Description

Technical Field

[0001] This application relates to the technical field of thrust bearing corner plate coating, and in particular to a thrust bearing corner plate and coating clamping fixture. Background Technology

[0002] PVD coating utilizes gas discharge to partially ionize the gas or evaporated material. Simultaneously, the evaporated material or its reactants are deposited onto the substrate under the bombardment of these ions. It features rapid deposition and a clean surface, and is particularly characterized by strong film adhesion, good diffraction properties, and a wide range of plating materials.

[0003] PVD nano-coating technology can improve the surface hardness of workpieces, providing features such as low friction, high temperature resistance, and corrosion resistance. Furthermore, the PVD process has no adverse environmental impact, aligning with the development trend of modern green manufacturing. It is now widely used in tooling, industrial components, automotive parts, and the medical industry. Applying PVD coatings to various workpieces such as cutting tools, molds, parts, and fasteners can significantly extend their service life and improve production efficiency.

[0004] Thrust bearings are specialized bearings designed to withstand axial forces, meaning forces acting in the direction parallel to the shaft. A thrust bearing typically consists of two or more thrust plates and several rolling elements. During operation, the thrust bearing plates bear loads and experience relative sliding, which causes wear on the plates. Once this wear reaches a certain level, it affects the bearing's service life.

[0005] Therefore, a surface treatment technology is needed to increase the service life of corner pieces. This application provides a PVD coating that has the effect of increasing friction and reducing wear, which can significantly improve the service life of corner pieces. However, in the coating process, the existing technology uses wire threading through the inner hole for clamping, which results in low clamping efficiency, unstable coating appearance, uneven coating thickness, and a small number of clamps. Utility Model Content

[0006] The purpose of this application is to provide a thrust bearing angular plate and coating clamping fixture to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this application provides a thrust bearing angular plate and coating clamping fixture using the following technical solution.

[0008] On the one hand, this application provides a thrust bearing angular plate, which adopts the following technical solution:

[0009] A thrust bearing angular plate includes an angular plate body, the angular plate body including an integrally formed circular block and a circular protrusion, the circular protrusion being concentrically arranged with the circular block, a through hole penetrating the circular block and the circular protrusion being formed in the middle of the angular plate body, and a DLC coating being applied to the surface of the angular plate body away from the circular protrusion.

[0010] By adopting the above technical solution, a DLC coating is applied to the corner piece body, specifically an aC:H:W coating with a thickness of 2-3μm and a hardness of 1200-2000HV. This coating increases wear resistance, reduces friction, and extends the service life of the corner piece.

[0011] On the other hand, this application also provides a coating clamping fixture for clamping the aforementioned thrust bearing angular plates, employing the following technical solution:

[0012] A coating clamping fixture for clamping the aforementioned thrust bearing corner piece includes a clamping frame and several hangers. The hangers can be suspended on the clamping frame. The cross-section of the clamping frame is a regular polyhedron. Rectangular hanging holes are provided on the side of the clamping frame. Clamping holes are provided on both the upper and lower end faces of the clamping frame. An upper hanging hole is provided on the top surface of the clamping frame corresponding to the position of the hanging holes.

[0013] The hanging bracket includes a main frame, an upper hook, a lower hook, and two movable fixing rods. The upper hook and the lower hook are respectively fixed to the main frame. A through slot is opened in the vertical direction of the main frame. The two movable fixing rods are symmetrically arranged in the through slot. Each movable fixing rod includes a rod body. Both ends of the rod body are threaded with fastening screws. The rod body is fixed to the main frame by fastening screws. Several magnets are uniformly fixed on the surface of the rod body.

[0014] Preferably, the clamping frame has a hollowed-out center that is connected to the hanging hole.

[0015] By adopting the above technical solution, the clamping frame is hollowed out in the middle, which on the one hand makes the coating tooling lighter and easier for clamping personnel to pick up and put down, and on the other hand helps to pick up and put down the corner piece hanger.

[0016] Preferably, the clamping frame is a regular dodecahedron, and the hanging brackets can be distributed in three equal parts or in four equal parts on the clamping frame.

