[0005] Further, it further comprises a backing plate and a positioning nut, the backing plate is upwardly sleeved from the bottom end of the vertical shaft, and the positioning nut can be screwed from the bottom end of the vertical shaft; after the positioning nut is tightened, the positioning nut can press the backing plate upwardly on the bottom surface of the horizontal support bottom plate and make the rotating seat and the horizontal support seat tightly overlap.

[0006] Further, it further comprises a pressing block, the top edge of the rotating seat is installed with 2-4 pressing blocks through a pin shaft, each pressing block can rotate around the pin shaft, and the pressing block can press downwardly on the top surface outer edge of the disc plate class part blank to be trepanned.

[0007] Furthermore, the vertical mounting base is machined with a through hole, through which the drill bit of the drilling equipment can pass and perform drilling operations on the blank of the disc-type part.

[0008] During operation, after the hole at one end of the blank part of the disc plate to be drilled is machined, without disassembling the blank part, first remove the two locating pins, then loosen the locating nut, and rotate the rotating seat, which is placed flat on the top surface of the horizontal support base plate, 180° around the vertical shaft. Then, insert the locating pins again and tighten the locating nut again, thereby performing the drilling operation on the other end of the blank part of the disc plate. The two pairs of holes of the disc plate part machined in this way can always keep the same axis.

[0009] The beneficial effect of this utility model is that it can effectively improve work efficiency and product qualification rate. Attached Figure Description

Detailed Implementation

[0014] Figure 1 , Figure 2A novel hole-machining positioning device for the hole-making process of disc-shaped parts is shown. It is characterized by comprising a horizontal support base plate B, a vertical mounting seat A, a vertical shaft D, a rotating seat C, and positioning pins E. The lower end of the front side wall of the vertical mounting seat A is welded to two forward-extending support arms A1. The tops of the two support arms A1 are bolted to the horizontal support base plate B. A vertical shaft hole is milled in the center of the horizontal support base plate B. Two positioning pin holes B1 are also milled in the horizontal support base plate B, radially distributed on the left and right sides of the vertical shaft hole. The top surface of the rotating seat C... The part has a downwardly recessed material groove machined by a milling machine. The blank part F of the disc-shaped part to be drilled can be placed in the material groove. The center part of the material groove has a vertical shaft hole II machined by a milling machine. The rotary seat C also has two positioning pin holes II machined by a milling machine.
