Multi-size cast gear blank machining method

Abstract

The invention discloses a multi-size cast gear blank machining method. A to-be-machined gear is placed in the center of a gear containing table (15), a control shaft (2) on the left side and a rotating shaft (4) are adjusted to appropriate positions, a round blade (19) on a first machine head (1) is used for cutting the interior of the to-be-machined gear, a cylindrical vertical through hole is formed, rectangular waste chippings which are cut off are placed into a waste chipping collecting device (14) below the gear containing table (15), after protruding blocks at the two ends of a hiding strut (16) are upwards moved, the protruding blocks are rotated clockwises, the hiding strut (16) is fixed, the gear with the machined interior is placed on the hiding strut (16) which extends out, thena second machine head (17) at the right end is used for cutting the gear, after cutting is carried out on time, a rotating rod (9) is rotated, cutting is carried out, the steps are sequentially carried out, and accurate cutting of the gear is completed. The multi-size cast gear blank machining method has the advantages that the gear can be quickly completed, and the gear machining efficiency is improved.

Description

technical field [0001] The invention relates to a processing device, in particular to a processing method for multi-size casting gear blanks. Background technique [0002] A gear is a mechanical element with gears on the rim that continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of generative gear cutting method and special machine tools and cutting tools using this principle appeared one after another. With the development of production, the stability of gear operation was paid more attention. [0003] The existing gear processing method is to process the gears in several steps, using a variety of processing devices, and transporting the gears during the process, which greatly takes up the processing time and reduces the processing efficiency of the gears. The scattering of metal scraps easily damages the processing blades and increases the processing cost. At the...

[0003] The existing gear processing method is to process the gears in several steps, using a variety of processing devices, and transporting the gears during the process, which greatly takes up the processing time and reduces the processing efficiency of the gears. The scattering of metal scraps can easily cause damage to the processing blade and increase the processing cost. At the same time, the gear processing requires a high degree of precision. The general processing method has a low pass rate and wastes raw materials.
