Description

Technical Field

[0001] This invention belongs to the field of butterfly valve manufacturing technology, and specifically relates to a grinding device for processing butterfly valve bodies and its operating method. Background Technology

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve that can be used for on / off control of low-pressure pipeline media. A butterfly valve is a type of valve in which the closing element (valve disc or butterfly plate) is a disc that rotates around the valve shaft to achieve opening and closing.

[0003] A search revealed that Chinese Patent Publication No. CN219234901U, published on June 23, 2023, discloses a butterfly valve housing grinding mechanism, belonging to the field of butterfly valve manufacturing technology. This butterfly valve housing grinding mechanism includes a support assembly and a grinding assembly.

The support section includes a load-bearing frame and casters, with the casters disposed on the lower surface of the load-bearing frame. The dustproof section includes a dustproof plate, a sliding door, and a handle. The dustproof plate is disposed on the load-bearing frame, the sliding door is slidably disposed on the dustproof plate, and the handle is fixed to the outer wall of the sliding door.

[0018] A method for operating a grinding equipment used in the machining of butterfly valve bodies, the method comprising:

[0019] Place the butterfly valve body on top of the positioning plate;

[0020] The robotic arm drives the limit mechanism to fix the valve body;

[0021] The robotic arm is controlled to move the valve body to the middle of several grinding components;

[0022] Control the corresponding grinding components to contact the outer wall of the valve body;

[0023] The corresponding grinding components are activated to grind the outer wall of the valve body;

[0024] Complete the grinding work on the butterfly valve body.

[0025] The beneficial effects of this invention are:

[0026] 1. By controlling the robotic arm to move the butterfly valve body to several sets of grinding components of the adjustable grinding mechanism, the corresponding grinding components are then controlled to abut against the outer wall of the butterfly valve body. The corresponding grinding components are then activated, and the robotic arm is controlled to drive the butterfly valve body to reciprocate. At the same time, the grinding components automatically discharge water to cool down and prevent debris from scattering. This allows several sets of grinding components to grind the outer wall of the butterfly valve body simultaneously, avoiding the problem of small contact area between the grinding mechanism and the butterfly valve body and slow grinding speed, thus improving the working efficiency of the grinding device.

[0027] 2. By controlling the robotic arm to move the limiting mechanism above the positioning plate, the positioning camera scans the butterfly valve body to confirm the position of the central cavity. Then, the robotic arm is controlled to move the limiting mechanism into the cavity of the butterfly valve body. Several sets of distance sensors detect the distance between the corresponding limiting block and the inner wall of the butterfly valve body, and control the corresponding electric push rod to move the limiting block against the inner wall of the butterfly valve body, thereby fixing the butterfly valve body. Fixing the butterfly valve body from the inside avoids the problem of grinding blind spots when clamping from the outside, and improves the grinding effect of the grinding device.

[0028] 3. By using a water pump to draw water from the tank and then spraying it onto the grinding area through an adjustable grinding mechanism, valve body debris is prevented from scattering into the air. The water then carries the valve body debris onto the filter belt, and the water flows back into the tank through the filter belt. The filter belt carries the valve body debris until it is scraped off by a scraper and falls into the waste collection box. This not only achieves water recycling but also prevents valve body debris from scattering into the air and causing harm to workers, thus improving the safety of the grinding device.

[0029] 4. By controlling the robotic arm to rotate the butterfly valve body between two sets of detection mechanisms, two sets of detection cameras are used to detect whether there are any defects in the outer wall grinding of the butterfly valve body. During the grinding process, water will carry valve body debris onto the splash-proof glass plate. The detection cameras will detect this and control two sets of electric slides to drive cleaning brushes to clean the splash-proof glass plate, avoiding errors in valve body detection. When the two sets of detection cameras detect defects on the outer wall of the valve body, they will control the robotic arm to drive the butterfly valve body for optimized grinding, improving the working quality of the grinding device.

[0042] 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.

