Fixture for machining knuckle backing pin hole

Abstract

The invention relates to a fixture for machining a knuckle backing pin hole, wherein a fixture body (1) is provided with a knuckle (3); a pressure plate (4) is arranged on a main shaft of the knuckle (3) and a V-shaped block (7) is arranged below the main shaft of the knuckle (3); a location block (5) is arranged between the large surface of the knuckle (3) and the fixture body (1); the fixture body (1) is provided with a location pin (6) and a hydraulic cylinder (9), and a piston of the hydraulic cylinder (9) is connected with the pressure plate (4); the pressure plate (4) is provided with an adjustment bolt (8) which is arranged on the fixture body (1); the adjustment bolt (8) is provided with a spring (10); and a guiding bracket (2) is internally provided with a rolling bearing (11) in which a guiding sleeve (12) is arranged. By adopting one-off fixing with small error, the work efficiency is improved, the production cost of the enterprise is reduced, and the machined product has high precision.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture for processing steering knuckle support pin holes. Background technique [0002] At present, the machining of the steering knuckle pin hole usually involves installing multiple sets of fixtures on multiple machine tools, and the process sequence of drilling, expanding, and reaming is often used when machining the steering knuckle pin hole. The disadvantages of this process arrangement are mainly: there are many types of cutting tools and large consumption, and there are many processing steps at the same time, resulting in many factors affecting product quality during the processing process, and it is difficult for the product to meet the requirements of the drawing. The labor intensity of the operator is high, which increases the production cost of the enterprise, and the work efficiency is low. Multiple clamping increases the cumulative error, and the quality of the processed product is no...

The disadvantages of this process arrangement are mainly: there are many types of cutting tools and large consumption, and there are many processing steps at the same time, resulting in many factors affecting product quality during the processing process, and it is difficult for the product to meet the requirements of the drawing. The labor intensity of the operator is high, which increases the production cost of the enterprise, and the work efficiency is low. The accumulated error is increased by multiple clamping, and the quality of the processed products is not suitable for guarantee.
