Description

Technical Field

[0001] The utility model relates to the technical field of guide rails and racks, and specifically relates to an anti-wear guide rail and rack with good stability. Background Technique

[0002] A guide rail and rack is a guiding device widely used in mechanical transmission. It mainly consists of a rack fixed on a machine frame and a guide rail fixed on a moving part. It is a transmission device that converts linear motion and rotational motion into each other. It realizes precise control of linear motion through the meshing of the teeth on the rack and the gear.

[0003] The guide rail and rack usually consists of two parts: a rack and a guide rail. The rack is a long strip-shaped part with many teeth evenly distributed on one side. The guide rail is used to support and guide the moving part to ensure its movement along a predetermined trajectory. Generally, the guide rail and the rack are of an integrated structural form. When the rack meshes and drives with the gear for a long time, it is prone to wear. After wearing to a certain extent, it needs to be replaced as a whole, which is not conducive to saving resources. And for some split-type guide rail and racks, there is a problem of insufficient connection tightness, and it is easy to loosen between the rack and the guide rail, and the stability during work is not good. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-wear guide rail and rack with good stability to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti-wear guide rail and rack with good stability, including a guide rail main body, a rack main body, teeth and fastening bolts. The rack main body is arranged on the top of the guide rail main body, and teeth are evenly distributed on the surface of the rack main body. A chromium-plated wear-resistant coating is arranged on the outside of the teeth. Reserved grooves are evenly opened at the bottom of the guide rail main body, and the inside of the reserved grooves is fixedly connected with the rack main body through fastening bolts. The bottom ends of the fastening bolts are locked and fixed through fastening nuts, and one end of each fastening nut close to the reserved groove is tightly attached to the reserved groove through a buffer cushion plate. A support member is arranged at one end of each buffer cushion plate close to the fastening nut, and a buffer member is arranged between each support member and the fastening nut.

[0006] Preferably, mounting holes are evenly distributed on the rack main body, and the mounting holes are arranged in a staggered manner with the fastening bolts.

[0007] Preferably, a cavity is opened at the central position inside the rack main body, and two groups of reinforcing plate members are arranged inside the cavity.

[0008] Preferably, a base body is arranged at the central position inside each tooth, and each base body is made of alloy steel.

[0009] Preferably, grooves are provided on the rack body between the teeth, and the cross-sections of the grooves are all semi-circular structures.

[0010] Preferably, the buffer members are all strip-shaped rubbers, and both ends of the buffer members are connected to the support members to form an arched structure.

[0011] Preferably, a hardened layer is provided on the outer side of the base body, and the hardened layer is covered on the surface of the base body by means of carburizing and quenching.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The anti-wear guide rail rack with good stability is provided with a guide rail body, a rack body, teeth, fastening bolts, reserved grooves, fastening nuts, buffer pads, support members and buffer members. The guide rail body is uniformly fixedly connected to the rack body through the fastening bolts, and one ends of the fastening bolts are fixedly locked through the fastening nuts. Reserved grooves are uniformly formed on one side of the guide rail body, so that the fastening nuts can be embedded into the reserved grooves and are not easily exposed outside to affect the use of the guide rail body. One ends of the fastening nuts close to the reserved grooves are tightly pressed and fitted to the reserved grooves through the buffer pads. The buffer members are strip-shaped rubbers, and both ends of the buffer members are connected to the support members to form an arched structure. When the fastening nuts are connected to the fastening bolts, a certain pre-tightening force is applied to the fastening bolts by using the elasticity of the rubber, thereby improving the connection stability. At the same time, the self-lubricity of the rubber material can also reduce the friction during the connection process and reduce the loosening phenomenon caused by friction.
