Problems solved by technology

[0004] The method of machining the cooling water hole on the cylinder head by the CNC machining center in the prior art has the advantages of high machining accuracy, but has the disadvantage of high production cost, because the processing of the cooling water hole on the cylinder head requires a huge amount of CNC machining center, not only waste of resources, but also the processing quality of the cooling water hole on the cylinder head does not match with other equipment.
[0005] In the prior art, the method of processing the cooling water hole of the cylinder head by using ordinary process equipment fixtures and drilling machines mainly has the disadvantages of long pre-drilling preparation period, complicated angle adjustment and unsatisfactory processing quality.

Embodiment

[0053] The practical application of a three-dimensional operating platform for drilling of the present invention will be described in detail below by taking the processing of the cylinder head cooling water hole of a large marine diesel engine as an example.

[0054] The cylinder head of a large marine diesel engine has a cylindrical structure, and 30 cooling water holes should be processed on the ring at the end, and the cooling water holes should be evenly distributed on the end ring. The axis is at an angle of 40 degrees, which requires high machining accuracy when drilling. As shown in FIG. 11 , FIG. 11 is a schematic diagram of the operation of an embodiment of a three-dimensional operation platform for drilling according to the present invention.

[0055] First, fix the three-dimensional operation platform of the present invention on the workbench of the processing machine tool, fix the base 1 of the three-dimensional operation platform with the anchor bolts of the machi...

Abstract

An operation platform for drilling hole is composed of base, central shaft, worm-gear set, platform supporting parts, platform and locating disc. It can be used for drilling machine for drilling complex and accurate holes.

Description

technical field [0001] The invention relates to a diesel engine, in particular to a three-dimensional operation platform for drilling cooling water holes of the cylinder head of the diesel engine. Background technique [0002] The cylinder head of a diesel engine is an important workpiece in a diesel engine. It bears the high temperature of fuel combustion and the huge combustion explosion pressure during its work. In order to reduce the working temperature of the cylinder head, a plurality of cooling water holes are arranged on the cylinder head to cool the high temperature cylinder head during operation. The cooling water holes on the cylinder head are distributed in the circumferential direction of the top of the cylinder head according to the design requirements, and form a certain angle with the central axis of the cylinder head. The different processing and drilling methods of the cooling water holes have a great impact on the quality of the cylinder head. Impact. ...
