DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0025] Please refer to Figures 1-4, A high-speed gear hobbing processing device, including a processing table 1, a bearing seat 2, a hobbing rod 3 and an adjusting device. On one side of the top of the processing table 1, the bearing seat 2 is installed. On the top of the bearing seat 2, a mounting shaft 4 is installed. On the top of the mounting shaft 4, a fastening nut 5 is threadedly installed. On the three sides of the top of the processing table 1 away from the bearing seat 2, baffles 6 are fixedly installed. Inside the baffles 6, a sliding frame 7 is installed through the adjusting device. Inside the sliding frame 7, the hobbing rod 3 is rotatably installed. One end of the hobbing rod 3 penetrates through the side wall of the sliding frame 7 and a rotating motor 8 is installed. The adjusting device includes a rectangular groove 9, a threaded rod 10, a slider 11, a driving shaft 12, a driving bevel gear 13, a driven bevel gear 14 and a driving motor 15. On the corresponding two side walls of the baffle 6, rectangular grooves 9 are opened. Inside the rectangular groove 9, the threaded rod 10 is rotatably installed. On the threaded rod 10, the slider 11 is threadedly installed. The two sliders 11 and the left and right side walls of the sliding frame 7 are connected by connecting rods. One end of the threaded rod 10 penetrates through the side wall of the baffle 6 and the driving shafts 12 are respectively installed. On the outer wall of the driving shaft 12, the driven bevel gears 14 are sleeved. On one side of the two driven bevel gears 14, the driving bevel gears 13 are meshed and connected respectively. On the outer side wall of one side of the baffle 6, the driving motor 15 is installed. The output ends of the left and right ends of the driving motor 15 are both connected to the driving bevel gears 13. In this embodiment, when in use, when it is necessary to process a workpiece, first, the workpiece is sleeved on the mounting shaft 4, and then the workpiece is installed on the bearing seat 2. Then, the fastening nut 5 is threadedly fastened to the mounting shaft 4 to fix the gear on the bearing seat 2. Then, the driving motor 15 is started. The output end of the driving motor 15 drives the two driving bevel gears 13 to rotate. The two driving bevel gears 13 drive the two driven bevel gears 14 to rotate. The two driven bevel gears 14 drive the two driving shafts 12 to rotate. During the rotation of the two driving shafts 12, the two threaded rods 10 are driven to rotate in the rectangular grooves 9. During the rotation of the threaded rods 10, the two sliders 11 move linearly in the rectangular grooves 9. The two sliders 11 drive the sliding frame 7 through the connecting rods and move towards the workpiece until the hobbing rod 3 in the sliding frame 7 is driven to move to a position adapted to the workpiece. Then, the driving motor 15 is turned off, which is convenient for adjusting the processing position of the hobbing rod 3 according to the inner diameter of the workpiece. The rotating motor 8 is started. The rotating motor 8 drives the hobbing rod 3 to rotate. The hobbing rod 3 is used to perform hobbing processing on the workpiece. During this process, the hobbing rod 3 makes a rotational motion at a given cutting speed, while the workpiece is driven according to the gear meshing relationship. As the hobbing rod 3 continuously rotates, tooth grooves are cut out on the tooth blank to form an involute tooth surface. When the hobbing rod 3 and the workpiece continuously rotate, all tooth grooves are sequentially cut out on the entire circumference of the workpiece.
[0026] In actual use, it is further convenient to guide the sliding frame 7. In this embodiment, two groups of guide grooves 16 are symmetrically opened on the top of the processing table 1, and a guide rod 17 is fixedly installed in the guide groove 16. A guide block 18 is slidably installed on the guide rod 17. The top wall of the guide block 18 is respectively fixedly connected to the bottom wall of the sliding frame 7. During the movement of the sliding frame 7, the guiding block 18 is driven by the guiding block 18 to slide on the guiding rod 17, so as to guide the movement of the sliding frame 7 and prevent the sliding frame 7 from deviating from the motion trajectory.
[0027] In actual use, in order to further facilitate the collection of debris, in this embodiment, a collection groove 19 is provided on the top wall of the processing table 1 directly below the supporting seat 2, and the collection groove 19 is convenient for collecting the debris generated during the processing.
[0028] In actual use, it is further convenient to collect the debris in the collection tank 19. In this embodiment, a collection head 20 is embedded in the collection tank 19, and a collection box 21 is installed on the bottom wall of the processing table 1. The collection head 20 is connected to the collection box 21. When there are too many debris in the collection tank 19, the debris will enter the collection box 21 along the collection head 20, and the debris in the collection tank 19 will be collected, which is convenient for centralized processing in the next step.
[0029] In actual use, the stability and accuracy of the operation of the drive motor 15 and the rotating motor 8 are further guaranteed. In this embodiment, the drive motor 15 and the rotating motor 8 are both servo motors. The servo motor can control the position, speed and torque with high precision. The servo motor adopts closed-loop control and has good stability. It can avoid problems such as stalling and vibration, thereby ensuring the stability and accuracy of the operation of the drive motor 15 and the rotating motor 8.
[0030] In actual use, in order to further ensure the support stability of the processing table 1, in this embodiment, support legs 22 are installed at the four corners of the bottom end of the processing table 1. The design of installing support legs 22 at the four corners can make the processing table 1 evenly stressed, and this symmetrical layout helps to enhance the stability of the platform.
[0031] Preferably, in this embodiment, the rectangular groove 9 and the guide groove 16 are of equal length, so as to facilitate the positioning of the sliding frame 7 .
[0032] Preferably, in this embodiment, the baffle plate 6 and the sliding frame 7 are both U-shaped in design. The U-shaped design of the baffle plate 6 facilitates blocking debris and preventing it from splashing, and the U-shaped design of the sliding frame 7 facilitates installation of the gear hobbing rod 3.
