Description
Technical Field
[0001] This utility model relates to a parts turnover and transportation device, specifically a transmission shaft outer ring transfer vehicle. Background Technology
[0002] The constant velocity joint driveshaft of a car consists of a fixed end joint, an intermediate shaft, and a moving end joint. The fixed end joint is directly connected to the wheel hub of the car, while the moving end joint is directly connected to the engine differential. Engine power is transmitted to the wheels through the differential, moving end joint, intermediate shaft, fixed end joint, and wheel hub, thus driving the wheels to rotate. The fixed end joint mainly consists of an outer ring, cage, steel balls, and inner ring; the moving end joint mainly consists of an outer sleeve, cage, steel balls, and inner sleeve. The rotation of the outer ring of the fixed end joint is crucial. It must be time-efficient and labor-saving while ensuring that the outer ring is not damaged, especially the spline on the shank. If the spline on the shank is damaged, it will be difficult to assemble with the wheel hub. This is particularly problematic at the OEM plant, where it can lead to production stoppages on the assembly line and customer dissatisfaction. Previously, a layer of outer rings was placed on the partition of the transfer vehicle, and then another partition was placed in between. This was labor-intensive and inefficient for the operators. Sometimes, to save time, the operators would place two layers of outer rings and then place another partition. This would cause the splines on the handle of the outer rings to collide, resulting in the waste of the outer rings being repaired and scrapped. If the outer rings were sent to the OEM, they would be discovered at the assembly site, and the customers would be dissatisfied. Therefore, there is an urgent need at the processing site for a transfer vehicle that saves time and effort while ensuring that the outer rings do not collide. Summary of the Invention
[0003] The purpose of this invention is to provide a transmission shaft outer ring transfer vehicle. Using this technology, the transmission shaft outer ring can be operated efficiently, which not only reduces the labor intensity of the operator, but also ensures that the spline of the outer ring shank does not collide.
[0004] The technical solution of this utility model is: a transmission shaft outer ring transfer vehicle, including a frame and wheels mounted at the bottom of the frame. A handle A is fixedly mounted on one side of the frame. The frame is fixedly connected to columns A, B, and C. Rotating trays A, B, and C, and a fixed tray are installed in the frame from top to bottom. Each tray has a frame around its perimeter and a reinforcing rib at its bottom. The fixed tray is fixedly connected to the frame through the frame. The frames of rotating trays A, B, and C are rotatably connected to column C through their corresponding hinges. A stop block is fixedly mounted on the frame. When rotating trays A, B, and C are rotated to a horizontal position, they press against the stop block. The frames on both sides of rotating trays A, B, and C are respectively connected to the frame through their corresponding rotation limiting components.
[0005] The rotation limiting assembly includes: a gas spring, a support plate, connector A, connector B, connector C, hinge rod A, hinge rod B, shaft A, and shaft B. Connector A is fixedly connected to the side frame of the corresponding rotating tray A, rotating tray B, and rotating tray C, respectively. Connector B is fixedly connected to column A. One end of the gas spring is hinged to one end of hinge rod A. The other end of hinge rod A is provided with a screw, which passes through a hole in connector A and is clamped and fixed by nuts A and B. The other end of the gas spring is hinged to one end of hinge rod B. The other end of hinge rod B is provided with a screw, which passes through a hole in connector B. The components are clamped and fixed by nuts C and D. The connecting piece C is fixedly connected to the corresponding rotating tray A, rotating tray B, and the frame on the other side of the rotating tray C. One end of shaft A is fixedly connected to the connecting piece C. One end of the support plate is rotatably connected to shaft A. The other end of shaft A is provided with a screw. Nut E is screwed to the screw on shaft A. Column B is fixedly connected to one end of shaft B. The other end of shaft B is provided with a screw. The support plate is provided with a long groove, which is fitted and slidably connected to shaft B. Nut F is screwed to the screw on shaft B. The support plate is provided with a short groove, which is perpendicular to the long groove. The short groove is provided with an upper end and a lower end.
[0006] The wheels are polyurethane wheel A and polyurethane wheel B. Polyurethane wheel A is rotatably connected to a universal wheel frame fixed to the bottom of the frame, and polyurethane wheel B is rotatably connected to a directional wheel frame fixed to the bottom of the frame.
[0007] A handle B is fixed to the edge of the rotating tray A.
[0008] The principle of this invention is as follows: Due to the supporting, buffering, braking, and relatively controllable characteristics of the gas spring, during the process of each rotating tray being pushed upward and rotating around the hinge, the gas spring provides smooth support while preventing it from falling back. The long groove of the support plate slides relative to the shaft B. As the rotating tray continues to rotate, the shaft B slides out of the long groove of the support plate and is located at the lower end of the short groove of the support plate. The support plate falls under its own weight, and the shaft B is located at the upper end of the short groove. The support plate keeps the rotating tray in place and prevents it from falling. After the lower rotating tray is filled with the outer ring (workpiece), the short groove end of the support plate is lifted upward so that the shaft B is located at the lower end of the short groove (at this time, due to the buffering and supporting effect of the gas spring, the rotating tray will not fall). At the same time, the rotating tray is pulled downward, and the shaft B slides in the long groove until the rotating tray is in a horizontal position and contacts the stop block. Then the outer ring is filled again. The same steps are repeated until the uppermost rotating tray is filled with the outer ring.
