Torsion bar pre-twisting equipment

Abstract

The invention discloses torsion bar pre-twisting equipment comprising a base. The base is correspondingly provided with a drive clamp head and a driven clamp head which are used for positioning a torsion bar; the base is provided with a drive mechanism used for driving the drive clamp head to rotate and is provided with a cylinder, and a clamping structure is arranged between the end of the piston rod of the cylinder and the driven clamp head. When the torsion bar is installed, the driven clamp head can be adjusted in a rotating manner, the torsion bar is convenient to install, position and operate, and the pre-twisting operation is high in efficiency.

Description

technical field [0001] The invention relates to the technical field of torsion bar production, in particular to a device for torsion bar pre-twisting. Background technique [0002] After heat treatment, the torsion bar must undergo pre-torsion strengthening treatment according to the use direction of the torsion bar (clockwise and counterclockwise). Plastic deformation occurs during pre-torsion strengthening, and the deformation angle is eliminated to increase the bearing capacity. [0003] Both ends of the torsion bar are spline parts. When pre-twisting the torsion bar, the spline parts at both ends of the torsion bar need to be fixed, one end is fixed, and the other end is rotated. The mechanism positioning of the ratchet principle, because the mechanism of the ratchet principle is limited by the ratchet pin and the ratchet gear when it works, leads to inaccurate positioning and a large positioning angle, and cannot effectively position the 360-degree circle at will, and i...

Problems solved by technology

[0003] Both ends of the torsion bar are spline parts. When pre-twisting the torsion bar, the spline parts at both ends of the torsion bar need to be fixed, one end is fixed, and the other end is rotated. The mechanism positioning of the ratchet principle, because the mechanism of the ratchet principle is limited by the ratchet pin and the ratchet gear when it works, leads to inaccurate positioning and large positioning angles, and cannot effectively position the 360-degree circle at will, and it is difficult to position the two ends of the torsion bar accurately. The low efficiency of the torsion bar pre-twisting operation results in a large error in the pre-twisting strengthening angle, which directly affects the performance of the torsion bar

And the mechanism operation and maintenance of the ratchet principle are inconvenient and inefficient
