[0035] Specifically, the rotary table 201 is fixedly connected to the top center of the workbench 1. The rotary table 201 is rotatably connected to a rotating shaft 202. The top end of the rotating shaft 202 extends to the upper outer side of the rotary table 201 and is fixedly connected to a turntable 203. A lifting plate 206 is movably connected above the turntable 203. Multiple insert rods 207 are fixedly connected to the end faces of the turntable 203 and the lifting plate 206 that are close to each other. The rotary table 201 is used to install the rotating shaft 202, the turntable 203 and other structures. The rotating shaft 202 is used to drive the turntable 203 to rotate. The turntable 203 and the lifting plate 206 are used to install the insert rods 207 and drive the insert rods 207 to rotate.

[0042] Specifically, two movable frames 301 are provided and movably connected to the two sides of the top rear end of the worktable 1. Lifting blocks 302 are movably connected inside each movable frame 301. A mounting shell 303 is fixedly connected between adjacent lifting blocks 302. A trimming blade 304 is fixedly connected to the front end face of the mounting shell 303 via an L-shaped plate 304a. A second drive motor 305b is fixedly connected inside the mounting shell 303 via a second motor frame 305a. The output shaft of the second drive motor 305b extends to the outer rear end of the mounting shell 303 and is fixedly connected to a grinding wheel 305. The movable frames 301 are designed to drive the trimming blade 304 and the grinding wheel 305 to perform linear motion in the front-back direction, thereby causing the trimming blade 304 or... The grinding wheel 305 contacts the rubber hose. The lifting block 302 is used to drive the trimming knife 304 and the grinding wheel 305 to move linearly up and down, so that the trimming knife 304 or the grinding wheel 305 trims the rubber hose. The mounting shell 303 is used to install the trimming knife 304 and the grinding wheel 305. The trimming knife 304 is used to cut and trim the rubber hose. The L-shaped plate 304a is used to fix the trimming knife 304 on the mounting shell 303. The grinding wheel 305 is used to grind and trim the rubber hose. The second motor frame 305a is used to install the second drive motor 305b. The second drive motor 305b is used to drive the grinding wheel 305 to rotate.

[0043] Furthermore, a first mounting plate 301a is fixedly connected to the rear end face of the workbench 1, and a second mounting plate 301b is fixedly connected to the top rear end of the workbench 1. Slide rods 301c are fixedly connected to both sides of the first mounting plate 301a and the second mounting plate 301b. The bottoms of the two movable frames 301 are respectively slidably sleeved on the outer walls of the two slide rods 301c.

[0044] The rear end face of the first mounting plate 301a is fixedly connected to the first hydraulic cylinder 301d. The output shaft of the first hydraulic cylinder 301d extends to the front end of the first mounting plate 301a and is fixedly connected to the moving block 301e. The outer walls on both sides of the moving block 301e are respectively fixedly connected to the lower outer walls of the two movable frames 301 that are close to each other.

[0045] The top of the movable frame 301 is fixedly connected to a second hydraulic cylinder 302a. The output shaft of the second hydraulic cylinder 302a extends to the inside of the movable frame 301 and is fixedly connected to the top of the lifting block 302. The front and rear end faces of the lifting block 302 are attached to the inner wall of the movable frame 301.

[0046] U-shaped plates 303a are fixedly connected to both outer walls of the mounting housing 303. A second fixing rod 303b is fixedly connected to the vertical support arm of the U-shaped plate 303a.

[0048] The operation process of this embodiment is as follows: The first hydraulic cylinder 301d is started, which causes the movable frame 301 to move the mounting shell 303, thereby making the trimming knife 304 contact the rubber hose. The trimming knife 304 is then raised and lowered by the lifting block 302, which cuts and trims the rubber hose. Then, the first hydraulic cylinder 301d is started again, which separates the trimming knife 304 from the rubber hose and loosens the second fastening nut 303c. At the same time, the mounting shell 303 is rotated by the second fixing rod 303b, which makes the grinding wheel 305 contact the rubber hose. After tightening the second fastening nut 303c, the second drive motor 305b is started. The output shaft of the second drive motor 305b drives the grinding wheel 305 to grind and trim the rubber hose.