[0043] This invention provides a grinding device for machining butterfly valve bodies, including a support base 1. For example, as shown... Figure 1 and Figure 2 As shown, two sets of positioning plates 2 are symmetrically arranged on the top two sides of the support base 1; an mounting plate 3 is provided on one side of the top of the support base 1; two sets of splash guards 7 are symmetrically arranged on the two side walls of the mounting plate 3; a robotic arm 5 is provided on the top side of the support base 1 away from the mounting plate 3; a limit mechanism 6 is connected to the output end of the robotic arm 5; an adjustable grinding mechanism 4 is provided on the side wall of the mounting plate 3 near the robotic arm 5; two sets of detection mechanisms 8 are symmetrically arranged on the opposite side walls of the two sets of splash guards 7; a water tank 10 is provided inside the support base 1; a water pump 17 is provided on the side wall of the mounting plate 3 away from the robotic arm 5; the input end of the water pump 17 is connected to the bottom of the water tank 10, and the output end is connected to the adjustable grinding mechanism 4. The grinding mechanism 4 is connected; a filter channel 11 is provided on the top of the water tank 10; the filter channel 11 is located between two sets of anti-splash baffles 7; two sets of transmission rollers 12 are symmetrically arranged on both sides of the top of the water tank 10; a filter belt 9 is provided below the filter channel 11; the filter belt 9 is sleeved on the outer wall of the two sets of transmission rollers 12; a waste collection chamber 13 is provided in the support base 1; a waste collection box 16 is movably inserted through the inner wall of the waste collection chamber 13 on the side away from the water tank 10; a collection channel 14 is provided on the inner wall of the waste collection chamber 13 on the side close to the water tank 10; a scraper 15 is provided in the collection channel 14; one end of the scraper 15 extends above the waste collection box 16, and the other end movably abuts against the outer wall of the filter belt 9.

[0044] When polishing the butterfly valve body, the butterfly valve body is first placed on one of the positioning plates 2. Then, the robotic arm 5 automatically positions the butterfly valve body and drives the limiting mechanism 6 to fix the butterfly valve body. Then, the robotic arm 5 drives the butterfly valve body to the adjustable polishing mechanism 4 through the limiting mechanism 6 for polishing. After the polishing is completed, the two sets of detection mechanisms 8 will perform an appearance scan on the polished butterfly valve body, further optimize and polish any flawed areas, and then place the polished butterfly valve body on another positioning plate 2. During the polishing process, the water pump 17 draws water from the water tank 10 and sprays it onto the polishing area through the adjustable polishing mechanism 4, preventing valve body debris from scattering into the air. The water then carries the debris onto the filter belt 9, and the water flows back into the water tank 10 through the filter belt 9. The debris is scraped off by the scraper 15 and drawn into the waste collection box 16 as the filter belt 9 rotates. This not only achieves water recycling but also prevents valve body debris from scattering into the air and causing harm to the workers, thus improving the safety of the polishing device.

[0045] For example, such as Figure 3 and Figure 4 As shown, the adjustable polishing mechanism 4 includes a first housing 401; a plurality of sets of adjustment slots 402 are equally spaced on one side wall of the first housing 401; two sets of polishing components 403 are symmetrically arranged in each set of adjustment slots 402; a plurality of sets of tube retractors 404 are symmetrically and equally spaced on the top and bottom of the first housing 401; each set of tube retractors 404 is connected to a corresponding set of polishing components 403; an adjustment cavity 405 is opened in the first housing 401; a plurality of sets of adjustment motors 406 are equally spaced on the top of the adjustment cavity 405; a set of first lead screws 407 are drivenly connected to the output end of each set of adjustment motors 406; and a set of first lead screws 407 are drivenly connected to the end of each set of first lead screws 407 away from the adjustment motors 406. A second lead screw 408 is provided; the end of each second lead screw 408 away from the first lead screw 407 is rotatably connected to the bottom inner wall of the adjusting cavity 405; the central axis of each second lead screw 408 is on the same straight line as the central axis of the corresponding first lead screw 407; the thread direction of each second lead screw 408 is opposite to the thread direction of the corresponding first lead screw 407; several sets of sliders 409 are slidably connected to the inner wall of the adjusting cavity 405 away from the adjusting groove 402; each first lead screw 407 is threadedly connected to a corresponding set of sliders 409; each second lead screw 408 is threadedly connected to a corresponding set of sliders 409; each set of sliders 409 is drive-connected to a corresponding set of grinding components 403.

