Drilling, tapping, milling and boring combined numerical control machine tool with multi-workpiece processing function

Abstract

The invention relates to a drilling, tapping, milling and boring combined numerical control machine tool with a multi-workpiece processing function. The numerical control machine tool comprises an electric control system; an X-axis saddle is vertically mounted at one end of a machine tool base; a Z-axis working table is mounted on the machine tool base through a Z-axis roller linear track, and a Z-axis ball screw is matched with the Z-axis working table and is driven by a Z-axis servomotor to drive the Z-axis working table to perform a Z-axis stroke action along the Z-axis roller linear track; X-axis roller linear tracks are mounted on the inner side surface of the X-axis saddle, an X-axis working table is located on the X-axis roller linear tracks, and an X-axis servomotor is mounted on the X-axis saddle between the X-axis roller linear tracks and drives the X-axis working table to traverse along the X-axis roller linear tracks through an X-axis ball screw; and a Y-axis saddle is mounted on an upper end surface of the X-axis saddle, a Y-axis roller linear track is vertically mounted on the inner side surface of the Y-axis saddle, and a Y-axis spindle seat is located on the Y-axis roller linear track and matched with a Y-axis ball screw on the back surface of the Y-axis spindle seat.

Description

technical field [0001] The invention relates to a composite numerical control machine bed which integrates drilling, tapping, milling and boring and can process multiple workpieces at one time, and belongs to the field of rotary and horizontal machining center manufacturing. Background technique [0002] The machining centers currently on the market have large machine tools (such as 850 machine tools, length 2500mm x width 2500mm x height 2500mm), not only occupy a large area, but also consume a lot of machine tool materials. During the processing, although multiple workpieces can be installed and discharged, but It can only be processed at a single station. Different station sizes require arm-type tool change. Currently, the fastest time for arm-type tool change is 3 seconds (including positioning and electronic control return signals). Therefore, the machining center machine tool cannot improve the efficiency of quantized workpieces, and the investment (manpower, material ...

[0002] The machining centers currently on the market have large machine tools (such as 850 machine tools, length 2500mm x width 2500mm x height 2500mm), not only occupy a large area, but also consume a lot of machine tool materials. During the processing, although multiple workpieces can be installed and discharged, but It can only be processed at a single station. Different station sizes require arm-type tool change. Currently, the fastest time for arm-type tool change is 3 seconds (including positioning and electronic control return signals).

Therefore, the machining center machine tool cannot improve the efficiency of quantized workpieces, and the investment (manpower, material resources, and space) is large, the machine tool material consumption is large, the floor area is large, and the energy consumption is high, which is not conducive to environmental protection.
