Technical Field
[0001] This utility model relates to a stretching machine, and more specifically to a test stretching machine for chain processing. Background Technology
[0002] Chains, as a common transmission and conveying component, are widely used in machinery, automobiles, motorcycles, agricultural machinery, lifting and transportation, and many other fields. The tensile performance of chains is one of the important indicators for measuring the quality and service life of chains. Therefore, it is necessary to conduct tensile tests on chains using a testing tensile testing machine to detect performance parameters such as tensile strength, yield strength, and elongation, ensuring that chain products meet relevant standards and usage requirements. Traditional equipment clamping mechanisms usually use simple clamping structures, which have poor clamping stability for chains. During the stretching process, the chain is prone to slippage or displacement, making it inconvenient to test the tensile performance of the chain. Summary of the Invention

[0004] To achieve the above objectives, this utility model provides the following technical solution: a chain processing experimental tensile testing machine, comprising a frame, a worktable disposed within the frame; a vertical plate and a movable clamping mechanism disposed on the worktable; a tension sensor fixedly disposed on the vertical plate; a hook disposed at one end of the tension sensor; the movable clamping mechanism comprising a motor, a screw, a fixing rod, and a clamping seat; a mating block disposed on the clamping seat and detachably connected to the clamping seat; and the tension sensor electrically connected to a display instrument on the frame.
[0005] The present invention is further configured such that: a limiting block is fixedly installed on the workbench; the limiting block is connected to a fixing rod; an upper hole and a lower hole are provided on the clamping seat; the fixing rod passes through the lower hole; the screw passes through the upper hole; and one end of the screw is movably engaged with the vertical plate.
[0006] The present invention is further configured such that: a groove is provided on the clamping seat; a protrusion is provided on the mating block; the protrusion mates with the groove; a connecting screw is also provided on the mating block; the connecting screw connects the mating block and the clamping seat.
[0007] The present invention is further configured such that a vertical rod is provided between the clamping seat and the mating block.
[0008] The present invention is further configured such that: the vertical plate has a lower plate; the clamping seat has an upper plate; the upper plate and the lower plate are staggered.
[0009] The present invention is further configured such that: a partition plate is provided inside the frame; and the display instrument is located above the partition plate.
[0010] The present invention is further configured such that: the frame is provided with an opening door connected to the frame by a hinge; the opening doors are connected to each other by a magnet.
[0011] In summary, this utility model has the following beneficial effects: during testing, one end of the chain is first suspended on the hook, and the other end of the chain is placed between the clamping seat and the upright on the mating block to fix both ends of the chain. Then, the motor is started to drive the screw to rotate, thereby moving the clamping seat away from the vertical plate. The tension on the chain is displayed by the display instrument, which can record the force when the chain breaks, thus facilitating the testing of the chain's tensile properties.

Detailed Implementation
[0014] The present invention will be further described in detail below with reference to the accompanying drawings.
[0015] This embodiment discloses an experimental stretching machine for chain processing, such as... Figures 1 to 3 As shown, this utility model facilitates the testing of chain tensile properties. It includes a frame 1, within which a workbench 2 is installed. The workbench 2 has a vertical plate 3 and a movable clamping mechanism. A tension sensor 4 is fixedly installed on the vertical plate 3. A hook 5 is provided at one end of the tension sensor 4. The movable clamping mechanism includes a motor 6, a screw 7, a fixing rod 8, and a clamping seat 9. A mating block 10 is provided on the clamping seat 9 for detachable connection. The tension sensor 4 is electrically connected to a display instrument 11 on the frame 1.
[0016] By adopting the above technical solution: when it is necessary to test the tension of the chain, one end of the chain is hung on the hook 5, and then the other end of the chain is placed in the movable clamping mechanism. After the movable clamping mechanism moves away from the vertical plate 3, the chain is tightened, so that the chain can be tested for tension. The tension of the chain is displayed by the display instrument 11 through the tension sensor 4. The display instrument 11 can record the force when the chain breaks, so as to facilitate the testing of the chain's tensile performance.
[0017] like Figure 2 As shown, a limiting block 12 is fixedly installed on the workbench 2; the limiting block 12 is connected to the fixing rod 8; the clamping seat 9 has an upper hole 13 and a lower hole 14; the fixing rod 8 passes through the lower hole 14; the screw 7 passes through the upper hole 13; one end of the screw 7 is movably connected to the vertical plate 3.
[0018] By adopting the above technical solution: the limiting block 12 can restrict the clamping seat 9 to prevent it from getting too close to the motor 6. After the motor 6 starts, it drives the screw 7 to rotate. Since there is a fixed rod 8 on the clamping seat 9, the clamping seat 9 will make horizontal displacement, thereby stretching the chain and thus performing tensile performance testing on the chain.
[0019] like Figure 2 As shown, the clamping seat 9 has a groove 15; the mating block 10 has a protrusion 16; the protrusion 16 mates with the groove 15; the mating block 10 is also provided with a connecting screw 17; the connecting screw 17 connects the mating block 10 and the clamping seat 9.
[0020] like Figure 2 As shown, a vertical rod 18 is provided between the clamping seat 9 and the mating block 10.
[0021] By adopting the above technical solution: after the groove 15 and the protrusion 16 cooperate, the connection between the mating block 10 and the clamping seat 9 is stable. Then, the connecting screw 17 connects the mating block 10 and the clamping seat 9, thereby making the connection between the mating block 10 and the clamping seat 9 stable. The part of the chain located between the clamping seat 9 and the mating block 10 is located between the two uprights 18, thereby restricting the other end of the chain.
[0022] like Figure 2 As shown, the vertical plate 3 has a lower plate 19; the clamping seat 9 has an upper plate 20; the upper plate 20 and the lower plate 19 are staggered.
[0023] By adopting the above technical solution: a chain can be placed on the lower plate 19 and the upper plate 20. The chain is placed on the upper plate 20 and the lower plate 19 when it is not fully taut. The upper plate 20 and the lower plate 19 are staggered so that the chain can be placed better.
[0024] like Figure 1As shown, a partition plate 21 is provided inside the frame 1; the display instrument 11 is located above the partition plate 21.
[0025] By adopting the above technical solution, the partition plate 21 can divide the space inside the frame 1 and prevent the broken chain from damaging the display instrument upwards. As for the display instrument 11, there are no restrictions, as long as it can detect the force and record the data.
[0026] like Figure 1 As shown, the frame 1 is provided with an opening door 22 connected to the frame 1 by a hinge; the opening doors 22 are connected to each other by magnets.
[0027] By adopting the above technical solution: when conducting chain tensile performance testing, the frame 1 can be closed by opening the door 22. The door 22 is provided with an observation port, and a transparent plate is provided at the observation port so that people can see the situation inside the frame 1.
[0028] In summary, this utility model has the following beneficial effects: during testing, one end of the chain is first suspended on the hook 5, and the other end of the chain is placed between the clamping seat 9 and the upright 18 on the mating block 10 to fix both ends of the chain. Then, the motor 6 is started to drive the screw 7 to rotate, thereby making the clamping seat 9 move away from the vertical plate 3. The tension on the chain is displayed by the display instrument 11, which can record the force when the chain breaks, thus facilitating the testing of the chain's tensile properties.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
