[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A screw drilling device includes a workbench 1, a lifting plate 13 is movably mounted on the right side of the top of the workbench 1, a transverse slide groove is provided on the lifting plate 13, a slide rail arranged along the length direction of the slide groove is installed in the slide groove, a movable plate 14 is slidably connected to the slide rail, a first motor 15 is movably mounted on the top of the movable plate 14, a drill bit 16 is movably mounted on the output end of the first motor 15, and a screw drive component 2 is provided on the top of the workbench 1;

[0031] The screw drive component 2 includes a first frame plate 21 fixedly mounted on the left and right sides of the rear end of the top of the workbench 1, and a first frame rod 22 is fixedly mounted on the top of the two groups of the first frame plates 21. A movable groove 24 is provided on the upper end of the workbench 1 in front of the two groups of the first frame plates 21. A second frame plate 25 is movably mounted inside the movable groove 24. A second frame rod 26 is fixedly mounted on the top of the two groups of the second frame plates 25. The surfaces of the second frame rod 26 and the first frame rod 22 are movably sleeved with a first bearing 23. The screw drive component 2 also includes a column 29 fixedly mounted on the rear end of the workbench 1, and a pressure plate 210 is movably mounted on the top of the two columns 29. A driving wheel 212 is movably mounted on the front end of the pressure plate 210.

[0032] A screw 27 is movably installed inside the movable groove 24 at the front left side of the top of the workbench 1. The rear end of the screw 27 is movably connected to the second frame plate 25 on the left side of the top of the workbench 1. A second rotating handle 28 is movably installed at the front end of the workbench 1. The front end of the screw 27 is fixedly connected to the second rotating handle 28. A track wheel 213 is movably installed at the front left side of the pressing plate 210. The track wheel 213 is fixedly connected to the driving wheel 212 through a connecting rod. A second motor 211 is fixedly installed on the top of the pressing plate 210. The surface of the track wheel 213 The surface of the workbench 1 is engaged with the output end surface of the second motor 211 and is sleeved with a transmission track 214. The driving wheel 212 is located above the first rack 22 and the second rack 26. The front end of the workbench 1 is fixedly mounted with a gun rack 11, and the interior of the gun rack 11 is clamped with an air gun 12. The air outlet of the air gun 12 is facing the right side of the first rack 22 and the second rack 26. The first turning handle 18 is movably mounted on the right side of the bottom of the workbench 1, and the first turning handle 18 can control the lifting and lowering of the lifting plate 13. The front end of the movable plate 14 is fixedly mounted with a moving handle 17.

[0033] By adopting the above technical solution, when in use, the distance between the second frame rod 26 and the first frame rod 22 is first adjusted according to the diameter of the screw rod, and the second rotating handle 28 is rotated. The second rotating handle 28 drives the second frame plate 25 to move in the moving groove 24 through the screw rod 27. The two sets of second frame plates 25 installed on the surface of the workbench 1 are both located in the moving groove 24. At the same time, the tops of the two sets of second frame plates 25 are jointly installed with the second frame rod 26. Therefore, even if the position of the second frame plate 25 on one side is adjusted, the two sets of second frame plates 25 and the second frame rod 26 can be displaced at the same time. The second frame rod 26 moves forward to expand The distance between the second frame rod 26 and the first frame rod 22 is suitable for a screw with a larger diameter. Moving the second frame rod 26 backward narrows the distance between the second frame rod 26 and the first frame rod 22, which is suitable for a screw with a smaller diameter. After adjusting the distance between the second frame rod 26 and the first frame rod 22, the screw is placed between the two. At this time, the first bearing 23 installed on the surface of the second frame rod 26 and the first frame rod 22 is in direct contact with the screw. The pressure plate 210 is lowered to press the driving wheel 212 on top of the screw. Finally, the position of the lifting plate 13 is adjusted by the first turning handle 18 so that the drill bit 16 installed on the output end of the first motor 15 is facing the screw. At the center of the screw end face, the second motor 211 is turned on first when drilling, and the second motor 211 drives the track wheel 213 to rotate through the transmission track 214, and the track wheel 213 drives the driving wheel 212 to rotate. When the driving wheel 212 rotates, it cooperates with the first bearing 23 to drive the screw to rotate. At this time, the first motor 15 is started again, and the output end of the first motor 15 drives the drill bit 16 to rotate. The staff holds the moving handle 17 and pushes the moving handle 17 to the left, so that the drill bit 16 moves to the left to drill the screw end face. Through the above structural design, the device is convenient for pre-drilling operations on the screw, and is adjustable at the same time. The second rack 26 of the section improves the scope of use of the present device. Pre-drilling operations can be performed on screw rods with larger or smaller diameters. When drilling a hole in the screw rod, it is only necessary to place the screw rod between the second rack 26 and the first rack 22, and then cover the drive wheel 212 above the screw rod to restrict the screw rod. Finally, the high-speed rotating drill bit 16 can be moved by moving the handle 17 to complete the pre-drilling operation of the screw rod. The overall use is quick and convenient, and the pre-drilling operation of the screw rod can be completed quickly. During the drilling operation, the air gun 12 on the gun frame 11 can be turned on to blow air to the drilling position of the screw rod to blow away the iron filings.

