Description

Technical Field

[0001] This invention relates to the field of workpiece machining technology, specifically to a composite CNC milling machine. Background Technology

[0002] Milling machines are versatile machine tools used to machine planes (horizontal and vertical), grooves (keyways, T-slots, dovetail grooves, etc.), geared parts (gears, splined shafts, sprockets), helical surfaces (threads, helical grooves), and various curved surfaces. They can also be used for machining rotating surfaces, internal holes, and for cutting operations.

[0003] Currently, existing CNC milling machines generate a large amount of waste chips during use, so they are generally equipped with high-pressure water guns to remove impurities from the workpiece surface. However, since water and impurities are mixed together, it is not easy to separate them, making the collection of impurities inconvenient. Therefore, further improvements are needed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a composite CNC milling machine. Through the design of the cleaning mechanism, when the first and second magnetic stones are within the magnetic attraction range, they will quickly attract each other. At this time, because the cleaning scraper is stopped abruptly, the cleaning scraper will flip upwards due to its own inertia. When the two come into contact, the cleaning scraper will drive the telescopic scraper to compress due to the degree of its flipping, thereby cleaning and scraping away impurities on the surface of the cleaning scraper, so as to collect impurities on the surface of the first filter screen more thoroughly.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a composite CNC milling machine, comprising a CNC milling machine body, wherein a cleaning mechanism is provided inside the CNC milling machine body, the cleaning mechanism comprising a rotating frame, the rotating frame being movably connected to the inside of the CNC milling machine body via a rotating shaft, a first filter screen being embedded inside the rotating frame, a first spring being fixedly connected to both sides of the bottom of the first filter screen, a sealing groove being provided inside the rotating frame, a second spring being fixedly connected to both sides of the sealing groove, a magnetic sealing plate being fixedly connected to the outer ends of the two second springs, magnetic blocks being fixedly connected to both sides of the inner cavity of the CNC milling machine body, a housing being fixedly connected to both sides of the top of the rotating frame, an elastic band being fixedly connected to one side wall of the inner cavity of the two housings, a first magnetic stone being fixedly connected to the bottom end of the two elastic bands, a rotating rod being rotatably connected between the two first magnetic stones, a cleaning scraper being fixedly connected to the outside of the rotating rod, a second magnetic stone being fixedly connected to one side wall of the inner cavity of the two housings, a fixed plate being fixedly connected to the top of the two housings, and a telescopic scraper being fixedly connected between the two fixed plates;

[0006] The rotating frame is equipped with a collection mechanism, which includes a collection frame located inside the rotating frame. The collection frame has a second filter screen embedded in both the front and rear side walls. Each of the two second filter screens has two sliding grooves. Each of the two sliding grooves has a sliding block slidably connected inside it. The outer ends of the two sliding blocks are fixedly connected to an arc-shaped plate.

[0007] Preferably, the CNC milling machine body has movable slots on both sides inside, and the bottom of the inner cavity of the two movable slots is fixedly connected to the bottom end of the two first springs, which facilitates the fixed connection of the first springs.

[0008] Preferably, the magnetic sealing plate and the magnetic block are magnetically set to opposite poles, and the magnetic sealing plate and the magnetic block are magnetically connected to facilitate attraction between them.

[0009] Preferably, the outer surface of the magnetic sealing plate is in contact with the inside of the magnetic block, and the bottom end of the cleaning scraper is in contact with the surface of the first filter screen, which facilitates the cleaning scraper to clean the first filter screen.

[0010] Preferably, the first and second magnetic stones are magnetically opposed, which facilitates their attraction.

[0011] Preferably, the outside of the collection frame is engaged with the inside of the first filter screen, which facilitates temporary support for the collection frame.

[0012] Preferably, a water outlet pipe is embedded on the rear side of the CNC milling machine body to facilitate water discharge.

[0013] Preferably, a drainage groove is provided on one side of the housing to facilitate water drainage.

[0014] This invention provides a composite CNC milling machine. It has the following beneficial effects:

[0015] 1. This composite CNC milling machine, through the design of the cleaning mechanism, can achieve the working effect of collecting impurities by scraping off all the impurities on the top of the first filter screen when the rotating frame is rotated to the limit, since the rotating frame is in an oblique state.

[0016] 2. This composite CNC milling machine, through the design of the cleaning mechanism, allows the first and second magnetic stones to quickly attract each other when they are within the magnetic attraction range. At this time, due to the sudden stop of the cleaning scraper, the cleaning scraper will flip upwards due to its own inertia. When the two come into contact, the cleaning scraper will drive the telescopic scraper to compress due to the degree of its flipping, thereby cleaning and scraping away impurities on the surface of the cleaning scraper, so as to collect impurities on the surface of the first filter screen more fully.

[0017] 3. This composite CNC milling machine, through the design of the collection mechanism, allows the magnetic sealing plate and the magnetic block to quickly attract each other when they are within the magnetic attraction range. At this time, due to the sudden stop of the collection frame, the sliding block and the arc-shaped clamping plate will quickly scrape upwards due to their own inertia, thereby achieving the effect of scraping off the impurities on the surface of the second filter screen. On the one hand, this can prevent the water flow speed from slowing down due to the presence of impurities. On the other hand, when the sliding block and the arc-shaped clamping plate reset, the vibration in contact with the second filter screen can also shake off the impurities, thus facilitating the overall collection of impurities.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0030] Please see Figure 1-9 This invention provides a technical solution: a composite CNC milling machine, including a CNC milling machine body 1, with a cleaning mechanism 2 inside the CNC milling machine body 1. The cleaning mechanism 2 includes a rotating frame 201, which is movably connected to the inside of the CNC milling machine body 1 via a rotating shaft. A first filter screen 202 is embedded inside the rotating frame 201, and first springs 203 are fixedly connected to both sides of the bottom of the first filter screen 202. A sealing groove is formed inside the rotating frame 201, and second springs 204 are fixedly connected to both sides inside the sealing groove. Magnetic sealing plates 205 are fixedly connected to the outer ends of the two second springs 204. Magnetic blocks 206 are fixedly connected to both sides of the cavity. Housings 207 are fixedly connected to both sides of the top of the rotating frame 201. Elastic bands 208 are fixedly connected to one side wall of the inner cavity of the two housings 207. First magnetic stones 209 are fixedly connected to the bottom of the two elastic bands 208. A rotating rod 210 is rotatably connected between the two first magnetic stones 209. A cleaning scraper 211 is fixedly connected to the outside of the rotating rod 210. Second magnetic stones 212 are fixedly connected to one side wall of the inner cavity of the two housings 207. A fixing plate 213 is fixedly connected to the top of the two housings 207. A telescopic scraper 214 is fixedly connected between the two fixing plates 213.

