AI Technical Summary
Traditional cylinder head spraying devices have inconvenient nozzle position adjustment, making it difficult to flexibly adjust according to the size and shape differences of different cylinder head models, resulting in uneven spray coverage of the cylinder head surface and affecting quality.
The nozzle is driven to move back and forth by a first linear motor and to move left and right by a second linear motor. The relative position of the nozzle and the cylinder head can be adjusted by combining the observation port, thus achieving flexible adjustment.
It enables flexible adjustment of the nozzle and cylinder head position, ensuring uniform spray coverage of the cylinder head surface and improving the quality and performance of the cylinder head.

Description
Technical Field
[0001] This utility model relates to the field of spray device technology, specifically a cylinder head spray device. Background Technology
[0002] During the manufacturing process of engine cylinder heads, spray treatment is often required, and this process plays a crucial role in the quality and performance of the cylinder heads.
[0003] However, the nozzle position adjustment of traditional cylinder head spraying devices is inconvenient: the nozzle position of previous spraying devices is usually fixed or has limited adjustment methods, making it difficult to flexibly adjust the relative position between the nozzle and the cylinder head according to the size and shape differences of different cylinder head models. This results in the spray not being able to evenly cover the cylinder head surface, and some areas being insufficiently sprayed, failing to meet process requirements and affecting the quality of the cylinder head. Therefore, it is necessary to develop a cylinder head spraying device. Utility Model Content
