Gauge for left front door step plate of automobile

Abstract

The invention discloses a gauge for a left front door step plate of an automobile. The gauge for the left front door step plate of the automobile is composed of a base (1), a stand column (2), four pairs of rapid callipers (3), a locking bolt (4), a profile gap go-no go fixed gauge (5), a left front door step plate gauge datum plane insert (6), a left front door step plate gauge main positioning block (7), a left front door step plate gauge auxiliary positioning block (8), a left front door step plate gauge profile positioning insert (9) and left front door step plate gauge lifting lugs (10). The gauge for the left front door step plate of the automobile is characterized in that the left front door step plate gauge profile positioning insert (9) is fixed to the stand column (2) through the locking bolt (4), the four pairs of rapid callipers (3) are installed on the periphery of the left front door step plate gauge profile positioning insert (9), and the profile gap go-no go fixed gauge (5) is used for detecting the profile tolerance of the profile of a workpiece. The gauge for the left front door step plate of the automobile is simple in structure, convenient to transport, capable of conducting measurement evaluation on the relevant size relation of the detected workpiece rapidly, guaranteeing the consistency of product production, and improving the product assembly efficiency.

Description

technical field [0001] The invention relates to the technical field of detection of automobile parts, in particular to a detection tool for detecting steps on the left front door of an automobile. Background technique [0002] The left front door step of a large car is made of FRP. Although FRP has a mold to ensure the basic product size in the production process, the left front door step is not only an appearance part, but also a stressed part. Therefore, when installing, special In order to ensure the installation size, the surface detection pin is required to detect the edge of the part. In the past, the metal frame type point contact tool was used for detection, but the metal detection part tool rubbed against the workpiece during the detection process, which caused the wear of the measurement surface and made the detection occur. Deviation, and during detection, the inspector holds the detection pin and inserts it into the hole for detection, and then pulls out the dete...

Therefore, when installing, special In order to ensure the installation size, the surface detection pin is required to detect the edge of the part. In the past, the metal frame type point contact tool was used for detection, but the metal detection part tool rubbed against the workpiece during the detection process, which caused the wear of the measurement surface and made the detection occur. Deviation, and the inspector holds the detection pin and inserts it into the hole for detection, and then pulls out the detection pin after completion, which brings trouble to the detection work, makes the detection work inefficient, and cannot be quickly and accurately detected
