Description

Technical Field

[0001] This utility model relates to the field of dust removal technology for milling machines, and in particular to a CNC gantry milling machine with a dust collection function. Background Technology

[0002] The existing gantry milling machine has its guide rails positioned at a low position close to the work platform, making it susceptible to dust pollution. This is especially true during the processing of ceramic and graphite workpieces, which generates a large amount of dust, necessitating the installation of various dust removal devices.

[0003] In the existing technology, the workpiece is usually placed in a closed space and equipped with a vacuum cleaner during reprocessing. However, the friction generated by the milling head when drilling the ceramic workpiece causes charge separation, which makes the dust particles static. The static dust is easy to be attracted to the ceramic workpiece. Therefore, the existing dust removal methods are difficult to remove the dust adsorbed on the ceramic surface, thus affecting the milling head's processing of the ceramic workpiece.

[0004] Meanwhile, in existing technologies, the removal of dust inside holes usually involves installing air pipes on both sides of the drill bit and blowing the dust out of the hole by oblique air blowing. This blowing method is ineffective and makes it difficult to blow out the dust from deep holes. Utility Model Content

[0005] To overcome the problem of removing dust from holes, air pipes are usually installed on both sides of the cutter head. The dust in the hole is blown out by blowing at an angle through the air pipes. However, this blowing method is ineffective and has the disadvantage of being difficult to blow out the dust in deep holes. This utility model provides a CNC gantry milling machine with a dust collection function.

[0006] The technical solution is as follows: A CNC gantry milling machine with a dust extraction function includes a worktable, a gantry frame, a moving part, a base, and a motor; the gantry frame is located behind the worktable; the moving part is installed on the upper front side of the gantry frame; the base is fixedly connected to the front side of the moving part; the motor is fixedly connected to the base; it also includes a fixed column, an air inlet pipe, a fixed sleeve, a milling head, a retaining ring, a connecting pipe, and a sealing ring; the fixed column is fixedly connected to the lower part of the base, the output shaft of the motor passes through the fixed column, and the fixed column is hollow inside; a cavity is provided in the upper part of the fixed column; several through slots are opened in the cavity; a fixed sleeve is rotatably connected to the middle of the fixed column, and the fixed sleeve is fixedly connected to the output shaft of the motor; a milling head is snapped onto the fixed sleeve; several through holes for air to pass through are opened on the milling head; a retaining ring is slidably connected to the upper part of the fixed column; several connecting pipes are fixedly connected to the retaining ring; a sealing ring is fixedly connected to the middle of the fixed sleeve, the sealing ring is an air bladder, and the sealing ring is connected to one end of the connecting pipe.

[0007] Furthermore, it also includes cylinders, spring columns, fixing plates, circular covers, connecting plates, telescopic tubes, and circular tubes; several cylinders are fixedly connected to the lower side of the base; each cylinder's telescopic part is fixedly connected to a spring column; all spring columns are fixedly connected to a fixing plate; a circular cover is fixedly connected to the middle of the fixing plate, and the interior of the circular cover is hollow; a connecting plate is provided on the outer ring surface of the circular cover; several sets of slots are opened on the inner ring surface of the circular cover, and each set consists of three slots; a telescopic tube is provided on the lower left side of the fixing column; a circular tube is installed on the upper side of the telescopic tube, and the interior of the circular tube is hollow; a sealing part is provided on the inner ring surface of the circular tube, and the sealing part is an airbag.

[0008] Furthermore, the slots in each group are arranged in a staggered manner.

[0009] Furthermore, it also includes connecting rods, elastic elements, and scraper rings; several connecting rods are slidably connected to the circular tube, and the fixing sleeve cooperates with the connecting rods; several elastic elements are fixedly connected to the lower side of the circular tube, and the elastic elements are located on the outer ring surface of the connecting rods; a scraper ring is fixedly connected to the lower side of all the connecting rods, and one end of the elastic element is fixedly connected to the scraper ring.

[0010] Furthermore, the upper surface of the scraper ring is set as an inclined surface.

[0011] The beneficial effects of this utility model are:

[0012] When replacing the milling head later, the gap between the upper end of the milling head and the fixed sleeve will also be different for milling heads of different sizes. Therefore, the gaps of different sizes can be sealed by expanding the sealing ring, thereby improving the practical performance of the sealing ring.

[0013] Under the action of the round cover, round tube and the expanded sealing part, the area where the milling head processes the ceramic workpiece will be in a closed state. This avoids the large amount of dust generated during the reprocessing of the ceramic workpiece from flying everywhere, which would cause the dust to adhere to the surface of the ceramic workpiece and affect the processing. Also, the dust may enter the guide rail, lead screw and other moving parts, which would lead to increased wear and thus affect the accuracy of the milling machine.

