[0016] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0017] See also Figures 1 to 6The utility model provides a chamfering tool for an aluminum tube, which includes a base plate 1. Mounting holes 5 are symmetrically provided on the left and right sides of the upper end of the base plate 1. The mounting holes can mount the base plate on the workbench of a chamfering machine. A chamfering tool is installed on the tool head of a drilling machine to form a chamfering machine. The base plate can be mounted below the chamfering machine. A turntable 2 driven by a servo motor 8 is rotatably provided on the upper end of the base plate 1. Support rods 3 for accommodating the insertion of aluminum tubes are evenly distributed on the upper end of the turntable 2 along its axis circumferentially. A clamping assembly 4 is provided on the rear side of the upper end of the base plate 1, which can clamp the aluminum tube sleeved on the rear support rod 3. Every time the servo motor drives the turntable to rotate once, the aluminum tube is inserted into the frontmost support rod. The aluminum tube on the rear support rod is located under the chamfering tool of the chamfering machine. The clamping assembly clamps the aluminum tube on the rear support rod. After the aluminum tube is stabilized, the chamfering machine chamfers the inner edge of its upper end. After chamfering is completed, the clamping assembly releases the aluminum tube on the rear support rod, and then the turntable rotates the chamfered aluminum tube to the front side, removes it and replaces it with a new aluminum tube. There is no need to hold the aluminum tube under the tool and there is no need to press the aluminum tube by hand during chamfering.

[0018] The clamping assembly 4 includes a servo electric cylinder 4.1 disposed above the base plate 1 and facing forward, and clamping members 4.3 are symmetrically and rotatably disposed on the left and right sides above the base plate 1, and a column 4.4 is vertically disposed on the upper side of the rear end of the clamping member 4.3, and an elastic member 4.5 is connected between the two columns 4.4. The piston rod end of the servo electric cylinder 4.1 is connected to a spreading bar 4.2 for driving the two clamping members 4.3 to clamp the aluminum tube. The servo electric cylinder drives the spreading bar to move backward, and the spreading bar drives the two clamping members to rotate, and the front ends of the two clamping members clamp the aluminum tube on the rear support rod. After chamfering, the servo electric cylinder drives the spreading bar to move forward, and the two clamping members are reset under the action of the elastic member, thereby loosening the aluminum tube.

[0019] A first gear 6 is coaxially connected to the lower part of the turntable 2, and a second gear 7 rotating on the bottom plate 1 is meshed with the front end of the first gear 6, and the second gear 7 is keyed to the output shaft of the servo motor 8. The second gear is driven to rotate by the servo motor, and the second gear rotates with the turntable through the first gear. The two gears can be designed to extend the servo motor forward so that the servo motor avoids the working table of the chamfering machine.

[0020] The bottom of the base plate 1 is provided with a groove 1.1 for accommodating the first gear 6 and the second gear 7. The groove arrangement can keep the first gear and the second gear away from the working table of the chamfering machine, and is convenient for processing.

[0021] In order to stabilize and support the servo motor, a concave stabilizing block 9 is fixedly arranged on the groove 1.1, and the servo motor 8 is arranged on the stabilizing block 9.

[0022] The chamfering tool of the aluminum tube of the utility model can automatically rotate the aluminum tube to the chamfering position and clamp the aluminum tube, and there is no need to hold the aluminum tube and approach the tool; the servo motor drives the turntable to rotate the aluminum tube to the chamfering position, and the clamping assembly clamps the aluminum tube on the rear support rod to stabilize the aluminum tube, and after the chamfering is completed, the clamping assembly loosens the aluminum tube on the rear support rod, and then the turntable rotates the chamfered aluminum tube to the front side, removes it and replaces it with a new aluminum tube; the expansion bar driven by the servo electric cylinder moves backward to drive the two clamping parts to rotate to clamp the aluminum tube on the rear support rod, and after the chamfering is completed, the servo electric cylinder drives the expansion bar to move forward, and the two clamping parts are reset under the action of the elastic part, thereby loosening the aluminum tube; the two gears can be designed to extend the servo motor forward, so that the servo motor avoids the workbench of the chamfering machine; the groove setting can make the first gear and the second gear avoid the workbench of the chamfering machine, and the processing is convenient.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
