As a further scheme of the invention, the elastic trend of the elastic telescopic rods I4-4, the elastic telescopic rods II 4-8, the elastic telescopic rods IV 4-11 and the elastic telescopic rods V7-2 is outward expansion, and the elastic trend of the elastic telescopic rods III 4-9 is inward contraction.
The working principle is as follows: before the operation, (as shown in figure 1) the extrusion ring 3-1 is pressed downwards, then the standard component 1-2 is placed on the extrusion ring 3-1 (the chamfer to be processed is upward), then the limitation on the extrusion ring 3-1 is removed, at the moment, the extrusion ring 3-1 pushes the standard component 1-2 to move upwards under the action of the spring 3-2 (in the process, the wedge-shaped plate I4-7 and the wedge-shaped plate II 4-13 play a guiding role, the standard component 1-2 pushes the wedge surfaces of the wedge-shaped plate I4-7 and the wedge-shaped plate II 4-13 through the extrusion of the wedge surfaces, so as to further expand the elastic telescopic rod I4-4 and contract the elastic telescopic rod IV 4-11), after the standard component 1-2 enters the slide rod I4-6 and the slide rod II 4-10 to reach the lower end of the adjusting rod 4-5, the connecting block 4-1 above and below the adjusting rod 4-5 is extruded, further expanding the first elastic telescopic rod 4-4 and the fourth elastic telescopic rod 4-11, further changing the angle of the adjusting rod 4-5 until the adjusting rod 4-5 is aligned with the chamfer on the standard part 1-2, and then expanding the first elastic telescopic rod 4-4 and the fourth elastic telescopic rod 4-11 in a mode that the side face of the adjusting rod 4-5 is extruded by the chamfer inclined face if the standard part 1-2 moves upwards continuously, wherein the mode is very labor-consuming, and the spring 3-2 cannot provide the pushing force for the standard part 1-2 to move upwards continuously after the standard part 1-2 is in place (along with the pushing of the spring 3-2, the compression amount of the spring 3-2 is reduced, further the pushing force is reduced, so that the spring 3-2 cannot provide the pushing force for the standard part 1-2 to move upwards after the spring 3-2 meets the pushing force for expanding the slide rod);
in the process of changing the angle of the adjusting rod 4-5 (as shown in figure 4), the adjusting rod 4-5 corresponding to the chamfer angle at the outer side of the friction plate 1 takes the left end as an example, because the right end of the elastic expansion link I4-4 is vertically and fixedly connected with the connecting rod 4-12, the left end of the elastic expansion link I4-4 is connected with the sliding rod I4-6 in a sliding way, so that the slide bar I4-6 is parallel to the elastic telescopic link I4-4, and because the distances between the two ends of the cutter 4-2 and the adjusting rod 4-5 and the rotary connection positions of the slide bar I4-6 and the elastic telescopic link I4-4 are equal, the cutter 4-2, the adjusting rod 4-5, the slide bar I4-6 and the elastic telescopic link I4-4 form an isosceles trapezoid, further, the angle of the adjusting rod 4-5 and the angle of the cutter 4-2 are symmetrical about the horizontal plane; (as shown in FIG. 3) the relation between the adjusting rod 4-5 corresponding to the inner chamfer of the friction plate 1 and the cutter 4-2 is also symmetrical about the horizontal plane; further, the cutter 4-2 copies the inclination of the chamfer on the standard component 1-2 in the above manner;
(fig. 2 is combined with fig. 7) in the process of moving up the standard part 1-2, the standard part 1-2 pushes the positioning plate 7 below to move up, and in the process of moving up the positioning plate 7, the connecting plate 7-1 drives the U-shaped rack 7-6 to move up, further drives the gear 7-5 to rotate, further drives the rack 7-3 to move down, further drives the positioning plate 7 above to move down, and the displacement amounts of the two positioning plates 7 are equal;
after the standard part 1-2 is installed (as shown in fig. 1), starting the equipment, driving an adjusting mechanism 4 and a connecting mechanism thereof to rotate by an external power part, putting a to-be-machined part 1-1 above the adjusting mechanism 4 by a feeding mechanism 2, and applying downward pressure to the to-be-machined part 1-1 until the to-be-machined part 1-1 moves downward to an upper positioning plate 7 (the downward pressure applied to the to-be-machined part 1-1 by the adjusting mechanism 4 is smaller than the upward elastic force of an upper elastic telescopic rod five 7-2, so that the to-be-machined part 1-1 stops moving downward, in actual production, an electronic induction means such as a pressure sensor and the like can be installed on the upper positioning plate 7 to control), and then finishing chamfering on the lower end face of the to-be-machined part 1-1; as the inclination of the cutter 4-2 is consistent with the chamfer on the standard part 1-2, and the feed amount of the workpiece to be processed 1-1 is consistent with that of the standard part 1-2 (the displacement amounts of the two positioning plates 7 are equal, and the workpiece to be processed 1-1 and the standard part 1-2 are attached to the positioning plates 7), the chamfer of the workpiece to be processed 1-1 is consistent with that of the standard part 1-2.
