Described actuating unit comprises the pull bar that is located in the chuck body axial passage, the pull bar front end is fixedlyed connected by branch sleeve with piston rod, the pull bar rear end silk braid tube that is spirally connected, silk braid tube front end is provided with ring baffle, the silk braid tube hold-down nut that is spirally connected outward, silk braid tube between hold-down nut and the ring baffle is fixed with circular end cap outward, and the anterior circumference of end cap outer end is provided with the annular jacking block that is connected with the pushing of tapered sleeve tube rear end.
Described tapered sleeve tube and elasticity support set all are provided with two, are provided with annular spacer between two tapered sleeve tubes, and annular spacer and chuck body are slidingly connected, and annular spacer bottom front end is provided with toroidal cavity.
Be equipped with stop screw on described two elasticity support sets, two tapered sleeve tube outer surfaces are provided with the spacing hole that cooperatively interacts with stop screw.
Adopt said structure, the workpiece cover is installed on the elasticity support set, after the hydraulic jack work, the piston rod post-tensioning also moves to left by pull bar pulling end cap, cause the elasticity support set on the ladder conical surface of tapered sleeve tube, moved by end cap extruding back, the elasticity support set makes workpiece self-centering and clamped owing to be subjected to the effect of tapered sleeve tube and expansion radially outward equably at inwall simultaneously.The utility model centering precision height, workpiece loading and unloading are quick and convenient, and only need change tapered sleeve tube and elasticity support set when changing the line of production, and can realize changing fast frock, shorten and produce non-cutting time, enhance productivity, thereby reduce production costs.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, two inner support cylindrical centralizers that push away of the present utility model, it comprises that hydraulic power unit, actuating unit, center have the chuck body 4 of axial passage and be set in chuck body 4 elasticity support set 6 and elasticity support set 9 outward.Actuating unit comprises the pull bar 13 that is located in chuck body 4 axial passages, and hydraulic power unit comprises hydraulic jack 1, piston 2 and piston rod 20, and piston rod 20 is fixedlyed connected with pull bar 13 front ends by branch sleeve 3.Be arranged with tapered sleeve tube 5 and tapered sleeve tube 8 between chuck body 4 and elasticity support set 6 and the elasticity support set 9 respectively, tapered sleeve tube 5 is all fixedlyed connected by screw 21 with chuck body 4 with tapered sleeve tube 8, elasticity support set 6 is slidingly connected with tapered sleeve tube 5, elasticity support set 9 is slidingly connected with tapered sleeve tube 8, elasticity support set 6 and tapered sleeve tube 5, elasticity support set 9 is the ladder taper with tapered sleeve tube 8 mating surfaces, elasticity support set 6 is all parallel with the center line of chuck body 4 with elasticity support set 9 outside cylinder buses, be provided with annular spacer 7 between elasticity support set 6 and the elasticity support set 9, annular spacer 7 is slidingly connected with chuck body 4, annular spacer 7 bottom front ends are provided with toroidal cavity 30, in order to avoid tapered sleeve tube 5 stops spacer 7 move left and right.The pull bar 13 rear ends silk braid tube 12 that is spirally connected, silk braid tube 12 front ends are provided with ring baffle 19, the silk braid tube 12 outer hold-down nuts 11 that are spirally connected, be fixed with circular end cap 10 outside the silk braid tube 12 between hold-down nut 11 and the ring baffle 19, end cap 10 anterior circumference outer ends are provided with the annular jacking block 31 that is connected with the pushing of tapered sleeve tube 9 rear ends.Be equipped with stop screw 50 on elasticity support set 6 and the elasticity support set 9, tapered sleeve tube 5 and tapered sleeve tube 8 are provided with the spacing hole 51 that cooperatively interacts with stop screw 50, and stop screw 50 and spacing hole 51 can prevent elasticity support set 6 and 9 slippages of elasticity support set.
