Detailed ways

As shown in Figures 1 and 2, a positioning fixture for a double pipe joint according to the embodiment of the present invention includes a bottom plate 1 and a vertical plate 2. The bottom plate 1 and the vertical plate 2 are fixedly connected. The bottom plate 1 is fixed above the workbench. The vertical plate 2 is processed with a through hole 22 and a long slot 21 in the middle, and the through hole 22 is located above; the rotating positioning member 5 is installed at the through hole 22 and is equipped with a copper sleeve 4. The outer end of the rotating positioning member 5 is a positioning head 6. The cross-section of the positioning head 6 is an equilateral triangle, and the corners of the equilateral triangle are rounded; the upper guide and positioning member 7 is fixed on the middle of the upper surface of the vertical plate 2, and a guide hole 71 is processed through the middle of the upper guide and positioning member 7. A ceramic sleeve is installed in the hole 71, and the outer side of the upper guide positioning member 7 protrudes to form a positioning portion 72; the lower positioning rod 3 is fixed at the long slot 21, the middle part of the lower positioning rod 3 is a regular hexagonal prism, and the rotating rod 10 is screwed on the lower positioning rod 3 At the outer end of the rotating rod 10, the balance rod 11 is fixed on the lower part of the rotating rod 10; the set screw 8 is screwed on the upper part of the rotating rod 10. The end of the set screw 8 is also fixed with a handle 9. The center line of the set screw 8 is connected to the through hole. The centers of 22 are at the same height.

The precise positioning of the double-pipe joint is achieved through this positioning fixture. At the same time, the positioning fixture is fixed on the workbench. Through the up and down movement of the drilling equipment, the middle hole and the side hole can be processed on the double-pipe joint. Compared with manual drilling, In terms of holes, the positioning is precise and the operation is convenient.

During specific use, in order to facilitate understanding of the present invention, it will be described in conjunction with the accompanying drawings;

Processing the middle hole: As shown in Figure 8 and Figure 9, when processing the middle hole 123, first fit the double-tube joint to the outer wall of the vertical plate. At this time, the rotating positioning piece is embedded into the inner cavity of the double-tube joint. At the same time, The lower surface of the positioning part 72 is in contact with the positive positioning surface 125 of the double pipe joint, so the position of the double pipe joint is determined. Rotate the rotating rod to the vertical direction, and tighten the set screw 8. After that, the drill bit is moved from The upper part is guided through the guide hole 71 to process a middle hole 123 on the double pipe joint.

Processing of side holes: As shown in Figure 10, when processing side holes, first fit the double-tube joint to the outer wall of the vertical plate, so that the rotating positioning piece is embedded into the inner cavity of the double-tube joint.
