Description

Powerful machine tool handle

The present invention relates to a machine tool part, in particular to a machine tool handle.

Saving energy and reducing carbon emissions has become the focus of industrial development in countries around the world. Some companies even require energy-saving and carbon-reduction certification for the machines and equipment they use. As a result, the design of more and more machines and equipment is also moving towards energy conservation. The tool and machine industry is no exception. Therefore, how to make the operation of tools and machines meet the requirements of energy conservation and carbon reduction is the direction that the tool and machine industry is vigorously developing.

Therefore, the object of the present invention is to provide a power-generating machine tool handle that can improve at least one disadvantage of the prior art.

Therefore, the power-generating machine tool handle of the present invention is suitable for being installed on a machine tool and for mounting a tool. The machine tool handle comprises a handle body which can be driven and rotatably mounted on the machine tool and for mounting the tool, and a power generation mechanism mounted on the handle body.

The power generation mechanism includes a bearing module sleeved and fixed outside the handle body, a rotor module sleeved and fixed outside the handle body, a stator module sleeved and fixed outside the bearing module and sleeved outside the rotor module, and a resistance structure unit arranged on the stator module. The stator module can rotate relative to the rotor module via the bearing module. One of the rotor module and the stator module can generate a magnetic field, and the other of the rotor module and the stator module can generate electricity in response to the magnetic field.

When the handle body is driven to rotate and drive the sleeve-fixed bearing module and the rotor module to rotate, the bearing module will drive the stator module to rotate, and the resistance structure unit will be driven to rotate by the stator module, and generate wind resistance with the surrounding air, thereby driving the stator module and the rotor module to generate a rotation speed difference.

The effect of the present invention is that, through the structural design of installing the power generation mechanism on the tool handle body, when the tool tool is driven by the tool handle body to rotate to process the workpiece, the rotation speed difference between the rotor module and the stator module can be used to generate electricity, thereby converting part of the kinetic energy into electrical energy for reuse, thereby achieving the purpose of energy saving and carbon reduction.

Before the present invention is described in detail, it should be noted that similar components are represented by the same reference numerals in the following description.

Referring to Figs. 1, 2 and 3, a first embodiment of a power-generating machine tool handle 200 of the present invention is suitable for being installed on a machine tool (not shown) and can be used for mounting a tool (not shown). The machine tool handle 200 can be driven to rotate by the machine tool, and drive the tool to rotate to perform processing on a workpiece. The processing includes, for example but not limited to, drilling, milling and grinding. The machine tool handle 200 includes a handle body 3 for mounting on the machine tool and mounting the tool, and a power generation mechanism 4 sleeved and mounted on the outside of the handle body 3.

It must be explained first that in the following embodiments, the machine tool handle 200 is upright mounted on the machine tool for use. However, in practice, the setting direction of the machine tool handle 200 is not limited to this.

The tool handle body 3 has a connection section 31 extending up and down and used for detachably mounting and connecting to the machine tool, and a mounting section 32 extending coaxially downward from the connection section 31 and used for the tool to be inserted and connected upward. Since the tool handle body 3 can be detachably mounted on the machine tool and can be used for mounting the tool, both are existing technologies with many types and are not the focus of the present invention, so they are not described in detail.

The power generation mechanism 4 includes a rotor module 41 that can be driven to rotate and is sleeved and fixed outside the installation section 32 and can generate magnetic electricity, a bearing module 42 that is sleeved and fixed outside the installation section 32, a stator module 43 that is sleeved and installed outside the bearing module 42 and is sleeved outside the rotor module 41, and a resistance structure unit 44 that is arranged on the stator module 43 and is used to generate wind resistance.

The rotor module 41 includes a cylinder 411 sleeved and fixed outside the mounting section 32, and a coil assembly 412 disposed on the outer periphery of the cylinder 411 and extending along the periphery of the cylinder 411. The coil assembly 412 can be used to generate electricity by sensing the change of the magnetic field generated by the stator module 43. Since the coil assembly 412 can generate electricity by sensing magnetic field is an existing technology and has many types, it will not be described in detail.

The stator module 43 includes a housing 431 that is sleeved and fixed on the outside of the bearing module 42 and sleeved on the outside of the rotor module 41, and a magnet unit 432 that is installed and fixed on the inner circumference of the housing 431 and surrounds the rotor module 41 at intervals. The magnet unit 432 has a plurality of magnets 433 that are arranged at intervals along the inner circumference of the housing 431 and cooperate to generate the magnetic field required for the rotor module 41 to generate magnetically induced electricity.

In the first embodiment, only one bearing module 42 for the outer shell 431 to be mounted on is provided in the section of the mounting section 32 located above the rotor module 41. However, in practice, in other embodiments of the present invention, the number of the bearing modules 42 can be increased according to the axial extension length of the outer shell 431, for example but not limited to adding another bearing module 42, and the bearing modules 42 are respectively located on the axial sides of the rotor module 41, so that the outer shell 431 is mounted on the bearing modules 42.

