Furthermore, the hydraulically driven extension and retraction have a large impact, leading to poor machining stability, which in turn affects machining accuracy and tool life.

[0004] Therefore, it is necessary to design a hydraulically controlled high-precision broach to solve the above problems. Utility Model Content

[0019] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figure 1-3This utility model provides a hydraulically controlled high-precision broach, including a worktable 1. A through hole is formed on the outer surface of the worktable 1. A clamping mechanism is provided on the top of the worktable 1. An I-shaped guide rail 9 is fixedly connected to the top of the worktable 1. Water tanks 6 are fixedly connected to both ends of the I-shaped guide rail 9. Two symmetrical guide rail sleeves 10 are slidably engaged on the top of the I-shaped guide rail 9. An L-shaped plate 2 is fixedly connected to one side of the worktable 1. A servo hydraulic cylinder 3 is fixedly inserted into the top of the L-shaped plate 2. A clamping head 21 is fixedly connected to the bottom end of the servo hydraulic cylinder 3, and the clamping head 21 is located directly above the through hole. In this configuration, a fixed sleeve block 4 is fixedly sleeved on the clamping head 21. Rotating blocks 5 are rotatably connected inside each of the two guide rail sleeve blocks 10, and the other ends of the two rotating blocks 5 are symmetrically rotatably connected to one side of the fixed sleeve block 4. Connecting posts 13 are fixedly connected to the opposite sides of the two guide rail sleeve blocks 10. Sealing sleeves 11 are fixedly sleeved on the outer surfaces of the two connecting posts 13. A honeycomb plate 12 is fixedly connected to one end of the connecting post 13 and the sealing sleeve 11 on the same side. A cylindrical groove is formed inside the water tank 6, and the honeycomb plate 12 is slidably disposed inside the cylindrical groove. The connecting column 13 and the sealing sleeve 11 are slidably inserted into the corresponding water tank 6. When the broach is clamped on the clamping head 21, the component placed on the top of the worktable 1 is broached by the hydraulic extension and retraction of the servo hydraulic cylinder 3. The through hole facilitates the passage of the broach. During the entire processing, the lifting and lowering of the clamping head 21 will drive the two rotating blocks 5 to rotate. The bottom ends of the two rotating blocks 5 will push the two guide rail blocks 10 to slide horizontally on both sides of the I-shaped guide rail 9, thereby preventing the broach from shaking and causing broaching deviation when the broach is broaching back and forth. At the same time, through the two The water tank 6 is filled with water. When the two guide rail blocks 10 slide, the two sealing sleeves 11 and the two connecting columns 13 push the two honeycomb plates 12 to slide inside the two cylindrical grooves respectively. The honeycomb holes of the two honeycomb plates 12 push the water source to perform a certain buffering work, which improves the stability of the servo hydraulic cylinder 3 driving the broach extension and retraction. The two sealing sleeves 11 improve the sealing of the water tank 6.

One end of the bidirectional threaded rod 23 is fixedly connected to a knob 16.

[0023] When the two rotating blocks 5 rotate, the sliding insertion of the insertion post 19 inside the insertion cylinder 18 improves the rotational stability of the two rotating blocks 5. One side of each of the two rotating blocks 5 is rotatably connected to a rotating shaft 17, and the insertion cylinder 18 and the insertion post 19 are rotatably and fixedly inserted inside the two rotating shafts 17. The insertion post 19 is slidably inserted inside the insertion cylinder 18, and one end of the insertion post 19 is fixedly connected to a limit block 20.
