Abstract

The invention discloses a linear electric cylinder capable of accurate zeroing. The method is characterized in that the method is characterized in that the cylinder comprises a motor bracket; a motoris arranged at the side edge of the motor bracket; an end part of the motor support is connected with a second bracket; an end part of the second bracket is connected with a first bracket; a first screw rod support is fixed at the end part of the first bracket; the first screw rod support is detachably connected with the first bracket; a hollow groove is formed in the first lead screw support, anda lead screw is arranged in the hollow groove in a matched mode; a working platform is movably connected to an opening of the hollow groove; a second lead screw support is arranged at the end of thefirst lead screw support, and the second lead screw support is connected with one end of the lead screw in a matched mode. Through the positioning mechanism, the problem of zero point positioning of the linear electric cylinder and the problem of insufficient positioning precision caused by installation are effectively solved.

Description

technical field [0001] The invention relates to the technical field of precision manufacturing, in particular to a linear electric cylinder that can be precisely reset to zero. Background technique [0002] Most of the current linear electric cylinders (hereinafter referred to as linear cylinders) use relative encoders. When using relative encoders, there is a problem of setting the starting zero point. Generally, the linear cylinder platform is moved to the linear cylinder by controlling the motor. After both ends, when the platform is blocked, the zero point of the linear cylinder is set by judging the control current of the motor. However, it often occurs that the platform has not reached the actual physical zero point due to installation or load problems; although the zero point positioning accuracy is improved by adjusting the size of the blocking current, the mechanical part is in the process of movement due to changes in motor performance parameters. , The deformatio...
