[0008] To increase the stability of the toothed plate during sliding, the sliding assembly includes a slider and a drive block. The slider is fixedly connected to the bottom plate of the toothed plate. A sliding groove is provided on the moving frame, and the slider is slidably connected in the sliding groove. The drive block is fixedly connected to the bottom end of the slider, and the output end of the first hydraulic cylinder is fixedly connected to the drive block.

[0009] To drive the loading rack to move up and down, the lifting mechanism includes: a fixed frame, a sliding cylinder, a sliding rod, and a second hydraulic cylinder. The fixed frame is fixedly connected to the swing frame. There are two sliding cylinders, both of which are fixedly connected to the top of the swing frame. There are two sliding rods, both of which are fixedly connected to the bottom of the loading rack. The two sliding rods are slidably connected to the two sliding cylinders respectively. The second hydraulic cylinder is installed in the fixed frame, and the output end of the second hydraulic cylinder passes through the fixed frame and is fixedly connected to the loading rack.

[0010] In order to support the rod shaft to move into the broaching equipment body, the conveying mechanism includes: a conveying trough, a conveying plate and a conveying wheel.

When the rod shaft to be processed is long, a moving mechanism moves the position of the loading rack. Therefore, this application facilitates loading thicker rod shafts, saving time and effort and improving the processing efficiency of the rod shaft. Attached Figure Description

[0024] like Figures 1-7The diagram illustrates a rod / shaft keyway machining apparatus according to an embodiment of this disclosure. It includes a broaching equipment body 1, a moving frame 2, a swing frame 3, a loading frame 4, and a conveying mechanism. A guide block 22 is fixedly connected to the broaching equipment body 1. A guide groove 23 is formed on the moving frame 2, and the guide block 22 is fixedly connected within the guide groove 23. The moving frame 2 is mounted on the broaching equipment body 1 via a rotating mechanism, which drives the moving frame 2 to move on the broaching equipment body 1. The swing frame 3 is mounted on the top of the moving frame 2 via a swing mechanism, which drives the swing frame 3 to tilt and swing. The loading frame 4 is mounted on the swing frame 3 via a lifting mechanism, which drives the loading frame 4 to move forward. The height is adjustable. The conveying mechanism is set on the loading rack 4 and is used to convey the rod shaft on the loading rack 4 into the broaching equipment body 1. The loading rack 4 is driven to swing downward to the external unloading rack by the swinging mechanism, pushing the rod shaft into the loading rack 4. Then, the swinging mechanism drives the loading rack 4 to return to the center. After that, the lifting mechanism drives the loading rack 4 to rise to the broaching opening on the broaching equipment body 1. Then, the operator pushes the rod shaft, and the rod shaft smoothly enters the broaching opening through the conveying mechanism. When the rod shaft to be processed is long, the position of the loading rack 4 is moved by the moving mechanism. Therefore, this application is convenient for replacing the operator to load thicker rod shafts, which is more time-saving and labor-saving, and improves the processing efficiency of rod shafts.

[0025] The rotating mechanism includes a rack 5, a rotating shaft 6, a drive gear 7, and a first motor 8. A mounting frame 25 is fixedly connected to the broaching equipment body 1. The first motor 8 is mounted on the mounting frame 25. There are two racks 5, each fixedly connected to the top of the movable frame 2, and the two racks 5 are located on opposite sides of the broaching equipment body 1. The rotating shaft 6 is rotatably connected inside the broaching equipment body 1. There are two drive gears 7, each fixedly connected to both ends of the rotating shaft 6. The two drive gears 7 mesh with the two racks 5. The first motor 8 is mounted on one side of the broaching equipment body 1. The output end of the first motor 8 is fixedly connected to one of the drive gears 7. The first motor 8 drives one of the drive gears 7 to rotate, and through the transmission of the rotating shaft 6, it drives the two drive gears 7 to rotate synchronously. Since the two racks 5 mesh with the two drive gears 7, the movable frame 2 is moved.

