Abstract
The invention belongs to the technical field of welding and cutting equipment, in particular relates to a cutting torch lifting mechanism which comprises a lifting motor, a mounting frame, a nut, a lifting rod, a lead screw and eccentric clamping wheels. The lifting motor is mounted at the upper part of the mounting frame, an output shaft of the lifting motor is downwards connected with the lead screw which is provided with the matched nut, the lifting rod is sleeved outside the lead screw and fixed on the nut, and a cutting torch is mounted at the lower end of the lifting rod. The cutting torch lifting mechanism is characterized in that the symmetric eccentric clamping wheels are respectively arranged at both sides of the lifting rod, wheel grooves corresponding to the eccentric clamping wheels are dented on the outer wall of the lead screw, the edges of the wheel bodies of the eccentric clamping wheels are embedded in the wheel grooves, and the eccentric clamping wheels are used for stabilizing and clamping the lifting rod. The invention has simple and reliable structure, convenient mounting and maintenance and strong lifting stability by adopting the lifting structure of the lead screw and the nut. The eccentric clamping wheels and the wheel grooves are in a smart matched structure to stably and reliably clamp, thereby having strong suitability. The lifting motor adopting a direct current motor can bear great load and has high start speed.
