In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0022] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] refer to Figure 1 , Figure 2 and Figure 3 , a flange loading and unloading clamping tool provided by the utility model, which can not only load and unload flange rolls, but also load and unload flange sheets; specifically, it includes a mechanical arm 1 and a grasping assembly 2 connected to the mechanical arm 1, the grasping assembly 2 includes a connecting plate 21 connected to the mechanical arm 1 and a grasping member Ⅰ22 and a grasping member Ⅱ23 respectively arranged on the lower end surface of the connecting plate 21, the grasping member Ⅰ22 and the grasping member Ⅱ23 are arranged relatively along the length direction of the connecting plate 21, and the grasping member Ⅰ22 and the grasping member Ⅱ23 both include an electromagnetic suction block 221 and a connecting member 222 for mounting the electromagnetic suction block 221 on the connecting plate. The suction area in the electromagnetic suction block 221 is located on the lower end surface of the electromagnetic suction block 221 in the axial direction, wherein the maximum spacing between the suction areas in the two electromagnetic suction blocks 221 is the same as the outer diameter of the flange, and the minimum spacing between the suction areas in the two electromagnetic suction blocks 221 is less than or equal to the inner diameter of the flange. When loading and unloading the flange, the mechanical arm 1 drives the electromagnetic suction block 221 in the grasping assembly 2 to move to the top of the flange and the lower end face of the electromagnetic suction block 221 is pressed against the upper end face of the flange. At this time, the electromagnetic suction block 221 is energized and magnetized to grasp the flange. When grasping the flange, two electromagnetic suction blocks 221 simultaneously absorb one flange, thereby improving the firmness of the flange when being absorbed. The electromagnetic suction block 221 adopts an electromagnet.

[0024] refer to Figure 2 , Figure 3 and Figure 4The connecting member 222 includes a fixed base 2221 and a mounting plate 2222 disposed on the fixed base 2221. The electromagnetic suction block 221 is mounted on the fixed base 2221. The mounting plate 2222 is provided with a locking bolt 2223 connected to the connecting plate 21. The connecting plate 21 is evenly provided with a plurality of position adjustment through holes 4 that cooperate with the locking bolts 2223 along its length direction. The positions of the clamping member I 22 and the clamping member II 23 on the connecting plate 21 can be adjusted by the cooperation of the locking bolts 2223 and the position adjustment through holes 4, thereby adjusting the spacing between the suction areas in the two electromagnetic suction blocks 221, so that the flange loading and unloading clamping tooling can grasp flanges of different models. The upper end surface of the mounting plate 2222 is provided with a sliding block 5, and the lower end surface of the connecting plate 21 is provided with a limiting guide rail 6 that cooperates with the sliding block 5. When adjusting the positions of the clamping member I22 and the clamping member II23 on the connecting plate 21, the sliding block 5 cooperates with the limiting guide rail 6 to play a guiding role, ensuring that the clamping member I22 and the clamping member II23 are located on the same straight line. In this example, the clamping member I22 is a dynamic clamping member, and the clamping member II23 is a fixed clamping member; there are four locking bolts 2223 in the clamping member II23 and they are distributed at the four corners of the mounting plate 2222, and the connecting plate 21 is provided with locking holes 7 that cooperate with the locking bolts 2223 in the clamping member II23.

[0025] refer to Figure 2 , Figure 3 and Figure 4 A stepped surface 8 is provided on the upper end surface of the mounting plate 2222 at a position corresponding to the sliding block 5, and the bottom end of the sliding block 5 abuts against the vertical surface of the stepped surface 8, so that the sliding block 5 is limited by the stepped surface 8 to prevent the sliding block 5 from moving.

[0026] refer to Figure 2 , Figure 3 and Figure 4 , the clamping member I22 and the clamping member II23 also include a position detector 9, which is fixed on the mounting plate 2223 through the support rod 10 and is located at the front end of the electromagnetic suction block 221. The position detector 9 is used to detect whether the electromagnetic suction block 221 is located on the upper end surface of the flange. When the position detector 9 detects that the electromagnetic suction block 221 is located above the flange, the position detector 9 transmits the detected signal to the external control component, and controls the mechanical arm 1 to make the electromagnetic suction block 221 contact the flange through the control component, and also controls the electromagnetic suction block 221 to be energized and magnetized through the control component, so as to achieve the adsorption of the flange. By arranging the position detector 9 on both the clamping member I22 and the clamping member II23, when both position detectors 9 detect that the corresponding electromagnetic suction block 221 is located above the flange, the signal can be transmitted to the control component, so that the mechanical arm 1 can be controlled to work and the electromagnetic suction block 221 can be energized and magnetized through the control component, so as to improve the firmness of the flange loading and unloading clamping tooling when grasping the material.

[0027] To sum up: when the flange is grabbed by the flange loading and unloading clamping tooling of this structure, the flange is adsorbed by the electromagnetic suction block. When the grabbed flange is moved by the robotic arm, the grabbing component adsorbs the flange more firmly, and the flange is not likely to fall off, thereby improving safety at work and reducing safety hazards. In addition, this clamping tooling has a simple structure, is easy to process and manufacture, and has a low production cost.

[0028] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
