The first station 40, the second station 41, the third station 42 and the fourth station 43 are sequentially arranged in the track frame 2 from front to back, and the fifth station 44 is arranged on one side of the second station 41; the motor 6 drives the grinding roller 7 to rotate counterclockwise (with a rotation axis 19) through the second rotating shaft 19. Figure 1 (From the main perspective), the grinding roller 7 drives the turntable 11 to rotate through the first rotating shaft 18. Since the toggle frame 9 is slidingly connected to the first track groove 8, when the grinding roller 7 rotates counterclockwise, the first track groove 8 will drive the toggle frame 9 to rotate around the main support frame 10, thereby driving the first sliding frame 15 to move left and right through the toggle frame 9 and the vertical limit groove 48. At the same time, the second track groove 16 drives the limit rod 26 to move up and down (the fixed track frame 25 limits the limit rod 26 to only move up and down), the limit rod 26 drives the sliding track frame 27 to move up and down, and the sliding track frame 27 drives the extension frame 21 to move up and down.

[0039] The inner wall of the track frame 2 is fixedly connected with a fixed platform 23, and the fixed platform 23 is located at the fifth station 44; the height of the fixed platform 23 is the same as the bottom wall thickness of the first workpiece 20 (to ensure that the second workpiece 39 can be smoothly pulled into the first workpiece 20); a first through hole 33 is provided on the working platform 1, and the first through hole 33 is located on the right side of the second station 41, a second through hole 34 is provided on the working platform 1, and the second through hole 34 is located on the left side of the second station 41, and a connecting agent box 35 is fixedly connected to the lower end of the working platform 1, and the connecting agent box 35 is located directly below the first through hole 33; when the mounting rod 28 moves downward from the first through hole 33, the sponge brush 31 can dip the connecting agent box 35 Connecting agent; the lower end of the working platform 1 is fixedly connected to a limiting sleeve 37, and one side of the limiting sleeve 37 is slidably connected to the pushing frame 12, and a driving inclined surface 36 is provided on the pushing frame 12, and the driving inclined surface 36 is located directly below the second through hole 34. A limiting plate 38 is fixedly connected to the pushing frame 12, and one side of the pushing frame 12 is fixedly connected to a push plate 24, and a first spring 13 is sleeved on the outer side of the push plate 24; when the mounting rod 28 moves downward from the second through hole 34, the mounting rod 28 will press the driving inclined surface 36, and under the action of the inclined surface, the pushing frame 12 moves toward the limiting sleeve 37, thereby pushing the first workpiece 20 at the first station 40 to the second station 41 through the push plate 24.

[0040] The upper end of the track frame 2 is fixedly connected to the first blanking frame 3, which contains multiple groups of first workpieces 20. The upper end of the track frame 2 is fixedly connected to the second blanking frame 4, which contains multiple groups of second workpieces 39. A fixed hook 32 is provided on one side of each group of second workpieces 39.

[0041] Two sets of plasma arc welding guns 22 are fixedly connected to the upper end of the extension frame 21. The plasma arc welding guns 22 can weld the combination of the first workpiece 20 and the second workpiece 39, and the plasma arc welding guns 22 are located directly above the third workstation 42. Four sets of support legs 14 are fixedly connected to the bottom of the work platform 1.

[0042] A toggle sleeve 45 is fixedly connected to one side of the extension frame 21, and a toggle bevel 46 is slidably connected to the lower end of the toggle sleeve 45, and a second spring 47 is fixedly connected between the toggle bevel 46 and the inner wall of the toggle sleeve 45; when the toggle sleeve 45 moves to the right, the inclined side of the toggle bevel 46 contacts the first workpiece 20 at the fourth station 43, and the toggle bevel 46 will be retracted into the toggle sleeve 45 without causing any obstruction; when the toggle sleeve 45 moves to the left, the toggle bevel 46 (right-angle surface) will push the combination of the first workpiece 20 and the second workpiece 39 that have been welded at the fourth station 43 to the left, and the grinding roller 7 will grind the weld in this process to remove welding slag.

[0043] When doing specific work, Figure 1 (Device storage and transportation Figure 13 and Figure 3The state shown is the reference view. Multiple groups of first workpieces 20 are added to the first blanking frame 3, and multiple groups of second workpieces 39 are added to the second blanking frame 4. One group of first workpieces 20 falls to the first station 40, and one group of fifth station 44 falls to the fifth station 44. The motor 6 is started, and the motor 6 drives the grinding roller 7 to rotate counterclockwise (with the second rotating shaft 19) through the second rotating shaft 19. Figure 1 (From the main perspective), the grinding roller 7 drives the turntable 11 to rotate through the first rotating shaft 18. Since the toggle frame 9 is slidably connected to the first track groove 8, when the grinding roller 7 rotates counterclockwise, the first track groove 8 will drive the toggle frame 9 to rotate cyclically around the main support frame 10, thereby driving the first sliding frame 15 to move left and right through the toggle frame 9 and the vertical limit groove 48. At the same time, the second track groove 16 drives the limit rod 26 to move up and down (the fixed track frame 25 limits the limit rod 26 to only move up and down), the limit rod 26 drives the sliding track frame 27 to move up and down, and the sliding track frame 27 drives the extension frame 21 to move up and down. The specific movement process is as follows;

