Abstract

A linear drive mechanism comprises a shell and a fixed screw. A drive outer thread is disposed on the fixed screw. The shell is hollow. A rotary shaft penetrates the shell. A drive nut is fixed in the rotary shaft. A drive inner thread screwed with the drive outer thread is formed in the drive nut. A coil accommodating part is fixed on the rear side of the shell. A drive coil is disposed in the coil accommodating part. A magnetic element is fixed at a position, corresponding to the drive coil, on the rear side of the rotary shaft. The positioning component of the magnetic element is disposed on the rotary shaft. The linear drive mechanism is simple to operate, convenient to mount, high in drive precision, convenient to adjust, and capable of increasing drive precision and machining efficiency.

Description

technical field [0001] The invention relates to a linear drive mechanism. Background technique [0002] In the cutting process, it is necessary to drive the workpiece or the table to move forward and backward, and for the forward and backward movement, it is necessary to precisely control the distance of the forward and backward movement. Therefore, the precision requirements for the driving mechanism are very high. [0003] The existing linear drive mechanism often has the defects of complex structure, high cost, and difficult installation and positioning, which affects the machining accuracy, so it is necessary to improve it. [0004] For this reason, the designer of the present invention, in view of the above-mentioned defects, has researched and designed a linear drive mechanism to overcome the above-mentioned defects by concentrating on research and design, and integrating experience and achievements in related industries for many years.
