Transmission mechanism of laser cutting machine

Abstract

The invention discloses a transmission mechanism of a laser cutting machine, comprising a rack, two sliding seats, a positioning plate, a transmission shaft, a driving device and two groups of synchronous wheel components, wherein the positioning plate is connected with the two sliding seats; the two ends of the transmission shaft are arranged on the sliding seats; the driving device is connected with the transmission shaft and is fixed on the positioning plate; a laser cutting head is connected with the positioning plate; the rack comprises two guide rails and two transmission belts which are respectively connected with the two ends of each guide rail; the sliding seats are arranged on the corresponding guide rails in a sliding manner; the synchronous wheel components are arranged on the corresponding sliding seats; each sliding seat comprises a first supporting plate and a second supporting plate; each synchronous wheel component comprises a first synchronous wheel, a second synchronous wheel, a large wheel and a synchronous belt; the first synchronous wheels are fixedly connected with one end of the transmission shaft; the large wheels and the first synchronous wheels are mutually connected by the synchronous belts; the second synchronous wheels and the large wheels are arranged on the same wheel shaft; the transmission belts penetrate through the sliding seats and are meshed with the second synchronous wheels; in working, the driving device drives the driving device, the transmission shaft and the sliding seats to slide along the guide rails so as to enable the laser cutting head to move to a specific position.

Description

technical field [0001] The invention relates to a transmission mechanism, in particular to a transmission mechanism of a laser cutting machine. Background technique [0002] Existing laser cutting machines usually include a machine base, a drive shaft for fixing the laser cutting device, and a transmission device that pushes the beam to move on the machine base. The machine base is provided with a left guide rail and a right guide rail. The transmission device includes a first transmission system and a second transmission system; the first transmission system includes a left motor and a left screw, the second transmission system includes a right motor and a right screw, and the two ends of the beam are connected to the left screw and the right screw. The screw rod cooperates with the transmission and moves along the left and right guide rails. [0003] However, the transmission device of the above-mentioned laser cutting device adopts the cooperation of the left and right m...

AI Technical Summary

Problems solved by technology

[0003] However, the transmission device of the above-mentioned laser cutting device adopts the cooperation of the left and right motors to drive the movement of the beam, which is prone to problems such as poor coordination between the first transmission system and the second transmission system, and poor consistency of left and right cutting. After long-term operation, the beam is prone to swing , making it difficult to guarantee the machining accuracy

Moreover, the transmission device with a screw rod is bulky, heavy, and complex in structure, which makes it difficult to process and assemble related parts, and the overall cost is high
