Abstract

The invention provides a direct driving type rotary transverse moving device, which comprises a rotary moving part, a transverse moving part and a signal transmission control part, wherein a wireless electric power transmission unit is used for supplying electricity to a linear motor driving controller, and in addition, position feedback units of the transverse moving part are respectively positioned on a rotary table top and rotate along with the rotation of a rotary table, so the linear motor cannot be wound by a power supplying power supply wire in the rotating process of the rotary table or cannot be wound by a feedback data wire. In addition, the device adopts a wireless network for realizing the communication between the linear motor driving controller and a main control system, and the winding of various kinds of cables is further avoided, so the complete direct driving of the linear motor without any winding on the rotary table top is realized, and good application prospects are realized.

Description

technical field [0001] The invention relates to a rotary translation device for automation equipment, in particular to a direct drive rotary translation device. Background technique [0002] In order to achieve radial precision linear motion on the rotary table, the existing rotary translation table technology uses an indirect drive method of a rotating motor and mechanical transmission parts (such as gears, leadscrews, etc.) on the rotary table to achieve radial linear motion. Although this indirect drive method can achieve precise linear motion with a certain accuracy, the mechanical transmission parts are easy to reduce the reliability and transmission efficiency of the system, and there are mechanical wear and mechanical gaps, and mechanical wear or fatigue failure will often limit the life of the system. maintain. In some precise occasions, this indirect driving method requires extremely high-precision mechanical transmission parts, which often have high costs and limi...
