Description
Technical field
The present invention relates to end-tooth manufacturing technology fields more particularly to a kind of end-tooth intermediate flange to bore four hole hydraulic clips
Tool.
Background technique
As enterprise constantly develops, a large amount of NC postprocessing process equipments are applied and the specialized progress produced in enormous quantities, make
It obtains existing frock clamp to constantly bring forth new ideas and improve, abandons the work of previous highly energy-consuming, high consumptive material, high labor intensity and poor efficiency
Clamps, positive searching high quality, efficient production method, the new frock clamp to save human and material resources.
End-tooth intermediate flange part, process route are as follows: 1. vehicle big end surface, outer circle, interior nest, mesoporous, chamfering, 2. vehicle
Microcephaly's outer circle, end chamfer, smart car mesoporous, 3. draw internal spline, 4. bore four holes, 5. draw end-tooth.Wherein 4. process bores four holes and is
Processing is distributed four 2 bolts hole of φ on circle φ, it is desirable that four hole locations are relative to benchmark A internal spline, B end-tooth≤Φ 0.4.
When prior art end-tooth intermediate flange bores the work of four hole fixtures, it is with end-tooth intermediate flange major part outer circle Φ 3
Positioning datum, using internal spline as positioning datum when drawing end-tooth, four hole locations are surveyed relative to benchmark A internal spline, B end-tooth
Amount, and the positioning datum for boring four Kong Yula end-tooths is different, is reacted on processed end-tooth intermediate flange part, influences zero
Machining accuracy, the production efficiency of part, four hole location qualification rates of actual measurement are only 70%.Then design a kind of end-tooth intermediate flange brill
Four hole hydraulically operated fixtures, keep workpiece loading and unloading convenient, and accurate positioning improves the qualification rate and stability of end-tooth part, is market

Specific embodiment
As shown in the figure: a kind of end-tooth intermediate flange bores four hole hydraulically operated fixtures, including pedestal 1, positioning plate 2, hydraulic cylinder 3,
Support base 4, spring 5 press mechanism 6, bushing plate 7 and drill jig sleeve 8, and the pedestal 1 includes bottom plate 101 and is arranged in bottom plate 101
The vertical gripper shoe 102 of two sides, the opposite face of two vertical gripper shoes 102 open up card slot, the positioning along its short transverse
Plate 2 is fastened in card slot, and the pedestal of the hydraulic cylinder 3 is fixed on bottom plate 101, under the telescopic rod and positioning plate 2 of hydraulic cylinder 3
End face is affixed, and to drive positioning plate 2 to move up and down in the card slot, the support base 4 includes supporting lower seat 401 and support
The seat of honour 402 supports the lower end surface of lower seat 401 and the upper surface of positioning plate 2 affixed, and the upper surface of lower seat 401 is supported to pass through interior six
Angle fillister head screw 9 and the support seat of honour 402 are affixed, make that the seat of honour 402 is supported to move up and down along the hexagon socket cap head screw 9,
Displacement of the hexagon socket cap head screw 9 to limit the support seat of honour 402, the upper surface at the support seat of honour 402 open up dustpan shape
Groove 403, and the interior arc radius of the dustpan shape groove 403 is identical as 10 microcephaly's exradius of end-tooth intermediate flange, it is described
The both ends of spring 5 are respectively and fixedly connected among the lower end surface for supporting the upper surface of lower seat 401 and the support seat of honour 402, and by described
The stroke that mechanism 6 controls spring 5 is pressed, the mechanism 6 that presses includes supporting rib 601, connecting rod 602 and connector 603, described
Supporting rib 601 is in U-shape structure and to be fixed together to form rectangle frame with institute connecting rod 602, and is arranged around the support seat of honour 402,
Setting card in the support seat of honour 402 sets the strip groove 404 of supporting rib 601, the affixed connector 603 in the middle part of connecting rod 602, connector
603 is affixed by threaded post 604 and the lower seat 401 of support；The bushing plate 7 is mounted on two vertical supports by positioning pin 701
The top of plate 102, the spline mandrel that the intermediate setting direction of bushing plate 7 cooperates downward and with 10 internal spline of end-tooth intermediate flange
702, and the position of center line degree of 403 inner arc of spline mandrel 702, hydraulic cylinder 3 and dustpan shape groove is no more than 0.1mm, bushing plate 7
Through-hole is opened up, to be fixed together with 8 interference of drill jig sleeve.
The fixture course of work divides three phases to carry out, 1, be packed into end-tooth workpiece when, due to spring 5 head on support the seat of honour
402, make the height for supporting the spacing of the seat of honour 402 and spline mandrel 702 to be less than end-tooth, supporting rib 601 is pressed downward with hand, end
The small head end of face tooth intermediate flange 10 is placed on downward in the dustpan groove 403 at the bearing seat of honour 402, is then pushed home into end-tooth
Between flange 10, reach bushing plate 7 positioning spline 702 position of mandrel when, unclamp supporting rib 601, the end-tooth workpiece is in spring 5
Telescopic action under be pressed into the spline mandrel 702 of bushing plate 7 and positioned；2, when workpiece pressing, pass through 3 pressure of hydraulic cylinder
Effect, the telescopic rod stretching of hydraulic cylinder 3 make positioning plate 2 drive the lower seat 401 of bearing, the bearing seat of honour 402 pressure side surface from bottom to top
Tooth workpiece；3, when unloading end-tooth workpiece, by the effect of 3 pressure of hydraulic cylinder, the retraction of 3 telescopic rod of hydraulic cylinder makes 2 band of positioning plate
It is dynamic support lower seat 401, the bearing seat of honour 402 falls, the workpiece that simultaneous processing is completed be detached from the spline mandrel 702 of bushing plate 7 and with
It supports the seat of honour 402 to fall, supports the seat of honour 402 at this time by the telescopic action of spring 5, workpiece is made not completely disengage spline mandrel yet
702, then the spline mandrel 702 for needing manual depression supporting rib 601 that workpiece is made to completely disengage bushing plate 7 is pushed outwardly workpiece, takes
Lower workpiece, whole work process recycle progress like this.
Five freedom degrees of end-tooth workpiece are limited by the lower end surface of bushing plate 7 and spline mandrel 702, support the seat of honour 402
It holds out against end-tooth workpiece and limits its six-freedom degree, bushing plate 7 is fixed on pedestal 1, passes through hydraulic clamp and the support seat of honour
402 dustpan shape groove 403 loads and unloads end-tooth workpiece, and bushing plate 7 is not required to take off when clamping workpiece, and bores four holes and pull end face
Tooth two-step positioning datum is internal spline, improves the machining accuracy of 10 4 hole location of end-tooth intermediate flange.
And when needing to process the end-tooth of different size, i.e. 10 internal spline size of end-tooth intermediate flange is different, then
Only needing replacing bushing plate 7 can be realized, and scalability is strong.
The drawbacks of then novel clamp overcomes original fixture, under the premise of guaranteeing part production efficiency, structure is simple,
It is convenient to clamp, and work-handling is convenient, time saving and energy saving, improves machining accuracy, increases the enthusiasm for production of worker, improve life
Produce efficiency.
