Problems solved by technology

However, since both the male rotor 13 and the female rotor 14 are heavy in weight, there are inconvenient operations and potential safety hazards during the hoisting process. At the same time, workers are required to continuously adjust the rotor angle during the meshing assembly process, which is inefficient and has large errors.
In addition, the coating on the surface of the bearing bush of the exhaust end seat 1 can form an oil film with the rotor, which can effectively protect the rotor. However, due to the low hardness of the coating, a slight collision can cause damage, and protection is required; while the manual hoisting rotor penetrates During the process of the exhaust end seat 1 bearing bush, due to hoisting shaking, rotor inertia, etc., it is difficult to ensure that the rotor does not collide with the bearing bush, damage the bearing bush, and affect the operation effect of the compressor

Abstract

The invention relates to the technical field of screw compressors, in particular to a special assembling machine for a large screw-type rotor. According to the technical scheme, the special assembling machine comprises a bearing plate, the lower side of the bearing plate is fixedly connected with supporting legs, a two-rotor automatic meshing device, an exhaust end base bearing device and a special machine data processing center are arranged on the upper side of the bearing plate, and the two-rotor automatic meshing device can move in the direction close to the exhaust end base bearing device so that assembling of two rotors and an exhaust end base can be conveniently completed; the exhaust end base bearing device comprises a lifting plate which ascends and descends in the vertical direction, and a positioning piece for positioning the exhaust end base on the lifting plate is arranged on the lifting plate; and the lifting plate is further provided with two machine vision cameras which are respectively used for scanning and shooting the end surfaces of the two rotors, collecting information and transmitting data to the special machine data processing center. The special assembling machine has the advantages that the accuracy in an assembling process of the two rotors is improved, and the assembling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of screw compressors, in particular to a special machine for assembling large screw rotors. Background technique [0002] Screw compressors, also known as screw compressors, are widely used in refrigeration devices such as refrigeration, refrigeration, air conditioning, and chemical processes due to their simple structure, few wearing parts, and good air volume adjustment. The screw compressor cylinder is equipped with a pair of parallel and intermeshed screw type male rotor and female rotor. Both rotors have several concave teeth, and the concave teeth of the two rotors rotate in opposite directions. The gap between the two rotors and between the casing and the rotor is only 5 to 10 wires. The main rotor (also known as male rotor or convex rotor) is driven by an engine or an electric motor (mostly driven by an electric motor), and the other rotor (also known as a male rotor) is driven by an electric motor. ...
