Description

Technical Field

[0001] This invention relates to an automated grinding equipment for high-stability ferrite cores, belonging to the technical field of machine tools and devices used for grinding or polishing. Background Technology

[0002] Ferrite cores are indispensable key components in electronic devices and are widely used in communications, new energy, automotive electronics, and other fields. With the rapid development of electronic technology, increasingly stringent requirements are being placed on the dimensional accuracy, surface smoothness, and stability of ferrite cores. In traditional production processes, the grinding and processing of ferrite cores largely relies on manual operation or semi-automated equipment, resulting in low processing efficiency, poor product consistency, and high labor intensity.

[0003] Especially for hollow tubular ferrite cores, the grinding process requires ensuring the uniformity and dimensional stability of the inner and outer walls. Manual operation or semi-automated equipment struggles to precisely control the grinding force and path, easily leading to defects such as core deformation and surface scratches, severely impacting product performance. Furthermore, the debris and cooling water generated during grinding cannot be promptly managed and flow freely, not only polluting the working environment but also potentially adhering to the core surface and affecting processing quality.

[0004] Therefore, developing a device that can achieve automated, high-precision, and high-efficiency grinding, and has good chip handling capabilities, has become an urgent need in the field of ferrite core production. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this invention provides a highly stable automated ferrite core grinding equipment, which solves the problems of low processing efficiency, poor precision, low automation, and poor chip handling in common ferrite core grinding equipment.

[0006] The objective of this invention is achieved through the following technical solution: an automated grinding equipment for high-stability ferrite cores, comprising a machine cover and a flip-up top cover. A worktable is installed inside the machine cover, and two opposing three-axis displacement mechanisms are provided on the worktable. Grinding mechanisms are installed on both of the three-axis displacement mechanisms. Two multi-unit clamping mechanisms are also provided on the worktable. Chip removal components are provided on both sides of the multi-unit clamping mechanisms, and a bidirectional pressing mechanism is provided between the two multi-unit clamping mechanisms.

[0007] Furthermore, first slide rails are installed on both sides of the workbench, and strip-shaped metal pads are provided on the inner side of the first slide rails. The metal pads are installed and connected to the workbench.

[0008] Furthermore, the three-axis displacement mechanism includes a main beam frame, with support frames installed at the bottom of both ends of the main beam frame. The bottom of the support frame is slidably connected to the first slide rail via a slider. A first motor is installed on the support frame, and a first helical gear is installed at the output end of the first motor. A first helical rack is installed on the top of the metal pad. The first helical gear meshes with the first helical rack and drives the support frame to move along the X-axis.

[0009] Furthermore, a sliding bracket is provided on the outer side of the main beam frame. The sliding bracket is designed as an inverted "T". A second slide rail is installed at the farthest point of the main beam frame on the top and side, and is slidably connected to the sliding bracket by a slider. A second helical rack is installed on the other side of the top of the main beam frame away from the second slide rail. A second motor is installed on the sliding bracket. A second helical gear is installed at the output end of the second motor. The second helical gear meshes with the second helical rack and drives the sliding bracket to move along the Y-axis.

[0010] Furthermore, two second slide rails are respectively installed on the main beam frame near the diagonally opposite edge, and the sliding bracket is also equipped with a cover and conduit.

[0011] Furthermore, a lifting cylinder is installed on the side of the sliding bracket. The lifting cylinder is a vertically arranged sliding cylinder. The sliding table on the lifting cylinder is connected to the grinding mechanism and drives the grinding mechanism to move along the Z-axis.

[0012] Furthermore, the grinding mechanism includes a frame on which a vertical rotating roller is vertically mounted. The bottom of the vertical rotating roller is provided with a grinding roller and fixed by a chuck. A third motor is also mounted on the frame. The output end of the third motor is connected to the vertical rotating roller through a pair of toothed pulleys and a synchronous toothed belt.

[0013] Furthermore, vertically positioned grinding rollers are better for grinding and polishing hollow tubular ferrite cores, allowing the cores to achieve ideal dimensional accuracy, surface smoothness, and dimensional stability. However, an external cooling water supply system is required to provide additional support during the grinding process.

[0014] Furthermore, the multi-unit clamping mechanism includes a base, the top surface of which is arrayed with a plurality of clamping members, a separator is provided at the middle position of the top surface of the base and is fixed to the base by screws, both sides of the clamping members are provided with limiting guide rails and are fixed to the base by screws, and the clamping members are provided with protruding sliders on both sides that engage with the sliding grooves provided on the side of the limiting guide rails to achieve a sliding function.

