The center balladeur train carriage of semi-automatic back knife lathe, comprise lathe bed, lathe bed both sides are provided with mainshaft fork and the tailstock center at clamping work pieces two ends, lathe bed front end between mainshaft fork and tailstock center is provided with center balladeur train, on the balladeur train of center, offer and be suitable for the central hole that workpiece passes, crude green body knife rest is installed on the balladeur train of center, the lathe bed rear end of corresponding center balladeur train opposite side is provided with forming cutter rest, it is characterized in that, described center balladeur train is arranged on lathe bed front end by center balladeur train seat, the end face of lathe bed front end and side are fixed with respectively end face guide rail and side guide, center balladeur train slides to sit by end face slide block and side slide block respectively and is located on end face guide rail and side guide, lathe bed one side is fixed with driving center balladeur train seat along the oil cylinder of end face guide rail and side guide slip.
Adopt the semi-automatic back knife lathe of this structure, center balladeur train passes through center balladeur train seat along in end face guide rail and side guide sliding process, because end face guide rail and side guide are arranged on end face and the side of lathe bed front end, can bear vertical transverse and vertical power simultaneously, stressed more even, more stable when center balladeur train is slided, slip precision is effectively guaranteed, and improves processing turning accuracy simultaneously.
The utility model can also adopt following technical measures to solve:
On lathe bed between described mainshaft fork and tailstock center, at least two material drag frame components are installed, each material supporting rack assembly comprises fixed mount, crane and lift cylinder, fixed mount is fixed on the groove between mainshaft fork and tailstock center, crane is vertical configuration and is slidably connected on fixed mount, lift cylinder is arranged on fixed mount bottom, and drives and be connected with crane lifting; Support workpiece when this structure can realize charging, has support groove on crane.
The beneficial effects of the utility model are:
The center balladeur train carriage of semi-automatic back knife lathe of the present utility model, center balladeur train passes through center balladeur train seat along in end face guide rail and side guide sliding process, because end face guide rail and side guide are arranged on end face and the side of lathe bed front end, can bear vertical transverse and vertical power simultaneously, stressed more even, more stable when center balladeur train is slided, slip precision is effectively guaranteed, and improves processing turning accuracy simultaneously.
