Specific embodiment
Utility model is described in detail with reference to the accompanying drawings and examples.
As shown in Fig. 1 to 7, the utility model proposes concealed alignment pin, including positioning pin bearing 1, be vertically inserted into
Position the alignment pin 3 inside pin bearing 1, vertical the first auxiliary pin 5 being inserted into inside positioning pin bearing 1 and be transversely mounted and put
Enter the second auxiliary pin 7 inside the positioning pin bearing 1, the seat body for positioning pin bearing 1 is provided with for installing alignment pin 3
Alignment pin mounting hole 101 and for install first aid in pin 5 vertical auxiliary pin-and-hole 102, position pin bearing 1 inside also have
There is a horizontal auxiliary pin-and-hole 103 extended transversely through in the alignment pin mounting hole 101 and vertical auxiliary pin-and-hole 102, it is laterally auxiliary
The inner side of a fixed spring stop nut 9 at the aperture of pin-and-hole 103, spring stop nut 9 is helped to be provided with the first fixed pressure
Contracting spring 8, the second auxiliary pin 7 is inserted in laterally auxiliary pin-and-hole and held out against in the first compression spring 8, before the second auxiliary pin 7
End is square cutting 701, and the joining place of the cutting 701 and second auxiliary pin rearward end is to incline sliding shoulder 702, and first is auxiliary
Help the shaft of pin 5 to be provided with the square groove 501 for coordinating cutting 701 to run through, and there is laminating top upward at the notch of square groove 501
Tight to slide shoulder 502 in the transition for inclining sliding shoulder 702, the bottom of the first auxiliary pin 5 is additionally provided with the second compression spring 6, cutting 701
Through square groove 501 and can be plugged into that the alignment pin is held out against into lock-bit in alignment pin mounting hole, the bottom of the alignment pin sets
There is the 3rd compression spring 4.
Fixed one of the hole wall side holding screw 2 for being used for the slide-and-guide of alignment pin 1 of alignment pin mounting hole 101, it is fixed
The shaft of position pin 1 is provided with the guide chute 301 that the head of matching holding screw 2 is inserted.The shaft of alignment pin 1 is provided with cooperation
Spacing alignment pin outer groove 302 is inserted in cutting 701.Vertical width of the vertical depth of square groove 501 more than cutting 701.
Fig. 7 is referred to, when specifically used, will first need the part of processing to be had good positioning using part positioning and clamping, after positioning,
First auxiliary is sold pressure by part noumenon part, and when the first auxiliary pin pressure, transition cunning shoulder 502 is descending, now to inclining
Sliding shoulder 702 is not fettered, and the depth of the relative rising of the enough cuttings 701 of the depth of square groove 501, so in the first compression
In the presence of spring, the second auxiliary pin is directly deep into alignment pin mounting hole, and the side wall of alignment pin is withstood in the front end of cutting.
After processing except positioning hole, it is possible to use the mechanism of numerical control programming control lathe allows enforcement division directly by positioning
