Description

Technical Field

[0001] The invention relates to the technical field of swing welding, in particular to a welding tool for building a children's playground. Background Art

[0002] Petal-shaped swings in children's parks are both beautiful and fun. Their seats are designed in the shape of lovely petals, with vibrant colors and lively shapes that effectively capture children's interest. Some petal-shaped swings even feature a slight rotation function, further enhancing the fun of play.

[0003] The petal-shaped swing's steel frame utilizes a specialized welding process. Its shape consists of a petal-shaped base interlaced with multiple sets of horizontal and vertical curved rods. However, existing welding tooling is difficult to adapt to this complex, three-dimensional, interlaced welding process. Manual positioning and fixing are often required, but manual fixing methods are unstable and can easily affect the accuracy of subsequent welding.

[0004] In addition, the metal dust generated during the welding process will be suspended in the air and adhere to the surface of the steel, thereby reducing the stability of the subsequent welding tooling. At the same time, due to the strong thermal conductivity of steel, if the welded parts are not cooled in time, workers may accidentally touch the high-temperature parts during subsequent operations, which is very likely to cause burns.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1-9 The welding tool shown is for use in constructing a children's playground, comprising a workbench 1, a processing table 2 movably disposed in the middle of the upper surface of the workbench 1, a petal-shaped base 3 placed on the upper surface of the processing table 2, a plurality of transverse arc-shaped rods 4 and a plurality of longitudinal arc-shaped rods 5 arranged alternately on the upper side of the petal-shaped base 3, and a rotation guide mechanism disposed on the upper surface of the workbench 1 and located outside the petal-shaped base 3, the plurality of transverse arc-shaped rods 4, and the plurality of longitudinal arc-shaped rods 5.

[0033] The rotating guide mechanism includes an arc-shaped guide tube 6, a guide pipe 7 is fixedly embedded at the inner lower part of the arc-shaped guide tube 6, and a plurality of air outlet holes 8 are opened at the inner lower part of the guide pipe 7. The guide pipe 7 can clean or cool the petal-shaped base 3, the horizontal arc-shaped rod 4 and the longitudinal arc-shaped rod 5 below through the air outlet holes 8;

[0034] An adjustable fixing mechanism is provided for sliding movement on the outer sides of the arc-shaped conduit 6 and the guide tube 7. The adjustable fixing mechanism includes a rotating seat 9. Two rotating shafts 10 are rotatably installed on the left and right ends of the inner side of the rotating seat 9. The outer surfaces of the two rotating shafts 10 are respectively fixed with rotating frames 11. An extension plate 12 is slidably inserted on the inner side of the rotating frame 11. The left and right ends of the two extension plates 12 are respectively provided with fixing hooks 13 that can be adjusted at multiple angles. The rotating guiding mechanism cooperates with the adjustable fixing mechanism to assist the petal-shaped base 3 to be welded and assembled with multiple transverse arc rods 4 and multiple longitudinal arc rods 5 respectively.

[0035] like Figure 1-Figure 7 As shown, the rotating guide mechanism also includes two mounting seats 14, the left and right bottom ends of the arc-shaped guide tube 6 and the guide tube 7 are fixedly connected to the upper ends of the two mounting seats 14, the left side of the left mounting seat 14 is fixedly connected to a rotating rod 16, and the right side of the right mounting seat 14 is fixedly connected to a rotating tube 18. The upper surface of the workbench 1 and near the left and right ends are respectively fixedly installed with connecting seats 17. The outer side of the rotating rod 16 is rotatably connected to the inner side of the left connecting seat 17. The left end of the rotating rod 16 is fixedly connected to the output shaft of the first motor 20. The first motor 20 It is fixedly installed on the upper surface of the workbench 1 through a connecting piece, the right end of the rotating tube 18 is rotatably connected to the assembly seat 19, the outer side of the assembly seat 19 is fixedly connected to the inside of the right connecting seat 17, the right end of the assembly seat 19 is fixedly connected to a T-shaped guide tube 21, and an electrically controlled three-way ball valve 22 is provided inside the T-shaped guide tube 21, and the guide tube 7, the right mounting seat 14, the rotating tube 18 and the assembly seat 19 are all provided with a diversion cavity, the front and rear sides of the arc-shaped guide tube 6 are provided with sliding grooves, and the upper side of the arc-shaped guide tube 6 is provided with multiple fixing holes 23.

