Detailed description of the invention
Below the present invention is described in further details.
As shown in Fig. 1,2,3,4,5, a kind of Wedge-type Combined machining of the present invention device, comprising:
Base 1, in the middle part of base, upper surface is inclined-plane, its inclination angle is α, in the middle part of base, upper surface center is provided with screw, base 1 two ends are provided with the through hole of above-below direction, alignment pin 2 is inserted with in through hole, through hole and alignment pin 2 are interference fit, base 1 one side mounting block plate 8, part 5 to be processed is placed on base 1, the unthreaded hole at part 5 two ends to be processed is inserted in alignment pin 2, screw thread is arranged at alignment pin 2 top, with nut 3, alignment pin 2 and part 5 to be processed are tightened up, packing ring 4 is provided with between nut 3 and part to be processed 5, movable wedge 6 is inserted with between upper surface and part to be processed 5 in the middle part of base 1, movable wedge 6 lower surface is inclined-plane, its angle of inclination beta is equal with upper surface inclination angle of inclined plane α in the middle part of base 1, direction is contrary, movable wedge 6 is placed in the middle part of base 1 and can slides up and down along inclined-plane behind upper surface inclined-plane, movable wedge 6 upper surface remains parallel with base 1 lower surface, be connected by adjusting bolt 9 between movable wedge 6 with baffle plate 8, movable wedge central authorities have kidney slot, lock-screw 7 is screwed onto on the screw at base 1 center through kidney slot.
