Abstract

The invention discloses a plane difference detection device of concave molded surface holes. The plane difference detection device comprises a checking fixture body, a guide sleeve arranged on the checking fixture body and a detection pin with a guide part inserted in the guide sleeve, wherein a gap pad is installed on one end away from the checking fixture body of the guide sleeve, and a through hole opposite to a center hole of the guide sleeve is formed in the gap pad; the detection pin further comprises a holding part, a detection part and a shaft sleeve axially installed on the detection part in a sliding manner, and at a detection state, the lower surface of the shaft sleeve is jointed with the surface of a workpiece, and a preset gap is reserved between the upper surface of the shaft sleeve and the lower surface of the holding part. In this way, the plane difference detection device of concave molded surface holes is simple in structure, the installation and detection processes of a checking fixture are convenient, and the installation and operation difficulty is reduced; meanwhile, a detection error caused by collision or attrition is avoided, and an accumulated error is reduced to improve the detection precision.

Description

technical field [0001] The invention relates to the technical field of inspection tools, in particular to a detection device for a concave face position and surface difference. Background technique [0002] The precision of automobile body-in-white is an important indicator of the welding process level. High-precision body-in-white can not only improve the assembly quality of assembly parts, but also improve the appearance and clearance quality of the body. At present, in the development process of the whole vehicle, most of the stamping parts are inspected and accepted by inspection tools to confirm whether the precision of the stamping parts is qualified and meets the loading requirements. [0003] Due to the functional requirements of product assembly, some products are provided with holes on the relatively concave surface. When the surface difference of this type of concave surface is directly detected with the detection tool (gap ruler), the detection tool will interfer...