[0044] by Figure 14 and Figure 19 The state shown is the initial state, at this time the toggle frame 9 is at point f, the limit rod 26 is at point m, the motor 6 is started and drives the grinding roller 7 to rotate counterclockwise (by Figure 1 As the grinding roller 7 rotates counterclockwise, the device Figure 14 and Figure 19 The state motion shown is Figure 15 and Figure 20 In the state shown (the grinding roller 7 rotates 45°), during this process, since the fe segment is an arc and has the same distance from the center of the grinding roller 7, the toggle frame 9 will not rotate. At the same time, since point k is farther from the center of the turntable 11 than point m, the limit rod 26 will drop, driving the sliding track frame 27 to drop, thereby driving the extension frame 21 and the mounting rod 28 to drop (the mounting rod 28 passes through the second through hole 34). During this process, the mounting rod 28 will press the driving inclined surface 36, and under the action of the inclined surface, the push frame 12 will move toward the limiting sleeve 37, thereby pushing the first workpiece 20 at the first station 40 to the second station 41 through the push plate 24 (the distance between the limiting plate 38 and the limiting sleeve 37 is exactly equal to the distance between the first station 40 and the second station 41, which effectively prevents the push frame 12 from moving backward excessively, and the first workpiece 20 at each subsequent station will move backward in turn);

[0045] As the grinding roller 7 continues to rotate counterclockwise, the device Figure 15 and Figure 20 The state motion shown is Figure 16 and Figure 21 In the state shown (the grinding roller 7 rotates 45° counterclockwise), since the ed segment is an arc and is at the same distance from the center of the grinding roller 7, the toggle frame 9 will not rotate, and point j is closer to the center of the turntable 11 than point k. During this process, the limit rod 26 will rise;

[0046] As the grinding roller 7 continues to rotate counterclockwise, the device Figure 16 and Figure 21 The state motion shown is Figure 17 and Figure 22 In the state shown (the grinding roller 7 rotates 90° counterclockwise), since the ji segment is an arc and has the same distance from the center of the turntable 11, the limit rod 26 will not move up and down, and the toggle frame 9 slides from d to c. During this process, the toggle frame 9 will rotate counterclockwise and cooperate with the vertical limit groove 48 to drive the first sliding frame 15 to move right. During this process, the inclined side of the toggle block 46 contacts the first workpiece 20 at the fourth station 43, and the toggle block 46 will be retracted into the toggle sleeve 45 without any obstruction. The rotating hook 30 contacts the fixed hook 32 on the second workpiece 39 at the fifth station 44. The rotating hook 30 can rotate around the rotating frame 29. Under normal circumstances, Figure 5 As shown, when the rotating hook 30 hits the fixed hook 32 from left to right, the rotating hook 30 can rotate around the rotating frame 29 to avoid the fixed hook 32 (the two states are as follows Figure 24 shown, the first case);

[0047] As the grinding roller 7 continues to rotate counterclockwise, the device Figure 17 and Figure 22 The state motion shown is Figure 18 and Figure 23 In the state shown (the grinding roller 7 rotates 45° counterclockwise), since the cb segment is an arc, the toggle frame 9 does not rotate. Since point h is farther from the center of the turntable 11 than point i, the limit rod 26 will descend during this process (the mounting rod 28 passes through the first through hole 33), and the sponge brush 31 is dipped in the connecting agent in the connecting agent box 35;

[0048] As the grinding roller 7 continues to rotate counterclockwise, the device Figure 18 and Figure 23 The state motion shown is Figure 13 and Figure 3 In the state shown (the grinding roller 7 rotates 45° counterclockwise), since the ba segment is an arc, the toggle frame 9 will not rotate. Since the g point is closer to the center of the turntable 11 than the h point, the limit rod 26 will rise during this process, and the mounting rod 28 will rise. During this process, the rotating hook 30 will be hung upward on the fixed hook 32 (the two states are as follows Figure 24 shown, the second case).

[0049] As the grinding roller 7 continues to rotate counterclockwise, the device Figure 13 and Figure 3 The state motion shown is Figure 14 and Figure 19In the state shown (the grinding roller 7 rotates 90° counterclockwise), during this process, since the gm segment is an arc, the limit rod 26 will not move up and down, and the toggle frame 9 slides from a to f. During this process, the toggle frame 9 will rotate clockwise around the main support frame 10, and cooperate with the vertical limit groove 48 to drive the first sliding frame 15 to move left. During this process, on the one hand, the sponge brush 31 will brush the connector on the inner wall of the first workpiece 20 at the second station 41, and the rotating hook 30 drives the second workpiece 39 to be inserted into the first workpiece 20 on the second station 41 through the fixed hook 32. At the same time, two groups of plasma arc welding guns 22 are started to weld the joints of the first workpiece 20 and the second workpiece 39 at the third station 42 (the plasma arc welding gun 22 stops immediately after welding is completed). At the same time, toggling the bevel 46 (right-angle surface) will push the combination of the first workpiece 20 and the second workpiece 39 welded at the fourth station 43 to the left. During this process, the grinding roller 7 will grind the weld and remove welding slag.

[0050] By repeating the above operations, the first workpiece 20 and the second workpiece 39 can be automatically blanked and assembled, the connecting agent can be automatically dipped and applied, the weld can be welded, and the weld slag can be ground off.

[0051] Finally: The above are only 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 principles of the present invention should be included in the scope of protection of the present invention.
