[0014] The valve body appearance defect detection device for valve body production and processing has the advantages that: the auxiliary structure can be used for rotating detection of the valve body, so that the valve body is more convenient to detect, and the rotating centrifugal force can be used for clamping the valve body during rotation, so that the valve body is more stable during rotation, and the blowing structure can be used to drive the fan blades to rotate to generate wind power to blow dust on the surface of the valve body without an additional power source; When the appearance defect of the sample valve body is detected, the valve body is first placed in the limiting groove at the top end of the mounting sleeve, and the limiting groove is used to preliminarily limit the position of the valve body, so that the position of the valve body does not deviate during initial rotation, thereby completing the preliminary limiting work. Further, when the valve body is placed, the motor drives the connecting disc to rotate, and the mounting sleeve is driven to rotate by the rotation of the connecting disc, and the valve body is driven to rotate by the rotation of the mounting sleeve, and the industrial camera is started to work during rotation, so that the different surfaces of the valve body can pass in front of the industrial camera in turn, so that the industrial camera can detect the appearance of the valve body without setting multiple industrial cameras, thereby reducing the cost. Further, when the mounting sleeve rotates, centrifugal force is generated, and the sliding block moves at the top end of the clamping seat under the action of the centrifugal force. When the sliding block moves, the side of the extrusion block is provided with an inclined angle, so that the extrusion block is pressed to move upward when the sliding block contacts the bottom end of the extrusion block. The extrusion block moves upward to push the clamping block upward, so that the extrusion block is pushed out from the inside of the moving groove and attached to the outside of the bottom end of the valve body. Multiple extrusion blocks are used to clamp the bottom end of the valve body from multiple directions, so that the clamping effect is better and more stable, thereby completing the clamping work, so that the position of the valve body does not deviate during rotation, thereby affecting the detection effect. Further, the clamping structure utilizes the centrifugal force of rotation to convert the centrifugal force of the sliding block into upward clamping force of the extrusion block, which ensures reliable clamping and does not block the appearance detection area of the valve body. This clamping method does not need manual operation, so that the clamping is more convenient, and during the appearance defect detection, the clamping work of the mounting sleeve does not stop as long as the mounting sleeve is rotating, and when the valve body detection is completed, the sliding block is pulled back to the original position under the action of the return spring, so that the extrusion block falls to complete the clamping and falling work, thereby facilitating the detection work of the next group of valve bodies. Further, when the slider moves at the top end of the clamping seat, the two sides of the slider slide in the inner part of the sliding groove, and whenever the two sides of the slider pass the position of the fixed head, the clamping seat is pressed to move inward by a part, thereby opening the oil outlet, making the lubricating oil in the oil cavity flow out, lubricating the sliding groove, reducing the friction between the slider and the sliding groove, thereby completing the work of reducing the friction; By setting the blowing structure, when the valve body is clamped and rotated, the mounting sleeve drives the fixed sleeve to rotate, and the fixed sleeve makes the gear at the bottom end of the fan blade contact with the gear ring in the rotating process, so that the fan blade is driven to rotate through the meshing between the gear and the gear ring, and the flowing air is sprayed out through the blowing head in the rotating process of the fan blade, so that the dust on the surface of the valve body is cleaned, and the dust is prevented from being left on the surface of the valve body, so that the effect of detection of the industrial camera is affected due to the dust when working, thereby completing the dust removal work.

