A position detection device

Abstract

The invention discloses a position detection device, comprising: a guide rod, one end of which is connected with a handle; a detection sleeve, the detection sleeve includes a groove surface and an end surface, grooves are arranged on the groove surface, and the detection sleeve passes through the groove It is connected with the other end of the guide rod; the bolt passes through the detection sleeve and connects with the guide rod, and the axis of the bolt, the detection sleeve and the guide rod is on the same straight line, the bolt includes a screw rod and a nut, and the nut is located on the end face ; The first steel ball cage is sleeved on the screw rod and is located in the groove. The first steel ball cage is provided with a plurality of steel balls, and the plurality of steel balls are rollingly connected with one end of the guide rod; the second steel ball The retainer is sheathed on the screw rod and is located between the end face and the nut. The second steel ball retainer is provided with a plurality of steel balls, and the plurality of steel balls are rollingly connected with the end face. The invention realizes the detection requirement without the maximum physical position degree, detects the product quickly, and satisfies the detection requirement of mass products.

Description

technical field [0001] The invention belongs to the field of mechanical part detection devices, and in particular relates to a position degree detection device. Background technique [0002] Automobile manufacturing is a system integration project, including tens of thousands of parts. In order to ensure the dimensional quality of the whole vehicle, it is necessary to assign tolerances to each part one by one; as a simple tool for industrial production enterprises to control various sizes of products, inspection tools can Realize rapid detection and accurate judgment of products. In some existing products, due to functional requirements, there is no maximum entity in the position of the measured element at the small mouth end of the product drawing. Because there is no maximum entity, the mouth does not have a fixed effective boundary, so conventional inspection tools cannot be checked. For this position, in the past, products were often tested using professional measuring ...

Problems solved by technology

In some existing products, due to functional requirements, there is no maximum entity in the position of the measured element at the small mouth end of the product drawing. Because there is no maximum entity, the mouth does not have a fixed effective boundary, so conventional inspection tools cannot be checked. For this position, in the past, products were often tested using professional measuring tools, which not only has low detection efficiency and high detection costs, but more importantly, it cannot be applied to mass product inspections.
