Below in conjunction with embodiment and accompanying drawing, technical solutions of the utility model are described in further detail, but protection domain of the present utility model is not limited to described embodiment.
As shown in Fig. 1 to 5, the device in a kind of automatic detection coil spring life-span, includes frame, mechanism for installing, testing agency and Material moving device in frame.
Fixed mechanism comprises fixed head 1, fixed leg 19, first holder 16, second holder 20 and three compression hydraulic cylinder 8, fixed head 1 is with horizontal plane and offer through hole, and fixed leg 19, first holder 16 and the second holder 20 are installed in the diverse location place on the leading flank of fixed head 1.First holder 16 all has a stationary shaft parallel with fixed leg 19 with on the second holder 20, and both centers are all positioned on same level line.The piston rod of compression hydraulic cylinder 8 is provided with the gland 7 that front end face is arc surface, and all towards through hole, and distance between any two compression hydraulic cylinder 8 is equal.First holder 16, for placing coil spring 17 to be checked, places quantity and be no less than 5, and the second holder 20 detects complete coil spring 17 for placing.
Testing agency is positioned at the trailing flank of fixed head 1, and it comprises the 3rd slide unit 4, rotating shaft 18, torsion torque sensor and the first motor 11.3rd slide unit 4 is slidedly assemblied on frame (not shown) and also can moves along the direction perpendicular to fixed head 1 under the driving of the 3rd hydraulic cylinder 12.First motor 11 is arranged on the 3rd slide unit 4, and the main shaft of the first motor 11 connects shaft coupling (not shown), torsion torque sensor (not shown) and rotating shaft 18 successively.3rd slide unit 4 can drive rotating shaft 18 through through hole make rotating shaft 18 be positioned at center that three are stepped up hydraulic cylinder when moving.Rotating shaft 18 is provided with the baffle plate 18.1 or lever that radially stretch out.
Material moving device is positioned at the leading flank of fixed head 1, and it comprises the first slide unit 6, second slide unit 2, the 4th slide unit 3 and the 5th slide unit 5, and drives respectively by the 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 also can moves in the horizontal direction under the first hydraulic cylinder 14 drives.4th slide unit 3 is slidedly assemblied on the first slide unit 6 and also vertically can moves under the 4th hydraulic cylinder 13 drives.Second slide unit 2 is slidedly assemblied on the 4th slide unit 3 and also can moves along the direction being parallel to rotating shaft 18 axis under the driving of the second hydraulic cylinder 10.5th slide unit 5 slides and is transferred on the second slide unit 2 and can moves in the same way with the second slide unit 2 under the driving of the 5th hydraulic cylinder 9, and air-actuated jaw 15 installed by the 5th slide unit 5.

Principle of work of the present utility model and process
First be placed on the first holder 16 successively by coil spring 17 to be detected, the relevant slide unit motion then in Material moving device makes air-actuated jaw 15 just be positioned to be placed on the front of the coil spring 17 on holder.After coil spring 17 is clamped by air-actuated jaw 15, the relevant slide unit in Material moving device moves the front making air-actuated jaw 15 just be positioned at rotating shaft 18 again.Now the 3rd slide unit 4 travels forward and makes rotating shaft 18 through through hole and be positioned at the central authorities of coil spring 17, and the inner 17.1 that the baffle plate 18.1 then started when the first motor 11 makes rotating shaft 18 rotate on it hooks coil spring 17 just drives it together to rotate.When coil spring 17 rotates, fixed leg 19 can be hooked just in its outer end 17.2, and now the first motor 11 suspends.Then three piston rods stepping up hydraulic cylinder stretch out to rotating shaft 18 direction simultaneously and make the front end face of gland 7 contact with the lateral wall of coil spring 17 thus retrain the position of coil spring 17.And then air-actuated jaw 15 is withdrawn from, and the inner 17.1 that the first motor 11 starts drive coil spring 17 is again reversed, and now torsion torque sensor records a torsion numerical value at set intervals.When coil spring 17 is torqued at utmost, the first motor 11 suspends, and coil spring 17 recovers original state under elastic potential energy effect, and now torsion torque sensor interval same time record numerical value again, is denoted as one-period by this process.This twist process constantly repeats, until when in the reseting procedure detected in certain cycle, torque magnitude drops to some setting values, judge that this coil spring 17 is scrapped, now the time used is designated as the service life of this coil spring 17.Because coil spring 17 is still intact, now utilize air-actuated jaw 15 that the complete coil spring 17 of detection is taken off and is placed on the second holder 20, and then capture next coil spring 17 to be detected from the first holder 16 and carry out second time and detect operation.
When testing, that circle outermost of coil spring can deform and therefore can cause and gland front end face generation relative displacement, therefore in order to reduce friction, front end face offers groove, ball or guide wheel are set in a groove, and make a part for ball or guide wheel be positioned at outside front end face, thus, the outer ring of coil spring can contact with ball or guide wheel.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
