When hollow axle DC low-speed motor 2 turns clockwise, then it is that adapter is inserted by simulation people with torque spanner 11
12 and the process of connector body 13 rotating separation；Hollow axle DC low-speed motor 2 rotates and reverse
After what number of turns arrival set screws separation number of times, at this moment connector plug 12 and connector body 13 are also the completeest
The rotation having become set point number plugs together and separates, and elevating lever 14 drives torque spanner 11 to rise, and test completes.
Compared to the prior art the present invention, has the advantage that
Achieve the automatization of adapter endurancing, standardization, by operator from heavy test
Free, get rid of the anthropic factor impact on test, improve the accuracy of test.
Accompanying drawing explanation
Fig. 1 is tester working state figure of the present invention.
Fig. 2 is the partial enlarged drawing of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail.
As depicted in figs. 1 and 2, controller 4 is connected with touch screen 5 so that operator can be to every time
Rotating cycle, the rotary speed of test and screw number of times and be set.Controller 4 and hollow axle DC low-speed
Motor 2 is connected by wire, can control the rotating speed of hollow axle DC low-speed motor 2, when turning to start and stop
Between.During test, the connector body 13 needing test is arranged on the driving end of torque spanner 11, inner bottom
After seat 8 and central shaft 7 are tightened, put into spring 9, place into connector plug 12, then by interior six square sets
Cylinder 10 is enclosed within the outside of connector plug 12 6 square nut, is screwed on base 6.By adapter
After socket 13 and connector plug 12 alignment, elevating lever 14 drives torque spanner 11 in the control of controller 4
System is lower declines a segment distance so that spring 9 is in compressive state, will provide pushing away upwards after spring 9 compression
Power, the docking for connector body 13 and connector plug 12 provides thrust.During work, press startup by
Button, base 6 rotates in company with hollow axle DC low-speed motor 2, and it is low that rotary encoder 3 detects hollow axle direct current
The rotating cycle of speed motor 2, feeds back to controller 4 by transmission line by above-mentioned signal；Hollow axle DC low-speed
First motor 2 rotates counterclockwise to reach the number of turns of setting, stops, and then hollow axle DC low-speed motor 2 exists
It is rotated clockwise to the number of turns set under the control of control system 4, stops, repeating above-mentioned steps；Due to
Interior six square sockets 10 are arranged on base 6, and six square nuts of connector plug 12 can be driven along with hollow axle
DC low-speed motor 2 rotates, and when hollow axle DC low-speed motor 2 rotates counterclockwise, is then that simulation people will
Connector plug 12 and connector body 13 rotate the process plugged together, when hollow axle direct current with torque spanner 11
When slowspeed machine 2 turns clockwise, then it is that simulation people and connects connector plug 12 with torque spanner 11
The process of device socket 13 rotating separation；The number of turns that hollow axle DC low-speed motor 2 rotates and reverse arrives and sets
Screw separation number of times after, at this moment connector plug 12 and connector body 13 the most just complete set point number
Rotation plug together and separate, elevating lever 14 drives torque spanner 11 to rise, and test completes.
Owing to connector plug 12 and connector body 13 are during rotation plugs together and separates, adapter
Plug 12 can move up and down a segment distance, so in design during six square sockets 10, interior six square sockets to have
Enough height, it is ensured that six square nuts of connector plug 12 are stuck in interior six square sockets all the time.
The purpose using torque spanner is to ensure that connector plug 12 and socket 13 reach mark when rotation plugs together
The requirement of the screw-down torque of quasi-regulation.