[0015] Furthermore, a guide slide rod is respectively provided inside the clamping member on both sides of the separator. The guide slide rod has a fixed-distance slot. A fixed-distance round rod is provided inside the fixed-distance slot. The fixed-distance round rod is inserted and connected to the clamping member. Each clamping member is provided with a clamping slot. The clamping slots on two adjacent clamping members are set opposite each other and used in pairs. The clamping slots are in the shape of a right triangle.

[0016] Furthermore, both ends of the platform are provided with rotating rods, and the tail ends of the two rotating rods are respectively rotatably connected to the two outermost clamping members among the plurality of clamping members. A connecting member is installed at the other end of the rotating rod. A double-outlet cylinder is installed at the bottom of the worktable. The two output ends of the double-outlet cylinder are respectively connected to the two connecting members. The worktable has a square hole in the connecting member, and the radial dimension of the square hole is not less than the maximum sliding length of the connecting member.

[0017] Furthermore, by using additional feeding equipment, the cut magnetic core is placed in the clamping slots between several clamping components. Then, a double-outlet cylinder drives a rotating rod to squeeze the clamping components, causing them to slide towards the separator, thereby reducing the gap and clamping the magnetic core material. When the magnetic core needs to be removed, the operation can be reversed.

[0018] Furthermore, the bidirectional pressing mechanism includes a pair of pressure plates, with a set of L-shaped lever arms mounted on the top of each pressure plate. The other end of both sets of L-shaped lever arms is provided with a rotating shaft and connected to the end of the L-shaped lever arm. The rotating shaft is connected to the worktable through a rotating shaft seat.

[0019] Furthermore, toothed pulleys are installed on the rotating shafts corresponding to the two sets of L-shaped lever arms, and a coaxial reversing gear set is provided below the worktable.

[0020] Furthermore, the pair of pressure plates are respectively located above the two multi-unit clamping mechanisms, and the two sets of L-shaped lever arms are oriented in opposite directions.

[0021] Furthermore, rubber sheets can be optionally installed on the bottom of the pressure plate strips to prevent damage from impacts.

[0022] Furthermore, the coaxial reversing gear set includes a main gear and a pair of driven gears. The two driven gears are arranged opposite each other and are both meshed with the main gear. A fourth motor is provided on the side of the main gear. The output end of the fourth motor is connected to the main gear. All three gears are helical gears. The ends of the connecting shafts of the two driven gears are provided with toothed pulleys and are connected to the toothed pulleys mounted on the L-shaped lever arm through synchronous toothed belt transmission. All three gears and the fourth motor are connected to the bottom surface of the worktable through a bracket.

[0023] Furthermore, the fourth motor drives two sets of L-shaped lever arms to rotate synchronously and press down in two directions around the rotating shaft via a coaxial reversing gear set, pressing the magnetic core and magnetic material into the multi-unit clamping mechanism so that its bottom contacts the base to avoid shaking during grinding and affecting the processing effect.

[0024] Furthermore, the chip removal assembly includes a strip-shaped compartment, which is installed through the workbench. The top of the strip-shaped compartment is open, and several connecting pipes are fixedly installed at the bottom of the strip-shaped compartment. The inner bottom edge of the strip-shaped compartment is rounded.

[0025] Furthermore, in addition to removing debris, the chip removal component also removes cooling water, preventing cooling water from accumulating on the surface of the workbench 102. Since it is necessary to achieve the effect of simultaneous dust removal and water removal, the adsorption body adopts an industrial-grade vacuum cleaner with both dust removal and water filtration functions, and is connected to the connecting pipe via a hose.

