Description

Technical Field

[0001] This application relates to the field of processing equipment technology, and in particular to a magnetic worktable and processing equipment. Prior Technology

[0002] A magnetic worktable is a device that uses magnetic force to attract workpieces and is widely used in the machining industry. In related technologies, a traditional magnetic worktable generally includes a base, a magnetic platform mounted above the base, and a magnetic switch positioned between the two. The magnetic switch is movably mounted in the base and is connected to the magnetic platform via a transmission mechanism. Operators can adjust the relative position of the magnetic platform and the base by turning the magnetic switch on and off, thereby changing the magnitude of the magnetic force and achieving magnetic / non-magnetic adjustment of the worktable. Because the magnetic switch has a certain thickness, sufficient space needs to be reserved on the base for assembly. This results in a large footprint for the entire magnetic worktable in the thickness direction, making it unsuitable for machine tools with small travel distances in the thickness direction, thus limiting its applicability. Summary of the Invention

[0003] This application provides a magnetic worktable and processing equipment to solve the technical problem that traditional magnetic worktables occupy a large space in the thickness direction, cannot be adapted to machine tools with small stroke in this direction, and have a limited range of applications.

[0004] To this end, in a first aspect, embodiments of this application provide a magnetic worktable, comprising: a support base having a support surface; a magnetic suction table disposed on the support surface, the magnetic suction table including a first magnetic part spaced apart from the support surface; a second magnetic component movably disposed on the support surface and located below the first magnetic part; and a magnetic switch movably disposed on the magnetic suction table and connected to the second magnetic component in a transmission manner; the magnetic switch can drive the second magnetic component to reciprocate so that when it corresponds to the first magnetic part, the magnetic suction table generates a magnetic attraction force; or, when it is misaligned with the first magnetic part, the magnetic suction table disconnects the magnetic attraction force.

[0005] In one possible implementation, the second magnetic component includes a fixing member, a second magnet, and a rack. The second magnet and the rack are sequentially disposed on the fixing member, the fixing member is movably disposed on the support surface, and the magnetic switch is engaged with the rack.

[0006] In one possible implementation, the rack extends from the side away from the support base, and the magnetic switch includes an axially connected switch and a gear shaft. The switch is located outside the magnetic suction table, and the gear shaft extends into the magnetic suction table and is engaged with the rack above it.

[0007] In one possible implementation, the magnetic suction table is provided with a plug hole, and a plug ring groove is provided between the gear shaft and the switch. The plug ring groove communicates with the plug hole. The magnetic switch also includes a positioning pin, which passes through the plug hole and is inserted into the plug ring groove.

[0008] In one possible implementation, the second magnetic component is provided with a limiting hole, and the magnetic worktable further includes a limiting support member. The limiting support member is disposed in the groove and inserted into the limiting hole, and the side of the limiting support member away from the support base abuts against the magnetic suction table.

[0009] In one possible implementation, the magnetic suction table further includes a connecting part and a mounting part arranged in sequence, a first magnetic part is disposed between the connecting part and the mounting part, and a magnetic switch is movably disposed on the mounting part.

[0010] In one possible implementation, the magnetic suction table further includes a magnetic shielding member wrapped around the outside of the first magnetic part, with its two ends connected to the connecting part and the mounting part, respectively.

[0011] In one possible implementation, the first magnetic part includes multiple iron parts, multiple copper magnetic parts, and connectors. In the direction from the connector to the mounting part, one iron part and one copper magnetic part are alternately arranged.

[0014] According to the embodiments of this application, the magnetic worktable and processing equipment include: a support base having a support surface; a magnetic suction table disposed on the support surface, the magnetic suction table including a first magnetic part spaced apart from the support surface; a second magnetic component movably disposed on the support surface and located below the first magnetic part; and a magnetic switch component movably disposed on the magnetic suction table and connected to the second magnetic component via transmission. The magnetic switch component can drive the second magnetic component to reciprocate, so that when it corresponds to the first magnetic part, the magnetic suction table generates a magnetic attraction force; or, when it is misaligned with the first magnetic part, the magnetic suction table disconnects the magnetic attraction force. The technical means of this application involve placing the magnetic switch component in the magnetic suction table so that the magnetic switch component and the magnetic suction table share a thickness space, reducing the thickness assembly space required for assembling the magnetic switch component, at least on the support base side, thereby reducing the overall thickness of the magnetic worktable and making it suitable for machine tools with small travel in the thickness direction, thus exhibiting strong versatility. At the same time, the magnetic switch is connected to the second magnetic component, which is movably disposed between the support base and the first magnetic part.

