Specific embodiments
[0020] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings.
[0021] As Figures 1-7 shown, a hardware positioning device includes a bottom plate 2, guide rods 3 are symmetrically arranged on the bottom plate 2, a mounting frame 4 is arranged on the upper end surface of the bottom plate 2, the mounting frame 4 is slidably connected to the guide rods 3, a first spring 5 is arranged on the guide rods 3, mounting seats 6 are symmetrically arranged on the bottom plate 2, a rotating shaft 7 is arranged on the two mounting seats 6, a cross-shaped handwheel 8 is arranged on the rotating shaft 7, the rotating shaft 7 penetrates through the mounting frame 4, a first cam 9 is arranged on the outer surface of the rotating shaft 7, the inner side surface of the mounting frame 4 is always in contact with the outer surface of the first cam 9, a sliding cavity 10 is slidably connected to the upper surface of the mounting frame 4, a fixed rod 11 is arranged at the lower end of the sliding cavity 10, a through groove is opened at the upper end of the mounting frame 4, a round rod 12 is arranged inside the through groove, the fixed rod 11 is slidably connected to the round rod 12, a second spring 13 is sleeved on the round rod 12, a vertical shaft 14 is arranged on the inner top surface of the mounting frame 4, a second cam 15 is arranged on the vertical shaft 14, the fixed rod 11 is always in contact with the outer surface of the second cam 15, bevel gears 16 that mesh with each other are arranged on both the rotating shaft 7 and the vertical shaft 14, a groove is opened at the upper end of the sliding cavity 10, and slots for placing hinge pieces 17 are opened on both sides of the groove.
[0022] The four opening positions of the hinge piece 17 are as Figure 2As shown, during use, the operator is located on one side of the handwheel 8 for easy operation of the handwheel 8 and the bench drill 1. From the operator's perspective, according to the positional relationship between the four holes and the operator, the four holes are respectively named the lower right hole, the lower left hole, the upper right hole, and the upper left hole. The opening sequence of the hinge plate 17 is: first the lower right hole, then the lower left hole, then the upper right hole, and finally the upper left hole. After the opening of one hinge plate 17 is completed, except for removing the opened hinge plate 17, the positioning device remains unchanged. The unopened hinge plate 17 is directly placed into the slot and the opening of the unopened hinge plate 17 continues. At this time, the opening sequence is: first the upper left hole, then the upper right hole, then the lower left hole, and finally the lower right hole. The handwheel 8 has an extended handle. After the hinge plate 17 is completely placed into the slot, the lower right hole will be directly below the working end of the bench drill 1, and the opening of the position of the lower right hole on the hinge plate 17 can be directly carried out by the bench drill 1. At this time, there are handles in the handwheel 8 that are parallel and perpendicular to the tabletop to facilitate accurate control of the handwheel 8.
[0023] When it is necessary to drill the lower left hole of the hinge piece 17 after completing the drilling of the lower right hole of the hinge piece 17, first control the handwheel 8 to rotate counterclockwise by 90°. Under the action of the first spring 5, the mounting frame 4 moves away from the first spring 5. During the rotation of the rotating shaft 7, through the external meshing of the bevel gear 16 on the rotating shaft 7 and the bevel gear 16 on the vertical shaft 14, the vertical shaft 14 is driven to rotate. During the rotation of the vertical shaft 14, the second cam 15 is driven to rotate. The second cam 15, through cooperation with the fixed rod 11, pushes the sliding cavity 10 to move to a position away from the handwheel 8. By changing the positions in two directions, the lower left hole of the hinge piece 17 is brought under the working end of the bench drill 1. The position of the lower left hole of the hinge piece 17 can be drilled through the bench drill 1. Then continue to rotate the handwheel 8 counterclockwise and rotate it by 90°, so that the first cam 9 can squeeze the first spring 5 through the mounting frame 4, making the mounting frame 4 move towards the first spring 5. At the same time, the second cam 15 continues to cooperate with the fixed rod 11 to move the sliding cavity 10 further away from the handwheel 8. At this time, the upper right hole of the hinge piece 17 is brought under the working end of the bench drill 1, and at this time, the upper right hole of the hinge piece 17 can be drilled. After completing the drilling, continue to rotate the handwheel 8 counterclockwise and rotate it by 90°. The mounting frame 4 moves away from the first spring 5. Then the second cam 15 continues to cooperate with the fixed rod 11 to move the sliding cavity 10 further away from the handwheel 8, making the upper left hole of the hinge piece 17 come under the working end of the bench drill 1. At this time, the upper right hole of the hinge piece 17 can be drilled. When drilling the four holes of the hinge piece 17, only need to rotate the handwheel 8 counterclockwise and rotate it by 90° in sequence, and then drill through the bench drill 1, then the positioning and drilling operations of the hinge piece 17 can be quickly realized. When the drilling of the last upper left hole is completed, the distance between the sliding cavity 10 and the handwheel 8 is the farthest. At this time, the hinge piece 17 in the slot can be directly removed, and a new un-drilled hinge piece 17 is placed in the slot, and then control the handwheel 8 to rotate 90° clockwise in sequence, so that the drilling processing sequence of the upper left, then upper right, then lower left, and finally lower right of the hinge piece 17 can be realized.
