Abstract

The invention relates to an anti-collision device in the longitudinal direction of an ultrasonic probe. The anti-collision device comprises a bearing bracket, an L-shaped anti-collision baffle, an installation conversion plate, a photoelectric sensor and an elastic screw, wherein the bearing bracket and the installation conversion plate are connected by the elastic screw; the middle of the bearing bracket is provided with the photoelectric sensor; the upper end of the installation conversion plate is provided with the L-shaped anti-collision baffle the vertical part of which is positioned between the signal emitting part and the receiving part of the photoelectric sensor, and under the normal condition, the vertical part of the L-shaped anti-collision baffle cannot block the signal transmitting and receiving; the lower end of the installation conversion plate is connected with the probe. According to the anti-collision device, the ultrasonic probe and a workpiece in the longitudinal direction can be prevented from being collided so as to prevent the probe from being damaged.

Description

technical field [0001] The invention relates to an anti-collision device in the field of ultrasonic detection of electric contact welding quality, in particular to a vertical anti-collision device for an ultrasonic probe. Background technique [0002] In the process of ultrasonic testing the welding quality of electrical contacts, the alignment and focusing of the probe and the contact welding surface are first required, which is completed by moving the probe back and forth, left and right, and up and down. Due to the diversity of workpieces, some workpieces may cause the probe to collide with the workpiece during the vertical movement of the probe, damage the probe, and then affect the use of the entire testing equipment. [0003] In the prior art, such as the invention patent of Chinese Patent Publication No. CN101871915A, this patent provides an anti-collision device for the probe of an ultrasonic flaw detection system, which is covered with an elastic element outside the...
