[0039] Please refer to Figures 1 to 4 。

[0040] In the specific embodiment, the test positioning and supporting device provided by the present utility model includes a horizontal cross support plate 11 extending in the horizontal direction and a vertical longitudinal support plate 12 extending in the vertical direction. The longitudinal support plate 12 is vertically disposed on the top of the cross support plate 11.

[0041] On this basis, a transfer assembly 13 capable of supporting the product to be tested 20 is detachably disposed on at least one of the cross support plate 11 and the longitudinal support plate 12.

[0042] During the assembly and operation process, for the impact test requirements of the product, the product to be tested can be reliably assembled on the cross support plate 11 or the longitudinal support plate 12 through the transfer assembly 13 according to different test needs. Thus, by utilizing the coordinated cooperation of the horizontally arranged cross support plate 11 and the vertically arranged longitudinal support plate 12 and their respective assembly arrangements with the product to be tested 20, the vibration and impact tests in the X direction, Y direction, and Z direction of the product to be tested 20 can be realized, so as to match the vibration and impact operations of the impact test equipment in different directions, meet the requirements of the vibration and impact tolerance tests of the product to be tested 20 in multiple directions, and thus greatly improve the vibration and impact test effect of the product to be tested 20. After a single test is completed, it is only necessary to use the transfer assembly 13 to unload the product that has completed the test from the cross support plate 11 or the longitudinal support plate 12 and replace it with the next product to be tested, and then the batch continuous test process of multiple products to be tested 20 can be realized, thereby significantly improving the corresponding product vibration and impact test efficiency and optimizing the working performance of the test positioning and supporting device.

[0043] During actual operation and application, it can be as Figure 3 shown, only one product to be tested 20 is correspondingly arranged on the longitudinal support plate 12 to perform the vibration and impact test in the X-axis direction on this product; it can also be as Figure 4As shown in the figure, a product 20 to be tested is correspondingly arranged on the longitudinal support plate 12, and at the same time, a product 20 to be tested is also correspondingly arranged on the transverse support plate 11. Thus, during a single vibration operation of the impact testing device, synchronous testing of two products 20 to be tested can be achieved, and the vibration impact testing in the Y direction and Z direction of the products can be correspondingly completed, thereby greatly improving the product throughput of a single testing operation and significantly improving the working efficiency of the impact testing device and its vibration impact testing efficiency for products.

[0044] It is not difficult to understand that the number of products 20 to be tested correspondingly arranged on the transverse support plate 11 and the longitudinal support plate 12, the installation direction of the products 20 to be tested on the corresponding transverse support plate 11 and longitudinal support plate 12, etc. mentioned above are all for illustrative purposes. In actual applications, the installation direction and the arrangement quantity of the products 20 to be tested on the transverse support plate 11 and the longitudinal support plate 12 can be flexibly selected and adjusted according to specific working conditions requirements and actual assembly space, and are not limited to the situations as Figure 3 and Figure 4 shown in the figure; correspondingly, the directions of vibration impact testing that can be achieved by the products after being installed in the corresponding positions can also be adjusted accordingly, and the staff can make flexible choices. In principle, as long as the vibration impact testing requirements of the products 20 to be tested can be met and the working needs of the test positioning and supporting device and the impact testing device can be ensured.

[0045] Specifically, a support strengthening component 14 is connected between the transverse support plate 11 and the longitudinal support plate 12. By using this support strengthening component 14, the connection structure between the transverse support plate 11 and the longitudinal support plate 12 can be reliably strengthened in strength, thereby further optimizing the assembly connection reliability between the transverse support plate 11 and the longitudinal support plate 12, enabling the vertically arranged longitudinal support plate 12 to obtain sufficient and reliable structural support, thus correspondingly improving the overall structural strength of the test positioning and supporting device, and making the positioning and support of the test positioning and supporting device for the products 20 to be tested more stable and reliable.

[0046] Furthermore, the support strengthening component 14 includes side support plates 141 that are arranged in a fitting manner on the side parts of the transverse support plate 11 and the longitudinal support plate 12, and also includes side support bolts 142 that are inserted horizontally and penetrate through the side support plates 141, and the side support bolts 142 can be threadedly connected to the transverse support plate 11 or the longitudinal support plate 12.

