Description

Technical Field

[0001] This utility model relates to the technical field of railway vehicle manufacturing and maintenance equipment, specifically a bogie frame tilting device with positioning function. Background Technology

[0002] As is well known, with the rapid development of railway transportation, the manufacturing and maintenance of railway vehicles have put forward higher requirements for the precision, efficiency and reliability of equipment. As one of the core components of railway vehicles, the bogie frame needs to be flipped multiple times during its production and maintenance to complete welding, testing and assembly processes.

[0003] Traditional bogie frame flipping equipment has the following problems: Traditional equipment usually relies on manual adjustment of the frame position, which is prone to positioning deviation due to human error. This deviation may cause clamping failure or frame instability during flipping, which seriously affects the quality and safety of subsequent processes. During the flipping process, due to the lack of an effective self-locking mechanism or dynamic monitoring system, the frame may shake or loosen, increasing the operational risk. In particular, the stability problem is more prominent in the flipping of large-size or heavy-duty frames. Utility Model Content

Each of the two sets of fixed seats has a turntable installed via the tilting device. The clamping device is installed on the side wall of the turntable. The positioning device is installed on the bottom wall of the support frame. The control system is installed at one end of the support frame. The positioning device includes a laser rangefinder and a visual recognition system. The visual recognition system is installed on the bottom wall of the frame. Two sets of laser rangefinders are symmetrically installed on the bottom wall of the support frame around the central axis of the visual recognition system. The clamping device includes a rectangular slot, a bidirectional screw, a slider, a positioning plate, a positioning pin, and a first motor. The rectangular slot is opened on the side wall of each of the two sets of turntables. The bidirectional screw is rotatably installed in the rectangular slot. The first motor is installed through the rectangular slot at one end of the bidirectional screw. The slider is installed at both the upper and lower ends of the bidirectional screw. Two sets of positioning plates are fixedly installed on the side wall of each slider. The positioning pin is installed on the corresponding end of each pair of positioning plates.

[0008] To achieve the flipping function, this utility model is improved by including a worm gear, a worm, a second motor, and a rotating shaft. The worm gear is rotatably installed inside the fixed base, and the top end of the worm gear is meshed with the worm. One end of the worm passes through the side wall of the fixed base and is equipped with the second motor. The rotating shaft is fixedly installed in the middle of the worm gear, and the end of the rotating shaft away from the fixed base passes through the side wall of the fixed base and is fixedly connected to the turntable.

[0009] To achieve height adjustment, this utility model is improved by including a threaded rod, a moving block, and a third motor in the height adjustment device. Grooves are provided on the inner sidewalls of both ends of the support frame. The threaded rod is rotatably installed in the grooves. The third motor is installed through the top of the threaded rod and threaded onto the top wall of the support frame. The moving block is threaded onto the threaded rod.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a bogie frame tilting device with positioning function, which has the following advantages:

[0017] This bogie frame tilting device with positioning function achieves millimeter-level (±1mm) positioning accuracy through a positioning device that combines a vision recognition system and a laser rangefinder. This ensures that the bogie frame is in the correct position before tilting, avoiding clamping failure or tilting instability caused by positional deviation. It improves the overall performance of the device and meets the high-precision requirements of railway vehicle manufacturing and maintenance. The vision recognition system detects the position of the frame in real time through a camera and transmits the deviation information to the control system. The laser rangefinder further assists in calibration, reducing the possibility of human error and ensuring the consistency and reliability of each operation.

[0018] This bogie frame tilting device with positioning function uses a clamping device and a tilting device. The first motor drives the bidirectional screw to rotate, which moves the slider along the rectangular groove. This ensures that the positioning plate and positioning pin can accurately approach the bogie frame. The positioning pin cooperates with the corresponding hole on the frame to firmly fix the frame on the turntable, ensuring stability during operation. The worm gear transmission structure has self-locking properties, which can effectively prevent the turntable from rotating back when the tilting stops, further improving stability.

