Abstract
The invention discloses a novel hydraulic universal testing machine, which comprises an upper jaw, a lower jaw, an upper beam, columns, a connection base plate, an oil cylinder, a welding frame and an encloser. The upper beam and the upper jaw are connected integrally and are fixedly mounted on the columns arranged symmetrically; the encloser is welded around the welding frame so as to form an enclosed structure; the lower jaw is arranged on the connection base plate of the encloser through a fixing connection device; the columns are symmetrically arranged on the upper part of the encloser; the oil cylinder and a main machine are connected integrally and are arranged in the welding frame inside the encloser; and the upper jaw and the lower jaw adopt semi-enclosed jaws. The novel hydraulic universal testing machine of the invention is improved on the basis of original hydraulic universal testing machines, and employs a single space and underlaid oil cylinder structure. And the integral connection of the main machine and the oil cylinder reduces the oil circuit connection way. The testing machine provided in the invention has the advantages of compact structure, organized circuit arrangement, high positioning accuracy upper beam, precise testing, convenient testing operation, and low cost, thus being suitable for popularization and application.
Description
Technical field:
The present invention relates to a kind of testing machine, relate in particular to a kind ofly be used for that metal material stretches, compresses, the universal hydraulic testing machine of tests such as bending and shearing.
Background technology:
A complete hydraulic system is made up of five parts; Be dynamical element, executive component, control element, auxiliary element (annex) and hydraulic oil; The structure of hydraulic system is made up of signal controlling and hydraulic power two parts, and signal controlling partly is used for driving the operation valve action of hydraulic power part.
Hydraulic power partly adopts the loop diagram mode to represent, to show the mutual relationship between the difference in functionality element.Hydraulic power source contains hydraulic pump, motor and hydraulic pressure auxiliary element; Hydrostatic control partly contains various operation valves, and it is used for flow, pressure and the direction of Control work fluid; Operating part contains hydraulic cylinder or oil motor, and it can be selected by actual requirement.
When analyzing and design actual task, generally adopt actual operating state in the block scheme display device, hollow arrow expression signal stream, filled arrows is then represented energy stream.Stretching out and the opening and closing of retraction and surplus valve of the switching-over of the sequence of movement-control element in the basic liquid hydraulic circuit (two-position four way change valve) and spring reset, executive component (double acting hydraulic cylinder).For executive component and control element, PowerPoint all is based on the corresponding circuit schematic symbol, and this has also done preparation for introducing the loop diagram symbol.
According to the system works principle, can number successively all loops.If first executive component is numbered 0, then relative control element identifier then is 1.Be even number if stretch out corresponding element identifier symbol, then then be odd number with the executive component corresponding element identifier symbol that bounces back with executive component.Not only tackle hydraulic circuit and number, also tackle physical device and number, so that find the system failure.
The application of hydraulic pressure is very widely, and wherein hydraulic system applications generally has single space and two kinds of structures of double space at universal hydraulic testing machine, but no matter single space and double space structure, and its main frame and oil sources generally are separately designs.Present employed universal hydraulic testing machine stretching header portion physical construction mainly comprises: entablature, and sill, column, lead screw transmission part and stretching attach.Mainly there is following shortcoming in this mechanism: crossbeam jaw place intensity, rigidity factor of assurance are low, use jaw yielding for a long time, influence the testing machine precision, and texture ratio is heavy, and it is not very convenient using; And lead screw transmission part is linked with the gap with leading screw, influence the horizontal accuracy of crossbeam location, strengthened the error of testing.
Summary of the invention:
The objective of the invention is to be used for remedying the deficiency of prior art, and a kind of new type hydraulic universal testing machine is provided.
To achieve these goals, technical scheme of the present invention is following:
A kind of novel hydraulic universal testing machine, this testing machine comprise upper jaw, lower jaw, entablature, column, connection bedplate, oil cylinder, lead frame and case,
Said entablature is connected with the upper jaw one and is fixedly mounted on the symmetrically arranged column;
Said case forms enclosed construction around being welded in lead frame;
Said lower jaw is arranged on the connection bedplate on the case through fixed connection apparatus;
Said column is symmetricly set on case top, and it is provided with the adjusting annular groove of regulating height;
Said sensor is arranged on the lower jaw below;
Said oil cylinder and main frame one are connected in the inner lead frame of case;
Said upper jaw, lower jaw adopt semiclosed jaw.
A kind of novel hydraulic universal testing machine of the present invention improves on original universal testing machine, adopts interposed structure under single space, the oil cylinder, and main frame is connected the connected mode that has reduced oil circuit with the oil cylinder one; Test mechanism is compact, and circuit is arranged with orderliness, and upper jaw is connected with the entablature one; Connected mode is simple; Good rigidly, and the semiclosed jaw of upper jaw employing good rigidly, oil sources is installed in the framework of the welding below the testing machine; All in lead frame, it is neat and artistic that entire machine seems for the main body of oil cylinder, oil pipe, cable etc.Entablature position level precision is high, and test accurately makes things convenient for test operation, and is with low cost, suitable applying.
Description of drawings:
Further specify the present invention below in conjunction with accompanying drawing and embodiment.
Fig. 1 is a structural representation of the present invention
Embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
