Embodiment Construction

[0010] Such as figure 1 and figure 2 As shown, the present invention provides a kind of cross shaft machining fixture, and it comprises clamp body 1, and the manufacturing material of clamp body 1 is Crl2 steel, and clamp body 1 is cylindrical, is evenly provided with eight screw on the upper surface of clamp body 1. The hole 4 is symmetrically provided with four V-shaped grooves 2 along the cross-shaped direction on the clamp body 1, and four notches 3 are evenly provided on the inner side of the clamp body 1, and each two adjacent V-shaped grooves 2 are provided with There is a counterbore3.

[0011] When the present invention is used, the chuck on the main shaft of the ordinary lathe is removed first, and then the fixture is installed, and the fixture is installed on the main shaft L of the ordinary lathe through hole positioning and connecting bolts, and then the four axes of the cross shaft are respectively placed in a V shape. In slot 2, press firmly. Then the cross ...

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 [0001] The invention relates to the field of automobile parts processing, in particular to a cross-axis processing fixture. Background technique [0002] The cross shaft is a key part in the assembly of the universal joint of the automobile transmission shaft. The verticality, symmetry and flatness of each axis of the four journals of the cross shaft are very high, and its processing tightness directly affects the transmission of the universal joint. balance and service life. The current processing procedures are normalizing, turning, broaching, quenching, and grinding the outer circle. In order to ensure the processing quality, it is necessary to make a special [0003] The cross axis clamp used. Due to the special shape of the cross shaft in the turning section, the existing fixtures are inconvenient to clamp and the quality cannot be effectively controlled. Therefore, a special fixture is urgently needed to ensure the processing quality of the cross shaf...
