Description

Heavy-load roller slider with improved assembly structure Technical Field The utility model belongs to the technical field of linear guide rail sliding blocks, and particularly relates to a heavy-load roller sliding block with an improved assembly structure. Background Linear guide rail sliding block mechanisms are increasingly applied to various fields in the modern mechanical industry, and demands such as high load, severe environment, high linear speed and the like are also accompanied. According to the heavy-load roller slider disclosed in the prior art, the patent publication number CN216077966U is arranged on a platform or a support through a guide rail, a roller is arranged in a long hole on the slider through a roller pin, the roller pin is fixed by a jackscrew, the roller surface is in contact with the guide rail surface, a follower is fastened in a follower hole of the slider, the follower surface is in rolling contact with the guide rail surface, the follower is divided into two groups and the axes are mutually at a certain angle to prevent the whole slider from falling off from the guide rail, the followers on the two sides of the slider are in rolling contact with the roller from three directions, the roller is in line-line contact with the guide rail, the contact area is larger, the limit load is higher, the problem that a steel ball is in dotted line contact with the guide rail, the contact area is too small, and the load is smaller still exists in practical use. Therefore, there is a need for a heavy-duty roller slider with an improved assembly structure, which solves the problems of difficult assembly and loosening risk in the operation process in the prior art. Disclosure of utility model The present utility model is directed to a heavy-duty roller slider with improved assembly structure, so as to solve the above-mentioned problems in the prior art. In order to achieve the above purpose, the heavy-duty roller slider with the improved assembly structure comprises a guide rail and a slider, wherein the slider slides on the guide rail, a mounting hole is formed in the slider, a roller is arranged in the mounting hole, a roller pin is fixedly connected to the roller, the roller pin is correspondingly arranged in the slider and provided with a pin hole, the roller pin is rotatably arranged in the pin hole, improved mechanisms are arranged on the left side and the right side of the slider and used for limiting the sliding of the slider, a jackscrew is arranged on the slider and correspondingly provided with a positioning hole, and the jackscrew is used for limiting the roller pin in the positioning hole. In the scheme, the improved mechanism comprises a needle bearing, a screw rod, a jack and a threaded hole, wherein the screw rod is arranged on the needle bearing, the jack is arranged on the sliding block in a penetrating mode, the threaded hole is arranged on the outer side of the jack, and the needle bearing is locked and limited in the jack and the threaded hole through the screw rod. It is further worth noting that the needle bearing is externally coated with a locking glue.
