Description

Technical Field

[0001] This utility model belongs to the field of butterfly valve plate processing technology, specifically relating to a rapid processing and positioning device for the guide hole of the valve shaft of a butterfly valve plate. Background Technology

[0002] A pinless butterfly valve is a type of valve that uses a disc-shaped opening and closing element to reciprocate approximately 90 degrees to open, close, and regulate the fluid passage. Pinless butterfly valves are not only simple in structure, small in size, lightweight, and material-efficient, with small installation dimensions, but also have low driving torque and are easy and quick to operate. A search revealed that application number "CN202222863615.X" discloses "a novel pinless valve plate processing and positioning device," which describes a method where "rotating the handle drives the cam to rotate and compress the bent plate, which moves outward and simultaneously compresses the spring. The bent plate then moves the clamping plate outward, placing the pinless valve plate inside the clamping plate. Releasing the handle allows the compressed spring to return the bent plate to its original position, which in turn moves the clamping plate back to its original position, thus positioning the pinless valve plate. This fixing method replaces threaded connections." The method of fixing the pinless valve plate by moving the clamping plate with a lever allows for faster clamping plate adjustment, improving the positioning efficiency of the pinless valve plate. Rotating the handle rotates the cam, pressing the bent plate to move. The bent plate moves outward, compressing the spring, which in turn moves the clamping plate outward, placing the pinless valve plate inside the clamping plate. Releasing the handle allows the compressed spring to return the bent plate to its original position, which in turn moves the clamping plate back to its original position, thus positioning the pinless valve plate. This method of fixing, instead of using a threaded rod to move the clamping plate, provides faster clamping plate adjustment and improved positioning efficiency. However, the above comparison document still has the following problems in actual use:

[0003] In actual use, it is inconvenient to change the clamping plate according to the size of the butterfly valve plate, resulting in poor adaptability. In addition, it is not possible to process quickly during use, resulting in poor work efficiency.

[0004] Based on this, a device that can quickly change the clamping plate according to the size of the butterfly valve plate and can be processed quickly is of great practicality. Utility Model Content

[0005] The purpose of this invention is to provide a device for rapid machining and positioning of the guide hole of the valve plate and valve shaft of a butterfly valve, in order to solve the above-mentioned technical problems.

[0006] This utility model provides a device for quick machining and positioning of the guide hole of the valve plate and valve shaft of a butterfly valve, including a support base, a quick replacement component, and a quick machining component.

[0007] The top of the support base is provided with a butterfly valve plate, and both sides of the butterfly valve plate are provided with clamping plates.

[0008] The quick-change assembly includes two sliding frames disposed on one side of the clamping plate. A fixed plate is slidably connected to one side of the two sliding frames. Two support plates are disposed on the top of the fixed plate. A hinge seat is disposed at one end of each of the two support plates. An auxiliary rod is hinged inside each of the two hinge seats. A moving bar is hinged in the middle of the two auxiliary rods. A fixed frame is disposed on one side of the moving bar. A fixed rod is inserted through the end of the fixed frame. Both ends of the fixed rod are fixedly connected to the sliding frame.

[0009] The rapid processing assembly includes two support platforms mounted on top of a support base. Each support platform has a rotating ring rotatably connected inside. Two synchronous motors are mounted on the bottom inner wall of each support platform. The output shafts of both synchronous motors pass through the support base and are fitted with worm gears. One end of each worm gear is engaged with a worm wheel. The interior of each worm wheel is fixedly connected to the rotating ring. A connecting plate is rotatably connected to the top of each worm gear, and one side of the connecting plate is fixedly connected to one of the support platforms.

[0010] Furthermore, the elastic drive assembly includes a fixing strip disposed on one side of the top of the fixing plate. Several auxiliary plates are disposed on one side of the fixing strip. Two limiting rods are disposed in the middle of the auxiliary plates. Moving blocks are slidably connected to the outer walls of the two limiting rods. First connecting seats are disposed on one side of each of the two moving blocks. Connecting rods are hinged inside the two first connecting seats. Second connecting seats are hinged to the ends of the two connecting rods. One side of each of the two second connecting seats is fixedly connected to an auxiliary rod. A spring is disposed at one end of each of the two moving blocks. The interior of each of the two springs is slidably connected to a limiting rod. One end of each of the two springs is fixedly connected to two of the auxiliary plates. Several damping rod springs are disposed on the other side of the moving strip. One side of each of the damping rod springs is fixedly connected to the fixing strip. A pull head is disposed in the middle of one side of the moving strip. A grip is disposed through the fixing strip on one side of the pull head.

[0011] Furthermore, each of the two rotating rings is equipped with an electric cylinder on one side, and the output shaft ends of the two electric cylinders are fixedly connected to the fixed plate through the rotating ring.

[0012] Furthermore, a base is provided at the bottom of the support.

