Description

Technical Field

[0001] The present invention belongs to the technical field of electroplating, and particularly relates to a platinum plating device for double - link and multi - link guide vane blades. Background Art

[0002] Electroplating is a process of plating a thin layer of other metals or alloys on the surface of certain metals by using the electrolysis principle. It is a process of making the surface of metal or other material parts adhere to a metal film through electrolysis, so as to prevent metal oxidation (such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (such as copper sulfate), and enhance beauty, etc.

[0003] During the production process of the guide vane blades, it is necessary to platinum - plate the blades, that is, use electroplating equipment to electroplate the guide vane blades so that a platinum metal layer is plated on their surfaces. When electroplating, it is necessary to use tooling fixtures to fix and suspend the guide vane blades to keep them in a stable state during electroplating. For example, as disclosed in the Chinese patent publication No. CN214361795U in the prior art, a platinum - plating tooling for turbine blades that is easy to disassemble and clean is disclosed, including a mounting plate, a transmission groove, and a movable plate. The mounting plate is a cuboid structure and a transmission groove is opened on the bottom end surface. A lead screw is arranged inside the transmission groove. A slider is movably arranged on the outer wall of the lead screw. An activity sleeve is installed on one side end surface of the slider. The activity sleeve is a hollow rod - shaped structure and a movable plate is movably arranged inside it. One end of the movable plate away from the activity sleeve is arc - shaped, and a limiting groove is opened on the movable plate. A limiting rod is movably arranged inside the limiting groove. A pulling groove is opened beside the limiting groove, and a pulling plate connected to the limiting rod is movably arranged inside the pulling groove. This platinum - plating tooling for turbine blades that is easy to disassemble and clean is convenient to adjust the device according to the required platinum - plated turbine blades during use, and at the same time, it is convenient for operators to disassemble and clean the device.

[0004] Although the electroplating tooling in the above - mentioned prior art solves the problem of fixing and suspending the blades, due to the close arrangement and irregular contour of the blades of the double - link and multi - link guide vanes, during electroplating, it may cause a situation where a certain blade is blocked, resulting in poor electroplating effect. Therefore, an electroplating platinum device that can solve the electroplating dead - angle problem of the guide vane blades is needed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above - mentioned shortcomings of the prior art and provide a platinum - plating device for double - link and multi - link guide vane blades.

[0006] The technical solution adopted to solve the above - mentioned technical problem is:

[0007] A platinum - plating device for double - link and multi - link guide vane blades, including an electroplating tank and electrodes installed on both sides of the electroplating tank, further comprising:

[0008] A suspension assembly provided at the upper end of the electroplating tank;

[0009] A lifting block drivingly connected to the suspension assembly, a support shaft horizontally penetrating through the lifting block, and the support shaft being rotatably connected to the lifting block;

[0010] A clamping assembly connected to the end of the support shaft, the clamping assembly being located inside the electroplating tank, and the suspension assembly being used to drive the clamping assembly to move horizontally and vertically;

[0011] A flushing assembly connected to the support shaft.

[0012] Through the above technical solution, the inner ring of the guide is clamped and fixed by the clamping assembly, and then the suspension assembly drives the clamping assembly to move horizontally in the electroplating tank, so that the blades on the guide can fully contact the electroplating solution. In addition, during the horizontal reciprocating movement of the guide in the electroplating tank, the flushing assembly repeatedly deflects the electroplating solution towards the blades of the guide, so that the electroplating solution flows to contact the surfaces of all parts of the blades of the guide, thereby improving the electroplating effect of the guide blades to a certain extent.

[0013] Further, the suspension assembly includes a horizontal movement unit and a lifting unit.

[0014] Through the above technical solution, the horizontal movement unit on the suspension assembly drives the guide to move horizontally back and forth in the electroplating tank, so that the blades of the guide fully contact the electroplating solution on both sides of the electroplating tank. In addition, the setting of the lifting unit facilitates lifting the guide upwards after electroplating is completed, thereby facilitating the unloading operation of the guide after electroplating.

