In the bar traverse actuator, whether the bar traverse drive device and the bar installation are on the same plane will determine the displacement error of the bar traverse.
Once not in the same plane, the amount of displacement generated by the drive is transmitted to the bar through the ram, and the transmission of the displacement will produce an error that affects the accuracy of the traverse. Therefore, when the bar is swung to the center of the entire swing, the driving device, the jack, and the bar are required to be on the same plane, so that the traverse shift caused by the swing of the bar is minimized, thereby maximizing Limit the displacement accuracy of the bar.
Different actuators with different traversing mechanisms have their own advantages and disadvantages. Different actuators should be selected according to the actual production needs of different products.
The warp knitting machine has extremely short needle front and needle back traverse time. Therefore, the numerical control warp knitting machine requires the electronic traverse system to drive the comb to complete the "stop-move-stop" traverse movement in a very short time. The electronic traverse motion performance of the bar is the main factor affecting the speed of the warp knitting machine.
For example, the high-speed absolute encoder is used in the spindle signal device. The machining precision of the mechanical components of the traverse movement is high and the cooperation between the components and the components must be tight. The traverse drive device and the comb Should try to use the longer comb ejector rod on the same plane, which is beneficial to improve the traverse accuracy of the comb. When the CNC warp knitting machine is running, the machine should be prevented from resonating, so as not to affect the working stability of the electronic traverse system.