[0013] Furthermore, the base has two support legs at its bottom.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) The movable bar allows the user to easily move it by manipulating the spring drive component. The movement of the movable bar will cause the fixed frame to slide out from the fixed rod, thereby releasing the limitation on the fixed rod. At this time, the user can hold the clamping plate and pull it upward, so that the clamping plate slides in the fixed plate through the sliding frame, and drives the fixed rod to move upward. The user can then remove the clamping plate and replace it with a clamping plate that matches the butterfly valve plate. After replacement, the user can reset and fix it by using the spring drive component, thereby achieving quick replacement of the clamping plate to adapt to butterfly valve plates of different sizes.

[0016] 2) The synchronous motor is conveniently turned on by the user through the controller, which drives the worm gear to rotate. The rotation of the worm gear will drive the worm wheel to rotate, which will drive the rotating ring to rotate, and then drive the internal parts to rotate. This will cause the clamping plate and the clamped butterfly valve plate to flip over, so as to quickly process the other side. The clamping plate that matches the butterfly valve plate can achieve rapid positioning, thereby realizing rapid processing and positioning by flipping. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figure 1 - Figure 4 A device for rapid machining and positioning of the guide hole of a butterfly valve plate and valve shaft includes a support base 100, a quick-change component 200, and a rapid machining component 300.

[0024] Please refer to the details. Figure 1 The top of the support base 100 is provided with a butterfly valve plate 110, and both sides of the butterfly valve plate 110 are provided with clamping plates 120.

[0025] Please see Figure 3 - Figure 4 The quick-change assembly 200 includes two sliding frames 210 disposed on one side of the clamping plate 120. A fixed plate 220 is slidably connected to one side of the two sliding frames 210. Two support plates 230 are disposed on the top of the fixed plate 220. A hinge seat 240 is disposed at one end of each of the two support plates 230. An auxiliary rod is hinged inside each of the two hinge seats 240. A moving bar 250 is hinged in the middle of the two auxiliary rods. A fixed frame 260 is disposed on one side of the moving bar 250. A fixed rod 270 is inserted through the end of the fixed frame 260. Both ends of the fixed rod 270 are fixedly connected to the sliding frame 210.

[0026] In one specific embodiment, the movable strip 250 allows the user to move it by manipulating the elastic drive assembly 400. The movement of the movable strip 250 will cause the fixed frame 260 to move, and the fixed frame 260 will slide out from the fixed rod 270, thereby releasing the limitation on the fixed rod 270. At this time, the user can hold the clamping plate 120 and pull it upward, so that the clamping plate 120 slides in the fixed plate 220 through the sliding frame 210, and drives the fixed rod 270 to move upward. The user can then remove the clamping plate 120 and replace it with a clamping plate 120 that matches the butterfly valve plate 110. After replacement, the user can reset and fix it by using the elastic drive assembly 400, thereby achieving quick replacement of the clamping plate 120 to adapt to different sizes of butterfly valve plates 110.

[0027] Please see Figure 2The rapid processing component 300 includes two support platforms 310 disposed on the top of the support base 100. A rotating ring 320 is rotatably connected inside each of the two support platforms 310. Two synchronous motors 330 are disposed on the bottom of the inner wall of the support platform 310. The output shaft ends of the two synchronous motors 330 are provided with worm gears 340 through the support base 100. One end of each worm gear 340 is engaged with a worm wheel 350. The interior of each worm wheel 350 is fixedly connected to the rotating ring 320.

[0028] In one specific embodiment, a synchronous motor 330 is provided, which can be easily turned on by the user via a controller. The synchronous motor 330 drives the worm gear 340 to rotate, which in turn drives the worm wheel 350 to rotate. The worm wheel 350 then drives the rotating ring 320 to rotate, which in turn drives the internal parts of the ring to rotate. This causes the clamping plate 120 and the clamped butterfly valve plate 110 to flip over, so that the other side can be processed quickly. Furthermore, the clamping plate 120, which matches the butterfly valve plate 110, can achieve rapid positioning, thereby achieving the purpose of flipping and rapid processing and positioning.

[0029] Please see Figure 4 The elastic drive assembly 400 includes a fixing strip 410 disposed on one side of the top of the fixing plate 220. A plurality of auxiliary plates 420 are disposed on one side of the fixing strip 410. Two limiting rods 430 are disposed in the middle of the plurality of auxiliary plates 420. Moving blocks are slidably connected to the outer walls of both limiting rods 430. A first connecting seat 440 is disposed on one side of each of the two moving blocks. Connecting rods 450 are hinged inside each of the two first connecting seats 440. Second connecting seats 460 are hinged to the ends of each of the two connecting rods 450. One side of the seat 460 is fixedly connected to the auxiliary rod. One end of each of the two moving blocks is provided with a spring 470. The interior of each of the two springs 470 is slidably connected to the limit rod 430. One end of each of the two springs 470 is fixedly connected to one of the two auxiliary plates 420. Several damping rod springs 480 are provided on the other side of the moving bar 250. One side of each of the several damping rod springs 480 is fixedly connected to the fixed bar 410. A pull head is provided in the middle of one side of the moving bar 250. A handle 490 is provided through the fixed bar 410 on one side of the pull head.

