Description

Technical Field

[0001] The utility model relates to the technical field of gear milling machines, and particularly relates to a gear milling machine for machining spiral bevel gears. Background Technique

[0002] Spiral bevel gears, namely spiral bevel gears, are commonly used for the movement and power transmission between two intersecting shafts. The teeth of bevel gears are distributed on the surface of a conical body, and their tooth profiles gradually decrease from the large end to the small end. When machining spiral bevel gears, a gear milling machine needs to be used for operation. The gear milling machine adopts numerical control technology and is a finishing equipment for machining high-precision gears. There are certain drawbacks in the existing gear milling machines for machining spiral bevel gears. During the machining process of spiral bevel gears, certain debris will be generated, and the debris falling on the surface of the gears affects the working accuracy of the gear milling machine. Moreover, it takes time to clean up after the gear milling machine finishes working. Before machining, the gears are mostly fixed by screws, and the operation is cumbersome. Therefore, we propose a gear milling machine for machining spiral bevel gears. Content of the Utility Model

A first driving motor 303 is fixedly installed on the upper surface of the bottom plate 304. A first motor shaft 306 is fixedly installed on one side surface of the first driving motor 303. A fan blade 302 is sleeved and installed on the surface of the first motor shaft 306 near the middle position. A milling tooth blade 301 is sleeved and installed on the surface of the first motor shaft 306 near one side; The base 2 and the milling tooth structure 3 are fixedly installed on the upper surface of the outer frame 203 near one side through the electric hydraulic rod 305. The slider 307 is embedded and installed inside the sliding groove 205. The slider 307 plays an auxiliary supporting role for the bottom plate 304, which is beneficial to alleviating the load-bearing pressure of the electric hydraulic rod 305; The fixing structure 4 includes a second motor shaft 401, a second driving motor 402, a fixing plate 403, a milling tooth table 404, a fixing column 405, a first nut 406, a second nut 407, and a fixing groove 408. Fixing grooves 408 are formed on the upper surface of the fixing plate 403 near the front and rear positions, and there are two groups of fixing grooves 408. A second driving motor 402 is fixedly installed on the upper surface of the fixing plate 403. A second motor shaft 401 is fixedly installed on the upper surface of the second driving motor 402. A milling tooth table 404 is fixedly installed on the upper surface of the second motor shaft 401.

The debris generated during the processing is collected inside the base 2; the gear body 1 is placed above the gear milling table 404, so that the gear body 1 is sleeved on the surface of the fixing column 405, and is tightened and fixed by the first nut 406 sleeved on the surface of the fixing column 405. The electric hydraulic rod 305 is started, and the height of the bottom plate 304 is adjusted by the electric hydraulic rod 305. When the bottom plate 304 moves, the slider 307 moves inside the chute 205, so as to adjust the height of the first driving motor 303. The gear milling table 404 drives the second motor shaft 401 to rotate through the second driving motor 402. After the adjustment is completed, the gear body 1 can be processed by the gear milling blade 301. When the first motor shaft 306 rotates, it drives the fan blade 302 to rotate, thereby generating wind. The wind blows away the debris generated during the processing of the gear body 1. Under the blocking action of the protection plate 201, it reaches the inside of the outer frame 203 through the plate groove 202, and is separated by the partition plate 207, and the wind is discharged by the filter screen 204. When the position of the second driving motor 402 needs to be adjusted, loosen the second nut 407, move the fixed plate 403 inside the outer frame 203, so that the fixing groove 408 moves on the surface of the fixing screw 206, and after adjusting appropriately, tighten and fix the second nut 407.
