Description

Technical Field

[0001] This invention belongs to the field of bearing press-fitting technology, specifically an automated integrated wheelset bearing press-fitting equipment. Background Technology

[0002] Railways are an important mode of transportation in my country. Railway vehicles often have multiple wheelsets rotating at the bottom. The wheelsets can fit in close to the railway track to ensure the safety of the railway vehicles during high-speed operation. The wheelset bearings are an important component of railway vehicles, which can support the wheels and bear and transmit the load from the track.

[0003] A patent application with publication number CN108127369B discloses an intelligent wheelset pressing and automated warehouse production line for railway vehicles. The entire production line consists of an intelligent detection section, a wheelset pressing section, a bearing pressing machine, a wheelset transition device, and a wheelset storage section. The process of the entire production line, from left to right, is as follows: the axle completes parameter detection in the intelligent detection section; the axle is transported to the wheelset pressing section and assembled with the wheel to form a wheelset; the wheelset is sent to the bearing pressing machine to press the bearing onto the wheelset; after assembly, the wheelset transition device sends the finished wheelset to the wheelset storage section for shelving and storage. The entire production process, from detection, assembly, transportation, and storage, is completed automatically.

[0004] The installation of bearings on existing wheelsets often relies on a hydraulic system to push them. When dealing with wheelsets of different models, the different sizes of the wheelsets cause positional deviations between the wheelsets and the rails, which in turn leads to deviations during bearing installation. Furthermore, after multiple wheelsets have been moved, impurities adhering to the wheelsets remain on the rails, causing positional deviations in subsequent wheelsets during bearing installation due to the presence of these impurities, thus affecting the bearing installation.

[0005] Therefore, the present invention provides an automated integrated wheelset bearing press-fitting device. Summary of the Invention

[0039] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0040] like Figures 1 to 3 As shown in the figure, an automated integrated wheelset bearing press-fitting device according to an embodiment of the present invention includes:

[0041] Positioning station 1,

[0042] Track 11, a pair of tracks 11 are installed in the middle of the positioning platform 1;

[0043] Positioning chambers 12 are a pair symmetrically fixed to both sides of the positioning platform 1;

[0044] Hydraulic push rod 13 is fixedly connected to the side wall of the positioning chamber 12;

[0045] Wheelset 14, which rolls between a pair of said tracks 11;

[0046] The first slide 15 is located in the middle of the track 11;

[0047] Electric actuator 16 is fixedly connected to the bottom of slide groove 15.

[0048] Positioning plates 17, there are multiple sets of positioning plates 17, and they slide inside the first slide groove 15;

[0049] There are multiple sets of No. 1 rotating shafts 18, and each set is rotatably connected between each pair of positioning plates 17.

[0050] Push plates 19, multiple sets of push plates 19, with the top and bottom of each set of push plates 19 respectively hinged between the positioning plate 17 and the first electric push rod 16; during the installation of the bearings on both sides of the wheelset 14, the positioning chambers 12 installed on both sides of the positioning platform 1 can drive the bearings into the sides of the wheelset 14 for installation through the pushing effect of the hydraulic push rod 13. At the same time, as the wheelset 14 moves, the first sliding groove 15 in the middle of the track 11 can allow the first electric push rod 16 to be positioned. At this time, the pushing of the first electric push rod 16 can drive the positioning plate 17 to fit against the side wall of the wheelset 14. The presence of shaft 18 can drive the positioning plate 17 to rotate. At this time, different models of wheelset 14 can cause different displacement distances of the pushing effect of the first electric push rod 16. Through the first sliding groove 15 opened in the middle of the track 11, the wheelset 14 can present the same slope when moving. At the same time, when facing wheelset 14 of different models and sizes, the pushing effect of the first electric push rod 16 causes the positioning plate 17 to rotate along the first rotating shaft 18, so that the positioning plate 17 wraps around the side wall of the wheelset 14, thereby improving the adaptability to different models of wheelset 14 and improving the stability of the wheelset 14 during bearing installation.

