Abstract

The invention discloses a detector for a pointer shaft of an automobile instrument, relates to shaft detectors and aims at solving the problems that in traditional detection a pointer shaft is placed in a small optical axis manually, a non-key part is detected by a filler gauge, the size of a key part of the pointer shaft is obtained via theoretical reckoning, and further a detection result is fuzzy and inaccurate and has large error and the detection type is single. The detector comprises a pedestal, a vertical plate, a pointer fixing seat, a linear bearing, a pointer plate, a cylinder, a vacuum pump and two guide posts, the vertical plate is fixedly mounted on the pedestal, the two guide posts are arranged on the pedestal in parallel vertically, the vertical plate over the pointer plate is provided with the cylinder which is arranged vertically, a driving rod of the cylinder penetrates the pointer plate and is fixedly connected with the pointer plate, the tail end of the driving rod of the cylinder is connected with the pointer fixing seat, the pointer fixing seat is provided with a vacuum cavity communicated with an installation groove, and the vacuum pump is communicated with the vacuum cavity of the pointer fixing seat via a negative-pressure air tube. The detector is used for instrument pointer shaft detection.

Description

technical field [0001] The invention relates to a shaft detection device, in particular to a pointer shaft detection device of an automobile meter. Background technique [0002] When the pointer shaft is detected in the traditional way, the pointer shaft is inserted into the small optical axis in the detection hole, so that the pointer stands upright on the detection end surface, and after the detection end surface rises to a certain position, the gap between the end surface and the pointer cap end surface is detected by a feeler gauge. Because the pointer is manually placed on the small optical axis, the direction and strength of the placement are unstable, and the results obtained are not accurate. Moreover, there is no reference object for comparison, and the inspectors cannot detect intuitively. They can only use a feeler gauge to detect non-critical parts, so as to perform theoretical calculations. The results are vague, unclear, and have large errors. There is a singl...
