In addition, the various specific processes and examples of materials provided by the present application, but those of ordinary skill in the art can appreciate the applicability of other processes and / or the use of other materials.

[0030] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure.

Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0031] See also Figures 1 to 5The embodiment of the present application provides a magnetic workbench, which includes: a support base 100, having a support surface; a magnetic suction table 200, which is arranged on the support surface, and the magnetic suction table 200 includes a first magnetic part 210 spaced apart from the support surface; a second magnetic component 300, which is movably arranged on the support surface and located below the first magnetic part 210; and a magnetic switch component 400, which is movably arranged on the magnetic suction table 200 and is transmission-connected to the second magnetic component 300; the magnetic switch component 400 can drive the second magnetic component 300 to move back and forth, so that when it corresponds to the first magnetic part 210, the magnetic suction table 200 generates a magnetic attraction; or, when it is misaligned with the first magnetic part 210, the magnetic suction table 200 disconnects the magnetic attraction.

[0032] In this embodiment, the magnetic switch component 400 is arranged in the magnetic suction table 200, so that the magnetic switch component 400 and the magnetic suction table 200 share a thickness space, and at least on the side of the support seat 100, the thickness assembly space originally required to be reserved for assembling the magnetic switch component 400 is reduced, thereby reducing the overall thickness of the magnetic workbench, so that it can be applied to machine tools with a small Z stroke in the thickness direction, and has strong versatility. At the same time, the magnetic switch component 400 is transmission-connected to the second magnetic component 300 movably arranged on the support seat 100, so that the relative position of the second magnetic component 300 and the first magnetic part 210 can be adjusted by adjusting the operating state of the magnetic switch component 400, so that the magnetic suction table 200 has a magnetic attraction and can magnetically fix the workpiece to be processed; or, the magnetic suction table 200 has no magnetic attraction, so as to facilitate the removal of the aforementioned workpiece and ensure the personal safety of the overall operation.

[0033] Specifically, the magnetic workbench is configured as a composite component including at least a support base 100, a magnetic suction table 200, a second magnetic component 300 and a magnetic switch 400. The support base 100 may be a plate-like structure with a certain rigidity and hardness, and is used to integrate and support components such as the second magnetic component 300, the magnetic suction table 200 and the magnetic switch 400. The second magnetic component 300 may be a composite plate-like structure with a small magnet, which is movably arranged on the support surface and can reciprocate along the length direction Y or the width direction X of the magnetic workbench to cooperate with the first magnetic part 210 in this direction to realize the conduction and disconnection of the magnetic suction force of the magnetic suction table 200. The magnetic table 200 can be made of soft magnetic material, which can be detachably set on the support surface of the support seat 100 and cover the second magnetic component 300; the relative position of the magnetic table 200 and the support seat 100 is fixed, and the space formed between the two for the operation of the second magnetic component 300 is stable and has strong anti-interference, which is conducive to the magnetic conduction and demagnetization operation of the second magnetic component 300, and improves the magnetic fixation effect and use safety of the magnetic workbench. The magnetic switch component 400 can be a locking magnetic switch with a gear or a connecting rod, which can be movably inserted in the magnetic table 200 and at least partially exposed from the magnetic table 200; the part of the magnetic switch component 400 that extends into the magnetic table 200 is transmission-connected to the second magnetic component 300, for example, the transmission can be achieved through meshing or a connecting rod. The magnetic switch component 400 can be arranged in the length direction Y of the magnetic workbench. In this case, the overall width and thickness of the formed magnetic workbench are relatively small, which can be applied to usage scenarios with strict width assembly space and / or thickness assembly space; or, the magnetic switch component 400 can also be arranged in the width direction X of the magnetic workbench. In this case, the overall length and thickness of the formed magnetic workbench are relatively small, which can be applied to usage scenarios with strict length assembly space and / or thickness assembly space.