[0009] The advantages of this invention are: it can efficiently operate the outer ring of the drive shaft, reducing the operator's workload and ensuring that the spline on the outer ring's shank does not collide. Previously, an outer ring was placed on a partition in a transfer cart, separated by another partition. This resulted in high operator workload and low efficiency. Sometimes, to save time, operators would place two layers of outer rings and then add another partition, which could cause the spline on the outer ring's shank to collide, leading to wasted repairs. If the ring was sent to the OEM, this would be discovered at the assembly site, causing customer dissatisfaction. This invention can also operate moving end caps or other similar parts with shanks.

The polyurethane wheel B2 is rotatably connected to the directional wheel frame 1 fixed to the bottom of the frame 25. The fixed tray 7 has a frame 26 around its perimeter and a reinforcing rib 3 at its bottom. The fixed tray 7 is fixedly connected to the frame 25 and is located at the bottom layer. The rotating tray A18... Rotary trays B23 and C24 are all equipped with side frames 26 and reinforcing ribs 3 at the bottom. The side frames 26 of rotating trays A18, B23, and C24 are rotatably connected to the column C4 through corresponding hinges 10. When rotating trays A18, B23, and C24 are in a horizontal position, they are supported by blocks 8 fixed to the frame 25. The handle B16 is fixed to the side frame 26 of rotating tray A18. Rotary tray A18 is located on the top layer of the trays. Since the top tray is at a higher position, it is easy to push or pull the rotating tray up or down through the handle B16. The side frames 26 of rotating trays A18, B23, and C24 are connected to the frame 25 through their corresponding rotation limit components.
[0024] The rotation limiting assembly includes: a gas spring 11, a support plate 22, a connector A15, a connector B27, a connector C19, a hinge rod A13, a hinge rod B29, a shaft A21, and a shaft B32. The side frames 26 of the rotating trays A18, B23, and C24 are all fixedly connected to their corresponding connectors A15. A connector B27 is fixedly connected to the column A34. One end of the gas spring 11 is hinged to one end of the hinge rod A13. The other end of the hinge rod A13 is provided with a screw. The screw passes through a hole in the connector A15, and nuts A14 and B12 fix the hinge rod A13 to the connector A15. The other end of the gas spring 11 is hinged to one end of the hinge rod B29. The other end of the hinge rod B29 is provided with a screw. The screw passes through a hole in the connector B27, and nuts C28 and D30 fix the hinge rod B29 to the connector B29. 9 is fixedly connected to connector B27. The other side frame 26 of the rotating tray A18, rotating tray B23, and rotating tray C24 is fixedly connected to connector C19. One end of shaft A21 is fixedly connected to connector C19. One end of support plate 22 is rotatably connected to shaft A21. The other end of shaft A21 is provided with a screw. Nut E20 is screwed to the screw on shaft A21 to prevent support plate 22 from detaching from shaft A21. Column B33 is fixedly connected to one end of shaft B32. The other end of shaft B32 is provided with a screw. Support plate 22 is provided with a long groove 35. Long groove 35 is fitted and slidably connected to shaft B32. Nut F31 is screwed to the screw on shaft B32 to prevent support plate 22 from detaching from shaft B32. Support plate 22 is provided with a short groove 36. Short groove 36 is perpendicular to long groove 35. Short groove is provided with upper end 38 and lower end 37.
[0025] The gas spring 11 is an industrial accessory that uses gas pressure to generate elasticity. It is existing technology. The gas spring 11 is selected in this utility model because, compared with ordinary springs, it has advantages such as relatively slow speed, small dynamic force change, and easy control.
[0026] The outer ring is the workpiece loaded and transported by the transfer vehicle of this utility model. The spline of the handle of the outer ring is located at the end of the main body. During transfer, the spline of the handle is easily bumped. This utility model is a transfer vehicle that ensures that the spline of the handle of the outer ring will not be bumped.
[0027] The working process of this utility model is as follows: Holding the handle B16, first push the uppermost rotating tray A18 upwards to rotate around the hinge 10. During the rotation, the gas spring 11 provides smooth support while preventing the rotating tray A18 from falling back. The long groove 35 of the support plate 22 slides relative to the shaft B32. As the rotating tray A18 continues to rotate, the shaft B32 slides out of the long groove 35 of the support plate 22 and is located at the lower end 37 of the short groove of the support plate 22. The support plate 22 falls under its own weight, and the shaft B32 is located at the upper end 38 of the short groove. The support plate 22 keeps the rotating tray A18 locked and prevents it from falling. Following the same steps, the rotating trays B18 on the fixed tray 7 are then moved one by one. 23. The rotating pallet C24 is lifted upward and held in place by the support plate 22. After the outer ring is filled on the bottom fixed pallet 7, the short groove end of the support plate 22 on the rotating pallet C24 adjacent to the fixed pallet 7 is lifted upward so that the shaft B32 is located at the lower end 37 of the short groove (at this time, due to the buffer support of the gas spring 11, the rotating pallet C24 will not fall). At the same time, the rotating pallet C24 is pulled downward, and the shaft B32 slides in the long groove 35 until the rotating pallet C24 is in a horizontal position and contacts the stop 8. Then the outer ring is filled on the rotating pallet C24. The same steps are repeated to fill the outer rings on the rotating pallet B23 and the rotating pallet A18. The pallet is then transported to the next processing or assembly process by the transfer car.
