AI Technical Summary
The existing outer nut is difficult to clamp effectively during drilling, resulting in uneven clamping and easily causing deformation of the one-piece molded washer.
An adjustable clamping device is adopted, including components such as mounting blocks, clamping plates, V-shaped plates, and threaded rods. By adjusting the turntable, the threaded rod is driven to rotate, causing the clamping plate to move within the slide rail, thereby achieving stable clamping of the outer nut. The guide wheel reduces sliding resistance and ensures that the washer is supported within the U-shaped groove.
This achieves stable clamping during drilling of the outer nut, preventing gasket deformation and improving drilling quality and efficiency.
