Problems solved by technology

But so far there is no related fixture. Due to the irregular shape of the torsion bar arm, it is not suitable for machining on the CNC machining center machine tool. It can only be milled by scribing. Not only the machining accuracy and machining efficiency are low, but also the manufacturing high cost

Abstract

The invention discloses a milling fixture for an automobile torsion bar moment arm thread end surface. The milling fixture comprises an upper bottom plate, a lower bottom plate and a supporting plate,the upper bottom plate is fixedly connected with the lower bottom plate, the lower bottom plate and the upper bottom plate are fixed to a working table, the supporting plate is fixedly connected withthe upper bottom plate, a pre-tightening core shaft and a positioning core shaft are arranged on the lower bottom plate, an eccentric wheel is arranged on the pre-tightening core shaft, a handle shank is arranged on the eccentric wheel, the eccentric wheel is in adjustable connection with the pre-tightening core shaft, and a positioning column is arranged on the upper bottom plate. Through the cooperation of the pre-tightening core shaft and the positioning core shaft, the problem of the placement of different angles of a torsion bar moment arm is solved, the clamping action of the torsion bar moment arm with different bending radians is realized through the rotation adjustment of the eccentric wheel, and the stability and precision of the integral machining operation are improved.

Description

technical field [0001] The invention relates to the field of manufacturing auto parts and accessories, in particular to the milling process of the threaded end face of a torsion bar force arm for turning over an automobile cab. Background technique [0002] The important components on the turning mechanism of medium truck cab are torsion bar spring and torsion bar arm. The turning angle of the cab is mainly determined by the relative installation angle of torsion bar spring and torsion bar arm. The torsion bar spring and torsion bar arm After the relative installation angle is determined, it is fixed by the fastening screw in the threaded hole of the torsion bar arm, and whether the fastening screw can fix the torsion bar spring for a long time is related to the relative position of the threaded hole of the torsion bar arm. Whether the drilling of the threaded hole of the arm is accurate, the premise is that the milling of the thread end face must be accurate. The elastic f...
