A CNC Rolling Machine Tool for Torsion Shaft Tooth Root Rolling

Abstract

The invention provides a numerical control tooth root rolling machine tool for rolling machining of the tooth root of a torsion shaft. Rolling machining can be conducted on the tooth root of the torsion shaft by the numerical control tooth root rolling machine tool, and tooth root rolling machining efficiency is improved. The numerical control tooth root rolling machine tool comprises a machine tool main body, a left tip, a tooth root rolling head, a proximity switch, a torsion shaft and feeding mechanism synchronous movement structure, a numerical control indexing rotary table, a hydraulic chuck, a rotary hydraulic cylinder, an auxiliary support, a numerical control system and a hydraulic system. When the tooth root is rolled, the torsion shaft needs to be located and clamped, thereby being clamped tightly by the hydraulic chuck, and meanwhile the torsion shaft is axially located by the left tip. When the tooth root is rolled, indexing of the torsion shaft is needed, and the numericalcontrol indexing rotary table drives the torsion shaft to achieve indexing rotation. Therefore, through the numerical control rolling machine tool, numerical control rolling machining of torsion shaft splines of various models can be achieved, rolling efficiency is improved, and cost is lowered.

Description

technical field [0001] The invention relates to a numerically controlled rolling machine tool, in particular to a numerically controlled rolling machine tool used for rolling the tooth root of a torsion shaft. Background technique [0002] At present, most of the suspension devices of special vehicles adopt the torsion shaft suspension system. The torsion shaft is an important part of the suspension device of a tracked vehicle. When the vehicle is running on an uneven road, the torsion shaft elastically twists and releases energy to achieve the purpose of buffering and shock absorption. During the working process, the torsion shaft is often subjected to large stress, large strain, impact and alternating torque loads, and is prone to fatigue fracture from the tooth root, which becomes a bottleneck restricting the overall performance of the vehicle. Therefore, it is very important to improve the working performance and fatigue life of the torsion shaft. [0003] There are ma...

Problems solved by technology

At present, ordinary torsion shaft dedendum rolling machine tools have been widely used in production lines, but there are still many problems in the use process, which is not conducive to large-scale production and development of products

[0004] The main problems are as follows: (1) The indexing turntable of the tooth root rolling machine tool adopts a mechanical indexing turntable, and the indexing angle of the turntable is constant when indexing, so each tooth root rolling machine tool only Capable of rolling one type of splined torque shaft

(2) When performing tool setting on the tooth root of the torque shaft, workers need to manually set the tool, which is inconvenient to operate, low in efficiency, and there is a phenomenon of inaccurate tool setting

(3) A single-wheel rolling device is used. During the rolling process, the torsion shaft will be subject to a large radial force, which is easy to cause a large bending deformation of the torsion shaft during the rolling process, thereby affecting the rolling of the torsion shaft tooth root. pressure effect

(4) The clamping chuck of the traditional machine tool is an ordinary mechanical chuck. When the workers perform tooth root rolling processing, they use manual clamping, which cannot accurately control the clamping force and increase the labor load of the workers.

(5) Workers are required to manually lubricate and cool the machine tool and workpiece, which has the disadvantages of low efficiency, large oil pollution, and dangerous operation during processing
