Technical Field
[0001] This utility model relates to the field of chair processing and production technology, and in particular to a precision CNC machine tool for grooving chair legs. Background Technology
[0002] A precision chair leg grooving CNC machine tool is a machine tool used for high-precision grooving of chair legs. It combines CNC technology and precision machining processes, enabling it to precisely cut grooves of various shapes and sizes into the chair leg material according to a pre-set program. In modern manufacturing, the machining accuracy of precision chair legs directly affects the quality and stability of the chair. With continuous technological advancements, the precision requirements for chair leg machining are becoming increasingly stringent. Traditional grooving methods are insufficient to meet the demands of high-precision, high-efficiency production.
[0003] In existing technologies, traditional CNC machine tools for grooving chair legs employ a CNC system. Operators input specific requirements for grooving the chair legs, such as the shape (rectangular, trapezoidal, arc, etc.), dimensions (depth, width, length), and position of the groove, into the CNC system via programming. The CNC system then generates corresponding control signals based on these instructions. These control signals drive the motor, causing the cutting tool to move along a specific path and gradually cut into the material to a set depth, performing precision grooving.
[0004] However, in the existing technology, traditional precision chair leg grooving CNC machine tools usually require manual placement of the chair legs inside the fixture for alignment during loading. Manual placement is prone to positional misalignment, resulting in poor processing accuracy and affecting product quality. Therefore, a precision chair leg grooving CNC machine tool is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a precision chair leg grooving CNC machine tool, which aims to improve the problem of poor machining accuracy in the prior art.

The sliding plates 10 are plate-shaped and adapt to the alignment of chair legs of different lengths by sliding. Two rotating screws 11 are threadedly connected inside the base 1. The rotating screws 11 generate a spiral progression by rotating, pushing the sliding plates 10 to slide. Multiple guide tubes 12 are slidably connected inside the sliding plates 10. The guide tubes 12 are cylindrical, driving the subsequent structure to slide smoothly. A positioning plate 13 is fixedly connected to the outside of the guide tubes 12. The positioning plate 13 is plate-shaped and pushes the chair leg to the outside of the subsequent structure for alignment. A motor 14 is fixedly connected inside the sliding plates 10, and the motor 14 is used for driving... The positioning plate 13 provides power for movement. The drive end of the motor 14 is fixedly connected to the turntable 15, which is disc-shaped and rotates under the drive of the motor 14. The top of the turntable 15 is rotatably connected to the rotating bar 16, one end of which is driven by the turntable 15 to make a circular motion. The rear side of the base 1 is fixedly connected to the electric slide rail 2, which is used to drive the grooving structure to move horizontally and process multiple chair legs at the same time. The outside of the electric slide rail 12 is slidably connected to the sliding seat 3, which is used to provide an installation base for the subsequent grooving structure and cleaning components. The interior of the sliding seat 3 is equipped with a cleaning component for blowing away grooving debris.
[0033] Reference Figure 1 and Figure 3 The rotating bar 16 is externally rotatably connected to the outside of the positioning plate 13, thereby pushing the positioning plate 13 to produce reciprocating motion. After being limited by the guide tube 12, it drives the positioning plate 13 to produce smooth sliding. The two rotating screws 11 are externally rotatably connected to the outside of the sliding plate 10. By rotating the screws 11, the sliding plate 10 is pushed to slide, adjusting the spacing of the positioning. Multiple electric sliding grooves 8 are fixedly connected to the top of the base 1. A clamping seat 9 is slidably connected to the top of the electric sliding grooves 8. The electric sliding grooves 8 and the clamping seat 9 are used for... The base 1 has a fixed plate 7 fixedly connected to its top, which acts as a fixed fulcrum to provide a positioning and fixing point for the chair legs. Multiple electrically operated sliding grooves 4 are fixedly connected to the outside of the sliding seat 3. These grooves control the up-and-down sliding of the grooving structure. A sliding seat 5 is slidably connected to the outside of the sliding grooves 4. A drill bit 6, which is a slender cylindrical shape, is fixedly connected to the bottom of the sliding seat 5. The function of the drill bit 6 is to drill holes and create grooves during the chair leg processing.
[0034] Reference Figure 1 and Figure 4The cleaning component includes a second motor 17, which is externally fixedly connected to the inside of a sliding seat 3. The second motor 17 is the core power source of the cleaning component. A turntable 18 is fixedly connected to the drive end of the second motor 17. The turntable 18 is also disc-shaped and is driven by the second motor 17 to rotate. A protruding button 21 is fixedly connected to the top of the turntable 18. The protruding button 21 is driven by the turntable 18 to perform circumferential motion. A rocker arm 19 is rotatably connected inside the sliding seat 3. An air nozzle 20 is fixedly connected to the front side of the rocker arm 19. The air nozzle 20 is a long and thin tube with an open front end for spraying airflow to blow away debris. The inside of the rocker arm 19 is in contact with the outside of the protruding button 21. Through the circumferential motion of the protruding button 21, it contacts the inside of the rocker arm 19, thereby driving the rocker arm 19 to perform reciprocating rocking motion. An air pump 22 is fixedly connected to the outside of the sliding seat 3. The function of the air pump 22 is to generate high-pressure airflow to provide power to the air nozzle 20. An air pipe 23 is fixedly connected to the bottom of the air pump 22. The other end of the air pipe 23 is fixedly connected to the outside of the air nozzle 20. The air pipe 23 is a long and thin tube, with one end connected to the air pump 22 and the other end connected to the air nozzle 20. The function of the air pipe 23 is to deliver the airflow generated by the air pump 22 to the air nozzle 20. The bottom of the rocker arm 19 is in contact with the top of the turntable 18.
[0035] Working principle: First, the operator places the chair leg on top of the clamping seat 9. Then, the rotating screw 11 is turned to drive the sliding plate 10 to slide inside the base 1. After adjusting to a suitable distance, the power switch of motor 14 is turned on, causing the turntable 15 to rotate. This causes the rotating bar 16 to generate a reciprocating force, which drives the positioning plate 13 and multiple guide tubes 12 to slide inside the sliding plate 10. This pushes the chair leg against the outside of the fixing plate 7 for alignment and positioning. Finally, the switch of the clamping seat 9 is turned on to clamp and fix the chair leg. The electric slide rail 24 drives the sliding seat 2 5 to slide downward, causing the drill bit 6 to contact the chair leg to perform drilling and grooving operations. The motor 14 drives the positioning plate 13 to push and align the chair leg before fixing it, thus improving the accuracy of drilling and grooving and improving product quality.
[0036] Secondly, by turning on the air pump 22, airflow is delivered through the air pipe 23 to the inside of the air nozzle 20. The air nozzle 20 blows away the processing debris from the grooving process for cleaning. Then, the motor 2 17 is turned on. The drive end of the motor 2 17 rotates, causing the turntable 2 18 to rotate, which in turn causes the top protrusion 21 to rotate, thereby causing the contact rocker arm 19 to reciprocate. This causes the air nozzle 20 to generate an oscillating airflow, which evenly and comprehensively blows away the debris, reducing the accumulation in dead corners. This achieves efficient cleaning of the processing debris from the grooving process. Furthermore, the oscillation of the airflow achieves complete coverage of the processing area, ensuring thorough cleaning.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
