Abstract
Description
Technical Field
[0001] This application relates to the field of valve body processing, and more specifically, to a processing apparatus for a control valve. Background Technology
[0002] Control valves are valve body structures with flange interfaces. When processing control valves, it is often necessary to drill holes in the flange interface so that other pipelines can be connected to the control valve. However, in the existing technology, the control valve is often positioned by pressing the control valve together with two clamping surfaces and then limiting the control valve with a shaft, thereby achieving complete positioning of the control valve.
[0003] However, during the positioning process of the control valve, the control valve itself has a complex structure. Forcibly pressing the control valve with a pressure surface makes it difficult to quickly position the control valve. At the same time, it may also cause the part of the control valve that is pressed to have too small a contact area with the pressure surface, resulting in excessive pressure on the control valve. This may lead to damage to the control valve during positioning. Summary of the Invention
[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.
[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a processing apparatus for a control valve. The control valve is configured as a flange interface with two circular surfaces and a valve body for connecting the flange interfaces with the two circular surfaces. A curved surface is formed on the valve body. The processing apparatus includes: a first positioning member for forming a first positioning surface with a variable size; and a second positioning member for forming a second positioning surface with a variable shape. Two of both the first and second positioning members are provided. The first positioning surface is used to abut against the flange interface with the circular surface; and the second positioning surface is used to abut against the curved surface formed on the valve body.
[0006] Furthermore, the processing device further includes: a first driving member and a second driving member; the first driving member is used to make the first positioning surface formed by the first positioning member abut against the circular flange interface; and also to make the first positioning surface away from the circular flange interface; the second driving member is used to make the second positioning surface formed by the second positioning member abut against the curved surface on the valve body; and also to make the second positioning surface away from the valve body; when both the first positioning surface and the second positioning surface are in contact with the regulating valve, the regulating valve is in a positioning state; when both the first positioning surface and the second positioning surface are away from the regulating valve, the regulating valve is in a replaceable state.
[0007] Furthermore, the processing device also includes a third positioning element; the third positioning element is used to form the third positioning surface; the third positioning surface is used to abut against the end face of the flange interface having a circular surface.
[0008] Furthermore, the first driving member can also be used to move the third positioning surface formed by the third positioning member closer to and further away from the end face of the flange interface with a circular surface.
[0009] Furthermore, the first positioning element includes: four first power structures and two flexible limiting structures; wherein the two first power structures are respectively used to connect to the two ends of the flexible limiting structure; the first power structures are used to increase and decrease the length of the flexible limiting structure between the two first power structures.
[0010] Furthermore, the first power structure includes a first mounting frame, a first drive motor, and a winding roller; the flexible limiting structure is one of rope and cloth; the flexible limiting structure is wound around the first winding roller; the first drive motor is used to drive the first winding roller to rotate; the first winding roller directly or indirectly abuts against a flange interface with a circular surface.
[0011] Furthermore, the first power structure also includes a guide roller, which is rotatably connected to the first mounting frame; the flexible limiting structure bypasses the guide roller so that the guide roller guides the flexible limiting structure; when the regulating valve is in the positioning state, the guide roller abuts against the circular surface.
[0012] Furthermore, the second positioning element includes: a second mounting bracket, a second winding roller, a flexible cloth, and a second drive motor; The second winding roller is used to abut against the curved surface on the valve body; the flexible part is wound around the second winding roller, and the second drive motor is used to drive the second winding roller to rotate.
[0013] The beneficial effects of this application are as follows: it provides a processing device for a control valve that achieves complete positioning by abutting the outer wall surface of the control valve with a positioning surface that matches the shape of the control valve, and greatly reduces the phenomenon of excessive local pressure between the control valve and the control valve during positioning, thereby greatly improving the stability of positioning and greatly reducing damage to the control valve during positioning.

[0023] Reference Figure 1-10 , A processing apparatus for a control valve, the control valve being configured as a flange interface 1 having two circular surfaces 11 and a valve body 2 for connecting the flange interface 1 to the two circular surfaces 11.

The second positioning surface is used to abut against the curved surface 21 formed on the valve body 2.
[0026] Specifically, the processing device further includes a first driving member 5 and a second driving member 7. The first driving member 5 is used to make the first positioning surface formed by the first positioning member 3 abut against the circular flange interface 1; and also to make the first positioning surface away from the circular flange interface 1; the second driving member 7 is used to make the second positioning surface formed by the second positioning member 4 abut against the curved surface 21 on the valve body 2; and also to make the second positioning surface away from the valve body 2; when both the first positioning surface and the second positioning surface are in contact with the regulating valve, the regulating valve is in a positioning state; when both the first positioning surface and the second positioning surface are away from the regulating valve, the regulating valve is in a replaceable state.
[0027] The first driving component 5 includes: a fixed frame 51, a first power motor 52, a first drive screw 53, a first drive nut 54, a first moving frame 55, a guide block 56, a guide rod 57, a second power motor 58, a second drive screw 59, a second drive nut 60, a third power motor 61, a third drive screw 62, and a third drive nut 63. The number of parts in the first driving component 5 is shown in the attached drawings of the instruction manual.
[0028] The processing device also includes a support platform 9. A fixed frame 51 is mounted on and fixed to the support platform 9. A first drive screw 53 is rotatably connected to the fixed frame 51. A first power motor 52 is mounted on the fixed frame 51 and drives the first drive screw 53 to rotate. A first drive nut 54 is threadedly connected to the first drive screw 53. A movable frame is fixed to the first drive nut 54. The first power motor 52 drives the movable frame to move through the first drive screw 53 and the first drive nut 54. A second power motor 58 is mounted on the movable frame. A second drive screw 59 is rotatably connected to the movable frame. A second drive nut 60 is threadedly connected to the second drive screw 59.

