Description

Technical Field

[0001] This invention relates to the field of vehicle maintenance technology, and more specifically, to an intelligent maintenance line inner hole cleaning unit and a node removal system. Background Technology

[0002] The bogie structure of a rail vehicle contains various suspension components that serve both connecting and damping functions, such as axle box assemblies, traction rod assemblies, suspension rod assemblies, connecting rod assemblies, and leaf spring assemblies. These components are installed in different locations on the rail vehicle bogie, and therefore their structures differ. Even for the same type of suspension component, their structures vary from vehicle to vehicle. Each suspension component includes a rod body and a rubber joint. The rod body has an inner hole, and the rubber joint is press-fitted into the inner hole. During vehicle operation, the rubber joint may fatigue and fail. Therefore, when a rubber joint fails due to fatigue, it needs to be removed from the inner hole and a new rubber joint needs to be press-fitted in.

[0003] Rail vehicles are long, and each vehicle has numerous suspension rods. The removal of rubber joints from these rods is typically done manually with hand tools, which is inefficient and prone to damage to the inner bore due to improper operation or uneven force. After the old joint is removed, before replacing it with a new one, the inner bore needs to be inspected for scratches. If no scratches are found, the grease inside the bore needs to be cleaned, and the bore needs to be polished. Currently, the visual inspection of the inner bore relies on manual inspection, and cleaning is also done manually using sandpaper, cloths, and polishing machines. This results in low production efficiency, non-standard operations, difficulties in dust collection, and the inability to automatically record the condition after polishing.

[0004] In general, the maintenance of existing technical nodes mainly relies on manual operation, which has the disadvantages of non-standard operation, low work efficiency and large workload.

[0005] The invention patent application number 202320248432.9, entitled "Invention Patent for Press-fitting and Unloading Device for Rubber Joints of Vibration Damperes," includes a frame, a slide block, a pressurizing component, and a sliding drive component. The frame has a horizontally extending first track. The slide block is slidably connected to the first track, and two tooling frames are spaced apart along its sliding direction on the slide block. The two tooling frames are used to support the rubber joint mounting parts at both ends of the vibration damper. The pressurizing component is located on the frame, directly above the first track, with its output end facing downwards to apply pressure to the rubber joints. The sliding drive component is located on the frame, with its output end connected to the slide block, used to drive the slide block to slide between a first station and a second station. This invention provides a press-fitting and unloading device for rubber joints of vibration dampers, which can improve maintenance efficiency, reduce labor intensity, and prevent safety accidents caused by improper manual operation.

[0006] Application number 201822081621.3, entitled "Motor Rubber Node Loading and Unloading Mechanism, Unloading Mechanism, and Motor Rubber Node Loading and Unloading Fixture," describes a utility model patent for a motor rubber node loading and unloading mechanism. The mechanism includes a force-applying mechanism, a pressing sleeve, a pressing sleeve support, and a guide sleeve. The pressing sleeve has a first mandrel hole extending through it along the axial direction, through which a mandrel on one side of the rubber node passes. The pressing sleeve support has a guide groove extending along the axial direction of the rubber node mounting hole. The outer edge of the guide sleeve matches the inner wall shape of the motor's rubber node mounting hole, and the guide sleeve has a second mandrel hole extending through it along the axial direction, through which a mandrel on the other side of the rubber node passes. The force-applying mechanism applies a driving force to the pressing sleeve along the axial direction of the rubber node mounting hole, causing the rubber node to enter the mounting hole. This utility model has a simple structure and a relatively simple loading and unloading process, and it can improve the pressing and unloading accuracy of the rubber node.

[0007] The technical solutions of the two patents mentioned above only set up a pressure mechanism to replace manual operation when removing nodes, which reduces the intensity of manual labor. The installation of the product, the recycling of nodes after removal, appearance inspection, cleaning and polishing still rely on manual operation and have not achieved full automation.

[0038] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims. Example 1

The base 100 stands on the ground, the conveyor line 200 is mounted on the base, the retraction fixture plate 300 is placed on the conveyor line 200, and the rod of the metal rubber component is placed on the retraction fixture plate 300. The conveyor line 200 transports the retraction fixture plate 300 to the inner hole cleaning assembly 400. 0. Below the inner hole cleaning component 500 and the inner hole grinding component 600; the inner hole cleaning component 400, the inner hole cleaning component 500, and the inner hole grinding component 600 all include a gantry frame 1, a three-axis drive mechanism, and a cleaning structure 3. The gantry frame is installed on the base 100, the three-axis drive mechanism is installed on the gantry frame 1, and the cleaning structure 3 is installed on the three-axis drive mechanism. The three-axis drive mechanism controls the movement of the cleaning structure 3 in the X, Y, and Z axis directions; the gantry frame 1 supports the cleaning structure 3 above the conveyor line 200, and the cleaning structure 3 cleans the inner hole on the rod.

