Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The following describes in detail embodiments of the present invention with reference to the drawings. In the drawings, the same reference numerals indicate the same or corresponding features. The figures are only schematic and are not necessarily drawn to scale.
Referring to fig. 1, 2 and 3, the multi-layer composite wear-resistant scraper middle groove as shown comprises: the clamping jaw base 1, the telescopic structure 9, the displacement sensor 10, the loudspeaker module 11 and the strong spring 5, wherein the telescopic structure 9 comprises a positioning block 2, a telescopic block 3 and a contact block 4, the positioning block 2 is fixedly connected with the telescopic block 3 and the contact block 4 in sequence in a welding manner, the positioning block 2 is slidably arranged in a sliding long groove 8 in the clamping jaw base 1, the telescopic block 3 is positioned in a telescopic hole 6 formed in the end part of the clamping jaw base 1 in the direction close to the workpiece, the telescopic block 3 can freely slide in the telescopic hole 6, the strong spring 5 is arranged in an inner space of the sliding long groove 8 formed by the sliding long groove 8 and the positioning block 2 and far away from the workpiece, a communication hole 7 is formed in the top of one end of the clamping jaw base 1 far away from the workpiece, the diameter of the communication hole 7 is smaller than that of the strong spring 5, the displacement sensor 10 and the loudspeaker module 11 are fixedly connected to the top end of the clamping jaw base 1 in a gluing manner, and a probe of the displacement sensor 10 passes through the communication hole 7, the probe of the displacement sensor 10 is positioned in the middle through hole of the strong spring 5, the end part of the probe of the displacement sensor 10 is contacted with the top end of the positioning block 2, and the speaker module 11 for alarming is electrically connected with the displacement sensor 10.
