Fig. 1 is the utility model structural representation.
Description of reference numerals: 1, hydraulic shear cutting frame; 2, fixing tapered wedges; 3, mobile tapered wedges; 4, drive unit; 6, shear cutting edge; 7, shear knife rest; 8, fixed block; 9, guide finger; 10, holddown spring; 11, housing pin; 12, compact heap.
The specific embodiment
A kind of hydraulic tool containing blade clearance adjusting device, as shown in Figure 1, comprise hydraulic shear cutting frame 1, by twice parallel transverse slide rail, be fixed on the shearing knife rest 7 on hydraulic shear cutting frame 1 and be arranged on the shearing cutting edge 6 of shearing on knife rest 7, on hydraulic shear cutting frame 1, be also provided with fixedly tapered wedges 2, mobile tapered wedges 3, drive unit 4 and shearing knife rest lateral thruster;
Drive unit 4 connects to drive this to move tapered wedges 3 knee-actions with mobile tapered wedges 3; Described mobile tapered wedges 3 and shear knife rest 7 and be placed in fixedly tapered wedges 2 and shear between knife rest lateral thruster, makes fixedly that tapered wedges 2, mobile tapered wedges 3, shearing knife rest 7 and shearing knife rest lateral thruster are parallel is successively close to arrangement; The inclined-plane of the inclined-plane of mobile tapered wedges 3 and fixing tapered wedges 2 is relative and be set parallel to each other.
Described shearing knife rest lateral thruster is by fixed block 8, guide finger 9, and holddown spring 10, housing pin 11 and compact heap 12 form;
Described compact heap 12 is placed in described fixed block 8 and shears between knife rest 7;
On described fixed block 8, offer the tapped through hole perpendicular to described compact heap 12, holddown spring 10 is placed in this tapped through hole, the outer end thread connection of described housing pin 11 and this tapped through hole; Conflict in the inner of described housing pin 11 in the outer end of holddown spring 10, the inner of this holddown spring 10 presses on described compact heap 12;
