Abstract
The utility model discloses a gear inner hole rolling and extruding clamp, comprising a tooth mould and a soleplate which is positioned under the tooth mould. At least three freely rolling steel balls whose sizes are same are arranged between the bottom surface of the tooth mould and the soleplate. The bottom edge position of the tooth mould extends out and is provided with a position limit ting, and one side of the tooth mould is provided with a cutter disengaging mechanism which comprises a bracket, a slide rod and a damping cylinder. The gear inner hole rolling and extruding clamp is used for processing the inner hole of the bevel gear of the differential mechanism of the automobile in a rolling and extruding mode. The gear inner hole rolling and extruding clamp can accomplish the micro fluctuation of the tooth mould. The gear inner hole rolling and extruding clamp ensures the coaxiality requirements of the clamp center and the main shaft center of a machine tool, further improves the processing quality of the inner hole, and prolongs the service life of the tool. Meanwhile, the cutter disengaging mechanism prevents a work piece being raised up, when the cutter is retracted. The damping cylinder drives the slide rod to accomplish fast feeding, stably feeding fast retracting operations. The gear inner hole rolling and extruding clamp satisfies the processing requirement, and improves the producing efficiency.
Description
Technical field
The utility model relates to a kind of anchor clamps that metalwork endoporus edging is pressed processing that are used for, and presses processing, can realize the special fixture of location automatically especially for automobile differential bevel gear endoporus edging.
Background technology
The automobile differential bevel gear is used for realizing differential motion when vehicle travels turning that its structural design and crudy are most important to traffic safety.There is endoporus at the center of differential bevel wheel, and an end is a sphere.Traditional method for machining bore is the Vehicle Processing made allowance, behind heat-treatment quenching, and grinding again.This processing method production efficiency is low, the cost height, and surface roughness and wear resistence all are difficult to reach requirement.Advanced processing method is to press processing with carrying out edging behind the endoporus finish turning, this just requires edging press tools such as cutter, anchor clamps that very high precision must be arranged, and existing endoporus edging pressure anchor clamps are a kind of rigid structure fully, be difficult to guarantee the axiality requirement at anchor clamps center and lathe center, this can make edging press tool discontinuity equalization on the one hand, damage too early, cause again on the other hand endoporus after the roll extrusion tapering, exceed standard with the axiality of tooth portion.Simultaneously, existing anchor clamps are when cutter lifts, and workpiece can not come off smoothly, and production efficiency also can not get improving.
The utility model content
The technical problems to be solved in the utility model is to overcome the weak point that automobile bevel gear endoporus edging is pressed existing anchor clamps in the processing, providing a kind of can locate automatically, improve the bore machining accuracy, prolong tool life, the Gear-driven positive pole grooving machine that can enhance productivity again, reduce cost simultaneously.
The technical solution of the utility model is: Gear-driven positive pole grooving machine, comprise tooth mould and the base plate that is positioned at tooth mould below, the useful gear ring of doing the workpiece location in tooth mould top, improvements are tooth mould bottom surfaces with base plate between at least three free roller steel balls that size is identical are arranged, there is spacing collar at overhanging place, base, tooth mould bottom, and is gapped between base and the spacing collar.
Further scheme is: between tooth mould bottom surface and the steel ball disk is arranged; Tooth mould endoporus has the axle of interference fits with it, and axle and base plate endoporus are gapped; Tooth mould one side has the cutter mechanism that takes off that anti-workpiece lifts; The described cutter mechanism that takes off is pneumatic telescoping mechanism, and it is flexible that rack-mount damping cylinder drives slide bar, pushes down the workpiece upper surface after slide bar stretches out.
Adopt above technical scheme,, make the tooth mould realize that in horizontal plane trace floats because the free rolling steel ball is arranged between tooth mould bottom surface and base plate, play automatic positioning action, guarantee anchor clamps center and the axiality requirement of lathe center, and then improve the endoporus crudy, prolong tool life.Disk in the anchor clamps and axle further improve the service precision and the reliability of anchor clamps.Tooth mould one side take off cutter mechanism, workpiece also is taken up in the time of can preventing that cutter from lifting.Damping cylinder in this mechanism can drive slide bar and realize that F.F., worker advance, the action of rewind down, satisfies processing request, enhances productivity.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
As figure, the disk 2 of tooth mould 7 and bottom thereof on base plate 4, has the spacing collar of overcoat 5 and outer shroud 6 formations by steel ball 3 floating supports around tooth mould base and steel ball, gapped between spacing collar and tooth mould base and the disk.Axle 1 becomes interference fits with the endoporus of tooth mould, disk, and becomes matched in clearance with lining on the base plate.The gear ring 8 at tooth mould top matches with the bevel gear part of workpiece 9.One side of tooth mould is provided with the cutter mechanism that takes off that anti-workpiece lifts, and is installed in damping cylinder 12 on the support 11 in this mechanism and drives slide bars 10 and realize that F.F.s, worker advance, the action of rewind down, after slide bar is overhanging, pushes down the upper surface of workpiece.