[0016] To make the objectives, technical means, and advantages of the embodiments of this application clearer, the technical means of the embodiments of this application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

[0019] Referring to Figures 1 to 5, this application embodiment provides a magnetic worktable, which includes: a support base 100 having a support surface; a magnetic suction table 200 disposed on the support surface, the magnetic suction table 200 including a first magnetic part 210 spaced apart from the support surface; a second magnetic component 300 movably disposed on the support surface and located below the first magnetic part 210; and a magnetic switch 400 movably disposed on the magnetic suction table 200 and connected to the second magnetic component 300 in a transmission manner; the magnetic switch 400 can drive the second magnetic component 300 to reciprocate, so that when it corresponds to the first magnetic part 210, the magnetic suction table 200 generates a magnetic attraction force; or, when it is misaligned with the first magnetic part 210, the magnetic suction table 200 disconnects the magnetic attraction force.

[0020] In this embodiment, the magnetic switch 400 is disposed in the magnetic suction table 200 so that the magnetic switch 400 and the magnetic suction table 200 share a common thickness space. This reduces the thickness assembly space that would otherwise need to be reserved for assembling the magnetic switch 400, at least on the support base 100 side, thereby reducing the overall thickness of the magnetic worktable and making it suitable for machine tools with small Z-stroke in the thickness direction, thus enhancing its versatility. Simultaneously, the magnetic switch 400 is connected to the second magnetic component 300, which is movably mounted on the support base 100. This allows the relative position of the second magnetic component 300 and the first magnetic part 210 to be adjusted by regulating the operating state of the magnetic switch 400. This enables the magnetic suction table 200 to have magnetic attraction, allowing it to magnetically hold the workpiece to be processed; or, alternatively, it can be made to lack magnetic attraction, facilitating the removal of the workpiece and ensuring overall operational safety.

[0021] Specifically, the magnetic worktable is configured as a combination component including at least a support base 100, a magnetic suction table 200, a second magnetic component 300, and a magnetic switch component 400. The support base 100 can be a plate-like structure with a certain rigidity and hardness, used to integrate and support components such as the second magnetic component 300, the magnetic suction table 200, and the magnetic switch component 400. The second magnetic component 300 can be a composite plate-like structure with small magnets, movably mounted on the support surface, and can reciprocate along the length direction Y or width direction X of the magnetic worktable to cooperate with the first magnetic part 210 in that direction to realize the magnetic attraction force of the magnetic suction table 200 being turned on and off. The magnetic platform 200 can be made of soft magnetic material and is detachably mounted on the support surface of the support base 100, covering the second magnetic component 300. The relative position of the magnetic platform 200 and the support base 100 is fixed, and the space formed between them for the second magnetic component 300 to operate is stable and has strong anti-interference ability, which is beneficial to the magnetic connection and demagnetization of the second magnetic component 300, improving the magnetic attraction and fixation effect and safety of the magnetic worktable. The magnetic switch 400 can be a locking magnetic switch with gears or linkages, which can be movably inserted into the magnetic platform 200 and at least partially exposed. The part of the magnetic switch 400 extending into the magnetic platform 200 is connected to the second magnetic component 300 through transmission, such as through meshing or linkages. The magnetic switch 400 can be set in the length direction Y of the magnetic worktable. In this case, the overall width and thickness of the magnetic worktable are small, which is suitable for applications with strict width and / or thickness assembly space requirements. Alternatively, the magnetic switch 400 can also be set in the width direction X of the magnetic worktable. In this case, the overall length and thickness of the magnetic worktable are small, which is suitable for applications with strict length and / or thickness assembly space requirements.

