Description

Technical Field

[0001] This invention belongs to the field of CNC machining technology, specifically a multi-axis machining center and its usage method. Background Technology

[0002] A multi-axis machining center is a highly integrated and automated machining equipment. It controls multiple high-precision servo motors through a control system to drive multiple machining tools to perform precise machining operations in different directions.

[0003] However, a large amount of chips are generated during the machining process of multi-axis machining centers. These chips splash into the surrounding environment, which not only poses a safety hazard to operators, but also easily adheres to the workpiece or cutting tool, leading to a decrease in machining accuracy. Therefore, it is necessary to deal with the chips in a timely manner. Currently, most machining centers rely on hand tools to sweep and clean the iron filings that splash and accumulate on the machine table. This is not only inefficient, but also requires operators to stop frequently to clean, which also affects the machining efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-axis machining center and its usage method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-axis machining center, including a machining table, a gantry frame mounted on the top of the machining table, a dust collection assembly disposed below the gantry frame, and a mounting bracket fixedly mounted on the side wall of the gantry frame;

[0006] The dust collection assembly includes a first dust collection pipe disposed below the gantry frame. Second dust collection pipes are evenly installed on the outer wall of the first dust collection pipe. An installation block is fixedly installed on the outer wall of the first dust collection pipe. The installation block is rotatably installed at the bottom of the gantry frame via a rotating assembly. A corrugated pipe is fixedly connected to one end of the first dust collection pipe. A connecting pipe is fixedly installed at the top end of the corrugated pipe. The connecting pipe is disposed inside the gantry frame. A processing chamber is opened inside the processing chamber. A dust collection pump is disposed on one side of the processing chamber. A filter screen is installed inside the processing chamber.

[0007] As a further technical solution of the present invention, a magnetic plate is fixedly installed on the inner wall of the processing chamber, and a scraping component is provided on one side of the magnetic plate. Since not only chips but also cutting fluid are generated during the processing, when the dust pump is started during the processing, the chips and cutting fluid will enter the processing chamber together. The magnetic plate can adsorb the chips of ferromagnetic materials, separate the chips and cutting fluid, and facilitate subsequent processing.

[0008] As a further technical solution of the present invention, the filter screen is provided with multiple screens.

[0009] As a further technical solution of the present invention, the scraping assembly includes a scraper disposed on one side of the magnetic plate, the inner wall of the scraper is threadedly connected to a threaded rod, the threaded rod is rotatably installed inside the gantry frame, and a motor is installed at the bottom end of the threaded rod.

[0010] As a further technical solution of the present invention, a baffle is provided at the bottom end of the magnetic plate, and the baffle is rotatably installed inside the gantry frame via a first rotating shaft.

[0011] As a further technical solution of the present invention, a torsion spring is installed on the outer wall of the first rotating shaft.

[0012] As a further technical solution of the present invention, a collection box is provided below the magnetic plate, and the collection box is slidably installed inside the gantry frame.

[0013] As a further technical solution of the present invention, a partition is fixedly installed on the inner wall of the collection box.

[0014] As a further technical solution of the present invention, the rotating assembly includes a worm gear installed inside the gantry frame, a second rotating shaft is fixedly connected to the inner wall of the worm gear, the second rotating shaft is embedded inside the mounting block, a worm is meshed with one side of the worm gear, a rotating block is fixedly connected to the top end of the worm, and the rotating block is set at the top end of the gantry frame.

[0015] A method for using a multi-axis machining center includes the following steps:

[0016] S1: When working in a multi-axis machining center, first adjust the suction angle of the second suction pipe according to the machining requirements. By rotating the rotating block, the worm gear is driven to rotate. The rotation of the worm gear drives the rotation of the worm wheel. The rotation of the worm wheel drives the rotation of the second rotating shaft. The rotation of the second rotating shaft drives the rotation of the mounting block. The rotation of the mounting block drives the rotation of the first suction pipe. The rotation of the first suction pipe drives the rotation of the second suction pipe, so as to adjust the suction angle.

[0017] S2: During the processing, the dust pump and motor are started simultaneously to create a negative pressure in the processing chamber. The chips generated during the processing are sucked into the processing chamber through the second dust suction pipe. The metal chips in the chips are attracted to the surface by the magnetic plate. When the motor starts, the threaded rod rotates. The rotation of the threaded rod drives the scraper to move back and forth. When the scraper contacts the baffle, it forces the baffle to rotate downward around the first rotation axis, exposing the collection box. The scraper can scrape the metal chips on the surface of the magnetic plate into the collection box for collection.