[0040] In this application, the inner hole cleaning component 400 cleans the grease in the inner hole, the conveyor line 200 then conveys the rod to the inner hole cleaning component 500 to wipe the cleaning agent residue on the inner hole, and finally conveys it to the inner hole grinding component 600 to grind the inner hole.

[0041] like Figure 3 As shown, the three-axis drive mechanism includes an X-axis guide assembly 21, a Y-axis guide assembly 22, and a Z-axis guide assembly 23, respectively. The cleaning structure 3 is connected to the Z-axis guide assembly 23. The X-axis guide assembly 21 includes an X-axis assembly base plate 21a, a drive device 21b mounted on the X-axis assembly base plate 21a, and an X-axis guide rail 21c arranged along the X-axis direction. The Y-axis guide assembly 22 includes a Y-axis assembly base plate 22a, a drive device 22b mounted on the Y-axis assembly base plate 22a, and a Y-axis guide rail 22c arranged along the Y-axis direction. Figure 4As shown, the Z-axis guide assembly 23 includes a Z-axis assembly base plate 23a, a fixing block 23b, a drive device 23c, and a Z-axis adjustment structure 23d; the X-axis assembly base plate 21a is mounted on the gantry 1, and the Y-axis assembly base plate 22a has a guide groove adapted to the X-axis guide rail 21c. The drive device 21b drives the Y-axis assembly base plate 22a to move along the X-axis guide rail 21c; the Z-axis assembly base plate 23a also has a guide groove adapted to the Y-axis guide rail 22c. Drive device 22b drives the Z-axis assembly base plate 23a to move along the Y-axis guide rail 22c; the fixing block 23b of the Z-axis guide assembly 23 is fixed to the Z-axis assembly base plate 23a, and the Z-axis adjustment structure 23d is movably connected to the fixing block 23b; drive device 3 23c drives the Z-axis adjustment structure 23d to move along the Z-axis of the fixing block 23b; the cleaning structure 3 is connected to the Z-axis adjustment structure 23d, and the Z-axis adjustment structure 23d drives the cleaning structure 3 to move along the Z-axis direction.

[0042] like Figure 3 As shown, the X-axis assembly base plate 21a includes two, with an X-axis guide assembly 21 mounted on each X-axis mounting base plate 21a, and the Y-axis assembly base plate 22a is mounted on the two X-axis assembly base plates 21a.

[0043] The drive devices 1 (21b), 22b, and 3 (23c) all include a motor 4 and a synchronous belt and pulley assembly. Drive device 1 (21b) driving the Y-axis assembly base plate 22a to move along the X-axis guide rail 21c means that the motor 4 drives the synchronous belt 5 to rotate, the Y-axis assembly base plate 22a is connected to the synchronous belt 5, and the synchronous belt 5 drives the Y-axis assembly base plate 22a to move (i.e., drives the Y-axis guide assembly 22 to move), and the X-axis guide rail 21c guides the movement of the Y-axis assembly base plate 22a. Drive device 2 (22b) driving the Z-axis assembly base plate 23a to move along the Y-axis guide rail 22c means that the motor 4 drives the synchronous belt 5 to rotate, the Z-axis assembly base plate 23a is connected to the synchronous belt 5, and the synchronous belt 5 drives the Z-axis assembly base plate 23a to move (i.e., drives the Z-axis guide assembly 23 to move), and the Y-axis guide rail 22c guides the movement of the Z-axis assembly base plate 23a.

[0044] The Z-axis adjustment structure 23d includes a connecting seat and a guide rod 23d2. The connecting seat includes a sealing plate 23d11 and adapter plates 23d12 respectively installed at both ends of the sealing plate 23d11. The guide rod 23d2 is fixed between the two adapter plates 23d12. The cleaning structure 3 is fixed to the lower adapter plate 23d12. The lower adapter plate 23d12 has the cleaning structure 3 fixed on its downward side and the guide rod 23d2 fixed on its upward side, and one of the synchronous pulleys 6 of the synchronous belt 5 is installed thereon. The other synchronous pulley 6 of the synchronous belt 5 is installed on the adapter plate 23d12 located at the upper end of the sealing plate 23d11. The motor 4 of the drive device 23c drives the synchronous belt 6 to rotate. The guide rod 23d2 moves through the fixing block 23b, and one side of the synchronous belt 6 is fixed to the fixing block 23b. In use, the drive device 23c drives the synchronous pulley 6 to rotate the synchronous belt 5. The fixed block 23b is fixed to the Z-axis assembly base plate 23a. One side of the synchronous belt 5 is fixed to the fixed block 23b. As the synchronous pulleys 6 at both ends of the synchronous belt 5 rotate, the Z-axis adjustment structure 23d moves up and down along the fixed block 23b, realizing Z-axis adjustment. The guide rod 23d2 is arranged in the Z-axis direction. In this embodiment, two guide rods 23d2 are included.

