Motor iron core stamping tool

Abstract

The invention belongs to the technical field of tool clamps, and particularly relates to a motor iron core stamping tool. The motor iron core stamping tool comprises a substrate; an electromagnetic plate is arranged above the substrate; a plane plate is mounted on the upper end face of the support panel; a driving motor is installed on the side surface of the support panel, and the output end of the driving motor penetrates through the support panel and is connected with a rotating shaft; the plane plate is provided with a mounting guide cavity, and a rotating shaft is rotationally mounted inthe mounting guide cavity; a driving gear is rotationally mounted in rotating cavities through a rotating shaft; driven gears are rotationally mounted above the rotating cavities through rotating columns; lead screw sliding blocks are slidably arranged on rotating lead screws in a sleeving and sliding mode, and the lead screw sliding blocks are slidably arranged in supporting sliding grooves formed in the side walls of the rotating cavities; arc-shaped clamping plates are fixed at the outer end parts of the lead screw sliding blocks, and the arc-shaped clamping plates are symmetrically arranged; and the bottom ends of the arc-shaped clamping plates are provided with arc-shaped supporting strips. The situation that axial rotation of a stamping workpiece to be stamped influences the stampingquality and the stamping precision of the stamping workpiece is effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of jigs and fixtures, and in particular relates to stamping jigs for motor iron cores. Background technique [0002] The motor generally includes a casing with an inner cavity, and a stator and a rotor arranged in the inner cavity of the casing. The stator core of a conventional motor is made of stacked full-circle punches with tooth grooves, and then the winding work is performed. . [0003] The motor core is the core component of the motor, which is used to increase the magnetic flux of the inductance coil and realize the maximum conversion of electromagnetic power. Stamping is an important process step in the production process of the motor core. The workpiece to be processed is clamped on the lower die, and the upper die is connected to the driving device to stamp the workpiece on the lower die to form the required shape. Auxiliary tooling is usually required in stamping and forming. [0004] However,...

Problems solved by technology

[0004] However, when the existing stamping tooling stamps the motor iron core, because the stamping workpiece 11 of the motor iron core has a circular structure, under the stamping force of the stamping device, the clamping contact surface of the stamping tooling to the stamping workpiece is too small. , which leads to the phenomenon of axial rotation of the stamping workpiece to be stamped, and at the same time causes the phenomenon of side tilting of the stamping workpiece, thereby reducing the stamping quality and stamping accuracy of the stamping workpiece
