Description

Technical Field

[0001] This utility model relates to the field of milling and turning technology, specifically a rotary four-direction machining spindle. Background Technology

[0002] Milling and turning is a common machining method. When machining a workpiece using a CNC machine tool, one of the cutting tool or the workpiece needs to be kept stationary while the other rotates. The two workpieces are contacted to mill the surface of the workpiece. However, when machining workpieces with triangular, square, or hexagonal axes at both ends or in a certain part, different types of cutting tools need to be changed. Since the cutting tools are clamped in the tool holder, the tool must be released from its fixation before changing it, and then fixed again after the change. This results in high labor costs and cumbersome operation, which affects the efficiency of machining operations. Utility Model Content

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] like Figure 1-4As shown in the embodiment of this utility model, a four-directional rotary machining spindle includes a frame 10, a lifting assembly 20, a rotating assembly 30, and a machining spindle 40. The lifting assembly 20 is mounted on the frame 10, and the rotating assembly 30 is located on both sides of the frame 10 near the lifting assembly 20. The machining spindle 40 is mounted on the rotating assembly 30 near the lifting assembly 20. The machining spindle 40 includes a spindle support 41, a spindle beam 42, and machining heads 43. One end of the spindle support 41 is mounted on the lifting assembly 20, and both ends of the spindle beam 42 pass through the spindle support 41 and are mounted on the rotating assembly 30. Multiple machining heads 43 are provided, and the multiple machining heads 43 are staggered on the spindle beam 42. Each machining head 43 is provided with a machining cutter head 44, and the machining cutter head 44 has a different size and type of machining edge. In this embodiment, the lifting component 20 enables the machining spindle 40 to rise and fall vertically, meeting the machining requirements at different heights. The rotating component 30 allows the machining spindle 40 to rotate around a specific axis, achieving four-way machining angle changes, greatly expanding the machining range and angle possibilities. Furthermore, the machining spindle 40 is equipped with multiple staggered machining heads 43, each equipped with machining cutter heads 44 of different sizes and types. This allows the machining spindle 40 to complete multiple different types of machining tasks at once without frequent tool or equipment changes, improving machining efficiency, reducing time lost due to tool changes, and effectively enhancing the smoothness and efficiency of the entire machining process, making it highly practical.

[0030] like Figure 3 As shown, the upper surface of the frame 10 is a hollow structure 11, and the lifting assembly 20 moves within the hollow structure 11. Lateral transmission elements 12 are provided on both sides of the frame 10. The lateral transmission elements 12 are used to drive the lifting assembly 20, the rotating assembly 30, and the machining spindle 40 in lateral transmission. In this embodiment, the hollow structure 11 provides space for the lifting assembly 20 to move smoothly up and down, achieving height adjustment. It also reduces the weight of the frame 10 to a certain extent, optimizing the overall structure. Furthermore, the lateral transmission elements 12 on both sides effectively drive the lifting assembly 20, the rotating assembly 30, and the machining spindle 40 in lateral transmission, allowing each component to cooperate in lateral movement, precisely adjusting the processing position, greatly improving processing flexibility and accuracy, better meeting the needs of different processing tasks, and improving overall processing efficiency and quality.

[0031] Two sets of lifting components 20 are provided, and the two sets of lifting components 20 are arranged opposite each other on both sides of the inner wall of the frame 10. The spindle support 41 is movably disposed between the two sets of lifting components 20.

In this embodiment, by placing the two sets of lifting transmission elements 22 on both sides of the lifting frame 21, the lifting process becomes smoother and more balanced, effectively avoiding tilting or jamming caused by uneven force on one side, thus ensuring the accuracy of the lifting action. Furthermore, the placement of the lifting drive element 23 between the two sets of lifting transmission elements 22 allows the driving force to be evenly distributed to the transmission elements on both sides, improving overall transmission efficiency, optimizing structural space, and making the entire lifting assembly 20 more compact and reasonable, reducing space occupation.

The lifting transmission element 22 is used to assist the lifting drive element 23 in driving the machining spindle 40 to perform lifting transmission. In this embodiment, the lifting cylinder 231 pushes the lifting drive rod 232, which can accurately drive the lifting drive seat 233 and the machining spindle 40 mounted on it to achieve stable lifting and lowering, meeting the needs of different machining positions. The height of the machining spindle 40 can be flexibly adjusted to improve the adaptability and flexibility of machining. The lifting transmission element 22 assists the lifting drive element 23 in working, further enhancing the reliability and stability of the lifting transmission, ensuring that the machining spindle 40 runs smoothly during the lifting process, reducing vibration and deviation, and improving machining accuracy.

The rotary spindle 32, disposed within the rotary mounting base 33, results in a compact structure and smooth operation, enabling precise control of rotational accuracy and meeting the precise requirements for angle and position during machining. The connection between one end of the spindle beam 42 and the rotary spindle 32 within the rotary mounting base 33 effectively transmits power, ensuring overall linkage. This allows the four-directional rotary machining spindle 40 to flexibly achieve multi-directional rotary machining, improving machining efficiency and quality, and adapting to complex and diverse machining needs.

The rotating bushing 322, fitted onto the rotating spindle 32, provides stable support and a smooth rotational foundation for the rotating wheel 323. The good fit between the bushing and the spindle reduces friction during operation, improves transmission efficiency, and extends the service life of the equipment.
