In order to realize the purpose of the utility model, said airplane wheel nut self-locking moment test board comprises the work top anchor clamps that are located on the lathe; Said work top anchor clamps match with the rotary clamp that comprises standard bolt; And be provided with fixingly by the mount pad of side nut, wherein, said work top anchor clamps are connected with the force transducer that is connected with microcomputer, displacement transducer, limit switch; Wherein, After standard bolt being put in the tested nut, measure through torque sensor and displacement transducer and to be screwed into moment M and depth H, and then judge whether tested nut is qualified.
Further, preferred construction is, it carries out positive and negative, stall control to the motor on the said lathe by said microcomputer control, and wherein, said motor links together through main shaft and said standard bolt.
Further, preferred construction is that said microcomputer is provided with moment display, displacement display, and it also is provided with hummer, is used for when said nut is defective, sending alerting signal.
Further, preferred construction is that after said standard bolt left tested nut, main shaft was understood automatic stall, stopped rising.
The utility model has measuring accuracy height, fireballing technique effect after having taked technique scheme, satisfied the demand of existing airplane wheel nut to testing apparatus and measuring technology, has extraordinary technique effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is carried out detailed description, so that the above-mentioned advantage of the utility model is clearer and more definite.
Fig. 1 is the synoptic diagram of the utility model airplane wheel nut self-locking moment method of testing.
Embodiment
The principle of work of the utility model is described below:
The first, nut is with after bolt is connected, and the bolt that has exposes 2 teeth (promptly 2 buckleing), and what have does not expose, nut end face and bolt breech face one flat getting final product.Anti-nutting under this condition is surveyed it and is instead twisted moment.It is qualified to judge whether by the moment size.
The second, according to above-mentioned principle, we can test the moment of anti-nutting from the bolt, on tapping machine, drilling machine, milling machine, all can accomplish.At first, on the tapping machine worktable, design the anchor clamps that can rotate slightly (clamping device), and be connected with torque sensor.Nut is fixed in the anchor clamps.Pitch adjusting mechanism of design is loaded onto a certain standard bolt on the main shaft of tapping machine, constitutes a unit head.When main axis rotation, the automatic make-up of bolt ability also screws in nut.
According to technical requirement, the relative position of control bolts and nuts to bit reversal, makes bolt leave nut.Measure the anti-moment of twisting of nut by torque sensor.
All processes is by computer control, and whether qualifiedly can judge, controls the nut that the go-on-go box is collected acceptance or rejection at last.Simultaneously, can also show (pilot lamp, quantity show) and warning.In case of necessity, can also print the inspection statistics table by mini-printer.
Fig. 1 is the synoptic diagram of the utility model airplane wheel nut self-locking moment method of testing.
As shown in the figure, this process schematic representation has disclosed the main synoptic diagram of the utility model airplane wheel nut self-locking moment test board and method of testing.
Wherein, said airplane wheel nut self-locking moment test board comprises the work top anchor clamps that are located on the lathe; Said work top anchor clamps match with the rotary clamp that comprises standard bolt; And be provided with fixingly by the mount pad of side nut, wherein, said work top anchor clamps are connected with the force transducer that is connected with microcomputer, displacement transducer, limit switch; Wherein, After standard bolt being put in the tested nut, be screwed into moment M and depth H through measuring of torque sensor and displacement transducer, and then judge whether tested nut is qualified.
And it carries out positive and negative, stall control to the motor on the said lathe by said microcomputer control, and wherein, said motor links together through main shaft and said standard bolt.
In addition, said microcomputer is provided with moment display, displacement display, and it also is provided with hummer, is used for when said nut is defective, sending alerting signal.
In addition, after said standard bolt left tested nut, main shaft was understood automatic stall, is stopped rising.
Describe to the method for the utility model below:
Like figure, wherein, positive and negative, the stall of machine tool chief axis is by microcomputer-controlled.
When computer booting, self check and set piece number, manual work can be put into tested nut after more finishing changing standard bolt and tested nut mount pad.
And in a single day staff is forced off the table, and dress all has the rotary clamp of standard bolt just to change immediately, descends.
In addition, when standard bolt touches tested nut, make-up and the automatic make-up of pitch adjusting mechanism meeting, then the pitch by tested nut feeds, screws in.
At this moment, torque sensor and displacement transducer are constantly measured and are screwed into moment M and depth H, send computing machine to.
When reaching prescribed depth Hmax, main shaft counter-rotating, standard bolt begin to rise.
Then measure the moment of back-outing (self-locking moment) M ' and corresponding depth H '.
Remove rear (Ho), by computer judges
Mmin＜M＜Mmax and Mmin＜M '＜Mmax;
Whether set up.Set up and be certified products; Be false and be unacceptable product.When standard bolt leaves tested nut after several seconds, main shaft can automatic stall, stop rising.
And when taking out qualified nut, computing machine can be ordered the action of go-on-go box valve electromagnet, closes defective district passage vertically downward, makes qualified nut fall into qualified district;
In addition, when taking out defective nut, computing machine can order go-on-go box dodge gate electromagnet to be failure to actuate, and makes defective nut lean on gravity directly to fall into defective district.
Simultaneously, computing machine carries out the counting of certified products and unacceptable product respectively.Then carry out the test of next nut.
Print if desired, can before putting into next tested nut, print.
The utility model has measuring accuracy height, fireballing technique effect after having taked technique scheme, satisfied the demand of existing airplane wheel nut to testing apparatus and measuring technology, has extraordinary technique effect.
It should be noted that; Above-mentioned specific embodiment only is exemplary; Under the above-mentioned instruction of the utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improve or distortion drops in the protection domain of the utility model.
