[0015] Beneficial effects:

[0016] This utility model relates to a magnetically controllable electromagnetic tool holder structure.

[0017] 1. By controlling the magnetic strength and direction of the electromagnet, when the magnetic field direction is aligned with the neodymium magnet, a downward thrust is generated. This is measured by a pressure diaphragm sensor pressed under the neodymium magnet, achieving closed-loop precise control of the blade pressure. When the magnetic field direction is opposite to the neodymium magnet, an upward attraction is generated, achieving the blade lifting action. This utilizes the magnetic field of the neodymium magnet itself and the controllable magnetic strength and direction of the electromagnet, thus eliminating the need for a spring and fully utilizing the internal guide rail constraints of the tool holder, resulting in a simple and compact structure. Performance-wise, it also offers faster response and avoids the problem of spring aging.

[0018] 2. By setting up a pressure diaphragm sensor and placing it directly between the neodymium magnet and the connecting frame, electromagnetic pressure can be measured more directly, more accurately, and more simply. Attached Figure Description

[0030] Reference Figure 1-4 This utility model provides a magnetically controllable electromagnetic tool holder structure, including a mounting frame 1, on which a control mechanism is provided; the control mechanism includes a fixed plate 101, a slide rail 102, a connecting frame 103, a plurality of guide rail sliders 104, an electromagnet 108, a pressure diaphragm sensor 106, and a neodymium magnet 107. The fixed plate 101 is fixedly installed on one side of the mounting frame 1, the slide rail 102 is fixedly installed on one side of the fixed plate 101, the plurality of guide rail sliders 104 are fixedly installed on one side of the connecting frame 103, the guide rail sliders 104 are slidably installed in the slide rail 102, the electromagnet 108 is fixedly installed on one side of the mounting frame 1, the pressure diaphragm sensor 106 is fixedly installed on the top of the connecting frame 103, and the neodymium magnet 107 is fixedly installed on the top of the pressure diaphragm sensor 106;

[0031] In this embodiment, by controlling the magnetic strength and direction of the electromagnet 108, when the magnetic field direction is consistent with that of the neodymium magnet 107, a downward thrust is generated. This thrust is measured by the pressure membrane sensor 106 pressing under the neodymium magnet 107, achieving closed-loop precise control of the blade pressure. When the magnetic field direction is opposite to that of the neodymium magnet 107, an upward attraction is generated, achieving the blade lifting action. This utilizes the magnetic field of the neodymium magnet 107 itself and the controllable magnetic strength and direction of the electromagnet 108, thus eliminating the need for a spring and fully utilizing the internal guide rail constraints of the blade holder, resulting in a simple and compact structure. Performance-wise, the response is faster, while avoiding the problem of spring aging.

[0032] Optionally, the connecting frame 103 is slidably mounted in the slide rail 102 on one side of the mounting frame 1 by a plurality of guide rail sliders 104, so that the connecting frame 103 can move smoothly on one side of the mounting frame 1.

[0033] In one embodiment, a baffle 105 is fixedly installed on one side of the connecting frame 103. The baffle 105 is located on one side of the guide rail slider 104. The mounting frame 1 is inverted L-shaped, and the electromagnet 108 is disposed on the top of one side of the mounting frame 1. The output end of the electromagnet 108 is opposite to the corresponding neodymium magnet 107. The connecting frame 103 is Z-shaped, and an installation port is opened at the bottom of the connecting frame 103. The tool holder 109 is fixedly installed in the installation port by bolts.

[0034] In this embodiment, the electromagnet 108 is paired with a dedicated electronic drive board to output a PWM signal based on the value detected by the pressure diaphragm sensor 106 to control the direction and intensity of the electromagnet's magnetic field. The drive board processes the measurement results using an algorithm, thereby achieving a linear pressure output that is more in line with actual needs than relying on a spring for pressure control, making the processing process smoother.

[0035] In this example, by setting a neodymium magnet 107, the neodymium magnet 107 can be a sheet-shaped neodymium magnet 107. The neodymium magnet 107 has extremely high magnetic energy product and remanence, and can generate a stronger magnetic field than other magnets in the same volume, which can better drive the connecting frame 103 to lift and lower.

[0036] In this example, when the tool holder 109 encounters the material and can no longer descend, the pressure diaphragm sensor 106 can accurately measure the electromagnetic thrust, thereby knowing the pressure of the tool on the material.

[0037] In this example, the pressure membrane sensor 106 can be a thin-film pressure sensor. By setting the pressure membrane sensor 106 and placing it directly between the neodymium magnet 107 and the connecting frame 103, electromagnetic pressure can be measured more directly, more accurately, and more simply.

[0038] In one embodiment, the top of the mounting bracket 1 is provided with a mounting groove 2, which is located on both sides of the electromagnet 108. A fixing frame 201 is fixedly installed on the wall of the mounting groove 2. A mounting frame 204 is slidably installed on one side of the fixing frame 201. A notch 206 is provided on one side of the mounting frame 204. A plurality of threaded holes 205 are provided on both sides of the mounting frame 204. The mounting frame 204 is fixedly installed on the fixing frame 201 through the threaded holes 205 and screws.

[0039] In this embodiment, a fixing frame 201 is provided for mounting the mounting frame 204. The mounting frame 204 is detachable, making it convenient to replace the gasket 208 inside.

[0040] In one embodiment, a motor 202 is fixedly installed on one side of the fixed frame 201. The output end of the motor 202 extends into the interior of the fixed frame 201. A first gear 203 is fixedly installed on the output end of the motor 202. The first gear 203 is located inside a notch 206 on one side of the mounting frame 204. A rotating disk 207 is provided inside the mounting frame 204. Rotating components 209 are fixedly installed at the center of both ends of the rotating disk 207. The rotating components 209 are rotatably installed on both sides of the inner wall of the mounting frame 204. A second gear 210 is fixedly installed at one end of the rotating component 209 on one side of the rotating disk 207. A plurality of shims 208 are fixedly installed on the outer wall of the rotating disk 207. The second gear 210 extends into the notch 206 on one side of the mounting frame 204. The second gear 210 meshes with the first gear 203.

[0041] In this embodiment, after the mounting frame 204 is inserted into the fixing frame 201, the first gear 203 meshes with the second gear 210. The motor 202 can be a servo motor. When the motor 202 starts, it drives the first gear 203 to rotate. The rotation of the first gear 203 drives the second gear 210 to rotate, thereby driving the rotating disk 207 to rotate. This facilitates the replacement of the gasket 208 and reduces the impact of gasket 208 deformation on the protective effect.

[0042] In this example, the bottom of the gasket 208 is lower than the output end of the electromagnet 108. When the connecting frame 103 rises, it can prevent the neodymium magnet 107 from directly impacting the electromagnet 108, thus protecting the electromagnet 108.

[0043] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
