Description

Technical Field

[0001] This utility model relates to the field of gear hobbing machine technology, and in particular to a multi-functional gear hobbing machine for gear processing. Background Technology

[0002] Gears, as core components of mechanical transmission systems, are widely used in machinery manufacturing, the automotive industry, aerospace, and other fields. Gear machining technology mainly includes processes such as gear hobbing, gear shaping, and gear milling. These processes typically require multiple pieces of equipment and steps to complete, such as roughing, gear profile machining, and subsequent finishing. This traditional machining method requires the workpiece to be clamped and positioned multiple times between different pieces of equipment, which not only increases the complexity of manual operation but also leads to low machining efficiency and difficulty in guaranteeing machining accuracy. Especially for precision gears, such as spur gears, helical gears, bevel gears, and worm gears, existing technologies have certain limitations in high-precision, automated integrated machining.

[0003] Most existing gear processing equipment is single-function, such as dedicated gear hobbing machines or mill-turning machines, capable of performing only one type of processing task. In actual production, it needs to be used in conjunction with other equipment for auxiliary processing or post-processing of the workpiece. This mode requires frequent loading and unloading and reclamping, which can easily lead to a decrease in gear processing accuracy due to repeated positioning errors. Utility Model Content

[0004] In view of the technical problems mentioned in the background art, this utility model provides a multi-functional gear hobbing machine for gear processing.

[0005] The technical solution adopted by this utility model is: a multi-functional gear hobbing machine for gear processing, including a base, on which a power turret and a hobbing mechanism are provided. The power turret is used for turning and milling, and the hobbing mechanism is used for gear hobbing. The base is also provided with a column, and a third slide rail is fixedly connected to the outside of the column. A third slider is provided in the third slide rail, and a mounting plate is installed on the outside of the third slider. The power turret is installed on the outside of the mounting plate, and a rotating indexing plate is fixedly connected to the mounting plate. The hobbing mechanism is installed on the outside of the rotating indexing plate. Turning and milling operations are performed by the power turret, and gear hobbing operations are performed by the hobbing mechanism, so that the equipment can complete the entire process from turning and milling to gear hobbing in one clamping, without frequent unloading, loading, or changing of processes.

[0006] In one embodiment, a first slide rail is fixedly connected to the base, a first slider is slidably connected to the outside of the first slide rail, and a movable seat is fixedly connected to the outside of the first slider.

[0007] In one embodiment, a second slide rail is fixedly connected to the top of the movable base, and a second slider is provided on the outside of the second slide rail, the second slider being fixedly connected to the column.

[0008] In one embodiment, the base is further provided with a ejector pin column, a fourth slide rail is fixedly connected to the outside of the ejector pin column, a fourth slider is slidably connected to the outside of the fourth slide rail, and an ejector pin tail seat is fixedly connected to the outside of the fourth slider.

[0009] In one embodiment, an electric turntable is fixedly connected to the base, and a clamping chuck is installed at the output end of the electric turntable.

[0010] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model allows for turning and milling operations via a power turret and gear hobbing via a hobbing mechanism. This enables the equipment to complete the entire process from turning, milling, gear hobbing, drilling, and tapping in a single setup, eliminating the need for frequent unloading, loading, or process changes. This integrated advantage avoids the connection errors between stages in traditional machining processes, effectively improving machining accuracy and production efficiency. During machining, the components work collaboratively through the linkage control of the CNC system. The hobbing mechanism is responsible for high-precision gear hobbing, while the power turret flexibly changes tools to complete multiple processes such as turning, milling, drilling, tapping, and cutting off. The coordination of multi-axis movement and rotation control allows the equipment to quickly adjust the machining position and angle to adapt to the precision machining needs of different complex gears.

[0018] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0019] To address the problems existing in the background technology, this application proposes the following technical solution: a multi-functional gear hobbing machine for gear processing, including a base 1, on which a power turret 7 and a hobbing mechanism 9 are provided. The power turret 7 is used for turning and milling, and the hobbing mechanism 9 is used for gear hobbing. An electric turntable 15 is fixedly connected to the base, and a clamping chuck 5 is installed at the output end of the electric turntable 15.

[0020] The power turret 7 and the hobbing mechanism 9 are existing technologies and products, so their principles will not be described in detail here. The base 1 is also equipped with a column 2, and a third slide rail 11 is fixedly connected to the outside of the column 2. A third slider is slidably installed in the third slide rail 11, and a mounting plate 10 is installed on the outside of the third slider. The power turret 7 is installed on the outside of the mounting plate 10, and a rotating indexing plate 8 for rotation is fixedly connected to the mounting plate. The hobbing mechanism 9 is installed on the outside of the rotating indexing plate 8.

[0021] In a further design, a first slide rail 4 is fixedly connected to the base 1. A first slider is slidably connected to the outside of the first slide rail 4. A movable seat 13 is fixedly connected to the outside of the first slider. A second slide rail 6 is fixedly connected to the top of the movable seat 13. A second slider is provided on the outside of the second slide rail 6. The second slider is fixedly connected to the column 2. A ejector column 3 is also provided on the base 1.

[0022] To ensure that those skilled in the art can fully understand the technical solution, the usage method of this embodiment is as follows:

[0023] In operation, milling and turning can be performed via the power turret 7, while gear hobbing can be performed via the hobbing mechanism 9. This allows the equipment to complete the entire process from initial machining to finishing in a single setup, eliminating the need for frequent unloading, loading, or process changes. This integrated advantage avoids the connection errors between stages in traditional machining processes, effectively improving machining accuracy and production efficiency. During machining, the components work collaboratively through the linkage control of the CNC system. The hobbing mechanism 9 is responsible for high-precision gear hobbing, while the power turret 7 flexibly changes tools to complete multiple processes such as turning, milling, drilling, tapping, and cutting off. The coordination of multi-axis movement and rotation control allows the equipment to quickly adjust the machining position and angle to adapt to the complex machining requirements of different workpieces. At the same time, the design of the clamping chuck and ejector pin tailstock 12 ensures the stability of the workpiece throughout the machining process, further guaranteeing the continuity and accuracy of machining. In addition, this highly integrated design significantly reduces manual intervention between processes, shortens the machining cycle, reduces labor intensity, and reduces the scrap rate caused by clamping errors or repeated positioning. Overall, this technical solution has achieved significant improvements in processing efficiency, precision, and production consistency, providing an efficient and reliable solution for modern intelligent manufacturing.
