Description

Technical Field

[0001] The utility model relates to the field of position gauge repair tools, in particular to a position gauge repair tool for round holes of automobile frame parts. Background Art

[0002] During the mass production of automotive sheet metal parts, a gauge is needed to detect whether the holes on the parts are qualified. Existing gauges for hole detection of porous products usually use spring detection pins for manual detection, but after long-term use and wear, the connection point between the pin head and the pin seat is prone to loosening and cracking, causing the pin head to shift or even fall off, and the detection cannot be completed smoothly. In order to reduce the cost of replacement, it is usually repaired, but the detection pin will retract into the gauge platform when not in the detection state. It is difficult to always position the pin head at the center point of the pin hole during maintenance. Therefore, we designed a repair tool for the circular hole position gauge of automotive frame parts. Utility Model Content
