Abstract

The invention discloses a rotor shaft press-fitting die. The rotor shaft press-fitting die comprises a lower die body (1) and an upper die body (2), wherein the lower die body (1) comprises a die sleeve (101) and a supporting column (102) arranged in the die sleeve (101), the upper portion of the die sleeve (101) is open, the supporting column (102) is arranged vertically upward, an insertion hole (103) which extends axially is formed in the upper end face of the supporting column (102), the upper end face of the upper die body (2) is connected with a connecting base (3) connected with a press machine, an annular groove (201) and a blind hole (202) are formed in the lower end face of the upper die body (2), the annular groove (201) and the blind hole (202) are formed coaxially, and the blind hole (202) and the insertion hole (103) are formed coaxially. According to the rotor shaft press-fitting die, a rotor shaft cannot be bent when the rotor shaft is pressed in a shaft hole in a rotor.

Description

Technical field [0001] The invention relates to a rotor shaft press-fitting mould. Background technique [0002] In the manufacturing process of the motor, there is a process of assembling the rotor shaft into the shaft hole of the rotor. At present, the rotor shaft is generally pressed into the shaft hole of the rotor by a press. After the rotor shaft is pressed into the shaft hole, The rotor shaft and the rotor achieve an interference fit. At present, when the rotor shaft is press-fitted by a press, the rotor shaft is easily bent and deformed, which will affect the normal use of the rotor shaft after the assembly is completed. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a rotor shaft press-fitting die that prevents the rotor shaft from bending and deforming when the rotor shaft is press-fitted into the shaft hole of the rotor. [0004] To solve the above technical problems, the present invention provides a rotor shaf...
