[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] See attached document Figure 1-7 A valve body drilling device includes a support base 1 for supporting the valve body, a cylinder 2 on the support base 1, a rotatable output rod 3 at the output end of the cylinder 2, and a support plate 4 connected to the output rod 3. The support plate 4 contains multiple support rods 5, and each end of the support rod 5 is provided with a clamping unit for clamping the valve body. The two clamping units are mirror images of each other in the circumference of the output rod 3, so that the distances from the two clamping units to the axis of the support rod 5 are the same.

[0029] The outer wall of the output rod 3 is provided with two horizontal sliding grooves 31 and two arc-shaped grooves 32 along its outer wall. The two horizontal sliding grooves 31 are symmetrically arranged. The two ends of the arc-shaped grooves 32 are respectively connected to the two sliding grooves 31, so that the two horizontal sliding grooves 31 are connected to each other through the arc-shaped grooves 32. The cylinder 2 is provided with fixed rods 21 symmetrically arranged on both sides. One side of the fixed rod 21 is provided with a fixed post 22 inserted into the sliding groove 31. The fixed post 22 can move along the sliding groove 31 and the arc-shaped groove 32. The end of the arc-shaped groove 32 and located in the sliding groove 31 is provided with a rotatable first blocking mechanism to control the fixed post 22 to enter the arc-shaped groove 32 through the sliding groove 31.

[0030] In use, the valve body is clamped by two clamping units, with its bottom resting on the support base 1, providing necessary support and stability for the valve body's opening. After the valve body is opened, the cylinder 2 is activated. At this time, the output rod 3 drives the support plate 4 and support rod 5 to move, and further drives the valve body to move through the two clamping units. During this process, the fixed column 22 moves relative to the slide groove 31. When the valve body moves away from the top of the support base 1, the fixed column 22 is blocked by the first blocking mechanism and moves from the slide groove 31 to the arc groove 32. At this time, under the action of the fixed column 22, the output rod 3 rotates, further causing the two clamping units to drive the valve body to rotate 180°, and thus the valve body... A 180° rotation is achieved, at which point the fixed column 22 moves from the arc groove 32 into another slide groove 31. At this time, the control cylinder 2 drives the output rod 3 to retract, and the fixed column 22 will move along the slide groove 31. The rotation of the first blocking mechanism will not hinder the movement of the fixed column 22 relative to the slide groove 31. Furthermore, the two clamping units drive the rotated valve body back onto the support seat 1. At this time, the other side of the rotated valve body can be drilled, avoiding the tedious steps of manually loosening the clamps, rotating and fixing the valve body again in the traditional operation. This not only significantly improves the continuity and automation of the drilling operation, but also greatly improves the overall drilling efficiency, realizing an efficient and precise valve body processing flow.

[0031] The first blocking mechanism includes a fixed shaft 331 fixed in the arc-shaped groove 32. A limiting plate 332 and a torsion spring 333 are sleeved on the outer wall of the fixed shaft 331. The two ends of the torsion spring 333 are respectively connected to the limiting plate 332 and the inner wall of the arc-shaped groove 32. A limiting groove 334 is opened in the slide 31 to support the end of the limiting plate 332 away from the fixed shaft 331. When the fixed column 22 moves relative to the cylinder 2 along the slide 31, the fixed column 22 will enter the arc-shaped groove 32 under the action of the limiting plate 332, so that the output rod 3 rotates 180° and the valve body flips. When the fixed column 22 moves relative to the cylinder 2 in the opposite direction along the slide 31, the fixed column 22 pushes the limiting plate 332. At this time, the limiting plate 332 will deflect. The fixed column 22 can continue to move relative to the slide 31 without affecting the direction of the valve body.

[0032] The tail end of the arc-shaped groove 32 is provided with a second blocking mechanism, which includes a limiting block 342. A receiving groove 341 is formed within the arc-shaped groove 32 to accommodate the limiting block 342. The bottom of the limiting block 342 slides within the receiving groove 341, and a spring 343 abuts against the bottom wall of the receiving groove 341 at its bottom. The side of the limiting block 342 facing the arc-shaped groove 32 is inclined to ensure the passage of the fixed post 22, while the side of the limiting block 342 facing the slide 31 is horizontal to restrict the passage of the fixed post 22. The fixed post 22 enters through the arc-shaped groove 32. When the fixed column 22 reaches the inside of the slide groove 31, the limiting block 342 will be squeezed and enter the receiving groove 341. At this time, the limiting block 342 will not affect the movement of the fixed column 22. When the fixed column 22 moves in the slide groove 31 and passes the position of the limiting block 342, it cannot push the limiting block 342. At this time, the limiting block 342 will relatively hinder the fixed column 22 from entering the arc groove 32, so that the fixed column 22 is more stable when moving horizontally in the slide groove 31, avoiding the fixed column 22 from entering the arc groove 32, and ensuring the precise control of the rotation angle of the output rod 3.

[0033] The clamping unit includes a clamping ring 61, with several clamping plates 62 rotatably connected to the inner circumference of the clamping ring 61. Each clamping plate 62 has an arc-shaped push groove 63, and a push rod 64 is slidably connected within the push groove 63 to push the clamping plate 62 towards the center of the clamping ring 61. A connecting arm 65 is connected to the end of the push rod 64, and a rotating ring 66 is connected to the side of the connecting arm 65 away from the push rod 64. The rotating ring 66 is fitted onto the clamping ring 61 and rotatably connected to it, securing the valve body to the center position of the clamping ring 61. Controlling the rotation of the rotating ring 66 causes the connecting arm 65 to rotate along with the rotating ring 66, further causing the push rod 64 to move within the push groove 63. Simultaneously, the clamping plates 62 deflect, further clamping the valve body simultaneously, greatly improving clamping efficiency.

[0034] The top of the support base 1 is equipped with a first motor 7, and the output end of the first motor 7 is equipped with a gear 8. The outer wall of the rotating ring 66 is equipped with several teeth 68 that cooperate with the gear 8. The two rotating rings 66 are connected by multiple vertical rods 67 so that the two clamping units can move synchronously. When the first motor 7 is started, the gear 8 drives the rotating ring 66 to rotate through the teeth 68. At this time, under the action of several vertical rods 67, the upper and lower rotating rings 66 rotate synchronously. At this time, the two clamping units can clamp the upper and lower sides of the valve body synchronously, which further improves the clamping efficiency.

[0035] The support base 1 has a support column 9 inside. The support base 1 can move up and down along the direction of the support column 9. The specific structure belongs to the prior art and is under application, so it will not be described in detail. The top of the support column 9 is equipped with a drilling box 10. The bottom wall of the drilling box 10 is equipped with a second motor 11. The output end of the second motor 11 is equipped with a drilling arm 12. The drilling arm 12 is equipped with a third motor 13. The bottom of the third motor 13 is equipped with a drill bit 14. When the second motor 11 and the third motor 13 are started, the second motor 11 drives the drilling arm 12 to rotate, and the third motor 13 drives the drill bit 14 to rotate. The valve body can be circumferentially opened without rotating the valve body, which greatly improves the opening efficiency of the valve body.

[0036] The support base 1 has a vertical track groove 15. A slider 16 connected to the cylinder 2 is slidably connected in the track groove 15 to drive the cylinder 2 to move up and down. The slider 16 is internally threaded with a screw 17. The top of the screw 17 is provided with a knob 18. When the knob 18 is turned, the screw 17 rotates, which further causes the slider 16 to slide in the track groove 15. At this time, the cylinder 2 will drive the two clamping units to move up and down, so that the two clamping units can clamp valve bodies of different sizes.