[0019] This bogie frame tilting device with positioning function has a height adjustment device and a position adjustment device. The height adjustment device realizes the vertical movement of the fixed seat through a threaded rod and a moving block, and the position adjustment device realizes the horizontal movement of the fixed seat through a cylinder. It can dynamically adjust the height and position of the clamping device according to the specific size of the bogie frame, thus expanding the application range of the equipment and making it suitable for bogie frames of various specifications.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4A bogie frame tilting device with positioning function includes a support frame 1, a height adjustment device, a position adjustment device, a clamping device, a tilting device, a positioning device, and a control system. Fixed seats 2 are installed inside the support frame 1 via two sets of the height adjustment devices and the position adjustment devices. Each set of fixed seats 2 is equipped with a turntable 3 via the tilting device. The clamping device is installed on the side wall of the turntable 3. The positioning device is installed on the bottom wall of the support frame 1. The control system is installed at one end of the support frame 1. The positioning device includes a laser rangefinder 4 and a visual recognition system 5. The visual recognition system 5 is installed on the bottom wall of the frame 1. Two sets of laser rangefinders 4 are symmetrically installed on the bottom wall of the supporting frame 1 around the central axis of the visual recognition system 5. The clamping device includes a rectangular slot 6, a bidirectional screw 7, a slider 8, a positioning plate 9, a positioning pin 10, and a first motor 11. The rectangular slot 6 is opened on one side wall of each of the two sets of turntables 3. The bidirectional screw 7 is rotatably installed in the rectangular slot 6. One end of the bidirectional screw 7 passes through the rectangular slot 6 and is installed with the first motor 11. The slider 8 is installed at both the upper and lower ends of the bidirectional screw 7. The side wall of the slider 8 Two sets of positioning plates 9 are fixedly installed on each of the two sets of positioning plates 9, and positioning pins 10 are installed on one end of each pair of positioning plates 9. In this embodiment, the support frame 1 is fixed on the ground or other foundation platform to ensure its stability. The control system is started, and the visual recognition system 5 starts working. The visual recognition system 5, i.e., the camera, performs a preliminary detection of the position of the frame. The beam emitted by the laser rangefinder 4 is used to assist in calibration and further accurately locate the position of the frame, ensuring that the deviation of the frame in the horizontal and vertical directions is controlled within ±1mm. By adjusting the height adjustment device and the position adjustment device, the two sets of fixed seats 2 are positioned in a suitable position. Positioning the frame facilitates the next clamping step. The first motor 11 of the clamping device is then activated, driving the bidirectional screw 7 to rotate. The bidirectional screw 7 drives the slider 8 to move along the rectangular groove 6, causing the positioning plate 9 and positioning pin 10 to approach the steering frame from both ends. The positioning pin 10 inserts into the corresponding holes on the frame, firmly fixing the frame to the turntable 3. The flipping device is then activated, driving the turntable 3 to rotate around the rotation axis 15, achieving the flipping of the steering frame. The flipping angle is precisely controlled by the control system, supporting any angle adjustment within the range of 0° to 360°. During the flipping process, the positioning device continuously monitors the position of the frame to ensure its stability.

[0027] In practical use, to further realize the flipping function, in this embodiment, the flipping device includes a worm gear 12, a worm 13, a second motor 14, and a rotating shaft 15. The worm gear 12 is rotatably installed inside the fixed base 2. The top end of the worm gear 12 is meshed with the worm 13. One end of the worm 13 passes through the side wall of the fixed base 2 and is equipped with the second motor 14. The rotating shaft 15 is fixedly installed in the middle of the worm gear 12. The end of the rotating shaft 15 away from the fixed base 2 passes through the side wall of the fixed base 2 and is fixedly connected to the turntable 3. The control system issues... The command starts the second motor 14, which drives the worm 13 to rotate. Since the worm 13 and the worm wheel 12 are meshed, the rotation of the worm 13 is converted into the rotation of the worm wheel 12. The rotation of the worm wheel 12 is transmitted to the turntable 3 through the rotating shaft 15 fixed in the middle. The rotating shaft 15 drives the turntable 3 to rotate around the fixed seat 2, thereby realizing the flipping of the bogie frame. The control system precisely controls the running time and speed of the second motor 14 according to the preset flipping angle. When the set angle is reached, the control system stops the second motor 14 and completes the flipping operation.

