the back shelves stand with lean on shelves locating component one-to-one behind the first, back shelves stand is located each and moves the correction space between correction piece and the fixed correction piece that corresponds, and back shelves stand supports on the face of vertical fixed backup plate.
Third, two first back lean on shelves locating component's pass actuating mechanism simultaneous movement, drive the vertical connecting rod of second and remove toward first vertical connecting rod direction, at this in-process:
the second vertical connecting rod drives the vertical movable limiting plate to move towards the rear gear upright post, the rear gear upright post is positioned between the corresponding vertical fixed backup plate and the vertical movable limiting plate, and the rear gear upright post is limited through the vertical fixed backup plate and the vertical movable limiting plate;
then, the second vertical connecting rod continues to move towards the first vertical connecting rod, and after the vertical linkage push plate abuts against the first vertical connecting rod, the second vertical connecting rod drives the first vertical connecting rod and the movable correcting block on the first vertical connecting rod to be close to the corresponding fixed correcting block, so that the movable correcting block and the fixed correcting block of the first rear-rest positioning assembly are matched to correct and position the rear-rest upright post of the rear-rest;
meanwhile, the first vertical connecting rod and the movable correcting block on the first vertical connecting rod are close to the corresponding fixed correcting block, and in the process of correcting and positioning the rear gear stand column, the rear gear stand column is always positioned between the corresponding vertical fixed backup plate and the vertical movable limiting plate, and the rear gear stand column is limited by the vertical fixed backup plate and the vertical movable limiting plate, so that the rear gear stand column is prevented from moving in the direction perpendicular to the vertical fixed backup plate in the process of correcting and positioning the rear gear stand column of the rear gear by matching the movable correcting block and the fixed correcting block, and the correction and positioning accuracy of the rear gear stand column is ensured;
therefore, the installation and the positioning of the rear leaning gear can be facilitated, the rear leaning gear does not need to be installed in an auxiliary mode such as hammer beating, the installation efficiency is improved, the working strength of workers is reduced, the rear leaning gear can be corrected, the size precision of the rear leaning gear is improved, and the overall size precision of the headstock is further improved.
Fourthly, after the pedal upright post is connected with the rear leaning block in a welding mode, the pushing executing mechanism drives the second vertical connecting rod to move until the second guide rod limiting block abuts against the end face of the second horizontal guide sleeve; when the second guide rod limiting block abuts against the end face of the second horizontal guide sleeve, the first vertical connecting rod abuts against the end face of the first horizontal guide sleeve under the action of the first reset spring, and at the moment, the distance between the movable correcting block and the corresponding fixed correcting block is the largest, so that the rear leaning block is removed from being fixed, and the rear leaning block can be taken down conveniently.
