Problems solved by technology

In order to ensure the efficiency of the motor, a small air gap design is used between the rotor and the stator when designing the motor. Due to the high viscosity of the magnetic tile glue, there is a certain thickness after the glue is cured. When the thickness is uneven or too thick, it will cause Scratches between the rotor and the stator, resulting in increased load or seizure, which can lead to ablation damage to the motor

Abstract

The invention discloses a semi-automatic magnetic tile tensioning device, comprising a positioning plate and a tensioning mechanism. The tensioning mechanism includes a bottom plate, a guide seat, a positioning base, a locking block, a cylindrical pin, an elastic reset device and an upper die. The seat is sleeved on the upper part of the guide seat, the upper end of the guide seat is provided with an outer conical part, the inside of the positioning base is provided with a second circular hole at a corresponding position, and the outer side wall of the upper end of the second circular hole is provided with N square holes that are evenly distributed around the circumference. A locking block is inserted into the square hole, which can be connected with the square hole to move along a radial line. The inner side of the locking block is provided with an inner conical arc surface that matches with the outer conical part. The elastic reset device is arranged on the positioning base and the guide. between seats. In the present invention, the press drives the upper die to go down, the upper die drives the workpiece and the positioning base to go down together, drives a plurality of locking blocks to move downward and outward at the same time, and tensions the corresponding magnetic tiles, which ensures the uniform thickness of the glue and improves the magnetic properties. The bonding strength of the tile can effectively avoid the phenomenon of scratching between the rotor and the stator.

Description

technical field [0001] The invention relates to the technical field of brushless motor installation, in particular to a semi-automatic magnetic tile tensioning device. Background technique [0002] The brushless motor rotor assembly is a rotating part, which is mainly used as the rotor of the motor to transmit mechanical energy. The magnetic tile installation process of the brushless motor rotor assembly is to coat the surface of the magnetic tile with one-component resin glue, then install it into the rotor housing, and locate it by the polarities of the positioning brackets. In order to ensure the efficiency of the motor, a small air gap design is used between the rotor and the stator in the motor design. Due to the high viscosity of the magnetic tile glue, there is a certain thickness after the glue is cured. When the thickness is uneven or too thick, it will lead to The rotor and the stator are scratched, resulting in increased load or stuck, which can lead to ablation ...
