Description

Technical Field

[0001] The utility model relates to a supporting device, in particular to an auxiliary supporting device for special-shaped parts. Background Art

[0002] Special-shaped parts refer to mechanical parts with irregular shapes. After being formed, special-shaped parts also need to be processed, such as drilling, grinding and milling. When processing special-shaped parts, they need to be clamped and fixed.

[0003] When existing conventional clamps are used to clamp special-shaped parts, due to the irregular shape of the special-shaped parts, a certain part of the special-shaped part will be suspended between the clamp, which will cause the suspended part of the special-shaped part to be unable to be clamped and fixed due to structural and shape limitations. When cutting this part, trembling, vibration and elastic deformation will occur, which will affect the quality and efficiency of the product processing.

[0004] Therefore, a device is needed to support or clamp the special-shaped suspended part to overcome the vibration or elastic deformation during cutting and ensure the processing quality of the part.

[0005] The conventional method is to use screw support or wedge support, but the support force of this support method relies entirely on manual control, and it is difficult to achieve consistency in preload force. The processed products have poor consistency and are extremely unstable. Utility Model Content
