A driving assembly for driving the rotating rod to rotate is arranged at the top of the drilling machine body 1, and a lifting assembly for driving the drill rod 11 to lift and lower in the vertical direction is also arranged on the drilling machine body 1, so that the drill rod 11 can drill a columnar workpiece 10 below.

[0034] Reference Figure 2 and Figure 3, a base 2 is provided at the bottom end of the drilling machine body 1, and the base 2 is arranged horizontally, and the top surface of the base 2 is used to place a columnar workpiece 10. A clamping assembly for fixing the bottom end of the columnar workpiece 10 is provided on the top surface of the base 2. The clamping assembly includes four locking bolts 3 threadedly connected to the top surface of the base 2, and the four locking bolts 3 are arranged in a circular array; the axial direction of the locking bolts 3 is arranged horizontally, and the axes of the four locking bolts 3 intersect at one point. Therefore, after placing the bottom end of the columnar workpiece 10 on the top surface of the base 2, the locking bolts 3 are rotated so that the end of the locking bolts 3 is pressed against the surface of the columnar workpiece 10, and the columnar workpiece 10 can be fixed on the base 2; then the top end of the columnar workpiece 10 is drilled through the drill rod 11. Furthermore, a pressure block is provided at the end of the locking bolt 3, and a rubber pad is bonded to the side of the pressure block away from the locking bolt 3, thereby increasing the contact area between the end of the locking bolt 3 and the columnar workpiece 10, thereby enhancing the fixing effect on the columnar workpiece 10.

[0035] Reference Figure 3 and Figure 4 The base 2 is slidably arranged on the drilling machine body 1 in the horizontal direction, and an adjustment mechanism for adjusting the position of the base 2 is arranged on the drilling machine body 1. The adjustment mechanism includes a first adjustment component 4 and a second adjustment component 5. The first adjustment component 4 includes a mounting plate 41 and a first screw 42. The mounting plate 41 is arranged on the drilling machine body 1, and the mounting plate 41 is a strip plate, and the plate surface of the mounting plate 41 is arranged horizontally; a slider is fixedly connected to the bottom of the base 2, and a slide groove 411 is provided on the top surface of the mounting plate 41 along its own length direction, and the slider is slidably engaged in the slide groove 411, so that the base 2 is slidably arranged on the top surface of the mounting plate 41. The first screw 42 is arranged along the length direction of the mounting plate 41, and the first screw 42 is rotatably arranged on the mounting plate 41 around its own axis; a threaded hole is provided on the slider, and the slider and the first screw 42 are threadedly connected. Therefore, by rotating the first screw 42, the base 2 can slide along the length direction of the mounting plate 41, thereby adjusting the position of the base 2 and the columnar workpiece 10 installed on the base 2.

[0036] The second adjustment assembly 5 includes a mounting rod 51 and a second screw rod 52. The mounting rod 51 is arranged on the drilling machine body 1, and the mounting rod 51 is arranged horizontally, and the length direction of the mounting rod 51 is perpendicular to the length direction of the mounting plate 41. A clamping block is fixedly connected to the bottom surface of the mounting plate 41, and a clamping groove 511 is provided on the top surface of the mounting rod 51 along its own length direction. The clamping block is slidably clamped in the clamping groove 511, so that the mounting plate 41 is slidably arranged on the top surface of the mounting rod 51. The second screw rod 52 is arranged along the length direction of the mounting rod 51, and the second screw rod 52 is rotatably arranged on the mounting rod 51 around its own axis, and the second screw rod 52 is threadedly connected to the clamping block. Therefore, by rotating the second screw rod 52, the mounting plate 41 can slide along the length direction of the mounting rod 51, and the position of the mounting plate 41 and the base 2 can be adjusted, thereby further adjusting the position of the columnar workpiece 10.

[0037] Further, refer to Figure 1 , the mounting rod 51 is sleeved on the outer side of the drilling machine body 1, so that the mounting rod 51 is slidably arranged on the drilling machine body 1 in the vertical direction. The mounting rod 51 is provided with a locking assembly 6, which includes an insertion rod 61 and a spring 62. A connecting hole is provided on the mounting rod 51, the axis of the connecting hole is arranged horizontally, and the insertion rod 61 is slidably arranged in the connecting hole. The spring 62 is connected between the end of the insertion rod 61 and the mounting rod 51, and the spring 62 is in a stretched state. A plurality of insertion holes 12 are evenly spaced in the vertical direction on the drilling machine body 1, and the axis of the insertion hole 12 is parallel to the axis of the connecting hole. Therefore, as the mounting rod 51 slides, when the connecting hole and the insertion hole 12 are in a coaxial state, the spring 62 causes the end of the insertion rod 61 to be inserted into the insertion hole 12, which can limit the sliding of the mounting rod 51 relative to the drilling machine body 1, thereby fixing the mounting rod 51 on the drilling machine body 1. Since the position of the mounting rod 51 is adjustable, the position of the base 2 can be adjusted according to the length of the columnar workpiece 10, thereby ensuring the drilling effect.

