Description

Technical Field

[0001] This utility model relates to the field of drilling machines, and in particular to a drilling machine that is easy to position. Background Technology

[0002] A drilling machine is a mechanical device that uses a rotating drill bit to drill holes in a workpiece. It can precisely drill holes in workpieces and is widely used in various workpiece processing applications.

[0003] However, when using drilling machines, traditional positioning structures are mostly designed with a fixed angle, which cannot achieve horizontal rotation adjustment. This makes it impossible for the positioning pressure block to adapt to the contour curve of the workpiece when processing ring-shaped or irregular workpieces, resulting in positioning blind spots. At the same time, existing technologies rely on an overall lifting mechanism or a simple screw, which lacks precise control over the adjustment of the clamping height. The adjustment process requires auxiliary tools and cannot achieve fine-tuning. Thin-walled workpieces are prone to deformation or surface damage due to overpressure. Furthermore, existing equipment integrates positioning and drilling functions into a single action sequence, lacking a separate operation mechanism. The height adjustment of the positioning structure depends on the main lifting system, which means that the pre-positioning and drilling processes cannot be carried out in parallel. Overall, it cannot adapt to the clamping and positioning requirements of workpieces of different sizes. Utility Model Content

[0004] The main objective of this invention is to provide a drilling machine that is easy to position, which can effectively solve the technical problems raised in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] As a further embodiment of this utility model, the positioning structure includes a rotating plate, a lifting mounting plate, an adjusting handle, an adjusting screw, a positioning collar, a positioning support rod, and a positioning pressure block. The rotating plate is movably mounted on the outside of the rotating mounting plate, the lifting mounting plate is fixedly mounted on the upper end of the rotating plate, the adjusting handle is movably mounted on the upper end of the lifting mounting plate, the adjusting screw is movably mounted on the lower front end of the lifting mounting plate, the positioning collar is threaded onto the outside of the adjusting screw, the positioning support rod is welded to the front outside of the positioning collar, and the positioning pressure block is fixedly mounted on the lower end of the positioning support rod.

The lifting screw 6 passes through the lifting drilling plate 7 and is threadedly connected to it. The rotating shaft of the lifting motor 5 passes downward through the mounting top plate 3 and is fixedly connected to the lifting screw 6.

[0020] Specifically, after the lifting motor 5 is running, it drives the lifting screw 6 to rotate. The rotation of the lifting screw 6 drives the lifting drill plate 7 to move up and down. The guide rail support rod 4 plays the role of positioning the lifting drill plate 7.

[0021] Please refer to this carefully. Figure 2 A motor mounting plate 10 is fixedly installed at the rear end of the lifting drilling plate 7, and a drive motor 11 is fixedly installed at the upper end of the motor mounting plate 10. The shaft of the drive motor 11 is connected to the shaft seat 8 by belt drive.

[0022] Specifically, the operation of the drive motor 11 causes the drill chuck 9 at the lower end of the shaft seat 8 to rotate. The drill chuck 9 is equipped with a drill bit for drilling.

[0027] Specifically, the position of the positioning block 22 is adjusted by rotating the rotating plate 16. Then, the adjusting handle 18 is rotated to drive the adjusting screw 19 to rotate. The rotation of the adjusting screw 19 drives the positioning collar 20 to move up and down through the threaded connection. The positioning collar 20 then drives the positioning support rod 21 and the positioning block 22 to move up and down, so that the positioning block 22 presses on the workpiece that needs to be drilled below. At the same time, the positioning blocks 22 on both sides move down to press and position the workpiece to be drilled.
