[0035] Working principle:

[0036] In use, the six bases 2 on the turntable 1 undergo six processes. First, an external robotic arm inverts and inserts four bolts 6 into the placement slots 24 of the four sleeves on one of the bases 2, with the threaded ends of the bolts 6 facing upwards. The turntable 1 rotates 90 degrees, and the base 2 rotates to the next position. The above steps are repeated on the next base 2 in the original position. A sprocket hub 3 is then placed on this base 2 by the external robotic arm. At this time, the four limiting blocks 31 of the sprocket hub 3 correspond to the four limiting slots 22 of the base 2, achieving coupling. Simultaneously, the central hole 32 is sleeved on the positioning post 21, and the four sleeve posts 23 are engaged. In the sleeve hole 33, four bolts 6 pass through the through-hole at the upper end of the sleeve hole 33 and extend to the upper end of the sprocket hub 3. The turntable 1 rotates 90 degrees, and the base 2 rotates to the next position. The sprocket disc 4 is placed above the sprocket hub 3 by an external robotic arm. At this time, the slot at the bottom of the sprocket disc 4 corresponds to the position of the boss at the upper end of the sprocket hub 3, achieving coupling. The positioning hole 41 of the sprocket disc 4 is sleeved with the positioning post 21 of the base 2. At the same time, the threaded part of the bolt 6 passes through the four through holes 42 and extends to the upper end of the sprocket disc 4. The turntable 1 rotates 90 degrees, and the base 2 rotates to the next position. The sprocket disc 4 is placed above the sprocket hub 3 by an external robotic arm. Washer 7 is installed on bolt 6. Turntable 1 rotates 90 degrees, and base 2 rotates to the next position. Motor 53 on pneumatic screwdriver holder 5 starts, and motor 53 drives double screw 52 to rotate, so that sliding block 54 sleeved on double screw 52 can slide in sliding groove 51, thereby adjusting the position of pneumatic screwdriver head 58 so that it is accurately aligned with the position where bolt 6 needs to be installed. Control the extension cylinder 56 to extend, so that pneumatic screwdriver head 58 is lowered to a suitable height, ensuring that nut 8 in pneumatic screwdriver head 58 can be aligned with the inverted bolt 6 in placement groove 24 and the bolts extending from sleeve hole 33 and through hole 42. With the threaded rod of bolt 6 accurately aligned, the pneumatic screwdriver bit 58 is activated, causing it to rotate and rotate the nut 8 on bolt 6. Through the cooperation of bolt 6, nut 8, and washer 7, the sprocket hub 3 and sprocket disc 4 are securely connected, completing the sprocket assembly. Motor 53 and telescopic cylinder 56 drive the pneumatic screwdriver bit 58 back to its original position. An external robotic arm inserts nut 8 into the pneumatic screwdriver bit 58, ready for the next use. Turntable 1 rotates 90 degrees, and the base 2 rotates to the next position. The external robotic arm removes the assembled sprocket. The above operation is repeated to complete the installation of multiple sprockets in sequence.
