Abstract
The utility model relates to an overall dimensions inspection tool for automobile parts, and specifically, discloses a displacement inspection tool for a pivot of a crank of a windscreen wiper. The displacement inspection tool comprises a base plate, the rear part of the base plate is fixedly provided with a transverse pivot locating groove and a pivot hold-down mechanism; the size of the pivot locating groove is matched with the diameter of the pivot of the windscreen wiper assembly, and the pivot hold-down mechanism can hold the pivot down in the pivot locating groove without limiting the rotation of the pivot; the middle part of the base plate is provided with a longitudinal guide rail and a sliding base capable of moving longitudinally along the guide rail; the sliding base is provided with a transverse pin shaft locating groove and a pin shaft hold-down mechanism, the size of the pin shaft locating groove is matched with the diameter of a pin shaft of the windscreen wiper assembly, and the pin shaft hold-down mechanism can hold the pin shaft down in the pin shaft locating groove; and the front part of the base plate is provided with an inspection apparatus capable of inspecting the longitudinal displacement distance of the sliding base. By the displacement inspection tool, the defect of low inspection efficiency of the existing CMM (Coordinate Measuring Machine) is solved, the product inspection efficiency is improved effectively, the product quality can be controlled effectively, and the quality cost is lowered.
Description
Technical field
The utility model relates to the overall size instruments of inspection of auto parts, specifically a kind of windscreen wiper crank pivot position detecting tool that is used for checking the pivot location degree size of vehicle wiper driving crank.
Background technology
The windscreen wiper crank assemblies is to be used for the parts of outputting power in vehicle wiper, its structure as shown in Figure 1, generally include a crank and the pivot and the bearing pin that are positioned at the crank two ends, its pivot is connected by welding and the mounting hole of crank end usually, therefore needs to detect the depth of parallelism at pivot center and bearing pin center and the right alignment of pivot and crank end mounting hole.When using at present the CMM method to carry out the detection of windscreen wiping system for automobile pivot shaft, need about 5 minutes, the efficient of detection is very low.Because the restricted production run that CMM detects can only 1-2 hour censorship once, have so very large quality risk.Improved simultaneously corresponding quality cost, production efficiency also has certain impact.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of position degree that can fast detecting windscreen wiper crank pivot is provided, and windscreen wiper crank pivot position detecting tool simple in structure, easy to operate, that cost is low.
Windscreen wiper crank pivot position detecting tool of the present utility model includes a base plate, and the base plate rear portion is fixedly installed a horizontal pivot locating slot and a pivot pressure holding mechanism; The size of described pivot locating slot matches with the pivot diameter of windscreen wiper crank assemblies, described pivot pressure holding mechanism can be with the pivot pressure holding in the pivot locating slot and do not limit the pivot rotation; Base plate middle part is provided with guide rail and one slide that can vertically move along guide rail longitudinally; Be provided with a horizontal bearing pin locating slot and a bearing pin pressure holding mechanism on slide, the size of bearing pin locating slot matches with the pin diameter of windscreen wiper crank assemblies, and bearing pin pressure holding mechanism can be with the bearing pin pressure holding in the bearing pin locating slot; Described base plate front portion is provided with a pick-up unit that can detect slide length travel distance.
Described pick-up unit is a dial gauge.
The utility model has overcome the low defective of existing CMM detection efficiency, can adopt master body to cubing school zero, and by with master body to recently judging the whether qualified of product, thereby effectively raise the efficient that product detects, and can effectively control the quality of product, reduce quality cost.

Fig. 2 is the status architecture schematic diagram of the utility model embodiment before workpiece is not also detected by pressure holding;
Fig. 3 is the status architecture schematic diagram of the utility model embodiment when detecting.
Embodiment
As shown in Figure 2 and Figure 3, this windscreen wiper crank pivot position detecting tool includes a base plate 1, and the base plate rear portion is fixedly installed a horizontal pivot locating slot 2 and a pivot pressure holding mechanism 3; The size of pivot locating slot 2 matches with the pivot G1 diameter of windscreen wiper crank assemblies G, pivot pressure holding mechanism 3 can be with pivot G1 pressure holding in the pivot locating slot and do not limit the pivot rotation; Base plate 1 middle part is provided with guide rail 4 and one slide 5 that can vertically move along guide rail longitudinally; Be provided with a horizontal bearing pin locating slot 6 and a bearing pin pressure holding mechanism 7 on slide, the size of bearing pin locating slot 6 matches with the bearing pin G2 diameter of windscreen wiper crank assemblies G, and bearing pin pressure holding mechanism 7 can be with bearing pin G2 pressure holding in the bearing pin locating slot; Base plate 1 front portion is provided with a pick-up unit 8 that can detect slide length travel distance.This pick-up unit is a dial gauge.
The detection of the utility model embodiment is crossed and is, first with the pivotally placed of workpiece for measurement in pivot G1 locating slot 2 and pressure holding, then rotary crank G3, make bearing pin G2 enter bearing pin locating slot 6, by bearing pin pressure holding mechanism 7 pressure holding bearing pins, due to bearing pin locating slot 6 matching relationship with bearing pin, at the effect lower slider 5 of press force, length travel to bearing pin locating slot 6 is coordinated fully with bearing pin G2, the reading by dial gauge can judge whether workpiece is qualified at this moment.
