Description

Technical Field

[0001] This utility model relates to the field of annular spinneret processing, and in particular to a tool for adjusting the concentricity of annular spinnerets. Background Technology

[0002] A search of Chinese patents revealed publication number CN212019485U, which discloses a tool for adjusting the concentricity of an annular spinneret. The tool includes an adjusting rod and a microscope positioned above an annular groove in an annular spinneret clamp. The adjusting rod comprises two rods, an adjusting element for simultaneously moving the two rods away from or towards each other, and two fixing sleeves symmetrically fixed to the inner ring of the annular spinneret clamp. This invention allows for convenient adjustment of the concentricity of the annular spinneret within the clamp, is simple to operate, highly efficient, and eliminates the need to adjust the position of the drilling equipment during subsequent drilling.

[0003] In summary, this adjustment tool is inconvenient to use. When using it, two fixing sleeves need to be symmetrically fixed to the inner ring, then the first and second screws need to be loosened, and the adjusting member needs to be rotated up and down until the tail ends of the two rods contact the annular spinneret. Then, the first and second screws need to be tightened, and finally, the rods need to be rotated up and down for adjustment. This operation is cumbersome, increases workload, reduces adjustment efficiency, and is also inconvenient to store. As the tool is a single unit, it occupies a large space when stored, reducing its practicality. To solve these problems, we propose an annular spinneret concentricity adjustment tool. Utility Model Content

[0004] The purpose of this invention is to provide a tool for adjusting the concentricity of an annular spinneret, which has the advantages of being easy to adjust and easy to store.

This utility model achieves the purpose of easy adjustment, reduces workload, and improves adjustment efficiency by rotating the rotating block on the second rotating shaft to move the bottom telescopic rod to abut against the inner wall of the spinneret clamp, so that the tool is in the center of the spinneret clamp. Then, the rotating head on the first rotating shaft is rotated to make the top telescopic rod abut against the inner wall of the annular spinneret, so that it is in the same position as the center of the spinneret clamp.

[0023] 2. This utility model uses a movable sliding cylinder to move the triangular groove. The movement of the triangular groove causes the locking rod to disengage from the locking hole under the action of the second spring, allowing the adjusting rod to be removed and stored. This method facilitates storage, improves practicality, and makes the product convenient to use. Attached Figure Description
