[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: the fully automatic deburring machine for the inner wall of a perforated aluminum tube comprises a workbench, on which a clamping device and a grinding head mechanism are installed, a material guide trough is arranged on the rear side of the clamping device, a blanking rack is arranged on the side of the material guide trough, the perforated aluminum tube to be processed is placed in the blanking rack, and the bottom perforated aluminum tube enters the material guide trough under the action of gravity; a pushing mechanism is arranged on the rear side of the material guide trough, and the pushing mechanism can push the perforated aluminum tube in the material guide trough into the clamping device, and the clamping device can clamp the perforated aluminum tube; the grinding head mechanism comprises a grinding head motor, and a grinding head is installed on the end of the output shaft of the grinding head motor, and the high-speed rotating grinding head can grind the inner wall of the perforated aluminum tube.

[0006] The clamping device includes a fixed seat, an outer sleeve is arranged inside the fixed seat, and a collet is arranged inside the outer sleeve. The pushing mechanism can push the punching aluminum tube in the guide groove into the collet of the clamping device.

[0014] When the utility model is in use, the perforated aluminum tube to be processed on the blanking rack automatically enters the material guide trough under the action of gravity, and the pushing mechanism can push the perforated aluminum tube in the material guide trough into the clamping device and then retract. The clamping cylinder of the clamping device works to automatically clamp the perforated aluminum tube. After the grinding head enters the perforated aluminum tube, the longitudinal cylinder drives the grinding head mechanism to move longitudinally, so that the grinding head mechanism is horizontally offset to a certain position, so that the grinding head can contact the inner wall of the perforated aluminum tube. Then the transverse cylinder can drive the high-speed rotating grinding head to move transversely along the axial direction of the perforated aluminum tube to grind the inner wall of the perforated aluminum tube. The rotating motor can also work synchronously to drive the perforated aluminum tube to rotate in the opposite direction relative to the grinding head, and the inner wall can be ground in a full circle without moving the grinding head.

The blanking rack 20 is provided with an inclined blanking plate 21, and the bottom of the blanking plate 21 is butted with the upper edge of the material guide trough 40. The blanking rack 20 is filled with perforated aluminum tubes 30 to be processed, and the bottom perforated aluminum tube 30 enters the material guide trough 40 under the action of gravity.

[0018] A pushing mechanism 10 is provided at the rear side of the guide trough 40, and the pushing mechanism 10 can push the perforated aluminum tube 30 in the guide trough 40 into the clamping device 50. The pushing mechanism 10 includes a pushing cylinder 11 and a pushing cylinder 12. When the pushing cylinder 11 drives the pushing cylinder 12 to extend forward, the perforated aluminum tube 30 can be pushed forward.

[0019] The clamping device 50 includes a fixed seat 51, an outer sleeve 52 is arranged in the fixed seat 51, and a collet 53 is arranged in the outer sleeve 52. The pushing mechanism 10 can push the punching aluminum tube 30 in the guide groove 40 into the collet 53 of the clamping device 50. The collet 53 can change the size of the inner diameter of the end of the collet 53 by moving forward and backward relative to the outer sleeve 52, thereby realizing the loosening and clamping of the punching aluminum tube 30. The rear end of the collet 53 is provided with a push-pull disk 58, and an annular groove is arranged on the push-pull disk 58.

The protruding columns 57 of the annular sleeve 56 move forward and backward, which can drive the push-pull disk 58 and the collet 53 to move forward and backward. A clamping cylinder 54 is provided on one side of the fixing seat 51, and a hinged rod 55 is provided on the other end of the fixing seat 51. One side of the annular sleeve 56 is hinged to the hinged rod 55, and the other side is connected to the movable end of the clamping cylinder 54.

The grinding head mechanism 60 is installed on the longitudinal slide 67, and a longitudinal cylinder 68 capable of driving the longitudinal slide 67 is also provided on the transverse slide 64. The longitudinal cylinder 68 drives the grinding head mechanism 60 to move longitudinally, so that the grinding head mechanism 60 is horizontally offset to a certain position, so that the grinding head 62 can contact the inner wall of the punching aluminum tube 30 .

[0022] When the utility model is in use, the perforated aluminum tube 30 to be processed on the blanking rack 20 automatically enters the guide trough 40 under the action of gravity, and the pushing mechanism 10 can push the perforated aluminum tube 30 in the guide trough 40 into the clamping device 50 and then retract. The clamping cylinder 54 of the clamping device 50 works to automatically clamp the perforated aluminum tube 30. After the grinding head 62 enters the perforated aluminum tube 30, the longitudinal cylinder 68 drives the grinding head mechanism 60 to move longitudinally, so that the grinding head mechanism 60 is horizontally offset to a certain position, so that the grinding head 62 can contact the inner wall of the perforated aluminum tube 30. Then the transverse cylinder 65 can drive the high-speed rotating grinding head 62 to move transversely along the axial direction of the perforated aluminum tube 30 to grind the inner wall of the perforated aluminum tube 30. The rotating motor 80 can also work synchronously to drive the perforated aluminum tube 30 to rotate in the opposite direction relative to the grinding head 62, and the inner wall can be ground in a full circle without moving the grinding head 62. After the grinding process is completed, the horizontal cylinder 65 takes the grinding head 62 out of the inner hole of the punched aluminum tube 30.
