Description

Technical Field

[0001] The utility model relates to the technical field of milling machine cleaning, in particular to a milling machine cleaning device for CNC processing. Background Art

[0002] CNC milling machine, also known as CNC machining center, is a machine-operated cutting tool programmed and managed by a computer digital control system. The cleaning device for CNC milling machine is an important equipment to keep the milling machine clean and extend its service life. It can effectively remove impurities such as iron filings, oil stains and dust generated by the milling machine during the machining process to ensure that the milling machine remains clean. The cleaning device for CNC milling machine usually cleans several key components such as nozzles, brush plates and brushes, drive systems, and control systems.

[0003] When the existing brush plate is in use, the brush will be worn out as the brush is repeatedly cleaned. If there is a gap between the brush and the milling cutter table, the brush cannot clean the milling cutter table when it moves.

[0004] The existing public technical solution, with announcement number CN212858741U, discloses a cleaning structure for a milling machine workbench. By arranging a threaded rod on the top of the brush, the rotation of the threaded rod can drive the two sets of connecting plates to move downward, thereby making up for the gap between the scraper and the brush caused by wear, ensuring that the bottom of the scraper and the bottom of the brush are in contact with the surface of the workbench body, thereby ensuring the cleaning effect of the workbench.

[0005] When in use, cooperate with the collection box at the bottom to sweep the waste slag on the workbench into the collection box with a brush. The waste slag will contain iron filings, and the iron filings inside the collection box need to be collected to meet the recycling of iron filings. If a stationary magnet is directly placed in the collection box, the magnet will not be able to completely collect all the iron filings in the collection box. Summary of the invention

[0006] The purpose of the utility model is to provide a cleaning device for a milling machine used for CNC processing, which can use a moving magnet to thoroughly clean the iron filings in a waste liquid storage box to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a CNC milling machine cleaning device, comprising a CNC machining center, a milling machine body is arranged inside the CNC machining center, a movable brush plate is arranged above the milling machine body, a waste liquid storage box is arranged below the milling machine body, a waste liquid mixing mechanism is arranged inside the waste liquid storage box, and iron scrap adsorption mechanisms are installed on both the front and rear sides of the waste liquid mixing mechanism;

[0008] The iron chip adsorption mechanism includes a first screw rod installed inside the waste liquid storage box, and a second screw rod is arranged on one side of the first screw rod, screw rod sleeves are installed on the surfaces of the second screw rod and the first screw rod, and a magnet is fixed on the outside of the screw rod sleeve, and a screw rod bearing is installed at the connection between the second screw rod, the first screw rod and the waste liquid storage box.

[0009] Preferably, a guide slide rod is passed through the interior of the magnet, and both ends of the guide slide rod are fixed on the inner wall of the waste liquid storage box.

[0010] Preferably, the iron chip adsorption mechanism further includes a second driven gear installed at the power input end of the second screw rod, and a first driven gear installed at the power input end of the first screw rod.

[0011] Preferably, the waste liquid mixing mechanism comprises a driving gear sandwiched between a first driven gear and a second driven gear, and the first driven gear, the driving gear and the second driven gear are meshed and connected in sequence.

[0012] Preferably, the waste liquid mixing mechanism further comprises a mixing shaft installed in the middle of the driving gear, and mixing rods are arranged around the mixing shaft.

[0013] Preferably, a limit bearing is installed at the connection between the mixing rod and the waste liquid storage box, and the length of the waste liquid storage box is greater than the length of the milling machine body.

[0014] Preferably, the top of the movable brush plate is threadedly connected to a threaded rod, and the bottom end of the threaded rod is connected to a lifting plate via a bearing, and a brush is connected below the lifting plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The iron filings adsorption mechanism can use the moving magnet to thoroughly clean the iron filings in the waste liquid storage box. Since the magnet can move under the action of the screw rod, the iron filings can be collected more thoroughly;

[0017] 2. The waste liquid mixing mechanism can stir the waste liquid in the waste liquid storage box, so that the waste liquid in the waste liquid storage box can flow around, and the iron filings in the waste liquid can be moved, which makes it more convenient for the magnet to collect the iron filings. The waste liquid mixing mechanism and the iron filings adsorption mechanism can work synchronously through gears, thereby meeting the needs of thorough collection of iron filings.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4A milling machine cleaning device for CNC processing includes a CNC machining center 1, a milling machine body 2 is arranged inside the CNC machining center 1, and a movable brush plate 4 is arranged above the milling machine body 2, a threaded rod 7 is threadedly connected to the top of the movable brush plate 4, and a lifting plate 8 is connected to the bottom of the threaded rod 7 through a bearing, and a brush 9 is connected below the lifting plate 8, a waste liquid storage box 3 is arranged below the milling machine body 2, and a waste liquid mixing mechanism 5 is arranged inside the waste liquid storage box 3, and iron filings adsorption mechanisms 6 are installed on both the front and rear sides of the waste liquid mixing mechanism 5;

