(3) utility model content:

The purpose of this utility model is to design a kind of alignment hydraulic press, and it can solve the deficiencies in the prior art, is a kind of automaticity and production efficiency height, economical with materials and occupation of land space, alignment hydraulic press that the alignment precision is high.

The technical solution of the utility model: a kind of alignment hydraulic press, comprise the twin columns hydraulic press, it is characterized in that it comprises that also workbench, adjustable seats, operation wheels, walking wheels, v block, tumbler, pipe connecting device, dial gauge test tool and Hydraulic Station; Wherein, workbench is connected according to bolt with adjustable seats; Said twin columns hydraulic press places on the walking wheels; Said walking wheels are sliding connection according to roller and workbench; Said operation wheels are connected with the twin columns hydraulic press, and are moved by the hydraulic system driving twin columns hydraulic press that is fixed in the twin columns hydraulic press; Said tumbler comprises the main tube device that is installed on the workbench two ends respectively and from the tube device, main tube device is connected with Hydraulic Station; Said pipe connecting device places to be on the workbench as the strong point that floats can regulate installation, and is driven by pneumatic system; Said v block places to be on the workbench as the fixing centering strong point can regulate installation; Said dial gauge is tested tool and is fixed on the workbench, and is fixed on the alignment point by its magnetic force.

Above-mentioned said twin columns hydraulic press comprises fuel tank, single-piston rod oil cylinder, locknut, crossbeam, slide block, column and bottom girder; Wherein fuel tank is according to sealing ring be bolted to single-piston rod oil cylinder bottom, and by prefill valve the single-piston rod oil cylinder carried out oil-filled and oil extraction; Said single-piston rod oil cylinder is fastened on the crossbeam middle part according to end seam and locknut, and its piston rod head is blue in accordance with the law to be connected with slide block with bolt; Said column lower end is fastened on both sides, bottom girder front and back according to its seam and locknut, passes slide block on it and fixedlys connected with crossbeam according to adjusting nut and locking nut.

This equipment hydraulic system, pneumatic system are controlled by electrical system.

The course of work of the present utility model: 1. workpiece is placed on the v block, by main tube device with from tube device rotational workpieces, tests tool by dial gauge and finds out workpiece maximum deflection point; 2. slide block is moved to by operating component and walking wheels and desire the alignment point, workpiece is exceeded the proper limits in righting a wrong, this moment, pipe connecting device held up workpiece, and to bear pressure, v block does not stress, and it has higher accuracy of alignment; 3. using dial gauge to test tool finds out the maximum deflection point once more and carries out alignment; 4. meet technological requirement up to the workpiece linearity.

Superiority of the present utility model: 1. static by the alignment part, main frame moves, and than the workbench contraction in length 2/3 of alignment same axis farm labourer part, saves 15% steel; Manual compacting constitutes detection feedback system with the supporting test point, and the alignment precision is less than 0.3mm; By the alignment part rotatablely move, distance is all finished by the hand push button crawl between the supporting-point; 3. drag the main frame move left and right by the walking wheels, selecting gear, chi bar for use is transmission mechanism, makes the main frame mobile accuracy within 0.2mm; 4. automaticity and production efficiency height, economical with materials and occupation of land space, alignment precision height are especially to alignment large-scale long shaft class, more outstanding its advance of section bar.
