Description

Technical Field

[0001] The present invention relates to the technical field of electroplating equipment, in particular to a multi-station high-precision superhard grinding wheel profiling electroplating equipment. Background Art

[0002] In modern manufacturing, high-precision, superhard electroplated grinding wheels, due to their exceptional performance, are widely used in aerospace, precision machining, and other fields. They are used to machine difficult-to-machine workpieces requiring extremely high precision, such as aerospace precision gears. These grinding wheels use a metal substrate, with superhard abrasives such as diamond or CBN deposited onto the surface through an electroplating process. The abrasive is typically a single layer, and the grinding wheel linear speed is ≥30m / s. They can control workpiece shape errors to within 2μm. Therefore, stringent requirements are placed on the uniformity of the abrasive and the bonding strength of the coating.

[0003] The manufacture of electroplated grinding wheels mainly includes process steps such as pre-plating, sanding and thickening, and each step has extremely strict time control. However, the industry currently mostly uses manual operation for electroplating. This traditional method is significantly affected by the workers' technical level and working status. It is difficult to ensure the consistency of the time in each process step for the same specifications and batches of grinding wheels, resulting in uneven thickness of pre-plating and thickening layers. At the same time, due to the differences in the distance between different parts of the grinding wheel base and traditional anodes (such as nickel plates), the pre-plating and thickening thickness of different parts of the base are also inconsistent within the same time period. Uneven coating thickness will seriously affect the bonding strength between the coating and the base, reducing the performance of the grinding wheel.

[0004] Furthermore, during manual sanding, different workers employ slightly different techniques, resulting in large variations in abrasive spacing and uneven abrasive distribution on grinding wheels of the same specification. Insufficient coating adhesion and uneven abrasive distribution can cause high-precision, superhard electroplated grinding wheels to rapidly degrade in accuracy during use, significantly shortening their lifespan. Furthermore, manual operation offers low production efficiency, making it difficult to meet growing production demands. Therefore, there is an urgent need to develop a new type of electroplating equipment to address these existing issues and improve the production quality and efficiency of high-precision, superhard electroplated grinding wheels. Summary of the Invention

[0005] The purpose of the present invention is to provide a multi-station high-precision super-hard grinding wheel profiling electroplating equipment to solve the problem that the traditional method proposed in the above background technology is significantly affected by the workers' technical level and working status, and it is difficult to ensure the consistency of time in each process link of the same specification and batch of grinding wheels, resulting in uneven thickness of the pre-plating layer and the thickened plating layer.

[0006] To achieve the above-mentioned purpose, the present invention provides a multi-station high-precision superhard grinding wheel profile electroplating equipment, including a frame, a lifting mechanism installed on the frame by screws, the lifting mechanism installed with a driving mechanism and a profile electroplating mechanism and several belts C by screws, the frame is provided with a plating tank, the lifting mechanism drives the profile electroplating mechanism to perform lifting movement into or out of the plating tank, and the driving mechanism drives the profile electroplating mechanism to operate through belt C.

[0007] This setup uses a frame as the basic support structure for the entire equipment. The lifting mechanism is connected to it via screws, providing a stable mounting platform. The lifting mechanism is then screwed to the drive mechanism, the profile plating mechanism, and several belts. The plating tank is mounted on the frame. When the lifting mechanism is in operation, it uses mechanical transmission principles to drive the profile plating mechanism vertically, allowing it to enter and exit the plating tank accurately. Once the drive mechanism is activated, it is connected to the profile plating mechanism via belts. Based on the principle of belt drive, this transmits driving force to the profile plating mechanism, driving its operation.

[0008] As a preferred solution of the present invention, the lifting mechanism includes left-right symmetrical guide rail mounting plates, a main mounting plate is arranged between the guide rail mounting plates, a guide rail assembly is installed on the guide rail mounting plate, a slider is slidingly arranged on the guide rail assembly, the slider is connected and fixed to the main mounting plate through the slider mounting plate, the guide rail mounting plate is fixed to the frame by screws, and the guide rail mounting plate is provided with a pin for limiting the slider.

