Technical Field

[0001] This utility model relates to the field of valve end cap processing technology, and in particular to a valve end cap processing equipment. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief.

[0021] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0022] according to Figure 1-6 As shown, a valve end cap processing equipment includes a worktable 1. The top of the worktable 1 is provided with a mounting groove 2, which extends to both the front and rear ends of the worktable 1. A positioning mechanism is movably installed in the mounting groove 2. The positioning mechanism includes a movable table 3. A clamping seat 4 is rotatably installed on the top of the movable table 3. A drive assembly for driving the clamping seat 4 to rotate is provided on the movable table 3. Several sets of clamping blocks 5 are movably installed on the top of the clamping seat 4. A drive seat 6 is movably installed inside the clamping seat 4. A wedge-shaped surface 62 is provided at the top of the drive seat 6. The clamping blocks 5 are fitted onto the wedge-shaped surface 62. A movable rod 8 is slidably installed at the bottom of the clamping seat 4. The movable rod 8 is rotatably connected to the drive seat 6. A first hydraulic cylinder 9 for driving the movable rod 8 to move is provided at the bottom of the movable table 3. A drilling mechanism is also provided on the worktable 1.

[0023] In this embodiment, the clamping seat 4 has an internal mounting cavity 41. A sliding groove 42 is formed on the side wall of the mounting cavity 41, extending along the axial direction of the clamping seat 4. A slider 61 matching the sliding groove 42 is fitted onto the side wall of the drive seat 6. Several sets of T-slots 63 are formed on the wedge-shaped surface 62, the number of which is equal to the number of clamping blocks 5. A T-block 51 matching the T-slot 63 is fixedly installed at the bottom end of each clamping block 5. Several sets of guide grooves 43 are formed on the top surface of the clamping seat 4. The grooves 43 are arranged in a circumferential array around the axis of the clamping seat 4. The clamping blocks 5 are slidably installed in the guide grooves 43. The guide grooves 43 are connected to the interior of the mounting cavity 41. The bottom end of the clamping blocks 5 extends through the guide grooves 43 into the mounting cavity 41. The T-shaped block 51 at the bottom end of the clamping blocks 5 is slidably installed in the T-shaped groove 63. When the first hydraulic cylinder 9 pulls the drive seat 6 downward, under the combined action of the T-shaped block 51 and the T-shaped groove 63, the clamping blocks 5 move closer to each other under the guidance of the guide grooves 43, thereby clamping the workpiece.

[0024] In this embodiment, a through hole 44 is provided at the top center of the clamping seat 4, and a top block 7 is provided inside the through hole 44. The top block 7 is fixedly installed on the top of the drive seat 6. When the first hydraulic cylinder 9 pushes the drive seat 6 upward, the clamping blocks 5 open outward to release the workpiece. When the clamping blocks 5 open to the limit position, the top block 7 protrudes from the top surface of the clamping seat 4, thereby lifting the workpiece upward so that the operator can remove the workpiece from the clamping seat 4.

[0025] In this embodiment, a base plate 10 is fixedly installed on the bottom of the moving platform 3 by bolts. The first hydraulic cylinder 9 is fixedly installed on the base plate 10 by a bracket. A connecting part 81 is fixedly connected to the bottom end of the movable rod 8. The cross-section of the connecting part 81 is a hexagonal structure. The connecting part 81 is slidably installed on the base plate 10. The output end of the first hydraulic cylinder 9 is fixedly connected to the connecting part 81. Under the joint action of the connecting part 81 and the base plate 10, the movable rod 8 is circumferentially limited to prevent the movable rod 8 from rotating when the clamping seat 4 rotates.

[0026] In this embodiment, the drive assembly includes a drive motor 11, which is fixedly mounted on the base plate 10 via a motor bracket. A first gear 12 is fixedly mounted on the output shaft of the drive motor 11, and a second gear 13 is fixedly mounted on the outer wall of the clamping seat 4. The second gear 13 meshes with the first gear 12. The drive motor 11 drives the first gear 12 to rotate, and the clamping seat 4 rotates under the cooperation of the first gear 12 and the second gear 13, thereby adjusting the angle of the workpiece to achieve circumferential drilling of the valve end cover.

[0027] In this embodiment, the drilling mechanism includes a fixed frame 14, which is fixedly installed at the top rear end of the workbench 1. A second hydraulic cylinder 15 is fixedly installed on the top of the fixed frame 14. A lifting platform 16 is fixedly installed on the output shaft of the second hydraulic cylinder 15. A first guide rod 17 is fixedly installed at both ends of the top of the lifting platform 16. The first guide rod 17 is slidably installed on the fixed frame 14. A drill bit assembly 18 is fixedly installed at the bottom of the lifting platform 16. When drilling, the second hydraulic cylinder 15 drives the lifting platform 16 to move up and down, and the drill bit assembly 18 drills holes in the valve end cap.

[0028] In this embodiment, slide blocks 19 are fixedly installed on the left and right side walls of the moving table 3. A second guide rod 20 is slidably installed on the slide block 19. The second guide rod 20 extends to the front and rear ends of the worktable 1. Support seats 21 are fixedly installed at both ends of the second guide rod 20. The support seats 21 are fixedly installed on the top of the worktable 1. A mounting frame 22 is fixedly installed at the rear end of the mounting groove 2. A third hydraulic cylinder 23 is fixedly installed on the mounting frame 22. The output end of the third hydraulic cylinder 23 is fixedly connected to the moving table 3. A through groove 24 is opened on the bottom wall of the mounting groove 2. The through groove 24 avoids components such as the first hydraulic cylinder 9 and the drive motor 11. When disassembling or assembling the valve end cover, the moving table 3 is driven to move to the front end of the worktable 1 by the third hydraulic cylinder 23, which facilitates the disassembly or assembly of the valve end cover by the operator. During the processing, the offset distance between the center of the clamping seat 4 and the drill bit assembly 18 is controlled by the third hydraulic cylinder 23 to process the drilling of valve end covers of different diameters.

[0029] In this invention, during processing, the operator places the workpiece to be processed onto the clamping seat 4. The operator then activates the first hydraulic cylinder 9 via an external controller. The first hydraulic cylinder 9 drives the drive seat 6 to move downwards. Under the combined action of the T-shaped block 51 and the T-shaped groove 63, the clamping blocks 5 move closer together under the guidance of the guide groove 43, thereby clamping the workpiece. This eliminates the need for manual clamping and fixing of the workpiece, making the workpiece assembly and disassembly process easier and improving the processing efficiency. This is beneficial for drilling large batches of valve end caps. After the workpiece is fixed, the position of the moving table 3 is adjusted by the third hydraulic cylinder 23 so that the position of the workpiece to be drilled is aligned with the drill bit assembly 18. Then, the drill bit assembly 18 moves downwards under the drive of the second hydraulic cylinder 15 to drill the workpiece. After drilling one hole, the second hydraulic cylinder 15 drives the drill bit assembly 18 to rise, and then the drive motor 11 drives the clamping seat 4 to rotate, thereby adjusting the angle of the workpiece to achieve circumferential drilling of the valve end cap.
