(1) Technical field

The utility model relates to the processing technology of machining cutting fluid, in particular to a machining cutting fluid filtering device.

(2) Background technology

In the process of machining, it is usually necessary to use cutting fluid. The function of cutting fluid is to clean, prevent rust, lubricate and cool down. Impurities will cause serious problems: 1) Cause the water spray hole in the tool to be blocked or the flow of cutting fluid to be blocked, which will affect the quality of deep hole processing, such as inaccurate hole size, black skin in the hole, tool chipping, tool breakage, etc.; 2) Cause The cutting fluid deteriorates, the anti-rust performance decreases, and the service life decreases; 3) It causes damage to the machining equipment, affects continuous operation, and even causes unnecessary shutdown. At present, the cutting fluid used in deep hole processing is generally filtered by special equipment, which is not only complicated to operate and high in operation cost, but also waste filter bags will cause environmental pollution.

(3) Contents of utility model

The purpose of this utility model is to provide a machining cutting fluid filtering device with simple structure, convenient operation and low manufacturing cost in view of the above existing problems.

Technical scheme of the utility model:

A cutting fluid filtering device for machining, which is composed of a liquid reservoir, a liquid filter and an infusion pump. The liquid reservoir is a tank structure, and a partition plate is arranged in the middle of the tank body, and the left and right sides of the liquid reservoir are separated into cutting fluid storage tanks before filtering. and the filtered cutting fluid storage tank, the cutting fluid storage tank before filtration is provided with a cutting fluid inlet, and the filtered cutting fluid storage tank is provided with a cutting fluid outlet; the filter is a sealed box structure with a filter layer in the middle of the box and the filtrate The filter is divided into upper and lower parts. The filter layer is composed of orifice plate, filter paper and iron filing layer. The orifice plate is sealed and fixed with the four sides of the liquid filter box. The filter paper is laid flat on the orifice plate, and the iron filing layer is evenly distributed on the filter paper. , the upper part of the filter is provided with a filtered cutting fluid overflow port and enters the filtered cutting fluid storage tank through the pipeline, and the lower part of the filter is provided with a pre-filtered cutting fluid inlet; the infusion pump is fixed above the pre-filtered cutting fluid storage tank , the liquid inlet pipe extends into the pre-filtered cutting fluid storage tank and a filter screen is arranged at the liquid inlet pipe port, and the liquid discharge pipe of the infusion pump is connected with the pre-filtered cutting fluid inlet of the lower part of the filter.

The hole diameter of the orifice plate is 5mm, and the hole spacing is 30mm.

The working mechanism of the utility model: before filtering, the cutting fluid storage tank collects the unfiltered cutting fluid, and pumps it into the lower part of the filter through the infusion pump. It acts as a filter, and the function of the filter paper is to prevent the iron filings from leaking to the bottom of the filter tank and cause the liquid inlet pipe to be blocked. The filtered cutting fluid enters the filtered cutting fluid storage tank through the overflow port on the upper part of the filter, and is supplied to the machine through the cutting fluid outlet. Processing recycling.

The utility model has the advantages that: the device is simple in structure, convenient and practical, easy to maintain and has no environmental pollution; it can effectively prolong the service life of the cutting fluid, improve the machining accuracy of parts, reduce the failure rate of equipment, and ensure continuous production; Impurities in the liquid can be controlled within 10um, which can effectively avoid tool clogging, and is especially suitable for the production of deep hole processing.
