The utility model discloses the beneficial effect who reaches: can realize that roll spring is automatic fixed, need not manpower intervention to has better fixed effect. The preceding terminal surface of fixed head is the arc surface, can with the outer wall looks adaptation of the book spring that will fix to play better fixed effect. The fixed column can remove at will to centre -to -centre spacing between adjustment fixed column and the pivot is with this book spring fixed that satisfies different specification and dimension.
Description
Technical field
The utility model relates to plane scroll spring field tests, particularly a kind of instrument can testing the plane scroll spring life-span.
Background technology
Coil spring has another name called clockwork spring, is the spring of helix in a plane, is turned to a kind of spring of planar spiral by special material.Spring one end is fixed, material moment by bending after other end action torque, produces elasticity of flexure distortion, and thus spring produces at own layer and reverses.Size and the moment of torsion of its deformation angle are directly proportional, and have high torsion, with the twisting resistance of multi-angle apart from thus apply to the mechanism of long-time work done, have the characteristic of indefatigability, it uses similar torsion spring.The main performance index of coil spring is peak torque, minimal torque and service life etc.
The mode of test coil spring service life often adopts its inner of driven by motor repeatedly to rotate, but the coil spring installation method taked in prior art is manually installed on test machine by manpower intervention then to start test.The limitation of this method is to need to install manually, and waste time and energy inefficiency, is difficult to the requirement adapting to automatic test.
Utility model content
The utility model proposes a kind of stationary installation be used on coil spring life testing machine, automatically can fix coil spring fast.
Technical solution of the present utility model: a kind of stationary installation be used on coil spring life testing machine, comprises frame, it is characterized in that: also comprise fixed head, rotating shaft, fixed leg and at least two compression hydraulic cylinder; Fixed head and horizontal plane, rotating shaft and fixed leg are all vertical with the plate face of fixed head; Fixed leg can move on fixed head, and rotating shaft is provided with the baffle plate or lever that radially stretch out; The piston rod of compression hydraulic cylinder is provided with gland, and all towards rotating shaft.
Preferably, the quantity of compression hydraulic cylinder is three, and distance between any two hydraulic cylinders is equal.
Preferably, baffle plate or lever are bending.
Preferably, the front end face of the gland in compression hydraulic cylinder is the arc surface concaved.
The beneficial effect that the utility model reaches:
1. can realize coil spring automatically to fix, without the need to manpower intervention, and there is good fixed effect.
2. the front end face of gland is arc surface, can be suitable with the outer wall of the coil spring that will fix, thus plays better fixed effect.
3. fixed leg can arbitrarily movement, thus the centre distance between adjustment fixed leg and rotating shaft, meet the fixing of the coil spring of different specification size with this.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of stereographic map of test machine;
Accompanying drawing 2 is front views of a kind of test machine;
Accompanying drawing 3 is the structural representations in the utility model.
Reference numeral:
1 fixed head; 7 glands; 8 compression hydraulic cylinder; 11 first motors; 15 air-actuated jaws; 17 coil springs; 17.1 is inner; 17.2 outer ends; 18 rotating shafts; 18.1 baffle plates; 19 fixed legs.
Embodiment
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 Figures 1 to 3, a kind of stationary installation be used on coil spring life testing machine, includes frame, mechanism for installing, testing agency and Material moving device in frame.
Fixed mechanism comprises fixed head 1, rotating shaft 18, fixed leg 19 and three compression hydraulic cylinder 8; Fixed head 1 and horizontal plane, rotating shaft 18 and fixed leg 19 are all vertical with the plate face of fixed head 1; Fixed leg 19 can move on fixed head, and rotating shaft is provided with the baffle plate 18.1 radially stretched out, and baffle plate is bending.The piston rod of compression hydraulic cylinder is provided with gland 7, the front end face of gland is the arc surface of indent, and all towards rotating shaft.The centre distance of fixed leg and rotating shaft is changed by the position of mobile fixed leg on fixed head, thus the coil spring of other different size adaptive.
Testing agency is positioned at the trailing flank of fixed head 1, and it comprises torsion torque sensor and the first motor 11.The main shaft of the first motor 11 connects shaft coupling (not shown), torsion torque sensor (not shown) and rotating shaft 18 successively.
Material moving device is positioned at the leading flank of fixed head 1, and it comprises respectively along the slipway mechanism that X/Y/Z direction of principal axis moves, this slipway mechanism can be installed air-actuated jaw 15.
In the present embodiment, the mounting means of all slide units can adopt the mode of slide rail or guidepost to install, and all can realize along a direction rectilinear motion, mounting means and mechanism all belong to prior art, repeat no more.Leading flank refers to common in working order, and trailing flank is then for seldom to meet.
Principle of work of the present utility model and process
After coil spring 17 to be detected captures by the air-actuated jaw 15 in Material moving device, under the movement of relevant slide unit, make rotating shaft insert the central authorities of coil spring, 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 has withdrawn from the fixing of coil spring.
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.