[0029] The second driving component 7 includes: a first fixed plate 71, a second fixed plate 72, and a driving cylinder 73. The first fixed plate 71 is fixed to the movable frame, the second fixed plate 72 is fixed to the first fixed plate, and the driving cylinder 73 is mounted on the second fixed plate 72.
[0030] Specifically, the processing device further includes a third positioning element 8; the third positioning element 8 is used to form the third positioning surface; the third positioning surface is used to abut against the end face of the flange interface 1 having a circular surface 11. The third positioning element 8 is constructed as a plate structure and is fixedly connected to the first fixing plate 71. A plurality of slots 81 are formed on the third positioning element 8, and the slots 81 allow a drill bit for drilling to pass through the third positioning element 8 to drill holes in the flange interface 1.
[0031] Specifically, the first driving member 5 can also be used to move the third positioning surface formed by the third positioning member 8 closer to and further away from the end face of the flange interface 1 with the circular surface 11. The third positioning member 8 is mounted on the first fixed plate 71, so that the third positioning member 8 moves with the movement of the moving frame. Thus, the third positioning member 8 will also move closer to and further away from the end face of the flange interface 1 with the circular surface 11.
[0032] Specifically, the first positioning element 3 includes: four first power structures 31 and two flexible limiting structures 32; wherein the two first power structures 31 are respectively used to connect to the two ends of the flexible limiting structure 32; the first power structures 31 are used to increase and decrease the length of the flexible limiting structure 32 between the two first power structures 31.
[0033] Specifically, the first power structure 31 includes a first mounting frame 311, a first drive motor 312, and a winding roller 313; the flexible limiting structure 32 is either a rope or a cloth; the flexible limiting structure 32 is wound around the first winding roller; the first drive motor 312 is used to drive the first winding roller to rotate; the first winding roller directly or indirectly abuts against the flange interface 1 with a circular surface 11.
[0034] Specifically, the first power structure 31 further includes a guide roller 314, which is rotatably connected to the first mounting frame 311; the flexible limiting structure 32 bypasses the guide roller 314 so that the guide roller 314 guides the flexible limiting structure 32; when the regulating valve is in the positioning state, the guide roller 314 abuts against the circular surface 11.
[0035] The first mounting bracket 311 is fixed to the third drive nut 63.
[0036] Specifically, the second positioning component 4 includes: a second mounting bracket 41, a second winding roller 42, a flexible cloth 43, and a second drive motor 44; the second winding roller 42 is used to abut against the curved surface 21 on the valve body 2; the flexible part is wound around the second winding roller 42, and the second drive motor 44 is used to drive the second winding roller 42 to rotate. The second drive bracket is connected to the output end of the drive cylinder 73.
[0037] Workflow: The regulating valve is moved to the upper part of the worktable by the robotic arm. Then, the first power motor 52 drives the first drive screw 53 to rotate, which drives the moving frame to move through the first drive nut 54. This causes the two moving frames to move closer to each other, that is, the two moving frames to move closer to the position of flange interface 1. Then, the second power motor 58 drives the second drive screw 59 to rotate, which drives the third drive screw 62 to move through the second drive nut 60. This causes the third drive screw 62 to move to the position of flange interface 1. Then, the third power motor 61 drives the third drive screw 62 to rotate. The third drive screw 62 drives the first mounting frame 311 to move through the third drive nut 63. This allows the first mounting frame 311 to move vertically and laterally, which causes multiple first mounting frames 311 to move closer to the edge of flange interface 1.
[0038] The first drive motor 312 drives the winding roller to rotate, and the winding roller winds the flexible limiting structure 32, making the length of the flexible limiting structure 32 between the two winding rollers shorter. This makes the shape enclosed by the flexible limiting structure 32 smaller, so that the flexible limiting structure 32 is tightly wound on the circular surface 11 of the flange interface 1. This achieves a first positioning surface that matches the circular surface 11 and abuts against the circular surface 11, positioning the circular surface 11. In this way, the regulating valve to be processed cannot move in the direction of abutting against the circular surface 11. To further limit the movement, when the moving frame moves, it drives the third positioning member 8 to approach the regulating valve, making the regulating valve unable to move along the axial direction of the first positioning surface.
[0039] Then, the drive cylinder 73 causes the second winding roller 42 on the second drive motor 44 to abut against the side of the regulating valve. The second winding roller 42 causes the flexible cloth 43 between the two second winding rollers 42 to fit against the side of the regulating valve, so that the flexible cloth 43 can better abut against the irregular curved surface 21 on the regulating valve, thereby limiting the regulating valve.
