Description

Technical Field

[0001] The present invention relates to the technical field of bucket welding production, and specifically relates to an excavator bucket welding device. Background Art

[0002] The bucket of an excavator is an important component of the excavator. The quality of the bucket directly affects the service life of the excavator. Due to the large size and weight of the excavator bucket, in the production process, assembly and welding are both difficult. The existing bucket production process generally adopts the methods of manual assembly and manual welding.

[0003] Generally, when welding the bucket, it is necessary to assemble the arc-shaped bottom plate of the bucket with two groups of side plates, and then manually carry out the welding operation. During this period, due to the influence of the assembly quality of the side plates and the processing quality of the side plates, the two groups of side plates often cannot ensure that the distances between the corresponding points are equal, resulting in some positions of the side plates being far from or overly entering the bottom plate. At this time, usually, personnel manually knock the side plates, and after correcting the side plates, a group of rod bodies are temporarily welded to ensure that when welding the side plates and the bottom plate, the shape of the side plates maintains the state after being knocked and repaired. However, this method completely relies on manual measurement and correction, which is time-consuming and laborious. Summary of the Invention

[0030] A support clamping structure 2 connected to the base 1;

[0031] Two groups of side welding structures 3 connected to the base 1. The two groups of side welding structures 3 include first robotic arms 4 arranged on both sides of the support clamping structure 2. The first robotic arms 4 are connected to the base 1, and a welding torch 5 is fixedly connected to the moving end of the first robotic arms 4;

[0032] A spacing correction structure 6 connected to the base 1, the spacing correction structure 6 includes a second robotic arm 7 connected to the base 1, a connecting seat 8 is installed on the second robotic arm 7, the connecting seat 8 is connected with a touch pressure ranging mechanism 9, the connecting seat 8 is connected with a distance adjusting mechanism 10, the distance adjusting mechanism 10 includes a telescopic bonding part 11 connected to the connecting seat 8, and the telescopic bonding part 11 adjusts the relative distance of the bonded parts on the two bucket side plates by bonding the bucket side plates and adjusting the length, and the connecting seat 8 is connected with a cutting part 12, and the cutting part 12 is used for cutting off the telescopic bonding part 11 adhesively attached to the bucket side plates.

[0033] Place the bottom plate of the bucket on the support clamping structure 2, and use the support clamping structure 2 to clamp the two side plates to be welded, so that the side plates are spliced with the bottom plate. Then, the second robotic arm 7 moves the connecting seat 8, so that the touch pressure ranging mechanism 9 measures the spacing of each position of the two side plates. When the distance between the two side plates exceeds the preset value, the telescopic bonding part 11 bonds the measured part of the side plate, and then the telescopic bonding part 11 automatically expands and contracts to pull or push the side plate to adjust the shape of the side plate. Then, the first robotic arm 4 moves the welding torch 5, and the welding torch 5 welds the adjusted side plate and the bent bottom plate together to complete the welding of the basic structure of the bucket. Through the mutual cooperation of the support clamping structure 2, the side welding structure 3, and the spacing correction structure 6, the present invention fixes and welds the bottom plate and side plates constituting the bucket, and uses the spacing correction structure 6 to perform a pulling and adjusting operation on the positions where the side plate spacing does not meet the standard, so that the side plate is adjusted in shape under the push and pull of the spacing correction structure 6, which is convenient for performing a labor-saving shape adjustment operation on the side plate before welding, and welding the bucket faster and more labor-saving.

[0034] In one case of this embodiment, the support clamping structure 2 includes a support table 13 fixedly connected to the base 1, a first electromagnet 14 is fixedly installed in the support table 13, the base 1 is fixedly connected with a transverse movement track 15, two first motors 16 are fixedly installed on the transverse movement track 15, the output end of the first motor 16 is fixedly connected with a lead screw 17, the lead screw 17 is threadedly connected with a sliding arm 18 slidably connected to the transverse movement track 15, and the sliding arm 18 is fixedly connected with a pneumatic gripper 19. The pneumatic gripper 19 is used for actively clamping the side plates of the bucket, and the first electromagnet 14 is used for magnetically attracting the bottom plate of the bucket placed on the support table 13. After the pneumatic gripper 19 clamps the side plates of the bucket, the first motor 16 drives the lead screw 17 to rotate, and the rotating lead screw 17 drives the sliding arm 18 to move along the transverse movement track 15, and the moving sliding arm 18 moves the pneumatic gripper 19 to move the side plate and adjust the position of the side plate.

