Detailed description of the invention
In conjunction with Fig. 1 to Fig. 3, the utility model is further described:
A kind of piston body locating and machining frock, including the clamping block 30 for clamping piston rod A outer wall arranged on base 10, clamping block 30 is stretched out at the two ends of piston rod A, base 10 is additionally provided with alignment pin 20 and constitutes grafting location fit for one end through hole with piston rod A, piston B is inserted by the piston rod A other end and a side end face of end face and clamping block 20 reclines, and the spacing between described alignment pin 20 and clamping block 30 is adjustable.
The alignment pin 20 arranged on base 10 and clamping block 30 is utilized to implement the Primary Location to piston rod A; using the external diameter of piston rod A as benchmark; preheated piston B is imported by the other end of piston rod A; interference fit between piston B and piston rod A; such that it is able to guarantee piston B and the piston rod A axiality coordinated and perpendicularity; utilize the spacing between alignment pin 20 and clamping block 30 adjustable; thus adjustable piston B is positioned at position suitable on piston rod A; and then guarantee the precision of next step machining piston body, improve the crudy of piston body.
Preferably, described base 10 being provided with bar hole 11, described alignment pin 20 is adjustable along bar hole 11 hole length direction, described clamping block 30 be positioned on the base 10 plate face at long bearing of trend place, bar hole 11 hole arrange.When needing the piston body of a kind of model of batch machining, piston sample bar is imported in clamping block 30, and the rod end through hole hole of piston sample bar is coordinated with alignment pin 20, then alignment pin 20 is fixed up, the batch location of the piston body to this model can be completed.
In the process of practical operation, the plate face vertical of described base plate 10, described clamping block 30 is positioned at the arranged above of alignment pin 20.Piston rod A is imported by the clamping block 30 of top, and utilize the alignment pin 20 being arranged below to coordinate with the through hole composition grafting of rod end under piston rod A, thus implementing the location to piston rod A, then the piston B of preheating is imported by the upper end of piston rod A, the side space of a whole page that piston B falls automatically with clamping block 30 reclines, complete to be automatically positioned, after cooling, take off piston body and process further.
Further, described clamping block 30 is provided with pressing plate 40, pressing plate 40 constitutes detachable connection with clamping block 30, is respectively provided with fluted and is formed for holding piston rod A through hole between clamping block 30 and pressing plate 40 binding face, and this through hole hole length direction is vertical and parallel with the length direction of bar hole 11；
