Description
Technical Field
[0001] This utility model relates to the technical field of bearing maintenance and scheduling, and in particular to a production line diversion and transmission device for bearing maintenance. Background Technology
[0002] The maintenance of railway freight car bearings involves a multi-stage inspection process, requiring the bearings to be transferred between workstations via an automated conveyor line. Due to the complex bearing structure and numerous maintenance procedures (typically including more than 10 steps such as visual inspection, dimensional measurement, and flaw detection), a long-distance chain conveyor system is needed to ensure precise component transport. Constrained by the space layout of the maintenance depot, the conveyor line must employ a three-dimensional design (such as a double-layer conveyor platform) for space optimization, and intelligent buffer storage areas should be set up at key process connection points to balance the differences in production cycle time between workstations.
[0003] The existing conveying system suffers from the following technical bottlenecks:
[0004] Insufficient intelligent integration of processes: The transfer of bearings between different inspection items relies on manual intervention, and the intelligent linkage between inspection items and conveyor lines has not been completed, resulting in low material flow efficiency;
[0005] Human-machine collaboration poses significant risks: manual handling is prone to causing bearing raceway collisions (statistics show that surface damage caused by manual handling accounts for 37%), seal contamination, and other quality problems, requiring 2-3 additional rework steps for subsequent repairs;
[0006] Insufficient flexibility: Fixed conveyor lines are difficult to adapt to the maintenance needs of multiple bearing models mixed on the line, and the frequency of tooling and fixture replacement increases by more than 40%. Utility Model Content
[0007] The purpose of this invention is to solve the problem in the prior art where the transfer of bearings between different inspection items during bearing maintenance relies on manual intervention, resulting in low material flow efficiency.
[0008] To achieve the above objectives, this application proposes a production line diversion and transmission device for bearing maintenance, comprising:
[0009] The base platform adopts a rectangular frame structure and has symmetrically distributed roller conveyor mounting reference surfaces on its top surface;
[0010] The diversion conveying assembly includes roller conveyor units symmetrically fixed to the roller conveyor mounting reference surfaces on both sides of the base platform, and a segmented modular central guide platform disposed between the two roller conveyor units.
[0011] and a conveyor tray disposed on the diversion and conveying assembly, wherein the edge of the conveyor tray is provided with a groove;
[0012] The central guide platform is composed of several hollow support platform modules spliced together along the conveying direction. The top surface of each hollow support platform module is provided with: a first guide groove arranged in parallel; a reversing conveyor belt disposed in the first guide groove; an end guide groove disposed at the end of the conveying direction formed after the modules are spliced; and a reversing blocking mechanism disposed in the end guide groove.
[0013] The diversion and transmission equipment for the production line used for maintenance in this application automatically diverts the conveyor trays by setting diversion and transmission components on the base platform. The reversing conveyor belt in the first guide groove cooperates with the reversing blocking mechanism to realize the conversion of the conveying direction of the conveyor tray. When the tray moves to the top of the reversing conveyor belt, it is blocked by the reversing blocking mechanism, and then the transport direction is changed along the conveying direction of the reversing conveyor belt to enter the next process. This solves the problem in the prior art that the bearing transfer between different inspection items during bearing maintenance relies on manual intervention, and the intelligent linkage between inspection items and the conveyor line is not completed, resulting in low material flow efficiency.
[0014] Furthermore, in order to set up an intelligent buffer storage area at the connection node to balance the differences in production cycle time of each workstation, the diversion conveyor component includes: a main conveyor belt extending longitudinally along the base platform; and a diversion conveyor belt connected to the main conveyor belt at an angle of 30°-90°.
[0015] Furthermore, in order to reduce the resistance encountered during transport by the reversing conveyor belt, the width of the first guide groove is fitted with the width of the reversing conveyor belt with a clearance.
[0016] Furthermore, in order to improve the stability of the conveyor pallet during transportation, the bottom surface of the conveyor pallet is provided with guide flanges on both sides that match the roller spacing of the roller conveyor unit, and the lateral dimension of the guide flanges is greater than the axial spacing of the roller conveyor unit.
[0017] Furthermore, in order to reduce the obstruction of the conveyor disc by the roller conveyor unit when it is on the reversing conveyor belt, the reversing conveyor belt is two parallel synchronous belts, and the top surface of the reversing conveyor belt is 1-2mm higher than the top surface of the central guide table.
[0018] Furthermore, in order for the reversing blocking mechanism to be fully embedded in the end guide groove when not in operation, so as to prevent obstruction of the conveying tray during normal transport, the hinge axis of the reversing blocking mechanism is located at the front edge of the end guide groove in the transport direction.
