Description

Technical Field

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

[0002] In the mechanical processing industry, the positioning tool for sprayer assembly refers to a process equipment used in the sprayer assembly process to ensure that each component (such as nozzle, water pipe, motor, etc.) can be accurately and stably installed in the specified position. Among them, the positioning assembly of the sprayer nozzle and water pipe is an important process, which is directly related to the use effect and efficiency of the sprayer.

[0003] In the positioning and assembly process of traditional sprinkler heads and (water pipe) sprinkler head joints, some movements need to be achieved through the intermittent operation of some mechanisms. At the same time, during multiple assembly processes, positioning errors may gradually accumulate, resulting in a decrease in the accuracy of the final product.

[0004] Based on this, we propose a positioning fixture for sprayer assembly, which has high precision in positioning the nozzle and nozzle joint, and in manipulator clamping, placement and tightening. It also uses a reciprocating operating mechanism to achieve non-stop conveying and synchronous operation, thus increasing the service life of the equipment and improving production efficiency.
