Cubic hinge press hinge beam
Technical field
The utility model belongs to diamond synthesis device technical field, relates in particular to the synthetic cubic hinge press hinge beam of a kind of diamond.
Background technology
The cubic hinge press synthesis device is that diamond is produced special equipment, as shown in Figure 1, in order to guarantee the precision of press, adopts identical six hinge beam assemblies to be formed by connecting by pin hinge in the design usually, makes simple, easy for installation.But traditional press is three ears and the two ear cross-join that adopt the hinge beam, and assembling and maintenance are inconvenient.
The utility model content
The purpose of this utility model provides the simple cubic hinge press hinge of a kind of assembling beam.
The utility model is realized above-mentioned purpose by the following technical solutions: cubic hinge press hinge beam, comprise hinge beam and chain ear, and the chain ear departs from hinge beam section center line and is arranged on the hinge beam, and a side is one in the same way.
The chain ear is provided with near the center line homonymy in the same way, and the chain ear is not positioned at center line homonymy in the counterclockwise direction in the same way.
The hinge beam is a core structure, and a tube end central authorities have through hole, and piston is positioned at the hinge beam, passes the plug of opposite end mounting strap oilhole at the bottom of the hinge beam tube the through hole of piston rod at the bottom of the tube.
The chain ear of the utility model hinge beam adopts monaural, and depart from hinge beam section center line and be arranged on the hinge beam, a side is one in the same way, the chain ear is provided with near the center line homonymy in the same way, the chain ear is not positioned at center line homonymy in the counterclockwise direction in the same way, the chain ear of six hinge beam assemblies intersects mutually during assembling, is linked together easy accessibility by bearing pin, in addition, the hinge beam adopts back dress piston type, and with the stifled split design of hinge beam and back, the hinge beam is not subjected to axial force in the course of work, requirement of strength to the hinge beam significantly reduces, the beam body shortens, and wall thickness reduces, and the device fabrication cost is also low.

The specific embodiment
Shown in Fig. 2,3, cubic hinge press hinge beam, comprise hinge beam 8, chain ear 4,5,6,7 departs from hinge beam 8 kernel of section lines and is arranged on the hinge beam 8, a side is one in the same way, chain ear 4,6 is positioned at the left side of the vertical center line of hinge beam section, and chain ear 5,7 is positioned at the bottom of hinge beam 8 cross section horizontal center lines.Hinge beam 8 is a core structure, tube end center drilling, and piston 9 is positioned at hinge beam 8, and piston rod tapping at the bottom of the tube passes, the plug 10 of opposite end fixed installation band oilhole 11 at the bottom of 8 on the hinge beam.