[0018] S3: When the baffle rotates, the torsion spring deforms and stores elastic potential energy. When the scraper moves up, the elastic potential energy is released through the torsion spring to reset the baffle and close the collection box. After processing is completed, the collection box is removed for maintenance.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. By setting up a dust collection component, the present invention activates the dust collection pump when the multi-axis machining center is working, creating a negative pressure in the processing chamber. The chips generated during the processing are then sucked away through the second dust collection pipe, which not only improves the safety of the processing but also ensures the processing accuracy.

[0021] 2. By setting up a scraping component, the present invention enables the motor to be started when the multi-axis machining center is working. The start of the motor drives the rotation of the threaded rod, and the rotation of the threaded rod drives the scraper to move back and forth, scraping the chips adsorbed on the side wall of the magnetic plate to the bottom, thus preventing the excessive metal chips adhering to the surface of the magnetic plate after a period of use, which would affect the adsorption effect of the magnetic plate.

[0022] 3. By configuring the rotating assembly, this invention allows for adjustment of the suction angle of the second suction pipe during operation in a multi-axis machining center. Rotating the rotating block drives the rotation of the worm gear, which in turn drives the rotation of the worm wheel. The worm wheel's rotation drives the rotation of the second rotating shaft, which in turn drives the rotation of the mounting block. The mounting block's rotation then drives the rotation of the first suction pipe, which in turn drives the rotation of the second suction pipe. Adjusting the suction angle of the second suction pipe ensures it more effectively targets the dust generated during cutting, improving suction efficiency and thus enhancing the working environment of the multi-axis machining center.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 7 As shown in the embodiment of the present invention, a multi-axis machining center includes a machining table 1, a gantry frame 2 is mounted on the top of the machining table 1, a dust collection component is provided below the gantry frame 2, and a mounting bracket 3 is fixedly mounted on the side wall of the gantry frame 2.

[0033] The dust collection assembly includes a first dust collection pipe 9 located below the gantry frame 2. Second dust collection pipes 25 are evenly installed on the outer wall of the first dust collection pipe 9. An installation block 10 is fixedly installed on the outer wall of the first dust collection pipe 9. The installation block 10 is rotatably installed at the bottom of the gantry frame 2 via a rotating assembly. A corrugated pipe 8 is fixedly connected to one end of the first dust collection pipe 9. A connecting pipe 7 is fixedly installed at the top end of the corrugated pipe 8. The connecting pipe 7 is located inside the gantry frame 2. A processing chamber 5 is opened inside the gantry frame 2. A dust collection pump 6 is provided on one side of the processing chamber 5. A filter screen 12 is installed inside the processing chamber 5.

[0034] By setting up the dust collection component, when the multi-axis machining center is working, the dust collection pump 6 is started to create a negative pressure in the processing chamber 5, and the chips generated during the processing are sucked away through the second dust collection pipe 25, which not only improves the safety of processing, but also ensures processing efficiency.

[0035] like Figure 2 and Figure 3 As shown, a magnetic plate 11 is fixedly installed on the inner wall of the processing chamber 5, and a scraping component is provided on one side of the magnetic plate 11.

[0036] Since not only chips but also cutting fluid are generated during the processing, when the dust pump 6 is started during the processing, the chips and cutting fluid will enter the processing chamber 5 together. The magnetic plate 11 can adsorb the ferromagnetic material chips, separating the chips and cutting fluid for subsequent processing.

[0037] like Figure 2 and Figure 3 As shown, multiple filters 12 are provided.

[0038] During the machining process, metal shavings, particles, suspended solids and other contaminants will be mixed into the cutting fluid. These contaminants will reduce the cleanliness and stability of the cutting fluid. By filtering through multiple filters 12, these impurities and particles can be removed, making it easier to separate the cutting fluid from the impurities and to recycle the cutting fluid.

[0039] like Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the scraping assembly includes a scraper 18 disposed on one side of the magnetic plate 11. A threaded rod 19 is threadedly connected to the inner wall of the scraper 18. The threaded rod 19 is rotatably installed inside the gantry frame 2. A motor 20 is installed at the bottom end of the threaded rod 19.

