Description

Technical Field

[0001] The utility model belongs to the technical field of linear motors, and in particular relates to a high-precision thrust linear motor capable of automatic correction and installation. Background Art

[0002] A linear motor is a transmission device that converts electrical energy directly into linear motion without any intermediate conversion mechanism. It can be thought of as a rotary motor cut radially and flattened into a flat surface. Linear motors are also called linear motors, linear motors, linear actuators, and push rod motors.

[0003] The linear motor needs to be installed and fixed when it is used. The existing installation and fixing method is to directly install the linear motor in a fixed position. That is to say, the linear motor cannot be adjusted and corrected after installation. In the subsequent use, mechanical vibration and other reasons will cause the working end of the linear motor to be offset. The connection between the linear motor that cannot be corrected and adjusted and the working end will be subjected to a pulling force, which will cause the connection to become loose and shaken or even fail. Utility Model Content

During subsequent use, due to mechanical vibration and other reasons, the working end of the linear motor will be offset in position, and the connection between the linear motor that cannot be corrected and adjusted and the working end will be subjected to a pulling force, thereby causing the connection to become loose and shaken or even fail.
