Description
技术领域technical field
本发明涉及数控车床传动技术领域，具体涉及一种数控车床横向进给传动机构。The invention relates to the technical field of numerically controlled lathe transmission, in particular to a transverse feed transmission mechanism of a numerically controlled lathe.
背景技术Background technique
随着我国车床技术的成熟，数控车床也发展较为迅速。丝杆传动机构广泛应用于数控机床等领域。现有丝杆传动机构中电机与传动丝杆通常轴心位于同一直线安装，电机电轴直接带动传动丝杆转动。传动丝杆正反旋转时，受力在一个轴心方向，受安装积累误差影响和电机传动震动影响，传动丝杆所需要的绝对精度较高。With the maturity of lathe technology in our country, CNC lathes are also developing rapidly. Screw drive mechanism is widely used in CNC machine tools and other fields. In the existing screw drive mechanism, the motor and the drive screw are usually installed on the same straight line, and the electric shaft of the motor directly drives the drive screw to rotate. When the transmission screw rotates positively and negatively, the force is in the direction of one axis. Due to the influence of the accumulated installation error and the vibration of the motor transmission, the absolute accuracy required for the transmission screw is relatively high.
在大型数控机床进给系统中，进给驱动机构对整个进给系统精度、刚度的影响非常大。目前的机床横向进给机构在保证大行程的同时就无法保证刚性，并且体积大，传动效率低。In the feed system of large CNC machine tools, the feed drive mechanism has a great influence on the accuracy and stiffness of the entire feed system. The current lateral feed mechanism of the machine tool cannot guarantee the rigidity while ensuring a large stroke, and has a large volume and low transmission efficiency.
因此，针对上述问题，本发明提出了一种新的技术方案。Therefore, aiming at the above problems, the present invention proposes a new technical solution.
