Description

Technical Field

[0001] This invention relates to the field of vehicle maintenance technology, and more specifically, to an air-suspension sliding platform and a joint assembly / disassembly system for pressing and installing rubber joints. Background Technology

[0002] The bogie structure of rail vehicles contains various suspension members 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 member, the structure varies between different vehicles. Each suspension member consists of 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 can 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. Rail vehicles are long, and each rail vehicle has a large number of suspension members. The removal of the rubber joints from these suspension members is usually done manually using a hand-held removal tool. This method is inefficient and prone to damage to the inner hole of the rod body due to improper operation or uneven force.

[0003] 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.

[0004] This patent uses a pressurizing component to replace manual pressure on the rubber nodes, causing them to retract or be pressed in. The pressurizing component and the rubber nodes are arranged vertically. To achieve automation, a sliding drive is also included to move the rubber nodes below the pressurizing component. The patent's shortcoming lies in its insufficient load-bearing capacity. Specifically, the retraction or pressing of the metal rubber nodes requires tens of tons of force. The patent's structure includes a sliding block on the frame, driven by the sliding drive, with mounting parts on the sliding block to support the rubber nodes at both ends of the shock absorber. Therefore, when the press applies pressure, tens of tons of pressure act vertically on the sliding block, the sliding drive, and the frame. Since conveyor lines typically use chains or synchronous belts, the sliding drive should also be a chain or synchronous belt. When the pressurizing component applies pressure, the tens of tons of retraction pressure also act on the sliding block, the conveyor line, and the frame. The conveyor line cannot withstand such pressure, resulting in insufficient load-bearing capacity.

[0005] 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.

[0006] This patent relates to the installation and removal of motor rubber nodes. The force application mechanism, press sleeve, rubber node, and guide sleeve are arranged laterally. Like the previous patent, it replaces manual operation by setting up a pressure mechanism. The difference from the previous patent is that the force application mechanism applies pressure laterally. Although this patent can solve the technical problems of the previous patent, the tooling is not universal in terms of its structure and is not applicable to all products listed in this background technology. Summary of the Invention

[0007] The technical problem to be solved by the present invention is that the pressure of the node removal and installation is applied to the slide, conveyor line and frame, the conveyor line cannot withstand the pressure of tens of tons, the load-bearing capacity is insufficient, and the node removal and installation tooling is not universal. The present invention provides an air suspension sliding platform and node removal and installation system.

[0008] The above-mentioned objectives of the present invention are achieved through the following technical solutions:

[0009] An air-suspended sliding platform for pressing and fitting rubber joints includes a suspension assembly, an inflation device, and a guide seat. The suspension assembly includes a base plate, slide bars disposed on the base plate, a sliding seat, and a drive device. The slide bars are fixed in pairs on the base plate, and the sliding seat is located between the two slide bars. The drive device drives the sliding seat to move, and the two slide bars guide the movement of the sliding seat. The sliding seat has an inflation hole, and the bottom of the sliding seat in contact with the base plate has an air guide groove, connecting the inflation hole to the inflation device. Inflating the inflation hole with air from the inflation device allows the sliding seat to detach from the base plate and float. The guide seat is fixed on the sliding seat, and a joint removal fixture and a joint installation fixture are installed on the guide seat.

[0010] Furthermore, the drive device includes a motor, a reducer, a transmission component, a timing belt, and a connecting seat connected in sequence. The transmission component includes a long shaft, with a timing belt connected to each end of the long shaft. The two timing belts are located on both sides of the sliding seat, and a connecting seat is fixed on each timing belt. The connecting seat is fixed to the sliding seat. The power of the motor drives the sliding seat to move through the transmission component, the timing belt, and the connecting seat.

[0011] Furthermore, it also includes a guide anti-fool seat and a second drive device installed on the sliding seat. The guide anti-fool seat includes two halves, which are located on both sides of the guide seat. The shape of the guide anti-fool seat facing the tooling is adapted to the shape of the tooling. During stamping, the second drive device drives the two halves of the guide anti-fool seat to hold the tooling tightly.

