Description

Technical Field

[0001] The invention relates to the technical field of die casting detection, and in particular to an intelligent automatic visual detection device for die castings. Background Art

[0002] Die casting is a kind of pressure casting part. It is a pressure casting mechanical die casting machine equipped with a casting mold. The heated liquid copper, zinc, aluminum or aluminum alloy metal is poured into the feed port of the die casting machine. The die casting machine is die-cast to cast copper, zinc, aluminum parts or aluminum alloy parts of the shape and size limited by the mold. Such parts are usually called die castings. In the process of automobile production, the automobile engine cylinder is one of the main components of the engine. The automobile engine cylinder is mainly die-casted with aluminum alloy through a die casting machine. In order to ensure driving safety, it is necessary to perform ultrasonic flaw detection on the internal defects after the automobile engine cylinder is die-cast. Traditional flaw detection is to manually use an ultrasonic flaw detector to contact the probe with the automobile engine cylinder to detect the internal defects of the engine cylinder. After the detection is completed, if it is unqualified, it is necessary to manually use a transfer device to transfer the unqualified engine cylinder for inspection. Manual detection consumes human resources and has low production detection efficiency. During the manual transfer process, safety accidents may occur due to illegal operations, and there are hidden safety accidents. In view of the above problems, the inventor proposes an intelligent automatic visual inspection device for die castings to solve the above problems. Summary of the invention

[0050] Working principle: First, after the die-casting of the automobile engine cylinder is completed in the die-casting device, it is transported to the intermittent conveying mechanism 5 through the external conveying device, and the No. 2 driving motor 911 is controlled to be turned on. The driving end of the No. 2 driving motor 911 drives the No. 1 driving shaft 902 to rotate one circle counterclockwise through the pulley transmission group. The counterclockwise rotation of the No. 1 driving shaft 902 drives the No. 1 and a half gear 903 to rotate counterclockwise. The No. 1 and a half gear 903 rotates counterclockwise and first meshes with the No. 1 driving gear 905. The No. 1 driving gear 905 and the No. 1 and a half gear 903 have the same number of teeth. When the No. 1 and a half gear 903 meshes with the No. 1 driving gear 905, the No. 1 driving shaft 902 drives the No. 2 driving shaft 904 to rotate one circle clockwise through the No. 1 and a half gear 903 and the No. 1 driving gear 905. The driving shaft 904 rotates clockwise through the No. 2 synchronous wheel transmission group to drive the No. 1 rotating roller 501 to rotate one circle clockwise. The No. 1 rotating roller 501 drives the No. 2 rotating roller 502 to rotate one circle synchronously through the No. 3 synchronous wheel transmission group. The No. 1 rotating roller 501 and the No. 2 rotating roller 502 rotate synchronously clockwise to drive the conveyor belt to transport the automobile engine cylinder to the bottom of the ultrasonic probe 411. At this time, the No. 1 and a half gears 903 are separated from the No. 1 driving gear 905 and continue to rotate until they are meshed with the No. 2 driving gear 907. The No. 2 driving gear 907 is the same as the No. 1 driving gear 905. The No. 1 driving shaft 902 drives the No. 3 driving shaft 906 to rotate one circle clockwise through the No. 1 and a half gears 903 and the No. 2 driving gear 907. The No. 3 driving shaft 906 rotates to drive the No. 2 The number one and a half gear 908 rotates one circle clockwise, and the number two and a half gear 908 is provided with two groups of teeth symmetrically distributed. The number two and a half gear 908 rotates clockwise to drive the two groups of teeth to mesh with the number three driving gear 910 respectively. The number of teeth in each group of the number two and a half gear 908 and the number of teeth in the number three driving gear 910 are in a ratio of two to one. When the first group of teeth of the number two and a half gear 908 meshes with the number three driving gear 910, the number three driving shaft 906 drives the number four driving shaft 909 to rotate half a circle counterclockwise through the number two and a half gear 908 and the number three driving gear 910. The number four driving shaft 909 rotates half a circle and drives the number two rotating shaft 801 to rotate half a circle through the number one synchronous wheel transmission group. The number two rotating shaft 801 rotates half a circle and drives the rotating disks 802 at both ends to rotate half a circle. The two rotating disks 80 2 rotates half a circle and drives the corresponding lifting block 804 to move downward synchronously through the connecting rod 803. The two lifting blocks 804 move downward synchronously and drive the lifting frame 401 to move downward. When the lifting frame 401 moves downward, the two lifting blocks 804 drive the corresponding fixed No. 1 rack 605 to move vertically downward synchronously. The two No. 1 racks 605 move downward and drive the corresponding meshing No. 3 rotating gears 602 to rotate. The rotation of the two No. 3 rotating gears 602 drives the threaded rod 603 to rotate. The rotation of the threaded rod 603 drives the clamping rod 604 to move under the guidance of the guide column 606 and the guide frame 607. The two clamping rods 604 move toward each other synchronously and contact the cylinder of the automobile engine to clamp and fix the engine cylinder.The clamping rod 604 clamps the cylinder of the automobile engine. At this time, the lifting frame 401 moves downward to drive the ultrasonic probe 411 to contact the top of the cylinder of the automobile engine;

