Description

Technical Field

[0001] The utility model relates to the technical field of valve casting and processing, and specifically relates to a casting device for valve castings. Background Technique

[0002] Casting is a method of pouring liquid metal into a casting cavity adapted to the shape of a part and waiting for it to cool and solidify to obtain the part or blank. When processing thick and large valves, they are often processed by casting;

[0003] After casting thick and large valves, burrs sometimes remain on the surface. The existing deburring methods for thick and large valves mostly remove burrs manually. When deburring, the thick and large valves are first clamped and fixed, and then the operator manually holds a grinding machine to grind the surface of the thick and large valves. However, such a deburring method has two problems. First, when clamping thick and large valves, it is inconvenient to quickly clamp and fix valves with different diameter sizes. Second, manual grinding and deburring can only grind the surface of the valve locally, and it is inconvenient to simultaneously grind and deburr different positions on the valve surface, thus reducing the efficiency of casting and processing thick and large valves.

[0024] Please refer to Figures 1-5 , the present utility model provides a casting device for a valve casting, including a processing outer cylinder 1, the top end of the processing outer cylinder 1 is threadedly connected with a top cover 2, the bottom surface of the processing outer cylinder 1 is installed with a first motor 3, the output end of the first motor 3 is fixed with a double-group turntable 4, inner rotation grooves 5 and outer rotation grooves 6 are opened on the inner and outer side surfaces of the double-group turntable 4, inner sliding pins 7 and outer sliding pins 8 slide inside the inner rotation grooves 5 and the outer rotation grooves 6, inner sliding grooves 9 and outer sliding grooves 10 are opened on the inner and outer sides of the bottom surface of the processing outer cylinder 1, inner clamping sliding rods 11 and outer clamping sliding rods 12 slide inside the inner sliding grooves 9 and the outer sliding grooves 10, a stepped base 13 is fixed on the inner bottom surface of the processing outer cylinder 1, and a thick and large valve body 14 is placed on the stepped base 13;

[0025] On the inner wall of the processing outer cylinder 1, a guide rail 15 is installed. A guide groove 16 is provided inside the guide rail 15. A second motor 17 is installed on the inner top surface and bottom surface of the guide groove 16. A threaded rod 18 is fixed to the output end of the second motor 17. A slider 19 slides inside the guide groove 16. A side fixing block 20 is fixed to the side surface of the slider 19. A third motor 21 is installed between the two groups of side fixing blocks 20. A universal joint 22 is fixed to the output end of the third motor 21. An arc-shaped shaft 23 is fixed between the two universal joints 22. A steel brush 24 is installed on the inner side of the outer surface of the arc-shaped shaft 23. By placing the thick large valve body 14 on the ladder pedestal 13 and then covering the top cover 2 to prevent debris from flying out when deburring the surface of the thick large valve body 14, and the thick large valve body 14 can be quickly clamped and fixed by the inner clamping slide rod 11 and the outer clamping slide rod 12.

[0026] Further, one side of the universal joint 22 is rotatably connected to the side fixing block 20. Both ends of the arc-shaped shaft 23 are rotatably connected to the side fixing block 20 through the universal joint 22. A plurality of groups of steel brushes 24 are arranged along the circumferential direction of the arc-shaped shaft 23. The universal joint 22 enables the arc-shaped shaft 23 to drive the steel brush 24 on its surface to swing reciprocally, so as to adjust the distance between the steel brush 24 and the thick large valve body 14 according to the different sizes of the thick large valve body 14. At the same time, the arc-shaped shaft 23 can also drive the steel brush 24 to move reciprocally in the up and down directions, so as to deburr different positions on the surface of the thick large valve body 14.

[0027] Further, the threaded rod 18 passes through the slider 19 and is threadedly connected thereto. The side fixing block 20 is slidably connected to the guide rail 15 in the up and down direction through the guide groove 16 and the slider 19. By rotating the threaded rod 18 forward or backward, the slider 19 can be driven to move in the up and down direction. Further, the slider 19 can drive the arc-shaped shaft 23 to drive the steel brush 24 to move in the up and down direction through the side fixing block 20 and the universal joint 22.

