A mechanical clamping tube for rotor shrink fit

Abstract

The invention discloses a mechanical clamping pipe for a rotor heat sleeve. Multiple circular-arc-shaped slots are formed in the outer wall of an inserting pipe. The slots are annually and uniformly distributed around the center axis of the inserting pipe. Cylindrical clamping columns are inserted into the corresponding slots of the inserting pipe. A trigger shaft is inserted into the inserting pipe. Multiple trigger grooves are formed in the outer wall of the trigger shaft and annually and uniformly distributed around the center axis of the trigger shaft. Each trigger groove is composed of a circular-arc-shaped rear groove body and a circular-arc-shaped front groove body. A transition circular arc is formed between each rear groove body and the corresponding front groove body. Each clamping column is inserted into the corresponding trigger groove. The trigger shaft is fixedly inserted to a vertical prism. The upper end of the prism is inserted into a rectangular top plate and is exposed out of the upper end face of the top plate. The top plate is fixed to the upper end of the inserting pipe. The top plate is inserted into a rectangular mounting sleeve and abuts against a limiting boss. The limiting boss is formed on the inner wall of the mounting sleeve. An end cover abuts against the lower end face of the top plate. According to the mechanical clamping pipe for the rotor heat sleeve, a rotor can be clamped conveniently in cooperation with a manipulator, and meanwhile damage to the rotor is avoided.

Description

Technical field: [0001] The invention relates to the technical field of robot manipulators, and more specifically relates to a mechanical clamping tube for thermal sleeve of a rotor. Background technique: [0002] The manipulator is an important part of the robot system. At present, in some factories, the manual operation is gradually replaced by manipulators, and the assembly and production of refrigerator compressors is also the same. In the assembly of existing refrigerator compressors, there is a process of shrinking the rotor, that is, the rotor is expanded and sleeved on the crankshaft by heating to realize Fixed connection after cooling, the existing manual operation method uses pliers to clamp the rotor to the crankshaft, but after the mechanical replacement, the use of pliers is easy to produce indentations on the rotor due to the strength problem, which affects the performance of the compressor, so other unsatisfactory methods are needed. Damage to the clamping de...