[0022] The implementation mechanism of the magnetic worktable provided in this embodiment is as follows: As shown in Figure 4, rotating the magnetic switch 400 counterclockwise turns it on, placing it in the ON state. At this time, the second magnetic component 300 is driven to move away from the magnetic switch 400, and the small magnet on it moves outward until it reaches directly below 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 base 100 generates magnetic attraction force, which can... The workpiece to be processed is adsorbed. After the workpiece is processed, the magnetic switch 400 is rotated clockwise to turn it off, placing it in the OFF state. At this time, the second magnetic component 300 is driven to move closer to the magnetic switch 400, and the small magnet on it moves inward until it is misaligned with the first magnetic part 210 in the magnetic suction table 200. The first magnetic part 210 no longer generates magnetism, and the side of the magnetic suction table 200 away from the support base 100 does not generate magnetic attraction, making it easy to pick up the workpiece. It should be explained that this example uses the second magnetic component 300 moving along the length Y direction of the magnetic worktable, with the magnetic switch 400 positioned along the length Y direction of the magnetic worktable. When the second magnetic component 300 moves in other directions, and the magnetic switch 400 is positioned in other directions, only the orientation changes; the other theories for achieving magnetic attraction control are as described above and will not be elaborated further.

[0023] In one example, the second magnetic component 300 can be housed in its thickness direction Z by providing a groove 101 on the top of the support 100, as shown in Figures 3 and 5. In this case, the second magnetic component 300 housed in the groove 101 reciprocates on the bottom wall of the groove 101, and its periphery is constrained by the peripheral wall of the groove 101. Alternatively, in other embodiments, the second magnetic component 300 can also be housed in its thickness direction Z by providing a groove 101 on the bottom of the magnetic stage 200. In this case, the magnetic stage 200 covers the second magnetic component 300 through the groove 101, and the second magnetic component 300 slides on a smooth and flat support surface, and its periphery is constrained by the peripheral wall of the groove 101 and spaced apart from the bottom wall of the groove 101. Specifically, the groove 101 can be a near-rectangular recessed structure with a certain depth. This depth ensures that the top surface of the second magnetic component 300, which is movably assembled therein, is contained within the support surface, preventing the top surface of the second magnetic component 300 from rubbing against the bottom surface of the magnetic stage 200 during movement and reducing component damage. Furthermore, it ensures the smooth movement of the second magnetic component 300, reduces interference from the bottom surface of the magnetic stage 200 on the movement of the second magnetic component 300, and improves the sensitivity of the magnetic stage for magnetization / demagnetization.

[0024] As shown in Figures 3 and 4, in one possible embodiment, 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 disposed on the fixing member 310, the fixing member 310 is movably disposed on the support surface, and the magnetic switch 400 is engaged with the rack 330.

[0025] In this embodiment, the specific configuration of the second magnetic component 300 is optimized. Specifically, the second magnetic component 300 is configured as a combination of at least a fixing member 310, a second magnet 320, and a rack and pinion 330. The fixing member 310 can be a flat plate structure with multiple through holes arranged in an array. The second magnet 320 can include multiple small magnets, with each small magnet being embedded in a through hole. In this way, the magnetic attraction force of the second magnetic component 300 can be increased at least in terms of quantity, ensuring the magnetic attraction and fixation effect on the magnetic stage 200 side. The rack 330 can be elongated and can be connected to the fixing member 310 by welding or hot melting, or by snap-fitting or fasteners such as screws / bolts. The rack 330 is engaged with the magnetic switch member 400. Thus, by rotating the magnetic switch member 400, the rack 330 can be driven to move linearly, thereby realizing the linear movement of the fixing member 310 and the second magnet 320, and adjusting the relative position of the second magnet 320 and the first magnetic part 210, thereby realizing the magnetic activation and deactivation of the magnetic worktable. The rack 330 can extend along the length direction Y of the magnetic worktable to drive the second magnetic component 300 to reciprocate in that direction, thereby realizing the magnetic activation and deactivation of the magnetic suction table 200 in the length direction Y. Alternatively, the rack 330 can also extend along the width direction X of the magnetic worktable to drive the second magnetic component 300 to reciprocate in that direction, thereby realizing the magnetic activation and deactivation of the magnetic suction table 200 in the width direction X. The transmission process between the second magnetic component 300 and the magnetic switch 400 provided in this example is stable and controllable, the transmission position is precise and reliable, the magnetic on / off state is precisely controlled, and the magnetic adsorption fixing operation is highly safe.

