Description

Technical Field

[0001] This utility model relates to the field of train wheel maintenance technology, and in particular to a wheel fixing device for an automatic train wheel turning machine. Background Technology

[0002] During the maintenance of train wheels, a comprehensive inspection and maintenance of all parts of the wheel is required, including the rim, spokes, and hub. An automatic wheel-turning machine can flip the wheel at the required angle and direction.

[0003] However, in the existing technology, if the positioning is unstable during the fixing process, the wheelset may move or slip on the maintenance table unexpectedly, which will not only damage the maintenance equipment, but also pose a safety threat to the on-site personnel, and may even cause serious personal injury accidents. In addition, during the maintenance process, it is necessary to accurately measure key parameters such as wheel diameter, tread wear, wheel flange thickness, and roundness deviation to ensure that the wheelset meets the operating standards. However, if it is not fixed firmly, the wheelset may shift or shake during the measurement process, resulting in deviations in the measurement data, which in turn affects the maintenance quality and subsequent assembly accuracy. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where unstable positioning leads to the wheelset accidentally moving or slipping off the maintenance platform, which not only damages the maintenance equipment but also poses a safety threat to on-site personnel. Therefore, this invention proposes a wheel fixing device for an automatic train wheel turning machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wheel fixing device for an automatic train wheel turning machine, comprising a base plate and a positioning mechanism, wherein a control mechanism is installed on the top of the base plate and a positioning mechanism is installed on the side wall of the positioning mechanism;

[0006] The positioning mechanism includes a rotating frame, one end of which is rotatably connected to a linkage rod, and the other end of which is rotatably connected to a transmission rod. One end of the linkage rod is rotatably connected to a first positioning frame, and one end of the transmission rod is rotatably connected to a second positioning frame. A center rod is rotatably connected to the inner side of one end of the second positioning frame. One end of the center rod is fixedly connected to a mounting frame, and the outer surface of the center rod is rotatably connected to one end of the first positioning frame. Locking plates are fixedly connected to the inner sides of both the first and second positioning frames.

[0007] Preferably, a first cylinder is rotatably connected to one side of the bottom end of the mounting bracket, and the output end of the first cylinder is rotatably connected to the bottom end of the push rod.

[0008] Preferably, the control mechanism includes a rotating rod, the outer surface of which is fixedly connected to the bottom end of the mounting frame, and a gear is fixedly connected to one end of the rotating rod.

[0009] Preferably, a rack is meshed with the bottom of the gear, and a movable frame is fixedly connected to the outer wall of the rack.

[0010] Preferably, the bottom of the rack is slidably connected to a track, and the bottom of the track is fixedly connected to the base plate.

[0011] Preferably, a fixed plate is fixedly connected to one end of the mobile frame, and a second cylinder is installed on the top of the base plate.

[0012] Preferably, the output end of the second cylinder is fixedly connected to one end of the fixed plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the first cylinder drives the push rod, which causes the rotating frame to drive the linkage rod and the transmission rod to move synchronously, thereby achieving precise adjustment of the first positioning frame and the second positioning frame. The two positioning frames rotate in opposite directions around the central rod as the axis to ensure the wrap-around positioning of the wheel, making it stable and fixed. The cylinder provides a stable and controllable driving force, making the locking process efficient and reliable, reducing manual intervention. The synchronous linkage structure improves the stability of the fixation, shortens the adjustment time, improves the assembly efficiency, and enhances the safety and reliability of production.

[0015] 2. In this utility model, the fixed plate is driven by the second cylinder, which causes the moving frame to move the rack linearly along the track, ensuring stable meshing between the rack and the gear and avoiding deviation or jamming. The gear rotates under the action of the rack, further driving the rotating rod to rotate and causing the angle of the mounting frame to change, thereby accurately adjusting the angle of the positioning mechanism. This transmission method can accurately control the adjustment position of the wheel to achieve the optimal maintenance angle, improve the convenience of maintenance operations, and realize automated adjustment by using cylinder drive, reducing manual intervention, improving the efficiency and safety of maintenance work, and ensuring that the adjustment process is stable and reliable.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides a wheel fixing device for an automatic train wheel tilting machine, including a base plate 1 and a positioning mechanism 3. A control mechanism 2 is installed on the top of the base plate 1, and a positioning mechanism 3 is installed on the side wall of the positioning mechanism 3.

[0024] The positioning mechanism 3 includes a rotating frame 35, one end of which is rotatably connected to a linkage rod 33, and the other end of which is rotatably connected to a transmission rod 34. One end of the linkage rod 33 is rotatably connected to a first positioning frame 32, and one end of the transmission rod 34 is rotatably connected to a second positioning frame 37. One end of the second positioning frame 37 is rotatably connected to a center rod 38 on its inner side. One end of the center rod 38 is fixedly connected to the mounting frame 4, and the outer surface of the center rod 38 is rotatably connected to one end of the first positioning frame 32. Locking plates 36 are fixedly connected to the inner sides of both the first positioning frame 32 and the second positioning frame 37.

