Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tensile testing machines, specifically a tensile testing machine for conveyor chain production. Background Technology
[0002] A conveyor chain is a mechanical device that uses a chain as its core transmission component and is driven by sprocket meshing to achieve continuous and stable transport of materials or goods. It is widely used in industrial production, logistics transportation, food processing, and other fields, and is a key component of automated production lines and material handling systems. Its main structure consists of chain links (rollers, bushings, pins, chain plates, etc.), with common types including roller chains, bushing chains, and toothed chains. The chain tension is adjusted to prevent slackness or excessive tightness, ensuring transmission stability. It supports the chain and materials, guiding the transport path, and can be designed in straight, curved, or circular layouts. Power transmission: The drive system (motor + reducer) drives the sprockets to rotate, and the sprockets drive the chain in a cyclical motion through toothed meshing. Material carrying: Attachments on the chain (such as scrapers and pallets) carry the materials, moving them along a preset track (horizontal, inclined, or vertical) to achieve transport from the starting point to the end point.
[0003] In modern industrial production, the conveyor chain is a key component for material transfer, and its mechanical properties directly affect the stable operation of the production line. Therefore, tensile testing machines are indispensable testing equipment in the production process of conveyor chains. During testing, the conveyor chain needs to be carefully installed and fixed on the working platform of the tensile testing machine with the help of various fixing components such as clamps and bolts. Since the conveyor chain has a two-end structure, the disassembly and assembly operations at both ends need to be performed a total of four times for each test. This process is not only cumbersome, but also requires technicians to spend a lot of time on precise alignment, tightening and disassembly. The frequent and complicated disassembly and assembly process not only significantly increases the testing time cost, but also greatly reduces the overall testing efficiency of the conveyor chain.

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.
[0020] Please see Figure 1-4 A tensile testing machine for conveyor chain production includes a base plate 1, a vertical testing frame 2 fixedly connected to the top of the base plate 1, a strain gauge tensile sensor 3 fixedly connected to the bottom of the inner wall of the vertical testing frame 2, a tensile testing hook plate 4 fixedly connected to the top of the strain gauge tensile sensor 3, a conveyor chain body 5 sleeved on the surface of the tensile testing hook plate 4, a tensile testing hook plate 6 set on the top of the conveyor chain body 5, the surface of the tensile testing hook plate 6 in contact with the surface of the conveyor chain body 5, and a tensile testing mechanism 7 fixedly connected to the top of the tensile testing hook plate 6.
[0021] Please see Figure 1-4 The four corners of the tension testing hook plate 26 are slidably connected with vertical rods 8, and the top of the vertical rods 8 is fixedly connected to the top of the inner wall of the vertical testing frame 2.
[0022] Furthermore, by setting the vertical rod 8, the tension detection hook plate 2 6 can be limited, preventing the tension detection hook plate 2 6 from tilting during the sliding process, which would cause the tension detection hook plate 2 6 to be unable to move stably, thus improving the use effect of the tension detection hook plate 2 6.
[0023] Please see Figure 1-4 The bottom of the vertical rod 8 is fixedly connected to a limiting block 9, which is located at the bottom of the tension detection hook plate 6.
[0024] Furthermore, by setting the limiting block 9, the tension detection hook plate 2 6 can be limited, preventing the tension detection hook plate 2 6 from falling off the surface of the vertical rod 8, thus improving the stability of the tension detection hook plate 2 6 in use.
[0025] Please see Figure 1-4 The top of the inclined block 72 is equipped with a pulley 10, which is movably connected to the inside of the U-shaped plate 71.
[0026] Furthermore, by setting the pulley 10, the U-shaped plate 71 and the pushing inclined block 72 can be isolated from contact, avoiding mutual wear between the U-shaped plate 71 and the pushing inclined block 72, thus improving the safety of the pushing inclined block 72 in use.
[0027] The specific implementation process of this utility model is as follows: When in use, the conveyor chain body 5 is moved into the interior of the vertical detection frame 2, the bottom of the conveyor chain body 5 is inserted into the surface of the tension detection hook plate 4, and the top of the conveyor chain body 5 is inserted into the top of the tension detection hook plate 6. At this time, the conveyor chain body 5 is quickly installed.
[0028] Start the electric cylinder 73, which drives the inclined block 72 to move forward. The inclined block 72 drives the U-shaped plate 71 to move upward. The U-shaped plate 71 drives the tension detection hook plate 2 6 to move upward. The tension detection hook plate 2 6, together with the tension detection hook plate 1 4, stretches the conveyor chain body 5. The tension detection hook plate 1 4 will be driven upward. The tension detection hook plate 1 4 generates tension on the working end of the strain gauge tension sensor 3. The strain gauge tension sensor 3 generates tension data.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