[0017] By adopting the above technical solution, dividing the parts into three equal parts can achieve the clamping of corner pieces with a diameter of up to 110mm, and dividing them into four equal parts can achieve the clamping of corner pieces with a diameter of up to 85mm.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. By coating the surface of the thrust bearing angular plate with DLC coating, it has the advantages of increasing wear resistance, reducing friction, and extending the service life of the angular plate;

[0020] 2. By setting up clamping fixtures, and through the equal arrangement and the cooperation of movable fixing rods, corner pieces of different sizes and models can be clamped and used at the same time, reducing fixture costs, increasing furnace loading capacity, and ensuring that the coating area of ​​the corner pieces faces outwards, thus guaranteeing coating quality and coating thickness uniformity.

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This application discloses a thrust bearing angular plate, referring to... Figure 1 The corner piece body 1 includes an integrally formed circular block 11 and a circular protrusion 12. The circular protrusion 12 is concentrically arranged with the circular block 11. A through hole is provided in the middle of the corner piece body 1, which passes through the circular block 11 and the circular protrusion 12. The surface of the corner piece body 1 away from the circular protrusion 12 is coated with a DLC coating.

[0029] By coating the corner piece body 1 with a DLC coating, specifically an aC:H:W coating with a thickness of 2-3μm and a hardness of 1200-2000HV, the wear resistance is increased, friction is reduced, and the service life of the corner piece is extended.

[0030] This application also discloses a coating clamping fixture for clamping the aforementioned thrust bearing angular plates, referring to... Figure 2-3 The device includes a clamping frame 2 and several hanging brackets 3. The hanging brackets 3 can be suspended on the clamping frame 2. The cross-section of the clamping frame 2 is a regular polyhedron. The clamping frame 2 is a regular dodecahedron. Rectangular hanging holes 22 are provided on the side of the clamping frame 2. Clamping holes 23 are provided on the upper and lower end faces of the clamping frame 2. The top surface of the clamping frame 2 is provided with an upper hanging hole 21 corresponding to the position of the hanging hole 22. The middle part of the clamping frame 2 is hollowed out and connected to the hanging hole 22. The hollowed-out middle part of the clamping frame 2 is designed to make the coating tooling lightweight and convenient for clamping personnel to pick up and put down. It also helps to pick up and put down the corner piece hanging bracket 3.

[0031] The hanging bracket 3 includes a main frame 31, an upper hook 32, a lower hook 33, and two movable fixing rods. The upper hook 32 and the lower hook 33 are respectively fixed on the main frame 31. A through slot is opened in the vertical direction of the main frame 31. The two movable fixing rods are symmetrically arranged in the through slot. Each movable fixing rod includes a rod body 34. Both ends of the rod body 34 are threaded with fastening screws 35. The rod body 34 is fixed on the main frame 31 by the fastening screws 35. Several magnets 36 are evenly fixed on the surface of the rod body 34.

[0032] Reference Figure 4 and Figure 5 The three brackets 3 can be distributed in three equal parts on the mounting bracket 2, or they can be distributed in four equal parts on the mounting bracket 2.

[0033] Dividing the piece into three equal parts allows for clamping corner pieces with a diameter of up to 110mm, while dividing it into four equal parts allows for clamping corner pieces with a diameter of up to 85mm.

[0034] The implementation principle of the coating clamping fixture in this application embodiment is as follows:

[0035] During clamping, first place the circular protrusion 12 in the corner piece body 1 between the two movable fixing rods facing the bracket 3. The circular block 11 in the corner piece body 1 can be attracted by the magnet 36. Then, install multiple corner piece bodies 1 onto the bracket 3 in sequence. Finally, adjust the position of the movable fixing rods, and use the circular protrusion 12 to press the corner pieces together. Then, fix the position of the rod body 34 with the fastening screw 35, so that multiple corner pieces can be fixed on the bracket 3.

[0036] During coating, multiple hangers 3 are hung equally on the clamping frame 2. The upper hook 32 of the hanger 3 is aligned with the upper hanging hole 21, and the lower hook 33 is aligned with the lower hanging hole 22. Through the equal arrangement and the cooperation of the movable fixing rod, corner pieces of different sizes and models can be clamped and used at the same time, reducing the cost of fixtures, increasing the furnace loading capacity, and ensuring that the coating area of ​​the corner pieces faces outward, thus guaranteeing the coating quality and uniform coating thickness.
