Abstract
The invention discloses a cross axle processing clamp. The cross axle processing clamp comprises a clamp body (1), wherein the clamp body (1) is cylindrical; a screw hole (4) is formed in the upper surface of the clamp body (1); four V-shaped grooves (2) are symmetrically arranged on the clamp body (1) in the crossed direction; and a counterbore (3) is formed in the inner side of the clamp body (1). The processing clamp for cross axle turning solves the problem that the conventional cross axle rough lathing quality is difficult to control.
Description
Technical field
The present invention relates to a kind of auto parts manufacture field, especially is a kind of Universal joint pin machining fixture.
Background technology
Cross axle is a vital part in the truck drive shaft assembling universal coupling, and the flatness of perpendicularity, symmetry and each axis of cross axle four axle journals requires very high, and its processing tightness directly affects balance and the service life of universal coupling transmission.Present manufacturing procedure is normalizing, and tooth is drawn in turning, quenches, and cylindrical grinding for guaranteeing crudy, must be made specially
With the cross axle anchor clamps.The turning section is because the specific form of cross axle has anchor clamps clamping inconvenience now, and quality can not get effective control, so in the urgent need to a kind of special fixture, can guarantee the crudy of cross axle.
Summary of the invention
In order to overcome the existing rough turn crudy of cross axle problem rambunctious, the invention provides a kind of clamp for machining of cross axle turning.
The present invention has adopted following technical scheme to be: a kind of Universal joint pin machining fixture, it comprises clamp body, described clamp body is cylindric, upper surface at clamp body is provided with screw, on clamp body, be arranged with four V-shaped grooves along the cross direction, inboard at clamp body is provided with notch, is provided with counter sink in the bottom of notch.
The inboard of described clamp body evenly is provided with four notches, is provided with a notch between per two adjacent V-shaped grooves, and the bottom of each notch is provided with a counter sink; The upper surface of described clamp body evenly is provided with eight screws; The making material of described clamp body is the Crl2 steel.
The present invention has following beneficial effect: clamp body of the present invention adopts material C rl2, can guarantee precision and the service life of anchor clamps, anchor clamps adopt the axle location of cross axle, cut 4 V-shaped grooves by line on the anchor clamps, 4 V-shaped grooves are uniform on anchor clamps, four axles as the fixed cross axle, feel relieved with axle like this, selected surplus to show and the thick benchmark of conduct uniformly, just can guarantee also that axle off-centre can not occur in the rear T of adding, thereby guarantee the flatness of perpendicularity, symmetry and each axis of cross axle four axle journals.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is top view of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, the invention provides a kind of Universal joint pin machining fixture, it comprises clamp body 1, the making material of clamp body 1 is the Crl2 steel, clamp body 1 is cylindric, evenly is provided with eight screws 4 at the upper surface of clamp body 1, is arranged with four V-shaped grooves 2 along the cross direction on clamp body 1, evenly be provided with four notches 3 in the inboard of clamp body 1, be provided with a counter sink 3 between per two adjacent V-shaped grooves 2.
When the present invention uses, remove first the chuck on the engine lathe main shaft, then these anchor clamps are loaded onto, by location, hole and connecting bolt anchor clamps are installed to engine lathe main shaft L, then four axles with cross axle are put into respectively in the V-shaped groove 2, compress.Then by pressing plate, bolt is fixed on cross axle in the V-shaped groove 2, so just can process end face and hole.These anchor clamps have solved a difficult point of cross axle turning processing, have guaranteed the machining accuracy of four axial end and centre bore benchmark in following process, have guaranteed the symmetry size of four axle journal end faces to the spider center.
