Description

Technical Field

[0001] This application relates to the field of shock absorber piston rod technology, specifically a CDC shock absorber piston rod shielding plating solution current device. Background Technology

[0002] The piston rod of a CDC shock absorber typically requires hard chrome plating in its specific working areas (such as the portion in contact with the seal) to provide extremely high hardness, wear resistance, and corrosion resistance. However, other parts of the piston rod (such as the ends that need to be welded or certain assembly areas) cannot be plated, as plating would affect weld quality or assembly accuracy.

[0003] Existing hard chrome plating methods for piston rods mostly involve fixing the piston rod body with a fixture and then completing the process through electroplating. However, this method is inconvenient because it makes it difficult to adjust the electroplating process by moving different parts of the piston rod according to usage requirements, resulting in inconvenience in use.

[0004] Therefore, this application provides a CDC shock absorber piston rod shielding plating solution current device to solve the above problems. Utility Model Content

[0005] This application provides a current shielding device for the piston rod of a CDC shock absorber, which aims to solve the problem mentioned in the background art that the existing piston rod hard chrome plating mostly uses a clamp to fix the piston rod body and then completes the processing through the electroplating operation, which is inconvenient to move and adjust the electroplating operation of different parts of the piston rod according to the usage requirements, and is therefore inconvenient to use.

[0006] To achieve the above objectives, this application provides the following technical solution: a CDC shock absorber piston rod shielding plating solution current device, including an operating platform, a control switch is provided on one side of the operating platform, and an electroplating mechanism is provided on the top of the operating platform;

[0007] To address the inconvenience of existing piston rod hard chrome plating methods, which typically involve fixing the piston rod body with a clamp before electroplating, making it difficult to adjust the piston rod to different parts according to usage requirements, the proposed electroplating mechanism includes sliding grooves on both sides of an operating platform. A guide rod is fixedly connected inside the sliding groove, and a slider is mounted outside the guide rod. A linear motor is fixedly connected to one side of the slider, and a protective shell is fixedly connected to one side of the slider. A connecting block is fixedly connected to the top of the protective shell, and an electric push rod is fixedly connected to one side of the connecting block. A connecting shell is fixedly connected to the output end of the electric push rod. An electrode plate is located inside the connecting shell, and multiple sets of ejector pins are arranged on the sides of the electrode plate. An insulating block is fixedly connected to the side of the connecting shell, and shielding blocks are fixedly connected to both ends of the connecting shell. A sealing block is fixedly connected to the side of the shielding block. A linear motor drives the slider to slide outside the guide rod set inside the sliding groove. The protective shell set on the side of the slider drives the connecting block to move. The electric push rods set on the sides of the two sets of connecting blocks push the two sets of connecting shells to move in opposite directions. The connecting shell moves to the outside of the piston rod. The shielding operation is performed by the shielding blocks set on both sides of the connecting shell, and the sealing block set on the side of the shielding block seals the connection with the piston rod. The plating current operation is performed on the outside of the piston rod by the connecting shell and the top pin set inside the connecting shell. The piston rod can be moved to shield the plating current operation according to the usage requirements. The operation is simple and quick and easy to use.

[0008] Preferably, to solve the problem of convenient slider movement, the slider is slidably connected to the guide rod, the slider is electrically connected to the linear motor, and the linear motor is located inside the protective shell. The sliding of the slider and the guide rod can improve the stability of the slider movement, and the electrical connection between the slider and the linear motor can facilitate the movement of the slider and make it easy to use.

[0009] Preferably, in order to solve the problem of convenient electroplating, the two sets of connecting shells are symmetrically arranged, and the two sets of electrode plates inside the connecting shells are divided into cathode and anode. Multiple sets of ejector pins are arranged in a ring array on the side of the electrode plates. By setting the electrode plates and ejector pins, the piston rod can be conveniently operated with the plating solution current, which is convenient to use.

[0010] Preferably, to solve the problem of clamping and fixing the piston rod, the operating platform has operating slots on both sides. A bidirectional screw is rotatably connected inside the operating slot, and a servo motor is fixedly connected to the outside of the operating platform. The output end of the servo motor extends into the operating slot and is fixedly connected to the bidirectional screw. Two sets of moving blocks are provided outside the bidirectional screw, and a fixing clamp is fixedly connected to the top of the moving blocks. The servo motor drives the bidirectional screw to rotate inside the operating slot. The bidirectional screw is threadedly connected to the externally provided moving blocks, so that the moving blocks slide inside the operating slot under force. The moving blocks drive the top-provided fixing clamp to move in opposite directions. The two sets of fixing clamps clamp and fix both ends of the piston rod, thereby improving the stability of the piston rod during plating current operation. The operation is simple, quick, and convenient.

