Usually, the main motion is rotation of the drill, and the axial movement of the drill is the feed motion. The drilling machine has a simple structure and relatively low machining accuracy. It can drill through holes and blind holes. By replacing special tools, it can expand, countersink, ream holes or perform tapping and other processes.

[0003] In actual processing, it is necessary to drill holes in workpieces of different sizes or different heights. At present, when processing such workpieces, workers usually install pads or fixture fixing seats of different heights on the base of the drilling machine to raise the height, so as to facilitate the workers to drill holes in the workpiece. During the installation and fixing, multiple sets of bolts must be tightened, and the operation is cumbersome, which leads to reduced processing efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the utility model provides a stable drilling machine which is easy to lift and adjust, thereby solving the problem that when drilling holes in workpieces of different heights or thicknesses, it is necessary to screw multiple sets of bolts to install pads or clamp fixing seats of different heights on the base of the drilling machine for raising the height, which is a cumbersome operation and leads to reduced processing efficiency.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a stable drilling machine that is easy to lift and adjust, including a base 1, support blocks 2 are connected at the four corners below the base 1, a buffer pad 3 is connected below the base 1, a rubber pad 28 is connected below the support block 2, and anti-skid patterns are provided below the buffer pad 3 and the rubber pad 28. The buffer pad 3 is used to buffer the vibration impact generated by the drilling process, and the rubber pad 28 and the anti-skid patterns below the buffer pad 3 can increase the friction with the ground, thereby improving the working stability of the drilling machine.

[0022] A radial drilling platform 4 is installed above the base 1, and a workbench 5 is installed on the base 1. A hollow column 6 is connected inside the workbench 5, and a mounting plate 7 is connected inside the workbench 5. A motor 8 is installed on the mounting plate 7. The output shaft of the motor 8 is connected to a first bevel gear 9, and the first bevel gear 9 is meshedly connected to a second bevel gear 10. A threaded rod 11 is connected to the second bevel gear 10, and the threaded rod 11 is threadedly connected to a lifting column 12. The second bevel gear 10 and the threaded rod 11 are both rotatably connected in the hollow column 6, and the lifting column 12 slides in the hollow column 6. A limiting strip 23 is connected to the outer wall of the lifting column 12, and a limiting groove 24 is provided on the inner wall of the hollow column 6. The limiting strip 23 slides in the limiting groove 24. When the lifting column 12 moves, the limiting strip 23 will slide in the limiting groove 24, so that the movement of the lifting column 12 is guided and restricted by the limiting strip 23, so as to prevent the lifting column 12 from rotating together with the threaded rod 11, so that the lifting column 12 can move smoothly in the hollow column 6.

[0023] A clamp seat 13 is connected to the lifting column 12, and a connecting plate 14 is connected below the clamp seat 13. The outer wall of the connecting plate 14 is in contact with the inner wall of the workbench 5. A guide rod 25 is connected to the inside of the workbench 5. A total of four guide rods 25 are distributed inside the workbench 5 in a rectangular array. A sliding groove 26 is provided on the connecting plate 14, and a sliding hole 27 is provided on the groove wall of the sliding groove 26. The connecting plate 14 slides on the guide rod 25 through the sliding hole 27. The guide rod 25 guides the lifting and lowering of the connecting plate 14 and the clamp seat 13 to avoid the clamp seat 13 and the connecting plate 14 from tilting during movement and to prevent the connecting plate 14 from colliding with the inner wall of the workbench 5.

[0024] Slots 15 are provided on both sides above the fixture seat 13, baffles 16 are inserted in the slots 15, an observation window 17 is installed on the baffle 16, an insert plate 18 is connected to the baffle 16 below, grooves 19 are provided inside the insert plate 18 on both sides, a spring 20 is connected in the groove 19, a clamping block 21 is connected to one end of the spring 20, and clamping grooves 22 are provided on the inner walls on both sides of the slot 15, the clamping block 21 is triangular in design and is engaged with the clamping groove 22, and the baffle 16 is fixed to the fixture seat 13 by the engagement of the clamping block 21 and the clamping groove 22 to prevent the vibration generated during the drilling process from causing the baffle 16 to loosen and tip over.

[0025] The working principle of the utility model is:

[0026] The staff inserts the insert plate 18 into the slot 15. As the insert plate 18 is inserted, the outer wall of the fixture seat 13 will push the block 21 into the groove 19, so that the block 21 can compress the spring 20. When the insert plate 18 is completely inserted into the slot 15, the spring 20 rebounds and pushes the block 21 to be stuck in the slot 22, thereby fixing the baffle 16 on both sides of the fixture seat 13 to block the flying metal debris and prevent the flying debris from injuring the staff. By starting the motor 8 to rotate the first bevel gear 9, and using the engagement of the first bevel gear 9 and the second bevel gear 10 to drive the threaded rod 11 to rotate, the lifting column 12 can move along the hollow column 6 through the threaded cooperation with the threaded rod 11, thereby lifting the height of the fixture seat 13, so that the fixture seat 13 can adapt to workpieces of different sizes, and the height adjustment operation is simple and convenient, which improves the processing efficiency. When the fixture seat 13 rises, the connecting plate 14 will move together with the fixture seat 13, thereby closing the gap between the fixture seat 13 and the workbench 5.
