Abstract
The utility model relates to a split rotating and driving device, which aims at solving the issues that an electric motor and an operating main part are arranged into an entity in the prior art so that the volume is large and an electric brush and a gear must be provided so the device is easily worn. The power main body of the device is a rectangular box, while a switch is arranged on the power main body; the electric motor is arranged in the power main body and one end of a soft shaft sleeve is connected with the output end of the power main body, while the other end of the shaft sleeve is connected with the input end of an operating main body; and a soft shaft core is arranged in the soft shaft sleeve, whose one end is connected with the output shaft of the electric motor via a joint and the other end is connected with a shaft lever that is arranged in the operating main body; the other end of the shaft lever is connected with a universal joint that is arranged in the operating main body, while the universal joint is connected with a working head. The device has small volume and light weight and is handy for operating and is completely unlimited by the spatial position of the operating part and the entire weight, so the device can better meet the need of field service, also the utility model is safe and reliable, low in power consumption as well as noise and durable.
Description
(1) technical field
The utility model belongs to electric tool, is specially adapted to angle grinding machine, lapping machine, electric screwdriver, electric wrench etc.
(2) background technique
In the prior art, angle grinding machine, lapping machine, electric screwdriver, electric wrench etc., all with micro motor as power source, motor, operating grip and working head are fitted together in the lump.The instrument of this structure uses very heavy, owing to limit by spatial position, operating position and overall weight, thereby the motor in it can only be done very for a short time, so just make that motor torque is restricted, can not full load satisfy on-the-spot usage requirement, cause burn-down of electric motor, even cause human casualty accident.Can only adopt " series excitation formula " micromachine owing to being limited to motor weight, so just necessary adapted " brush ", and brush is very easily consumable accessories, in use frequently replacing.When brush wear was arrived to a certain degree, spark rises from all around, and opening circuit and bad connection of motor circuit often takes place for this reason, causes accident to take place frequently, and was very dangerous.In addition, motor output shaft drives a pair of umbrella gear transmission, and this just produces thorn ear noise greatly inevitably, not only causes environmental pollution, and two umbrella teeth are meshing with each other, and very easily wearing and tearing, thereby gear usually " are shaved clearly ", are not durable very much.
(3) summary of the invention
To be solved in the utility model is exactly existing electric tool, motor is installed with operation body one, the volume heaviness, motor is not durable, and needs problems such as adapted brush and gear very easily wear and tear, and a kind of novel structure that provides, operate light, safe and reliable, low in energy consumption, noise is little, long-lived split type rotating driving device.
Technical solution of the present utility model is to realize like this.Split type rotating driving device, comprise motor, switch, axostylus axostyle, power body etc., the power body is a rectangular box, switch is installed on the power body, motor is installed in the power body, one end of flexible shaft protecting and the output terminal of power body link, the other end of flexible shaft protecting links with the input end of operation body, the flexible axle core places in the flexible shaft protecting, one end of flexible axle core links by the output shaft of zygote and motor, and the other end links with being contained in the intrinsic axostylus axostyle of operation, and the operation body is a cavity, the other end of axostylus axostyle links with being contained in the intrinsic universal joint of operation, and the other end of universal joint links with the working head that is located at operation body output terminal.
The output shaft of described motor can link by a zygote and flexible axle core, also can link by a plurality of zygotes and flexible axle core.
Described working head can be the working head of different geometries.
Described flexible shaft protecting can adopt wire interweave in length and breadth in the injecting glue body, also can adopt steel wire spiral forming high strength nonmetallic material.
Described flexible axle core can adopt metallic material, also can adopt nonmetallic material.
Described flexible axle core can adopt the steel ball tandem junction box-like.
Described universal joint can adopt metallic material, also can adopt the spiral whole coiling of metallic material to form.
Owing to adopted above structure, make that this device volume is little, in light weight, operation is light, be not subjected to the restriction of spatial position, operating position and overall weight fully, therefore can satisfy well on-the-spot usage requirement and safe and reliable, low in energy consumption, noise is little, durable in use.

Fig. 2 is the A-A sectional view of Fig. 1.
(5) embodiment
As shown in Figure 1, the split type rotating driving device of the utility model is by switch 1, motor 2, power body 3, zygote 4, flexible shaft protecting 5, flexible axle core 6, operation body 7, axostylus axostyle 8, universal joint 9, working head 10 is formed, power body 3 is a rectangular box, switch 1 is installed in the position that power body 3 is convenient to handle, motor 2 is contained in the power body 3, one end of flexible shaft protecting 5 and the output terminal of power body 3 link, the other end of flexible shaft protecting 5 links with the input end of operation body 7, injecting glue body in flexible shaft protecting 5 employing wires interweave in length and breadth, flexible axle core 6 adopts metal flexible axle core, place in the flexible shaft protecting 5, keep certain clearance (as shown in Figure 2) between flexible shaft protecting 5 and the flexible axle core 6.One end of flexible axle core 6 links by the output shaft of zygote 4 with motor 2, and the running torque of motor 2 reaches axostylus axostyle 8 by zygote 4, flexible axle core 6.Operation body 7 is a cavity, axostylus axostyle 8 is contained in the operation body 7, the other end of one end and flexible axle core 6 links, and the other end links with an end that is contained in the universal joint 9 in the operation body 7, and the other end of universal joint 9 links with the working head 10 that is located at operation body 7 output terminals.Universal joint 9 adopts the spiral whole coiling of metallic material to form.
During work, master cock 1, starting electrical machinery 2 drives 6 rotations of flexible axle core by zygote 4.Simultaneously, axostylus axostyle 8 is rotation synchronously also, meanwhile by rotating force and the working head 10 crossing 90 degree synchronously rotations of universal joint 9 with axostylus axostyle 8.
