Description

Technical Field

[0001] This invention belongs to the field of water pump control valve technology, and particularly relates to a multi-functional water pump control valve flange face positioning and processing device, as well as a multi-functional water pump control valve flange face positioning working method. Background Technology

[0002] Pump control valves are multi-functional valves that use a pilot-operated method to control flow. These valves should generally be installed horizontally in pipelines. They are suitable for water distribution lines where flow and pressure need to be controlled, maintaining a predetermined flow rate, limiting excessive flow to a predetermined value, and appropriately reducing upstream high pressure. Even if the pressure upstream of the main valve changes, it will not affect the flow rate downstream of the main valve.

[0003] When machining the water pump control valve, it is necessary to position the flange face on top of the control valve. Since the center of gravity is not in the middle of the water pump control valve, the user needs to adjust the position of the water pump control valve multiple times to make the flange face of the control valve perpendicular to the vertical plane, which facilitates subsequent machining work. Summary of the Invention

[0004] This invention addresses the problem in existing technologies where the position of the control valve needs to be adjusted to ensure that the flange face of the control valve is perpendicular to the vertical plane, and proposes the following technical solution:

[0005] A multi-functional water pump control valve flange face positioning and machining device, including:

[0006] A support assembly for placing a control valve and positioning its top flange face, the support assembly including a placement frame, the bottom of which is provided with a positioning frame, the flange face of the inverted control valve being in contact with the surface of the positioning frame;

[0007] A rotating assembly is used to flip a carrying assembly. The rotating assembly includes a driving component and a rotating shaft. The output end of the driving component is provided with a driving bevel gear. A driven bevel gear is meshed with one side of the driving bevel gear. The driven bevel gear is fixedly connected to the rotating shaft and is coaxial with it.

[0008] The positioning frame can be used to restrict the inverted control valve, making the control valve flange face perpendicular to the vertical plane. The rotating component can be used to flip the placement rack and positioning frame, and after flipping, the control valve flange face is perpendicular to the vertical plane again, thus completing the positioning of the control valve flange face. There is no need to adjust the control valve, making the positioning of the control valve flange face much simpler.

[0009] As a preferred embodiment of the above technical solution, an adjustment part is provided between the positioning frame and the placement frame, and the adjustment part adjusts the positioning frame from a horizontal state to a deflected state.

[0010] The adjustable part can adjust the state of the positioning frame, so that the positioning frame can have two states: horizontal and tilted.

[0011] As a preferred embodiment of the above technical solution, the adjustment part includes a rotating part and a moving part, which are fixedly connected to both ends of the positioning frame. The rotating part is rotatably inserted into the bottom of the placement frame, and both ends of the moving part are fixedly connected to the placement frame by bolts. An extension rod is sleeved on the surface of the moving part, and a limit rod is provided at the end of the extension rod. A corresponding insertion groove is opened on the surface of the placement frame.

[0012] When the positioning frame is in a horizontal position, it can position the horizontal flange face of the control valve. When the positioning frame is in an inclined position, it can position the inclined flange face of the control valve, so that the device can be used for positioning two different control valve flange faces.

[0013] As a preferred embodiment of the above technical solution, it further includes a clamping assembly, which includes a lead screw and a second driving component. Both ends of the lead screw are fitted with movable sliders, and one end of the movable slider is fixedly connected to a clamping block.

[0014] The clamping components can center and push the control valve, and with the cooperation of the positioning frame, fix the control valve in place, preventing the control valve from moving during the processing and affecting the processing work.

[0015] As a preferred embodiment of the above technical solution, the lead screw has reverse threads at both ends, and the threaded surfaces at both ends of the lead screw are threadedly engaged with the corresponding movable slider.

[0016] Because the screw has reverse threads at both ends, the two moving sliders can move in opposite directions or in opposite directions at the same time, thereby pushing the gripping block synchronously.

[0017] As a preferred embodiment of the above technical solution, the surface of the gripping block is provided with a protrusion, and the protrusion is made of rubber.

[0018] Because the protrusion is made of rubber, it is squeezed and deformed after contacting both ends of the control valve, increasing the friction at both ends of the control valve and making the gripping block grip the control valve more stably.

[0019] As a preferred embodiment of the above technical solution, the rotating shaft is rotatably inserted into the bracket, and the driving component is mounted on the bracket.

[0020] The bracket provides support for the rotation axis, enabling the placement rack and positioning frame to complete the flipping operation normally.

[0021] The working method of the multi-functional water pump control valve flange face positioning and machining device includes the following steps.

