[0003] The machining table surface of CNC machine tools is generally equipped with grooves. During milling, chips often fall into these grooves, making them difficult to clean. Traditional manual cleaning is not only inefficient but also increases the workload. Therefore, a CNC machine tool milling chip cleaning device is proposed to solve the aforementioned problems.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides the following technical solution:

[0023] Example 1

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A CNC machine tool milling chip cleaning device includes a machine tool body 1 and a worktable 2, and a cleaning component 3 is provided on the worktable 2;

[0025] The cleaning assembly 3 includes an electromagnet 31, a connecting plate 32 fixedly connected to the bottom of the electromagnet 31, a cleaning brush 33 fixedly connected to the bottom of the connecting plate 32, a collection frame 34 placed on the rear side of the machine tool body 1, a servo motor 35 fixedly connected to the machine tool body 1, a threaded rod 36 fixedly connected to the output shaft of the servo motor 35, a threaded cylinder 37 threadedly connected to the outer side of the threaded rod 36, and a limit block 38 fixedly connected to the threaded cylinder 37.

[0026] The worktable 2 is fixedly connected to the machine tool body 1. The worktable 2 has a groove, and the cleaning brush 33 extends into the groove on the worktable 2. The connecting plate 32 is made of metal.

[0027] The groove design on the workbench 2 allows the cleaning brush 33 to be precisely embedded, avoiding cleaning dead corners; the metal connecting plate 32 not only enhances the structural strength, but also uses the electromagnet 31 to magnetically attract iron filings, improving cleaning efficiency.

[0028] A mounting bracket is fixedly connected to the rear side of the machine tool body 1, and a collection frame 34 is placed inside the mounting bracket. The inner wall of the collection frame 34 on the side closest to the machine tool body 1 is designed to be inclined.

[0029] The card holder secures the collection box 34 to prevent displacement, and the inclined inner wall design uses gravity to automatically guide debris, avoiding accumulation at the edge of the collection box 34 and simplifying the manual cleaning process.

[0030] A load-bearing block is fixedly connected to the machine tool body 1, and a servo motor 35 is fixedly connected to the load-bearing block. A mounting block is fixedly connected to the top of the machine tool body 1, and the threaded rod 36 is rotatably connected to the mounting block on the side away from the servo motor 35.

[0031] The load-bearing block ensures the operational stability of the servo motor 35, and the mounting block supports the far end of the threaded rod 36, reducing rotational runout and extending the service life of the threaded rod 36 and the threaded cylinder 37.

[0032] A limit groove is provided on the top of the machine tool body 1, and the size of the limit groove is adapted to the movement trajectory of the limit block 38.

[0033] The trajectory of the limiting groove and the limiting block 38 are matched, constraining the threaded cylinder 37 to move only in a straight line, preventing the cleaning component 3 from shifting, and ensuring the precise alignment of the cleaning brush 33 with the groove of the worktable 2.

[0034] By energizing the electromagnet 31, the servo motor 35 is activated, driving the threaded rod 36 to rotate forward. Under the restriction of the limit block 38, the threaded cylinder 37 drives the electromagnet 31, the connecting plate 32, and the cleaning brush 33 to move towards the collection frame 34. The cleaning brush 33 sweeps the debris in the groove of the worktable 2 into the collection frame 34, and the electromagnet 31 attracts the metal-containing debris to the bottom of the connecting plate 32. When the cleaning brush 33 moves above the collection frame 34, the servo motor 35 is turned off, and the electromagnet 31 is de-energized, so that the metal debris can be poured into the collection frame 34, completing the automatic cleaning of CNC machine tool milling debris.

[0035] Example 2

[0036] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Furthermore, based on Embodiment 1, the cleaning component 3 is provided with a quick-release component 4;

[0037] The quick-release assembly 4 includes a connector 41, and a connecting rod 42 is movably connected inside the connector 41.

[0038] The connecting seat 41 is fixedly connected to the electromagnet 31. The connecting seat 41 has an internal thread, and the connecting rod 42 has an external thread that matches the internal thread.

[0039] The threaded connector 41 and the connecting rod 42 can be quickly disassembled by screwing, which facilitates the quick disassembly and assembly of the sweeping brush 33, makes it easy to clean the sweeping brush 33, prevents debris accumulation, and improves the ease of operation.

[0040] With the above technical solution, when the cleaning brush 33 is moved above the collection frame 34, the connecting plate 32 is rotated until the connecting seat 41 and the connecting rod 42 are disengaged. The cleaning brush 33 can then be removed for cleaning to prevent debris from accumulating in the cleaning brush 33 for a long time, which would affect the cleaning effect of milling debris.

[0041] In actual operation, when this device is in use, the servo motor 35 is first started to drive the threaded rod 36 to rotate. With the cooperation of the limit block 38 and the limit groove, the threaded cylinder 37 drives the electromagnet 31, the connecting plate 32 and the cleaning brush 33 to move linearly along the groove of the worktable 2. The energized electromagnet 31 attracts iron filings through the metal connecting plate 32. At the same time, the cleaning brush 33 sweeps all the debris in the groove towards the collection frame 34. When the cleaning component 3 moves above the collection frame 34, the servo motor 35 stops and the electromagnet 31 is de-energized. The iron filings fall off under the action of gravity and fall into the collection frame 34 with ordinary debris on the inclined inner wall. If maintenance is required, the quick-release component 4 can be rotated to separate the connecting seat 41 from the connecting rod 42, and the cleaning brush 33 can be disassembled for cleaning. After completion, tightening it again will restore the automatic cleaning function.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
