The distribution box controls the equipment circuit, and the machining operation is realized through the spindle handle and the front control panel of the spindle.

[0064] Example 2

[0065] This embodiment takes the positioning process as an example. If a hole needs to be machined at point A on the workpiece, the operation steps are as follows:

[0066] S1: Loosen the locking of the rotary sliding component 4, and rotate the guide beam 421 to make the main shaft roughly aligned with the circumferential direction where point A is located;

[0067] S2: Adjust the height of the main shaft of the lifting, rotating and sliding component 4 to the plane where point A is located;

[0068] S3: Loosen the locking mechanism of spindle assembly 5, and move spindle assembly 5 to precisely align the spindle with point A;

[0069] S4: Lock the rotary sliding assembly 4 and the spindle assembly 5, and begin machining.

[0070] It should be noted that radial drills can perform various hole machining processes by changing the cutting tools and adjusting the motion parameters:

[0071] Drilling: Install a twist drill, the spindle rotates at high speed (main motion), and at the same time the spindle feeds (feed motion) into the workpiece to form a through hole or blind hole.

[0072] Reaming: Enlarging an existing hole using a reamer. The spindle speed is lower than that of a drill, and the feed rate is larger to improve the dimensional accuracy and surface quality of the hole. Boring: The reamer feeds along the existing hole wall while the spindle rotates at a low speed. Micro-cutting improves the hole's accuracy (e.g., IT7-IT9 grade) and surface roughness (Ra1.6-3.2μm). Countersinking: Machining the end face, countersunk hole, or boss of a hole using a countersink. The spindle rotates at a low speed with a uniform feed rate to ensure a flat end face or perpendicularity to the hole axis. Tapping: Installing a tap, the spindle alternates between forward and reverse rotation (controlled by a reversing handle) while simultaneously feeding manually or automatically to achieve internal thread machining. The spindle speed and feed rate need to be adjusted according to the thread pitch.

[0073] This invention controls positioning accuracy by using a locking mechanism to rotate the sliding assembly 4 and the spindle assembly 5, eliminating mechanical backlash and preventing hole position deviations caused by component movement during machining. For high-precision holes, a dial indicator or scribing can be used for auxiliary positioning. Cutting parameters are matched by selecting appropriate speed and feed rate based on the workpiece material (e.g., steel, cast iron, aluminum) and tool type to avoid tool wear due to excessive speed or tool breakage due to excessive feed rate. Workpiece clamping typically involves fixing the workpiece to the base or worktable using pressure plates and bolts to ensure no displacement during machining, especially for large workpieces which require uniform clamping to prevent vibration.

[0074] It should be noted that the working principle of a radial drilling machine is essentially to achieve three-dimensional spatial positioning and cutting motion of the spindle through mechanical transmission. Its core advantages lie in its flexible multi-position machining capabilities and intuitive manual operation. Although traditional radial drilling machines rely on manual adjustment, their structural design enables efficient machining of large and multi-hole workpieces, making them an indispensable hole-machining equipment in machining. Modern CNC radial drilling machines have incorporated CNC systems to further enhance automated positioning and precision control capabilities, while the fundamental mechanical principles remain unchanged.

[0075] As can be seen from the above description, the advantages of this utility model are:

[0076] 1. The telescopic rotary radial drill of this utility model has a wide processing range, strong applicability, and multi-hole processing capability. It can process vertical holes at different positions and heights on the same plane without frequent workpiece movement.

[0077] 2. The telescopic rotary radial drill of this utility model is easy to operate, suitable for manual and flexible adjustment, mechanical transmission, real-time controllability, suitable for single-piece and small-batch production or repair scenarios, and has strong adaptability to complex working conditions without the need for complex programming.

[0078] 3. The telescopic rotary radial drill of this utility model has a stable structure, good rigidity, strong mechanical durability, and flexible positioning method.

[0079] 4. The telescopic rotary radial drill of this utility model has low cost, convenient maintenance, low equipment purchase cost, simple maintenance, and readily available spare parts;

[0080] 5. The telescopic rotary radial drill of this utility model is suitable for the processing needs of specific scenarios, such as on-site processing of large workpieces.

[0081] 6. The telescopic rotary radial drilling machine of this utility model has high processing flexibility, simple operation, low cost and durable structure. It is especially suitable for single-piece and small-batch production, large workpiece processing, multi-position hole system processing and scenarios with low requirements for CNC technology. Although it is not as automated and precise as modern CNC machine tools, its cost performance and practicality make it still occupy an important position in the field of mechanical processing. It is an ideal choice for small and medium-sized enterprises to achieve diversified hole processing.

[0082] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
