[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Examples, such as Figures 1-7As shown, a step-in horizontal V-shaped bidirectional balanced tensile testing machine includes a test platform 1, used to ensure the stability of the equipment and ensure the effective conduct of the test. The tensile testing machine body is mounted above the test platform 1. The tensile testing machine body includes a structural frame 2, which includes longitudinally arranged longitudinal frames 21. Each longitudinal frame 21 includes a support frame 211. Two sets of parallel I-beams 212 are arranged above the support frame 211. The I-beams 212 facilitate the smooth movement of the first machine base 3 or the second machine base 4 to meet different testing requirements. Between the two longitudinal frames 21... A tailstock 23 is provided, which provides a prerequisite for the stable setting of the main unit base 5. A transverse frame 22 is provided on one side of the tailstock 23. The transverse frame 22 includes a U-shaped frame 221, which is the main component of the transverse frame 22. Guide rails 222 are provided on both sides of the U-shaped frame 221 to facilitate the smooth movement of the main unit base 5. Multiple support rods 223 are evenly distributed inside the U-shaped frame 221, which provides a prerequisite for the locking of the main unit base 5 and reduces the possibility of its displacement. The first base 3 and the second base 4 are respectively provided on the front and rear longitudinal frames 21. The main body 5 is provided on the 2nd base. The output ends of the first base 3 and the second base 4 are respectively provided with a first connecting rope 6 and a second connecting rope 7. The output end of the main body 5 is provided with a third connecting rope 8. A sample 9 is placed between the ends of the first connecting rope 6 and the second connecting rope 7 and the end of the third connecting rope 8. Specifically, when conducting a tensile test on the sample 9, if it is subjected to horizontal transverse tensile force, the first base 3 and the second base 4 are adjusted to be close to the tailstock 23. The position of the main body 5 is adjusted according to the length of the sample 9. After all positions are adjusted, the main cylinder in the main body 5 is controlled to operate, so as to achieve… The test involves two methods: one is to perform a horizontal tensile test on the specimen 9, and the other is to perform a horizontal lateral tensile test. This is achieved by adjusting the positions of the first base 3 and the second base 4, and then adjusting the position of the main base 5 according to the specifications of the specimen 9. Then, according to the test requirements, the auxiliary tension cylinder 35 on the first base 3 or the second base 4 is controlled to operate, thereby completing the lateral tensile test on the specimen 9. The cooperation between the three methods can complete tensile tests on the specimen 9 in different directions, such as transverse tensile or lateral tensile, to provide different test data, making it easier to inspect the quality of the workpiece and meet the needs of the test work.

[0025] In the above process, by utilizing the established main base 5, first base 3, and second base 4, the tensile tests on the sample 9 in different directions, such as transverse tension or lateral tension, can be completed, providing different test data and facilitating the inspection of workpiece quality, thus meeting the needs of testing work. This device is reasonably designed, has a simple structure, is easy to process, and can realize tensile tests on the sample 9 in multiple directions, ensuring that the sample 9 completes diverse tests, enriching the test results, promoting the measurement of the quality of the sample 9, and meeting the needs of use.

[0026] To improve the rationality of the device setup and enhance the tensile treatment of sample 9 in multiple directions, it is necessary to further explain that: the first base 3 and the second base 4 have the same structure, but the positions of their components are arranged in a mirror image. The first base 3 will be described in detail below: the first base 3 includes a movable frame 31, within which a longitudinal transfer wheel 32 is installed, spanning across the frame to ensure smooth movement. A positioning mechanism 10 is provided on one side of the movable frame 31 to position the first base 3 and reduce the possibility of displacement. An L-shaped limiting plate 33 is provided on the outer side of the movable frame 31 and engages with the I-beam 212. A mounting base 34 is provided above the movable frame 31, and a rotatable and adjustable auxiliary tension cylinder 35 is provided at the lower end of one side of the mounting base 34. The auxiliary tension cylinder 35 can be rotated and adjusted horizontally relative to the mounting base 34 to meet the requirements of the device for tensile testing in different directions, improving the functionality of the device and accelerating the work process.