[0038] Reference Figure 1 and Figure 5 The drilling machine body 1 is also provided with a mounting block 7; the mounting block 7 is provided with a through hole 71 adapted to the drilling machine body 1, and the mounting block 7 is sleeved on the outside of the drilling machine body 1; the mounting block 7 is fixedly connected with a protrusion 711 on the inner wall of the through hole 71, and an annular groove is provided on the outer wall of the drilling machine body 1, and the protrusion 711 is engaged in the annular groove, so that the mounting block 7 is rotatably arranged on the drilling machine body 1 around the vertical axis. A workbench 72 is fixedly connected to the outer wall of one side of the mounting block 7, and the workbench 72 is arranged horizontally. The workbench 72 and the mounting block 7 are at the same height and are both located between the drill rod 11 and the base 2.

[0039] Reference Figure 1, a limit assembly 8 is provided on the workbench 72, and the limit assembly 8 includes a clamping plate 81, a guide rod 82 and a double-headed screw 83. Two clamping plates 81 are provided, and the two clamping plates 81 are arranged in parallel with each other. The guide rod 82 is fixedly connected to the upper side of the top surface of the workbench 72, and the guide rod 82 is slidably arranged between the two clamping plates 81, so that the clamping plate 81 and the guide rod 82 are slidably connected. The double-headed screw 83 is parallel to the guide rod 82, and the double-headed screw 83 is rotated around its own axis and arranged on the top surface of the workbench 72; the thread directions of the two ends of the double-headed screw 83 are opposite, and the two clamping plates 81 are respectively provided with screw holes that are compatible with the two ends of the double-headed screw 83; the two ends of the double-headed screw 83 are respectively threadedly connected with the two clamping plates 81. Therefore, by rotating the double-headed screw 83, the two clamping plates 81 can be brought close to each other, so that the workpiece placed on the top surface of the workbench 72 can be clamped and fixed, and then the workpiece can be drilled.

[0040] Therefore, when it is necessary to drill a smaller workpiece, the mounting block 7 can be rotated so that the workbench 72 is located directly below the drill rod 11, and then the workpiece is placed on the workbench 72, and the double-headed screw 83 is rotated so that the two clamping plates 81 are close to each other, and the workpiece is clamped and fixed by the clamping plates 81; then the workpiece can be drilled through the drill rod 11. When it is necessary to drill a longer columnar workpiece 10, the mounting block 7 can be rotated so that the workbench 72 is rotated to the side away from the drill rod 11, and then the bottom end of the columnar workpiece 10 is placed on the base 2, and the columnar workpiece 10 is fixed by the locking bolt 3, and then the drilling can be carried out; the device can drill both smaller and larger columnar workpieces 10, so it has stronger applicability.

[0041] Reference Figure 1 and Figure 5 , the mounting block 7 is also provided with a threaded hole, in which a fastening bolt 9 is threadedly connected, and the axis of the fastening bolt 9 is horizontal; the drilling machine body 1 is provided with a limiting groove for the end of the fastening bolt 9 to be screwed in, and two limiting grooves are provided, and are symmetrically arranged on both sides of the drilling machine body 1. When the end of the fastening bolt 9 is screwed into one of the limiting grooves, the workbench 72 is located directly below the drill rod 11; when the end of the fastening bolt 9 is screwed into the other limiting groove, the workbench 72 is located on the side away from the drill rod 11. Therefore, the provision of the fastening bolt 9 can improve the stability of the mounting block 7 after the position is adjusted.

[0042] Reference Figure 1 A limiting ring 73 is fixedly connected to the outer wall of the mounting block 7 on the side away from the workbench 72. The limiting ring 73 and the mounting block 7 are located at the same height. The limiting ring 73 is a circular ring, and the axis of the limiting ring 73 is vertically arranged. Therefore, after the columnar workpiece 10 is placed in the limiting ring 73, the limiting ring 73 can limit the top of the columnar workpiece 10 to prevent the columnar workpiece 10 from tipping over during the fixing process, thereby improving the safety of the operation process.

[0043] The implementation principle of a liftable drilling machine in an embodiment of the present application is as follows: in the initial state, the workbench 72 is located below the drill rod 11, a smaller workpiece is placed on the top surface of the workbench 72, and the workpiece is located between the two clamping plates 81, the double-headed screw 83 is rotated to make the two clamping plates 81 approach each other, the workpiece is clamped and fixed, and then the workpiece is drilled through the drill rod 11.

[0044] When it is necessary to drill a longer cylindrical workpiece 10, the cylindrical workpiece 10 can be placed on the inner side of the limiting ring 73 first; then the fastening bolt 9 is unscrewed and the mounting block 7 is rotated so that the limiting ring 73 is rotated to the bottom of the drill rod 11. At this time, the bottom end of the cylindrical workpiece 10 and the top surface of the base 2 are against each other, and the top end of the cylindrical workpiece 10 is located in the limiting ring 73; then the end of the fastening bolt 9 is screwed into the limiting groove to fix the mounting block 7; then the locking bolt 3 on the base 2 is rotated so that the end of the locking bolt 3 is against the outer wall of the cylindrical workpiece 10 to fix the bottom end of the cylindrical workpiece 10 on the base 2; then the position of the base 2 is adjusted by rotating the first screw 42 and the second screw 52, ​​thereby adjusting the position of the cylindrical workpiece 10 relative to the drill rod 11. After the adjustment is completed, the top end of the cylindrical workpiece 10 can be drilled through the drill rod 11.

[0045] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application.