[0012] Furthermore, an oil-proof cover is also installed on the guide anti-fool seat, which extends from the guide anti-fool seat and covers the top of the second drive device.

[0013] Furthermore, the sliding seat includes a slider and a slider adapter plate fixed to each other. The slider is located below and contacts the base plate, and the slider adapter plate is located above the slider strip. The width of the slider adapter plate is greater than the distance between the two slider strips to facilitate connection with the connecting seat; the air guide groove is located on the slider.

[0014] Furthermore, a support seat is also provided on the base plate. The support seat is located on one side of the guide seat. The support seat and the tooling installed on the guide seat jointly support the workpiece. The support seat includes a bracket, a drive device three and a rotating shaft. A roller is installed at the top of the bracket and the bottom of the bracket is movably connected to the rotating shaft. The rotating shaft is driven to rotate by the drive device three to realize the raising and lowering of the support seat.

[0015] The present invention also provides a metal rubber part node pressing system, including a base, a conveying device, a press, and a node mounting fixture. The conveying device is the air-suspended sliding platform for rubber node stamping and pressing described above. The conveying device and the press are both mounted on the base. The node mounting fixture is mounted on the conveying device. The workpiece is placed on the node mounting fixture. The conveying device moves the workpiece to below the press.

[0016] Furthermore, it also includes an oiling robot, which is mounted on the base plate and located on the outer side of one end of the base plate.

[0017] Furthermore, it also includes a protective cover assembly, which is installed on the base. The oiling robot, guide seat, and support seat are arranged in sequence. During stamping, the protective cover assembly encloses the oiling robot, guide seat, and press. The enclosure has an opening on one side in the moving direction of the conveying device, and the support seat is exposed through the opening. The protective cover assembly consists of multiple door panels, and each door panel is equipped with a lock.

[0018] The present invention also provides a metal rubber part node removal system, including a base two, a conveying device two, a press two, and a node mounting fixture. The conveying device two is the air-suspended sliding platform for rubber node stamping and pressing described above. The conveying device two and the press two are both mounted on the base two. The node mounting fixture is mounted on the conveying device two. The workpiece is placed on the node mounting fixture. The conveying device two moves the workpiece to below the press two.

[0019] The present invention has the following beneficial effects:

[0020] This invention provides an air-suspended sliding platform (hereinafter referred to as the air-suspended sliding platform) for pressing and fitting rubber nodes. During movement, air is injected, allowing the base plate supporting the tooling and product to suspend. Precise displacement can be achieved with only a small thrust. After reaching the desired position, the air is released, and the base plate is rigidly connected to the slider, thus enabling it to withstand sufficient pressure over a long period without deformation. Existing technologies require conveyor lines (such as chains), but chains cannot withstand the impact pressure of tens of tons. This invention solves the technical problem of insufficient load-bearing capacity in existing technologies. In use, the air-suspended sliding platform is inflated into the slider. Air enters the air guide groove at the bottom of the slider, causing it to float. The height of the float is determined by the lifting force, which is determined by the force-bearing area of ​​the air guide groove and the airflow velocity. After the slider floats, a drive device drives the sliding seat to move. The sliding seat moves easily without friction with the base plate, guided by two sliding strips. When the sliding seat delivers the product to the bottom of the press, the inflation of the slide block stops, the sliding seat rests on the base plate, and the press presses the node into the rod or removes the node from the rod. The sliding seat and the base plate bear the pressure.

