[0014] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0015] Example 1

[0016] See also Figure 1 This embodiment proposes a horizontal drilling machine, including a base 1, a tool feeding mechanism 2 and a dividing chuck 3.

[0017] A plurality of anchor mounting positions 11 are provided at the bottom of the base 1 for fixing to the ground by anchor bolts.

[0018] The tool feeding mechanism 2 and the indexing chuck 3 are both fixed to the upper surface of the base 1 , and an iron chip discharge groove 12 is also provided on the upper surface of the base 1 .

[0019] The tool feeding mechanism 2 is provided with a tool holder 5, which is used to clamp the drill bit. The tool feeding mechanism 2 is used to drive the tool holder 5 to rotate, move the wings of the tool holder 5 up and down, and move horizontally back and forth toward the indexing chuck 3. The tool feeding mechanism 2 can completely use existing technical products, and such mechanisms are commonly found in machine tools such as milling machines and lathes. It should be specially stated that the structural requirement is that the axis of the indexing chuck 3 is vertically arranged, and the axis of the tool holder 5 and the axis of the indexing chuck 3 are located in the same plane.

[0020] During specific processing, the workpiece 4 is placed on the indexing chuck 3 and clamped, and then the position is adjusted by the indexing chuck 3, and then the position of the tool holder 5 in the vertical direction is controlled by the tool feeding mechanism 2. After adjustment, the tool holder 5 is controlled to move horizontally by the tool feeding mechanism 2 until a hole of the expected size is drilled on the workpiece 4. The iron filings withdrawn by the drill will fall directly into the iron filing installation groove. If multiple holes need to be processed, the workpiece 4 can be processed again by rotating it directly with the help of the indexing chuck 3. The use of the indexing chuck 3 directly ensures the accuracy of the angle of the workpiece 4 relative to the drill bit, and only one clamping is required no matter how many holes are processed. In this way, the clamping and calibration links during processing save a lot of steps, improve the processing efficiency, and at the same time ensure the accuracy, which is suitable for mass production.

[0021] It should also be noted that the movement of the tool holder 5 and the rotation of the indexing chuck 3 can be controlled semi-automatically or fully automatically, or even modified to be manually controlled.

[0022] Example 2

[0023] This embodiment proposes a horizontal drilling machine. Compared with Embodiment 1, this embodiment aims to illustrate a preferred structural form of the tool feeding mechanism 2, and other contents are the same as those of the embodiment.

[0024] The tool feeding mechanism 2 includes an X-axis saddle 21, a Y-axis slide 23 and a column 22. The X-axis saddle 21 is fixed to the upper surface of the base 1, the column 22 is slidably connected to the X-axis saddle 21 in the horizontal direction, and the Y-axis slide 23 is slidably connected to the column 22 in the vertical direction. A lead screw mechanism is provided between the column 22 and the X-axis saddle 21 and between the column 22 and the Y-axis slide 23 to drive the movement. The lead screw mechanism belongs to the conventional prior art, which necessarily includes a motor and a lead screw, and can be adjusted based on the actual situation during application and installation.

[0025] The X-axis saddle 21 includes two mounting feet 211 and two guide rails 213. The guide rails 213 are parallel to the mounting feet 211 and are located directly above the mounting feet 211. The guide rails 213 are correspondingly connected to the mounting feet 211 through connecting ribs 212, and a vertical rib 214 is provided between the two connecting ribs 212, and a screw mounting hole is provided on the vertical rib 214.

[0026] The bottom of the column 22 is provided with a slide rail groove, which cooperates with the guide rail 213 to realize the sliding connection between the column 22 and the X-axis slide saddle 21. It is further connected to the screw through the screw mounting hole, and then the screw is driven by the motor. At the same time, the column 22 is threadedly connected to the screw, so that the column 22 can be driven to move.

[0027] A vertically extending dovetail slide 221 is provided on the side of the column 22, and a matching dovetail slide groove is provided on the Y-axis slide 23. The dovetail slide 221 and the dovetail slide groove cooperate to achieve a sliding connection, and provide sufficient constraints to make the Y-axis slide 23 slide only in the vertical direction. Furthermore, a groove 222 is provided in the middle of the dovetail slide 221. By providing a motor and a lead screw in the groove 222, and connecting the Y-axis slide 23 to the lead screw, the Y-axis slide 23 can be driven to move up and down.

[0028] Furthermore, the tool holder 5 and the power device for driving the tool holder 5 to rotate are both arranged on the Y-axis slide 23 .