[0009] This setup features symmetrical guide rail mounting plates for the lifting mechanism, providing guidance and support for the overall structure. A main mounting plate is located between the two. The guide rail assembly is mounted on the guide rail mounting plates, forming a sliding pair with the slider, leveraging the slider's sliding properties on the guide rails to achieve a removable connection. The slider is secured to the main mounting plate via the slider mounting plate, ensuring the main mounting plate moves with the slider. The guide rail mounting plate is secured to the frame with screws, ensuring accurate and stable installation of the lifting mechanism on the frame. Pins located on the guide rail mounting plate limit the slider's position.

[0010] As a preferred solution of the present invention, the lifting mechanism also includes a ball screw, a screw nut is installed on the ball screw, the screw nut is connected to the main mounting plate through a nut mounting plate, the ball screw is driven to rotate by the lifting motor, driving the main mounting plate to move up and down, the lifting motor is installed on the screw mounting plate through the lifting motor seat, the output shaft of the lifting motor is connected to the ball screw through a coupling, and the two ends of the ball screw are fixed to the screw mounting plate through screw mounting seat A and screw mounting seat B.

[0011] This setup uses a ball screw as the core transmission component of the lifting mechanism. The screw nut attached to the ball screw is connected to the main mounting plate via a nut mounting plate. When the lifting motor is started, the output shaft rotates, transmitting torque to the ball screw through a coupling, causing the ball screw to rotate. The screw nut and the ball screw threads cooperate to drive the main mounting plate to move up and down along the axis of the ball screw. The lifting motor is mounted on the screw mounting plate via the lifting motor mount, ensuring stable motor installation. The ends of the ball screw are secured to the screw mounting plate via screw mounting block A and screw mounting block B, ensuring stability during rotation.

[0012] As a preferred solution of the present invention, the driving mechanism includes a driving mounting plate, on which a driving motor and several driving shaft assemblies are mounted. The driving motor is mounted on the driving mounting plate through the driving motor plate. The output shaft of the driving motor drives a driving shaft assembly to rotate through a first pulley and belt A. The driving shaft assemblies are transmitted to each other through belt B, and the driving shaft assembly is fixed to the driving mounting plate through a mounting seat.

[0013] The drive mounting plate in this configuration serves as the mounting carrier for the drive mechanism. The drive motor is mounted to the drive mounting plate via the drive motor plate, ensuring a secure motor installation. When the drive motor is started, the output shaft rotates the first pulley, which in turn drives the connected drive shaft assembly via belt A. Belt B transmits power to each drive shaft assembly, utilizing the friction of the belt to transmit power and enable synchronized rotation of multiple drive shaft assemblies. The drive shaft assemblies are secured to the drive mounting plate via mounting brackets, ensuring stability during operation.

[0014] As a preferred embodiment of the present invention, the drive shaft assembly includes a drive shaft, on which three second pulleys are mounted, two of which are used to transmit belt B between the drive shaft assemblies, and the other is used to drive the contour electroplating mechanism.

[0015] This setup features secondary pulleys mounted on both ends of the drive shaft within the drive shaft assembly, providing a belt drive connection to other components. Spacer rings and bushings are placed between the secondary pulleys and the mounting base. The spacer rings provide axial positioning and spacing, while the bushings reduce friction between the drive shaft and the mounting base, improving transmission efficiency. The drive shaft is rotationally connected to the mounting base via bearings. The rolling friction characteristics of the bearings allow the drive shaft to rotate flexibly within the mounting base, minimizing energy loss.

[0016] As a preferred solution of the present invention, the contoured electroplating mechanism is provided with an electroplating vertical plate, an electroplating horizontal plate is installed on the upper end of the electroplating vertical plate, the electroplating horizontal plate is driven to rise and fall by a lifting mechanism, an electroplating shaft is installed on one side of the lower end of the electroplating vertical plate, a third pulley is installed on the electroplating shaft, the third pulley is connected to the second pulley through belt C transmission, an electroplating sleeve is provided on the electroplating shaft near the electroplating vertical plate, and an electroplating spacer ring and an electroplating bushing are provided between the electroplating sleeve and the third pulley.

