Device and method for enabling rotor to penetrate into exhaust end

Abstract

The invention discloses a device and method for enabling a rotor to penetrate into an exhaust end. The device comprises a manipulator and a grabbing mechanism installed at the tail end of the manipulator; the grabbing mechanism is used for grabbing an exhaust end seat; and the device also comprises a suspension workbench and a meshing driving mechanism. The meshing driving mechanism is placed on the suspension workbench; and the rotor comprises a male rotor and a female rotor which are meshed with each other. According to the device for enabling rotor to penetrate into the exhaust end providedby the invention, the male rotor and the female rotor are engaged and assembled in the mode that the male rotor and the female rotor get close to each other and rotate relatively at the same time through the meshing driving mechanism, the engagement process stability is good, collision does not exist, assembly damage is effectively reduced, and the assembly efficiency is improved.

Description

technical field [0001] The invention relates to a tooling device for piercing a rotor into an exhaust end, and also relates to a process method for piercing a rotor into an exhaust end. Background technique [0002] The screw compressor rotor spiral groove processing technology has been changed from milling cutter milling to grinding wheel grinding. The surface quality and machining accuracy of the rotor have been greatly improved, ensuring the operating efficiency of the compressor and the stability of the entire refrigeration system. [0003] At present, the rotor meshing assembly mainly relies on manual work. During the hoisting process, the hoisting force is used to achieve natural meshing. The stability of the meshing process is poor. Unstable hoisting will cause rotor collisions, damage the profiled surface, and affect the operating efficiency of the compressor. [0004] On the other hand, the surface of the bearing bush of the exhaust end seat is mostly coated with Ba...

Problems solved by technology

However, due to the low hardness of the coating, a slight collision can cause damage, and special protection is required

However, in the process of manually hoisting the rotor into the bearing pad of the exhaust end seat, it is difficult to ensure that the rotor does not collide with the bearing pad due to the shaking of the hoisting and the inertia of the rotor, which will damage the bearing pad and affect the operation of the compressor.
