Abstract

This utility model relates to the technical field of titanium alloy integral bladed disk electroplating device, and more particularly to a comprehensive protective electroplating device for titanium alloy integral bladed disks. It includes: an electroplating tank, a lifting assembly on one side of the electroplating tank, a self-rotation and revolution integrated assembly on the lifting assembly, and several inner pressing components at the bottom of the self-rotation and revolution integrated assembly. By setting up the lifting assembly, a motor drives a lead screw to rotate, converting the rotational motion into the linear motion of a drive block, thereby driving the top cover to rise and fall smoothly, ensuring a tight fit between the top cover and the electroplating tank when closed, effectively preventing the electroplating solution from overflowing and external impurities from entering. By setting up the self-rotation and revolution integrated assembly, the rotational power of a second motor is converted into the compound motion of planetary gears, and precisely transmitted to the inner pressing components through a second rotating shaft, allowing the bladed disk to smoothly perform a compound motion of self-rotation and revolution, ensuring that all parts of the bladed disk in the electroplating solution can make uniform and sufficient contact with the electroplating solution.

Description

Technical Field

[0001] This utility model relates to the technical field of electroplating devices for integral titanium alloy bladed disks, and in particular to an electroplating device for comprehensive protection of integral titanium alloy bladed disks. Background Technology

[0002] A titanium alloy integral bladed disk is a type of integral blade structure made of titanium alloy. Titanium alloy is a metallic material with high strength, low density, and excellent corrosion resistance. It is commonly used in aerospace, automotive, and medical device fields. Titanium alloy integral bladed disks require electroplating during the manufacturing process.

[0003] However, in actual processing, titanium alloy integral impellers lack effective protective design. When the impeller moves with the cathode mechanism, the electroplating solution is prone to splashing outward due to mechanical vibration or centrifugal force. This not only shortens the overall service life of the equipment but also causes external injury to the human body. Secondly, the cathode moving mechanism of traditional devices often adopts a single-axis mechanical swing structure. The impeller is prone to swaying and shaking in non-uniform reciprocating motion, resulting in insufficient contact between the electroplating solution and the impeller surface and disordered dynamic interaction, which in turn reduces the electroplating quality. Utility Model Content

[0004] The purpose of this invention is to provide a comprehensive protective electroplating device for titanium alloy integral bladed disks, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: it includes an electroplating tank, a lifting assembly is provided on one side of the electroplating tank, a self-rotation and revolution integrated assembly is provided on the lifting assembly, and several inner pressing assemblies are provided at the bottom of the self-rotation and revolution integrated assembly.

[0006] As a preferred embodiment of the present invention, the lifting assembly includes a mounting frame 1 disposed on one side of the electroplating tank, a fixing sleeve disposed on the bottom surface of the mounting frame 1, a lead screw inserted into the fixing sleeve, and a motor 1 disposed on the inner top surface of the mounting frame 1, with one end of the lead screw connected to one end of the motor 1.

[0007] As a preferred embodiment of this utility model, a driving block is provided on the outer spiral sleeve of the lead screw, a pair of guide posts are symmetrically arranged on the mounting brackets on both sides of the lead screw, a guide sleeve is provided on the driving block at the position corresponding to the guide post, and a top cover corresponding to the electroplating tank is provided on one side of the driving block.

[0008] As a preferred embodiment of this utility model, the self-rotation and revolution integrated component includes a mounting box disposed on the top cover, a second motor disposed on the top of the mounting box, a first rotating shaft disposed on the transmission end of the second motor, the first rotating shaft passing through the mounting box, a sun gear sleeved on the outer side of the first rotating shaft, a gear ring disposed on the inner wall of the mounting box, and several planetary gears meshing between the sun gear and the gear ring.

[0009] As a preferred embodiment of this utility model, a circular plate is provided at the bottom of the first rotating shaft, an annular plate is provided at the bottom of the mounting box, and a second rotating shaft is provided inside each of the planetary gears, and the second rotating shafts move along the annular track formed between the circular plate and the annular plate.

