s3: and S2, after the step is finished, firstly loosening the clamping mechanism, then fixing the nut q to be machined through the secondary clamping mechanism, resetting the active feeding mechanism, rotating the nut q to be machined through a rotating mechanism by 180 degrees, finally moving the active feeding mechanism to be close to the clamping mechanism, starting the chamfering mechanism again to chamfer the rear end surface of the nut q to be machined, and finishing the inner side threads of the nut q to be machined through the tapping mechanism.

The working principle of the invention is as follows:

when the surface of the nut q to be processed is required to be chamfered, firstly, a chamfering motor 404 is started, a connecting rotating shaft 407 is driven to rotate by the chamfering motor 404, then a rotating disc 406 and a chamfering cutter 405 are driven to synchronously rotate, then a driving screw 402 is driven to rotate by a first driving motor 401, a first mounting plate 403 in threaded connection is adjusted to approach the nut q to be processed, so that the chamfering cutter 405 approaches the front end face of the nut q to be processed, and the front end face of the nut q to be processed is chamfered;

before machining, a nut q to be machined on the conveyor belt 3 is moved and placed on the surface of a moving base 803 which is matched with the shape of the nut q to be machined through an external manipulator, then a driving cylinder 804 is started to drive the moving base 803 to approach a positioning plate 9 until the moving base 803 is jointed with the positioning plate 9, chamfering is carried out after jointing, in the chamfering process, a limit column 409 on the surface of a rotating disc 406 which is close to the nut q to be machined is jacked to be jointed at the middle position of the front end surface of the nut q to be machined, and the nut q to be machined is limited not to move forwards, so that tapping is facilitated;

in the process that the moving base 803 is close to the positioning plate 9, the first limiting mechanism limits the rear end of the nut q to be processed, ejects one end distance from the front end of the nut q to be processed, reserves the chamfering position of the nut q to be processed, and is beneficial to the chamfering processing step;

in the initial state, the limiting plate 11 is influenced by the support of the first connecting spring 1103, is parallel to the inner side wall of the lower clamping block 901, does not block the movement of the nut q to be processed, and in the process that the moving base 803 is close to the positioning plate 9, the moving base 803 can squeeze the first jacking rod 12, and the first jacking rod 12 can squeeze the second connecting spring 1203 and approaches to the limiting plate 11 at the corresponding position;

the first inclined surface of the first ejector moving rod 12 can extrude the third inclined surface of the matched limiting plate 11, so that the limiting plate 11 stretches the first connecting spring 1103, stretches out of the inner side wall of the lower clamping block 901, and shields the moving path of the rear end of the nut q to be processed, so that after the moving base 803 and the nut q to be processed on the surface move to be close to the positioning plate 9, the front end of the nut q to be processed is pushed to be limited by the close limiting post 409, the rear end of the nut q to be processed is attached to the limiting plate 11, and at the moment, the front end of the nut q to be processed maintains a certain extending distance due to the limiting of the limiting plate 11 at the rear end, and the processing distance of the first chamfer is reserved;

similarly, when the positioning plate 9 is rotated 180 ° by the rotation mechanism, the moving base 803 moves closer to the positioning plate 9 again, at this time, the two nuts q to be processed are pushed by the two electric telescopic rods 14 to move to the front side position on the lower clamping block 901 again toward the front end, the moving base 803 presses the second pushing rod 13, and the second pushing rod 13 presses the third connecting spring 1303 and approaches to the limiting plate 11 at the corresponding position;

the second inclined plane of the second ejector pin 13 can extrude the fourth inclined plane of the identical limiting plate 11, so that the limiting plate 11 stretches the first connecting spring 1103 and stretches out of the inner side wall of the lower clamping block 901, the rear end moving path of the nut q to be processed is shielded, and thus after the front end of the nut q to be processed is pushed and limited by the adjacent limiting post 409, the rear end of the nut q to be processed can be attached to the limiting plate 11, and at the moment, the front end of the nut q to be processed maintains a certain distance due to the limiting of the limiting plate 11 at the rear end, and the processing distance of the second chamfer is reserved.

The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention, which is defined by the appended claims.
