The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the technical program is described further.

With reference to figure 3, a kind of automobile platen processing tool comprises boring base plate 1, tension plug, drill bushing 9 and location backer 2; 1 has the hole on the described boring base plate, and the tension plug is through in this hole, and the swelling part of tension plug is exposed at boring base plate 1 upper surface, and the profile of swelling part is corresponding with processed first hole, 1.1 inner wall shape of neutralizing on the dish 2.1; Described drill bushing 9 and location backer 2 are located at boring base plate 1 upper surface, the position and processed neutralize the dish 2.1 be enclosed within on the swelling part after, correspondence is put at the seat, hole in second hole 1.2 on the platen 2.1, make processed neutralize the dish 2.1 be enclosed within on the swelling part after, prop up the hole seat in second hole 1.2 with the location backer, make the needs punching place aligned in position of drill bushing 9 and hole seat.

Described location backer 2 is the blocks that are fixed on boring base plate 1 upper surface, has screw on the block, is rotary with bolt in screw, the axial sensing of bolt is processed neutralize dish 2.1 circumferentially.

The quantity of described drill bushing 9 is consistent with processed second hole, 1.2 quantity of neutralizing on the dish 2.1.

Described drill bushing 9 is contained in boring base plate 1 upper surface by drill bushing bearing 7, and drill bushing bearing 7 and boring base plate 1 upper surface are fastening by interior hexagonal screw rod 11.

With reference to figure 4, described tension plug comprises positioning sleeve 3, elastic piston ring 4, elasticity inner cone ringfeder 6 and the tension mandrel outer axis of cone 5 of coaxial setting;

1 perforate of the shape of the described tension mandrel outer axis of cone 5 bottoms and boring base plate is corresponding; The tension mandrel outer axis of cone 5 middle parts are taper types, and described elasticity inner cone ringfeder 6 is enclosed within outside this taper type, and described elastic piston ring cover 4 is outside elasticity inner cone ringfeder 6, and described positioning sleeve 3 is enclosed within outside the elastic piston ring and with elastic piston ring 4 and cooperates; The bottom of the described tension mandrel outer axis of cone connects cylinder axis 10.