[0021] The present invention also provides a metal-rubber component joint pressing system and a metal-rubber component joint unloading system, both of which utilize the aforementioned air-suspended sliding platform to transport the workpiece. By changing the tooling, the system becomes versatile. Attached Figure Description

[0032] 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

[0033] Analysis of the background technology shows that existing technologies use presses to replace manual labor in removing nodes from rods or pressing new nodes into rods, reducing labor intensity and improving production efficiency. However, analysis reveals that the pressure applied by the press can reach tens of tons. This pressure acts on the conveyor line, which cannot withstand such pressure. Therefore, existing technologies suffer from insufficient load-bearing capacity. This application primarily addresses the problem of the conveyor line's inability to withstand such high pressure by providing an air-suspended sliding platform. The specific structure is as follows:

[0034] An air-suspended sliding platform for press-fitting rubber nodes, such as Figure 1 and Figure 2 As shown, the system includes a suspension assembly, an inflation device, and a guide seat 2. The suspension assembly includes a base plate 11, slide bars 12 mounted on the base plate 11, a sliding seat 13, and a drive device 14. The slide bars 12 are fixed in pairs on the base plate 11, and the sliding seat 13 is located between the two slide bars 12. The drive device 14 drives the sliding seat 13 to move, and the two slide bars 12 guide the movement of the sliding seat 13. Figure 2 As shown, the sliding seat 13 has an air inlet 15, and the bottom of the sliding seat 13 that contacts the base plate 11 has an air guide groove, connecting the air inlet 15 to an inflation device. Inflating the air inlet 15 with the inflation device allows the sliding seat 13 to detach from the base plate 11 and float. The guide seat 2 is fixed to the sliding seat 13, and the retraction and installation fixtures are mounted on the guide seat 2. In this embodiment, the air inlet 15 is located at the center of the upper surface of the sliding seat 2.

[0035] like Figure 3 As shown, the air guide groove at the bottom of the sliding seat 13 is located in the middle of the bottom of the sliding seat 13, so that the bottom is evenly stressed when inflated. The air guide groove is composed of multiple circular grooves 16a and straight grooves 16b connecting two circular grooves 16a. In this embodiment, there are 3 circular grooves 16a, and the circular groove 16a located in the middle position is connected to the air hole 15.

[0036] This invention utilizes a structure of sliding seat 13 and base plate 11. This structure is chosen because existing technologies cannot withstand pressures of tens of tons during pressing and assembly of nodes. In this invention, both the sliding seat 13 and base plate 11 are made of steel. The product is placed on a tooling fixture, which is mounted on a guide seat 2. During stamping, the steel structure of the sliding seat 13 and base plate 11 can withstand pressures of tens of tons. However, the movement of the steel sliding seat 13 on the steel base plate results in excessive friction. To address this problem, this invention designs an air-suspended sliding platform.

[0037] In this embodiment, the air-suspended sliding platform is in use by inflating the air holes 15 of the sliding seat 13 through an inflation device. The air in the inflation holes 15 enters the central circular groove 16a, then passes through the straight grooves 16b into the two side circular grooves 16a. The air continuously flows and inflates in the air guide grooves at the bottom of the sliding seat 13 until an equilibrium is reached, causing the sliding seat 13 to detach from the base plate 11 and float. This invention does not require the sliding seat 13 to float too high; for example, 0.1 mm is sufficient. After the sliding seat 13 floats, the drive device 14 only needs to use a small force to move the sliding seat 13 below the press.

[0038] The magnitude of the lifting force exerted by the air on the air guide groove is equal to the product of the area of ​​the air guide groove and the atmospheric pressure. The magnitude of the lifting force of the sliding seat 13 is determined by the area of ​​the force-bearing area.

[0039] like Figure 1 As shown, the drive device 14 includes a motor 14a, a reducer 14b, a transmission component, a timing belt 14c, and a connecting seat 14d, which are connected in sequence. The transmission component includes a long shaft 14e, with a timing belt 14c connected to each end of the long shaft 14e. The two timing belts 14c are located on both sides of the sliding seat 13. A connecting seat 14d is fixed to each timing belt 14c, and the connecting seat 14d is fixed to the sliding seat 13. The power of the motor 14a drives the sliding seat 13 to move via the transmission component, timing belt 14c, and connecting seat 14d. This application preferably uses a timing belt to drive the sliding seat 13 because the sliding seat 13 becomes lighter after being air-suspended, so a timing belt is sufficient and there is no need to use a chain or other similar device.

