Bushing press-fitting height and necking gap automatic detection device

Abstract

The invention provides a bushing press-fitting height and necking gap automatic detection device, and belongs to the technical field of detection devices. The device comprises a supporting mechanism, a height detection mechanism, a bushing press-fitting mechanism, a workpiece positioning mechanism and a necking detection mechanism, wherein the height detection mechanism, the bushing press-fitting mechanism, the workpiece positioning mechanism and the necking detection mechanism are arranged on the supporting mechanism. The height detection mechanism comprises an upper plate arranged on the supporting mechanism, a servo electric cylinder arranged on the upper portion of the upper plate, a guide rail horizontally arranged on the lower portion of the upper plate, a first air cylinder connected with the guide rail and a displacement sensor arranged on the guide rail. The necking detection mechanism comprises a support, a second air cylinder, an industrial camera and a third air cylinder, wherein the support and the second air cylinder are arranged on the supporting mechanism, the industrial camera and the third air cylinder are arranged on the support, and the industrial camera is connected with a controller. According to the device, whether the exposed height and the necking gap generated after bushing press fitting meet the tolerance requirement or not can be rapidly and accurately detected, use is convenient and rapid, stability is good, and accuracy is high.

Description

Technical field[0001]The present invention belongs to the technical field of detecting device, and in particular, a device for automatic detection of a liner pressure (automatic detection).Background technique[0002]The existing bushing exposed height is to use the touch rules after the pressing process is completed, it is qualified, which cannot be effectively defeated before the start of the process, causing production waste; the existing liner is compressed, the plug gap is 0.25mAX, the size of the size is 0.25mm plug Detection Determine if it is qualified, not passing it, passing to fail. The artificial testing section is long, and there is also a large miscrosis risk.[0003]CN 208887536 U disclose a multifunctional bushing, including a bottom plate, an inner diameter jeweler, an outer diameter knife and a high degree of inspection, including a base, a base, fixed to the bottom plate, and fixed there is a base. The inner diameter stopping, the top of the inner diameter stopped reg...

AI Technical Summary

Problems solved by technology

[0002] The exposed height of the existing bushing is judged by the touch gauge after the press-fitting process is completed, which cannot effectively prevent mistakes before the process starts, resulting in waste of production; the existing bushing shrinkage clearance is 0.25max, and the size specification is The 0.25mm feeler gauge is tested for one week to determine whether it is qualified, if it fails, it is qualified, and if it passes, it is unqualified

Manual detection takes a long time, and there is also a greater risk of misjudgment
