Clamping device for bearing assembly

Abstract

To solve the existing problem of laborious assembly of bearings, the invention discloses a clamping device for bearing assembly, comprising a connecting rod, a connecting plate, a mounting rod, a pushing block, an electric motor, a rotary table, a pushing plate, a positioning rod, a baffle plate, a coil spring, an end cap, a guide frame, an adsorption layer, a sliding tube, a heating rod, a holding cylinder, a screw, a clamping rod, a snap ring, a through hole, a pump, a water guide pipe, a positioning plate, a rotating rod, a lantern ring and a sliding block. The clamping device has the advantages of reasonable design, convenient operation, reasonable structure and simple principle of thermal expansion and cold contraction the adopted, so that the bearing is convenient to be assemble andaccords with the social demand, and is worth popularizing and using in the mechanical field.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a clamping device for bearing assembly. Background technique [0002] Bearing is an important basic component of various mechanical equipment, its precision, performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the main engine. Among mechanical products, bearings are high-precision products, which not only require the comprehensive support of mathematics, physics and many other disciplines, but also require material science, heat treatment technology, precision machining and measurement technology, numerical control technology and effective numerical methods and powerful computers. Technology and many other disciplines serve it, so the bearing is a product that represents the country's scientific and technological strength. [0003] Due to the principle of thermal expansion and contraction, when the bearing is matched with the shaft,...

AI Technical Summary

Problems solved by technology

[0003] Due to the principle of thermal expansion and contraction, when the bearing is matched with the shaft, it is not easy to assemble the bearing in cold weather, and the operator needs to use a hammer to hammer repeatedly, which is laborious and affects the quick assembly of the bearing. , we know that when the bearing is slightly deformed due to the weather, it will be very difficult to assemble, and it is not easy to add butter to the bearing during the assembly process. It is necessary to wait for the bearing to be installed before lubricating. Therefore, There is a need to design a clamping device for bearing assembly to solve the deficiencies in the prior art
