Problems solved by technology
However, on the one hand, the cost of the traditional full CNC gear hobbing machine is high; on the other hand, single-side processing is used in the common gear processing, and the unbalanced force causes the machine tool to vibrate greatly, and the lack of driving force of the motor leads to poor processing of large-module gears.

Embodiment Construction
[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0020] refer to figure 1 , a gantry double-hob symmetrical CNC gear hobbing machine driven by a super-large oil motor, comprising a gantry bed 1, a compression module 30 is installed on the upper middle part of the gantry bed 1, and a rotary table 14 is installed on the lower middle part of the gantry bed 1, The rotary table 14 communicates with the first hydraulic station 8 through the first hydraulic oil pipe 7, and the left hobbing module 31 installed on the left sliding column 4 and the right hobbing module 28 installed on the right sliding column 23 are symmetrically arranged on the gantry bed respectively. The inner left and right sides of body 1.
[0021] refer to figure 2 and image 3 , the gantry bed 1 is horizontally and horizontally installed with a first guide rail 2 and a second guide rail 37 on the upper left side inside the bed, and a third...

An ultra high oil-motor-driven gantry double-hob symmetrical numerical control gear hobbing machine comprises a gantry lathe body. A press module is installed at the upper end of the middle of the gantry lathe body, a rotating work table is installed at the lower end of the middle of the gantry lathe body, a left hobbing module installed on a left sliding column and a right hobbing module installed on a right sliding column are symmetrically arranged on the left side and the right side in the gantry lathe body respectively, the gantry lathe body is of a left-right symmetrical gantry structure, and the right sliding column and the left sliding column can improve the stress condition and improve feeding stability. An oil motor is adopted as a driving unit to conduct driving. Compared with a common servo motor, the oil motor can provide large output torque to meet the requirement of the large gear hobbing machine. The double-hob symmetrical cutting structure can overcome the shortcoming that a workpiece shaft is unbalanced in stress due to single-hob cutting in the traditional gear hobbing process, workpiece shaft swinging is reduced, the machining accuracy is improved, and the machining efficiency is improved in a multiplying mode.
Description
technical field [0001] The invention belongs to the field of gear cutting and processing equipment, and in particular relates to a double hob symmetric numerical control gear hobbing machine driven by a super-large oil motor. Background technique [0002] With the increasing demand for gear hobbing machines, domestic enterprises involved in gear hobbing machine manufacturing are increasing day by day. As we all know, gears are the most basic mechanical transmission components, which are in great demand and widely used. The gear machine tool is recognized by the machine tool industry as one of the products with the highest technical content, the most parts and the most complex structure. But my country's gear manufacturing machine tool industry has been in an embarrassing situation for a long time. Domestic machine tool manufacturers are relatively backward in technology, started late, and lack independent innovation capabilities and key and core technology support. Domest...
