Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a drive device for rotating tools and implements, and more specifically, it applies the torque of the output shaft of a motor to various rotary tools and implements through a flexible shaft. It is a drive device for rotary tools and tools that can transmit information and rotate them at high speeds, or rotate them at low speeds with large torque, and also allows for one-touch attachment and detachment of rotary tools, implements, etc. between motors and flexible shafts, and between flexible shafts and rotary tools. This invention relates to a drive device for rotating tools and tools that can be easily operated.

[Conventional technology]

As is well known, various rotating tools and implements are used when, for example, maintaining or cleaning automobiles. Among these rotary tools, rotary tools such as vacuum cleaners and polishers have conventionally been automatically driven to rotate using the torque of an electric motor or the like. However, many rotary tools such as screwdrivers and nut trenches are rotated manually. Therefore, a large force is required to rotate it, and there is also the problem that it takes a long time to work. Therefore, in recent years, for example, in repair shops and the like, such rotary tools have been driven to rotate using the torque of an electric motor or compressed air.

[Problem that the invention attempts to solve]

If the rotary tool is driven using power in this manner, there is an advantage that a large force is not required and the work can be completed in a short time.

However, when an independent drive mechanism is attached to each rotary tool or tool used, the following problems or problems arise that need to be solved. That is, (a) the individual rotary tools and implements become larger. Accordingly
(b) Requires a large space for storage. Again (ha)
The manufacturing cost per unit of rotating tools and tools becomes high. Therefore, it is considered that a single motor can rotate various rotary tools and implements, but since the required rotational speed differs depending on the rotary tool or implement by simply extracting the torque of the motor, it is possible to In some cases, it may not be possible to perform rotational drive according to the

The present invention has been developed in view of the above points, and its purpose is to be able to selectively extract the torque of the motor depending on the rotary tool or tool used. The motor can drive various rotary tools and tools, and each rotary tool and tool can be made small and compact, reducing manufacturing costs, and can be stored and stored in a small space. To provide a driving device for a rotary tool or tool, which can be easily carried, and especially can be easily assembled and disassembled with a single touch.

[Means for solving the problems] The present invention has the following technical means to achieve the above object. That is, to explain this using the reference numerals used in the attached drawings, the motor 6 fixed on the motor base 7, the reducer 9 fixed on the reducer base 8, and the motor 7
It consists of a flexible shaft 10 for transmitting the torque of the output shaft 11 of the reducer 9 and the output shaft 12 of the reducer 9 to the input shaft 17 of the rotary tool or tool, and connecting means 25 are provided on the motor base 6 and the reducer base 8, respectively. When the motor 7 and the reducer 9 are integrally connected by spline fitting, the motor base 6 and the reducer base 8 can be integrally connected. At the same time, above the motor base 6 and reducer base 8, there is a motor cover 41 with a handle 43 attached to the top surface, and a handle 43 also attached to the top surface.
A reducer cover 42 to which the gear reducer 4 is attached is removably arranged, so that the motor 7 and the reducer 9 can be covered when stored, and can be easily carried when carried. The output shaft 1 of the motor 7 is
1 and the output shaft 12 of the reducer 9 are respectively attached with a male part 13 of a one-touch joint, and one end part 14 of the flexible shaft can be connected to the male parts 13, 13 with one-touch. A female part 15 of a one-touch joint is attached to the other end 16, and the female part 15 of a one-touch joint is attached to the input shaft 17 of a rotary tool or tool. This is a drive device for a rotary tool or tool to which a male part 13 of a one-touch joint that can be attached is attached.

[Effect]

Since the present invention is comprised of the above-mentioned technical means, it is possible to selectively take out the torque of the motor 7 and rotate a rotary tool, tool, etc. at an optimum rotation speed. That is, when using a rotary tool such as a screwdriver 2 or a nut trench 3, the reducer 9 is connected to the output shaft 11 of the motor 7, and the output shaft 12 of the reducer 9 and the output shaft 4 of the rotary tools 2 and 3 are connected. It is used by connecting with a flexible shaft 10. Thereby, the rotation of the output shaft 11 of the motor can be decelerated, and the rotary tool can be rotated at a low speed and with a large torque.