[0035] In a case of this embodiment, the touch pressure ranging mechanism 9 includes a double-output shaft motor 20 fixedly connected to the connecting seat 8. The output end of the double-output shaft motor 20 is fixedly connected with a rotating arm 21. The rotating arm 21 is fixedly connected with two groups of symmetrically arranged rectangular sleeves 22. A fixed grating 23 is fixedly installed in the rectangular sleeve 22. A sliding strip 24 is slidably connected to the rectangular sleeve 22. The sliding strip 24 is fixedly connected with a moving grating 25 adapted to the fixed grating 23. The sliding strip 24 is fixedly connected with a pressure sensor 26. The pressure sensor 26 is fixedly connected with a threaded sleeve 27. The threaded sleeve 27 is threadedly connected with a ball head abutting block 28. The rectangular sleeve 22 is fixedly connected with a rod seat 29. The rod seat 29 is fixedly connected with a first active telescopic rod 30. The moving end of the first active telescopic rod 30 is fixedly connected with the sliding strip 24. During use, the first active telescopic rod 30 drives the sliding strip 24 to move. As the ball head abutting block 28 abuts against the side plate of the bucket, the threaded sleeve 27 squeezes the pressure sensor 26. At this time, the first active telescopic rod 30 stops telescoping. The moving sliding strip 24 drives the moving grating 25 to move relative to the fixed grating 23. As the moving grating 25 moves relative to the fixed grating 23, the controller obtains the capacitance change value between the moving grating 25 and the fixed grating 23 to measure the moving distance of the moving grating 25 and the sliding strip 24, and further measures the distance between the measured points on the side plate of the bucket.

[0036] In one case of this embodiment, the telescopic bonding part 11 includes a power supply and communication socket 31 fixedly connected to the connection base 8. The power supply and communication socket 31 is movably connected to a power supply and communication plug 32. The power supply and communication socket 31 is connected to an electromagnetic pin connection component 33, and the electromagnetic pin connection component 33 is connected to the power supply and communication plug 32. The power supply and communication plug 32 is fixedly connected to an intermediate frame 34. The intermediate frame 34 is fixedly connected to two groups of first electric telescopic rods 35. The moving end of each group of first electric telescopic rods 35 is fixedly connected to an outer cylinder shell 36. The intermediate frame 34 is fixedly connected to two groups of driven telescopic frames. The moving end of the driven telescopic frame is fixedly connected to the outer cylinder shell 36. The outer cylinder shell 36 is fixedly connected to heat dissipation fins 37. A glue storage shell 38 is fixedly installed inside the outer cylinder shell 36. A plurality of second electric telescopic rods 39 are fixedly installed inside the glue storage shell 38. The moving ends of the plurality of second electric telescopic rods 39 are commonly fixedly connected to a push plate 40 slidably installed inside the glue storage shell 38. On one side of the push plate 40 away from the second electric telescopic rods 39, there is a hot melt adhesive layer 41. The hot melt adhesive layer 41 is arranged inside the glue storage shell 38. The hot melt adhesive layer 41 wraps a heating rod 44. The heating rod 44 is slidably connected to the push plate 40. The heating rod 44 is fixedly connected to the glue storage shell 38. An elastic gasket 42 is bonded to the open end of the outer cylinder shell 36. A cavity is provided between the outer cylinder shell 36 and the glue storage shell 38. The heating rod 44, the second electric telescopic rods 39, and the first electric telescopic rods 35 are all electrically connected to the power supply and communication plug 32. After the power supply and communication plug 32 and the power supply and communication socket 31 are mutually docked, the electromagnetic pin connection component 33 is inserted into the power supply and communication plug 32 to restrict the movement of the power supply and communication plug 32, and thus restrict the movement of the intermediate frame 34. The power supply and communication socket 31 and the power supply and communication plug 32 perform information interaction operations and electrical connections. The first electric telescopic rods 35 drive the outer cylinder shell 36 to move, and the moving outer cylinder shell 36 drives the glue storage shell 38 to move, so that the elastic gasket 42 abuts against the side plate. Then the heating rod 44 heats up, and the hot melt adhesive layer 41 is heated and melted and flows towards the side plate and the outer cylinder shell 36. And the second electric telescopic rods 39 push the push plate 40 to push the liquid hot melt adhesive away from the glue storage shell 38. As the heating rod 44 stops heating up and the heat dissipation fins 37 dissipate heat, the hot melt adhesive cools and solidifies. At this time, the first electric telescopic rods 35 pull the outer cylinder shell 36, and the outer cylinder shell 36 pulls the side plate through the re-cooled hot melt adhesive. If the first electric telescopic rods 35 extend, the outer cylinder shell 36 pushes the elastic gasket 42, and the elastic gasket 42 presses the side plate to adjust the shape of the side plate, and thus adjust the distance between the two side plates. After the electromagnetic pin connection component 33 and the power supply and communication plug 32 are mutually separated, by pulling the intermediate frame 34, the power supply and communication plug 32 and the power supply and communication socket 31 are mutually separated.

