Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass fiber mesh fabric testing technology, specifically to a glass fiber mesh fabric performance testing device. Background Technology
[0002] The performance testing device for fiberglass mesh is a key piece of equipment used to evaluate various properties of fiberglass mesh. It mainly includes a tensile testing device and a breaking strength testing device. The tensile testing device can accurately measure the mechanical properties of fiberglass mesh during the tensile process, including key parameters such as tensile strength, elongation at break, and modulus of elasticity. These parameters are crucial for evaluating the quality, durability, and applicability of the mesh.
[0003] When performing tensile testing on fiberglass mesh, the two ends of the cut mesh sample are usually clamped with fixtures before the tensile testing device is started to apply tensile load to the sample. However, the clamps used to hold the mesh in the current tensile testing device have poor clamping effect. When the mesh is stretched, it is easy to slip out of the fixture if the force is too large, thus affecting the test results. Therefore, a performance testing device for fiberglass mesh is proposed.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0006] A performance testing device for fiberglass mesh includes a base, a U-shaped frame fixedly installed on the top of the base, a crossbar inside the U-shaped frame, a lifting assembly for raising and lowering the crossbar inside the base, a tension sensor fixedly installed at the bottom of the crossbar, connecting blocks fixedly installed on the top of the base and the bottom of the tension sensor, L-shaped plates I fixedly installed on the sides of the two connecting blocks close to each other, movable L-shaped plates II on the side of each L-shaped plate I, several equally spaced electric telescopic rods fixedly installed inside each L-shaped plate II on the side close to the L-shaped plate I, a U-shaped frame fixedly installed at the output end of each electric telescopic rod, clamps fixedly installed at both ends of each U-shaped frame, a rectangular groove opened inside each L-shaped plate I on the side close to the L-shaped plate II, a rectangular frame fixedly installed inside each rectangular groove, several adjustable limiting cones on the side of each rectangular frame close to the L-shaped plate II, and a fixing assembly for fixing the position of the limiting cones on each rectangular frame.
[0007] Furthermore, the lifting assembly includes a strip groove. The two symmetrical side walls inside the U-shaped frame are provided with strip grooves. A servo motor is fixedly installed on the top of the U-shaped frame corresponding to the position of each strip groove. The output end of each servo motor extends into the interior of the corresponding strip groove and is fixedly connected to a lead screw. A lifting block is threaded onto each lead screw. A crossbar is fixedly installed between two lifting blocks.
[0008] Furthermore, the fixing component includes a cross groove. Each rectangular frame has cross grooves on both sides of its interior wall. A cross block is movably installed in the middle of each pair of adjacent cross grooves, corresponding to the position of each limiting cone. Each cross block is fixedly connected to the adjacent limiting cone. Each rectangular frame has two clamping rods inside. Each clamping rod passes through all the cross blocks inside the corresponding rectangular frame. Both ends of each clamping rod pass through the corresponding rectangular frame and are fixedly connected to a block one. Two blocks two are fixedly installed on both sides of each rectangular frame. Each block one is threadedly connected to a bolt one. The tail end of each bolt one is threadedly connected to the interior of the adjacent block two.
[0009] Furthermore, each of the clamping plates has a pressing rod fixedly installed on the side away from the adjacent electric telescopic rod, and two pressing grooves are opened inside each L-shaped plate one on the side near L-shaped plate two.
[0010] Furthermore, each of the L-shaped plates has a groove on the side of its horizontal end near the L-shaped plate, and a slider is movably installed inside each groove. Each slider is fixedly connected to the adjacent L-shaped plate. Each slider has a threaded groove on its side wall. Each L-shaped plate has a bolt 2 threadedly connected to its horizontal end. The tail end of each bolt 2 extends into the corresponding groove, and the tail end of each bolt 2 is threaded into the adjacent threaded groove.
