Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spring detection equipment, in particular to a disc spring elasticity detection device. BACKGROUND

[0002] The material of the disc spring is spring steel, which is an important elastic element and is widely used in the fields of aerospace and automobile manufacturing. Its reliability and economy are crucial to the development of these fields. However, the elastic performance of the disc spring may decrease after long-term use or after experiencing multiple loads, directly affecting the performance and safety of the equipment.

[0003] At present, the disc spring is directly scrapped after use. However, the elasticity of some disc springs still meets the use requirements although they have been used, which causes waste of resources. In the existing disc spring detection methods, common methods include visual inspection and life assessment. Specifically, visual inspection mainly observes whether there are cracks, deformation and other obvious damages on the surface of the disc spring by naked eye; and life assessment is to estimate the remaining service life of the disc spring based on the use time and number of times.

[0004] However, although the above methods are simple and easy to implement, they have obvious deficiencies in actual application. For example, appearance inspection cannot accurately evaluate the influence of internal small defects of the disc spring on its elastic performance, and life assessment based on experience and time prediction may ignore the influence of different use environments on the aging speed of the disc spring. More importantly, due to the lack of accurate quantitative standards, these methods often lead to the misjudgment of qualified disc springs as needing to be scrapped, thereby causing material waste.

[0005] In the above related technology, there is a defect that the accuracy of disc spring elasticity detection is insufficient. CONTENT OF THE UTILITY MODEL

[0043] As shown in Figure 1 , Figure 2 and Figure 3 , the present application discloses a disc spring elastic detection device (hereinafter referred to as "device"). The device comprises a driving detection mechanism 1 and a supporting mechanism 2, which is used to detect whether the elasticity of one or more disc springs 100 meets the requirements.

[0044] As shown in Figure 2 , Figure 3 and Figure 4As shown, the driving detection mechanism 1 comprises a base 11, a driving assembly 12 and a detection assembly 13, the driving assembly 12 is arranged on the base 11, and the detection assembly 13 cooperates with the driving assembly 12. In the embodiment, the driving detection mechanism 1 can use an existing electronic tensile testing machine, the shell 121 provides a supporting action, the screw rod 122 is driven to rotate by the motor 125, the transmission plate 124 screwed on the screw rod 122 is vertically moved, and then the hydraulic cylinder 126 on the transmission plate 124 is vertically moved, and the downward pressing action on the disc spring 100 is realized by the vertical movement of the hydraulic cylinder 126. The guide rod 123 is also arranged in the shell 121, and the guide rod 123 is arranged on the transmission plate 124 to provide a guiding action. The electronic tensile testing machine has two hydraulic cylinders 126 with opposite moving directions, and the specific structure and principle of the electronic tensile testing machine are not described here; since the lower hydraulic cylinder 126 is used to realize the elastic detection function in the embodiment, which is different from the function of the original electronic tensile testing machine for stretching, only the structure and action principle related thereto are described. The detection assembly 13 can use the detection structure provided by the electronic tensile testing machine, and can measure the vertical moving distance of the hydraulic cylinder 126; and the electronic tensile testing machine also has a pressure detection piece 133, such as a pressure sensor, arranged on the base 11, so that the downward pressure can be measured, so that the elastic parameters of the disc spring 100 can be obtained through the relationship between the moving distance and the downward pressure, the principle and structure of the detection assembly 13 are similar to the use of the electronic tensile testing machine, and are not described in detail here. In the embodiment, the detection assembly 13 comprises a support table 131 and a computer 132 arranged on the support table 131, the support table 131 is arranged on one side of the driving assembly 12, the computer 132 integrates the required detection functions, the computer 132 is electrically connected with the pressure detection piece 133, can display related data, and obtains the size of the elastic force.

[0045] As Figure 2 , Figure 3 and Figure 4As shown, the support mechanism 2 comprises a support frame and a support cylinder 22, the support frame is arranged on the base 11 and on the pressure detection member 133, and is used for placing the disc spring 100, so that the pressure borne by the support frame can be transmitted to the pressure detection member 133. The lower end of the support cylinder 22 abuts against the upper end of the disc spring 100, and the axis of the support cylinder 22 is vertically arranged. The support frame is used for placing the disc spring 100, and the lower end of the support cylinder 22 abuts against the upper end of the disc spring 100, so as to ensure the stability of the disc spring 100 during the test. The driving assembly 12 can be vertically moved, and is used for pressing downward the upper end of the support cylinder 22, so as to exert a downward pressure on the disc spring 100 and transmit the pressure to the pressure detection member 133. The detection assembly 13 is used for measuring the downward pressure of the driving assembly 12 and the vertical moving distance of the driving assembly 12, so as to detect the elasticity of the disc spring 100. The vertical movement of the driving assembly 12 exerts a pressure on the upper end of the support cylinder 22, and the detection assembly 13 measures the pressure value and the vertical displacement in real time, so as to determine whether the elasticity of the disc spring 100 meets the use requirement. The disc spring 100 elasticity detection device can accurately measure the downward pressure and the vertical moving distance of the disc spring 100 during the pressure process, so as to accurately evaluate the elastic performance of the disc spring 100 and avoid resource waste.

