Description

Technical Field

[0001] The utility model relates to a tool for measuring the lead wire thickness of a compressor sealing gap. Background Art

[0002] During the on-site installation of the compressor unit assembly machine, detecting the comb seal gap is one of the important tasks. The gaps at the upper and lower parts of the seal gap are generally measured by pressing lead wire. The lead wire is generally φ0.3㎜~φ0.8㎜. After the measured part is buckled and pressed, the gap is measured by detecting the thickness of the indentation of the lead wire. Because the comb seal (pulling another seal) sheet is generally 0.3㎜ thick, the indentation is very narrow, and the edge of the measuring tool is required to be high. There are no commonly used detection tools. Generally, auxiliary measurements are performed after the special micrometer is modified. As a measuring tool, the special micrometer must be inspected regularly and is not used frequently, which is not convenient for use on the user's site. Utility Model Content
