Description

Technical Field

[0001] The invention relates to the technical field of welding turnover devices, in particular to a turnover device for welding loader parts. Background Art

[0002] During the manufacturing process of loaders, many parts and other components are needed for welding and assembly. Plasma arc welding is a welding method that uses plasma arc as a heat source. It has a large penetration force and welding speed, and the weld quality is high, the deformation is small, and the spatter is small. It can be used in the welding of loader components such as frames and transmission components to ensure their load-bearing capacity and service life. During the welding process, the components need to be clamped to make the welding more stable. The clamp not only has a fixing function, but can also be used to flip the workpiece for easy processing.

[0003] In the prior art, a Chinese patent with publication number CN112719749B discloses a flipping device for welding automobile sheet metal parts, which includes a processing table, and bottom columns are fixedly installed on the left and right sides of the bottom end of the processing table, a control box is fixedly installed on the right side of the processing table, a side block is fixedly installed on the right side of the top of the processing table, a clamping ring is fixedly installed on the right side of the side block, and a flipping assembly is movably connected to the right side of the top of the processing table. The winding wheel is rotated by the control box to shrink the wire rope, and the shrinkage of the wire rope drives the baffle to rotate through the wire wheel. After the baffle rotates, it collides with the mounting rod. Through the winding of the wire rope, the baffle and the mounting rod no longer block the movable ball. At the same time, the control box rotates the center rod, and the rotation of the center rod drives the movable ball to rotate on the inner wall of the fixed disk through the connecting rod, thereby rotating the entire workpiece, and after reaching the specified position, the workpiece is continuously fixed by the control box.

[0004] However, the above patent has some shortcomings. In actual use, the above patent clamps the object to be welded by two clamping rings. However, welding is to weld two independent objects into one object. Therefore, during welding, in order to ensure the quality of welding, the welding surfaces of the two objects need to be on the same level. The clamping ring of the above patent does not set a limit for the two objects. It is necessary to continuously adjust the positions of the two objects during clamping to ensure that they are on the same plane, which affects the welding efficiency. Therefore, a flip device for welding loader parts is proposed to solve the above problem. Summary of the invention

[0016] Compared with the prior art, the present invention has the following significant advantages:

[0017] First, the present invention drives the rotation of the rotating plate through the motor, and then drives the rotation of the two connecting rods, so that the fixing frame 1 and the fixing frame 2 move toward or away from each other. When the fixing frame 1 and the fixing frame 2 move toward each other, the rotating hoops arranged on the fixing frame 1 and the fixing frame 2 drive the rotating drum 1 and the rotating drum 2 to move toward each other. The horizontal movement of the rotating drum 1 drives the movement of the U-shaped drum. The movement of the U-shaped drum drives the piston arranged inside and the trapezoidal block 1 arranged on the top of the piston to follow the movement. When the trapezoidal block 1 contacts the trapezoidal plate, the piston is squeezed, and the U-shaped drum is moved. The compressed air inside the cylinder will reach the inside of the sealed cylinder through the air outlet pipe, pushing the T-shaped plate to slide inside the sealed cylinder, thereby driving the sliding of the trapezoidal block 2. The sliding of the trapezoidal block 2 can squeeze the driving rod, causing the driving rod to drive the clamping ring 1 to move. The balancing slide bar can synchronously drive the clamping ring 1 on the rotating cylinder 1 to move when the clamping ring 1 on the rotating cylinder 1 moves, so that the components clamped on the rotating cylinder 1 and the rotating cylinder 2 can ensure synchronous movement and be on the same horizontal plane during plasma arc welding, thereby improving the welding effect.

[0018] Secondly, the present invention drives the rotating rod 1 and the rotating rod 2 to rotate through the movement of the clamping ring 1, thereby driving the other rotating rod 1 and the other rotating rod 2 to rotate through the action of the cross limit groove and the limit block, realizing the synchronous movement of the clamping ring 2, thereby clamping the component. After clamping, the electromagnetic valve is opened to close the air flow of the air outlet pipe, so that the air pressure inside the sealing gas cylinder is constant, and the driving of the clamping ring 1 is kept stable. Through the synchronous movement between the clamping ring 1 and the clamping ring 2, the centering of the component clamping can be improved, thereby improving the accuracy of the component clamping and further improving the welding effect.

