Inspection tool structure for guide track of rear door

Abstract

The invention provides an inspection tool structure for a guide track of a rear door. By means of the inspection tool structure, the inspection process of an inner plate of a left girder of an automobile is simple, the period is short, the efficiency is high, and the accuracy is high. The inspection tool structure comprises a bottom plate, and datum sleeves are arranged in the positions of three corners of the bottom plate respectively; a simulation block is located on the upper end surface of the bottom plate; an external bulged structure is arranged on one side of the simulation block; a positioning plane is arranged on the inside perpendicular plane of the external bulged structure; the external bulged thickness of the positioning plane is 3 mm; an upward bulged front positioning block and an upward bulged rear positioning block are arranged on the upper end surface of the other side of the front and the rear of the simulation block; a middle positioning block is arranged between the front positioning block and the rear positioning block and corresponds to a middle slot in the guide track of the rear door; and the upward bulged heights of the front positioning block, the rear positioning block and the middle positioning block are 3 mm.

Description

technical field [0001] The invention relates to the technical field of the inspection fixture structure of auto parts, in particular to a inspection fixture structure of a rear door guide rail. Background technique [0002] Existing detection of the rear door guide rail of the car, which uses the inspection tool to detect the data of each part separately, and then compares it with the standard value to determine whether the rear door guide rail is qualified. Due to the measurement error during the comparison process, the detection data obtained by the inspection tool is still low. Minor trimming is required, the detection process is complex, the cycle is long, the efficiency is low, and the error is large. Contents of the invention [0003] In view of the above problems, the present invention provides a detection device structure for the guide rail of the rear door, which makes the detection process of the inner panel of the left longitudinal beam of the automobile sim...
