[0026] See also Figure 1-7 , a specific implementation of a rivet nut nailing machine includes a frame 1, a driving cylinder 2, a feeding tray 4 and a feeding guide rail 5. The feeding tray 4 is arranged at the top of the frame 1, and a nailing notch 12 is opened on one side of the frame 1. The upper edge of the nailing notch 12 is the nut feeding end 5113, and the lower edge of the nailing notch 12 is the plate feeding end 5114. The driving cylinder 2 is vertically fixedly connected to the top of the nut feeding end 5113, and a nut fixture 7 is provided at the bottom of the nut feeding end 5113. The nut fixture 7 and the feeding tray 4 are connected through the feeding guide rail 5. A feeding tray bracket 11 is provided on the top of the frame 1, and the feeding tray 4 is fixedly connected to the top of the feeding tray bracket 11. The feeding tray 4 is arranged above the frame 1 through the feeding tray bracket 11. An air source triplex 6 is also provided on one side of the frame 1. The air source triplex 6 includes an air filter, a pressure reducing valve and an oil mist collector. The oil mist collector, the pressure reducing valve and the air filter are connected to the cylinder body of the driving cylinder 2 in sequence.

[0027] Specific examples Figure 2-4 As shown, an outward-turned forming seat 8 is provided at the center of the sheet material feeding end 5114 and is located directly below the driving cylinder 2. The outward-turned forming seat 8 includes a sleeve shaft 81 and a forming shaft core 82. The sleeve shaft 81 is a hollow structure. The forming shaft core 82 is inserted at the center of the sleeve shaft 81, and the top of the forming shaft core 82 is a positioning protrusion 821. The positioning protrusion 821 extends to the top of the sleeve shaft 81. A downward-concave outward-turned groove 811 is provided at the center edge of the sleeve shaft 81. The cross-sectional structure of the outward-turned groove 811 is an arc-shaped structure.

[0028] An outward-turning forming seat 8 is provided at the center of the plate feeding end 5114 and is located directly below the driving cylinder 2. When the upper sleeve nut passes downward through the wooden board, the edge of the bottom can be sleeved on the positioning protrusion 821 at the top of the forming shaft core 82. At the same time, under the impact force of the driving cylinder 2, it can be deformed along the outward-turning groove 811 at the edge of the forming shaft core 82, so that the sleeve nut has an outward-protruding ring structure after being turned outward, which can ensure the integrity of the appearance of the sleeve nut after being turned outward. At the same time, the sleeve nut can maintain a certain hardness and strength, and the connection with the wooden board is more stable.

[0029] In a further embodiment, Figure 2 and 5 As shown, a punching rod 3 is provided at the output end 21 at the bottom of the driving cylinder 2. The punching rod 3 can pass through the nut jig 7 downward through the driving cylinder 2 and extend to the top of the plate feeding end 5114. The top of the punching rod 3 is connected to the output end 21 of the driving cylinder 2. The bottom end of the punching rod 3 is provided with a magnetic ring 33. The magnetic ring 33 is embedded in the bottom end surface of the punching rod 3. The top end of the punching rod 3 is a mounting threaded portion 31. The punching rod 3 is threadedly connected to the output end 21 of the driving cylinder 2 through the mounting threaded portion 31. The structure between the punching rod 3 and the driving cylinder 2 is detachable.

[0030] A magnetic ring 33 is provided at the bottom end of the punching rod 3. The magnetic ring 33 is an annular structure and is evenly distributed on the bottom end surface of the punching rod 3, so that the end of the punching rod 3 that contacts the sleeve nut has strong magnetism. When the punching rod 3 is located in the nut jig 7 and collides with the sleeve nut, the top end of the sleeve nut can be adsorbed on the end of the magnetic ring 33 close to the punching rod 3. At the same time, the punching rod 3 carries the sleeve nut out of the nut jig 7. When it is in the air, the sleeve nut can be firmly adsorbed on the bottom of the punching rod 3 and nailed into the wooden board at a uniform position, which effectively reduces the deviation of the sleeve nut and improves the accuracy of the nailing position of the sleeve nut.

[0031] Specifically, such as Figure 6-7 As shown, one end of the nut jig 7 is provided with a blanking hole 71 that is connected up and down, and a horizontal feeding channel 72 is provided at the end of the nut jig 7 close to the feeding guide rail 5. The feeding channel 72 is connected to the middle part of the blanking hole 71 at the end away from the feeding guide rail 5. The end of the punching rod 3 close to the magnetic ring 33 can be moved downward through the blanking hole 71 by driving the cylinder 2. A plurality of bevel blocks 73 are provided at the bottom of the blanking hole 71, and a horizontal stroke groove 74 matching the bevel block 73 is provided on the side wall of the blanking hole 71. The bevel block 73 can be embedded in the inside of the blanking hole 71. A reset spring 75 is provided between the end of the bevel block 73 close to the blanking hole 71 and the horizontal stroke groove 74. The end of the bevel block 73 away from the blanking hole 71 can extend to the inside of the blanking hole 71 through the reset spring 75.

[0032] One end of the feed guide rail 5 is the feed end 51, and the other end of the feed guide rail 5 is the discharge end 52. The middle part of the feed guide rail 5 is a hollow guide channel 53. The feed guide rail 5 is connected to the feed tray 4 through the feed end 51, and the feed guide rail 5 is connected to the feed channel 72 of the nut fixture 7 through the discharge end 52.

[0033] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the above-disclosed technical contents without departing from the scope of the technical solution of the present invention.
