Automatic screening instrument for automobile engine blank caps

Abstract

The invention relates to an automatic screening instrument for automobile engine blank caps. The automatic screening instrument is used for automatically screening the blank caps meeting the diameter dimension requirements. The automatic screening instrument comprises a centrifugal vibration hopper, a guide rail and a detection table. A detection mechanism and a controller are arranged on the table surface of the detection table. The detection mechanism comprises an air cylinder, a first fixed check block and a second fixed check block. The first fixed check block and the second fixed check block are arranged oppositely to form a V-shaped detection groove. A pair of detection blocks is oppositely arranged on the inner side walls of the detection groove. The detection blocks are provided with a contact sensor connected with the controller. One end of the guide rail is connected with the centrifugal vibration hopper, and the other end of the guide rail is arranged at an inlet of the detection groove. The top of the detection air cylinder is opposite to the inlet of the detection groove. Compared with the prior art, the automatic screening instrument has the advantages that automatic detection and appearance detection are achieved, and detection is accurate.

Description

technical field [0001] The invention relates to the field of product detection, in particular to an automatic screening instrument for stuffy covers of automobile engines. Background technique [0002] Automobile engine stuffy cover is assembled on the engine block and plays the role of sealing engine oil. The main sealing position of the part is the outer diameter of the part. The existing detection method adopts the no-go ring gauge 100 % inspection to ensure product quality. [0003] However, the use of go-no-go ring gauges to detect parts requires manual inspection. Not only is the cost of personnel high, but also whether the outer diameter of the part is intact is mostly controlled by personnel, which not only costs a lot of manpower and material resources, but also requires personnel to ensure product quality. Such measure is also a kind of temporary measure, and the parts must be guaranteed to be 100% qualified as safety parts, and no mistakes can occur, otherwise a ...

[0003] However, the use of go-no-go ring gauges to detect parts requires manual inspection. Not only is the cost of personnel high, but also whether the outer diameter of the part is intact is mostly controlled by personnel, which not only costs a lot of manpower and material resources, but also requires personnel to ensure product quality. Such a measure is also a temporary measure, and the parts are safety parts that must be guaranteed to be 100% qualified, and there must be no mistakes, otherwise a mistake will affect the safety of the car and personnel, and the consequences will be very serious