[0028] In practical use, height adjustment is further achieved. In this embodiment, the height adjustment device includes a threaded rod 16, a moving block 17, and a third motor 18. Grooves are provided on the inner walls of both ends of the support frame 1. The threaded rod 16 is rotatably installed in the grooves. The top end of the threaded rod 16 penetrates the top wall of the support frame 1 and is fitted with the third motor 18. The moving block 17 is threaded onto the threaded rod 16. When the control system issues a command to start the third motor 18, the third motor 18 drives the threaded rod 16 to rotate. Due to the relationship between the threaded rod 16 and the moving block 17... The connection is threaded, and the rotation of the threaded rod 16 is converted into the linear motion of the moving block 17. The moving block 17 moves up and down along the threaded rod 16, driving the fixed seat 2 connected to it to rise and fall synchronously. The change in the height of the fixed seat 2 adjusts the position of the turntable 3, thereby realizing the height adjustment of the bogie frame. If it is necessary to restore the frame to the initial height or adjust it to other heights, the control system can run the third motor 18 in reverse, driving the threaded rod 16 to rotate in the opposite direction, thereby realizing the lowering or further raising of the fixed seat 2. The height adjustment function of the height adjustment device can provide space for the tilting of the bogie frame.

[0029] In actual use, the position adjustment of the two sets of clamping devices is further realized. In this embodiment, the position adjustment device includes a cylinder 19. The cylinder 19 is installed on the side wall of both sets of moving blocks 17. The output end of the two sets of cylinders 19 is fixedly connected to the end of the fixed seat 2 away from the turntable 3. The control system issues a command to start the cylinder 19. The piston rod of the cylinder 19 extends and retracts, driving the fixed seat 2 connected to it to move in the horizontal direction. The movement of the fixed seat 2 directly changes the position of the turntable 3, thereby realizing the adjustment of the distance between the two sets of clamping devices. This adjustment can be dynamically adapted according to the specific size and shape of the steering frame, and can be quickly removed after flipping.

[0030] In actual use, the movement of the slider 8 is further guided. In this embodiment, two sets of guide rods 20 are symmetrically installed in the rectangular groove 6 with the central axis of the bidirectional screw 7. The guide rods 20 are connected to the slider 8. The guide rods 20 provide stable support and constraint for the slider 8, preventing the slider 8 from deviating or shaking under the drive of the bidirectional screw 7, and ensuring that the slider 8 moves smoothly along the predetermined trajectory, thereby improving the working reliability of the clamping device.

[0031] Preferably, in this embodiment, the control system is an industrial computer 21. The industrial computer 21 is equipped with a high-performance processor and a large-capacity memory, which can quickly process complex control algorithms and real-time data, ensuring that the equipment can quickly respond to operation commands during operation and achieve high-precision positioning, flipping and adjustment functions.

[0032] Preferably, in this embodiment, the first motor 11, the second motor 14 and the third motor 18 are all servo motors. Servo motors have the ability to start, stop and accelerate quickly, with short response time, which improves the overall operating efficiency of the equipment and reduces operation waiting time. They are especially suitable for work scenarios that require frequent adjustments or rapid switching.

[0033] Preferably, in this embodiment, the support frame 1 has an inverted U-shaped design. The inverted U-shaped design creates an open space at the bottom of the support frame 1, providing sufficient operating space for the placement, clamping, and flipping of the steering frame. The inverted U-shaped design uses materials only in necessary parts, eliminating unnecessary excess parts.

[0034] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
