Anti-collision device for probe of ultrasonic inspection system

Abstract

The invention discloses an anti-collision device for a probe of an ultrasonic inspection system. An elastic element is sleeved outside the probe; a protective cover is sleeved outside the elastic element; the upper end of the protective cover is connected with one end of a first connecting rod through a hinge; the middle part of the first connecting rod is connected with a fixing bracket through a spherical part; the other end of the first connecting rod is connected with one end of a second spherical connecting rod through a hemispherical part; the other end of the second spherical connecting rod is connected with one end of a reverse L-shaped hemispherical connecting rod; the reverse L-shaped connecting rod is sleeved on the middle of the fixing bracket; meanwhile, the upper end face ofthe reverse L-shaped connecting rod is hung on the inner side face of the fixing bracket through a spring; and the lower end face of the reverse L-shaped connecting rod is connected with an inching switch contact arranged in the fixing bracket. When a foreign body knocks down the protective cover, the protective cover drives the first connecting rod to rotate around a second hinge so as to drive the second connecting rod to deflect for an angle and drive a third connecting rod to move downwards to touch the inching switch to automatically stop a movement system to stop the probe so as to protect the expensive probe from being knocked.

Description

technical field

[0001] The invention relates to a probe anti-collision device, in particular to an anti-collision device for a probe of an ultrasonic flaw detection system. Background technique

[0002] The ultrasonic automatic flaw detection system has a wide range of applications in the industrial field, such as the ultrasonic automatic flaw detection system for turbine shafts, the ultrasonic automatic flaw detection system for aviation parts, etc.

[0003] Under normal circumstances, the probe of the ultrasonic automatic flaw detection system is directly fixed on the moving part, so that when the probe moves under the drive of the moving part, if it accidentally touches a foreign object or a part of the system itself, the probe is easily damaged, and The probe is more expensive, so the loss is larger.

[0004] Therefore, in order to avoid losses, the significance of the ultrasonic automatic flaw detection system probe anti-collision device is particularly important. It ...
