Description

Steering knuckle turning clamp

Technical Field

Background

The steering knuckle is one of the important parts in the steering axle of the automobile, and has the function of transmitting and bearing the front load of the automobile, supporting and driving the front wheels to rotate around the main pin so as to steer the automobile. In the driving state of the vehicle, it is subjected to a variable impact load, and therefore, it is required to have a high strength. When the steering knuckle is turned into a center hole, the minimum wall thickness is specified for a bearing hole, a brake mounting hole, a knuckle arm taper hole and a long-short end taper hole of the steering knuckle, so that great difficulty is caused to a machining process. In the past, when the outer circle of a blank of the bearing hole is used for positioning during steering section processing, the wall thicknesses of the multiple positions cannot be considered simultaneously, and because the outer circle of the blank has errors, the wall thickness uniformity of the bearing hole can be influenced, and further the minimum wall thicknesses of other positions cannot be guaranteed. The positioning shaft center of the knuckle bearing hole with higher precision can be manufactured by using a blank, but another problem is brought along with the problem that the inner hole of the bearing hole blank needs to be turned, so that the positioning shaft needs to be positioned by the knuckle and then is withdrawn out of the inner hole of a product, and the interference with a cutter is avoided. Therefore, how to design the clamp is a difficult problem on the basis of ensuring the minimum wall thickness of a plurality of positions on the steering knuckle, and the problem that the clamp cannot process the steering knuckle due to the interference of the clamp on the tool is solved.