[0047] Generally, the outer walls on the same side of the transverse support plate 11 and the longitudinal support plate 12 are coplanar, so that the main structure of the test positioning and supporting device is more regular. On this basis, by arranging the side support plates 141 in a fitting manner at the connection of the outer side walls of the transverse support plate 11 and the longitudinal support plate 12, and then cooperating with the through assembly and threaded fastening of the side support bolts 142, the side support plates 141 can provide reliable auxiliary support for the side parts of the transverse support plate 11 and the longitudinal support plate 12, playing the role of a reinforcing rib.

[0048] It is not difficult to understand that side support threaded holes are respectively arranged on the side walls of the transverse support plate 11 and the side walls of the longitudinal support plate 12 for aligning and inserting the side support bolts 142 and threadedly connecting them, thereby ensuring the assembly accuracy and assembly strength of the side support bolts 142.

[0049] Furthermore, the bottom end of the longitudinal support plate 12 is connected to one end of the transverse support plate 11, the side support plate 141 is a right-angled triangle plate, and one of the right-angled sides of the side support plate 141 is parallel to and aligned with the side of the transverse support plate 11, and the other right-angled side of the side support plate 141 is parallel to and aligned with the side of the longitudinal support plate 12, and the side support bolt 142 is arranged through the right-angled side of the side support plate 141.

[0050] Arranging the longitudinal support plate 12 at one end of the transverse support plate 11 can make the assembly space between one side of the longitudinal support plate 12 and the top of the transverse support plate 11 available for arranging the tested product 20 more regular and sufficient to meet the product testing and installation requirements under normal working conditions.

[0051] On this basis, the side support plate 141 is designed as a right-angled triangle, and the two right-angled sides of the side support plate 141 can be used as matching parts for fitting with the transverse support plate 11 and the longitudinal support plate 12, thereby further improving the structural adaptability of the side support plate 141 and the transverse support plate 11 and the longitudinal support plate 12, and optimizing the assembly strength and supporting effect therebetween accordingly.

[0052] Of course, in actual applications, the longitudinal support plate 12 can also be arranged in the middle of the top surface of the transverse support plate 11, so that assembly space for arranging the tested product 20 is formed on both sides of the longitudinal support plate 12 to meet the layout, installation and testing requirements of the tested product 20 under different working conditions.

[0053] In addition, the side support plate 141 is an aluminum plate. Accordingly, the horizontal support plate 11 and the vertical support plate 12 can also be made of aluminum plates. The processing and forming difficulty of aluminum plates is low, which can effectively reduce the processing difficulty of each plate of the test positioning support device and reduce the corresponding device application cost. In addition, the structure of the aluminum plate is light and reliable, which can effectively reduce the dead weight of the test positioning support device, making its components easier to carry, organize, disassemble and arrange, thereby further reducing the operating difficulty of the test positioning support device and improving its ease of use.

[0054] On the other hand, the adapter assembly 13 includes an adapter plate 131 that can be fitted on the top surface of the transverse support plate 11 or the main extension surface of the longitudinal support plate 12, and also includes an adapter bolt 132 that can be inserted into and penetrate the adapter plate 131, and the adapter bolt 132 can be threadedly connected to the transverse support plate 11 or the longitudinal support plate 12.

[0055] During actual operation, the adapter plate 131 can provide sufficient and reliable planar structure support for the product under test 20, thereby ensuring stable and reliable stress conduction of the product during the vibration and shock test, avoiding uneven stress or local stress concentration of the product under test 20 during the vibration and shock test, preventing accidental damage to the product during the test, and ensuring accurate and reliable test results of the product.

[0056] On this basis, using the adapter bolt 132 as the fastening connecting piece between the adapter plate 131, the horizontal support plate 11 and the vertical support plate 12, the advantages of simple disassembly and assembly of the adapter bolt 132 can be utilized to make the disassembly and installation of the product under test 20 on the horizontal support plate 11 and the vertical support plate 12 more convenient and efficient, further reducing the operation difficulty of the test positioning and supporting device and improving its usability.

[0057] More specifically, a number of positioning screw holes 15 that can be thread-fitted with the adapter bolt 132 are respectively arranged in an array on the horizontal support plate 11 and the vertical support plate 12. The arrayed positioning screw holes 15 are thread-connected in alignment with the corresponding adapter bolts 132, which can effectively optimize the utilization rate of the installation space of the adapter plate 131 and make the layout structure of the product under test 20 located on the adapter plate 131 more regular, thereby making the positioning and supporting effect of the test positioning and supporting device on the product under test 20 better.

