Clamp for position changing rocker arm machining

Abstract

The invention discloses a clamp for position changing rocker arm machining. The clamp comprises an engine base, a pressing plate and two supporting plates fixed to the engine base. The two supporting plates fall into one set to be fixed to the engine base. The pressing plate is hinged to one ends of the tops of the supporting plate. The other ends of the tops of the supporting plates are provided with a platform matched with the pressing face of the pressing plate. A groove for placing a rocker arm is formed in the top of each supporting plate. The pressing plate is provided with an arc section matched with the groove and used for clamping and fixing the rocker arm. A drill bushing is arranged at the arc section on the pressing plate. A plurality of drill holes for hole forming are formed in the drill bushing. A compressing handle is arranged on each pressing plate. The clamp for position changing rocker arm machining can effectively improve the drill hole quality and is low in cost.

Description

Technical field [0001] The invention belongs to the field of processing automobile parts, and particularly relates to a fixture for processing a transposition rocker arm. Background technique [0002] The rocker arm is a common part of the automobile. The existing gear selection and shifting rocker arm of the automobile is composed of the gear selection rocker arm, the axle pin, the upper gear spring pin, the shaft, and the displacement bearing. Its structure is more complicated. The arm includes a bearing mounting hole, so it is necessary to make a hole on the rocker arm during processing, and the rocker arm needs to be positioned and clamped when opening the hole. The existing tools for clamping the rocker arm are often installed on machined equipment The chuck has a chuck, a built-in spring, a power switch, a protection device, etc. The clamping and fixing process is to clamp the two ends of the tubular shaft with the chuck on the chuck, and the built-in spring on the chuck is...

AI Technical Summary

Problems solved by technology

[0002] The rocker arm is a commonly used part on the car. The existing car gear selection and shift rocker arm is composed of a gear selection rocker arm, a shaft pin, an upper gear spring pin, a shaft, and a displacement bearing. Its structure is relatively complicated. The arm includes a bearing installation hole, so it is necessary to make a hole on the rocker arm during processing, and the rocker arm needs to be positioned and clamped when opening the hole. The existing tools for clamping the rocker arm are often installed on the machine-added equipment Chuck, there are chucks, built-in springs, power switches, protection devices, etc. on the chuck, the clamping and fixing process is to use the chucks on the chuck to clamp the two ends of the tubular shaft, and at the same time, the built-in spring on the chuck is fixed. However, the clamping and fixing of machining equipment and its chucks is generally only suitable for clamping parts with small lengths, and when the transposition rocker is clamped and fixed by machining equipment and its chucks, it will There will be obvious vibration during the process, which cannot meet the quality of hole making

Moreover, the machining equipment and its chuck are complicated to manufacture and install, and the cost of machining equipment is high.