[0028] Further, the top end of the inner sliding pin 7 is fixedly connected to the inner clamping slide rod 11, and the top end of the outer sliding pin 8 is fixedly connected to the outer clamping slide rod 12. The thick large valve body 14 is located between the inner clamping slide rod 11 and the outer clamping slide rod 12. When the inner sliding pin 7 moves, the inner clamping slide rod 11 can be driven to move. When the outer sliding pin 8 moves, the outer clamping slide rod 12 can be driven to move. Thus, the thick large valve body 14 can be clamped and fixed by the inner clamping slide rod 11 moving outward and the outer clamping slide rod 12 moving inward. Similarly, when the inner clamping slide rod 11 moves inward and the outer clamping slide rod 12 moves outward, the thick large valve body 14 is no longer clamped and fixed.

[0029] Further, the inner rotating groove 5 and the outer rotating groove 6 are not concentric with the double groups of turntables 4, and the arc directions of the inner rotating groove 5 and the outer rotating groove 6 are opposite, as shown in the attached instruction manual Figure 1 and the attached instruction manual Figure 3As shown in the figure, when the double-group turntable 4 rotates clockwise, the inner sliding pin 7 can be driven to move outward through the inner rotating groove 5. At this time, the inner clamping slide bar 11 can guide the inner sliding pin 7 in the horizontal direction. Through the outer rotating groove 6, the outer sliding pin 8 can be driven to move inward. At this time, the outer clamping slide bar 12 can guide the outer sliding pin 8 in the horizontal direction. Similarly, when the double-group turntable 4 rotates counterclockwise, the inner sliding pin 7 moves inward and the outer sliding pin 8 moves outward.

[0030] Furthermore, the stepped base 13 is in the shape of a double-step platform. The inner clamping slide bar 11 is slidably connected to the upper stepped platform, and the outer clamping slide bar 12 is slidably connected to the lower stepped platform. By horizontally moving the inner clamping slide bar 11 outward on the upper stepped platform and horizontally moving the outer clamping slide bar 12 inward on the lower stepped platform, the thick large valve body 14 can be firmly clamped and fixed from both the inside and the outside through the inner clamping slide bar 11 and the outer clamping slide bar 12.

[0031] During use, the thick large valve body 14 is placed on the stepped base 13, and then the top cover 2 is covered to prevent debris from flying out when deburring the surface of the thick large valve body 14. After the thick large valve body 14 is stably placed on the stepped base 13, the first motor 3 is started to drive the double-group turntable 4 to rotate. Further, the double-group turntable 4 can drive the inner sliding pin 7 to move outward through the inner rotating groove 5, and the inner sliding pin 7 drives the inner clamping slide bar 11 to move horizontally outward inside the inner sliding groove 9. Thus, the thick large valve body 14 can be quickly clamped and fixed from the inside through the inner clamping slide bar 11. Similarly, when the double-group turntable 4 rotates, the outer sliding pin 8 can be driven to move inward through the outer rotating groove 6, and the outer sliding pin 8 drives the outer clamping slide bar 12 to move horizontally inward inside the outer sliding groove 10. Thus, the thick large valve body 14 can be quickly clamped and fixed from the outside through the outer clamping slide bar 12. Therefore, thick large valve bodies 14 with different diameter sizes can be quickly clamped and fixed. After the thick large valve body 14 is clamped and fixed, the third motor 21 is first started to drive the universal joint 22 to rotate forward and backward reciprocally. Further, the universal joint 22 drives the steel brush 24 to swing through the arc-shaped shaft 23, so as to adjust the distance between the steel brush 24 and the thick large valve body 14 according to the different sizes of the thick large valve body 14 and scrape and deburr the surface of the thick large valve body 14. During the process of the arc-shaped shaft 23 driving the steel brush 24 to swing reciprocally, the second motor 17 is started to drive the threaded rod 18 to rotate reciprocally. Further, the threaded rod 18 can drive the slider 19 to move reciprocally in the up and down direction, and the slider 19 can make the arc-shaped shaft 23 drive the steel brush 24 to also move reciprocally in the up and down direction through the side fixing block 20 and the universal joint 22. Thus, different positions on the surface of the thick large valve body 14 can be scraped and deburred.

[0032] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
