Description

Technical Field

[0001] This utility model relates to the field of machine tool auxiliary products technology, specifically to a high-efficiency electromagnet chip collector for machine tools. Background Technology

[0002] When gears are machined on a gear hobbing machine, iron filings, commonly known as iron shavings, are produced. As an important gear machining tool, the gear hobbing machine works by using the meshing motion between a hob and a gear blank for continuous cutting. When the high-speed rotating hob encounters the slowly rotating workpiece, the numerous cutting edges on the hob, like a plane, peel away tiny layers of metal from the metal surface of the gear blank one by one. As this cut metal detaches from the workpiece, due to the plastic deformation of the material and the chip-coating effect of the cutting tool, it forms a continuous, uniquely shaped ribbon of chips. These chips typically exhibit a bright silver or bluish-brown oxidized color; they are curled and long, their shape very similar to wood shavings produced in woodworking, hence the name "iron shavings." The authorization announcement number CN219900521U discloses a compressor crankshaft spline gear hobbing machine. According to its instruction manual and drawings, the solution uses a rotating motor to drive the chuck holding the workpiece to rotate, thereby achieving multi-point machining of different workpieces. The cutting motor drives the hobbing wheel to rotate to perform cutting action.

[0003] However, the solution has certain limitations: 1. Currently, when cleaning up small iron filings splashed around machine tools, traditional handheld permanent magnets are often used for adsorption. This method requires secondary processing after adsorption, or even breaking the adsorbed iron filings apart by hand, which is obviously inconvenient to operate; 2. When using such strong magnets for adsorption, it is easy to cause scratches between the magnet and the hand, so there is also a safety hazard. Summary of the Invention

[0004] This invention addresses the aforementioned problems by providing a high-efficiency electromagnet iron chip collector for machine tools. This collector enables rapid adsorption and release of iron chips, thereby solving the problems of inconvenient cleaning, the need for secondary processing, and safety hazards associated with traditional permanent magnets.

[0005] The objective of this invention is achieved through the following technical solution: a high-efficiency electromagnet chip collector for machine tools, comprising an adsorption support, wherein the adsorption support has a hollow interior and an electromagnet body is provided at one end of the adsorption support, and a control component is provided at the other end of the adsorption support to control the electromagnet body to be energized or de-energized. The control component includes a circuit board and a power supply, and a wire on the electromagnet body for transmitting current passes through the interior of the adsorption support and is electrically connected to the circuit board.

[0006] Preferably, the control assembly further includes a control housing, one end of the adsorption support is detachably connected to the inside of the control housing, the inside of the control housing is provided with a housing slot for holding the circuit board, and the power supply is also located inside the control housing; This design integrates the circuit board and power supply into the control housing, preventing them from being struck, contaminated, or short-circuited by iron filings during operation, thus improving the reliability and lifespan of the device. The control housing forms the main gripping part of the device, and its cylindrical shape allows users to operate it steadily with one hand.

[0007] Preferably, the circuit board is also electrically connected to an indicator light, a charging interface, and a button. The power supply is also electrically connected to the circuit board via wires. The surface of the control housing is provided with a first clearance hole, a second clearance hole, and a third clearance hole. The indicator light, the charging interface, and the button pass through the first clearance hole, the second clearance hole, and the third clearance hole respectively to the outside. With this setting, the button is located on the surface of the housing, which can be easily reached by the user's thumb, realizing one-button switching of the magnetic force, and the operation process is extremely simple.

[0008] Preferably, the power source includes cylindrical batteries and a support base, with a lithium battery protection board connected in series between several cylindrical batteries and installed inside the support base, and the lithium battery protection board is electrically connected to the charging interface.

[0009] Preferably, the control housing has a mounting hole on the side surface away from the adsorption support and a U-shaped hook on the side wall of the adsorption support. The side wall of the support base is threaded to or glued to the mounting hole until the columnar battery on the support base extends into the interior of the control housing. This setup integrates the battery and lithium battery protection board onto the support base, forming a standalone standard power module that facilitates mass production, testing, and subsequent repair and replacement.

[0010] Preferably, the control housing has a first internal thread on the side near the adsorption support, and one end of the adsorption support is provided with a first external thread adapted to and connected to the first internal thread.

[0011] Preferably, one side surface of the electromagnet body is covered with an electromagnet support shell, and the electromagnet support shell extends toward one side of the adsorption support member with a second columnar boss. The second columnar boss has a second internal thread inside, and the other end of the adsorption support member is provided with a second external thread adapted to and connected to the second internal thread. The electromagnet support shell is also provided with a threaded hole and a wire avoidance hole. This design allows both ends of the adsorption support to be detached, thus dividing the device into three main modules: the control housing, the adsorption support, and the electromagnet. This modular design facilitates production.