[0024] Further, the outer surface of the first cam 9 is successively provided with a first contact end point 18, a second contact end point 19, a third contact end point 20, and a fourth contact end point 21. When the first contact end point 18 or the third contact end point 20 contacts the mounting frame 4, the distance between the inner side wall of the mounting frame 4 in contact with the first cam 9 and the rotating shaft 7 is the longest. When the second contact end point 19 or the fourth contact end point 21 contacts the mounting frame 4, the distance between the inner side wall of the mounting frame 4 in contact with the first cam 9 and the rotating shaft 7 is the shortest. When drilling the lower right hole or the upper right hole of the hinge blade 17, the first contact end point 18 or the third contact end point 20 of the first cam 9 abuts against the inner side wall of the mounting frame 4. When drilling the lower left hole or the upper left hole of the hinge blade 17, the second contact end point 19 or the fourth contact end point 21 of the first cam 9 abuts against the inner side wall of the mounting frame 4.
[0025] Further, arc-shaped card slots 22 are formed on the outer surfaces of the first contact end point 18, the second contact end point 19, the third contact end point 20, and the fourth contact end point 21. An installation groove is formed inside the inner side wall of the mounting frame 4 in contact with the first cam 9. A compression spring 23 is arranged inside the installation groove, and a positioning ball 24 is arranged at the end of the compression spring 23. The positioning ball 24 can enter the arc-shaped card slot 22. When the arc-shaped card slot 22 reaches the position of the positioning ball 24, under the action of the compression spring 23, the positioning ball 24 is pushed into the arc-shaped card slot 22, so that the sound generated by the impact and the operation can help the staff determine that the handwheel 8 has rotated in place. When the handwheel 8 is rotated again, only a slightly increased rotating force is needed to disengage the positioning ball 24 from the arc-shaped card slot 22, so that the positioning ball 24 can enter the next arc-shaped card slot 22.
[0026] Further, the outer surface of the second cam 15 is successively provided with a first drilling end point 25, a second drilling end point 26, a third drilling end point 27, and a fourth drilling end point 28. The shortest distances between the first drilling end point 25, the second drilling end point 26, the third drilling end point 27, the fourth drilling end point 28 and the vertical shaft 14 are distance a, distance b, distance c, and distance d respectively. The difference between distance b and distance a, the difference between distance c and distance b, and the difference between distance d and distance c are all equal and greater than zero. When the first drilling end point 25 contacts the fixed rod 11, the positioning of the lower right hole of the hinge blade 17 is completed, and at this time, the distance between the sliding cavity 10 and the handwheel 8 is the closest. When the fourth drilling end point 28 contacts the fixed rod 11, the positioning of the upper left hole of the hinge blade 17 is completed, and at this time, the distance between the sliding cavity 10 and the handwheel 8 is the farthest.
[0027] Further, when the first contact end point 18 contacts the inner side wall of the mounting frame 4, the first drilling end point 25 contacts the fixing rod 11; when the second contact end point 19 contacts the inner side wall of the mounting frame 4, the second drilling end point 26 contacts the fixing rod 11; when the third contact end point 20 contacts the inner side wall of the mounting frame 4, the third drilling end point 27 contacts the fixing rod 11; when the fourth contact end point 21 contacts the inner side wall of the mounting frame 4, the fourth drilling end point 28 contacts the fixing rod 11.
[0028] When the device is in use, it is not necessary to pre-mark the hinge piece 17, and the quick positioning of the hinge piece 17 hardware can be quickly achieved, improving the hole-opening efficiency of the hinge piece 17, with simple operation and good use effect.
