Description

Technical Field

[0001] This utility model relates to the field of rail vehicle coupler processing technology, specifically to a rail vehicle coupler installation and manufacturing tooling fixture. Background Technology

[0002] A rail vehicle coupler is a hook at both ends of a car or locomotive, which serves to connect, pull, and buffer. The coupler is a vehicle component used to connect locomotives and cars or cars and cars, to transmit traction and impact forces, and to maintain a certain distance between cars. During the manufacturing and processing of rail vehicle couplers, tooling fixtures are needed to stabilize and fix them to enhance stability during processing.

[0003] Currently, existing rail vehicle coupler tooling fixtures are limited to clamping and fixing the coupler. When it is necessary to process the coupler in all directions during the coupler manufacturing process, it is necessary for the staff to operate and rotate the coupler for adjustment. Since the coupler has a certain weight, manual rotation is quite troublesome.

[0004] In summary, there is a current need for a manufacturing fixture for the installation of rail vehicle couplers. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a manufacturing fixture for the installation of couplers on rail vehicles, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A manufacturing fixture for installing a rail vehicle coupler includes a clamping platform. A drive shaft is rotatably connected to the inner top of the clamping platform. A placement platform is fixedly connected to the upper end of the drive shaft. A first gear is disposed through the outer ring of the drive shaft. The first gear meshes with a second gear. The second gear is disposed through a first rotating shaft. The first rotating shaft is connected to the output shaft of a first motor.

[0008] Furthermore, a first lead screw is rotatably connected to the inner wall of the clamping table, and a movable adjustment frame is installed through the first lead screw. The movable adjustment frame is located on the right side of the mounting platform. The first lead screw is connected to a second rotating shaft via a toothed belt, and the second rotating shaft is connected to the output shaft of a second motor.

[0009] Furthermore, the placement platform includes an opening slot, an opening slot is provided on the right side of the placement platform, and through slots are provided on the upper end of the placement platform near the front and rear sides. A second lead screw is rotatably connected to the inner wall of the through slot, and one end of the second lead screw passes through the placement platform and is connected to the output shaft of the third motor.

[0010] Furthermore, the placement platform also includes a movable frame, through which the movable frame is mounted on the second lead screw, and through which a first hydraulic telescopic rod is mounted, with the inner end of the first hydraulic telescopic rod connected to a first clamp.

[0011] Furthermore, the movable adjustment frame includes a fourth motor, which is installed inside the movable adjustment frame. The output shaft of the fourth motor is connected to a third rotating shaft, and the left end of the third rotating shaft passes through the movable adjustment frame and is connected to the limiting sleeve.

[0012] Furthermore, the movable adjustment frame also includes a second hydraulic telescopic rod, through which the second hydraulic telescopic rod is provided on the side wall of the limiting sleeve, and the inner end of the second hydraulic telescopic rod is fixedly connected to the second clamp.

[0013] This utility model provides a manufacturing fixture for installing couplers on rail vehicles. Compared with the prior art, it has the following advantages:

[0014] First, the rail vehicle coupler is placed on the mounting platform. A third motor and a second lead screw move the movable frame on the second lead screw to adjust its position. A first hydraulic telescopic rod pushes the first clamp to stably clamp and fix the rail vehicle coupler. When the rail vehicle coupler needs to be rotated for adjustment, a second motor, a second rotating shaft, and a toothed belt drive the first lead screw to rotate, causing the movable frame to move to the left on the first lead screw, allowing one end of the rail vehicle coupler to extend into the limiting sleeve. Under the action of the second hydraulic telescopic rod, the second clamp is pushed to limit and fix the rail vehicle coupler. The movable frame moves to the right on the first lead screw to adjust its position. Under the action of the first motor, the first rotating shaft, the second gear, and the first gear, the mounting platform is rotated 90 degrees via the transmission shaft. At this time, a fourth motor and a third rotating shaft drive the limiting sleeve to rotate, causing the rail vehicle coupler to rotate for adjustment. After the rail vehicle coupler is rotated and adjusted, the mounting platform is rotated back to its original position, and the rail vehicle coupler is placed on the mounting platform and fixed for subsequent processing.

[0025] The first motor 7, the first rotating shaft 6, the second gear 5 and the first gear 4 drive the placement platform 3 to rotate 90 degrees through the transmission shaft 2 for adjustment.

The second rotating shaft 11 is connected to the output shaft of the second motor 12.

[0027] The second motor 12, the second rotating shaft 11 and the toothed belt 10 drive the first lead screw 8 to rotate, causing the movable adjustment frame 9 to move to the left on the first lead screw 8, so that one end of the rail vehicle coupler extends into the limit sleeve 903.

[0028] Example 2

[0029] like Figures 1-4 As shown, based on the above embodiments, this embodiment further provides the following:

[0030] In this embodiment, the placement platform 3 includes an opening slot 301. The opening slot 301 is opened on the right side of the placement platform 3. The upper end of the placement platform 3 is provided with through slots 302 near the front and rear sides. The inner wall of the through slot 302 is rotatably connected to a second lead screw 303.

[0031] The third motor 305 and the second lead screw 303 cause the movable frame 304 to move and adjust to an appropriate position on the second lead screw 303, and the first hydraulic telescopic rod 306 pushes the first clamp 307 to stably clamp and fix the coupler of the rail vehicle.

[0032] Example 3

[0033] like Figures 1-4 As shown, based on the above embodiments, this embodiment further provides the following:

[0034] In this embodiment, the movable adjustment frame 9 includes a fourth motor 901, which is installed inside the movable adjustment frame 9.

[0036] Working principle and usage process of this utility model:

[0037] In use:

[0038] Step 1: By placing the rail vehicle coupler on the placement platform 3, the moving frame 304 is moved and adjusted to an appropriate position on the second lead screw 303 by the third motor 305 and the second lead screw 303. The first clamp 307 is pushed by the first hydraulic telescopic rod 306 to stably clamp and fix the rail vehicle coupler, and then it is processed.

[0039] Step 2: When the rail vehicle coupler needs to be rotated and adjusted, the second motor 12, the second rotating shaft 11 and the toothed belt 10 drive the first lead screw 8 to rotate, causing the movable adjustment frame 9 to move to the left on the first lead screw 8, so that one end of the rail vehicle coupler extends into the limiting sleeve 903. Under the action of the second hydraulic telescopic rod 904, the second clamp 905 is pushed to limit and fix the rail vehicle coupler. Then, the second motor 12, the second rotating shaft 11 and the toothed belt 10 drive the first lead screw 8 to rotate, causing the movable adjustment frame 9 to move to the right on the first lead screw 8 to adjust to the appropriate position.

[0040] Step 3: Under the action of the first motor 7, the first rotating shaft 6, the second gear 5 and the first gear 4, the placement platform 3 is rotated 90 degrees through the transmission shaft 2 for adjustment. At this time, the fourth motor 901 and the third rotating shaft 902 drive the limit sleeve 903 to rotate, thereby driving the rail vehicle coupler to flip and adjust. After the rail vehicle coupler is flipped and adjusted, the placement platform 3 is rotated and adjusted to its original position, and the rail vehicle coupler is placed on the placement platform 3 and fixed for subsequent processing.