[0051] like Figures 2 to 4As shown, each of the multiple sets of positioning plates 17 has a second sliding groove 2 on its side wall near the first rotating shaft 18; a first rubber plate 21 is fixed between the first rotating shaft 18 and the second sliding groove 2; multiple sets of third sliding grooves 22 are opened on the top surface of the positioning plates 17; the third sliding grooves 22 are connected to the positioning chamber 12; multiple sets of second rubber plates 23 are fixed to the top surface of the second sliding groove 2; the second rubber plates 23 slide inside the third sliding groove 22; during the bearing installation process of the wheelset 14, the first electric push rod 16 pushes the positioning plates 17. At this time, as the positioning plates 17 and the wheelset 14 approach and fit together, the multiple sets of positioning plates 17 can rotate along the first rotating shaft 18. The change in angle between each pair of positioning plates 17 can cause the second slide groove 2 to produce a pulling effect. At this time, with the deformation of the second slide groove 2, the second rubber plate 23 can move inside the third slide groove 22 until it contacts the side wall of the wheel set 14. Through the second slide groove 2 opened on the side wall of the positioning plate 17, the position of the wheel set 14 can be restricted when the positioning plate 17 and the side wall of the wheel set 14 are attached. At this time, as the angle of the positioning plate 17 changes, the second rubber plate 23 will move inside the third slide groove 22 until it is attached to the side wall of the wheel set 14, increasing the friction with the wheel set 14, increasing the positioning effect of the positioning plate 17 on the wheel set 14, and increasing stability.

[0052] like Figures 2 to 7 As shown, the track 11 has four sliding grooves 3 on both side walls; a cleaning block 31 is slidably connected to the top surface of the track 11; a sliding plate 34 is provided on both sides of the cleaning block 31; the bottom end of the sliding plate 34 slides inside the four sliding grooves 3; a connecting plate 32 is rotatably connected to the side wall of the cleaning block 31; a support plate 33 is rotatably connected to the side of the connecting plate 32 away from the cleaning block 31; the curvature of the support plate 33 is the same as that of the wheelset 14; during the bearing installation of the wheelset 14, the support plate 33 can fit against the side wall of the wheelset 14, and the wheelset 14 can be installed in a manner that allows for proper bearing installation. During the movement, the wheelset 14 can push the support plate 33 to move, causing the support plate 33 to push the cleaning block 31 to move on the top surface of the track 11. Utilizing the triangular setting of the cleaning block 31 itself, it scrapes away impurities on the top surface of the track 11. Through the cleaning block 31 installed on the top surface of the track 11, it can drive the cleaning block 31 to move during the movement of the wheelset 14, scraping away impurities on the top surface of the track 11, reducing the accumulation of impurities that cause unevenness on the surface of the track 11, which in turn affects the angular deviation of the wheelset 14 and the installation of the bearings of the wheelset 14.

[0053] like Figures 5 to 6As shown, a guide plate 4 is fixedly connected to the side wall of the cleaning block 31; a receiving plate 41 is fixedly connected to the middle of the sliding plate 34; the side wall of the receiving plate 41 is in contact with the side wall of the track 11; a blocking plate 42 is fixedly connected to the top side wall of the receiving plate 41 away from the track 11; a net bag 43 is fixedly connected to the middle of the receiving plate 41; during the movement of the cleaning block 31, as the cleaning block 31 contacts the top surface of the track 11, impurities present on the top of the track 11 can be scraped off. At this time, when the impurities move along the slope of the cleaning block 31, the side wall of the cleaning block 31 is equipped with... The first guide plate 4 can use its own curvature to allow impurities to move to both sides. At this time, the impurities can enter the net bag 43 installed in the middle of the receiving plate 41 for storage. With the blocking effect of the barrier plate 42, the impurities are collected. Through the first guide plate 4 installed on the side wall of the cleaning block 31, the curvature of the first guide plate 4 can be used to restrict the movement of impurities, allowing the impurities to move smoothly to both sides. This allows the impurities to be smoothly collected on the barrier plate 42 installed in the middle of the receiving plate 41, which is convenient for subsequent workers to process them in one go.

