Description

Technical Field

[0001] The utility model relates to the technical field of copper oil nozzle processing, in particular to a copper oil nozzle processing positioning fixture. Background Art

[0002] In the field of metal processing, copper nozzles are a key component widely used in various precision machinery and equipment, especially in liquid injection systems. Copper nozzles usually consist of two main structural parts: the nozzle end and the connection end. The nozzle end is the key part for accurately controlling the liquid flow and injection direction, while the connection end usually includes threads for firmly connecting the nozzle to other mechanical components.

[0003] Although copper oil nozzles are widely used, their processing faces many technical challenges, especially in positioning and fixing the two key parts. Traditional processing fixtures often cannot meet the positioning and fixing requirements of the nozzle end and the connection end at the same time. This is mainly due to the special structure of the nozzle end, which is usually designed to be small and delicate, requiring very high processing accuracy. When ordinary fixtures fix the nozzle end, they often fail to accurately adapt to its shape, resulting in insufficient processing accuracy or unstable fixation.

[0004] In addition, the threaded part of the connection end also needs special consideration, because any slight error in the processing process may cause thread damage or poor processing, affecting the assembly and performance of the entire product. However, the existing fixture systems on the market mostly focus on fixing one end, and there are few fixture designs that can adapt to the needs of both the nozzle end and the connection end. This results in the need to replace the fixture on the production line or use different machine tools to complete the processing of the corresponding parts separately, greatly reducing production efficiency and economic benefits.

[0005] Traditional solutions to the above problems usually involve using multiple dedicated chucks or processing at different processing stations, which not only increases the equipment investment cost of the work station, but also makes the entire production process cumbersome. Each time the fixture is replaced or the workpiece is transferred to another processing station, valuable production time is consumed and the risk of damage to the workpiece during the transfer process is increased. In addition, each fixture replacement and setting requires precise calibration to ensure the accuracy of the processing, which requires high skills of the operator and increases the complexity of the production process.
