Cutting fluid circulating system used for ultrasonic inspection of numerical-control machine tool

Abstract

The invention provides a cutting fluid circulating system used for ultrasonic inspection of a numerical-control machine tool. The cutting fluid circulating system comprises a settler, a lifting pump, a first nozzle, a second nozzle and a fluid collection pan. A filter plate is arranged in the settler, and a settler inlet and a settler outlet are arranged in two sides of the filter plate respectively. The settler outlet is communicated with the inlet of the lifting pump through a pipeline, the outlet of the lifting pump is communicated with the first nozzle and the second nozzle respectively through pipelines, a first throttle valve is arranged on a pipeline between the lifting pump and the first nozzle, and a second throttle valve, a filter and a pressure relief valve are arranged on a pipeline between the lifting pump and the second nozzle; the fluid collection pan is arranged below a worktable of the numerical-control machine tool and used for collecting cutting fluid on the worktable of the numerical-control machine tool, and the outlet of the fluid collection pan is provided with a filter screen and is communicated with the inlet of the settler through a pipeline. The cutting fluid circulating system used for ultrasonic inspection of the numerical-control machine tool meets the machining and detecting requirements and good filtering effect of the cutting fluid.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a cutting fluid circulation system for ultrasonic testing of numerical control machine tools. Background technique [0002] In the prior art, ultrasonic waves are often used to detect workpieces processed by numerical control machine tools to determine whether there are defects inside the workpieces. Before testing, the operator needs to apply coupling fluid on the surface of the workpiece. Since the CNC machine tool itself does not have a coupling fluid supply device, although there is an intersection between the coupling fluid and the cutting fluid, the coupling fluid is replaced by cutting fluid to realize the detection of the workpiece. It works. However, ultrasonic testing has high requirements on the purity of the coupling fluid, and the cutting fluid in the cutting fluid circulation device of the machine tool itself is mixed with more impurities, w...

AI Technical Summary

Problems solved by technology

However, ultrasonic testing has high requirements on the purity of the coupling fluid, and the cutting fluid in the cutting fluid circulation device of the machine tool itself is mixed with more impurities, which cannot meet the purity requirements of the coupling fluid during ultrasonic testing.

In order to cooperate with the detection of the workpiece, the coupling liquid supply device must be equipped on the CNC machine tool, which will undoubtedly increase the manufacturing cost of the enterprise
