DETAILED DESCRIPTION

[0023] The following combination Figure 1-Figure 5This application is described in further detail.

[0024] The present application embodiment discloses a gantry gear-removing machine. Figure 1 and Figure 2 The gantry gear-shoveling machine includes a gantry 1 and a fixed plate 2. The fixed plate 2 is slidably arranged on the gantry 1 in the vertical direction. The driving method of the fixed plate 2 is the existing technology and will not be described in detail here. A tool holder pad 3 and a mounting seat 21 are fixedly installed on the fixed plate 2. The tool holder pad 3 is located above the mounting seat 21. The horizontal distance from the side of the tool holder pad 3 close to the workbench where the substrate is placed to the workbench is smaller than the horizontal distance from the side of the mounting seat 21 close to the workbench to the workbench, so that the side of the tool holder pad 3 close to the workbench extends out of the mounting seat 21; a scraper 4 is fixedly installed on the lower surface of the mounting seat 21, so that the tool holder pad 3 is located above the scraper 4. In order to save costs and meet the requirements of scraping multiple substrates at the same time, a plurality of scrapers 4 are spaced apart along the length direction of the tool holder pad 3. Specifically, two scrapers 4 are provided on the mounting seat 21.

[0025] Reference Figure 2 and Figure 3 A liquid storage chamber 5 is provided in the tool holder pad 3, and the liquid storage chamber 5 is located on the side of the tool holder pad 3 close to the workbench, so that the liquid storage chamber 5 is staggered with the mounting hole on the tool holder pad 3. A liquid inlet pipe 6 is passed through the tool holder pad 3, and the liquid inlet pipe 6 is connected with the liquid storage chamber 5. The liquid inlet pipe 6 is used to communicate with an external cutting fluid source, so as to facilitate the introduction of cutting fluid into the liquid storage chamber 5. A plurality of fixed nozzles 7 are fixedly installed on the side of the tool holder pad 3 close to the scraper 4, and the arrangement direction of the plurality of fixed nozzles 7 is parallel to the length direction of the scraper 4. The fixed nozzles 7 are connected with the liquid storage chamber 5, and the fixed nozzles 7 are located on the side of the mounting seat 21 close to the workbench, and the fixed nozzles 7 are aligned with the upper end of the scraper 4, so as to facilitate the flow of cutting fluid to the scraper 4; in the embodiment of the present application, each scraper 4 corresponds to two fixed nozzles 7, and the two fixed nozzles 7 corresponding to each scraper 4 are located at both ends of the scraper 4, so as to facilitate the cooling and lubrication of the scraper 4.

[0026] Reference Figure 2 and Figure 3An adjusting hole 8 is provided on one side of the liquid storage chamber 5 close to the scraper 4. The adjusting hole 8 corresponds to the scraper 4 one by one. The adjusting hole 8 is located between the two ends of the corresponding scraper 4. The adjusting hole 8 is a strip hole. The length direction of the adjusting hole 8 is parallel to the arrangement direction of the multiple fixed nozzles 7. A sealing plate 9 is slidingly provided on the bottom wall of the liquid storage chamber 5. The sealing plate 9 corresponds to the adjusting hole 8 one by one. The sealing plate 9 is used to close the corresponding adjusting hole 8. The cross-section of the sealing plate 9 is rectangular. The length direction of the sealing plate 9 is parallel to the length direction of the adjusting hole 8. The sliding direction of the sealing plate 9 is parallel to the arrangement direction of the multiple fixed nozzles 7. A mobile nozzle 26 is pierced on the sealing plate 9. The mobile nozzle 26 extends outside the corresponding adjusting hole 8 and is connected to the liquid storage chamber 5. An adjusting member for adjusting the sealing plate 9 to drive the mobile nozzle 26 to slide is provided on the knife seat pad 3.

