step five: the cover plate feeding method comprises the steps that a cover plate is fed from a conveying mechanism (2) to a transfer seat (604) through a third moving mechanism (601) and a first translation clamping cylinder (602), the cover plate is conveyed from the transfer seat (604) to a bracket at a cover plate feeding station through a fourth moving mechanism (605) and a second translation clamping cylinder (606), after the second translation clamping cylinder (606) is loosened, a cover plate pressing-in mechanism (7) is started, a first oil cylinder (7011) drives a second pressing rod (7013) to press down to abut against an upper pressing block (7022), a lower pressing block (7023) connected with the upper pressing block (7022) presses the cover plate into the bracket, and the cover plate pressing-in depth is detected through a fifth displacement sensor (7014);
step six: riveting, a rotary driving motor (802) drives a riveting shaft (804) to rotate, a second servo electric cylinder (801) drives a vertical sliding table (803) to descend, three riveting rollers (805) below the riveting shaft (804) are in contact with the upper edge of an opening of a bracket, a suspended bracket seat (101) sinks, the bottom of the bracket seat (101) is in contact with a supporting seat (16) to form a support, the riveting shaft (804) continues to press and rivet downwards, the upper opening of the bracket is turned over to press a cover plate tightly, and the second servo electric cylinder (801) stops after the riveting shaft (804) descends to a set height and then resets;
step seven: the height detection is carried out, the first detection pressure head (9022) is pressed at the spin-riveting flanging, the first displacement sensor (9024) is used for detecting the height of the spin-riveting flanging, the detection pressure head is switched through the sliding table assembly (9021), the second detection pressure head (9023) is pressed on the telescopic pin to press down and retract the telescopic pin, the second detection pressure head (9023) abuts against a steel plate in the middle of the rubber pad, and the second displacement sensor (9025) is used for detecting the height of the rubber pad;
step eight: blanking, namely taking the product off the bracket seat (101) through a blanking mechanism (10);
step nine: and resetting, namely, the reset push rod is driven to ascend through resetting, and the lifting pin (1015) is jacked up to reset.
