Fixture device for laser processing of connecting rod cracking groove

Abstract

The invention relates to a laser machining clamp device of a connecting rod fracture splitting groove. The laser machining clamp device comprises a control unit, a clamp plate assembly, a front supporting plate, a rear supporting plate, a bearing platform, a first driving device, a push-pull plate, a front push-pull block and a rear push-pull block. The clamp plate assembly is used for fixing an automobile connecting rod. Both the front supporting plate and the rear supporting plate are fixed to the bearing platform, and the bearing platform is provided with two first through holes. The push-pull plate is located below the bearing platform. The bottom of the front push-pull block and the bottom of the rear push-pull block are fixed to the two ends of the push-pull plate correspondingly, and the front push-pull block and the rear push-pull block are movably embedded in the first through holes correspondingly. Both the front push-pull block and the rear push-pull block are provided with arc-shaped sliding grooves. The two ends of the clamp plate assembly penetrate through the front supporting plate and the rear supporting plate to be connected with the arc-shaped sliding grooves correspondingly. The first driving device is connected with the control unit and used for driving the push-pull plate to move up and down. By the adoption of the laser machining clamp device, flipping of the clamp plate assembly can be positioned accurately, the groove depth of the machined fracture splitting groove is even, and then, the quality of the machined fracture splitting groove is improved.

Description

technical field [0001] The invention relates to the technical field of laser processing of automobile connecting rod cracking grooves, in particular to a laser processing fixture device for connecting rod cracking grooves. 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. [0003] The traditional 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 fixture plate assembly for placing the automobile connecting rod can move in the X-axis direction to adjust the automobile ...

Problems solved by technology

However, in this patent, the fixture plate assembly is directly connected to the main shaft of the motor. After cutting the cracking groove of the first connecting rod, the motor rotates and directly drives the fixture plate assembly to rotate. Inertia will drive the fixture plate assembly to continue to rotate, which will easily lead to inaccurate positioning of the fixture plate assembly when it is turned over, which will lead to uneven groove depth of the processed cracking groove
