Detailed Description

The cutter integrated device comprises a driving shell 2 and a connecting plate 3; the driving shell 2 and the connecting plate 3 are both in a round cake shape. Six connecting columns 4 are adopted to fix the driving shell 2 and the connecting plate 3. Six connecting columns 4 are uniformly distributed in a ring shape. A planetary gear structure is arranged in the driving shell 2. The gear ring driving mechanism comprises a gear ring 6, wherein the diameter of the gear ring 6 is smaller than that of a driving shell 2, and the gear ring 6 and the driving shell 2 are arranged to be a concentric ring structure. The planet carrier 7 is a triangular plate, and the planet carrier 7 is fixed at the top of the driving shell 2 by using screws. The planet carrier 7 and the top of the driving shell 2 are provided with round holes which are used for arranging a rotating shaft. The center of planet carrier 7 is equipped with pivot 10, and pivot 10 stretches into the round hole of planet carrier 7 and drive shell 2, passes through shaft coupling fixed connection with the output shaft of motor 1. The rotating shaft 10 is sleeved with a sun wheel 9; the sun gear 9 is connected with the rotating shaft 10 through a spline. The motor 1 is started, and the rotating shaft 10 rotates, so that the sun wheel 9 is driven to rotate. Three fixed shafts 11 are arranged at three corners of the planet carrier 7. The center of the planet wheel 8 is provided with a through hole. A part of the inner wall of the through hole is smooth, and a part of the through hole is provided with internal threads. The fixed shaft extends into the smooth part of the inner wall, and a bearing is arranged between the fixed shaft and the smooth part of the inner wall. The tail of the tool shank 51 is also provided with external threads, and the tail of the tool shank extends into the internal thread part of the through hole. One side of the planet wheel 8 meshes with the sun wheel 9 and the other side meshes with the ring gear 6. The sun wheel 9 drives the planet wheel 8 to rotate, the planet wheel 8 rotates around the fixed shaft 11, and the planet wheel 8 drives the gear ring 6 to rotate. The knife handle 51 penetrates through the connecting plate 3 and extends into the driving shell 1, and bearings are arranged between the knife handle and the connecting plate 3 and between the knife handle and the driving shell 2 to reduce abrasion. The cutter head extends below the connecting plate 3. A ball bearing is arranged between the planet wheel 8 and the bottom of the driving shell 2; ball bearings are mounted between the ring gear 6 and the drive housing 2. The ball bearing can reduce abrasion and also can play a supporting role.

The specific implementation process is as follows: the entire tool holder is mounted on the lifting arm, for example, the drive housing is locked to the lifting arm by screws. Starting the motor, rotating the motor, and rotating the rotating shaft under the action of the coupler; because the rotating shaft is in splined connection with the driving wheel, the driving wheel is driven to rotate, and then the driven wheel rotates around the fixed shaft to drive the gear to rotate circularly. The driven wheel also drives the knife handle to rotate, so that the knife head also rotates. Under the action of the mechanical arm, the rotating cutter head punches the workpiece. Compared with the prior art, the processing efficiency is three times that of the prior art in the same time. And, the error of the hole pitch is reduced. The production efficiency and the quality are improved.
