[0002] The bearing is the part of the sliding bearing that directly contacts the shaft. It is very smooth and is generally made of wear-resistant materials such as bronze and anti-friction alloy. It is in the shape of a semi-cylindrical surface in the shape of a tile. Its function is to bear the force applied by the journal, maintain the stability of the oil film, make the bearing work smoothly and reduce the friction loss of the bearing. As modern engines develop towards lightweight, high speed, high load and long life, the requirements for the mechanical properties and service life of the bearing are also increasing. The use of surface coating technology can solve the problems of traditional bearings that are not wear-resistant and have a large friction coefficient, effectively improve the service life of the workpiece, and at the same time ensure the reliability of the equipment, greatly reduce maintenance costs and improve safety.

[0038] Figure 2 It is a structural schematic diagram of a fixing member of a specific embodiment of the utility model. Figure 3 This is an exploded view of a fixing member of a specific embodiment of the utility model, combined with Figure 2 and Figure 3 The fixing part 2 includes a base plate 21 and a plurality of limit plates 22 arranged on the base plate 21. Limit blocks 23 are arranged at the ends of both sides of the limit plates 22. An open cavity for placing the bearing to be plated is formed between the limit plates 22, the limit blocks 23 and the base plate 21. The limit plates 22 and the limit blocks 23 are respectively fitted with the outer side surfaces and both side end surfaces of the bearing to be plated, so that the bearing to be plated can be fixed in the open cavity, thereby realizing the clamping of multiple bearings, which is convenient and reliable.

[0039] In a specific embodiment, the outer periphery of the base plate 21 is evenly cut into a number of semicircular rings with openings facing outward, and a limiting plate 22 is correspondingly arranged on each semicircular ring. The limiting plates 22 are evenly arranged along the outer periphery of the base plate 21, so that the inner side surfaces of the bearings to be plated face outward and are evenly fixed on the outer periphery of the base plate 21 to facilitate coating of the inner side surfaces.

[0040] In a specific embodiment, the width of the limit block 23 is not longer than the thickness of the bearing to be plated, which ensures the fixation of the bearing to be plated while preventing the limit block 23 from protruding to the inner side of the bearing to be plated and affecting the coating.

[0044] In a specific embodiment, a through hole 31 is provided at the center of the support rod 3 , so that the fixing portion 11 of the fixing shaft 1 can penetrate into the support rod 3 .

[0045] In a specific embodiment, the outer ring size of the support plate 12 is larger than the outer ring size of the support rod 3. The upper surface of the support plate 12 can resist the lower surface of the support rod 3 to limit the support rod 3 and prevent it from falling under the action of gravity, thereby indirectly providing strong support for the bearing to be plated.

[0046] Combination Figure 6In a specific embodiment, a through hole 24 is opened in the center of the bottom plate 21. The through hole 24 has a shape and size that is compatible with the fixing portion 11 of the fixed shaft 1, so that the fixing portion 11 can penetrate into the center of the fixing member 2 and can drive the fixing member 2 to rotate around the axis, thereby causing several bearings to be plated to rotate around the axis.

[0047] In a specific embodiment, a through hole 31 is opened in the center of the support rod 3. The size of the through hole 31 is smaller than the size of the base plate 21, but not smaller than the size of the fixing portion 11 of the fixed shaft 1, so that the fixed shaft 1 can pass through the support rod 3, and the upper surface of the support rod 3 can be against the lower surface of the base plate 21. The fixing part 2 is fixed at a specified height under the action of gravity and the support of the support rod 3 to achieve positioning, so that the bearing to be plated is raised to a specified height for coating.

[0049] In a specific embodiment, the periphery of the bottom plate 21 is evenly cut into five semicircular rings with openings facing outwards. The outer diameter Φ of the semicircular rings on the periphery of the bottom plate 21 is 40 mm, and the inner diameter φ is 30 mm. A stop plate 22 is correspondingly arranged on each semicircular ring. The five stop plates 22 are evenly arranged along the periphery of the bottom plate 21. The height of the stop plate 22 is 20 mm, and its cross section is also a semicircular ring. The outer radius R is 20 mm, and the inner radius r is 18.27 mm. The ends of both sides of each stop plate 22 are connected to the stop blocks 23. The stop blocks 23 have a height of 20 mm, a length of 2 mm, and a width of 2 mm.

[0050] In a specific embodiment, there are multiple fixing parts 2, and the multiple fixing parts 2 are stacked and strung on the fixed shaft 1.

Multiple bearings to be plated are placed in the open cavity of the fixing 2, and their outer side surfaces and both side end surfaces are respectively fitted with the limit plate 22 and the limit block 23, and fixed with the help of gravity. The coating equipment cooperates with the connecting part 13 of the fixed shaft 1, and drives the fixed shaft 1 to rotate through the driving device. The cross-sectional shape of the fixed part 11 of the fixed shaft 1 and the shape of the through hole 24 of the fixing part 2 are both D-shaped, so that the fixing part 2 rotates synchronously with the fixing part 11, and then the bearing to be plated can also rotate synchronously with the fixing part 11, so that the film layer is evenly plated on the inner surface of each bearing, improving the quality of the bearing body. The bearing fixture provided by the present application provides a special fixture for bearing coating, which avoids the inconvenience of manual padding, is more convenient and reliable for clamping, and is more convenient for disassembly.
