[0023] See also Figure 1-5The present invention provides a technical solution: an assembly detection device for piston processing, comprising a detection device body 1 and a visual detection camera 8, an assembly platform 2 is provided on the detection device body 1, and a piston transmission mechanism 3 is connected to the middle of the assembly platform 2, and movable positioning seats 301 are evenly installed on the piston transmission mechanism 3, and a matching positioning sensor 7 is installed between the movable positioning seat 301 and the assembly platform 2, a movable adjustment plate 302 is symmetrically and movably installed on the upper end of the movable positioning seat 301, and a lifting positioning plate 305 is also provided on the opposite side of the movable adjustment plate 302, and a mounting seat 303 is installed on the opposite side of the lifting positioning plate 305, and the mounting seat 303 is L-shaped, and the piston clamping member 306 is rotatably installed in the mounting seat 303, This structure allows the piston clamping member 306 to be rotated and clamped under the positioning of the mounting seat 303. The piston can be reliably positioned through the clamping cooperation of the piston clamping members 306 on both sides, which facilitates the quality inspection of the piston ends and sides. At the same time, the rotation angle of the piston can be adjusted as needed during the assembly of the piston to facilitate the assembly operation of the piston. A rotating shaft 304 is connected between the mounting seat 303 and the lifting and positioning plate 305. A rotating shaft limiting hole 307 is provided in the middle of the movable adjustment plate 302, and the rotating shaft limiting hole 307 is longitudinally opened, and the rotating shaft 304 is arranged in the rotating shaft limiting hole 307. This structure allows the lifting and positioning plate 305 to allow the rotating shaft 304 to be in the rotating shaft limiting hole 307 during the lifting process. The rotating shaft 304 can move in the hole 307, and the rotating shaft 304 can drive the lifting and positioning plate 305 to rotate through the stepping motor under the positioning of the mounting seat 303, so as to realize the rotation and lifting of the mounting seat 303. The movable adjusting plate 302 is symmetrically provided with lifting limit holes 308 that are movably engaged with the lifting and positioning plate 305, and the lifting limit holes 308 are arranged in parallel with the rotating shaft limit holes 307. This structure drives the lifting and positioning plate 305 to be lifted and lowered by the existing stepping motor, so as to ensure that the piston has enough rotation space and can be firmly placed on the movable positioning seat 301 when assembled. The rotating shaft limit holes 307 play a lifting and lowering limit role for the lifting and positioning plate 305, and the mounting seat 303 is respectively provided with piston clamps 306. , the two sides of the assembly platform 2 are respectively provided with a connecting rod assembly platform 4 and a connecting rod detection conveyor belt 401, a piston ring assembly platform 5 and a piston ring detection conveyor belt 501, and a piston pin assembly platform 6 and a piston pin detection conveyor belt 601, which are in corresponding positions. The positioning sensor 7 on the assembly platform 2 corresponds to the positions of the first mounting cover 201, the piston ring assembly platform 5, the piston pin assembly platform 6, the connecting rod assembly platform 4 and the third mounting cover 203, respectively. This structure adopts the existing proximity sensor as the positioning sensor 7, so that the movable positioning seat 301 can stop respectively when passing through the first mounting cover 201, the piston ring assembly platform 5, the piston pin assembly platform 6, the connecting rod assembly platform 4 and the third mounting cover 203, so as to realize quality inspection and assembly processing of various parts.A second mounting cover 202 is bolted to the side of the assembly platform 2 above the piston ring detection conveyor 501, the piston pin detection conveyor 601 and the connecting rod detection conveyor 401. This structure drives the piston ring detection conveyor 501, the piston pin detection conveyor 601 and the connecting rod detection conveyor 401 through the existing sprocket structure, so that the piston ring, the piston pin and the connecting rod can be sequentially conveyed to the detection position and the assembly position. When loading each component, the quality inspection of each component is realized, the transportation time between the inspection process and the assembly process is shortened, and the assembly efficiency is effectively improved. The length of the piston transmission mechanism 3 is greater than the length of the assembly platform 2, and the first mounting cover 201 and the third mounting cover 203 are respectively screwed and fixed at both ends of the assembly platform 2. This structure allows the piston to move on the assembly platform 2 through the piston transmission mechanism 3, so that the piston can be inspected and assembled. The mounting cover 201, the second mounting cover 202 and the third mounting cover 203 are all inverted U-shaped structures, and the first mounting cover 201, the second mounting cover 202 and the third mounting cover 203 are symmetrically installed with inclined fill lights 9 on the inner upper side. This structure provides sufficient lighting conditions for the visual inspection camera 8 through the fill lights 9 to ensure the accuracy of the quality inspection results. The visual inspection camera 8 is respectively installed in the middle of the upper end of the first mounting cover 201, the second mounting cover 202 and the third mounting cover 203. The visual inspection camera 8 of this structure uses image processing and analysis to realize automatic detection, identification and measurement of each component to ensure that each component meets the quality requirements. The piston ring assembly platform 5, the piston pin assembly platform 6 and the connecting rod assembly platform 4 are staggered. This structure allows the sides of the piston ring assembly platform 5, the piston pin assembly platform 6 and the connecting rod assembly platform 4 to have sufficient assembly space.

[0024] Working principle: When using the assembly inspection device for piston processing, first, the piston is placed on the movable positioning seat 301, and the movable adjustment plate 302 moves on the movable positioning seat 301, so that the piston clamping piece 306 clamps the piston, and then the piston transmission mechanism 3 drives the movable positioning seat 301 to move on the assembly table 2. When the piston moves to the bottom of the first mounting cover 201, the visual inspection camera 8 performs appearance inspection on the piston, and then the lifting and positioning plate 305 rises under the positioning of the movable adjustment plate 302. At the same time, the rotating shaft 304 drives the mounting seat 303 to rotate under the positioning of the lifting and positioning plate 305 through the drive of the stepper motor, and the side of the piston is inspected. After the inspection is completed, the piston is rotated to its original position and lowered and placed on the movable positioning seat 301. The rotating shaft limiting hole 307 is used to limit the rotating shaft 304 when the lifting and positioning plate 305 is lifted and lowered. The lifting and limiting hole 308 plays a role of active limiting for the lifting and positioning plate 305. The piston ring, piston pin and connecting rod are respectively on the piston The piston ring, piston pin and connecting rod are transported on the ring inspection conveyor 501, the piston pin inspection conveyor 601 and the connecting rod inspection conveyor 401. When the piston ring, piston pin and connecting rod arrive at the position below the second mounting cover 202, they are also subjected to quality inspection by the visual inspection camera 8 respectively. The side positioning sensor 7 of the movable positioning seat 301 is used in conjunction with the positioning sensor 7 on the assembly table 2, so that the movable positioning seat 301 stops in sequence below the first mounting cover 201, the side of the piston ring assembly table 5, the side of the piston pin assembly table 6, the side of the connecting rod assembly table 4 and below the third mounting cover 203, so that the piston can be assembled with the piston ring, piston pin and connecting rod in sequence, and after the assembly is completed, the quality inspection is carried out again by the visual inspection camera 8 under the third mounting cover 203 to ensure the assembly quality. The fill light 9 is used for fill light processing during the inspection by the visual inspection camera 8. During the piston assembly process, the quality inspection of each component is carried out through the detection device body 1 to ensure the piston assembly quality and efficiency, thereby completing a series of tasks.
