Description

1227685 V. Description of the invention (1) Technical field to which the invention belongs The present invention relates to an automatic gear hobbing machine and an application method thereof, in particular to a composite module of an automatic gear hobbing machine and a sharpener suitable for gear cutting and an application method thereof. Previous technologies: Song wheels (cylindrical, conical, stern wheel pair), threads, screws, worms, and screws are the key transmission parts and mechanical elements in the machinery manufacturing industry. Their manufacturing process and product quality directly affect the various types of machinery. Assembly quality, such as aviation, aerospace, weapons, ships, electronics, textile machinery, petrochemicals, transportation, railways, light industry, automobiles, motorcycles, construction machinery, metallurgy and mining, machine tools, tools, instruments, meters, construction machinery, general Machinery, lifting and transportation machinery, agricultural machinery and printing machinery. These mechanical designs are complex, but the manufacturing technology and equipment of gears and other parts have great commonalities. This type of mechanical parts with many variations can be completed by a gear processing machine. Gear machining machines are machines that process various spur gears, bevel gears and other toothed parts. There are various specifications of gear processing machine tools, including those that process gears with a diameter of a few millimeters; large-scale machine tools that process gears with a diameter of more than ten meters, as well as high-efficiency machine tools for mass production and high-precision machine tools that process precision gears. The gear hobbing machine included in the gear processing machine is an indispensable part. The so-called gear hobbing machine (gear hobbing machine) refers to a gear cutting machine that uses the generative method to cut gears. It uses hob cutting to obtain gears. It is generally suitable for cutting helical gears, spur gears, and worm gears. . common

1227685 V. Description of Invention (2) The hobbing machine uses a hob to roughen and finish machining straight teeth, helical gears, herringbone gears and worm gears, etc., with a wide processing range and high precision production. However, the traditional gear hobbing machine must be calculated manually and then matched with the gear to calculate its cutting angle. When a gear with a specific modulus, number of teeth, spiral angle and lead quantity is to be manufactured, it must be processed through the following steps: (a) Use the matching changes of the gear or the inverter to complete the tool rotation speed. (b) Use the gear calculation of the first gearbox to obtain the required number of teeth. (c) Calculate the lead using the gears of the second gearbox. (d) First use the spiral formula and the calculation results of the machine itself, then look up the table to get the desired gear train, and use the gear train of the third gear box with the gear to get the desired helix angle. It can be known from the above method that the conventional gear hobbing machine needs to use at least three gear boxes to complete, and the time it takes is quite complicated. In addition, the conventional gear hobbing machine also needs to use various gear formulas to calculate manually, and it also needs to match the gears of the gear box. Such a processing method can only be calculated by a skilled engineer with a long-term training. In addition, in terms of the accuracy of the helix angle in degrees, minutes, and seconds, the more precise (for example, calculation to the second), the more difficult it is to calculate. It can be seen that the traditional technology still has many disadvantages in the following aspects:

1227685 V. Description of the invention (3) (1) Operating surface: The conventional technology requires manual calculation and then gear matching to calculate its cutting angle. (2) In terms of education and training: operators need to undergo long-term education and training courses to perform meter checking and so on. (3) In terms of pre-operation time: After the mold is calibrated, it still needs to calculate the required value through manual calculation and matching with the gears. (4) In terms of production capacity: As the conventional technology requires complicated operations, the production capacity is poor, for example, about 1 per minute. (5) In terms of quality: Since it needs to be calculated by manual look-up tables and formulas, the accuracy can only be measured in units of one hundredth of a millimeter. (6) Industrial safety: personnel need to operate and monitor on site. (7) Environmental protection: The conventional technology has a large amount of noise during operation and will cause water pollution. In addition, a large amount of cutting oil fume can also cause air pollution in the environment. (8) Application: The conventional technology cannot perform the grinding correction of the sharpener on the same machine. Therefore, how to develop a composite module of an automatic hobbing machine and a grinding machine that can avoid the above-mentioned disadvantages and improve the production efficiency is an urgent problem that needs to be solved at present.
