Description
Technical Field

Background
It is known that in the manufacture of rear seats of automobiles, the guide rail workpieces forming the seat frame need to be assembled with screws at specified positions before being welded into finished products so as to increase the overall strength of the seat frame. Therefore, the screw and nut assembling torque at the position is very critical.
The traditional assembly method is manual operation, and screws, bolts and workpieces are respectively placed in place in sequence and then assembled and screwed down. This operation has the following disadvantages:
the nuts need to be manually fed into the assembly position, and the operation efficiency is low. The guide rail rectangular tube has a narrow inner cavity and a deep position, and it is difficult to clamp the nut workpiece by fingers to reach the correct position. The productivity is seriously affected.
The staffing increases. Even if the auxiliary tool is held to send the nut to a designated position, the posture of the nut still needs to be kept until the tightening is finished, and at the moment, both the screw and the tightening tool still need to be held by hands, and both hands cannot work.
The assembly torque is wrong, and the position angle is leaped after the nut is assembled. After the nut is manually conveyed in place, if the anti-rotation limit is not available, the nut rotates along with the screw in the tightening process, the torque cannot reach the nut, or after the torque is barely reached and the nut stops, the four sides of the square nut and the direction of the guide rail generate large-amplitude angle deviation.
The rejection rate of the screws and the nuts is too high, corresponding screw and nut workpieces must be scrapped after the torque value is wrong, the cost is increased, and the working hours are wasted in disassembly.
