Anti-collision device of automatic ultrasonic flaw detection system

Abstract

The invention discloses an anti-collision device of an automatic ultrasonic flaw detection system. An elastic element is sleeved outside a probe, and a protection cover is sleeved outside the elastic element. The upper end of the protection cover is connected with one end of a first connecting rod through a first hinge. The middle part of the first connecting rod is connected with one end of a mounting bracket through a second hinge. The other end of the first connecting rod is connected with one end of a second connecting rod through a third hinge. The other end of the second connecting rod is connected with one end of an inverted L-shaped connecting rod through a fourth hinge. The inverted L-shaped connecting rod is sleeved on the middle part of the mounting bracket, and the upper end face of the inverted L-shaped connecting rod is suspended at the inner side face of the mounting bracket through a spring. The lower end face of the inverted L-shaped connecting rod is connected with a micro-switch contact fixed in a fixed mount. When a foreign body hits the protection cover, the protection cover drives the first connecting rod to rotate around the second hinge so as to drive the second connecting rod to deflect a certain angle and drive the third connecting rod to move downwards to touch the micro-switch, then the moving system is stopped automatically so as to stop the movement of the probe to avoid collision of the expensive probe.

Description

technical field [0001] The invention relates to a probe anti-collision device, in particular to a probe anti-collision device for an ultrasonic automatic 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. ...