[0015] Further, the horizontal movement unit includes support plates connected to the outer walls on both sides of the electroplating tank, a ball screw horizontally rotatably connected to the two support plates together, the ball screw being driven to rotate by a servo motor installed on one of the support plates, a nut sleeve threadedly sleeved on the periphery of the ball screw, the nut sleeve and the ball screw constituting a rolling spiral drive, and a moving block fixedly sleeved on the nut sleeve.

[0016] Through the above technical solution, the output shaft of the servo motor rotates, thereby driving the ball screw to rotate. When the ball screw rotates, it drives the nut sleeve and the moving block to move, thereby realizing driving the moving block to move horizontally back and forth, and further driving the guide to move horizontally back and forth in the electroplating tank.

[0017] Further, the lifting unit includes a lifting cylinder vertically installed on the bottom surface of the moving block, and the cylinder rod of the lifting cylinder is connected to the lifting block.

[0018] Through the above technical solution, by enhancing the telescopic movement of the cylinder rod of the cylinder, the lifting block is driven to move vertically, so as to lift the guide, which facilitates the unloading of the guide.

[0019] Furthermore, a guide rod is commonly passed through the outer walls of the two support plates, and a guide hole for the free passage of the guide rod is provided on the outer wall of the moving block.

[0020] Through the above technical solution, when the ball screw and the nut sleeve perform rolling spiral transmission, the moving block will not deflect because the guide rod slides in the guide hole.

[0021] Furthermore, the clamping assembly includes a fixing part fixedly connected to one end of the support shaft away from the lifting block. A plurality of cylindrical protrusions are fixedly connected to the periphery of the fixing part. A pressing rod is coaxially passed through the cylindrical protrusion. The pressing rod slides freely on the cylindrical protrusion, and one end of the pressing rod passing through the cylindrical protrusion is fixedly connected with an arc-shaped clamping plate. The pressing rod is driven to slide on the cylindrical protrusion by a pressing unit arranged in the fixing part.

[0022] Through the above technical solution, the pressing unit drives the pressing rod to move towards the outer side of the cylindrical protrusion, and then the pressing rod synchronously drives the arc-shaped clamping plate to move, so that the arc-shaped clamping plate can clamp the inner ring of the guide, which is convenient for quickly clamping the guide.

[0023] Furthermore, the pressing unit includes a stop ring fixedly sleeved on the periphery of the pressing rod. A sliding cavity for the free passage of the stop ring is provided in the cylindrical protrusion. A first spring is wound around the periphery of the pressing rod. The two ends of the elastic force direction of the first spring are respectively elastically abutted against the stop ring and the inner wall of the sliding cavity. A pressing bolt is threadedly passed through the end of the support shaft. A frustum-shaped part is fixedly sleeved on the periphery of the pressing bolt. The outer diameter of the frustum-shaped part increases in turn towards the direction away from the support shaft. A ball is rotatably embedded at one end of the pressing rod facing the frustum-shaped part, and the ball rolls and contacts the periphery of the frustum-shaped part.

[0024] Through the above technical solution, when clamping the inner ring of the guide, by screwing the pressing bolt on the support shaft, the frustum-shaped part is driven to move towards the support shaft, and the ball rolls on the frustum-shaped part from the end with the smaller outer diameter of the frustum-shaped part to the end with the larger outer diameter of the frustum-shaped part, so as to drive the pressing rod to move towards the outer side of the cylindrical protrusion. The pressing rod synchronously drives the arc-shaped clamping plate to move towards the outer side of the cylindrical protrusion, so that the arc-shaped clamping plate presses against the inner ring of the guide, thus completing the fixation of the guide.

[0025] Further, the flushing assembly includes a flushing plate sleeved on the support shaft. The flushing plate is key-connected to the support shaft and freely slides on the periphery of the support shaft. A fixing ring is fixedly connected to one side of the lifting block facing the flushing plate. An installation column is fixedly connected to one end face of the fixing ring facing the flushing plate. A roller is rotatably connected to the end of the installation column away from the fixing ring. A follower ring is fixedly connected to the end face of the flushing plate. An arc-shaped protrusion is fixedly connected to the end face of the follower ring. When the support shaft rotates, the roller alternately rolls in contact with the arc-shaped protrusion and the end face of the follower ring. A limiting ring is fixedly sleeved on the periphery of the support shaft, and the limiting ring is located between the fixing part and the flushing plate. A second spring is also wound around the support shaft, and the two ends of the second spring in the elastic force direction respectively elastically abut against the limiting ring and the flushing plate.

