[0002] In the manufacturing of ultra-large mining machinery and heavy engineering machinery, the chassis wheel system (such as the track roller body) is a core load-bearing component, and its welding quality directly affects the operational safety and service life of the equipment. The track roller body needs to withstand the weight of the entire machine and the impact and friction loads under complex working conditions for a long time. Therefore, the welding fixtures for the chassis wheel system are key equipment to ensure welding accuracy, efficiency and safety. Existing welding fixtures mostly lack active protection during the welding process, making it inconvenient to shield against welding spatter, which can endanger the safety of operators and potentially damage surrounding equipment. Therefore, those skilled in the art have provided a rotary welding fixture for ultra-large chassis wheel systems to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to provide a rotary welding fixture for ultra-large chassis wheel systems to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A rotary welding fixture for ultra-large chassis wheel systems includes a fixture base, a positioning and adjustment structure, and a splash-proof adjustment structure. The fixture base has four fixed support blocks at its bottom corners. A rotating shaft is rotatably connected inside the fixture base, and a placement platform is fixedly connected to the top of the rotating shaft through the fixture base. The placement platform has a positioning and adjustment structure inside. Round rods are rotatably connected to the top of the fixture base and to both sides of the placement platform. A splash-proof plate is fixedly connected to the top of each round rod. The splash-proof plate is arc-shaped and has a transparent window inside. The fixture base also has a splash-proof adjustment structure inside.

[0005] As a further embodiment of this utility model: the positioning adjustment structure includes a first positive and negative lead screw, a first guide rod, a first threaded sleeve and a slide groove. The first positive and negative lead screw is rotatably connected inside the placement platform, and both ends of the first positive and negative lead screw are fixedly connected to a turntable through the placement platform. The first guide rod is fixedly connected inside the placement platform, and two first threaded sleeves are threadedly connected to the first positive and negative lead screw.

[0006] As a further improvement of this utility model: the top of the placement platform has two sliding grooves that are adapted to the first threaded sleeve, and the top of the first threaded sleeve is fixedly connected to a positioning block through the sliding groove.

[0007] As a further embodiment of this utility model: the splash-proof adjustment structure includes a second guide rod, a second positive and negative lead screw, a second threaded sleeve, a driving rack and a driven gear. The second guide rod is fixedly connected inside the tooling base, and the second positive and negative lead screw is rotatably connected inside the tooling base. Two second threaded sleeves are threadedly connected to the second positive and negative lead screw.

[0008] As a further embodiment of this utility model: one end of the second threaded sleeve is fixedly connected to a drive rack, and the bottom end of the round rod penetrates into the tooling base and is fixedly connected to a driven gear, and the drive rack and the driven gear are meshed together.

[0009] As a further embodiment of this utility model: a mounting box is fixedly connected to the outer wall of the tooling base, and a second motor is provided inside the mounting box, and one end of the second positive and negative lead screw passes through the inside of the mounting box and is fixedly connected to the output end of the second motor.

[0010] As a further improvement of this utility model: two rollers are fixedly connected to the bottom of the placement platform, and a circular groove adapted to the rollers is provided at the top of the tooling base.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This device adjusts the positions of two positioning blocks using a positioning adjustment structure. Rotating the turntable drives the first positive and negative lead screws to rotate, causing the two first threaded sleeves to move in opposite directions along the slide groove. The positioning blocks at the top of the first threaded sleeves move synchronously with them. The spacing is adjusted according to the size of the wheel system components. Then, the support wheel body is hoisted to the top of the placement platform, allowing the positioning blocks to be inserted into the positioning holes of the support wheel body. The two positioning blocks limit the position of the support wheel body, preventing component displacement due to vibration or rotation during welding. This ensures accurate weld position and uniform weld bead. By adjusting the positions of the two positioning blocks, stable positioning of wheel system components of different specifications is achieved, preventing component displacement during welding. This device adjusts the position of the two splash guards using a splash-proof adjustment structure. By starting the second motor, the second positive and negative lead screws rotate, causing the two second threaded sleeves to move in opposite directions. This synchronously drives the active rack to move, which meshes with the driven gear, driving the round rod to rotate. This adjusts the angle of the two arc-shaped splash guards. When welding is required, the two splash guards can be controlled to close inward, forming a semi-enclosed protective area. This ensures that splashes are effectively blocked, preventing them from falling onto the operator or surrounding equipment, thus improving the device's protective performance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0021] Example 1: Refer to Figure 1-4This embodiment provides a rotary welding fixture for ultra-large chassis wheel systems, including a fixture base 1, a positioning adjustment structure, and a splash-proof adjustment structure. The fixture base 1 has four fixedly connected support blocks 25 at its bottom corners. A rotating shaft 4 is rotatably connected inside the fixture base 1, and the top of the rotating shaft 4 passes through the fixture base 1 and is fixedly connected to a placement platform 6. The placement platform 6 has a positioning adjustment structure inside. Round rods 19 are rotatably connected to the top of the fixture base 1 and to both sides of the placement platform 6. A splash-proof plate 23 is fixedly connected to the top of the round rods 19, and the splash-proof plate 23 is arc-shaped with a transparent window 24 inside. The fixture base 1 has a splash-proof adjustment structure inside.