[0027] To secure the first base 3 and reduce the possibility of displacement, thereby ensuring the effective conduct of the tensile test, the positioning mechanism 10 includes a wedge-shaped block 101 connected to the movable frame 31. A groove 1011 is formed on the inclined surface of the wedge-shaped block 101. A wedge-shaped locking block 102 is located below the wedge-shaped block 101. A slide bar 1021 is provided on the inclined surface above the locking block 102 and is adapted to the groove 1011. A double-acting gas valve is provided between the two locking blocks 102. Cylinder 103 is specifically described as follows: When the first base 3 is moved to a suitable position, the double-acting cylinder 103 is operated, which can drive the locking block 102 to slide relative to the wedge block 101 until one end face of the locking block 102 abuts against the inner side of the limiting plate 33. The inner side of the short side of the limiting plate 33 abuts against the inner side of the I-beam 212, and the locking block 102 and the wedge block 101 cooperate and fit tightly together. In this way, the positioning and fastening of the first base 3 is achieved, preventing it from shifting and ensuring the effective implementation of the stretching work.

[0028] To achieve the main tensile test in the lateral direction, the main unit base 5 includes a base 51. A transverse guide wheel 52 is provided on the outer side of the base 51 and is adapted to the guide rail 222. When the position of the main unit base 5 is adjusted, the transverse guide wheel 52 can slide relative to the guide rail 222 to ensure smooth operation. A mounting frame 53 is provided above the base 51, and a rotatable adjustable main tension cylinder 54 is provided below the mounting frame 53. The main tension cylinder 54 can be rotated and adjusted in the horizontal direction to adapt to tensile tests at different angles. The base 51 also includes... A power drive assembly is provided to control the movement and adjustment of the main host base 5 relative to the transverse frame 22, and acts on the transverse transfer wheel 52 to enable adaptive adjustment. An auxiliary locking mechanism 11 is provided below the base 51 near the output end of the main tension cylinder 54. On the other side of the base 51 opposite to the auxiliary locking mechanism 11, a main locking mechanism 12 is provided. The cooperation between the auxiliary locking mechanism 11 and the main locking mechanism 12 can realize the positioning and locking of the main host base 5, reduce the possibility of its displacement, ensure stability, and meet the usage requirements.

[0029] To lock the position of the main unit 5, the auxiliary locking mechanism 11 includes a first locking cylinder 111, the mounting end of which is hinged to the inside of the base 51. A lug 112 is provided on one side of the base 51, and a locking plate 113 with an obtuse angle is provided inside the lug 112. The upper end of the locking plate 113 is connected to the output end of the first locking cylinder 111, and an arc groove 1131 is provided in the lower end of the locking plate 113. Specifically, after the main unit 5 is moved to a suitable position, the first locking cylinder 111 is controlled to run, causing the lower part of the locking plate 113 to rotate relative to the lug 112, and the arc groove 1131 of the locking plate 113 rests on the support rod 223. By using the locking plate 113 to act on the support rod 223 in a top manner, the possibility of the main unit 5 swaying in the lateral direction is reduced, and the stability is improved.

[0030] To effectively position the main unit 5, the main locking mechanism 12 includes a J-shaped locking rod 121. A second locking cylinder 122 is located on the rear side of the base 51, and its output end is hinged to the upper part of the locking rod 121. Specifically, after the main unit 5 is moved to a suitable position, the second locking cylinder 122 is controlled to rotate, causing the locking rod 121 to rotate. The inner arc of the locking rod 121 then engages with the support rod 223, thus preventing the main unit 5 from moving laterally towards the longitudinal frame 21. In conjunction with the auxiliary locking mechanism 11, this fully ensures the stability of the main unit 5's position and fully meets the usage requirements.
