Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal detection equipment, in particular to a sheet metal hole positioning detection jig. Background Art

[0002] Sheet metal punching is a basic process in sheet metal processing. It refers to the process of making holes of the required shape and size on metal sheets through a stamping process. Sheet metal punching has the advantages of high processing efficiency, high precision, and low cost, and is suitable for a variety of metal materials, such as steel plates, aluminum plates, copper plates, etc.

[0003] After punching the sheet metal, the hole size needs to be tested to avoid large errors in the hole size that affect the installation of the sheet metal material. Existing sheet metal parts use a conical cylindrical measuring block to insert into the hole for hole testing. If the measuring block cannot be inserted into the hole to the specified depth, the hole is too small; if the measuring block is inserted too deep into the hole, the hole is too large.

[0004] However, the hole sizes on sheet metal parts are not completely uniform, and manpower is required to replace different measuring blocks to detect the holes. However, replacing the measuring blocks is not only complicated, but also wastes a lot of time, affecting the efficiency of sheet metal hole detection. Utility Model Content
