Detailed implementation manners
[0019] As Figures 1-4 shown, a positioning and drilling device for a metallurgical lower plate includes a bottom plate 1. A strip hole 2 is opened in the middle of the bottom plate 1. Limit holes 3 are opened on both sides of the strip hole 2. The limit holes 3 are symmetrically distributed and inclined. It also includes a drilling mechanism 4 and a positioning mechanism 5. The positioning mechanism 5 is arranged on the bottom plate 1 and is used for clamping and positioning the formed workpiece. The drilling mechanism 4 is arranged at the middle position on one side of the upper part of the bottom plate 1. The drilling mechanism 4 is located above the bottom plate 1. The bottom plate 1 supports the drilling mechanism 4 and the positioning mechanism 5. The workpiece is quickly clamped and positioned through the positioning mechanism 5, and the drilling of the workpiece is realized through the omnidirectional movement and adjustment of the drilling mechanism 4 above the workpiece.
[0020] As Figures 1-3As shown in the figure, in order to achieve rapid positioning and clamping of the workpiece, the positioning mechanism 5 includes a first slider 6, a second slider 7, a first limiting wheel 8, a second limiting wheel 9 and a propulsion component 10. The first slider 6 is slidably arranged in the strip-shaped hole 2, the second slider 7 is slidably arranged in the limiting hole 3, the first limiting wheel 8 is rotatably connected to the upper part of the first slider 6, the second limiting wheel 9 is rotatably connected to the upper part of the second slider 7. A first rotating shaft 11 is rotatably connected to the bottom of the first slider 6, and a second rotating shaft 12 is rotatably connected to the bottom of the second slider 7. A connecting rod 13 is fixedly connected between the first rotating shaft 11 and the second rotating shaft 12 which are symmetrically arranged. The connecting rod 13 is symmetrically arranged in a vertically staggered manner. The propulsion component 10 is fixedly connected to one side of the upper part of the bottom plate 1. The first slider 6 slides horizontally along the bottom plate 1 in the strip-shaped hole 2, and the symmetric second sliders 7 slide relatively in the limiting holes 3. The symmetric second sliders 7 are connected to the first slider 6 through the connecting rod 13, and under the limiting action of the strip-shaped hole 2 and the limiting holes 3, the linkage of the first limiting wheel 8 and the second limiting wheel 9 is realized. When one side of the workpiece pushes the first limiting wheel 8 to move, the first limiting wheel 8 drives the first slider 6 to move, and the second limiting wheel 9 and the second slider 7 move synchronously and oppositely in the limiting hole 3 to adjust, so as to realize the clamping and positioning of the workpiece;
[0021] In order to enable the workpiece to move and contact the first limiting wheel 8, the propulsion component 10 includes a support plate 14, a first air cylinder 15 and a push plate 16.

The sliding rod 17 penetrates through the support plate 14 and is slidably arranged in the support plate 14. The sliding rods 17 are symmetrically distributed with the first air cylinder 15 as the center. The telescopic end of the first air cylinder 15 pushes the push plate 16 to extend out. The push plate 16 contacts the side wall of the workpiece and pushes the workpiece to move on the bottom plate 1, so that the workpiece passes between the symmetric second limiting wheels 9 and contacts the first limiting wheel 8. When pushing and moving, the sliding rods 17 on both sides increase the moving stability of the push plate 16.
