DETAILED DESCRIPTION
[0023] To facilitate understanding of the present invention, the present invention is described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided solely to provide a more thorough and comprehensive understanding of the present disclosure.
[0024] See attached Figure 1 、 5As shown, an XYZ axis coordinate system reference is established. In this embodiment, a multi-directional load test fixture for an automobile hinge includes a fixed seat 1, a guide rail 2, at least one, preferably two connecting sliders 3, a longitudinal tension module 5, a transverse tension module 4 and two screws 6 for connecting a tensile machine and a test fixture. The guide rail 2 is laid on the fixed seat 1, and the connecting slider 3 is slidably installed on the guide rail 2, wherein the longitudinal tension module 5 and the transverse tension module 4 are detachably installed on the connecting slider 3; the longitudinal tension module 5 or the transverse tension module 4 is provided with a traction mold structure connected to the hinge assembly 7 to be tested, wherein the tensile machine is respectively connected to the fixed seat 1 and the traction mold through the screw 6. Specifically, by connecting the fixed seat 1 to the tensile machine, it is possible to avoid the fixed seat 1 from being subjected to excessive force during the tensile test. Deformation or damage, reducing influencing factors, ensuring the accuracy of experimental conclusions; different from the suspended test fixtures that are connected to the tensile machine at both ends, which will shake during the tensile test, by connecting the hinge A71 to the fixed seat 1, and the hinge B72 to the longitudinal tensile module 5 or the transverse tensile module 4, under the tension of the tensile machine, the hinge B72 moves along the guide rail 2, thereby improving the stability of the tensile test; secondly, by adjusting the placement of the hinge assembly 7 in the longitudinal tensile module 5 or the transverse tensile module 4, the hinge assembly 7 is successively subjected to two tensile forces on the same axis and in opposite directions, thereby realizing a longitudinal tensile test or a transverse tensile test on the hinge assembly 7, and, by recording relevant data through the tensile machine, the data is transmitted to the back end for aggregation, so as to draw conclusions with higher accuracy.
[0025] It should be noted that in conventional integrated test fixtures, multiple loads are applied at the same location along the same axis and in opposite directions to determine the lateral or longitudinal stress conditions of the hinge assembly 7. Due to the large number of test items, the accuracy of the test conclusions obtained is relatively low. Furthermore, due to the multiple and different test directions, the connection and fixing structure is relatively complex, requiring high operator skills, resulting in high initial investment costs and low production efficiency. In contrast, in the multi-directional load test fixture of this embodiment, the longitudinal tension module 5 or the transverse tension module 4 can be installed on the connecting slider 3 according to the test type, thereby performing longitudinal or transverse tension tests accordingly, thereby improving the accuracy of the test conclusions. Furthermore, the module installation structure is simple, and installation and removal can be performed sequentially at the same location, requiring low operator skills and low initial investment costs. Furthermore, the longitudinal or transverse tension tests of the hinge assembly 7 performed using the longitudinal tension module 5 and the transverse tension module 4 comply with the strength test standard for vehicle door hinges specified in GB / T 15086. Furthermore, the tensile testing machine used in this embodiment can be purchased from outside and is not specifically limited here.
[0026] See attached Figure 8As shown, further, the hinge assembly 7 includes a pair of mutually hinged hinges A71 and hinge B72 and a connecting pin 73. The hinge A71 is provided with a first-level hinge hole 711 and a first-level fixing hole 712, and the hinge B72 is provided with a second-level hinge hole 721 and a second-level fixing hole 722. The first-level fixing hole 712 is used to cooperate with a preset bolt to fix the hinge A71 to the longitudinal tension module 5 or the transverse tension module 4, and the second-level fixing hole 722 is used to cooperate with a preset bolt to fix the hinge B72 to the longitudinal tension module 5 or the transverse tension module 4. After the connecting pin 73 passes through the first-level hinge hole 711 and the second-level hinge hole 721, the hinge A71 and the hinge B72 are hinged to each other. Secondly, the hinge assembly 7 also includes some bushings, gaskets and other components, which are not specifically limited here.
[0027] See attached Figure 2 As shown, further, the fixing seat 1 is composed of a fixing mold 11 and a fixing block 12, and the fixing seat 1 is an L-shaped structure. Corresponding screw holes are provided on the fixing mold 11 and the fixing block 12, and are connected by preset bolts. When performing longitudinal or transverse tensile tests, the holes formed on the fixing mold 11 are different and need to be replaced. The split design makes it easier for the fixing mold 11 to adapt to the fixing methods of different tensile modules, so that the replaced fixing mold 11 can achieve a stable connection with the hinge A71 and the tensile machine.