[0040] like Figure 1 As shown, the motor 14a and the reducer 14b are mounted on one end of the base plate 11. The transmission component includes a long shaft 14e, and pulleys 14f and 14g connected to the output end of the reducer 14b. Pulley 14g is fixed to the long shaft 14e, and pulleys 14f and 14g are connected by a synchronous belt 14h. Both ends of the long shaft 14e are also movably connected to the base plate 11 via bearings, and pulleys 14i adapted to synchronous belt 14c are fixed to both ends of the long shaft 14e.

[0041] This application also includes a guide anti-fooling seat 3 and a drive device 4 mounted on the sliding seat 13, such as Figure 1 As shown, the guide anti-fool seat 3 includes two halves, which are located on both sides of the guide seat 2. The shape of the guide anti-fool seat 3 facing the tooling is adapted to the shape of the tooling. During stamping, the drive device 2 4 drives the two halves of the guide anti-fool seat 3 to hold the tooling tightly. After the pressing is completed, when the robot arm removes the product from the tooling, the robot arm will not lift the tooling. In this embodiment, the drive device 2 4 is a cylinder, and each halves of the guide anti-fool seat 3 is driven by two cylinders. This is because the greater the force of the cylinder, the larger the cylinder diameter, and the wider the sliding seat 13 required during installation. Therefore, in this application, each halves of the guide anti-fool seat 3 is driven by two cylinders, which facilitates cylinder installation and avoids increasing the width of the sliding seat 13.

[0042] like Figure 1 As shown, the sliding seat 13 includes a slider 13a and a slider adapter plate 13b fixed to each other. The slider 13a is located below and contacts the base plate 11, while the slider adapter plate 13b is located above and sits on top of the slider strip 12. The width of the slider adapter plate 13b is greater than the distance between the two slider strips 12 to facilitate connection with the connecting seat 14d. The air guide groove is located on the slider 13a, the guide seat 2 is mounted on the slider adapter plate 13, the connecting seat 14d is connected to the slider adapter plate 13, and the guide anti-fooling seat 3 and the driving device 2 4 are mounted on the slider adapter plate 13.

[0043] like Figure 1 As shown, the bottom surface of the guide anti-fool seat 3 is also provided with a guide component 5. The guide component 5 includes a guide sleeve 19a and a slide rail 19b. The guide sleeve 19a is fixed to the bottom surface of the guide anti-fool seat 3, and the slide rail 19b is fixed to the slider adapter plate 13. When the driving device 4 drives the guide anti-fool seat 3 to move towards the tooling, the guide component 5 guides the movement of the guide anti-fool seat 3. As shown in the figure, the bottom surface of the guide anti-fool seat 3 is provided with two sets of guide components 5.

[0044] Metal rubber parts come in various shapes, such as rods. To ensure the balance of the workpiece during stamping, this application also includes a support seat 6 mounted on the slider adapter plate. The support seat 6 is located on one side of the guide seat 2. The support seat 6 and the tooling mounted on the guide seat 2 jointly support the workpiece. During stamping, one end to be stamped is located on the tooling, and the other end is placed on the support seat 6.

[0045] An oil-proof cover 7 is also installed on the guide anti-fool seat 3, which extends out from the guide anti-fool seat 3 and covers the top of the drive device 4.

[0046] The air-suspended sliding platform for rubber node stamping and pressing described in this application is used in an automated system. A robotic arm places the tooling on the guide seat 2, and the workpiece is also placed by the robotic arm. After the node is removed or installed, the robotic arm needs to remove the tooling. To prevent interference between the support seat and the tooling at this time, this application provides a retractable support seat 6. Specifically, the support seat 6 includes a bracket 61, a drive device 62, and a rotating shaft 63. A roller 64 is mounted on the top of the bracket 61, and the bottom of the bracket 61 is movably connected to the rotating shaft 63, which is driven to rotate by the drive device 62. The drive device 62 is a rotary cylinder, and a rotary cylinder is provided on each side of the bracket 61 (i.e., on both sides of the rotating shaft). When the robotic arm places the product, the drive device 62 drives the bracket 61 to rotate and rise, making the support seat 6 perpendicular to the slider adapter plate 13b. When the robotic arm removes the tooling, the drive device 62 drives the bracket 61 to rotate and lower.

