[0034] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings. Figs. 1-2 The embodiments of the technical solutions of the present application will be described in detail below. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0035] Embodiment 1:

[0036] As Figs. 1-2 The present application illustrates a conveying disc for a railway bearing maintenance production line. In order to orderly place the bearing parts and prevent the loss of original installation position information, the present application defines a bearing inner ring bearing area, an informationized identification area, and a roller cage assembly area by setting a guide groove in the annular outer ring positioning assembly, which facilitates the placement of each part of the railway bearing. The conveying disc includes a bearing tray body 10 in the form of a rectangular frame structure without a top cover, double-sided guide grooves 11 arranged opposite along the x direction of the tray body 10, and an annular outer ring positioning assembly 20 integrated on the upper surface of the tray body 10 and vertically connected to the end of the guide groove 11. The annular outer ring positioning assembly 20 and the guide groove 11 jointly define an axially symmetric distributed bearing inner ring bearing area 30, an informationized identification area 40, and a roller cage assembly area 50. The inner ring bearing area 30 and the informationized identification area 40 are arranged on the transverse sides of the annular positioning assembly 20, and the roller cage assembly area 50 is located radially outside the annular positioning assembly 20.

[0037] In actual use, the staff can place each part of the railway bearing on the conveying disc according to specific placement rules. The bearing inner ring is placed in the bearing inner ring bearing area 30, the informationized identification area 40 can be used to place a two-dimensional code paper sheet for identifying bearing information, and the roller cage is placed in the roller cage assembly area 50. Since the conveying disc clearly divides different areas, each part of the bearing can be placed in order, avoiding the situation of scattered stacking of parts, thereby preventing the loss of original installation position information and ensuring traceability.

[0038] Embodiment 2:

[0039] As Figs. 1-2The application illustrates a conveying disc for a railway bearing maintenance and production line, in order to stably place the bearing outer ring and improve the conveying stability, the annular outer ring positioning assembly 20 of the application comprises a main positioning baffle 21 and a secondary positioning baffle 22 which are vertically fixed to the terminal end surface of the guide groove 11, a limiting plate 23 which connects the free ends of the main positioning baffle 21 and the secondary positioning baffle 22, and the main positioning baffle 21, the secondary positioning baffle 22 and the limiting plate 23 form a C-shaped embracing structure, the opening direction of which is parallel to the axial direction of the guide groove 11, and the opening end surface of the C-shaped embracing structure is in butt joint with the inner side wall surface of the guide groove 11.

[0040] When the bearing outer ring is placed on the conveying disc, the C-shaped embracing structure formed by the main positioning baffle 21, the secondary positioning baffle 22 and the limiting plate 23 can embrace and fix the bearing outer ring. At the same time, the opening end surface of the C-shaped embracing structure is in butt joint with the inner side wall surface of the guide groove 11, which further enhances the embracing effect, so that the bearing outer ring can be stably placed on the conveying disc during the conveying process, the conveying stability is improved, and the risk of shaking or falling of the bearing outer ring during the conveying process is reduced.

[0041] At the same time, the working surface intersection of the main positioning baffle 21 and the secondary positioning baffle 22 is provided with a guide inclined surface 24 with an inward angle of 3°-5°.

[0042] During the conveying process, if the conveying disc is unstable, the bearing outer ring may be radially offset. However, the guide inclined surface 24 at the working surface intersection of the main positioning baffle 21 and the secondary positioning baffle 22 can play a restraining role. When the bearing outer ring has a tendency to roll outwards, the inward angle of the guide inclined surface 24 will hinder the rolling of the bearing outer ring, preventing it from rolling out of the annular outer ring positioning assembly 20, thereby enhancing the safety of the conveying process.

[0043] Embodiment 3:

[0044] As Figs. 1-2 The application illustrates a conveying disc for a railway bearing maintenance and production line, in order to realize the passability of the conveying disc and fix bearing outer rings of different sizes, the secondary positioning baffle 22 of the application is in adjustable sliding connection with the limiting plate 23 through the dovetail groove guide rail mechanism 25, and the main positioning baffle 21 is rigidly fixed with the limiting plate 23 by means of the countersunk head screw 26.

[0045] Since the secondary positioning baffle 22 can be adjusted by sliding on the limiting plate 23 through the dovetail groove guide rail mechanism 25, and the main positioning baffle 21 is rigidly fixed with the limiting plate 23. In this way, when facing bearing outer rings of different sizes, the position of the secondary positioning baffle 22 can be adjusted to change the distance between the main positioning baffle 21 and the secondary positioning baffle 22, thereby realizing the fixation of bearing outer rings of different sizes and improving the versatility and passability of the conveying disc.

[0046] At the same time, in order to enhance the adjustment space of the secondary positioning baffle, more sizes of bearing outer rings can be applied,

[0047] The primary positioning baffle 21 is arranged adjacent to the informationized identification area 40, and the secondary positioning baffle 22 is arranged adjacent to the inner ring bearing area 30, and the distance between the axes of the two baffles is in a tolerance fit with the diameter of the standard bearing outer ring.

[0048] The primary positioning baffle 21 is arranged on the side close to the inner ring bearing area 30, and the secondary positioning baffle 22 is arranged on the side close to the informationized identification area 40. This layout can maximize the range that the secondary positioning baffle 22 can slide without affecting the space for placing identification objects such as two-dimensional code paper sheets. By increasing the adjustment space of the secondary positioning baffle 22, the annular outer ring positioning assembly 20 can accommodate a wider range of bearing outer ring sizes, further enhancing the applicability of the conveying disc. At the same time, if the bearing size is larger, the space of the informationized identification area 40 can be further squeezed by sliding the secondary positioning baffle 22, and the two-dimensional code for determining bearing information can be directly placed in the bearing inner ring.

[0049] Embodiment 4:

[0050] As Figs. 1-2 A conveying disc for a railway bearing maintenance production line is illustrated. In order to facilitate the taking of the conveying disc and improve the convenience of operation, the other two side walls of the tray body 10 where the guide grooves 11 are not arranged are provided with gripping grooves 60.

[0051] In actual operation, the conveying disc can be taken by holding the carrying gripping grooves 60. Since the carrying gripping grooves 60 are designed in accordance with ergonomics, the hands of the worker can hold the conveying disc more comfortably, thereby facilitating the taking and carrying of the conveying disc and improving the convenience of operation.

[0052] In the description of the embodiments of the present application, the orientation or positional relationship indicated by the technical terms "upper", "lower", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the embodiments of the present application and simplifying the description, and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.