[0054] like Figures 5 to 6 As shown, a second connecting plate 51 is fixedly connected to the side wall of the sliding plate 34; a second guide plate 5 is provided on the side wall of the second connecting plate 51; a fifth sliding groove 53 is provided on both the upper and lower surfaces of the second connecting plate 51; one end of a support rod 52 is slidably connected to the inside of the fifth sliding groove 53 via a spring; the other end of the support rod 52 is hinged to the side wall of the second guide plate 5; during the process of the sliding plate 34 moving to remove impurities on the surface of the track 11, as the impurities move, the second connecting plate 51 installed on the side wall of the sliding plate 34 can move the second guide plate 5. The guide plate 5 provides support, allowing impurities to come into contact with it. The arc created by the support rod 52 guides the movement of the impurities, allowing them to smoothly enter the net bag 43 for storage. Through the blocking effect of the guide plate 5, combined with the bending arc, the moving impurities can be guided, allowing them to move smoothly downwards into the net bag 43 for storage. This reduces the movement of impurities scooped up by the cleaning block 31 backwards during movement, thus improving the collection effect and reducing the scattering of impurities.

[0055] like Figures 5 to 7As shown, positioning posts 6 are fixedly connected to both side walls of the cleaning block 31; the sliding plate 34 is slidably connected inside the positioning posts 6; a positioning pin 61 is fixedly connected to the middle of the positioning post 6; a pressing post 62 is sleeved on the outside of the positioning pin 61; the pressing post 62 and the positioning pin 61 are connected by a spring; multiple sets of pins 63 are slidably connected to the outer side wall of the positioning post 6; the bottom of the pin 63 and the pressing post 62 are connected by a rope; multiple sets of No. 6 sliding grooves 64 are opened inside the sliding plate 34 at the position of the pins 63; during the installation of the cleaning block 31, the worker can use the positioning posts 6... The presence of the pressing column 62, in conjunction with the pressing column 62, allows for the installation of the sliding plate 34. During installation, pressing the pressing column 62 causes it to move on the positioning pin 61, which in turn pulls the rope, causing the pin 63 to retract into the positioning column 6. This allows the sliding plate 34 to detach from and be installed on the positioning column 6. By pressing the pressing column 62, the worker can move the pin 63, causing it to disengage from the sixth slide groove 64. This facilitates the overall disassembly and installation of the sliding plate 34, reducing the tedious disassembly operations during bolt installation and minimizing bolt loosening caused by vibration.

[0056] like Figures 6 to 7 As shown, a pair of rollers 73 are rotatably connected to the bottom of the cleaning block 31; a first magnet 7 is installed inside each of the rollers 73; a second magnet 71 is fixedly connected to the bottom of the second guide plate 5; a second rotating shaft 72 is rotatably connected to the end of the second connecting plate 51; the middle of the second guide plate 5 is fixedly connected to the side wall of the second rotating shaft 72; the first magnet 7 and the second magnet 71 are magnetically attracted to each other; during the movement of the cleaning block 31, with the rotation effect of the rollers 73, the first magnet 7 can be continuously moved towards the position of the second magnet 71. At this time, as the distance between the first magnet 7 and the second magnet 71 shortens, the first magnet 7 and the second magnet 71... The magnetic attraction between magnets 71 can drive guide plate 5 to rotate along shaft 72, creating a swinging effect. When the debris scooped up by the cleaning block 31 comes into contact with guide plate 5 along the arc of guide plate 4, the swinging of guide plate 5 reduces the impact. By utilizing the magnetic attraction between magnets 71 and 72, guide plate 5 can be rotated and swung during the movement of cleaning block 31, thus buffering the splashed debris and allowing it to fall smoothly into net bag 43, reducing the wear and tear on guide plate 5 under impact.

