Technical Field

[0001] This utility model relates to the field of radial drilling technology for valve body parts, specifically a radial drilling positioning device for valve body parts. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Based on their function, they can be classified as shut-off valves, check valves, regulating valves, etc.

[0003] During valve manufacturing, radial drilling is required for the valve body. Existing radial drilling devices cannot stably clamp the valve body and are very inconvenient for centering, making them difficult for users to operate.

[0004] To address the aforementioned issues, an improved radial drilling positioning device for valve body parts is now designed. Utility Model Content

[0005] The purpose of this utility model is to provide a radial drilling positioning device for valve body parts to solve the problems mentioned in the background art.

[0007] A radial drilling positioning device for valve body parts includes a fixed frame. A first sliding groove is horizontally formed on one side wall of the fixed frame. The side of the fixed frame away from the first sliding groove is vertically mounted on a drilling device. Two clamping positioning plates for clamping and positioning the valve body are provided on the side of the first sliding groove away from the fixed frame. A slider that cooperates with the first sliding groove is installed on the end of the clamping positioning plate near the fixed frame. The slider is slidably connected to the inner wall of the first sliding groove. A driving mechanism for driving the two clamping positioning plates to move relative to each other is provided inside the fixed frame.

The clamping positioning plate and the blocking columns are integrally formed. A positioning cone block is installed at one end of the fixed column, and a fixed plate is installed at the end of the fixed column away from the positioning cone block. A second sliding groove is provided on the side wall of both the fixed column and the positioning cone block to cooperate with the blocking column.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 In this embodiment of the present invention, a radial drilling positioning device for valve body parts includes a fixed frame 1. A first sliding groove 2 is horizontally formed on one side wall of the fixed frame 1. The side of the fixed frame 1 away from the first sliding groove 2 is vertically mounted on a drilling device. Two clamping positioning plates 4 for clamping and positioning the valve body are provided on the side of the first sliding groove 2 away from the fixed frame 1. A slider 3 that cooperates with the first sliding groove 2 is installed on the end of the clamping positioning plate 4 near the fixed frame 1. The slider 3 is slidably connected to the inner wall of the first sliding groove 2. A driving mechanism for driving the two clamping positioning plates 4 to move relative to each other is provided inside the fixed frame 1. A positioning mechanism for center positioning the valve body is provided on the clamping positioning plate 4.

[0024] The driving mechanism includes a rotating rod 13, which is horizontally arranged inside the fixed frame 1. The rotating rod 13 is parallel to the first sliding groove 2. One end of the rotating rod 13 passes through the side wall of the fixed frame 1 and is equipped with a motor 10 for driving the rotating rod 13 to rotate. The motor 10 is mounted on the side wall of the fixed frame 1. The end of the rotating rod 13 away from the motor 10 is rotatably connected to the inner wall of the fixed frame 1. A bidirectional screw 12 is installed on the side wall of the rotating rod 13 inside the fixed frame 1. Moving blocks 11 are rotatably connected to the two opposite threads of the bidirectional screw 12. The moving blocks 11 move along the inner wall of the fixed frame 1. The moving blocks 11 correspond one-to-one with the clamping positioning plates 4. The end of the moving block 11 near the clamping positioning plates 4 is mounted on the end of the slider 3 away from the clamping positioning plates 4.

[0025] When in use, start the motor 10. The output end of the motor 10 drives the rotating rod 13 to rotate. The rotating rod 13 drives the bidirectional screw 12 to rotate. Under the action of the screw, the bidirectional screw 12 drives the two moving blocks 11 to move relative to each other. The moving blocks 11 drive the slider 3 to move. The slider 3 drives the clamping positioning plate 4 to move, thereby causing the two clamping positioning plates 4 to move away from or closer to each other.

[0026] The positioning mechanism includes a fixed post 7. A through hole 14 is provided at the center of the clamping positioning plate 4. Several blocking posts 15 are installed in a circular array on the inner wall of the through hole 14. The clamping positioning plate 4 and the blocking posts 15 are integrally formed. A positioning cone block 9 is installed at one end of the fixed post 7. A fixed plate 5 is installed at the end of the fixed post 7 away from the positioning cone block 9. A second sliding groove 17 is provided on the side wall of both the fixed post 7 and the positioning cone block 9 to cooperate with the blocking post 15. The second sliding groove 17 slides on the side wall of the blocking post 15. The side wall of the fixed post 7 moves along the inner wall of the through hole 14. The tip of the positioning cone block 9 faces the center of the fixed frame 1. The clamping positioning plate 4 is disposed between the positioning cone block 9 and the fixed plate 5. A tension spring 8 is installed between the fixed plate 5 and the clamping positioning plate 4 to pull the fixed plate 5 closer to the clamping positioning plate 4. The two ends of the tension spring 8 are respectively installed on the clamping positioning plate 4 and the fixed plate 5.

[0027] The fixing plate 5 has a plurality of limiting holes 16 arranged in a circular array. A limiting rod 6 is slidably connected to the inner wall of the limiting hole 16. One end of the limiting rod 6 near the center of the fixing frame 1 is installed on the clamping positioning plate 4.

[0028] When in use, the two ends of the valve body are fitted onto the positioning cone blocks 9. The two positioning cone blocks 9 will align the central axis of the valve body. When the two clamping positioning plates 4 approach each other, the positioning cone blocks 9 will move towards the fixed plate 5. The positioning cone blocks 9 push the fixed column 7 to move, the fixed column 7 pushes the fixed plate 5 to move, and the fixed plate 5 stretches the tension spring 8 until the two clamping positioning plates 4 clamp and fix the valve body.

[0029] Working principle of a radial drilling positioning device for valve body parts:

[0030] In use, the two ends of the valve body are fitted onto the positioning cone blocks 9. The two positioning cone blocks 9 will align the central axis of the valve body. Then, the motor 10 is started. The output end of the motor 10 drives the rotating rod 13 to rotate. The rotating rod 13 drives the bidirectional screw 12 to rotate. Under the action of the thread, the bidirectional screw 12 drives the two moving blocks 11 to move relative to each other. The moving blocks 11 drive the slider 3 to move. The slider 3 drives the clamping positioning plate 4 to move, so that the two clamping positioning plates 4 move closer to each other.

[0031] When the two clamping positioning plates 4 approach each other, the positioning cone block 9 will move to one side of the fixed plate 5. The positioning cone block 9 pushes the fixed column 7 to move, the fixed column 7 pushes the fixed plate 5 to move, and the fixed plate 5 stretches the tension spring 8 until the two clamping positioning plates 4 clamp and fix the valve body.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