[0040] One side of the scraper 18 slides against the side wall of the magnetic plate 11;

[0041] By setting up the scraping component, when working in a multi-axis machining center, the motor 20 is started. The start of the motor 20 drives the rotation of the threaded rod 19. The rotation of the threaded rod 19 drives the scraper 18 to move back and forth, scraping the chips adsorbed on the side wall of the magnetic plate 11 to the bottom, preventing the magnetic plate 11 from having too many metal chips adhering to its surface after a period of use, which would affect the adsorption effect of the magnetic plate 11.

[0042] like Figure 2 , Figure 3 and Figure 4 As shown, a baffle 15 is provided at the bottom of the magnetic plate 11, and the baffle 15 is rotatably installed inside the gantry frame 2 via the first rotating shaft 16.

[0043] As the scraper 18 moves downward, it contacts the baffle 15, forcing the baffle 15 to rotate downward around the first rotation axis 16, exposing the collection box 13. The scraper 18 can then scrape off the metal shavings from the surface of the magnetic plate 11.

[0044] like Figure 6 As shown, a torsion spring 17 is installed on the outer wall of the first rotating shaft 16.

[0045] When the baffle 15 rotates, the torsion spring 17 deforms and stores elastic potential energy. When the scraper 18 moves upward, the elastic potential energy is released through the torsion spring 17 to reset the baffle 15 and close the collection box 13.

[0046] like Figures 1 to 5 As shown, a collection box 13 is provided below the magnetic plate 11, and the collection box 13 is slidably installed inside the gantry frame 2.

[0047] Collect the scraped metal shavings for later unified processing.

[0048] like Figure 3 As shown, a partition 14 is fixedly installed on the inner wall of the collection box 13.

[0049] The collection box 13 is divided into two chambers by the partition 14. The two chambers are located below the magnetic plate 11 and the filter screen 12, respectively, for the separate collection of metal shavings and cutting fluid.

[0050] like Figure 4 and Figure 5 As shown, the rotating assembly includes a worm gear 22 installed inside the gantry frame 2. A second rotating shaft 23 is fixedly connected to the inner wall of the worm gear 22. The second rotating shaft 23 is embedded inside the mounting block 10. A worm 21 is meshed with one side of the worm gear 22. A rotating block 24 is fixedly connected to the top of the worm 21. The rotating block 24 is located at the top of the gantry frame 2.

[0051] By adjusting the suction angle of the second suction pipe 25 during operation of the multi-axis machining center through the rotation component, the rotation of the rotating block 24 drives the rotation of the worm gear 21, which in turn drives the rotation of the worm wheel 22. The rotation of the worm wheel 22 drives the rotation of the second rotating shaft 23, which in turn drives the rotation of the mounting block 10. The rotation of the mounting block 10 drives the rotation of the first suction pipe 9, which in turn drives the rotation of the second suction pipe 25. Adjusting the suction angle of the second suction pipe 25 ensures that it more effectively targets the dust generated during the cutting process, improving suction efficiency and thus improving the working environment of the multi-axis machining center.

[0052] A method for using a multi-axis machining center includes the following steps:

[0053] Working principle and usage process:

[0054] S1: When working in a multi-axis machining center, first adjust the suction angle of the second suction pipe 25 according to the processing requirements. By rotating the rotating block 24, the worm 21 is driven to rotate. The rotation of the worm 21 drives the rotation of the worm wheel 22. The rotation of the worm wheel 22 drives the rotation of the second rotating shaft 23. The rotation of the second rotating shaft 23 drives the rotation of the mounting block 10. The rotation of the mounting block 10 drives the rotation of the first suction pipe 9. The rotation of the first suction pipe 9 drives the rotation of the second suction pipe 25 to adjust the suction angle.

[0055] S2: During the processing, the dust pump 6 and motor 20 are started simultaneously to create a negative pressure in the processing chamber 5. The chips generated during the processing are sucked into the processing chamber 5 through the second dust suction pipe 25. The metal chips in the chips are attracted to the surface by the magnetic plate 11. When the motor 20 is started, the threaded rod 19 rotates. The rotation of the threaded rod 19 drives the scraper 18 to move back and forth. When the scraper 18 contacts the baffle 15, it forces the baffle 15 to rotate downward around the first rotating shaft 16, exposing the collection box 13. The scraper 18 can scrape the metal chips on the surface of the magnetic plate 11 into the collection box 13 for collection.

[0056] S3: When the baffle 15 rotates, the torsion spring 17 deforms and stores elastic potential energy. When the scraper 18 moves up, the elastic potential energy is released through the torsion spring 17 to reset the baffle 15 and close the collection box 13. After processing is completed, the collection box 13 is taken out for maintenance.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