The resistance structure unit 44 includes a plurality of resistance structures 441 spaced along the periphery of the outer shell 431 and protruding from the outer peripheral surface of the outer shell 431. When the resistance structures 441 are driven to rotate by the outer shell 431, they interact with the surrounding air to cooperate to produce the wind resistance effect that interferes with the rotation of the outer shell 431.

In this embodiment, the resistance structures 441 are plates extending vertically and radially protruding from the outer peripheral surface of the outer shell 431. However, in practice, in other embodiments of the present invention, the resistance structures 441 may also be curved plates or other structures that can be used to generate the wind resistance effect.

When the handle body 3 is driven by the machine tool to drive the rotor module 41 and the bearing module 42 to rotate synchronously, since the stator module 43 is sleeved on the bearing module 42, the bearing module 42 drives the stator module 43 to rotate through friction and rotational inertia. However, because the stator module 43 is provided with the resistance structure unit 44, the wind resistance generated by the resistance structures 441 and the surrounding air will reversely offset part of the friction between the outer shell 431 and the bearing module 42, thereby causing the outer shell 431 to not rotate synchronously with the bearing module 42, resulting in a rotation speed difference between the outer shell 431 and the rotor module 41. Conversely, the magnets 433 installed in the outer shell 431 will generate a rotation speed difference with the coil assembly 412.

With this design, when the machine tool drives the tool handle 200 so that the tool handle 200 drives the tool to rotate to process the workpiece, the rotor module 41 rotates relative to the magnets 433 and senses the magnetic field of the magnets 433 to generate electricity.

During implementation, the power generated by the rotor module 41 can be stored in a power storage device (not shown), or the power generated by the rotor module 41 can be used to directly drive some low-power electronic components (not shown), such as but not limited to driving LED lights, light sensors or temperature sensors.

4 and 5 , a second embodiment of the power-generating machine tool handle 200 of the present invention differs from the first embodiment in the structural design of the power generation mechanism 4. For the convenience of explanation, only the differences between the embodiments will be described below.

In the second embodiment, the rotor module 41 includes a magnet unit 413 disposed on the outer peripheral surface of the mounting section 32 of the handle body 3. The magnet unit 413 has a plurality of magnets 414 arranged along the periphery of the mounting section 32.

The stator module 43 includes a housing 431 which is sleeved and fixed on the outside of the bearing module 42 and sleeved on the outside of the rotor module 41, and a coil assembly 434 which is arranged on the inner circumference of the housing 431 and surrounds the magnetic unit 413 at intervals.

When the handle body 3 is driven to rotate and drive the rotor module 41 and the bearing module 42 to rotate, the outer shell 431 of the stator module 43 will produce a rotation speed difference with the rotor module 41 due to the wind resistance generated by the resistance structure unit 44, so that the coil assembly 434 can sense the magnetic field of the relatively rotating magnet unit 413 and generate electricity.

Referring to FIG. 6 , when the above two embodiments are implemented, the resistance structure unit 44 can also be changed to be set on one of the top and bottom end surfaces of the outer shell 431, for example, arranged along the periphery of the bottom end of the outer shell 431 and protruding from the bottom end surface of the outer shell 431, and the resistance structures 441 can be designed to be curved sheets, or other shapes that can generate wind resistance. With this design, the wind resistance can also be generated when being driven to rotate.

However, since there are many types of the resistance structure unit 44 that is disposed on the outer circumference or end surface of the outer shell 431 and generates wind resistance during rotation, during implementation, the resistance structure unit 44 is not limited to the aspects disclosed in the embodiments.

In addition, it must be particularly pointed out that when the tool machine handle 200 of the present invention is installed in the tool machine for use, in addition to the wind resistance of the resistance structure unit 44, the magnets 433, 414 and the coil assemblies 412, 434 can produce a speed difference, and at the same time as the tool is cooled by spraying a cooling fluid (not shown) toward the tool, the cooling fluid is simultaneously sprayed toward the resistance structure unit 44, so as to drive the resistance structure unit 44 to drive the outer shell 431 to rotate in the opposite direction relative to the tool handle body 3, thereby causing the coil assemblies 412, 434 to rotate relative to the magnets 433, 414 to generate electricity by magnetic induction.

In addition, in the drawings of the above-mentioned embodiments, the coil components 412 and 434 shown in the drawings are only schematic, and the implementation is not limited to the drawings.

In summary, by installing the power generation mechanism 4 on the tool handle body 3, when the tool tool drives the tool handle body 3 and the tool to rotate to process the workpiece, the rotation speed difference between the rotor module 41 and the stator module 43 can be used to generate electricity, thereby converting part of the kinetic energy into electrical energy for reuse, thereby achieving the purpose of energy saving and carbon reduction. Therefore, the tool tool handle 200 of the present invention is indeed a very innovative creation that helps to save carbon and can indeed achieve the purpose of the present invention.

However, the above is only an embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the present patent.
