Description

Technical Field

[0001] The invention relates to the technical field of shell welding, in particular to shell welding equipment for industrial robot production. Background Art

[0002] Industrial robots are widely used in the industrial field. They can realize various industrial processing and manufacturing functions by relying on their own power and control capabilities. There are many kinds of industrial robots. Putting industrial robots into production lines can increase work efficiency. In some shell production and processing work, industrial robots are needed to complete welding work. In this case, industrial robots are equivalent to a shell welding equipment.

[0003] Generally, when welding the outer shell, in order to increase the welding quality, it is necessary to sprinkle flux along the weld. The flux is generally powder, and then the weld is welded through a welding gun. However, since the flux cannot be guaranteed to be sprinkled on the weld when spreading, some flux will be sprinkled at a farther position of the circumference of the weld. When the welding gun is welding, the flux sprinkled at a farther position next to the weld cannot be used during welding, resulting in a waste of flux. Not only is there a waste, but the reduction in the amount of flux will also reduce the welding quality, making the welding effect worse. Summary of the invention

When the flux is spread along the weld, the turntable can rotate and drive the push rod to slide in the annular groove, so that the push rod can reciprocate left and right.

[0035] A connecting column 10 is fixed to the lower surface of the slide 4, a connecting seat 11 is fixed to the bottom end of the connecting column 10, a first rotating shaft 12 is fixed to both sides of the connecting seat 11, a turntable 13 is rotatably connected to the end of the first rotating shaft 12, a gear ring 14 is fixed to the outer surface of the turntable 13, a gear plate 15 meshing with the gear ring 14 is fixed to the lower surface of the lifting plate 3, a first sliding groove 16 is provided on the lower surface of the connecting seat 11, a sliding rod 17 is slidably provided in the first sliding groove 16, a collecting plate 18 is provided at the bottom of the sliding rod 17, and the collecting plate 18 is rotated by the gear 41 to reciprocate left and right;

[0036] An annular groove 19 is formed on the outer surface of the rotating disk 13, a push rod 20 is slidably disposed in the annular groove 19, the other end of the push rod 20 passes through the connecting seat 11 and is connected to the slide rod 17, a wave-shaped groove 21 is formed on the inner wall of the annular groove 19, a first sliding protrusion 22 is fixed to the end of the slide rod 17, and the first sliding protrusion 22 is slidably disposed in the wave-shaped groove 21;

[0037] The wave-shaped groove 21 includes a first inclined portion 211 and a second inclined portion 212 which are connected in sequence;

[0038] Two sets of side plates 42 are symmetrically welded on the upper surface of the fixed base 2, and electric push rods 43 are installed on the two sets of side plates 42. The output end of the electric push rod 43 is fixed with a clamping plate 44 for fixing the shell 1 to be processed;

[0039] A pad 45 is fixed on the fixed base 2, and a first servo electric cylinder 46 is fixed on the pad 45. The output end of the first servo electric cylinder 46 is fixedly connected to the lower surface of the lifting plate 3. A slide rail 47 is fixed to the upper surface of the lifting plate 3. The slide seat 4 is slidably set on the slide rail 47. A second servo electric cylinder 48 is installed at the end of the lifting plate 3, and the output end of the second servo electric cylinder 48 is fixedly connected to the surface of the slide seat 4.

[0040] In the present technical solution, when performing shell welding, the shell 1 to be processed is first placed on the fixed base 2, and then the clamping plate 44 is pushed to move by the electric push rod 43, so that the clamping plate 44 fixes the shell 1 to be processed in a suitable position, so that the weld of the shell 1 to be processed is located below the welding gun 8, and then the height of the lifting plate 3 is adjusted by the first servo electric cylinder 46, so that the collecting plate 18 contacts the upper surface of the shell 1 to be processed. At this time, the port of the feeding pipe 6 is located on one side of the shell 1 to be processed, and then the slide 4 is pushed to slide on the slide rail 47 by the second servo electric cylinder 48, and the slide 4 drives the barrel 5, The feed tube 6 and the welding gun 8 move along the weld of the shell 1 to be processed. When the slide 4 moves, the valve 7 is first opened to sprinkle the flux inside the barrel 5 around the weld of the shell 1 to be processed through the feed tube 6, and then the welding gun 8 performs welding work at the back, so as to facilitate the welding work after sprinkling the flux on the weld of the shell 1 to be processed, thereby increasing the welding effect. After the feed tube 6 moves out of the weld of the shell 1 to be processed, the valve 7 is closed to stop feeding, and the slide 4 continues to move until the welding gun 8 completes the welding work of the weld, and then the device is reset to remove the shell 1 to be processed.

