In order to prevent the pressing block 11 from crushing the special-shaped material, the elastic element is preferably a spring.

[0032] In one embodiment of the present invention, referring to Figure 3 As shown, the first claw 7 is provided with a first limit block 72, the second claw 8 is provided with a first limit block 82, and the front of the first limit block 82 is provided with a first abutting surface 83. When the first abutting surfaces of the first claw 7 and the second claw 8 abut against the special-shaped material, the special-shaped material can be prevented from rotating; the first notch 73 and the second notch 87 are both located on the side of the first limit block, and the first limit block 72 of the first claw 7 is arranged opposite to the first limit block 82 of the second claw 8.

[0033] In one embodiment of the present invention, referring to Figure 3As shown, the first claw 7 is provided with a second limit block 71, and the second claw 8 is also provided with a second limit block 81. The first limit block 71 and the second limit block 81 are arranged opposite to each other, and the front of the second limit block 82 is provided with a second abutting surface. The second limit block 71 of the first claw 7 is arranged opposite to the second limit block 81 of the second claw 8, wherein a first clamping gap 74 is provided between the first abutting surface and the second abutting surface of the first claw 7, and a second clamping gap 88 is provided between the first abutting surface 83 and the second abutting surface of the second claw 8, and the first clamping gap 74 is arranged opposite to the second clamping gap 88, and the middle part of the special-shaped material is inserted into the first clamping gap 74 and the second clamping gap 88 to play a limiting role.

The six-sided pressure sensor 2 is arranged on the small surface of the base 1 relative to the clamping claw assembly. The six-sided pressure sensor 2 detects the reaction force exerted on the pressing block 11.

[0036] In one embodiment of the present invention, referring to Figure 3 As shown, the edges of the first notch 73 and the second notch 87 are both provided with an avoidance slope 84, and the avoidance slope 84 is used to reduce the thickness of the first notch 73 and the second notch 87, so that the second guide surface 86 is relatively slender, which is conducive to the sliding of special-shaped materials.

[0037] The working principle of the special-shaped material fastening device of the utility model is:

[0038] The special-shaped material fastening device is installed in the manipulator, and the middle part of the special-shaped material is manually inserted into the first clamping gap 74 and the second clamping gap 88, and the two ends of the special-shaped material are respectively against the first notch 73 and the second notch 87, and then the first driver 6 drives the first claw 7 and the second claw 8 to open the two ends of the special-shaped material. Under the pulling force of the first claw 7 and the second claw 8, if the special-shaped material is in a non-parallel state, the two ends of the special-shaped material will slide relatively to the first guide surface 85 and the second guide surface 86 until they are located at the bottom of the first notch 73 and the second notch 87. At this time, the two ends of the special-shaped material are in another balanced state. At this time, the two ends of the special-shaped material are at the same height, that is, in a parallel state. After that, the manipulator moves the special-shaped material fastening device to the top of the assembly station, and the first claw 7 and the second claw 8 insert the two ends of the special-shaped material into the surface of another component respectively and then slightly approach, and then the second driver 10 drives the pressing block 11 to extend to fasten the special-shaped material and press it into the component to complete the interference assembly.