[0017] This configuration features a horizontal plate mounted on the upper portion of the vertical plate of the profiling plating mechanism. This plate is raised and lowered by a lifting mechanism, thereby achieving the complete mechanism's elevation. A plating shaft is mounted on one side of the lower end of the vertical plate, and a third pulley is attached to the shaft. This third pulley is connected to the second pulley on the drive shaft assembly via belt C. When the drive shaft assembly is in operation, belt C drives the shaft. A plating sleeve is installed near the vertical plate on the shaft. Between the sleeve and the third pulley are a plating spacer ring and a plating bushing for positioning and friction reduction.

[0018] As a preferred embodiment of the present invention, a cathode sleeve and an axial nut are provided at the other end of the electroplating shaft, two contoured anodes are provided on the cathode sleeve, and an anode cover and a buckle are provided on the contoured anode. In the contoured electroplating mechanism, only the cathode sleeve and the contoured anode are conductive, and the rest are made of non-conductive materials.

[0019] This setup places a cathode sleeve and axial nut at the other end of the plating shaft for mounting components such as the contoured anode. Two contoured anodes are mounted on the cathode sleeve and secured to the sleeve with clips. Circumferential clamping is achieved by pressing against the contoured anode's edge (B). The anode cover is used to block the contoured anode's injection hole to prevent the plating solution or the plating solution-abrasive mixture from escaping. The anode cover is secured by edge (A). In the contoured electroplating mechanism, only the cathode sleeve and contoured anode are made of conductive materials, while the remaining components are made of non-conductive materials. This ensures that the current can form an effective circuit between the cathode and anode for electroplating operations.

[0020] As a preferred embodiment of the present invention, the contoured anode is provided with an anode circular hole for installing the anode wire and a liquid injection hole for realizing the entry and exit of the plating solution and the plating solution abrasive mixture; the contoured anode is provided with an edge A and an edge B, and the clip clamps the two contoured anodes circumferentially to the cathode sleeve and the axial nut by pressing the edge B; the contoured anode is provided with an arc-shaped inner wall, which forms a cavity with the arc area of ​​the grinding wheel to be plated, and the arc-shaped inner wall is equidistant from the arc area to be plated.

[0021] This configuration features a circular anode hole for mounting the anode wire, connecting it to the positive terminal of the power supply and providing the anodic current for electroplating. A liquid injection hole allows for the entry and exit of the plating solution and the abrasive-abrasive mixture. The edges of the contoured anode are clamped together, securing the two contoured anodes circumferentially to the cathode sleeve and axial nut. The arc-shaped inner wall of the contoured anode forms a cavity with the arc area of ​​the grinding wheel to be plated, and the two are spaced equidistantly, ensuring a more uniform electric field distribution during the electroplating process.

[0022] As a preferred solution of the present invention, the cathode sleeve is provided with a cathode circular hole for installing the cathode wire, and is provided with an inner arc surface with a non-conductive coating.

[0023] This setup features a circular hole in the cathode sleeve for mounting a cathode lead, which connects to the negative terminal of the power supply, making the sleeve the cathode portion of the electroplating circuit. A non-conductively coated inner arc surface prevents contact between the sleeve and the contoured anode, ensuring current is concentrated in the area to be plated opposite the contoured anode, improving electroplating accuracy and efficiency.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. This multi-station, high-precision, super-hard grinding wheel profiling electroplating equipment changes the traditional manual sanding method by utilizing the coordinated rotation of the profiling anode and grinding wheel within the profiling electroplating mechanism. During operation, the profiling anode and grinding wheel rotate in a specific pattern, allowing the abrasive to be evenly adsorbed onto the pre-plated coating under the combined effects of centrifugal force and electroplating force. This effectively avoids the wide spacing and uneven distribution of abrasives on the same specification grinding wheels, which can occur due to differences in manual sanding techniques, and ensures abrasive uniformity throughout the sanding process.

