DETAILED DESCRIPTION

[0042] 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.

[0043] The embodiment of the present invention provides a grinding device for butterfly valve body processing, including a support base 1. For example, Figure 1 and Figure 2 As shown, two groups of positioning plates 2 are symmetrically provided at the two side edges of the top of the support base 1; a mounting plate 3 is provided at one side edge of the top of the support base 1; two groups of splash shields 7 are symmetrically provided on the two side walls of the mounting plate 3; a mechanical arm 5 is provided at the edge of the top of the support base 1 away from the mounting plate 3; a transmission connection limiting mechanism 6 is provided on the output end of the mechanical arm 5; an adjustable grinding mechanism 4 is provided on one side wall of the mounting plate 3 close to the mechanical arm 5; two groups of detection mechanisms 8 are symmetrically provided on the side walls opposite to the two groups of splash shields 7; a water tank 10 is provided in the support base 1; a water pump 17 is provided on one side wall of the mounting plate 3 away from the mechanical 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 The polishing mechanism 4 is connected; a filtering groove 11 is provided on the top of the water tank 10; the filtering groove 11 is located between the two groups of splash shields 7; two groups of driving rollers 12 are symmetrically provided at the edges of the top two sides of the water tank 10; a filtering belt 9 is provided below the filtering groove 11; the filtering belt 9 is sleeved on the outer walls of the two groups of driving rollers 12; a waste collecting chamber 13 is provided in the supporting base 1; a waste collecting box 16 is movably penetrated on the inner wall of the waste collecting chamber 13 on the side away from the water tank 10; a collecting groove 14 is provided on the inner wall of the waste collecting chamber 13 on the side close to the water tank 10; a scraper 15 is provided in the collecting groove 14; one end of the scraper 15 extends to the top of the waste collecting box 16, and the other end movably contacts the outer wall of the filtering belt 9.

[0044] When polishing the butterfly valve body, first place the butterfly valve body on one of the positioning and placement plates 2, then the robot arm 5 automatically positions the butterfly valve body and drives the limiting mechanism 6 to fix the butterfly valve body, and then the robot arm 5 drives the butterfly valve body to be transferred to the adjustable polishing mechanism 4 through the limiting mechanism 6 for polishing. After the polishing work is completed, the two groups of detection mechanisms 8 will scan the appearance of the polished butterfly valve body, further optimize the polishing of the defective areas, and then place the polished butterfly valve body on another group of positioning and placement plates 2. During the grinding process, the water pump 17 will draw water from the water tank 10 and then spray it to the grinding area through the adjustable grinding mechanism 4 to prevent valve body debris from floating into the air. Then the water will fall on the filter belt 9 with the debris, and the water will re-enter the water tank 10 through the filter belt 9, while the debris will be scraped off by the scraper 15 as the filter belt 9 rotates and is drawn into the waste collection box 16. This not only realizes the recycling of water, but also prevents the valve body debris from floating into the air and causing damage to the staff, thereby improving the safety of the grinding device.

[0045] For example, Figure 3 and Figure 4 As shown, the adjustable grinding mechanism 4 includes a first shell 401; a plurality of groups of adjustment slots 402 are evenly spaced on one side wall of the first shell 401; two groups of grinding components 403 are symmetrically arranged in each group of the adjustment slots 402; a plurality of groups of hose reels 404 are symmetrically and evenly spaced on the top and bottom of the first shell 401; each group of the hose reels 404 is connected to a corresponding group of grinding components 403; an adjustment cavity 405 is opened in the first shell 401; a plurality of groups of adjustment motors 406 are evenly spaced on the top of the adjustment cavity 405; a group of first screw rods 407 are transmission-connected to the output end of each group of the adjustment motors 406; a first screw rod 407 of each group is transmission-connected to the end away from the adjustment motor 406 A second screw rod 408 is provided in each group; one end of each group of the second screw rods 408 away from the first screw rod 407 is rotatably connected to the bottom inner wall of the adjusting chamber 405; the central axis of each group of the second screw rods 408 is on the same straight line as the central axis of the corresponding group of the first screw rods 407; the thread direction of each group of the second screw rods 408 is opposite to the thread direction of the corresponding group of the first screw rods 407; a plurality of groups of sliders 409 are slidably connected to the inner wall of the adjusting chamber 405 on one side away from the adjusting groove 402; each group of the first screw rods 407 is threadedly connected to a corresponding group of sliders 409; each group of the second screw rods 408 is threadedly connected to a corresponding group of sliders 409; each group of the sliders 409 is transmission connected to a corresponding group of grinding components 403.

