Abstract

[0002] A linear motor is a transmission device that converts electrical energy directly into linear motion mechanical energy without any intermediate conversion mechanism. It can be regarded as a rotating motor cut radially and unfolded into a plane.
[0003] In the existing linear drive motor technology, the connection block is usually fixed by traditional bolts. This method is not only cumbersome to install and disassemble, but also inefficient, especially when the electromagnet needs to be frequently replaced or repaired, which brings great inconvenience to the user. In addition, the traditional slider design often slides directly on the T-shaped magnetic guide rail. Due to the lack of effective shock-absorbing measures, the friction and vibration problems between the slider and the magnetic guide rail are prominent, which not only accelerates the wear of the slider and the magnetic guide rail and shortens the service life of the motor, but also the vibration may cause damage to the motor, affecting the smoothness and accuracy of the movement. For this reason, a linear traction motor is proposed. Utility Model Content

[0030] Working principle: First, the user slides the connecting block 8 into the interior of the T-shaped slide groove 15, and then rotates the threaded cap 18 by hand.