[0026] 2. This multi-station, high-precision, superhard grinding wheel profiling electroplating equipment utilizes a contoured anode design. Its arc-shaped inner wall forms a cavity with equal spacing from the arc area of ​​the grinding wheel to be plated. This ensures that the distance from the contoured anode to each part of the grinding wheel substrate is essentially uniform. During the pre-plating and thickening processes, current distribution is more uniform, allowing nickel ions to be deposited evenly on the grinding wheel substrate surface. This solves the problem of uneven coating thickness caused by varying distances between the substrate and conventional anodes, improving coating adhesion and grinding wheel performance.

[0027] 3. This multi-station, high-precision, super-hard grinding wheel profile plating equipment features automatic control. Through the coordinated operation of the lifting mechanism, drive mechanism, and profile plating mechanism, the equipment precisely controls the time required for each process, including pre-plating, sanding, and thickening. Compared to manual operation, which is significantly affected by the worker's condition and suffers from imprecise time control, this equipment ensures consistent time for each process step for the same specification and batch of grinding wheels. This reduces labor input, enabling a single person to operate more equipment and lowering production costs.

[0028] 4. The multi-station design is a highlight of this multi-station high-precision super-hard grinding wheel profiling electroplating equipment. By performing electroplating processing at multiple stations simultaneously, the overall processing time is greatly shortened. Compared with traditional single-station equipment, the electroplating processing efficiency can be doubled, meeting the growing production needs and enhancing the company's competitiveness in the market.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] The present invention provides a multi-station high-precision super-hard grinding wheel profiling electroplating equipment, such as Figure 1 As shown, the frame 1 includes a lifting mechanism 2 installed by screws, the lifting mechanism 2 is installed with a driving mechanism 3 and a contour electroplating mechanism 4 and several belts 5 by screws, the frame 1 is provided with a plating tank 6, the lifting mechanism 2 drives the contour electroplating mechanism 4 to move up and down to enter or leave the plating tank 6, and the driving mechanism 3 drives the contour electroplating mechanism 4 to operate through the belts 5.

[0042] The frame 1 serves as the basic supporting structure of the entire equipment and is connected to the lifting mechanism 2 by screws to provide a stable installation platform. The lifting mechanism 2 is installed with the driving mechanism 3, the profile electroplating mechanism 4 and several belts 5 by screws. The plating tank 6 is set on the frame 1. When the lifting mechanism 2 is working, it uses the principle of mechanical transmission to drive the profile electroplating mechanism 4 to perform lifting and lowering movements in the vertical direction so that it can accurately enter and exit the plating tank 6. After the driving mechanism 3 is started, it is connected to the profile electroplating mechanism 4 through the belt 5 and, according to the belt transmission principle, transmits the driving force to the profile electroplating mechanism 4 to drive its operation. The connection method between the frame 1 and each mechanism ensures the stability of the overall structure of the equipment and provides a basis for the normal operation of each mechanism. The lifting mechanism 2 realizes the function of the profile electroplating mechanism 4 entering and exiting the plating tank 6, so that the electroplating process can be carried out in an orderly manner under a suitable environment, which is convenient for electroplating processing of the grinding wheel. The driving mechanism 3 drives the contour electroplating mechanism 4 through belt transmission, providing necessary power support for the electroplating process, ensuring the smooth progress of the electroplating process, and meeting the basic operating requirements of multi-station high-precision superhard grinding wheel contour electroplating equipment.

[0043] In this embodiment, Figure 2 As shown, the lifting mechanism 2 includes left-right symmetrical guide rail mounting plates 201, a main mounting plate is arranged between the guide rail mounting plates 201, a guide rail assembly 202 is installed on the guide rail mounting plates 201, a slider 2021 is slidingly arranged on the guide rail assembly 202, the slider 2021 is connected and fixed to the main mounting plate 213 through the slider mounting plate 214, and is limited by the pin 204, and the guide rail mounting plate 201 is fixed to the frame 1 by screws.

[0044] The symmetrical guide rail mounting plate 201 of the lifting mechanism 2 provides guidance and support for the entire structure, with a main mounting plate 213 positioned between them. The guide rail assembly 202 is mounted on the guide rail mounting plate 201. This assembly forms a sliding pair with the slider 2021, leveraging the sliding properties of the slider 2021 on the guide rail to achieve a removable connection. The slider 2021 is secured to the main mounting plate 213 via the slider mounting plate 214, ensuring that the main mounting plate 213 moves with the slider 2021. The guide rail mounting plate 201 is secured to the frame 1 with screws, ensuring the accuracy and stability of the installation of the lifting mechanism 2 on the frame 1.