[0011] Preferably, in order to solve the problem of easy movement of the movable block, the bidirectional screw is threadedly connected to the movable block, and the movable block is symmetrically arranged inside the operating groove. The movable block is slidably connected to the operating groove. The threads at both ends of the bidirectional screw are in opposite directions. The threaded connection between the bidirectional screw and the movable block allows the movable block to move in opposite directions within the operating groove under force, which is convenient to use.

[0012] Preferably, to address the issue of conveniently fixing the piston rod with the fixing blocks, the two sets of fixing blocks are symmetrically arranged, and the inner diameter of the two sets of fixing blocks is adapted to the size of the shock absorber piston rod. By using the two sets of fixing blocks, the shock absorber piston rod can be easily clamped and fixed, making it convenient to use.

[0013] This electroplating mechanism uses a linear motor to drive a slider that slides outside a guide rod inside a sliding groove. A protective shell on the side of the slider moves a connecting block. Electric actuators on the sides of the two connecting blocks push the two connecting shells to move in opposite directions. Once the connecting shells are moved outside the piston rod, shielding is achieved by shielding blocks on both sides of the connecting shells. A sealing block on the side of the shielding block seals the connection point with the piston rod. The plating current is applied to the outside of the piston rod via the connecting shell and the top rod inside the connecting shell. This allows for easy movement of the piston rod to shield the plating current according to usage requirements. The operation is simple, quick, and convenient.

[0014] This electroplating mechanism uses a servo motor to drive a bidirectional screw to rotate inside the operating tank. The bidirectional screw is threadedly connected to an externally mounted moving block, which causes the moving block to slide inside the operating tank under force. The moving block drives the fixed clamping block mounted on the top to move in opposite directions. The two sets of fixed clamping blocks clamp and fix the piston rod at both ends, thereby improving the stability of the piston rod when the plating solution current is operated. The mechanism is simple, quick, and easy to use. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Example 1

[0023] This embodiment provides a device for shielding the plating solution current of a CDC shock absorber piston rod, such as... Figure 1-4 As shown, the CDC shock absorber piston rod shielding plating solution current device includes an operating platform 1, a control switch 2 is provided on one side of the operating platform 1, and an electroplating mechanism 3 is provided on the top of the operating platform 1.

[0024] The electroplating mechanism 3 allows for easy movement of the piston rod to shield the plating solution current according to usage requirements, making operation simple, quick, and convenient.

[0025] Specifically, the electroplating mechanism 3 includes sliding grooves 31 on both sides of the operating platform 1. A guide rod 32 is fixedly connected inside the sliding groove 31. A slider 33 is provided outside the guide rod 32. A linear motor 34 is fixedly connected to one side of the slider 33. A protective shell 35 is fixedly connected to one side of the slider 33. A connecting block 36 is fixedly connected to the top of the protective shell 35. An electric push rod 37 is fixedly connected to one side of the connecting block 36. A connecting shell 38 is fixedly connected to the output end of the electric push rod 37. An electrode plate 39 is provided inside the connecting shell 38. Multiple sets of ejector pins 40 are provided on the side of the electrode plate 39. Insulating blocks 41 are fixedly connected to both sides of the connecting shell 38. Shielding blocks 42 are fixedly connected to both ends of the connecting shell 38. A sealing block 43 is fixedly connected to the side of the shielding block 42.

[0026] In use, the linear motor 34 drives the slider 33 to slide outside the guide rod 32 set inside the sliding groove 31. The protective shell 35 set on the side of the slider 33 drives the connecting block 36 to move. The electric push rods 37 set on the sides of the two sets of connecting blocks 36 push the two sets of connecting shells 38 to move in opposite directions. The electric push rods 37 advance at a speed of 5mm / s. The connecting shells 38 move to the outside of the piston rod. The shielding operation is performed by the shielding blocks 42 set on both sides of the connecting shells 38. The sealing block 43 set on the side of the shielding block 42 seals the connection with the piston rod. The connecting shells 38 and the ejector pin 40 set inside the connecting shells 38 operate the plating current on the outside of the piston rod. The piston rod can be moved to shield the plating current operation according to the usage requirements. The operation is simple and quick and easy to use. The insulating block 41 is made of PTFE material with a dielectric strength ≥30MV / m and a parasitic current blocking capacity >99.9%.

