In cooperation with the positioning mechanism, workpieces of different shapes and sizes can be positioned, facilitating laser marking and improving adaptability, so as to solve the problems that the mechanical structure design of the existing positioning platform is too complex, including too many components and transmission systems, resulting in difficult overall operation and maintenance, and the existing positioning platform is mainly designed for workpieces with regular shapes, and it is difficult to achieve effective positioning and fixation for workpieces with irregular shapes.

[0014] The beneficial effects of the present utility model:

[0015] 1. By setting up an extrusion mechanism, the effect of unilateral positioning is achieved, avoiding the problems of the traditional positioning mechanism being too complex and inconvenient for maintenance. In cooperation with the positioning mechanism, workpieces of different shapes and sizes can be positioned, facilitating laser marking and improving adaptability, so as to solve the problems that the mechanical structure design of the existing positioning platform is too complex, including too many components and transmission systems, resulting in difficulties in overall operation and maintenance, and the existing positioning platform is mainly designed for workpieces with regular shapes, and it is difficult to achieve effective positioning and fixation for workpieces with irregular shapes.

[0016] 2. By setting up an extrusion mechanism, when the piston is started, the piston pushes the push block to move vertically. The push block pushes the roller, and the roller is subjected to an external force, thereby driving the extrusion block to rotate on the connecting plate through the rotating rod to perform extrusion positioning on one side of the workpiece. While the simple structure is convenient for maintenance, unilateral positioning can also be achieved. When the piston is started, the motor is started at the same time. The motor drives the lead screw to rotate on the base, thereby driving the moving plate to slide on the chute, and then pushing the right-angle rotating plate to move. The right-angle rotating plate rotates on the moving plate and can be adjusted automatically according to the different shapes of the workpieces to improve positioning.

Cooperating with the positioning mechanism 4, workpieces of different shapes and sizes can be positioned, facilitating laser marking and improving the adaptability. To solve the problems that the mechanical structure design of the existing positioning platform is too complex, including too many components and transmission systems, resulting in difficult overall operation and maintenance, and the existing positioning platform is mainly designed for workpieces with regular shapes, and it is difficult to effectively position and fix workpieces with irregular shapes.

A rotating rod 35 is rotatably connected between the two connecting plates 34. The rotating rod 35 assists the pressing mechanism 3 to achieve the effect of unilateral positioning. The outer end of the rotating rod 35 is connected to a pressing block 36. The lower end of the pressing block 36 is rotatably connected to a roller 37. The roller 37 drives the pressing block, so that the pressing block 36 rotates on the connecting plate 34 through the rotating rod 35, thereby forming an inward extrusion on the workpiece to complete unilateral positioning. The roller 37 is movably connected to the push block 33. An auxiliary wheel 38 is rotatably connected to the right end of the pressing block 36. The pressing block 36 is movably connected to the workbench 2.

When starting the piston 32, start the motor 41 at the same time. The motor 41 drives the lead screw 42 to rotate on the base 1, thereby driving the moving plate 43 to slide on the sliding groove 44, thereby pushing the right-angle rotating plate 45 to move. The right-angle rotating plate 45 rotates on the moving plate 43 and can be adjusted automatically according to the different shapes of the workpiece. The baffle 47 limits the position of the right-angle rotating plate 45, thereby clamping and positioning the workpiece. After positioning, start the external laser marking machine to mark the workpiece.

Cooperating with the positioning mechanism 4, workpieces of different shapes and sizes can be positioned, facilitating laser marking and improving the adaptability, so as to solve the problems that the mechanical structure design of the existing positioning platform is too complex, including too many components and transmission systems, resulting in difficult overall operation and maintenance, and the existing positioning platform is mainly designed for workpieces with regular shapes, and it is difficult to effectively position and fix workpieces with irregular shapes.