Also, rotating tools 4, 5 such as vacuum cleaners and polishers
When using the motor, the output shaft 11 of the motor and the input shaft 4 of the rotary tool are directly connected by the flexible shaft 10. Thereby, the rotating tools 4 and 5 can be rotated at high speed. In this way, the torque generated on the output shaft 11 of the motor can be selectively extracted according to the rotary tool or implement to be used, and one motor 7 can rotate various rotary tools or implements. .

Although it is possible to rotate various rotary tools and implements with one motor 7 in this way, it is difficult to use it in practice if the attachment and detachment are complicated and time consuming. However, in this case, the male part 13 of the one-touch joint is attached to the connection part.
Since the female part 15 is attached, the male part 13
It is only necessary to fit and connect the female part 15 and the female part 15, and all the connections can be made with one touch.
In addition, since it is connected only when driving a rotary tool or implement and can be kept separate at all times, it is easy to store, store, and carry. Furthermore, motor base 6
Since a motor base cover 41 and a reducer cover 42 are removably disposed on the reducer base 8, the motor 7 and reducer 9 can be removed from these covers 41, 42 when stored.
The cover can be covered with a cover, and can be easily carried by gripping the handles 43 and 44 attached to the top surface of the cover.

In this embodiment, in order to drive the motor 7 with electricity from the car battery, a wire is connected to the end of the power line 39 on the front panel of the car. An example is shown in which an insertion plug 40 for insertion into the provided cigarette lighter insertion opening is attached.

Next, 41 is a motor cover that is detachably attached to the motor base 6, and 42 is a reducer cover that is also detachably attached to the reducer base 8. Handles 43 and 44 are attached to the upper surfaces of these covers 41 and 42, respectively, so that they can be gripped and carried when being carried. 45... is a snap lock provided to attach the motor base cover 41 and the reducer base cover 42 to the motor base 6 and the reducer base 8, respectively. The motor base cover 41 and the reducer cover 42 can be easily attached and detached. The snap lock 45 is also disposed between the motor base 6 and the reducer base 8, so that these bases 6 and 8 can be integrally connected. 4
Reference numerals 6 and 46 denote support legs disposed on the motor base 6, which can be pulled out laterally as shown by the dashed line in Fig. 4, and can be pulled out during use. Therefore, the area of the motor base 6 can be increased, and the motor 7 can be stably supported.

Next, the operation of the above embodiment will be explained.

Since the present invention is constructed as described above,
The torque of the output shaft 11 of the motor 7 can be transmitted to a rotary tool or implement through the flexible shaft 10 to drive the rotary tool, and the most suitable rotation can be set according to the rotary tool or implement to be used. It can be rotated by numbers.
That is, when driving the driver 2 and nut stretch 3 to rotate, low speed and large torque rotation is required. In such a case, the torque of the motor 7 is reduced by the reducer 9, converted into low-speed large torque, and extracted. When connecting the reducer 9, connect the spline-fitting male 24 to the output shaft 11 of the motor as described above.
The spline fitting male 24 is fitted to the spline fitting female 23 attached on the input shaft 22 of the reducer, and the motor base 6
This is done by integrally connecting the reducer base 8 and the reducer base 8. When connecting in this way, the male part 13 of the one-touch joint is attached to the output shaft 11 of the motor, and the female part 15 of the one-touch joint is attached to the spline fitting male 23. Therefore, the spline fitting male 24 can be easily attached to the output shaft 11 of the motor with a single touch. After connecting the reducer 9 to the motor 7 as described above, the output shaft 12 of the reducer and one end 14 of the flexible shaft are connected. This connection is the output shaft 12
The male part 13 of the one-touch joint is attached to the end of the flexible shaft, and the female part 15 of the one-touch joint is attached to one end of the flexible shaft. All you have to do is insert it as shown, and it can be done with one touch. Inside the flexible shaft 10,
Flexible transmission shaft 48 that can be bent freely but can transmit torque
is disposed while being covered by a protective cover 49, and the torque input from one end 14 is transmitted to the other end 1 by this flexible transmission shaft 48.
6. A male part 13 of a one-touch joint is attached to the other end 16, and if a driver 2, nut trench 3, etc. is connected to this male part 13, the driver 2, nut trench 3, etc. A rotary tool can be rotated at low rotation speed and high torque. Since the female part 15 of the one-touch joint is attached to the driver 2, nut trench 3, etc., the connection between the driver 2, nut trench 3, and the other end 16 of the flexible shaft can be made with one touch. Also, like this, flexible shaft 1
When attaching the screwdriver 2 and nut trench 3 to the screwdriver 0 and rotating them in the forward and reverse directions, the other end 16 of the flexible shaft 10 must be gripped, but this gripping is made easy. Therefore, if a grip cover 50 as shown in FIG. 2 is attached to the other end 16, it will be easier to grip.

