DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See attached Figure 1-7 A valve body drilling device comprises a support seat 1 for carrying a valve body, a cylinder 2 is arranged on the support seat 1, a rotatable output rod 3 is arranged at the output end of the cylinder 2, and a support plate 4 is connected through the output rod 3, a plurality of support rods 5 are arranged in the support plate 4, and clamp units are arranged at both ends of the support rod 5 for clamping the valve body, and the two clamp units form a mirror image relative to the circumference of the output rod 3, so that the distances between the two clamp units and the axis of the support rod 5 are the same;

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

[0030] When in use, the valve body is clamped by two clamp units, and the bottom of the valve body is located on the support seat 1, providing necessary support and stability for the opening of the valve body. When the opening of the valve body is completed, the cylinder 2 is started. At this time, the output rod 3 drives the support plate 4 and the support rod 5 to move, and further drives the valve body to move through the two clamp units. In this process, the fixed column 22 moves relatively along the slide groove 31. When the valve body is removed from the top of the support seat 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, the output rod 3 rotates under the action of the fixed column 22, and further the two clamp units drive the valve body to rotate 180°, so that the valve body A 180° flip is formed, and the fixed column 22 moves from the arc groove 32 to the other slide groove 31. The control cylinder 2 drives the output rod 3 to retract. The fixed column 22 will move along the slide groove 31. The rotation of the first blocking mechanism will not hinder the relative movement of the fixed column 22 in the slide groove 31. The two clamp units further drive the flipped valve body back to the support seat 1. At this time, the other side of the flipped valve body can be drilled, avoiding the tedious steps of manually loosening the clamp, flipping and fixing the valve body in traditional operations, which not only significantly improves the continuity and automation of the drilling operation, but also greatly improves the overall drilling efficiency, and realizes an efficient and precise valve body processing process.

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

[0032] A second blocking mechanism is provided at the tail of the arc groove 32, and the second blocking mechanism includes a limit block 342. A receiving groove 341 for receiving the limit block 342 is provided in the arc groove 32. The bottom of the limit block 342 slides in the receiving groove 341, and a spring 343 is provided at the bottom thereof to abut against the bottom wall of the receiving groove 341. The side of the limit block 342 facing the arc groove 32 is an inclined surface to ensure the passage of the fixed column 22, and the side of the limit block 342 facing the slide groove 31 is a horizontal surface to limit the passage of the fixed column 22. The fixed column 22 enters through the arc groove 32 When it reaches the inside of the slide groove 31, the limit block 342 is squeezed and enters the accommodating groove 341. At this time, the limit block 342 does 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 limit block 342, the limit block 342 cannot be pushed. At this time, the limit 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 it moves horizontally relative to 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 clamp unit includes a clamp ring 61, in which a plurality of clamping plates 62 are rotatably connected. An arc-shaped push groove 63 is provided in the clamping plate 62. A push rod 64 is slidably connected in the push groove 63 to push the clamping plate 62 to the center of the clamp ring 61. A connecting arm 65 is connected to the end of the push rod 64. 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 sleeved on the clamp ring 61 and forms a rotational connection therewith to prevent the valve body from reaching the center position of the clamp ring 61 and control the rotation of the rotating ring 66. At this time, the connecting arm 65 rotates with the rotating ring 66, further causing the push rod 64 to move in the push groove 63. At this time, a plurality of clamping plates 62 are deflected at the same time, further causing the plurality of clamping plates 62 to clamp the valve body at the same time, thereby greatly improving the clamping efficiency.

[0034] A first motor 7 is provided on the top of the support seat 1, and a gear 8 is provided at the output end of the first motor 7. A plurality of teeth 68 matching the gear 8 are provided on the outer wall of the rotating ring 66. The two rotating rings 66 are connected by a plurality of 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 the plurality of vertical rods 67, the rotating rings 66 on the upper and lower sides rotate synchronously. At this time, the two clamping units can clamp the upper and lower sides of the valve body synchronously, thereby further improving the clamping efficiency.

[0035] A support column 9 is provided inside the support seat 1, and the support seat 1 can be displaced up and down along the direction of the support column 9. The specific structure belongs to the prior art and will not be described in detail in the application. A drilling box 10 is provided on the top of the support column 9, and a second motor 11 is provided on the bottom wall of the drilling box 10. A drilling arm 12 is provided at the output end of the second motor 11, and a third motor 13 is provided on the drilling arm 12. A drill bit 14 is provided at the bottom of the third motor 13. The second motor 11 and the third motor 13 are started. At this time, 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] A vertical track groove 15 is provided in the support seat 1, and 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 internal thread of the slider 16 is connected to a screw 17, and a knob 18 is provided on the top of the screw 17. When the knob 18 is turned, the screw 17 rotates, further causing the slider 16 to slide in the track groove 15. At this time, the cylinder 2 will drive the two clamp units to move up and down, making it convenient for the two clamp units to clamp valve bodies of different sizes.
