Description
Technical Field
The utility model relates to a automobile parts and accessory field of making especially relate to auttombilism room upset is with torsion bar arm of force hole spline tooth broaching processing.
Background
Important parts on the turnover mechanism of the cab of the medium-sized truck are a torsion bar spring and a torsion bar force arm, the turnover angle of the cab is mainly determined by the relative installation angle of the torsion bar spring and the torsion bar force arm, the relative installation angle of the torsion bar spring and the torsion bar force arm is determined by the relative position of inner hole spline teeth of the torsion bar spring and the torsion bar force arm, the relative position of the inner hole spline teeth is determined by the tooth missing angle of the inner hole spline teeth, the inner hole spline teeth and the tooth missing of the torsion bar force arm are pulled out by a broach on a broaching machine, and therefore, the pulled-out inner hole spline teeth and the tooth missing thereof can be ensured to meet the requirements only by making an accurate special broaching clamp. The elasticity of the torsion bar is the main power source for the cab to be overturned, and the torsion bar force arm is the main power transmitter for the cab to be overturned, so the precision of the torsion bar force arm is directly related to the overturning performance of the cab. However, the torsion bar arm has irregular shape, and the geometric precision and the comprehensive performance of the torsion bar arm depend on the machining process of the torsion bar arm to a great extent. However, no related broaching clamp exists so far, and the torsion bar force arm is irregular in shape and is not suitable for machining on a numerical control machining center machine tool. However, the production of automobile parts is a typical mass production mode, and the manufacturing cost becomes an important factor considered by part manufacturers.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an automobile torsion bar arm of force hole spline tooth broaching fixture device solves the problem that the torsion bar arm of force is not convenient for process among the prior art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the inner hole spline tooth broaching fixture for the torsion bar force arm of the automobile is characterized by comprising a positioning disc and a positioning plate fixedly connected with the positioning disc, wherein an arc-shaped groove and a graduated scale are formed in the positioning disc, a positioning shaft is arranged at the tail end of the positioning plate, and a hole is formed in the center of the positioning disc.
Furthermore, the graduated scale is arranged on the outer side of the positioning plate.
Further, the graduated scale is a scale for measuring angles. The measuring range of the graduated scale is 0-360 degrees and includes 0-360 degrees.
Further, a connecting line of the two scale points of 0 degree and 180 degree of the graduated scale is in a horizontal position, and a connecting line of the two scale points of 90 degree and 270 degree is in a vertical position.
Further, the arc-shaped grooves are arc-shaped grooves, and the arc-shaped grooves comprise four groups. The four groups of arc-shaped grooves are symmetrically arranged along the circle center of the positioning disk.
Furthermore, the positioning plate is welded with the positioning plate.
The four sets of arc-shaped grooves 101 are used for fixing the positioning disc on the broaching machine, namely fixing the whole broaching fixture on the broaching machine.
Compared with the prior art, the utility model, following beneficial effect has: the graduated scale is arranged on the positioning disc, so that in actual use, the precision is higher, and mass production is facilitated.
