Description

Technical Field

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

[0002] Currently, sheet metal parts on the market are usually produced by stamping technology. During the forming process, it is necessary to ensure that the positions of the holes on the sheet metal parts will not shift. However, considering external factors, some holes in the sheet metal parts will slightly shift.

[0003] In the current existing technology, sheet metal hole positioning detection equipment usually adopts a left and right clamping method, so that the sheet metal is clamped and then positioned and detected, thereby ensuring the quality of the sheet metal holes and preventing defective products from entering the market.

[0004] When the existing sheet metal hole positioning detection equipment is in use, it clamps in a single direction, and can only ensure that the sheet metal is clamped in a single direction in the middle part of the device. At this time, the position in another direction will be offset, and then detection errors will occur, affecting the final detection results. Therefore, a sheet metal hole positioning detection equipment is proposed to address the above problems. Utility Model Content
