Abstract
The invention discloses an electric screwing tool which comprises a sleeve port, a sleeve shaft, a harmonic gear outer gear ring, a transmission shaft, a driving motor and a shell. The driving device is arranged in the shell. The shell is provided with a control switch for controlling the driving motor. The harmonic gear outer gear ring is connected with the driving motor through the transmission shaft. The sleeve shaft is connected with the harmonic gear outer gear ring through a bearing. The sleeve shaft is sleeved with a spring and sleeved with the sleeve port. The spring is connected with the sleeve shaft and the sleeve port. In this way, the electric screwing tool can rapidly unscrew a rust nut, does not need to be manually aligned to the nut, and is high in efficiency, small in size, large in moment of force and applicable to be carried by a vehicle as a standby.
Description
Technical field
The present invention relates to mechanical engineering field, particularly relate to a kind of electronic stubborn tool.
Background technology
Engineering goods always go out some either large or small problems in the middle of long-term use, but some nuts can become rusty because of Long-Time Service and die in an accident or political incident to back out in maintenance process.Adopt the method lengthening actuation arm, there is force difficulty, dynamics is inadequate, dangerous high drawback in the past, according to the mode of wind big gun nutting, there is quality large, handicapped problem.And because six rib directions of each nut are difficult to be consistent, so usually twist tool to use front necessary first manual-alignment nut, the waste plenty of time.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of electronic stubborn tool, can turn on rust nut cap fast, and without the need to manual-alignment nut, efficiency is high, small, and moment is large, is applicable to vehicle-mounted for subsequent use.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of electronic stubborn tool, comprising: sleeve-port, quill, harmonic gear external toothing, power transmission shaft, drive motors and shell; Described drive motors is arranged in described shell, and shell is provided with the gauge tap controlling described drive motors; Described harmonic gear external toothing is connected with described drive motors by described power transmission shaft; Described quill is connected with described harmonic gear external toothing by bearing; In described quill, cover has spring, and sleeve-port is enclosed within described quill, and spring connects described quill and sleeve-port.
Preferably, be provided with draw-in groove inside described sleeve-port, described quill is provided with the fixture block corresponding with draw-in groove, and fixture block is stuck in draw-in groove and limits the described sleeve-port synchronous axial system of described quill rotation drive.
Preferably, described quill and described bearing form wave producer, and the indentation of described bearing outer ring is meshed with the inside indentation of harmonic gear external toothing, composition harmonic gear drive mechanism.
Preferably, the gauge tap of described drive motors is divided into two-stage, and two-step evolution switch controls slowly running of drive motors and high-speed rotation respectively.
Preferably, described shell is provided with main handle and assist handle.
The invention has the beneficial effects as follows: the present invention can turn on rust nut cap fast, and without the need to manual-alignment nut, efficiency is high, small, moment is large, is applicable to vehicle-mounted for subsequent use.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1 to Fig. 3, the embodiment of the present invention comprises:
A kind of electronic stubborn tool, comprising: sleeve-port 1, quill 3, harmonic gear external toothing 5, power transmission shaft 6, drive motors 7 and shell 8; Described drive motors 7 is arranged in described shell 8, and shell 8 is provided with the gauge tap 9 controlling described drive motors 7, and gauge tap 9 can be convenient to the manipulation to drive motors 7; Described harmonic gear external toothing 5 is connected with described drive motors 7 by described power transmission shaft 6; Described quill 3 is connected with described harmonic gear external toothing 5 by bearing 4; In described quill 3, cover has spring 2, and sleeve-port 1 is enclosed within described quill 3, and spring 2 connects described sleeve-port 1 and quill 3, and spring 2 entangles nut after sleeve-port 1 can be made to aim at nut fast.Be provided with draw-in groove inside described sleeve-port 1, described quill 3 is provided with the fixture block corresponding with draw-in groove, and fixture block is stuck in draw-in groove and limits described sleeve-port 1 synchronous axial system of described quill 3 rotation drive.Described quill 3 forms wave producer with described bearing 4, the described indentation of bearing 4 outer ring is meshed with the inside indentation of harmonic gear external toothing 5, composition harmonic gear drive mechanism, harmonic gear drive mechanism can make little moment be converted to high-torque, makes motor only need input little moment and can realize turning on of nut.The gauge tap of described drive motors 7 is divided into two-stage, and two-step evolution switch controls slowly running of drive motors 7 and high-speed rotation respectively, slowly runs and can control the rapid alignment of nut, and high-speed rotation can realize turning on fast of nut.Described shell 8 is provided with main handle 10 and assist handle 11, and a kind of electronic stubborn tool conveniently held by main handle 10, and turn on after sleeve-port 1 is carried out rapid alignment facing to nut, assist handle 11 is turned on after better can carrying out aligning nut.
During use, press the one-level switch of gauge tap 9, drive motors 7 slowly runs, and makes sleeve-port 1 be in rotation status; Be held by main handle 10 by sleeve-port 1 facing to the nut needing to turn on, sleeve-port 1 because being in rotation status and under the effect of spring 2, rapid alignment nut; Press the secondary switch of gauge tap 9 again, drive motors 7 high-speed rotation; Under the effect of harmonic gear drive mechanism, when completing a rotation period, sleeve-port 1 moment be applied on nut is the i(gearratio of drive motors 7 exerted forces square) doubly, and very large (the single-stage 50-300 of the gear range of harmonic gear, twin-stage 3000-60000), the division of the number of teeth is depended in the setting of gearratio, thus drive motors 7 export little moment can by rust dead nut turn on, so high-speed rotation is for slowly running.
The present invention can turn on rust nut cap fast, and without the need to manual-alignment nut, efficiency is high, small, and moment is large, is applicable to vehicle-mounted for subsequent use.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