[0026] As shown in Figures 3 and 4, in one possible embodiment, the rack 330 extends out of the fixing member 310 on the side away from the support base 100, and the magnetic switch member 400 includes an axially connected switch 410 and a gear shaft 420. The switch 410 is located outside the magnetic suction table 200, and the gear shaft 420 extends into the magnetic suction table 200 and is engaged with the rack 330 above it.

[0027] In this embodiment, the specific configuration of the magnetic switch 400 is optimized. Specifically, a clearance notch is provided at the bottom of the magnetic stage 200 corresponding to the position of the rack 330; and the rack 330 is provided to protrude from the fixing member 310 so that at least a portion of the rack 330 can be accommodated in the aforementioned clearance notch, thereby enabling the transmission connection between the second magnetic component 300 and the magnetic switch 400 in the magnetic stage 200, allowing the two to share the thickness space of the magnetic stage 200. Meanwhile, the magnetic switch 400 is configured as a combination component including at least a switch 410 and a gear shaft 420. The switch 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 gear shaft 420 can be rotated by directly rotating the switch 410, thereby realizing the driven action of the rack 330, the fixing member 310 and the second magnet 320. The switch 410 can also be a hexagonal wrench, which forms a separate layout with the gear shaft 420. When it is necessary to rotate the gear shaft 420, it is inserted into the end hole at the outer end of the gear shaft 420 to realize the rotation of the gear shaft 420. The gear shaft 420 can be a long shaft structure with multiple long teeth on its outer wall, with the long teeth spaced apart on the outer circumference of the gear shaft 420. These long teeth extend axially along the gear shaft 420 and mesh with the rack 330. Thus, by rotating the gear shaft 420, the rack 330 can be moved linearly, thereby causing the fixing member 310 and the second magnet 320 to move synchronously. This allows for adjustment of the relative position of the second magnet 320 and the first magnetic part 210, enabling the magnetic stage 200 to be magnetically activated and deactivated. In this example, the rack 330 is positioned above the fixing member 310, and the magnetic switch 400 is also positioned above the rack 330. This positions the second magnetic component 300 and the magnetic switch 400 within the magnetic stage 200, further reducing the space occupied by the magnetic stage in its thickness direction Z, decreasing the overall thickness, and achieving a thinner and lighter magnetic stage layout.

[0028] As shown in Figures 1 and 4, in one possible embodiment, the magnetic suction table 200 is provided with a plug hole 201, and a plug ring groove 401 is provided between the gear shaft 420 and the switch 410. The plug ring groove 401 communicates with the plug hole 201. The magnetic switch component 400 also includes a positioning pin 430, which passes through the plug hole 201 and is inserted into the plug ring groove 401.

[0029] In this embodiment, the specific configuration of the magnetic switch 400 is further optimized. Specifically, a insertion hole 201 is provided on the magnetic stage 200. This insertion hole 201 can extend along the length direction Y of the magnetic stage and connect to the movable hole of the magnetic switch 400. At the same time, the magnetic switch 400 is configured as a combination component including at least a switch 410, a gear shaft 420, and a positioning pin 430. The positioning pin 430 can be a long shaft pin that can extend along the length direction Y of the magnetic stage to pass through the insertion hole 201 in this direction and be inserted into the magnetic stage 200, with its inner end inserted into the insertion ring groove 401, thereby achieving position locking of the magnetic switch 400. The magnetic switch 400 provided in this example can lock the gear shaft 420 in the ON or OFF state, preventing the gear shaft 420 from continuing to rotate or rotating in the opposite direction, thus fixing the relative position of the second magnetic component 300 and the magnetic stage 200. It provides high precision and reliability in controlling the magnetic attraction force of the magnetic worktable, and is suitable for applications with high requirements for the X-stroke in the width direction.

[0030] Of course, in other embodiments, the insertion hole 201 can also extend along the width direction X of the magnetic worktable. In this case, the positioning pin 430 extends along the width direction X of the magnetic worktable, which can lock the relative position of the magnetic switch 400 and the magnetic table 200 in this direction. The magnetic switch 400 provided in this example is suitable for applications where the length direction Y travel of the magnetic worktable is required to be high.

[0031] As shown in Figure 3, in one possible implementation, the second magnetic component 300 is provided with a limiting hole 301, and the magnetic worktable also includes a limiting support 500. The limiting support 500 is provided on the support surface and inserted into the limiting hole 301. The side of the limiting support 500 away from the support base 100 abuts against the magnetic suction table 200.