[0046] When polishing the butterfly valve body, the robotic arm 5 is first controlled to move the butterfly valve body between several sets of polishing components 403 of the adjustable polishing mechanism 4. Then, the corresponding adjusting motor 406 is controlled to drive the corresponding first lead screw 407 and second lead screw 408 to rotate. With the threaded connection between the slider 409 and the first lead screw 407 and second lead screw 408, the corresponding slider 409 drives the corresponding polishing component 403 to abut against the outer wall of the butterfly valve body. Then, the corresponding polishing component 403 is started, and the robotic arm 5 is controlled to drive the butterfly valve body to reciprocate. This allows several sets of polishing components to polish the outer wall of the butterfly valve body simultaneously, avoiding the problem of small contact area and slow polishing speed between the polishing component 403 and the butterfly valve body, and improving the working efficiency of the polishing device.

[0047] For example, such as Figure 5 As shown, the grinding assembly includes a motor housing 40301; a water supply pipe 40302 is provided on one side wall of the motor housing 40301; the water supply pipe 40302 is connected to the output end of the water pump 17; a grinding rod 40305 is drivenly connected to the output end of the motor housing 40301; a water guiding cavity 40306 is provided inside the grinding rod 40305; several sets of water outlet holes 40307 are evenly distributed on the inner wall of the water guiding cavity 40306; the side wall of the water supply pipe 40302 is connected to... A water guiding ring 40303 is provided; the water guiding ring 40303 is rotatably connected to the polishing rod 40305; a number of first water guiding holes 40304 are arranged in a ring array on the side wall of the water guiding ring 40303 near the polishing rod 40305; a number of second water guiding holes 40308 are arranged in a ring array on the inner wall of the water guiding cavity 40306 near the water guiding ring 40303; the distance between two adjacent groups of second water guiding holes 40308 is smaller than the inner diameter of the first water guiding holes 40304.

[0048] During the polishing of the butterfly valve body, the water pump 17 draws water from the water tank 10 and then sequentially enters the water guide cavity 40306 of the polishing rod 40305 through the water supply pipe 40302 and the water guide ring 40303. The water then overflows from several sets of water outlet holes 40307. Since the distance between two adjacent sets of second water guide holes 40308 is smaller than the inner diameter of the first water guide hole 40304, the water transmission will not affect the rotation of the polishing rod 40305. This not only achieves rapid cooling of the polishing rod 40305, but also prevents valve body debris from being scattered into the air and causing harm to the workers.

[0049] For example, such as Figure 6 and Figure 7As shown, the limiting mechanism 6 includes a support column 601; a positioning camera 603 is provided at the end of the support column 601 away from the robotic arm 5; several sets of electric push rods 602 are arranged in a circular array at equal intervals on the outer wall of the support column 601; a set of limiting blocks 604 are driven to the end of each set of electric push rods 602 away from the support column 601; the top view cross section of each set of limiting blocks 604 is semi-circular; several sets of anti-slip grooves 605 are equally spaced on the side wall of each set of limiting blocks 604 away from the support column 601; a set of distance sensors 606 is provided at the end of each set of limiting blocks 604 away from the support column 601.

[0050] When grinding the butterfly valve body, the butterfly valve body is first placed on the corresponding positioning plate 2. Then, the robotic arm 5 drives the limiting mechanism 6 to move above the positioning plate 2. The positioning camera 603 scans the butterfly valve body to confirm the position of the central cavity. Then, the robotic arm 5 is controlled to drive the limiting mechanism 6 into the cavity of the butterfly valve body. Then, several sets of distance sensors 606 detect the distance between the corresponding limiting block 604 and the inner wall of the butterfly valve body, and control the corresponding electric push rod 602 to drive the limiting block 604 to abut against the inner wall of the butterfly valve body, thereby fixing the butterfly valve body and avoiding the problem of grinding blind spots when externally clamped.

