Description

Technical Field

[0001] This utility model relates to the field of liquid level gauge manufacturing technology, and in particular to a positioning fixture for liquid level gauge manufacturing. Background Technology

[0002] Currently, the level of a liquid medium in a container is called the liquid level, and the instrument used to measure the liquid level is called a liquid level gauge. In traditional liquid level gauge manufacturing, especially for plastic liquid level gauges, the body and welding rod are heated by a hot air gun to fuse the two parts together. During this process, the bottom part needs to be positioned to prevent it from shaking during the fusion process and affecting its processing and use.

[0003] Existing positioning devices, when positioning level gauges during processing, are not very effective at protecting the gauges. Excessive clamping force can easily scratch the surface of the level gauges, affecting their quality. Therefore, there is a need to provide a positioning fixture for level gauge production to solve this problem. Utility Model Content
