Technical field
The utility model belongs to field of mechanical technique, relates to a kind of drill chuck, and particularly a kind of loading and unloading are drill chuck efficiently.
Background technology
Existing drill chuck, such as hand fastening drill clutch and spanner drill chuck, all comprise drill body, inclination jaw, with the nut of jaw threaded engagement, by rotating nut, make jaw clamp or the drilling tool that gets loose.The rear portion of drill body is provided with the connecting hole that cooperates with motor shaft, and general employing of motor shaft and connecting hole is threaded, and therefore, drill chuck is installed and when getting loose drilling tool, need be expended suitable time rotating nut usually.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of loading and unloading simple in structure drill chuck efficiently, and this drill chuck has and is connected characteristics more efficiently with motor output shaft.
The purpose of this utility model can realize by following technical proposal: a kind of loading and unloading are drill chuck efficiently, comprise drill body, end at drill body is provided with the jaw that is used for clamping drilling bit, it is characterized in that, the other end at drill body is provided with installed part, offer the connecting hole of the motor output shaft that is used to peg graft on the described installed part, also be provided with several spacing holes on the sidewall of described installed part, outside installed part, be removably fixed with fixed cover, also being provided with in the spacing hole of installed part can be with the spacing limited block in this spacing hole of motor output shaft, also be arranged with elastomer on the described limited block, described elastomer one end acts on the fixed cover, and the other end acts on the limited block.
This loads and unloads efficiently, and the jaw of drill body one end of drill chuck is used for clamping drill bit, the installed part of the other end of drill body is used for installing motor output shaft, the work of motor just can drive the rotation of this drill chuck like this, drives the rotation of drill bit again, thereby realizes the work such as boring of drill bit.With offer several fixing holes on the motor output shaft that this drill chuck cooperates, when needs cooperate this drill chuck with motor output shaft, motor output shaft is inserted in the connecting hole of installed part, limited block is pressed in the spacing hole of installed part, the rotary electric machine output shaft, at this moment, limited block is under the elastomer effect, make limited block fall in the fixing hole of motor shaft, motor output shaft forms transmission torsion with limited block and cooperates, thereby finishes the fitting operation of this drill chuck quickly and easily.When need with drill chuck when motor output shaft is dismantled, motor output shaft is pulled outwardly, limited block forces elastomer compression limited block to fall in the spacing hole of installed part under the effect of external force, thereby makes that this drill chuck is disassembled from motor output quickly and easily.
Efficiently in the drill chuck, described elastomer is a spring in above-mentioned loading and unloading.
Efficiently in the drill chuck, described fixed cover is fixed on outside the installed part by interference fit in above-mentioned loading and unloading.
Efficiently in the drill chuck, the quantity of described spacing hole is four in above-mentioned loading and unloading.
Compared with prior art, this loads and unloads efficiently, and drill chuck can make this drill chuck and motor output shaft realize being connected fast and dismantling by limited block, syndeton is simple, and the torsion transmission of motor output shaft and drill chuck simultaneously is more reliable, can improve the cutting strength of drill chuck.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a structure explosive view of the present utility model.
Fig. 3 is the cutaway view of Fig. 1 along A-A.
Among the figure, 1, drill body; 2, installed part; 21, connecting hole; 22, spacing hole; 3, jaw; 4, fixed cover; 5, limited block; 6, spring; 7, motor output shaft; 71, fixing hole.
The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As Fig. 1, Fig. 2 and shown in Figure 3, this loads and unloads drill chuck efficiently, comprise drill body 1, end at drill body 1 is provided with the jaw 3 that is used for clamping drilling bit, is provided with installed part 2 at the other end of drill body 1, offers the connecting hole 21 of the output shaft 7 that is used to peg graft on the described installed part 2, also be provided with several spacing holes 22 on the sidewall of described installed part 2, be removably fixed with fixed cover 4 outside installed part 2, particularly, fixed cover 4 is fixed on outside the installed part 2 by interference fit.Be to offer several quantity and above-mentioned spacing hole 22 corresponding to fixing holes 71 on output shaft 7, also being provided with in the spacing hole 22 of installed part 2 can be with output shaft 7 spacing limited block 5 in this spacing hole 22.Also be arranged with spring 6 on limited block 5, described spring 6 one ends act on the fixed cover 4, and the other end acts on the shoulder block of limited block 5.By the effect of spring 6, make being located in above-mentioned fixing hole 71 and the spacing hole 22 that limited block 5 can be more stable.
In the present embodiment, the quantity of described spacing hole 22 is four, and the quantity of limited block 5 and spring 6 also all is to be four.
This loads and unloads efficiently, and the operation principle of drill chuck is such: the jaw 3 of an end of drill body 1 is used for clamping drill bit, the installed part 2 of the other end of drill body 1 is used for installing output shaft 7, the work of motor just can drive the rotation of this drill chuck like this, drive the rotation of drill bit again, thereby realize the work such as boring of drill bit.When needs cooperate this drill chuck with output shaft 7, output shaft 7 is inserted in the connecting hole 21 of installed part 2, limited block 5 is pressed in the spacing hole 22 of installed part 2, rotary output axis 7, at this moment, limited block 5 makes limited block 5 fall in the fixing hole 71 of motor shaft under spring 6 effects, output shaft 7 forms transmission torsion with limited block 5 and cooperates, thereby finishes the fitting operation of this drill chuck quickly and easily.When need with drill chuck when output shaft 7 is dismantled, output shaft 7 is pulled outwardly, limited block 5 forces spring 6 compression limited blocks 5 to fall in the spacing hole 22 of installed part 2 under the effect of external force, thereby makes that this drill chuck is disassembled from motor output quickly and easily.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used 1, drill body morely; 2, installed part; 21, connecting hole; 22, spacing hole; 3, jaw; 4, fixed cover; 5, limited block; 6, spring; 7, motor output shaft; 71, term such as fixing hole, but do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