[0026] The swing mechanism includes a swing rod 9, a transmission gear 10, a toothed plate 11, and a first hydraulic cylinder 12. Two stabilizing plates 24 are fixedly connected to the top of the movable frame 2. Each stabilizing plate 24 has a rotating hole. The two ends of the swing rod 9 are rotatably connected to the two rotating holes, and the swing rod 9 is rotatably connected to the top of the movable frame 2. A swing frame 3 is fixedly connected to the swing rod 9. The transmission gear 10 is fixedly connected to the swing rod 9. The toothed plate 11 is slidably connected to the top of the movable frame 2 via a sliding assembly, and the toothed plate 11 meshes with the transmission gear 10. The first hydraulic cylinder 12 is installed at the bottom of the movable frame 2. The output end of the first hydraulic cylinder 12 is fixedly connected to the sliding assembly. The sliding assembly includes a slider 13 and a drive block 14. The slider 13 is fixedly connected to the drive block 14. The base plate of the toothed plate 11 is fixedly connected to the movable frame 2. A sliding groove is provided on the movable frame 2. The slider 13 is slidably connected in the sliding groove. The drive block 14 is fixedly connected to the bottom end of the slider 13. The output end of the first hydraulic cylinder 12 is fixedly connected to the drive block 14. The first hydraulic cylinder 12 drives the drive block 14 and the slider 13 to move. When the movable block moves, it drives the toothed plate 11 to move. Since the toothed plate 11 meshes with the transmission gear 10, it drives the transmission gear 10 and the swing rod 9 to rotate. This causes the swing frame 3 and the loading frame 4 to flip to one side and move closer to the external unloading frame. Then, the operator pushes the rod shaft into the loading frame 4. Then, the first hydraulic cylinder 12 drives the toothed plate 11 to move in the opposite direction, thereby making the loading frame 4 return to the center and lifting the rod shaft.

[0027] The lifting mechanism includes: a fixed frame 15, a slide cylinder 16, a slide rod 17, and a second hydraulic cylinder 18. The fixed frame 15 is fixedly connected to the swing frame 3. There are two slide cylinders 16, both of which are fixedly connected to the top of the swing frame 3. There are two slide rods 17, both of which are fixedly connected to the bottom of the loading frame 4. The two slide rods 17 are slidably connected to the two slide cylinders 16 respectively. The second hydraulic cylinder 18 is installed in the fixed frame 15. The output end of the second hydraulic cylinder 18 passes through the fixed frame 15 and is fixedly connected to the loading frame 4. The second hydraulic cylinder 18 installed on the fixed frame 15 drives the loading frame 4 to rise, thereby driving the rod shaft inside the loading frame 4 to rise to the height of the broaching hole.

[0028] The conveying mechanism includes a conveying trough 19, a conveying plate 20, and conveying wheels 21. The circumferential surfaces of the multiple conveying wheels 21 are all arc-shaped. The conveying trough 19 is located on the loading rack 4. There are two conveying plates 20, which are fixedly connected to the conveying trough 19. There are multiple conveying wheels 21, which are rotatably connected between the two conveying plates 20. When the operator pushes the rod shaft, it is rolled by the multiple conveying wheels 21, thereby conveying the rod shaft into the broaching hole.

[0029] Working principle: When keyway machining of shafts is required, a large number of shafts are typically placed on an external feeding rack. Then, a first motor 8 drives one of the drive gears 7 to rotate, which in turn drives two other drive gears 7 to rotate synchronously via the rotating shaft 6. Since the two racks 5 mesh with the two drive gears 7, the moving frame 2 moves. The moving frame 2 moves the feeding rack 4, thus adjusting the position of the feeding rack 4 according to the storage location of the shafts. Then, the first hydraulic cylinder 12 drives the drive block 14 and the slider 13 to move. The movement of the drive block moves the toothed plate 11. The toothed plate 11 meshes with the transmission gear 10, thereby driving the transmission gear 10 and the swing rod 9 to rotate. This, in turn, causes the swing frame 3 and the loading frame 4 to flip to one side, closer to the external unloading frame. Then, the operator pushes the rod shaft into the loading frame 4. After that, the first hydraulic cylinder 12 drives the toothed plate 11 to move in the opposite direction, thereby turning the loading frame 4 back to the center and lifting the rod shaft. The second hydraulic cylinder 18 installed on the fixed frame 15 drives the loading frame 4 to rise, thereby raising the rod shaft inside the loading frame 4 to the height of the broaching hole. The operator pushes the rod shaft, which is then rolled by multiple conveying wheels 21, thereby conveying the rod shaft into the broaching hole for processing.

[0030] Additionally, it should be noted that the broaching equipment body 1 is a common keyway processing equipment on the market. Its principle is based on a broach and a broaching machine. The principle is to use the linear motion of the broach to cut the workpiece to form a keyway. The cutting teeth on the broach increase in height from front to back, cutting the material tooth by tooth. Finally, the material is polished and the dimensions are calibrated by the calibration teeth. Since this application does not make any internal improvements to the broaching equipment, it will not be described in detail here.

[0031] It should also be noted that the first motor 8 is a reversible motor, and its forward or reverse rotation can be adjusted according to actual usage requirements.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
