The technical problem to be solved by the present invention is that the existing welding device for fixing parts of a port conveyor only has single welding and cannot achieve workpiece assembly, weld grinding, rotational running-in of workpieces, and automatic unloading, resulting in low work efficiency.

[0004] To achieve the above object, the present invention provides the following technical solution: A plasma arc welding machine for fixing parts of a port conveyor, including a fixing plate. A rotating frame is rotatably connected to the upper end of the fixing plate. A first turntable is rotatably connected to the outer surface of the rotating frame. A groove is provided at the upper end of the first turntable. A plurality of groups of hexagonal holes are uniformly provided on the cylindrical outer surface of the first turntable. One side of the inner wall of each group of hexagonal holes is fixedly connected with a magnet with a hole. A circular hole is provided on one side of the magnet with a hole. A second workpiece is inserted into each group of hexagonal holes. A first workpiece is sleeved outside the second workpiece. The first workpiece includes two semi-buckle components, and the two semi-buckle components are pre-fixed by spot welding. A driven helical gear is provided on one side of each semi-buckle component. One side of the motor extends to be provided with a motor shaft, and one end of the motor shaft is fixedly connected with a main rotating shaft. A limiting wheel is fixedly connected to the cylindrical outer surface of the main rotating shaft. A limiting grinding track is provided on the limiting wheel, and the limiting wheel is adapted to the first workpiece. A bevel gear block with a notch is fixedly connected to the side of the limiting wheel close to the motor, and the bevel gear block with a notch is adapted to the driven helical gear. One end of the main rotating shaft is fixedly connected with a second turntable, and a bevel convex block is fixedly connected to one side of the second turntable.

[0005] In a preferred embodiment, a limiting frame is fixedly connected to the upper end of the fixing plate. A blanking frame is fixedly connected to the upper end of the limiting frame, and a plurality of groups of first workpieces are placed in the blanking frame. Two springs are fixedly connected to one side of the limiting frame. The same pushing block is fixedly connected to one side of the two springs, and the pushing block is slidably connected to the limiting frame.

[0006] In a preferred embodiment, a cylinder is fixedly connected to the upper end of the fixed plate. One end of the cylinder is provided with a telescopic rod extending therefrom. One end of the telescopic rod is fixedly connected to an arc-shaped plate. Two sets of plasma arc welders are fixedly connected to the arc-shaped plate, and the plasma arc welders are opposite to a set of first workpieces in position.

[0007] In a preferred embodiment, a notch groove is provided on one side of the fixed plate, and the limit grinding track is located in the notch groove.

[0009] The technical effects and advantages of the present invention:

[0010] The motor drives the main rotating shaft and the second turntable to rotate clockwise through the motor shaft (taking Figure 1 as a reference). On the one hand, when the first workpiece at point d slides to the end of the limit grinding track and disengages, it can cause the first turntable to rotate one station (rotate counterclockwise, taking Figure 4 as a reference). At the same time, the next group of first workpieces slide into the limit grinding track, thereby driving the first turntable to continuously rotate intermittently around the rotating frame (the first turntable rotates one station every time the main rotating shaft rotates one circle). At the same time, the grinding layer in the limit grinding track can grind the weld seam of the first workpiece. The notched helical block can engage with the driven helical teeth at point e. During rotation, the running-in of the rotation of the second workpiece and the first workpiece can be realized. The push block can be pushed by the inclined surface convex block. On the one hand, when the inclined surface convex block pushes the push block, it will push the first workpiece that has fallen into the limit frame directly below the blanking frame, so that the first workpiece is sleeved and fixed with the second workpiece at point b. On the other hand, the push block will drive the push rod to insert into the circular hole at point f through the connecting frame. The push rod can eject the workpiece processed at station f under the drive of the connecting frame, thereby ejecting the combination of the first workpiece and the second workpiece to realize unloading; the entire device can complete the assembly of the first workpiece and the second workpiece, the conversion of stations, the welding of the joints of the first workpiece, the grinding of the weld seam, drive the first workpiece to rotate to realize the running-in of the rotation of the second workpiece and the first workpiece, and finally complete unloading.