[0022] The positioning adjustment structure includes a first positive and negative lead screw 9, a first guide rod 11, a first threaded sleeve 12, and a slide groove 13. The first positive and negative lead screw 9 is rotatably connected inside the placement platform 6, and both ends of the first positive and negative lead screw 9 are fixedly connected to a turntable 10 through the placement platform 6. The first guide rod 11 is fixedly connected inside the placement platform 6. Two first threaded sleeves 12 are threadedly connected to the first positive and negative lead screw 9. Two slide grooves 13 adapted to the first threaded sleeves 12 are opened at the top of the placement platform 6, and the top of the first threaded sleeve 12 is fixedly connected to a positioning insert 14 through the slide groove 13.

[0023] The bottom of the placement platform 6 is fixedly connected to two rollers 7, and the top of the tooling base 1 is provided with a circular groove 8 that matches the rollers 7.

[0024] The bottom end of the rotating shaft 4 passes through the tooling base 1 and is fixedly connected to a large gear 5. The bottom end of the tooling base 1 is fixedly connected to a first motor 2, and a small gear 3 is fixedly connected to the output end of the first motor 2, and the small gear 3 meshes with the large gear 5.

[0025] In this implementation, the tooling is based on the tooling base 1, with four support blocks 25 at the bottom providing stable support to prevent equipment shaking from affecting accuracy during welding. The placement platform 6 serves as a load-bearing platform for the wheel system components, with two rollers 7 at its bottom embedded in the circular grooves 8 at the top of the tooling base 1 to ensure the stability of the placement platform 6 during rotation. Rotating the turntable 10 drives the first positive and negative lead screws 9 to rotate inside the placement platform 6. Since the two first threaded sleeves 12 are respectively connected to the positive and negative threaded sections of the first positive and negative lead screws 9 and are limited by the first guide rod 11, the two first threaded sleeves 12 will move towards or in opposite directions along the slide groove 13. The positioning inserts 14 at the top of the first threaded sleeves 12 move synchronously with the first threaded sleeves 12, adjusting the spacing according to the size of the wheel system components. Then, the support wheel body is hoisted to the top of the placement platform 6, so that the positioning inserts 14 are inserted into the positioning holes of the support wheel body. The positioning of the support wheel body is completed by the limiting of the two positioning inserts 14, preventing welding. During the welding process, vibration and rotation can cause component displacement. To ensure accurate weld position and uniform weld bead, the positions of the two positioning blocks 14 are adjusted to achieve stable positioning of wheel system components of different specifications, preventing component displacement during welding. During welding, the first motor 2 can be started, and its output end drives the pinion 3 to rotate. The pinion 3 meshes with the large gear 5 at the bottom of the rotating shaft 4, thereby driving the rotating shaft 4 to rotate. The top of the rotating shaft 4 is fixedly connected to the placement platform 6, so the placement platform 6 rotates synchronously with the rotating shaft 4, driving the support wheel body positioned on it to rotate. The rotation of the support wheel body allows the operator to complete multi-angle welding operations in a fixed position. The speed of the first motor 2 can be adjusted according to welding requirements. When performing circumferential welding, it needs to rotate at a uniform speed, while the first motor 2 can be paused for fixed-point welding, so that the parts of the workpiece to be welded are aligned with the welding gun in sequence. There is no need to frequently move the welding equipment, which is especially suitable for circumferential welding of ultra-large wheel system components, improving welding efficiency and weld consistency.

[0026] Example 2: Refer to Figure 1-6 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that the splash-proof adjustment structure includes a second guide rod 15, a second positive and negative lead screw 16, a second threaded sleeve 17, a driving rack 18, and a driven gear 20. The tooling base 1 is fixedly connected to the second guide rod 15, and the tooling base 1 is rotatably connected to the second positive and negative lead screw 16. Two second threaded sleeves 17 are threadedly connected to the second positive and negative lead screw 16.

[0027] One end of the second threaded sleeve 17 is fixedly connected to a drive rack 18, and the bottom end of the round rod 19 passes through the tooling base 1 and is fixedly connected to a driven gear 20. The drive rack 18 and the driven gear 20 are meshed together. A mounting box 21 is fixedly connected to the outer wall of the tooling base 1, and a second motor 22 is installed inside the mounting box 21. One end of the second positive and negative screw 16 passes through the mounting box 21 and is fixedly connected to the output end of the second motor 22.

[0028] In this implementation, after the support roller body is placed, the second motor 22 inside the mounting box 21 can be started. Its output end drives the second positive and negative lead screw 16 to rotate, causing the two second threaded sleeves 17 to move in opposite directions along the second positive and negative lead screw 16 under the limit of the second guide rod 15. This synchronously drives the active rack 18 to move. The active rack 18 meshes with the driven gear 20, driving the round rod 19 to rotate, thereby adjusting the angle of the two arc-shaped anti-splash plates 23. When welding is required, the two anti-splash plates 23 can be controlled to close inward to form a semi-enclosed protective area, ensuring that the splashes are effectively blocked and preventing them from falling onto the operator or surrounding equipment, thus improving the protective performance of the device. The operator can observe the welding area through the transparent window 24 outside the anti-splash plate 23. After welding is completed, the first motor 2 is turned off to stop the rotation of the placement platform 6. Then, the second motor 22 is started to control the anti-splash plate 23 to open outward to the maximum angle for easy removal of the part. Then, the welded support roller body is removed from the placement platform 6 by the hoisting equipment.
