The working process of this equipment is that the worker places the main body of the product chuck 3 in a row in an orderly manner in the six-station rotating silo, and the robot 7 uses a group of grabbing mechanisms to grab the chuck 3 products and put them on the servo rotating lifting platform 4 for riveting. The servo rotating lifting platform 4 starts to work and cooperates with the riveting press 6 to press the bolts and rivets on the main body of the chuck 3; during the riveting process, another chuck 3 product is grabbed and waited. After the chuck 3 product is riveted, the robot 7 uses another group of grabbing mechanisms to grab the finished product from the servo rotating lifting platform 4, and puts another chuck 3 product on the servo rotating lifting platform 4 to start riveting; during the riveting process, the robot 7 puts the finished product on the servo rotating positioning platform 5 and rotates it for a certain angle, and then grabs it to the double-row chain plate 803 conveyor belt 8 for receiving materials; the six-axis robot 7 then uses the grabbing mechanism to grab a product from the six-station rotating silo and wait. In sequence, the worker is only responsible for loading the main body of the product chuck 3 into the silo and collecting the entire row of chuck 3 products from the receiving conveyor belt 8.

[0031] After the equipment is started, the loading turntable 202 rotates to the material picking station of the robot 7 and detects the presence of products. The robot 7 receives the signal to grab the products and then places the products on the riveting rotating platform 411. After the rotating platform 411 rotates into place and the lifting cylinder descends into place, the equipment sends a downward signal to the riveting press 6 to start pressing rivets. After all rivets are pressed, the robot 7 receives the signal to grab the products and places the products on the rotating platform 2 502. After rotating a certain angle, the robot grabs the products again and places them on the double-row chain conveyor belt 8 for collecting materials.

[0032] This equipment mainly completes the process of product transportation, and the process parameters involved are mainly the riveting pressure parameters of the riveting press itself and the product quality. The process parameter group involved in this equipment is different according to the shape of the product. The rotary riveting platform needs to rotate a specific angle parameter related to the product riveting qualified rate. This equipment mainly completes the transportation of a product to the riveting platform to cooperate with the riveting press 6 to rivet rivets, and then discharges the product in a row on the receiving conveyor belt 8. The biggest advantage of the present invention is that it saves labor costs and reduces the operating skills requirements of workers. Workers only need to be responsible for loading and unloading. In addition, the equipment has a silo for loading and unloading, and a conveyor belt 8 for storage. Workers only need to load and unload materials every once in a while. The quality of the product is improved, and there will be no situation where the product is placed crooked during manual riveting, resulting in crooked rivets, and there will be no situation where rivets are missing. Improved production efficiency, more products are riveted every day than manual. The fully automatic tank chuck 3 rivet riveting equipment of the present invention is used in the production process of the tank chuck 3 for riveting rivets on the chuck 3.