[0026] Through the above technical solution, when the support shaft rotates, the roller will alternately roll on the arc-shaped protrusion and the end face of the follower ring. When the roller rolls from the end face of the follower ring to the surface of the arc-shaped protrusion, the roller will drive the flushing plate to move towards the direction of the guide, so that the flushing plate can stir the electroplating solution in the electroplating tank. And through the elastic abutment of the second spring against the flushing plate, the flushing plate can reciprocate. When the flushing plate reciprocates on the support shaft, the electroplating solution in the electroplating tank can be stirred towards the direction of the blades of the guide, and the electroplating solution can be formed into a flowing state in the electroplating tank. Compared with the prior art in which the electroplating solution is stationary, it can make the electroplating solution flow through the surface of the blades of the guide, increase the contact range between the platinum ions in the electroplating solution and the blades, and improve the electroplating effect.

[0027] Further, a gear is fixedly sleeved on the end of the support shaft away from the fixing part. A rack is horizontally and fixedly connected to the inner wall of the electroplating tank. The gear is in a meshing state with the rack.

[0028] Through the above technical solution, when the lifting block reciprocates horizontally in the electroplating tank, it will cause the gear to mesh and rotate with the rack, and then drive the gear to rotate. When the gear rotates, it synchronously drives the support shaft to rotate, and the structure is simple.

[0029] Further, a plurality of through grooves are formed in the end face of the flushing plate. A limiting column is fixedly connected in the through groove. The axial direction of the limiting column is orthogonal to the axial direction of the support shaft. A sliding block is snap-fitted in the through groove. A through hole for the limiting column to slide and insert is formed in the sliding block. A plurality of thin rods are fixedly connected to the side of the sliding block facing the flushing plate. A rotating ring is coaxially and rotatably sleeved on the periphery of the fixing ring. A plurality of hinge rods are hinged to the periphery of the rotating ring. The end of the hinge rod away from the rotating ring is correspondingly hinged to the outer wall of the sliding block.

[0030] Through the above technical solution, the sliding block reciprocates radially along the scouring plate in the through groove, enabling the thin rod to defoam the air bubbles in the electroplating solution. Then, when the scouring plate deflects the electroplating solution towards the direction of the guide, the generated bubbles can be punctured by the thin rod, reducing the adhesion of bubbles on the guide blades and avoiding the influence of bubbles on the electroplating effect. In addition, when the scouring plate reciprocates on the support shaft, the hinge rod will drive the sliding block to reciprocate in the through groove, enabling the thin rod to reciprocate radially along the support shaft. Coupled with the rotation of the support shaft, the defoaming range of the thin rod for air bubbles is greatly increased, improving the defoaming efficiency for air bubbles.

[0031] The beneficial effects of the present invention are as follows:

[0032] (1) In the present invention, the inner ring of the guide is clamped and fixed by the clamping assembly, and then the clamping assembly is driven by the suspension assembly to move horizontally in the electroplating tank, enabling the blades on the guide to fully contact the electroplating solution. In addition, during the horizontal reciprocating movement of the guide in the electroplating tank, the scouring assembly repeatedly deflects the electroplating solution towards the blades of the guide, enabling the electroplating solution to flow and contact the surfaces of various parts of the guide blades, thereby improving the electroplating effect of the guide blades to a certain extent;

[0033] (2) In the present invention, the tightening bolt is screwed on the support shaft, thereby driving the frustum part to move towards the support shaft, and enabling the ball to roll from the smaller diameter end of the frustum part to the larger diameter end of the frustum part, thereby driving the tightening rod to move towards the outside of the protruding part. The tightening rod synchronously drives the arc-shaped clamping plate to move towards the outside of the protruding part, thereby enabling the arc-shaped clamping plate to tightly hold the inner ring of the guide, thus completing the fixation of the guide and facilitating the quick clamping of the guide for electroplating;

