Abstract

The invention discloses a device for measuring the part concealed portion gap value. The device comprises a handheld base, an end cover, a fixed measuring needle, a movable measuring needle, a radial poking rod, a sliding wedge, a longitudinal push rod and a reading device; the handheld base is internally of a hollow structure, the end cover is installed at one end of the handheld base, a fixed measuring needle base and a movable measuring needle base are arranged on the upper portion of the end cover, the fixed measuring needle is arranged on the fixed measuring needle base, the movable measuring needle is arranged on the movable measuring needle base, and the movable measuring needle base penetrates through a transverse sliding groove formed in the and abuts against the inclined face at one end of the sliding wedge located in the handheld base; the radial poking rod penetrates through the handheld base and the movable measuring needle base on the lower portion of the end cover in the radial direction; the reading device is arranged in the other end of the handheld base, and the longitudinal push rod is arranged between the other end of the sliding wedge and the reading device. By adopting the fixed measuring needle, the movable measuring needle and the longitudinal push rod moving in the axial direction, the data obtained through transverse measurement is converted into axial data to be displayed, and then the part gap value is measured.

Description

technical field [0001] The invention relates to the technical field of auto parts measurement, in particular to a device for measuring the gap value of hidden parts of the parts when the automobile sheet metal parts, interior parts and long waist holes are in hidden positions. Background technique [0002] At present, while the rapid development of the automobile industry is promoting the prosperity of the manufacturing industry, it also has higher and higher requirements for the matching quality and dimensional accuracy of the whole vehicle, especially for the dimensional control of the assembly or a single product. . The dimensional inspection method has gradually moved from product sampling inspection to full inspection, and requires the realization of automatic data collection, monitoring, analysis and traceability control requirements. This is not only a requirement of OEMs, but also various parts factories have taken action to respond to the demand for future parts co...