[0027] When in use, the sealing plate 9 is adjusted to slide along the corresponding adjustment hole 8 through the adjustment piece, and the mobile nozzle 26 is adjusted to the desired position according to the shape, size or cutting conditions of the substrate. The cooperation between the mobile nozzle 26 and the fixed nozzle 7 helps to ensure the coverage of the cutting fluid under different shapes, sizes or cutting conditions of the substrate, and improves the cooling and lubrication effect to a certain extent. For example, if the size of the substrate is smaller than the spacing between the two fixed nozzles 7, the substrate is fixed at a position close to the alignment of the mobile nozzle 26 and the fixed nozzle 7 by adjusting the mobile nozzle 26 to be close to one of the fixed nozzles 7, so that the dual nozzles can be used for cooling and lubrication when the substrate is processed; similarly, for processing conditions with strict requirements for cooling and lubrication, the requirements can be met by adjusting the position of the mobile nozzle 26.

[0028] Reference Figure 2 In order to save cutting fluid, in other embodiments, valves can be installed on both the fixed nozzle 7 and the movable nozzle 26, so that the valves can be operated to open or close the fixed nozzle 7 and the movable nozzle 26 as needed.

[0029] Reference Figure 3 and Figure 4In order to facilitate the adjustment of the blocking plate 9 to drive the movable nozzle 26 to slide, a matching hole 22 is provided on the top wall of the liquid storage chamber 5, and the matching hole 22 corresponds to the adjustment hole 8 one by one, and the matching hole 22 is aligned with the adjustment hole 8. The adjusting member includes an adjusting plate 10 and a transmission rod 12. The adjusting plate 10 is slidably arranged on the top wall of the liquid storage chamber 5. The sliding direction of the adjusting plate 10 is parallel to the arrangement direction of the multiple fixed nozzles 7. The adjusting plate 10 corresponds to the adjustment hole 8 one by one. The adjusting plate 10 is used to close the corresponding matching hole 22 to achieve the sealing of the liquid storage chamber 5. Slide blocks (not shown in the figure) are fixed at both ends of the adjusting plate 10. A slide groove (not shown in the figure) that slidably cooperates with the slide block is provided on the top wall of the liquid storage chamber 5. The slide block and the slide groove are cooperated to guide the sliding of the adjusting plate 10; an operating column 14 is fixed on the top of the adjusting plate 10, and the operating column 14 extends out of the corresponding matching hole 22, and the operating column 14 is aligned with the corresponding movable nozzle 26. The transmission rod 12 is fixed on one side of the adjustment plate 10 close to the corresponding sealing plate 9, and each adjustment plate 10 corresponds to two transmission rods 12. The mobile nozzle 26 is located between the two corresponding transmission rods 12, and the sealing plate 9 is connected to one end of the corresponding transmission rod 12 away from the adjustment plate 10.

[0030] Reference Figure 3 and Figure 4 Specifically, an adjusting rod 13 is fixed on the blocking plate 9, and the adjusting rod 13 corresponds one-to-one with the transmission rod 12 on the corresponding adjusting plate 10. The adjusting rod 13 is slidably connected with the corresponding transmission rod 12 along the vertical direction, and a sliding component is provided on the operating column 14 for enabling the adjusting rod 13 to drive the blocking plate 9 to slide toward or away from the adjusting plate 10.

[0031] Reference Figure 3 and Figure 4In order to facilitate the adjustment rod 13 to drive the blocking plate 9 to slide toward or away from the adjustment plate 10, a sliding cavity 23 is opened in the operating column 14. The sliding assembly includes a sliding block 15, a pressing block 16, a connecting rope 17 and an elastic pusher. The sliding block 15 is slidably arranged in the sliding cavity 23. The sliding direction of the sliding block 15 is parallel to the sliding direction of the adjustment rod 13. The pressing block 16 is slidably penetrated on the operating column 14. The sliding direction of the pressing block 16 is perpendicular to the sliding direction of the sliding block 15. Limiting blocks 24 are fixed on opposite sides of the pressing block 16. The limiting blocks 24 are located in the sliding cavity 23. Through the limiting blocks 24 The setting prevents the pressing block 16 from detaching from the operating column 14; the pressing block 16 is located below the sliding block 15, and the side of the sliding block 15 close to the pressing block 16 is an inclined surface, and the end of the inclined surface close to the sealing plate 9 is inclined toward the direction away from the pressing block 16, that is, the distance from the inclined surface to the inner wall of the sliding cavity 23 on the side away from the pressing block 16 decreases along the direction close to the sealing plate 9; the pressing block 16 is used to slide and abut against the inclined surface of the sliding block 15, and the side of the pressing block 16 close to the inclined surface is an arc surface, which convexes toward the direction close to the inclined surface. The setting of the arc surface facilitates relative sliding with the inclined surface of the sliding block 15 to push the sliding block 15 to move upward.