[0034] (3) In the present invention, the sliding block reciprocates radially along the scouring plate in the through groove, enabling the thin rod to defoam the air bubbles in the electroplating solution. Then, when the scouring plate deflects the electroplating solution towards the direction of the guide, the generated bubbles can be punctured by the thin rod, reducing the adhesion of bubbles on the guide blades and avoiding the influence of bubbles on the electroplating effect. In addition, when the scouring plate reciprocates on the support shaft, the hinge rod will drive the sliding block to reciprocate in the through groove, enabling the thin rod to reciprocate radially along the support shaft. Coupled with the rotation of the support shaft, the defoaming range of the thin rod for air bubbles is greatly increased, improving the defoaming efficiency for air bubbles.

Detailed implementation manners

[0046] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] As Figures 1-10 shown, this embodiment provides a platinum plating device for double and multi-connected guide vane, including an electroplating tank 1 and electrodes 11 installed on both sides of the electroplating tank 1. The two electrodes 11 are respectively an anode and a cathode, and the two electrodes 11 are in a circuit path;

[0048] Combined with Figure 1 and Figure 2 shown, the outer walls on both sides in the length direction of the electroplating tank 1 are connected to the support plates 2 by screws. A ball screw 3 is horizontally rotatably connected between the two support plates 2. The ball screw 3 is driven to rotate by a servo motor 7 installed on one of the support plates 2. A nut sleeve 13 is threadedly sleeved on the periphery of the ball screw 3. The nut sleeve 13 and the ball screw 3 form a rolling spiral drive. A moving block 5 is fixedly sleeved on the nut sleeve 13. When the servo motor 7 is powered on, its output shaft rotates, and then drives the ball screw 3 to rotate. Since the nut sleeve 13 and the ball screw 3 are in rolling spiral drive, the nut sleeve 13 will move horizontally along the axial direction of the ball screw 3. When the nut sleeve 13 moves horizontally, it will synchronously drive the moving block 5 to move. In addition, a guide rod 4 is commonly passed through the outer walls of the two support plates 2. A guide hole for the free passage of the guide rod 4 is opened on the outer wall of the moving block 5. The guide rod 4 slides in the guide hole, so that when the ball screw 3 and the nut sleeve 13 are in rolling spiral drive, the moving block 5 will not generate a phenomenon of deflecting around the axial direction of the ball screw 3;

[0049] Combined with Figure 1 and Figure 2 shown, a lifting cylinder 6 is vertically installed on the bottom surface of the moving block 5. The cylinder rod of the lifting cylinder 6 is connected to a lifting block 9. When the cylinder rod of the lifting cylinder 6 extends or shortens, it synchronously drives the lifting block 9 to move downwards and upwards. In addition, when the ball screw 3 rotates, the moving block 5 will move horizontally and synchronously drive the lifting block 9 to move horizontally in the electroplating tank 1;

[0050] Combined with Figures 3 to 10 shown, a support shaft 25 is horizontally passed through the lifting block 9. The support shaft 25 is rotatably connected to the lifting block 9 by installing a plurality of ball bearings. Thus, the support shaft 25 will freely rotate on the lifting block 9. A fixing part 21 is provided at one end of the support shaft 25 away from the lifting block 9. A plurality of cylindrical protrusions (18) are fixedly connected to the periphery of the fixing part 21. A pressing rod 32 is coaxially passed through the cylindrical protrusion (18). The pressing rod 32 freely slides on the cylindrical protrusion (18) and the end thereof passing through the cylindrical protrusion (18) is fixedly connected to an arc-shaped clamping plate 20. When the pressing rod 32 moves towards the outside of the cylindrical protrusion (18), the pressing rod 32 synchronously drives the arc-shaped clamping plate 20 to move. In this way, the arc-shaped clamping plate 20 can clamp the inner ring of the guide vane, which is convenient for quickly clamping the guide vane.

