Description
Technical field
The present invention relates to measurement mechanism field, at length say it is a kind of Mechanics Performance Testing loading system.
Background technology
Well-known: in Mechanics Performance Testing field, what loading system extensively adopted is on single oil cylinder underlying and single oil cylinder, to put two kinds of loading structures.
Single oil cylinder underneath type structure be hydraulic jack below worktable, more than worktable by column and moving beam and entablature formation compression stroke and stretching space.This type of main frame reduces than height with the main frame of type the earliest, is beneficial to testing laboratory and puts.Just because of oil cylinder underlying, in the time of the height of compression complete machine, also brought fatal problem, because all load is all positioned on the load sensor that oil cylinder piston installs.In loading process, very easily cause various non axial perturbed forces to be added on sample, cause the stressed complexity of sample, affect experimental accuracy.The load accuracy of this type of loading system is difficult to reach 0.5 grade.
Single oil cylinder overhead loading design feature has been avoided some fatal shortcomings of single oil cylinder underneath type loading structure, accuracy has improved much, reaching 0.5 grade of accuracy is still relatively easy to, but because structural condition limits, load sensor is generally mounted in below lower chuck, make load sensor more or less can be subject to non-axial force and disturb, can not well react the stressing conditions of sample.
Because single oil cylinder overhead loading structure should be considered sample loading, consider that again the large stroke of fixture 600mm-700mm moves, so the oil cylinder of this type of main frame is very long, and oil cylinder is installed on the entablature of main frame in addition.Therefore cause measurement main frame to have very high height, the measurement height of main frame of general 60T is more than 3 meters, adds hoisting height, and ordinary test chamber is to meet this height.
Owing to being single oil cylinder loading, so oil cylinder volume is larger, unloads oil mass very large, and due to spool flow restriction, piston return speed is slow.Test for scientific research institutions can meet the demands, but for quality testing mechanism, just shows the problem that efficiency is not high.
Summary of the invention
Object of the present invention is just to overcome the deficiencies in the prior art, and a kind of Mechanics Performance Testing loading system is provided, and can guarantee that sensor is subject to direct axial force, there is no the interference of other non-axial force, can show accurately the stressing conditions of sample; After loading completes, oil cylinder return speed is very fast, has improved greatly the efficiency of test; Oil cylinder and test space can be arranged in parallel, greatly reduce device height, make common laboratory can both meet this height.
The present invention adopts following technical solution: a kind of Mechanics Performance Testing loading system, be provided with worktable, it is characterized in that, both sides, worktable top are vertically installed with respectively a guiding thick stick, two guiding thick stick upper ends are fixed with entablature, on two guiding thick sticks, be set with moving beam, worktable middle part is fixed with lower clamp coupling arrangement, moving beam middle part is provided with fixture coupling arrangement, the guide pole of upper fixture coupling arrangement is through moving beam, guide pole upper end is provided with platen, on the moving beam of platen below, pressure transducer is installed, lower clamp coupling arrangement is positioned under fixture coupling arrangement, equidistantly on the worktable of lower clamp coupling arrangement both sides be vertically installed with respectively an oil cylinder, the expansion link upper end of oil cylinder is fixed on moving beam below.
The invention has the beneficial effects as follows, simple in structure, adopt the loading of two oil cylinder feed rod guiding, can guarantee that sensor is subject to direct axial force, there is no the interference of other non-axial force, can show accurately the stressing conditions of sample.Adopt two oil cylinder loading modes, the small volume of oil cylinder, after loading completes, oil cylinder return speed is very fast, has improved greatly the efficiency of test.Owing to adopting two oil cylinder loading modes, oil cylinder and test space can be arranged in parallel, greatly reduce device height, make common laboratory can both meet this height.
