[0018] Please see Figure 1-5 This utility model provides a drilling device for machining reducer gears: it includes a drilling device base 1, a support rod 2 fixedly connected to the upper end of the drilling device base 1, and a support plate 5 fixedly connected to the support rod 2. The device is characterized in that: a placement plate 6 is fixedly connected to the upper end of the support plate 5, and a limiting mechanism is provided at the upper end of the placement plate 6. The limiting mechanism includes a movable strip 7 slidably connected to the upper end of the placement plate 6, a moving groove 8 opened on one side of the movable strip 7, a clamping plate 9 slidably connected inside the moving groove 8, a moving rod 11 passing through and rotatably connected to the clamping plate 9, a first gear 12 fixedly connected to one end of the moving rod 11 located outside the movable strip 7, a connecting ring 13 fixedly connected to the clamping plate 9, the connecting ring 13 being sleeved on the moving rod 11, and the placement plate 6 for placing the reducer gear to be machined.

[0019] A spiral groove is provided on the outer wall of the moving rod 11, and a slider is fixedly connected to the inner wall of the connecting ring 13. The slider is located inside the spiral groove. When the moving rod 11 rotates with the first gear 12, the spiral groove moves based on the slider, thereby pushing the connecting ring 13 to move laterally. The spiral grooves corresponding to every two adjacent connecting rings 13 are in opposite directions, thereby realizing the opposite movement of the clamping plate 9.

[0020] Two sets of limiting mechanisms are provided, symmetrically distributed above the placement plate 6. The placement plate 6 is located at the center of the support plate 5. The two sets of limiting mechanisms can simultaneously fix the teeth on both sides of the reducer gear to ensure the stability of the gear during drilling.

[0021] Each movable bar 7 has three moving slots 8. Each moving slot 8 has two clamping plates 9 slidably connected inside. When the two clamping plates 9 inside each moving slot 8 move, their moving directions are opposite, which can complete the clamping and releasing of the gear teeth.

[0022] The upper end of the placement plate 6 is provided with a toothed bar 19. When the first gear 12 moves, it can contact the toothed bar 19. When the first gear 12 contacts the toothed bar 19, the two mesh, which pushes the first gear 12 and the moving rod 11 to rotate synchronously. Then, under the action of the spiral groove and the slider, the connecting ring 13 and the clamping plate 9 are moved. The toothed bar 19 is adjusted based on the placement plate 6. The adjustment method can be achieved by rotating a common spiral rod, which is not shown in the figure.

[0023] The upper end of the placement plate 6 is provided with a movable mechanism, which includes a limiting strip 14 fixedly connected to the upper end of the placement plate 6. A drive gear 16 is rotatably connected inside the limiting strip 14, and a rack 17 is slidably connected inside the limiting strip 14. The drive gear 16 meshes with the rack 17. The limiting strip 14 is placed parallel to the placement plate 6 and is located at the upper edge of the placement plate 6, for fixing the gear to be processed from above.

[0024] The moving mechanism also includes a drive motor 18 mounted on the limit bar 14. The output shaft of the drive motor 18 is connected to the drive gear 16. A slide groove 15 is provided on the limit bar 14. A rack 17 passes through the slide groove 15 and is connected to the moving bar 7. There are two slide grooves 15 and two racks 17, which are respectively connected to two moving bars 7. When the drive motor 18 is working, it can drive the drive gear 16 to rotate synchronously, and then drive the rack 17 that meshes with it to move, thereby realizing the movement of the moving bar 7.

[0025] The upper end of the support rod 2 is fixedly connected to the drive component 3, and the output end of the drive component 3 is connected to the drill bit 4. The drill bit 4 is located directly above the support plate 5. When the drive component 3 is working, it can drive the drill bit 4 to move downward and make it rotate, thus completing the drilling work of the gear.

[0026] The working principle of this utility model is as follows: When drilling holes in the gear reducer, the position of the toothed bar 19 can be adjusted according to the size of the gear so that the lateral length can be just right to fix the gear. Then, the gear to be processed is placed on the placement plate 6, and the two symmetrical teeth with the farthest distance on the left and right are placed horizontally. At this time, the drive motor 18 can be started to work, thereby driving the drive gear 16 to rotate. Then, the rack 17 can drive the two movable bars 7 to move closer to each other, and finally push the gear to the center and stop. During the pushing process, the first gear 12 will contact the toothed bar 19. Under the action of the toothed bar 19, the first gear 12 drives the moving rod 11 to rotate. At this time, the spiral slide moves with the moving rod 11, thereby pushing the clamping plate 9 to move laterally through the slider, completing the clamping and fixing of the gear teeth, and further ensuring the stability of the gear processing.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