[0032] Reference Figure 3 and Figure 4 The connecting rope 17 corresponds to the adjusting rod 13 one by one, one end of the connecting rope 17 slides through the adjusting plate 10 and the operating column 14 and is fixedly connected to the sliding block 15, and the other end is fixed on the corresponding adjusting rod 13, wherein the connecting rope 17 is in a tensioned state, and the elastic pushing member is arranged on the adjusting plate 10, and the elastic pushing member is used to push the adjusting rod 13 to slide in a direction away from the adjusting plate 10.

[0033] Reference Figure 3 and Figure 4 In order to facilitate the adjustment rod 13 to slide in the direction away from the adjustment plate 10, the elastic pushing member includes a spring 18. The spring 18 corresponds to the transmission rod 12 one by one. The spring 18 is movably mounted on the corresponding transmission rod 12. One end of the spring 18 is fixedly set on the adjustment plate 10, and the other end is fixedly set on the adjustment rod 13. The spring 18 is always in a compressed state.

[0034] When the position of the mobile nozzle 26 needs to be adjusted, the user pinches the pressing block 16 with his fingers and pushes the pressing block 16 to slide in the direction close to the operating column 14. Then the pressing block 16 abuts against the inclined surface of the sliding block 15 and pushes the sliding block 15 to move upward. Since the connecting rope 17 is in a tensioned state, the sliding block 15 pulls the adjusting rod 13 through the connecting rope 17, so that the adjusting rod 13 drives the sealing plate 9 to slide a certain distance in the direction close to the adjusting plate 10, so that the sealing plate 9 is separated from the bottom wall of the liquid storage chamber 5, and the spring 18 is further compressed. At this time, the operating column 14 is moved while keeping the pressing block 16 pinched, so as to adjust the position of the mobile nozzle 26. When the movable nozzle 26 slides to the desired position, the pressing block 16 is released. At this time, the pulling force of the sliding block 15 on the connecting rope 17 is reduced, and the compressed spring 18 pushes the adjusting rod 13 to drive the sealing plate 9 to slide in the direction away from the adjusting plate 10. The connecting rope 17 pulls the sliding block 15 downward, and the inclined surface of the sliding block 15 abuts against the pressing block 16, so that the pressing block 16 is reset away from the operating column 14. Then, under the action of the spring 18, the sealing plate 9 is tightly abutted against the bottom wall of the liquid storage chamber 5, thereby blocking the corresponding adjusting hole 8, so that the cutting fluid will not leak, and under the friction between the sealing plate 9 and the bottom wall of the liquid storage chamber 5, the sealing plate 9 is not easy to slide.

[0035] Reference Figure 3 and Figure 4 In order to improve the sealing performance between the blocking plate 9 and the bottom wall of the liquid storage chamber 5, a sealing ring (not shown in the figure) is fixed on one side of the blocking plate 9 close to the adjustment hole 8, and the sealing ring is arranged along the circumference of the blocking plate 9. The sealing ring is in close contact with the bottom wall of the liquid storage chamber 5, on the one hand, it is further ensured that the cutting fluid will not leak, and on the other hand, the friction between the blocking plate 9 and the bottom wall of the liquid storage chamber 5 is enhanced to ensure that the blocking plate 9 will not slide under the contact of the spring 18.

[0036] Reference Figure 1 and Figure 3 , the mobile nozzle 26 is located outside the straight line formed by the multiple fixed nozzles 7, specifically, the mobile nozzle 26 is located on the side of the straight line formed by the multiple fixed nozzles 7 close to the workbench; so that the length of the adjustment hole 8 can be designed as long as possible according to needs, the moving range of the mobile nozzle 26 is expanded, and the blocking plate 9 will not block the fixed nozzle 7. At the same time, for substrates with complex shapes, the mobile nozzle 26 and the fixed nozzle 7 located at different positions in front and behind can ensure that the spraying range of the cutting fluid covers the substrate.

