Figure 4 Turn into Figure 2 The arc-shaped toothed plate 17 will slowly rotate counterclockwise to return. This motion feature is a quick return feature. The arc-shaped toothed plate 17 drives the turntable 4 to quickly rotate 180 degrees counterclockwise through the gear 26 and the first rotating shaft 19 (the whole process takes 5 seconds, which is short and improves the overall work efficiency). As the Z-shaped rotating rod 28 continues to rotate counterclockwise, the Z-shaped rotating rod 28 will drive the arc-shaped toothed plate 17 to slowly rotate 60 degrees counterclockwise ( Figure 4As a reference, in this process, the arc gear plate 17 will rotate slowly because the Z-shaped rotating rod 28 needs to rotate at a large angle. The arc gear plate 17 drives the rotating disk 4 to rotate 180 degrees clockwise rapidly through the gear 26 and the first rotating shaft 19 (by Figure 4 Turn into Figure 2 state, the whole process takes 10s).

[0026] The upper end of the bottom plate 1 is fixedly connected to a plurality of first support legs 7, and the upper ends of the plurality of first support legs 7 are fixedly connected to an arc frame 9, on which a first track groove 8 is arranged, and on which a second track groove 10 is arranged, and there is a step between the second track groove 10 and the first track groove 8 (by Figure 6 As shown, the first track groove 8 is higher than the second track groove 10, and the height difference between the two is equal to the shell thickness of the second workpiece 32, which facilitates the insertion of the first workpiece 31 into the second workpiece 32); the upper end of the bottom plate 1 is fixedly connected with the second support leg 12, and the first blanking frame 11 is fixedly connected to one side of the second support leg 12, and the first blanking frame 11 is located above the first track groove 8, and multiple groups of first workpieces 31 are installed in the first blanking frame 11, the upper end of the bottom plate 1 is fixedly connected with the third support leg 13, and the second blanking frame 14 is fixedly connected to one side of the third support leg 13, and the second blanking frame 14 is located above the second track groove 10, and multiple groups of second workpieces 32 are installed in the second blanking frame 14; the turntable 4 is quickly rotated 180 degrees counterclockwise ( Figure 2 During the process of the second blanking frame 14 being welded, the inclined scraper 25 will drive the first workpiece 31 and the second workpiece 32 combination that have been welded at the bottom of the second blanking frame 14 to press the inclined stopper 16 (under the action of the inclined surface of the inclined stopper 16, the inclined stopper 16 will compress the second spring 36 and collect it into the fixed frame 15), and the welded first workpiece 31 and the second workpiece 32 combination that have been welded will eventually fall into the collecting frame 2. When the inclined scraper 25 leaves the bottom of the second blanking frame 14, a new set of second workpieces 32 will fall into the second track groove 10. When the push plate 3 passes under the first blanking frame 11, it will drive the first workpiece 31 to rotate counterclockwise ( Figure 1 The first workpiece 31 is inserted into the second workpiece 32 (due to the obstruction of the oblique stopper 16, the friction force of the first workpiece 31 during the insertion of the second workpiece 32 is not enough to drive the second workpiece 32 to press the oblique stopper 16, and the oblique stopper 16 is used to block the second workpiece 32 to prevent the second workpiece 32 from moving during the insertion of the first workpiece 31). Figure 3 and Figure 4 In the state shown (the turntable 4 rotates counterclockwise to the limit), it is still inserted between the first blanking frame 11 and the first track groove 8 to prevent the first workpiece 31 from falling.

[0027] A fixed groove 23 is provided on the arc frame 9, and a first spring 24 is fixedly connected to one side of the inner wall of the fixed groove 23, and an oblique scraper 25 is fixedly connected to one end of the first spring 24, and the oblique scraper 25 is slidably snap-connected to the fixed groove 23, and a plasma arc welding gun 22 is fixedly connected to the inner side of the turntable 4; the plasma arc welding gun 22 can weld the combination of the first workpiece 31 and the second workpiece 32 (in the process of the turntable 4 rotating 180 degrees clockwise, the turntable 4 rotates slowly in this process, and the plasma arc welding gun 22 welds the weld when passing through the combination of the first workpiece 31 and the second workpiece 32), and the oblique scraper 25 can push down the welding to complete the first workpiece 31 and the second workpiece 32, and can scrape off the welding slag of the weld of the first workpiece 31 and the second workpiece 32 on the other hand.

[0028] A welding oil box 6 is fixedly connected to the upper end of the turntable 4, a sponge brush 5 is fixedly connected to the outer side of the turntable 4, and the sponge brush 5 is connected to the welding oil box 6 through a pipeline. A pump is arranged in the welding oil box 6, and a push plate 3 is fixedly connected to one side of the turntable 4. The pump in the welding oil box 6 can send the welding oil to the sponge brush 5 through the pipeline, and the sponge brush 5 can brush welding oil on the unwelded welds on the first workpiece 31 and the second workpiece 32 (in the process of the turntable 4 rotating 180 degrees counterclockwise, the sponge brush 5 brushes welding oil on the welds of the first workpiece 31 and the second workpiece 32).

