Abstract
The invention discloses the improvement on the spindle and tap connection structure of a tapping machine. The connection structure comprises a spindle and a tap, wherein the tap is movably and irrotationally plugged in the spindle. The structure also comprises an elastic sleeve having an axial drawing force and a radial fastening force, one end of the elastic sleeve is fastened and fixed on one end of the spindle, the other end of the elastic sleeve is fastened on the part, outside the spindle, of the tap, and the tapped end of the tap is exposed from the elastic sleeve. The improvement can effectively preventing threads from being damaged by the tap, reduce the radial size of the spindle and ensure a simple structure and easy assembly and disassembly.
Description
Technical field
The present invention relates to the syndeton of a kind of tapping machine axle and screw tap.
Background technology
The axle of general tapping machine and the syndeton of screw tap, its complex structure assembling inconvenience, again because when lifting device lifting axle, when axle drives the screw tap lifting again, make screw tap when promoting, destroy thread owing to the gap of gear exists, and this design feature of the syndeton of general axle and screw tap make the radial dimension of axle can't do little.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides the improved connection structure of a kind of tapping machine axle and screw tap, this structural improvement can make the axle radial dimension reduce, simple in structure, can also prevent effectively that thread is damaged.
The present invention for the technical scheme that solves its technical problem and adopt is:
The improved connection structure of a kind of tapping machine axle and screw tap, comprise axle and screw tap, screw tap activity spline inserts in the axle, also be provided with a resilient sleeve, this resilient sleeve has axial tensile force and tightening force radially, resilient sleeve one end banding is fixed in axle one end, the part of resilient sleeve other end banding outside screw tap is positioned at axle, and screw tap tapping end is exposed to outside the resilient sleeve, like this when lifting device lifting axle, when axle drives the screw tap lifting again, the axial tensile force of resilient sleeve can cushion lifting force, can not exist owing to the gap of gear to make screw tap destroy thread when promoting.
Further technical scheme of the present invention is:
The structure that screw tap activity spline inserts in the axle is: the section configuration that screw tap is positioned at the inner end of axle is a non-circular geometry, axle inside is provided with the hole that is complementary with this screw tap one end, and screw tap inserts in the hole, and spline radially between axle and the screw tap axially can be slided relatively like this.
Resilient sleeve is a spring.
The invention has the beneficial effects as follows: because screw tap activity spline inserts in the axle, be provided with a resilient sleeve again, this resilient sleeve has axial tensile force and tightening force radially, resilient sleeve one end banding is fixed in axle one end, the part of resilient sleeve other end banding outside screw tap is positioned at axle, and screw tap tapping end is exposed to outside the resilient sleeve, like this when lifting device drives axle and screw tap lifting, the axial tensile force of resilient sleeve can cushion lifting force, can not use screw tap to promote and the destruction thread, again because this design feature makes that the radial dimension of axle is reduced, and this example is simple in structure, is easy to assembling and dismounting.

The specific embodiment
Embodiment: the improved connection structure of a kind of tapping machine axle and screw tap, comprise axle 1 and screw tap 2, screw tap activity spline inserts in the axle, also be provided with a resilient sleeve 3, this resilient sleeve has axial tensile force and tightening force radially, resilient sleeve one end banding is fixed in axle one end, the part of resilient sleeve other end banding outside screw tap is positioned at axle, and screw tap tapping end 6 is exposed to outside the resilient sleeve, like this when lifting device lifting axle, when axle drove the screw tap lifting again, the axial tensile force of resilient sleeve can cushion lifting force, can not exist owing to the gap of gear make screw tap destroy thread when promoting.
The structure that screw tap activity spline inserts in the axle is: the section configuration that screw tap is positioned at the inner end 4 of axle is a non-circular geometry, axle inside is provided with the hole 5 that is complementary with this screw tap one end, and screw tap inserts in the hole, and spline radially between axle and the screw tap axially can be slided relatively like this.
Resilient sleeve is a spring.
