Description

Technical Field

[0001] This utility model relates to the field of ceramic core processing technology, and in particular to a tooling for grinding ceramic cores. Background Technology

[0002] Ceramic cores are specialized ceramic components used in investment casting to form the internal cavity structure of castings. They work in conjunction with the outer mold and shell to ensure dimensional accuracy of the cavity, making them particularly suitable for precision casting of complex structures such as turbine blades for aero-engines. During the machining process, the surface of the formed ceramic core has burrs. To ensure quality, workers need to grind the surface of the ceramic core. This grinding dust is released into the air, affecting air quality and worker health.

[0003] The existing tooling for grinding ceramic cores does not have an effective dust suppression device during use. When grinding ceramic cores, a certain amount of dust is generated. The lack of effective dust suppression will cause the dust to be scattered into the air, which will seriously affect the health of the workers. Utility Model Content

[0017] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Example 1 A tooling for grinding ceramic cores, such as Figure 1-4 As shown, the dust suppression system includes a dust suppression spray assembly, which includes a grinding chamber 1. A conveying pump 19 is installed on the top of the grinding chamber 1, and a connector is installed on the top of the conveying pump 19. A connecting flange 18 is installed at one end of the connector. A spray frame 2 is installed on one side of the grinding chamber 1 and is connected to the conveying pump 19. A water collection frame 5 is installed on one side of the grinding chamber 1. The opening of the water collection frame 5 gradually expands from bottom to top, and the position of the water collection frame 5 is adapted to the spray frame 2. A collection chamber 9 is installed at the bottom of the grinding chamber 1 and is connected to the water collection frame 5. A grinding component for grinding and a fixing component for positioning are installed on one side of the grinding chamber 1, and a collection component for water collection is installed on one side of the collection chamber 9. In use, the ceramic core can be fixed by the fixing component, and the fixed ceramic core can be ground by the grinding component. Grinding can effectively remove burrs and impurities from its surface. During the grinding process, a water supply pipe can be connected through the connector of the delivery pump 19, and the connection can be reinforced by the connecting flange 18. The delivery pump 19 can be started to deliver water to the spray frame 2, and the water is sprayed out through several sets of nozzles at the bottom of the spray frame 2. The water sprayed out by the spray frame 2 can spray the ceramic core being ground. The water spray can also act as a lubricant during the grinding process, effectively reducing wear. This design increases the service life of the ceramic core while reducing dust, preventing dust from splashing during grinding and affecting the health of workers. The water spray during grinding also has a cooling effect, preventing deformation of the ceramic core due to frictional heat and stress concentration. The wastewater from dust reduction slides down into the water collection rack 5 for collection. The large opening of the water collection rack 5 prevents leakage. The wastewater carries dust and other impurities from the water collection rack 5 into the collection chamber 9 for collection by the collection components, thus effectively reducing the difficulty of cleaning. The fixing component includes a cylinder 3, which is installed on the inner wall of one side of the grinding chamber 1. A fixing seat 17 is provided at the end of the cylinder 3. A rotary motor 24 is provided on one side of the fixing seat 17. A rotating frame 16 is connected to the output end of one side of the rotary motor 24. A threaded rod 4 is rotatably installed at one end of the fixing seat 17. A positioning seat 25 is provided at the end of the threaded rod 4. One end of the threaded rod 4 is rotatably connected to the positioning seat 25. A rotating seat is rotatably installed on one side of the positioning seat 25. The position of the rotating seat is adapted to the rotating frame 16. Two sets of guide holes are opened on one side of the fixing seat 17. A guide rod can be slidably installed through the guide holes. One end of the guide rod is fixed to the positioning seat 25. In use, the rotating frame 16 is made of rubber. Several sets of rubber anti-slip protrusions are provided on one side of the rotating seat. During grinding, the ceramic core can be moved between the rotating frame 16 and the positioning seat 25. The positioning seat 25 can be moved by rotating the threaded rod 4, thereby adjusting the distance between the rotating seat and the rotating frame 16 to clamp and fix the ceramic core. After clamping and fixing, it can be effectively positioned to prevent displacement during grinding. The guide rod sliding in the guide hole can prevent the positioning seat 25 from shifting during movement. After positioning, the rotating frame 16 can be rotated by starting the rotary motor 24, thereby synchronously controlling the rotation of the fixed ceramic core. By controlling its rotation, it is convenient to perform comprehensive grinding. The rubber rotating frame 16, together with the anti-slip protrusions on the rotating seat, can play a protective and anti-slip role during clamping and fixing. The grinding assembly includes a hydraulic cylinder 14, which is installed on the inner wall of one side of the grinding chamber 1. A mounting base 13 is provided at the end of the hydraulic cylinder 14. A speed-regulating motor 23 is provided on one side of the mounting base 13. A transmission shaft 12 is connected to the output end of the speed-regulating motor 23. One end of the transmission shaft 12 is rotatably installed through the mounting base 13. A grinding wheel 15 is provided on the transmission shaft 12. When in use, the position of the grinding wheel 15 is matched with the fixed seat 17. The speed-regulating motor 23 can start to control the rotation of the transmission shaft 12 and the grinding wheel 15. The hydraulic cylinder 14 can control the rotating grinding wheel 15 to move and contact the ceramic core fixed on the rotating frame 16. The rotating grinding wheel 15 can grind the ceramic core to remove burrs and impurities. The collection component includes a collection box 8, with first sliders 10 symmetrically arranged on both sides of the collection box 8. Slide grooves are symmetrically opened on the inner walls of both sides of the collection chamber 9. The size and position of the first sliders 10 are adapted to the slide grooves. A transparent observation window is provided on one side of the collection box 8. When in use, wastewater containing dust, debris and impurities can flow into the collection box 8 through the water collection rack 5 for collection. The amount of water in the collection box 8 can be observed through the transparent observation window. When the amount of water is large, the collection box 8 can be pulled out for cleaning. Collecting wastewater through the collection box 8 can effectively reduce the difficulty of cleaning and facilitate the recycling of wastewater. For filtering, such as Figure 2 , 3 As shown in Figure 4, support blocks are symmetrically arranged on the inner walls of both sides of the water collection frame 5, and a filter screen 20 is provided on one side of the support block. The size of the filter screen 20 is adapted to the water collection frame 5. When in use, wastewater flows into the collection box 8 through the water collection rack 5 and is filtered by the filter screen 20 installed in the water collection rack 5, thereby removing large particles of impurities and facilitating subsequent wastewater recycling. After a certain period of use, the filter screen 20 can be removed for cleaning. In order to purify wastewater, such as Figure 1 , 3 As shown in Figure 4, an opening is provided on one side of the water collection frame 5, and an installation groove is provided on the inner wall of the opening.