[0019] Furthermore, to facilitate the retraction when the reversing blocking mechanism is not in operation, a U-shaped mounting base is fitted into the end guide groove. The two side walls of the U-shaped mounting base are provided with concentric shaft holes. The reversing blocking mechanism is hinged through a pin passing through the shaft hole. The groove on the side wall of the conveying tray has a trapezoidal cross section, which forms a surface contact with the wedge-shaped end of the reversing blocking mechanism.
[0020] Furthermore, in order to prevent the U-shaped mounting base from wobbling vertically in the end guide groove, the two end extensions of the U-shaped mounting base are embedded in the hollow cavity of the central guide platform, and the length of the extension is 5-8mm longer than the end guide groove.
[0021] Furthermore, in order to improve the stability of the conveyor tray during transport and avoid violent shaking when blocked by the reversing blocking mechanism, the bottom of the groove is provided with a buffer pad, the thickness of which is 0.5-1mm larger than the width of the end of the reversing blocking mechanism.
[0022] Furthermore, in order to increase the fault tolerance space when the reversing blocking mechanism cooperates with the conveyor plate, the width of the groove is greater than the width of the end of the blocking device.
[0023] The beneficial effects of this application are as follows:
[0024] 1. The diversion and transmission equipment for the production line used for maintenance in this application automatically diverts the conveyor trays by setting diversion and transmission components on the base platform. The reversing conveyor belt in the first guide groove cooperates with the reversing blocking mechanism to realize the conversion of the conveying direction of the conveyor tray. When the tray moves to the top of the reversing conveyor belt, it is blocked by the reversing blocking mechanism, and then the transport direction is changed along the conveying direction of the reversing conveyor belt to enter the next process. This solves the problem in the prior art that the bearing transfer between different inspection items during bearing maintenance relies on manual intervention, resulting in low material flow efficiency.
[0025] 2. The bottom of the conveyor plate of this application is provided with a guide flange that matches the roller spacing, which can be used with the roller conveyor unit to achieve a smoother conveying. At the same time, the buffer pad set in the groove of the conveyor plate can further improve the smoothness when the conveyor plate contacts the reversing blocking mechanism, so as to improve the stability of the bearing components in the conveyor plate.
[0026] 3. When not in operation, the reversing blocking mechanism of this application can be embedded in the end guide groove without affecting the conveying of the conveyor tray. Therefore, it can improve the versatility of the modular central guide table, that is, the modular central guide table can be assembled arbitrarily to realize the setting of conveyor lines of different lengths.
[0027] 4. This application allows for flexible configuration of the main conveyor belt and the branch conveyor belt, and allows for the configuration of any number of branch conveyor belts, thereby enabling the setting of intelligent buffer storage areas at key process connection nodes to balance the differences in production cycle time of each workstation.

[0037] The following will be combined with the appendix Figures 1-3 The embodiments of the technical solutions of this application are described in detail below. The following embodiments are only used to more clearly illustrate the technical solutions of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other. Example
[0038] like Figures 1-2This illustration depicts a bearing maintenance production line diversion and transmission device. To achieve automatic diversion of the bearing maintenance conveyor line and improve material flow efficiency, the bearing maintenance production line diversion and transmission device of this application includes a base platform 1, which adopts a rectangular frame structure and has symmetrically distributed roller conveyor mounting reference surfaces on its top surface; a diversion and transmission assembly 2, comprising roller conveyor units 21 symmetrically fixed to the roller conveyor mounting reference surfaces on both sides of the base platform 1, and a segmented modular central guide platform 22 disposed between the two roller conveyor units 21; a conveyor tray 4 disposed on the diversion and transmission assembly 2, with grooves 41 provided on the edge of the conveyor tray 4; the central guide platform 22 is composed of several hollow support platform modules 221 spliced along the conveying direction, and each hollow support platform module 221 has a first guide groove 222 arranged in parallel on its top surface, a reversing conveyor belt 31 disposed in the first guide groove 222, an end guide groove 223, and a reversing blocking mechanism 32 disposed in the end guide groove 223.
[0039] When the conveyor pallet 4 is conveyed on the roller conveyor unit 21, if a change of conveying direction is required, when the pallet moves to the top of the reversing conveyor belt 31, the reversing blocking mechanism 32 will prevent the conveyor pallet 4 from continuing to move in the original direction. Driven by the reversing conveyor belt 31, the conveyor pallet 4 changes its transport direction along the conveying direction of the reversing conveyor belt 31 and enters the diversion conveyor belt 101 corresponding to the next process. In this way, by setting the diversion conveyor component 2 on the base platform 1 to complete the automatic diversion of the conveyor pallet 4, the problem of low material flow efficiency caused by the reliance on manual intervention for bearing transfer between different inspection items during bearing maintenance in the prior art, which fails to achieve intelligent linkage between inspection items and the conveyor line.
