Abstract

The invention relates to a precision gang tool level bed numerically controlled lathe with a tailstock and belongs to the technical field of metal cutting machine tools. The lathe comprises a base, wherein a headstock seat and a bed are fixedly arranged on the base; a headstock unit is fixedly arranged on the headstock seat; a Z-axis linear rail and a Z-axis lead screw are fixedly arranged on the bed; a first Z-axis linear rail slide block is arranged on the Z-axis linear rail in a sliding fit manner; a middle planker is fixedly arranged on the first Z-axis linear rail slide block and connected with the Z-axis lead screw; an X-axis linear rail and an X-axis lead screw are fixedly arranged on the middle planker; an X-axis linear rail slide block is arranged on the X-axis linear rail in a sliding fit manner; a small planker is fixedly arranged on the X-axis linear rail slide block and connected with the X-axis lead screw; a multistation cutter turret is fixedly arranged on the small planker; a second Z-axis linear rail slide block is arranged on the Z-axis linear rail in a sliding fit manner; a tailstock unit is fixedly arranged on the second Z-axis linear rail slide block; and the bottom of the tailstock unit is connected with a hydraulic tailstock push cylinder. The lathe has positive significance for popularization of the numerically controlled machine tools.

Description

technical field [0001] The invention belongs to the technical field of metal cutting machine tools, and in particular relates to a CNC lathe with a tailstock and a precision-arranged flat bed. Background technique [0002] CNC lathes are commonly used machine tools in machining. Existing CNC lathes on the market with precision row tool and flat bed adopt X-axis and Z-axis linkage processing, the tool holder is fixed on the small carriage, there is no tailstock, and there is no way to process shaft parts. In addition, most of the spindles in the spindle box units of the precision row tool flat bed CNC lathes on the market directly install the bearings on the spindle box, and most of the clamping mechanisms in the spindle adopt a mechanical lever structure. The failure rate of the spindle box unit is high. Processing , The installation is difficult, the precision is low, and the life of the main shaft bearing is short. Contents of the invention [0003] Aiming at the probl...