[0012] Preferably, the electromagnet body, electromagnet support shell, adsorption support, and control shell all have circular cross-sectional shapes, and the length of the adsorption support is greater than the length of the electromagnet body, control shell, or electromagnet support shell. This setting allows the adsorption support to be longer than other components, enabling it to reach into narrow locations such as machine tool fixtures and workpiece gaps for cleaning.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Precise control of iron filings collection is achieved through the modular combination of the adsorption support, electromagnet body, and control components. The hollow design of the adsorption support allows wires to pass through, avoiding the risk of tangling or damage from external wiring. At the same time, the slender adsorption support allows it to reach into narrow areas for cleaning. Compared with traditional large magnetic adsorption devices, this slender columnar structure is low-cost and easy to use.

[0014] 2. This solution includes a control component consisting of a circuit board, power supply, and buttons. Users can control the power on and off of the electromagnet by simply pressing the button. After attracting iron filings, users only need to move the device above the waste bin and press the button again. The electromagnet will instantly lose power and magnetism, and all the attracted iron filings will fall off naturally and cleanly under the action of gravity, significantly improving efficiency. 3. An electromagnet body is used instead of a permanent magnet, and it is physically isolated from the control housing of the gripping part by a slender adsorption support. The electromagnet body is encased in the electromagnet support housing, and the entire device adopts a cylindrical shape design with no exposed sharp parts. Since the length of the adsorption support is greater than that of the electromagnet body and the control housing, when the user operates the control housing, a sufficient safe distance is maintained between the user's hand and the electromagnet body that is adsorbing iron filings. This fundamentally avoids the risk of the hand being scratched by the adsorbed sharp iron filings or pinched by the magnet. Attached Figure Description

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: like Figure 1 As shown, a high-efficiency electromagnet chip collector for machine tools includes an adsorption support 1. The adsorption support 1 has a hollow interior and an electromagnet body 2 is provided at one end of the adsorption support 1. The other end of the adsorption support 1 is provided with a control component 3 that can control the electromagnet body 2 to be energized or de-energized. During implementation, when machining on a gear hobbing machine or machine tool, after finishing one part and before clamping the next, the worker finds that the worktable and fixture are covered with iron filings, or that the generated strip-shaped iron shavings may be entangled on the workpiece or tool. By energizing the electromagnet body 2 through the control component 3, the electromagnet body 2 becomes magnetic and aims at the place where the iron filings are accumulated to attract them. Then, after moving the electromagnet body 2 to the waste bin or designated area, the control component 3 de-energizes the electromagnet body 2. These originally attracted debris will fall into the waste bin or designated area after losing their magnetism, thus achieving precise, quiet, and pollution-free processing.

[0018] Please continue to refer to the reference. Figure 2 The control component 3 includes a circuit board 31 and a power supply 32. The wires on the electromagnet body 2 for transmitting current pass through the interior of the adsorption support 1 and are electrically connected to the circuit board 31. The control component 3 also includes a control housing 33. One end of the adsorption support 1 is detachably connected to the interior of the control housing 33. The interior of the control housing 33 is provided with a housing slot 330 for holding the circuit board 31 in place. The power supply 32 is also located inside the control housing 33. The control housing 33 has a cylindrical shape, making it easy for users to hold with one hand. Since the adsorption support 1 is a long and thin column, and its length is greater than that of the electromagnet body 2 and the control housing 33, the adsorption support 1 can be made of metal materials such as aluminum alloy or easily deformable plastic materials. Therefore, when the user holds the control housing 33, they can use the slender characteristics of the adsorption support 1 to adsorb small iron filings in narrow places that are originally difficult to clean. Unlike traditional large magnetic adsorption devices, the structure in this embodiment is more flexible and easier to carry.

[0019] To facilitate the control of the electromagnet body 2's power supply and de-energization, the circuit board 31 is also electrically connected to an indicator light 34, a charging interface 35, and a button 36. The power supply 32 is also electrically connected to the circuit board 31 via wires. The surface of the control housing 33 is provided with a first clearance hole 331, a second clearance hole 332, and a third clearance hole 333. The indicator light 34, the charging interface 35, and the button 36 pass through the first clearance hole 331, the second clearance hole 332, and the third clearance hole 333 respectively to the outside. With this setup, the electromagnet body 2 is switched between engaged and disengaged states by pressing button 36. Pressing the button energizes the electromagnet, causing it to attract iron filings; pressing the button again demagnetizes the electromagnet. Button 36 can be a high-quality self-resetting tactile switch or membrane switch. Indicator light 34 can be a three-color LED, displaying the status visually through different colors: blue indicates the device is powered on and in standby mode; red indicates the electromagnet is engaged and working; flashing green indicates the battery is charging; and solid green indicates the power supply 32 is fully charged.

