Symbol description in the drawings:
1. the welding fixture comprises a lower positioning column, a connecting rod, an upper positioning column, a supporting plate, a hexagonal flat round head screw, a 6.U handle, a welding surface body, a flange and a flange.
Detailed Description
The utility model will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the hand-held flange welding bolt hole coaxiality detection device comprises a support plate 4,U type handle 6 fixedly connected with the upper end surface of a support plate 4; the upper end of the connecting rod 2 is inserted into an inner hole of the supporting plate 4 (in transition fit), and is fixedly connected with the upper end of the supporting plate 4 through a hexagon flat round head screw 5, and the connecting rod 2 is inserted into the inner hole of the supporting plate 4 to be convenient to detach; the upper positioning column 3 is sleeved on the upper portion of the connecting rod 2 and fixedly connected in an interference fit mode, a conical chamfer is arranged at the lower end of the upper positioning column 3, and the upper end face of the upper positioning column 3 is flush with the lower end face of the supporting plate 4. The lower locating column 1 cover carries out fixed connection at the lower extreme of connecting rod 2 with interference fit's mode, and the lower terminal surface of lower locating column 1 flushes with the lower terminal surface of connecting rod 2, and the upper end, the lower extreme of lower locating column 1 all are equipped with the toper chamfer. The figure shows that the number of the connecting rods 2 is eight, and the eight connecting rods 2 are uniformly distributed along the circumferential direction; it should be noted that, the number of the connecting rods 2 can be adjusted according to actual conditions, the remaining connecting rods can be used as spare parts for subsequent use, and the positions of the connecting rods are uniformly distributed along the circumferential direction during design. The number and the positions of the flange connecting rods with different diameters are different.
As shown in FIG. 2, the two ends of the welding gauge body 7 are provided with the flange 7-1 and the flange 7-2, when the hand-held flange welding bolt hole coaxiality detection device is used, a worker holds the U-shaped handle 6, respectively passes eight lower positioning columns 1 through 8 bolt holes on the flange 7-2, then downwards continuously inserts the eight lower positioning columns 1 into the 8 bolt holes on the flange 7-1 respectively, simultaneously inserts the upper positioning column 3 into the 8 bolt holes on the flange 7-2, and the lower end face of the supporting plate 4 is tightly attached to the end face of the flange 7-2. The upper positioning column 3 is positioned in the bolt hole of the flange 7-2, and the lower positioning column 1 is positioned in the bolt hole of the flange 7-1, so that coaxiality of the corresponding two bolt holes is qualified. If the upper positioning column 3 is positioned in the bolt hole of the flange 7-2 and the lower positioning column 1 is not positioned in the bolt hole of the flange 7-1, the coaxiality of the corresponding two bolt holes is judged to be unqualified.
After the detection is finished, the handheld flange welding bolt hole coaxiality detection device is slowly pulled out, so that collision is avoided.
