[0020] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the exploded structure of a waterproof structure for a machine tool protective door 100 according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the combined structure of an embodiment of the waterproof structure for a machine tool protective door 100 of the present application. The waterproof structure includes a first water retaining baffle 10, a second water retaining baffle 20 and a scraper assembly 30. Specifically: The first water retaining baffle 10 is arranged on the back side of the protective door 100; wherein, an extension support plate 11 perpendicular to the surface of the first water retaining baffle 10 is provided at the bottom of the first water retaining baffle 10, and the extension support plate 11 is used to receive the residual liquid between the protective door 100 and the first water retaining baffle 10.

[0021] Specifically, the waterproof structure for the machine tool protective door 100 proposed in this application is applied to an automatic machine tool, which includes a processing cabin, which is used for processing workpieces. When the protective door 100 is in a closed state, it is used to prevent splashing liquid and iron filings in the processing cabin from entering the space outside the processing cabin. In addition, after the processing is completed, the protective door 100 is switched from a closed state to an open state, and the back of the protective door 100 in the open state is close to the side surface of the above-mentioned first water retaining baffle 10, and the residual liquid on the back of the protective door 100 flows along the gap between the protective door 100 and the first water retaining baffle 10 into the extended support plate 11 at the bottom of the first water retaining baffle 10 to prevent some residual liquid from entering the interior of the automatic machine tool, thereby improving the stability of the operation of the automatic machine tool.

[0022] The second water retaining baffle 20 is fixedly connected to the side of the first water retaining baffle 10 ; wherein the surface of the second water retaining baffle 20 intersects with the surface of the first water retaining baffle 10 .

[0023] Specifically, the side of the second water retaining baffle 20 is fixed and sealed to the side of the first water retaining baffle 10. The second water retaining baffle 20 is used to separate the processing chamber of the automatic machine tool from the internal space of the automatic machine tool to prevent liquid and iron filings in the processing chamber from entering the interior of the automatic machine tool during processing.

[0024] The scraper assembly 30 includes a scraper plate 31 and a fixed pressure plate 32 that match each other; wherein the fixed pressure plate 32 is used to fix the scraper plate 31 on the edge of the second water retaining baffle 20.

[0025] Specifically, the fixed pressure plate 32 fixes the scraper plate 31 to the second water retaining baffle 20, and at least a portion of the scraper plate 31 in the fixed state protrudes from the edge of the second water retaining baffle 20. When the protective door 100 is opened, at least a portion of the protruding scraper plate 31 is in contact with the back of the protective door 100 to remove residual liquid and waste materials such as iron filings on the back of the protective door 100, thereby ensuring that the back of the protective door 100 is clean.

[0026] The waterproof structure for the machine tool protective door 100 proposed in this application includes a first water retaining baffle 10, a second water retaining baffle 20 and a scraper assembly 30. During the processing, the protective door 100 is in a closed state to prevent some liquids and iron filings from entering the space outside the processing chamber. After the processing is completed, the protective door 100 is switched to an open state. The back of the protective door 100 in the open state is close to the first water retaining baffle 10. The residual liquid on the back of the protective door 100 flows along the gap between the protective door 100 and the first water retaining baffle 10 into the extended support plate 11 located at the bottom of the first water retaining baffle 10 to improve the waterproof performance of the automatic machine tool. In addition, the scraper assembly 30 includes a scraper plate 31 fixed to the edge of the second water retaining baffle 20. When the protective door 100 is opened or closed, the scraper plate 31 scrapes off the liquid or iron filings attached to the back of the protective door 100 to ensure the cleanliness of the back of the protective door 100 and improve the smoothness of the movement of the protective door 100.

[0027] In one embodiment, the waterproof structure proposed in this application is applied to an automatic machine tool including a processing chamber. In the direction of movement of the protective door 100, the extension plate 11 includes a first end and a second end disposed opposite each other, the first end being higher than the second end, and the second end being in communication with the processing chamber.

[0028] Specifically, the protective door 100 on the automatic machine tool supports lateral movement. In the direction of movement, the extension support plate 11 at the bottom of the first water-retaining baffle 10 includes a first end and a second end that are arranged opposite each other. The first end is higher than the second end, and the second end is connected to the processing chamber, so that the extension support plate 11 is tilted toward the processing chamber. When residual liquid between the back of the protective door 100 and the first water-retaining baffle 10 flows into the extension support plate 11, the tilted extension support plate 11 helps the residual liquid flow into the processing chamber, preventing the residual liquid from flowing into the interior of the processing machine tool.

[0029] In some implementation scenarios, the inclination angle between the extension support plate 11 and the horizontal plane is 3°. Of course, in other implementation scenarios, the corresponding inclination angle of the extension support plate 11 can also be set according to actual conditions.

[0030] In one embodiment, a limit folding plate 12 is provided on an edge of the first water retaining baffle 10 away from the processing chamber. When the protective door 100 is in an open state, one side of the protective door 100 is in contact with the limit folding plate 12.

[0031] Specifically, to limit the lateral movement of the protective door 100, a protruding limit flap 12 is provided on the edge of the first water retaining baffle 10 away from the processing chamber. When the protective door 100 is in a fully open state, one side of the protective door 100 is in contact with the limit flap 12.