[0026] In summary, compared with the prior art, the present invention has the following advantages: 1. In this invention, the dual grinding heads and multi-unit clamping mechanism support simultaneous processing of multiple magnetic cores, doubling the production capacity. The three-axis displacement mechanism adopts helical gear-rack transmission, which achieves precise positioning of the grinding mechanism. The response speed is significantly improved compared to conventional lead screws. Combined with the bidirectional clamping mechanism, the magnetic core is firmly clamped, effectively avoiding shaking during the grinding process. This ensures that the magnetic core obtains ideal dimensional accuracy, surface smoothness, and dimensional stability, effectively avoiding the impact of manual operation on processing accuracy and efficiency, and achieving automated and highly stable processing. 2. In the present invention, the vertical grinding roller is adapted to the tubular magnetic core structure, and the bidirectional clamping mechanism suppresses vibration, achieving a dimensional accuracy of ±0.01mm. The right-angled triangular clamping jaws adaptively lock, reducing the magnetic core breakage rate to less than 2%. 3. In the present invention, the coaxial reversing gear set ensures bidirectional clamping force synchronization, improves workpiece positioning consistency, and the chip removal component integrates coolant recovery, reducing the number of devices in a limited space and maximizing the utilization of streamlined space; 4. In the present invention, the multi-unit clamping mechanism can clamp multiple magnetic cores for processing at the same time. Combined with the automatic movement of the three-axis displacement mechanism and the automatic operation of the grinding mechanism, it greatly reduces manual intervention, increases the processing quantity per unit time, and significantly improves production efficiency. 5. In the present invention, the chip removal component can promptly remove the chips and cooling water generated during grinding, preventing them from accumulating on the worktable or adhering to the surface of the magnetic core. This not only improves the working environment but also avoids scratching the surface of the magnetic core by the chips, further ensuring the processing quality. Attached Figure Description

[0035] Combine Figures 2 to 5 As shown, a lifting cylinder 211 is installed on the side of the sliding bracket 206. The lifting cylinder 211 is a vertically set sliding cylinder.

[0037] The vertically arranged grinding roller 303 is good for grinding and polishing hollow tubular ferrite cores.

An external cooling water supply component is required to provide additional support during the grinding process.

[0038] Combine Figure 2 , Figures 6 to 8 As shown, the multi-unit clamping mechanism 4 includes a base 401. Several clamping members 402 are arranged in an array on the top surface of the base 401. A separator 403 is provided in the middle of the top surface of the base 401 and is fixed to the base 401 by screws.

The radial dimension of the square hole is not less than the maximum sliding length of the connector 410.

[0041] The cut magnetic core is placed in the clamping slots 408 between several clamping parts 402 by an additional feeding device. Then, the rotating rod 409 is driven by the double-outlet cylinder 411 to squeeze the clamping parts 402 and make them slide towards the separator 403 to reduce the gap and achieve clamping of the magnetic core material. When the magnetic core needs to be removed, the operation is reversed.

[0042] Combine Figure 2 , Figure 9 , Figure 10As shown, the bidirectional pressing mechanism 6 includes a pair of pressure plates 601.

The other end of each set of L-shaped lever arms 602 is provided with a rotating shaft 603 and connected to the end of the L-shaped lever arm 602.

Since it is necessary to achieve the effect of simultaneous dust removal and water removal, the adsorption body adopts an industrial-grade vacuum cleaner with both dust removal and water filtration functions, and is connected to the connecting pipe 502 via a hose.

[0050] Working principle: When the present invention is used, the magnetic core is placed in the clamping slot 408 of the multi-unit clamping mechanism 4 by an external feeding device. The double-outlet cylinder 411 drives the rotating rod 409 to push the clamping member 402 to slide along the limiting guide rail 404 toward the separator 403, and the magnetic core is adaptively locked by the pair of right-angled triangular slots. The fourth motor 703 drives the coaxial reverse gear set 7, which is linked by the synchronous belt to rotate the two sets of L-shaped lever arms 602 in opposite directions, driving the pressure plate 601 to press down on the top of the magnetic core and force the bottom of the magnetic core to fit against the base 401, thus eliminating grinding vibration.

[0051] The chip removal component 5 collects the chips and coolant generated during the processing through the bar bin 501, and then filters and separates them through the connecting pipe 502 by an external vacuum cleaner, keeping the workbench clean.

[0052] Two three-axis displacement mechanisms are independently controlled: X-axis: The first motor 203 drives the support frame 202 to move along the first slide rail 103 through the meshing of the first helical gear 204 and the first helical rack 205. Y-axis: The second motor 209 drives the sliding bracket 206 to move along the second slide rail 207 through the meshing of the second helical gear 210 and the second helical rack 208. Z-axis: Lifting cylinder 211 adjusts the height of grinding mechanism 3; The third motor 304 drives the vertical grinding roller 303 via a synchronous belt to perform high-precision grinding on the inner hole and outer wall of the magnetic core. During the grinding process, the external cooling water supply component provides additional cooling support, realizing asynchronous collaborative processing of the two grinding heads.
