Technical Field

The invention belongs to the technical field of actuating mechanisms of guide bar shogging and movement control systems of warp knitting machines, and particularly relates to a linear servo motor for a guide bar shogging and movement control system of a warp knitting machine and an assembling method of the linear servo motor.

Background

The traditional electronic guide bar shogging mechanism for the warp knitting machine adopts rotary servo as a driving element, and after a common rotary alternating-current servo motor rotates, the rotating action of the alternating-current servo motor is converted into the transverse movement of a guide bar through a certain device, so that the aim of driving the guide bar to shogging is finally fulfilled. The problems common to these systems are: because of adopting the rotary type alternating current servo motor as a driving element, the cost is reduced, but: on one hand, the production speed of the warp knitting machine is limited due to the lower starting frequency of the warp knitting machine; on the other hand, a certain mechanism is needed to convert the rotary motion into linear motion, so that the motion precision is reduced, and the transmission efficiency is also reduced.

To this end, patent specification CN100537872C discloses an actuator for an electronic bar shogging system of a warp knitting machine, specifically a bar shogging device of a flat type linear servo motor driven warp knitting machine. According to the technical scheme, a flat linear servo motor stator and a flat linear servo motor rotor which can move left and right relative to the flat linear servo motor stator are arranged on a frame of the warp knitting machine, and a support rod is connected to the left end of the flat linear servo motor rotor; the left side of the frame of the warp knitting machine is provided with a warp knitting machine guide bar capable of moving left and right, and the left end of the stay bar is connected with the guide bar.

However, the flat type linear servo motor driven warp knitting machine guide bar shogging device has the defects in use, and firstly, the device can only output shafts in one direction and cannot output shafts in two directions; secondly, the power can not be adjusted rapidly according to the requirement, the increase of the power needs to increase the longitudinal circumference, and the power-adjustable power device is not suitable for places with requirements on installation and use environment space.