[0045] The cooperation between the guide rail assembly 202 and the slider 2021 provides precise guidance for the movement of the lifting mechanism 2, so that the main mounting plate 213 remains stable during the lifting process, avoiding shaking and deviation, thereby ensuring that the driving mechanism 3 and the contour electroplating mechanism 4 installed on the main mounting plate 213 can be accurately lifted and lowered, improving the accuracy and stability of the equipment operation, and is conducive to improving the quality and reliability of the electroplating process.

[0046] Specifically, such as Figure 2As shown, the lifting mechanism 2 also includes a ball screw 211, on which a screw nut 2111 is installed. The screw nut 2111 is connected to the main mounting plate through a nut mounting plate 212. The ball screw 211 is driven to rotate by the lifting motor 207, driving the main mounting plate 213 to move up and down. The lifting motor 207 is installed on the screw mounting plate 205 through the lifting motor seat 206. The output shaft of the lifting motor 207 is connected to the ball screw 211 through a coupling 208. Both ends of the ball screw 211 are fixed to the screw mounting plate 205 through a screw mounting seat A 209 and a screw mounting seat B 210. The guide rail mounting plate 201 and the screw mounting plate 205 are mounted on the frame 1 by screws.

[0047] The ball screw 211 serves as the core transmission component of the lifting mechanism 2. The screw nut 2111 installed thereon is connected to the main mounting plate 213 via the nut mounting plate 212. After the lifting motor 207 is started, the output shaft rotates, and the torque is transmitted to the ball screw 211 through the coupling 208, causing the ball screw 211 to rotate. Under the action of the screw nut 2111 and the threaded cooperation of the ball screw 211, the screw nut 2111 drives the main mounting plate 213 to perform lifting motion along the axial direction of the ball screw 211. The lifting motor 207 is installed on the screw mounting plate 205 through the lifting motor seat 206 to ensure the stability of the motor installation. The two ends of the ball screw 211 are fixed to the screw mounting plate 205 through the screw mounting seat A 209 and the screw mounting seat B 210 to ensure the stability of the ball screw 211 during rotation. The ball screw 211 transmission system offers high precision, high efficiency, and high load capacity. It precisely controls the position and speed of the main mounting plate 213, enabling the profile plating mechanism 4 to accurately enter and exit the plating tank 6 and maintain a stable position during the plating process. This meets the stringent positional accuracy requirements of high-precision, super-hard grinding wheel profile plating. Furthermore, this transmission system can withstand high loads, ensuring the reliability of the equipment during long-term operation.

[0048] Further, such as Figure 3 As shown, the driving mechanism 3 includes a driving mounting plate 301, on which a driving motor 303 and several driving shaft assemblies 306 are installed. The driving motor 303 is installed on the driving mounting plate 301 through the driving motor plate 302. The output shaft of the driving motor 303 drives a driving shaft assembly 306 to rotate through the first pulley 304 and the belt A 305. The driving shaft assemblies 306 are transmitted to each other through the belt B 307. The driving shaft assembly 306 is fixed to the driving mounting plate 301 through the mounting seat 308.

[0049] Drive mounting plate 301 is the installation carrier of drive mechanism 3, and drive motor 303 is installed on drive mounting plate 301 by drive motor plate 302, guarantees that motor installation is firm.After drive motor 303 starts, output shaft drives first pulley 304 to rotate, and first pulley 304 drives connected drive shaft assembly 306 to rotate by belt first 305.Transmission is carried out by belt second 307 between each drive shaft assembly 306, utilizes the friction force of belt to transmit power, makes multiple drive shaft assembly 306 can rotate synchronously.Drive shaft assembly 306 is fixed on drive mounting plate 301 by mounting base 308, guarantees its stability in the working process.This design of drive mechanism 3 can provide stable and adjustable driving force for profiling electroplating mechanism 4, by the combination of different pulleys and belt transmission, can flexibly adjust the rotating speed of drive shaft assembly 306, to adapt to the electroplating demand of different size grinding wheels, improve the versatility and adaptability of equipment. At the same time, the multiple drive shaft assemblies 306 work together to ensure the smooth operation of the contour electroplating mechanism 4, which is beneficial to improving the electroplating quality.

