Abstract
The utility model discloses an adjustable moment electric drill, screwdriver crossover sub, this adapter can be used to screwdriver and electric drill switching for twist and move the screw. Its technical scheme main points are that this crossover sub includes: the reduction gears has input part and efferent, and wherein the input part is connected fixedly with the drill bit of electric drill to input high rotational speed, and export the slow -speed of revolution from the efferent, fixture is fixed with the efferent of reduction gears for the clamping screw sword. Fixture can rotate along with the efferent of reduction gears. So just, can drive the wrong screw that moves of screwdriver. The application range of electric drill has been expanded.
Description
Technical field
The utility model relates to changing-over head, and more particularly, it relates to a kind of adjustable force moment electric drill, screwdriver crossover sub.
Background technology
The advantages such as electric drill is widely used in repairs profession, and electric drill is generally used for wall drilling, efficient with it, reliable obtain the favor of decoration worker.Sometimes, people to wish electric drill, with in other respects, to be such as used for turning screw.And electric drill itself directly can not be used for the turn of the screw, the function that realize the turn of the screw needs by adapter.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of adjustable force moment electric drill, screwdriver crossover sub, and motor drill bit can be connected with screwdriver by this adapter, thus achieves the function with electric drill the turn of the screw.
For achieving the above object, the utility model provides following technical scheme:
A kind of adjustable force moment electric drill, screwdriver crossover sub, comprising:
Reducing gear, has input part and efferent, and wherein the drill bit of input part and electric drill is connected and fixed, and to input high rotating speed, and exports the slow-speed of revolution from efferent;
Clamping device, fixes with the efferent of reducing gear, for clamping screw cutter.
Further, reducing gear is planet wheel decelerator, and the drill bit of its driving shaft and electric drill is connected and fixed, and its driven shaft and clamping device are fixed.
Further, clamping device is scroll chuck, and the driven shaft of its disk body and planet wheel decelerator is fixed.
Further, adjustable force moment electric drill, screwdriver crossover sub also comprise shaft coupling, and shaft coupling is located between planet wheel decelerator and scroll chuck, and its driving shaft is connected with the driven shaft of planet wheel decelerator, and the disk body of its driven shaft and scroll chuck is fixed.
Further, shaft coupling is adjustable spring pressure type moment shaft coupling.
Compared with prior art, the utility model has the advantages that: motor drill bit can be connected with screwdriver by the utility model, and make the rotating speed of rotating speed lower than electric drill of screwdriver, and the utility model is also provided with the mechanism of restriction rotating torque, screwdriver can be avoided to be twisted off.

Detailed description of the invention
With reference to Fig. 1, a kind of adjustable force moment electric drill, screwdriver crossover sub, comprise connector 5.Connector 5 is for being connected and fixed the drill bit of crossover sub and electric drill, and housing 1 inside is provided with reducing gear, and housing 1 bottom is clamping device, for the handle of clamping screw cutter, as preferably, this clamping device is scroll chuck 2, and scroll chuck 2 is made up of chuck body, movable jaw.On scroll chuck 2 below three claw targeting parts, screw thread is had to be meshed with the flat thread at the dish-shaped bevel gear back side, when rotating cone pinion with spanner by four square holes, dish pinion rotation, the flat thread at the back side drives three claws close or exit, in order to clamp the workpiece of different-diameter to center simultaneously.
With reference to Fig. 2, the reducing gear of housing 1 inside is planet wheel decelerator 4, and planet wheel decelerator is a kind of power transmission mechanism, comprise driving shaft and driven shaft, utilize the velocity transducer of gear, the winding number of motor is decelerated to desired winding number, and obtain the mechanism of larger torque.Gear wheel on the gears meshing output shaft that the number of teeth on planetary reduction gear power transmission shaft is few is to reach the object of deceleration.
In order to prevent when turning screwdriver, because moment of torsion crosses senior general, it twists off, and the utility model is also provided with shaft coupling, and shaft coupling comprises driving shaft and driven shaft, and two axles be used in connection different institutions make it jointly to rotate with transmitting torque.Shaft coupling itself has torque-limiting function, and when driving torque reaches the torque limiting of shaft coupling, shaft coupling dallies, thus avoids damaged screws cutter.Shaft coupling of the present utility model is located between planet wheel decelerator 4 and scroll chuck 2, and the driving shaft of described shaft coupling is connected with planet wheel decelerator 4 driven shaft, and driven shaft is connected with the disk body of scroll chuck 2.As preferably, this shaft coupling is adjustable spring pressure type moment shaft coupling 3.According to the length of different user demand regulating springs, the pressure (frictional force) between shaft coupling two rotation section can be changed, its moment of torsion changed like this.
Housing 1 is that on the driving shaft of planet wheel decelerator 4 and the driven shaft of adjustable spring pressure type moment shaft coupling 3, coaxial sleeve is provided with bearing 8, and housing 1 two ends offer circular hole, and the outer shroud of circular hole and bearing 8 is fixed with the fixed form of its internal mechanism.
What be worth explanation is a bit, the driving shaft of planet wheel decelerator 4 and the connected mode of motor drill bit are: on the driving shaft of planet wheel decelerator 4, be fixed with connector 5, with reference to Fig. 5, this connector 5 has inner chamber for cylindricity, and the shape of the shape of inner chamber and drill bit coincide (inwall is provided with helicla flute 9).Drill bit is aimed at inner chamber, and rotate forward drill bit and it can be made to proceed to inner chamber, and turn tighter and tighter, producing, departing from crossover sub when rotating backward for preventing drill bit from inner chamber, be provided with nut 6 at connector 5 outer wall, nut 6 is threaded with connector 5.Also have two regulating tanks 7 at connector 5 sidewall, the sidewall of connector 5 is divided into two parts, fastening nut 6, two parts sidewall of connector 5 is adjacent to each other, drill bit can be compressed, and prevents above-mentioned situation from occurring.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
