Problems solved by technology

With turning, it is difficult to meet the requirements even for fine turning. On the one hand, the method of grinding is inconvenient to clamp on the inner circular mold bed due to the irregular shape of the steering knuckle. On the other hand, the production efficiency of grinding is low and the cost is too high. high

Embodiment Construction

[0039] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] like figure 1 As shown, a tooling for processing steering knuckle bearing holes, the tooling includes a fixture, and the fixture includes a base plate 1, a positioning shaft 2, a support member, a circumferential positioning clamping device 4, an auxiliary pressing device and a pressing device.

[0041] The bottom plate 1 is a rectangular block, and the center of the bottom plate 1 is provided with a through hole X.

[0042] The positioning shaft 2 is a stepped shaft with two shaft sections, the lower shaft section 2a and the upper shaft section 2b are arranged concentrically, and the upper shaft section 2b matches the cover mounting hole 7h on the steering knuckle 7 to be processed and A through hole D2c is concentrically formed on the top surface thereof.

[0043] The support components include a support cylinder A3 a...

Abstract

The invention discloses a machining tool and a machining method of a steering knuckle bearing hole. The tool comprises a fixture; the fixture includes a baseplate, a positioning shaft, a support part, a peripheral positioning clamping device, an auxiliary pressing device and a pressing device; the auxiliary pressing device is arranged in a tool magazine of a machining center; and a cutter clamping device on a main shaft of the machining center is used for automatically clamping to press on a steering knuckle to be machined in the fixture. The invention further designs the machining method corresponding to the tool. The tool and the method realize high-precision and high-efficiency machining of the steering knuckle bearing hole, integrate machining of a fender fixed hole end surface, a brake mounting hole end surface, an ABS mounting surface and a hole, reduce the clamping times, save the time, and improve the efficiency.

Description

technical field [0001] The invention relates to the field of automobile parts processing, in particular to a processing tool and a processing method for steering knuckle bearing holes. Background technique [0002] The steering knuckle is one of the important parts in the steering axle of the car. Its function is to transmit and bear the front load of the car, support and drive the front wheel to rotate around the kingpin to make the car turn. In the driving state of the car, it bears variable impact loads, so its precision requirements are often high. like Figure 9 The steering knuckle shown has a bearing hole diameter of φ90 and a depth of 54. Cylindricity requires 0.015. With turning, it is difficult to meet the requirements even for fine turning. On the one hand, the method of grinding is inconvenient to clamp on the inner circular mold bed due to the irregular shape of the steering knuckle. On the other hand, the production efficiency of grinding is low and the cost...
