The utility model has a simple structure and is easy to operate. It is easy to fix workpieces of different shapes and sizes, and is worthy of promotion and application. However, the above device fixes the workpiece on the fixed table by pressing it. When the workpiece that needs to be drilled on the outer circle of the circular workpiece is fixed and processed, it may be displaced or loosened under the influence of cutting force or vibration, and it is impossible to drill holes on the outer circle of the circular workpiece. Multiple adjustments are required, which increases the difficulty and time cost of the operation. Therefore, in order to solve the above problems, a positioning tool for vertical drilling of the outer circle of a circular workpiece is proposed. Utility Model Content

[0004] The technical problem solved by the utility model is to provide a positioning tool for vertically drilling a hole on the outer circle of a circular workpiece, which has high practicability, can be easily operated and has a relatively simple structure.

[0005] To solve the above technical problems, a positioning tooling for vertical drilling on the outer circle of a circular workpiece provided by the utility model includes: a base fixed above the workbench, a fixed seat fixed on the side of the base, and a positioning disk fixed on the side of the fixed seat away from the base. A limiting block is fixed on the lower side of the positioning disk, a sliding block is slidably inserted on the limiting block, and the sliding block is fixed on both sides of the supporting block. An adjusting rod is arranged at the bottom of the supporting block, and the adjusting rod is threadedly connected to the fixed block. The fixed block and the supporting block are connected through the adjusting rod. A positioning pin is threadedly connected to the fixed seat, and a fixed pressing plate is installed on the positioning pin. A threaded column is fixed at the center position of the positioning disk, and a fixed nut is threadedly connected to the threaded column. A workpiece is inserted on the threaded column of the positioning disk, and the workpiece is fixed by the fixed pressing plate and the fixed nut.

[0006] As a further scheme of the utility model, the positioning disk is of a circular structure, and a threaded column is fixed at the center position on the side of the positioning disk away from the fixed seat.

[0007] As a further scheme of the utility model, the positioning pin is threadedly connected to the fixed seat, and the threaded column on the positioning pin and the positioning disk are at the same horizontal height position, so that the fixed pressing plate is horizontally fixed later.

[0008] As a further scheme of the utility model, the fixed pressing plate is of a U-shaped structure, and the opening side of the fixed pressing plate faces the positioning disk. The U-shaped structure reduces the shielding of the workpiece and facilitates observing the drilling situation of the workpiece.

[0009] As a further scheme of the utility model, the sliding block is of a T-shaped structure, and the two sliding blocks are respectively fixed on both sides of the supporting block oppositely.

[0010] As a further scheme of the utility model, there are two limiting blocks in total, which are fixed oppositely on both sides of the bottom of the positioning disk. T-shaped chutes matched with the sliding blocks are arranged on the limiting blocks. The sliding blocks on both sides of the supporting block move in the limiting blocks, so that the supporting block can be lifted and lowered stably.

[0011] As a further scheme of the utility model, an isosceles right triangle groove with a pointed angle facing downwards is arranged at the top of the supporting block.

[0012] As a further scheme of the utility model, the adjusting rod is evenly covered with threads. The adjusting rod passes through the bottom of the fixed block and is connected to the supporting block. The up and down movement of the supporting block can be adjusted by rotating the adjusting rod.

[0013] Compared with the related technology, a positioning tooling for vertical drilling on the outer circle of a circular workpiece provided by the utility model has the following beneficial effects:

[0014] 1. The utility model provides a positioning plate on the base, places the workpiece on the threaded column on the positioning plate, contacts and applies pressure to the workpiece through a fixed pressure plate and a fixed nut, and locks the position of the fixed pressure plate by tightening the positioning pin to ensure that the workpiece remains stable during the processing, so that the workpiece is not easily displaced when subjected to cutting force or vibration.

[0015] 2. The utility model provides a lifting support block under the positioning plate, and a triangular groove above the support block. The operator can quickly fix the position of the workpiece by placing the workpiece into the groove, which simplifies the fixing process and improves work efficiency. The groove design on the support block limits the horizontal movement of the workpiece, ensuring the stability of the workpiece during the drilling process, and at the same time disperses the pressure on the workpiece during processing to avoid displacement of the workpiece due to concentrated pressure.
