Abstract

The invention belongs to the field of ultrasonic vibration and mechanical engineering, and discloses an interference fit part assembling and disassembling device applying ultrasonic vibration and a using method. The interference fit part assembling and disassembling device comprises a press, an ultrasonic generation device, a sleeve mechanism and a vibration mechanism, wherein the press is a mechanical press with lifting threads, the ultrasonic generation device is connected with the sleeve mechanism through a flange plate by using bolts, the vibration mechanism is connected with the sleeve mechanism through a lower end cover and a flange plate by using bolts, a bottom cross beam is arranged at the bottom of a device body, and a fastening seat is arranged on the bottom cross beam. According to the interference fit part assembling and disassembling device applying ultrasonic vibration and the using method, the press-fitting force during assembling and the pressure value required duringdisassembling are effectively reduced, the damage to the contact surface of a part is reduced, the working efficiency and the operation safety are improved, and the labor intensity is reduced.

Description

technical field [0001] The invention belongs to the field of ultrasonic vibration and mechanical engineering, and relates to an assembly and disassembly device and a use method of an interference fit part applying ultrasonic vibration. Background technique [0002] Interference fit is widely used in shaft components of mechanical structures because of its high positioning accuracy, strong bearing capacity, and simple and reliable structure. Interference fit parts are generally assembled by temperature difference method and press-in method. The temperature difference method uses the principle of thermal expansion and contraction. The temperature difference method is suitable for assembly with large interference; the press-in method is to directly press shaft parts into the hole. Among the parts, the press-in method is suitable for the assembly of small interference. During the assembly process of the traditional press-in method, the mating surface of the parts will be scratc...

Problems solved by technology

During the assembly process of the traditional press-in method, the mating surface of the parts will be scratched, which will affect the assembly quality

It is relatively difficult to disassemble the interference fit parts. At present, the mechanical disassembly method and the temperature difference disassembly method are often used, but the two operation methods are time-consuming and labor-intensive, and there are certain risks.
