Translation, rotation and positioning device for working carriage of large open type heavy-load spinning equipment

The invention provides a translation, rotation and positioning device for a working carriage of large open type heavy-load spinning equipment. The translation, rotation and positioning device solves the problem that manual translation wastes time and labor when the position of the working carriage of the large open type heavy-load spinning equipment is adjusted on a lathe bed platform and the angle of the working carriage relative to a main shaft. According to the device, three sets of translation mechanisms driven by hydraulic motors are provided for a working sliding frame, and two sliding blocks of a bed body platform are hinged to two sliding blocks at the bottom of the working sliding frame to drive the working sliding frame to move. Therefore, the adjusting time can be saved, the adjusting efficiency is improved, and the production efficiency is greatly improved. 本发明提供一种大型开式重载旋压设备工作滑架平移、旋转及定位装置，解决了大型开式重载旋压设备的工作滑架在床身平台上调整位置及相对主轴的角度时人工平移费时费力的问题。该装置为工作滑架提供3套液压马达驱动的平移机构，床身平台的2个滑块与工作滑架底部的2个滑块铰接相连，带动工作滑架的移动。因
