3D printing laser cutting machine head with anti-collision function

Abstract

The invention discloses a 3D printing laser cutting machine head with an anti-collision function. The 3D printing laser cutting machine head comprises an ejector bush. A motor is arranged at the rightend of the ejector bush. A rotary shaft is arranged on the outer wall of the left side of the motor. The inner wall of the rotary shaft is connected with the outer wall of the motor. An ejector coveris arranged on the outer wall of the rotary shaft. The inner wall of the ejector cover is connected with the outer wall of the rotary shaft in a lap joint mode. According to the laser cutting machinehead with the anti-collision function, through cooperation between the motor, a rotary rod, the rotary shaft and a machine head body, under the effect of a cutting torch, the motor is an alternatingcurrent servo motor, during variable frequency speed control, the phase voltage of a stator needs to be changed at the same time, the ejector bush and a connecting rod enable a supporting rod to be tightly fixed, accordingly, the shortcomings that an anti-collision bush of a traditional laser cutting machine head with an anti-collision function is connected to the laser cutting machine head body unfirmly, during using, the cutting torch and the anti-collision bush are prone to shaking, the machining precision is affected, the machining efficiency is reduced, and wasting is caused are overcome,the production and machining cost is saved for enterprises, and the machine head is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of processing machinery, in particular to a 3D printing laser cutting machine head with anti-collision function. Background technique [0002] With the rapid development of cutting technology, laser cutting machines are used more and more widely, including automobile manufacturing, home appliance manufacturing, aerospace and other fields. Laser cutting machines can realize the cutting of plates with arbitrary shapes in the plane. There is no protection on the cutting nozzle, and it is easy to damage the cutting nozzle when cutting the workpiece with frame structure, resulting in the inability to continue cutting and affecting production efficiency. In the prior art, for example, the invention patent with application number 201220405621.4 includes a laser cutting Machine head, a cutting nozzle is fixedly installed on the laser cutting machine head, and an anti-collision cover is set outside the cutting nozzle...

Problems solved by technology

[0002] With the rapid development of cutting technology, laser cutting machines are used more and more widely, including automobile manufacturing, home appliance manufacturing, aerospace and other fields. Laser cutting machines can realize the cutting of plates with arbitrary shapes in the plane. There is no protection on the cutting nozzle, and it is easy to damage the cutting nozzle when cutting the workpiece with frame structure, resulting in the inability to continue cutting and affecting production efficiency. In the prior art, for example, the invention patent with application number 201220405621.4 includes a laser cutting Machine head, a cutting nozzle is fixedly installed on the laser cutting machine head, and an anti-collision cover is set outside the cutting nozzle, and one end of the anti-collision cover is fixed on the laser cutting machine head, and the anti-collision cover is Cylindrical, although the invention has a simple structure, there are many deficiencies and defects. In the existing equipment, the design of the anti-collision sleeve has defects, and the connection between the anti-collision sleeve and the laser cutting machine head is not firm. During use, The cutting nozzle and the anti-collision sleeve are prone to tremors, which affect the processing accuracy, reduce the processing efficiency, and cause waste. In view of these situations, in order to avoid the above technical problems, it is necessary to provide a 3D printing laser cutting machine head with anti-collision function. Overcome the said drawbacks in the prior art