[0036] The front and rear ends of the T-shaped guide tube 21 are connected to the cooling pipe and the dust suction pipe respectively. During the welding operation, the rotating guide mechanism is interspersed to perform auxiliary processing. Whether it is the transverse arc rod 4 or the longitudinal arc rod 5, before welding, it is necessary to start the first motor 20 to adjust the position of the guide tube 7, and then switch the electronically controlled three-way ball valve 22 to the dust suction mode, so that the air flow passes through the guide cavity in the T-shaped guide tube 21, the assembly seat 19 and the rotating tube 18, and finally sucks out the dust on the welding surface of the lower transverse arc rod 4 or the longitudinal arc rod 5 from the air outlet 8 of the guide tube 7, thereby achieving the operation of first dust suction and then fixing, avoiding the subsequent stability of the transverse arc rod 4 or the longitudinal arc rod 5 fixed by the effective fixing hook 13 due to dust. After each transverse arc rod 4 or longitudinal arc rod 5 is welded, the position of the guide tube 7 is adjusted again and switched to the cooling mode, so that the cooling air flow passes through the air outlet 8 of the guide tube 7 to quickly cool down the welding part below, preventing the operator from contacting the high-temperature part and causing burns.

[0037] like Figures 1-8 As shown, the adjustable fixing mechanism also includes a movable seat 24, and the middle part of the inner side of the movable seat 24 slides with the outer side of the arc-shaped catheter 6 and the guide tube 7. The inner side of the movable seat 24 is provided with a sliding block 25 that slides with the sliding groove of the arc-shaped catheter 6. Two insertion rods 26 are movably inserted on the upper side of the movable seat 24, and the bottom ends of the insertion rods 26 can pass through the corresponding fixing holes 23 and be inserted into the fixing grooves opened on the upper surface of the sliding block 25. The upper ends of the two insertion rods 26 are fixedly installed with a pulling member 15, and the outer surface of the left insertion rod 26 is provided with a spring 27. The upper and lower ends of the spring 27 are respectively fixed to the pulling member 15 and the corresponding positions on the inner side of the movable seat 24. Place the longitudinal arc rod 5 on the outside of the welded transverse arc rod 4, pull the pulling piece 15 upward to disengage the insertion rod 26 from the fixing hole 23, slide it along the arc guide tube 6 to a suitable position above the longitudinal arc rod 5, release the pulling piece 15, and the spring 27 arranged below it will generate an elastic restoring force, pushing the insertion rod 26 to be reinserted into the fixing hole 23 at the corresponding position, thereby achieving fast and accurate positioning.

[0038] A plurality of second guide rods 39 and a second telescopic cylinder 40 are fixedly mounted in the middle of the workbench 1. The lower surface of the processing table 2 is fixedly connected to the telescopic ends of the second telescopic cylinder 40 and the movable ends of the plurality of second guide rods 39. The second telescopic cylinder 40 is positioned in the middle of the processing table 2. The plurality of second guide rods 39 are arranged in a circular array centered on the second telescopic cylinder 40. A plurality of fixed legs are fixedly mounted on the lower surface of the workbench 1. Activating the second telescopic cylinder 40 drives the processing table 2, the petal-shaped base 3, and the transverse curved rod 4 to rise and fall as a whole, adjusting the distance between the upper surface of the transverse curved rod 4 and the curved guide 6 to maintain an appropriate distance. The first motor 20 is then activated, rotating the curved guide 6 and its adjustable fixing mechanism to directly above the transverse curved rod 4. Based on the actual length of the transverse curved rod 4, the two third motors 31 and the two first telescopic cylinders 32 are simultaneously activated to adjust the two side extension plates 12 to the appropriate fixed position above the transverse curved rod 4.

[0039] A second motor 28 is fixedly mounted on the rear side of the movable base 24. Two linkage shafts 29 are rotatably mounted on the front and rear sides of the base 24. The output shaft of the second motor 28 is fixedly connected to the upper end of the rear linkage shaft 29. The outer surfaces of the two linkage shafts 29 are each fixedly fitted with meshing gears 30. The bottom end of the front linkage shaft 29 is fixedly connected to the upper end surface of the rotating base 9. The front ends of the two rotating shafts 10 are respectively fixedly connected to third motors 31. The bottoms of the third motors 31 are fixedly mounted on the front side of the rotating base 9 via connectors. A first telescopic cylinder 32 and a first guide rod 33 are fixedly mounted on the inner side of the rotating frame 11. The telescopic end of the first telescopic cylinder 32 and the movable end of the first guide rod 33 are fixedly connected to the oblique upper end of the extension plate 12. After the transverse curved rod 4 is welded, the second motor 28 is activated to rotate the rear linkage shaft 29 90 degrees counterclockwise. The meshing gears 30 drive the synchronous rotation of the front linkage shaft 29, thereby adjusting the fixing mechanism below the rotating base 9 to the operating angle suitable for the longitudinal curved rod 5.

