The motor 62 is turned on, and the rotation of the motor 62 drives the rotating shaft 63 and the polishing wheel 64 to rotate. The sliding rod 5 is moved, and the movement of the sliding rod 5 drives the polishing components 6 to move. When the polishing components 6 are moved under the sheet metal parts, the polishing wheel 64 polishes the burrs. There is no need to polish the hardware parts separately, which provides convenience for the staff.

[0016] The workbench 1 is equipped with a transmission assembly 8 inside, and a retainer assembly 9 is provided on the top surface of the workbench 1; The transmission component 8 assists the polishing component 6 in moving. During polishing, the transmission component 8 can be used to repeatedly polish the hardware parts, resulting in a good deburring effect. The retainer component 9 helps to fix the hardware parts that need to be punched or polished, which helps to improve the accuracy of punching and the deburring effect.

[0017] Specifically, such as Figure 1-3 As shown, the punching assembly 3 includes a cylinder 31, a piston rod 32, and a punch 33. The cylinder 31 is fixedly connected to the top surface of the gantry frame 2, the piston rod 32 is slidably connected to the bottom surface of the cylinder 31, and the punch 33 is fixedly connected to the bottom end of the piston rod 32.

[0018] The fixture assembly 9 includes a first fixing plate 91, a threaded rod 92, and a clamping plate 93. Two first fixing plates 91 are fixedly connected to both sides of the top surface of the worktable 1. Two threaded rods 92 are threadedly connected to the two first fixing plates 91.

The worm gear 84 is meshed with a worm wheel 85.

[0020] The worm gear 85 is fixedly sleeved with a rotating rod 86. Two bevel gears 88 are fixedly connected to both ends of the rotating rod 86. The two bevel gears 88 mesh with two bevel gears 89. The two bevel gears 89 are fixedly connected to two lead screws 810. The two lead screws 810 are threadedly connected to two sliding rods 5. The threads of the two lead screws 810 are in opposite directions. The two lead screws 810 are rotatably connected to the side wall of the square cavity 4. Two square cavities 87 and one square cavity 811 are opened on the side of the worktable 1 near the motor frame 81. The bevel gears 88 and 89 are both located inside the square cavity 87.

[0022] After placing the sheet metal part under the gantry frame 2, adjust its position so that the punching position is below the punch 33. Rotate the threaded rod 92, which moves the clamping plate 93, clamping and fixing the sheet metal part. Open the cylinder 31, which moves the piston rod 32, which in turn moves the punch 33. Simultaneously, the fixing plate 94 on the piston rod 32 also moves. When the punch 33 contacts the sheet metal part, the fixing plate 96 also contacts the sheet metal part. The fixing plate 96 is equipped with an anti-slip pad. The punch 33 punches the sheet metal part. During punching, the cooperation between the fixing plate 96 and the fixing plate 94 compresses the damping spring 95, making the fixing plate 96 hold the sheet metal part more firmly and preventing damage during punching. The displacement of the sheet metal ensures the accuracy of punching. The punching waste falls through the through hole 7 and into the worktable 1 below the blanking hole 10. After punching, the bottom surface of the sheet metal is deburred. The second motor 82 is turned on. The rotation of the second motor 82 drives the second rotating shaft 83 and the worm gear 84 to rotate. The rotation of the worm gear 84 drives the meshing worm wheel 85 to rotate. The rotation of the worm wheel 85 drives the rotating rod 86 to rotate. The rotation of the rotating rod 86 causes the first bevel gear 88 to drive the meshing bevel gear 89 to rotate. The rotation of the second bevel gear 89 drives the lead screw 810 to rotate. The rotation of the lead screw 810 drives the sliding rod 5 to move. The movement of the sliding rod 5 moves the polishing component 6 to the polishing position. The transmission component 8 can make the polishing component 6 reciprocate to polish the sheet metal, improving the deburring effect.
