Efficient bolt detection device

Abstract

The invention provides an efficient bolt detection device which is used for detecting the reactive force of an automobile bolt and comprises a bolt screwing-in mechanism, an up-down displacement mechanism, a nut fixing oblique angle mechanism, a reactive force balance weight mechanism and a tightening mechanism. The nut fixing oblique angle mechanism comprises two supporting vertical plates, a rotating cavity, a nut fixing block, a nut pressing block, an oblique angle adjusting bolt, a fixing bottom plate, a fixing shaft and two first rolling bearings. The two supporting vertical plates are separately arranged on the two sides of the fixing bottom plate, the rotating cavity is arranged between the two supporting vertical plates in a deflectable mode through the fixing shaft, and the firstrolling bearing is connected with the fixing shaft in a sleeving mode, the nut fixing block is arranged on the rotating cavity, the nut pressing block is connected with the rotating cavity through a bolt in a locking mode, and the nut pressing block is arranged above the nut fixing block, and one end of the oblique angle adjusting bolt is connected with the rotating cavity. Accurate measurement ofthe reactive force of the bolt is realized.

Description

technical field [0001] The invention relates to a detection device, in particular to an efficient detection device for the reaction force of automobile bolts. Background technique [0002] With the development of science and technology, technological progress and innovation, automobile products are changing with each passing day, and higher technical requirements are also put forward for stamping parts and fastener products. Automobile fasteners are an important field for my country's automobile industry to participate in globalization. [0003] In the manufacturing industry, fasteners are widely used, especially as an important part of automobiles. The stability of their shape and size directly determines the accuracy of the body and the comprehensive elements of the vehicle. In the production process, the fasteners must be inspected and the inspection results are compared with the judgment standard to determine whether each fastener product or each batch of fasteners is qu...

AI Technical Summary

Problems solved by technology

[0004] At present, fasteners generally use special inspection fixtures as the main detection method to control the quality of fasteners. In terms of reaction force detection, inspectors use electric screwdrivers, bogies, tightening machines and other tools to tighten manually. As a result, the detection data is greatly deviated by human factors, resulting in inaccurate data, so it cannot directly reflect the status of fasteners, thereby reducing the detection efficiency and the accuracy of product detection data

[0005] Therefore, the reaction force detection device of the fastener in the prior art still has a place to improve