Detailed implementation manners

[0022] Consisting of Figures 1-9, the present invention provides a plasma arc welding machine for port conveyor fasteners, including a fixing plate 1. A rotating frame 7 is rotatably connected to the upper end of the fixing plate 1. A first turntable 5 is rotatably connected to the outer surface of the rotating frame 7. A groove 8 is provided at the upper end of the first turntable 5. A plurality of groups of hexagonal holes 3 are evenly arranged on the cylindrical outer surface of the first turntable 5. On one side of the inner wall of each group of hexagonal holes 3, a magnet with a hole 29 is fixedly connected. A circular hole 9 is provided on one side of the magnet with a hole 29. A second workpiece 6 is inserted into each group of hexagonal holes 3. A first workpiece 2 is sleeved on the outer side of the second workpiece 6. The first workpiece 2 includes two semi-buckle components 30. The two semi-buckle components 30 are pre-fixed by spot welding (the welding spot is located at point g. The first workpiece 2 is composed of two semi-buckle components 30 spot-welded together. The spot-welded first workpiece 2 is easy to deform, which is beneficial to press fitting). On one side of each semi-buckle component 30, a driven helical gear 28 is provided. One side of the motor 20 extends to be provided with a motor shaft. One end of the motor shaft is fixedly connected to a main rotating shaft 17. A limiting wheel 25 is fixedly connected to the cylindrical outer surface of the main rotating shaft 17. A limiting grinding track 26 is provided on the limiting wheel 25 (there are two notches on the limiting grinding track 26 and the limiting wheel 25, one for entry and one for exit), and the limiting wheel 25 is adapted to the first workpiece 2 (the width of the limiting grinding track 26 is adapted to the width of the two opposite welding surfaces of the first workpiece 2). A bevel gear block 27 with a notch is fixedly connected to the side of the limiting wheel 25 close to the motor 20, and the bevel gear block 27 with a notch is adapted to the driven helical gear 28. One end of the main rotating shaft 17 is fixedly connected to a second turntable 15. A bevel convex block 16 is fixedly connected to one side of the second turntable 15. The motor 20 drives the main rotating shaft 17 and the second turntable 15 to rotate through the motor shaft. On the one hand, during the process that the first workpiece 2 at the d-point station slides to the end of the limiting grinding track 26 (the notch on the limiting wheel 25) and disengages (the bevel surface contacts the first workpiece 2), the first turntable 5 can be rotated by one station, and at the same time, the next group of first workpieces 2 slides into the limiting grinding track 26, so as to drive the first turntable 5 to continuously rotate intermittently around the rotating frame 7 (the first turntable 5 rotates by one station every time the main rotating shaft 17 rotates one circle). One end of the second workpiece 6 is a regular hexagonal cylinder, and the other end is a frustum-like shape. A grinding layer is provided on the inner wall of the limiting grinding track 26. The grinding layer in the limiting grinding track 26 can grind the weld of the first workpiece 2.

[0023] The upper end of the fixed plate 1 is fixedly connected with a limit frame 14. The upper end of the limit frame 14 is fixedly connected with a blanking frame 10. A plurality of groups of first workpieces 2 are placed in the blanking frame 10 (the two opposite welding surfaces of the first workpiece 2 are in a vertical state). One side of the limit frame 14 is fixedly connected with two groups of springs 13. One side of the two groups of springs 13 is fixedly connected with the same group of push blocks 12. The push blocks 12 are slidably connected with the limit frame 14. The main rotating shaft 17 can drive the second turntable 15 to rotate. When the inclined surface convex block 16 rotates to the position of the push block 12, it will push the push block 12. When the inclined surface convex block 16 pushes the push block 12, it will push the first workpiece 2 that falls into the limit frame 14 directly below the blanking frame 10, so that the first workpiece 2 is sleeved and fixed with the second workpiece 6 at the b-point station (the first workpiece 2 is composed of two semi-buckle components 30 spot-welded together. The spot-welded first workpiece 2 is easy to deform, which is beneficial to press-fitting).

[0024] The upper end of the push block 12 is fixedly connected with a connecting frame 11. One side of the connecting frame 11 is fixedly connected with a pushing round rod 4. The pushing round rod 4 is adapted to the circular hole 9. When the push block 12 is pushed by the inclined surface convex block 16, it will drive the pushing round rod 4 to insert into the circular hole 9 at the f-point station through the connecting frame 11, so as to eject the combination of the first workpiece 2 and the second workpiece 6. The ejected combination of the first workpiece 2 and the second workpiece 6 will fall from the blanking hole 31.