[0051] At this time, the first set of teeth of the second half gear 908 is separated from the third driving gear 910, and the third driving shaft 906 continues to rotate to drive the second set of teeth of the second half gear 908 to mesh with the third driving gear 910. After the first set of teeth are separated from the third driving gear 910 and before the second set of teeth are meshed with the third driving gear 910, the first set of teeth is separated from the third driving gear 910 and at the same time, the first driving motor 412 is controlled to be turned on. The driving end of the first driving motor 412 rotates through the second rotating gear 413 and the first rotating gear 403 to drive the first rotating shaft 402 to rotate one circle. The moving shaft 402 rotates one circle to drive the rotating rod 404 to rotate one circle. The rotating rod 404 rotates and slides in the No. 1 sliding frame 405 through the end fixed column, thereby driving the No. 1 sliding frame 405 to move back and forth once. The reciprocating movement of the No. 1 sliding frame 405 drives the ultrasonic probe 411 to slide back and forth once on the top of the automobile engine cylinder. The ultrasonic probe 411 transmits the ultrasonic detection data of the automobile engine cylinder to the ultrasonic flaw detection device 10 through the data line. After the data analysis of the ultrasonic flaw detection device 10, it is determined whether the detected automobile engine cylinder is qualified and the data is transmitted to the driving electric cylinder 711.

[0052] After the ultrasonic probe 411 has finished testing, the second set of teeth of the second half gear 908 meshes with the third drive gear 910, and the third drive shaft 906 continues to drive the fourth drive shaft 909 to rotate half a circle through the second half gear 908 and the third drive gear 910, and the fourth drive shaft 909 drives the second rotating shaft 801 to continue to rotate half a circle, and the second rotating shaft 801 continues to rotate half a circle to drive the lifting frame 401 to reset, and the lifting frame 401 rises and drives the clamping rod 604 to reset through the above reverse steps;

[0053] After the tested automobile engine cylinder moves to the transfer conveyor belt on the sorting and conveying mechanism 7, the driving electric cylinder 711 is sorted according to the data. When the automobile engine cylinder is qualified, the driving electric cylinder 711 is kept stationary, and the qualified engine cylinder is conveyed to the external transfer conveyor belt through the transfer conveyor belt for subsequent inspection. When the engine cylinder is unqualified, the driving electric cylinder 711 is operated. At this time, the driving end of the driving electric cylinder 711 extends and pushes the moving frame 704 to move. The moving frame 704 moves through the No. 2 rack 703 to drive the No. 4 rotating gear 705 to rotate. While the No. 4 rotating gear 705 rotates, it drives the No. 2 sliding frame 702 to move through the No. 3 rack 707. The No. 2 sliding frame 702 slides to move the transfer conveyor belt to dock with the unqualified special transfer conveyor belt, and the unqualified automobile engine cylinder is transferred through the unqualified special transfer conveyor belt.
