Description

Bent axle centering fixture

Technical field

The utility model belongs to mechanical field, is specifically related to a kind of bent axle centering fixture.

Background technology

The frock of existing bent axle centering is generally that a frock clamp body is installed on platen, on concrete the V-type seat mounting clamp of two trunnion location use, the pressure retaining mechanism of the compositions such as a plate, screw rod, nut, clamping screw that clamps bent axle is installed again, every kind of bent axle all needs a set of corresponding frock, be not suitable with flexible production, frock cost is high; This kind of bent axle centering frock, relatively simple for structure, operate fairly simple, but open the length direction location on grade centralized positioning and bent axle special plane owing to there is no the thrust of bent axle, the size of centre bore of bent axle and the centre bore distance to thrust Kai Dang center can not be controlled exactly, the requirement with regard to upper Digit Control Machine Tool processing after centering can not be realized.

Utility model content

Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of bent axle centering fixture is provided, and by simple adjusting, can realize the processing of multiple bent axle; By adopting the utility model frock, greatly reduce the cost of manufacture of frock; Owing to not needing to make new frock, concerning developing new product, the construction cycle will be shortened widely; Can meet subsequent handling centre bore is opened to the conforming requirement of grade centre distance to thrust.

The technical scheme that the utility model adopts is: a kind of bent axle centering fixture, comprise clamp body base plate, described clamp body plate upper surface is arranged with V-type seat, between two V-type seats, be provided with angle orientation seat, grade center positioning mechanism and depth of center hole positioner are driven in thrust, on described two V-type seats, be equipped with locating piece, angle orientation seat comprises positioning pedestal, described positioning pedestal is bolted on clamp body base plate, thrust is opened a grade center positioning mechanism and is comprised positioning seat and locating shaft, on positioning seat, have locating hole, on locating shaft, be socketed with spring, described locating shaft and positioning seat are slidably connected, depth of center hole positioner comprises axial location baffle plate, axial location seat and adjusting screw(rod), axial location baffle plate is arranged at clamp body plate upper surface, adjusting screw(rod) is through axial location seat, and be fixedly connected with axial location seat.

As preferably, between V-type seat and clamp body base plate, be bolted.

As preferably, also comprise adjustment screw and housing screw, described adjustment screw is connected with locating shaft, and described housing screw is connected with positioning seat.

The beneficial effects of the utility model are: two V-type seats are arranged on clamp body base plate, are convenient to place bent axle.The setting of angle orientation seat is convenient to determine the angle position of bent axle; The setting of grade center positioning mechanism is opened in thrust, is convenient to the center that definite crankshaft thrust is opened shelves; Depth of center hole detent mechanism is arranged on the rack sleeve of drilling machine, and the depth of center hole of being beaten to determine on bent axle is consistent, and centre bore is consistent to the distance at thrust Kai Dang center.
