Abstract
A precision positioning fixture for precision processing of fine forged differential half axle gears comprises an expander, a spline expansion sleeve, a sleeve body, an elastic gasket, a floating disc, a transitional disc body, a floating disc retaining mechanism and a plurality of steel balls, wherein the spline expansion sleeve mounted on the expander is used for mounting a half axle gear, the sleeve body is arranged on the inner end surface of the spline expansion sleeve, the elastic gasket clinging to the end surface of the sleeve body is mounted on the expander, the floating disc is pressed on the end surface of the sleeve body, the transitional disc body contacts with a spherical surface of the floating disc and clings to the elastic gasket, the floating disc retaining mechanism is used for fixing the floating disc onto the transitional disc body, and the steel balls are disposed between the floating disc and the half axle gear required to be precisely processed. The precision positioning fixture has compact structure, flexible operation, accurate positioning, reliable clamping, easily detached workpieces, high production efficiency, low labor intensity, high processing precision, uniform meshing backlashes and long service life, and can be widely applied to precision processing of fine forged differential half axle gears.
Description
Affiliated technical field the present invention relates to a kind of finish forge differential side gear fine finishining precision location clamp, can be widely used in the fine finishining of finish forge differential side gear.
The fine finishining of the existing finish forge differential side gear of background technology, because no reliable positioning fixture, axle shaft gear is difficult to satisfy dimensional tolerance and Geometrical Tolerance Principle, is installed in back weak point in service life on the differential mechanism.
Summary of the invention the object of the present invention is to provide a kind of compact conformation, flexible operation, accurate positioning, reliable clamping, work-handling is easy, productivity ratio is high, labour intensity is low, machining accuracy is high, guarantee that meshing backlass is even, the finish forge differential side gear fine finishining precision location clamp of long service life.
In order to achieve the above object, finish forge differential side gear fine finishining precision location clamp of the present invention, comprise expander, be installed in the spline ringfeder that is used to install axle shaft gear on the expander, be installed in the body on the spline ringfeder inner face, be installed in elastic washer on the expander near the body end face, be pressed against the floating disc on the body end face, the transition disk body that contacts with the floating disc sphere and install near elastic washer, floating disc is fastened to floating disc maintaining body on the transition disk body, is installed in several steel balls between the floating disc and the fine finishining axle shaft gear gear teeth.
Finish forge differential side gear fine finishining precision location clamp of the present invention, said steel ball is 3.
Finish forge differential side gear fine finishining precision location clamp of the present invention because of differential side gear and spline have position degree requirement, will guarantee the installation requirement of bevel gear simultaneously, therefore, and must be with spline and profile of tooth location grinding.
Finish forge differential side gear fine finishining precision location clamp of the present invention, its operation principle is: because the spline and the flank of tooth act on simultaneously, must cause the location, can't guarantee in order to eliminate the product quality that causes the location, transition disc in the transition disk body and floating disc are made spherical shape, contact with profile of tooth with three steel balls and locate and locate with the spline ringfeder.Expander is in the tension process, spline ringfeder spreading, contact with gear spline, gear is located with spline, in clamping process, might cause one of them or two profiles of tooth not to contact with steel ball, by the swing of floating disc and transition disc, and elastic washer, in clamping process, move by expander backward, guarantee spline ringfeder and workpiece tensioner, continue to move after the tensioner steel ball contact with profile of tooth, owing to floating disc around spherical floating, to the last three steel balls contact with the gear equilibrium, make profile of tooth location, thereby solved the problem that spline and profile of tooth are crossed the location.
Finish forge differential side gear fine finishining precision location clamp of the present invention, compact conformation, flexible operation, accurate positioning, reliable clamping, work-handling is easy.
Finish forge differential side gear fine finishining precision location clamp of the present invention, the error that cause the location when eliminating differential side gear fine finishining, solve the Working position precision of the axle shaft gear internal spline and the outside diameter of gear, bearing-surface, guarantee that simultaneously meshing backlass is even, the machining accuracy height, the workpiece long service life.
Finish forge differential side gear fine finishining precision location clamp of the present invention, easy to operate, be easy to the loading and unloading of workpiece, to increase work efficiency, the productivity ratio height reduces operation labour intensity.
In sum, finish forge differential side gear fine finishining precision location clamp of the present invention, compact conformation, flexible operation, accurate positioning, reliable clamping, work-handling is easy, the productivity ratio height, labour intensity is low, and the machining accuracy height guarantees that meshing backlass is even, long service life.
Description of drawings is done further explanation below in conjunction with accompanying drawing and embodiment to the present invention.
Fig. 1 is a structural representation of the present invention.
The specific embodiment is in Fig. 1, finish forge differential side gear fine finishining precision location clamp of the present invention, comprise expander 1, be installed in the spline ringfeder 2 that is used to install axle shaft gear on the expander, be installed in the body 3 on the spline ringfeder inner face, be installed in elastic washer 4 on the expander near the body end face, be pressed against the floating disc 5 on the body end face, the transition disk body 6 that contacts with the floating disc sphere and install near elastic washer, floating disc is fastened to floating disc maintaining body 7 on the transition disk body, is installed in several steel balls 8 between the floating disc and the fine finishining axle shaft gear gear teeth.
Finish forge differential side gear fine finishining precision location clamp of the present invention, said steel ball is 3.
In addition, in Fig. 1, finish forge differential side gear 9, finish forge differential side gear grinding polished surface a, b.
