Gantry numerical-control milling and grinding integrated lathe of fixed column and movable beam type

Abstract

The invention discloses a gantry numerical-control milling and grinding integrated lathe of a fixed column and movable beam type, comprising a lathe bed (2), a worktable (3), a left column (17), a right column (14), a beam (6), a spacing beam (22), a top beam (13), an electrical cabinet (33), a system control panel (32) and a tool clamp. The beam (6) is arranged on the left column (17) and the right column (14) through a beam-driving device, a boring and milling head (4) and a universal grinding head (41) are respectively arranged on the beam (6), the boring and milling head (4) is driven by a boring and milling head left-and-right driving device and a boring and milling head up-and-down driving device, the universal grinding head (41) is driven by a grinding head left-and-right driving device and a grinding head up-and-down driving device, and the worktable (3) is arranged on the lathe bed (2) through a ball screw pair (34). On the lathe, after once clamping, a workpiece can be processed by milling, boring, drilling, grinding, rigidly tapping and other continuous working procedures with high accuracy.

Description

technical field [0001] The invention relates to a numerical control machine tool, specifically a fixed-column movable beam type gantry numerical control milling-grinding integrated machine tool, which is mainly used for numerical control processing of various complex precision parts such as various basic large parts, box-shaped parts, and plate parts. technical background [0002] CNC machine tool is the abbreviation of computer numerical control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process control codes or other programs that comply with the instructions, and decode them, so that the machine tool can move and process parts. The CNC machine tool has the following characteristics: high processing accuracy, stable processing quality, and can be Multi-coordinate linkage can process parts with complex shapes. When the processed parts are changed, generally only the NC program needs to be changed...

AI Technical Summary

Problems solved by technology

The current shortcomings of CNC machine tools are: 1. Rack and pinion transmission: complex structure, high cost, low precision; Auxiliary transmission: For long distances, it is difficult to add support in the middle, because the screw is deflected under its own weight, which makes it impossible to work, and it is in point contact when it works, which is easy to form a fatigue layer, short life, and limited carrying capacity