[0034] Based on the above, the implementation mechanism of the magnetic workbench provided in this embodiment is as follows: Figure 4, rotate the magnetic switch 400 counterclockwise to turn on the magnetic switch 400 and put it in the ON state. At this time, the second magnetic component 300 is driven to move in a direction away from the magnetic switch 400, and the small magnet thereon moves outward until it moves to the bottom of the first magnetic part 210 in the magnetic suction table 200. The first magnetic part 210 and the small magnet generate magnetism relative to each other, and the side of the magnetic suction table 200 away from the support seat 100 generates magnetic attraction, which can absorb the workpiece to be processed; after the workpiece to be processed is processed, rotate the magnetic switch 400 clockwise to turn off the magnetic switch 400 and put it in the OFF state. At this time, the second magnetic component 300 is driven to move in a direction close to the magnetic switch 400, and the small magnet thereon moves inward until it moves to a position misaligned with the first magnetic part 210 in the magnetic suction table 200. The first magnetic part 210 does not generate magnetism, and the side of the magnetic suction table 200 away from the support seat 100 does not generate magnetic attraction, so the workpiece to be processed can be easily picked up. It should be explained that this example is explained by taking the second magnetic component 300 moving along the length direction Y of the magnetic workbench and the magnetic switch 400 being arranged in the length direction Y of the magnetic workbench as an example. When the second magnetic component 300 moves in other directions and the magnetic switch 400 is arranged in other directions, only the orientation changes, and the other theories for realizing magnetic attraction control are as above and will not be elaborated on.

[0035] In one example, a groove 101 may be provided on the top of the support base 100, such as Figure 3 and Figure 5 , so as to realize the storage of the second magnetic component 300 in the thickness direction Z. At this time, the second magnetic component 300 accommodated in the groove 101 reciprocates on the bottom wall of the groove 101, and its periphery is limited by the peripheral groove wall of the groove 101. Alternatively, in other embodiments, the second magnetic component 300 can be stored in the thickness direction Z by providing the groove 101 at the bottom of the magnetic suction table 200. At this time, the magnetic suction table 200 is covered outside the second magnetic component 300 through the groove 101, and the second magnetic component 300 slides on the smooth and flat support surface, and its periphery is limited by the peripheral groove wall of the groove 101 and is spaced from the bottom wall of the groove 101. Specifically, the groove 101 can be a nearly rectangular groove structure with a certain groove depth, which can ensure that the top surface of the second magnetic component 300 movably assembled therein is contained in the support surface, preventing the top surface of the second magnetic component 300 from rubbing against the bottom surface of the magnetic suction table 200 during movement, thereby reducing damage to components; and ensuring the smooth movement of the second magnetic component 300, reducing the interference of the bottom surface of the magnetic suction table 200 on the movement of the second magnetic component 300, and improving the magnetic conduction / demagnetization sensitivity of the magnetic workbench.

[0036] like Figure 3 and Figure 4As shown, in a possible implementation, the second magnetic component 300 includes a fixing member 310, a second magnet 320 and a rack 330, the second magnet 320 and the rack 330 are sequentially arranged on the fixing member 310, the fixing member 310 is movably arranged on the supporting surface, and the magnetic switch member 400 is meshedly connected with the rack 330.

[0037] In this embodiment, the specific configuration of the second magnetic component 300 is optimized. Specifically, the second magnetic component 300 is configured as a composite component including at least a fixing member 310, a second magnet 320 and a rack 330. The fixing member 310 can be a flat plate structure with a plurality of vias arranged thereon, and the plurality of vias are distributed in an array. The second magnet 320 can include a plurality of small magnets, one of which is embedded in a via. In this way, the magnetic attraction of the second magnetic component 300 can be increased at least in quantity, ensuring the magnetic attraction fixing effect on the magnetic suction table 200 side. The rack 330 may be in the shape of a long strip, and may be connected to the fixing member 310 by welding or hot melting, or may be connected to the fixing member 310 by clamping or fasteners such as screws / bolts; the rack 330 is meshed and connected with the magnetic switch member 400, so that the rack 330 may be driven to move in a straight line by rotating the magnetic switch member 400, thereby realizing the linear movement of the fixing member 310 and the second magnet 320, realizing the relative position adjustment of the second magnet 320 and the first magnetic part 210, thereby realizing the magnetization and demagnetization of the magnetic workbench; the rack 330 may extend along the length direction Y of the magnetic workbench to drive the second magnetic component 300 to move back and forth in this direction, thereby realizing the magnetization and demagnetization performance of the magnetic suction table 200 in the length direction Y; or, the rack 330 may also extend along the width direction X of the magnetic workbench to drive the second magnetic component 300 to move back and forth in this direction, thereby realizing the magnetization and demagnetization performance of the magnetic suction table 200 in the width direction X. The transmission process between the second magnetic component 300 and the magnetic switch component 400 provided in this example is stable and controllable, the transmission position is accurate and reliable, the magnetic on / off state is accurately controlled, and the magnetic adsorption and fixing operation is highly safe.

