Description

Technical Field

[0001] The utility model relates to the field of mechanical component manufacturing, in particular to an adjustable wear-resistant sliding block. Background Art

[0002] A slider is a mechanical component, usually composed of a flat or convex component (slider body) and a guide component (such as a guide rail) that slides it. The main function of the slider is to provide linear motion or cycloidal motion in mechanical movement, and to bear loads and reduce friction. Sliders are mainly used in mechanical engineering, automotive industry, shipbuilding industry, aircraft manufacturing, electronic appliances and other fields to control the direction and speed of movement, and to achieve functions such as movement, support and positioning of mechanical parts. The installation method of the slider will vary depending on the specific application scenario and requirements. It can generally be fixed to a specific part of the machine by bolts or nuts. When installing the slider, pay attention to the correct position, angle and direction to ensure its normal operation. The connection accuracy and friction between the slider and the guide rail are one of the main reasons that affect the normal operation of the slider.

[0003] In the prior art, the friction problem between the slider and the guide rail is usually solved by adding a wear-resistant component between the slider and the guide rail. For example, in a self-compensating linear slide provided in Patent No. CN219774606U, a wear-resistant block is added between the slider and the guide rail to prevent direct contact and friction between the slider and the guide rail, and at the same time, a spring is set to enable dynamic adjustment between the slider and the guide rail. The wear-resistant block often needs to be specially designed according to different sliders and is not universal, and the connection between the wear-resistant sheet and the slider is often difficult to achieve high precision. Once the wear-resistant sheet is displaced or falls off during operation, it is easy to affect the connection between the slider and the guide rail. At the same time, the service life of the spring is short. When the spring on one side of the slider fails, the spring force on the other side can easily cause the slider to deviate from the track. Summary of the invention

[0004] In view of this, the utility model provides an adjustable wear-resistant sliding block which can solve the above-mentioned problem.

[0005] An adjustable wear-resistant slider includes a slider body and at least one guide rail connecting part arranged on the slider body. Each guide rail connecting part includes a connecting part body, a connecting groove arranged on the side of the connecting part body facing the guide rail, and at least one wear-resistant layer unit fixedly connected to the connecting groove.

The sintered layer and the wear-resistant layer body are both the same as the outer contour of the connecting groove, so that the wear-resistant layer unit is stably fixed in the connecting groove and protects the connecting groove.

[0006] Furthermore, the adjustable wear-resistant sliding block also includes at least one adjustment unit arranged on the guide rail connecting part, the adjustment unit includes an adjustment piece and an adjustment piece connecting port for setting the adjustment piece, the adjustment piece includes an adjustment nut and an adjustment block fixedly connected to one end of the adjustment nut, the adjustment piece connecting port includes a screw hole arranged on the connecting part body, and a clearance groove arranged at one end of the screw hole, the adjustment nut is threadedly connected to the screw hole, and the adjustment block is fixedly connected to the adjustment nut and accommodated in the clearance groove.

[0007] Furthermore, the connecting portion body is integrally provided with the slider body, and the length of the connecting portion body is equal to the length of the slider body.

[0008] Furthermore, the thickness of a side of the connecting portion body connected to the slider body is greater than the thickness of the slider body.

[0009] Furthermore, the outer contour of the connecting groove may be U-shaped or C-shaped.

[0010] Furthermore, the connection groove is arranged on a side of the connection part body facing the guide rail.

[0020] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the present invention herein is not intended to limit the protection scope of the present invention.

[0021] Embodiment 1:

[0022] like Figure 1 As shown, it is a schematic structural diagram of a first embodiment of an adjustable wear-resistant slider provided by the utility model. The adjustable wear-resistant slider includes a slider body 10 and two guide rail connecting parts 20 arranged on both sides of the slider body 10. It is conceivable that the adjustable wear-resistant slider provided by the utility model should also include some other functional components, such as connecting components, driving components, etc., which are well known to those skilled in the art and will not be described in detail here.

[0023] The slider body 10 may be a rectangular plate structure. The slider body 10 may also be provided with a screw hole structure for connection. The slider body 10 itself is prior art and will not be described in detail here.

[0024] The guide rail connection part 20 is arranged on both sides of the slider body 10 along the length direction of the slider body 10. The guide rail connection part 20 includes a connection part body 21, a connection groove 22 arranged on a side of the connection part body 21 facing the guide rail, and a wear-resistant layer unit 23 fixedly connected to the connection part body 21.

[0025] The connecting part body 21 is integrally provided with the slider body 10, and its length is equal to that of the slider body 10. Connection holes should also be provided at both ends of the connecting part body 21 for setting a load-bearing object or other structure. The connection between the connecting part body 21 and the slider body 10 is not flush. That is, the thickness of the side where the connecting part body 21 is connected to the slider body 10 is greater than the thickness of the slider body 10, thereby forming an avoidance groove 211 on the side of the slider body 10 facing the guide rail to reduce the contact area between the slider and the guide rail.

[0026] The connecting groove 22 is arranged on the side of the connecting part body 21 facing the guide rail, and is used to form a sliding connection between the slider and the guide rail. The outer contour of the connecting groove 22 can be designed in a U-shape, and one side of the two sides of the U-shape serves as a load-bearing surface 221, and one side serves as a limiting surface 222. The load-bearing surface 221 is the side close to the slider body 10, and is the side of the slider used for bearing weight. The limiting surface 222 is the side away from the slider body 10, and is used to buckle with the bottom of the guide rail to install the slider on the guide rail. The width of the load-bearing surface 221 is greater than the width of the limiting surface 222, thereby increasing the load-bearing area of ​​the slider.

