The compression spring being enclosed within guide pillar is additionally provided between substrate, the briquetting is located between microcephaly's grip block and major part support block,
And the movable connection in lever one end away from substrate side and leverage of the briquetting；The expansion link and lever of the cylinder
The movable connection of the other end.
Further, the two ends of the lever be respectively provided with opening towards substrate spherical groove, the briquetting away from
Substrate side is provided with the horizontal cross bar matched with spherical groove, and the Telescopic-cylinder bar is provided with the end of horizontal cross bar
Size less than spherical groove ball coronal structure and respectively with stretch into two spherical grooves.
Compared to prior art, the utility model has the advantages that：During utility model works, connecting rod is positioned over
On spacing bearing and positioned between briquetting and substrate, the stub end of connecting rod and small head end are respectively at two boring cutter through holes, so
Start Telescopic-cylinder bar afterwards to protract and move briquetting towards substrate by lever construction, and then realization compresses connecting rod, while pressure
Contracting spring puts aside elastic potential energy, you can start bore hole treatment；Retracted when control Telescopic-cylinder bar after bore hole is processed is completed, then briquetting
Resetted in the presence of compression spring, you can take out the connecting rod that bore hole is finished；Therefore the clamping of connecting rod is enhanced with pickup just
Victory, improves processing efficiency.
Brief description of the drawings
Fig. 1 is structural front view of the present utility model.
Fig. 2 is structure right view of the present utility model.
Fig. 3 is working condition front view of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further illustrated to the technical scheme in the utility model.
As shown in figure 1, the utility model proposes a kind of fixture for boring machine for crankshaft-link rod production, including be vertically arranged
Substrate 11, the spacing bearing for being fixed on the side wall of substrate 11, the cylinder 12 that is horizontally fixed on substrate 11 and by Lever machine
The briquetting 14 that structure 13 is connected with the expansion link 121 of cylinder 12, wherein：
Be provided with the substrate 11 for by substrate 11 be arranged on boring machine on slotted hole 111 and respectively with connecting rod 10
Two boring cutter through holes 112 that stub end and small head end match；
The spacing bearing includes substantially being distributed in microcephaly's grip block 15 and major part support block 16 in same level direction, institute
The side towards major part support block 16 for stating microcephaly's grip block 15 is provided with breach 151 of the opening towards major part support block 16,
It is trapezoidal that what the perpendicular that the breach 151 is parallel to the surface of substrate 11 was intercepted be shaped as, and the breach also may be designed as
Triangle；As shown in figure 3, when connecting rod is placed, the small head end of connecting rod is snapped in the breach, due to indentations section for trapezoidal or
Triangle, is applicable to the connecting rod of various sizes；The major part support block 16 has a bearing diagonal towards microcephaly's grip block 15
