The trajectory auxiliary device of the laser cutting machine includes a machine body, a suspension bearing is arrangedat the middle of the inner wall of the upper end of the machine body and is sleeved with a shaft sleeve, an outer ring of the upper end of the shaft sleeve is provided with gear teeth, and a motor isarranged at the side, close to the suspension bearing, of the inner wall of the upper end of the machine body; a belt wheel is fixedly connected with an output shaft at the lower side of the motor, the belt wheel is movably connected with the shaft sleeve through a transmission belt, the suspension bearing is sleeved with a support cylinder which is arranged at the lower side of the shaft sleeve,a transmission block is fixed to the lower end of the suspension bearing, a guide rod penetrates through the transmission block, a step-shaped block is fixed to one end of the guide rod, the guide rod is sleeved with a spring between the step-shaped block and the transmission block, a mounting device penetrates through the step-shaped block, the upper end of the mounting device is connected withan emitter in a clamped mode, and a sliding block is fixedly connected to the lower end of the mounting device. The trajectory auxiliary device of the laser cutting machine is novel in structure, anda cutting trajectory control device of the laser cutting machine is provided through limit transmission.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a track auxiliary device for a laser cutting machine. Background technique [0002] Laser cutting occupies a large proportion in the field of precision processing. During processing, the processing trajectory data of the wire-cut parts is first input to the control system of the laser cutting machine, and the laser cutting machine performs cutting processing accordingly. During the processing, due to the influence of various factors , The laser transmitter often deviates, except for the obvious deviation, it is difficult for the operator to find out this situation, resulting in an increase in the reject rate. If there is a set of auxiliary devices, it is undoubtedly of great significance to limit the trajectory of the transmitter in real time and prevent it from deviating, which will undoubtedly improve the processing accuracy of laser-cut workpieces.
