Abstract
The utility model relates to a loading device for an electric hydraulic pressure tester. Flexible diaphragm is clamped by the base of an oil cylinder and the upper cover of the oil cylinder. A pre-pressing oil cavity is arranged below the inner flexible diaphragm and is communicated with an oil nozzle; a support plate which can move up and down in the hollow cavity is arranged above the flexible diaphragm, and a support post which is connected with the support plate extends outside through the guide hole of the upper cover of the oil cylinder to be connected with a lower bearing plate which can be placed with test pieces. Pressure oil enters the pre-pressing oil cavity to lead the flexible diaphragm to bulge upward and deform, and the support plate and the support post are pushed to move upward to load the test pieces. The utility model has the advantages of novel design, simple structure, convenient processing and assembly, light weight, low cost, no oil leakage, high stability and small measuring error.
Description
The utility model relates to a kind of part of appliance of building materials strength test, particularly a kind of device that the electric hydraulic pressure testing machine of Non-metallic Building Materials strength test is used for loading.
In the existing specialized building materials test macro, be used for the building materials strength test of quality control, in particular for the strength test of brittle non-metallic material test specimen,, mostly use the electric hydraulic pressure testing machine as strength test to building materials test specimens such as cement, concrete, brick, stones; And this class testing machine generally adopts is the piston oil-cylinder structure of clearance seal or compound seal, realizes loading to test specimen according to this structure.The shortcoming of this piston oil-cylinder structure is that processing technology is strict, cost is high, heavy, and easily produce oil seepage, can increase test error.
The purpose of this utility model just provides a kind of new electric hydraulic pressure testing machine loading system, i.e. flexible partition oil cylinder, or be called dish film oil cylinder.To substitute the piston oil-cylinder structure of existing electric hydraulic pressure testing machine.
The utility model purpose is to adopt following technical proposals to realize.
This testing machine loading system is different from the piston oil-cylinder structure of existing testing machine fully, is a kind of design of novelty of instead of piston cylinder structure.By oil cylinder chassis, flexible partition, take over a business, fore-set, oil cylinder loam cake and oil nozzle and screw assemble.Oil cylinder chassis, flexible partition and oil cylinder loam cake are linked into an integrated entity by screw, and pre-pumping cavity below the inner formation of oil cylinder flexible partition and the cavity above the flexible partition.On the oil cylinder chassis, there is through hole to be connected in the middle of the pre-pumping cavity below the flexible partition with oil nozzle; Taking over a business of being connected with fore-set arranged in cavity above the flexible partition, and the following bearing plate that the pilot hole that fore-set covers on oil cylinder is put test specimen connects.
Flexible partition is made the disc shape by the oil resistant resilient material.
The surface of contact of oil cylinder chassis and flexible partition is step.
Pre-pumping cavity below the flexible partition is little, and top cavity is big.
Advantage of the present utility model is that the ram cylinder of the existing relatively electric hydraulic pressure testing machine of the design of this flexible partition oil cylinder is a kind of completely new concept, is a kind of substitute products that the internal difference is arranged.It simple and compact for structure, be easy to process and assemble, in light weight, cost is low, and do not have leakage of oil, stability is high, measuring error is little.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is an assembling synoptic diagram of the present utility model.
Among the figure, the 1st, oil nozzle, the 2nd, oil cylinder chassis oil through, the 3rd, pre-pumping cavity, the 4th, take over a business, the 5th, the pressure-bearing sill of testing machine, the 6th, oil cylinder chassis, the 7th, flexible partition, the 8th, screw, the 9th, oil cylinder cavity, the 10th, oil cylinder loam cake, the 11st, fore-set pilot hole, the 12nd, fore-set, the 13rd, the following bearing plate of storing test specimen, the 14th, test specimen, the 15th, the last bearing plate of test specimen, the 16th, the pressure-bearing entablature of testing machine.
The utility model is by oil nozzle (1), oil cylinder chassis (6), flexible partition (7), takes over a business (4), fore-set (12), oil cylinder loam cake (10) and screw (8) and assemble, and be installed on the pressure-bearing sill (5) of pressure test machine worktable as shown in Figure 1.Oil through (2) in the middle of oil nozzle (1) and oil cylinder chassis (6) is connected, by the screw (8) of periphery with oil cylinder chassis (6), flexible partition (7), take over a business (4), fore-set (12) and oil cylinder loam cake (10) and assemble into an integral body.Between the flexible partition of oil cylinder inside (7) and oil cylinder chassis (6) pre-pumping cavity (3) is arranged, the cavity (9) that makes (4) up and down is arranged between flexible partition (7) and the oil cylinder loam cake (10).Pre-pumping cavity (3) is little, and cavity (9) is big.Flexible partition (7) adopts the oil resistant resilient material, and disc shape preferably, with following step oil cylinder chassis (6) plane contact.Above the flexible partition (7) with take over a business the pilot hole (11) of fore-set (12) on oil cylinder loam cake (10) that (4) be connected and stretch the outside and be connected with the following bearing plate (13) of top placement test specimen (14).
When anti-folding that carries out building materials or compressive strength test, test specimen (14) is placed down between the last bearing plate (15) of pressure-bearing entablature (16) of bearing plate (13) and testing machine machine, start-up system, pressure oil enters pre-pumping cavity (3) by oil nozzle (1), because flexible partition (7) is clamped sealing by oil cylinder chassis (6) and oil cylinder loam cake (10), the oil that enters pre-pumping cavity (3) strengthens with pressure and makes the distortion of flexible partition (7) epirelief, above have a guiding take over a business (4) and fore-set (12), upwards promoted test specimen (14) loading is fractureed or fragmentation until test specimen (14) by flexible partition (7).
The utility model loading has at present reached 5KN to 2000KN, and working condition is very good.