[0051] Combined withFigures 3 to 10 As shown, a stop ring 34 is fixedly sleeved on the periphery of the pressing rod 32. A sliding cavity for the free passage of the stop ring 34 is provided in the cylindrical protrusion (18), that is, the stop ring 34 can freely slide along the axial direction of the cylindrical protrusion (18) in the sliding cavity. In addition, the outer diameter of the stop ring 34 can be set to be the same as the inner diameter of the sliding cavity. A first spring 35 is wound around the periphery of the pressing rod 32. The two ends of the first spring 35 in the direction of the elastic force elastically abut against the stop ring 34 and the inner wall of the sliding cavity respectively. A pressing bolt 19 is threadedly penetrated through the end of the support shaft 25. A frustum 31 is fixedly sleeved on the periphery of the pressing bolt 19. The outer diameter of the frustum 31 increases sequentially in the direction away from the support shaft 25. A ball 33 is rotatably installed at one end of the pressing rod 32 facing the frustum 31. The ball 33 rolls and contacts the periphery of the frustum 31. In the initial stage, when fixing the guide to facilitate the electroplating operation, first use an external tool (such as an inner hexagon wrench, etc.) to rotate the pressing bolt 19, so that the pressing bolt 19 is threadedly engaged on the support shaft 25, and then drive the frustum 31 to move towards the support shaft 25, and make the ball 33 roll from the smaller-diameter end of the frustum 31 to the larger-diameter end of the frustum 31 on the frustum 31, and then drive the pressing rod 32 to move towards the outside of the cylindrical protrusion (18). The pressing rod 32 synchronously drives the arc-shaped clamping plate 20 to move towards the outside of the cylindrical protrusion (18), so that the arc-shaped clamping plate 20 abuts against the inner ring of the guide, thereby completing the fixation of the guide.

[0052] Combined with Figures 3 to 7As shown, a disc-shaped scouring plate 10 is sleeved on the periphery of the support shaft 25. The scouring plate 10 is key-connected to the support shaft 25 and can slide freely on the periphery of the support shaft 25, so that the scouring plate 10 and the support shaft 25 can rotate synchronously. A fixing ring 28 is fixedly connected to one side of the lifting block 9 facing the scouring plate 10. Two mounting posts 29 are fixedly connected to the end face of the fixing ring 28 on the side facing the scouring plate 10. The two mounting posts 29 are arranged in an axial array of the support shaft 25 on the end face of the fixing ring 28. A roller 30 is rotatably connected to the end of the mounting post 29 away from the fixing ring 28. A follower ring 15 is fixedly connected to the end face of the scouring plate 10. An arc-shaped protrusion 27 is fixedly connected to the end face of the follower ring 15. The intersection of the arc-shaped protrusion 27 and the end face of the follower ring 15 is in a smooth transition. When the support shaft 25 rotates, the roller 30 alternately rolls on the arc-shaped protrusion 27 and the end face of the follower ring 15. A limiting ring 22 is fixedly sleeved on the periphery of the support shaft 25. The limiting ring 22 is located between the fixing part 21 and the scouring plate 10. A second spring 23 is also wound around the support shaft 25. The two ends of the second spring 23 in the direction of the elastic force elastically abut against the limiting ring 22 and the scouring plate 10 respectively. A gear 8 is fixedly sleeved on the end of the support shaft 25 away from the fixing part 21. A rack 12 is horizontally and fixedly connected to the inner wall of the electroplating tank 1. The gear 8 is in a meshing state with the rack 12. When the lifting block 9 reciprocates horizontally in the electroplating tank 1, the gear 8 and the rack 12 will be engaged and rotated, and the support shaft 25 will be driven to rotate. When the support shaft 25 rotates, the scouring plate 10 will be driven to rotate synchronously. Since the fixing ring 28 is fixedly connected to the lifting block 9, at this time, the follower ring 15 will rotate relative to the fixing ring 28. With the elastic abutting force of the second spring 23 on the scouring plate 10, the roller 30 alternately rolls on the arc-shaped protrusion 27 and the end face of the follower ring 15. Specifically, when the roller 30 rolls from the end face of the follower ring 15 to the surface of the arc-shaped protrusion 27, at this time, the follower ring 15 will move away from the fixing ring 28 on the support shaft 25, thereby driving the scouring plate 10 to move towards the direction of the guide on the support shaft 25. At the same time, the scouring plate 10 starts to compress the second spring 23, and the second spring 23 stores elastic potential energy. When the roller 30 rolls from the surface of the arc-shaped protrusion 27 to the end face of the follower ring 15, the elastic potential energy stored in the second spring 23 is released, and then the scouring plate 10 will be driven to move towards the direction of the fixing ring 28. Repeating like this, the scouring plate 10 reciprocates horizontally on the support shaft 25. When the scouring plate 10 reciprocates horizontally in the electroplating tank 1, it will be able to stir the electroplating solution in the electroplating tank 1, making the electroplating solution on both sides of the guide blades in a flowing state to increase the contact between the electroplating solution and the guide blades.

