Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a welding device for tower wheels. Background Technology

[0002] With the continuous development of technology, bicycles have been constantly improved, and a large number of new types of bicycles have been developed, such as mountain bikes, road bikes, and off-road bikes. Most bicycles nowadays have gears, which are used to change the speed of the bicycle according to the terrain requirements, ensuring the safety and comfort of riding and bringing great convenience to people.

[0003] like Figure 4 The diagram shows a tower wheel, which has a shaft core 27 and several wheel pieces 28 with gradually increasing diameters welded to the periphery of the shaft core. When producing the tower wheel, the wheel pieces need to be welded to the shaft core one by one. The current welding device has the following problems when welding the tower wheel: (1) Because there is a gap between the wheel pieces, it is necessary to keep the gap between adjacent wheel pieces during welding. However, during welding, the upper wheel piece will stick to the lower wheel piece, and it is impossible to separate the upper wheel piece from the lower wheel piece, which is not conducive to welding. Moreover, if the wheel piece is unstable during welding, it will also lead to poor welding quality. (2) During welding, by driving the shaft core to rotate and holding the welding gun, the connection between the wheel piece and the shaft core can be welded 360°. However, the welding gun is prone to shaking, resulting in poor welding quality and low welding efficiency. Utility Model Content

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) During welding, the wheel pieces are clamped by the clamping mechanism to keep them stable on the one hand, and to make the upper and lower adjacent wheel pieces have a gap to facilitate welding and improve welding quality.

[0017] (2) During welding, the shaft core is fixed by the pneumatic chuck, the wheel is placed on the shaft core, and then the first sliding block is driven by the first lifting mechanism to adjust the height of the clamping mechanism and clamp the wheel to keep it stable. Then the height of the second sliding block is adjusted by the second lifting mechanism and the height of the welding mechanism is adjusted. Then the second cylinder works to adjust the angle of the welding gun. By extending the first cylinder, the welding gun can be moved to the connection between the wheel and the shaft core, so that the welding end of the welding gun and the connection between the wheel and the shaft core can contact and weld. After one part of the wheel is welded to the shaft core, the clamping mechanism releases the wheel and then drives the rotating column to rotate by the drive mechanism, which drives the pneumatic chuck to rotate. At this time, the welding gun remains stationary. By rotating the shaft core and the wheel simultaneously, the connection between the shaft core and the wheel can be welded 360°, which greatly improves the welding efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-3A welding device for a tower wheel includes a base 1, with wall plates 2 connected to both sides of the base 1, and a top plate 3 connected to the two wall plates 2. A rotating column 4 is rotatably connected to the base 1. A drive mechanism for driving the rotating column 4 to rotate is provided inside the base 1. A pneumatic chuck 5 is connected to the upper end of the rotating column 4. The pneumatic chuck can fix the shaft core, and the drive mechanism can drive the rotating column to rotate. Specifically, the drive mechanism includes a first motor 14 installed in the base, a transmission shaft connected to the first motor through a coupling, a main gear 15 connected to the transmission shaft, and a secondary gear 16 connected to the rotating column. The main gear 15 and the secondary gear 16 mesh. When the first motor 14 is started, the rotating column 4 is driven to rotate through the cooperation of the main gear 15 and the secondary gear 16, thereby driving the pneumatic chuck 5 and the shaft core on it to rotate.

[0026] A first lifting mechanism is provided on one side of the pneumatic chuck on the base 1, and a first slide 6 is connected to the first lifting mechanism. A clamping mechanism is installed on the first slide 6. Specifically, the first lifting mechanism includes a first lead screw 20 rotatably connected to the base and the top plate, a first guide rod 21 connected to the base and the top plate, and a second motor 22 installed on the top plate and driven by the first lead screw. The first slide 6 is threadedly connected to the first lead screw 20 and slidably connected to the first guide rod 21. When the second motor 22 is started, the first lead screw 20 is rotated, which in turn moves the first slide 6 up and down to bring the clamping mechanism to a suitable height.

[0027] The clamping mechanism includes a support plate 17 mounted on the first slide and facing the pneumatic chuck. A third cylinder 18 is mounted on the support plate 17, and a finger cylinder 19 is connected to the telescopic end of the third cylinder 18. When the first slide 6 reaches the required height, the third cylinder 18 extends, driving the finger cylinder 19 to move toward the shaft on the pneumatic chuck 5, and clamping the wheel piece with the finger cylinder 19 to keep the wheel piece stable.

[0028] A second lifting mechanism is provided on the base 1 on the other side of the pneumatic chuck, and a second slide 7 is connected to the second lifting mechanism. A welding mechanism is installed on the second slide 7. The second lifting mechanism includes a second lead screw 23 rotatably connected to the base and the top plate, a second guide rod 24 connected to the base and the top plate, and a third motor 25 installed on the top plate and driven by the second lead screw. The second slide 7 is threadedly connected to the second lead screw 23 and slidably connected to the second guide rod 24. When the third motor 25 is started, the second lead screw 23 is rotated, which drives the second slide 7 to move up and down, thereby driving the welding mechanism to move up and down.

[0029] The welding mechanism includes a first hinge seat 8 connected to the upper part of the second slide and extending towards the pneumatic chuck. A first cylinder 9 is hinged to the first hinge seat 8. The telescopic end of the first cylinder 9 is connected to a mounting plate 10, on which a welding torch 26 is mounted. A second hinge seat 11 is connected to the lower part of the second slide 7. A third hinge seat 12 is connected to the first cylinder 9. A second cylinder 13 is hinged to the second hinge seat 11. The telescopic end of the second cylinder 13 is movably connected to the third hinge seat 12. The extension of the second cylinder 13 can adjust the angle of the welding torch 26, and the extension of the first cylinder 9 can adjust the distance reached by the welding torch 26 so that the welding torch 26 can contact the wheel and the shaft.

[0030] The working principle of this embodiment is as follows:

[0031] During welding, such as Figure 1 As shown, the shaft core is fixed by the pneumatic chuck 5, and then a wheel piece 28 is fitted onto the shaft core 27. The first lifting mechanism drives the first slide 6 to move, adjusting the height of the clamping mechanism and holding the wheel piece 28 to maintain stability. Next, the second lifting mechanism adjusts the height of the second slide 7 and the welding mechanism. Then, the second cylinder 13 operates, adjusting the angle of the welding torch 26. Through the extension of the first cylinder 9, the welding torch 26 can be moved towards the connection between the wheel piece and the shaft core, allowing the welding end of the welding torch 26 to contact the bottom surface of the connection between the wheel piece and the shaft core for welding. After one part of the wheel piece 28 is welded onto the shaft core 27, the clamping mechanism releases the wheel piece, and the drive mechanism drives the rotating column 4 to rotate, causing the pneumatic chuck 5 to rotate. At this time, the welding torch 26 remains stationary. By rotating the shaft core 27 and the wheel piece 28 simultaneously, 360° welding can be performed on the bottom surface of the connection between the shaft core and the wheel piece, greatly improving welding efficiency. Figure 2 As shown, the first cylinder 9 then retracts, retracting the welding torch 26. The second lifting mechanism then drives the second slide 7 to rise, adjusting the angle and length of the welding torch 26 so that it can contact the top surface of the connection between the wheel and the shaft core, thus achieving welding of the top surface. After the first wheel is welded, other wheel pieces (such as...) are welded onto the shaft core sequentially. Figure 3 (As shown), continue until all welding is completed.
