A CNC machine tool with stable use and high precision

Abstract

The invention discloses a numerical control machine tool with stable use and high precision. The numerical control machine tool comprises a machine tool body, an air gun connector, a workbench and abase, wherein the workbench is arranged inside the machine tool body, and the base is arranged at the bottom end of the machine tool body; a cooling box is arranged inside the base, and a water outletpipe is arranged at the bottom of one end of the cooling tank in a penetrating manner; the top end of a partition plate is connected with a mounting bottom plate in a welding manner; and a pluralityof peristaltic pumps are arranged at the top end of the mounting bottom plate at equal intervals, and a suction hose is arranged at one ends of the peristaltic pumps. The numerical control machine tool is scientific and reasonable, and safe and convenient to use; and cutting fluid of a cooling tank is sucked through the peristaltic pumps, so that the liquid level on one side of the partition plateis kept at a stable height all the time, so that when the pumps pull out and suck the cutting fluid through a water inlet pipe, the cutting fluid pressure on the pumps is always kept consistent, andthe change of cutting fluid spraying rate is reduced, thus the influence of the cutting fluid pressure on the machining precision of the machine tool is avoided, and the machining precision of the machine tool is indirectly improved.

Description

Technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a numerically controlled machine tool with stable use and high precision. Background technique [0002] CNC machine tool is the abbreviation of digital control machine tool. It is an automatic machine tool equipped with a program control system. It can logically process a program with control codes or other symbolic instructions, decode it, and express it with coded numbers. The information carrier is input to the numerical control device, and after arithmetic processing, the numerical control device sends out various control signals to control the action of the machine tool, and automatically process the parts according to the shape and size required by the drawing. The numerical control machine tool mainly includes the processing program carrier, the numerical control device, and the servo And the measurement feedback system and the main body of the machine tool. The m...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a stable and high-precision CNC machine tool, which can effectively solve the problem in the above-mentioned background technology. The existing CNC machine tool extracts the cutting fluid in the cooling box through a pump, and the cutting fluid is sprayed at the processing position, while the cutting fluid is used. When the cutting fluid level drops in the cooling box, it will cause the cutting fluid ejection rate to change, resulting in a decrease in the machining accuracy of the machine tool. When adding the cutting fluid, adding too fast or too slow will also cause cutting fluid The ejection rate changes, which in turn affects the machining accuracy of the machine tool
