Description

Connection structure of roller and roller shaft Technical Field The utility model relates to the technical field of rollers, in particular to a connecting structure of a roller and a roller shaft. Background The roller is an important consumption component for determining the efficiency of rolling mill and the quality of rolled material, and is an important part on rolling mill of steel mill, and the rolling mill steel is rolled by the pressure generated when a pair or a group of rollers roll, and is mainly affected by dynamic and static load, abrasion and temperature change during rolling. In the utility model of CN222369948U, a connection structure between a roller and a roller shaft is proposed, and researches on the prior art and the above patent find that in the existing installation of the roller and the roller shaft, a threaded rod is mostly adopted for fixing, but when the roller and the roller shaft are used for rolling a metal plate, the threaded rod may loose a movable wire, so that the roller and the roller shaft are not fixed tightly, and the use effect of the roller is affected. A connection of the roller to the roller shaft is thus proposed. Disclosure of Invention Technical problem to be solved The utility model aims to make up the defects of the prior art and provides a connecting structure of a roller and a roller shaft. The technical scheme is as follows: The roller and roller shaft connecting structure comprises a roller body and a roller shaft, wherein mounting holes are formed in two sides of the roller body, movable pin shafts are arranged in the mounting holes, insertion holes matched with the pin shafts are formed in the roller shaft, a cavity for mounting the pin shafts is further formed in the roller body, the pin shafts are inserted into the cavity, a reset spring is sleeved on the pin shafts, one end of each roller shaft is mounted in the mounting hole of the roller body, the position of each roller shaft mounted in the corresponding mounting hole can be limited through the corresponding movable pin shaft, the mounting firmness of the roller shaft is effectively improved, the phenomenon that the use effect of the roller body is affected due to looseness between the roller body and the roller shaft is avoided, the use effect of the device is effectively improved, and the practicability of the device is improved. Preferably, the mounting hole is a threaded hole, and one end of the roller shaft is in threaded connection with the inside of the mounting hole. Preferably, one end of the pin shaft is connected with a pull ring. Preferably, one end of the cavity is connected with a cover plate, and the cover plate is fixedly arranged on the roller body through a screw. Preferably, a second mounting hole for the pin shaft to pass through is formed in the cover plate. Preferably, threads are formed at the bottom of the jack, threads II are formed on the pin shaft, and the pin shaft is in threaded connection with the jack. Preferably, one end of the roll shaft is conical, and one conical end is inserted into the mounting hole. The beneficial effects are that: Compared with the prior art, the connecting structure of the roller and the roller shaft has the following beneficial effects. According to the utility model, one end of the roller shaft is arranged in the mounting hole of the roller body, the position of the roller shaft arranged in the mounting hole can be limited through the movable pin shaft, so that the mounting firmness of the roller shaft is effectively improved, the phenomenon that the use effect of the roller shaft is influenced due to looseness between the roller body and the roller shaft is avoided, the use effect of the device is effectively improved, and the practicability of the device is enhanced.
