[0028] The upper surface of the base body 1 is provided with a circular rotating groove 5. The rotating seat 6 is rotatably connected to the rotating groove 5, and the upper surface of the rotating seat 6 is horizontal with the upper surface of the base body 1. The upper surface of the rotating seat 6 is provided with a number of concentric circular slots 16. Magnetic strips 17 are installed inside the slots 16. When the part is placed on the rotating seat 6, the magnetic strips 17 generate an adsorption force on the part, preventing the part from shifting when the rotating seat 6 rotates. When the part is placed on the rotating seat 6, the part to be cut or trimmed is placed at the arc edge 10 or the guide slope 12.
[0029] A top groove 13 is provided on the upper surface of the base body 1 on the side away from the arc edge 10. The bottom of the pressure rod 4 is inserted into the top groove 13 and the bottom of the pressure rod 4 is slidably connected to the top groove 13. Several springs 18 are fixedly installed on the inner bottom surface of the top groove 13. The other end of the spring 18 is fixedly connected to the bottom of the pressure rod 4. The pressure plate 7 is fixedly installed on the inner top surface of the pressure rod 4. Several anti-slip rubber strips are pasted on the lower surface of the pressure plate 7. When trimming the parts, the pressure rod 4 is pressed down so that the pressure plate 7 fixes the parts on the rotating seat 6. The anti-slip rubber strips prevent the parts from moving during the trimming process.
[0030] The left and right sides of the base body 1 are respectively provided with side slot holes 19. The side slot holes 19 are divided into upper slot holes 1901 and lower slot holes 1902. The upper and lower ends of the insertion rod 8 are respectively inserted into the upper slot hole 1901 and the lower slot hole 1902, and the position of the upper slot hole 1901 corresponds to several limiting slots 15.
[0031] A clip 20 is fixedly installed at the lower end of the insertion rod 8. The edge of the clip 20 is slidably connected to the inner surface of the lower slot 1902. A baffle 21 is fixedly installed on the outermost side of the lower slot 1902. The baffle 21 is slidably connected to the lower part of the insertion rod 8.
[0032] When the insert rod 8 is inserted into the innermost side of the side slot 19, the upper part of the insert rod 8 is inserted into one of the limiting slots 15. At this time, the distance between the clip 20 and the baffle 21 is greater than the length of the upper end of the insert rod 8 inserted into the limiting slot 15.
[0033] When the insert rod 8 is pulled outward, the retainer 20 is blocked by the baffle 21 to prevent the insert rod 8 from coming out as a whole. At the same time, the top of the insert rod 8 comes out of the limiting groove 15. At this time, the rotating seat 6 can be rotated to adjust the angle of the part. After the adjustment is completed, the insert rod 8 is pushed inward so that the top of the insert rod 8 is inserted into the corresponding limiting groove 15 to limit the rotating seat 6.
[0034] The base body 1 has fasteners 22 welded to both sides for connecting bolts.
[0035] Working principle: This type of mechanical parts processing and trimming base, when in use, when the part is placed on the rotating seat 6, the magnetic strip 17 generates an attractive force on the part, preventing the part from shifting when the rotating seat 6 rotates. When the part is placed on the rotating seat 6, the part to be cut or trimmed is positioned at the curved edge 10 or the guide slope 12. When trimming the part, pressing down the pressure rod 4 causes the pressure plate 7 to fix the part on the rotating seat 6. The anti-slip rubber strip prevents the part from moving during the trimming process. When the insert rod 8 is pulled outward, the clamp 20 is blocked by the baffle 21 to prevent the insert rod 8 from coming out completely. At the same time, the top of the insert rod 8 comes out of the limiting groove 15. At this time, the rotating seat 6 can be rotated to adjust the angle of the part. After adjustment, push the insert rod 8 inward so that the top of the insert rod 8 is inserted into the corresponding limiting groove 15 to limit the rotating seat 6.
