Description

Technical Field

[0001] This utility model relates to the field of pneumatic cleaning technology, specifically a pneumatic cleaning device for a five-axis machining center. Background Technology

[0002] Five-axis machining centers are widely used in aerospace, mold manufacturing and other fields due to their multi-degree-of-freedom motion capabilities. The worktable is an important component of a five-axis machining center. Its main function is to fix the workpiece and ensure that the workpiece remains stable during the machining process, so as to avoid the workpiece from moving or vibrating and affecting the machining accuracy. During the machining process, chips, coolant and oil stains generated on the worktable and fixture surfaces are easy to accumulate. The worktable needs to be cleaned after each machining of the workpiece.

[0003] For example, a Chinese patent discloses a cleaning device for a machining center (publication number CN215700171U), which includes a base plate. Support rods are installed on both sides of the top of the base plate. A fixing plate is installed on the inner side of the support rods. A cleaning box is fixed on the inner side of the fixing plate. A partition is fixed inside the cleaning box. An air pump is installed on the top of the partition. A connecting pipe is connected to the top of the air pump. The other end of the connecting pipe is connected to an air gun.

[0004] However, the aforementioned publicly available documents possess advantages such as easy mobility, the ability to compress waste chips, and reduced frequency of emptying, solving the problems of existing machining center cleaning devices being inconvenient to move, having limited waste chip storage capacity, and requiring frequent emptying. However, when using this patent, the method of blowing away chips with an air gun makes it difficult to thoroughly clean the grooves on the worktable, resulting in significant cleaning difficulty. Incomplete cleaning can increase workpiece positioning errors and even damage precision molds. Therefore, those skilled in the art have provided a five-axis machining center pneumatic cleaning device to address the problems mentioned in the background art. Utility Model Content

[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] Please see Figures 1-6 In this embodiment of the utility model, a base 1 is included, a cleaning box 2 is fixed on the outer top surface of the base 1, a partition 201 is fixed inside the cleaning box 2, a storage battery 202 and an air pump 203 are fixedly installed on the outer top surface of the partition 201 respectively, the output end of the air pump 203 is fixed and connected to a guide pipe 204, a cleaning component 3 is provided at the air outlet end of the guide pipe 204, and a slag inlet 205 is opened on the rear outer wall of the cleaning box 2 below the partition 201.

[0023] Specifically, a rotatable cleaning door 9 is rotatably installed on the bottom of the left outer wall of the cleaning box 2, an rotatable maintenance door 10 is rotatably installed on the top of the front outer wall of the cleaning box 2, rollers 11 with braking function are symmetrically rotatably installed on the front and rear outer walls of the base 1, and a push handle 12 is fixed on the right outer wall of the cleaning box 2.

[0024] In this embodiment: When in use, hold the push handle 12 and move the device to the designated position using the rollers 11. Then, remove the cleaning component 3 from the slot on the top surface of the cleaning box 2. Control the air pump 203 to blow air into the cleaning component 3 along the air guide pipe 204 using the controller. (Adjust the pressure as needed using the pressure regulating valve installed on the air guide pipe 204 to avoid incomplete cleaning due to excessive or insufficient pressure.) The cleaning component 3 thoroughly cleans the workbench and the grooves on the workbench. During cleaning, ensure that the upper protective cover of the slag inlet 205 is aligned with the workbench to facilitate the entry of debris into the cleaning box 2. Once the cleaning box 2 is full, open the cleaning door 9 to clean the debris stored inside. The maintenance door 10 allows for the maintenance of the battery and air pump 203. (Battery 202 provides power to the air pump 203 and can be removed for easy replacement.)

[0025] Specifically, the cleaning component 3 includes a square block 301 disposed on the outer top surface of the cleaning box 2. A square cavity 302 is formed inside the square block 301, and a straight-blowing pipe 303 is rotatably mounted inside the square cavity 302. A through-hole is formed on the right outer wall of the square block 301, and a rotary joint 304 is fixed inside the mounting hole. One end of the straight-blowing pipe 303 extends rotatably onto the left outer wall of the square block 301, and oblique-blowing pipes 305 are fixed and connected to the upper and lower ends of its outer peripheral sidewall, respectively. The other end is rotatably connected to the rotary joint 304. A through-hole is formed at the center of the outer top surface of the square block 301. A square opening is formed, and a U-shaped sleeve 306 is fixedly installed on the outer top surface of the square block 301 at the opening. A rotating shaft 307 is rotatably installed inside the U-shaped sleeve 306. A gear 308 is fixedly installed at one end of the rotating shaft 307. An external gear ring 309 is fixed on the outer peripheral side wall of the straight blow pipe 303. The gear 308 and the external gear ring 309 are meshed and connected to each other. A drive motor 310 is fixedly installed on the right outer wall of the U-shaped sleeve 306. One end of the rotating shaft 307 extends rotatably to the rear outer wall of the U-shaped sleeve 306 and is fixedly connected to the output end of the drive motor 310. The air guide pipe 204 and the rotary joint 304 are fixed to each other and connected through each other.

