Deep hole machining auxiliary tools, machining process and air cylinder cover oil drainage hole machining process

Abstract

The invention provides deep hole machining auxiliary tools, a machining process and an air cylinder cover oil drainage hole machining process and belongs to the technical field of mechanical machining. According to the deep hole machining auxiliary tools, the intersecting positions of deep holes are provided with short holes communicating with the deep holes. The auxiliary tools are arranged to beof rod piece structures installed in the short holes and comprise stretching-in portions in clearance fit with the short holes and connection portions pre-tightened and fixed to the short holes. Theprinciple of the deep hole machining process is the same as that of the air cylinder cover oil drainage hole machining process and comprises the steps that the machining auxiliary tools are installedin the short holes, a workpiece is positioned and clamped, the coordinate systems of the deep holes are determined, the deep holes are drilled out at the two ends of the workpiece, and the machining auxiliary tools in the short holes are taken out. The deep hole machining auxiliary tools, the machining process and the air cylinder cover oil drainage hole machining process have the beneficial effects that the problem of unilateral stress in the cutting process is avoided, the eccentric distance is reduced, the service life of a cutter is prolonged, the manufacturing cost is lowered, the machining quality is guaranteed, the processes are simple in operation, the machining auxiliary tools can be taken out without damaging the workpiece, and the auxiliary tools are more convenient and efficient to use.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a deep hole processing auxiliary tool, a processing technology and a cylinder head oil drain hole processing technology. Background technique [0002] At present, deep hole processing is an important branch of mechanical processing, and deep hole drilling is an important component of deep hole processing. The requirements for processing accuracy and stability are getting higher and higher, but in the processing of intersecting hole systems, short When the hole and the deep hole are connected and the axes of the two holes are in different planes, when processing the deep hole on the basis of short hole processing, the processing of the deep hole usually uses a gun drill. When the long diameter of the deep hole is relatively large, due to the short hole and the deep hole There is a certain eccentric distance between the holes. If the deep hole is processed directly on...

Problems solved by technology

[0004] In order to solve the above technical problems, the present invention provides a deep hole processing aid, processing technology and cylinder head oil drain hole processing technology, the purpose is to solve the problem that the center position cannot be positioned, It is easy to run off, and even lead to the scrapping of the workpiece and the breakage of the tool. By designing a deep hole processing auxiliary tool, it is applied in the processing technology of deep holes and the processing technology of the cylinder head oil drain hole, which avoids the cutting process. The problem of unilateral force greatly reduces the eccentricity, ensures the processing quality, improves the service life of the tool, saves the workpiece, reduces the manufacturing cost, and is easy to operate. This processing aid can be used without damaging the workpiece. Take out under the premise, convenient and efficient
