Abstract
The utility model relates to a DC electric screwdriver. When in dismounting screws, with low work efficiency and high labor-intensity, traditional wrenches or screwdrivers are very inconvenient, moreover, the use of electric screwdrivers of the prior art, most of which are using the AC power, can be restricted in the places without the AC power; the utility model comprises a shell, a motor arranged in the shell, and a workpiece sleeve connected with a motor shaft; the shell is provided with a switch; the utility model is characterized in that the motor is a DC motor; a battery which is connected with the motor is arranged in the shell; the switch which is connected with the battery in series is a two-way switch; the electric screwdriver of the utility model can work anywhere in anytime, and the utility model is portable, easy to be used, and effectively solves the defects of the use of the prior products of prior art.
Description
[technical field]
The utility model relates to a kind of electric tool of dismounting screw, especially a kind of direct current drive screwdriver.
[background technology]
In equipment installation or maintenance process, run into the situation that screws or unscrew screw through regular meeting.For the bigger screw of some diameters, need spend the more time during with shfting wrench or box spanner dismounting; For some tension or dead screws that seriously becomes rusty of twisting, need to beat just and can achieve the goal while twisting.Use traditional screwdriver or spanner very inconvenient, inefficiency, labour intensity is big.Existing electric screw driver uses AC power mostly, and in the place of AC-less power, use is restricted.
[summary of the invention]
The technical assignment of technical problem to be solved in the utility model and proposition is the defective that overcomes prior art, and a kind of direct current drive screwdriver easy to carry, time saving and energy saving, chargeable and the energy speed governing that uses is provided.
The technical solution of the utility model is such: the direct current drive screwdriver, comprise housing, place the motor in the housing and be connected workpiece sleeve on the motor shaft, housing is provided with switch, it is characterized in that described motor is a direct current generator, be provided with the battery that is connected with motor in the housing, the switch of connecting with battery is a two-way switch.Battery is made dc source, dc motor work, and electric screw is criticized can work whenever and wherever possible, is not subjected to the restriction of workplace and power supply type, is convenient to carry, easy to use, has solved the problem that manual dismounting screw brings.
Described direct current drive screwdriver, battery are two group storage batteries, are located at respectively in the afterbody and handle of housing, according to actual needs, can change the joint number of battery.Housing head is provided with the speed governing knob, and a push rod is spirally connected in the speed governing knob; Be provided with planetary gears between motor and the workpiece sleeve, planetary gears comprises that the left and right gear ring that is positioned at retainer plate reaches and its planet gear meshed, left side gear ring connects the workpiece sleeve, be provided with pole between left side gear ring and the retainer plate, this pole is conflicted on push rod and right gear ring, is provided with stage clip between right gear ring and the motor.Rotation speed governing knob can make push rod be moved, because the interaction of right gear ring in the pole that cooperates with push rod and stage clip and the planetary gears, make right gear ring and the change of planetary mesh degree in the planetary gears, thereby the work sleeve rotating speed that is connected with planetary gears is changed, reached the purpose of speed governing.
The direct current drive screwdriver of described adjustable speed, housing are built-in with a charging plug that is connected with battery, and during charging, charging plug connects the alternating current-direct current transformer; Housing is provided with charging indicator light.
The direct current drive screwdriver of described adjustable speed is characterized in that the end face of motor is provided with the stage clip holder, in order to fixing stage clip.
Time-consuming, the deficiencies such as labour intensity big, inefficiency of effort when the utility model had overcome in the past manually the dismounting screw, solved the shortcoming that the AC electrical screwdriver is subjected to workplace and power limitations, have time saving and energy saving, can speed governing, change output torque, use advantage easy to carry and that can charge.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
[specific embodiment]
As shown in Figure 1, housing 1 and handle 7 that butt joint forms are connected as a single entity, and are provided with charging plug 17, two group storage batteries 6, two-way switch 5, direct current generator 2 and planetary gears in the housing 1, and the head of housing 1 is provided with a speed governing knob 8.Speed governing knob 8 is connected with housing 1 by connector 16, and connector 16 and housing 1 are for being threaded, and a push rod 9 is spirally connected in the speed governing knob 8.Planetary gears comprises left and right gear ring and and its planet gear meshed 13 that is positioned at retainer plate 10.Left side gear ring 11 socket workpiece sleeves 4 according to the screw of various different sizes, can be changed the work sleeve that matches, planetary gear 13 in the right gear ring 12 and motor shaft 3 engagements.Be provided with three poles that cooperate with push rod 14 between a left side gear ring 11 and the retainer plate 10, these poles are conflicted on push rod 9 and right gear ring 12, be provided with three stage clips 15 between right gear ring 12 and the motor 2, stage clip 15 places in the stage clip holder 19 that is located at the motor front end face.Two-way switch 5 is connected with motor 2, battery 6 respectively by lead, and two-way switch 5 has positive and negative two grades, the rotating of corresponding motor respectively, and the rotating of motor can make screw means or unscrew.Housing 1 is provided with the charging indicator light 18 that is connected in series with charging plug 17.
When the dismounting screw, work jacket casing that will be identical with the nut diameter and covers screw on left gear ring.Pressing change-over switch rotates electrode, the planetary gear that motor shaft drives in the right gear ring rotates, because of planetary gear that is positioned at right gear ring and the planetary gear engagement that is positioned at left gear ring, so left gear ring also rotates thereupon, thereby the work sleeve of making rotates, with the screw dismounting.
When, the tension of twisting big to diameter or the dead screw that seriously becomes rusty carry out dismounting, need carry out speed governing to the output shaft that electric screw is criticized, clockwise direction rotation speed governing knob, push rod moves right, the bar that is butted between push rod and the right gear ring forces right gear ring to move right, and stage clip is compressed.Because moving right of right gear ring can cause being positioned at the planetary gear of right gear ring and the mesh degree of right gear ring changes, thereby the rotating speed of work sleeve is changed, reached the purpose that changes work sleeve moment of torsion.Opposite spin speed governing knob, push rod is moved to the left, and the elastic force of stage clip makes right gear ring to left movement, and pole also thereupon near the push rod place, equally also can be played the purpose of change work sleeve moment of torsion.
