Abstract
The invention discloses a cross shaft machining chuck comprising a chuck body, wherein the chuck body is provided with a slotted hole cavity; the hole wall at the upper side of the slotted hole cavity is provided with a clamping oil cylinder; the clamping oil cylinder drives a clamping head to radially act when acting; and the hole wall at the lower side of the slotted hole cavity is provide d with an indexing head vertically aligning to the clamping head. The cross shaft machining chuck is characterized in that the indexing head is arranged to radially move and do indexing rotation; the indexing head is fixedly connected to the upper shaft end of a spline shaft; the lower shaft end of the spline shaft movably penetrates through the hole wall at the lower side of the slotted hole cavity and an inner hole of a spline of a worm gear; the worm gear is rotationally arranged outside the chuck body and is meshed with a regulating worm in a driving way; the lower shaft end of the spline shaft is fixedly connected with a regulating screw rod; the lower end surface of the worm gear is rotationally connected with a regulating nut; and the regulating screw rod is in threaded rotational connection with the regulating nut. The cross shaft machining chuck is specially used for machining a cross shaft and is simple in structure and high in universality; and four shaft cylinders of the cross shaft can be machined through one-time clamping.
Description
[technical field]
The present invention relates to a kind of special clamping head for the processing of automobile differential cross axle.
[background technology]
Differential mechanism is the vitals of car transmissions, has a vital part to be cross axle in differential mechanism, and the shape of cross axle is cross, add and will process four jack-post faces man-hour, clamping is inconvenient, and working (machining) efficiency is low, because want multiple clamping, so machining accuracy can not be guaranteed very well.Therefore applicant develops a kind of cross axle in application on December 25th, 2012 and processes special clamping head (patent No. 201220754574.4), workpiece clamped one time just can complete the processing in four jack-post faces, not only improve working (machining) efficiency, and improve machining accuracy.But above-mentioned cross axle processing special clamping header structure relative complex, and the cross axle processing of a kind of jack-post face diameter can only be suitable for.
[summary of the invention]
In view of current known technology Problems existing, object of the present invention is intended to provide a kind of processing being exclusively used in cross axle, and structure is simple, the cross axle processing and loading clamp head of highly versatile.
The present invention takes following technical scheme:
Cross axle processing and loading clamp head, comprise collet body, collet body has Long Circle vestibule, the upside hole wall mounting clamp locking oil cylinder of Long Circle vestibule, promote clamping head during clamping cylinder action and make radial action, the downside hole wall of Long Circle vestibule installs dividing head, clamping head and dividing head are just right up and down, it is characterized in that: dividing head does radial movable and calibration rotation setting, dividing head is fixedly connected on the upper axle head of splined shaft, the lower shaft end activity of splined shaft is through the downside hole wall of Long Circle vestibule and the spline endoporus of worm gear, worm gear wheel is located at outside collet body and is engaged with adjustment worm-drive, the lower shaft end of splined shaft is fixedly connected with adjusting screw(rod), the lower surface of worm gear is rotationally connected adjusting nut, between adjusting screw(rod) with adjusting nut, screw thread spins and is connected.
After adopting technique scheme, structure of the present invention is simple, highly versatile, its operation principle is: allow clamping head and dividing head clamp in Long Circle vestibule cross axle workpiece being put into collet body, then turnery processing or grinding are carried out to a cross axle jack-post face outwardly, after a jack-post face machines, rotate and regulate worm screw to drive worm gear, splined shaft and dividing head are made 90 degree of calibration and are rotated, so cross axle is corresponding rotation 90 degree also, now can process turning to the jack-post face in outside again, carry out according to this, workpiece clamped one time just can complete the processing in four jack-post faces, further, by rotating adjusting nut, adjusting screw(rod), splined shaft and dividing head are moved do radial position, just can adapt to the cross axle of disalignment cylinder diameter fast, structure is simple, highly versatile.
[accompanying drawing explanation]
The present invention has following accompanying drawing:
Fig. 1 is structural representation of the present invention.
[detailed description of the invention]
As shown in the figure, cross axle processing and loading clamp head of the present invention, comprise collet body 1, collet body 1 has Long Circle vestibule 4, the upside hole wall mounting clamp locking oil cylinder 2 of Long Circle vestibule 4, promote clamping head 3 during clamping cylinder 2 action and make radial action, the downside hole wall of Long Circle vestibule 4 installs dividing head 5, clamping head 3 and dividing head about 5 just right, the clamping end face of clamping head 3 and dividing head 5 all designs forming V-shape, described dividing head 5 does radial movable and calibration rotation setting, dividing head 5 is fixedly connected on the upper axle head of splined shaft 6, the lower shaft end activity of splined shaft 6 is through the downside hole wall of Long Circle vestibule 4 and the spline endoporus of worm gear 7, splined shaft 6 is slidably matched with the spline endoporus of worm gear 7, worm gear 7 rotates to be located at outside collet body 1 and engages with the transmission of adjustment worm screw 10, the lower shaft end of splined shaft 6 is fixedly connected with adjusting screw(rod) 9, the lower surface of worm gear 7 is rotationally connected adjusting nut 8, the lower surface of worm gear 7 is fixedly connected with snap ring 11, the upper surface of adjusting nut 8 is provided with step 12, step 12 active card is connected in snap ring 11, between adjusting screw(rod) 9 with adjusting nut 8, screw thread spins and is connected.
The present invention is performed such cross axle processing: put into by cross axle workpiece in the Long Circle vestibule of collet body, clamping cylinder action promotes clamping head radial action and is clamped by clamping head and dividing head by workpiece, then turnery processing or grinding are carried out to a cross axle jack-post face outwardly, after a jack-post face machines, rotate and regulate worm screw to drive worm gear, splined shaft and dividing head are made 90 degree of calibration and are rotated, so cross axle is corresponding rotation 90 degree also, now can process turning to the jack-post face in outside again, carry out according to this, workpiece clamped one time just can complete the processing in four jack-post faces, when processing different size cross axle, adjusting screw(rod), splined shaft and dividing head can be made to move do radial position by rotating adjusting nut, just can adapt to the cross axle of disalignment cylinder diameter fast.
