Description
Technical Field
The disclosure relates to the technical field of checking tools, in particular to a detection device and detection equipment.
Background
The front end frame is mainly used for fixing functional accessories such as a front end outer decoration of a vehicle body, a radiator, a hood lock bracket and the like, and is in interference fit with the front end frame through deformation of a rivet nut so as to provide internal threads for mounting the functional accessories.
In the prior art, usually, the assembly inspection tool detects the position degree of the rivet nut after the rivet nut is installed on the front end frame (namely, the front end frame assembly). And if the position degree of the rivet nut is unqualified, the front end frame assembly is unqualified. The unqualified front end frame assembly is generally caused by the unqualified position degree of the blind rivet nut mounting hole on the front end frame, and the qualified blind rivet nut mounting hole is the qualified premise of the front end frame assembly, so the position degree qualification rate of the blind rivet nut mounting hole on the front end frame needs to be ensured to improve the product qualification rate of the front end frame assembly.
Because the existing assembly inspection tool is not suitable for detecting the position degree of the blind rivet nut mounting hole, under the condition that the front end frame assembly is unqualified, the position of each blind rivet nut mounting hole on the front end frame assembly is generally dotted by adopting three coordinates, and the front end frame assembly reversely pushes the unqualified part of the front end frame through a three-coordinate report, so that an improved scheme is provided. However, the number of the rivet nut mounting holes on the front frame is large, so that the three-coordinate dotting efficiency is low, and the cost is high. In addition, a single-product checking fixture can be designed independently and used for ensuring the quality of the front-end frame in the initial stage of development. Once the front end frame is qualified in quality and stably produced, the effect of the single-product checking fixture disappears, and the checking fixture is not high in use value, so that the waste of the checking fixture is caused.
