Specific Embodiment

[0025] The following further details the present utility model in conjunction with the specific embodiment and with reference to the drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present utility model.

[0026] Referring to the following drawings, non-limiting and non-exclusive embodiments will be described, where the same reference numerals represent the same components, unless otherwise specifically stated.

[0027] An automotive parts tensile testing equipment, as Figures 1 to 3As shown in the figure, it includes a base 1. Above the base 1, two lifting columns 2 are fixedly arranged. Between the two lifting columns 2, a first cross beam 3 and a second cross beam 4 are arranged up and down. The first cross beam 3 can also be directly arranged at the tops of the two lifting columns 2. When conducting a tensile test, the first cross beam 3 remains stationary, and the second cross beam 4 moves downward. The first fixed clamp 5 is connected to the lower part of the first cross beam 3, and the second fixed clamp 6 is connected to the upper part of the second cross beam 4. The mounting axes 15 of the first fixed clamp 5 and the second fixed clamp 6 are on the same axis. The first fixed clamp 5 and the second fixed clamp 6 cooperate to be able to clamp a long-strip product for tensile testing. On one side of the second fixed clamp 6, there is a mounting plate 7. A number of mounting holes are arranged on the mounting plate 7. The mounting plate 7 is arranged on a sliding mechanism, so that the mounting plate 7 can slide to or away from above the second fixed clamp 6. The mounting plate 7 provides a relatively wide mounting platform, and products with irregular shapes and inconvenient to be clamped by fixed clamps can be fixed on the mounting plate 7 for tensile testing, making the testing equipment multi-functional and having a wider application range. The sliding mechanism is mounted on a lifting mechanism. The lifting mechanism includes a connecting plate 8. The sliding mechanism is arranged on the connecting plate 8. A screw hole matching the second cross beam 4 is arranged on the side of the connecting plate 8, so that the connecting plate 8 can move up and down synchronously with the second cross beam 4. When it is necessary to use the mounting plate 7 to clamp and test a product, slide the mounting plate 7 to above the second fixed clamp 6; when it is necessary to clamp the test product with two fixed clamps, slide the mounting plate 7 out from above the second fixed clamp 6 and loosen the screw connecting the connecting plate 8 and the second cross beam.

[0028] The plastic welded parts produced by an auto parts factory usually have irregular shapes, and usually produce parts for different models of cars from different manufacturers at the same time. There are many types of parts that need to be tested for tensile strength. These parts are usually welded by two or more components. To test the strength of the welds and welded joints, tensile tests are usually required. It is not possible to simply clamp such parts up and down with two fixed clamps. The common method is to install the parts on the mounting plate 7. During the test, the second cross beam 4 drives the mounting plate 7 to move downward and cooperate with the first fixed clamp 5 above for tensile testing. Specifically, different clamping methods can be pre-adjusted and calibrated respectively, and then the adjusted data can be stored in the computer supporting the tensile testing equipment. When conducting subsequent tensile tests, only the corresponding fixture calibration data needs to be called to start the tensile test. This testing equipment provides multiple clamping methods, is multi-functional, can be applicable to the testing of various-shaped auto parts, has a wide application range, maximizes the value of the equipment, has a simple structure, is convenient to switch the fixtures, saves testing time, and improves testing efficiency.

[0029] Specifically, such as Figure 1The connecting plate 7 has a hollow structure, and an installation frame 9 is arranged on its upper part. The sliding mechanism is arranged on the installation frame 9 to reduce the weight of the connecting plate 8. A plurality of guide posts 10 are arranged on or around the connecting plate 8, and the connecting plate 8 can move up and down along the guide posts 10. A plurality of pressing blocks (not shown in the figure) are arranged on the mounting plate 7, and the pressing blocks are connected to the mounting plate 7 by screws and are used to clamp the automotive parts to the mounting plate 7. A plurality of irregularly arranged threaded holes can be arranged in advance on the mounting plate 7 to be suitable for the installation of various parts. After placing the parts to be tested on the mounting plate 7, press several points of the parts to be tested with the pressing blocks, and use screws to fix the pressing blocks on the mounting plate 7. Connect the parts to be tested with the testing equipment through ropes or other parts, and then the tensile test can be carried out. It can be understood that this testing equipment is equipped with a system for associated data transmission, processing, and display, which will not be introduced in detail here.

[0030] Specifically, as Figure 2 shown, the sliding mechanism includes a linear guide rail 11 and a slider (not shown in the figure). The mounting plate 7 is connected to the slider on the linear guide rail 11. Two sets of the sliding mechanisms can be arranged on the lifting mechanism, and the slider is connected to the middle part of the mounting plate 7 to make the sliding mounting plate smoother. In some other examples, two first mounting seats are arranged on the left and right sides of the second fixed clamp and on the second cross beam. The height of the first mounting seat is the same as the height of the connecting plate and is greater than the mounting height of the second fixed clamp. Mounting blocks are fixedly arranged on the first mounting seats, and mounting holes matching the mounting plate are arranged on the mounting blocks. When the mounting plate slides above the second fixed clamp, use screws to fix the mounting plate to the mounting blocks to make the overall structure more firm.

[0031] Specifically, as Figure 3 shown, the first mounting seat includes a first connecting plate 12, a second connecting plate 13, and a vertical plate 16. The vertical plate 16 is fixedly arranged between the first connecting plate 12 and the second connecting plate 13. The first connecting plate 12 is arranged above the vertical plate 16, and the mounting block (not shown in the figure) is fixedly arranged on the first connecting plate 12. The second connecting plate 13 is arranged below the vertical plate and is connected to the second cross beam 4. Specifically, a plurality of reinforcing plates 14 can be respectively arranged at the joints of the vertical plate with the first connecting plate 12 and the second connecting plate 13. The first mounting seat of this structure is light in weight, can effectively reduce the weight of the first mounting seat, reduce the load on the second cross beam 4, save material costs, and the reinforcing plates 14 make the structure of the first mounting seat more firm. In actual production activities, the mounting plate 7 is usually a wide and heavy metal plate. The parts to be tested can be fixed above the mounting plate first, and then the mounting plate is slid above the second fixed clamp for installation and testing.

[0032] Those skilled in the art will recognize that numerous modifications to the above description are possible, so the embodiments and the drawings are only used to describe one or more specific embodiments.

[0033] Although the exemplary embodiments that are regarded as the present utility model have been described and recited, those skilled in the art will understand that various changes and substitutions can be made thereto without departing from the spirit of the present utility model. Additionally, many modifications can be made to adapt a particular situation to the teachings of the present utility model without departing from the central concept of the present utility model described herein. Therefore, the present utility model is not limited to the specific embodiments disclosed herein, but the present utility model may also include all embodiments within the scope of the present utility model and their equivalents.
