Each damping buffer 38 is fixedly installed with a caster at its bottom end.

[0037] By setting the vibration output of the excitation motor 37, the abrasive material can be fully dispersed;

[0038] The inner wall of the housing 1 is rotatably connected to the outer grinding cylinder 2, which is a hollow cylindrical structure with an open front end. The inner wall of the outer grinding cylinder 2 is rotatably connected to the inner rotating shell 3.

[0040] By setting the position and specifications of the two driven bevel gears, the inner rotating shaft and the outer grinding cylinder 2 can rotate in a coaxial and opposite direction at a differential speed when the servo motor 4 is working. By setting the coaxial and opposite direction at a differential speed of rotation of the inner rotating shaft and the outer grinding cylinder 2, the abrasive material can fully contact the surface of the automotive parts, thereby achieving effective deburring and polishing of the surface of the automotive parts.

An outer rubber cylinder 22 is fixedly installed on the periphery of the inner clamping cylinder 21. A set of vent holes connected to the outer rubber cylinder 22 are opened inside the inner clamping cylinder 21. The outer rubber cylinder 22 is made of wear-resistant rubber.

[0049] The inner wall of the inner rotating shell 3 is equipped with a set of regularly distributed sand modules 9, and the inner wall of the outer grinding cylinder 2 is fixedly equipped with a transmission gear ring 10. The set of sand modules 9 are all driven by the transmission gear ring 10, and a sand discharge mechanism is installed on the inner side of the outer grinding cylinder 2.

[0050] The sand-dispersing module 9 includes a forward rotating shaft 24 rotatably connected to the inner rotating shell 3 and a steering shaft 25 rotatably connected to the inner rotating shell 3. The inner wall of the forward rotating shaft 24 is rotatably connected to a reverse rotating shaft 26. A set of dispersing glue rods 27 arranged in a circular array are fixedly installed on the circumferential side of both the forward rotating shaft 24 and the reverse rotating shaft 26.

[0053] A deburring method for a deburring device used in the processing of automotive parts includes the following steps:

[0054] SS001, Preset: Before the part grinding operation, open the material gate 35 and place the car part to be ground between the two clamping mechanisms. After placement, the user drives the transmission screw 8 to enable the two clamping mechanisms to fully clamp the car part. After the part is clamped, the valve cylinder 32 seals the sand discharge hole 31 by setting the unloading push rod 34. After sealing, the interior of the outer grinding cylinder 2 is filled with grinding abrasive. The filling amount of grinding abrasive is one-third of the volume of the outer grinding cylinder 2.

[0055] After steps SS001 and SS002, the two excitation motors 37 output vibration frequencies in a set state. The servo motor 4 drives the inner rotating shell 3 and the outer grinding cylinder 2 to move in opposite directions on the same axis. During the circumferential motion of the inner rotating shell 3, the transmission gear ring 10 effectively drives the forward rotating shaft 24 and the reverse rotating shaft 26. The rotation directions of the forward rotating shaft 24 and the reverse rotating shaft 26 are opposite. By setting the coaxial reverse rotation of the forward rotating shaft 24 and the reverse rotating shaft 26, the abrasive material is fully dispersed. The dispersed abrasive material acts on the automotive parts, thereby achieving deburring of the surface of the automotive parts. After the servo motor 4 has worked for a specified time, the grinding and deburring of the surface of the automotive parts is completed.

[0056] SS003, Sand Discharge: After the grinding abrasive has been used for a specified time, the valve cylinder 32 loses its blocking effect on the sand discharge hole 31 by setting the discharge push rod 34, opening the valve plate at the discharge pipe 30, and then fully discharging the worn-out grinding abrasive. After the abrasive is discharged, the valve cylinder 32 re-seals the sand discharge hole 31 by setting the discharge push rod 34.

After sealing, the interior of the outer grinding cylinder (2) is filled with grinding abrasive. The filling amount of grinding abrasive is one-third of the volume of the outer grinding cylinder (2). SS002, Deburring, After step SS001, two excitation motors (37) output vibration frequency in the set state. Servo motor (4) drives the inner rotating shell (3) and the outer grinding cylinder (2) to move in opposite directions at different speeds on the same axis. During the circumferential motion of the inner rotating shell (3), the transmission gear ring (10) effectively drives the positive rotating shaft (24) and the negative rotating shaft (26). The positive rotating shaft (24) and the negative rotating shaft (26) rotate in opposite directions. By setting the positive rotating shaft (24) and the negative rotating shaft (26) to rotate in opposite directions on the same axis, the grinding abrasive is fully dispersed. The dispersed grinding abrasive acts on the automotive parts, thereby achieving deburring of the surface of the automotive parts. After the servo motor (4) has worked for a specified time, the grinding and deburring of the surface of the automotive parts is completed. SS003, Sand discharge: After the grinding abrasive has been used for a specified time, the valve cylinder (32) loses its blocking effect on the sand discharge hole (31) by setting the discharge push rod (34), opening the valve plate at the discharge pipe (30), and then fully discharging the worn-out grinding abrasive. After the abrasive is discharged, the valve cylinder (32) re-blocks the sand discharge hole (31) by setting the discharge push rod (34).
