Description
Technical Field
[0001] This invention relates to the technical field of drill-type air-blowing hole equipment, specifically a three-axis dual-station sand-cleaning device for air-blowing holes that retains residual sand in sand drill holes. Background Technology
[0002] A sand mold is a casting cavity made of raw sand, binder, and other materials in casting production. It belongs to the field of material forming and is mainly used in sand casting processes, including both manual and mechanical molding methods. Its structure consists of an upper sand mold and a lower sand mold, with the parting surface being the contact surface between the upper and lower sand molds. The cavity is formed by removing the pattern, and a core is installed inside to create the casting holes. It is equipped with a gating system and vents. Sand casting has a short production cycle, low product cost, and no restrictions on product batch size, making it a fundamental process in casting production. With technological advancements, the core sand materials used in sand casting have also continuously improved. Self-hardening resin sand can harden and solidify at room temperature through the action of a catalyst. Due to its high strength, ease of molding, and high core dimensional accuracy, it is now widely used in casting production. After drilling holes in the sand mold with a venting machine, residual sand remains in the vent holes, requiring thorough cleaning to ensure all vent holes are unobstructed. Manual sand blowing is time-consuming, labor-intensive, and prone to leaving residue.
[0003] This case arose in order to resolve the aforementioned issues. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a three-axis dual-station sand cleaning device for removing residual sand from sand drill holes, thus solving the problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a three-axis dual-station sand cleaning device for removing residual sand from sand drill holes, comprising a worktable with two placement areas. A Z-axis frame, a Y-axis frame, and an X-axis frame are sequentially arranged around the placement areas on the worktable. A Y-axis frame is fixedly mounted on the Z-axis frame.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0016] like Figure 1-7 The device, as shown, is a three-axis, dual-station sand-cleaning device for removing residual sand from sand drill holes. It includes a worktable 1 with two placement areas 2. Sand molds are placed in placement areas 2. After drilling holes in the sand molds using a sand-drilling machine, the molds are transported to a turning machine to flip them so that the drilled surface faces upwards and they are placed in placement areas 2. An automatic air-blowing device cleans the residual sand from the vent holes. Around placement areas 2, the worktable 1 is arranged in sequence with a Z-axis guide frame 3, a Y-axis guide frame 4, and an X-axis guide frame 6. The Y-axis guide frame 4 is fixed to the Z-axis guide frame 3, and a Y-axis guide frame sliding block 5 is slidably connected to the Y-axis guide frame 4. The X-axis guide frame 6 is fixed to the Y-axis guide frame sliding block 5. X-axis truss 6 is slidably connected to X-truss sliding block 16, which has a fixed structure. The XYZ three-axis modules all use servo modules. One module can complete the cleaning of one vent hole in 1 to 2 seconds. Air blowing pipe 8 is fixed on connecting block 9. Air blowing nozzle is provided at the lower end of air blowing pipe 8. The air blowing nozzle can be inserted into the vent hole for air blowing cleaning when necessary. The twist drill used for sand mold vent hole is φ20mm. The other end of air blowing pipe 8 is connected to venting component. Air source two-piece set such as air filter and pressure reducing valve should be equipped in front of air blowing nozzle to ensure that the air blown into sand mold is dry and the air pressure is stable.
[0017] The X-axis truss 6 is provided with a horizontal column 7, and the X-truss sliding block 16 is slidably connected to the horizontal column 7. The length and width of the horizontal column 7 are greater than the width of the placement area 2. The fixing structure includes a connecting block connection 17, a limiting plate 18, a clip and plate 19, and an extension column 20. There are two limiting plates 18, and the two limiting plates 18 are fixed on the X-truss sliding block 16. A slot is vertically opened on the limiting plate 18, and the clip and plate 19 is slidably connected in the slot.
