Abstract
The utility model discloses a cross axle processing clamping head, including collet bodies, collet bodies has a long circular hole chamber, and the upside pore wall installation clamping cylinder in long circular hole chamber promotes to press from both sides tight head and does radial action during the clamping cylinder action, the downside pore wall installation dividing head in long circular hole chamber, and it is just right from top to bottom to press from both sides tight head and dividing head, its characterized in that: the dividing head is done radial activity and is rotated with the graduation and set up, and dividing head fixed connection is at the last axle head of integral key shaft, and the downside pore wall in long circular hole chamber and the spline hole of worm wheel are passed in the lower axle head activity of integral key shaft, the worm wheel rotate locates collet bodies outer with adjust the worm -drive meshing, the lower axle head fixed connection adjusting screw of integral key shaft, the lower terminal surface rotation connection adjusting nut of worm wheel, the screw connects soon in succession between adjusting screw and the adjusting nut. The utility model discloses be exclusively used in the processing of cross axle, the processing of four jack -post faces of cross axle just can be accomplished to a clamping, simple structure, and the commonality is strong.
Description
[technical field]
This utility model 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, and having a vital part in differential mechanism is cross axle, cross axle be shaped as cross, adding and to process four jack-post faces man-hour, clamping is inconvenient, and working (machining) efficiency is low, because wanting multiple clamping, so machining accuracy can not be guaranteed very well.Therefore applicant develops a kind of cross axle processing special clamping head (patent No. 201220754574.4) in December in 2012 application on the 25th, 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 is relative complex, and can only be suitable for the cross axle processing of a kind of jack-post face diameter.
[summary of the invention]
The problem existed in view of currently known technology, the purpose of this utility model is intended to provide a kind of processing being exclusively used in cross axle, simple in construction, the cross axle processing and loading clamp head of highly versatile.
This utility model has adopted the following technical scheme that:
Cross axle processing and loading clamp head, including collet body, collet body has Long Circle vestibule, the upside hole wall of Long Circle vestibule installs clamping cylinder, clamping head is promoted to make radial action during clamping cylinder action, the downside hole wall of Long Circle vestibule installs dividing head, clamping head and dividing head are the most right, it is characterized in that: dividing head makees radially movable and indexing rotation setting, dividing head is fixedly connected on the upper axle head of splined shaft, the lower shaft end activity of splined shaft passes downside hole wall and the spline endoporus of worm gear of Long Circle vestibule, worm gear wheel is located at outside collet body and is engaged with regulation worm-drive, the lower shaft end of splined shaft is fixing connects 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 using technique scheme, this utility model simple in construction, highly versatile, its operation principle is: allow clamping head and dividing head clamp in cross axle workpiece is put into the Long Circle vestibule of collet body, then a cross axle jack-post face outwardly is carried out turnery processing or grinding, after a jack-post face machines, rotate regulation worm screw and drive worm gear, splined shaft and dividing head are made 90 degree of indexing and are rotated, then cross axle rotates 90 degree the most accordingly, the jack-post face turning to outside can be processed the most again, carry out according to this, workpiece clamped one time just can complete the processing in four jack-post faces；Further, adjusting screw rod, splined shaft and dividing head is made to move as radial position by rotation adjusting nut, so that it may to rapidly adapt to the cross axle of not coaxial cylindrical surface diameter, simple in construction, highly versatile.
[accompanying drawing explanation]
This utility model has a drawings described below:
Fig. 1 is structural representation of the present utility model.
[detailed description of the invention]
nullAs shown in the figure，Cross axle processing and loading clamp head of the present utility model，Including collet body 1，Collet body 1 has Long Circle vestibule 4，The upside hole wall of Long Circle vestibule 4 installs clamping cylinder 2，Clamping 3 is promoted to make radial action during clamping cylinder 2 action，The downside hole wall of Long Circle vestibule 4 installs dividing head 5，Clamping 3 and dividing head about 5 are the most right，The clamping end face of clamping 3 and dividing head 5 is designed to V-arrangement，Described dividing head 5 makees radially movable and indexing 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 passes downside hole wall and the spline endoporus of worm gear 7 of Long Circle vestibule 4，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 regulation worm screw 10 transmission，The lower shaft end of splined shaft 6 is fixing connects adjusting screw rod 9，The lower surface of worm gear 7 is rotationally connected adjusting nut 8，Joining clasp 11 is fixed in the lower surface of worm gear 7，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.
This utility model 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 that workpiece allows clamping head and dividing head clamp, then a cross axle jack-post face outwardly is carried out turnery processing or grinding, after a jack-post face machines, rotate regulation worm screw and drive worm gear, splined shaft and dividing head are made 90 degree of indexing and are rotated, then cross axle rotates 90 degree the most accordingly, the jack-post face turning to outside can be processed the most 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 as radial position by rotating adjusting nut, just can rapidly adapt to the cross axle of not coaxial cylindrical surface diameter.
