A detection tool for output shaft of wiper connecting rod

Abstract

The invention provides a detection tool for a wiper linkage output shaft and belongs to the technical field of vehicle part detection. The detection tool is used for detecting the eligibility of wiper linkage output shafts. The detection tool comprises a base, a sleeve, a floating block and a position-limiting part. A cover plate connected with the base is arranged above the base. A horizontal channel is formed between the base and the cover plate. The base is provided with an installation hole arranged to pass through the base. The aperture of the hole is larger than the outer diameter of the floating block and the hole is perpendicular to the upper surface of the base. The floating block is arranged in the installation hole. The floating block is provided with a peripheral flange that extends towards the channel. The flange is in sliding fit with the channel. The position-limiting part limits the sliding range of the flange. The floating block is provided with a through hole matched with the sleeve. The sleeve is provided with a detection hole configured to axially pass through the bottom surface of the sleeve. The sleeve is also provided with a position-limiting structure used for limiting the downward-sliding extreme position of the sleeve. According to the technical scheme of the invention, the detection tool can be used for comprehensively detecting the angle and the locating information of the wiper linkage output shaft. The detection accuracy is improved. Meanwhile, the quality problem and the scrapped condition of qualified products are avoided.

Description

technical field [0001] The invention relates to the detection field of automobile parts, in particular to a detection tool for the output shaft of a wiper connecting rod. Background technique [0002] The output shaft of the existing integrated wiper linkage mechanism has relatively high requirements on the spatial angle. At present, there are a large number of inspection tools for detecting the spatial angle of the output shaft of the connecting rod mechanism to judge whether the connecting rod mechanism is qualified. For example, the Chinese patent application with the notification number CN202470939U discloses a detection tool for the damper connecting rod of an automobile air conditioner. It includes a base, on which there is a limit hole matched with the connecting column at one end of the damper connecting rod and a limit post matched with the positioning hole of the damper connecting rod; it also includes a guide for detecting the other end of the damper connecting ro...

Problems solved by technology

However, the output shaft of the existing integrated wiper linkage mechanism not only has relatively high requirements on the spatial angle, but also has requirements on the spatial position degree. The tolerance requirements of the position degree and angle cannot be considered at the same time. In order to ensure the quality, the principle of high not low can only be used for control. Only the angle requirement is considered, and the position degree is designed according to the requirement of 0, which will cause this part of qualified products Due to unqualified inspection on the inspection tool and scrap; or due to production errors, according to strict requirements, the pass rate is too low and forced to make certain compromises, there will be quality risks
