Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-7: an adjustable sleeve molding device of a spot welding machine comprises a fixing plate 1, a middle inner die 2, a left inner die 3, a right inner die 3 and an elastic adjusting structure. The middle part centre form fix on fixed plate 1, middle part centre form 2 opens there is the opening, elasticity adjust the structure and arrange in the opening of middle part centre form 2, and be connected with fixed plate 1, elasticity adjust the upper and lower both sides of structure and the face of middle part centre form 2 opening and contact, elasticity adjust the left and right sides of structure respectively with control the medial surface of centre form 3 and contact, fixed plate 1 open and have the notch, control centre form 3 all with the notch sliding connection of fixed plate 1, and be connected with the both ends about middle part centre form 2 respectively. Elasticity adjust the structure and include regulating block, spring 5 and locking bolt 6, the regulating block be trapezoidal regulating block 4, trapezoidal regulating block 4 the left and right sides respectively with control centre form 3 contacts, upper and lower both sides and the contact of centre form 2 in the middle part, open at trapezoidal regulating block 4's middle part has the hole, spring 5 pass the hole and with trapezoidal regulating block 4 fixed connection, spring 5's one end and the connection of centre form 2 in the middle part, locking bolt 6 pass spring 5 and be connected with fixed plate 1, locking bolt 6 be used for restricting trapezoidal regulating block 4's position. The inner die is characterized by further comprising a locking block 12, a fixing bolt 7 and a shaft shoulder bolt 13, wherein the locking block 12 is in sliding connection with the fixing plate 1, the left inner die and the right inner die 3 are fixed on the locking block 12 through the fixing bolt 7, the shaft shoulder bolt 13 penetrates through the left inner die and the right inner die 3 to be connected with the middle inner die 2, and the left inner die and the right inner die 3 are in sliding connection with the shaft shoulder bolt 13. The upper side and the lower side of the middle inner die 2 are provided with notches, the middle inner die further comprises a material pushing device arranged behind the adjustable sleeve molding device, the material pushing device comprises a material pushing cylinder 8, a guide rod mounting plate 9, a guide rod 10 and a push plate 11, the guide rod mounting plate 9 is connected with a cylinder shaft of the material pushing cylinder 8, one end of the guide rod 10 is connected with the guide rod mounting plate 9, the other end of the guide rod is connected with the push plate 11, and the push plate 11 penetrates through the notches of the middle inner die 2. The welding process of sheet generally is by the lower mould of spot welder edge rolling mechanism rise to press the sheet on the sleeve moulds the type device, with the preliminary crooked edge rolling of sheet, the clamping mechanism of machine both sides presss from both sides the crooked both ends of sheet respectively again, spot welding work carries out at last again, edge rolling mechanism and clamping mechanism all belong to prior art, do not do any longer, when the lower mould of edge rolling mechanism rises and presses the sheet both ends centre form 3 about, centre form 3 can move to the direction of centre form 2 through shoulder bolt 13 smooth surface and locking piece 12 about, promote trapezoidal regulating block 4 and spring 5 and outwards stretch, make the lower mould can with about centre form 3 laminating, thereby process out the sleeve, when the sleeve of different diameters need be processed, only need to roll up the lower mould of circle mechanism adjust can, adjustable sleeve moulds the type device and can adjust automatically when the lower mould is pushed down to rise.

The normal welding process of the sheet material is that a lower die of a rolling mechanism of a spot welding machine is lifted to press the sheet material on a sleeve molding device, the sheet material is preliminarily bent and rolled, two bent ends of the sheet material are respectively clamped by clamping mechanisms on two sides of the machine, and finally spot welding is carried out. When the lower die of the rolling structure is lifted to press the sheet material on the left inner die and the right inner die of the utility model, the left inner die and the right inner die can move towards the direction of the middle inner die (the rolling mechanism belongs to the prior art and is not repeated), because the left inner die and the right inner die are respectively contacted with the left side surface and the right side surface of the trapezoidal adjusting block, the trapezoidal adjusting block can be gradually pushed outwards (the spring is in a stretching state because the trapezoidal adjusting block is fixedly connected with the spring), the lower die can be ensured to be jointed with the left inner die and the right inner die, thereby sleeves with required diameters can be processed (the sleeves with different diameters are only required to be adjusted on the lower die of a machine, the sleeve molding device can automatically adjust the diameter of the processed sleeve according to the shape of the lower die), after the welding work is completed, the lower die of the rolling structure of the machine returns to the position, the spring returns, the trapezoidal adjusting block is pulled to move inwards, after all devices reset, the pushing cylinder moves to drive the push plate to slide on the notch of the middle inner die, and the welded sleeve is pushed out (due to the fact that the sheet is made of elastic sheets, if the rounding condition occurs in the clamping process, the round rolling mechanism can automatically reset to be a round sleeve after resetting).

The elastic adjustment structure principle is as follows: when the left inner die and the right inner die are pressed by the lower die to move towards the direction of the middle inner die, the position of the trapezoidal adjusting block is pushed to gradually move towards the outer side of the middle inner die, and meanwhile, the spring is stretched to ensure that the left inner die and the right inner die can be tightly attached to the lower die; when the lower die returns to the original position, the spring resets, and the left inner die and the right inner die are pushed to reset by the trapezoidal adjusting block.