[0057] like Figures 4 to 6As shown, each of the multiple sets of positioning plates 17 has a seventh sliding groove 81 on its top; a third magnet 8 is slidably connected inside the seventh sliding groove 81 via a spring rod; each of the pair of rollers 73 has an eighth sliding groove 82 on its side wall; a first magnet 7 slides inside the eighth sliding groove 82 via a spring rod; the first magnet 7 and the third magnet 8 are magnetically attracted to each other; during the movement of the cleaning block 31, as the rollers 73 rotate, the first magnet 7 will move during the rotation. At this time, as the rollers 73 move on the multiple sets of positioning plates 17, the first magnet 7 will interact with the multiple sets of third magnets. The magnetic attraction between the iron blocks 8 causes the third magnet 8 and the first magnet 7 to move inside the seventh slide 81 and the eighth slide 82, respectively. Then, under the elastic force of the spring rod, they reset and collide. Through the continuous movement of the cleaning block 31, when the cleaning block 31 passes above the multiple sets of positioning plates 17, the magnetic attraction between the third magnet 8 and the first magnet 7 causes the first magnet 7 and the third magnet 8 to move and collide, causing vibration. This loosens the impurities on the track 11 and the positioning plates 17, causing them to fall off and reducing the impact on the wheelset 14.

[0058] like Figures 1 to 2 As shown, a first positioning ring 9 is installed in the middle of the wheelset 14; a second positioning ring 91 is hinged to the side wall of the first positioning ring 9 via a torsion spring; both side walls of the second positioning ring 91 are hinged to limit plates 92 via torsion springs; a ninth sliding groove 93 is formed on both side walls of the first positioning ring 9 at positions corresponding to the limit plates 92; a traction device is connected to the side wall of the first positioning ring 9 via a rope; during the process of the traction device moving the wheelset 14, the first positioning ring 9 and the second positioning ring 91 can rotate to form a circle that wraps around the wheelset 14, through... The torsion effect of the torsion spring on the limiting plate 92 allows the limiting plate 92 to enter the ninth slide groove 93 to fix the first positioning ring 9 and the second positioning ring 91, maintaining the wrapping of the wheelset 14. The wrapping effect of the first positioning ring 9 and the second positioning ring 91 on the wheelset 14 can reduce the need for traditional binding with iron cables, reducing the complexity of the operation. At the same time, the rotation between the second positioning ring 91 and the first positioning ring 9 can change the angle between the second positioning ring 91 and the first positioning ring 9 according to the size of the wheelset 14, making it easier for workers to install.

[0059] like Figure 1As shown, a pair of clamping plates 101 are slidably connected to the middle of the positioning platform 1; a second electric actuator 102 is fixedly connected to the top center of the positioning platform 1; the output end of the second electric actuator 102 is in contact with the side wall of the clamping plate 101; after long-term use of the track 11, the surface of the track 11 will inevitably wear. At this time, the pushing effect of the second electric actuator 102 can drive the clamping plate 101 to move, so that it is out of contact with the track 11, allowing the track 11 to move and making it easier for the staff to replace it. The pushing effect of the second electric actuator 102 can facilitate the disassembly and installation of the track 11 by the staff, reducing the cumbersome disassembly operation when the track 11 is damaged and needs to be replaced.

