Description

Technical Field

[0001] The utility model relates to the technical field of internal combustion engine cylinder head processing, in particular to a cutting device for cylinder head production. Background Art

[0002] An internal combustion engine is a power machine. It is a thermal engine that burns fuel inside the machine and converts the heat energy released directly into power. The cylinder head is an important part of the internal combustion engine. It is located on the upper part of the cylinder block and is responsible for sealing the cylinder and forming the combustion chamber. The cylinder head is often in contact with high-temperature and high-pressure fuel gas, so it needs to withstand large thermal and mechanical loads. In the production process of the cylinder head, it is usually necessary to accurately adjust the shape and size of the cylinder head according to the design requirements to adapt to a specific model of engine, so a cutting device for cylinder head production is required.

[0003] According to the search, Chinese patent literature, announcement number: CN220462421U, discloses a cutting device for the production of internal combustion engine cylinder heads, in which the gear a connected to the rotating shaft is driven to rotate by the rotation of the motor b, and the gear a is meshed with the groove provided on the outer surface of the moving frame. The rotation of the gear a can drive the moving frame to move backward along the slide rod close to the cutting knife, and at the same time, the cylinder head on the cutting table at the upper end of the moving frame moves backward close to the cutting knife for cutting, the rotation of the motor c in the moving frame drives the gear b connected to the rotating shaft to rotate, and the gear b is meshed with the gear c installed on the screw rod, and the continuous rotation of the gear b can drive the gear c and the screw to rotate, and the screw rod is threadedly connected to the slider at the bottom of the slide, and the rotation of the screw can drive the slide to move left, thereby driving the cylinder head on the cutting table to move left, and the extension of the hydraulic cylinder in the slide can drive the connected workbench to move up, and the moving up of the workbench drives the cutting table to move up, which can drive the cutting table to move forward and backward, left and right, and up and down. However, in actual use, the device cannot clearly and effectively install and fix the cylinder head, which will affect its accuracy and product quality during cutting. In addition, when the cutting knife cuts the cylinder head, high-temperature sparks will be generated, which are sufficient to ignite combustible materials that come into contact with it. However, the device does not have corresponding protective measures, so it is dangerous to the operator. Utility Model Content
