The Principle of Strong Clamp Tool Handle and the Locking Principle of Strong Clamp Tool Handle

The locking principle of powerful chuck handle: Similar to the principle of ratchet bearing, the needle rolling is thick in one direction on the conical surface and thin in the opposite direction, instead of rolling on the contour surface. That is to say, the clearance is smaller in one direction, locking, and the clearance is larger and loosening in the other direction. When the locking sleeve rotates clockwise, it drives the cage and the needle to rotate. When the needle falls into the groove of 0.8 on the chuck body, it tilts the cage due to the guiding effect. Continuing to rotate the groove of 0.8, the needle moves upward, which drives the cage to move together, forming a spiral upward motion. Because of the taper effect, the chuck body deforms inward and forms the locking force. Release the helix downward counterclockwise. The design of inner hole groove and uniform elastic deformation can ensure excellent precision. Special needle bearing arrangement design, low locking resistance, high clamping force, can produce 280 KGM clamping force.

Powerful chuck handle is suitable for milling machine, heavy cutting and precision cutting. Powerful chuck TOOL HOLDER is a common Tool Holder in cutting process. It is used to clamp straight shank cutters such as milling cutters and reamers. The clamping deformation of clamping spring is small. The diameter tolerance of clamping tool holder is h6. The clamping force is larger and the clamping precision is better. Different cylinder clamps can be replaced to clamp milling cutters and reamers with different shank diameters.
