Rotor support shaft-pressing tool

Abstract

The invention discloses a rotor support shaft-pressing tool. The rotor support shaft-pressing tool comprises a press machine, a pressing head and a balance end plate positioning mechanism; the press machine is provided with a supporting platform, the balance end plate positioning mechanism is arranged on the supporting platform, the balance end plate positioning mechanism is used for bearing a rotor support and a balance end plate arranged on the rotor support in a sleeved mode, the pressing head is located right above the balance end plate positioning mechanism and is connected with the pressmachine, the bottom surface of the pressing head is provided with an outer extrusion surface used for extruding the balance end plate, the outer extrusion surface acts on the balance end plate, so that the balance end plate is fixedly connected with the rotor support. The tool has the characteristics of being low in energy consumption, safe to operate, clean in field environment, reliable in quality, high in production efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of production of automobile motor rotors, and in particular relates to a tooling for finalizing a shaft of a rotor support. Background technique [0002] The rotor of the motor includes components such as a rotating shaft, an iron core, an end plate, and a commutator. The current assembly process is as follows: first heat the rotor bracket to 200 degrees Celsius in an oven, manually insert the rotating shaft into the middle hole of the rotor bracket, and position it with a key; then heat the balance end plate in the oven to at least 100 degrees Celsius, and manually insert the Put it into the rotor bracket (cooled to below 45 degrees Celsius), and adjust the position to ensure that the pin hole is concentric; finally, knock the pin into the pin hole with a copper rod to fix the position of the rotor bracket and the phase plate of the balance end plate. However, there are many defects in this method, such as...

Problems solved by technology

However, there are many defects in this method, such as heating the workpiece, which needs to consume more electric energy; the surface temperature of the workpiece is too high, which is prone to burn accidents; when the metal parts are supplied, there will be a small amount of anti-rust oil on the surface, which will generate smoke after heating. and pungent smell, so that the production site environment is very poor, affecting customer visits; there are heating and cooling links in the workpiece, which makes it difficult to achieve continuous mass production; the heat-fitting process requires a high level of experience for the operator. Manual operation, If there is a slight error, the workpiece is easily scrapped