[0027] The wear-resistant layer unit 23 is fixedly connected in the connection groove 22. The wear-resistant layer unit 23 includes a sintered layer 231 sintered in the connection groove 22, and a wear-resistant layer body 232 disposed on one side of the sintered layer 231. The sintered layer 231 and the wear-resistant layer body 232 are both consistent with the outer contour of the connection groove 22, so that the wear-resistant layer unit 23 is stably fixed in the connection groove 22 and protects the connection groove 22.

[0028] Embodiment 2:

[0029] like Figure 2, which is a schematic diagram of the structure of the second embodiment of an adjustable wear-resistant slider provided by the utility model. The adjustable wear-resistant slider comprises a slider body 30 and a guide rail connection portion 40 arranged on both sides of the slider body 30 along the length direction of the slider body 10.

[0030] The slider body 30 is a square body structure. A plurality of screw holes for connecting a load or other objects are arranged on the slider body 30. The slider body 30 itself is a prior art known to those skilled in the art, and will not be described in detail here.

[0031] The guide rail connection part 40 is fixedly connected to the slider body 30 on one side of the slider body 30. The guide rail connection part 40 includes a connection part body 41, a connection groove 42 arranged on the connection part body 41, and a wear-resistant layer unit 43 arranged in the connection groove 42 and fixedly connected to the connection part body 41. The connection part body 41 and the connection groove 42 are integrally arranged. The connection groove 42 is a C-shaped design that fits the rail. The wear-resistant layer unit 43 is fixedly connected in the connection groove 42. The wear-resistant layer unit 43 includes a sintered layer 431 sintered in the connection groove 42, and a wear-resistant layer body 432 arranged on one side of the sintered layer 431. The sintered layer 431 and the wear-resistant layer body 432 are both consistent with the outer contour of the connection groove 42, so that the wear-resistant layer unit 43 is stably fixed in the connection groove 42 and protects the connection groove 42. It is understandable that, since the wear-resistant layer unit 43 and the connecting part body 41 are fixedly connected by a sintering process, the wear-resistant layer unit 43 is not only suitable for the connecting groove 42 of a certain shape, but can also be used between the contact surfaces of sliders and slide rails of other shapes, thereby extending the service life of the slider.

[0032] Embodiment 3:

[0033] like Figure 3 to Figure 4 , which is a schematic structural diagram of a third embodiment of an adjustable wear-resistant slider provided by the utility model. The adjustable wear-resistant slider comprises a slider body 50, two guide rail connecting parts 60 arranged on both sides of the slider body 50, and at least one adjustment unit 70 arranged on the guide rail connecting part 60.

[0034] The structure of the slider body 50 is completely consistent with that of the slider body 10 , and will not be further described herein.

[0035] The structure of the guide rail connecting portion 60 is completely consistent with that of the guide rail connecting portion 20 , and will not be further described herein.

[0036] The adjusting unit 70 includes an adjusting member 71 and an adjusting member connecting port 72 for setting the adjusting member 71 .

[0037] The adjusting member 71 includes an adjusting nut 711 and an adjusting block 712 fixedly connected to the adjusting nut 711. The adjusting nut 711 is screwed onto the guide rail connecting portion 60, and one end of the adjusting nut 711 is fixedly connected to the adjusting block 712. The adjusting block 712 can be made of a hard, wear-resistant material, such as hard plastic. Preferably, the adjusting block 712 can be a square structure.

[0038] The adjusting member connection port 72 includes a screw hole 721 disposed on the connecting portion body 21 for setting the adjusting nut 711, and a clearance groove 722 disposed at one end of the screw hole 721 for accommodating the adjusting block 712. The screw hole 721 and the clearance groove 722 are connected to each other. The extension direction of the screw hole 721 is perpendicular to the length direction of the connecting portion body 21. The clearance groove 722 is disposed on the side of the connecting portion body 21 facing the track and is centered along the length direction of the connecting portion body 21, and the clearance groove 722 passes through the limiting surface 222 along the width direction of the limiting surface 222. It can be understood that the shape of the clearance groove 722 is consistent with the shape of the adjusting block 712, and is a square body structure.

[0039] The adjusting nut 711 is threadedly connected with the screw hole 721, and the adjusting block 712 is fixedly arranged at one end of the adjusting nut 711 and accommodated in the clearance groove 722. When the adjusting nut 711 is rotated, the adjusting nut 711 pushes or withdraws the adjusting block 712, thereby fine-tuning the position of the slider, so that the connection between the slider and the slide rail is more reliable.

[0040] Compared with the prior art, the utility model provides an adjustable wear-resistant slider, which includes a slider body 10 and a guide rail connecting portion 20 arranged on the slider body 10. The guide rail connecting portion 20 includes a connecting portion body 21, a connecting groove 22 arranged on the side of the connecting portion body 21 facing the guide rail, and at least one wear-resistant layer unit 23 fixedly connected to the connecting groove 22. The wear-resistant layer unit 23 includes a sintered layer 231 sintered in the connecting groove 22, and a wear-resistant layer body 232 arranged on one side of the sintered layer. The sintered layer 231 and the wear-resistant layer body 232 are both the same as the outer contour of the connecting groove 22, so that the wear-resistant layer unit 23 is stably fixed in the connecting groove to protect the connecting groove 22. The wear-resistant layer unit 23 and the connecting groove 22 are sintered to each other, which is not only conducive to the stable connection between the guide rail and the slider, but also makes the wear-resistant layer unit 23 more versatile. Preferably, the adjusting unit 70 may be further provided on the adjustable wear-resistant sliding block to fine-tune the position of the adjustable wear-resistant sliding block, so as to further ensure the stable connection between the adjustable wear-resistant sliding block and the guide rail.
