A plurality of baffles 24 are evenly and fixedly arranged on the conveying chain plate of the hoist 23.

[0040] A usage method of an elevation angle drill continuous welding system includes the following usage steps:

[0041] Step 1: Start the mechanical transmission device to make the first transmission mechanism 1 and the second transmission mechanism 2 run synchronously;

[0042] The programmable logic controller controls the motor to start, so that the driving sprocket of the first transmission mechanism 1 starts to run, driving the driven sprocket of the first transmission mechanism 1 to run. Since the output end of the first transmission mechanism 1 is fixedly connected to the input end of the second transmission mechanism 2, the second transmission mechanism 2 will be driven to start running, and thus start working production;

[0043] Step 2: In the manual distribution area, the staff place the drill workpiece and the tooling workpiece on the mechanical positioning device and start the mechanical positioning device;

[0044] The drill workpiece and the tooling workpiece are placed together on the positioning structure 4. The programmable logic controller controls the driving mechanism 3 to start, and the cylinder will push the pushing block, which will push the drill workpiece and the tooling workpiece on the positioning structure 4, so that the drill workpiece and the tooling workpiece are positioned and locked;

[0045] Step 3: The driving mechanism 3 starts to run. As soon as the cylinder starts, the workpiece is assembled onto the tooling workpiece, and the tooling workpiece is assembled onto the locking part;

[0046] The drill workpiece and the tooling workpiece are first located within the arc-shaped block, and then pushed by the pushing block onto the locking part. The drill workpiece is inserted into the positioning locking rod 5 and positioned by the limit locking ring 8. The positioning locking rod 5 is inserted into the locking tube 9. By the action of the U-shaped spring 12, the limit ball can be squeezed into the limit groove, thereby realizing the positioning of the tooling workpiece, and thus completing the assembly operation;

[0047] Step 4: After the workpiece and the tooling workpiece are assembled, they run to the welding-direction conversion area, and the first positioning welding device 17 and the second positioning welding device 18 are started;

[0048] Since the output end of the first transmission mechanism 1 is fixedly connected to the input end of the second transmission mechanism 2, the output end of the first transmission mechanism 1 and the second transmission mechanism 2 run synchronously, which will drive the assembled drill workpiece and the tooling workpiece to be conveyed into the welding-direction conversion area. During the conveying process, since the arc-shaped block is fixedly installed on the second transmission mechanism 2, the assembled drill workpiece and the tooling workpiece will not be hindered and will be separated from the second transmission mechanism 2. The assembled drill workpiece and the tooling workpiece are conveyed by the first transmission mechanism 1 to the first positioning welding device 17 for the first welding. Then, through the conveying action of the first transmission mechanism 1, the flipping device is operated, and the gear 19 and the toothed plate 20 roll relative to each other, so that the drill workpiece and the tooling workpiece are flipped and continue to be conveyed to the second positioning welding device 18 for the second welding;

[0049] Step 5: After welding is completed, it runs to the workpiece unloading area, and the unloading drive device on the workpiece unloading area is started;

[0050] When the unloading drive device on the workpiece unloading area is started, the programmable controller controls the unloading cylinder 21 on the workpiece unloading area to start, pushing the ejector rod 11, so that the ejector rod 11 slides in the locking tube 9. At the same time, the stroke distance of the unloading cylinder 21 is controlled, so that the first rod 14 can push the drill workpiece out of the tooling workpiece, while the side end of the second rod 15 just contacts the side of the tooling workpiece. At this time, the spring is in a compressed state. After the drill workpiece is unloaded, the unloading cylinder 21 returns to its initial state, and the ejector rod 11 will also return to its initial state by the action of the spring;

[0051] Step 6: It runs to the tooling unloading area, and the unloading drive device on the tooling unloading area is started;

[0052] When the unloading drive device on the tooling unloading area is started, the programmable controller controls the unloading cylinder 21 on the tooling unloading area to start. The unloading cylinder 21 starts, pushing the ejector rod 11, so that the ejector rod 11 slides in the locking tube 9. At the same time, the stroke distance of the unloading cylinder 21 is controlled, so that the second rod 15 can push the tooling workpiece out of the locking part. At this time, the spring is in a compressed state. After the tooling workpiece is unloaded, the unloading cylinder 21 returns to its initial state, and the ejector rod 11 will also return to its initial state by the action of the spring;

[0053] Step 7: The tooling workpiece is conveyed to the tooling transmission device 22, and the tooling transmission device 22 is started;

[0054] The tooling workpiece falls into the guide chute and is conveyed by diversion to the input end of the tooling transmission device 22. The tooling transmission device 22 is started, and the programmable controller controls the hoist 23 to start running, which can convey the tooling workpiece to the mechanical positioning device again for the next use.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