[0051] For example, such as Figure 8 and Figure 9 As shown, the detection mechanism 8 includes a second housing 801; the second housing 801 has a mounting cavity 806; an opening is provided on one side inner wall of the mounting cavity 806; a splash-proof glass plate 803 is provided on the opening; a detection camera 802 is provided on the side inner wall of the mounting cavity 806 away from the opening; two sets of electric slides 804 are symmetrically arranged on both sides of the side wall of the splash-proof glass plate 803 away from the detection camera 802; cleaning brushes 805 are connected to the output ends of the two sets of electric slides 804; the bristles of the cleaning brushes 805 move and abut against one side wall of the splash-proof glass plate 803.

[0052] After the butterfly valve body is polished, the control robotic arm 5 drives the butterfly valve body to rotate between two sets of detection mechanisms 8. Two sets of detection cameras 802 detect whether there are any defects in the polishing of the outer wall of the butterfly valve body. If defects are found, the control system further optimizes the polishing of the butterfly valve body to ensure polishing quality. During the polishing process, water will carry valve body debris onto the splash-proof glass plate 803. When the detection camera 802 detects this, it will control two sets of electric sliding tables 804 to drive the cleaning brush 805 to clean the splash-proof glass plate 803, thus avoiding errors in valve body detection.

[0053] By controlling the robotic arm 5 to move the butterfly valve body between several sets of grinding components 403 of the adjustable grinding mechanism 4, the corresponding grinding components 403 are then controlled to abut against the outer wall of the butterfly valve body. The corresponding grinding components 403 are then activated, and the robotic arm 5 is controlled to drive the butterfly valve body to reciprocate. At the same time, the grinding components 403 automatically discharge water to cool down and prevent debris from scattering, so that several sets of grinding components can simultaneously grind the outer wall of the butterfly valve body. This avoids the problem of small contact area between the grinding mechanism and the butterfly valve body and slow grinding speed, and improves the working efficiency of the grinding device.

[0054] By controlling the robotic arm 5 to move the limiting mechanism 6 above the positioning plate 2, the positioning camera 603 scans the butterfly valve body to confirm the position of the central cavity. Then, the robotic arm 5 is controlled to move the limiting mechanism 6 into the cavity of the butterfly valve body. Several sets of distance sensors 606 detect the distance between the corresponding limiting block 604 and the inner wall of the butterfly valve body, and control the corresponding electric push rod 602 to move the limiting block 604 to abut against the inner wall of the butterfly valve body, thereby fixing the butterfly valve body. Fixing the butterfly valve body from the inside avoids the problem of grinding blind spots when clamped externally, and improves the grinding effect of the grinding device.

[0055] By using water pump 17 to draw water from water tank 10 and then spraying it onto the grinding area through adjustable grinding mechanism 4, valve body debris is prevented from scattering into the air. The water then carries the valve body debris onto filter belt 9, and the water flows back into water tank 10 through filter belt 9. Filter belt 9 carries the valve body debris until the debris is scraped off by scraper 15 and swept into waste collection box 16. This not only achieves water recycling but also prevents valve body debris from scattering into the air and causing harm to workers, thus improving the safety of the grinding device.

[0056] By controlling the robotic arm 5 to rotate the butterfly valve body between two sets of detection mechanisms 8, two sets of detection cameras 802 are used to detect whether there are any defects in the outer wall grinding of the butterfly valve body. During the grinding process, water will carry valve body debris onto the splash-proof glass plate 803. The detection cameras 802 will detect and control the two sets of electric slides 804 to drive the cleaning brush 805 to clean the splash-proof glass plate 803, avoiding errors in valve body detection. When the two sets of detection cameras 802 detect defects on the outer wall of the valve body, they will control the robotic arm 5 to drive the butterfly valve body for optimized grinding, improving the working quality of the grinding device.

[0058] Place the butterfly valve body on top of the positioning plate;

[0059] The robotic arm drives the limit mechanism to fix the valve body;