[0060] During the operation, when the bearings on both sides of the wheelset 14 are installed, the positioning chambers 12 installed on both sides of the positioning platform 1 can drive the bearings into the sides of the wheelset 14 for installation through the pushing effect of the hydraulic push rods 13. At the same time, as the wheelset 14 moves, the first sliding groove 15 in the middle of the track 11 can place the first electric push rod 16. At this time, the pushing of the first electric push rod 16 can drive the positioning plate 17 to fit against the side wall of the wheelset 14. Meanwhile, the presence of the first rotating shaft 18 can drive the positioning plate 17 to rotate. At this time, different models of the wheelset 14 can be adjusted to allow the first... The pushing effect of the electric actuator 16 produces different displacement distances. During the bearing installation process of the wheelset 14, the first electric actuator 16 pushes the positioning plate 17. At this time, as the positioning plate 17 and the wheelset 14 approach and fit together, multiple sets of positioning plates 17 can rotate along the first rotating shaft 18. At this time, as the angle between each pair of positioning plates 17 changes, the second slide groove 2 can produce a pulling effect. At this time, as the second slide groove 2 deforms, the second rubber plate 23 can move inside the third slide groove 22 until it contacts the side wall of the wheelset 14.

[0061] During the bearing installation process of wheelset 14, the support plate 33 can fit against the side wall of wheelset 14. As wheelset 14 moves, it pushes the support plate 33, causing the support plate 33 to push the cleaning block 31 to move on the top surface of track 11. Utilizing the triangular design of the cleaning block 31, it scrapes away impurities on the top surface of track 11. During the movement of the cleaning block 31, as it contacts the top surface of track 11, impurities on the top of track 11 are scraped away. At this time, the impurities move along... When the cleaning block 31 moves along the slope, the first guide plate 4 installed on the side wall of the cleaning block 31 can use its own curvature to allow impurities to move to both sides. At this time, the impurities can enter the net bag 43 installed in the middle of the receiving plate 41 for storage. With the blocking effect of the barrier plate 42, the impurities are collected. During the process of the sliding plate 34 moving to remove impurities on the surface of the track 11, as the impurities move, the second connecting plate 51 installed on the side wall of the sliding plate 34 can support the second guide plate 5, so that the impurities on the second guide plate 5 can be removed. The contact point utilizes the arc created by the support rod 52 to guide the movement of impurities, allowing them to smoothly enter the net bag 43 for storage. During the installation of the cleaning block 31, the worker can use the positioning post 6 in conjunction with the pressing post 62 to install the sliding plate 34. During installation, pressing the pressing post 62 moves it on the positioning pin 61, causing the pressing post 62 to pull the rope, causing the pin 63 to retract into the positioning post 6, thus driving the sliding plate 34 and the positioning post 6 into place. During the disassembly and assembly of the cleaning block 31, as the roller 73 rotates, the first magnet 7 can continuously move towards the position of the second magnet 71. At this time, as the distance between the first magnet 7 and the second magnet 71 shortens, the magnetic attraction between the first magnet 7 and the second magnet 71 can drive the second guide plate 5 to rotate along the second rotating shaft 72, producing a swinging effect. When the impurities scooped up by the cleaning block 31 come into contact with the second guide plate 5 along the arc of the first guide plate 4 during the movement, the swinging of the second guide plate 5 reduces the buffering effect.

[0062] During the movement of the cleaning block 31, as the roller 73 rotates, the first magnet 7 moves during rotation. At this time, as the roller 73 moves on multiple positioning plates 17, the first magnet 7 and multiple sets of third magnets 8 will generate a magnetic attraction effect, causing the third magnet 8 and the first magnet 7 to move inside the seventh slide groove 81 and the eighth slide groove 82 respectively. Subsequently, under the elastic force of the spring rod, they reset and collide. During the movement of the traction device driving the wheelset 14, the first positioning ring 9 and the second positioning ring 91 can... The rotating mechanism forms a circular shape that wraps around the wheel pair 14. Through the torsion effect of the torsion spring on the limiting plate 92, the limiting plate 92 enters the ninth slide groove 93 to fix the first positioning ring 9 and the second positioning ring 91, maintaining the wrapping of the wheel pair 14. After long-term use of the track 11, the surface of the track 11 will inevitably wear. At this time, the pushing effect of the second electric push rod 102 can drive the clamping plate 101 to move, so that it is out of contact with the track 11, allowing the track 11 to move and making it easy for the staff to replace it.