[0041] When applying flux, Figure 1 and Figure 3 As shown, the connecting column 10 moves to the right along with the sliding seat 4, the connecting column 10 drives the connecting seat 11 to move to the right, and the connecting seat 11 drives the collecting plate 18 to move to the right. The setting of the collecting plate 18 can limit the range of flux spreading, so that the scattered flux is between the two sets of collecting plates 18. When the connecting seat 11 moves to the right, it drives the turntable 13 to move to the right. Due to the engagement of the gear ring 14 and the tooth plate 15, the gear ring 14 moves on the tooth plate 15, so that the turntable 13 rotates around the first rotating shaft 12. The rotation of the turntable 13 causes the end of the push rod 20 to slide inside the annular groove 19, and the push rod 20 slides inside the annular groove 19, driving the first sliding protrusion 22 to slide inside the wavy groove 21, as shown in FIG. Figure 5 As shown, the push rod 20 performs a left-right reciprocating motion, the push rod 20 performs a left-right reciprocating motion, drives the slide bar 17 to reciprocate left-right in the first slide groove 16, and the slide bar 17 drives the collection plate 18 to reciprocate left-right (as shown in FIG. Figure 6 As shown), the collecting plate 18 can centrally process the flux sprinkled on the shell 1 to be processed, which is convenient for concentrating the flux on the weld, avoiding the waste of flux, and is conducive to improving the welding quality.

[0042] In this technical solution, the welding equipment is controlled by two computers and adopts the international mainstream Ethercat bus controller; the servo electric cylinder part adopts servo drive technology and the international mainstream Ethercat bus communication method, with fast transmission speed and strong reliability; the wires use high-flexible cables, and the grease, synchronous belt, air switch, contactor and other accessories are imported.

[0043] In the second embodiment, after the collecting plate 18 concentrates the flux inward, the collecting plate 18 needs to move outward. Since the collecting plate 18 is arranged vertically, when the two sets of collecting plates 18 move outward, a certain suction force will be generated between the two sets of collecting plates 18. Although the collecting plate 18 has concentrated the flux at the weld, due to the existence of the suction force, when the collecting plate 18 moves to the side away from the weld, a part of the flux may be moved, so that part of the flux is dispersed, resulting in a waste of the flux. This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figure 1-Figure 12 The surface of the slide bar 17 is provided with a second slide groove 23 for the push rod 20 to slide, and a limiting groove 24 is provided on the side wall of the second slide groove 23. A limiting column 25 is fixed on the outer surface of the push rod 20, and the limiting column 25 is slidably set in the limiting groove 24. Track grooves 26 are provided on both side walls of the first slide groove 16. Second sliding protrusions 27 are symmetrically fixed on the outer surface of the slide bar 17, and the second sliding protrusions 27 are slidably set in the track grooves 26;

[0044] The track groove 26 includes a first horizontal portion 261, an ascending portion 262, a second horizontal portion 263 and a descending portion 264 which are sequentially connected and arranged;

[0045] A first rotating plate 265 is elastically provided at a connection between the first horizontal portion 261 and the ascending portion 262 , and a second rotating plate 266 is elastically provided at a connection between the first horizontal portion 261 and the descending portion 264 .