[0050] Further, such as Figure 3 As shown, the drive shaft assembly 306 includes a drive shaft 3061, and three second pulleys 3062 are installed on the drive shaft 3061, two of which are used to transmit the belt B 307 between the drive shaft assemblies 306, and the other is used to drive the contour plating mechanism 4 to work.

[0051] The drive shaft 3061 in the drive shaft assembly 306 is installed with three second pulleys 3062 and is used to carry out belt transmission connection with other components. Between the second pulley 3062 and the mounting base 308, a spacer ring 3063 and a bushing 3064 are set. The spacer ring 3063 plays the role of axial positioning and spacing, and the bushing 3064 can reduce the friction between the drive shaft 3061 and the mounting base 308, thereby improving transmission efficiency. The drive shaft 3061 is rotatably connected to the mounting base 308 through a bearing. The rolling friction characteristics of the bearing are utilized to enable the drive shaft 3061 to flexibly rotate in the mounting base 308, thereby reducing energy loss. The provision of the spacer ring 3063, bushing 3064 and bearing ensures the normal operation of the drive shaft assembly 306, reduces the wear and tear between the components, and improves the service life and transmission efficiency of the drive shaft assembly 306. The stable rotation of the drive shaft 3061 can ensure the stability of the belt transmission, thereby ensuring the stability and reliability of the operation of the profile electroplating mechanism 4, and providing stable power output for high-precision electroplating.

[0052] Further, such as Figure 4 、 Figure 6As shown, the contour plating mechanism 4 is provided with a plating vertical plate 402, and a plating horizontal plate 401 is installed on the upper end of the plating vertical plate 402. The plating horizontal plate 401 is lifted and lowered by the lifting mechanism 2. A plating shaft 404 is installed on one side of the lower end of the plating vertical plate 402. A third pulley 405 is installed on the plating shaft 404. The third pulley 405 is connected to the second pulley 3062 through a belt C 5. A plating sleeve 403 is provided on the plating shaft 404 near the plating vertical plate 402. A plating spacer ring 406 and an electroplating bushing 407 are provided between the plating sleeve 403 and the third pulley 405.

[0053] The electroplating risers 402 upper ends of the profiling electroplating mechanism 4 are provided with an electroplating cross plate 401, which is driven to rise and fall by the lifting mechanism 2, thereby realizing the lifting of the entire profiling electroplating mechanism 4. A plating shaft 404 is installed on one side of the lower end of the electroplating risers 402. The third pulley 405 is installed on the electroplating shaft 404. The third pulley 405 is connected to the second pulley 3062 on the drive shaft assembly 306 by a belt C 5 transmission. When the drive shaft assembly 306 is running, the electroplating shaft 404 is driven to rotate by the belt C 5. An electroplating sleeve 403 is provided near the electroplating risers 402. Between the electroplating sleeve 403 and the third pulley 405, an electroplating spacer ring 406 and an electroplating bushing 407 are provided to play the role of positioning and reducing friction. This structural design enables the profiling electroplating mechanism 4 to realize accurate lifting and stable rotation under the coordinated action of the lifting mechanism 2 and the drive mechanism 3. The rotation of the electroplating shaft 404 drives the cathode sleeve 408 and other components connected thereto to rotate, providing necessary motion conditions for contour electroplating, ensuring that the relative motion between the cathode and anode is stable during the electroplating process, which is beneficial to improving the uniformity and quality of the electroplating layer.

[0054] Further, such as Figure 4 、 Figure 5 、 Figure 6 As shown, the other end of the electroplating shaft 404 is provided with a cathode sleeve 408 and an axial nut 410, and two contoured anodes 409 are provided in the cathode sleeve 408. The contoured anodes 409 are provided with an anode cover 411 and a buckle 412. In the contoured electroplating mechanism 4, only the cathode sleeve 408 and the contoured anode 409 are conductive, and the rest are made of non-conductive materials.

