In this embodiment, the pre-assembly comprises at least two sets of the detecting rods 6, including an upper detecting rod 6-1 and a lower detecting rod 6-2, and the height of the fool-proof block 17 is not less than the distance from the rear side edge of the pre-assembly body 4 to the upper detecting rod 6-1. When ensuring that the pre-assembly inserts the fool-proof stop block 17, can all carry out effective detection to two measuring sticks.

The working process and the implementation principle are as follows: the principle explanation is given by taking a group of preassembled components used in the existing production process as an example, and does not represent the uniqueness of specific parameters. The specific parameters can be set according to actual requirements in actual production.

1. Pre-assembling: as shown in fig. 1-2, the pre-assembly has a self-weight of 620G, which creates a gravity G ≈ 6.2N. The spring 2 is made of 65Mn materials, the shear modulus G =79000Mpa, the diameter D =0.4mm of the steel wire, the middle diameter D =4.5mm of the spring 2, the number of effective turns n =7 turns of the spring 2, and the deformation amount f =18-10=8mm.

Elasticity F = F × G × d ^ 4/(8 × N × D ^ 3) =8 × 79000 × 0.4^ 4/(8 × 7 × 4.5^ 3) =3.17N

G is greater than F, the detection rod 6 in the state shown in the figure can not be popped out from the detection rod cavity 18, the flat arrangement of the A surface of the clamp in the assembly process can be ensured, and necessary conditions are provided for the subsequent part arrangement process.

2. Pre-clamping: as shown in fig. 3 to 4, "fixed hinge 10, sliding hinge 12, 2 plastic washers 11, and rivet 25" are installed in this order. The pre-assembled upper cover 1 rotates in the direction of an arrow, and clamping is quickly completed by using the locking magnet 8. A strong magnet with the theoretical suction force of 24N is selected to lock the pre-assembly, the pre-assembly upper cover is easily broken by impact force in the folding process, and the clamp is difficult to open due to the overlarge suction force. The distance between the reserved locking magnet 8 and the preassembled upper cover is 12.4 +/-0.2 mm, the phenomenon that the preassembled upper cover 1 directly impacts the locking magnet 8 can be avoided, the suction force is reduced to 10N after locking, and the effects of quick clamping and opening can be achieved.

After clamping is completed, the clamp is placed on the side for standby, and the surface B is horizontally placed on the workbench.

3. Automatic neglected loading identification: and after the clamp is laterally placed, the B datum is horizontally placed on the workbench. There are four states: a, correctly installing double gaskets; b, the upper gasket is not installed; c, the lower gasket is not installed; d, neither of the double gaskets is installed.

and a state, as shown in fig. 5-8, the elasticity 3.2N of the detection rod 6 is applied to the preassembled upper cover 1 through the plastic washer 11, and if the distance from the left end of the detection rod 6 to the rotating shaft 5 is two times of the distance from the right end of the detection rod 6 to the rotating shaft 5, the preassembled upper cover 1 is subjected to 6.4N of thrust force due to the 2-time force arm relationship, and the thrust force is smaller than the suction force 10N of the locking magnet 8, so that the overall clamp can be ensured to be always maintained in a locked state in the moving process. Meanwhile, the detection rod 6 can not push the plastic washer 11 to be flush with the A reference surface, and can be smoothly placed into the fool-proof stop block 17.

When the remaining three states b, c and d are present, as shown in fig. 9-11, the detecting rod 6 is not blocked by the plastic washer 11, and the right end of the detecting rod 6 moves upwards while the left end protrudes out of the a datum. The upper detection rod 6-1 and the lower detection rod 6-2 only need one protruding A datum and cannot be placed into the foolproof stop block 17. The phenomenon of neglected loading of the plastic ring is found immediately. Only products which are correctly installed and have no neglected loading can be put into a die to realize the final riveting and damping procedures.

Fig. 12 and 13 are a front view and a top view of the present invention mounted on a small table punch. The foolproof stop block 17 is fixed on a sliding plate 21 of a small bench punch, a roller pin is arranged between the sliding plate 21 and a base 20, a hinge and a gasket are well stacked when a pre-assembly is assembled, the hinge and the gasket are conveyed into the rear side of a rivet 25 and placed in the foolproof stop block 17, the sliding plate 21 is pushed to slide to the rear end to abut against the rear stop block, the rivet 25 is respectively aligned with a riveting male die 24 and a riveting lower die 19, finally the upper die moves downwards, and the riveting male die 24, a damping auxiliary male die 23, a damping male die 22 are matched with the riveting lower die 19 to realize punching and riveting.