[0045] like Figure 5 As shown, the fixing block 23b includes an upper reinforcing plate 23b1, a lower reinforcing plate 23b2, a support member 23b3, and a timing belt fixing plate 23b4. The support member 23b3 is fixedly installed between the upper reinforcing plate 23b1 and the lower reinforcing plate 23b2. Both sides of the timing belt 5 pass through the upper reinforcing plate 23b1 and the lower reinforcing plate 23b2. The timing belt fixing plate 23b4 is located between the upper reinforcing plate 23b1 and the lower reinforcing plate 23b2 and fixes one side of the timing belt 5 to the support member 23b3.

[0046] The cleaning structure 3 includes a brush head 31 and a drive device 4.2 32 for rotating the brush head 31. In this embodiment, the brush heads of the inner hole cleaning component 400 and the inner hole cleaning component 500 are nylon brushes, and the brush head of the inner hole polishing component 600 is a copper wire wheel. The inner hole cleaning component 400 also includes a spray system 7, which includes a pressure tank 71 containing cleaning agent, a nozzle 72, and a pipeline connecting the pressure tank 71 and the nozzle 72. The nozzle 72 is fixed to the cleaning structure 3. A sensor is installed on the pressure tank 71, which sends an alarm signal to the control system when the cleaning agent in the pressure tank 71 is insufficient.

[0047] During use, the brush head 31 of the internal cleaning component 400 rotates while the spray system 7 sprays cleaning agent. It should be noted that because the grease in the internal hole is thick, if the cleaning agent is sprayed first and then the brush head 31 is started to clean, a lot of the cleaning agent will have fallen off the grease by the time the brush head 31 starts cleaning, which will affect the cleaning effect. Therefore, it is necessary to spray the cleaning agent while brushing.

[0048] The brush head 31 of the internal hole cleaning assembly 400 rotates rapidly under the drive of the drive device 32. The cleaning agent sprayed on the brush head will cause the cleaning agent to splash everywhere. In order to solve this technical problem, the drive device 32 of the internal hole cleaning assembly 400 is a pneumatic drill. The pneumatic drill includes a pneumatic drill body and a rotating drill bit. The nozzle 72 is fixed to the pneumatic drill body. The nozzle 72 includes a connecting pipe 72a, a cover plate 72b and an air guide cylinder 72c that are fixedly connected and communicated in sequence. The connecting pipe 72a, the cover plate 72b and the air guide cylinder 72c are all hollow structures. The air guide cylinder 72c is close to the brush head 31 and covers the air jet 32a of the pneumatic drill. The nozzle 72 is fixed to the pneumatic drill body through the connecting pipe 72a. The connecting pipe 72a is connected to the pressure tank 71 through a pipeline. The end of the air guide cylinder 72c near the brush head 31 has a nozzle 72d. This embodiment includes four adapter pipes 72a, and six nozzles 72d are opened at the bottom of the air guide tube 72a near the brush head 31. A characteristic of pneumatic drills is that they release air during rotation. The drive device 4 32 in this application uses a pneumatic drill. The pneumatic drill can not only drive the brush head 31 to rotate, but the air it sprays can also be utilized. The air guide tube 72c has a guiding function, enclosing the air jet of the pneumatic drill, causing the air to spray downwards. This prevents the cleaning agent from splashing everywhere during spraying, allowing the cleaning agent and air to fall directionally into the recovery hopper, facilitating the recovery of waste liquid and waste gas.

[0049] The drive device 32 of the inner hole cleaning component 400 and the inner hole grinding component 500 is also the pneumatic drill, and the nozzle 72 is also fixed on the pneumatic drill. However, the adapter pipe 72a of the nozzle 72 of the inner hole cleaning component 500 and the inner hole grinding component 600 is connected to high-pressure gas. In this application, the inner hole cleaning component 400 needs to use a cleaning agent, and its adapter pipe 72a is connected to a pressure tank 71 containing the cleaning agent. The inner hole cleaning component 500 cleans the residual cleaning agent in the inner hole, and its adapter pipe 72a is connected to high-pressure gas to blow away the residual liquid. After the inner hole is cleaned, it enters the next station below the inner hole grinding component 600. The brush head 31 of the inner hole grinding component 600 grinds the inner hole, and the adapter pipe 72a of the inner hole grinding component 600 is connected to high-pressure gas to blow the generated metal dust into the recycling hopper 8 below. In this embodiment, the cleaning agent used is a volatile liquid, but it does not completely evaporate and will remain in the inner hole of the rod. Therefore, it needs to be dried with high-pressure gas.