[0022] As shown in the figure, in order to enable the drilling mechanism 4 to move omnidirectionally above the workpiece for drilling, the drilling mechanism 4 includes a column 18, a limit frame 19, a stud 20, a moving block 21, a second rotary motor 22 and a lifting adjustment assembly 23. The column 18 is rotatably arranged on one side of the upper part of the bottom plate 1. The limit frame 19 is fixedly connected to the upper part of the outer side wall of the column 18. The stud 20 is rotatably connected between the inner end face of the limit frame 19 and the outer side wall of the column 18. A first rotary motor 24 is installed on the outer wall of one end of the limit frame 19 away from the column 18. The output end of the first rotary motor 24 is threadedly connected to the stud 20. The moving block 21 is threadedly connected to the outer side wall of the stud 20. The moving block 21 is slidably arranged in the limit frame 19. The lifting adjustment assembly 23 is fixedly connected to the bottom wall of the moving block 21. The second rotary motor 22 is movably connected to the lower part of the moving block 21 through the lifting adjustment assembly 23. The column 18 supports the limit frame 19. By driving the rotation of the second rotary motor 22 through the column 18, the direction adjustment of the second rotary motor 22 is realized. By driving the rotation of the stud 20 by the first rotary motor 24, the moving block 21 slides in the support frame, and the position adjustment of the second rotary motor 22 is realized. By using the lifting adjustment assembly 23, the second rotary motor 22 is lowered to realize drilling of the workpiece;
[0023] In order to realize the downward drilling of the second rotary motor 22, the lifting adjustment assembly 23 includes a connecting plate 25, a support plate 26 and a second cylinder 27. The connecting plate 25 is fixedly connected to the bottom wall of the moving block 21. The connecting plates 25 are symmetrically arranged. The support plate 26 is fixedly connected to the bottom of the symmetric bottom plate 1. The second cylinder 27 is arranged at the center of the upper part of the support plate 26. The second cylinder 27 is located between the symmetric connecting plates 25. The telescopic end of the second cylinder 27 penetrates through the support plate 26 and is slidably arranged below the support plate 26. The telescopic end of the second cylinder 27 is fixedly connected to the second rotary motor 22. A fixing plate 28 is fixedly connected to the outer side wall of the second rotary motor 22. The fixing plates 28 are symmetrically arranged. A limiting rod 29 is fixedly connected to the upper wall of the fixing plate 28. The other end of the limiting rod 29 penetrates through the support plate 26 and is slidably arranged in the support plate 26. The output end of the second rotary motor 22 is detachably provided with a drill bit 30. By driving the second cylinder 27 to extend, the telescopic end of the second cylinder 27 pushes the second rotary motor 22 downward. At the same time, the limiting rod 29 outside the connecting plate 25 slides in the support plate 26 and pushes the fixing plate 28 downward to improve the moving stability of the second rotary motor 22. By driving the second rotary motor 22 to drive the drill bit 30 to rotate and the second cylinder 27 to continuously extend, after the drill bit 30 contacts the workpiece, the drilling operation is realized.
[0024] Wherein, support legs 31 are fixedly connected to the bottom corners of the bottom plate 1 for supporting the device, increasing the height of the bottom plate 1 and facilitating the movement of the symmetric connecting rods 13.
[0025] During specific use, in the initial state, the symmetrical limiting wheels II 9 are in a state of moving away from each other. The operator places the workpiece on the bottom plate 1, extends the telescopic end of the driving cylinder I 15, and pushes one side of the workpiece towards one side of the limiting wheel I 8 through the push plate 16. When the other side of the workpiece contacts the limiting wheel I 8, the limiting wheel I 8 drives the slider I 6 to horizontally slide in the strip-shaped hole 2. Under the connection action of the symmetrical connecting rod 13, the slider II 7 and the limiting wheel II 9 slide in the limiting hole 3 and move closer to each other to clamp the adjacent two side walls of the limiting wheel I 8, realizing the positioning and clamping of the workpiece.
[0026] During drilling, start the rotating motor II 22 to drive the drill bit 30 to rotate. According to the drilling position, rotate the limiting frame 19, and drive the rotating motor I 24 to drive the screw rod 20 to rotate to adjust the position of the moving block 21, so that the rotating motor II 22 is located above the drilling position. Then drive the cylinder II 27 to extend, and the cylinder II 27 pushes the rotating motor II 22 downward to make the drill bit 30 contact the upper part of the workpiece to realize drilling.