[0055] Electroplating shaft 404 other end is provided with cathode sleeve 408 and axial nut 410, is used for installing parts such as profiling anode 409.Two profiling anodes 409 are set in the cathode sleeve 408, profiling anode 409 is fixed on the cathode sleeve 408 by snap 412, realizes circumferential clamping by the edge second 4094 that compresses profiling anode 409.In the profiling electroplating mechanism 4, only cathode sleeve 408, profiling anode 409 adopt conductive material, and the remainder adopts non-conductive material, guarantees that electric current can form effective loop between cathode and anode, carries out electroplating operation.This structural design has guaranteed the firmness that profiling anode 409 is installed on cathode sleeve 408, makes it can not be displaced in the rotation process.Simultaneously, by to the reasonable selection of conductive material and non-conductive material, can accurately control the path of electric current, improve electroplating efficiency and quality, avoid electric current leakage to have a bad influence on equipment and electroplating process.

[0056] As a preferred embodiment of the present invention, Figure 4 As shown, the contoured anode 409 is provided with an anode circular hole 4091 for installing the anode wire, and is provided with a liquid injection hole 4092 to realize the entry and exit of the plating solution and the plating solution abrasive mixture; the contoured anode 409 is provided with an edge A 4093 and an edge B 4094, and the buckle 412 clamps the two contoured anodes 409 circumferentially on the cathode sleeve 408 and the axial nut 410 by pressing the edge B 4094, and the edge A 4093 is clamped and fixed by the anode cover 411; the contoured anode 409 is provided with an arc-shaped inner wall 4095, which forms a cavity 8 with the arc area 71 to be plated of the grinding wheel 7, and the arc-shaped inner wall 4095 is equidistant from the arc area 71 to be plated.

[0057] The profiling anode 409 is provided with an anode circular hole 4091 for installing an anode wire, realizing connection with the positive pole of the power supply, and providing an anode current for electroplating. The liquid injection hole 4092 is then used to realize the in and out of the plating solution and the plating solution abrasive mixture, ensuring the circulation of the plating solution and the replenishment of the abrasive in the electroplating process. The edge first 4093 and edge second 4094 of the profiling anode 409 are compressed by the anode cover 411 and the buckle 412, thereby the two profiling anodes 409 are circumferentially clamped on the cathode sleeve 408 and the axial nut 410. The arc-shaped inner wall 4095 of the profiling anode 409 and the arc area 71 to be plated of the grinding wheel 7 surround the cavity 8, and the two are equidistant, so that in the electroplating process, the electric field distribution is more uniform. The design of the anode circular hole 4091 and the liquid injection hole 4092 meets the demand of the electroplating process for current introduction and plating solution circulation, and guarantees the normal carrying out of the electroplating process. The mounting method of the contoured anode 409 and cathode sleeve 408 ensures structural stability. The cavity 8 formed by the equally spaced arc-shaped inner walls 4095 and the arc area to be plated 71 can evenly distribute the electric field on the surface of the grinding wheel 7 to be plated, which helps to improve the consistency of the coating thickness and the uniformity of the abrasive distribution, thereby improving the quality of the electroplated grinding wheel.

[0058] As a preferred scheme of the present application, as shown in Figure 7 The cathode sleeve 408 is provided with a cathode hole 4081 for installing a cathode wire, and an inner arc surface 4082 with a non-conductive coating is arranged.

[0059] The cathode sleeve 408 is provided with a cathode hole 4081 for installing a cathode wire, and an inner arc surface 4082 with a non-conductive coating is arranged.

[0060] The cathode hole 4081 facilitates the connection of the cathode wire, ensuring the stable introduction of the cathode current. The design of the inner arc surface 4082 with a non-conductive coating effectively avoids the dispersion of the current, making the electroplating process more concentrated and efficient, and further improving the plating layer quality and the stability of the electroplating process.