[0010] As a preferred embodiment of this utility model, the inner pressing assembly includes a mounting bracket 2 disposed at the bottom of the rotating shaft 2. Several oil storage cylinders are disposed on the outer side of the bottom of the mounting bracket 2. A piston 1 is slidably disposed in each oil storage cylinder. A piston rod is disposed on one side of each piston 1. A support block is disposed at the end of each piston rod away from the oil storage cylinder. A spring is disposed between the support block and the oil storage cylinder.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0012] This invention features a lifting assembly. A motor drives a lead screw to rotate, precisely converting the rotational motion into linear motion of the drive block, thereby smoothly raising and lowering the top cover. Simultaneously, the combination of guide posts and guide sleeves provides guidance for the lifting and lowering of the top cover, effectively preventing deviation and wobbling. This ensures a tight fit between the top cover and the electroplating tank when closed, effectively preventing electroplating solution overflow and external impurities from entering. Operators only need to simply operate motor one to easily open and close the electroplating tank, improving operational efficiency.

[0013] This invention achieves a combined rotation and revolution motion of the impeller during the electroplating process by incorporating an integrated rotation and revolution component. The combination of the rotating shaft, sun gear, planetary gears, and gear ring efficiently and stably converts the rotational power of the motor into the combined motion of the planetary gears, which is then precisely transmitted to the inner clamping component via the rotating shaft. This allows the impeller to smoothly perform the combined rotation and revolution motion, ensuring that all parts of the impeller in the electroplating solution make uniform and sufficient contact with the solution. This greatly improves the uniformity of the electroplated layer deposition, effectively avoids electroplating defects caused by poor local contact, and significantly improves the electroplating quality.

[0014] This invention, by setting an inner pressing component, allows the clamping block to self-adjust under the elastic support of a spring, enabling it to closely fit the inner wall of impellers with different inner diameters. Secondly, the combined use of the oil reservoir, piston one, and piston rod, during the adjustment of the clamping block, allows hydraulic oil to flow through the small hole, generating damping force, which buffers and stabilizes the movement of the clamping block, preventing the clamping block from being suddenly subjected to force due to the rapid rebound of the spring, thus avoiding damage to the inner wall of the impeller and ensuring the safety of the impeller. It also ensures that the clamping force is evenly distributed, effectively preventing the impeller from shaking or shifting during the electroplating process. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] like Figures 1-5 As shown, the present invention proposes a titanium alloy integral bladed disk comprehensive protection electroplating device, which includes an electroplating tank 1, a lifting component 2 on one side of the electroplating tank 1, a self-rotation and revolution integrated component 3 on the lifting component 2, and several inner pressing components 4 at the bottom of the self-rotation and revolution integrated component 3.

[0023] The lifting assembly 2 includes a mounting frame 21 disposed on one side of the electroplating tank 1. The mounting frame 21 provides a mounting base for other components in the lifting assembly 2. A fixing sleeve 22 is disposed on the bottom surface of the mounting frame 21. A lead screw 23 is inserted into the fixing sleeve 22. The fixing sleeve 22 provides support for the lead screw 23 to ensure the stability of the lead screw 23 when rotating. A motor 24 is disposed on the top surface of the mounting frame 21. One end of the lead screw 23 is connected to one end of the motor 24. The motor 24 provides rotational power for the lead screw 23 and converts the rotational motion of the lead screw 23 into the linear motion of the drive block 25.

[0024] A drive block 25 is provided on the outer spiral sleeve of the lead screw 23. The drive block 25 provides the mounting base for the top cover 28. A pair of guide posts 26 are symmetrically arranged on the mounting brackets 21 on both sides of the lead screw 23. Guide sleeves 27 are provided on the drive block 25 at the positions corresponding to the guide posts 26. The cooperation between the guide sleeves 27 and the guide posts 26 can ensure the stability of the drive block 25 and the top cover 28 when they are raised and lowered. A top cover 28 corresponding to the electroplating tank 1 is provided on one side of the drive block 25. The top cover 28 is used to close or open the electroplating tank 1 to prevent the electroplating solution from splashing out during the electroplating process and to maintain the relative stability of the environment inside the electroplating tank 1.

[0025] The self-rotation and revolution integrated assembly 3 includes a mounting box 31 mounted on the top cover 28. The mounting box 31 provides a mounting base for other components in the self-rotation and revolution integrated assembly 3. A second motor 32 is mounted on the top of the mounting box 31. A first rotating shaft 33 is mounted on the transmission end of the second motor 32. The first rotating shaft 33 passes through the mounting box 31. The second motor 32 provides rotational power to the first rotating shaft 33. A sun gear 34 is mounted on the outer side of the first rotating shaft 33. The first rotating shaft 33 transmits the rotational power of the second motor 32 to the sun gear 34, driving the sun gear 34 to rotate. A gear ring 35 is mounted on the inner wall of the mounting box 31. Several planetary gears 36 mesh between the sun gear 34 and the gear ring 35. The planetary gears 36 revolve around the sun gear 34 while also rotating on their own axis, transmitting the combined motion to the second rotating shaft 37 and the inner pressing assembly 4.