[0037] In one case of this embodiment, the outer cylinder shell 36 is fixedly connected with an exhaust pipe 43. By providing the exhaust pipe 43, it is convenient to discharge the air in the outer cylinder shell 36, and thus it is convenient to push the liquid hot melt adhesive.

[0038] In one case of this embodiment, the electromagnetic pin-connection component 33 includes a guide sleeve 45 fixedly connected with the power supply and communication socket 31. A second electromagnet 46 is fixedly installed in the guide sleeve 45. The second electromagnet 46 is fixedly connected with a spring, and the spring is fixedly connected with a plug pin 47 slidably installed in the guide sleeve 45. The plug pin 47 has ferromagnetism, and the plug pin 47 is movably connected with the power supply and communication plug 32. Under the magnetic attraction of the second electromagnet 46 on the plug pin 47, the plug pin 47 is magnetically drawn into the guide sleeve 45, so that the plug pin 47 is separated from the power supply and communication plug 32, and the limit of the electromagnetic pin-connection component 33 on the power supply and communication plug 32 is released.

[0039] Embodiment 2, on the basis of Embodiment 1, refer to Figures 1 to 4 , the cutting part 12 includes two groups of second active telescopic rods 48 fixedly connected with the connecting seat 8. The moving end of the second active telescopic rod 48 is fixedly connected with a seat body 50. The seat body 50 is fixedly connected with a dovetail bar 49 slidably connected with the connecting seat 8. The seat body 50 is hinged with a transmission box 51. Two groups of belt pulleys 52 are rotatably installed in the transmission box 51. One group of belt pulleys 52 is coaxially fixedly connected with a saw blade 53. The transmission box 51 is fixedly connected with a second motor 54. The output shaft of the second motor 54 is coaxially fixedly connected with the other group of belt pulleys 52. The two groups of belt pulleys 52 are jointly connected with a transmission belt 55. The seat body 50 is hinged with a third active telescopic rod 56, and the third active telescopic rod 56 is hinged with the transmission box 51. The second motor 54 drives one group of belt pulleys 52 to rotate, so that the belt pulleys 52 drive the transmission belt 55 to move, the transmission belt 55 drives the other group of belt pulleys 52 to rotate, and the other group of belt pulleys 52 drives the saw blade 53 to rotate. At this time, the second active telescopic rod 48 drives the seat body 50 to move, the seat body 50 drives the transmission box 51 to move, and as the third active telescopic rod 56 pushes the transmission box 51 to rotate, the saw blade 53 cuts the elastic gasket 42 and the re-cooled hot melt adhesive, so as to facilitate the separation of the side plate from the telescopic bonding part 11.
