Technical solution of the present invention is described in further detail with reference to embodiment and accompanying drawing, but the protection model of the present invention
Enclose and be not limited to the embodiment.
As shown in Fig. 1 to 5, a kind of device in automatic detection coil spring life-span, including organic frame installs fixed machine in frame
Structure, testing agency and Material moving device.
Fixed mechanism includes fixed plate 1, fixed column 19, the first fixed seat 16, the second fixed seat 20 and three clamping hydraulics
Cylinder 8, fixed plate 1 and horizontal plane and offers through hole, and fixed column 19, the first fixed seat 16 and the second fixed seat 20 are pacified
At the diverse location on the leading flank of fixed plate 1.There are one and fixed column in first fixed seat 16 and the second fixed seat 20
19 parallel fixing axles, and both center is respectively positioned in same horizontal line.Before being provided with the piston rod of compression hydraulic cylinder 8
End face is in the gland 7 of arc surface, and towards through hole, and the distance between any two compression hydraulic cylinder 8 is equal.The
One fixed seat 16 is used to place coil spring 17 to be checked, places quantity and is no less than 5, and the second fixed seat 20 is used for placement and detected
The coil spring 17 finished.
Testing agency is located at the trailing flank of fixed plate 1, and it includes the 3rd slide unit 4, rotating shaft 18, torsion torque sensor and the first electricity
Machine 11.3rd slide unit 4 is slidedly assemblied in frame（It is not shown）It is upper and can the 3rd hydraulic cylinder 12 driving lower edge perpendicular to consolidating
The direction motion of fixed board 1.First motor 11 is arranged on the 3rd slide unit 4, and the main shaft of the first motor 11 is sequentially connected shaft coupling（Not
Show）, torsion torque sensor（It is not shown）With rotating shaft 18.3rd slide unit 4 can drive rotating shaft 18 to make rotating shaft through through hole when moving
18 are located at three centers for stepping up hydraulic cylinder.Rotating shaft 18 is provided with the baffle plate 18.1 or lever radially stretched out.
Material moving device is located at the leading flank of fixed plate 1, and it includes the first slide unit 6, the second slide unit 2, the 4th slide unit 3 and the 5th
Slide unit 5, and driven respectively by first hydraulic cylinder 14, second hydraulic cylinder 10, the 4th hydraulic cylinder 13 and the 5th hydraulic cylinder 9.First
Slide unit 6 is slidedly assemblied in frame and can be under the driving of first hydraulic cylinder 14 along horizontal motion.4th slide unit 3 slides dress
Fit on the first slide unit 6 and can be vertically moving under the driving of the 4th hydraulic cylinder 13.Second slide unit 2 is slidedly assemblied in

Air-actuated jaw 15 is installed.
In the present embodiment, the mounting means of all slide units can be installed by the way of slide rail or lead, can be real
Now moved along a straight line along a direction, mounting means and mechanism belong to prior art, repeat no more.Leading flank refers in work shape
Common face under state, trailing flank is then seldom to meet.
The operation principle and process of the present invention
First coil spring 17 to be detected is sequentially placed onto the first fixed seat 16, then the related slide unit in Material moving device
Motion causes air-actuated jaw 15 to be located exactly at the front for the coil spring 17 being placed in fixed seat.Air-actuated jaw 15 is by coil spring 17
After clamping, the related slide unit in Material moving device is moved again so that air-actuated jaw 15 is located exactly at the front of rotating shaft 18.Now
Three slide units 4, which travel forward, makes rotating shaft 18 through through hole and positioned at the center of coil spring 17, and then starting the first motor 11 makes to turn
The inner 17.1 that baffle plate 18.1 during the rotation of axle 18 thereon hooks coil spring 17 just drives it together to rotate.Coil spring 17 is rotated
When, its outer end 17.2 can hook fixed column 19 just, and now the first motor 11 suspends.Then three step up hydraulic cylinder piston
Bar stretches out to the direction of rotating shaft 18 simultaneously causes the front end face of gland 7 is contacted with the lateral wall of coil spring 17 to roll up bullet so as to constrain
The position of spring 17.And then air-actuated jaw 15 is withdrawn from, and the first motor 11 is again started up driving the inner 17.1 of coil spring 17 to reverse,
Now torsion torque sensor records a torsion numerical value at regular intervals.When coil spring 17 is torqued at utmost, the first electricity
Machine 11 suspends, and coil spring 17 recovers original state under elastic potential energy effect, and now torsion torque sensor is spaced same time again
A numerical value is recorded, this process is denoted as a cycle.The twist process is constantly repeated, until what is detected in some cycle
When torque magnitude drops to some setting value in reseting procedure, judge that the coil spring 17 is scrapped, now the time used be designated as this
The service life of coil spring 17.Because coil spring 17 is still intact, now the coil spring finished will be detected using air-actuated jaw 15
17 remove and are placed into the second fixed seat 20, then capture next coil spring 17 to be detected from the first fixed seat 16 again
Carry out second of detection operation.
In test, that outermost circle of coil spring can deform therefore can cause occur phase with gland front end face
To displacement, therefore in order to reduce frictional force, groove is opened up on front end face, ball or guide wheel are set in a groove, and make ball
Or a part for guide wheel is located at outside front end face, consequently, it is possible to which the outer ring of coil spring can be contacted with ball or guide wheel.
Above-described embodiment is preferably embodiment, but embodiments of the present invention are not by above-described embodiment of the invention
Limitation, other any Spirit Essences without departing from the present invention and the change made under principle, modification, replacement, combine, simplification,
Equivalent substitute mode is should be, is included within protection scope of the present invention.