[0011] Furthermore, each of the L-shaped plates has a groove on the side of its horizontal end near the connecting block. Each groove has a connecting plate inside it. Each connecting plate is fixedly connected to the adjacent L-shaped plate. Each connecting plate has a fixing hole. Each fixing hole has a bolt three threadedly connected inside it. The tail end of each bolt three is threadedly connected to the bottom surface of the adjacent groove.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. This utility model utilizes the mesh-like shape of the fiberglass mesh. Therefore, when performing tensile testing on the fiberglass mesh, the distance between adjacent limiting cones can be adjusted according to the mesh size. Then, the two ends of the mesh are placed inside two L-shaped plates, and the mesh holes are fitted onto the limiting cones inside the two L-shaped plates. Next, each electric telescopic rod is controlled, causing the corresponding U-shaped frame and clamping plate to move closer to the mesh, thus clamping it. Then, the lifting assembly is controlled, causing the crossbar and tension sensor to move upwards. The upward movement of the tension sensor causes the corresponding connecting block, L-shaped plate one, and L-shaped plate two to move upwards simultaneously. Since the two ends of the mesh are clamped, the mesh will be stretched, and the testing personnel can observe the stretching of the mesh in real time. Attached Figure Description

[0022] like Figures 1 to 3As shown, a performance testing device for fiberglass mesh includes a base 1, a U-shaped frame 2 fixedly mounted on the top of the base 1, a crossbar 3 inside the U-shaped frame 2, a lifting assembly 4 for raising and lowering the crossbar 3 inside the base 1, a tension sensor 5 fixedly mounted on the bottom of the crossbar 3, connecting blocks 6 fixedly mounted on the top of the base 1 and the bottom of the tension sensor 5, and L-shaped plates 7 fixedly mounted on the sides of the two connecting blocks 6 that are close to each other. Each L-shaped plate 7 has a movable... L-shaped plate 2 8, each L-shaped plate 2 8 has several equidistantly distributed electric telescopic rods 9 fixedly installed on the side near L-shaped plate 1 7. A U-shaped frame 10 is fixedly installed at the output end of each electric telescopic rod 9. Clamping plates 11 are fixedly installed at both ends of each U-shaped frame 10. A rectangular groove 12 is formed on the side of each L-shaped plate 1 7 near L-shaped plate 2 8. A rectangular frame 13 is fixedly installed inside each rectangular groove 12. Several adjustable... Each rectangular frame 13 is equipped with a fixing component 15 for fixing the position of the limiting cone 14. It should be noted that since the fiberglass mesh is mesh-shaped, when performing tensile testing on the fiberglass mesh, the distance between each pair of adjacent limiting cones 14 can be adjusted according to the size of the mesh on the fiberglass mesh. Then, the two ends of the mesh are placed inside the two L-shaped plates 7 respectively, and the mesh holes on the mesh are fitted onto the limiting cones 14 inside the two L-shaped plates 7. Then, each electric telescopic rod 9 is controlled, and each electric telescopic rod 9 drives the corresponding U-shaped frame 10 and clamping plate 11 to move closer to the mesh, thereby completing the clamping work of the mesh. Then, the lifting component 4 is controlled, so that the lifting component 4 drives the crossbar 3 and the tension sensor 5 to move upward. The upward movement of the tension sensor 5 drives the corresponding connecting block 6, L-shaped plate 7, and L-shaped plate 8 to move upward synchronously. Since the two ends of the mesh are clamped at this time, the mesh will be stretched, and the tester can observe the stretching of the mesh in real time.
[0023] like Figure 1 As shown, the lifting assembly 4 includes a strip groove 401. The two symmetrical side walls of the U-shaped frame 2 are provided with strip grooves 401. A servo motor 402 is fixedly installed on the top of the U-shaped frame 2 corresponding to the position of each strip groove 401. The output end of each servo motor 402 extends into the interior of the corresponding strip groove 401 and is fixedly connected to a lead screw 403. A lifting block 404 is threaded onto each lead screw 403. The crossbar 3 is fixedly installed in the middle of the two lifting blocks 404. It should be noted that when the two servo motors 402 are started, they can drive the two lead screws 403 to reciprocate. The reciprocating rotation of each lead screw 403 can raise and lower the corresponding lifting block 404. The raising and lowering of the two lifting blocks 404 can make the crossbar 3 and the tension sensor 5 rise and fall synchronously.
