Machining tool device used for automobile rocker arm

Abstract

The invention provides a machining tool device used for an automobile rocker arm. The machining tool device comprises the rocker arm, a rotating hole and press plates. A rotary disc of an indexing rotary platform is fixedly connected with a support. The upper end face of the support presses the rocker arm through the two press plates. The front end face of the support is slidably connected with an auxiliary plate and is fixedly connected with the support through two fastening bolts. The rotating hole is formed in the middle of the rocker arm. The left side and the right side of the rocker arm are provided with connecting holes respectively. Machining faces of the rocker arm include the hole diameter of the rotating hole, two end faces of the rotating hole, the hole diameters of the two connecting holes and the end faces of the connecting holes. By means of one tool, all machining faces of the rocker arm are machined at one time, the former way which needs frequent loading and unloading as well as distributed machining is changed, operation is reduced, the preparation workload is relieved, the working efficiency is improved, errors caused by secondary alignment are avoided, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing devices, and more specifically relates to a processing tooling device for a rocker arm of an automobile. Background technique [0002] As a common component of automobiles, the car rocker arm has a large demand. In the production of the car rocker arm, the car rocker arm is first produced into blanks by forging, and then the rotating holes and connecting holes of the car rocker arm are machined. The end face is milled, and the inner hole is bored. The existing processing method is generally divided into multiple processes for sequential processing. [0003] Based on the above, and in combination with the equipment in the prior art, it is found that during the processing of the automobile rocker arm, it needs to be disassembled and assembled many times, and the processing is divided into parts, the operation is troublesome, the productivity is low, and there will be alignment errors d...
