Abstract

Provided is an electric socket wrench being capable of using electric power. The electric socket wrench is provided with two semicircular steel plates in special shapes, a shim is arranged on the steel plates, a hollow circle is arranged in the middle of the two halves of the shim, the shim is screwed up via a bolt but is not compacted on a worm, and the gap between the shim and the worm is about 1/10mm to allow the worm to rotate in the shim. A worm gear is pushed by a rotating worm screw which is provided with bearing stands at the two ends, each end of the worm screw is provided with a low pressure bearing to fix the worm to prevent the wrench provided from being damaged when the pushing force is too strong to push the worm gear rotating forwardly and reversely. the middle of the worm gear pushed by the worm is provided with a through shaft from the left to right, both sides of the through hole are provided with bearings, the excircle of each bearing is fixed on a housing, one end of the through shaft is in the housing of the steel plate, and a sleeve plug arranged at the other end of the through shaft extends out of the housing for replacing the sleeve in different sizes. The other end of the worm is provided with a recessed cross square head which is connected to a motor shaft equipped with a protruding cross square head, a bearing is arranged at the connection part, and a miniature motor capable of controlling forward and reverse rotation is fixed on the rack of the bearing. The screw-up and loose of the nut are controlled by the forward and reverse rotation of the motor. The wrench provided can be directly manually used without the need for conversion when the wrench is out of power.

Description

Electric socket wrench

Affiliated technical field:

The utility model relates to a kind ofly, tighten or unload and loosen the screw a little, the spanner, the especially electric socket wrench that can raise the efficiency that cooperate sleeve to use.

Background technology:

At present, well-known box spanner is manual tightening or unload and loosen the screw a little entirely, and the slow efficient of speed is too low, electronic box spanner market, also do not see, had only pneumatic wind big gun, and connected the hammer band and twist nut, only adapt in open occasion, also must join small air compressor could use, supporting costliness, incompatibility space-constrained screw tightening or unload pine.

Summary of the invention:

In order to overcome the nut setter spanner, on to unload screw slow, the time-consuming again deficiency of requiring great effort, the utility model is designed a kind of electronic box spanner, cooperate to load onto sleeve, can on unload screw.

The technical scheme of being taked that the utility model is dealt with problems is: with shell frame two fans, load onto shim, fixedly make by the shim fixing hole through the shim anchoring filament about gap two decimillimeters of shim and worm screw, worm screw is rotated in shim.The worm gear that the worm screw of rotation promotes, the worm screw on worm screw silk two limits is thick slightly, it is pedestal, two little bearing fixing worm screws of pressure are housed, and the worm gear centre that is promoted by worm screw is an axis, and bearing is equipped with on axis two limits, bearing top circle is fixed on the shell, one of axis does not protrude outer cover of steel plate, and it is square title sleeve plug that shell is protruded in the other end, in order to changing the sleeve of different sizes.The other end of worm screw is that a recessed cross is connected with protruding crosshead motor shaft, adorns a bearing in the junction, can conveniently control the micro-machine that is just reversing on fixing on the frame of bearing.

The beneficial effects of the utility model are: the utility model cooperates sleeve, rotary nut that can be rapidly and efficiently, and can when having electricity, need not change direct use, also can when repair, take apart easily and assemble.

Description of drawings:

Fig. 1 is the electric wrench external form, and Fig. 2 is the electric wrench profile, and Fig. 3 is shim and worm gear front enlarged drawing.Among the figure: 1 shell frame .2 sleeve plug .3 shim anchoring filament .4 motor .5 motor fixing frame .6 worm gear .7 bearing .8 shim fixing hole .9 pressure bearing .10 worm screw silk .11 shim .12 worm screw .13 worm-wheel shaft .14 bearing bracket stand.

The specific embodiment:

In three accompanying drawings, 1 shell frame is two fans, is by 11 shims and 8 shim fixing holes and the synthetic complete electric wrench shell of 3 shim anchoring filaments.The 4 small-sized motors that just reversing are connected with 12 worm screws wheel by cross, and are clipped by 11 shims through 5 motor fixing frames, about round young waiter in a wineshop or an inn's decimillimeter of 12 worm screw diameters and 11 shims, help worm screw rotation in the middle of shim.The worm screw at 10 worm screw silk two slightly slightly is a pedestal, and 9 pressure bearings are installed on 10 worm screw silk two pedestals.The outrigger of 9 pressure bearings is 11 shims.In the middle of 6 worm gears is that an axon has 13 worm-wheel shafts on one side, Yi Bian be 2 sleeve plugs, 2 sleeve plugs, lining circle foreign side, the inside and 13 worm-wheel shafts are 7 bearing internal frames, 7 bearings are in the shell at 14 bearing outriggers.Principle is that 4 motors rotate to drive 12 worm screws, the rotation of 12 worm screws, 6 worm gears are given in transmission, 6 worm gears and 2 sleeve plugs are one, from but 2 sleeves sleeve beyond the Great Wall rotate, the rotation screw cap reaches the purpose of electronic parbuckle screw.

Claims

1. electric socket wrench, be that two fans are removable, be by motor transmission worm screw, be transferred to worm gear again with sleeve plug one, make the electric socket wrench of sleeve plug rotation, it is characterized in that: micro-machine (4) is connected with worm screw (12), worm screw promote worm gear (6) and with the sleeve plug (2) of worm gear one.

2. electric socket wrench according to claim 1 is characterized in that: described worm screw has the worm screw silk, and two ends of worm screw silk have pedestal, and every end is equipped with a pressure bearing.

3. electric socket wrench according to claim 1 is characterized in that: in the middle of the described worm gear is the axis of one, also is the internal frame as bearing.
