Problems solved by technology

[0002] The big end of the connecting rod of a marine engine has four bolt holes. At present, these four bolt holes are generally processed on a horizontal machining center, and the processing is carried out one by one. It is cumbersome, and the processing efficiency is extremely low, which greatly increases the production cost of the connecting rod

Embodiment Construction

[0021] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0022] Such as image 3 , Figure 4 , Figure 5 As shown, the tooling is composed of a positioning base plate 7, a guide hole positioning plate 8, a first compression module 9, a first compression screw 10, a second compression module 11, a second compression screw 12, and side positioning pins 13. Wherein, positioning base plate 7 is rectangular, guide hole positioning plate 8 is set at the left end of positioning base plate 7, and this guide hole positioning plate 8 is perpendicular to positioning base plate 7, and guiding hole positioning plate 8 is preferably " U " shape, and guiding hole positioning plate 8 The lower end and the left end of the positioning base plate 7 are abutted against and fixed. Two upper and lower guide sleeve holes 8a are respectively opened on the upper parts of the left and right ends of the guide hole positioning plate 8, and...

Abstract

The invention discloses a machining method for deep hole of marine engine connecting rod. The method comprises the following steps: Firstly, a tool is installed for positioning the connecting rod on the work table of the machine tool, and a total of four main axes is arranged on the machine tool, each of which is provided with a gun drill. Secondly, the connecting rod to be processed is fixed to the tooling. Thirdly, the table is fast moved to the first station, so that the first spindle and the second spindle on the gun drill slowly into the tooling of the guide sleeve hole, while processing two lower bolts of connecting rod through the hole. Fourthly, the table is fast moved to the second station, so that the third spindle and the fourth spindle on the gun drill slowly into the tooling guide sleeve hole, while processing two head bolts of connecting rod through the hole. Fifthly, when processing is completed, the table is moved back to the reference point. The invention can complete all the processing, and the clamping operation is simple, and the processing efficiency is high, and the invention also can reduce the processing cost twice, and the dimensional accuracy, the shape and position tolerance are easy to be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing technology, and in particular relates to a method for processing a plurality of deep holes in a connecting rod of a marine engine at one time. Background technique [0002] The big end of the connecting rod of a marine engine has four bolt holes. At present, these four bolt holes are generally processed on a horizontal machining center, and the processing is carried out one by one. It is cumbersome, and the processing efficiency is extremely low, which greatly increases the production cost of the connecting rod. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a deep hole machining method for a marine engine connecting rod. [0004] The technical scheme of the present invention is as follows: a deep hole processing method for a marine engine connecting rod, whi...
