Abstract
A kind of compressor arm demarcates loading test device, it is to produce loading by computer motion control, and measuring each measuring point by strain transducer strains.The device is easy to operate automatic, is suitable for the calibration load test of various compressor arms.
Description
Technical field：
The present invention relates to a kind of compressor arm test device, specifically a kind of compressor arm calibration loading test device.
Background technology：
Structural member on space satellite, through carrying out structure connection frequently with compression release device, wherein on compressor arm
Pretightning force needs to demarcate, generally use spanner manual rotation clamp nut, obtains nut rotation angle pass corresponding with pretightning force
System, but manual loading easily produces deviation, uneven stress, when compared with big load nut is blocked with screw thread, causes to press
Tight bar failure, control accuracy and operating characteristics are poor.
The content of the invention：
The purpose of the present invention is to solve the shortcomings of the prior art and provide a kind of compressor arm calibration loading test device.Should
Device, which is adopted to computerized control, carries out loading measurement, high certainty of measurement, and the degree of automation is high, easy to operate.
Technical scheme：
Loaded by computer controlled motion control card, realized by motor and rotatably compress nut, pass through strain sensing
Device measures each measuring point stress, and computer automatically processes rating test result.
The beneficial effects of the invention are as follows：Compared with the prior art, the present invention is a kind of based on the control of computer controlled motion
Block the automatic testing equipment loaded, high certainty of measurement, the degree of automation is high, easy to operate.
Brief description of the drawings：
Fig. 1 is the structure diagram of the present invention.
Marked in figure：1 compressor arm holds end, 2 frames, 3 load sleeves, 4 compressor arms, 5 clamp nuts, on 6 pressed seats
Portion, 7 strain transducers, 8 pressed seat lower parts, 9 reverse loading arm, 10 motion control cards, 11 computers.
Embodiment：
A kind of as shown in Figure 1, compressor arm calibration loading test device.End, 2 frames, 3 loading sleeves are held including 1 compressor arm
Cylinder, 4 compressor arms, 5 clamp nuts, 6 pressed seat tops, 7 strain transducers, 8 pressed seat lower parts, 9 reverse loading arm, 10 movements
Control card, 11 computers.
The pressed seat top 6, pressed seat lower part 8 are fixed on loading frame 2 after being connected by compressor arm 4, are compressed
4 upper end of bar holds end 1 by compressor arm and clamps；Reverse loading arm 9 and apply moment of torsion generation pressure to clamp nut 5 by load sleeve 3
Tight effect；Controlled by computer 11 by motion control card 10 and reverse loading arm 9；Strain transducer 7 is connected to computer 11；Meter
The processing of calculation machine 11 obtains the thrust of compressor arm 4.
The compressor arm demarcates loading test device operation principle：Motion control card drives torsion under the control of the computer
Turn loading arm, compression rating test can be carried out according to measurement needs, strain transducer result of the test is automatically saved to computer
In.