[0038] like Figure 3 and Figure 4 As shown, in a possible implementation, the rack 330 extends out of the fixing member 310 on a side away from the support base 100, and the magnetic switch member 400 includes an axially connected switch key 410 and a gear shaft 420, the switch key 410 is located on the outside of the magnetic suction platform 200, and the gear shaft 420 extends into the magnetic suction platform 200 and is meshedly connected above the rack 330.

[0039] In this embodiment, the specific configuration of the magnetic switch 400 is optimized. Specifically, an escape notch is provided at the bottom of the magnetic suction table 200 corresponding to the position of the rack 330; and the rack 330 is arranged to protrude from the fixing member 310 so that at least part of the rack 330 can be accommodated in the aforementioned escape notch, so that the second magnetic component 300 and the magnetic switch 400 can be connected in the magnetic suction table 200, so that the two can share the thickness space of the magnetic suction table 200. At the same time, the magnetic switch component 400 is configured as a combined component including at least a switch key 410 and a gear shaft 420. The switch key 410 can be a mechanical knob, which can be connected to the outer end of the gear shaft 420 and form an integral structure with the gear shaft 420. In this way, the rotation of the gear shaft 420 can be achieved by directly rotating the switch key 410, thereby achieving the following of the rack 330, the fixing member 310 and the second magnet 320; the switch key 410 can also be a hexagonal wrench, which forms a split layout with the gear shaft 420. When the gear shaft 420 needs to be rotated, it is inserted into the end hole of the outer end of the gear shaft 420 to achieve the rotation of the gear shaft 420. The gear shaft 420 may be a long shaft structure with a plurality of long teeth on the outer wall, and the plurality of long teeth are spaced and distributed on the outer circumference of the gear shaft 420; the long teeth extend along the axial direction of the gear shaft 420 and may mesh with the rack 330, so that the rack 330 may be driven to move linearly by rotating the gear shaft 420, thereby driving the fixing member 310 and the second magnet 320 to move synchronously, so as to adjust the relative position of the second magnet 320 and the first magnetic part 210, and realize the magnetic conduction and demagnetization of the magnetic suction table 200. In this example, the rack 330 is arranged above the fixing member 310, and at the same time, the magnetic switch member 400 is arranged above the rack 330, so that the meshing position of the second magnetic component 300 and the magnetic switch member 400 is arranged in the magnetic suction table 200, thereby further reducing the space occupied by the magnetic workbench in the thickness direction Z thereof, reducing the overall thickness, and realizing a thin and light layout of the magnetic workbench.

[0040] like Figure 1 and Figure 4 As shown, in a possible implementation manner, a plug-in hole 201 is provided on the magnetic suction table 200, a plug-in ring groove 401 is provided between the gear shaft 420 and the switch key 410, the plug-in ring groove 401 is connected to the plug-in hole 201, and the magnetic switch component 400 also includes a positioning pin 430, which passes through the plug-in hole 201 and is plugged into the plug-in ring groove 401.

[0041] In this embodiment, the specific configuration of the magnetic switch component 400 is further optimized. Specifically, a plug hole 201 is provided on the magnetic suction table 200, and the plug hole 201 can extend along the length direction Y of the magnetic workbench and connect the movable hole of the magnetic switch component 400. At the same time, the magnetic switch component 400 is configured as a composite component including at least a switch key 410, a gear shaft 420 and a positioning pin 430. The positioning pin 430 can be a long shaft pin, which can extend along the length direction Y of the magnetic workbench to pass through the plug hole 201 in this direction and be plugged into the magnetic suction table 200, and the inner end thereof is plugged into the plug ring groove 401, thereby realizing the position locking of the magnetic switch component 400. The magnetic switch member 400 provided in this example can lock the gear shaft 420 in the ON state or the OFF state, preventing the gear shaft 420 from continuing to rotate or rotating in the opposite direction, so that the relative position of the second magnetic component 300 and the magnetic suction table 200 is fixed, and the control accuracy of the magnetic suction force of the magnetic workbench is high, and the reliability is stronger, which is suitable for use scenarios with high requirements for the width direction X stroke.