[0025] The upper end of the fixed plate 1 is fixedly connected with a cylinder 21. One end of the cylinder 21 extends with a telescopic rod 22. One end of the telescopic rod 22 is fixedly connected with an arc-shaped plate 24. Two groups of plasma arc welders 23 are fixedly connected to the arc-shaped plate 24. The plasma arc welders 23 are opposite to the position of a group of first workpieces 2. The cylinder 21 drives the arc-shaped plate 24 to push forward through the telescopic rod 22. The plasma arc welders 23 can weld the gap between the two semi-buckle components 30 (since the plasma arc welders 23 are inclined relative to the first workpiece 2 at the position shown by the c point, the plasma arc welders 23 can weld the three-sided seams of the two semi-buckle components 30).

[0026] A notch groove 19 is arranged on one side of the fixed plate 1. The limit grinding track 26 is located in the notch groove 19. The lower end of the fixed plate 1 is fixedly connected with a plurality of support legs 18. A blanking hole 31 is arranged at the upper end of the fixed plate 1.

[0027] This device is used for welding the fixing parts of the port conveyor. This device is placed on the workbench( Figure 7 )

[0028] Specifically during operation, first place the second workpiece 6 and the first workpiece 2 according to Figure 1First, assemble the shown state. Rotate the first turntable 5 so that the assembled combination of the second workpiece 6 and the first workpiece 2 is transferred into the limit grinding track 26. Add multiple groups of the first workpiece 2 into the blanking frame 10. Start the motor 20. The motor 20 drives the main rotating shaft 17 and the second turntable 15 to rotate clockwise through the motor shaft (with Figure 1 as a reference). On the one hand, when the first workpiece 2 at the d point position slides to the end of the limit grinding track 26 (the notch on the limit wheel 25) and disengages, it can make the first turntable 5 rotate one station (rotate counterclockwise, with Figure 4 as a reference). At the same time, the next group of the first workpiece 2 slides into the limit grinding track 26, thereby driving the first turntable 5 to continuously rotate intermittently around the rotating frame 7 (the first turntable 5 rotates one station every time the main rotating shaft 17 rotates one circle). Subsequently, the inclined surface convex block 16 rotates to the push block 12 and pushes the push block 12. The manipulator continuously supplements the second workpiece 6 at the a point station. When the second workpiece 6 stays at the b point station (during the stay, the station at the d point position is in the grinding state), when the inclined surface convex block 16 pushes the push block 12, it will push the first workpiece 2 that has fallen into the limit frame 14 directly below the blanking frame 10, so that the first workpiece 2 is sleeved and fixed with the second workpiece 6 at the b point station. When the combination of the first workpiece 2 and the second workpiece 6 moves to the station shown at c point and stays, the cylinder 21 and the plasma arc welding torch 23 are started. The cylinder 21 drives the arc-shaped plate 24 to push forward through the telescopic rod 22, and the plasma arc welding torch 23 welds the gap between the two semi-buckle assemblies 30 (since the plasma arc welding torch 23 is inclined relative to the first workpiece 2 at the station shown at c point, the plasma arc welding torch 23 can weld the three-sided seams of the two semi-buckle assemblies 30). The telescopic rod 22 contracts back to the original position. When the combination of the first workpiece 2 and the second workpiece 6 moves to the station shown at d point, on the one hand, the limit grinding track 26 can guide the combination of the first workpiece 2 and the second workpiece 6, and on the other hand, the inner wall of the limit grinding track 26 can grind the weld seam. At the same time, the notched helical block 27 can engage with the driven helical gear 28 at the e point station. Since the second workpiece 6 is inserted into the hexagonal hole 3 and cannot rotate, the rotation of the notched helical block 27 can drive the first workpiece 2 to rotate relative to the second workpiece 6 through the driven helical gear 28, realizing the running-in of the rotation between the second workpiece 6 and the first workpiece 2. When the combination of the first workpiece 2 and the second workpiece 6 moves to the f point station, when the push block 12 is pushed by the inclined surface convex block 16, it will drive the push round rod 4 to insert into the circular hole 9 at the f point station through the connecting frame 11, thereby ejecting the combination of the first workpiece 2 and the second workpiece 6. The ejected combination of the first workpiece 2 and the second workpiece 6 will fall from the blanking hole 31 and can be collected with a collecting frame.

[0029] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