[0024] like Figure 2 , Figure 3 As shown, the fixing component 15 includes a cross groove 1501. Each rectangular frame 13 has cross grooves 1501 on both sides of its interior wall, symmetrically arranged. A cross block 1502 is movably installed between each pair of adjacent cross grooves 1501, corresponding to the position of each limiting cone 14. Each cross block 1502 is fixedly connected to the adjacent limiting cone 14. Each rectangular frame 13 has two clamping rods 1503 inside, each clamping rod 1503 penetrating all the cross blocks 1502 inside the corresponding rectangular frame 13. Both ends of each clamping rod 1503 are fixedly connected to a block 1504 through the corresponding rectangular frame 13. Each rectangular frame 13 has two clamping rods 1504 fixedly installed on both sides of its interior wall. Two square blocks 1505 are installed. Each square block 1504 is threaded with a bolt 1506. The tail end of each bolt 1506 is threaded to the inside of the adjacent square block 1505. It should be noted that by moving the distance between each pair of adjacent cross blocks 1502, the movement of each cross block 1502 will drive the limiting cone 14 connected to it to move synchronously. Then, the tail end of each bolt 1506 is threaded to the inside of the adjacent square block 1505. The corresponding cross blocks 1502 are fixed to the current position by using two clamping rods 1503 so that the distance between each pair of adjacent limiting cones 14 is suitable for fitting the mesh holes on the mesh fabric.
[0025] like Figure 2 As shown, each clamping plate 11 has a pressing rod 16 fixedly installed on the side away from the adjacent electric telescopic rod 9. Each L-shaped plate 17 has two pressing grooves 17 on the side near the L-shaped plate 2 8. It should be noted that each clamping plate 11 can drive the corresponding pressing rod 16 to be placed inside the adjacent pressing groove 17. At this time, the pressing rod 16 can press the mesh fabric into the adjacent pressing groove 17. When stretching the mesh fabric, the stability of the mesh fabric clamping can be guaranteed.
[0026] like Figure 2 As shown, each L-shaped plate 7 has a groove 18 on the side of its horizontal end near the L-shaped plate 8. A slider 19 is movably installed inside each groove 18. Each slider 19 is fixedly connected to the adjacent L-shaped plate 8. Each slider 19 has a threaded groove 20 on its side wall. Each L-shaped plate 7 has a bolt 21 threadedly connected to its horizontal end. The tail end of each bolt 21 extends into the corresponding groove 18 and is threaded into the adjacent threaded groove 20. It should be noted that by rotating the tail end of each bolt 21 out of the corresponding threaded groove 20, the L-shaped plate 8 can be pulled to make the slider 19 slide inside the groove 18, thus exposing the internal structure of the corresponding L-shaped plate 7 for easy operation.
[0027] like Figure 2As shown, each L-shaped plate 7 has a groove 22 on the side of its horizontal end near the connecting block 6. Each groove 22 has a connecting plate 23 inside it. Each connecting plate 23 is fixedly connected to the adjacent L-shaped plate 8. Each connecting plate 23 has a fixing hole 24. Each fixing hole 24 has a bolt 25 threaded inside it. The tail end of each bolt 25 is threaded to the bottom surface of the adjacent groove 22. It should be noted that when the tail end of each bolt 21 is threaded to the inside of the adjacent threaded groove 20, and the tail end of each bolt 25 is threaded through the corresponding fixing hole 24 to the bottom surface of the adjacent groove 22, each L-shaped plate 8 can be effectively fixedly connected to the adjacent L-shaped plate 7.
[0028] In summary:
[0029] Because the fiberglass mesh is mesh-like, when performing tensile testing on the fiberglass mesh, the distance between each pair of adjacent limiting cones 14 can be adjusted according to the size of the mesh. Then, the two ends of the mesh are placed inside the two L-shaped plates 7, and the mesh holes on the mesh are fitted onto the limiting cones 14 inside the two L-shaped plates 7. Then, each electric telescopic rod 9 is controlled, and each electric telescopic rod 9 drives the corresponding U-shaped frame 10 and clamping plate 11 to move closer to the mesh, thereby completing the clamping work of the mesh. Then, the lifting assembly 4 is controlled, so that the lifting assembly 4 drives the crossbar 3 and the tension sensor 5 to move upward. The upward movement of the tension sensor 5 drives the corresponding connecting block 6, L-shaped plate 7, and L-shaped plate 8 to move upward synchronously. Since the two ends of the mesh are clamped at this time, the mesh will be stretched, and the testing personnel can observe the stretching of the mesh in real time.
