Abstract
The invention provides a simple drilling machine tapping fixture. The simple drilling machine tapping fixture comprises a Morse taper sleeve and a tapping screw tap; a clamping groove is formed in the Morse taper sleeve; the clamping groove is matched with the tapping screw tap; a frictional layer is arranged on the inner wall of the clamping groove. The simple drilling machine tapping fixture is simple and reasonable in structure and capable of effectively improving the problem of low precision of the manual tapping product; meanwhile, due to the adjustable taper matching of the inner and outer sleeves, the screw tap can be in close fit with the fixture and the safety in the machining process can be ensured.
Description
Technical field
The present invention relates to a kind of auxiliary equipment of machining, be specifically related to a kind of simple and easy drilling machine tapping tool.
Background technology
Drilling machine refers to the lathe mainly using drill bit machining hole on workpiece.Usual bit is main motion, and drill bit moves axially as feed motion.Drilling machine structure is simple, and machining accuracy is relatively low, can holes drilled through, blind hole, changes special tool, can expand, spot-facing, reams or carries out the processing such as tapping.In process, workpiece is motionless, allows cutter move, and by center cutter alignment hole center, and makes cutter rotate (main motion).The feature of drilling machine is that workpiece maintains static, and cutter rotates.
Tapping processing is a kind of processing mode of drilling machine, and tapping is exactly adopt a kind of dedicated tool of machining internal thread in the circular hole of machine-shaping, rotates in the axial direction, has screw tap to cut the machining mode depicting internal thread on the surface at circular hole.Tapping processing is divided into manually processing and motor-driven processing two kinds of modes, in the prior art, for the boring of some aperture and the degree of depth, owing to not having suitable tapping tool, therefore, manually can only carry out tapping, thus reduce production efficiency and Product Precision.
Summary of the invention
For solving the above-mentioned problems in the prior art, the invention provides a kind of security high, simple and reasonable simple and easy drilling machine tapping tool.
Technique effect of the present invention is achieved through the following technical solutions:
A kind of simple and easy drilling machine tapping tool, comprise mohs bush and screw tap for tapping, in mohs bush sleeve, be provided with draw-in groove, described draw-in groove matches with screw tap for tapping, and described draw-in groove inwall is provided with frictional layer.
Wherein, also comprise bolt, described bolt is arranged in mohs bush sleeve wall, is threaded with described sleeve wall.
Concrete, the tapping of drilling machine frock in the present invention is connected with drilling machine by mohs bush, draw-in groove and screw tap square toes transfer of torque.Frictional layer can make screw tap and draw-in groove compact siro spinning technology, prevent screw tap loose or dislocation in draw-in groove, meanwhile, for ensureing the security of screw tap further, sleeve wall is provided with screwed hole, described screwed hole is provided with bolt, in frock process, props up screw tap by bolt head, screw tap is further reinforced, ensure the concentricity of screw tap and drill press spindle, prevent screw tap from coming off, security incident occurs.
The invention has the beneficial effects as follows:
The present invention is simple and reasonable, effectively can improve the low problem of hand tapping Product Precision, meanwhile, regulates inner sleeve and the adjustable taper fit regulating overcoat, screw tap and frock can be made to closely cooperate, guarantee the security of process.
Accompanying drawing explanation
Fig. 1 is a kind of tapping of drilling machine tool structure schematic diagram disclosed by the invention.
Detailed description of the invention
As shown in Figure 1, a kind of simple and easy drilling machine tapping tool, comprise mohs bush 1 and screw tap for tapping (not shown), in mohs bush sleeve 2, be provided with draw-in groove 3, described draw-in groove 3 matches with screw tap for tapping, and described draw-in groove 3 inwall is provided with frictional layer 5.Also comprise bolt 4, described bolt 4 is arranged in mohs bush sleeve wall, is threaded with described sleeve wall.
Concrete, the tapping of drilling machine frock in the present invention is connected with drilling machine by mohs bush 1, draw-in groove 3 and screw tap square toes transfer of torque.Frictional layer 5 can make screw tap and draw-in groove 3 compact siro spinning technology, prevent screw tap loose or dislocation in draw-in groove 3, meanwhile, for ensureing the security of screw tap further, sleeve 2 wall is provided with screwed hole, described screwed hole is provided with bolt 4, in frock process, props up screw tap by bolt 4, screw tap is further reinforced, ensure the concentricity of screw tap and drill press spindle, prevent screw tap from coming off, security incident occurs.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