[0046] When grinding the butterfly valve body, first control the robot arm 5 to drive the butterfly valve body to transfer between several groups of grinding components 403 of the adjustable grinding mechanism 4, and then control the corresponding adjusting motor 406 to drive the corresponding first screw rod 407 and the second screw rod 408 to rotate, and under the threaded connection relationship between the slider 409 and the first screw rod 407 and the second screw rod 408, the corresponding slider 409 drives the corresponding grinding component 403 to contact the outer wall of the butterfly valve body, and then control the corresponding grinding component 403 to start, and then control the robot arm 5 to drive the butterfly valve body to reciprocate, so that several groups of grinding components can synchronously grind the outer wall of the butterfly valve body, avoiding the problem of small contact area between the grinding component 403 and the butterfly valve body and slow grinding speed, thereby improving the working efficiency of the grinding device.

[0047] For example, Figure 5 As shown, the grinding assembly includes a motor box 40301; a water supply pipe 40302 is provided on one side wall of the motor box 40301; the water supply pipe 40302 is connected to the output end of the water pump 17; a grinding rod 40305 is connected to the output end of the motor box 40301; a water guide cavity 40306 is provided in the grinding rod 40305; a plurality of water outlet holes 40307 are evenly distributed on the inner wall of the water guide cavity 40306; a water supply pipe 40302 is connected to the output end of the water pump 17; a grinding rod 40305 is connected to the output end of the motor box 40301; a water guide cavity 40306 is provided in the grinding rod 40305; a plurality of water outlet holes 40307 are evenly distributed on the inner wall of the water guide cavity 40306; a plurality of water outlet holes 40307 are evenly distributed on the inner wall of the water supply pipe 40302 ... There is a water guide ring 40303; the water guide ring 40303 is rotatably connected to the grinding rod 40305; a plurality of first water guide holes 40304 are arranged in a circular array on a side wall of the water guide ring 40303 close to the grinding rod 40305; a plurality of second water guide holes 40308 are arranged in a circular array on an inner wall of a side of the water guide cavity 40306 close to the water guide ring 40303; the spacing between two adjacent groups of the second water guide holes 40308 is smaller than the inner diameter of the first water guide hole 40304.

[0048] When the butterfly valve body is being polished, the water pump 17 draws water from the water tank 10 and then enters the water guide cavity 40306 of the polishing rod 40305 through the water supply pipe 40302 and the water guide ring 40303 in turn, and then overflows from a plurality of water outlet holes 40307. Since the spacing between two adjacent groups of second water guide holes 40308 is smaller than the inner diameter of the first water guide hole 40304, the transmission of water will not affect the rotation of the polishing rod 40305, which not only achieves rapid cooling of the polishing rod 40305, but also prevents valve body debris from floating into the air and causing damage to the staff.

[0049] For example, Figure 6 and Figure 7As shown, the limiting mechanism 6 includes a support column 601; a positioning camera 603 is provided at one end of the support column 601 away from the robotic arm 5; a plurality of groups of electric push rods 602 are evenly spaced in a circular array on the outer wall of the support column 601; one end of each group of electric push rods 602 away from the support column 601 is transmission-connected to a group of limiting blocks 604; the top-view cross-section of each group of limiting blocks 604 is semicircular; a plurality of groups of anti-slip grooves 605 are evenly spaced on one side wall of each group of limiting blocks 604 away from the support column 601; a group of distance sensors 606 are provided at one end of each group of limiting blocks 604 away from the support column 601.