[0042] Of course, in other embodiments, the plug hole 201 can also extend along the width direction X of the magnetic workbench. In this case, the positioning pin 430 extends along the width direction X of the magnetic workbench, and the relative position of the magnetic switch 400 and the magnetic suction table 200 can be locked in this direction. The magnetic switch 400 provided in this example is suitable for use scenarios with high requirements for the length direction Y travel of the magnetic workbench.

[0043] like Figure 3 As shown, in a possible implementation, a limiting hole 301 is provided on the second magnetic component 300, and the magnetic workbench also includes a limiting support member 500, which is provided on the supporting surface and inserted into the limiting hole 301, and the side of the limiting support member 500 away from the supporting seat 100 is in contact with the magnetic suction table 200.

[0044] In this embodiment, the specific configuration of the magnetic workbench is further optimized. Specifically, the magnetic workbench is configured as a composite component including at least a support base 100, a magnetic suction table 200, a second magnetic component 300, a magnetic switch 400 and a position-limiting support 500. The position-limiting support 500 can be a columnar structure or a block structure, and its bottom end surface can be connected to the groove 101 by welding or the like, and the top end surface is flush with the support surface of the support base 100, or slightly protrudes from the support surface within the error range to support the bottom surface of the magnetic suction table 200, so as to avoid the magnetic suction table 200 shaking during the movement of the second magnetic component 300 and causing the magnetic suction surface thereon to tilt, thereby improving the flatness of the magnetic suction table 200 and the magnetic suction accuracy, thereby realizing the processing of ultra-high precision parts. The limiting hole 301 can be a long waist hole, and the second magnetic component 300 is sleeved on the outside of the limiting support 500 through the limiting hole 301; the limiting hole 301 has an offset length along the length direction Y of the magnetic workbench, and can provide the second magnetic component 300 with a maximum reciprocating stroke in this direction, preventing the second magnetic component 300 from moving too far away from the magnetic switch component 400, thereby releasing the transmission connection between the magnetic switch component 400 and the second magnetic component 300, or preventing the second magnetic component 300 from moving too close to the magnetic switch component 400, thereby causing extrusion and damage between the two, thereby improving the transmission reliability and stability of the second magnetic component 300 and the magnetic switch component 400, and extending the service life. In addition, the second magnetic component 300 is connected to the limiting support 500 through the limiting hole 301, which can also improve the adjustment accuracy of the alignment magnetic flux and misalignment magnetic interruption between the second magnet 320 and the first magnetic part 210, improve the magnetic attraction strength and magnetic adsorption effect in the ON state, and improve operation safety.

[0045] like Figure 1 As shown, in a possible implementation manner, the magnetic suction table 200 further includes a connecting portion 220 and a mounting portion 230 which are sequentially arranged, the first magnetic portion 210 is arranged between the connecting portion 220 and the mounting portion 230 , and the magnetic switch component 400 is movably arranged on the mounting portion 230 .

[0046] In this embodiment, the specific configuration of the magnetic suction table 200 is further optimized. Specifically, the magnetic suction table 200 is configured as a composite component including at least a first magnetic part 210, a connecting part 220 and a mounting part 230. The connecting part 220 can be a rectangular block structure, and the mounting part 230 can be a rectangular block structure; in the distribution direction of the two, the length of the mounting part 230 is slightly greater than the length of the connecting part 220, so as to provide sufficient assembly space for the magnetic switch 400. The connecting part 220 and the mounting part 230 are respectively arranged at the opposite ends of the first magnetic part 210, so as to realize magnetic isolation protection at both ends of the first magnetic part 210 in this direction, thereby improving the safety of the magnetic adsorption operation of the magnetic suction table 200.

[0047] In one example, the connecting portion 220, the first magnetic portion 210 and the mounting portion 230 can be arranged in sequence along the length direction Y of the magnetic workbench to adapt to the use scenario with a higher requirement for the travel in the width direction X. Alternatively, the three can also be arranged in sequence along the width direction X of the magnetic workbench to adapt to the use scenario with a higher requirement for the travel in the length direction Y.

[0048] like Figure 1 , Figure 2 and Figure 5 As shown, in a possible implementation manner, the magnetic attraction platform 200 further includes a magnetic isolation member 240 wrapped around the outside of the first magnetic portion 210 , and two ends of the magnetic isolation member 240 are respectively connected to the connecting portion 220 and the mounting portion 230 .