[0020] Please refer to the reference. Figure 3 In this embodiment, the power supply 32 includes cylindrical batteries 321 and a support base 322. A lithium battery protection board is connected in series between a plurality of cylindrical batteries 321 and installed inside the support base 322. The lithium battery protection board is electrically connected to the charging interface 35. It is important to note that when charging the cylindrical battery 321, the current setting path or installation path must be: charger to charging interface 35 to lithium battery protection board to cylindrical battery 321; the lithium battery protection board is responsible for ensuring the safety of several cylindrical batteries 321. The lithium battery protection board and cylindrical batteries 321 are encapsulated inside the support base 322. This encapsulation structure and design can be referenced or selected from: BM3451 equalization board.

[0021] In this embodiment, the selection of each component includes, but is not limited to: circuit board 31 is STM8S003, indicator light 34 is 503UR2-EA, button 36 is B3W-1050, and charging interface 35 is Type-C female connector (horizontal surface mount).

[0022] Please continue to refer to the reference. Figure 2 and Figure 3 The control housing 33 has a mounting hole 334 on the side surface away from the adsorption support 1, and the side wall of the adsorption support 1 has a U-shaped hook 37. The side wall of the support base 322 is threaded to or glued to the mounting hole 334 until the columnar battery 321 on the support base 322 extends into the interior of the control housing 33. If the side wall of the support base 322 is threaded into the mounting hole 334, the entire power supply 32 can be easily removed from the inside of the control housing 33, which will bring convenience for subsequent maintenance; the U-shaped hook 37 can be used to attach the entire device to a pocket of clothing or pants, making it easy for users to carry.

[0023] Please refer to the reference. Figure 2 The control housing 33 has a first internal thread 335 on the side near the adsorption support 1, and one end of the adsorption support 1 is provided with a first external thread 11 adapted to and connected to the first internal thread 335. Since the adsorption support 1 is the main support during the magnetic attraction process of the electromagnet body 2 and the main load-bearing component after adsorption, the adsorption support 1 is easily damaged. Therefore, the first external thread 11 and the first internal thread 335 at the end of the adsorption support 1 can be detachably connected to realize the detachable connection between the adsorption support 1 and the control housing 33, which brings convenience for subsequent replacement of the adsorption support 1.

[0024] Please refer to the reference. Figure 3 and Figure 4 An electromagnet support shell 4 is provided on one side of the electromagnet body 2. The electromagnet support shell 4 extends to one side of the adsorption support member 1 and is provided with a second columnar boss 41. The second columnar boss 41 has a second internal thread 411 inside. The other end of the adsorption support member 1 is provided with a second external thread 12 adapted to and connected to the second internal thread 411. The electromagnet support shell 4 is also provided with a threaded hole 42 and a wire avoidance hole 43. During implementation, the wire avoidance hole 43 is mainly used to allow the wires on the electromagnet body 2 to pass through the middle of the electromagnet support shell 4 and the interior of the adsorption support 1 until they are connected to the circuit board 31. The threaded hole 42 realizes the detachable connection between the electromagnet body 2 and the electromagnet support shell 4. This setting is also for the convenience of early installation and later disassembly and maintenance. Since one end of the aforementioned adsorption support 1 has already been detachably connected to the control shell 33, the other end of the adsorption support 1 is detachably connected to the electromagnet support shell 4 through the second external thread 12 and the second internal thread 411. This setting is also for the convenience of early installation and later disassembly and maintenance.

[0025] It should be noted that the cross-sectional shape of the electromagnet body 2, the electromagnet support shell 4, the adsorption support 1 and the control shell 33 are all circular, and the length of the adsorption support 1 is greater than the length of the electromagnet body 2, the control shell 33 or the electromagnet support shell 4. With this design, the entire device is cylindrical in shape, which can avoid friction or scratches between it and the user's hands or clothing. At the same time, the entire device can magnetically attract iron filings in a small design volume.

[0026] Working principle and usage of this utility model: When the user presses button 36, an electrical signal is sent to circuit board 31. Upon receiving the signal, circuit board 31 connects the power supply 32 to the electromagnet body 2. Current flows through the wires, through the cavity inside the adsorption support 1, and finally reaches the electromagnet body 2.

[0027] When the electromagnet body 2 is energized, it instantly generates a strong magnetic field. Using the slender adsorption support 1, the electromagnet support shell 4 is inserted into narrow positions such as the machine tool worktable, the gap of the fixture, and the inner hole of the workpiece. It gently touches or brushes over the iron filings, and the iron filings are adsorbed and collected, thus firmly adsorbing them onto the outer surface of the shell.

[0028] After the iron filings are transported to a waste bin, the user presses button 36 again. Circuit board 31 receives the signal again and cuts off the current to electromagnet body 2 via power supply 32. Electromagnet body 2 immediately loses its magnetism, and the magnetic field disappears. At this time, all iron filings, shavings, etc., adsorbed on electromagnet support shell 4 will automatically and cleanly fall off under their own gravity due to the loss of magnetic attraction, thus completing the release.

[0029] After use, the device can be hung on a tool wall, workbench edge, or pocket via the U-shaped hook 37 on the control housing 33 for easy access and storage.

[0030] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
