Description
Technical Field

Background
As shown in fig. 1, the magnetoelectric velocity sensor 1 includes 4 sections of iron cores 10, the head of the 4 sections of iron cores have short arcs 11, 12, 13, 14 respectively, and make up the virtual curved surface 15 tested, in the actual use of the magnetoelectric velocity sensor, the speed measuring gear is a magnetic field induction component nested on the wheel axle, rotate with the wheel synchronously, the magnetoelectric velocity sensor is mounted on the side of the speed measuring gear, the virtual curved surface 15 of its front end keeps certain interval with the top surface of the speed measuring gear, when the wheel rotates, the speed measuring gear cuts the magnetic field, the sensor transmits the pulse signal, can reflect the train running speed accurately according to the pulse signal; therefore, the gap detection is an indispensable link in the production of the magnetoelectric speed sensor, the performance and the quality of the magnetoelectric speed sensor are determined by the accuracy of the gap detection, the manufacturing efficiency of a product is determined by the fast and slow detection time, and the device for automatically detecting the gap of the magnetoelectric speed sensor has decisive influence on the performance, the quality and the yield of the product.
As shown in fig. 2 and 3, the gap detection of the conventional magnetoelectric speed sensor adopts an indirect measurement mode and is operated by hands. Firstly, the soldering tin wire 4 is fixed on the virtual curved surface 15 of the magnetoelectric speed sensor product, the soldering tin wire is gradually pressed and deformed in the process of approaching the curved surface of the product to the fixed curved surface of the measuring tool 5, and finally, the gap value is indirectly obtained by detecting the thickness of the soldering tin wire 4. In order to measure the distance of the whole core segment, the upper and lower two solder wires 4 are used for measurement. The detection method has the following defects:
1) the testing efficiency is low, the soldering tin wires are required to be manually fixed on the curved surfaces of the products formed by the 4 sections of iron cores 10, then the products are held by hands, the moving process of the movable curved surfaces is realized through the tool 5, and finally the deformation quantity of the soldering tin wires is manually detected and recorded one by one.
2) The reliability of data is not high, the solder wire rebounds to a certain degree after being pressed, and data tracking is difficult to perform through manual recording; the measurement result can not reflect the real clearance easily, and the product quality judgment is influenced.
3) The requirement on the skills of testers is high, interpersonal difference exists in the manual work reading deformation, the solder wire material is softer, and the dynamics size is the most core factor that influences the measurement accuracy in the slide caliper rule measurement process, consequently, the skill requirement on the testers measurement is very high.
4) The sensor core 10 is subject to a force and is easily damaged.
