[0027] A downward pressing and fastening mechanism includes a driving connection assembly arranged at the middle position of the lower surface of the clamping claw 107, and a downward pressing and fastening assembly is arranged at the end of the driving connection assembly. When the multi-axis robot body 100 is running, after the clamping claw 107 clamps and fixes the workpiece, the downward pressing and fastening mechanism presses and fixes the upper surface of the workpiece, so as to facilitate more stable clamping and transfer of the workpiece, and prevent it from falling off during clamping, thereby improving the fixity of the multi-axis robot body 100 in clamping the workpiece during cutting and processing operations.

[0030] Working principle and use process of the utility model: When using this kind of cutting processing multi-axis robot, firstly, the multi-axis robot body 100 is placed at the cutting processing production position through the base 101, and the fixing bolts are screwed into the inside of the mounting hole 102 to fix the base 101. After fixing, the multi-axis robot body 100 is driven to operate, and the clamping claw 107 rotates to the direction of clamping the workpiece, and the clamping claw 107 clamps the workpiece to be cut and transfers it to the cutting position;

[0031] Then, before the multi-axis robot body 100 is used, the fixing bolts are rotated and fixed to the base 101 in the installation position inside the installation hole 102, and the support reinforcement rod 1014 is slid open again in the internal limit position of the limit moving groove 1013 until the fixing plate 1012 is completely opened to the external installation position, and the support reinforcement rod 1014 is fixed by rotating the reinforcement bolts 1015 inside the groove 1011, and the fixing plate 1012 is fixed to the installation position by rotating the fixing bolts inside the installation hole 1016 again. After the base 101 is fixed and installed, it is reinforced and installed by the support reinforcement rod 1014 and the fixing plate 1012, and the multi-axis robot body 100 is reinforced and installed. Therefore, the multi-axis robot body 100 is more stable when the workpiece is transferred during regular cutting and processing operations, and it is not easy to cause the fixing bolts to loosen and fall off, thereby improving the fixity of the installation and the stability of use of the multi-axis robot body 100 during cutting and processing operations;

[0032] Finally, when the multi-axis robot body 100 operates the clamping claw 107 to clamp and fix the workpiece for transfer, after the clamping claw 107 clamps the workpiece, the cylinder 1071 is operated again to drive the mounting plate 1072 and the supporting connecting rod 1073 to press down until the lower pressure plate 1074 is pressed down to make the flexible plate 1075 contact the surface of the clamped workpiece, and the flexible plate 1075 is deformed to strengthen the pressure on the upper surface of the workpiece. At the same time, the flexible plate 1075 is deformed to press down and fix the irregular workpiece. Therefore, after the clamping claw 107 clamps and fixes the workpiece, the lower pressure plate 1074 and the flexible plate 1075 are pressed down to press the upper surface of the workpiece, which facilitates more stable clamping and transfer of the workpiece, and is not easy to fall during clamping, thereby improving the fixity of the multi-axis robot body 100 in the cutting and processing operation to transfer the workpiece.
