Description
Technical field
The utility model relates to automobile gearbox parts machining and intersects aperture apparatus, is specially a kind of toothholder and bores cross hole fixture.
Background technology
The fixture point two procedures that existing toothholder processing cross hole adopts completes, first manual bench drill is adopted to complete processing, manual positioning workpiece easily deflects, after having bored circumferencial direction three hole, another fixture upper bores corresponding end-face hole, what adopt is axle location, the mode that circumference turns to determined by latch, although structure is simple, but complex operation, and there is drill bit and break and produce useless defect of damaging within the workpiece, because part is three hole machined of even circumferential distribution, and be φ 5 deep hole machining on the face of cylinder, part loss rate of giving up is higher.
Summary of the invention
There is complex operation in order to solve existing toothholder processing cross hole fixture due to unreasonable structure, easily to deflect and the higher problem of part cost loss rate in the utility model, provides a kind of toothholder and bore cross hole fixture.
The utility model adopts following technical scheme to realize: toothholder bores cross hole fixture, comprise can to front side 90 degree to rotate and upper surface has the support platform of through hole, sleeve-shaped rotary table is provided with in the through hole of support platform, the upper end of rotary table is provided with ring-type end cap, rotary table upper end is socketed with the axle body fixing with it, looped end covers the alignment pin being provided through axle body, support platform lower end is fixed with the cylinder body stretched in through hole, and cylinder body lower end is fixed with cylinder cap, the pull bar of upper end through axle body is provided with in cylinder body, pull bar is provided with the piston being positioned at cylinder body, and piston and pull bar are fixed by positioning sleeve, the annular boss with its one is provided with in the middle part of pull bar, the upper and lower end face of annular boss is provided with and is enclosed within lifting force ball bearing on pull bar and lower thrust ball bearing, lifting force ball bearing upper end is provided with the bearing block with through hole tensioner, lower thrust ball bearing lower end is provided with through hole tensioner and the bearing gland be connected with bearing block, spacing pad is provided with between lifting force ball bearing and bearing block, and leave gap between spacing pad and bearing block, pull bar upper end cover has the open washer be positioned at above axle body, and the pull bar of open washer upper end is screwed with locking nut.
During operation, the looped end that workpiece is placed on rotary table by alignment pin covered, realize end face and the circumferential registration of workpiece, subsequently under the effect of hydraulic oil, piston driving pull bar moves down on a small quantity, and work compresses by open washer, realizes the location of work; Then rotate and support platform 90 degree rotation by controlling rotary table, can realize the cross hole machined of operative end surface and cylinder, overcoming existing toothholder processing cross hole fixture due to unreasonable structure exists complex operation, easily to deflect and the higher problem of part cost loss rate.
The utility model reasonable in design is reliable, achieve automatic turning during workpiece cross hole machined, the hole on the different machined surface of both direction can be processed through clamped one time, solve the problem of repeated clamping workpiece, improve the convenient degree of handling part, reduce the triviality of operation, and Hydraulic Clamping Mechanism increases the clamping force of workpiece, be subject to strong cutting force when ensureing work pieces process can not offset, improve hole site precision well, improve working (machining) efficiency simultaneously, there is simple, the easy to process and advantage that cost is low of structure.