[0040] Meanwhile, in order to achieve intelligent buffering and storage of key process connection nodes and balance the differences in production cycle time of each station, the diversion conveyor component 2 includes a main conveyor belt 100, which extends longitudinally along the base platform 1; and a diversion conveyor belt 101, which is connected to the main conveyor belt 100 at an angle of 30° - 90°.
[0041] The main conveyor belt 100 and the diversion conveyor belt 101 can be flexibly adjusted according to actual production needs. By setting different numbers and angles of diversion conveyor belts 101, bearings can be diverted to different inspection processes, achieving intelligent buffering and storage at key process connection nodes. When the production speed of a certain station is slow, bearings produced at other stations can be stored on the diversion conveyor belt 101 and transported when that station is idle, thereby balancing the differences in production cycle time between stations and improving the efficiency of the entire production line. Example
[0042] like Figures 1-2This illustration shows a production line diversion and transmission device for bearing maintenance. In order to improve the stability of the conveyor pallet during transportation, the device structure is as follows: the bottom surface of the conveyor pallet 4 is provided with guide flanges 42 on both sides that match the roller spacing of the roller conveyor unit 21, and the lateral dimension of the guide flanges 42 is larger than the axial spacing of the roller conveyor unit 21; the bottom of the groove 41 is provided with a buffer pad, the thickness of which is 0.5-1mm larger than the width of the end of the reversing blocking mechanism 32.
[0043] The guide flange 42 is matched with the roller spacing of the roller conveyor unit 21, which can work with the roller conveyor unit 21 to achieve smoother conveying and make the conveyor pallet 4 less prone to shaking during conveying. When the conveyor pallet 4 comes into contact with the reversing blocking mechanism 32, the buffer pad can play a buffering role, reducing the impact force on the conveyor pallet 4, further improving the stability of the conveyor pallet 4 during transportation, and ensuring the stability of each component of the bearing in the conveyor pallet 4. Example
[0044] like Figures 1-2 This illustration shows a production line diversion and transmission device for bearing maintenance according to this application. In order to improve the versatility of the modular central guide table, the hinge axis of the reversing blocking mechanism 32 is located at the front edge of the conveying direction of the end guide groove 223. A U-shaped mounting seat 33 is fitted in the end guide groove 223. The two side walls of the U-shaped mounting seat 33 are provided with concentric shaft holes. The reversing blocking mechanism 32 is hinged by a pin through the shaft hole. The extensions 331 at both ends of the U-shaped mounting seat 33 are embedded in the hollow cavity of the central guide table 22, and the length of the extensions 331 is 5-8mm longer than that of the end guide groove 223.
[0045] The hinged axis design of the reversing blocking mechanism 32 allows it to be fully embedded in the end guide groove 223 when not in operation, preventing obstruction of the conveyor tray 4 during normal transport. The U-shaped mounting base 33 facilitates the installation and removal of the reversing blocking mechanism 32, while the extension 331, embedded in the hollow cavity of the central guide table 22, prevents the U-shaped mounting base 33 from wobbling vertically within the end guide groove 223. Thus, the modular central guide table 22 can be assembled arbitrarily to accommodate conveyor lines of different lengths, enhancing its versatility.
[0046] To improve the tolerance space when the reversing blocking mechanism and the conveyor pallet cooperate, the device structure features a groove 41 with a width greater than the end width of the reversing blocking mechanism 32. The groove 41 on the side wall of the conveyor pallet 4 is wider than the end width of the reversing blocking mechanism 32, providing greater tolerance space for their cooperation. In actual production, various factors may cause slight deviations in the position of the conveyor pallet 4. The larger groove 41 ensures that the reversing blocking mechanism 32 can accurately cooperate with the conveyor pallet 4 to achieve the reversing function, thus improving the reliability and stability of the equipment. Example
[0047] like Figures 1-2 This invention illustrates a production line diversion and transmission device for bearing maintenance. In order to reduce the obstruction of the conveyor tray by the roller conveyor unit when it is on the reversing conveyor belt, the device structure is as follows: the reversing conveyor belt 31 consists of two parallel synchronous belts, and the top surface of the reversing conveyor belt 31 is 1-2 mm higher than the top surface of the central guide table 22.
[0048] The reversing conveyor belt 31 is set as two parallel synchronous belts, and its top surface is 1-2mm higher than the top surface of the central guide platform 22. This allows the conveying pallet 4 to smoothly disengage from the roller conveyor unit 21 when it is on the reversing conveyor belt 31, reducing the obstruction of the roller conveyor unit 21 on the conveying pallet 4 when it is on the reversing conveyor belt 31, and ensuring that the conveying pallet 4 can complete the reversing conveying smoothly.
