Description

Technical Field

[0001] This utility model relates to the field of spinning equipment technology, and in particular to a device for disassembling and assembling the spinning wheel of a large vertical spinning machine. Background Technology

[0002] A vertical spinning machine is a metal forming device primarily used to press metal billets into thin-walled rotating parts through rotary motion. Vertical spinning machines are also widely used in the automotive and machinery manufacturing industries for producing products such as steel pipes, wheel rims, and liquid reservoir bodies. Different types of spinning wheels need to be changed when spinning different products. Because these wheels are quite heavy, typically weighing tens of kilograms, and sometimes even hundreds of kilograms, changing them often involves using a forklift fork to pull the wheel along and align it with the axle. Without any safety measures, the wheel is prone to slipping on the forks, easily falling and injuring people, posing an extremely high risk.

[0003] Therefore, in order to address the above problems, a device for disassembling and assembling the spinning wheel of a large vertical spinning machine is proposed to solve these problems. Utility Model Content

[0031] Example 1, as Figures 1 to 5 As shown, a device for disassembling and assembling the spinning wheel of a large vertical spinning machine includes a lifting platform 1 and a mobile trolley 2. The lifting platform 1 is mounted on the mobile trolley 2. A first support arm 3 is mounted on the lifting platform 1, a second support arm 4 is mounted on the first support arm 3, a telescopic platform 5 is mounted on the second support arm 4, and a hydraulic gripper 6 is mounted on the telescopic platform 5. The lifting platform 1 is raised to below the spinning wheel of the spinning machine, and the hydraulic gripper 6 is activated to clamp the spinning wheel. After clamping, the spinning wheel is disassembled. After disassembly, the lifting platform 1 is lowered and moved to a storage position by the mobile trolley 2. The hydraulic gripper 6 clamps the spinning wheel to be replaced, and the mobile trolley 2 moves it to below the spinning machine. The lifting platform 1 is then raised, the position of the hydraulic gripper 6 is adjusted, and the spinning wheel is then installed.

[0032] A first hollow rotating platform 7 is installed on the lifting platform 1. A first support arm 3 is installed on the first hollow rotating platform 7. The upper part of the first support arm 3 is bent. A second hollow rotating platform 8 is installed on the upper part of the first support arm 3. A second support arm 4 is installed on the second hollow rotating platform 8. The second support arm 4 is horizontally positioned. The first hollow rotating platform 7 drives the first support arm 3 to rotate, and the second hollow rotating platform 8 drives the second support arm 4 to rotate. The rotation of the first support arm 3 and the second support arm 4 facilitates the adjustment of the angle of the hydraulic gripper 6.

[0033] Example 1, as Figures 1 to 5 As shown, the telescopic platform 5 is connected to the rack 9, which is slidably mounted in the mounting groove 10. The rack 9 is meshed with the gear 11, and the mounting groove 10 is located on the second support arm 4. The rotation of the gear 11 drives the rack 9 to move, thereby controlling the telescopic platform 5 to extend and retract, and adjusting the position of the hydraulic gripper 6.

[0034] A mounting platform 12 is provided on the second support arm 4. A limiting groove 13 is provided inside the mounting platform 12. A connecting shaft 14 is rotatably mounted inside the limiting groove 13. A gear 11 is mounted on the connecting shaft 14. The connecting shaft 14 is connected to a motor 15, which is located outside the mounting platform 12. The limiting groove 13 in the mounting platform 12 prevents the gear 11 from being misaligned. The gear 11 is driven to rotate by the motor 15.

[0035] A support plate 16 is installed below the second support arm 4, extending out of the second support arm 4. A slide rail 17 is installed on the support plate 16, and a mounting platform 12 is slidably connected to the slide rail 17 via a slider. Reinforcing plates 18 are symmetrically arranged on both sides of the support plate 16, and the reinforcing plates 18 are connected to the second support arm 4. The support plate 16 supports the mounting platform 12, and the reinforcing plates 18 increase the strength of the support plate 16 and prevent it from bending.

[0036] The telescopic platform 5 is symmetrically equipped with limiting rods 19, which are in the same direction as the rack 9. The limiting rods 19 are slidably engaged in the guide hole 20, which is located inside the second support arm 4. The cooperation between the limiting rods 19 and the guide hole 20 prevents the telescopic platform 5 from misaligning during movement and also provides support.

[0037] Multiple hydraulic support frames 21 are symmetrically arranged on both sides of the mobile trolley 2. When the rotating wheel is disassembled or assembled, the hydraulic support frames 21 are activated, and the hydraulic support frames 21 contact the ground to improve overall stability.

[0038] A hydraulic cylinder 22 is installed on the telescopic platform 5, and the hydraulic cylinder 22 is connected to the hydraulic gripper 6.

[0039] Working principle: When the spinning wheel needs to be disassembled, the trolley 2 moves to the bottom of the spinning wheel, the lifting platform 1 is started, the angles of the first support arm 3 and the second support arm 4 are adjusted, the position of the hydraulic gripper 6 is adjusted, and the hydraulic gripper 6 is started to clamp the spinning wheel. The operator then disassembles the spinning wheel. The disassembled spinning wheel is transported to the storage position by the trolley 2. When the spinning wheel is installed, the hydraulic gripper 6 clamps the spinning wheel and is brought to the bottom of the spinning machine by the trolley 2. The lifting platform 1 is started, and the angles of the first support arm and the second support arm 4 are adjusted. The position of the hydraulic gripper 6 is adjusted so that the spinning wheel is in the installation position. The operator then installs the spinning wheel.