[0050] A recycling hopper 8 is provided on the machine base 100 and below the inner hole cleaning assembly 400, the inner hole cleaning assembly 500, and the inner hole grinding assembly 600. A recycling system 9 is also provided in the machine base 100, and the recycling system 9 is connected to the recycling hopper 8 through a pipeline. Furthermore, a filter screen is provided at the bottom of the recycling hopper 8 to prevent screws and dust that fall during production from entering the recycling system 9.

[0051] Each of the internal hole cleaning assembly 400, internal hole polishing assembly 500, and internal hole grinding assembly 600 is equipped with a recovery hopper 8. The recovery hopper 8 is connected to a recovery system 9, which includes a gas-liquid separator 91, an extraction device 92, and a dust collector 93. The gas-liquid separator 91 is connected to the recovery hopper 8 below the internal hole cleaning assembly 400 and is also connected to the extraction device 92. A liquid level sensor is installed on the gas-liquid separator 91. When the gas-liquid separator 91 is full, the valve is manually opened to discharge the residual liquid. The dust collector 93 is connected to the recovery hopper 8 of the internal hole cleaning assembly 500 and the internal hole grinding assembly 600. The internal hole cleaning assembly 400 sprays cleaning agent, resulting in a relatively large amount of waste liquid. Therefore, a gas-liquid separator 91 is installed below the recovery hopper 8 to retain the liquid, while the gas is extracted by the extraction device 92. The internal hole cleaning component 500 dries the residual cleaning agent on the internal hole, releasing gas and a small amount of residual cleaning agent, which can be absorbed by the dust collector 93. The internal hole grinding component 600 discharges air and a small amount of metal dust, which can be collected by the dust collector 93. Example 2

[0052] A node removal system includes the node intelligent inspection line inner hole cleaning unit described in Embodiment 1. The conveyor line 200 is also equipped with a node removal component 700 for removing nodes, an inner hole detection component 800 for visual inspection of the inner hole of the rod, and an old node recycling component 900 located below the node removal component for recycling old nodes. The node removal component 700 includes a press mounted on the base 100.

[0053] like Figure 2As shown, the internal hole detection component, press, internal hole cleaning component 400, internal hole cleaning component 500, and internal hole grinding component 600 are arranged sequentially. The internal hole detection component 800 is installed on the side of the press away from the internal hole cleaning component 400. The internal hole detection component 800 includes a camera component and the Z-axis guide component 23 described in Embodiment 1. The Z-axis component base plate 23a is fixed to the press, the fixing block 23b is fixed to the Z-axis component base plate 23a, the Z-axis adjustment structure 23d is movably connected to the fixing block 23b, and the camera component 10 is connected to the Z-axis adjustment structure 23d. The camera component is fixed to the lower adapter plate 23d12. The lower adapter plate 23d12 has the camera component 10 fixed on its downward side and the guide rod 23d2 fixed on its upward side, and one of the synchronous pulleys 6 of the synchronous belt 5 is installed thereon.

[0054] In this embodiment, the inner hole detection component 800 is installed on the side of the press away from the inner hole cleaning component 400, which can prevent the cleaning fluid of the inner hole cleaning component 400 from contaminating the camera when cleaning the inner hole.

[0055] The old node removal assembly of this application removes the old node from the inner hole of the rod. The old node falls into the old node recycling assembly 900 below the old node removal assembly 700. The conveyor line 200 transports the rod to the inner hole inspection assembly 800 to inspect the appearance of the inner hole. If there are scratches or other damage in the inner hole, the robot arm removes the rod for repair. If there are no scratches or other damage in the inner hole, the conveyor line 200 transports the rod to the inner hole cleaning assembly 400 to clean the grease in the inner hole. The conveyor line 200 then transports the rod to the inner hole cleaning assembly 500 to wipe off the cleaning agent residue on the inner hole. Finally, it is transported to the inner hole grinding assembly 600 to grind the inner hole.

[0056] Holes are sequentially formed on the unloading tooling plate 300 and machine base 100 below the press of the unloading node assembly 700. The size of the holes is larger than the outer diameter of the node, so that the old node falls from the holes into the old node recycling assembly 900 after being punched out. Protective covers A are also provided at the stations of the press, the inner hole cleaning assembly 400, the inner hole cleaning assembly 500, and the inner hole grinding assembly 600 to enclose the four stations, leaving one end of the outlet for the conveyor line 200 to enter and exit.
