Description
Technical field
The present invention relates to the intersecting aperture apparatus of automobile gearbox parts machining, specially a kind of toothholder brill cross hole folder
Tool.
Background technology
The fixture point two procedures adopted by existing toothholder processing cross hole are completed, and are completed initially with manual bench drill
Processing, manual positioning workpiece easily deflect, and after being drilled three hole of circumferencial direction, upper another fixture bores corresponding end-face hole, adopts
It is that heart axle is positioned, latch determines the mode of circumference steering, although simple structure, but cumbersome, and there is drill bit to break
The useless defect damaged is produced in workpiece, due to three hole machineds that part is even circumferential distribution, and is φ 5 on the face of cylinder deep
Hole machined, the useless loss rate of part are higher.
The content of the invention
The present invention is cumbersome, easy as unreasonable structure is present in order to solve existing toothholder processing cross hole fixture
Deflect and the higher problem of part cost loss rate, there is provided a kind of toothholder bores cross hole fixture.
The present invention adopts the following technical scheme that realization：Toothholder bores cross hole fixture, including can be to 90 degree of front side
Rotation and upper surface is provided with the support platform of through hole, is provided with sleeve-shaped rotary table, rotates work in the through hole of support platform
The upper end for making platform is provided with ring-type end cap, and rotary table upper end is socketed with the spindle body being secured to, sets on looped end lid
The alignment pin through spindle body is equipped with, support platform lower end is fixed with the cylinder body stretched in through hole, and cylinder body lower end is fixed with
Cylinder cap, is provided with upper end through the pull bar of spindle body, is provided with the piston in cylinder body on pull bar in cylinder body, and piston with
Pull bar is fixed by positioning sleeve, and the annular boss with its one is provided with the middle part of pull bar, and the upper and lower end face of annular boss is provided with
The lifting force ball bearing being enclosed within pull bar and lower thrust ball bearing, lifting force ball bearing upper end are provided with the bearing with through hole tensioner
Seat, the bearing gland that lower thrust ball bearing lower end is provided with through hole tensioner and is connected with bearing block, lifting force ball bearing and axle
Arranging between bearing and gap is left between limited location pad, and spacing pad and bearing block, pull bar upper end is cased with positioned at spindle body
The open washer of top, and locking nut is screwed with the pull bar of open washer upper end.
During operation, workpiece is placed on the looped end lid of rotary table by alignment pin, realize workpiece end face and
Circumferential registration, subsequently in the presence of hydraulic oil, piston driving pull bar is moved down on a small quantity, and open washer will work and compress, and realize work
Positioning；Then pass through that control rotary table is rotated and 90 degree of support platform is rotated, you can realize operative end surface and cylinder
Cross hole machined, overcomes existing toothholder processing cross hole fixture cumbersome as unreasonable structure is present, easy
Deflect and the higher problem of part cost loss rate.
Present configuration reliability reasonable in design, realizes automatic turning during workpiece cross hole machined, through once
The hole that clamping can be processed on both direction difference machined surface, solves the problems, such as repeated clamping workpiece, improves handling part
Convenient degree, reduce the triviality of operation, and Hydraulic Clamping Mechanism increase the clamping force of workpiece, it is ensured that during work pieces process
Will not be shifted by strong cutting force, improve hole site precision well, while working (machining) efficiency is improve, with structure letter
The advantage of single, easy to process and low cost.