[0025] The first cylinder 5 is rotatably connected to one side of the bottom of the mounting bracket 4, and the output end of the first cylinder 5 is rotatably connected to the bottom of the push rod 31.

[0026] The specific setup and function of this embodiment will be described in detail below. When fixing the wheel, the first cylinder 5 can drive the push rod 31 to move, which will cause the rotating frame 35 to rotate together. During the rotation, the rotating frame 35 will drive the linkage rod 33 and the transmission rod 34 to move together. Therefore, the linkage rod 33 will control the first positioning frame 32 to move, while the transmission rod 34 will drive the second positioning frame 37 to move, so that the first positioning frame 32 and the second positioning frame 37 are adjusted in position synchronously.

[0027] During the movement, both the first positioning frame 32 and the second positioning frame 37 rotate around the central rod 38 in opposite directions, ensuring that they can accurately align with the wheel. As the first positioning frame 32 and the second positioning frame 37 gradually approach each other, the locking plate 36 wraps around the wheel for a secure fixation.

[0028] The first cylinder 5 provides a stable and controllable driving force, making the entire locking process efficient and reliable, effectively reducing manual intervention and improving production efficiency and safety. This synchronous linkage not only improves the stability of wheel fixing but also shortens adjustment time, thereby enhancing overall assembly efficiency.

[0029] Example 2: Figure 4 As shown, the control mechanism 2 includes a rotating rod 24, the outer surface of which is fixedly connected to the bottom of the mounting frame 4. A gear 23 is fixedly connected to one end of the rotating rod 24. A rack 22 is meshed with the bottom of the gear 23, and a movable frame 25 is fixedly connected to the outer wall of the rack 22. A track 27 is slidably connected to the bottom of the rack 22, and the bottom of the track 27 is fixedly connected to the base plate 1. A fixed plate 26 is fixedly connected to one end of the movable frame 25, and a second cylinder 21 is mounted on the top of the base plate 1. The output end of the second cylinder 21 is fixedly connected to one end of the fixed plate 26.

[0030] The overall effect of this embodiment is that when the second cylinder 21 drives the fixed plate 26 to move, the fixed plate 26, through its connecting structure, drives the movable frame 25 to move together. During this process, the movement of the movable frame 25 directly affects the movement of the rack 22. Since the rack 22 is confined within the track 27, its movement trajectory is constrained, thus ensuring that the rack 22 always moves along a predetermined straight line, avoiding deviation or jamming. Furthermore, the linear movement of the rack 22 ensures stable meshing with the gear 23, preventing transmission failure due to angular deviations.

[0031] As rack 22 moves, gear 23 is driven to rotate, and the rotation of gear 23 further drives rotating rod 24 to rotate. The rotation of rotating rod 24 acts on mounting bracket 4, causing it to change angle, thereby indirectly affecting the adjustment of positioning mechanism 3. Through this transmission method, precise control of the angle of positioning mechanism 3 can be achieved to meet the needs of wheel adjustment under different working conditions.

[0032] It can effectively adjust the position of the wheels to achieve the optimal maintenance angle, improving the convenience of maintenance operations. At the same time, this structure utilizes cylinder drive to achieve automated adjustment, reducing the complexity of manual operation and improving the efficiency and safety of maintenance work.

[0033] The device's operation and working principle are as follows: When fixing the wheel, the first cylinder 5 drives the push rod 31 to move, thereby causing the rotating frame 35 to rotate. During rotation, the rotating frame 35 drives the linkage rod 33 and the transmission rod 34 to move respectively. The linkage rod 33 controls the movement of the first positioning frame 32, and the transmission rod 34 drives the movement of the second positioning frame 37. The first positioning frame 32 and the second positioning frame 37 rotate around the central rod 38 in opposite directions, thus achieving convergence. The locking plate 36 then fixes the wheel, improving the stability and efficiency of positioning.

[0034] Simultaneously, the second cylinder 21 drives the fixed plate 26 to move, and the fixed plate 26 drives the movable frame 25 to move synchronously. During this process, the movable frame 25 pushes the rack 22 to move linearly under the constraint of the track 27, ensuring that the meshing of the rack 22 and the gear 23 does not deviate. The movement of the rack 22 drives the gear 23 to rotate, thereby controlling the rotation of the rotating rod 24, which in turn drives the mounting frame 4 to rotate, so as to adjust the angle of the positioning mechanism 3, making the operation of the wheel more flexible and convenient for maintenance.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