[0019] Secondly, the present invention drives the plasma arc welding device to descend to the welding surface of the component to be welded by the arranged cylinder to perform welding. When the plasma arc welding device descends, it drives the connecting rod to descend synchronously, and the descent of the connecting rod can drive the rectangular frame to descend. The descent of the rectangular frame synchronously drives the toothed plate arranged inside it to descend. When the toothed plate descends, since the tooth teeth direction of the active gear is opposite to the tooth teeth direction of the toothed plate, no meshing relationship is generated during descent. The arranged compression spring can achieve the avoidance of the toothed plate when the toothed plate descends. After welding is completed, the cylinder is retracted to drive the plasma arc welding device to rise, which can drive the rotating drum 2 to flip over, and then drive the welded component to flip over. After flipping, the toothed plate returns to the initial position, and then the plasma arc welding device descends again to weld the other side of the component. By flipping the component that moves synchronously with the plasma arc welding device, the accuracy of welding can be improved after flipping.

[0020] The invention solves the problem that the existing clamping ring does not set a limit for the two objects, and the positions of the two objects need to be constantly adjusted during clamping to ensure that they are on the same plane, which affects the welding efficiency.

A fixed plate 808 is fixedly connected to one side of the U-shaped cylinder 809. Two arc-shaped connecting plates 811 are fixedly connected to one side of the fixed plate 808. The two arc-shaped connecting plates 811 are respectively rotatably connected to the inner walls of the circular groove 806 opened on the flush component 7, and the U-shaped cylinder 809 and the rotating cylinder 701 can be connected through the arc-shaped connecting plates 811.

[0038] like Figure 2 and 3 As shown, the flush assembly 7 includes a rotating drum 1 701 and a rotating drum 2 10 which are rotatably connected to the inner walls of the two rotating hoops 6 respectively, a circular groove 806 is provided on one side of the rotating drum 1 701, and a fixed hoop 803 is fixedly connected to the surface of the rotating drum 1 701. A cross limiting groove 702 is provided on the inner wall of one side of the rotating drum 1 701 and the rotating drum 2 10, and a plurality of limiting blocks 707 are slidably connected to the inner wall of the cross limiting groove 702.

[0039] The two rotating rods 1 703 and 2 704 are rotatably connected via a fixed shaft, wherein one end of the two fixed shafts is fixedly connected to a clamping ring 1 705 and a clamping ring 2 706, respectively. Figure 4, it can be seen that the existence of the fixed axis, the interior of the rotating drum 1 701 and the rotating drum 2 10 are both provided with a clamping ring 1 705 and a clamping ring 2 706.

[0040] The opposite surfaces of the two clamping rings 705 are fixedly connected with a balancing slide bar 14, which is composed of two slide bars and a cylinder. It can realize the synchronous lifting and lowering of the two clamping rings 705 and will not be interfered by the horizontal displacement during clamping. The two balancing slide bars 14 are slidably connected by the cylinder. Two groups of two balancing slide bars 14 and cylinders are provided, which are symmetrically arranged on one side of the two clamping rings 705.

[0041] like Figure 7 and 8 As shown, the flip assembly 9 includes a follower rod 901 fixedly connected to one side of the plasma arc welding device 13, one end of the follower rod 901 is fixedly connected to a rectangular frame 902, the inner wall of the rectangular frame 902 is fixedly connected to a plurality of compression springs 910, four compression springs 910 are provided, and the tooth plate 909 can be avoided, and one end of the plurality of compression springs 910 away from the inner wall of the rectangular plate is fixedly connected to the same tooth plate 909, and the surface of the tooth plate 909 is slidably connected to the inner wall of the rectangular plate.

[0042] An L-shaped plate 904 is fixedly connected to the inner bottom wall of the plate frame 1, and a bearing plate 903 is fixedly connected to the upper surface of the L-shaped plate 904. Two rotating holes are provided on one side of the bearing plate 903, and a rotating shaft 1 905 and a rotating shaft 2 906 are rotatably connected to the inner walls of the two rotating holes respectively. One end of the rotating shaft 1 905 is fixedly connected to one side of the rotating drum 2 10, and a driven gear 908 and a driving gear 907 are fixedly connected to the surfaces of the rotating shaft 1 905 and the rotating shaft 2 906 respectively. The driving gear 907 and the driven gear 908 are meshed with each other, and the teeth of the driving gear 907 and the driven gear 908 are both inclined in design, and the teeth of the tooth plate 909 are also inclined in design, so that when descending, the tooth plate 909 will not drive the rotation of the driving gear 907, thereby realizing the unidirectional rotation of the driving gear 907.

[0043] like Figure 2 and 3 As shown, one side of the plate frame 1 is rotatably connected to a rotating plate 16 via a circular axis, a motor 15 is coaxially installed on one side of the rotating plate 16, the motor 15 is fixedly installed on one side of the plate frame 1, both ends of the rotating plate 16 are rotatably connected to connecting rods 17, and one end of the two connecting rods 17 away from the rotating plate 16 is rotatably connected to one side of the corresponding fixed frame 1 4 and fixed frame 2 5 respectively.