[0046] In this technical solution, if Figure 8 As shown, the first rotating plate 265 and the second rotating plate 266 are both rotatably connected to the inside of the connecting seat 11 through a pin shaft, and a torsion spring is provided on the pin shaft, so that the first rotating plate 265 and the second rotating plate 266 are elastically arranged in the track groove 26, and the first rotating plate 265 can only be pressed Figure 8 The second rotating plate 266 can only be rotated upward in the state of Figure 8 The state in the middle rotates downwards and cannot rotate upwards;

[0047] When the collecting plate 18 performs left and right reciprocating motion, Figure 4 and Figure 5 As shown, Figure 4 The right side of the collecting plate 18 is used as an example for explanation, and the movement direction of the left collecting plate 18 is opposite to that of the right collecting plate 18. First, when the push rod 20 drives the first sliding protrusion 22 to slide along the first inclined portion 211 of the wave-shaped groove 21, the push rod 20 moves to the left, and the push rod 20 moves to the left to push the slide bar 17 to slide in the first slide groove 16, and the slide bar 17 drives the second sliding protrusion 27 to slide along the first horizontal portion 261 of the track groove 26 from right to left (such as Figure 8As shown in the figure), the collecting plate 18 moves to the left. When the second sliding protrusion 27 slides to the first rotating plate 265 on one side of the first horizontal portion 261, the second sliding protrusion 27 contacts the first rotating plate 265, causing the first rotating plate 265 to rotate upward until the second sliding protrusion 27 slides to the leftmost end of the first horizontal portion 261. Since the connection between the first rotating plate 265, the first horizontal portion 261 and the rising portion 262 is elastically arranged, after the first rotating plate 265 loses the contact of the second sliding protrusion 27, it can be reset to the state shown in Figure 8 again. At this time, the collecting plate 18 completes the centralized processing of the solder flux.

[0048] Then the collecting plate 18 starts to reset to the right, at which time the second sliding protrusion 27 slides along the second inclined portion 212, so that the second sliding protrusion 27 drives the push rod 20 to move to the right, and the push rod 20 drives the slide bar 17 to move to the right in the first slide groove 16, and the slide bar 17 drives the collecting plate 18 to reset to the right. When the slide bar 17 moves to the right in the first slide groove 16, due to the resistance of the first rotating plate 265, the second sliding protrusion 27 can only slide along the rising portion 262, so that the slide bar 17 moves to the right and moves upward at the same time, so that the slide bar 17 drives the collecting plate 18 to move upward when it moves upward, and lifts the collecting plate 18 upward, and then the second The sliding protrusion 27 slides along the second horizontal portion 263, so that the collecting plate 18 continues to move rightward. When the second sliding protrusion 27 slides along the descending portion 264, the sliding rod 17 moves rightward and downward at the same time, so that the sliding rod 17 drives the collecting plate 18 to move downward when moving downward. When the second sliding protrusion 27 slides to the second rotating plate 266, it contacts the second rotating plate 266, so that the second rotating plate 266 rotates downward until the second sliding protrusion 27 slides to the initial position again. The second rotating plate 266 loses the contact of the second sliding protrusion 27 and can be reset to the state shown in Figure 8 again. At this time, the collecting plate 18 also completes the rightward reset movement.

[0049] Through the above process, the collecting plate 18 can move upward while moving toward the outside of the weld, so that the collecting plate 18 is not in the same horizontal plane with the flux when moving outward, thereby reducing the suction force generated by the collecting plate 18 on the flux, and effectively preventing part of the flux from being dispersed again when the collecting plate 18 moves outward.

[0050] In the present technical solution, by setting the second slide groove 23, when the slide rod 17 moves upward, the push rod 20 can slide relative to the slide rod 17, and by setting the limit groove 24 and the limit column 25, the push rod 20 can be prevented from sliding out of the slide rod 17, so that the push rod 20 can drive the slide rod 17 to move left and right.

[0051] In the third embodiment, when the collecting plate 18 is lifted upward, although the suction force on the soldering flux can be reduced, since the bottom of the collecting plate 18 moves upward and outward at the same time, a small amount of suction force may be generated on the soldering flux, thereby causing the soldering flux to be scattered. To address this problem, this embodiment is an improvement made on the basis of the second embodiment. For details, please refer to Figure 1-Figure 12 A hinge seat 28 is fixed at the bottom end of the slide bar 17, a second rotating shaft 29 is rotatably provided on the hinge seat 28, a straight plate 30 is fixed on the circumference of the second rotating shaft 29, and the end of the straight plate 30 is fixedly connected to the collecting plate 18, and the slide bar 17 drives the collecting plate 18 to deflect by lifting;