[0026] A circular plate 38 is provided at the bottom of the first rotating shaft 33, and an annular plate 39 is provided at the bottom of the mounting box 31. Several planetary gears 36 are equipped with second rotating shafts 37. Several second rotating shafts 37 move along the annular track formed between the circular plate 38 and the annular plate 39 to ensure the stability of the second rotating shafts 37 when they move.

[0027] The inner clamping assembly 4 includes a mounting bracket 41 located at the bottom of the rotating shaft 37. The mounting bracket 41 provides a mounting base for other components in the inner clamping assembly 4. Several oil reservoirs 42 are located on the outer side of the bottom of the mounting bracket 41. The oil reservoirs 42 are used to store hydraulic oil. A piston 43 is slidably installed in each oil reservoir 42. The piston 43 divides the space inside the oil reservoir 42 into two chambers and moves with the piston rod 44. A piston rod 44 is provided on one side of each piston 43. The piston rod 44 pushes the piston 43 to move inside the oil reservoir 42 as the support block 45 moves. A support block 45 is provided at the end of each piston rod 44 away from the oil reservoir 42. The support block 45 is used to support the inner wall of the impeller to achieve stable fixation of the impeller. A spring 46 is provided between the support block 45 and the oil reservoir 42. The spring 46 provides elastic support for the support block 45 and allows the support block 45 to self-adjust according to the inner wall of the impeller.

[0028] In operation, the operator first injects an appropriate amount of electroplating solution into the electroplating tank 1, then starts the motor 24. The motor 24 drives the lead screw 23 to rotate, converting the rotational motion of the lead screw 23 into the linear motion of the drive block 25. The drive block 25 moves upward along the guide post 26, thereby causing the top cover 28, the self-rotation and revolution integrated assembly 3, and the inner pressing assembly 4 to rise together, thus opening the electroplating tank 1. Next, the operator aligns the impeller with the inner pressing assembly 4 and places it in place. The extensibility of the spring 46 allows the support block 45 to adaptively adjust according to the inner wall of the impeller. During the adjustment process, the support block 45... The clamping block 45 pushes the piston rod 44 and piston 43 to move inside the oil reservoir 42. Piston 43 divides the space inside the oil reservoir 42 into two chambers. The hydraulic oil in the oil reservoir 42 will flow repeatedly from one chamber to another through different small holes on piston 43. During the flow of hydraulic oil, the friction between the hole wall and the hydraulic oil and the internal friction between hydraulic oil molecules will hinder the flow of hydraulic oil, thereby generating a damping force to ensure that the clamping block 45 is stably attached to the inner wall of the impeller, thereby realizing the stable fixing of the impeller to the bottom of the self-rotation and revolution integrated assembly 3 by the inner pressing component 4.

[0029] Then, the operator can start motor 24 to lower the top cover 28 to completely seal the electroplating tank 1, preventing the electroplating solution from splashing out during the electroplating process and maintaining the relative stability of the environment inside the electroplating tank 1. Next, start motor 32, which drives shaft 33 to rotate. Shaft 33 drives the sun gear 34 to rotate, and the sun gear 34 meshes with the planetary gear 36. The planetary gear 36 meshes with the gear ring 35 on the inner wall of the mounting box 31, thereby driving the planetary gear 36 to revolve around the sun gear 34. At the same time, the planetary gear 36 also rotates on its own axis. The planetary gear 36 transmits this combined motion through shaft 37. The inner clamping component 4 is applied to cause the impeller to rotate and revolve simultaneously. The electroplating solution in the electroplating tank 1 undergoes an electrochemical reaction with the surface of the impeller. Metal ions gain electrons on the surface of the impeller and undergo a reduction reaction, gradually depositing to form an electroplating layer. As the impeller continuously rotates and revolves, all parts of it can be evenly contacted with the electroplating solution, thereby ensuring that the electroplating layer is evenly deposited on the surface of the impeller and improving the electroplating quality. When the electroplating time reaches the process requirements, motor 22 is turned off, and motor 124 is started to raise the top cover 28, opening the electroplating tank 1. The operator can then remove the electroplated titanium alloy impeller, completing the entire electroplating process.
