Abstract

The invention discloses a flexible tapping fixture. The flexible tapping fixture comprises a fixed handle, a sleeve, a cardan joint and a screw tap clamping handle, wherein the lower end of the fixed handle is connected with the upper end of the sleeve, the cardan joint is installed inside the sleeve, the upper end of the cardan joint is connected with the top wall of the sleeve, and the lower end of the cardan joint exceeds the open end of the sleeve and is connected with the screw tap clamping handle. Due to the fact that the sleeve and the cardan joint are installed between the fixed handle and the screw tap clamping handle, and the cardan joint is installed inside the sleeve, during the operation of tapping, under the condition of the center of the screw tap is deviated, the screw tap manufacturing is defect or the feed of a machine tool is insufficient, the precision between the fixed handle and the screw tap clamping handle can be adjusted by the cardan joint, the precision of the tapping can be improved and the service life of the screw tap can be prolonged.

Description

technical field [0001] The invention relates to the technology of a tapping jig, in particular to a flexible tapping jig. Background technique [0002] Existing tapping jigs include a fixed handle and a tap holding handle, and the fixed handle is rigidly connected to the tap holding handle. When performing tapping operations, the mounting part of the fixing handle is fixed on the rotating shaft of the drilling machine, and the tap is installed on the In the tap holding handle, the rotating shaft of the drilling machine rotates, which drives the fixed handle and the tap holding handle to rotate, and then drives the tap to rotate to tap the hole on the workpiece. [0003] Existing tapping fixtures have high requirements on the accuracy and rigidity of the tapping system. In the actual tapping process, when the center of the tap deviates, the clamping force of the tapping fixture is insufficient, the processing thread is deep, the manufacturing defect of the tap or the machine ...
