Technical field
The utility model relates to electric tool technical field, especially relates to a kind of miniature drill.
Background technology
Diameter is less than the drill bit of 3.175mm, is commonly referred to microbit, is interposed in by microbit on the chuck of micro electric machine drill during use, and drives its high-speed rotation to carry out the operations such as boring.The chuck of existing small-sized brill is owing to being that coaxial transmission is connected with motor shaft, and when dismounting chuck, chuck can rotate with motor shaft, and therefore its disassembling operations separately need join spanner, there is inconvenience.Traditional design transverse handle held by general small-sized brill, due to the qualitative disequilibrium of stable gravity center during duty, often causes drill bit to twist off and drill bit misalignment.Electric drill power supply adopts power line directly to inlay the mode of crimping with handle usually, and in work, power supply wire diameter and sheath stress make to keep balance gruelling in operation.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide the miniature drill of easy accessibility; Its complete machine axial arrangement, exempts horizontal handle, and center of gravity is unified, dynamic balance stability; Its DC (direct current) socket, power line is separated with the machine frame for movement, and effectively reduce power line stress, DC socket sliding axle, to linearly connected, can change with operating angle, makes this structure energy Spontaneous release power line yoke torsion.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of miniature drill, comprise casing, alignment circuit plate, high-speed electric expreess locomotive, central principal axis and high-speed bearing is provided with in casing, the front end of casing is provided with chuck and locking cap, the rear end of casing is provided with supply socket, central principal axis and high-speed electric expreess locomotive are in transmission connection and are set up in casing internal by high-speed bearing, chuck is fastenedly connected by locking cap and central principal axis, the front portion of described casing is provided with pilot hole, dismounting card column, spring and column sleeve is provided with successively from top to bottom in this pilot hole, spring housing is located in dismounting card column, and dismounting card column can be inserted in column sleeve up or down; The elastic force that dismounting card column overcomes spring moves down and offsets with described central principal axis.
Wherein, described casing comprises base and upper cover, and the front end of casing is provided with front end end cap, and the rear end of casing is provided with rear end end cap.
Further, be provided with the regulating wheel with described alignment circuit plate in described casing, it is outside that regulating wheel part stretches out in described upper cover.
Adopt after technique scheme, the utility model compared to the prior art advantageously:
Miniature drill described in the utility model, during dismounting chuck, press dismounting card column, the elastic force that dismounting card column overcomes spring moves down and closely offsets with the central principal axis in casing, prevents central principal axis from rotating, can facilitate the dismounting of chuck, after chuck dismounting completes, unclamp dismounting card column, dismounting card column resets under spring resistance effect, and miniature drill normally works.This miniature drill complete machine axial arrangement, exempts horizontal handle, and center of gravity is unified, dynamic balance stability; Its DC (direct current) socket, power line is separated with the machine frame for movement, and effectively reduce power line stress, DC socket sliding axle, to linearly connected, can change with operating angle, makes this structure energy Spontaneous release power line yoke torsion.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is decomposition texture schematic diagram of the present utility model.
In figure, 1: locking cap; 2: chuck; 3: front end end cap; 4: high-speed bearing; 5: central principal axis; 6: high-speed electric expreess locomotive; 7: base; 8: alignment circuit plate; 9: rear end end cap; 10: supply socket; 11: upper cover; 12: dismounting card column; 13: spring; 14: column sleeve.
Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, as shown in Figure 1.
A kind of miniature drill, comprise casing, casing is spliced by base 7 and upper cover 11, form the convenient handle shape gripped, the front end of casing is provided with front end end cap 3, and the rear end of casing is provided with rear end end cap 9, and the rear and front end of base 7 and upper cover 11 is respectively equipped with threaded joints, front end end cap 3 and rear end end cap 9 are threaded with the threaded joints of the rear and front end of base 7 and upper cover 11 respectively, and base 7 and upper cover 11 are locked.
Alignment circuit plate 8, high-speed electric expreess locomotive 6, central principal axis 5 and high-speed bearing 4 is provided with in casing, the front end of casing is provided with chuck 2 and locking cap 1, the rear end of casing is provided with supply socket 10, supply socket 10DC direct current jack, central principal axis 5 and high-speed electric expreess locomotive 6 are in transmission connection and are set up in casing internal by high-speed bearing 4, and chuck 2 is fastenedly connected by locking cap 1 and central principal axis 5.Be provided with the regulating wheel 16 with described alignment circuit plate 8 in casing, it is outside that regulating wheel 16 part stretches out in described upper cover 11, regulates the rotating speed of high-speed electric expreess locomotive 6 by stirring this regulating wheel 16.Motor is arranged on the position of forward a little end in casing, and alignment circuit plate 8 and regulating wheel 16 are arranged on the position of holding rearward of casing, and such structure can make housing center of gravity move forward, and grips comfortable, easy to operate.This miniature drill complete machine axial arrangement, exempts horizontal handle, and center of gravity is unified, dynamic balance stability; Its DC (direct current) socket, power line is separated with the machine frame for movement, and effectively reduce power line stress, DC socket sliding axle, to linearly connected, can change with operating angle, makes this structure energy Spontaneous release power line yoke torsion.
