Under a condition of guaranteeing the impact mechanism to be integrated, the testing system provided by the invention carries out on-line accurate tests to impact performance parameters of the impact mechanism.
Description
Technical field
The present invention relates to a kind of beater mechanism impact property test macro.
Background technology
Hydraulic impact mechanism is widely used in the every field such as mining, metallurgy, building, machining, carries out Drilling or the various broken work of foundation construction, tunnel excavation, exploration, quarrying, mining blast hole.Ballistic work and frequency of impact are the important performance characteristic of beater mechanism.The method of test impact property mainly is stress wave and air pressure indirectly testing method at present.Stress wave exists test value less than normal, and the stickup of foil gauge is larger on test result impact, can not on-the-spot test etc. problem.Air pressure indirectly testing method exists signal to noise ratio (S/N ratio) low, can not realize the beater mechanism of nonnitrogenous air cavity such as is tested at the problem.
Summary of the invention
The object of the invention is to provide a kind of for the deficiencies in the prior art and guarantee under the complete condition of beater mechanism, the impact property parameter of impact mechanism is carried out the online accurately beater mechanism impact property test macro of test.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of beater mechanism impact property test macro, comprise piezoelectric acceleration transducer, charge amplifier, data acquisition unit and processor, described piezoelectric acceleration transducer is connected with the piston end of beater mechanism by adapter, and piezoelectric acceleration transducer obtains piston end acceleration of motion signal; Described charge amplifier amplifies the piston movement acceleration signal that described piezoelectric acceleration transducer obtains, and enters processor by described data acquisition unit collection, and processor is processed data by relevant program.
The pressure hydraulic fluid port (P) of described beater mechanism is connected with pressure transducer, the signal end of described pressure transducer is connected with described data acquisition unit, between described pressure hydraulic fluid port (P) and the flow speed control valve flow sensor is installed, the signal end of described flow sensor is connected with described data acquisition unit.
Adopt said structure, the present invention is connected to piezoelectric acceleration transducer the rear end of piston, the acceleration of test piston, with the data of gained after charge amplifier amplifies, input processor, by relative program data are carried out integration again, draw the movement velocity of piston, the relational expression of Negotiation speed and energy draws the impact property of beater mechanism, because the acceleration of motion of piston is relevant with the working pressure of knocker, by the working pressure of test knocker, pressure changed with measured acceleration comparing, but the correctness of the result of validation test and variation tendency.The piezoelectric acceleration transducer quality is little, and dynamic property is good, and precision is high, can guarantee preferably the precision of test result.
Description of drawings
Fig. 1 is schematic diagram of the present invention;
Embodiment
Below in conjunction with accompanying drawing, further describe the embodiment of this patent.
As shown in Figure 1, a kind of beater mechanism impact property test macro comprises adapter 2, piezoelectric acceleration transducer 3, and charge amplifier 4, pressure transducer 5, data acquisition unit 6, processor 7, flow sensor 8 forms.When piston 1 motion, piezoelectric acceleration transducer 3 obtains the piston movement acceleration signal, after charge amplifier 4 amplifies, enter processor 7 through data acquisition unit 6, then by relevant program data are carried out integration, obtain the movement velocity of piston, the relation of Negotiation speed and energy just can obtain impact energy and the frequency of impact of hydraulic impact mechanism A.Because the acceleration of motion of piston is relevant with the working pressure of knocker, by the working pressure of test beater mechanism A, pressure variation and measured acceleration are compared, but the correctness of the result of validation test and variation tendency.Piezoelectric acceleration transducer 3 quality are little, and dynamic property is good, and precision is high, can guarantee preferably the precision of test result.
