Working principle: when the stamping die is used, when the upper die of the stamping die completes one stamping action and moves upwards to reset, the front end of the mounting lug is placed in the notch 401 at the moment, then the electromagnet 701 is electrified to operate, so that the driving rack 703 can be driven to move, the driving gear 702 is driven to rotate when the driving rack 703 moves, the pressing block 705 is driven to rotate when the driving gear 702 rotates, and the mounting lug in the notch 401 can be just pressed after the pressing block 705 rotates, so that the mounting lug is fixed; then, the cylinder 608 is started, the cylinder 608 drives the driving rack 609 to move, the driving rack 609 drives the driving gear 606 to rotate when moving, the driving gear 606 drives the vertical rotating shaft 605 to rotate, the vertical rotating shaft 605 drives the outer side positioning cantilever 5 and the first bevel gear 607 to rotate, the first bevel gear 607 drives the second bevel gear 614 to rotate when rotating, the second bevel gear 614 drives the first transmission shaft 610 to rotate and the incomplete gear 612 to rotate, the incomplete gear 612 drives the transmission gear 613 to rotate when rotating, the transmission gear 613 drives the second transmission shaft 611 and the driven gear 603 to rotate, the driven gear 603 drives the horizontal rotating shaft 602 to rotate, the inner side positioning cantilever 4 on the horizontal rotating shaft 602 is driven to rotate, finally, the end part of the inner side positioning cantilever 4 just extends into a station between the two side positioning cantilevers 3, and at the moment, the inner side positioning cantilever 4 just overlaps on one side positioning cantilever 3, the incomplete gear 612 just breaks away from the transmission gear 613, therefore the inner side positioning cantilever 4 is static, the position of a junction box is effectively prevented from exceeding the station, and a connecting claw on a mounting lug on the inner side positioning cantilever 4 just faces a mounting hole on a junction box side wall;
Then the outer side positioning cantilever 5 rotates to the rear side of the junction box and continues to rotate under the action of the air cylinder 608, if the junction box is located at a backward station, the outer side positioning cantilever 5 contacts and pushes the junction box when moving, at the moment, the telescopic push plate 501 at the end part of the outer side positioning cantilever 5 contacts the side wall of the junction box first, the telescopic push plate 501 is utilized to push the junction box first to move, when the junction box contacts the inner side positioning cantilever 4, the junction box and the telescopic push plate 501 cannot move, but the outer side positioning cantilever 5 continues to rotate, the first spring 503 contracts and drives the oblique push plate 803 and the bilateral rack 802 to approach the junction box, at the moment, the two oblique push plates 803 on the outer side positioning cantilever 5 just face the two connecting claws of the mounting lug, the oblique push plate 803 firstly contacts the connecting claws and then presses the connecting claws after moving, so that the two connecting claws bend, then the end part of the rack 802 moves to contact the outer wall of the junction box, so that the bilateral rack 802 and the inserted link 804 move, at the moment, the second spring 805 is compressed and simultaneously drives the two oblique push plates 803 to rotate, at the moment, the two complete connecting claws on the mounting lug are further bent, after the two oblique push plates 803 are connected to the connecting claws, and the junction box is finally fixed on the side wall of the mounting lug and the junction box 803 is fixed on the side wall of the mounting lug;
Finally, by the same way, the electromagnet 701 and the cylinder 608 are started in sequence, so that the inner side positioning cantilever 4 and the outer side positioning cantilever 5 can be reset again, and the subsequent stamping operation and the next positioning operation can be performed;
through setting up outside location cantilever 5, inboard location cantilever 4 and outside cantilever drive assembly 6, can the inside location cantilever 4 of advance drive and outside location cantilever 5 remove in proper order after the cantilever drive assembly 6 operation, inboard location cantilever 4 can avoid the terminal box to surpass the station when removing, outside location cantilever 5 can promote the terminal box that does not reach the station to the station on, and then can make the terminal box accurate stable fall on the station for it is more accurate during the follow-up punching press turn-ups, difficult bad article appears, has improved the production quality of terminal box.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
