The technical scheme is further improved, and a movable connecting rod is arranged between the upper jig and the lower jig; the movable connecting rod is arranged on the opposite surface of the clamp layer.
The technical proposal is further improved, the clamping hand of the movable clamp penetrates through the clamp mounting layer and is movably connected with the double plates; the driving part of the movable clamp is fixedly arranged on the back surface of the clamp mounting layer; the fixture positioning block is arranged on the front surface of the fixture mounting layer. The movable clamp adopts an air cylinder as a driving part.
The technical scheme is further improved, and the fixture mounting layer is provided with a dismounting handle.
The technical scheme is further improved, and the welding jig is arranged in a double-station mode.
The operation steps of the utility model are that firstly, the double-plate is placed on the upper jig and the lower jig, then the position of the positioning block of the jig is adjusted according to the position of the double-plate, the clamping force of the driving part of the movable jig is set according to the strength of plastic, then the upper jig and the lower jig are opposite, and the accurate positioning is realized through the movable connecting rod, and at the moment, the positioning of the upper jig and the lower jig is realized. And finally, the whole jig is accurately connected with an upper die of the welding machine through a locating pin of the upper jig. At this time, the upper die is pressed down, and the lower jig is naturally and accurately positioned on the lower die of the welding machine; further fixing the lower jig; after the fixing is completed, the movable connecting rod between the upper jig and the lower jig is loosened, so that perfect positioning is realized.
The utility model has simple integral structure and convenient operation, and particularly, when different door plates of the card box are required to be manufactured, the installation layer of the welding machine is not required to be replaced; when the clamp installation layer is manufactured, only the clamp positioning block and the movable clamp are required to be adjusted; of course, the clamp positioning block can also be made movable, so that fine adjustment positioning can be realized for the card box door plate with little variation. In addition, a movable connecting rod is arranged between the upper jig and the lower jig; the installation is more convenient, the upper jig and the lower jig are not required to be positioned, and the lower jig is naturally in place. The movable clamp is arranged to be pneumatic, so that clamping force can be set, and damage of the clamp to the door plate of the card box is avoided. The fixture mounting layer is provided with a disassembling handle for convenient carrying.
