plug-in column body.

[0018] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the present invention here is not intended to limit the protection scope of the present invention.

[0019] like Figures 1 to 4As shown, it is a schematic diagram of the structure of a wear-resistant linear slide rail that is beneficial to improving stability provided by the utility model. The wear-resistant linear slide rail that is beneficial to improving stability includes a guide rail 10, a slider 20 arranged on the guide rail 10, a wear-resistant sheet 30 arranged between the guide rail 10 and the slider 20, and an elastic adjustment member 40 arranged on the slider 20 and abutting against the wear-resistant sheet 30. It is conceivable that the wear-resistant linear slide rail that is beneficial to improving stability should also include some other functional components, such as fasteners, connectors, drive mechanisms, etc., which are all technologies well known to those skilled in the art and will not be described one by one here.

[0020] The guide rail 10 may be an I-shaped linear guide rail. The guide rail 10 is fixed to a workbench or a machine such as a machine tool by fasteners such as bolts. The guide rail 10 itself is prior art and will not be described in detail here.

[0021] The slider 20 includes a slider body 21, a guide rail access port 22 disposed on the slider body 21, and at least two connection ports 23 disposed on the side walls of the slider body 21. It is conceivable that the slider 20 is also provided with screw holes for connecting products or other components to be transported, which is a technology well known to those skilled in the art and will not be described in detail here.

[0022] The slider body 21 may be a rectangular block structure, and is slidably disposed on the guide rail 10 through the guide rail access port 22 to slide.

[0023] The shape of the guide rail access port 22 matches the shape of the guide rail 10 and is an I-shaped connection port for sleeve-mounting the slider 20 on the guide rail 10 .

[0024] Each of the connection ports 23 includes a wear-resistant sheet connection port 231 disposed on a side wall of the slider body 21 close to the guide rail 10 , and an adjustment member receiving hole 232 disposed at an end of the wear-resistant sheet connection port 231 facing away from the guide rail 10 .

[0025] The wear-resistant sheet connection port 231 includes a cylindrical hole 2311 opened on the side wall of the slider body 21 along a length direction perpendicular to the slider body 21, and a limiting groove 2312 arranged at one end of the cylindrical hole 2311 close to the guide rail 10. The size of the cylindrical hole 2311 matches the plug-in column 32 in the wear-resistant sheet 30, so as to be used to install the wear-resistant sheet 30 on the slider body 21. The limiting groove 2312 and the cylindrical hole 2311 are arranged in a T shape, that is, the limiting groove 2312 is vertically connected to the plug-in column 32, so as to limit the position of the wear-resistant sheet 30 along the moving direction of the slider 20, thereby improving the connection stability of the wear-resistant sheet.

[0026] The adjusting member receiving hole 232 is communicated with the wear-resistant sheet connection port 231 to accommodate the elastic adjusting member 40. A threaded structure is provided on the side wall of the adjusting member receiving hole 232 to facilitate fixing the elastic adjusting member 40 with threaded fasteners such as bolts.

[0027] Two wear-resistant sheets 30 are respectively arranged on one side of each slider 20. The wear-resistant sheet 30 includes a wear-resistant sheet body 31, a plug-in column 32 arranged on one side of the wear-resistant sheet body 31, and a limiting edge 33 arranged at one end of the plug-in column 32 connected to the wear-resistant sheet body 31.

[0028] The wear-resistant sheet body 31 is disposed between the slide rail 10 and the slider 20 and is made of hard wear-resistant material, such as hard plastic, etc. The cross section of the wear-resistant sheet body 31 is C-shaped to fit the contact surface between the slider body 21 and the slide rail 10 .

[0029] One end of the plug-in column 32 is fixedly connected to the wear-resistant sheet body 31 , and the other end is inserted into the wear-resistant sheet connection port 231 .

[0030] The plug-in column 32 includes a plug-in column body 321 , a groove 322 formed on the plug-in column body 321 , and a convex ring 323 disposed at one end of the plug-in column body 321 .

[0031] The plug-in column body 321 is cylindrical and is inserted into the wear-resistant sheet connection port 231 to fix the wear-resistant sheet body 31 .