[0046] As shown in Figure 2 , Figure 3 and Figure 5 , the lower side of the lower hydraulic cylinder 126 is provided with a bump stop, and the support mechanism 2 is correspondingly arranged below the bump stop. In use, a standard pressure value is set in advance, the bump stop is pressed downward to compress the disc spring 100 by driving the bump stop to move downward through the hydraulic cylinder 126. Under the rated pressure value, the compression amount of the disc spring 100 is measured. If the elasticity of the disc spring 100 is not good, the compression amount will be too large under the certain pressure value. The vertical moving distance and the downward pressure of the hydraulic cylinder 126 can form an elasticity curve, that is, the slope of the generated curve is compared with the slope of the preset qualified elasticity curve, so as to determine whether the elasticity meets the standard. The computer 132 is used for displaying the elasticity curve, and the standard pressure value of the disc spring 100 is the preset curve. As long as the preset curve requirement is met, it is indicated that the disc spring 100 can continue to be used or the new disc spring 100 meets the standard.

[0047] Optionally, the support frame comprises a bearing seat 211 and a support column 212. The lower end of the support column 212 is connected to the bearing seat 211, and the support column 212 extends vertically. The disc spring 100 is sleeved on the outer periphery of the support column 212, so that the disc spring 100 can be stably placed on the support column 212, and the disc spring 100 is prevented from deviating during the detection process, thereby improving the accuracy and reliability of the elasticity detection of the disc spring 100.

[0048] As shown in Figure 3 , Figure 6 and Figure 7As shown, optionally, the diameter of the support column 212 is less than or equal to the inner diameter of the disc spring 100, and the outer diameter of the bearing seat 211 is greater than or equal to the outer diameter of the disc spring 100, so that the support column 212 can provide stable support to the disc spring 100 without interfering with the disc spring 100, and the design of the support column 212 ensures that the disc spring 100 will not be laterally offset during detection, thereby improving the accuracy and reliability of the elastic detection of the disc spring 100. The support cylinder 22 is hollow, the inner diameter of the support cylinder 22 is greater than the diameter of the support column 212, and the outer diameter of the support cylinder 22 is greater than or equal to the outer diameter of the disc spring 100. The hollow design of the support cylinder 22 and the larger inner diameter than the diameter of the support column 212 enable the disc spring 100 to be stably sleeved on the outer periphery of the support column 212, and the outer diameter of the support cylinder 22 is greater than or equal to the outer diameter of the disc spring 100, so that the disc spring 100 can be uniformly pressed during detection, thereby improving the detection accuracy.

[0049] Optionally, the vertical length of the support cylinder 22 is greater than the vertical length of the support column 212, so that the upper end of the support cylinder 22 is higher than the upper end of the support column 212, thereby enabling the support cylinder 22 to apply pressure to the disc spring 100 under the action of the driving assembly 12, thereby more accurately detecting the elasticity of the disc spring 100 and ensuring the reliability of the detection result.

[0050] As shown in Figure 3 , Figure 4 and Figure 7 Optionally, the base 11 is provided with a limiting mechanism 4, the limiting mechanism 4 includes a fixed block 41, a plurality of limiting plates 42 and a plurality of extension pieces, and the limiting plates 42 and the extension pieces are one-to-one correspondingly arranged.

The extension pieces drive the limiting plates 42 to move horizontally, and the side of the limiting plate 42 away from the extension piece is used to abut against the inner side wall of the base 11, thereby effectively limiting the horizontal movement of the base 11.

[0051] Optionally, the telescopic part comprises a first screw rod 431, a second screw rod 432 and a sleeve part 433 provided with internal threads. The first end of the first screw rod 431 is connected to the limiting plate 42, and the second end of the first screw rod 431 is screwed to the first end of the sleeve part 433. The first end of the second screw rod 432 is connected to the fixed block 41, and the second end of the second screw rod 432 is screwed to the second end of the sleeve part 433. The rotation of the sleeve part 433 can drive the first screw rod 431 and the second screw rod 432 to move in opposite directions, so as to accurately adjust the position of the limiting plate 42 and realize the stable limiting of the base 11. Specifically, the screw threads of the first screw rod 431 and the second screw rod 432 can be made to rotate in opposite directions, and the internal threads at both ends of the sleeve part 433 can be made to cooperate with the screw threads of the first screw rod 431 and the second screw rod 432 respectively, so that when the sleeve part 433 rotates, the first screw rod 431 and the second screw rod 432 can realize synchronous horizontal movement out of or into the sleeve part 433.

The side of the limiting plate 42 away from the telescopic part is provided with a second inclined part, and the first inclined part 112 cooperates with the second inclined part. The cooperation of the first inclined part 112 and the second inclined part makes the limiting plate 42 better limit the horizontal movement of the base 11 when it is attached to the inner side wall of the base 11, thereby improving the overall stability of the detection device. At the same time, the first inclined part 112 and the second inclined part can provide a guiding effect, which facilitates the installation of the base 11.

[0053] As shown in Figure 2 and Figure 3 , optionally, the device further comprises a climbing ladder 3. The climbing ladder 3 is movable, and the height of the climbing ladder 3 is greater than half the height of the base 11.
