Embodiment

[0037] Car round shaft part clamping tool, reference Figure 1 - Figure 5As shown, including two-to-one or away from the V-shaped block 1, the two V-shaped block 1 is adjacent or away from or away from the one-to-one side of the two V-shaped block 1 extends two and one guide 36. The blending block 7, the two mating block 7 end is convex with the slider 4 in which the guide rail 36 is embedded in the guide slip, the cross section of the slider 4 and the guide rail 36 guide is "dove tail" or "inverted T shape" A nut 8 opposite to the threaded direction is fixed to the two-fitting block 7, and two housing 9 is fixed at both ends of the guide rail 36, and the rotation between the bearing housing 9 is provided with the reverse screw 10 that cooperates with the two screw 8, reverse direction. The rotation of the screw 10 is controlled by a motor 11 fixed to the guide rail 36, since the two screw portions are in opposite to the reverse wire rod 10, as the motor 11 is rotated, the two scre...

Abstract

The invention relates to the technical field of automobile part production auxiliary equipment, and discloses an automobile circular shaft part clamping tool which comprises two V-shaped clamping blocks capable of getting close to each other or getting away from each other, the two V-shaped clamping blocks get close to each other or getting away from each other is controlled by a driving mechanism, and the V-shaped clamping faces of the V-shaped clamping blocks are provided with two adsorption pieces which are in point contact with circular shaft parts all the time. An elastic adsorption body elastically abutting against the surface of the circular shaft part is arranged in the concave center of the V-shaped clamping face in a protruding mode, the adsorption piece comprises a suction cup and a first air bag arranged in the center of the suction cup in an expanding mode, and an adsorption pipe is arranged in the center of the elastic adsorption body. A linkage mechanism for driving the negative pressure of the adsorption pipe to be increased after the first air bag is extruded is arranged in the V-shaped clamping block, a desorption mechanism for supplementing air to the first air bag is arranged on the adsorption piece, and a reset mechanism for driving the first air bag to reset and the adsorption pipe to recover the normal pressure is arranged in the V-shaped clamping block. The clamping firmness can be obviously improved, and discharging is convenient and fast.

Description

Technical field [0001] The present invention relates to the technical field of automotive parts production assistance equipment, in particular a car coaxial part clamping tool. Background technique [0002] In the production of car production, the circular shaft part involved, for example, the axle is present in the production, and it is necessary to apply to the clamp and CNC lathe in production. [0003] The clamp structure of the existing circular shaft workpiece can refer to a hydraulic self-central fixture of a hydraulic self-designed disclosure of China's patent No. CN208945673U, including two V-shaped blocks that are close to or away, respectively, two V-shaped blocks, respectively. There are two up and down racks, and there is a gear to engage the two tooth strips, and the two V-shaped clamps can be achieved simultaneously or away from the axial part of the binalxial part of different diameters. . [0004] However, there is only a squeezing force between the above V-shape...