[0032] The groove 322 is provided on one side of the plug-in column body 321 close to the elastic adjusting member 40, and the end of the plug-in column body 321 close to the elastic adjusting member 40 is split into two halves. Since the wear-resistant sheet 30 is made of a hard material as a whole, the side of the plug-in column 32 divided into two halves by the groove 322 approaches each other when subjected to force, so that one end of the plug-in column 32 can shrink, that is, the radius of the plug-in column 32 becomes smaller and is easy to insert into the wear-resistant sheet connection port 231. When the plug-in column 32 is inserted into the wear-resistant sheet connection port 231, the wear-resistant sheet 30 is fixed on the slider 20 due to the effect of tension.

[0033] The convex ring 323 is arranged at the end of the plug-in column 32 close to the elastic adjustment member 40. The convex ring 323 is truncated cone-shaped, that is, the bottom diameters of the two ends of the convex ring 323 are inconsistent. The bottom radius of the end of the convex ring 323 close to the elastic adjustment member 40 is smaller than the bottom radius of the end connected to the plug-in column body 321, and the bottom radius of the side of the convex ring 323 connected to the plug-in column body 321 is larger than the radius of the plug-in column body 321. Therefore, the side of the convex ring 323 of the truncated cone structure forms an introduction surface, so that the plug-in column 32 can be more easily inserted into the wear-resistant plate connection port 231. At the same time, the side of the convex ring 323 with a large radius also forms a clamping ring at one end of the plug-in column body 321, so that the plug-in column is clamped in the wear-resistant plate connection port 231.

[0034] The limiting edge 33 is arranged on the wear-resistant plate body 31 perpendicular to the plug-in column 32, and matches the limiting groove 2312 so as to be clamped in the limiting groove 2312 to fix the position of the wear-resistant plate 30 perpendicular to its movement direction to prevent the wear-resistant plate 30 from being displaced due to force.

[0035] The number of the elastic adjusting members 40 matches the number of the wear-resistant sheets 30. They are accommodated in the adjusting member accommodation holes 232 and abut against the plug-in columns 32. Their positions are adjusted by fasteners such as bolts to adjust the tightness of the connection between the wear-resistant sheets 30 and the guide rail 10. The elastic adjusting members 40 can be made of polyurethane and have a round shape that matches the adjusting member accommodation holes 232. Polyurethane has excellent properties such as wear resistance, high mechanical strength, high elasticity, aging resistance and corrosion resistance. The main material used as the elastic adjusting member 40 here makes the connection between the slider 20 and the guide rail 10 more stable and durable. And the production cost is low and easy to make.

[0036] Compared with the prior art, the utility model provides a linear slide rail that is beneficial to improving stability, including the slide rail 10, the slider 20, the wear-resistant sheet 30, and the elastic adjustment member 40. The connecting port 23 is provided on the side wall of the slider 10. The connecting port 23 includes the wear-resistant sheet connecting port 231 and the adjustment member receiving hole 232. The cylindrical hole 2311 and the limiting groove 2312 of the wear-resistant sheet connecting hole 231 are arranged perpendicular to each other, and are matched and connected with the plug-in column 32 and the limiting edge 33 of the wear-resistant sheet 30, so as to fix the wear-resistant sheet 30 on the slider 20 from different directions. At the same time, an elastic adjustment member 40 is provided in the adjustment member receiving hole 232 to abut against the wear-resistant sheet 30 to adjust the tightness of the connection between the wear-resistant sheet 30 and the slide rail 10. In summary, the linear slide rail that is beneficial to improving stability is combined with the connection port 23 with a special structure on the slider 10 and the structure of the plug-in column 32 and the limiting edge 33 of the wear-resistant sheet 30, so that the wear-resistant sheet 10 and the slider 20 form a reliable and easy-to-install and replace plug-in connection. The elastic adjustment member 40 is used to adjust the distance between the wear-resistant sheet 30 and the slide rail 10, and maintain elastic stability. Compared with the spring, the elastic adjustment member 40 made of polyurethane has higher stability, is more durable and easy to make, and has a lower production cost.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent replacement or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