[0047] As shown in the figure, a buffer pad 8 is also provided on the side of the support base 6 away from the guide seat 2. The buffer pad 8 is installed on the slider transition plate 13b. When the drive device 3 62 drives the support base 6 to rotate and lie down, it lies down to the side away from the guide seat. Example 2

[0048] This embodiment provides a metal-rubber component joint press-fitting system, such as... Figure 4 and Figure 5 As shown, it includes a base 100, a conveying device 200, a press 300, and a mounting fixture. The conveying device 200 is the air-suspended sliding platform for pressing and mounting rubber nodes as described in Embodiment 1. The conveying device 200 and the press 300 are both mounted on the base 100. The mounting fixture is mounted on the conveying device 200. The workpiece is placed on the mounting fixture, and the conveying device 200 moves the workpiece below the press 300.

[0049] like Figure 6 As shown, the press 300 includes a support frame, a drive device 320 mounted on the support frame, and a pressure head 330 connected to the output end of the drive device 320. The drive device 320 drives the pressure head 330 downward. The support frame includes a drive device mounting plate 311, a guide plate 312, a column 313, and a column mounting plate 314. The column mounting plate 314 is mounted on the base 100. The column 313 is supported between the drive device mounting plate 311 and the column mounting plate 314. The drive device 320 is mounted on the drive device mounting plate 311. The guide plate 312 is also connected to the output end of the drive device 320. The guide plate 311 uses the column 313 as a guide rod, and the drive device 320 drives the guide plate 312 to slide along the column 313.

[0050] As shown in the figure, the metal-rubber component node pressing system also includes an oiling robot 400, which is mounted on the base plate 11 and located on the outer side of one end of the air-suspended sliding platform. As shown in the figure, the guide seat 2 is located between the oiling robot 400 and the support seat 6.

[0051] like Figure 4 As shown, it also includes a protective cover assembly 500, which is mounted on the base 100. The oiling robot 400, guide seat 2, and support seat 6 are arranged in sequence. During stamping, the protective cover assembly 500 encloses the oiling robot 400, guide seat 2, and press 300. The enclosure has an opening on one side in the direction of movement of the conveying device, through which the support seat 6 protrudes. The protective cover assembly 500 consists of multiple door panels, each equipped with a lock. The protective cover assembly 500 prevents safety accidents during stamping. One side of the protective cover assembly 500 has an opening, through which the robot arm reaches to remove the product and assembly fixtures after the product is pressed.

[0052] In use, the support base 6 is raised, and the robot arm installs the fixed fixture from the pressing node fixture onto the guide seat 2, with one end of the fixed fixture resting on the support base 6. The robot arm then installs the movable fixture onto the fixed fixture, and then places the rod body onto the movable fixture. The robot arm places the node at the position where the node needs to be pressed onto the rod body. The inflation device inflates the slider 13a, causing the slider 13 to float. The drive device 14 drives the slider 13 closer to the position of the oiling robot arm 400, and the oiling robot arm 400 applies oil to the node. The drive device 14 drives the slider 13 to the position of the press 300. The node to be pressed and the rod body are located directly below the press 300. At this time, the inflation device stops inflating, the slider 13 falls onto the base plate 11, and the press 300 starts pressing the node into the inner hole of the rod body. The robotic arm removes the pressed product and then removes the pressing fixture. Before or during fixture removal, the drive unit 62 drives the support 61 to rotate and lie flat. In this embodiment, during pressing, the sliding seat 13 and the base plate 11 jointly bear the pressure of the press 300. Both the sliding seat 13 and the base plate 11 are made of steel and have a large load-bearing capacity. This solves the problem that existing pressing devices cannot withstand tens of tons of pressure due to insufficient rigidity. Example 3
