Description

Technical Field

[0001] The present invention relates to a self-cleaning mechanism, and particularly to an internal chip self-cleaning mechanism adapted to intelligent automated machine tools. Background Art

[0002] As Figure 1 、 2 shown, a high-speed rotating machine tool, a precision machine tool for machining automobile wheels, with a spindle speed of 1500 - 2000 revolutions per minute. During the machining process, the workpiece rotates at a high speed along with the spindle, generating a very high wind speed. When the coolant is sprayed onto the workpiece, it will also generate high-speed water mist. The flying speed of the chips generated during machining is also extremely high. The high wind speed will generate high wind pressure, and the high wind pressure causes the internal space and the overall structure of the machine tool to bear a great deal of pressure, making the machine tool prone to damage. Therefore, it is necessary to decompress the internal space of the machine tool. Moreover, due to the high wind pressure, high-speed water mist, and high-speed chips, the coolant and chips are likely to leak outside the machine tool. Outside the guide rails, lead screws, and sliding doors, chip accumulation will seriously affect the accuracy and service life of the lead screws and guide rails. The chips and coolant leaked outside the machine tool will seriously contaminate the surrounding environment, affecting the working environment of the staff, and seriously endangering the personal safety of the staff. Therefore, while decompressing the internal space of the machine tool, it is also necessary to prevent the leakage of the coolant and chips, and clean up the accumulated coolant and chips. Manual cleaning has low efficiency and high cost. There is a need for a structure that can clean the coolant and chips with high efficiency, low cost, and simple structure. At the same time, it is also necessary to decompress the inner cavity of the machine tool and ensure the sealing effect of the sliding door of the machine tool while decompressing, so as to further improve the reliability of the machine tool. These are all technical problems that urgently need to be solved. Summary of the Invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide an internal chip self-cleaning mechanism adapted to intelligent automated machine tools, which can automatically clean the accumulated coolant and chips inside the machine tool, with high cleaning efficiency, low cost, and simple structure, and can decompress the inner cavity of the machine tool and ensure the sealing effect of the machine tool while decompressing.

[0004] The technical solution of the present invention is: an internal chip self-cleaning mechanism adapted to intelligent automated machine tools, characterized in that: it includes a self-cleaning decompression sealing structure and a machine tool main body. The self-cleaning decompression sealing structure is arranged inside the machine tool main body and is arranged along the spindle direction of the machine tool. The upper part of the self-cleaning decompression sealing structure is a rectangular space, and the lower part is a funnel-shaped space.

[0005] Further, one side of the rectangular space close to the inside of the machine tool is a protective plate, and the side close to the outside of the machine tool is a ventilation plate.

[0006] Further, a funnel-shaped space is fixedly connected to the lower part of the rectangular space. The funnel-shaped space includes a side plate close to the inside of the machine tool, and the side plate is fixedly connected to the protective plate, and an inclined plate close to the outside of the machine tool. The inclined plate inclines from top to bottom towards the side plate.

[0007] Further, a lower edge plate is arranged at one end of the inclined plate close to the side plate. The part of the side plate corresponding to the lower edge plate is recessed towards the inside of the machine tool to form a recessed part. A gap is formed between the recessed part, the inclined plate and the lower edge plate.

[0008] Further, the funnel-shaped space also has an inclined back plate, and the back plate is fixedly connected to the side plate and the inclined plate.

[0009] Further, a plurality of nozzles are arranged at the connection part of the rectangular space and the funnel-shaped space.

[0010] The present invention has the following beneficial effects: The self-cleaning decompression sealing structure flushes the accumulated coolant and chips back into the machine tool interior, and finally discharges them through the chip conveyor. Its structure is simple, the working efficiency is high, and manual labor is saved. The gas in the machine tool cavity is communicated with the external space of the machine tool through the self-cleaning decompression sealing structure, thereby reducing the air pressure generated in the machine tool cavity due to the high-speed rotation of the workpiece. The chips and coolant carried out by the air flow fall back to the bottom of the machine tool through the gap due to gravity and the cleaning liquid, and will not leak from the self-cleaning decompression sealing structure. Since the gap is a vertical slit, gas can pass through it, but coolant and chips are difficult to pass through, further enhancing the sealing effect. Description of the Drawings

[0016] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0018] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] As Figures 3-5 shown, an internal chip self-cleaning mechanism adapted to an intelligent automation machine tool includes a self-cleaning pressure-reducing sealing structure 1 and a machine tool body 2. The self-cleaning pressure-reducing sealing structure 1 is arranged inside the machine tool body 2 and two are arranged along the spindle direction of the machine tool. A rectangular space 3 is formed in the upper part of the self-cleaning pressure-reducing sealing structure 1, and a funnel-shaped space 4 is formed in the lower part.

[0020] One side of the rectangular space 3 close to the inside of the machine tool is a protective plate 31, and the side close to the outside of the machine tool is a ventilation plate 32. The protective plate 31 blocks most of the coolant and chips generated inside the machine tool inside the machine tool, and the ventilation plate 32 enables the space inside and outside the machine tool to circulate, thereby reducing the wind pressure inside the machine tool.

[0021] Although the protective plate 31 can block most of the coolant and chips inside the machine tool, a small amount of coolant and chips will still enter the rectangular space 3 through the connection parts of the protective plate and some installation parts. Therefore, a funnel-shaped space 4 is connected to the lower part of the rectangular space 3. The side plate 41 of the funnel-shaped space 4 close to the inside of the machine tool is fixedly connected to the protective plate 31. The inclined plate 42 close to the outside of the machine tool inclines from top to bottom towards the side plate 41. A lower edge plate 43 is arranged at one end of the inclined plate 42 close to the side plate 41. The part of the side plate 41 corresponding to the lower edge plate 43 is recessed towards the inside of the machine tool to form a recess 44. A gap 5 is formed between the recess 44, the inclined plate 42 and the lower edge plate 43. The coolant and chips in the rectangular space 3 and the funnel-shaped space 4 flow back to the internal space of the machine tool through the gap 5 and are finally discharged through the chip conveyor 100.

[0022] The funnel-shaped space 4 also has an inclined back plate 45, and the back plate 45 is fixedly connected to the side plate 41 and the inclined plate 42.

[0023] Coolant and chips will flow in the clearance 5 under the action of gravity. To further enhance the cleaning effect, a plurality of nozzles are provided at the connection part of the rectangular space 3 and the funnel-shaped space 4. The liquid ejected from the nozzles can flush the coolant and chips into the clearance and flow back into the machine tool interior. The self-cleaning effect is good, and it can be cleaned at any time during operation without the need to stop the machine.

[0024] The self-cleaning decompression sealing structure flushes the accumulated coolant and chips back into the machine tool interior, and finally discharges them through the chip conveyor 100. Its structure is simple, the working efficiency is high, and labor is saved. The gas in the machine tool cavity is communicated with the external space of the machine tool through the self-cleaning decompression sealing structure, thereby reducing the air pressure generated in the machine tool cavity due to the high-speed rotation of the workpiece. The chips and coolant carried out by the air flow fall back to the bottom of the machine tool through the clearance 5 due to gravity and the action of the cleaning liquid and will not leak from the self-cleaning decompression sealing structure. Since the clearance 5 is a vertical slit, gas can pass through it, but coolant and chips are difficult to pass through, further enhancing the sealing effect.

[0025] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