[0044] The specific working method is as follows: when in use, first place the parts to be welded inside the rotating drum 1 701 and the rotating drum 2 10, and start the motor 15 by holding the two parts to be welded. The motor 15 drives the rotation of the rotating plate 16, and the rotation of the rotating plate 16 drives the rotation of the two connecting rods 17, thereby making the fixing frame 1 4 and the fixing frame 2 5 move toward or away from each other. When the fixing frame 1 4 and the fixing frame 2 5 move toward each other, the rotating hoop 6 arranged on the fixing frame 1 4 and the fixing frame 2 5 will drive the rotating drum 1 701 and the rotating drum 2 10 to move toward each other, and the horizontal movement of the rotating drum 1 701 will drive the movement of the U-shaped cylinder 809, and the movement of the U-shaped cylinder 809 will drive the piston 812 arranged inside and the trapezoidal block 1 814 arranged on the top of the piston 812 to follow the movement, and when the trapezoidal block 1 814 contacts the trapezoidal plate 11, it will squeeze the piston 812, and the air inside the U-shaped cylinder 809 will be compressed and will pass through the outlet pipe 804 reaches the inside of the sealing gas cylinder 801, pushing the T-shaped plate 817 to slide inside the sealing gas cylinder 801, thereby driving the sliding of the trapezoidal block 816. Through the sliding of the trapezoidal block 816, the driving rod 802 can be squeezed, so that the driving rod 802 drives the clamping ring 1 705 to move. Through the movement of the clamping ring 1 705, the rotating rod 1 703 and the rotating rod 2 704 are driven to rotate, so that through the action of the cross limit groove 702 and the limit block 707, the other rotating rod 1 703 and the other rotating rod 2 704 can be driven to rotate, so as to realize the synchronous movement of the clamping ring 2 706, so as to realize the clamping of the component. After clamping, by opening the solenoid valve 805 and closing the air flow of the air outlet pipe 804, the air pressure inside the sealing gas cylinder 801 is constant, the drive of the clamping ring 1 705 is kept stable, and the synchronous movement between the clamping ring 1 705 and the clamping ring 2 706 can improve the centering of the component clamping;

[0045] When the clamping ring 1 705 and the clamping ring 2 706 arranged on the rotating drum 1 701 move, the clamping ring 1 705 on the rotating drum 2 10 can be synchronously driven to move by the balancing slide bar 14 when the clamping ring 1 705 on the rotating drum 1 701 moves, so that the parts clamped on the rotating drum 1 701 and the rotating drum 2 10 can be ensured to move synchronously and be on the same horizontal plane during welding and docking, thereby improving the welding effect. The retractable balancing slide bar 14 can avoid being hindered by the clamping movement trajectory. After the clamping is aligned, the cylinder arranged 12 drives the plasma arc welding device 13 to descend to the welding surface of the component to be welded for welding. When the plasma arc welding device 13 descends, it drives the connecting rod to descend synchronously. The descent of the connecting rod can drive the rectangular frame 902 to descend. The descent of the rectangular frame 902 synchronously drives the tooth plate 909 set inside it to descend. When the tooth plate 909 descends, since the tooth teeth direction of the active gear 907 is opposite to that of the tooth teeth of the tooth plate 909, no meshing relationship will be generated during the descent. The compression spring 910 can be set to avoid the tooth plate 909 when the tooth plate 909 descends.

[0046] After welding is completed, the cylinder 12 is retracted, driving the plasma arc welding device 13 to rise. During the rising process, the teeth of the toothed plate 909 and the driving gear 907 face each other, and a meshing relationship occurs, thereby driving the driving gear 907 to rotate during the rising process. The rotation of the driving gear 907 will drive the rotation of the driven gear 908. Through the rotation of the driven gear 908, the rotating drum 10 is turned over, and then the welded parts are turned over. After turning over, the toothed plate 909 returns to the initial position, and then the plasma arc welding is carried out. The device 13 descends again to weld the other side of the component. After welding is completed, the above steps are repeated to flip the component back to the initial clamping state. The motor 15 is used to move the rotating drum 1 701 and the rotating drum 2 10 in opposite directions. When the trapezoidal block 1 814 is not squeezed by the trapezoidal plate 11, the external gas can be drawn into the U-shaped cylinder 809 through the reset of the reset spring 810 to wait for the next welding work. The solenoid valve 805 is disconnected, the air flow refluxes, and the driving rod 802 drives the clamping ring 1 705 to descend, loosening the clamping of the component to achieve unloading.

Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
