Description

Technical Field

[0001] This utility model relates to the field of tapping technology, specifically to a single-axis servo tapping device. Background Technology

[0002] In many industrial sectors such as machinery manufacturing and hardware processing, tapping (i.e., machining internal threads) is an indispensable basic process. Traditional tapping operations mostly rely on manual tapping or semi-automatic mechanical tapping equipment, which is not only labor-intensive and inefficient, but also makes it difficult to guarantee consistent product quality.

[0003] While some existing tapping devices have improved automation and machining accuracy to a certain extent, they still suffer from several technical bottlenecks. For example, their complex structures and insufficient coordination between motion axes can lead to errors during long-stroke, multi-position tapping processes, affecting thread quality. Furthermore, conventional tapping devices often lack effective protective measures, allowing debris and coolant generated during processing to splash out, polluting the working environment and potentially damaging precision transmission components, thus reducing the equipment's lifespan.

[0004] Therefore, to address the above issues, it is necessary to design a single-axis servo tapping device with precise control and excellent protection performance to solve the problems of insufficient positioning accuracy, high flexibility, and poor protection performance in the existing technology, and to meet the needs of modern precision manufacturing for high efficiency and stability.

[0021] This utility model provides, for example Figure 1-4The single-axis servo tapping device shown includes a frame 1, which is a rectangular frame structure with support feet 24 at the four corners of its bottom for stable placement of the device. A processing table 20 is fixedly installed on the top of the frame 1 for clamping workpieces and machining internal threads. The processing table 20 is surrounded by an upwardly extending protective cover 21, which is a concave plate structure with transparent glass embedded in its center to facilitate observation of the machining process and effectively block debris and coolant splashes.

[0022] A first lead screw 3 is longitudinally installed inside the frame 1. One end of the lead screw 3 is connected to the output end of the first motor 2 fixed on the outside of the frame 1. A first slide block 4 is fitted on the first lead screw 3. The first slide block 4 and the first lead screw 3 form a lead screw drive through ball bearings. A first slide rail 5 is provided on each side of the upper surface of the frame 1. A slide plate 6 is slidably connected on the first slide rail 5. The slide plate 6 is L-shaped. Its horizontal section is fixedly connected to the first slide block 4, and its vertical section extends upward and supports both ends of the protective shell A7, so that the protective shell A7 is suspended above the frame 1.

[0023] A second lead screw 9 is horizontally installed inside the protective shell A7. One end of the second lead screw 9 is connected to the output end of the second motor 8 fixed on the side of the protective shell A7. A second slide block 10 is fitted on the second lead screw 9. The second slide block 10 is driven by the second lead screw 9 through ball bearings. Two horizontally arranged second slide rails 11 are also provided inside the protective shell A7. The two ends of the second slide block 10 are slidably engaged with the second slide rails 11. The upper surface of the second slide block 10 is fixedly connected to the back of the protective shell B12.

[0024] A third lead screw 14 is vertically installed inside the protective shell B12. The upper end of the third lead screw 14 is connected to the output end of the third motor 13 fixed on the top of the protective shell B12. A third slide block 15 is fitted on the third lead screw 14. The third slide block 15 and the third lead screw 14 form a lead screw drive through ball bearings. A third slide rail 16 is provided on each side inside the protective shell B12. The two ends of the third slide block 15 are slidably connected to the third slide rail 16. A fixing block 17 is installed on the front surface of the third slide block 15. A fourth motor 18 is fixed above the fixing block 17. The output shaft of the fourth motor 18 passes downward through the fixing block 17 and is connected to the upper end of the tapping spindle 19. A tap is installed at the lower end of the tapping spindle 19 and is directly facing the workpiece to be processed position on the processing table 20.

[0025] A control console 23 is provided on one side of the frame 1, which can independently control the start, stop, speed and direction of the first motor 2, the second motor 8, the third motor 13 and the fourth motor 18.

[0026] Working principle: First, the machining parameters and coordinate positions are input through the control console 23. The first motor 2 drives the first lead screw 3 to rotate, which drives the first slide 4 to move longitudinally along the first slide rail 5. Thus, the slide plate 6 drives the entire horizontal and vertical moving unit to adjust its position longitudinally. The second motor 8 drives the second lead screw 9 to rotate, which causes the second slide 10 to move laterally along the second slide rail 11. This drives the protective shell B12 and the tapping spindle 19 to be positioned laterally. The third motor 13 drives the third lead screw 14 to rotate, which causes the third slide 15 to move vertically along the third slide rail 16. This adjusts the height position of the tapping spindle 19.

[0027] Once the tapping spindle 19 is positioned above the hole to be machined on the workpiece, the fourth motor 18 starts and drives the tapping spindle 19 to rotate. At the same time, the third motor 13 controls the tapping spindle 19 to move downwards for tapping according to the set program. After tapping is completed, the third motor 13 reverses and lifts the spindle, the fourth motor 18 stops rotating, and each servo motor moves to the next processing position or returns to the initial position according to the program.
