Abstract

The invention relates to the technical field of machining, in particular to a shaft radial floating tapping mechanism. The shaft radial floating tapping mechanism comprises a screw tap and a screw tapfixing mechanism, a floating connecting rod and a connecting rod sleeve piece, wherein the screw tap fixing mechanism is used for installing the screw tap, the screw tap fixing mechanism is fixedly connected with the floating connecting rod, a blind hole is formed in the connecting rod sleeve piece, and the floating connecting rod is inserted into the blind hole of the connecting rod sleeve piece; a first elastic part is arranged between the end part, far away from the screw tap, of the floating connecting rod and the connecting rod sleeve piece; the connecting rod sleeve piece is provided with a through pin hole in the radial direction, a through hole is formed in the floating connecting rod in the radial direction, the length and the width of the through hole are both larger than the diameter of the pin hole, a transmission pin penetrates through the pin hole and the through hole, and a limiting mechanism used for fixing the position of the transmission pin is arranged on the floating connecting rod; and the outer diameter of the floating connecting rod is smaller than the inner diameter of the blind hole, and a plurality of second elastic pieces are arranged between the floating rod piece and the inner wall of the blind hole. According to the shaft radial floating tapping mechanism, the length and the width of the through hole are both larger than the diameter of the pin hole, the axial displacement and the radial displacement of the floating connecting rod and the connecting rod sleeve can be realized, and axial and radial floating can be realized.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an axial radial floating tapping mechanism. Background technique [0002] In the manufacturing industry, the use of tap tapping for internal thread processing is temporarily unavoidable. At present, two forms of rigid tapping and floating tapping are used in the existing technology. The rigid tapping cycle synchronizes the rotation and feed of the spindle to match the specific required thread pitch. Since the feed into the hole is synchronized, theoretically an integral tap holder with any tension compression cannot be used. However, the problem in this aspect in actual production is that machine tools (especially special-purpose machine tools, hydraulic pressure tools, etc.) tapping machines, multi-spindle tapping, etc.) cannot be precisely matched to the specific tap pitch being used. There is always a slight difference between the thread processed by the machin...