[0027] The shielding block 42 is made of PTFE (Teflon), a hollow sleeve that is precisely machined or ground, with the inner hole precisely fitted to the section of the piston rod to be shielded (the gap is usually controlled within 0.02 to 0.05 mm), the inner hole taper ≤ 0.01 mm / 100 mm, and the surface roughness Ra ≤ 0.8 μm.

[0028] The sealing block 43 is made of fluororubber. It is resistant to chromic acid, high temperature (up to 200℃), and has good elasticity. Appropriate hardness (usually 70-90 Shore A) and compression ratio (15%~25%) must be selected. Double O-rings or O-rings are used to improve reliability. The O-ring hardness is 80+5 Shore A, the compression ratio is 18%, and it is resistant to chromic acid corrosion for >500h.

[0029] Electrode 39 must be located inside the area to be plated and as close to the center as possible to avoid edge effects. Based on the length of the area to be plated and the required current (current density is usually 30-60 A / dm²), calculate the required number and distribution density of contact points. Typically, there should be at least 1 to 2 high-quality contact points per centimeter of circumference. The contact method is achieved through multi-contact ejector pins 40. Multiple ejector pins 40 are evenly distributed on the circumference to provide low voltage drop, high reliability contact, compensate for dimensional tolerances and thermal deformation, and reduce contact point ablation marks. The ejector pins 40 are commonly made of beryllium copper alloy, and the contact pressure of the ejector pins 40 is 0.8 to 1.2 N / point.

[0030] Furthermore, the slider 33 is slidably connected to the guide rod 32, and the slider 33 is electrically connected to the linear motor 34, which is located inside the protective shell 35. The sliding of the slider 33 and the guide rod 32 can improve the stability of the slider 33's movement. The electrical connection between the slider 33 and the linear motor 34 facilitates the movement of the slider 33 and makes it easy to use.

[0031] Furthermore, the two sets of connecting shells 38 are symmetrically arranged, and the two sets of electrode plates 39 inside the connecting shells 38 are divided into cathode and anode. Multiple sets of ejector pins 40 are arranged in a ring array on the side of the electrode plates 39. By setting the electrode plates 39 and ejector pins 40, the piston rod can be easily operated with plating current, making it convenient to use.

[0032] Example 2

[0033] Unlike Embodiment 1, in order to solve the problem of clamping and fixing the piston rod, the operating platform 1 has operating slots 44 on both sides. A bidirectional screw 45 is rotatably connected inside the operating slot 44. A servo motor 46 is fixedly connected to the outside of the operating platform 1. The output end of the servo motor 46 extends into the inside of the operating slot 44 and is fixedly connected to the bidirectional screw 45. Two sets of moving blocks 47 are provided outside the bidirectional screw 45. A fixing clamp 48 is fixedly connected to the top of the moving block 47.

[0034] In use, the servo motor 46 drives the bidirectional screw 45 to rotate inside the operating groove 44. The bidirectional screw 45 is threadedly connected to the externally set moving block 47, so that the moving block 47 slides inside the operating groove 44 under force. The moving block 47 drives the fixed clamping block 48 set at the top to move in opposite directions. The two sets of fixed clamping blocks 48 clamp and fix the two ends of the piston rod, thereby improving the stability of the piston rod when the plating solution current is operated. The operation is simple and quick and convenient to use.

[0035] Specifically, the bidirectional screw 45 is threadedly connected to the movable block 47, and the movable block 47 is symmetrically arranged inside the operating groove 44. The movable block 47 is slidably connected to the operating groove 44. The threads at both ends of the bidirectional screw 45 are in opposite directions. The threaded connection between the bidirectional screw 45 and the movable block 47 allows the movable block 47 to move in opposite directions within the operating groove 44 under force, making it convenient to use. The bidirectional screw 45 is made of 40Cr alloy steel, heat-treated to HRC28-32, and has a 5μm hard chrome plating on the surface.

[0036] Furthermore, the two sets of fixing blocks 48 are symmetrically arranged, and the inner diameter of the two sets of fixing blocks 48 is adapted to the size of the shock absorber piston rod. The two sets of fixing blocks 48 can be used to easily clamp and fix the shock absorber piston rod, making it convenient to use. The fixing blocks 48 are made of high-hardness stainless steel (such as 440C) or ceramic, with surface hardening treatment (such as hard chrome plating or nitriding), which is wear-resistant and dimensionally stable. The inner diameter is precisely matched with the piston rod diameter (H6 / h5 grade tolerance), and the radial clamping force of the fixing blocks 48 is 200±10N.

[0037] It should be noted that the control switch 2, linear motor 34 and electric actuator 37 are existing devices, and their working principle, size and model are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0038] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
