Description

Technical Field

[0001] The invention relates to a self-cleaning structure, in particular to an external chip self-cleaning mechanism suitable for an intelligent automatic machine tool. Background Art

[0002] like Figure 1 , 2 As shown in the figure, a high-speed rotating machine tool is a precision machine tool for automobile wheel hub processing. The spindle speed is 1500 rpm-2000 rpm. During the processing, the workpiece rotates at high speed with the spindle, generating a very high wind speed. The coolant sprayed on the workpiece will also generate high-speed water mist. The speed at which the chips generated by the processing fly out is also very high. The high wind speed will generate high wind pressure. The high wind pressure, high-speed water mist and high-speed chips make the sealing effect of the commonly used sealing form very poor. The coolant and chips are easy to leak out of the guide rail, lead screw and sliding door. The accumulation of chips will seriously affect the accuracy and life of the lead screw and guide rail, and the chips and coolant leaking out of the machine tool will seriously damage the machine tool. It pollutes the surrounding environment, affects the working environment of the staff, and even endangers the personal safety of the staff in serious cases. Therefore, the leakage of coolant and chips must be prevented. However, in the process of opening and closing the sliding door, coolant and chips will inevitably accumulate on both sides of the sliding door. The coolant and chips accumulated on both sides of the sliding door need to be cleaned. Manual cleaning is inefficient and costly. A structure for cleaning coolant and chips with high efficiency, low cost and simple structure is needed. At the same time, the inner cavity of the machine tool needs to be depressurized, and the sealing effect of the machine tool sliding door must be guaranteed while depressurizing, so as to further improve the reliability of the machine tool. These are technical problems that need to be solved urgently. Summary of the invention

[0003] The purpose of the present invention is to provide an external chip self-cleaning mechanism suitable for intelligent automatic machine tools, which can automatically clean the coolant and chips accumulated on both sides of the sliding door. The cleaning efficiency is high, the cost is low, and the structure is simple. It can also reduce the pressure in the inner cavity of the machine tool and ensure the sealing effect of the machine tool sliding door while reducing the pressure.

[0004] The technical solution of the present invention is: an external chip self-cleaning mechanism suitable for intelligent automatic machine tools, including a sliding door, a main body and a sliding rail, the sliding door and the main body are slidably connected by the sliding rail, and is characterized in that: a self-cleaning structure is arranged between the two sides of the sliding door and the main body, and a sealing structure and a decompression structure are arranged between the bottom of the sliding door and the main body. The self-cleaning structure is used to clean the coolant and chips accumulated on both sides of the sliding door, and the sealing structure is used to prevent the chips and coolant from leaking from under the sliding door. The gas in the main body is connected to the external space of the main body through the decompression structure, thereby reducing the air pressure inside the main body.

[0005] Further, the self-cleaning structure includes a nozzle and a collection trough. The collection trough is located on both sides of the sliding door, the nozzle is located above the collection trough, the bottom surface of the collection trough is an inclined surface that slopes towards the closed position of the sliding door, and the downstream end of the collection trough communicates with the internal space of the main body.

[0006] Further, the sliding door includes a vertical plate, a horizontal plate, and a lower edge plate. The main body includes an inner protection plate and an outer protection plate. The lower edge plate is disposed between the inner protection plate and the outer protection plate, and there are gaps between the inner protection plates and between the lower edge plate and the outer protection plate.

[0007] Further, the pressure reduction structure includes the gap between the lower edge plate and the outer protection plate, a communication space, and a communication port. The communication port communicates with the inner cavity of the main body, the gap communicates with the external space of the main body, and the inner cavity of the main body communicates with the gap through the communication port and the communication space.

[0008] Further, the downstream end of the collection trough communicates with the communication space of the pressure reduction structure.

[0009] Further, the communication space internally has an upper diversion plate and a lower diversion plate that slope downwards, and a baffle plate is fixedly connected to the upper diversion plate.

[0010] Further, the sealing structure is disposed in the gap between the lower edge plate and the inner protection plate.

[0011] Further, the sealing structure includes a sealing structure body and reinforcing ribs, and the sealing structure body is fixedly connected to the reinforcing ribs.

[0012] Further, one side of the sealing structure body is fixedly connected to the lower edge plate, and the other side of the sealing structure body is in close contact with the inner protection plate.

[0013] Further, the sealing structure further includes a support seat. The support seat is fixedly connected to the inner protection plate. The lower part of the sealing structure body is in close contact with the upper part of the support seat, and the reinforcing ribs are in close contact with the side surface of the support seat.

[0014] The present invention has the following beneficial effects: The self-cleaning structure flushes the accumulated coolant and chips on both sides of the sliding door back into the machine tool interior, and finally discharges them through the chip conveyor. Its structure is simple, with high working efficiency and labor savings. The gas in the machine tool cavity is connected to the external space of the machine tool through the pressure reduction structure. Under the action of wind pressure, air flows from the machine tool cavity to the outside of the machine tool, thereby reducing the wind 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 due to the action of gravity and will not leak from the pressure reduction structure. Due to the existence of the sealing structure, the chips and coolant accumulate above the sealing structure and will not leak, ensuring the sealing effect of the machine tool sliding door while reducing the pressure in the machine tool cavity, preventing environmental pollution and ensuring personnel safety. The chips and coolant accumulated on both sides of the sliding door are transported to the chip conveyor for discharge through the self-cleaning structure, with high cleaning efficiency and improved reliability of the machine tool.

