[0023] 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.
[0024] See also Figure 1-7The present invention provides an embodiment of a PCB board half-hole processing structure, including a machine tool 1,
[0025] Slide rails 2 are fixedly installed on the front and rear sides of the upper end of the machine tool 1, and slides 3 are slidably installed on the two sets of slide rails 2. A fixed plate 4 is fixedly installed on the right side of the upper end of the slide 3, and an electric telescopic rod 5 is provided on the fixed plate 4. The lower end of the electric telescopic rod 5 is provided with a drilling component 6. Four groups of first slide grooves 9 are opened in the left end of the machine tool 1, and clamping components are provided in the four groups of first slide grooves 9. A limit component is provided on the clamping component. This device clamps the PCB board placed on the machine tool 1 through the clamping component, and the clamping component clamps the corners of the PCB board and limits and fixes it through the limit component, which can ensure that the PCB board remains fixed during the processing process.
[0026] Furthermore, the clamping assembly includes a motor 7 and a first bevel gear 8. The motor 7 is fixedly installed in the left end of the machine tool 1. The first bevel gear 8 is fixedly installed on the output shaft of the motor 7. The four groups of first slides 9 are all rotatably installed with screws 10. The opposite ends of the four groups of screws 10 are all fixedly installed with second bevel gears 11. The four groups of second bevel gears 11 are meshed with the first bevel gear 8. The four groups of first slides 9 are all slidably installed with clamps 12. The four groups of clamps 12 are threadedly sleeved on the four groups of screws 10. The upper ends of the four groups of clamps 12 are each provided with grooves 13 on the opposite side. This structure drives the first bevel gear 8, the four groups of screws 10 and the four groups of second bevel gears 11 to rotate through the output shaft of the motor 7, and the rotation of the four groups of screws 10 drives the four groups of clamps 12 to slide closer, thereby clamping and fixing the PCB board placed between the four groups of clamps 12, which is convenient for clamping and fixing PCB boards of different specifications.
[0027] Furthermore, the four groups of clamps 12 are arranged in a four-corner array, and the inner wall angles of the four groups of grooves 13 on the four groups of clamps 12 are all right angles. This structure is based on the shape of the inner walls of the four groups of grooves 13, so that when the clamps 12 are fitted with the corners of the PCB board, the corners of the PCB board and the inner walls of the grooves 13 can fit tightly and adapt to each other.
[0028] Furthermore, the limiting assembly includes a movable groove 14, which is opened in the upper end of the splint 12, and a movable block 15 is slidably installed in the movable groove 14. A first spring 16 is installed in the movable groove 14, and a protrusion 17 is fixedly installed on the upper side of the movable block 15. A push plate 18 is installed in the upper end of the splint 12, and a rotating plate 19 is rotatably installed in the upper end of the splint 12. The rotating plate 19 is rotatably connected to the push plate 18, and one end of the rotating plate 19 in the groove 13 is hingedly installed with a second slider 20, and a pressure plate 21 is slidably installed in the groove 13. A second slide groove 22 is opened on the upper side of the pressure plate 21, and the second slider 20 slides. It is installed in the second slide groove 22, and two groups of third slide grooves 24 are opened on the inner wall of the groove 13. Second springs 25 are installed in the two groups of third slide grooves 24. Third sliders 26 are slidably installed in the two groups of third slide grooves 24. The two groups of third sliders 26 are fixedly connected to the two groups of pressure plates 21. When the clamping plate 12 is in contact with the edge of the PCB board, this structure squeezes the movable block 15 through the edge of the PCB board and drives the protrusion 17 to squeeze the push plate 18 upward. The push plate 18 is squeezed by the force to drive the rotating plate 19 to swing, and the rotating plate 19 drives the pressure plate 21 to move downward and fit the PCB board, thereby limiting the upper and lower positions of the PCB board when clamping.
[0029] Furthermore, a protective pad 23 is glued to the lower side of the pressing plate 21. The protective pad 23 is made of rubber. This structure, based on the material of the protective pad 23, avoids friction damage when the pressing plate 21 is fitted with the PCB board.
[0030] Furthermore, the second slide groove 22 and the two groups of third slide grooves 24 and the second slider 20 and the two groups of third sliders 26 are all T-shaped, and the second slider 20 and the two groups of third sliders 26 are adapted to the inner walls of the second slide groove 22 and the two groups of third slide grooves 24. This structure, based on the shape of the second slide groove 22 and the two groups of third slide grooves 24 and the second slider 20 and the two groups of third sliders 26, ensures that the second slider 20 and the two groups of third sliders 26 will not be forced to detach when sliding on the inner walls of the second slide groove 22 and the two groups of third slide grooves 24, so that the second slider 20 and the two groups of third sliders 26 slide straightly on the inner walls of the second slide groove 22 and the two groups of third slide grooves 24.
[0031] Furthermore, the lower inner walls of the grooves 13 on the four groups of clamps 12 are flush with the upper inner walls of the machine tool 1. This structure, based on the position of the lower inner walls of the grooves 13 on the four groups of clamps 12, enables the PCB board to fit tightly against the upper side of the machine tool 1 when the PCB board is fixed in the grooves 13 on the four groups of clamps 12.
[0032] Furthermore, the pressure plate 21 is consistent in size with the inner wall of the groove 13, and the pressure plate 21 and the lower inner wall of the groove 13 are arranged parallel to each other. This structure makes the lower side of the pressure plate 21 and the lower inner wall of the groove 13 parallel to the upper and lower sides of the corners of the PCB board when the pressure plate 21 slides up and down in the groove 13, thereby achieving tight fixation of the corners of the PCB board.
[0033] Working principle: When half hole processing is performed on PCB board, Figure 2 、 Figure 3 and Figure 5 As shown, the PCB board is placed on the left end of the machine tool 1, and the PCB board is between the four groups of clamping plates 12. The motor 7 is started, and the output shaft of the motor 7 drives the first bevel gear 8 to rotate. The rotation of the first bevel gear 8 drives the four groups of screws 10 and the four groups of second bevel gears 11 to rotate. The rotation of the four groups of screws 10 drives the four groups of clamping plates 12 to slide close in the four groups of first slide grooves 9, so that the four groups of clamping plates 12 slide close to clamp the four corners of the PCB board, and when the four corners of the PCB board are inserted into the four groups of grooves 13, as shown in FIG. Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, the four corners of the PCB board squeeze the four groups of movable blocks 15, and the four groups of movable blocks 15 are squeezed to slide into the four groups of movable grooves 14, and the four groups of movable blocks 15 drive the four groups of protrusions 17 to slide. While the four groups of protrusions 17 slide, they squeeze the four groups of push plates 18 upward. According to the movement of the lever, the four groups of push plates 18 are squeezed to raise the ends of the four groups of rotating plates 19 connected to the four groups of push plates 18, and the opposite ends of the four groups of rotating plates 19 are lowered, and the four groups of rotating plates 19 drive the four groups of second sliders 20 to move upward. The four groups of second slide grooves 22 slide, so that when the four groups of pressure plates 21 slide downward in the four groups of grooves 13, the four groups of rotating plates 19 and the four groups of pressure plates 21 are adjusted and slid. Then the four groups of pressure plates 21 slide downward through the two groups of third sliders 26 on the left and right sides and slide and guide in the two groups of third slide grooves 24, thereby preventing the four groups of pressure plates 21 from tilting when sliding in the four groups of grooves 13. The four groups of pressure plates 21 slide down to press down and clamp the corners of the PCB board. The above is the entire working principle of the present utility model.