[0022] S1. Place the control valve;

[0023] Invert the control valve and place it on the mounting rack, ensuring the valve flange face is flush with the positioning frame surface so that the flange face to be positioned is perpendicular to the vertical plane.

[0024] S2, Tilting load-bearing component;

[0025] When the drive unit is started, it drives the active bevel gear to rotate, causing the driven bevel gear and the rotating shaft to rotate. The placement rack and positioning frame drive the control valve to rotate 180 degrees.

[0026] S3, machining control valve;

[0027] After the control valve flange face is flipped over and becomes perpendicular to the vertical plane again, the positioned control valve can then be machined.

[0028] The beneficial effects of this invention are as follows:

[0029] 1. The positioning frame can be used to restrict the inverted control valve, so that the flange face of the control valve is perpendicular to the vertical plane. The rotating component can be used to flip the placement rack and positioning frame. After flipping, the flange face of the control valve is perpendicular to the vertical plane again, thus completing the positioning of the flange face of the control valve. There is no need to adjust the control valve, and the positioning of the flange face of the control valve is simpler.

[0030] 2. The adjustable part can adjust the position of the positioning frame. When the positioning frame is in a horizontal position, it can position the horizontal flange face of the control valve. When the positioning frame is in an inclined position, it can position the inclined flange face of the control valve, so that the device can be used for positioning two different control valve flange faces.

[0031] 3. The clamping components can center and push the control valve, and fix the control valve in place with the help of the positioning frame, so as to prevent the control valve from moving during the processing and affecting the processing work. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0037] Example

[0038] Figures 1-3 The multi-functional water pump control valve flange face positioning and machining device includes:

[0039] A support assembly is used to place a control valve and position the top flange face of the control valve. The support assembly includes a placement frame 11, and a positioning frame 12 is provided at the bottom of the placement frame 11. The flange face of the inverted control valve is in contact with the surface of the positioning frame 12.

[0040] A rotating assembly is used to flip the carrying assembly. The rotating assembly includes a drive component 21 and a rotating shaft 22. The drive component 21 is a motor with a worm gear reducer. The output end of the drive component 21 is provided with a driving bevel gear 23. A driven bevel gear 24 is meshed with one side of the driving bevel gear 23. The driven bevel gear 24 is fixedly connected to the rotating shaft 22 and is coaxial with it.

[0041] Before machining the water pump control valve, the top flange face of the control valve must be positioned. The user inverts the control valve and places it on the placement rack 11. After the control valve flange face is in contact with the surface of the positioning frame 12, the positioning flange face must be perpendicular to the vertical plane. Then, the drive component 21 is started to drive the active bevel gear 23 to rotate, and the driven bevel gear 24 rotates accordingly, driving the rotating shaft 22 to rotate until the placement rack 11 and the positioning frame 12 drive the control valve to rotate 180 degrees. After the control valve flange face is rotated, it is perpendicular to the vertical plane again. Then the positioned control valve can be machined.

[0042] The positioning frame 12 can be used to restrict the inverted control valve, so that the flange face of the control valve is perpendicular to the vertical plane. The rotating component can be used to flip the placement frame 11 and the positioning frame 12. After flipping, the flange face of the control valve is perpendicular to the vertical plane again, thus completing the positioning of the flange face of the control valve. There is no need to adjust the control valve, and the positioning of the flange face of the control valve is simpler.

[0043] The working method of the multi-functional water pump control valve flange face positioning and machining device includes the following steps.

[0044] S1. Place the control valve;

[0045] Invert the control valve and place it on the mounting rack 11, with the flange face of the control valve fitting against the surface of the positioning frame 12 so that the flange face to be positioned is perpendicular to the vertical plane:

[0046] S2, Tilting load-bearing component;

[0047] When the drive unit 21 is started, it drives the active bevel gear 23 to rotate, which causes the driven bevel gear 24 and the rotating shaft 22 to rotate. The placement frame 11 and the positioning frame 12 drive the control valve to rotate 180 degrees.

[0048] S3, machining control valve;

[0049] After the control valve flange face is flipped over and becomes perpendicular to the vertical plane again, the positioned control valve can then be machined.

[0050] In the working method of this multi-functional water pump control valve flange face positioning and processing device, the control valve is placed upside down, and the control valve flange face is attached to the surface of the positioning frame 12 so that it is perpendicular to the vertical plane. Then, the rotating component flips the placement frame 11 and the positioning frame 12. After the control valve flange face is flipped, it is perpendicular to the vertical plane again, thus completing the positioning of the control valve flange face. There is no need to adjust the control valve, and the positioning of the control valve flange face is simpler.

