Description

Technical Field

[0001] The present application relates to the technical field of fabric testing, and in particular to a seat lumbar net elasticity testing device. Background Art

[0002] On the seat production line, in order to maintain consistency in product quality, each batch of seat lumbar nets needs to be sampled and tested. At this time, the seat lumbar nets need to be quality tested using an elasticity testing device to measure the degree of deformation and recovery ability of the lumbar nets, thereby determining whether their elastic performance meets the design requirements.

[0003] For example, the patent with publication number CN109211671A specifically discloses a fabric elasticity testing device, which can fix the fabric through a clamping mechanism, so that the user does not need to stretch the fabric by hand, thereby preventing arm pain and improving the efficiency of fabric elasticity testing.

[0004] In the above patent, the device is provided with two sets of clamping mechanisms, so that when the device performs a tensile test on the fabric, it only needs to rotate the turntable to drive the two sets of jaws away from each other, thereby stretching the fabric and achieving the purpose of testing the elasticity. However, since the jaws in the device can only move upward in a single direction, it can only drive the fabric to be stretched in a single direction. When testing the mesh fabric, since the mesh fabric is woven from multiple sets of mesh wires, the effects of stretching in different directions on the fabric are also different when it is stretched. This unidirectional stretching is not sufficient to fully evaluate the elastic data of the fabric. Therefore, it is necessary to provide a seat lumbar net elasticity testing device to solve the above problems.

[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0030] like Figure 1-Figure 2 As shown, the present application provides a seat lumbar net elasticity testing device, comprising a testing mechanism 1, which is set in a seat processing plant and is used to evaluate the elastic performance of the seat lumbar net part;

[0031] The testing mechanism 1 includes a base 11, a first driving part 2 is provided on the top of the base 11, and the first driving part 2 includes two sets of first slide rails 21, and a first connecting plate 22 is slidably mounted on the first slide rails 21. At the same time, a first motor 23 is fixedly mounted on one side between the two sets of first slide rails 21, and a first screw 24 is fixedly mounted on the output end of the first motor 23. At the same time, a collar (not shown in the figure) is provided at the bottom of the first connecting plate 22, and a thread is provided inside the collar, and the thread is adapted to the thread on the surface of the first screw 24. The collar is threadedly mounted on the outside of the first screw 24, so that when the first motor 23 moves, it can drive the first connecting plate 22 to reciprocate on the first slide rail 21;

[0032] At the same time, two groups of columns 12 are provided on one side of the top of the base 11, and a second driving unit 3 is laterally provided on the side of the two groups of columns 12. The second driving unit 3 includes a second motor 31, and a second screw 32 is fixedly installed on the output end of the second motor 31. Second slide rails 33 are provided on both sides of the second screw 32. A second connecting plate 34 is slidably mounted on the second slide rail 33, and the second connecting plate 34 is threadedly connected to the second screw 32.

[0033] At the same time, a third driving part 4 is vertically arranged on the outer side of the second connecting plate 34, and the third driving part 4 includes a mounting plate 41. The bottom of the mounting plate 41 has two groups of sliders, and a slideway corresponding to the slider is provided on the outer side of the second connecting plate 34. At the same time, a third motor 42 is fixedly installed on the top of the mounting plate 41, and a third screw 43 is fixedly installed on the output end of the third motor 42. The third screw 43 is threadedly installed inside the second connecting plate 34, so that when the third motor 42 drives the third screw 43 to rotate, it will drive the mounting plate 41 to slide back and forth on the second connecting plate 34.

[0034] like Figure 2-Figure 4As shown, a first clamping portion 5 is provided at the bottom of the mounting plate 41. The first clamping portion 5 includes a mounting frame 51. The mounting frame 51 is adapted to be fixedly connected to the mounting plate 41 by bolts. An adjustment plate 52 is rotatably connected to the outer side of the mounting frame 51. A butterfly bolt 53 is provided at the connection between the adjustment plate 52 and the mounting frame 51. The butterfly bolt 53 is adapted to fix the adjustment plate 52 to the mounting frame 51.

[0035] At the bottom of the adjustment plate 52, two sets of clamping plates 54 are provided. The interiors of the clamping plates 54 are provided with multiple sets of uneven clamping grooves 55 suitable for contacting the seat lumbar mesh. Screws 56 are threadedly mounted on the outer sides of the two sets of clamping plates 54. The screws 56 are used to control the distance between the two sets of clamping plates 54 so as to clamp and secure the lumbar mesh to be tested. A second clamping portion 6 is provided on the top of the first connecting plate 22. The second clamping portion 6 has the same structure as the first clamping portion 5 and is used to clamp the other end of the lumbar mesh.

[0036] A pointer 521 is fixedly installed on the top of the adjustment plate 52, and the pointer 521 is suitable for moving synchronously with the rotation of the adjustment plate 52. At the same time, an indicator scale 511 is provided on the outer side of the mounting frame 51 at the position corresponding to the pointer 521. The pointer 521 is adapted to the indicator scale 511. Before the test, the staff can accurately control the rotation angle of the adjustment plate 52 (and the clamping plate 54) by observing the position of the pointer 521 on the indicator scale 511, so as to ensure that the waist net is uniformly stressed during the test. When it is necessary to test the stress conditions of the waist net at different angles, there is no need to replace the test equipment or reset the test environment. It is only necessary to adjust the rotation angle of the adjustment plate 52, which not only saves the operation time, but also reduces the repetitive work during the test.

[0037] When the elasticity of the seat lumbar mesh needs to be tested, a strain gauge (not shown) for testing is first fixedly installed at the center of the lumbar mesh. The strain gauge is electrically connected to an external signal receiving device and is suitable for transmitting lumbar mesh data to the outside. Then, the two ends of the lumbar mesh are clamped and fixed to the first clamping portion 5 and the second clamping portion 6, respectively. At this time, the lumbar mesh is in a flat state. Then, the first motor 23, the second motor 31, and the third motor 42 are controlled to move the first clamping portion 5 and the second clamping portion 6, respectively, so that the lumbar mesh is subjected to a predetermined force or displacement in the horizontal or vertical direction and is stretched until the lumbar mesh is stretched to its maximum length. Due to the forces and displacements from different directions, the lumbar mesh deforms. At the same time, the deformation amount, stress distribution and other parameters of the lumbar mesh are monitored in real time by the strain gauge, and the data is transmitted to a data recording system. Parameters such as the maximum deformation amount and deformation rate of the lumbar mesh during the force application process are analyzed, thereby reflecting the stiffness and strength of the lumbar mesh.

[0038] In summary, by setting up multiple sets of driving parts, the device can perform tensile tests on the waist net at different angles and directions, thereby improving the accuracy and reliability of the test and being able to more accurately evaluate the elastic performance of the waist net.

[0039] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
