Embodiment Construction

[0024] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] The invention provides a column-turning numerically controlled sector gear shaping machine which adjusts the cutting angle by turning the column.

[0026] Such as Figure 1 to Figure 3 As shown, the structure of the column-turning CNC sector gear shaping machine mainly includes: a lower bed 1; a workbench 10 for lateral movement is arranged above the front of the lower bed 1; There is a middle bed 6 which moves longitudinally; a column 7 arranged on the upper part of the middle bed 6; a main driving mechanism 70 is arranged on the top of the column 7;

[0027] The present invention is provided with column overturning mechanism 20 between middle bed 6 and column 7, and this column overturning mechanism 20 is: the front part of column 7 is hinged with the rotary hinge shaft 33 that is positioned on middle bed 6, and the rear portion of column 7...

Abstract

The invention discloses a vertical column overturn type numerical control fan-shaped gear shaper, the structure thereof mainly comprises: a lower bed body, a work bench, a middle bed body, a vertical column, a main drive mechanism, a tool carrier mechanism; a vertical column overturning mechanism is arranged between the middle bed body and the vertical column, the vertical column overturning mechanism is that: the front part of the vertical column is hinged with a rotary hinged shaft which is positioned on the middle bed body, the back part of the vertical column is hinged with an ascending and descending mechanism which is positioned on the middle bed body; and the tool carrier mechanism is hinged at the front part of the vertical column. The vertical column overturn type numerical control fan-shaped gear shaper has the advantages that: the cutting angle of a tool can be adjusted by the vertical column overturning mechanism, the gear shaper can process a fan-shaped gear with constant speed ratio or variable speed ratio which is provided with the cutting angle with the range of 0 degree to 10 degrees, the vertical column overturning mechanism is simple, the precision is high, the efficiency is high and the adjustment is convenient, thus being the easiest mode for adjusting the cutting angle. The tool carrier mechanism has good rigidness and can realize the high-speed cutting. A tool avoiding mechanism can ensure the accuracy, synchronization, no loss and no lag of the tool avoiding, and the noise is very low, which is just more than 70db.

Description

technical field [0001] The invention relates to a gear shaping machine for externally connected cylindrical gears (commonly known as sector gears) with variable tooth thickness, in particular to a column-turning numerically controlled sector gear shaping machine for processing sector teeth on rocker shafts of automobile steering gears. Background technique [0002] The gear shaper of prior art is mainly used in processing cylindrical straight tooth, internal and external gear of helical tooth. The sector gear shaping machine is specially used to process variable tooth thickness circumscribed cylindrical gears with a certain cutting angle. [0003] In the prior art, the fan-shaped gear shaping machine with full mechanical transmission is controlled by a conventional electrical system and hydraulic system. This type of machine tool usually has a complex mechanical structure, with multiple gear pairs, worm gear pairs, pulleys, cams, sprockets, shafts, etc. Most of these machin...