[0028] See attached Figure 1-4 As shown, in the first embodiment, when the hinge assembly 7 is subjected to a lateral tensile test, the lateral tensile module 4 includes a lateral traction mold 41, a steering member 42 and a primary connecting plate 43. The lateral traction mold 41 is used to cooperate with the fixed mold 11 to perform a lateral tensile load test on the hinge assembly 7. The steering member 42 is used to connect the hinge A71 and the fixed mold 11, and a positioning hole is formed on one side end of the steering member 42 and is arranged along the Y-axis direction. When the lateral tensile test is performed, the placement posture of the hinge assembly 7 is as follows: Figure 4 As shown, the axial directions of the primary fixing hole 712 on the hinge A71 and the primary connecting hole 111 on the fixed mold 11 are perpendicular to each other, which makes it inconvenient to fix the hinge A71. In order to ensure that the hinge A71 is relatively fixed, the hinge A71 is connected to the fixed mold 11 through the steering member 42, thereby achieving the purpose of making the hinge A71 relatively fixed, so as to improve the stability of the subsequent lateral tensile test and improve the accuracy of the test conclusion.
[0029] Furthermore, an inclined setting is formed on one end surface of the transverse traction mold 41, and a first-level screw hole 411 is formed on the inclined position. The hinge B72 is fixed to the inclined position of the transverse traction mold 41 by a preset bolt. A first-level screw hole 412 for installing the screw 6 is formed on the other end surface of the transverse traction mold 41. At least one, preferably two, first-level connecting holes 111 that pass through and are arranged along the Y-axis direction and a second-level screw hole 112 for installing the screw 6 are formed on one side end of the fixed mold 11, wherein the first-level connecting hole 111 and the first-level screw hole 412 are located on the same X-axis and Y-axis positions, the first-level screw hole 412 and the second-level screw hole 112 are arranged on the same axis, and the first-level connecting hole 111 is used to match The steering member 42 is installed on the fixed mold 11 with the pre-existing bolts. By locating the first-level connecting hole 111 and the first-level screw hole 412 on the same X-axis and Y-axis position, the overall force of the hinge assembly 7 can be on the same axis as the tension of the tensile machine; secondly, by arranging the first-level screw hole 412 and the second-level screw hole 112 on the same axis, the hinge assembly 7 can be subjected to lateral tension on the same axis and in opposite directions, which is more convenient to improve the accuracy of the test conclusion. In addition, the inclined setting of the above-mentioned lateral traction mold 41 is used to cooperate with the placement posture of the hinge assembly 7, so that the hinge assembly 7 is switched to a state of bearing lateral tension, thereby realizing the lateral tension test of the hinge assembly 7, reducing the difficulty of operation and improving production efficiency.
[0030] In this embodiment 2, there are several aspects different from the embodiment 1: Figure 5-7As shown, when the hinge assembly 7 is subjected to a longitudinal tensile test, the longitudinal tensile module 5 includes a longitudinal traction mold 51 and a secondary connecting plate 52. The longitudinal traction mold 51 is used to cooperate with the fixed mold 11 to perform a longitudinal tensile load test on the hinge assembly 7. An inclined setting is formed on one end surface of the longitudinal traction mold 51, and a secondary screw hole 511 is formed on the inclined position. The hinge B72 is fixed to the inclined position of the longitudinal traction mold 51 by a preset bolt. A tertiary screw hole 512 for installing the screw 6 is formed on the other end surface of the longitudinal traction mold 51. A secondary connecting hole 113 and a fourth screw hole 114 for installing the screw 6 are formed on one side end of the fixed mold 11, wherein the secondary connecting hole 113 and the fourth screw hole 114 are located on the same X-axis. In the Y-axis position, the tertiary screw hole 512 and the fourth screw hole 114 are arranged on the same axis; the secondary connecting hole 113 is used to cooperate with the preset bolts to install the hinge A71 to the fixed mold 11. Similarly, by arranging the secondary connecting hole 113 and the fourth screw hole 114 on the same X-axis and Y-axis positions, the overall force of the hinge assembly 7 can be on the same axis as the tension of the tensile machine; secondly, by arranging the tertiary screw hole 512 and the fourth screw hole 114 on the same axis, the hinge assembly 7 can be subjected to longitudinal tension on the same axis and in opposite directions, which is more convenient for improving the accuracy of the test conclusion. In addition, the tilt setting of the above-mentioned longitudinal traction mold 51 is used to cooperate with the placement posture of the hinge assembly 7, so that the hinge assembly 7 is switched to a state of bearing longitudinal tension, see Appendix. Figure 7 As shown, the longitudinal tensile test of the hinge assembly 7 is achieved, the operation difficulty is reduced, and the production efficiency is improved.
[0031] It should be noted that by arranging a guide rail 2 and a sliding connecting slider 3 in the above-mentioned longitudinal tension module 5 and transverse tension module 4, the hinge A71 and the hinge B72 can be subjected to vertical force along the Z direction, thereby preventing the hinge A71 and the hinge B72 from sliding out along the axial direction (X-axis direction) of the connecting pin 73 when conducting longitudinal or transverse tensile load tests, thereby ensuring the effective and stable implementation of the tensile load test.