[0040] The bottom end of the extension plate 12 is rotatably installed with a first adjusting shaft 34, and an adjusting piece 35 is fixedly mounted in the middle of the outer surface of the first adjusting shaft 34. The front end of the first adjusting shaft 34 is fitted with a first nut 36 with a threaded fit, and the front end of the adjusting piece 35 is rotatably installed with a second adjusting shaft 37. The oblique upper end of the second adjusting shaft 37 is fixedly installed and connected to the upper end of the fixed hook 13, and a friction pad is provided on the inner side of the fixed hook 13. The oblique lower end of the second adjusting shaft 37 is fitted with a second nut 38 with a threaded fit. Resistance bushings are provided at the connection between the first adjusting shaft 34 and the extension plate 12 and at the rotation connection between the second adjusting shaft 37 and the adjusting piece 35. The setting of the resistance bushing makes it possible for friction resistance to exist between the first adjusting shaft 34 and the second adjusting shaft 37 during the rotation process, thereby facilitating the subsequent locking operation of the fixed hook 13. The operator rotates the adjusting piece 35 and the fixing hook 13 respectively so that the two fixing hooks 13 firmly hook the transverse arc rod 4, and then tightens the first nut 36 and the second nut 38 on the first adjusting shaft 34 and the second adjusting shaft 37. Finally, the operator uses a welding gun to weld the two ends of the transverse arc rod 4 to the petal-shaped base 3.

[0041] During use, first place the petal-shaped base 3 steadily on the processing table 2. Then, pick up the transverse curved rod 4 and precisely align its left and right ends with the corresponding welding positions on the petal-shaped base 3 (weld the middle transverse curved rod 4 first to determine the appropriate distance between the curved conduit 6 and the transverse curved rod 4). Activate the second telescopic cylinder 40, which drives the processing table 2, petal-shaped base 3, and transverse curved rod 4 to move upward and downward as a whole, adjusting the distance between the upper surface of the transverse curved rod 4 and the curved conduit 6 to maintain the appropriate distance. Then start the first motor 20 to rotate the arc-shaped guide tube 6 and its adjustable fixing mechanism to the top of the transverse arc rod 4. According to the actual length of the transverse arc rod 4, start the two third motors 31 and the two first telescopic cylinders 32 synchronously, and adjust the extension plates 12 on both sides to the appropriate fixed position above the transverse arc rod 4. The operator then rotates the adjusting piece 35 and the fixing hook 13 respectively so that the two fixing hooks 13 firmly hook the transverse arc rod 4, and then tightens the first nut 36 and the second nut 38 on the first adjusting shaft 34 and the second adjusting shaft 37. Finally, use a welding gun to weld the two ends of the transverse arc rod 4 to the petal-shaped base 3. Repeat the above operations to complete the welding of all transverse arc rods 4 in sequence.

[0042] After the welding of the transverse arc rod 4 is completed, the second motor 28 is started to rotate the rear linkage shaft 29 90 degrees counterclockwise, and the front linkage shaft 29 is driven to rotate synchronously by the mutually meshing gears 30, so that the fixing mechanism under the rotating seat 9 is adjusted to a working angle suitable for the longitudinal arc rod 5, and the longitudinal arc rod 5 is placed on the outside of the welded transverse arc rod 4, and the pulling piece 15 is pulled upward to disengage the plug-in rod 26 from the fixing hole 23, and slide along the arc guide tube 6 to the appropriate position above the longitudinal arc rod 5, after releasing the pulling piece 15, the spring 27 arranged under it generates an elastic restoring force, which pushes the plug-in rod 26 to be reinserted into the fixing hole 23 at the corresponding position, so as to achieve fast and accurate positioning. After the positioning of the longitudinal arc rod 5 is completed by referring to the fixing method of the transverse arc rod 4, a welding gun is used to weld it firmly to the transverse arc rod 4 and the petal-shaped base 3, and this process is repeated until the welding of all longitudinal arc rods 5 is completed. This mechanical fixing method effectively avoids the instability of manual operation and significantly improves the welding accuracy.

[0043] In addition, the front and rear ends of the T-shaped guide tube 21 are connected to the cooling pipe and the dust suction pipe respectively. During the welding operation, the rotating guide mechanism is interspersed to provide auxiliary treatment. Whether it is the transverse curved rod 4 or the longitudinal curved rod 5, before welding, it is necessary to first start the first motor 20 to adjust the position of the guide tube 7, and then switch the electronically controlled three-way ball valve 22 to the dust suction mode, so that the air flow passes through the guide cavity in the T-shaped guide tube 21, the assembly seat 19 and the rotating tube 18, and finally sucks out the dust on the welding surface of the lower transverse curved rod 4 or the longitudinal curved rod 5 from the air outlet 8 of the guide tube 7, thereby achieving the operation of first dust suction and then fixing, avoiding the subsequent impact of dust on the stability of the fixing hook 13 fixing the transverse curved rod 4 or the longitudinal curved rod 5. After each transverse curved rod 4 or longitudinal curved rod 5 is welded, the position of the guide tube 7 is adjusted again and switched to the cooling mode, so that the cooling air flow passes through the air outlet 8 of the guide tube 7 to quickly cool the welding part below, preventing the operator from contacting the high-temperature part and causing burns.
