Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 as well as Figure 2 This utility model provides a circuit board nut riveting and positioning fixture, including a base frame 4, a support column 5 on the base frame 4, a bearing frame 3 on the support column 5, and a fixing component 1 inside the bearing frame 3;

[0025] The fixing component 1 includes a first positioning frame 12 and a second positioning frame 18. The first positioning frame 12 and the second positioning frame 18 are symmetrically arranged in the bearing frame 3. A first screw nut 13 is provided on one side surface of the first positioning frame 12, and a second screw nut 17 is provided on one side surface of the second positioning frame 18. The first screw nut 13 and the second screw nut 17 are symmetrically arranged on both sides of the bidirectional ball screw 16. The bidirectional ball screw 16 is rotatably arranged on one side surface of the bearing frame 3. Specifically, the first positioning frame 12 and the second positioning frame 18 are symmetrical L-shaped structures, which can support circuit boards of different specifications and position the circuit boards in the X-axis direction.

[0026] One end of the bidirectional ball screw 16 is also connected to the drive shaft of the drive motor 15. The drive motor 15 is located on one side surface of the support frame 3. By running the drive motor 15, the drive motor 15 can control the rotation direction of the bidirectional ball screw 16.

[0027] According to the specifications of the circuit board, the distance between the first positioning frame 12 and the second positioning frame 18 is adjusted. By driving the motor 15, the rotation of the bidirectional ball screw 16 is controlled. By moving the first screw nut 13 and the second screw nut 17 in multiple directions, the distance between the first positioning frame 12 and the second positioning frame 18 is adjusted. The circuit board is clamped and positioned by the first positioning frame 12 and the second positioning frame 18.

[0028] In one embodiment, a first guide block 11 is provided on the other side of the first positioning frame 12, and a second guide block 19 is provided on the other side of the second positioning frame 18. Both the first guide block 11 and the second guide block 19 are slidably disposed in the guide groove 14, which is disposed on the other side surface of the bearing frame 3. The movement of the first positioning frame 12 and the second positioning frame 18 drives the first guide block 11 and the second guide block 19 to move in the guide groove 14, which can guide the movement of the first positioning frame 12 and the second positioning frame 18 and improve the stability of the first positioning frame 12 and the second positioning frame 18 when they move.

[0029] Please see Figure 3 as well as Figure 4 Both the first positioning frame 12 and the second positioning frame 18 are provided with two sets of adjustable bidirectional limiting structures 2. The bidirectional limiting structure 2 includes an adjustment port 206, which is respectively located on one side of the first positioning frame 12 and the second positioning frame 18. Limiting components for positioning the circuit board in the Y and Z directions are symmetrically arranged in the adjustment port 206.

[0030] In one embodiment, the limiting component includes a Y-axis positioning plate 201, which is disposed on one side of the first positioning frame 12 and the second positioning frame 18. An adjusting block 202 is disposed on one side surface of the Y-axis positioning plate 201, and the adjusting block 202 is movably disposed in the adjusting port 206. An adjusting screw 203 is disposed on one side surface of the adjusting block 202, and a locking nut 204 is also disposed on the adjusting screw 203. By fitting the Y-axis positioning plate 201 against the side of the circuit board, it can position and lock the circuit board in the Y-axis direction according to different specifications.

[0031] In one embodiment, a mounting plate 209 is provided on one side surface of the Y-axis positioning plate 201. A threaded hole 208 is provided on the mounting plate 209, and a Z-axis locking screw 207 is rotatably provided in the threaded hole 208.

Specifically, a buffer pad 210 is also provided at the bottom of the Z-axis locking screw 207. The buffer pad 210 can be made of silicone to prevent the Z-axis locking screw 207 from damaging the circuit board.

[0032] Furthermore, a limiting slider 211 is also provided on one side of the adjusting block 202. The limiting slider 211 is slidably disposed in the limiting groove 205. The limiting groove 205 is disposed on one side surface of the adjusting port 206. The movement of the adjusting block 202 drives the limiting slider 211 to move within the limiting groove 205, thereby limiting and guiding the movement of the adjusting block 202.

[0033] The specific working principle of this utility model is as follows:

[0034] First, according to the specifications of the circuit board, the drive motor 15 is controlled to run. The drive motor 15 drives the bidirectional ball screw 16 to rotate. As the bidirectional ball screw 16 rotates, it drives the first screw nut 13 and the second screw nut 17 to move in opposite directions. The first screw nut 13 drives the first positioning frame 12 to move, and the second screw nut 17 drives the second positioning frame 18 to move. The distance between the first positioning frame 12 and the second positioning frame 18 is adjusted so that the bottom of the circuit board is in contact with the first positioning frame 12 and the second positioning frame 18. After the first positioning frame 12 and the second positioning frame 18 are in contact with the side of the circuit board, the first positioning frame 12 and the second positioning frame 18 position the circuit board in the X-axis direction.

[0035] Then push the Y-axis positioning plate 201 to move. The Y-axis positioning plate 201 drives the adjusting block 202 to move within the adjusting port 206. When the Y-axis positioning plate 201 is in contact with the side of the circuit board, tighten the locking bolt. The locking nut 204 fixes the adjusting block 202 within the adjusting port 206. Then rotate the Z-axis locking screw 207. The Z-axis locking screw 207 makes the buffer pad 210 fit with the circuit board and fixes the Z-axis direction of the circuit board. Place the device on the worktable of the riveting machine and rivet the nut onto the circuit board using the riveting machine.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