[0034] Specifically, such as Figures 1 to 4As shown, a screw rod interference component 3 is provided on the left side of the workbench 1, and the screw rod interference component 3 includes a support plate 31 movably mounted on the left side of the workbench 1, a support plate 34 is fixedly mounted on the top of the support plate 31, a clamping sleeve 35 is movably sleeved on the surface of the support plate 34, and a fourth turning handle 36 is movably mounted on the top of the clamping sleeve 35, a support column 37 is placed inside the support plate 34, a clamping head 38 is fixedly mounted on the right side of the support column 37, a second bearing 381 is inlaid on the right side surface of the clamping head 38, the outer ring of the second bearing 381 is fixedly connected to the clamping head 38, and the inner ring of the second bearing 381 is fixedly mounted with a contact plate 382, and the front and rear ends of the upper inner wall of the clamping head 38 are fixed A spring piece 383 is fixedly installed, and a steel ball 384 is movably installed on the surface of the spring piece 383. The clamping head 38 faces the direction of the first frame rod 22 and the second frame rod 26. The bottom of the fourth rotating handle 36 passes through the clamping sleeve 35 and contacts the anti-pillar 37. A mounting groove 39 is provided on the left side of the workbench 1, and a clamping slot 32 is provided at the bottom of the support plate 31. A third rotating handle 33 is movably installed on the left side of the support plate 31. The right side of the third rotating handle 33 can extend into the clamping slot 32. The anti-pillar 37 can adjust the length of the right side extending out of the support plate 34 through the clamping sleeve 35 and the fourth rotating handle 36. The support plate 31 can be adjusted to its position on the workbench 1 through the clamping slot 32, the third rotating handle 33 and the mounting slot 39.

[0035] By adopting the above technical solution, a mounting groove 39 is provided on the left side of the workbench 1, and a support plate 31 is installed inside the mounting groove 39. A card slot 32 is provided at the bottom of the support plate 31. The support plate 31 is clamped in the mounting groove 39 through the card slot 32 and is fixed by the third handle 33. The right end of the third handle 33 can extend into the card slot 32. Therefore, when the third handle 33 is rotated, the right end of the third handle 33 can be moved out of or into the card slot 32, thereby fixing the support plate 31 and the workbench 1 through the card slot 32 and the mounting groove 39, and also facilitating the adjustment of the support plate 31. 1 is adjusted, a support column 37 is placed in the support plate 34, a clamping sleeve 35 is sleeved on the top of the support plate 34, and the clamping sleeve 35 covers the top of the support column 37. At the same time, a fourth rotating handle 36 is installed on the top of the clamping sleeve 35. The bottom of the fourth rotating handle 36 passes through the clamping sleeve 35 and can contact the top of the support column 37. Therefore, when the fourth rotating handle 36 is selected, the support column 37 can be fixed. The clamping head 38 on the right side of the support column 37 is located between the second frame rod 26 and the first frame rod 22. The screw rod is placed between the second frame rod 26 and the first frame rod 22. At this time, the position of the clamping head 38 is adjusted by the support plate 31 so that the screw rod The left end of the screw rod is against the contact plate 382, and the contact plate 382 is installed in the clamping head 38 through the second bearing 381. Due to the existence of the second bearing 381, the left end of the screw rod is in direct contact with the contact plate 382 without affecting the rotation of the screw rod. At the same time, two sets of spring plates 383 are provided above the contact plate 382. The spring plates 383 can limit the screw rod, and the left end of the screw rod is pressed down. After the left end of the screw rod is pressed down, the right end will be in a tilted state. At this time, the driving wheel 212 is used to press the screw rod down, so that the screw rod can be better restricted between the driving wheel 212, the second rack rod 26, and the first rack rod 22, thereby lifting the screw rod. The friction with the driving wheel 212 ensures that the driving wheel 212 can drive the screw to rotate. The screw is drilled by the drill bit 16 in the rotating state and the screw is drilled by the drill bit 16 in the stationary state. In comparison, the drilling efficiency can be significantly improved when the screw is in the rotating state. At the same time, the left end of the screw is supported by the contact plate 382. When the drill bit 16 exerts force to drill a hole at the right end of the screw, it can also prevent the screw from being displaced. The surface of the spring piece 383 is installed with a steel ball 384 to assist the screw in rotating, and the spring piece 383 will not limit the rotation of the screw. Through the above structural design, the drilling efficiency of the screw by this device is greatly improved.

[0036] Working principle: When in use, first adjust the position of the second frame rod 26 and the clamping head 38 according to the diameter of the screw rod. After adjustment, place the screw rod between the second frame rod 26 and the first frame rod 22, and then lower the pressure plate 210 to press the driving wheel 212 above the screw rod. Turn on the second motor 211, and the output end of the second motor 211 drives the transmission track 214 to rotate. The transmission track 214 drives the track wheel 213 to rotate, and the track wheel 213 drives the driving wheel 212 to rotate, thereby driving the screw rod below to rotate through the first bearing 23 through the driving wheel 212. By moving the handle 17, the movable plate 14 is moved close to the screw rod, and the height of the lifting plate 13 is adjusted so that the drill bit 16 is aligned with the center of the circle of the end face of the screw rod. Then turn on the first motor 15, and the output end of the first motor 15 drives the drill bit 16 to rotate at high speed. The staff pushes the movable plate 14 toward the screw rod by moving the handle 17 to perform the drilling operation. When drilling, the air gun 12 on the gun frame 11 can be turned on to blow air at the hole of the screw rod to blow away the iron filings generated during drilling. After the drilling is completed, the pressure plate 210 can be lifted to remove the screw rod.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
