[0022] It also includes: a lifting block 6, a moving block 7, a rotating seat 8, a pressing block 9 and two clamping blocks 10;
[0023] like Figures 1 to 3When the chamfering knife 5 moves to the required position, the motor 23 fixedly connected to the rotating seat 8 is started, and the output shaft of the motor 23 is threadedly connected to the bidirectional lead screw 24 rotatably connected to the rotating seat 8, so the motor 23 will drive the bidirectional lead screw 24 to rotate, and the bidirectional lead screw 24 drives the clamping block 10 relatively slidably connected to the upper end of the rotating seat 8 to clamp the pin. After the pin is clamped, the electric push rod 25 fixedly connected to the lifting block 6 is started, and the electric push rod 25 is used to drive the moving block 7 fixed to its output shaft to move, and the moving block 7 drives the rotating seat 8 rotatably connected to the moving block 7 to move, thereby realizing that the clamping block 10 drives the pin shaft to move to the position where the chamfering knife 5 is connected to the chamfering knife 5 are arranged relatively, the electric push rod 26 fixedly connected to the base 1 is started, and the output shaft of the electric push rod 26 is fixedly connected to the lifting block 6, so the electric push rod 26 drives the lifting block 6 to assist in driving the pin shaft to move to be close to the chamfering knife 5, the motor 3 27 fixedly connected to the rotating disk 3 is started, and the output shaft of the motor 3 27 is fixedly connected to the rotating block 4, so the motor 3 27 drives the rotating block 4 to rotate, and then the rotating block 4 drives the chamfering knife 5 to chamfer the pin shaft, and after the chamfering of the pin shaft is completed, the motor 4 28 fixedly connected in the moving block 7 is started, and the output shaft of the motor 4 28 is fixedly connected to the rotating seat 8, so the motor 4 28 will drive the rotating seat 8 to rotate, so that the rotating seat 8 assists in driving the pin shaft to rotate, thereby realizing the flipping of the pin shaft, and at the same time, in the process of chamfering the pin shaft, the electric push rod 3 29 fixedly connected to the bracket 2 is fixedly connected to the pressing block 9, and the electric push rod 3 29 drives the pressing block 9 to be close to the pin shaft, so as to prevent the pin shaft from moving on the clamping block 10 during the chamfering process.
[0024] like Figures 1 to 3When the pin shaft is in the process of chamfering, since the base 1 is driven to slide and connect with the moving seat 11, the moving seat 11 is driven to lift and connect with the sliding seat 12, the sliding seat 12 is fixedly connected with a dust suction frame 13 with a dust suction groove on the side wall, and the base 1 is fixedly connected with a dust collector 14 which is in communication with the dust suction groove, the electric push rod 4 30 fixedly connected to the base 1 is started, and the output shaft of the electric push rod 4 30 is fixedly connected to the moving seat 11, so the electric push rod 4 30 drives the moving seat 11 to move, and when the moving seat 11 moves to a certain position, the electric push rod 5 31 fixedly connected to the moving seat 11 is started, and the output shaft of the electric push rod 5 31 is fixedly connected to the sliding seat 12, so the electric push rod 5 31 drives the sliding seat 12 to drive the dust suction frame 13 close to the pin shaft, and at this time the dust collector 14 is started, and the chamfered dust will enter the dust collector 14 through the dust suction groove and the pipeline, thereby realizing the generation of dust.
