Problems solved by technology

Existing vertical lathes include left and right columns, beams that reciprocate up and down along the guide rails of the left and right columns, vertical tool rests that reciprocate and horizontally move along the beam guide rails, workbench devices and control systems. Due to the weight factor in the process of rising and falling, the load contrast between rising and falling is large, and the requirements for the column screw are relatively high, which affects the service life of the machine tool

Abstract

The invention discloses a double-post vertical lathe, which comprises a rotating worktable device, two upright posts, a crossbeam which performs reciprocating movement up and down along guide rails of the upright post, and a vertical tool post which performs reciprocating movement along a guide rail of the crossbeam, wherein a hydraulic balancing cylinder device of the crossbeam is arranged beside the upright posts and comprises hydraulic balancing cylinders of the crossbeam which are respectively positioned at the middle parts of the two upright posts, each hydraulic balancing cylinder of the crossbeam comprises a balancing cylinder base fixed on the ground, a cylinder sleeve and a piston in the cylinder sleeve, and the upper end of the cylinder sleeve is fixedly connected with the crossbeam through a fixing part. The double-post vertical lathe adopts the structure to reduce the load contrast during the ascending and descending process of the crossbeam, thereby ensuring that the performance of a machine tool is steadier, prolonging the service life of the machine tool, and reducing maintenance cost; and the double-post vertical lathe reduces processing cost, and a worktable has good kinematic accuracy and larger load resistant capability.

Description

technical field [0001] The invention relates to a lathe, in particular to a double-column vertical lathe. Background technique [0002] The double-column vertical lathe can be used for large motors, large pump valves, transportation, shipbuilding and engineering machinery industries, such as disc and cylindrical parts, such as motor casings, pump valve casings, wheel hubs, etc. Surface, grooving and other turning processing, vertical tool holder pull for turning the inner and outer tapered surface. Existing vertical lathes include left and right columns, beams that reciprocate up and down along the guide rails of the left and right columns, vertical tool rests that reciprocate and horizontally move along the beam guide rails, workbench devices and control systems. Due to the weight factor in the process of rising and falling, the load contrast between rising and falling is large, and the requirements for the column screw are relatively high, which affects the service life o...
