A cylinder head valve guide hole processing equipment

Abstract

The invention relates to the field of engine manufacturing, in particular to machining equipment for air cylinder cover valve guide pipe holes. The machining equipment comprises a machine body and a sliding frame which is arranged at the top of the machine body in a slidable mode, a cavity with a downward opening is formed in the sliding frame, an inner gear ring is arranged in the cavity end wall, a drilling device used for drilling the guide pipe holes is arranged in the sliding frame, a boss is fixedly arranged on the left side end wall of the sliding frame, a drill bit extending up and down is rotationally arranged in the boss, and the sliding frame moves up and down to drive the drill bit to rotate, so that the machining of the guide pipe holes is realized. According to the machiningequipment for the air cylinder cover valve guide pipe holes, the equipment can be fixed in an oil injector hole in the center positions of the guide pipe holes, so that the drilling and positioning are more convenient; and meanwhile, the equipment can drive the drill bit to rotate around the center of the equipment to drill the holes, so that the equipment precision is improved, the functionalityis high, the stability is good, and the production and popularization are facilitated.

Description

technical field [0001] The invention relates to the field of engine manufacturing, in particular to a cylinder head valve guide hole processing equipment. Background technique [0002] The valve guide holes in the cylinder head are distributed around the fuel injector holes of the diesel engine, and are fixed holes for installing valve guides and valves, etc. During the traditional guide hole machining, the machining track of the tool deviates during the machining process, resulting in the valve guide The machining accuracy of the hole is seriously affected, and even the product is scrapped, and the traditional processing setting is difficult to locate, and the conduit holes cannot be evenly distributed around the engine injector hole, which is poor in practicability and has large limitations, so it is necessary to set A cylinder head valve guide hole processing equipment improves the above problems. Contents of the invention [0003] The purpose of the present invention ...