[0032] In this embodiment, the specific configuration of the magnetic worktable is further optimized. Specifically, the magnetic worktable is configured as a combination of at least a support base 100, a magnetic suction table 200, a second magnetic component 300, a magnetic switch component 400, and a limiting support component 500. The limiting support component 500 can be a columnar structure or a block structure. Its bottom end can be connected to the groove 101 by welding or other means. Its top end 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. This prevents the magnetic suction table 200 from shaking and tilting its magnetic adsorption surface during the movement of the second magnetic component 300, thereby improving the flatness of the magnetic suction table 200 and the magnetic adsorption accuracy, thus enabling the processing of ultra-high precision parts. The limiting hole 301 can be an elongated hole through which the second magnetic component 300 is sleeved on the outside of the limiting support 500. The limiting hole 301 has a misaligned length along the length direction Y of the magnetic worktable and can provide the second magnetic component 300 with the maximum stroke for reciprocating movement in this direction. This prevents the second magnetic component 300 from moving too far away from the magnetic switch component 400, which would disengage the transmission connection between the magnetic switch component 400 and the second magnetic component 300, or prevents the second magnetic component 300 from moving too close to the magnetic switch component 400, which would cause compression and damage between the two. This improves the transmission reliability and stability between the second magnetic component 300 and the magnetic switch component 400 and extends their service life. In addition, the second magnetic component 300 is connected to the limiting support 500 through the limiting hole 301, which can improve the accuracy of the alignment and magnetization adjustment of 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 the safety of operation.

[0033] As shown in Figure 1, in one possible embodiment, the magnetic suction table 200 further includes a connecting part 220 and a mounting part 230 arranged sequentially, a first magnetic part 210 is disposed between the connecting part 220 and the mounting part 230, and a magnetic switch 400 is movably disposed on the mounting part 230.

[0034] 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 combined 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 their distribution direction, the length of the mounting part 230 is slightly greater than the length of the connecting part 220 to provide sufficient assembly space for the magnetic switch component 400. The connecting part 220 and the mounting part 230 are respectively disposed at opposite ends of the first magnetic part 210 to achieve magnetic shielding 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.

[0035] In one example, the connecting part 220, the first magnetic part 210, and the mounting part 230 can be arranged sequentially along the length direction Y of the magnetic worktable to adapt to applications requiring high travel in the width direction X. Alternatively, these three parts can also be arranged sequentially along the width direction X of the magnetic worktable to adapt to applications requiring high travel in the length direction Y.

[0036] As shown in Figures 1, 2 and 5, in one possible embodiment, the magnetic stage 200 further includes a magnetic shielding member 240 wrapped around the outside of the first magnetic part 210, with both ends of the magnetic shielding member 240 connected to the connecting part 220 and the mounting part 230, respectively.

[0037] 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 combination component including at least a first magnetic part 210, a connecting part 220, a mounting part 230, and a magnetic shielding component 240. The magnetic shielding component 240 can be a long strip plate, which can be fastened to the outer wall of the first magnetic part 210 by fasteners such as screws / bolts, or by bonding. Its two ends abut against the connecting part 220 and the mounting part 230 respectively, so as to achieve magnetic shielding protection for the two side walls of the first magnetic part 210, so that only the magnetic suction surface of the magnetic suction table 200 maintains magnetism, further improving the safety of the magnetic suction operation of the magnetic suction table 200. In addition, the setting of the magnetic shielding component 240 allows multiple magnetic worktables to operate in the same space, isolating the magnetic interference between multiple magnetic worktables and improving the safety of operation.

[0038] As shown in Figures 1, 2 and 5, in one possible embodiment, the first magnetic part 210 includes a plurality of iron parts 211, a plurality of copper magnetic parts 212 and a connector 213. In the direction from the connecting part 220 to the mounting part 230, one iron part 211 and one copper magnetic part 212 are alternately arranged. The connector 213 passes through the connecting part 220 and the first magnetic part 210 in sequence and is inserted into the mounting part 230.

