Description

Technical Field

[0001] The utility model relates to the technical field of axle transmission, in particular to an automatic axle transmission mechanism. Background Art

[0002] A high-speed rail axle refers to a bearing component used for high-speed railway trains and is an important part connecting the wheels. The high-speed rail axle undertakes the functions of supporting the weight of the train, transmitting power, and maintaining the stability of the train. During the running of high-speed trains, the high-speed rail axle needs to bear huge challenges brought by factors such as the weight of the train, speed, and curve running, so it needs to have the characteristics of high strength, wear resistance, and high precision.

[0003] Chinese Patent with the publication number CN218172305U discloses an axle transfer device, and the technical solution disclosed in this patent document is as follows: It includes a bottom plate and a running device. The running device includes structures such as side plates, a fixed top frame, a connecting plate, and support columns; one side of the bottom plate is fixedly connected to one side of the side plate. By setting structures such as a chute column and an electric telescopic rod, by starting the electric telescopic rod, the electric telescopic rod drives the sliding block to slide in the chute column to realize the transfer and transportation of the axle. However, the above solution will still have the problem that the axle will shift during transportation, resulting in inconvenient subsequent operations. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose an automatic axle transmission mechanism, and one of the technical problems it solves is the problem that the existing mechanism shifts during the transportation of the axle, resulting in inconvenient subsequent operations.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An automatic axle transmission mechanism includes an outer frame structure. Two rotating grooves are symmetrically arranged at the top of the outer frame structure. A first meshing wheel is rotatably connected to the inside of each rotating groove. A threaded rod is fixedly connected to the side of the first meshing wheel close to each other. A correction plate is threadedly connected to the outside of the threaded rod. The correction plate slides relative to the outer frame structure. Rotating the threaded rod controls the correction plate to move towards the inside to complete the position correction of the axle. Thus, the position of the axle can be corrected by clamping on both sides.

[0007] As a further improvement of the utility model, sliding blocks are fixedly connected to the bottom ends of the correction plates. Anti-friction plates are slidably connected to the sides of the two correction plates close to each other. Support rods are fixedly connected to the sides of the two correction plates away from each other. Shrinkage rods are symmetrically and fixedly connected to the sides of the correction plates close to the outer frame structure at the top. Thus, the possibility of the correction plate deforming can be reduced.

[0008] As a further improvement of the present utility model, moving grooves are symmetrically opened at the top end of the outer frame structure, and the two rotating grooves are respectively opened inside the two moving grooves. Thereby, the grasping mechanism can be made to slide.

[0009] As a further improvement of the present utility model, a fixing mechanism is fixedly connected to the bottom end of the outer frame structure, and limiting grooves are symmetrically opened on the bottom surface of the outer frame structure. The two sliding blocks are slidably connected inside the two limiting grooves. Thereby, the correction plate can be limited and play a supporting role.

[0010] As a further improvement of the present utility model, a number of second meshing wheels are symmetrically and slidably connected inside the moving grooves. Limiting rods are rotatably connected to both sides of the second meshing wheels, and the top ends of the limiting rods are fixedly connected to two transmission structures respectively located at the top of the moving grooves. Thereby, the grasping mechanism can be made to slide.

[0011] As a further improvement of the present utility model, a support beam is fixedly connected to the top end of the transmission structure, a vertical contraction mechanism is fixedly connected to the middle of the bottom end of the support beam, and a grasping mechanism is fixedly connected to the bottom end of the vertical contraction mechanism. Thereby, the axle can be clamped.

[0012] As a further improvement of the present utility model, a number of the second meshing wheels are respectively meshed with the first meshing wheels on both sides. Thereby, the offset of the axle during the transportation of the axle can be adjusted.

[0013] As a further improvement of the present utility model, a soft pad is fixedly connected to the inner wall of the clamping part at the bottom end of the grasping mechanism. Thereby, the surface of the axle can be prevented from being scratched during the grasping process.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. Through the correction plate, threaded rod, first meshing wheel, and second meshing wheel, after the axle is clamped, the second meshing wheel can be made to roll along the inside of the moving groove by starting the transmission structure. When the second meshing wheel meshes with the first meshing wheel, it will drive the first meshing wheel to rotate, thereby driving the threaded rod to rotate. Due to the threaded connection between the threaded rod and the correction plate, the correction plates at both ends will move towards the middle to correct the axle. An accurate axle position can reduce errors and defects during production, lower the scrap rate, and improve production efficiency. Moreover, correcting the axle position can also ensure the normal operation of the production line, avoiding production interruptions or delays caused by inaccurate axle positions. By correcting the axle position in advance during the production process, additional costs for subsequent maintenance and adjustment can be avoided, improving the production cost-effectiveness. By correcting the axle position, it can also ensure that the geometry and dimensions in axle production more conform to the standard requirements, thereby improving product quality and reliability. Through the correction plate, the axle can also be corrected, thus simplifying the structural design of the top support beam and enabling the grasping mechanism to transmit the axle with only one-way movement.

