Background

The steering knuckle is one of important parts of automobile parts, and the processing quality of the steering knuckle has a crucial influence on the performance of the steering knuckle. Currently, there are two ways for finishing the inner cavity of the steering knuckle: the cost of the numerical control machine tool is adopted, and the boring machine is unstable in verticality due to positioning deviation, so that the quality and the production efficiency of a product are seriously influenced.

Disclosure of Invention

In view of the above shortcomings of the prior art, an object of the present invention is to provide a device for finish machining an inner cavity of a vehicle steering knuckle, which is used for solving the problems of high cost, low positioning deviation and low production efficiency in the prior art.

For realize above-mentioned purpose and other relevant purposes, the utility model provides a device of vehicle knuckle finish machining inner chamber, including cutter body, upper bearing, bearing housing, button pin, countersink, lower bearing, jump ring and bearing frame, the upper end of cutter body is No. 4 morse taper shanks for be connected with the drilling machine main shaft, the lower extreme top-down of No. 4 morse taper shanks sets gradually first step, second step and pinhole on the cutter body, the upper bearing install in the lower terminal surface of first step, the bearing housing suit in on the upper bearing, the countersink install in the lower terminal surface of second step, and through passing the button pin of pinhole is fixed, the lower bearing install in the lower extreme of cutter body, lower bearing sliding connection in the bearing frame, the jump ring is packed into be used for in the bearing frame the location of lower bearing.

Optionally, a through hole is formed in the bearing seat, a clamping step and a clamp spring groove are sequentially arranged in the through hole from top to bottom, and the lower bearing is mounted on the lower end face of the clamping step and is positioned through a clamp spring mounted in the clamp spring groove.

The beneficial effect of adopting the above optional scheme is:

1. the device can finish the finish machining of the inner cavity of the automobile steering knuckle on a common drilling machine, can be produced in a single piece and in small batch, can also be produced in large batch, and can ensure the verticality requirement of the upper surface and the lower surface of the inner cavity of the steering knuckle relative to the central line of a main pin hole;

2. compared with a numerical control machine tool, the device saves the processing time, most importantly saves the production cost, and simultaneously improves the production efficiency.