[0039] In this embodiment, the specific configuration of the first magnetic part 210 is optimized. Specifically, the first magnetic part 210 is configured as a combination component including at least a plurality of iron parts 211, a plurality of copper magnetic parts 212, and a connector 213. The iron parts 211 can be long plate structures, and the copper magnetic parts 212 can be long plate structures with a thickness and length similar to the iron parts 211. Thus, the iron parts 211 and copper magnetic parts 212 can be staggered in the direction from the connecting part 220 to the mounting part 230 to form a near-quadrilateral structure. The connector 213 can be a long-shaft screw that passes through the connecting part 220 and sequentially through the staggered quadrilateral structure of the iron parts 211 and copper magnetic parts 212, and finally inserts into the mounting part 230 to achieve the connection and fastening of the magnetic chuck 200 in this direction, thereby improving the structural stability and reliability of the magnetic chuck 200. The first magnetic part 210 provided in this example has a stable structure and high reliability.

[0040] In one possible implementation, the first magnetic part 210 further includes a plurality of first magnets 214, at least one of which is fitted into a mounting hole in the copper magnetic component 212. Multiple first magnets 214 can be provided, with one first magnet 214 corresponding to one second magnet 320. This increases the magnetic attraction force of the first magnets 214 and the second magnets 320, at least in terms of quantity, thereby improving the magnetic attraction and fixation effect of the magnetic worktable.

[0041] As shown in Figures 1 to 3 and Figure 5, in one possible embodiment, the support base 100 includes a base body 110 and a first locking member (not shown in the figure). The base body 110 is provided with a connection notch 111, which is located on the outside of the magnetic suction table 200. The first locking member connects the base body 110 to the processing device through the connection notch 111.

[0042] In this embodiment, the specific configuration of the support base 100 is optimized. Specifically, the support base 100 is configured as a combined component including at least a base body 110 and a first locking member. The base body 110 can be a thin plate structure, which can support the magnetic suction table 200 and the second magnetic component 300, providing a stable magnetic attraction environment for the workpiece to be processed; it can also cooperate with the magnetic suction table 200 to provide a relatively independent working environment for the second magnetic component 300 and the magnetic switch component 400, reducing external environmental interference and improving the control accuracy of magnetic on / off and the safety of magnetic attraction fixation. The first locking member can be a fastener such as a long screw or bolt, with a limiting head. When it is screwed onto 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 base body 110 and are inserted into the processing device. At the same time, the head is locked above the connection notch 111, improving the tightness and reliability of the connection between the support base 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; in addition, the connection notch 111 provided on it can effectively reduce the overall weight, which is conducive to the thin and light layout of the magnetic worktable.

[0043] As shown in Figures 2, 3 and 5, in one possible embodiment, the magnetic worktable further includes a second locking member 600, through which the magnetic suction table 200 is connected and fastened to the support base 100.

[0044] In this embodiment, the specific configuration of the magnetic worktable is further optimized. Specifically, the magnetic worktable is configured as a combination of at least a support base 100, a magnetic suction platform 200, a second magnetic component 300, a magnetic switch component 400, and a second locking component 600. The second locking component 600 can be a fastener such as a long screw or a long bolt. The second locking component 600 can pass through the magnetic suction platform 200 and be inserted into the support base 100 in sequence to achieve a secure connection between the magnetic suction platform 200 and the support base 100. The connection is highly reliable and the overall structure is stable.

[0045] It is understood that the magnetic stage 200 is provided with a through hole extending Z along its thickness direction, and an internal thread structure can be provided in the through hole; at the same time, the support base 100 is provided with a recessed fixing hole extending Z along its thickness direction, which corresponds to the through hole and can be provided with an internal thread structure. In this way, by providing a corresponding external thread structure on the outer wall of the second locking member 600, the connection between the second locking member 600 and the magnetic stage 200, the second locking member 600 and the support base 100, and the magnetic stage 200 and the support base 100 can be further strengthened, thereby further improving the overall structural stability and reliability of the magnetic worktable.

[0047] The magnetic worktable provided in this embodiment has precise and stable flatness, strong magnetic attraction to the workpiece, high operational reliability, and a higher safety factor. Furthermore, it has a larger market share in the thickness direction Z, which is beneficial for achieving a thinner and lighter design in processing equipment. The magnetic worktable can realize the machining of various ultra-precision molds / products with high overall machining accuracy and high product yield.
