Abstract
The invention proposes a spring stretching and bending life testing apparatus for testing the bending life of a spring. The testing apparatus is composed of a base and a support fixed on the base; the support is provided with an arc-shaped disc and a transverse bar which are sequentially distributed along a longitudinal direction; the transverse bar is provided with a first fixing portion; the first fixing portion is located at the central axis of the arc-shaped disc; an arc-shaped through groove is formed in the arc-shaped disc; a mobile mechanism which can move along the through groove is installed in the arc-shaped through groove; the mobile mechanism is provided with a second fixing portion; the base is fixedly provided with a motor and a tensioning rack; two ends of the tensioning rack are provided with tensioning wheels; and the motor shaft of the motor, the tensioning wheels and the mobile mechanism are connected with one another through a rope, so that the motor can drive the mobile mechanism to move along the arc-shaped through groove. In a test, the motor drives the mobile mechanism and the second fixing portion on the mobile mechanism to move along the arc-shaped through groove, so that the spring can be in a bent compressed state, a vertically stretched state and a bent compressed state recurrently, and therefore, testing on the stretching and bending life of the spring can be realized.
Description
Technical field
The invention belongs to spring technical field of measurement and test, be related specifically to a kind of spring elongation flex life proving installation.
Background technology
Current spring test is all the compression and tension concentrating on spring, but in practical service environment, may occur utilizing the flexible situation of spring bending, such as say the support member utilizing spring as a vibrating device, and this vibrating device not only has the vibration of vertical direction, also has the vibration of horizontal direction, iff elastic force and the life-span of test spring vertical direction, ignore the spring bending life-span, just may cause the premature failure of vibrating device.Therefore be necessary to test the spring bending life-span.
Summary of the invention
The object of the invention is to propose a kind of spring elongation flex life proving installation, for test spring flex life.
Spring elongation flex life proving installation of the present invention is by base and be fixed on to be configured on base, described support is disposed with arc video disc and cross bar along the vertical direction, described cross bar is provided with the first fixed part, and described first fixed position is on the central axis of arc video disc; Described arc video disc is provided with arc-shaped slot, and described arc-shaped slot is provided with one can along the travel mechanism of groove movement, and described travel mechanism is provided with the second fixed part; Described base is installed with a motor and a tensioning frame, and the two ends of described tensioning frame are equipped with stretching pulley, and the motor shaft of described motor, stretching pulley and travel mechanism are connected by rope, thus make motor can drive travel mechanism arcuately groove move.
When testing, the two ends of spring being utilized respectively the first fixed part, the second fixed part fix, and then starter motor, thus drive travel mechanism and on the second fixed part arcuately groove move.Movement locus due to the second fixed part is arc, and therefore in the process of the second fixed part movement, spring will---the bending compressive state circulation of stretched vertically state-----, achieves the test in stretch bending life-span with bending compressive state.
Further, described travel mechanism is made up of with the roller being positioned at main body two ends the main body through groove, and arc video disc is sandwiched in wherein by the roller at described main body two ends.Roller not only can prevent travel mechanism from coming off from video disc, can also reduce the resistance of motion between travel mechanism and groove.
Further, the distance between described arc video disc and cross bar is adjustable, to adapt to the test of differing heights spring, in addition, by regulating the distance between arc video disc and cross bar, spring can also be made to be in compression or extended state, test more comprehensive.
Further, described first fixed part, the second fixed part are hook formation.As long as the first fixed part, the second fixed part are hooked spring end and can realize fixing, very convenient.
Spring elongation flex life proving installation of the present invention can be tested for the stretch bending life-span of spring, supplements the deficiency of conventional springs test, has good practicality.

Embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect and principle of work etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in Figure 1, the spring elongation flex life proving installation of the present embodiment is made up of base 1 and the support 2 be fixed on base 1, described support 2 is disposed with arc video disc 3 and cross bar 4 along the vertical direction, described cross bar 4 is provided with the first fixed part 5, and described first fixed part 5 is positioned on the central axis of arc video disc 3; Described arc video disc 3 is provided with arc-shaped slot, described arc-shaped slot is provided with one can along the travel mechanism of groove movement, this travel mechanism is made up of with the roller 8 being positioned at main body 7 two ends the main body 7 through groove, arc video disc 3 is sandwiched in wherein by the roller 8 at described main body 7 two ends, and the main body 7 of travel mechanism is provided with the second fixed part 9; Described base 1 is installed with a motor 10 and a tensioning frame 11, the two ends of described tensioning frame 11 are equipped with stretching pulley 12, motor 10 axle of described motor 10, stretching pulley 12 and travel mechanism are connected by rope 6, thus make motor 10 can drive travel mechanism arcuately groove move.
The roller 8 of clamping video disc 3 not only can prevent travel mechanism from coming off from video disc 3, can also reduce the resistance of motion between travel mechanism and groove.
Distance between arc video disc 3 and cross bar 4 is adjustable, to adapt to the test of differing heights spring, in addition, by regulating the distance between arc video disc 3 and cross bar 4, spring can also be made to be in compression or extended state, test more comprehensive.
Further, described first fixed part 5, second fixed part 9 is hook formation.As long as the first fixed part 5, second fixed part 9 is hooked spring end can realize fixing, very convenient.
When testing, utilized at the two ends of spring the first fixed part 5, second fixed part 9 to fix respectively, and then starter motor 10, motor 10 reciprocating rotation can by rope 6 drive travel mechanism and on the second fixed part 9 arcuately groove move back and forth.Because the movement locus of the second fixed part 9 is arcs, therefore in the process of the second fixed part 9 movement, spring will---the bending compressive state circulation of stretched vertically state-----, achieves the test in stretch bending life-span with bending compressive state.