[0029] The upper end of the base plate 1 is fixedly connected to the fourth supporting leg 20, the upper end of the fourth supporting leg 20 is fixedly connected to the fixed frame 15, the fixed frame 15 is fixedly connected to the second spring 36, one end of the second spring 36 is fixedly connected to the oblique stopper 16, and the upper end of the base plate 1 is fixedly connected to the collecting frame 2; when the push plate 3 passes under the first blanking frame 11, it will drive the first workpiece 31 to rotate counterclockwise and insert it into the second workpiece 32 (due to the obstruction of the oblique stopper 16, the friction force of the first workpiece 31 during the insertion of the second workpiece 32 is not enough to drive the second workpiece 32 to press the oblique stopper 16, and the second workpiece 32 will not move on the second track groove 10).

[0030] The device is used for welding metal parts. The device is placed on a placement table ( Fig.12 )superior.

[0031] When working specifically, the initial state is as follows Figure 1 and Figure 2 As shown, a group of welded second workpieces 32 and first workpieces 31 are added to the second blanking frame 14, and the welded second workpieces 32 and first workpieces 31 fall into the second track groove 10. Then, multiple groups of second workpieces 32 are added to the second blanking frame 14, and multiple groups of first workpieces 31 are added to the first blanking frame 11. The bottom group of first workpieces 31 falls into the first track groove 8. The motor 27 drives the Z-shaped rotating rod 28 to rotate counterclockwise through the motor shaft ( Figure 1 As shown), the arc-shaped tooth plate 17 is quickly driven to rotate 60 degrees clockwise ( Figure 1 and Figure 2 As shown by Figure 2 Turn into Figure 4 In this process, the arc-shaped toothed plate 17 will rotate rapidly clockwise because the angle required for the Z-shaped rotating rod 28 to rotate is small. On the contrary, the arc-shaped toothed plate 17 will slowly rotate counterclockwise to return. This motion characteristic is a quick return characteristic. The arc-shaped toothed plate 17 drives the rotating disk 4 to rotate rapidly counterclockwise by 180 degrees (by the gear 26 and the first rotating shaft 19). Figure 2 Turn into Figure 4 The whole process takes 5s, which is short and improves the overall work efficiency). During this process, the inclined scraper 25 will drive the first workpiece 31 and the second workpiece 32 assembly that have been welded at the bottom of the second blanking frame 14 to press the inclined stopper 16 (under the action of the inclined surface of the inclined stopper 16, the inclined stopper 16 will compress the second spring 36 and collect it into the fixed frame 15). The welded first workpiece 31 and the second workpiece 32 assembly will finally fall into the collecting frame 2. When the inclined scraper 25 leaves the bottom of the second blanking frame 14, a new set of second workpieces 32 fall into the second track groove 10. When the push plate 3 passes under the first blanking frame 11, it will drive the first workpiece 31 to rotate counterclockwise and insert it into the second workpiece 32 (due to the obstruction of the inclined stopper 16, the friction force of the first workpiece 31 in the process of inserting the second workpiece 32 is not enough to drive the second workpiece 32 to press the inclined stopper 16). Figure 3 and Figure 4 In the state shown (the turntable 4 rotates counterclockwise to the limit), it is still inserted between the first blanking frame 11 and the first track groove 8 to prevent the first workpiece 31 from falling, and at the same time, the sponge brush 5 brushes welding oil on the weld of the first workpiece 31 and the second workpiece 32 combination located on the second track groove 10;

[0032] As the Z-shaped rotating rod 28 continues to rotate counterclockwise ( Figure 2 As shown), the Z-shaped rotating rod 28 will drive the arc-shaped toothed plate 17 to slowly rotate 60 degrees counterclockwise ( Figure 2 As shown in the figure, in this process, since the Z-shaped rotating rod 28 needs to rotate at a large angle, the arc-shaped toothed plate 17 will rotate slowly), and the arc-shaped toothed plate 17 drives the rotating disk 4 to rotate 180 degrees clockwise quickly through the gear 26 and the first rotating shaft 19 (by Figure 4 Turn into Figure 2state, the whole process takes 10s), the fourth support leg 20 starts when passing the first workpiece 31 and the second workpiece 32 combination on the second track groove 10, and welds the first workpiece 31 and the second workpiece 32 combination. The welding process takes a long time to improve the welding effect, and then the oblique scraper 25 scrapes off the welding slag. Since there is a step welding between the first track groove 8 and the second track groove 10, the first workpiece 31 and the second workpiece 32 combination completed will not move. When the push plate 3 is separated from the bottom of the first blanking frame 11, a group of first workpieces 31 fall into the first track groove 8. Repeating the above operations can complete the automatic blanking, automatic assembly, automatic brushing of welding oil, automatic welding, automatic removal of welding slag, and automatic unloading of the first workpiece 31 and the second workpiece 32. The oblique scraper 25 can push down the first workpiece 31 and the second workpiece 32 to complete the welding, and on the other hand, it can scrape off the welding slag of the weld of the first workpiece 31 and the second workpiece 32.

[0033] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
