Description

Technical Field

[0001] The utility model belongs to the technical field of nozzle processing, and in particular relates to a rotatably adjustable positioning tool for nozzle processing. Background Art

[0002] The nozzle surface needs to be ground and polished during processing. In order to prevent the nozzle adapter from moving during processing, a special fixture is needed to fix it.

[0003] Although the existing nozzle processing fixture can meet normal use requirements, the fixing fixture needs to be manually screwed on the threaded rod during use, and the threaded rod drives the clamping plate to move to clamp the nozzle to complete the clamping and fixing of the nozzle. However, since the number of nozzles is large during production and processing, it is necessary to manually screw the threaded rod frequently to clamp and loosen the nozzle, which makes the operation more troublesome when processing the nozzle and reduces the processing efficiency of the nozzle.
