Problems solved by technology

[0003] Due to the high precision of the tappet working environment, the surface of the tappet needs to be finished during processing. The existing processing method usually uses a grinding wheel to polish the surface of the tappet. However, this grinding method requires workers Manual operation consumes a lot of manpower and time, the grinding method is cumbersome, and the work efficiency is low. At the same time, the surface roughness of the tappets polished by this method is poor, and the surface circumference of the tappets is poor, resulting in Poor column machining quality

Abstract

The invention relates to the technical field of tappet machining, in particular to a tappet surface finish machining machine tool which comprises an arch-shaped fixing frame. A lead screw is transversely and rotationally installed in the arch-shaped fixing frame, the thread turning directions of the left side and the right side of the outer wall of the lead screw are opposite, threaded sleeves are arranged on the left side and the right side of the lead screw in a threaded mode, a spring is installed between the two threaded sleeves, and the spring is arranged on the outer side of the lead screw in a sleeving mode. A first guide rail is arranged at the tops of the two threaded sleeves in a sliding manner, and the first guide rail is mounted on the lead screw. The tappet surface finish machining machine tool can realize surrounding type automatic grinding treatment on the surface of a tappet, and the grinding mode is coating type surface contact grinding, so that comprehensive and uniform grinding treatment on the surface of the tappet is facilitated, the grinding precision is effectively improved, the surface circularity of the tappet is improved, the surface roughness of the tappet is reduced, meanwhile, manpower and time are saved, the grinding mode is simplified, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tappet processing, in particular to a tappet surface finishing machine tool. Background technique [0002] As we all know, the valve-type valve train consists of two parts: the valve group and the valve train group. The tappet is a main component of the valve drive group except the camshaft. In the valve drive group, the tappet is the follower of the cam. Its function is to transmit the motion and force from the cam to the push rod or valve, and at the same time It also bears the lateral force exerted by the cam and transmits it to the body or cylinder head. [0003] Due to the high precision of the tappet working environment, the surface of the tappet needs to be finished during processing. The existing processing method usually uses a grinding wheel to polish the surface of the tappet. However, this grinding method requires workers Manual operation consumes a lot of manpower and time, the grinding met...