[0051] Figure 1 and Figure 3 In the process, an adjustment part is provided between the positioning frame 12 and the placement frame 11, and the adjustment part adjusts the positioning frame 12 from a horizontal state to a deflected state.

[0052] The adjustment part includes a rotating part 31 and a moving part 32. The rotating part 31 and the moving part 32 are fixedly connected to both ends of the positioning frame 12. The rotating part 31 is rotatably inserted into the bottom of the placement frame 11. The two ends of the moving part 32 are fixedly connected to the placement frame 11 by bolts 33. An extension rod 34 is sleeved on the surface of the moving part 32. A limit rod 35 is provided at the end of the extension rod 34. A corresponding insertion groove 36 is opened on the surface of the placement frame 11.

[0053] When positioning different water pump control valves, the two bolts 33 are removed to allow the moving part 32 to be in a free state. Under the action of gravity, the moving part 32 drives the extension rod 34 to deflect downward at a certain angle. The limiting rod 35 moves along the insertion groove 36 to the bottom of the insertion groove 36. The limiting rod 35 and the insertion groove 36 support the extension rod 34 to prevent it from moving again. At this time, the positioning frame 12 is in an inclined state, which facilitates the positioning of the inclined flange surface of the control valve.

[0054] The adjustable part can adjust the state of the positioning frame 12. When the positioning frame 12 is in a horizontal state, it can position the horizontal flange face of the control valve. When the positioning frame 12 is in an inclined state, it can position the inclined flange face of the control valve, so that the device can be used for positioning two different control valve flange faces.

[0055] Figure 2 The device also includes a clamping assembly, which includes a lead screw 41 and a second driving component 42. The second driving component 42 is a motor with a worm gear reducer. Both ends of the lead screw 41 are fitted with movable sliders 43, and one end of the movable slider 43 is fixedly connected to a clamping block 44.

[0056] The lead screw 41 has reverse threads at both ends, and the threaded surfaces at both ends of the lead screw 41 are threadedly engaged with the corresponding movable slider 43.

[0057] The surface of the gripping block 44 is provided with a protrusion 45, which is made of rubber.

[0058] After the control valve is placed, the second drive unit 42 starts and drives the lead screw 41 to rotate. Since the two ends of the lead screw 41 have reverse threads, and the threaded surfaces of the two ends of the lead screw 41 are threadedly engaged with the corresponding moving sliders 43, the two moving sliders 43 move towards each other and drive the clamping block 44 to move. Since the protrusion 45 is made of rubber, the protrusion 45 deforms after contacting the two ends of the control valve and pushes the control valve. The control valve is automatically centered and restricted, which facilitates the clamping and fixing of the control valve.

[0059] The clamping assembly can center and push the control valve, and with the cooperation of the positioning frame 12, fix the control valve to prevent it from moving during the processing and affecting the processing work.

[0060] Figure 1 In this configuration, the rotating shaft 22 is rotatably inserted into the bracket 50, and the driving component 21 is mounted on the bracket 50.

[0061] The bracket 50 is mounted on the external workbench and provides support for the rotating shaft 22, so that the placement rack 11 and the positioning frame 12 can complete the flipping operation normally.

[0062] Working principle:

[0063] Before processing the water pump control valve, the top flange face of the control valve needs to be positioned. After the user inverts the control valve and places it on the placement rack 11, the flange face of the control valve needs to be in a position perpendicular to the vertical plane after it is in contact with the surface of the positioning frame 12. Then the drive component 42 starts and drives the lead screw 41 to rotate. The two moving sliders 43 move towards each other and drive the clamping block 44 to move. After the protrusion 45 contacts the two ends of the control valve, it deforms and pushes the control valve. The control valve is automatically centered and restricted, which makes it convenient to clamp and fix the control valve.

[0064] Subsequently, the drive unit 21 starts and drives the active bevel gear 23 to rotate. The driven bevel gear 24 rotates accordingly and drives the rotating shaft 22 to rotate until the placement frame 11 and the positioning frame 12 drive the control valve to rotate 180 degrees. After the control valve flange face is rotated, it is perpendicular to the vertical plane again. Then the positioned control valve can be processed.

[0065] When positioning different water pump control valves, the two bolts 33 are removed to allow the moving part 32 to be in a free state. Under the action of gravity, the moving part 32 drives the extension rod 34 to deflect downward at a certain angle. The limiting rod 35 moves along the insertion groove 36 to the bottom of the insertion groove 36. The limiting rod 35 and the insertion groove 36 support the extension rod 34 to prevent it from moving again. At this time, the positioning frame 12 is in an inclined state, which facilitates the positioning of the inclined flange surface of the control valve.

[0066] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
