Description
Technical field
The invention belongs to connector test technical field, and in particular to a kind of connector durability auto testing instrument and test
Method.
Background technology
In order to examine the multinomial performance of connector, connector needs to be required according to standard after producing, and carries out multinomial
Experiment, the endurancing of connector is exactly one therein, it is desirable to which what connector was subjected to plugging together and separating as defined in standard follows
Ring number, general connector cycle-index is 500 times at present, even more more according to different use occasions.Connect for screw-type
The connector that connects is tightened with torque spanner, then separated, this process needs to repeat 500 times, it is necessary to headstock is docked.At present this
By being accomplished manually, completing 500 connection separation at least needs three, four hours, is wasted time and energy for operating personnel for item experiment,
This experiment is affected for repeatability in addition, the problems such as artificial fatigue, counting error and maloperation be present, the result of experiment is by artificial
Factor has a great influence.
The content of the invention
In order to solve the artificial multinomial problem for carrying out endurancing, it is an object of the invention to provide a kind of connector is resistance to
Long property auto testing instrument and method of testing, the process that connector is screwed and separated is completed by the tester, while is accurately counted
Number, excludes influence of the human factor to experiment, and whole experiment realizes automation.
To achieve these goals, the technical solution adopted by the present invention is：
A kind of connector durability auto testing instrument, including hollow shaft DC low-speed motor 2, it is low to be arranged on hollow shaft direct current

Device 4 controls the lifting of elevating lever 14, and connector body 13 is fixed on the driving end of torque spanner 11, and spring 9 is connector
Plug 12 and connector body 13 provide thrust to inserting；Base 6 is fixed on hollow shaft DC low-speed motor 2, fixed on base 6
Six square sockets 10 in having, interior six square socket 10 is adapted with the six square nuts size of connector plug 12, when hollow shaft DC low-speed
The six square nuts of base 6, interior six square socket 10 and connector plug 12 are driven to be rotated when motor 2 rotates, connector plug
12 and the inserted position of connector body 13 alignment；
The method of testing of the connector durability auto testing instrument, operating personnel are on touch-screen 5 to testing every time
Rotating cycle, rotary speed and screw number and set, controller 4 controls rotating speed, steering and the start and stop of DC low-speed motor 2
Time；The connector body 13 for needing to test is arranged on the driving end of torque spanner 11 during experiment, interior base 8 and central shaft
After 7 tighten, spring 9 is put into, places into connector plug 12, interior six square socket 10 is then enclosed on the side's spiral shell of connector plug 12 6
Female outside, is screwed on base 6；After connector body 13 and connector plug 12 are aligned, elevating lever 14 drives
Torque spanner 11 declines a segment distance under the control of controller 4 so that spring 9 is in compressive state, and spring 9 will carry after compressing
The thrust fed to, it is that connector body 13 and connector plug 12 to inserting provide thrust；During work, start button is pressed,
Base 6 rotates in company with hollow shaft DC low-speed motor 2, and rotary encoder 3 detects the rotation circle of hollow shaft DC low-speed motor 2
Number, controller 4 is fed back to by transmission line by above-mentioned signal；The rotate counterclockwise first of hollow shaft DC low-speed motor 2, which reaches, to be set
The fixed number of turns, stop, then hollow shaft DC low-speed motor 2 is rotated clockwise to the circle of setting under the control of control system 4
Number, stop, repeating above-mentioned steps；Because interior six square socket 10 is fixed on base 6, six side's spiral shells of connector plug 12 are driven
Mother rotates with hollow shaft DC low-speed motor 2, is then that simulation people will when hollow shaft DC low-speed 2 rotate counterclockwise of motor
Connector plug 12 and connector body 13 rotate the process plugged together with torque spanner 11, when hollow shaft DC low-speed motor 2 is suitable
When hour hands rotate, then be simulation people with torque spanner 11 by the process of connector plug 12 and the rotating separation of connector body 13；
The number of turns that hollow shaft DC low-speed motor 2 rotates and reverse reach setting screw separation number after, at this moment connector plug 12
The rotation that setting number is also just completed with connector body 13 is plugged together and separated, and elevating lever 14 drives torque spanner 11 to rise,
Experiment is completed.
Compared to the prior art the present invention, has the following advantages that：
Automation, the standardization of connector endurancing are realized, operating personnel are solved to releasing from heavy experiment
Come, exclude influence of the human factor to experiment, improve the accuracy of experiment.
Brief description of the drawings
Fig. 1 is tester working state figure of the present invention.
Fig. 2 is the partial enlarged drawing of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, controller 4 is connected with touch-screen 5 so that the rotation that operating personnel can be to testing every time
The number of turns, rotary speed and screw number and set.Controller 4 is connected with hollow shaft DC low-speed motor 2 by wire, can be with
Control rotating speed, steering and the start-stop time of hollow shaft DC low-speed motor 2.The connector body 13 for needing to test is pacified during experiment
On the driving end of torque spanner 11, after interior base 8 is tightened with central shaft 7, spring 9 is put into, places into connector plug 12,
Then interior six square socket 10 is enclosed on to the outside of the six square nuts of connector plug 12, be screwed on base 6.By connector
After socket 13 and connector plug 12 are aligned, elevating lever 14 drive torque spanner 11 decline under the control of controller 4 one section away from
From so that spring 9 is in compressive state, and spring 9 will provide upward thrust after compressing, and be inserted for connector body 13 and connector
First 12 docking provides thrust.During work, start button is pressed, base 6 rotates in company with hollow shaft DC low-speed motor 2, rotation
Encoder 3 detects the rotating cycle of hollow shaft DC low-speed motor 2, and above-mentioned signal is fed back into controller 4 by transmission line；It is empty
The rotate counterclockwise first of mandrel DC low-speed motor 2 reaches the number of turns of setting, stops, then hollow shaft DC low-speed motor 2 exists
The number of turns of setting is rotated clockwise under the control of control system 4, stops, repeating above-mentioned steps；Due to interior six square socket 10
On base 6, the six square nuts of connector plug 12 can be driven as hollow shaft DC low-speed motor 2 rotates, when hollow
Then it is that connector plug 12 and connector body 13 are used torque spanner by simulation people during axle DC low-speed 2 rotate counterclockwise of motor
The process that 11 rotations plug together, then it is that simulation people will even with torque spanner 11 when hollow shaft DC low-speed motor 2 turns clockwise
Connect the process of device plug 12 and the rotating separation of connector body 13；The number of turns that hollow shaft DC low-speed motor 2 rotates and reverse arrives
Up to setting screw separation number after, at this moment connector plug 12 and connector body 13 also just complete setting number rotation
Plug together and separate, elevating lever 14 drives torque spanner 11 to rise, and experiment is completed.
Because connector plug 12 and connector body 13 are during rotation plugs together and separates, the meeting of connector plug 12
Move up and down a segment distance, so in design during six square sockets 10, interior six square socket will have enough height, ensure connector
The six square nuts of plug 12 are stuck in interior six square sockets all the time.
Purpose using torque spanner is to ensure that connector plug 12 and socket 13 reach standard regulation when rotation plugs together
Screw-down torque requirement.
