[0024] like Figure 1-3 As shown, an automatic unloading and chamfering device for steel pipe fittings comprises a working platform 1, on which two chamfering units arranged relatively and capable of relative movement are installed, between which two chamfering units are arranged two jigs 3 arranged relatively and used for placing pipe fittings 2, and above which an arc-shaped pressing plate 4 is arranged, and the arc-shaped pressing plate 4 is connected with a clamping unit, which drives the arc-shaped pressing plate 4 to descend by the clamping unit, so that the arc-shaped pressing plate 4 clamps the pipe fitting 2 in the jig 3, and then moves the two chamfering units toward each other, so as to perform chamfering processing on both ends of the pipe fitting 2; between the two jigs 3, a first cylinder 5 is arranged, and a top plate 6 is installed at the output end of the first cylinder 5, and an arc-shaped limiting column 7 is fixed on one side of the top of the top plate 6, and the arc-shaped limiting column 7 is fixed on one side of the top of the top plate 6. The arc surface of the column 7 is aligned with the pipe fitting 2 placed in the fixture 3, and the top of the top plate 6 is tilted from top to bottom by the arc limiting column 7 in the direction away from the arc limiting column 7. The first cylinder 5 drives the top plate 6 to rise, and the arc surface of the arc limiting column 7 lifts the pipe fitting 2 in the fixture 3, so that the pipe fitting 2 rolls down along the top of the top plate 6 in the direction of tilting from top to bottom, thereby completing automatic unloading; a blocking column 19 is fixed on the side of the top of the top plate 6 away from the arc limiting column 7 to block the rolling pipe fitting 2 to prevent the pipe fitting 2 from rolling too fast and being difficult to collect; a guide frame 8 docked with the top plate 6 is installed on the working platform 1, and a collection box is provided below the guide frame 8, and the pipe fitting 2 continues to roll along the guide frame 8 and falls into the collection box;

[0025] The chamfering unit includes a base 9 slidably connected to the working platform 1, a rotating motor 10 and a reducer 11 are installed on the base 9, the output end of the rotating motor 10 is connected to the input end of the reducer 11, a chamfering tool 12 is installed on the output end of the reducer 11, the rotating motor 10 drives the reducer 11 to rotate, and the reducer 11 drives the chamfering tool 12 to rotate, so that the chamfering tool 12 performs chamfering on the pipe 2; a slide rail 13 is installed on the working platform 1, a slide groove 14 slidably connected to the slide rail 13 is provided at the bottom of the base 9, a second cylinder 15 is installed on the working platform 1, a push block 16 connected to the output end of the second cylinder 15 is fixed on the side of the base 9, the second cylinder 15 drives the push block 16 to move, and the push block 16 drives the base 9 to move, so that the base 9 moves along the length direction of the slide rail 13 through the slide groove 14;

[0026] The clamping unit includes a support frame 17 installed on the working platform 1 and a third cylinder 18 installed on the support frame 17. The arc pressure plate 4 is installed on the output end of the third cylinder 18. The third cylinder 18 drives the arc pressure plate 4 to descend or rise, thereby clamping or loosening the pipe fitting 2; a rubber pad is attached to the concave part of the arc pressure plate 4 to increase friction and prevent the pipe fitting 2 from rotating during chamfering.

[0027] like Figure 1-3 As shown, when the blanking chamfering device is in use, the manipulator places the pipe fitting 2 in the two fixtures 3, and then the third cylinder 18 drives the arc-shaped pressing plate 4 to descend, thereby pressing the pipe fitting 2 in the fixture 3.

After the chamfering is completed, the second cylinder 15 drives the push block 16 to move, and the push block 16 drives the base 9 to move, so that the two The relatively arranged chamfering units move towards each other and return to their original positions, and at the same time, the third cylinder 18 drives the arc pressure plate 4 to rise and release the pipe fitting 2. After the pipe fitting 2 is released, the first cylinder 5 drives the top plate 6 to rise, and the arc surface of the arc limiting column 7 lifts the pipe fitting 2 in the fixture 3, so that the pipe fitting 2 rolls down along the top of the top plate 6 from top to bottom. When the pipe fitting 2 rolls to the side of the top plate 6 away from the arc limiting column 7, the blocking column 19 will block the pipe fitting 2, and the pipe fitting 2 will stop rolling and stay on the top plate 6. Then the first cylinder 5 drives the top plate 6 to descend, and the pipe fitting 2 will stay on the guide frame 8 while following the top plate 6 to descend. As the blocking column 19 continues to descend until the side of the blocking column 19 is completely out of contact with the pipe fitting 2, the pipe fitting 2 continues to roll along the guide frame 8 and falls into the collection box.