In the above description, a case has been described in which a rotary tool such as a screwdriver 2 or a nut trench 3 is driven to rotate at a low speed and with a large torque. However, when a rotary tool such as a vacuum cleaner 4 or a polisher 5 is driven, high-speed rotation is required. In such a case, one end 14 of the flexible shaft may be directly connected to the output shaft 11 of the motor as shown in FIG. As mentioned above, for this connection, the male part 13 of the one-touch joint is attached to the output shaft 11 of the motor, and the male part 13 of the one-touch joint is attached to one end 1 of the flexible shaft.
Since the female part 15 of the one-touch joint is attached to the top of the connector 4, the male part 13 and the female part 15 can be connected with one touch by simply fitting them together.

In this way, the drive device 1 of the present invention is capable of rotationally driving various rotary tools and implements with one motor 7, and can vary the torque from low rotation to high torque to high torque at low rotations, depending on the requirements of the rotary tools and implements to be used. Alternatively, it can be selectively extracted by rotating at high speed. Also, between the output shaft 11 of the motor and the flexible shaft, between the output shaft 12 of the reducer and the flexible shaft, between the output shaft 11 of the motor and the input shaft 22 of the reducer,
Alternatively, there are various connection parts such as between flexible shafts and rotary tools, tools, etc., and since the male part 13 and female part 15 of one-touch joints are attached to all of these connection parts, they can be attached and detached with one touch. Easy to disassemble and reassemble. Moreover, since it can be disassembled and stored when not in use, it can be stored in a small storage space. When not in use, a motor base cover 41 and a reducer base cover 42 are placed on the motor base 6 and reducer base 8, respectively.
If the covers 41 and 42 are attached, the motor and reducer can be covered, and these covers 41 and 42 can be covered.
It can be easily carried by gripping the handles 43 and 44 attached to the top surface.

In this example, rotary tools and tools mainly used for car maintenance and cleaning are shown.
The present invention is not limited to automobile-related rotating tools and tools, but can be applied to other rotating tools and tools driven by torque.

Further, although the motor 7 is shown as a motor driven by an automobile battery, the objects and effects of the present invention can be similarly achieved even if other motors driven by, for example, 100V or 200V AC are used. Ru.

[Effect of idea]

As described in detail above, the present invention connects the flexible shaft 10 to the output shaft 11 of the motor 7 to directly take out the torque of the output shaft 11 of the motor 7, or connects the reducer 9 to the motor 7 to extract the torque from the output shaft 11 of the motor 7. The torque of the motor 7 can be selectively extracted according to the requirements of the rotary tool or tool used.
As a result, various rotary tools and tools with different required rotational speeds can be rotationally driven by one motor, and for this purpose, an independent rotational drive mechanism is provided for each rotary tool and tool. These rotary tools and tools can be made small and compact, reducing manufacturing costs, and can be disassembled to make them smaller, so they can be stored and stored in a small storage space. In addition, it is easy to carry, and in particular, the male part 13 and female part 15 of the one-touch joint are attached to the connection part, depending on the connection destination, so all the connection parts can be easily carried. It has various advantages, such as providing a drive device for rotary tools and tools that can be easily attached and detached with one touch, and easy to disassemble and assemble.
