Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-4 As shown, a hydraulic three-axis manipulator comprises a hydraulic three-axis manipulator body 1, and a clamping mechanism 21 is arranged on the hydraulic three-axis manipulator body 1, and the clamping mechanism 21 comprises a connecting box 211, and a partition 212 is fixedly installed inside the connecting box 211, and a slide groove 213 is provided at the bottom of the partition 212, and a motor 214 is fixedly installed on one side of the inner wall of the slide groove 213, and a bidirectional screw 215 is fixedly connected to the output end of the motor 214, and the other end of the bidirectional screw 215 is rotatably connected to the other side of the inner wall of the slide groove 213 through a bearing, and a clamping block 216 is slidably connected to the inner wall of the slide groove 213, and the clamping block 216 is threadedly sleeved on the outer wall of the bidirectional screw 215, and the bidirectional screw 215 rotates, so that the clamping block 216 threadedly sleeved on the outer wall of the bidirectional screw 215 moves, and a mounting plate 6 is fixedly installed on the top of the connecting box 211, and the connecting box 211 and other components are mounted on the hydraulic three-axis manipulator body 1 through the mounting plate 6, and a positioning hole is provided on the mounting plate 6.

[0023] Specifically, when it is necessary to clamp small pieces of material, the motor 214 can be started so that the output end of the motor 214 drives the fixedly connected bidirectional screw 215 to rotate, thereby causing the clamping block 216 threadedly sleeved on the outer wall of the bidirectional screw 215 to move, and the clamping block 216 slides on the inner wall of the slide groove 213, and the two clamping blocks 216 approach each other, so that the small piece of material can be clamped and fixed for subsequent operations.

[0024] like Figure 3-4 As shown, a fixing mechanism 31 is also provided on the inner wall of the connection box 211, and the fixing mechanism 31 includes a piston cylinder 311, which is fixedly installed at the bottom of the inner wall of the connection box 211, and a piston head 312 is slidably connected to the inner wall of the piston cylinder 311. The fixing mechanism 31 also includes a suction cup 313, which is fixedly installed at the bottom of the connection box 211 and is connected to the piston cylinder 311. The suction cup 313 can adsorb large materials, and a pull rod 314 is fixedly installed on the top of the piston head 312. An electric push rod 4 is also provided on the inner wall of the connection box 211, and the electric push rod 4 is fixedly installed on the top of the inner wall of the connection box 211. The top of the pull rod 314 passes through the partition 212 and is fixedly installed with a lifting plate 5. The inner rod of the electric push rod 4 drives the lifting plate 5 to rise, thereby driving the pull rod 314 fixedly connected to the bottom of the lifting plate 5 to rise, and the top of the lifting plate 5 is fixedly connected to the inner rod of the electric push rod 4.

[0025] Specifically, when it is necessary to clamp large materials, the electric push rod 4 can be started so that the inner rod of the electric push rod 4 drives the lifting plate 5 to rise, thereby driving the pull rod 314 fixedly connected to the bottom of the lifting plate 5 to rise, so that the piston head 312 fixedly connected to the bottom of the pull rod 314 rises on the inner wall of the piston cylinder 311, and then the inside of the piston cylinder 311 can be negative pressure, and the suction cup 313 can absorb the large materials.

[0027] The working principle of the utility model is as follows:

[0028] The hydraulic three-axis manipulator body 1 adopts gears and racks for transmission and lifting. Compared with the screw transmission, the transmission speed is faster, and the subsequent maintenance and replacement of the rack is also simpler and more efficient. The screw usually requires complex debugging and leveling. The connecting box 211 and other components are installed on the hydraulic three-axis manipulator body 1 through the mounting plate 6. When it is necessary to clamp small materials, the motor 214 can be started so that the output end of the motor 214 drives the fixedly connected bidirectional screw 215 to rotate, so that the clamping block 216 with a threaded sleeve on the outer wall of the bidirectional screw 215 moves, and the clamping block 216 slides on the inner wall of the slide groove 213, and the two clamping blocks 216 move against each other. When the lifting plate 5 is lifted up, the lifting plate 5 is lifted up, thereby the pull rod 314 fixedly connected to the bottom of the lifting plate 5 is lifted up, so that the piston head 312 fixedly connected to the bottom of the pull rod 314 is lifted up on the inner wall of the piston cylinder 311, and then the inside of the piston cylinder 311 is negatively pressurized, and the suction cup 313 can absorb the large material, and finally cooperate with the clamping mechanism 21, so that the large material can be clamped and fixed, so as to facilitate the subsequent operation of the oil hydraulic three-axis manipulator body 1.
