Numerical control rack gear milling machine

Abstract

The invention relates to a numerical control rack gear milling machine. A Z-direction tool body (1) and an X-direction tool body (14) are spliced into a T shape, and a large X-direction dragging plate (12) is movably arranged above the X-direction tool body (14). An X-direction roll ball screw rod (17) is arranged in the X-direction tool body (14), and an X-direction servo motor (15) is arranged on the right side of the X-direction tool body (14). An X-direction synchronous rack belt wheel (13) is connected between the X-direction servo motor (15) and the X-direction roll ball screw rod (17), and an X-direction roll ball screw rod nut (23) is fixedly arranged on the large X-direction dragging plate (12), and the X-direction roll ball screw rod nut (23) can move left and right on the X-direction roll ball screw rod (17). A press screw nail (11) is arranged above the large X-direction dragging plate (12), and parts such as a Z-direction dragging plate (3), a small Y-direction dragging plate (4), and the like are arranged in the mode similar to that of the parts in the X direction. A numerical control system (16) is fixedly arranged on the tool body (14). Compared with the prior rack machine, the numerical control rack gear milling machine obviously improves the indexing accuracy, has the advantages of automatic cutting, automatic indexing and low labor intensity, and greatly saves the labor cost.

Description

technical field [0001] The invention relates to a gear milling machine, in particular to a numerically controlled rack gear milling machine. Background technique [0002] The existing rack machine is transformed from a milling machine. According to the racks of different modulus, the ratio of the hanging wheels is calculated, and the indexing is driven by the hanging wheels. The labor intensity is high, the efficiency is low, the indexing accuracy is poor, and the processing length is limited. . At present, the diameter of milling cutters of similar machine tools of many domestic manufacturers is about 180 mm, which not only increases the difficulty of cutting, but also increases the cost of using the cutters. Contents of the invention [0003] The technical problem to be solved by the invention is: aiming at the above shortcomings of the same kind of machine tools of many domestic manufacturers at present, to provide a kind of indexing which utilizes a numerical control ...
