Description

Technical Field

[0001] This invention relates to the field of machine tool milling head technology, and more specifically, to a machine tool milling head with a dual-output crank structure. Background Technology

[0002] In modern machining industry, machine tools, as the mother machines, directly determine the quality of the final product and production efficiency through their performance and precision. The milling head, as one of the key components of a machine tool, undertakes various machining tasks such as cutting, milling, and drilling. Its design and performance have a crucial impact on the stability, precision, and machining range of the machining process.

[0003] Traditional milling heads for machine tools typically employ a single output axis design. This design often proves inadequate when dealing with complex curved surfaces or workpieces requiring multi-angle machining. To achieve multi-angle machining, it's usually necessary to adjust the workpiece position or change milling heads with different angles. This not only increases auxiliary time and reduces production efficiency but can also introduce positioning errors due to multiple clamping operations, affecting machining accuracy. Furthermore, traditional milling heads often employ a split structure, with components fixed together by bolts or other connectors. Under prolonged high-load operation, this structure is prone to loosening and wear, affecting overall stability and service life. With the rapid development of manufacturing, especially in aerospace, automotive manufacturing, and mold processing, the demand for high-precision and high-efficiency machining is increasing, and traditional milling heads can no longer meet the needs of modern machining. Summary of the Invention

[0028] By adopting a modular design, the components are relatively independent and easy to disassemble and replace. This design not only facilitates the daily maintenance and upkeep of the machine tool milling head, but also provides users with flexible upgrade options.

[0029] Working Principle: The connecting flange 2 is fixedly connected to the machine tool head end through the mounting through-hole 201 on its top surface, ensuring a stable and reliable connection. Then, the mounting flange 202 is horizontally mated to the bottom surface of the connecting flange 2 and fixed in a stacked manner with bolts, forming a stable mounting base. The transmission flange 203 is installed on the inner side of the mounting flange 202, ensuring that the transmission flange 203 can rotate smoothly through the stabilizing bearing 206. Next, the input shaft gear 207 is fixedly sleeved onto the shaft of the transmission flange 203, ensuring that the input shaft gear 207 and one of the transmission gear assemblies 6 are in gear engagement to transmit power to the machine tool spindle. Simultaneously, the input shaft cover 208 is installed to seal the gap between the transmission flange 203 and the mounting flange 202, preventing the entry of cutting fluid and impurities. The bottom end cover 3 is fixed to one end opening of the elbow housing 1 with bolts, ensuring a good seal between the bottom end cover 3 and the elbow housing 1. Subsequently, the bottom shaft 302 is inserted into the inner center of the bottom cover 3 and fixedly connected to the inner side of the elbow housing 1 via the support bearing 307, ensuring smooth rotation of the bottom shaft 302. An output gear 306 is fixedly sleeved on the outer side of the bottom shaft 302, ensuring that the output gear 306 maintains meshing with another member of the transmission gear assembly 6 to transmit power to the bottom shaft 302. According to processing requirements, multiple transmission gear assemblies 6 are arranged horizontally in a parallel, equidistant, I-shaped pattern on the inner side of the elbow housing 1. Each transmission gear assembly 6 includes components such as a main transmission gear shaft 601, a transmission gear body 602, a transmission spacer 603, and a sealing ring body 604. Through the meshing action of the transmission gear body 602, multiple transmission gear assemblies 6 are connected into a single transmission system, achieving step-by-step power transmission. The top plate 501 is bolted to the top surface of the top flange 5, and the top shaft 502 is rotatably connected to the inner side of the top plate 501. Since the top spindle 502 and the bottom spindle 302 share the same spindle structure, no additional power transmission components are required. An internal hexagonal screw 503 is fixed to the bottom of the top spindle 502 for clamping and adjustment using a special tool. The selected milling head is installed at one end of the bottom spindle 302 via the through slot 303 and the edge fitting slot 304, ensuring a stable and reliable installation. Subsequently, the machine tool is started for no-load testing to check the operation of each component and for any abnormal noises or vibrations. After testing, actual machining operations can begin. The position and angle of the milling head are adjusted via the machine tool control system according to the shape and size requirements of the workpiece. Driven by the machine tool spindle, power is transmitted through the input shaft gear 207 to the transmission gear assembly 6, and then from the transmission gear assembly 6 to the bottom spindle 302 and the top spindle 502, ultimately driving the milling head to cut the workpiece. Because the milling head of this machine tool has a dual output function, it can complete the machining of multiple surfaces in one clamping, which greatly improves machining efficiency and accuracy.
