DETAILED DESCRIPTION

[0025] The following combination Figure 1-Figure 5 This application is described in further detail.

[0026] The embodiment of the present application discloses a gantry skiving 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 mounted on the gantry 1 in the vertical direction. The driving method of the fixed plate 2 is conventional and will not be elaborated here. A toolholder pad 3 and a mounting seat 21 are fixedly mounted on the fixed plate 2. The toolholder pad 3 is located above the mounting seat 21. The horizontal distance from the side of the toolholder 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, so that the side of the toolholder pad 3 close to the workbench extends out of the mounting seat 21. A scraper 4 is fixedly mounted on the lower surface of the mounting seat 21 so that the toolholder pad 3 is located above the scraper 4. In order to save costs and to simultaneously meet the needs of scraping multiple substrates, a plurality of scrapers 4 are spaced apart along the length direction of the toolholder pad 3. Specifically, two scrapers 4 are provided on the mounting seat 21.

[0027] Reference Figure 2 and Figure 3 A liquid storage chamber 5 is provided in the toolholder pad 3. The liquid storage chamber 5 is located on the side of the toolholder pad 3 close to the workbench, so that the liquid storage chamber 5 is offset from the mounting hole on the toolholder pad 3. A liquid inlet pipe 6 is provided on the toolholder pad 3, which is connected to the liquid storage chamber 5. The liquid inlet pipe 6 is used to connect to an external cutting fluid source to facilitate the introduction of cutting fluid into the liquid storage chamber 5. A plurality of fixed nozzles 7 are fixedly mounted on the side of the toolholder pad 3 close to the scraper 4. 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 to the liquid storage chamber 5. The fixed nozzles 7 are located on the side of the mounting base 21 close to the workbench. The fixed nozzles 7 are aligned with the upper end of the scraper 4 to facilitate the flow of cutting fluid onto the scraper 4. In the embodiment of the present application, each scraper 4 corresponds to two fixed nozzles 7. The two fixed nozzles 7 corresponding to each scraper 4 are located at both ends of the scraper 4 to facilitate cooling and lubricating the scraper 4.

[0028] Reference Figure 2 and Figure 3, an adjusting hole 8 is opened on the 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, and the length direction of the adjusting hole 8 is parallel to the arrangement direction of the multiple fixed nozzles 7, and 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, and the sealing plate 9 is used to close the corresponding adjusting hole 8. The cross-section of the sealing plate 9 is rectangular, and 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, and a movable nozzle 26 is pierced on the sealing plate 9. The movable nozzle 26 extends outside the corresponding adjusting hole 8 and is connected to the liquid storage chamber 5. The knife seat pad 3 is provided with an adjusting member for adjusting the sealing plate 9 to drive the movable nozzle 26 to slide.

[0029] During use, the sealing plate 9 is adjusted to slide along the corresponding adjustment hole 8 through the adjustment member. The movable nozzle 26 is adjusted to the desired position according to the shape, size, or cutting conditions of the substrate. The interaction between the movable nozzle 26 and the fixed nozzle 7 helps to ensure the coverage of the cutting fluid under different substrate shapes, sizes, or cutting conditions, 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, by adjusting the movable nozzle 26 to be closer to one of the fixed nozzles 7, the substrate can be fixed in a position close to the alignment of the movable nozzle 26 and the fixed nozzle 7, thereby achieving dual nozzle cooling and lubrication during substrate processing. Similarly, for processing conditions with strict cooling and lubrication requirements, adjusting the position of the movable nozzle 26 can meet the requirements.

[0030] 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.

[0031] Reference Figure 3 and Figure 4In order to facilitate the adjustment of the sealing 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-to-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-to-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, and a slide groove (not shown in the figure) is provided on the top wall of the liquid storage chamber 5 to slide with the slider. The slide is guided by the cooperation of the slider and the slide groove; 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 the 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 corresponding two transmission rods 12, and the sealing plate 9 is connected to the end of the corresponding transmission rod 12 away from the adjustment plate 10.

[0032] 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 to 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 causing the adjusting rod 13 to drive the blocking plate 9 to slide toward or away from the adjusting plate 10.

[0033] 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 a slope, and the end of the slope close to the sealing plate 9 is inclined toward the direction away from the pressing block 16, that is, the distance from the slope 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 slope of the sliding block 15, and the side of the pressing block 16 close to the slope is an arc surface, which convexes outward in the direction close to the slope. The setting of the arc surface facilitates relative sliding with the slope of the sliding block 15 to push the sliding block 15 to move upward.

[0034] 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 provided 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.

[0035] Reference Figure 3 and Figure 4 In order to facilitate the sliding of the adjusting rod 13 in the direction away from the adjusting 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 sleeved on the corresponding transmission rod 12. One end of the spring 18 is fixed on the adjusting plate 10, and the other end is fixed on the adjusting rod 13. The spring 18 is always in a compressed state.

[0036] 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 toward 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 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 toward 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, keep pinching the pressing block 16 and move the operating column 14 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 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.

[0037] Reference Figure 3 and Figure 4 To improve the seal between the sealing plate 9 and the bottom wall of the liquid storage chamber 5, a sealing ring (not shown) is fixed to the side of the sealing plate 9 near the adjustment hole 8. The sealing ring is arranged along the circumference of the sealing plate 9. The tight contact between the sealing ring and the bottom wall of the liquid storage chamber 5 not only further prevents the cutting fluid from leaking, but also enhances the friction between the sealing plate 9 and the bottom wall of the liquid storage chamber 5, ensuring that the sealing plate 9 does not slip under the contact of the spring 18.

[0038] Reference Figure 1 and Figure 3 The movable nozzle 26 is located outside the straight line formed by the multiple fixed nozzles 7. Specifically, the movable nozzle 26 is located on the side of the straight line formed by the multiple fixed nozzles 7 close to the workbench. This allows the length of the adjustment hole 8 to be designed as long as necessary, expanding the movable range of the movable nozzle 26, and the blocking plate 9 will not block the fixed nozzle 7. At the same time, for substrates with complex shapes, the movable nozzle 26 and the fixed nozzle 7 located at different front and rear positions can ensure that the cutting fluid spray range covers the substrate.

[0039] Reference Figure 3 and Figure 4A cleaning brush 19 is fixed in the vertical direction on one side of the sealing plate 9 close to the adjusting plate 10. 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 are in contact with 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.

[0040] Since the bristles of the cleaning brush 19 are long, and the gap between the sealing plate 9 and the bottom wall of the liquid storage chamber 5 is very small during the movement of the adjustment plate 10, 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.

[0041] 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 cross-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. A through hole 25 is provided on the mounting portion 41, which passes through the mounting portion 41 and is staggered from the fixed nozzle 7. The provision of the through hole 25 allows some of the cutting fluid flowing to the mounting portion 41 of the scraper 4 to flow downward along the through hole 25, thereby ensuring cooling and lubrication between the bottom of the scraper 4 and the substrate during the machining process. A filter membrane 20 is fixedly mounted on the side of the through hole 25 close to the blade seat pad 3. The provision of the filter membrane 20 prevents impurities from entering the through hole 25, thereby avoiding affecting the scraping blade between the bottom of the scraper 4 and the substrate.

[0042] 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 toward 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 toward 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 and 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.

[0043] 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.

[0044] 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. Through the mutual cooperation between the movable nozzle 26 and the fixed nozzle 7, it helps to ensure the coverage of the cutting fluid under different shapes, sizes or cutting conditions, and improve the cooling and lubrication effect to a certain extent.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
