Description

Technical Field

[0001] This invention relates to the field of rail transit equipment manufacturing and maintenance technology, and in particular to a bogie wheel damping ring welding positioning and clamping device. Background Technology

[0002] In the manufacturing of rail transit equipment, bogie wheels require multiple processes, including damping ring welding, hub hole grinding, and overall inspection. Traditional operating methods have many drawbacks: When welding damping rings, "F"-shaped clamping tools are commonly used for positioning and clamping. These tools are cumbersome to install, requiring repeated adjustments and are extremely inconvenient to operate. More importantly, poor contact between the "F"-shaped clamp and the workpiece can easily generate an electric arc at the point where welding current passes, burning the wheel surface or damping ring surface, causing product scrap and severely impacting product quality. Furthermore, existing clamping devices are functionally limited and cannot simultaneously meet the combined needs of vertical wheel fixing for hub hole grinding and inspection, as well as damping ring welding, leading to production interruptions, low equipment utilization, and overall low operational efficiency.

[0003] Therefore, there is an urgent need to develop an integrated special device that can safely and efficiently meet the operational requirements of damping ring welding and hub hole grinding in the vertical position of the wheel. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a bogie wheel damping ring welding positioning and clamping device, which can achieve stable vertical fixation of the wheel and safely and efficiently complete the damping ring welding operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A bogie wheel damping ring welding positioning clamping device includes a support base, the support base including a base, a support frame for vertically supporting the wheel provided on the base, an insulating material layer provided on the support surface of the support base that contacts the wheel, two damping ring clamping devices symmetrically arranged on the front and rear sides of the support base, each damping ring clamping device including a cylinder welded to the support base, a rotating arm passing through the cylinder, a clamping head provided at the top end of the rotating arm, the clamping head having a groove corresponding to the shape of the damping ring, and a fastening nut threadedly connected to the tail end of the rotating arm, the position of the rotating arm within the cylinder being adjustable by the fastening nut, thereby applying a clamping force to the damping ring through the clamping head.

[0022] Reference Figures 1-2 A welding positioning and clamping device for a bogie wheel damping ring includes a support base 1. To ensure greater product robustness, the support base 1 is welded from structural steel and possesses sufficient rigidity and stability to support the upright wheel 4. The support base 1 can stably and vertically fix the wheel 4 onto the support base 1, facilitating operations such as hub hole grinding and wheel inspection.

[0023] Reference Figure 3The support base 1 includes a base 11, which includes a base plate 111. Front and rear trapezoidal frames 112 and 113 are symmetrically arranged on the base plate 111, and a support plate 114 is provided on the top of the front and rear trapezoidal frames 112 and 113. A V-shaped seat 115 for supporting the wheel is provided on the support plate 114. A support frame 12 for vertically supporting the wheel 4 is provided on the base 11. The support frame 12 includes front and rear crossbars 121 and 122 arranged on the support plate 114, and U-shaped frames 123 for clamping the wheel are symmetrically arranged at both ends of the front and rear crossbars 121 and 122. A layer of soft insulating material 2 is firmly adhered or embedded on the upper surface of the V-shaped seat 115 and the inner surface of the U-shaped frame 123. This material layer is preferably made of wear-resistant, oil-resistant, and highly insulating engineering plastic or insulating rubber. The insulating material layer 2 mainly contacts the sides of the wheel and the wheel tread. Its main function is to prevent the hard metal base frame from scratching the wheel surface. In addition, it serves as a buffer layer to enhance the stability of the wheel placement. Moreover, it serves as a reliable insulating barrier to prevent welding current from accidentally forming a circuit through the base frame and generating an electric arc.

[0024] Reference Figure 4 Two damping ring clamping devices 3 are symmetrically arranged on the front and rear sides of the support base 1. In order to ensure that the damping ring clamping device 3 applies a uniform clamping force to the damping ring and ensure that the damping ring fits tightly and is accurately positioned with the wheel, the two damping ring clamping devices 3 located on the same side are arranged in a figure-eight pattern. By cooperating with four symmetrically arranged rotatable damping ring clamping units 3, the positioning and clamping requirements of the welding operation of the damping rings 5 ​​on both sides of the wheel 4 are effectively met.

[0025] The damping ring clamping device 3 includes a cylinder 31 welded to the support base 1. A rotating arm 32 passes through the cylinder 31 and can rotate freely within the cylinder 31. A clamping head 33 is provided at the top of the rotating arm 32. The clamping head 33 has a groove 331 corresponding to the shape of the damping ring 5. The groove is arc-shaped or V-shaped to provide a larger contact area and a more stable clamping force. A fastening nut 34 is threaded to the tail end of the rotating arm 32. The position of the rotating arm 32 within the cylinder 31 can be adjusted by the fastening nut 34, thereby applying a clamping force to the damping ring 5 through the clamping head 33. The clamping head 33 is made of conductive material, and welding current can be introduced through the clamping head 33 for welding.

[0026] The working process of this device is as follows: First, the wheel 4 is vertically hoisted onto the support base 1 using lifting equipment, and supported and protected by the insulating material layer 2. At this time, the wheel 4 is in a stable upright position, and the operator can easily perform grinding operations on the hub hole or conduct a comprehensive inspection of the wheel 4. When it is necessary to weld the damping ring 5, the damping ring 5 is initially placed in the specified positions on both sides of the wheel 4. Then, the four damping ring clamping devices 3 are operated in sequence, rotating the rotating arm 32 to align and clamp the clamping head 33 with the damping ring 5, and then rotating the fastening nut 34 to apply clamping force synchronously from the four damping ring clamping devices 3 from the symmetrical direction, ensuring that the damping ring 5 fits tightly with the wheel 4 and is accurately positioned. Because the clamping head 33 has good contact with the damping ring 5 and there is reliable insulation between the support base 1 and the wheel 4, the welding current can be stably introduced through the clamping head 33, effectively avoiding the generation of electric arc. After welding is completed, the damping ring clamping device 3 is released, and the wheel 4 can be lifted away to proceed to the next cycle of operation.

[0027] This device integrates multiple functions such as vertical wheel fixing, hub hole grinding, wheel inspection, and damping ring welding, centralizing processes, reducing workpiece turnover, and improving equipment utilization and production efficiency. Furthermore, the device provides uniform and stable clamping force to the damping ring 5 through four symmetrically arranged damping ring clamping devices 3. The design of the insulating material layer 2 and the clamping head 33 ensures good electrical contact and insulation performance, fundamentally eliminating the risk of burning the wheel and damping ring due to arcing caused by poor contact. Moreover, the rotatable rotating arm 32 allows the device to quickly adapt to wheels 4 and damping rings 5 ​​of different sizes, and the clamping position is easy to adjust, significantly reducing the labor intensity of operators and improving work efficiency and quality consistency.

[0028] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
