Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cylinder head processing, in particular to a clamping device for processing an engine cylinder head. Background Art
[0002] The cylinder head is one of the most important parts in a diesel engine. After the cylinder head and the cylinder form a closed environment, they can form a combustion chamber to withstand high-temperature and high-pressure combustion gas. In addition, the cylinder head is also equipped with intake and exhaust channels, fuel injection holes and irregular cooling water channels. In the process of machining the cylinder head, in order to ensure the stability of the machining, a clamping device is required to clamp the cylinder head.
[0003] During use of the existing clamping device, the cylinder head is usually placed on the surface of the clamping table, and the hydraulic equipment is used to push the clamping plate to move inward to fit the surface of the cylinder head, thereby completing the clamping of the cylinder head. However, in actual use, since both sides of the cylinder head need to be processed, when one side is processed, the staff needs to flip it over to the other side for processing. Under the premise of flipping, the clamping plate needs to be separated from the surface of the cylinder head. This wastes the staff's time and increases the staff's workload. For this reason, we propose a clamping device for engine cylinder head processing to solve the above problems. Utility Model Content

[0012] As a preferred solution, second cylinders are fixedly connected to both sides of the bottom of the inner cavity of the processing table, and the top of the second cylinder is closely connected to the bottom of the shell.
[0013] Through the above technical solution, the second cylinder is used to facilitate the upward movement of the shell, which in turn pushes the moving rod to move, and the upward movement of the moving rod pushes the fixed plate to move downward, and the fixed plate drives the clamped cylinder head to move upward, which is convenient for the subsequent flipping adjustment work, thereby improving the stability of the adjustment.

[0018] As a preferred solution, a bearing body is fixedly connected to the inner side of the fixed plate, and the surfaces of the rotating rod and the movable rod are both rotatably connected to the inner cavity of the bearing body.
[0019] Through the above technical solution, the stability of the rotation of the movable rod is improved through the bearing body.
