Fig. 7 is a schematic diagram of the automatic placement of the forceps body 80 of fig. 3 on a rail according to the present invention. In fig. 6-7, when the pincer body 80, either in d1 or d2 form, moves to the two cylindrical adjustment rails 226, under the gravity action of the gravity center concentration at the grinding disc of the pincer head, it will turn over as in fig. 6-7, forming a uniform arrangement form, i.e. achieving the purpose of automatic sequencing of the present invention, thus saving labor, and being efficient and convenient.

This occurs during the self-alignment of the pincer body 80 as it falls from the feed magazine 21 onto the alignment rail 226. Therefore, the sequencing and positioning of the pliers are conveniently realized.

Preferably, the tail end of each push plate of the pushing assembly is connected with two groups of push rods: a first pushrod 403 and a second pushrod 402; and the first push rod 403 is movably fixed at the front end of the second push rod 401. When the material is pushed, the second push rod 402 is pushed forwards firstly, and after the machining operation is finished, the first push rod 403 pushes the material forwards to fall; after the second stage of pushing is completed, the two push rods are retracted together. Of course, in actual use, the push rod can be designed to be one push rod and two strokes.

Preferably, the front end of each push plate of the pushing assembly is provided with an arc structure which is correspondingly matched with the pliers body. Adopt the appearance matching of arc shape structure and pincers body 80, avoid taking place to deflect and squint at the in-process of propelling movement, the accurate processing production of being convenient for.

Preferably, each processing layer on the discharging assembly comprises a first processing layer 222, a second processing layer 223 and a third processing layer 224; the corresponding push plates are respectively a second push plate 412, a third push plate 413 and a fourth push plate 414. In the actual production and processing process, a drilling machine for processing production can be additionally arranged above each processing layer; and the first push plate 411 is located above the adjustment rail 226 on the material pushing layer 221.

Preferably, the right side of the movable partition 216 is fixedly disposed above the material pushing layer 221 through a partition bracket 217.

Preferably, the left side of the adjustment rail 226 is configured as a slope, and the angle between the slope and the horizontal plane is 30-70 °.

In specific use, referring to fig. 3-5, the pincer body 80 to be processed is directly stacked in the spiral surrounding type feed tray 101, and after the system is started, the loaded pincer body 80 is continuously conveyed to the feed chute 104 in a head-forward manner under the action of the vibration table 110, and is sensed by the discharge detector 213 at the tail end of the feed chute 104.

After the material to be processed enters the feeding bin 21, because the feeding bin 21 adopts a combined inclined plane feeding bin 21 structure, the pincer body 80 slides into the feeding bin 21 after being sent out from the feeding groove 104, at the moment, the push plate moves forwards, the movable partition plate 216 just catches the bottom of the U-shaped feeding bin 21, and the pincer body 80 realizes primary stopping operation in the feeding bin 21; at this time, the bin detector 215 detects the presence of the forceps body 80; when the discharge detector 213 and the bin detector 215 both detect the existence of the pinchers, the two parts are proved to have materials, and the system controls the vibration disc to stop at the moment; otherwise, the vibration plate works.

After the material is in the feeding bin 21, the push plate retreats, the pincer body 80 in the feeding bin 21 falls on the adjusting guide rail 226 of the material pushing layer 221 due to the loss of the bottom of the movable partition plate 216, and the movement of the pincer body 80 towards the push plate retreating direction is avoided in the material baffle plate below the feeding bin 21; the pusher plate is then advanced into further feed preparation.

The material to be processed on the adjustment guide rail 226 falls onto the first processing layer 222 under the action of the first push plate 411; then all the drilling machines and the drill bits fall down simultaneously for processing; in the case of initial feeding processing, the front processing position is vacant. After the operation is finished, the second push rod 402 is pushed forwards, and after the machining operation is finished, the first push rod 403 pushes the material forwards again to fall; after the second stage of pushing is completed, the two push rods are retracted together. And then waits for the next pushing operation.

Next, the nipper bodies on the first processing layer 222 after the first process is pushed down onto the second processing layer 223, and the material newly dropped from the pusher layer 221 is pushed down onto the first processing layer 222.

The action in the third processing tier 224 is similar except that the heights of the second processing tier 223 and the third processing tier 224 are specifically designed so that the drop height of the jaw body 80 is greater than 2 times the jaw width, and the jaw body 80 is flipped over as shown in fig. 6 when dropped.

The processing is carried out in a reciprocating and circulating way, and the automatic feeding operation of the pliers body can be realized. As shown in fig. 8.

Meanwhile, only three processing stations are listed in the invention, the first is a rivet hole 805 of the forceps head 81, the second is a rivet step 806 of the forceps head 81, and the third is a grinding disc 801, which is processed from right to left in sequence according to the forceps body processing engineering diagram in fig. 8, wherein the layer heights of the second processing layer 223 and the third processing layer 224 are specially designed from the second station to the third station, so that the falling height of the forceps body 80 is higher than the falling height of 2 times the width of the forceps, and the overturning shown in fig. 8 is realized when the forceps body 80 falls.

In practice, the fine processing can be increased by adding a push plate and a corresponding processing layer. The machining is performed sequentially from right to left as shown in the forceps body machining station diagram of fig. 9.
