Pass-type rotor heating furnace for piston compressor

Abstract

The purpose of the invention is to provide a pass-type rotor heating furnace, comprising a rack, wherein at least two chain wheels are mounted on the rack and connected through a bent plate chain; an induction heating furnace is arranged on the rack; the bent plate chain passes through the interior of the induction heating furnace; a work fixture is arranged on the bent plate chain; and a motor is arranged below the chain wheel on the right side and drives the chain wheels to rotate. A rotor is heated through the induction heating furnace arranged on the rack and is placed on the work fixture on the bent plate chain, the chain is driven by the chain wheels to rotate, the heating time of the rotor in the induction heating furnace is further controlled; moreover, a temperature detector is arranged, the motor and a chain expansion mechanism are controlled so that the heating time of the rotor which is not completely heated is prolonged; therefore, the work efficiency is improved, the work time is reduced and the work intensity is reduced.

Description

technical field [0001] The invention relates to a heating device for a piston type refrigerating compressor, in particular to a type of rotor heating furnace through which the rotor of the piston type compressor is shrunk through. Background technique [0002] When installing the rotor in the original piston compressor, it is necessary to make the rotor and the long axis of the crankshaft carry out an interference fit, but the rotor cannot be installed on the long axis with the general installation method. Therefore, it is necessary to heat the rotor to expand it when heated, and then install the heated rotor into the long axis of the crankshaft through a positioning fixture to achieve the effect of interference fit. However, when the rotor is heated at present, it is usually installed on both sides of the heating furnace with a certain slope raceway, so that the rotor rolls down by itself under the action of gravity, which will easily cause the outer circle of the rotor to ...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a through-type heating furnace for heating the rotor. The rotor is heated separately through the fixture on the chain, and the sprocket is controlled by controlling the motor speed, so that the rotor can control the rotation rhythm of the heating furnace to achieve control The heating time of the rotor solves the problems that the rotor is easily damaged during heating, uneven heating and stuck in the heating furnace, and the heating time is controllable.