[0030] In one specific embodiment, the provided handle 490 facilitates the user's replacement of the clamping plate 120. The user grips and pulls the handle 490 to one side, causing it to move the moving bar 250 via a pull head. This movement of the moving bar 250, through a hinge, causes two auxiliary rods to rotate via the hinge seat 240. This rotation of the auxiliary rods causes the second connecting seat 460 to press against the first connecting seat 440 via the connecting rod 450, thus causing the first connecting seat 440 to move via the moving block. Sliding on the limiting rod 430 causes the spring 470 to contract under force, and the movement of the moving bar 250 also causes the damping rod spring 480 to contract under force. When the moving bar 250 drives the fixing bracket 260 to slide out from the fixing rod 270, after the user has replaced the clamping plate 120, he / she releases the grip handle 490, which resets the spring 470 and the damping rod spring 480, causing other parts to reset as well. Then, the fixing bracket 260 is re-clamped into the fixing rod 270 to limit its movement, thus achieving the purpose of quick replacement.

[0031] Please see Figure 1 An electric cylinder 500 is provided on one side of each of the two rotating rings 320, and the output shaft ends of the two electric cylinders 500 pass through the rotating rings 320 and are fixedly connected to the fixing plate 220.

[0032] In one specific embodiment, the electric cylinder 500 is provided so that the user can easily open the electric cylinder 500 through the controller, so that the electric cylinder 500 drives the fixing plate 220 and then the clamping plate 120 to clamp the butterfly valve plate 110, thereby achieving the purpose of quick clamping and positioning.

[0033] Please see Figure 1 The support 100 has a base 600 at its bottom.

[0034] In one specific embodiment, the base 600 facilitates the support and fixation of the top part during use, making the top part more stable during use and preventing wobbling.

[0035] Please see Figure 1 The base 600 has two support legs 700 at its bottom.

[0036] In one specific embodiment, the provided support leg 700 facilitates the overall support during use, thereby further increasing stability and improving overall stability.

[0037] Please see Figure 1 The base 600 and the support legs 700 are both made of titanium alloy, and the controller is located at the top corner of the base 600.

[0038] In one specific embodiment, the titanium alloy provided allows the base 600 and support leg 700 to be more stable during use by taking advantage of the titanium alloy's sturdy and durable properties, thus avoiding damage during use.

[0039] Please see Figure 1 - Figure 4 Both the synchronous motor 330 and the electric cylinder 500 are electrically connected to the controller, which is electrically connected to an external power supply.

[0040] In one specific embodiment, a controller is provided to facilitate power supply control of electrical equipment, ensuring that the equipment is powered on when needed, thus avoiding situations where power cannot be supplied when power is required.

[0041] In use, the user first uses the provided grip 490 to facilitate changing the clamping plate 120. By gripping and pulling the grip 490 to one side, the user moves the moving bar 250 via the pull head. The movement of the moving bar 250 causes the two auxiliary rods to rotate through the hinge seat 240. The rotation of the auxiliary rods causes the second connecting seat 460 to press the first connecting seat 440 through the connecting rod 450. This causes the first connecting seat 440 to slide on the limiting rod 430 via the moving block, thereby causing the spring 470 to contract under force. Then, the movement of the moving bar 250 also drives the damping rod spring. When the 480 is compressed by force, and the moving bar 250 drives the fixed frame 260 to slide out from the fixed rod 270, the user, after replacing the clamping plate 120, releases the grip 490, causing the spring 470 and damping rod spring 480 to reset, driving other parts to reset as well. This causes the fixed frame 260 to re-clamp into the fixed rod 270 for limiting its position, achieving the purpose of quick replacement. Furthermore, the provided moving bar 250 allows the user to easily move it by manipulating the elastic drive assembly 400. The movement of the moving bar 250 will drive the fixed frame 260 to move, causing it to slide out from the fixed rod 270. The clamping plate 120 slides out, releasing the limit on the fixed rod 270. At this point, the user can grasp the clamping plate 120 and pull it upwards, causing the clamping plate 120 to slide within the fixed plate 220 via the sliding frame 210, thus moving the fixed rod 270 upwards. The user can then remove and replace the clamping plate 120 with one that matches the butterfly valve plate 110. After replacement, the user can reset and fix it using the spring drive assembly 400, thereby achieving quick replacement of the clamping plate 120 to accommodate butterfly valve plates 110 of different sizes. Finally, the provided synchronous motor 330 allows the user to easily activate it via the controller. 330, the synchronous motor 330 drives the worm gear 340 to rotate, the worm gear 340 rotates, the worm wheel 350 rotates, the worm wheel 350 rotates, the rotating ring 320 rotates, and then drives the internal parts to rotate, causing the clamping plate 120 and the clamped butterfly valve plate 110 to flip, so as to quickly process the other side. The clamping plate 120 matched with the butterfly valve plate 110 can achieve rapid positioning, thereby achieving the purpose of flipping and rapid processing and positioning. It should be noted that "the butterfly valve plate 110 is vertically clamped in the figure. It can be changed to horizontal clamping of the butterfly valve plate 110 by replacing the clamping plate 120, so as to achieve efficient use."

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
