The chuck comprises a chuck handle body and a tap jacket, wherein the chuck handle body and the tap jacket can be mutually embedded, the chuck handle body is provided with a screw-pitch compensating mechanism, and the tap jacket is provided with a safety overload-protecting mechanism. The overload-protecting type tap chuck disclosed by the utility model has a floating performance and can be automatically aligned, the thread machining quality is ensured, and the overload filament breakage is avoided; and the overload-protecting type tap chuck is rapid and convenient to replace various taps, is simple to operate and has a high work efficiency.
Description
Technical field
The utility model relates to the clamping mechanism on a kind of electric tool, specifically, is a kind of overload protection type tap chuck.
Background technology
Traditional tapping is to utilize artificial experience, if tapping on machine is difficult to by manually coming the perception moment of torsion, moment of torsion is once excessive fracture of wire easily, and traditional tapping system does not have overload protection function.
Summary of the invention
The purpose of this utility model is in order to overcome deficiency of the prior art, a kind of overload protection type tap chuck to be provided.
To achieve these goals, the technical solution of the utility model is:
A kind of overload protection type tap chuck, described tap chuck is by can chimeric mutually chuck handle body and tap chuck two parts forming; Have pitch compensation mechanism on the described chuck handle body, have safe overload protecting mechanism on the described tap chuck.
As further improvement of the utility model, described pitch compensation mechanism is a slide-bar that is movably connected, can be at axial or circular motion, and by the spring that links to each other and handle body steel ball as fixing.
As further improvement of the utility model, described safe overload protecting mechanism is a clutch that is movably connected, and is fixedly connected on coaxial body by chuck steel ball and disk spring.
As further improvement of the utility model, the endoporus circumference of the chimeric end of described chuck handle body is provided with the draw-in groove of opening; The body external peripheral surface of the chimeric end of described tap chuck also is provided with corresponding outstanding driving pawl, and described driving pawl can snap in the described draw-in groove when chimeric.
As further improvement of the utility model, the circumferential surface of described body is provided with groove, can be absorbed in the steel ball in the described tap chuck when chuck is chimeric.
The beneficial effect of the utility model overload protection type tap chuck shows as:
1, the installation of the connecting of chuck handle body and tap chuck, screw tap is quick-changing mechanism, the screw tap of fast changeable different size, thus saved man-hour greatly, improved efficient, and traditional tap holder is very inconvenient when loading and unloading, and loses time.
2, the handle body has pitch compensation mechanism, and chuck has safe overload protecting mechanism, in case disorderly button and screw tap fracture during tapping.
3, overload protection type tap chuck of the present utility model also has unsteady performance.During tapping, after screw tap touched the workpiece bottom outlet, the energy automatic capturing guaranteed screw processing quality.Good with respect to its flexility of traditional tapper mechanism, especially for blind hole, in the time of at the bottom of screw tap is attacked the hole; it can be because of the resistance at the bottom of the hole fracture of wire; but screw tap skids in wire taper sleeve, thereby protected screw tap effectively, and traditional tapping system does not have this function.
To sum up, overload protection type tap chuck of the present utility model is that Metal Cutting Machine Tools such as drilling machine, lathe, boring machine and machining center are attacked requisite machine tool when making screw thread, has advantages such as easy and simple to handle, safe and reliable, long service life.Overload protection type tap chuck of the present utility model can satisfy the tapping processing of all size screw thread by product specification with several different tap chucks, is that the ideal of tapping tool is selected.
Description of drawings
Fig. 1 is the structure cutaway view of the chuck handle body of overload protection type tap chuck.
Fig. 2 is the structure cutaway view of the tap chuck of overload protection type tap chuck.
Among the figure: 1 collet body, 2 handle body steel balls, 3 overcoats, 4 slide-bars, 5 steel balls, 6 movable sleeves, 7 draw-in grooves, 8 grooves, 9 bodies, 10 driving pawls, 11 shells, 12 chuck steel balls, 13 clutches, 14 disk springs, 15 positioning sleeves, 16 screw taps.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Overload protection type tap chuck of the present utility model comprise as shown in Figure 1 chuck handle body and tap chuck two parts as shown in Figure 2.The tail end of chuck handle body fixes with lathe for the collet body 1 of band Morse's taper; Overcoat 3 is fixedly connected with collet body 1; In succession the mutually movable sleeve 6 of a scalable motion of the other end of overcoat 3, the body 9 of tap chuck front end can embed in this movable sleeve 6, and is snapped in by the steel ball in the movable sleeve 65 in the surface groove 8 of this body 9, and the two is combined as a whole securely; Also be provided with the slide-bar 4 that links to each other with movable sleeve 6 in the overcoat 3, play the pitch compensation effect, can be at axial or circular motion, and by the spring that links to each other and handle body steel ball 2 as fixing.
In the tap chuck part, the periphery of body 9 is provided with outstanding driving pawl 10, and this driving pawl 10 can snap in when tap chuck and handle body are chimeric in the opening draw-in groove 7 in the movable sleeve 6, does the location and further reinforces circumferentially to connect and use.It is interior fixing that driving pawl 10 is arranged on the shell 11 of tap chuck, and fixing a clutch that is movably connected 13 together by chuck steel ball 12 and disk spring 14, plays safe overload protection and use.
During connection, the positioning sleeve 15 with the tap chuck front end advances earlier, allows screw tap 16 insert in the chuck square hole, unclamps positioning sleeve 15 again, and screw tap 16 is just locked; Carry out connecting of tap chuck and chuck handle body then: at first the movable sleeve 6 with handle body front end advances, allow body 9 insert in the handle body opening, make driving pawl 10 aim at the draw-in groove 7 of opening, unclamp movable sleeve 6 then, make tap chuck be locked in securely in the chuck handle body.
At last, it should be noted that above what enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and a lot of distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