[0028] The iron chip adsorption mechanism 6 includes a first screw rod 604 installed inside the waste liquid storage box 3, and a second screw rod 606 is arranged on one side of the first screw rod 604, screw rod sleeves 605 are installed on the surfaces of the second screw rod 606 and the first screw rod 604, and a magnet 602 is fixed to the outside of the screw rod sleeve 605, and a screw rod bearing 603 is installed at the connection between the second screw rod 606 and the first screw rod 604 and the waste liquid storage box 3, a guide slide rod 601 is passed through the interior of the magnet 602, and both ends of the guide slide rod 601 are fixed on the inner wall of the waste liquid storage box 3, the iron chip adsorption mechanism 6 also includes a second driven gear 608 installed at the power input end of the second screw rod 606, and a first driven gear 607 installed at the power input end of the first screw rod 604.

[0029] By adopting the above technical solution, when the movable brush plate 4 moves above the milling machine body 2 through the linear guide rail, the upper end surface of the milling machine body 2 can be cleaned by the brush 9. Since the size of the waste liquid storage box 3 is larger than the size of the milling machine body 2, the cutting fluid, waste slag, stains and iron filings remaining on the milling machine body 2 will be swept into the waste liquid storage box 3 during cleaning. Then, the first screw rod 604 and the second screw rod 606 can be rotated, thereby driving the screw sleeve 605 on the first screw rod 604 and the second screw rod 606 to move axially on the surface of the first screw rod 604 and the second screw rod 606, and at this time, the magnet 602 can be driven to move synchronously. Since a guide slide bar 601 is provided on one side of the magnet 602, the magnet 602 can only move axially along the direction of the guide slide bar 601 and cannot rotate. When the magnet 602 approaches the iron filings while moving, it can adsorb the iron filings in the waste liquid storage box 3, thereby meeting the collection of the iron filings. When the height of the brush 9 needs to be adjusted, the threaded rod 7 is rotated, and a nut is provided between the threaded rod 7 and the movable brush plate 4. The nut is fixedly embedded in the interior of the movable brush plate 4. When the threaded rod 7 rotates, the lifting plate 8 can be pushed downward, thereby pushing the brush 9 to move toward the end face of the milling machine body 2, thereby reducing the gap between the milling machine body 2 and the brush 9.

[0030] Specifically, Figure 4As shown, preferably, the waste liquid mixing mechanism 5 includes a driving gear 504 sandwiched between a first driven gear 607 and a second driven gear 608, and the first driven gear 607, the driving gear 504 and the second driven gear 608 are meshed and connected in sequence, and the waste liquid mixing mechanism 5 also includes a mixing shaft 501 installed in the middle of the driving gear 504, and mixing rods 503 are arranged around the mixing shaft 501, and a limited bearing 502 is installed at the connection between the mixing rod 503 and the waste liquid storage box 3, and the length of the waste liquid storage box 3 is greater than the length of the milling machine body 2.

[0031] By adopting the above technical solution, a servo motor is installed on one side of the driving gear 504 and fixedly connected to the power output end of the servo motor. After the servo motor is started, the power output end of the servo motor drives the driving gear 504 to rotate, and drives the first driven gear 607 and the second driven gear 608 to rotate synchronously through the teeth. When the driving gear 504 rotates, the mixing shaft 501 can also be driven to rotate, so that the mixing rod 503 rotates inside the waste liquid storage box 3, and the waste liquid in the waste liquid storage box 3 flows around, so that the iron filings in the waste liquid are moved, which makes it more convenient for the magnet 602 to collect the iron filings. After the first driven gear 607 and the second driven gear 608 rotate synchronously, they simultaneously drive the first screw rod 604 and the second screw rod 606 to rotate, and cooperate with the moving magnet 602 to collect the iron filings.

[0032] Working principle: By starting the servo motor installed on the driving gear 504, the servo motor drives the driving gear 504 to rotate, and then the first driven gear 607 and the second driven gear 608 simultaneously drive the first screw rod 604 and the second screw rod 606 to rotate, and under the action of the screw rod sleeve 605, the magnet 602 is driven to move axially, and the rotating driving gear 504 drives the mixing shaft 501 to rotate, so that the mixing rod 503 rotates inside the waste liquid storage box 3, so that the waste liquid in the waste liquid storage box 3 flows around, which is convenient for the magnet 602 to absorb iron filings and quickly collect the iron filings.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
