Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a splash protection structure for a metal chip crusher. Background Technology

[0002] Machine tools are machines used to manufacture machines, also known as machine tools or machine tools. They are generally classified into metal cutting machine tools, forging and pressing machine tools, and woodworking machine tools. In modern mechanical manufacturing, there are many methods for processing mechanical parts: in addition to cutting, there are casting, forging, welding, stamping, extrusion, etc. However, parts with high precision requirements and fine surface roughness requirements generally need to be finally processed by cutting methods on machine tools.

[0003] Patent publication number CN210306965U discloses a device for preventing metal chip splashing on a cutting machine tool, including a machine tool body and a control switch. The right side of the front of the machine tool body is fixedly connected to the back of the control switch. This utility model relates to the field of cutting machine tool technology. This device for preventing metal chip splashing on a cutting machine tool has an annular plate fixedly connected to the left side of the inner wall of the working chamber via a mounting block. Fan-shaped nozzles are fixedly connected to the inner wall of the annular plate, with the surface of the fan-shaped nozzles forming a 30° angle with the inner wall of the annular plate. The fan-shaped nozzles are arranged at equal angles about the central axis of the annular plate, and there are eight sets of fan-shaped nozzles. An annular water tank is opened inside the annular plate, forming an annular water curtain using the fan-shaped nozzles. This effectively prevents metal chips generated during cutting from splashing. In addition, the cutting fluid not only reduces the temperature of the metal block during cutting but also ensures the cleanliness of the metal block surface and improves the visibility of the cutting process, resulting in good practical effects.

[0004] However, the metal shavings in this patented invention are collected by filtering through a waste shavings collection frame. The metal shavings are easy to get stuck in the mesh of the waste shavings collection frame. Since the metal shavings are relatively small and sharp, operators are easily scratched by the metal shavings stuck in the mesh when cleaning them. Utility Model Content

The top surface of the support frame 27 has two sets of positioning grooves 28 perpendicular to it. Each positioning groove 28 has a positioning block 29 inserted into it. The bottom surfaces of the magnetic mesh 26 and the rectangular frame 30 are both vertically fixed with positioning blocks 29.

[0027] The cooling component includes a liquid pump 18 horizontally fixed in a water tank 5. The output end of the liquid pump 18 is connected to a delivery pipe 3, which is a flexible hose. The delivery pipe 3 passes through the water tank 5. A through groove 2 connected to the processing chamber 7 is opened on the top surface of the main body 1. The delivery pipe 3 moves through the through groove 2. The end of the delivery pipe 3 is connected to a hollow plate 17. The bottom surface of the hollow plate 17 is vertically connected to a nozzle 15. A screw sleeve 19 and a guide sleeve 20 are fixed on both sides of the hollow plate 17, respectively. A threaded rod 14 is threaded through the screw sleeve 19.

[0029] A magnetic mesh 26 is installed on the top surface of the support frame 27, and a rectangular frame 30 is attached to the outer edge of the magnetic mesh 26. A filter cloth 6 is fixedly connected to the top surface of the rectangular frame 30 and covers the top surface of the magnetic mesh 26. This allows the metal shavings collected by the water tank 5 to remain outside the filter cloth 6, preventing the metal shavings from getting stuck in the pores of the magnetic mesh 26. As a result, there is no need to clean the magnetic mesh 26; only the rectangular frame 30 containing the filter cloth 6 needs to be cleaned. This avoids the operator being scratched by metal shavings stuck in the pores of the magnetic mesh 26 when cleaning the magnetic mesh 26. At the same time, it automatically cleans the metal shavings adhering to the processing chamber 7, eliminating the need for manual cleaning and reducing the workload of the operator. It also prevents metal shavings in the processing chamber 7 from splashing into the operator's eyes when cleaning the metal shavings in the processing chamber 7, thus ensuring the operator's personal safety.

[0030] Working Principle: During operation, the workpiece is clamped in the processing chamber 7. Then, the pump 18 delivers coolant from the water tank 5 to the hollow plate through the delivery pipe 3. The coolant in the hollow plate is sprayed out through the nozzle 15. Simultaneously, the drive motor drives the threaded rod 14 to move the hollow plate, adjusting the position of the nozzle 15. The coolant sprayed from the nozzle 15 forms a water curtain, effectively preventing metal cutting waste from splashing. The coolant mixed with metal chips falls onto the slope 8 of the processing chamber 7. After the workpiece in the processing chamber 7 is processed, the electric push rod 21 pushes the support plate 10 towards the drain port 4. The support plate 10 drives the scraper 9 to scrape the iron chips remaining on the slope 8 towards the drain port 4. Under the action of the slope 8, as the distance between the slope 8 and the scraper 9 increases, the spring 22, which is in a compressed state, will gradually return to its original position, so that the end of the scraper 9 always abuts against the slope 8, and the iron chips will pass through the drain port 4. The iron filings fall onto the top surface of the filter cloth 6. Under the magnetic force of the magnetic mesh 26, the iron filings will be attracted to the filter cloth 6. The coolant will return to the water tank 5 through the gap between the magnetic mesh 26 and the filter cloth 6. After the iron filings on the ramp 8 are cleared, the scraper 9 returns to its original position. When the scraper 9 returns to its original position, it will gradually rise under the action of the ramp 8, while the spring 22 is compressed. When it is necessary to clean the iron filings in the water tank 5, simply pull the filter cloth 6 and the rectangular frame 30 upwards so that the filter cloth... After the iron filings on the filter cloth 6 are separated from the top surface of the magnetic mesh 26, the magnetic force on the filter cloth 6 will disappear, causing the filter cloth 6 to loosen. Then, the filter cloth 6 can be turned upside down to shake off the iron filings. This prevents the metal filings from getting stuck in the pores of the magnetic mesh 26, thus eliminating the need to clean the magnetic mesh 26. Only the rectangular frame 30 containing the filter cloth 6 needs to be cleaned. This also avoids the operator being scratched by the metal filings stuck in the pores of the magnetic mesh 26 when cleaning the magnetic mesh 26.
