[0025] Please see Figures 1 to 6 This utility model provides a technical solution:

[0026] A positioning device for precise drilling of printed circuit boards includes a support platform 1. A lifting block 10 is slidably connected to the inner wall of the support platform 1. A transmission screw 11 is rotatably connected inside the support platform 1. The lifting block 10 is threadedly connected to the transmission screw 11. A connecting rod 6 is symmetrically rotatably connected to the outer side of the lifting block 10. A sliding seat 9 is symmetrically slidably connected inside the support platform 1. The connecting rod 6 is rotatably connected to the sliding seat 9. A mounting base 3 is fixedly connected to the top of the sliding seat 9. A locking block 18 is equidistantly slidably connected inside the mounting base 3. A clamping plate 4 is provided on one side of the mounting base 3. A fixing block 21 is equidistantly fixedly connected to one side of the clamping plate 4. The fixing block 21 has a slot 20 inside that cooperates with the locking block 18. A connecting rod 6 is symmetrically slidably connected to the outer side of the clamping plate 4. A positioning plate 5 is attached, and anti-slip pads are provided on one side of the positioning plate 5 and one side of the clamping plate 4. In use, the rotation of the transmission screw 11 drives the lifting block 10 to slide, the movement of the lifting block 10 drives the connecting rod 6 to rotate, and the rotation of the connecting rod 6 drives the sliding seat 9 to slide. The sliding seat 9 drives the clamping plate 4 to move through the mounting base 3, thereby positioning the two sides of the circuit board through the two sets of clamping plates 4. The other two sides of the circuit board can be positioned through the two sets of positioning plates 5, making the positioning effect of the circuit board more accurate and facilitating subsequent drilling operations. The position of the fixing block 21 can be limited and fixed by the movement of the locking block 18 into the slot 20, which facilitates the installation of the clamping plate 4.

[0027] Furthermore, a transmission frame 2 is fixedly connected to the bottom of the support platform 1. A worm gear 13 is rotatably connected inside the transmission frame 2. A worm wheel 14 that works with the worm gear 13 is fixedly connected to the outside of the transmission screw 11. A motor 7 is fixedly connected to the outside of the transmission frame 2. The output end of the motor 7 is fixedly connected to the worm gear 13. The motor 7 drives the worm wheel 14 to rotate through the worm gear 13. The worm wheel 14 drives the transmission screw 11 to rotate.

[0028] Furthermore, a limit rod 8 is fixedly connected to the inner wall of the support platform 1, and the lifting block 10 is slidably connected to the limit rod 8. The movement of the lifting block 10 can be limited by the limit rod 8 to prevent deviation.

[0029] Furthermore, the support platform 1 has symmetrically provided limit grooves 12 inside, and the sliding seat 9 is slidably connected to the limit grooves 12. The movement of the sliding seat 9 can be limited by the setting of the limit grooves 12.

[0030] Furthermore, the inner wall of the mounting base 3 is fixedly connected with slide rods 16 at equal intervals, and the locking block 18 is slidably connected to the slide rods 16. A spring 17 is sleeved on the outer side of the slide rods 16 and on one side of the locking block 18. The spring 17 drives the locking block 18 to move and reset. The slide rods 16 can limit the movement of the locking block 18 to prevent deviation.

[0031] Furthermore, the mounting base 3 has a sliding connection of a push rod 19 inside, and a locking block 18 is fixedly connected to the push rod 19. One end of the push rod 19 is fixedly connected to a push block 15.

[0032] Furthermore, the clamping plate 4 has an adjusting block 23 symmetrically slidably connected inside, the positioning plate 5 is fixedly connected to the adjusting block 23, and the clamping plate 4 has a bidirectional lead screw 22 rotatably connected inside, the adjusting block 23 is threadedly connected to the bidirectional lead screw 22, and a knob is fixedly connected to one end of the bidirectional lead screw 22. The knob drives the bidirectional lead screw 22 to rotate, and the rotation of the bidirectional lead screw 22 drives the adjusting block 23 to move, and the adjusting block 23 drives the positioning plate 5 to move.

[0033] When positioning the printed circuit board during use, motor 7 is started. Motor 7 drives worm gear 14 to rotate via worm 13. Worm gear 14 drives transmission screw 11 to rotate. The rotation of transmission screw 11 causes lifting block 10 to slide along limit rod 8. The movement of lifting block 10 causes connecting rod 6 to rotate. The rotation of connecting rod 6 causes sliding seat 9 to slide along limit groove 12. Sliding seat 9 drives clamping plate 4 to move via mounting base 3. Thus, the two sets of clamping plates 4 position both sides of the circuit board. The bidirectional lead screw 22 rotates, causing the adjusting block 23 to move. The adjusting block 23 then moves the positioning plate 5. The two sets of positioning plates 5 can position the other two sides of the circuit board, making the positioning of the circuit board more accurate and facilitating subsequent drilling operations. When the clamping plate 4 needs to be replaced, push the push block 15. The push block 15 moves the locking block 18 through the push rod 19, causing the locking block 18 to move out of the locking slot 20, so that the clamping plate 4 can be removed for replacement. The operation is convenient and easy to use.