[0032] In some implementation scenarios, the width of the limiting flap 12 is consistent with the thickness of the protective door 100. Alternatively, the width of the limiting flap 12 is slightly greater than the thickness of the protective door 100, so that the limiting flap 12 protects one side of the protective door 100.

[0033] In one embodiment, the waterproof structure for the machine tool protective door 100 proposed in this application further includes a moving assembly 40. The moving assembly 40 is connected to the limiting folding plate 12. The moving assembly 40 is used to support the protective door 100 and drive the protective door 100 to move.

[0034] In some implementation scenarios, the above-mentioned moving assembly 40 includes a moving guide rail 41 and multiple rollers 42. One end of the moving guide rail 41 is fixedly connected to the limiting folding plate 12, and the other end of the moving guide rail 41 is fixedly connected to one side of the processing chamber.

[0035] Furthermore, a groove matching the roller 42 is provided at the bottom of the protective door 100 , and at least a portion of the roller 42 is located in the groove. The roller 42 rotates to drive the protective door 100 to move along the movable guide rail 41 .

[0036] Specifically, the movable guide rail 41 includes two opposing ends: one end is fixedly connected to the limiting flap 12 on the first water retaining baffle 10, and the other end is fixedly connected to the inner wall of the processing chamber on the side away from the first water retaining baffle 10. A plurality of rollers 42 are provided on the movable guide rail 41, and grooves matching the rollers 42 are provided at the bottom of the protective door 100, which are configured to accommodate at least a portion of the rollers 42. During use, a lateral force is applied to the protective door 100, causing the rollers 42 to rotate, thereby driving the protective door 100 along the movable guide rail 41, thereby opening or closing the protective door 100.

[0037] Optionally, to improve the efficiency of opening or closing the protective door 100, a handle (not shown) is provided on the front of the protective door 100. The protective door 100 is opened or closed by applying a force to the handle.

[0038] In one embodiment, the moving assembly 40 further includes a drive mechanism (not shown) that is drivably connected to at least one roller 42. The drive mechanism is configured to rotate the connected roller 42 and drive the protective door 100 along the movable guide rail 41, thereby automatically opening or closing the protective door 100 and saving manpower.

[0039] In some implementation scenarios, the driving mechanism is a motor, and the driving mechanism is connected to at least one roller 42 via a transmission member. The transmission member can be a belt or a gear.

[0040] In one embodiment, see Figure 3 , Figure 3This is a schematic diagram of another embodiment of the waterproof structure for a machine tool protective door 100 according to the present application. To facilitate the removal of residual liquid and waste materials such as iron filings from the processing chamber, the waterproof structure for the machine tool protective door 100 proposed in the present application also includes a drainage mechanism 50 and a diversion groove 60. The drainage mechanism 50 is disposed at the bottom of the second water retaining baffle 20. The projection of the drainage mechanism 50 on the horizontal plane overlaps at least partially with the diversion groove 60. The drainage mechanism 50 is used to drain residual liquid from the processing chamber into the diversion groove 60.

[0041] In some implementation scenarios, the drainage mechanism 50 is designed in a funnel shape, and the residual liquid and waste materials such as iron filings in the processing chamber flow along the bottom surface of the processing chamber to the drainage mechanism 50, and enter the diversion groove 60 through the drainage mechanism 50. The liquid in the diversion groove 60 is filtered and reused.

[0042] In one embodiment, the scraper plate 31 includes a scraper edge, at least a portion of which is in contact with the back surface of the protective door 100 .

[0043] Specifically, the scraper plate 31 includes a scraping edge for removing residual liquid and waste materials such as iron filings from the back of the protective door 100. When the scraper plate 31 is fixed to the second water retaining baffle 20 by the fixed pressure plate 32, the scraping edge protrudes from the edge of the second water retaining baffle 20, and at least a portion of the scraping edge is in contact with the back of the protective door 100, thereby improving the cleaning effect on the back of the protective door 100.

[0044] In some implementation scenarios, the scraping edge is made of rubber to reduce the probability of damaging the protective door 100 during the scraping process.

[0045] In one embodiment, in order to optimize the protection of the processing chamber by the protective door 100, the protective door 100 is arranged in an "L" shape, that is, the protective door 100 includes a first protective plate and a second protective plate that are bent. In the closed state, the first protective plate of the protective door 100 is used to protect the front of the processing chamber to prevent liquids, iron filings and other waste materials from splashing out from the front of the processing chamber; and, in the closed state, the second protective plate of the protective door 100 is used to protect the top of the processing chamber to prevent liquids, iron filings and other waste materials from splashing out from the top of the processing chamber. In addition, in the open state, the first protective plate is close to the first water retaining baffle 10, and the first protective plate is parallel to the first water retaining baffle 10.