[0014] Because the air contains a large number of positive and negative ions under the action of the ion fan, the positive and negative ions neutralize the charge of the dust, thus avoiding the charge separation caused by the friction generated when the milling head drills the ceramic workpiece. This prevents the dust particles from becoming statically charged, and the statically charged dust is easily adsorbed on the ceramic surface and the inner wall of the round shell, making it difficult to remove the dust.

[0015] Air will be blown downwards through the through hole, and the blown-out air will remove the dust adhering to the milling head, thus avoiding the generation of static electricity when the milling head rotates at high speed during the processing of ceramic workpieces. In addition, ceramic dust itself is easy to be charged, and the electrostatic attraction between the two will cause the dust to adhere to the milling head. If the dust is not treated, it will affect the processing quality of the milling head on ceramic workpieces or cause the wear of the milling head to be accelerated.

[0016] At the same time, the gas blown out through the through hole will also enter the hole along the threaded groove on the milling head, thereby blowing away the dust inside the hole and preventing a small amount of dust from adhering to the inner wall of the hole, which would cause wear to the milling head during processing and shorten the service life of the milling head.

[0017] Thus, by setting the above-mentioned through holes, the gas can be blown straight down, ensuring that all the dust in the hole can be blown out. This solves the problem in the prior art, where air pipes are usually installed on both sides of the cutter head and the dust in the hole is blown out by the oblique blowing method of the air pipes. This blowing method is ineffective and difficult to blow out the dust in deep holes. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] It also includes cylinders 13, spring pillars 14, fixing plates 15, circular covers 16, connecting plates 17, telescopic tubes 18, and circular tubes 19; two cylinders 13 are bolted to the lower side of the base 4 and are symmetrically distributed on the left and right; each cylinder 13 has a spring pillar 14 fixedly connected to its telescopic part; all spring pillars 14 are fixedly connected to the fixing plate 15; the circular cover 16 is fixedly connected to the middle of the fixing plate 15, and the interior of the circular cover 16 is hollow to allow air to pass through; the upper part of the outer ring surface of the circular cover 16 is fixedly connected to and connected to the connecting plate 17; the inner ring surface of the circular cover 16 has three sets of slots 161 distributed vertically, and each set consists of three slots 161; the lower left side of the fixing pillar 6 is fixedly connected to and connected to the telescopic tube 18; the upper side of the telescopic tube 18 is equipped with a circular tube 19, and the interior of the circular tube 19 is hollow to allow air to pass through; the inner ring surface of the circular tube 19 is provided with a sealing part 191, and the sealing part 191 is an airbag.

[0029] The slots 161 are staggered, allowing dust to be sucked up from all directions.

[0030] It also includes connecting rods 20, elastic elements 21, and scraper rings 22; two connecting rods 20 are slidably connected to the circular tube 19, and the fixing sleeve 8 cooperates with the connecting rods 20; two elastic elements 21 are fixedly connected to the lower inner side of the circular tube 19, and the elastic elements 21 are located on the outer ring surface of the connecting rods 20; all the connecting rods 20 are fixedly connected to the lower side of the scraper rings 22, and one end of the elastic element 21 is fixedly connected to the scraper rings 22.

[0031] The upper surface of the scraper ring 22 is set as an inclined surface to prevent the scraper ring 22 from accumulating on the upper surface of the scraper ring 22 when scraping the dust adhering to the inner wall of the circular cover 16.

[0032] When using this CNC gantry milling machine with dust extraction function, firstly, the air inlet pipe 7 and the connecting plate 17 are connected to the external ion fan. Next, the operator places the ceramic workpiece to be processed on the worktable 1 and fixes it. Then, the control moving part 3 drives the base 4 to move to the left, and the motor 5 and its connected parts will move synchronously with the base 4. Then, the control moving part 3 drives the base 4 to move down, and the motor 5 and its connected parts will move synchronously with the base 4. During this process, the external ion fan is simultaneously controlled to deliver air to the cavity 61 through the air inlet pipe 7. The air then enters the sealed cavity through the connecting pipe 11. Inside the sealing ring 12, since the sealing ring 12 is set as an airbag, air will force the sealing ring 12 to expand, so that the sealing ring 12 seals the gap between the fixed sleeve 8 and the milling head 9, thereby enhancing the sealing between the fixed sleeve 8 and the milling head 9, thus preventing subsequent air leakage through the gap between the fixed sleeve 8 and the milling head 9. It should be noted that when the milling head 9 is replaced later, for milling heads 9 of different sizes, the gap between the upper end of the milling head 9 and the fixed sleeve 8 will also be different. Therefore, the expansion of the sealing ring 12 can seal the gap of different sizes, thereby improving the practical performance of the sealing ring 12.