[0053] Combined Figures 3 to 7As shown, a plurality of through grooves 24 are formed in the end face of the flushing plate 10. The length direction of the through grooves 24 is orthogonal to the axial direction of the support shaft 25. A limiting column 37 is fixedly connected in the through groove 24, and the axial direction of the limiting column 37 is orthogonal to the axial direction of the support shaft 25. A sliding block 17 is snap-fitted and installed in the through groove 24. A through hole for the limiting column 37 to slide and insert is formed in the sliding block 17. When the sliding block 17 slides on the limiting column 37, it is limited by the inner side wall of the through groove 24, so that the sliding block 17 will not swing. In addition, a plurality of thin rods 16 are fixedly connected to the surface of the sliding block 17 facing the flushing plate 10 in a uniformly distributed manner. A rotating ring 14 is coaxially rotatably sleeved on the periphery of the fixed ring 28. Specifically, two annular flanges 36 are coaxially fixedly connected to the periphery of the fixed ring 28. The rotating ring 14 is located between the two annular flanges 36. The annular flanges 36 limit the rotating ring 14, so that the rotating ring 14 is rotatably connected to the periphery of the fixed ring 28. A plurality of hinge rods 26 are hinged to the periphery of the rotating ring 14. The end of the hinge rod 26 away from the rotating ring 14 is correspondingly hinged to the outer wall of the sliding block 17. The hinge rod 26, the rotating ring 14 and the sliding block 17 form a crank-slider mechanism. That is, when the flushing plate 10 moves horizontally back and forth, the sliding block 17 is synchronously driven to move horizontally. Due to the action of the hinge rod 26, the sliding block 17 will move in the through groove 24, so that the sliding block 17 moves along the radial direction of the support shaft 25. Thus, the thin rods 16 can defoam the bubbles generated when the flushing plate 10 stirs the electroplating solution.

[0054] The working principle of this embodiment is as follows:

[0055] Clamping guide: The cylinder rod of the lifting cylinder 6 shortens, driving the lifting block 9, the fixing part 21 and the arc-shaped clamping plate 20 to move upward synchronously. When the arc-shaped clamping plate 20 moves upward to the fixed position, the staff puts the inner ring of the guide on multiple arc-shaped clamping plates 20, and then uses an external tool (such as an Allen wrench, etc.) to rotate and tighten the bolt 19, so that the tightening bolt 19 is threadedly engaged on the support shaft 25, thereby driving the frustum part 31 to move in the direction of the support shaft 25, and making the ball 33 roll from the smaller outer diameter end of the frustum part 31 to the larger outer diameter end of the frustum part 31 on the frustum part 31, thereby driving the tightening rod 32 to move in the outer direction of the cylindrical protrusion (18), and the tightening rod 32 drives the arc-shaped clamping plate 20 to move in the outer direction of the cylindrical protrusion (18) synchronously, so that the arc-shaped clamping plate 20 clamps the inner ring of the guide, thus completing the fixation of the guide. Then start the lifting cylinder 6 again. The cylinder rod of the lifting cylinder 6 elongates, driving the lifting block 9 to move downward into the electroplating tank 1 until the gear 8 meshes with the rack 12. If the gear 8 and the rack 12 are not correctly meshed, the lifting cylinder 6 can be started again. The cylinder rod of the lifting cylinder 6 shortens, driving the gear 8 to move upward, and then the staff manually rotates the guide, and then starts the lifting cylinder 6 again. The cylinder rod of the lifting cylinder 6 shortens and drives the gear 8 to move downward again so that the gear 8 can mesh with the rack 12. At this time, the guide is submerged in the electroplating solution in the electroplating tank 1;

