Abstract
The utility model provides a spring bending life -span testing arrangement to be used for the testing spring flex life. The utility model discloses a spring bending life -span testing arrangement by the base and the support on being fixed in the base constitute, the support is equipped with the horizontal pole, fixed mounting has a motor on the horizontal pole, the motor shaft of motor is towards the base direction, and the end fixing of motor shaft has a carousel, the bottom surface of carousel is equipped with off -centre in the first fixed part of motor shaft, the base is equipped with the second fixed part, the second fixed part is located motor shaft place straight line. In when test, utilize first fixed part, second fixed part respectively with the both ends of spring, and then the starter motor to the drive carousel rotates. Since first fixed part off -centre in motor shaft, so when the carousel rotated, the motor shaft rotation was wound to the upper end that will drive the spring, and the second fixed part lies in motor shaft place straight line, the spring will become the case of bending rotation like this, has realized the test of flex life.
Description
Technical field
The invention belongs to spring technical field of measurement and test, be related specifically to a kind of spring bending endurance testing device.
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 bending endurance testing device, for test spring flex life.
Spring bending endurance testing device of the present invention is by base and be fixed on to be configured on base, described support is provided with cross bar, described cross bar is installed with a motor, the motor shaft of described motor is towards base direction, the end winding support of motor shaft has a rotating disk, the bottom surface of described rotating disk is provided with the first fixed part being eccentric in motor shaft, and described base is provided with the second fixed part, and described second fixed position is on the straight line of motor shaft place.
When testing, the two ends of spring being utilized respectively the first fixed part, the second fixed part fixes, and then starter motor, thus drive dial rotation.Because the first fixed part is eccentric in motor shaft, therefore when dial rotation, the upper end of spring will be driven to rotate around motor shaft, and the second fixed position is on the straight line of motor shaft place, such spring will become case of bending to rotate, and achieves the test of flex life.
Further, described rotating disk is provided with a groove extended along rotating disk radial direction, and the top of described first fixed part is provided with stud, and described stud is through groove, and stud is respectively provided with a nut in the upper and lower both sides of rotating disk, described stud utilizes described nut to be fixed on rotating disk.By the adjustment position of stud on rotating disk groove, namely adjust the distance of stud and center of turntable (motor shaft position), thus the angle of bend of adjustment spring.
Described support is Height Adjustable column structure further, to adapt to the test of differing heights spring, in addition, by regulating the height of support, spring can also be made to be in compression or extended state, test more comprehensive.
Specifically, described first fixed part, the second fixed part are column structure, as long as the first fixed part, the second fixed part are snapped in spring end and can realize fixing, very convenient.
Spring bending endurance testing device of the present invention can be tested for the flex life of spring, supplements the deficiency of conventional springs test, has good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of spring bending endurance testing device of the present invention.
Accompanying drawing indicates: 1, base; 2, support; 3, motor; 4, rotating disk; 5, groove; 6, the first fixed part; 7, stud; 8, nut; 9, the second fixed part.
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 bending endurance testing device of the present embodiment is made up of rectangular base 1 and Height Adjustable " Г " shape support 2 be fixed on base 1, described support 2 is provided with cross bar, described cross bar is installed with a motor 3, the motor shaft of described motor 3 is towards base 1 direction, the end winding support of motor shaft has a rotating disk 4, and motor shaft is positioned at the center of rotating disk 4.
Rotating disk 4 is provided with a groove 5 extended along rotating disk 4 radial direction, namely one end of this groove 5 is towards motor shaft, the other end is toward rotating disk 4 edge, groove 5 is provided with the first fixed part 6, the top of the first fixed part 6 is provided with stud 7, described stud 7 is through groove 5, and stud 7 is respectively provided with a nut 8 in the upper and lower both sides of rotating disk 4, and described stud 7 utilizes described nut 8 to be fixed on rotating disk 4.
Described base 1 is provided with the second fixed part 9, and described second fixed part 9 is positioned on the straight line of motor shaft place.
When testing, the two ends of spring are utilized respectively the first fixed part 6, second fixed part 9, and then starter motor 3, thus drive rotating disk 4 to rotate.Because the first fixed part 6 is eccentric in motor shaft, therefore, when rotating disk 4 rotates, the upper end of spring will be driven to rotate around motor shaft, and the second fixed part 9 is positioned on the straight line of motor shaft place, such spring will become case of bending to rotate, and achieves the test of flex life.
By the adjustment position of stud 7 on the groove 5 of rotating disk 4, namely adjust the distance at stud 7 and rotating disk 4 center (motor shaft position), thus the angle of bend of adjustment spring.
Because support 2 is Height Adjustable, therefore can adapt to the test of differing heights spring, in addition, by regulating the height of support 2, spring can also be made always to be in compression or extended state, test more comprehensive.
