The invention relates to an automatic assembling
machine of expansion screw bolts and belongs to the field of hardware machinery. The assembling
machine consists of a chain plate type conveying device, a part feeding device, a part
escapement device, a screw nut screwing device, a screw rod
small head lateral positioning device, a
machine frame and a
control system, wherein the part feeding device and the part
escapement device are used for the
ranging, the storage for
package and the one-by-one release of parts, the chain plate type conveying device is arranged on the machine frame, semi-finished products and finished products with different stations are transferred through expansion screw bolt seat combination elements arranged on a chain plate, the screw rod
small head lateral positioning device is arranged at the front end of the part
escapement device for realizing the
lateral positioning of each
station screw rod, the screw nut screwing device comprises a screw nut pre-screwing friction plate, a first screw nut screwing wheel, a clamping stagnation release friction plate, a second screw nut screwing wheel, a small motor and the like. The assembling machine can realize the automatic
assembly of each part of the expansion screw bolts and has the characteristics that the
assembly efficiency is high, and the cost is low; and screw nuts are subjected to two links of pre-screwing and screwing, and the
assembly quality is ensured.
