Description

Technical Field

[0001] This utility model relates to the technical field of correction devices, specifically a correction device for the outer steel tube of a steering wheel. Background Technology

[0002] As the core control component of the car steering system, the shape accuracy of the outer steel tube of the steering wheel directly determines the assembly adaptability, handling stability and service life of the steering wheel. In actual production, after the outer steel tube of the steering wheel undergoes processes such as bending, welding and heat treatment, it is prone to radial roundness deviation and axial flatness defects due to factors such as stress release, welding deformation and tooling clamping deviation. Therefore, it is necessary to repair the shape accuracy through the correction process.

[0003] Currently, existing outer ring steel pipes generally adopt a step-by-step correction mode during straightening. They need to first use specialized roundness correction equipment, such as a three-jaw jacking straightening machine, to complete the radial roundness adjustment of the steel pipe, and then transfer it to flatness correction equipment, such as a roller pressing flattening machine, for axial repair. This process requires two clamping and positioning, which not only increases the workpiece handling time and reduces production efficiency, but also easily leads to a decrease in correction accuracy due to repeated positioning errors, making it difficult to simultaneously meet the dual accuracy requirements of roundness and flatness. Therefore, a steering wheel outer ring steel pipe straightening device is proposed to address the above problems. Utility Model Content

[0032] A rotating disk 29 is rotatably mounted on the support shaft 21 below the fixed disk 22. The rotating disk 29 has multiple equally spaced arc-shaped grooves 210. A connecting rod 211 is inserted through each arc-shaped groove 210. The top of the connecting rod 211 is fixed to the bottom of multiple sliders 25. A wedge 28 is fixed to the outer side of each slider 25. The inclined surface of the wedge 28 is inserted through the opening on the upper surface of the guide groove 23.

[0033] A gear ring 212 is fixed to the side curved surface of the rotating disk 29. A motor 213 is arranged next to the gear ring 212. A gear 214 is fixed to the output end of the motor 213, and the gear 214 meshes with the gear ring 212 for transmission. The motor 213 is fixed on the base plate 1.

[0034] The leveling assembly 3 includes a support plate 31 fixed to the top of the bracket 12. Multiple U-shaped frames 32 are provided below the support plate 31. Each U-shaped frame 32 is connected to a second hydraulic rod 34, and the multiple second hydraulic rods 34 are fixed through the support plate 31.

A second internal spline sleeve 44 is slidably fitted at the bottom end of the first internal spline sleeve 42, and the second internal spline sleeve 44 is fixed on one of the tapered shafts 27.

[0036] A second gear 46 is fixed to the outer wall of the first inner spline sleeve 42. A second motor 47 is fixed to the mounting plate 41. A third gear 48 is fixed to the output end of the second motor 47, and the third gear 48 meshes with the second gear 46 for transmission. A limit plate 45 is fixed to the top of the spline shaft 43.

[0037] In current systems, the outer ring steel pipe is typically straightened using a step-by-step method. First, a dedicated roundness correction device is used to adjust the radial roundness of the steel pipe, then it is transferred to a flatness correction device for axial repair. This process requires two clamping and positioning operations, which not only increases workpiece handling time and reduces production efficiency but also easily leads to decreased correction accuracy due to repeated positioning errors, making it difficult to simultaneously meet the dual accuracy requirements of roundness and flatness. In this solution, the outer ring body 11 is placed on a fixed plate 22, and then the first motor 213 is controlled to operate. When the first motor 213 is driven, it passes through the first gear. 214 drives the gear ring 212, thereby causing the rotating disk 29 to rotate below the fixed disk 22. When the rotating disk 29 rotates, under the arc-shaped guidance of the arc-shaped groove 210, and with the limiting action of the connecting rod 211 and the arc-shaped groove 210, it drives the slider 25 to slide synchronously on the limiting rod 24, causing multiple sliders 25 to expand inwards or outwards simultaneously. This expansion, in turn, drives multiple tapered shafts 27 to expand outwards. Under the internal support of the multiple tapered shafts 27, the outer ring body 11 is centered and clamped. Guided by the tapered surfaces of the multiple tapered shafts 27, the outer ring body 11 is further centered and clamped. The outer ring body 11 is attached to the upper surface of the turntable 26, and guided by the inclined surface of the wedge block 28, the outer ring body 11 is accurately guided above the turntable 26. Under the internal support and fixation of multiple tapered shafts 27, the inner diameter of the outer ring body 11 is squeezed and adjusted. Then, the first hydraulic rod 14 is extended, causing the drive assembly 4 to move horizontally above one of the tapered shafts 27. Then, the spline shaft 43 is lifted, so that the spline shaft 43 is raised above the second inner spline sleeve 44. When the bottom end of the spline shaft 43 is aligned with the opening of the second inner spline sleeve 44, the bottom end of the spline shaft 43 is fitted and inserted into the second inner spline sleeve 44. The first inner spline sleeve 42 and the second inner spline sleeve 44 are connected by a transmission. Then, the second motor 47 is controlled to run. When the second motor 47 runs, it drives the second gear 46 through the third gear 48, which in turn drives the first inner spline sleeve 42 to rotate on the mounting plate 41. Under the transmission action of the spline shaft 43, the second inner spline sleeve 44 is driven to rotate synchronously, which in turn drives one of the tapered shafts 27 to rotate. Then, under the internal support of multiple tapered shafts 27, the outer ring body 11 is driven to rotate, so that the roundness is further corrected when the outer ring body 11 rotates, thereby improving the correction accuracy.

[0038] Subsequently, multiple hydraulic rods 34 are extended to lower the height of multiple roller shafts 33, which are staggered between multiple tapered shafts 27 and roll against the outer ring body 11. Under the downward pressure of the multiple hydraulic rods 34, the outer ring body 11 is continuously rolled to squeeze and adjust its flatness, thereby achieving flatness correction and simultaneously correcting roundness and flatness, thus improving ease of use.

[0039] This method effectively corrects the steel tube on the outer ring of the steering wheel, making it more convenient to use than traditional correction methods and significantly improving production efficiency.
