Stator and casing stamping tool

Abstract

The invention discloses a stator and casing stamping tool, which comprises a base for placing a casing, wherein the base comprises an upper base plate, a lower base plate, a centering sleeve matched with a centering post and a pressure plate; the lower base plate is arranged in parallel to the upper base plate; the upper base plate is connected with the lower base plate through a plurality of connecting posts; the upper base plate is in a circular shape; the circular shape comprises an inner circle, an outer circle and a circular part between the inner circle and the outer circle; the inner circle is provided with a step for locating the casing; the circular part is provided with a plurality of top posts; the center of the lower base plate is vertically provided with the centering post; the pressure plate is arranged vertically to the centering sleeve; and the top posts limit up-and-down action of the pressure plate. According to the stator and casing stamping tool, the preliminary fixing difficulty is reduced through coordination of the centering post and the centering sleeve and arrangement of the structures of the pressure plate sleeving the outside of the centering sleeve and the like; the installation efficiency is improved; the stator and casing stamping tool can meet the coaxiality requirement of a stator and the casing and the quality of a product is ensured.

Description

technical field [0001] The invention relates to a punching tool for a stator casing. Background technique [0002] At present, the assembly of the stators of some small motors and the casings set on their periphery is completed by ordinary stamping equipment and corresponding tooling. The stamping tooling generally includes a base for fixing the casing and a pressure plate for contacting the stamping equipment. Since the casing and the stator are initially fixed manually and then put into the tooling for stamping, if the initially fixed stator and the machine If the casing is relatively inclined, the coaxiality between the stamped stator and the casing will also deviate, and the installation quality cannot be guaranteed. Therefore, it is necessary to artificially coincide the axis of the stator and the casing during the initial fixation, which is difficult to install and efficient. Low.
