specific Embodiment approach 1

[0012] Specific implementation mode one: combine Figure 1-Figure 5 Explain that a meter pointer shaft detection device in this embodiment includes a base 1, a pointer plate 3, a probe plate 6, a vertical plate 15, a quick clamp 16, a pointer fixing seat 20, two guide columns 9, two An upper linear bearing 8 and two lower linear bearings 4;

[0013] The base 1 is fixed with a vertical plate 15, two guide columns 9 are arranged side by side and installed vertically on the base 1, a lower linear bearing 4 is installed on the lower end of each guide column 9, and the pointer plate 3 is installed on the two lower linear bearings. On the bearing 4, a pointer holder 20 capable of circumferential rotation is installed on the pointer plate 3, the pointer cap of the pointer 21 is installed on the pointer holder 20, and two guide posts 9 above the two lower linear bearings 4 are installed with Two upper linear bearings 8, the probe board 6 is installed on the two upper linear bearings ...

specific Embodiment approach 2

[0018] Specific implementation mode two: combination figure 1 Note that the instrument pointer shaft detection device of this embodiment also includes two positioning pins 5, two positioning pins 5 and two guide columns 9 are arranged side by side, the positioning pins 5 are installed on the base 1, and the positioning pins 5 pass through the pointer plate 3 and the two are in sliding contact. With such arrangement, the positioning pins ensure the parallelism and perpendicularity between the base 1 and the pointer plate 3 and at the same time enable the pointer plate 3 to slide freely up and down. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0019] Specific implementation mode three: combination figure 1 It should be noted that the instrument pointer shaft detection device of this embodiment further includes a plurality of compression springs 19 , and a plurality of compression springs 19 are arranged between the pointer plate 3 and the base 1 and connected to both. The buffer spring provides buffer protection when the pointer shaft 22 is detected. Others are the same as in the first or second embodiment.

Abstract

The invention discloses an instrument pointer shaft detector, 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. The detector comprises a pedestal, a pointer plate, a probe plate, a vertical plate, a rapid clamp, a pointer fixing seat, two guide posts, two upper linear bearings and two lower linear bearings, wherein the vertical plate is fixedly mounted on the pedestal, the lower end of each guide post is provided with one lower linear bearing, the pointer plate is mounted on the two lower linear bearings, the middle of the pointer plate is provided with the pointer fixing seat, the probe plate is mounted on the two upper linear bearings, the middle of the probe plate is provided with the pointer shaft, the vertical plate over the probe plate is provided with the rapid clamp, and the pressure head end of the rapid clamp abuts against the probe plate. 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...