[0024] As Figure 3-6 shown, an external chip self-cleaning mechanism adapted to an intelligent automation machine tool includes a sliding door 1 and the main body 2 of the machine tool. The sliding door 1 is slidably connected to the main body 2 through a slide rail. Self-cleaning structures are provided between both sides of the sliding door 1 and the main body 2, and a sealing structure 5 and a pressure reducing structure 6 are provided between the lower part of the sliding door 1 and the main body 2. The self-cleaning structure is used to clean the coolant and chips accumulated on both sides of the sliding door. The sealing structure is used to prevent chips and coolant from leaking from under the sliding door. The gas in the inner cavity of the main body is communicated with the external space of the machine tool through the pressure reducing structure, thereby reducing the air pressure inside the main body.

[0025] The self-cleaning structure includes a nozzle 3 and a collection trough 4. The collection trough 4 is located on both sides of the sliding door. The nozzle 3 is located above the collection trough 4. The bottom surface of the collection trough is an inclined surface, inclined towards the closing position of the sliding door. The downstream end of the collection trough 4 communicates with the internal space of the main body. The liquid ejected by the nozzle 3 flushes the accumulated coolant and chips in the collection trough 4 back into the internal space of the main body and is finally discharged through a chip conveyor 100.

[0026] The sliding door includes a vertical plate 101, a horizontal plate 102 and a lower edge plate 103. The horizontal plate 102 is perpendicular to the vertical plate 101, and the lower edge plate 103 is perpendicular to the horizontal plate 102. The main body 2 includes an inner protection plate 21 and an outer protection plate 22. The lower edge plate 103 is arranged between the inner protection plate 21 and the outer protection plate 22. There is a gap between the inner protection plate 21, the lower edge plate 103 and the outer protection plate 22. Preferably, the three plates are arranged in parallel. The pressure reduction structure 6 includes a gap 61 between the lower edge plate 103 and the outer protection plate 22, a communication space 62 and a communication port 63. The communication port 63 is communicated with the inner cavity of the machine tool, and the gap 61 is communicated with the external space of the machine tool. The inner cavity of the machine tool is communicated through the communication port 63, the communication space 62 and the gap 61, so as to reduce the pressure in the inner cavity of the machine tool. A sealing structure 5 is arranged in the gap between the lower edge plate 103 and the inner protection plate 21.

[0027] The downstream end of the collection tank 4 is communicated with the communication space 62 of the pressure reduction structure 6. The liquid sprayed by the nozzle 3 flushes the accumulated coolant and chips in the collection tank 4 into the communication space 62, and then flushes back into the inner cavity of the machine tool through the communication port 63 and is finally discharged through the chip conveyor 100. In order to make the flow effect of the coolant and chips better, the communication space is provided with an upper diversion plate 11 and a lower diversion plate 12 that are inclined downward. In order to prevent backflow, a baffle plate 10 is fixedly connected to the upper diversion plate 11.

[0028] The slide rail includes a guide rail slider 7 and a linear guide rail 8. The guide rail slider 7 is fixedly connected to the sliding door 1, and the linear guide rail 8 is fixedly connected to the main body 2. The guide rail slider 7 is slidably connected to the linear guide rail 8, so that the sliding door 1 slides on the main body 2. Further, the linear guide rail 8 is fixedly connected to the outer protection plate 22, and the guide rail slider 7 is fixedly connected to the horizontal plate 102 of the sliding door 1.

[0029] The sealing structure 5 includes a sealing structure body 51 and a reinforcing rib 52 that are fixedly connected. The sealing structure body 51 is in a square shape with a hole in the middle, and the reinforcing rib 52 is an L-shaped structure. One side of the sealing structure body 51 is fixedly connected to the lower edge plate 103, and the other side of the sealing structure body 51 is in close contact with the inner protection plate 21. The sealing structure further includes a support seat 53, and the support seat 53 is fixedly connected to the inner protection plate 21. The lower part of the sealing structure body 51 is in close contact with the upper part of the support seat 53, and the reinforcing rib 52 is in close contact with the side surface of the support seat 53, which increases the strength of the sealing structure and further increases the sealing effect.

[0030] The self-cleaning structure flushes the accumulated coolant and chips on both sides of the sliding door 1 back into the machine tool interior, and finally discharges them through the chip conveyor 100. Its structure is simple, with high working efficiency and labor savings. The gas in the machine tool cavity is connected to the external space of the machine tool through the pressure reduction structure 6. Under the action of wind pressure, air flows from the machine tool cavity to the outside of the machine tool, thereby reducing the wind 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 due to the action of gravity and will not leak from the pressure reduction structure 6. Due to the existence of the sealing structure 5, the chips and coolant accumulate above the sealing structure 5 and will not leak. While reducing the pressure in the machine tool cavity, the sealing effect of the machine tool sliding door is ensured, preventing environmental pollution and ensuring personnel safety. The chips and coolant accumulated on both sides of the sliding door are transported to the chip conveyor for discharge through the self-cleaning structure, with high cleaning efficiency and improved reliability of the machine tool.