[0046] In some implementation scenarios, when the protective door 100 is in an "L" shape, the scraper plate 31 in the scraper assembly 30 is also in an "L" shape, that is, the scraper plate 31 includes a first scraper edge and a second scraper edge, and the extension direction of the first scraper edge intersects with the extension direction of the second scraper edge. When the protective door 100 is opened or closed, at least a portion of the first scraper edge is in contact with the first protective plate of the protective door 100, and as the protective door 100 moves laterally, the first scraper edge removes residual liquid and waste materials such as iron filings on the back of the first protective plate; and at least a portion of the second scraper edge is in contact with the second protective plate of the protective door 100, and as the protective door 100 moves laterally, the second scraper edge removes residual liquid and waste materials such as iron filings on the back of the second protective plate. In addition, in order to improve the stability of the scraper plate 31, the fixed pressure plate 32 is also in an "L" shape.

[0047] In one embodiment, see Figure 4 , Figure 4 This is a schematic diagram of the structure of a fixed pressure plate corresponding to one embodiment of the present application. The fixed pressure plate 32 includes a first pressing portion 321 and a second pressing portion 322, with the first pressing portion 321 and the second pressing portion 322 being perpendicular to each other. When the protective door 100 is closed, the second pressing portion 322 is in contact with the back of the protective door 100.

[0048] In some implementations, a plurality of first openings are provided on the first crimping portion 321 of the fixed pressure plate 32, a second opening matching the first opening is provided on the scraper plate 31, and a third opening matching the first opening is provided on the second water retaining baffle 20. The scraper plate 31 is fixed by sequentially passing fixing bolts through the matching first openings, second openings, and third openings.

[0049] Furthermore, the plane of the second crimping portion 322 of the fixed pressure plate 32 is parallel to the plane of the back surface of the protective door 100. When the protective door 100 is closed, the projection of the second crimping portion 322 in the first direction overlaps at least partially with the protective door 100. The second crimping portion 322 is provided to cover the gap between the protective door 100 and the second water retaining baffle 20. The first direction is perpendicular to the surface of the second crimping portion 322 and faces the protective door 100.

[0050] Specifically, when the protective door 100 is closed, the second crimping portion 322 is fitted against the back of the protective door 100 so that the second crimping portion 322 covers the gap between the protective door 100 and the second water retaining baffle 20, thereby preventing residual liquid and waste such as iron filings during processing from entering the interior of the automatic machine tool through the gap, thereby improving the sealing performance of the automatic machine tool.

[0051] Optionally, to avoid affecting the opening or closing of the protective door 100, an appropriate distance is maintained between the protective door 100 and the second crimping portion 322. That is, when the protective door 100 is closed, a first gap exists between the back surface of the protective door 100 and the second crimping portion 322, and the length of the first gap is less than a predetermined length threshold. For example, the predetermined length threshold may be 1 mm.

[0052] In one embodiment, the first water retaining baffle 10 is provided with a plurality of through-holes. Furthermore, the waterproof structure for the machine tool protective door 100 proposed in this application further includes a blower assembly (not shown). When the protective door 100 is in the open state, the blower assembly is disposed on the side of the first water retaining baffle 10 away from the protective door 100. The blower assembly includes a blower port facing the first water retaining baffle 10. The gas released from the blower port is blown toward the back of the protective door 100 through the through-holes in the first water retaining baffle 10, thereby quickly removing residual liquid and waste materials such as iron filings on the back of the protective door 100.

[0053] In one embodiment, a detection sensor is provided on the limiting flap 12 of the first water retaining baffle 10. This detection sensor is used to detect whether the protective door 100 is in the open or closed state. The detection sensor is coupled to the blower assembly. When the detection sensor detects that the protective door 100 has switched from the closed state to the open state, the detection sensor sends an operating signal to the blower assembly, automatically controlling the blower assembly to release gas through the through-hole of the first water retaining baffle 10 toward the back of the protective door 100.

[0054] In some implementations, the detection sensor may be a laser sensor or a contact sensor. When the detection sensor is a laser sensor, during the processing process, the detection sensor detects the distance between one side of the protective door 100 and the limiting flap 12 in real time. If the distance is less than a preset distance threshold, indicating that the protective door 100 is fully open, the blowing assembly releases gas. Alternatively, when the detection sensor is a contact sensor, the blowing assembly releases gas when one side of the protective door 100 contacts the detection sensor after the protective door 100 is fully opened.

[0055] In one embodiment, the waterproof structure for a machine tool protective door 100 proposed in this application further includes a protective housing (not shown). A receiving cavity is formed between the protective housing and the first water-retaining baffle 10. When the protective door 100 is open, the protective door 100 is located within the receiving cavity.

[0056] Specifically, the protective shell is located on the outside of the protective door 100 and is used to provide a certain degree of protection for the front of the protective door 100 .

[0057] The present application also proposes a mobile automatic machine tool, which includes the waterproof structure for the machine tool protective door mentioned in any of the above embodiments.

[0058] Specifically, the automatic machine tool includes a processing chamber, in which a processing tool is disposed. The processing chamber is used to accommodate a workpiece to be processed, and the workpiece is processed using the processing tool. Furthermore, because the automatic machine tool includes the waterproof structure described in any of the above-mentioned embodiments, the automatic machine tool has excellent waterproof performance and high stability.

[0059] The above description is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
