Description

Technical Field

[0001] The utility model relates to the field of cylinder head processing tooling, in particular to a cylinder head processing tooling for a ship diesel engine. Background Art

[0002] The cylinder head is one of the key components of the engine. It is installed on the upper part of the cylinder block and together with the cylinder wall and the top of the piston constitutes the combustion chamber. The main function of the cylinder head is to seal the cylinder and withstand the thermal and mechanical loads of high-temperature and high-pressure combustion gas. It is usually made of gray cast iron or aluminum alloy and has good thermal conductivity and strength.

[0003] During the processing of the cylinder head, tooling equipment is needed to fix it to facilitate drilling and other processing steps. However, the existing tooling is not suitable for processing cylinder heads of different specifications. Because of their different specifications, their heights and diameters are different, it will cause frequent replacement of fixed tooling, which is very troublesome. Utility Model Content

[0004] Based on the above description, the utility model provides a ship diesel engine cylinder head processing tooling to solve the problem that the existing tooling equipment used for cylinder heads is not well adapted to cylinder heads of different specifications.

[0005] The technical solution of the utility model to solve the above technical problems is as follows: a ship diesel engine cylinder head processing tooling includes a base assembly;

[0006] A cylinder cover is arranged on the top of the base assembly, and mounting assemblies are installed around the top surface of the base assembly;

[0007] The mounting assembly includes a mounting plate, a slider, a threaded rod, a fixing plate, a sleeve, a fixing rod, a limit plate and a baffle;

[0008] The threaded rod thread passes through one end of the fixing plate and is connected to the side of the mounting plate through a bearing. The baffle is fixedly mounted on the bottom of the limiting plate, and the limiting plate is mounted on the top of the mounting plate through a sleeve.

[0009] Furthermore, the base assembly includes a base, a stepped top seat and a slide groove, the stepped top seat is fixedly installed on the middle part of the top surface of the base, and the slide groove is located around the top surface of the base.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the number of the slide grooves is four, the four slide grooves are evenly distributed on the top surface of the base, and the inner wall of the slide groove is movably connected to the outer wall of the slider.

[0012] Furthermore, the slider is fixedly mounted on the bottom of the mounting plate, and one end of the slider away from the mounting plate is movably fitted with the inner wall of the slide groove, and the bottom of the mounting plate is movably fitted with the top surface of the base.

[0013] Furthermore, the bottom of the fixing plate is fixedly connected to the top surface of the base, and the side wall of the fixing plate is threadedly connected to the surface of the threaded rod, and the twisting of the threaded rod pushes the mounting plate to slide on the base.

[0014] Furthermore, a thread groove is formed on the surface of the fixing rod, and the fixing rod is threadedly connected to the side wall of the sleeve, and one end of the fixing rod passes through the sleeve and fits onto the side wall of the mounting plate.

[0015] Furthermore, the cross section of the mounting plate is designed to be a rectangle, the cross section of the sleeve is designed to be a rectangular ring, and the baffle plate and the limiting plate are perpendicular to each other.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0017] 1. The utility model arranges a mounting assembly on the base assembly, which facilitates the use of the threaded rod to push the mounting plate to slide, so that the baffle plate and the limit plate on the sleeve are fitted to the cylinder head to limit and fix the cylinder head. The adjustable fixing method is also suitable for cylinder heads of different specifications. With the stepped top seat, the cylinder heads of different specifications can be stabilized.

[0018] 2. By allowing the sleeve to be movably mounted on the mounting plate and allowing the fixing rod to pass through the sleeve, it is convenient to adjust the height of the sleeve, so that the baffle plate and the limit plate can fit and limit the cylinder heads of different specifications, thereby further improving the stability of the fixing of the entire mounting assembly.
