Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, specifically a drilling machine. Background Technology

[0002] A drilling machine is a mechanical processing device used to drill holes in metal or other materials. It is mainly used in machining and home decoration. It mainly uses the high-speed rotation of the drill bit to drill holes in the surface of the material to obtain the desired material. However, existing drilling machines cannot meet the requirements of inclined drilling, which greatly reduces the applicability of existing drilling machines and makes them unable to meet the processing needs of different methods.

[0003] To address the aforementioned issues, Chinese patent CN219402455U, a hydraulic drilling machine for easy angle adjustment, describes a design using a support plate, hydraulic telescopic cylinder, rotating shaft, first gear, U-shaped mounting plate, motor, and second gear. Starting the motor causes its shaft to rotate, driving the second gear, which in turn drives the first gear, thus rotating the rotating shaft. This rotation of the rotating shaft, in turn, causes the hydraulic telescopic cylinder to deflect, facilitating angle adjustment during drilling for creating angled holes. While this patent allows for angle adjustment, it only adjusts the angle of one surface, failing to provide dual adjustment for both front / back and left / right angles, and thus cannot meet diverse processing requirements.

[0004] Therefore, in order to achieve dual-angle adjustment and meet the adjustment requirements of front-back and left-right angle surfaces, a drilling method is proposed to overcome the problems existing in the above-mentioned prior art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drilling machine that solves the problem that existing drilling machines cannot achieve dual adjustment of the front-back and left-right angle surfaces.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling machine, comprising a base worktable, a thickened column, and a driving drilling structure. The thickened column is mounted on the upper surface of the base worktable. The driving drilling structure is mounted on the upper surface of the thickened column. An angle adjustment structure capable of multi-angle adjustment is mounted on the surface of the thickened column. The angle adjustment structure comprises an adjustment structure and a clamping structure. The adjustment structure includes a movable bracket mounted on the surface of the thickened column. A clamping bolt is provided on the surface of the movable bracket. An adjustable flange is mounted on the right end face of the movable bracket. A fixing bolt is provided between the movable bracket and the adjustable flange. An adjusting bolt passes through the surface of the adjustable flange, and a square opening passes through the upper surface of the adjustable flange. An internal tooth is provided on the inner side of the square opening. The adjusting bolt passes through the square opening and has an external tooth on its surface. The external tooth and the internal tooth form a gear connection. A first mounting plate is installed on the surface of the adjustable flange, and a worktable is movably installed on the first mounting plate. The upper end of the curved adjusting plate is movably connected to the lower end of the worktable. A clamping structure for clamping the workpiece is installed on the upper end of the worktable. A bolt is provided on the rear side of the adjustable flange, and the bolt can pass through the square opening and contact the surface of the curved adjusting plate.

[0007] Furthermore, the thickened column surface is provided with a standard line, which is on the same plane as the vertical center line of the movable bracket, and an angle scale line is provided on the surface of the left end of the adjustable flange.

[0008] Furthermore, the drive drilling structure includes a spindle box mounted on the upper end of the thickened column, a servo motor mounted on the left end face of the spindle box, a first transmission pulley mounted on the output end of the servo motor, a shaft mounted on the right side inside the spindle box, a second transmission pulley mounted on the upper end of the shaft, the second transmission pulley and the first transmission pulley being driven by a transmission belt, a drill chuck mounted on the lower end of the shaft, a drill bit mounted on the lower end of the drill chuck, and an operating handle capable of controlling the downward movement of the drill bit on the rear side of the spindle box.

[0009] As a preferred technical solution, the clamping structure includes a second mounting plate symmetrically mounted on the upper end of the workbench, with a threaded shaft penetrating the surface of the second mounting plate, and a clamping plate mounted on the inner end of the threaded shaft.

[0010] Furthermore, the curved adjustment plate has angle scale lines on its surface, and the curved adjustment plate is curved in shape.

[0011] Compared with the prior art, the present invention provides a drilling machine with the following advantages:

[0012] 1. This drilling machine first allows for the rotation and adjustment of the adjustable flange on the movable support. By comparing the scale line on the left end surface of the adjustable flange with the standard line on the thickened column, the adjustable flange is adjusted to a suitable angle. Then, the adjusting bolt is rotated to adjust the position of the curved adjusting plate through the engagement of the internal and external teeth. Finally, the curved adjusting plate is fixed with bolts. Through the above structure, this drilling machine achieves angle adjustment on both the left and right and front and rear angle planes, thus solving the problem that existing drilling machines cannot achieve dual adjustment of the front and rear and left and right angle planes.