[0031] The rotating frame 201 is equipped with a collection mechanism 3. The collection mechanism 3 includes a collection frame 301, which is located inside the rotating frame 201. The front and rear side walls of the collection frame 301 are each equipped with a second filter screen 302. Each of the two second filter screens 302 has two sliding grooves. Each of the two sliding grooves is slidably connected to a sliding block 303. The outer ends of the two sliding blocks 303 are fixedly connected to an arc-shaped card plate 304.

[0032] The CNC milling machine body 1 has movable slots on both sides inside, and the bottom of the inner cavity of the two movable slots is fixedly connected to the bottom of the two first springs 203 respectively.

[0033] The magnetic sealing plate 205 and the magnetic block 206 are magnetically set to opposite poles, and the magnetic sealing plate 205 and the magnetic block 206 are magnetically connected.

[0034] The outer surface of the magnetic sealing plate 205 is in contact with the inside of the magnetic block 206, and the bottom end of the cleaning scraper 211 is in contact with the surface of the first filter screen 202.

[0035] The first magnetic stone 209 and the second magnetic stone 212 are magnetically set to opposite poles.

[0036] The outside of the collection frame 301 is engaged with the inside of the first filter screen 202.

[0037] A water outlet pipe 4 is embedded on the rear side of the CNC milling machine body 1.

[0038] A drainage groove is provided on one side of the housing 207.

[0039] When in use, when it is necessary to process the workpiece, the operator first places the workpiece inside the CNC milling machine body 1, and then opens the CNC milling machine body 1 to process the workpiece. When the workpiece is finished, the built-in high-pressure water gun will spray water to remove chips.

[0040] During this process, the sprayed water will spray debris onto the surface of the first filter screen 202. At this time, the debris and water will be separated by the first filter screen 202. When there is too much debris on the top of the first filter screen 202 and the first filter screen 202 is blocked, the water on the top of the first filter screen 202 will accumulate more and more. Due to the continuous increase in weight, the gravity will be greater than the magnetic attraction between the magnetic sealing plate 205 and the magnetic block 206, forcing the two to separate. At the same time, the rotating frame 201 will rotate to the lower right. At this time, the rotating frame 201 will drive the first spring 203 to compress. During the rotation of the rotating frame 201, a gap will be generated between it and the inside of the CNC milling machine body 1. Therefore, the second spring 204 will stretch and rebound during this process, causing the magnetic sealing plate 205 to adhere to the CNC milling machine body 1, thereby achieving the effect of blocking the water flow.

[0041] When the rotating frame 201 rotates to its limit, the cleaning scraper 211 will move downwards at an angle due to its own mass. The rotating rod 210 and the first magnetic stone 209 will move simultaneously, and the elastic band 208 will be stretched. During the movement of the cleaning scraper 211, all the impurities on the top of the first filter screen 202 will be scraped off until they fall into the collection frame 301, thus achieving the effect of collecting impurities.

[0042] During the above process, if the cleaning scraper 211 drives the first magnetic stone 209 to slide downwards and diagonally until the first magnetic stone 209 and the second magnetic stone 212 are within the magnetic attraction range, the two will attract each other quickly. At this time, because the cleaning scraper 211 is stopped suddenly, the cleaning scraper 211 will flip upwards by its own inertia and come into contact with the telescopic scraper 214. When the two come into contact, the cleaning scraper 211 will drive the telescopic scraper 214 to compress by the degree of its flipping, thereby cleaning and scraping the impurities on the surface of the cleaning scraper 211, so as to collect the impurities on the surface of the first filter screen 202 more fully.

[0043] When impurities are collected inside the collection frame 301, the water flow from the top of the first filter screen 202 is also simultaneously drawn into the collection frame 301. Therefore, the water will pass through the second filter screen 302 again. As the water pressure accumulated at the top of the first filter screen 202 gradually decreases, the first spring 203 will stretch and reset, causing the rotating frame 201 to perform a horizontal reset. During this process, as the reset speed of the rotating frame 201 increases, when the magnetic sealing plate 205 and the magnetic block 206 are in a certain position... When the magnetic attraction range is reached, the two will quickly attract each other. At this time, due to the sudden stop of the collection frame 301, the sliding block 303 and the arc-shaped plate 304 will quickly scrape upwards by their own inertia, thereby achieving the effect of scraping off the impurities on the surface of the second filter screen 302. On the one hand, this can prevent the water flow speed from slowing down due to the presence of impurities. On the other hand, when the sliding block 303 and the arc-shaped plate 304 are reset, the vibration in contact with the second filter screen 302 can shake off the impurities, so as to facilitate the overall collection.

[0044] Once the impurities have been collected, the water will flow away through the outlet pipe 4. Then, the staff can remove the collection frame 301 from inside the rotating frame 201.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
