[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1 and Figure 3The utility model provides an embodiment of an automatic chip removal structure for rivet nuts, including a machine body 1, which is provided with a motor 8 to provide support, a discharge port is opened on the inner wall of the front end of the machine body 1, and a motor 8 is fixedly connected to the inner wall of the upper end of the machine body 1. The operation of the motor 8 drives the rotation of the turntable 4, so that the rivet nut on the upper end of the turntable 4 rotates, and a connecting pipe 2 is fixedly connected to the inner wall of the upper end of the machine body 1. The connecting pipe 2 is L-shaped, and the rivet nut in the horizontal state is rotated to a vertical state through the fixing block 15 in the connecting pipe 2. The rear end outer wall of the connecting pipe 2 is fixedly connected with a fixing block 15, and the fixing block 15 is trapezoidal. In the horizontal state, the rivet nut is rotated to a vertical state through the inclined surface of the fixing block 15. The left end outer wall of the connecting pipe 2 is fixedly connected with a fixing frame 3. The fixing frame 3 is used to change the position of the rivet nut on the upper end of the turntable 4. The outer wall of the bottom end of 3 is rotatably connected with a turntable 4, which is used to drive the rivet nut to rotate. The inner wall of the bottom end of the turntable 4 is fixedly connected to the output shaft of the motor 8. The outer wall of the upper end of the fixed frame 3 is slidably connected with an adjustment component. A high-speed fan 9 is fixedly connected to the inner wall of the rear end of the body 1. The setting of the high-speed fan 9 removes debris in the rivet nut through strong wind force. A conveyor 11 is provided on the inner wall of the rear end of the body 1. The conveyor 11 drives the fixed seat 10 to move for conveying rivet nuts. A fixed seat 10 is fixedly connected to the outer wall of the upper end of the conveyor 11. The fixed seat 10 is used to carry the vertical rivet nuts falling from the connecting pipe 2, driving the rivet nuts to move, and blowing off the internal debris through the high-speed fan 9. There are multiple fixed seats 10, and the upper end of the fixed seat 10 is arranged in an arc shape. A filter assembly is slidably connected to the inner wall of the right end of the body 1.

[0031] Reference Figure 3 The filter assembly includes a filter plate 12, which blocks the debris and prevents it from scattering from the body 1 to the outside of the body 1. The left end outer wall of the filter plate 12 is slidably connected to the right end inner wall of the body 1, and the front end outer wall of the body 1 is elastically connected to an insert 13 by a spring 14. The rear outer wall of the insert 13 is slidably connected to the front end inner wall of the body 1. By moving the insert 13 forward to release the limit of the filter plate 12, the filter plate 12 can be moved to the right out of the right end inner wall of the body 1, so that the filter plate 12 can be cleaned. At the same time, by moving the filter plate 12 out, the debris in the body 1 can be collected and reused, and the rear outer wall of the insert 13 is slidably connected to the front end inner wall of the filter plate 12, one end of the spring 14 is fixedly connected to the front end outer wall of the body 1, and the other end of the spring 14 is fixedly connected to the rear outer wall of the insert 13.

[0032] Reference Figure 1 and Figure 2The adjusting component includes a sliding door 5, which adjusts the height of the sliding door 5 according to the height of the rivet nut in the horizontal state, so that the rivet nut in the horizontal state can pass through the sliding door 5 into the connecting pipe 2 for the next chip removal process. The outer wall of the sliding door 5 is slidably connected to the inner wall of the upper end of the fixing frame 3, and the outer wall of the right end of the fixing frame 3 is elastically connected to the insert block 2 7 through the spring 2 6. The left outer wall of the insert block 2 7 is slidably connected to the inner wall of the right end of the fixing frame 3. By moving the insert block 2 7 to the right, the insert block 2 7 releases the limit of the sliding door 5, and the sliding door 5 can be moved to adjust the height. The left outer wall of the insert block 2 7 is slidably connected to the inner wall of the right end of the sliding door 5, one end of the spring 2 6 is fixedly connected to the outer wall of the right end of the sliding door 5, and the other end of the spring 2 6 is fixedly connected to the outer wall of the left side of the insert block 2 7.

[0033] Working principle: According to the height of the rivet nut in the horizontal state, by moving the insert block 2 7 to the right, the insert block 2 7 releases the limit on the sliding door 5, and after moving the sliding door 5 to adjust the distance with the turntable 4, the rivet nuts to be removed are poured onto the turntable 4, and the motor 8 is started to drive the turntable 4 to rotate. The rivet nut in the non-horizontal state is blocked by the sliding door 5 and continues to rotate. The rivet nut in the horizontal state enters the connecting pipe 2 through the sliding door 5. The rivet nut in the horizontal state is rotated to the vertical state through the fixed block 15 in the connecting pipe 2. The conveyor 11 drives the fixed seat 10 to rotate, and the rivet nut from the connecting pipe 2 is received. The fallen rivet nuts that fall into the upper end of the fixing seat 10 are blown away by the high-speed fan 9 as the conveyor 11 rotates, and then continue to rotate. When the fixing seat 10 rotates one hundred and eighty degrees, the rivet nuts fall from the discharge port of the body 1, and the blown debris enters the air outlet chamber and is intercepted by the filter plate 12. The limit on the filter plate 12 can be released by moving the insert 13 forward, and the filter plate 12 can be moved to the right out of the right end inner wall of the body 1, so that the filter plate 12 can be cleaned. At the same time, by removing the filter plate 12, the debris in the body 1 can be collected and reused.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