[0018] The working principle of the fixed structure is as follows: Press the clip and post 21 on the side wall of the connecting block connection 17 inward. At this time, the outer end of the clip and post 21 is flush with the first fixing plate 23. The second spring 25 retracts, and then the connecting block connection 17 is clipped into the X-shaped frame slider 16. When the extension post 20 contacts the clip and plate 19, the connecting block connection 17 continues to move inward. Since the part of the clip and plate 19 corresponding to the circular groove on the limiting plate 18 has a downward arc, as the connecting block connection 17 moves inward, the extension post 20 moves from abutting against the clip and plate 19 to continuing to move into the circular groove. At this time, the clip and plate 19 is lifted, and the extension post 20 extends into the circular groove on the limiting plate 18. The clip and plate 19 falls down, completing the limitation of the extension post 20. At this time, the clip and post 21 is located inside the X-shaped frame slider 16, directly opposite the slot on the clip groove 22. The second spring 25 then extends and pushes the clip and post 21 into the slot to further achieve limitation.
[0019] The limiting plate 18 has a circular groove, the size of which is the same as the diameter of the extension column 20, so that the extension column 20 fits perfectly into the circular groove and will not wobble up and down. The extension column 20 is fixed to the side wall of the connecting block connection 17. The two side walls of the connecting block connection 17 have holes, and the second fixing plate 26 is fixedly connected in the holes. The first fixing plate 23 is fixed at the opening of the holes. The X-shaped frame sliding block 16 has a locking groove 22 inside.
[0020] Both the first fixing plate 23 and the second fixing plate 26 are passed through by the clip and post 21, and the clip and post 21 are slidably connected to both. The clip and post 21 can be squeezed into the connection point 17 of the connecting block. A stop plate 24 is fixedly connected to the clip and post 21, and the stop plate 24 is located between the two fixing plates. One end of the second spring 25 is connected to one side wall of the stop plate 24, and the other end of the second spring 25 is fixed to the side wall of the second fixing plate 26. When the clip and post 21 is squeezed into the connection point 17 of the connecting block, the stop plate 24 moves synchronously with the clip and post 21 as it moves inward. The position of the second fixing plate 26 remains unchanged, so the second spring 25 will be squeezed and contracted. When the end of the clip and post 21 is aligned with the slot, the second spring 25 relaxes and pushes it out.
[0021] The inner sides of the two clips and slots 22 are provided with slots and holes. The size of the clips and posts 21 is the same as the size of the slots and holes of the clips and slots 22, so that the clips and posts 21 can be inserted into the clips and slots 22. The ends of the clips and posts 21 are made of elastic material. When the clips and plates 19 are lifted upwards and the connecting block connection 17 is pulled outwards, the ends of the clips and posts 21 can undergo slight deformation and be squeezed into the connecting block connection 17. The connecting block connection 17 can be pulled out, thereby completing the separation.
[0022] The connecting block connection 17 is fixedly connected to the connecting block 9. After the connecting block 9 is connected to the X-axis rafter slider 16, it can move on the X-axis rafter 6 so that the air nozzle is aligned with each air hole. The outer wall of the connecting block 9 is provided with a clip and structure to fix the position of the air tube 8. The clip and structure includes a clip and block 10, a grip block 11, a moving column 12, a first spring 13, and a fixing column 14. The inner wall of the grip block 11 is fixedly connected to the moving connecting column 15. The fixing column 14 is fixedly provided on the side wall of the clip and block 10 at the position corresponding to the grip 11.
[0023] The working principle of the card and block is as follows: Pull the two grips 11 on the card and block 10 outward, the movable connecting post 15 moves outward within the fixed post 14, causing the blocking plate to move towards the inner wall of the card and block 10, the first spring 13 contracts, at this time the air tube 8 is placed into the card and block 10, after the grips 11 are released, the first spring 13 relaxes, pushing the blocking plate outward, at this time the two blocking plates leave the card and block 10, the movable connecting post 15 moves forward, the two blocking plates at this time close the groove on the card and block 10 which is in the shape of a "U", at this time the air tube 8 is limited.
[0024] The fixed column 14 is hollow and extends into the side wall of the card and block 10. A movable connecting column 15 is slidably connected inside it. A first spring 13 is wrapped around the movable connecting column 15. One end of the first spring 13 is fixed to the end of the fixed column 14. A baffle plate is fixedly connected to the other end of the movable connecting column 15. There are two baffle plates, which are arranged in a mirror image. The two baffle plates are very close to each other in their natural state, which can fix and limit the air tube 8 located in the card and block 10.
[0025] The above-described embodiments are for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
