Gears refer to mechanical components with gears on the rim that continuously mesh to transmit motion and power. They are a key component that enables related devices to generate transmission. Gear transmission refers to a device that transmits motion and power by a gear pair. It is the most widely used mechanical transmission method in various modern equipment. Its transmission is relatively accurate, efficient, compact, reliable, and has a long service life. Gear processing machine tools are widely used in the manufacturing industry, especially in the fields of automobiles, tractors, machine tools, engineering machinery, mining machinery, metallurgical machinery, petroleum, instrumentation, aircraft and spacecraft. There are various processing methods, such as hobbing, milling, shaping, grinding, etc. Each method has its specific application scenarios and advantages; Gear processing machine tools are machine tools specially used for processing the gear parts of various cylindrical gears, bevel gears and other toothed parts.

[0019] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] A multifunctional gear machining CNC machine tool according to a preferred embodiment of the present invention will be described in detail below.

[0021] Embodiment 1, as Figure 1-Figure 9 As shown, it comprises a machine tool body 1, a workbench 2 is arranged on one side of the machine tool body 1, and a fixing component 3 is arranged inside the workbench 2; The fixing assembly 3 includes a fixing cylinder 301 arranged inside the workbench 2, the fixing cylinder 301 can rotate inside the workbench 2, a fixing plate 302 is fixedly installed on the surface of the fixing cylinder 301, a slot 303 is provided on the surface of the fixing cylinder 301, a sliding block 304 is slidably installed on the fixing cylinder 301 through the slot 303, a return spring 305 is fixedly connected between the sliding block 304 and the fixing cylinder 301, a fixing plate 306 is fixedly installed on one side of the sliding block 304, an oblique plate 307 is fixedly installed on the bottom of the sliding block 304, four groups of slots 303 are arranged in an annular shape, a matching plate 308 is provided below the oblique plate 307, and the matching plate 308 matches the oblique plate 307; A mounting plate 309 is fixedly installed on the inner wall of the fixed cylinder 301, an electric telescopic rod 310 is fixedly installed on the bottom of the mounting plate 309, a connecting block 311 is fixedly installed on the output end of the electric telescopic rod 310, a push rod 312 is fixedly installed on the top of the connecting block 311, and the push rod 312 can penetrate and extend to the top of the mounting plate 309, a sliding ring 313 is slidably installed on the surface of the fixed cylinder 301 and located below the fixed disk 302, the sliding ring 313 is fixedly connected to the connecting block 311 through a connecting rod 314, a groove is annularly provided on the surface of the fixed disk 302, and the fixed disk 302 is rotatably connected to a clamping plate 315 through the groove, a rotating member 316 is fixedly installed on the bottom of the clamping plate 315, and a linkage rod 317 is rotatably installed between the rotating member 316 and the sliding ring 313; When in use, the staff first sets the outer gear sleeve to be processed on the surface of the fixed cylinder 301, and then starts the electric telescopic rod 310. When the electric telescopic rod 310 moves upward, it will drive the connecting block 311 to move upward and reset. At the same time, when the connecting block 311 moves upward, the pushing rod 312 on the surface of the connecting block 311 pushes the matching plate 308 to move upward. When the matching plate 308 moves upward, because both the surface of the matching plate 307 and the inclined plate 307 have matching inclined surfaces, when moving upward, the matching plate 308 continues to move to push the inclined plate 307 to move outward. At the same time, when the inclined plate 307 moves, it drives the sliding block 308 to move upward. 04 slides on the inner wall of the fixed cylinder 301 and squeezes the reset spring 305 at the same time. The reset spring 305 contracts due to elastic potential energy. When the sliding block 304 expands outward, it drives the fixing plate 306 to move out of the slot 303, thereby holding the inner diameter of the outer gear against and fixing it. At this time, the staff can control the machine tool to insert the gears. When the inserting is completed, the staff only needs to control the electric telescopic rod 310 to operate in the reverse direction. At this time, the reset spring 305 loses its thrust, thereby driving the sliding block 304 to reset, causing the outer gear to lose its fixing force, making it easier for the staff to remove it. When it is necessary to insert the gears of the inner gear, the staff can The staff controls the fixed cylinder 301 to drive the fixed plate 302 to flip, so that the surface originally on the upper side rotates to the lower side. During the rotation process, the metal chips attached to the surface of the fixed plate 302 due to the toothing will fall into the inside of the workbench 2 due to the flipping of the fixed plate 302. At the same time, the staff only needs to control the electric telescopic rod 310 to push the connecting block 311 to move upward. The connecting block 311 drives the sliding ring 313 to move upward through the connecting rod 314. At this time, when the sliding ring 313 moves upward, the sliding ring 313 drives the clamping plate 315 to rotate in the groove through the linkage rod 317 and the rotating member 316. At this time, the staff The gear to be processed into an internal gear can be clamped by simply placing it between the clamping plates 315. After the processing is completed, the metal chips generated by the processing can be dumped out while the internal gear is removed in the same way, and the external gear can be processed quickly at the same time, which improves the applicability and processing efficiency of the machine tool. At the same time, the metal chips generated by the processing do not need to be manually cleaned by the staff using a brush or the like, thereby reducing the labor burden of the staff. Furthermore, when the connecting block 311 drives the sliding ring 313 to slide through the connecting rod 314, a rubber sealing pad is provided in the groove for the connecting rod 314 to slide.

At the same time, the air outlet block 7 is arranged to provide a certain support effect on the fixed disk 302 when the gear is processed, thereby improving the stability during processing.

[0023] Embodiment three, as Figure 2 and Figure 8 As shown, a connecting spring 8 is fixedly installed on one side of the connecting block 6 close to the connecting box 5, a connecting pipe 9 is fixedly connected to one side of the connecting block 6 close to the connecting box 5, a fan 10 is fixedly installed on one side of the workbench 2 close to the machine tool body 1, an output end of the fan 10 is fixedly connected to the connecting pipe 9, an air outlet hole is opened on the surface of the air outlet block 7, and the top of the air outlet block 7 is in contact with the fixed plate 302; When the fixed disk 302 flips, it contacts the surface of the air outlet block 7 and can push the air outlet block 7 to move to one side of the connecting box 5. When the air outlet block 7 moves, it squeezes the connecting spring 8 through the connecting block 6, so that the fixed disk 302 can be smoothly flipped. At the same time, after the flipping is completed, the connecting spring 8 is pushed out due to the elastic potential energy, which has a certain supporting effect on the fixed disk 302. The fan 10 is set up to continuously blow air when the fixed disk 302 flips to dump the metal chips.