[0033] Meanwhile, some air in the cavity 61 will enter the fixed column 6 through the through groove 62, and then the air will enter the round tube 19 through the telescopic tube 18. Since the sealing part 191 is set as an airbag, the air will force the sealing part 191 to expand, so that the expanded sealing part 191 contacts the milling head 9. As the base 4 moves down, when the milling head 9 contacts the upper surface of the ceramic workpiece, the control cylinder 13 causes the spring column 14 to move down. The fixed plate 15, the round cover 16, the connecting plate 17, the telescopic tube 18, the round tube 19, the connecting rod 20, the elastic element 21 and the scraper ring 22 move synchronously with the spring column 14. The telescopic tube 18 is stretched, and then the round cover... The lower surface of the shell 16 will contact the ceramic workpiece. Then, the control motor 5 drives the fixed sleeve 8 to rotate. The milling head 9, the retaining ring 10, and the connecting pipe 11 will rotate synchronously with the fixed sleeve 8. Then, the milling head 9 will drill holes in the ceramic workpiece. During this process, under the action of the round shell 16, the round pipe 19, and the expanded sealing part 191, the area where the milling head 9 processes the ceramic workpiece will be in a closed state. This avoids the large amount of dust generated during the reprocessing of the ceramic workpiece from flying everywhere, which would cause the dust to adhere to the surface of the ceramic workpiece and affect the processing. Also, the dust may enter the guide rail, lead screw, and other moving parts, causing increased wear and thus affecting the accuracy of the milling machine.

[0034] During the ceramic workpiece processing, the external ion fan is simultaneously controlled to generate negative pressure inside the circular cover 16 through the connecting plate 17, so that the slot 161 forms a suction force. During this process, due to the action of the ion fan, the air contains a large number of positive and negative ions, which neutralize the dust charge through positive and negative ions. This avoids the friction generated when the milling head 9 drills the ceramic workpiece, which would cause charge separation and make the dust particles static. The static dust is easily adsorbed on the ceramic surface and the inner wall of the circular cover 16, making it difficult to remove the dust. The dust generated during the ceramic workpiece processing will be removed through the slot 161, and the removed dust will pass through the circular cover 16 and the connecting plate 17 in sequence, and then be collected and processed.

[0035] Meanwhile, after the air enters the fixed column 6, some air will also enter the fixed sleeve 8. As the air pressure inside the fixed column 6 and the fixed sleeve 8 increases, the air will be blown downwards through the through hole 91. The blown-out air will remove the dust adhering to the milling head 9, thus preventing the generation of static electricity when the milling head 9 rotates at high speed during the processing of ceramic workpieces. Since ceramic dust is easily charged, the electrostatic attraction between the two will cause the dust to adhere to the milling head 9. If the dust is not treated, it will affect the processing quality of the ceramic workpiece by the milling head 9, or lead to accelerated wear of the milling head 9. At the same time, the through hole... The gas blown out by 91 will also enter the hole along the threaded groove on the milling head 9, thereby achieving the effect of blowing away the dust in the hole and preventing a small amount of dust from adhering to the inner wall of the hole, causing wear to the milling head 9 during processing and shortening the service life of the milling head 9. Thus, through the setting of the above-mentioned through hole 91, the gas can be blown straight down, ensuring that all the dust in the hole can be blown away, thereby solving the problem in the prior art, which usually installs air pipes on both sides of the cutter head and blows the dust in the hole during drilling by oblique blowing through the air pipes. This blowing method is ineffective and difficult to blow out the dust in deep holes.

[0036] During the drilling of the ceramic workpiece by the milling head 9, as the base 4 and its connected parts continue to move downwards, the ceramic workpiece limits the movement of the circular cover 16. Therefore, the fixing plate 15, the circular cover 16, the connecting plate 17, the telescopic tube 18, the circular tube 19, the connecting rod 20, the elastic element 21, and the scraper ring 22 will not move. Consequently, the telescopic tube 18 will be further compressed, the spring column 14 will be compressed, and then the fixing sleeve 8 will push the connecting rod 20 downwards, the elastic element 21 will be stretched, and the scraper ring 22 will move synchronously with the connecting rod 20. Consequently, the scraper ring 22 will press against the inner wall of the circular cover 16. The dust on the surface is scraped off to prevent excessive dust from adhering to the round cover 16 over a long period of time. The adhering dust may fall into the processing area due to the vibration of the equipment, causing contamination of the ceramic workpiece surface. It should be noted that when the scraper ring 22 is reset from bottom to top, the scraper ring 22 can further process the inner wall of the round cover 16. During this process, since the upper surface of the scraper ring 22 is set as a slope, when the scraped dust falls onto the scraper ring 22, the dust will roll off along the slope of the scraper ring 22, thereby preventing the scraped dust from accumulating on the upper surface of the scraper ring 22.

[0037] It should be noted that when the milling head 9 needs to be replaced later, the operator can control the cylinder 13 to move the spring column 14 upward, so that more of the lower end of the milling head 9 is exposed from the round cover 16, making it easier for the operator to hold the milling head 9. In this way, the milling head 9 can be disassembled and installed more conveniently.

[0038] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model.