[0058] It should be particularly noted that in actual application, if there is a higher requirement for assembly strength, when the bolts mentioned in this solution are thread-connected with the adapted screw holes, thread glue can be applied to the thread mating surface to further improve the fastening strength between each bolt and the corresponding screw hole, avoiding loosening of the bolt and the screw hole due to overly strong vibration and shock during the operation of the impact test equipment.

[0059] Correspondingly, after each bolt and the corresponding screw hole are assembled in place, welding can also be performed at the inner thread gap to further improve the connection strength and assembly stability between each bolt and the screw hole.

[0060] In addition, a number of weight-reducing process holes 16 are provided on the horizontal support plate 11 and the vertical support plate 12. Each weight-reducing process hole 16 on the horizontal support plate 11 is arranged at intervals with each positioning screw hole 15 in the length direction and width direction of the horizontal support plate 11, and each weight-reducing process hole 16 on the vertical support plate 12 is arranged at intervals with each positioning screw hole 15 in the height direction and width direction of the vertical support plate 12.

[0061] The arrangement of each weight-reducing process hole 16 can further reduce the self-weight of the horizontal support plate 11 and the vertical support plate 12, making related operations such as handling, assembling, and arranging of the test positioning and supporting device more convenient and easy, and reducing the labor intensity of the corresponding staff.

[0062] Of course, the arrangement of the weight-reducing process holes 16 should be based on the basic requirement of ensuring that the structural strength of the horizontal support plate 11 and the vertical support plate 12 meets the operating conditions of the vibration and shock tests, so as not to have an adverse impact on the vibration and shock tests of the product.

[0063] On this basis, arranging the weight-reducing process holes 16 and the positioning screw holes 15 at intervals helps to further improve the utilization rate of the assembly space on the main extension surfaces of the horizontal support plate 11 and the vertical support plate 12, avoid structural interference between the weight-reducing process holes 16 and the relevant adapter connectors of the positioning screw holes 15, and enable the component layout on the horizontal support plate 11 and the vertical support plate 12 to be more regular, and the disassembly and assembly operations of the components to be more accurate and efficient, so that the operation and use of the test positioning and supporting device are more convenient and efficient.

[0064] In a specific embodiment, the impact test equipment provided by the present invention includes a horizontally arranged test bench 10, and a test positioning and supporting device is provided on the top of the test bench 10, and the test positioning and supporting device is the test positioning and supporting device as described above. The test positioning and supporting device of this impact test equipment can realize the vibration and shock tests of the product in multiple directions, thereby improving the impact test effect on the product.

[0065] In summary, the test positioning and supporting device provided in the present invention includes a horizontally extending horizontal support plate and a vertically extending vertical support plate, and the vertical support plate is vertically arranged on the top of the horizontal support plate; at least one of the horizontal support plate and the vertical support plate is detachably provided with an adapter component capable of supporting the product to be tested.

[0066] During its assembly, operation and use, for the impact test requirements of the product, the product to be tested can be reliably assembled on the horizontal support plate or the vertical support plate through the adapter component according to different test needs. Thus, by utilizing the coordinated cooperation of the horizontally arranged horizontal support plate and the vertically arranged vertical support plate and their respective assembly arrangements with the product to be tested, the vibration and shock tests of the product to be tested in the X direction, Y direction and Z direction can be realized respectively, so as to match the vibration and shock operations of the impact test equipment in different directions, meet the requirements of the vibration and shock tolerance tests of the product to be tested in multiple directions, and thus greatly improve the vibration and shock test effect of the product to be tested. After a single test is completed, only need to use the adapter component to unload the product that has completed the test from the horizontal support plate or the vertical support plate, and replace it with the next product to be tested, then the batch continuous test processing of multiple products to be tested can be realized, thereby significantly improving the corresponding product vibration and shock test efficiency and optimizing the working performance of the test positioning and supporting device.

[0067] The present invention also provides an impact test equipment, and its test positioning and supporting device can realize the vibration and shock tests of the product in multiple directions, thereby improving the impact test effect on the product.
