Step five, the burr detector 32 detects the cutting quality of the pin, and judges whether the cutter 28 needs to be replaced according to the detection result, if the cutter 28 needs to be replaced, the mechanical arm 6 drives the cutting structure to move until the cutter 28 to be replaced is inserted into the cutter slot 20, the hydraulic telescopic rod six 16 drives the moving plate two 17 to move, the moving plate two 17 drives the rotating motor two 18 fixedly connected with the moving plate two 18 to move, the rotating motor two 18 drives the screwdriver 19 fixedly connected with the rotating motor two 18 to move until the screwdriver 19 is in contact with the bolt 31, the rotating motor two 18 drives the screwdriver 19 to rotate, the screwdriver 19 can screw the bolt 31, the screwdriver 19 continues to stretch in the rotating process, the screwdriver 19 drives the bolt 31 to move until the bolt 31 is separated from the moving rod one 30, the cutter 28 to be replaced is detached, the mechanical arm 6 drives the moving rod one 30 to be separated from the cutter 28 until the moving rod one 30 is aligned with a new cutter 28, and the hydraulic telescopic rod six 16 and the hydraulic telescopic rod five 14 are matched to use in the moving process until the screwdriver 19 is automatically replaced by the new cutter 28, and the cutter 19 is connected with the new cutter 28 by the new cutter slot 28.
Standard parts used in the present invention can be purchased from the market, the special-shaped parts can be customized according to the descriptions of the specification and the drawings, the specific connection modes of the parts are conventional means such as bolts, rivets, welding and the like which are mature in the prior art, and the machines, the parts and the equipment are conventional models in the prior art, so that details which are not described in detail in the specification belong to the prior art which is well known to the person skilled in the art, and although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and equivalents thereof.
