Chinese patent CN102840934A discloses a kind of change-over switch contact pressure detection equipment, including the workbench for positioning and clamping permutator, with the signal connection device that the patch panel of permutator electrically connects, the traction measurement apparatus of tractive permutator static contact.The permutator to be measured by being automatically positioned clamping, signal connection device is made to be connected connection measure loop with permutator, mobile traction measurement apparatus makes the static contact that jaw measures assembly traction permutator, static contact is separated with moving contact, measure loop is made to disconnect, obtain this loop by data acquisition unit and disconnect the pulling force numerical value of moment, be the change-over switch contact pressure value detected.But this application is intended to the contact pressure measuring whole permutator, it has been now that what to be assembled into that finished product and this patent measure is N group data, the error in data so measured is bigger, for needing the product accurately controlling contact end pressure cannot play the purpose detecting in advance and improving, the measurement running part of known invention is skid transmission, such transmission stability is poor, stress bigger or uneven time easily beat and driving error is bigger, it is easy to measurement result is produced very big interference.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and the moving contact end pressure testing agency of a kind of simple in construction, compatible strong, convenient for maintaining is provided.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of moving contact end pressure testing agency, including:
Placing the positioning fixture of moving contact to be measured, be movably connected on base, the lower section of base is additionally provided with the horizontal adjustment regulating its horizontal level and supports,
It is connected to the leading screw of servomotor, leading screw is provided with the pressure head moved up and down along screw mandrel, adopt leading screw ensure the steady of transmission and precisely, reduce the error that measurement system causes,
Display with data processing module, receive the pressure that detects of pressure head and show, data processing module automatic clear also records current scale chi coordinate, data processing module provides instruction simultaneously, servomotor remains in operation, whole test formally starts, until when pressure stroke reaches preset value down, display is when front contact end pressure automatically.
Described pressure head is built-in with pressure transducer, leading screw controls pressure head and presses to preset value, display shows when front contact end pressure data processing module simultaneously provides instruction, servomotor quits work, back to electricity after pause Preset Time, servomotor antiport, band dynamic head moves up, and returns initial position.Detection is complete every time, and data processing module automatically saves test result and date, can have access to conventional testing result from display at any time, it is simple to follow the trail of management and control.
The upper and lower side of described leading screw is respectively provided with one piece of stop tab preventing ram movement from exceeding stroke.
It is additionally provided with the emergency stop button controlling servomotor emergency power off.
It is additionally provided with transparent shield outside described positioning fixture.
Described positioning fixture is movably connected on base through screw, carries out dismounting and change according to the size of moving contact to be measured.
With rule on described leading screw, it is possible to allow the location of the open-and-shut confirmation pressure stroke of user, play and the purpose of data processing module double check calibration.
Described positioning fixture coordinates for being completely reversed with moving contact to be measured, i.e. master mold on the similar mould of base, the similar male model of part, such cooperation makes the part when measuring be completely restrained, so, measurement error is little, and part stress is uniform, and part will not cause unnecessary damage because of measurement.
The present invention adopts lead screw transmission, stable drive is accurate, complete analog switch is the end pressure of single moving contact under "on" position, there is registration, measurement error is little and plays the effect prevented in advance, so can reduce the impact on product to be tested measurement result of the beating during transmission of equipment own when positioning contact pressure stroke and the excess of stroke.Just measure when moving contact or single component whether it meets designing requirement originally, meet, continue to assemble, do not meet, be classified as defective products, do not allow it continue to subsequent processing, reduce the quality problem caused because single component is defective.
Compared with prior art, the present invention has the feature such as simple in construction, strong, energy consumption is low, cost is few, effect is strong, replacement cycle length, convenient for maintaining intelligent, compatible, and for ensureing that the quality that chopper is good provides better detection prevention platform.
