The power output from the motor 101 is transmitted to a power belt 102a, the power belt 102a transmits the power to a divider 102b, and a worm and gear mechanism 102c is provided inside the divider 102b to change the transmission direction of the power. The divider 102b then transmits power to the support body 91 to drive the support body 91 to rotate.

In the above technical solution, the divider 102b is adopted to automatically control the support bodies 91 of the plurality of support arms 912 to automatically rotate 120 degrees. The alignment riveting center point is more accurate and labor-saving. The segmenter 102b interfaces with a production execution system (MES). The process sequence (different rivet specification sequences) of riveting each product and each component is preset in the MES system. When rivet riveting operation is carried out each time, a riveting station (a riveting machine position) where the operation is carried out is selected in the MES system. And further inputting the serial number of the riveting component, and transmitting the riveting process sequence of the riveting component to the rivet by the MES system under the condition that the riveting station is electrified. A riveting 'operation switch' is further set on the riveting machine, and the operation switch divider automatically drives the adjusting table to rotate to the set riveting support arm position according to the preset riveting process sequence every time the operation switch divider is pressed.

Referring to fig. 7, in some embodiments, the riveting machine further comprises a control circuit 11, the control circuit 11 comprising a plurality of solenoid valves and a plurality of contact switches; each solenoid valve corresponds to one storage chamber 1a, each contact switch corresponds to one floating pin 92, and the control circuit 11 is configured to open the pneumatic component of the storage chamber 1a corresponding to the floating pin 92 in the caulking position.

As shown in fig. 7, the control circuit 11 includes a power supply 111, a first contact switch 112, a second contact switch 113, a third contact switch 114, a positioning pin normally-closed switch 115, a repeated operation normally-closed switch 116, a first feeding tank solenoid valve 117, a second feeding tank solenoid valve 118, and a third feeding tank solenoid valve 119. The first contact switch 112 and the first feed tank solenoid valve 117 are located in the same branch. The second contact switch 113 and the second feed tank solenoid valve 118 are located in the same branch. The third contact switch 114 and the third feed tank solenoid valve 119 are located in the same branch. A positioning bayonet normally closed switch 115 and a repeated operation normally closed switch 116 are positioned in the main road.

Referring to fig. 7, the positioning bayonet normally-closed switch 115 is used to ensure the operation safety, and when the bayonet is in the positioning state, the positioning bayonet normally-closed switch 115 is in the closed connection state; when the detent is retracted in the unseated state, the detent normally closed switch 115 is open. Namely, when the floating core needle adjusting table 9 is in a freely rotatable state, the bayonet is in a retraction unlocking state and the normally closed switch is in an off state, and all the feed tanks 1 are in a power-off state.

In the production process, for example, the first support arm 912 corresponds to the first rivet 12, the first contact switch 112 and the first material box 1b, and the second support arm 912 corresponds to the second rivet 12, the second contact switch 113 and the second material box 1 c. The third support arm 912 corresponds to rivet No. three 12, contact switch No. three 114 and magazine No. three 1 d. After a certain support arm 912 is selected (the selected support arm 912 corresponds to the selected rivet 12 type to be riveted, and then a certain rivet 12 of the first rivet 12, the second rivet 12 and the third rivet 12 needs to be conveyed), for example, the first support arm 912 is selected, then the first support arm 912 is stopped at the bayonet locking position and is locked, at this time, the positioning bayonet normally-closed switch 115 is switched on, and the corresponding locked first contact switch 112 is in a switching-on state. And electrifying the corresponding first feeding box 1 to release a first rivet 12 with a corresponding specification, simultaneously switching on the electromagnetic air valve power supply 111 and opening the air valve, and automatically dropping the rivet 12 into the riveting impact head along the chute after the rivet is blown out to the top end of the chute.

The repetitive operation normally closed switch 116 is normally in a closed on state. When the feeding box 1 needs to be repeatedly connected for the last time to output one rivet 12, the circuit of the feeding box 1 is disconnected once after the repeated operation normally-closed switch 116 is pressed once, one rivet 12 is in a standby state, then the repeated operation normally-closed switch 116 is loosened, the feeding box 1 is connected with the power supply 111 again, and compressed air blown by the electrified electromagnetic air valve by the rivet 12 in the standby state is blown out of one rivet 12 with the same riveting length to enter the chute.

The normally closed switch 116 for repeated operation solves the problem that the same component needs rivets with the same specification to rivet different parts, and rivets 12 with the same specification need to be output repeatedly to rivet. Each time the repeated piece is pressed, the material box 1 repeatedly conveys one rivet specification output last time into the rivet feeding port.
