Device and method for one-way vertical laser cutting cracking groove of automobile connecting rod

Abstract

The invention relates to a device and method for unidirectional vertical laser cutting of automobile connecting rod fracture splitting notches. The device comprises a control unit, a laser cutting head, a laser, a workbench, an X-axis moving platform, a Y-axis moving platform, a Z-axis moving platform, a fixture plate, a fixture body and drive devices for correspondingly driving the X-axis moving platform, the Y-axis moving platform and the Z-axis moving platform to move. The laser and the drive devices are all connected with the control unit. The laser cutting head is connected with the laser. The laser is connected with the Z-axis moving platform. The Z-axis moving platform is connected with the Y-axis moving platform. The fixture plate is rotationally connected with the fixture body. The fixture body is fixed to the X-axis moving platform. Both the X-axis moving platform and the Y-axis moving platform are mounted on the workbench. According to the device and method, after the first connecting rod fracture splitting notch is cut through the laser cutting head, the fixture plate rotates around the fixture body by 180 degrees, then the second connecting rod fracture splitting notch is cut through the laser cutting head, the complexity of the machining procedures of the fracture splitting notches is simplified, and the machining accuracy of the fracture splitting notches is improved.

Description

technical field [0001] The invention relates to the technical field of laser processing, and more particularly relates to a device and method for unidirectional vertical laser cutting cracking grooves of automobile connecting rods. Background technique [0002] The technology of using laser to process cracking grooves of automobile connecting rods is being further improved. Laser processing cracking grooves has the advantages of narrow slit, fast speed, no tool wear, and can greatly improve cracking quality. It is the first choice for initial cracking groove processing in connecting rod cracking technology. development trend. The existing domestic method of laser processing the cracking groove of the automobile connecting rod is generally to adopt the laser cutting head to move in the Y-axis and Z-axis directions of the three coordinate axes, and the clamp body for placing the connecting rod can move in the X-axis direction to adjust the position of the connecting rod ; Whe...

The existing domestic method of laser processing the cracking groove of the automobile connecting rod is generally to adopt the laser cutting head to move in the Y-axis and Z-axis directions of the three coordinate axes, and the clamp body for placing the connecting rod can move in the X-axis direction to adjust the position of the connecting rod ; When processing the cracking groove, after cutting the right cracking groove, it is necessary to translate the laser cutting head along the Y axis and rotate the laser cutting head 180 degrees to cut the left cracking groove. It is easy to cause deviations in the depth of the cracking grooves on both sides. In addition, since the laser cutting head needs to be translated and then rotated, this will also increase the complexity of the process of processing the cracking grooves; these will affect the quality and efficiency of the products produced by the enterprise