[0050] When polishing the butterfly valve body, first place the butterfly valve body on the corresponding positioning plate 2, then the robotic arm 5 will drive the limiting mechanism 6 to move above the positioning plate 2, and then the positioning camera 603 will scan the butterfly valve body to confirm the center cavity position, and then control the robotic arm 5 to drive the limiting mechanism 6 to enter the cavity of the butterfly valve body, and then several groups of distance sensors 606 will 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 contact the inner wall of the butterfly valve body, so as to fix the butterfly valve body and avoid the problem of grinding blind spots during external clamping.

[0051] For example, Figure 8 and Fig. 9 As shown, the detection mechanism 8 includes a second shell 801; an installation cavity 806 is provided in the second shell 801; an opening is provided on the inner wall of one side of the installation cavity 806; a splash-proof glass plate 803 is provided on the opening; a detection camera 802 is provided on the inner wall of the installation cavity 806 away from the opening; two groups of electric slides 804 are symmetrically provided at the edges of both sides of the wall of the splash-proof glass plate 803 away from the detection camera 802; cleaning brushes 805 are transmission-connected to the output ends of the two groups of electric slides 804; the bristles of the cleaning brush 805 are movably in contact with a side wall of the splash-proof glass plate 803.

[0052] After the grinding of the butterfly valve body is completed, the control robot arm 5 drives the butterfly valve body to rotate between the two sets of detection mechanisms 8, and the two sets of detection cameras 802 are used to detect whether there are defects in the grinding of the outer wall of the butterfly valve body. If there are defects, the butterfly valve body is controlled to be further optimized and polished to ensure the grinding quality. During the grinding process of the butterfly valve body, water will carry valve body debris to the splash-proof glass plate 803. When the detection camera 802 detects it and controls the two sets of electric slides 804 to drive the cleaning brush 805 to clean the splash-proof glass plate 803, errors in valve body detection can be avoided.

[0053] By controlling the robot arm 5 to drive the butterfly valve body to transfer between several groups of grinding components 403 of the adjustable grinding mechanism 4, and then controlling the corresponding grinding component 403 to press against the outer wall of the butterfly valve body, and then starting the corresponding grinding component 403, the robot arm 5 is controlled to drive the butterfly valve body to reciprocate, and at the same time, the grinding component 403 will automatically discharge water to cool down and prevent debris from flying, so that several groups of grinding components can synchronously grind the outer wall of the butterfly valve body, avoiding the problem of small contact area between the grinding mechanism and the butterfly valve body and slow grinding speed, and improving the working efficiency of the grinding device.

[0054] By controlling the robot arm 5 to drive the limit mechanism 6 to move to the top of the positioning placement plate 2, and then the positioning camera 603 scans the butterfly valve body to confirm the central cavity position, and then the robot arm 5 is controlled to drive the limit mechanism 6 to enter the cavity of the butterfly valve body, and then several groups of distance sensors 606 detect the distance between the corresponding limit block 604 and the inner wall of the butterfly valve body, and control the corresponding electric push rod 602 to drive the limit block 604 to contact the inner wall of the butterfly valve body, so as to fix 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 the water pump 17 to extract water from the water tank 10 and then spraying it to the grinding area through the adjustable grinding mechanism 4, the valve body debris is prevented from being scattered into the air. Then the water will carry the valve body debris and fall on the filter belt 9. The water flows through the filter belt 9 and re-enters the water tank 10. The filter belt 9 will move with the valve body debris until the debris is scraped off by the scraper 15 and entered into the waste collection box 16. This not only realizes the recycling of water, but also prevents the valve body debris from being scattered into the air and causing damage to the staff, thereby improving the safety of the grinding device.

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