[0052] A first hydraulic oil groove 31 is provided inside the slide rod 17, and a first piston plate 32 is slidably provided inside the first hydraulic oil groove 31. An adjusting column 33 is fixed to the lower surface of the push rod 20, and the bottom end of the adjusting column 33 is fixedly connected to the first piston plate 32. A transmission block 34 is fixed to the upper surface of the hinge seat 28, and a second hydraulic oil groove 35 is provided inside the transmission block 34. An oil delivery pipe 36 is provided between the first hydraulic oil groove 31 and the second hydraulic oil groove 35. A second piston plate 37 is elastically provided inside the second hydraulic oil groove 35, a transmission rod 38 is fixed to the lower surface of the second piston plate 37, and a rack 39 is fixed to the bottom end of the transmission rod 38. A rotating groove 40 is provided inside the hinge seat 28, and a gear 41 fixedly connected to the second rotating shaft 29 is rotatably provided in the rotating groove 40, and the gear 41 meshes with the rack 39.

[0053] In the technical solution, when the second sliding protrusion 27 slides on the rising portion 262, the second sliding protrusion 27 drives the sliding rod 17 to move upward, and the sliding rod 17 moves upward (such as Fig. 9 and Fig.10 As shown in the figure, the push rod 20 slides downward in the second slide groove 23, the push rod 20 slides downward to drive the adjustment column 33 to move downward, the adjustment column 33 drives the first piston plate 32 to move downward, the first piston plate 32 moves downward, and the hydraulic oil in the first hydraulic oil groove 31 is pressed into the second hydraulic oil groove 35 through the oil delivery pipe 36 (as shown in the figure). Fig.11As shown in the figure, at this time, the hydraulic oil in the second hydraulic oil groove 35 increases, so that the second piston plate 37 moves downward, and the second piston plate 37 drives the transmission rod 38 to move downward. A spring 49 is sleeved on the outer side of the transmission rod 38, and the two ends of the spring 49 are respectively fixed on the lower surface of the second piston plate 37 and the inner wall of the transmission block 34. When the transmission rod 38 moves downward, the spring 49 is compressed to store force in the spring 49, and then the transmission rod 38 drives the rack 39 to move downward, the rack 39 drives the gear 41 to rotate, the gear 41 drives the second rotating shaft 29 to rotate, the second rotating shaft 29 drives the straight plate 30 to rotate, and the straight plate 30 drives the collecting plate 18 to rotate, so that the collecting plate 18 can rotate while moving upward, so that the two groups of collecting plates 18 can rotate into an inverted eight-shaped shape to perform a reset movement. The collecting plate 18 in the inverted eight-shaped shape can reduce the suction force generated between the two groups of collecting plates 18 during the reset movement of the collecting plate 18, further reducing the possibility of the flux being dispersed. At the same time, the collecting plate 18 in the inverted eight-shaped shape can also play a certain role in guiding materials. When the material discharge pipe 6 is discharging materials, it is convenient for the flux to slide downward along the collecting plate 18 in the inverted eight-shaped shape, which is convenient for the concentration of the flux.

[0054] When the second sliding protrusion 27 slides in the descending portion 264, the sliding rod 17 moves downward, causing the push rod 20 to slide upward in the second sliding groove 23, and the push rod 20 slides upward to drive the adjusting column 33 to move upward, and the adjusting column 33 drives the first piston plate 32 to move upward, and the first piston plate 32 moves upward, and the hydraulic oil inside the second hydraulic oil groove 35 is sucked into the first hydraulic oil groove 31 through the oil pipe 36. At this time, the hydraulic oil inside the second hydraulic oil groove 35 is reduced, and the spring 49 releases force, causing the second piston plate 37 to move upward, and the second piston plate 37 drives the transmission rod 38 to move upward, and the transmission rod 38 drives the rack 39 to move upward, and the rack 39 drives the gear 41 to rotate, and the gear 41 drives the second rotating shaft 29 to rotate, and the second rotating shaft 29 drives the straight plate 30 to rotate, and the straight plate 30 drives the collecting plate 18 to rotate, so that the collecting plate 18 is reset.
