Description

Technical Field

[0001] The invention relates to the technical field of chip removal for milling machines, and more specifically to a chip removal device for numerically controlled milling machines. Background Art

[0002] CNC milling machine is also called CNC milling machine, which means a milling machine controlled by electronic digital signals. CNC milling machine is an automatic processing equipment developed on the basis of general milling machine. The processing technology of the two is basically the same, and the structure is somewhat similar. CNC milling machine is divided into two categories: without tool magazine and with tool magazine. Among them, CNC milling machine with tool magazine is also called machining center. CNC milling machine is a CNC machine tool with strong processing function. The rapidly developed machining center and flexible machining unit are all produced on the basis of CNC milling machine and CNC boring machine. Both of them are inseparable from milling method. Since CNC milling process is the most complicated and the technical problems that need to be solved are the most, people have always focused on milling processing when researching and developing CNC systems and automatic programming language software. In the work of CNC milling machine, a large amount of metal debris will be generated when processing workpieces. The general treatment method is to use brushes and other tools to clean and Collect, so as to facilitate the normal operation of subsequent equipment, among which, the existing patent with publication number: CN211966796U discloses a CNC milling machine with a chip removal device, including a CNC machine case, a spindle box is arranged at the bottom of the CNC machine case, a spindle is arranged at the bottom of the spindle box, a column is arranged on the left side of the CNC machine case, a milling machine base is arranged at the bottom of the column, a workbench is arranged on the right side of the upper surface of the milling machine base, a chip removal base is arranged on the right side of the milling machine base, a dust collecting cylinder is arranged on the left side of the upper surface of the chip removal base, a negative pressure bin is arranged on the right side of the dust collecting cylinder, a negative pressure pipe is arranged on the right side of the negative pressure bin, a negative pressure device is arranged on the right side of the negative pressure pipe, two dust suction pipes are arranged at the bottom of the left side of the dust collecting cylinder, and suction cups are threadedly connected to the inner sides of the two dust suction pipes. The patent adds an electromagnet to the wall of the dust collecting cylinder, so that a large amount of iron filings are adsorbed on the wall of the dust collecting cylinder, thereby increasing the use space of the dust collecting cylinder and preventing a large amount of iron filings from clogging the filter screen, so that the negative pressure device cannot complete its work normally.

[0003] However, there are still some shortcomings in its actual use, such as: the current cleaning method is irregular and inefficient. In the process of processing batches of workpieces, the equipment needs to be stopped repeatedly to clean the debris before the next part can be processed. This process is not only cumbersome and inefficient, but also has a certain degree of danger. When cleaning the debris, the operator is likely to ignore the position of the cutter head and be scratched. At the same time, there are many dead corners on the machine tool workbench, and the cleaning process is difficult to reach every corner, causing some debris to accumulate in the dead corners of the workbench for a long time, thereby polluting the inside of the milling machine and forming stubborn dirt. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a chip removal device for a CNC milling machine. By setting a jet cleaning component, a guide component and a collection component, and utilizing the mutual cooperation of the components, first, the operator drives the air pump to open, so that it passes the high-pressure gas through the gas collecting pipeline, and finally ejects the high-speed gas through the jet head, so that the gas passes through the fixed table and the surface of the workpiece and the support platform, so that the metal debris remaining in the gaps and surfaces is blown to the other side through one side of the support platform, and finally attracted by the adsorption magnetic plate, thereby completing the cleaning of the metal debris. Then the operator pushes the side of the connecting square plate, so that it slides horizontally on the guide rail, thereby synchronously driving the movable side plate connected to the bottom end of the square plate to slide on the surface of the adsorption magnetic plate, and is tightly attached to the surface of the adsorption magnetic plate through the strip adapter, so that the metal debris adsorbed on the surface of the adsorption magnetic plate is scraped off, and moved toward the inner side of the fixed frame. The metal debris on the support platform is removed by the guide plate, and the debris on the work platform is cleaned up in time without restarting the CNC milling machine, thereby further improving its work efficiency. By setting a V-shaped guide plate, a side guide plate and a bevel back plate, and utilizing the cooperation of the V-shaped guide plates, the air pump is driven to first pass the high-speed gas through the surface of the V-shaped guide plate to narrow it, thereby accelerating the flow of gas, and then continuing to guide the gas through the side guide plate, so that the gas passes through the fixed table and the surface of the workpiece and the support platform, thereby blowing the metal debris remaining in the gap and on the surface through one side of the support platform to the other side, thereby completing the gas guidance and output work on the V-shaped guide plate, further facilitating the gas to blow out the debris on the platform, improving the cleaning efficiency of the equipment for the debris and the coverage rate of the gas on the surface of the support platform, so as to solve the problems raised in the above-mentioned background technology.