[0049] In this embodiment, the specific configuration of the magnetic suction table 200 is further optimized. Specifically, the magnetic suction table 200 is configured as a composite component including at least a first magnetic part 210, a connecting part 220, a mounting part 230 and a magnetic shielding part 240. The magnetic shielding part 240 can be a long strip, which can be fastened to the outer wall of the first magnetic part 210 by fasteners such as screws / bolts, or can be connected by bonding or the like; its two ends are respectively abutted against the connecting part 220 and the mounting part 230 to achieve magnetic insulation protection for the two side walls of the first magnetic part 210, so that only the magnetic surface of the magnetic suction table 200 remains magnetic, further improving the safety of the magnetic adsorption operation of the magnetic suction table 200. In addition, the provision of the magnetic shielding part 240 can enable multiple magnetic workbenches to operate in the same space, isolating the magnetic interference between the multiple magnetic workbenches, and improving the safety of the operation.

[0050] like Figure 1 , Figure 2 and Figure 5 As shown, in a possible implementation, the first magnetic part 210 includes a plurality of iron parts 211, a plurality of copper magnetic parts 212 and a connecting part 213. In the direction from the connecting part 220 to the mounting part 230, an iron part 211 and a copper magnetic part 212 are alternately arranged, and the connecting part 213 passes through the connecting part 220 and the first magnetic part 210 in sequence and is inserted into the mounting part 230.

[0051] In this embodiment, the specific configuration of the first magnetic part 210 is optimized. Specifically, the first magnetic part 210 is configured as a composite component including at least a plurality of iron pieces 211, a plurality of copper magnetic pieces 212 and a connecting piece 213. The iron piece 211 can be a long plate structure, and the copper magnetic piece 212 can be a long plate structure with a thickness and length equivalent to that of the iron piece 211. In this way, the iron pieces 211 and the copper magnetic pieces 212 can be arranged alternately in the direction from the connecting part 220 to the mounting part 230 to form a nearly quadrilateral structure; the connecting piece 213 can be a long-axis screw, which passes through the connecting part 220 and sequentially passes through the quadrilateral structure in which the iron pieces 211 and the copper magnetic pieces 212 are alternately distributed, and finally inserted into the mounting part 230 to achieve the connection and fastening of the magnetic suction table 200 in this direction, thereby improving the structural stability and reliability of the magnetic suction table 200.

The seat body 110 can be a thin plate-like structure, which can support the magnetic suction table 200 and the second magnetic component 300 to provide a stable magnetic suction fixing environment for the workpiece to be processed; and can cooperate with the magnetic suction table 200 to provide a relatively independent working environment for the second magnetic component 300 and the magnetic switch 400, reduce external environmental interference, and improve the control accuracy of magnetic on and off and the safety of magnetic suction fixing. The first locking member can be a fastener such as a long screw or a long bolt, with a limiting head. When it is screwed on the processing device, it can ensure that the middle and rear sections of the first locking member pass through the connection notch 111 on the seat body 110 and are plugged into the processing device. At the same time, the head is clamped above the connection notch 111, which improves the connection tightness and reliability between the support seat 100 and the processing device. The support base 100 provided in this example has a simple structure, is easy to process, and has low cost; moreover, the connection notch 111 provided thereon can effectively reduce the overall weight, which is conducive to the lightweight layout of the magnetic workbench.

Specifically, the magnetic workbench is configured as a composite component including at least a support base 100, a magnetic suction table 200, a second magnetic component 300, a magnetic switch 400 and a second locking member 600. The second locking member 600 can be a fastener such as a long screw or a long bolt. The second locking member 600 can pass through the magnetic suction table 200 and be inserted into the support base 100 in sequence, thereby realizing the connection and fastening of the magnetic suction table 200 and the support base 100, with strong connection reliability and stable overall structure.

[0057] It can be understood that the magnetic table 200 is provided with a connecting through hole that passes through along its thickness direction Z, and an internal thread structure can be provided in the connecting through hole; at this time, the support seat 100 is provided with a fixed hidden hole that is concave along its thickness direction Z, and the inside of the fixed hidden hole corresponds to the connecting through hole, and an internal thread structure can be provided. In this way, the corresponding external thread structure can be provided on the outer wall of the second locking member 600 to further strengthen the connection tightness between the second locking member 600 and the magnetic table 200, the second locking member 600 and the support seat 100, and the magnetic table 200 and the support seat 100, thereby further improving the overall structural stability and reliability of the magnetic workbench.
