FIG. 1 is a schematic diagram of the structure of the present utility model;
Fig. 2 is a cross-sectional view of any of the clamping stations of the present utility model.
Detailed Description
The utility model will be described in further detail with reference to specific embodiments and drawings.
The utility model provides a jack welding jig as shown in fig. 1-2, including anchor clamps bottom plate 1, anchor clamps base 2, anchor clamps bottom plate 1 sets up in anchor clamps base 2 top surface, and anchor clamps bottom plate 1 top surface is provided with a plurality of clamping stations along length direction range, and every clamping station is provided with two symmetrical arrangement's supporting seat 3, and the centre of two supporting seats 3 is provided with positioning seat 4, and the top surface of two supporting seats 3 is the inclined plane of opposite direction, and the both sides of supporting seat 3 are provided with stopper 8 for support positioning jack's underarm surface. A pressing mechanism is arranged above the two supporting seats 3 in a right pair.
The positioning seat 4 is provided with a positioning expansion sleeve 5, an expansion core 6 is vertically movably arranged in the positioning expansion sleeve 5, the lower end of the expansion core 6 is connected with a driving device 7, the positioning expansion sleeve 5 is positioned in a through hole on a jack hinge shaft, and the metal sleeve is positioned on the positioning expansion sleeve 5. The lower part of the positioning expansion sleeve 5 is provided with a positioning ring table 51 for supporting the lower end face of the positioning hinge shaft, and the upper part of the positioning expansion sleeve 5 is provided with an expansion surface 52 for expanding the inner circular surface of the metal sleeve. The contact surface of the positioning expansion sleeve 5 and the expansion core 6 is conical, and when the expansion core 6 moves downwards, the positioning expansion sleeve 5 expands outwards, so as to clamp the metal casing.
Further, the driving device 7 is a vertical air cylinder 9 arranged below the positioning seat 4, and the front end of a piston rod of the vertical air cylinder 9 is connected with the lower end of the expansion core 6. The expansion of the metal sleeve is realized by the shrinkage of the cylinder.
