In addition, in order to obviously promote the clamping effect of clamping assembly 7, the quantity of clamping assembly 7 corresponds to the quantity of a row of rivet holes 101 that side board 13 is closest to curb plate 2 to be set up, and a plurality of pulling rods 73 are all enclosed by blast pipe 81, and the one end that pulling rod 73 kept away from buckling parts 722 is fixedly connected with limiting block 731, limiting block 731 butt in fixed plate 82 are facing away from limiting plate 71's one side, and fixed plate 82 is provided with handle 821 facing away from limiting plate 71's one side to the staff pulls fixed plate 82 conveniently.
The application mode of the positioning tool of embodiment 2 is as follows: after a worker clamps the edge of the side plate 13 and the side plate 2 in the clamping groove 61, the plurality of buckling parts 722 can be just abutted against the inner concave surface of the expansion riveting hole 101 to play a limiting role, and then the worker can finish the pull riveting work through the operation hole 62; when the positioning tool needs to be removed, a worker pulls the handle 821, and in the process that the fixing plate 82 is far away from the limiting plate 71, the fixing plate 82 is abutted against the limiting block 731, so that the limiting block 731 pulls the buckling part 722 to shrink, and the positioning tool can be removed; and the worker pulls the handle 821 so that the fixing plate 82 presses the blower tube 81, and the air flow of the blower tube 81 can be blown out from the movable hole 711 and purge the wall of the clamping groove 61, reducing the chips adhered to the wall of the clamping groove 61.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
