seventhly, in a lead screw greasing station (12), a lead screw grease applying device (21) is used; firstly, clamping the bottom of a screw piece (1) and driving the screw piece (1) to rotate through a screw auxiliary pair wheel (70) of a screw upper clamping hand (71) and a screw auxiliary pair wheel (70) of a screw lower clamping hand (72); secondly, the screw rod greasing nozzle (73) is lifted on the frame assembly and is meshed with the external thread of the screw rod piece (1) and greased;
eighthly, at the slide block screwing-in station (13), by means of a slide block feeding structure (22), a slide block material staggering structure (23), a slide block conveying mechanism (24) and a slide block screwing-in mechanism (25); firstly, pre-storing a sliding block piece (5) in a vertical channel of the sliding block piece (5); then, the sliding block pieces (5) are output one by one from the bottom of the vertical channel by a sliding block bottom tray (75); secondly, the sliding block dislocation pushing hand (76) horizontally pushes the sliding block piece (5) exposed out of the bottom tray (75) of the sliding block from the lower end of the falling channel (74) to the sliding block horizontal conveying holding hand (77) and clamps the sliding block piece; thirdly, the linear reciprocating driver pushes the sliding block horizontal delivery supporting hand (77) to horizontally deliver the sliding block piece (5) to the sliding block screwing-in station (13), and the sliding block horizontal delivery supporting hand (77) places the sliding block piece (5) on the sliding block assembling rotating sleeve (79); subsequently, the slide assembly shoe (78) is raised and the slide rotation head (80) is rotated, so that the slide part (5) is screwed in on the spindle part (1);
and step nine, outputting the assembled screw rod piece (1) through a manipulator at an output station (14).