[0061] The multi-station high-precision super-hard grinding wheel profiling electroplating equipment of the present application is used as follows: first, the equipment origin is located above the plating tank 6, the lifting motor 207 is reset, and the profiling electroplating mechanism 4 is located at the origin position. The operator installs the cathode and anode wires, passes the two anode wires through the anode holes 4091 of the profiling anodes 409 respectively and connects the positive pole of the power supply, and passes the cathode wire through the cathode hole 4081 of the cathode sleeve 408 and connects the negative pole of the power supply. The plating solution is injected into the plating tank 6, and the plating solution height reaches 80% of the plating tank. At the same time, the non-plating area of the grinding wheel base is covered with insulating adhesive tape to prevent the non-plating area from being electroplated.

[0062] The anode cover 411 above the contoured anode 409 is opened, and the plating solution is filled into the contoured anode 409 through the liquid injection hole 4092. The anode cover 411 is then closed. The lifting motor 207 is activated, which drives the ball screw 211 to rotate via the coupling 208. The screw nut 2111 moves on the ball screw 211, driving the main mounting plate 213, the drive mechanism 3 fixed thereto, and the contoured electroplating mechanism 4 to descend, causing the contoured anode 409 and the grinding wheel to enter the plating tank 6. The anode and cathode wires are connected, and the drive motor 303 is activated. The drive motor 303 drives a drive shaft assembly 306 to rotate via the first pulley 304 and belt A 305. The drive shaft assemblies 306 are then synchronized by belt B 307. Finally, the plating shaft 404 is driven by belt C 5, thereby rotating the contoured anode 409 and the grinding wheel. Under the action of the electric field, the nickel ions in the contoured anode 409 are oxidized and enter the plating solution, and are then evenly deposited on the grinding wheel substrate. After running for 10 minutes (which can be adjusted according to actual needs), the drive motor 303 stops, and the lifting motor 207 drives the contoured anode 409 and the grinding wheel to rise to the origin. The anode cover 411 below the contoured anode 409 is opened, and the plating solution flows out through the injection hole 4092 into the plating tank 6. The pre-plating is completed, and the equipment notifies the operator through lights and sounds.

[0063] Open the anode cover 411 above the profiling anode 409, fill with the plating solution mixture of mixed abrasive in the profiling anode 409, close the anode cover 411.Restart lifting motor 207 again, make profiling anode 409 and emery wheel descend in the plating tank 6, connect anode and cathode lead, drive motor 303 drives profiling anode 409 and emery wheel to rotate.In the rotation process, abrasive, under the effect of electric field force and plating solution flow, is evenly adsorbed on the coating after pre-plating.After running 20 minutes (can be adjusted according to actual demand), abrasive is evenly fixed on the coating, and drive motor 303 stops, and lifting motor 207 drives profiling anode 409 and emery wheel to rise to origin.Open the anode cover 411 below, plating solution and non-absorbed abrasive flow out into plating tank 6 by liquid injection hole 4092, and upper sand is finished, and equipment prompts the operator by light and sound.

[0064] The anode cover 411 above the contoured anode 409 is opened, and the contoured anode 409 is filled with plating solution. The anode cover 411 is then closed. The lifting motor 207 lowers the contoured anode 409 and the grinding wheel into the plating tank 6. The anode and cathode wires are connected, and the drive motor 303 drives the contoured anode 409 and the grinding wheel. The nickel ions in the contoured anode 409 are oxidized and gradually and evenly deposited on the grinding wheel substrate, further thickening the coating. After 60 minutes of operation (which can be adjusted based on actual needs), the drive motor 303 stops, and the lifting motor 207 raises the contoured anode 409 and the grinding wheel to their starting point. The anode cover 411 below is opened, and the plating solution flows completely out through the injection hole 4092 into the plating tank 6. The thickening is complete, and the equipment prompts the operator with lights and sounds.

[0065] If the device is designed for multiple stations, after the above-mentioned single station completes the electroplating process, the same pre-plating, pre-plating, sanding, thickening and other process operations can be performed on the sand wheels of other stations simultaneously or sequentially, greatly improving the electroplating processing efficiency.
