[0002] Disc-type workpieces are relatively common in the field of mechanical processing. Some disc-type workpieces need to be drilled on the outer cylindrical surface. The traditional method is to manually mark the drilling position, then clamp the workpiece with flat-nose pliers or special fixtures, and then use a vertical drilling machine to drill holes according to the marks, and then clamp and rotate the disc-type workpiece again to drill the next hole.

[0003] According to the Chinese patent application number: CN202221354964.2, a simple and fast tooling for punching holes on the outer circle of a disc-like workpiece is disclosed. The positioning shaft is horizontally extended and fixed on the side wall of the base. The positioning shaft can slide with the center hole of the disc-like workpiece. The pressing plate is a long strip plate with an "L"-shaped structure and a waist groove is provided on the long side. The pressing plate can slide through the waist groove to penetrate the outer side of the disc-like workpiece of the positioning shaft. The short side of the "L"-shaped structure of the pressing plate faces the disc-like workpiece and can be pressed against the outer circle of the disc-like workpiece. The set screw is engaged with the threaded section on the outer side of the positioning shaft and can be pressed against the outer end face of the long side of the pressing plate. The utility model makes the outer circle axis of the disc-like workpiece form a horizontal state through the positioning shaft, and then the "L"-shaped pressing plate cooperates with the set screw to axially press and radially hook the disc-like workpiece, thereby improving the rigidity of the disc-like workpiece and realizing stable and reliable positioning, so that it is conducive to improving the punching efficiency and punching quality, and has the characteristics of simple structure, stable and reliable clamping, and good rigidity.

[0004] At present, a punching tool that can achieve rapid positioning still has some shortcomings. For example, after the metal disc is positioned, when punching holes in other positions later, it is necessary to manually loosen the set screws and adjust the position of the metal disc, which reduces the punching efficiency of the metal disc.