[0020] Specifically, in this embodiment, when the appearance defect detection of the valve body 5 is carried out, first, the valve body 5 is placed into the limiting groove 10 at the top end of the mounting sleeve 8. At this time, the use of the limiting groove 10 can preliminarily limit the position of the valve body 5. After the valve body 5 is placed, the external power source starts the motor 701. After starting, the motor 701 drives the connecting disc 702 to rotate, and the connecting disc 702 drives the mounting sleeve 8 to rotate in the process of rotating. The mounting sleeve 8 drives the valve body 5 to rotate. When the valve body 5 rotates, the industrial camera 6 is started to work. At this time, the rotating valve body 5 can make different surfaces of the valve body 5 pass in front of the industrial camera 6 in turn, so that the industrial camera 6 can detect the appearance of the valve body 5 without needing to be provided with multiple industrial cameras 6 to detect the appearance of all surfaces of the valve body 5, thereby reducing the use cost during detection. When the mounting sleeve 8 rotates, a centrifugal force is generated. Under the action of the centrifugal force, the sliding block 707 moves to one side at the top end of the clamping seat 703. When the sliding block 707 moves to one side, the return spring 706 is deformed. When the sliding block 707 moves, because one side of the extrusion block 708 is provided with an inclined angle, when the sliding block 707 contacts the extrusion block 708, the extrusion block 708 is pressed to move upward. When the extrusion block 708 moves upward, the clamping block 709 is pushed to move upward, so that the clamping block 709 is ejected from the inside of the moving slot 11. Through the use of multiple extrusion blocks 708, the bottom end of the valve body 5 can be clamped in multiple directions to complete the clamping of the valve body 5, so that the valve body 5 does not move during detection, preventing the movement of the valve body 5 from affecting the detection effect. Moreover, the clamping is achieved by using the centrifugal force of rotation, so that the centrifugal force of the sliding block 707 is converted into the upward clamping force of the extrusion block 708, which ensures the reliability of clamping and does not block the appearance detection area of the valve body 5. This clamping method does not need manual operation, so that clamping is more convenient. Moreover, during the appearance defect detection, as long as the mounting sleeve 8 is rotating, the clamping work will not stop. After the valve body 5 is detected, under the action of the return spring 706, the sliding block 707 is pulled back to the original position, so that the extrusion block 708 falls to complete the clamping and falling work, facilitating the detection of the next valve body 5. Moreover, when the sliding block 707 moves at the top end of the clamping seat 703, the two sides of the sliding block 707 slide in the sliding slot 704. Whenever the two sides of the sliding block 707 pass the position of the fixed head 7013, the fixed head 7013 is pressed to move inward, so that the oil outlet 7012 is opened, the lubricating oil in the oil cavity 7011 flows out, the sliding slot 704 is lubricated, the friction between the sliding block 707 and the sliding slot 704 is reduced, and the effect of reducing the friction is achieved. When the sliding block 707 moves away from the position of the fixed head 7013, under the action of the extension spring 7014, the fixed head 7013 returns to the original position, and the oil outlet 7012 is blocked, so that the sliding slot 704 is lubricated in a timely manner.
[0021] See Figures 1-9 A movable component 3 is installed on one side of the top of the workbench 1. An industrial camera 6 is installed on one side of the movable component 3. A control panel 2 is installed on one side of the movable component 3. A blowing structure 9 is provided inside the mounting sleeve 8. The blowing structure 9 includes a gear ring 902, which is installed on the top of the workbench 1 at the bottom of the mounting sleeve 8. A fixing sleeve 903 is installed inside the mounting sleeve 8. A fixing frame 907 is fixed inside the fixing sleeve 903. A fan blade 904 is installed on the top of the fixing frame 907. A gear 905 is installed on the bottom of the fan blade 904. An air inlet 906 is opened inside the fixing seat 4 at the bottom of the gear 905. A blower head 901 is installed on the top of the fan blade 904. Multiple sets of blower heads 901 are provided, and the multiple sets of blower heads 901 are arranged in a ring at the top of the mounting sleeve 8. Multiple sets of gears 905 are provided, and the multiple sets of gears 905 mesh with the gear ring 902.
[0022] Specifically, in this embodiment, when the valve body 5 rotates, the mounting sleeve 8 drives the fixed sleeve 903 to rotate. During the rotation of the fixed sleeve 903, the gear 905 at the bottom of the fan blade 904 comes into contact with the gear ring 902. Through the meshing between the gear 905 and the gear ring 902, the fan blade 904 is driven to rotate. During the rotation of the fan blade 904, airflow is generated, and the flowing air is sprayed out through the blower head 901 to clean the dust on the surface of the valve body 5, preventing dust from remaining on the surface of the valve body 5 and causing the industrial camera 6 to be affected by dust during operation. This completes the dust removal work. When the industrial camera 6 is performing inspection, it uploads the captured data to the terminal for analysis, thereby detecting defects in the appearance of the valve body 5, and finally completing the inspection of defects on the outside of the valve body 5.
