Abstract
The utility model relates to an inserting-in type drill chuck which comprises a drill body, clamping jaws, a nut and a nut tooth sleeve. The three clamping jaws are arranged in three equally-divided oblique holes of the drill body respectively. The nut is arranged in a nut groove of the drill body. The nut and threads of the clamping jaws form a thread transmission mechanism. The nut tooth sleeve is fixedly connected with the nut. An extending inserting-in body is arranged on the back portion of the drill body. The extending inserting-in body is a step cylinder body with the diameter being gradually increased. A lower cylinder body is a bearing table with the small diameter. An upper cylinder body is a bearing table with the large diameter. A middle cylinder body is provided with a gear key groove. Three outer circles, two bearings of an electric drill and a gear are connected in a matched mode, the extending length of the drill chuck is shortened, and then the length of the whole electric drill is shortened. The inserting-in type drill chuck is simple and reasonable in structure, the drill chuck is connected with the electric drill in a matched mode, the connecting size is short and small, operation and using are convenient, and the inserting-in type drill chuck is ideal.
Description
Technical field
The utility model relates to drilling attachment in a kind of hardware & tools and machine tool, specifically a kind of plug-in type drill chuck matching with the working-spindle of electric drill or pneumatic drill.
Background technology
The front end of existing electric hand drill has a thread spindle or taper shaft, connects drill chuck.Its weak point is, drill chuck is directly exposed to outside, and electric drill adds drill chuck, and volume is very large, is not suitable with portable carrying, deposits.And existing drill chuck is generally made up of drill body, jaw, gear ring, overcoat, three jaws are arranged on respectively in three decile inclined holes of drill body, gear ring is arranged in the gear ring groove of drill body, the screw thread of gear ring and jaw forms thread transmission, overcoat is fixedly connected with gear ring, and there are screwed hole or taper hole in drill body rear portion.While installing and using, the power transmission shaft of the power equipments such as the screwed hole at drill body rear portion or taper hole and electric hand drill is connected, and power transmission shaft drives drill body to drive three-jaw and folded instrument synchronously to rotate while rotation.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, and drill body parts are few, be connected coordinate short and small, the easy for operation plug-in type drill chuck of volume with electric drill.
The technical scheme in the invention for solving the above technical problem is: a kind of plug-in type drill chuck, it comprises drill body, jaw, screw, screw tooth cover, three jaws are arranged on respectively in three decile inclined holes of drill body, screw is arranged in the screw groove of drill body, the screw thread of screw and jaw forms thread transmission, screw tooth cover is fixedly connected with screw, it is characterized in that: described drill body rear portion is provided with prolongation insertosome, described prolongation insertosome is that diameter becomes large ladder cylinder step by step, its underpart cylinder is the pedestal that diameter is less, upper cylinder is the pedestal that diameter is larger, mediate cylindrical is provided with gear keyway.
In prolongation insertosome mediate cylindrical described in the utility model, be also provided with a jump-ring slot.
The utility model drill body rear portion is provided with prolongation insertosome, which is provided with three cylinders that diameter is different.To the fine finishining of three cylinder cylindricals, utilize two bearings and a gear of these three cylindricals and electric drill to be connected.Electric drill has reduced by an axle, has saved parts, and drill chuck plug-in type connects, and has greatly shortened the extension elongation of drill chuck, and then has shortened the length of whole electric drill.Against existing technologies, the utility model is simple and reasonable, is connected the volume that is connected short and small, easy for operation with electric drill, is a kind of desirable plug-in type drill chuck.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is the utility model composition structural representation.
Fig. 2 is the structural representation of drill body in the utility model.
Fig. 3 is that the utility model inserts confined state schematic diagram.
Label in figure is: 1. drill body, 2. jaw, 3. screw, 4. screw tooth cover, 11. pedestals, 12. gear keyways, 13. pedestals, 5. electric drill, 51. bearings, 52. gears, 53. bearings.
Detailed description of the invention
From Fig. 1, Fig. 2, can find out, a kind of plug-in type drill chuck, it comprises drill body 1, jaw 2, screw 3, screw tooth cover 4, three jaws 2 are arranged on respectively in three decile inclined holes of drill body 1, screw 3 is arranged in the screw groove of drill body 1, screw 3 forms thread transmission with the screw thread of jaw 2, and screw tooth cover 4 is fixedly connected with screw 3.The relation of said structure and coupled parts is same as the prior art, belongs to prior art, and this does not describe in detail.
Feature of the present utility model is: described drill body 1 rear portion is provided with the prolongation insertosome of integrative-structure, described prolongation insertosome is that diameter becomes large ladder cylinder step by step, its underpart cylinder is the pedestal 13 that diameter is less, upper cylinder is the pedestal 11 that diameter is larger, and mediate cylindrical is provided with gear keyway 12.
The cylindrical of drill body rear axle cushion cap 11 described in the utility model, mediate cylindrical and drill body rear axle cushion cap 13 needs fine finishining, so that and bearing and the bore precision-fit of electric drill.When concrete assembling, bearing 53 precision-fit on pedestal 11 and electric drill 5, bearing 51 precision-fit on pedestal 13 and electric drill, mediate cylindrical is in mating connection by being arranged on the gear 52 arranging in key in gear keyway 12 and electric drill.As shown in Figure 3.
In prolongation insertosome mediate cylindrical described in the utility model, be also provided with the jump-ring slot that a circumference arranges.Being used for placing jump ring uses.
The utility model drill body rear portion is provided with prolongation insertosome, which is provided with three cylinders that diameter is different.To the fine finishining of three cylinder cylindricals.When use, extend insertosome part and be arranged in the gear-box of electric drill, utilize two bearings and a gear of these three cylindricals and electric drill to be connected.Electric drill has reduced by an axle, has saved parts, and drill chuck plug-in type connects, and has greatly shortened the extension elongation of drill chuck, and then has shortened the length of whole electric drill.The utility model is simple and reasonable, is connected the volume that is connected short and small, easy for operation with electric drill, makes electric drill can be deep into more narrow space work, can lightly in the situation that of narrow space, use flexibly.
