Description

Technical Field

[0001] The utility model relates to the technical field of slide blocks, in particular to a wear-resistant slide block of a machine tool. Background Art

[0002] A general-purpose machine tool is a machine tool that moves and rotates along a straight line in a coordinate system. During the movement of the coordinate system, the friction between it and the coordinate guide rail has been a shortcoming so far. The original machine tools were: a cast iron body attached to the surface of a quenched cast iron guide rail for sliding. Although one of them has high hardness and the other has a certain wear resistance, they still wear out quickly during frequent movement. The internal wear-resistant slider is on a specially customized guide rail, and a slider with balls or rollers is installed, which slides on the guide rail in a rolling manner, greatly reducing the friction coefficient during machine operation.

[0003] When the traditional wear-resistant slider of a machine tool is in operation, the wear-resistant slider will be pressed tightly, causing the entire slider to stick to the machine tool, resulting in increased friction between the entire slide. At the same time, during the processing of parts, when the slider slides continuously on the slide rail, the long-term contact between the slider and the slide rail will reduce the wear resistance of the slider, thereby affecting the accuracy of part processing. Therefore, it is necessary to design and modify the wear-resistant slider of the machine tool to effectively prevent the phenomenon of poor wear resistance. Utility Model Content

[0004] In order to solve the problems raised in the above-mentioned background technology, the purpose of the utility model is to provide a wear-resistant slider of a machine tool, which has the advantage of strong wear resistance and solves the problem that the wear-resistant slider of a traditional machine tool will be pressed when the machine tool is working, causing the entire slider to stick to the machine tool, resulting in increased friction between the entire sliding. At the same time, during the processing of parts, when the slider slides continuously on the slide rail, the long-term contact between the slider and the slide rail will cause the friction to reduce the wear resistance of the slider, thereby affecting the accuracy of part processing.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant slider of a machine tool, comprising a track, a guide rail is fixedly connected to the top of the track, a support frame is arranged on the top of the track, an oil storage box is fixedly connected to the top of the support frame, a compression spring is fixedly connected to the bottom of the inner wall of the support frame, a guide rod frame is fixedly connected to the bottom of the compression spring, the top of the guide rod frame extends to the inside of the oil storage box, a roller is movably connected to the inside of the guide rod frame, the roller is movably connected to the guide rail, electromagnets are fixedly connected to both sides of the bottom of the inner wall of the support frame, and iron plates are fixedly connected to both sides of the bottom of the track.

[0012] 2. The utility model provides a disc and a sealing ring.
