Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1: Please refer to Figures 1-4 A gear clamping device for gearbox components includes a chuck 1, a central post 12 through which the chuck 1 is installed, a circular groove 13 on the front end face of the central post 12, an installation groove 15 on the rear end face of the central post 12, a connecting hole 16 through which the circular groove 13 and the installation groove 15 are provided, a sliding groove 11 on the outer surface of the chuck 1 and on the outer side of the central post 12, a rear groove 14 on the rear end of the sliding groove 11 and on the outer surface of the chuck 1, a positioning member 4 slidably installed inside the sliding groove 11 and the rear groove 14, and a positioning member 4 is also installed inside the circular groove 13, the installation groove 15 and the connecting hole 16.
[0023] The positioning component 4 includes an outer sliding block 41 and an internally threaded tube 42 disposed at the rear end of the outer sliding block 41. A square moving block 43 is installed at one end of the internally threaded tube 42. A connecting bolt 44 is installed between the square moving block 43, the internally threaded tube 42 and the interior of the outer sliding block 41. The square moving block 43 is slidably installed inside the rear groove 14, and the internally threaded tube 42 is slidably installed inside the slide groove 11.
[0024] A positioning vertical groove 46 is provided at the middle end of the outer sliding block 41. An inner frame 47 is horizontally installed inside the positioning vertical groove 46. A cylinder 48 is installed inside the inner frame 47. A moving plate 49 is installed at the moving end of the cylinder 48. Inner moving strips 462 are symmetrically installed at the upper and lower ends inside the positioning vertical groove 46. An inclined plate 461 is installed at one end of the inner moving strip 462. When the cylinder 48 extends or retracts, the position of the rotating groove 491 and the rotating plate 492 can be adjusted by the moving plate 49.
[0025] The top and bottom of the movable plate 49 are provided with rotating grooves 491. A rotating plate 492 is installed inside the rotating grooves 491. A cross groove 463 is provided on the side of the two sets of inclined plates 461 that are close to each other. Movable rods 493 are installed at both ends of the rotating plate 492. The movable rods 493 are slidably installed on both sides inside the cross grooves 463. The rotating plate 492 and the movable rods 493 can be used to keep the movable plate 49 and the inclined plates 461 moving synchronously.
[0026] A fixed slide rod 464 is vertically installed inside the positioning groove 46, and the upper end of the fixed slide rod 464 is installed through the middle of the inner frame 47. The inner moving strip 462 is slidably installed on the outer surface of the fixed slide rod 464.
[0027] The outer surface of the chuck 1 and both sides of the slide groove 11 are provided with mounting threaded holes 2. The slide groove 11 has four sets, and the positioning bolts 3 have five sets. The four sets of positioning bolts 3 are respectively installed inside the four sets of slide grooves 11, and the components are clamped from the outside by the four sets of positioning components 4.
[0028] In this embodiment: when clamping the component from the outside, rotating the positioning bolt 3 causes the threaded end of the positioning bolt 3 to move out of the mounting threaded hole 2, allowing the outer sliding block 41 to rotate 90°, changing the placement angle of the inclined surface 461 from the horizontal to the vertical direction. This pushes the positioning component 4 to move within the slide groove 11 and the rear groove 14, while the square moving block 43 moves to a limited position within the rear groove 14. The internal threaded tube 42 moves within the slide groove 11. When the symmetrical inclined surface 461 moves into the outer slot of the component, the cylinder 48 extends, and the moving plate 49 moves away from the positioning vertical groove 46. The movable plate 49 drives the movable rod 493 to move inside the cross groove 463 via the rotating plate 492. Since the two sets of inner moving strips 462 are far apart on the side closer to the outer sliding block 41, when the movable plate 49 moves away from the outer sliding block 41, it can pull the two sets of inner moving strips 462 away. One end of the two sets of inclined plates 461 opens from the inside of the slot to clamp and fix the parts from the outside. After the positioning threaded hole 45 is aligned with the mounting threaded hole 2, the positioning bolt 3 is threaded into the inside of the mounting threaded hole 2 to fix the position of the outer sliding block 41 after rotation, which is convenient for processing the parts.
[0029] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 The outer sliding block 41 has a positioning threaded hole 45 on its outer side. A set of four sets of positioning threaded holes 45 are provided on the outer side of the outer sliding block 41. The positioning threaded hole 45 is internally threaded with a positioning bolt 3. The positioning bolt 3 is used to install the outer sliding block 41 between the chuck 1.
[0030] In this embodiment: an internally threaded tube 42 and an externally sliding block 41 are inserted into the inside of the circular groove 13. The internally threaded tube 42 is inserted into the inside of the connecting hole 16. The externally sliding block 41 is moved into the inside of the circular groove 13. The square moving block 43 is inserted into the inside of the mounting groove 15. The rear end of the square moving block 43 is threaded into the inside of the square moving block 43, the internally threaded tube 42, and the externally sliding block 41. The positioning component 4 is assembled using the connecting bolt 44. When clamping and fixing the component from the inside, the two sets of inclined plates 461 first move closer together, and the middle end of the component is sleeved on the outside of the moving plate 49. The cylinder 48 extends, and the two sets of inclined plates 461 move away from each other. The outer side of the inclined plate 461 contacts the inner wall of the component. The inclined plate 461 is used to fix the component from the inside.
[0031] Working principle: When clamping the parts from the outside, the positioning component 4 is pushed to move inside the slide groove 11 and the rear groove 14. After the symmetrical inclined nipple 461 moves into the outer slot of the parts, the cylinder 48 extends and the moving plate 49 moves away from the positioning vertical groove 46. One end of the two sets of inclined nipple 461 opens from the inside of the slot to clamp and fix the parts from the outside. When clamping and fixing the parts from the inside, the two sets of inclined nipple 461 first move closer and fit the middle end of the parts onto the outside of the moving plate 49. The cylinder 48 extends and the outer side of the inclined nipple 461 contacts the inner wall of the parts. The inclined nipple 461 is used to fix the parts from the inside.
