Milling machine structure

Abstract

The invention discloses a milling machine structure. The milling machine structure comprises a workbench mounted on a milling machine body, a collecting plate fixedly connected to the bottom of the workbench, a flushing sprayer slidably mounted on the collecting plate, and a cutting fluid purifying device connected with the flushing sprayer through a pipeline. The cutting fluid purifying device comprises a plastic box, a first tank is arranged on one side of the box, a second tank and a third tank are arranged on the box and located on one side of the first tank, and the third tank is located under the second tank. A magnetic roller is rotatably mounted in the second tank and comprises two symmetrical round-groove-shaped magnetic roller shells, a plurality of magnetic bar cavities are formed in the circumferential wall of each magnetic roller shell, and cylindrical magnetic bars are mounted in the magnetic bar cavities. A rotating shaft is mounted between two opposite side walls of the second tank, and an inner magnet used for attracting the magnetic bars to the middle portion of the magnetic roller is fixedly connected to the middle portion of the rotating shaft through a connecting plate. According to the milling machine structure, cutting fluid can be efficiently purified in an energy-saving mode, and the cutting fluid can be repeatedly used.

Description

technical field [0001] The invention belongs to a machine tool structure for mechanical processing, and in particular relates to a milling machine structure. Background technique [0002] During the working process of the milling machine, a large amount of cut iron filings will be mixed in the cutting fluid. Since the cutting fluid is recycled, it is necessary to purify the iron filings in the cutting fluid. With the improvement of machining accuracy, high-speed grinding and powerful grinding technology are developing rapidly. In addition to choosing reasonable grinding parameters, the circulation quality of grinding fluid must also be improved. Existing cutting fluid purification devices are mainly filter-type purification devices, which rely on filter media to remove impurities, such as filter screen, line gap, sheet and paper tape filters. In order to avoid the accumulation of iron filings, this filter type purification device needs to be cleaned regularly, which is very...

Problems solved by technology

[0004] The magnetic roller of the above-mentioned patent includes a magnet portion and a rubber portion, the magnet portion is distributed along 270° of the circumference of the magnetic roller, and the rubber portion is distributed along 90° of the circumference of the magnetic roller, so as to facilitate the separation of iron filings from the magnetic roller However, with such a structure, when the scraper scrapes relative to the magnetic roller, the scraper needs to push the iron filings from the magnet part to the rubber part to separate the iron filings from the magnetic roller. In this process, the iron filings and the magnet part The magnetic force between them produces greater resistance to the scraper, so the torque and power consumption required by the motor are relatively large, and the power consumption is also large

On the other hand, when the cutting fluid flows through, if it just comes into contact with the rubber part, it cannot be absorbed, that is, it is difficult to ensure the purification effect of the cutting fluid.