[0026] In this embodiment: First, the square block 301 is pushed into the groove on the workbench. Then, the inside of the groove is cleaned by the straight blow pipe 303 and the oblique blow pipe 305. At the same time, the drive motor 310 is controlled and started to drive the rotating shaft 307 to rotate the gear 308 inside the loop sleeve 306. Under the meshing connection characteristics of the gear 308, the external gear ring 309 is driven to rotate the straight blow pipe 303 and the oblique blow pipe 305. The oblique blow pipe 305 blows air towards the inner wall of the groove, causing the chips adhering to the inner wall of the groove to be blown off. The straight blow pipe 303 blows the chips that were originally left in the groove and the chips blown off by the oblique blow pipe 305 directly out of the groove, so that the chips in the groove are quickly discharged. This achieves the effect of thoroughly cleaning the groove on the workbench and improves the applicability.

[0027] Specifically, a support plate 4 is fixedly installed on the outer top surface of the U-shaped sleeve 306. A through-type vertical groove 401 is opened on the outer wall of the support plate 4. A threaded rod 402 is rotatably installed inside the vertical groove 401. A U-shaped slider 403 is threaded onto the outer peripheral wall of the threaded rod 402. A straight block 404 is fixed to the left outer wall of the support plate 4 at both ends of the U-shaped slider 403. A through-type opening 405 is opened on the front outer wall of the straight block 404. Connecting blocks 5 are symmetrically slidably connected inside the opening 405. The opposite ends of the two connecting blocks 5 slide to the front and rear outer walls of the straight block 404 and are fixedly connected to cleaning blocks 501. A through-type sliding opening 502 is symmetrically opened on the outer top surface of the straight block 404. Each of the outer top surfaces of the connecting block 5 has a through-hole sliding opening 503. The inner sides of the two sliding openings 502 and the two sliding openings 503 are slidably inserted with sliding rods 504. The outer top surfaces of the two sliding rods 504 are fixed with connecting plates 505. The connecting plates 505 are threadedly fixed to the straight block 404 by positioning screws 506. One end of the threaded rod 402 extends to the outer top surface of the support plate 4, and a knob 6 is fixed on the outer peripheral side wall. A power box 7 is fixedly installed on the right outer wall of the support plate 4. The power box 7 contains a rechargeable battery 2 (which provides power to the drive motor 310). The power box 7 also has a USB charging port for charging the battery 2. A handle 8 is fixed on the right outer wall of the power box 7.

[0028] In this embodiment: When the square block 301 is placed into the groove of the workbench, the knob 6 is turned to drive the threaded rod 402 to move the U-shaped slider 403 up and down along the vertical groove 401, so that the straight block 404, carrying the cleaning block 501, fits against the outer surface of the workbench. (After they fit against each other, the threaded rod 402 is locked by the shaft locker on the top surface of the support plate 4 to prevent self-rotation.) Then, the handle 8 is used to push the support plate 4 to move the cleaning block 501 and the straight block 404, so that the cleaning block 501 can clean the debris on the workbench simultaneously. When the cleaning block 501 is to be replaced, first turn and remove the positioning screw 506, then move the connecting plate 505 to pull the slide bar 504 out from the inside of the slide opening 1 502 and slide opening 2 503, so that the cleaning block 501 can be removed for replacement. Conversely, it can be installed.

[0029] When using the device, first move it to the designated position, then align the upper protective cover of the slag inlet 205 with the worktable, and then hold the handle 8 to remove the square block 301 from the cleaning box 2 and place it into the groove on the worktable. Then, turning the knob 6 drives the threaded rod 402 to move the U-shaped slider 403 along the vertical groove 401, so that the straight block 404 with the cleaning block 501 fits against the outer surface of the workbench. The air pump 203 blows air along the air guide pipe 204 into the straight blowing pipe 303 and the oblique blowing pipe 305. The drive motor 310 is started to drive the rotating shaft 307 to rotate the gear 308, so that the external gear ring 309 drives the straight blowing pipe 303 and the oblique blowing pipe 305 to rotate. At the same time, the handle 8 is held to push the support plate 4 to push, so as to achieve the effect of cleaning the workbench and the groove simultaneously. The debris after cleaning enters the interior of the cleaning box 2 along the protective cover and the slag inlet 205 for storage, which is convenient for subsequent cleaning. (It should be noted that the control method in this utility model is controlled by a PLC controller. The control circuit of the PLC controller can be implemented by those skilled in the art through programming, and thus can operate normally according to the above steps. The power supply is also common knowledge in the art, so the control method and circuit connection will not be explained in detail.)

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
