Problems solved by technology

[0002] The existing tap chucks are divided into two categories: fixed clamping and flexible clamping. Their advantages are that the fixed tap chuck has simple structure, small size, strong clamping force, and small tap jump after clamping. It is suitable for various Tapping in the same direction; the flexible tap chuck can automatically center the tap through clearance adjustment, and protect the tap and thread from damage by adjusting the stop force; their disadvantages are that the fixed tap chuck cannot adjust the tapping force , and the tapping center cannot be adjusted, which may easily cause damage to the tap or thread; the flexible tap chuck has a complex structure, large volume, and relatively small clamping force. Because it is flexible, it is only suitable for vertical tapping with a large space. Silk

Embodiment Construction

[0018] figure 1 It is a structural schematic diagram of the invention, figure 2 The perspective view of the invention, as shown in the figure: The flexible tap chuck structure assembly of the invention includes a main handle 1, a jacket 2 with a cylindrical clamping body, and a tap 5 that cooperates with the jacket 2. In the jacket 2 A stopper for the tap 5 is arranged on it, and the stopper can move radially and axially along the clamping body. The radial movement of the stopper is used to pull out the tap 5 from the clamping body or fix it after clamping, and the axial movement of the stopper is used to make the tap 5 expand and contract with the advancing spindle when it contacts the workpiece distance.

[0019] In this embodiment, the jacket 2 is provided with an axially deformable elastic member 11; the elastic member can also be arranged at the clamping end of the tap 5 to solve the problem of excessive contact.

[0020] In this embodiment, the stopper includes a tog...

Abstract

The invention discloses a flexible screw tap chuck structure assembly, and the flexible screw tap chuck structure assembly comprises a main handle and a clamp cover with a cylindrical clamping body, wherein the clamp cover is provided with a retainer for a screw tap, and the retainer can be moved along the clamping body in radial and axial directions; the flexible screw tap chuck structure assembly has the advantages of simple structure, small volume and strong clamping force, after the assembly is clamped, the screw tap has low beat and a certain adjustment and can be quickly and effectively located, and the service life of the screw tap and the tapping effect can be quickly and effectively improved, thus the flexible screw tap chuck structure assembly is especially applicable for small-space tapping in the non-vertical direction.

Description

technical field [0001] The invention relates to a tap chuck which is installed on the main shaft of a working machine while maintaining the tap and performs internal thread processing with the rotation of the main shaft, in particular to a flexible tap chuck structural assembly. Background technique [0002] The existing tap chucks are divided into two categories: fixed clamping and flexible clamping. Their advantages are that the fixed tap chuck has simple structure, small size, strong clamping force, and small tap jump after clamping. It is suitable for various Tapping in the same direction; the flexible tap chuck can automatically center the tap through clearance adjustment, and protect the tap and thread from damage by adjusting the stop force; their disadvantages are that the fixed tap chuck cannot adjust the tapping force , and the tapping center cannot be adjusted, which may easily cause damage to the tap or thread; the flexible tap chuck has a complex structure, larg...
