Technical Field

[0001] This utility model relates to the field of testing machine technology, specifically to a rapid calibration sample clamp device for a testing machine. Background Technology

[0002] A testing machine is a precision testing instrument used to determine the mechanical properties, technological properties, internal defects, and dynamic imbalance of rotating parts of materials, components, or engineering structures under various conditions. It is widely used in the fields of metallic materials, non-metallic materials, mechanical parts, and engineering structures, and is an important tool for researching new materials, technologies, and processes. Testing machines can perform various mechanical property tests on materials, including tensile, compression, bending, shear, torsion, fatigue, and impact tests, to evaluate their strength, rigidity, toughness, durability, and other physical properties.

[0003] In existing testing machines, tensile testing requires manual placement of the specimen between two clamps. However, manual placement necessitates multiple fine adjustments to the specimen's position to ensure it is vertical and positioned in the center of the clamps, making the operation cumbersome. Utility Model Content

[0004] To address the issue of needing to make multiple fine adjustments to the position of the specimen during manual placement, the purpose of this invention is to provide a rapid calibration specimen clamp device for testing machines.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a rapid calibration sample clamp device for a testing machine, comprising a testing machine body, a support plate provided inside the testing machine body, clamp bodies provided at the bottom end of the support plate and on the lower surface of the inner wall of the testing machine body, and uniformly distributed mounting plates detachably mounted on the inner wall of the testing machine body, wherein threaded rods are fixedly provided on opposite sides of two of the mounting plates, and limiting rods are fixedly provided on opposite sides of the other two mounting plates, and a movable tube is threadedly sleeved on the outer side of the threaded rod, the outer side of the movable tube being movable. The device includes a movable plate, through which a limiting rod passes. A movable plate is movably mounted on the outer side of the limiting rod. The movable plate has symmetrically distributed slots inside, through which a locking rod moves. A fixed plate is fixedly mounted on the outer side of the locking rod. The fixed plate and the inner wall of the slot are fixedly connected by a spring. A first locking plate is fixedly mounted on the other end of the locking rod. A connecting plate is fixedly mounted on the top of the fixed plate. A limiting plate is movably mounted on the outer side of the connecting plate. The top of the movable plate has symmetrically distributed limiting slots. The limiting plate and limiting slots work together.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-4 As shown, this utility model provides a rapid calibration sample clamp device for a testing machine, including a testing machine body 1. A support plate 11 is provided inside the testing machine body 1. Clamp bodies 12 are provided at the bottom end of the support plate 11 and on the lower surface of the inner wall of the testing machine body 1. Evenly distributed mounting plates 13 are detachably installed on the inner wall of the testing machine body 1. Threaded rods 14 are fixedly provided on opposite sides of two mounting plates 13, and limiting rods 15 are fixedly provided on opposite sides of the other two mounting plates 13. A movable tube 16 is threadedly sleeved on the outer side of the threaded rod 14, and a movable plate 17 is movably provided on the outer side of the movable tube 16. The limiting rods 15 pass through the movable plate 17. A movable plate 18 is movably provided on the outer side of the limiting rod 15. The movable plate 18 has symmetrically distributed slots 19 inside. A locking rod 191 is movably passed through the slots 19. A fixing plate 192 is fixedly provided on the outer side of the locking rod 191. The fixing plate 192 and the inner wall of the slot 19 are fixedly connected by a spring 193. A first locking plate 194 is fixedly provided at the other end of the locking rod 191. A connecting plate 195 is fixedly provided at the top of the fixing plate 192. A limiting plate 196 is movably provided on the outer side of the connecting plate 195. A symmetrically distributed limiting groove 197 is provided at the top of the movable plate 18. The limiting plate 196 and the limiting groove 197 are used in conjunction.

[0018] The bottom of the movable plate 17 is fixedly equipped with symmetrically distributed positioning plates 2, which are distributed in an L-shape.

[0019] The top of the limiting plate 196 is fixedly provided with a locking block 3, and the outer side of the connecting plate 195 is provided with a stabilizing groove 31. The locking block 3 is movably locked in the stabilizing groove 31. By setting the locking block 3 and the stabilizing groove 31, the limiting plate 196 can move smoothly.

[0020] A protective pad 4 is fixedly provided on the outer side of the first card plate 194. By setting the protective pad 4, the first card plate 194 is prevented from damaging the sample strip and its service life is improved.

[0021] The first magnetic strip 5 and the second magnetic strip 51 are fixedly provided on the opposite sides of the movable plate 17 and the movable plate 18, respectively. By setting the first magnetic strip 5 and the second magnetic strip 51, the movable plate 17 and the movable plate 18 are more stably attached, and the position of the spline is avoided from shifting due to the displacement of the movable plate 18.

[0022] The mounting plate 13 is fixed with symmetrically distributed second clamping plates 6 on its outer side. The inner wall of the testing machine body 1 is provided with evenly distributed movable grooves 61. The second clamping plates 6 are movably clamped in the movable grooves 61. By setting the second clamping plates 6 and the movable grooves 61, the mounting plate 13 can be moved to facilitate its installation in different positions.

[0023] The mounting plate 13 has symmetrically distributed fixing holes 7 on its outer side. By setting the fixing holes 7, it is convenient for workers to install the mounting plate 13 with fixing screws.

[0024] The protective pad 4 is made of silicone, which increases friction with the sample and improves stability.

[0025] Working principle: In actual use, rotating the moving tube 16 drives the moving plate 17 to move until the moving plate 17 and one side of the clamp body 12 are on the same horizontal line. Then, the sample is placed in the middle of the movable plate 18, and the limiting plate 196 is removed from the limiting groove 197. At this time, the spring 193 releases its elastic force, driving the fixed plate 192 to move towards the sample. The fixed plate 192 drives the clamping rod 191 and the first clamping plate 194 to move until the two first clamping plates 194 fix the sample. Then, the movable plate 18 is pushed to move, so that the movable plate 18 moves closer to and fits against the moving plate 17, completing the process. The sample is quickly positioned and calibrated, and then clamped by the fixture body 12. By pushing the fixed plate 192 to move away from the first clamping plate 194, the clamping rod 191 and the first clamping plate 194 are moved until they are disengaged from the sample. Then, the limiting plate 196 is pushed to move and lock into the limiting groove 197, thus fixing the fixed plate 192, the clamping rod 191 and the first clamping plate 194. The positioning plate 2 allows the operator to see the position of the moving plate 17 more intuitively, making it easier for the moving plate 17 and the fixture body 12 to be kept on the same horizontal line, thus improving the user experience.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
