Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] Referring to Figures 1-3 A workpiece conveying mechanism for thrust rod friction welding, comprising a preceding friction welding station (i.e. preceding friction welding equipment) 3 and a subsequent friction welding station (i.e. subsequent friction welding equipment) 4 for welding a thrust rod body 1 and an end head 2, the preceding friction welding station 3 and the subsequent friction welding station 4 are respectively provided with a feeding station and a discharging station on opposite sides, a conveying component for conveying workpieces (i.e. a rod body 1 with an end head fixedly connected at one end) is arranged between the feeding station and the discharging station, three photoelectric switches 5 for detecting whether there is material are arranged side by side on one side of the discharging station, and three indicator lights 6 are arranged on one side of the feeding station in a superposed manner; the mechanism further comprises a PLC 7, the PLC 7 is electrically connected with the three detection elements and the three indicator lights respectively and controls the operation of the conveying component.

[0021] In the utility model, the feeding station and the discharging station each comprise a platform 8 fixed to a support, and three first V-shaped pads 9 are fixedly connected to the two sides of the platform 8, and the three first V-shaped pads 9 on the two sides correspond one by one.

[0022] Therefore, the feeding station and the discharging station each provide three storage stations for storing workpieces, and the V-shaped pads ensure that the workpieces can be kept stable during storage.

[0023] In the utility model, the conveying component adopts a chain conveyor 10, and a plurality of second V-shaped pads 11 are fixedly connected to the chains on the two sides of the chain conveyor 10 along the circumferences thereof, and the plurality of second V-shaped pads 11 on the two sides correspond one by one.

[0024] Therefore, the chain conveyor 10 is adopted to convey workpieces, and the V-shaped pads are also arranged to ensure that the workpieces can be kept stable during storage.

[0025] In the utility model, the width of the platform 8 and the chain conveyor 10 is less than the length of the length of the push rod body 1, so that the end head 2 at one end of the rod body 1 can be in a suspended state when the workpiece is stored and conveyed, thereby facilitating the storage and conveying of the workpiece.

[0026] In the utility model, the three indicator lamps 6 correspond to the three photoelectric switches 5 one by one, and each indicator lamp comprises a red indicator lamp and a green indicator lamp, wherein the red indicator lamp is lit to indicate that there is material waiting, and the green indicator lamp is lit to indicate that there is no material waiting.

[0027] In the utility model, the driving motor 12 of the chain conveyor 10 is provided with a normally closed relay 13 in the power supply circuit, and the driving motor 12 is electrically connected with a frequency converter 14, and the PLC 7 is electrically connected with the relay 13 and the frequency converter 14.

[0028] Therefore, by arranging the relay 13, the driving motor 12 is controlled by the PLC 7, that is, the chain conveyor 10 is controlled to start and stop; by arranging the frequency converter 14, the driving motor 12 is adjusted by the PLC 7 through the frequency converter 14, that is, the running speed of the chain conveyor 10 is controlled.

[0029] The utility model will be further described below in combination with the drawings:

[0030] When in use, the one end of the rod body 1 and one end head are friction welded at the preceding friction welding station (i.e. the preceding friction welding device) 3, so that the one end of the rod body 1 is fixedly connected with the end head.

[0031] After the friction welding is completed, the workpiece (i.e. the rod body 1 with the end head fixedly connected at one end) is placed on the platform 8 of the feeding station by artificial, and then placed on the feeding end of the chain conveyor 10 one by one, or directly placed on the feeding end of the chain conveyor 10 nearby. The platform 8 of the feeding station can provide three storage stations.

[0032] The chain conveyor 10 conveys the workpiece to the subsequent friction welding station (i.e. the subsequent friction welding device) 4, and the workpiece is placed on the platform 8 of the discharging station by artificial for storage, and then sent to the subsequent friction welding station one by one for friction welding, so that the other end of the rod body 1 is fixedly connected with the other end head, and the push rod is obtained.

[0033] After the friction welding is completed, the push rod is taken out by artificial.

[0034] When the processing progress of the preceding friction welding station 3 and the subsequent friction welding station 4 inevitably appears inconsistent, the chain conveyor 10 can provide three conveying working modes under the control of the PLC 7, which are as follows:

[0035] 1. When all three photoelectric switches 5 detect that there is a workpiece stored, PLC7 sends a disconnect command to relay 13. Relay 13 disconnects, drive motor 12 stops working, and chain conveyor 10 stops running. On the other hand, all three red indicator lights 6 are lit up, indicating that the unloading station is in a fully saturated "material waiting" state, prompting the operator of the preceding friction welding station 3 to stop processing.

[0036] 2. When some of the three photoelectric switches 5 detect that there is a workpiece stored, the relay 13 remains closed. The PLC 7 sends a deceleration command to the frequency converter 14, which controls the drive motor 11 to run at low speed, so that the chain conveyor 10 runs at low speed, reducing the conveying speed of the workpiece. On the other hand, it lights up the corresponding part of the red indicator lights and the other part of the green indicator lights in the three indicator lights 6, indicating that the unloading station is in a "material waiting" state that is not fully saturated, prompting the operator of the preceding friction welding station 3 to slow down the processing progress in a timely manner.

[0037] 3. When none of the three photoelectric switches 5 detects any workpieces stored, the relay 13 remains closed. The PLC 7 sends a speed-up command to the frequency converter 14, which controls the drive motor 11 to run normally, so that the chain conveyor 10 runs at normal speed, reducing the conveying speed of the workpieces. On the other hand, all three green indicator lights 6 are lit up, indicating that the unloading station is in a "no material waiting" state, prompting the operator of the preceding friction welding station 3 to speed up the processing progress as appropriate.

[0038] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0039] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