[0056] Electroplating operation: Connect the power supply of the electroplating equipment to energize the electrode 11, so that the electrode 11 can start the electroplating operation. The platinum ions in the electroplating bath 1 enter the electroplating solution and form a directional flow. During the electroplating process, connect the external power supply to energize the servo motor 7. When the servo motor 7 is energized, its output shaft rotates, which will drive the ball screw 3 to rotate. Since the nut sleeve 13 and the ball screw 3 are in a rolling screw drive, the nut sleeve 13 will move horizontally along the axial direction of the ball screw 3. When the nut sleeve 13 moves horizontally, it will drive the moving block 5 to move synchronously. In addition, use an external controller, such as a PLC module, to control the rotation direction of the servo motor 7, so that the moving block 5 can move horizontally back and forth, thereby driving the guide in the electroplating bath 1 to move horizontally back and forth. When the lifting block 9 moves horizontally back and forth in the electroplating bath 1, it will cause the gear 8 and the rack 12 to mesh and rotate, and drive the support shaft 25 to rotate. When the support shaft 25 rotates, it will drive the scouring plate 10 to rotate synchronously. Since the fixed ring 28 is fixedly connected to the lifting block 9, at this time, the follower ring 15 will rotate relative to the fixed ring 28. With the elastic abutting force of the second spring 23 on the scouring plate 10, the rollers 30 alternately roll on the arc-shaped protrusion 27 and the end surface of the follower ring 15. Specifically, when the roller 30 rolls from the end surface of the follower ring 15 to the surface of the arc-shaped protrusion 27, at this time, the follower ring 15 will move away from the fixed ring 28 on the support shaft 25, thereby driving the scouring plate 10 to move towards the guide on the support shaft 25. At the same time, the scouring plate 10 starts to compress the second spring 23, and the second spring 23 stores elastic potential energy. When the roller 30 rolls from the surface of the arc-shaped protrusion 27 to the end surface of the follower ring 15, the elastic potential energy stored in the second spring 23 is released, which will drive the scouring plate 10 to move towards the fixed ring 28. Repeating like this, the scouring plate 10 moves horizontally back and forth on the support shaft 25. When the scouring plate 10 moves horizontally back and forth in the electroplating bath 1, it will be able to stir the electroplating solution in the electroplating bath 1, making the electroplating solution on both sides of the guide blade flow, so as to increase the contact between the electroplating solution and the guide blade. When the scouring plate 10 moves horizontally back and forth, it will drive the sliding block 17 to move horizontally synchronously. Due to the action of the hinge rod 26, the sliding block 17 will move in the through groove 24, so that the sliding block 17 moves along the radial direction of the support shaft 25, thereby enabling the thin rod 16 to defoam the bubbles generated when the scouring plate 10 stirs the electroplating solution;

[0057] Operation completed: After the operation is completed, the lifting cylinder 6 is started. The cylinder rod of the lifting cylinder 6 shortens and drives the guide to move upward, so that the guide is disengaged from the contact with the electroplating solution. Then, the worker uses the tool to rotate the tightening bolt 19 in the reverse direction again, so that the tightening bolt 19 drives the frustum portion 31 to move in the reverse direction, thereby releasing the elastic potential energy of the first spring 35 and driving the tightening rod 32 and the arc-shaped clamping plate 20 to move towards the radially inner side of the support shaft 25. As a result, the arc-shaped clamping plate 20 can be disengaged from the inner ring of the guide. Then, the worker removes the guide from the arc-shaped clamping plate 20, completing one electroplating operation.

[0058] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
