A spring 9 and a spring 2 12 are respectively provided between the two sides of the two pistons 11 and the two sides of the corresponding guide hole 8. The inner centers of the two pistons 11 are fixedly connected to a connecting rod 13, and the ends of the connecting rod 13 are respectively connected to the corresponding The slide seat 16 is fixedly connected; the connecting seat 15 is longitudinally fixedly connected to the center of the bottom of the mounting seat 2, and the left and right sides of the connecting seat 15 are movably connected to the inside with a guide column 16, and the bottom of the guide column 16 is respectively fixedly connected to the left and right sides of the top of the connecting plate 18, and the bottom of the connecting plate 18 is fixedly connected to a number of suction cups 17; there are several oil cylinders 19, and several of the oil cylinders 19 are longitudinally arranged and fixedly connected to the center of the connecting seat 15, and the lower side piston rod ends of several of the oil cylinders 19 are fixedly connected to the center of the top of the connecting plate 18.

[0019] like Figure 2As shown, the specific structure of the adaptive clamping mechanism 10 includes an outer shell 101, an oil chamber 102, a connecting hole 103, a spring three 104, a slide rod 105 and a clamping block 106; there are several oil chambers 102, and several of the oil chambers 102 are arranged longitudinally and arranged inside the outer shell 101, and the left sides of several of the oil chambers 102 are connected through the connecting hole 103; there are several slide rods 105, and the left sides of several of the slide rods 105 are movably connected to the corresponding oil chambers 102, and a spring three 104 is provided between the left step surface of several of the slide rods 105 and the right side of the corresponding oil chamber 102, and the right ends of several of the slide rods 105 are fixedly connected to the clamping block 106.

[0020] The left side of the sliding rod 105 is T-shaped.

[0021] like Figure 3 As shown, the specific structure of the auxiliary adsorption mechanism 14 includes a connecting seat 141, a guide column 142, a connecting plate 143, a suction cup 144 and a cylinder 145; the guide columns 142 are movably connected to the inside of both sides of the connecting seat 141, and the bottom of the guide columns 142 are fixedly connected to the two sides of the top surface of the connecting plate 143; the oil cylinder 145 is fixedly connected to the inside of both sides of the center of the connecting seat 141, and the lower piston rod end of the oil cylinder 145 is fixedly connected to the top surface of the connecting plate 143; several suction cups 144 are fixedly connected to the bottom surface of the connecting plate 143.

[0022] The motor 3 is a servo motor and a stepper motor, which can accurately control the rotation of the output shaft.

[0023] When the pressing part is needed to be clamped, the robot arm 1 drives the entire clamping tool to move to the position of the pressing part, and the motor 3 is started. Since the motor 3 is a servo motor or a stepping motor, it can accurately control the rotation of the output shaft, and the output shafts on the left and right sides of the motor 3 drive the two screws 5 with opposite screw threads to rotate, so that the two slides 2 7 are close to or away from each other in the guide groove 4 on the bottom surface of the mounting seat 2, and the adaptive clamping mechanism 10 at the bottom of the slide 2 7 moves accordingly, ready to clamp the stamping part, and the outer shell 101 in the adaptive clamping mechanism 10 moves with the slide 2 7. When the clamping block 106 contacts the stamping part, the slide rod 105 moves to the left, and the hydraulic oil in the oil chamber 102 flows through the connecting hole 103, so that each slide rod 105 can adaptively adjust its position according to the shape of the stamping part, ensuring that the clamping block 106 can fit closely to the surface of the stamping part, thereby realizing the stamping part When the clamping surface is uneven, the need for clamping is met. At the same time, the slide 1 6 inside the slide 2 7 will also adjust its position in the guide groove 4 as the slide 2 7 moves. When the slide 1 6 is subjected to external force, the connecting rod 13 pushes the piston 11 to move in the guide hole 8 inside the lower side of the slide 2 7, compressing the spring 1 9 or the spring 2 12 to play a role in buffering and adjusting the position, thereby ensuring that the auxiliary adsorption mechanism 14 will not affect the clamping of the stamping part after working. The auxiliary adsorption mechanism 14 also plays a role in working. The oil cylinder 145 on the connecting seat 141 pushes the connecting plate 143 to move downward along the guide column 142, so that the several suction cups 144 at the bottom of the connecting plate 143 are tightly adsorbed on the surface of the stamping part, thereby enhancing the stability of clamping. In addition, the several oil cylinders 19 in the connecting seat 15 at the bottom center of the mounting seat 2 push the connecting plate 18 to move downward along the guide column 16, thereby making the several suction cups 17 at the bottom of the connecting plate 18 adsorbed on the surface of the stamping part, thereby further improving the reliability of clamping.