[0016] 2. Through the limit groove, sliding block, correction plate, and support rod, the sliding block fixedly connected to the bottom end of the correction plate is slidably connected inside the limit groove opened on the bottom surface of the outer frame structure, thereby limiting the position of the correction plate. With the support of the support rod for the correction plate, when correcting the position of the axle, the correction plate will not deform. Keeping the correction plate from deforming can ensure its accuracy, thereby ensuring that the correction of the axle position is also accurate, avoiding possible errors. Not deforming means that the correction plate has a longer service life and can be continuously used for correcting the axle position, reducing the need for replacement and maintenance. Moreover, the non-deforming correction plate has better stability and can maintain a stable working state during the axle correction process, ensuring the consistency and reliability of the correction results. Reducing the deformation of the correction plate can lower the maintenance and replacement costs, improve the cost-effectiveness of the equipment, and be conducive to the continuous progress of production and the stability of operation.

Detailed implementation manner

[0022] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific implementations disclosed below.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only and do not represent the only implementation manner.

[0024] The following will further describe the present utility model with reference to the accompanying drawings.

[0025] As shown in the figure, an automatic axle transmission mechanism includes a correction plate 107, a threaded rod 111, and a first meshing wheel 112.

[0026] When the transmission structure 204 is started to drive the support beam 203 to move above the axle, the grasping mechanism 201 is moved to the axle by starting the up-and-down retracting mechanism 202, and then the axle is clamped by starting the grasping mechanism 201. At this time, the fixing mechanism 102 for fixing the axle is loosened, and then the axle is taken out by retracting the up-and-down retracting mechanism 202.

[0027] Then, through the transmission structure 204, the second meshing wheel 205 moves along the inside of the moving groove 103. When the second meshing wheel 205 moves to the top of the first meshing wheel 112, the second meshing wheel 205 will mesh with the first meshing wheel 112 at this time. Thus, during the forward movement of the second meshing wheel 205, it will drive the first meshing wheel 112 to rotate. Since the threaded rod 111 is fixedly connected to the side of the first meshing wheel 112, and the correction plate 107 is threadedly connected to the threaded rod 111, and the retraction rod 110 fixedly connected to the back of the correction plate 107 limits the correction plate 107, the correction plate 107 will move inward along the threaded rod 111, so that the correction plates 107 at both ends move towards the middle to correct the axle that has moved to this position. An accurate axle position can reduce errors and defects during production, reduce the scrap rate, and improve production efficiency. Moreover, correcting the axle position can also ensure the normal operation of the production line and avoid production interruptions or delays caused by inaccurate axle positions.

[0028] Furthermore, since the anti-friction plate 108 is arranged on the movement track of the axle, when the axle contacts the anti-friction plate 108 driven by the grasping mechanism 201, the anti-friction plate 108 contacts the axle at this time. Since the anti-friction plate 108 is slidably connected to the side of the correction plate 107, the anti-friction plate 108 is driven by the axle to slide under the drive of the frictional force at this time, so as to reduce the wear on both ends of the axle during the correction process. Reducing the wear on both ends of the axle can reduce the maintenance and replacement costs, reduce the production line downtime, reduce the maintenance cost, and improve the production efficiency. It can also reduce the number of equipment repairs and replacements at both ends of the axle, improve the stability and continuity of the production line, and thus improve the production efficiency and output.

[0029] Furthermore, the sliding block 106 fixedly connected to the bottom end of the correction plate 107 is slidably connected to the inside of the limiting groove 105 opened on the bottom surface of the outer frame structure 101, so as to limit the position of the correction plate 107. Moreover, it can also make the reaction force received by the correction plate 107 during the axle correction more evenly distributed. Supported by the support rod 109 on the back of the correction plate 107, when correcting the position of the axle, the correction plate 107 will not deform, and keeping the correction plate 107 unchanged can ensure its accuracy, thus ensuring the accuracy of the axle position correction and avoiding possible errors. Not deforming means that the correction plate 107 has a longer service life, can be continuously used for axle position correction, and reduces the need for replacement and maintenance.

[0030] The advantages of the present utility model are as follows: 1) The correction plates 107 at both ends correct the axle towards the middle. An accurate axle position can reduce errors and defects during the production process, lower the scrap rate, and improve production efficiency. 2) It can reduce the wear on both ends of the axle during the correction process. Reducing the wear on both ends of the axle can lower the maintenance and replacement costs, reduce the downtime of the production line, reduce the maintenance expenses, and improve the production benefits. 3) Being able to keep the correction plate 107 unchanged can ensure its accuracy, thereby ensuring that the correction of the axle position is also accurate and avoiding possible errors. 4) It can prevent the surface of the axle from being scratched during the grasping process of the axle.

[0031] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present utility model.
