Double-lead-screw-driven automatic turnover numerical control rotary table

Abstract

The invention discloses a double-lead-screw-driven automatic turnover numerical control rotary table. The double-lead-screw-driven automatic turnover numerical control rotary table comprises a lathe bed, a sliding base, a working table body, a supporting plate and lead screws, the sliding base is arranged on the lathe bed in a sliding mode, the supporting plate is connected to the working table body in a sliding mode, the working table body can rotate and slide on the supporting plate, the right end of the supporting plate is hinged to a support at the right end of the sliding base, and the left end of the sliding base drives the left end of the supporting plate to move around the arc of the support through the lead screws, so that the working table body is driven to automatically turn over. The double-lead-screw-driven automatic turnover numerical control rotary table has the advantages that a servo motor is adopted to be connected to a right-angle double-output-shaft speed reducer, then a second-stage right-angle speed reducer is driven to equally transmit power to the two lead screws, then the supporting plate is driven to drive a table board of the working table body to turn over and swing around the support, the structure is stable, the synchronism property is good, the problem of automatic turnover motion of the table board of the numerical control rotary table can be solved, accurate control over the positioning precision and the repeated positioning precision in the turnover process of the working table body can be realized, multi-procedure and multi-angle machining can be realized by installing and clamping a workpiece at a time, and the machining efficiency and the machining precision of the inclined surface and an inclined hole of the workpiece are improved.

Description

technical field [0001] The invention belongs to the field of processing equipment, in particular to a dual-screw-driven automatic flip numerical control rotary workbench. Background technique [0002] With the rapid development of my country's shipbuilding industry, the requirements for the machining accuracy and efficiency of the inclined plane and inclined hole of the workpiece are getting higher and higher. The traditional processing technology adopts the CNC rotary table combined with the CNC floor milling and boring machine for cutting and processing. The rotary table has two feed movements: the longitudinal movement of the slide seat and the rotation of the table. During processing, add tooling wedges on the horizontal worktable to raise the workpiece to a required angle relative to the table, or use a hydraulic cylinder to drive the table to turn over a certain angle, but these two methods are difficult to take into account the processing efficiency and accuracy at th...