[0037] Reference Figure 3 and Figure 4A cleaning brush 19 is fixed on one side of the sealing plate 9 close to the adjusting plate 10 in the vertical direction. Two cleaning brushes 19 are provided on each sealing plate 9 and are located at both ends of the sealing plate 9. The bristles of the cleaning brush 19 abut against the bottom wall of the liquid storage chamber 5. The cleaning brush 19 has long bristles. The length direction of the cleaning brush 19 is perpendicular to the length direction of the sealing plate 9. The length of the cleaning brush 19 is greater than the length from the fixed nozzle 7 to the movable nozzle 26 in the width direction of the tool holder pad 3.

[0038] Because the bristles of the cleaning brush 19 are relatively long, and during the movement of the adjustment plate 10, the gap between the sealing plate 9 and the bottom wall of the liquid storage chamber 5 is very small, the bristles of the cleaning brush 19 are still in contact with the bottom wall of the liquid storage chamber 5; as the sealing plate 9 moves horizontally, the cleaning brush 19 cleans the bottom wall of the liquid storage chamber 5, which helps to remove dirt on the bottom wall of the liquid storage chamber 5.

[0039] Reference Figure 1 and Figure 5 Specifically, each scraper 4 includes a mounting portion 41 and a scraping blade portion 42. The mounting portion 41 is rectangular and fixedly mounted on the lower surface of the mounting seat 21. The scraping blade portion 42 is integrally formed on the side of the mounting portion 41 close to the workbench. The longitudinal section of the scraping blade portion 42 is a right triangle. The fixed nozzle 7 and the movable nozzle 26 are both aligned with the mounting portion 41 of the corresponding scraper 4. The mounting portion 41 is provided with a through hole 25, which passes through the mounting portion 41 and is staggered with the fixed nozzle 7. The through hole 25 is provided so that part of the cutting fluid flowing to the mounting portion 41 of the scraper 4 can flow downward along the through hole 25, thereby ensuring cooling and lubrication between the bottom of the scraper 4 and the substrate during the processing. A filter membrane 20 is fixedly provided on one side of the through hole 25 close to the blade seat pad 3. The filter membrane 20 is provided so that impurities are not easy to enter the through hole 25, thereby avoiding affecting the scraping blade between the bottom of the scraper 4 and the substrate.

[0040] The implementation principle of the embodiment of the present application is: when in use, fix the substrate on the workbench, then pinch the pressing block 16 with your fingers, and push the pressing block 16 to slide in the direction close to the operating column 14, then the pressing block 16 abuts against the inclined surface of the sliding block 15 and pushes the sliding block 15 to move up, at this time the sliding block 15 pulls the adjusting rod 13 through the connecting rope 17, so that the adjusting rod 13 drives the sealing plate 9 to slide a certain distance in the direction close to the adjusting plate 10, so that the sealing ring on the sealing plate 9 is separated from the bottom wall of the liquid storage chamber 5, at this time, keep pinching the pressing block 16 to move the operating column 14, and adjust the movable nozzle 26 to the desired position according to the shape, size or cutting conditions of the workpiece.

[0041] Then release the pressing block 16. At this time, the pulling force of the sliding block 15 on the connecting rope 17 is reduced, and the compressed spring 18 pushes the adjusting rod 13 to drive the sealing plate 9 to reset in the direction away from the adjusting plate 10. The connecting rope 17 pulls the sliding block 15 downward, and the inclined surface of the sliding block 15 abuts the pressing block 16 away from the operating column 14 for reset. Under the action of the spring 18, the sealing ring of the sealing plate 9 is tightly abutted against the bottom wall of the liquid storage chamber 5. Under the friction force between the sealing plate 9 and the bottom wall of the liquid storage chamber 5, the sealing plate 9 and the knife seat pad 3 are relatively fixed.

[0042] Then the cutting fluid is introduced into the liquid storage chamber 5, and the cutting fluid flows from the movable nozzle 26 and the fixed nozzle 7 to the mounting portion 41 of the scraper 4. The mutual cooperation between the movable nozzle 26 and the fixed nozzle 7 helps to ensure the coverage of the cutting fluid under different shapes, sizes or cutting conditions, and improves the cooling and lubrication effect to a certain extent.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
