Detailed Description

The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings:

as shown in fig. 1, people's air defense door shutting connecting rod welding mould, including base platform 2 and the removable 5 groups of stopper units of installing on base platform 2, the stopper unit is including being located jaw stopper 3, connecting rod stopper 4 and go-between stopper 5 on the same straight line, and central authorities are located to go-between

stopper

5, and 5 both sides of go-between stopper are located to two sets of connecting rod stoppers 4 symmetry, and the 4 outsides of connecting rod stopper are located to two sets of jaw stoppers 3 symmetry.

Namely, five groups of locking connecting rods can be welded on the base platform of the clamping fixture in one step, and 3-10 groups of limiting block units can be generally arranged on the base platform according to the arm extension of welding equipment, the conventional size of a welding workbench, the weight of the base platform and the installation convenience.

As shown in the schematic view of the locking link structure shown in fig. 7, it can be seen that the specification of the locking link is mainly determined by the length of the link, and the U-shaped fork and the connecting ring are the same. Therefore, in order to enable the same mould to be suitable for welding processing of locking connecting rods with different length specifications, a plurality of first adjusting holes and second adjusting holes are formed in the base platform, the first adjusting holes are used for positioning the fork head limiting block, two positions are generally arranged on one side of the connecting ring limiting block, and two or three first adjusting holes are arranged at each position (the three first adjusting holes at the extreme end of the diagram are equivalent to two adjusting lengths). The second adjusting hole is used for positioning the connecting rod, three positions are generally arranged on one side of the connecting ring limiting block, it is guaranteed that at least two positions of each connecting rod are limited, and each position is provided with the second adjusting hole.

The structure of jaw stopper is as shown in fig. 4, including threaded connection's screw rod and fastening nut, and every jaw carries out spacing fixed through two jaw stoppers, also can connect two jaw stoppers as an organic whole, makes as shown the go-between stopper similar structure of fig. 5.

The structure of the connecting ring limiting block is shown in fig. 6 and comprises a limiting head and a fastening nut which are in threaded connection, an oval component matched with the appearance of the connecting ring of the locking connecting rod is arranged at the top of the limiting head, and one or two screw rods used for being matched with the fastening nut are arranged at the bottom of the limiting head.
