Fixing riveting post, retainer plate is provided with fixture, and fixture is used for for workpiece to be processed being fixed on retainer plate, and the both sides of retainer plate are provided with
The through hole of symmetrical more than four, guide pillar is fixed on base plate, and guide pillar is passed through corresponding through hole and coordinated with through hole, and guide pillar covers
Have spring, both ends of the spring is fixed with plate top surface and retainer plate bottom surface respectively, the both sides of retainer plate be provided with more than four symmetrical
Projecting block, the exterior contour of projecting block and the groove of line slideway be adapted, and what line slideway was symmetrical is fixed on base plate, support
On flitch, each projecting block is all disposed within the groove of corresponding line slideway and is coordinated with line slideway.
Linear bearing is cased with described guide pillar, linear bearing is coordinated with guide pillar, linear bearing is fixed on the logical of retainer plate
Kong Zhong.
Described riveting post clamping device includes one group of symmetrical cylinder, and the front end of two cylinder push-rods is respectively fixed with a pressure
Block, two briquettings are equipped with the groove being adapted with riveting post profile, and when two briquetting contacts, the groove in two briquettings can
To form the identical profile of clamping part with riveting post.
The invention has the beneficial effects as follows:
Contribute to reducing the relative sliding of riveting post and workpiece to be processed by retainer plate, guide pillar and the cooperation of spring floating formula
Move, retainer plate is passed through projecting block and coordinated so that riveting post is higher with the positional precision of workpiece to be processed with line slideway, and be aligned is more accurate
Really.
