The internal rotation of the first sliding frame 7 is connected to the second translation screw 8, and the outside of the first sliding frame 7 is provided with a left testing head 9, and a right testing head 10 is provided on one side of the left testing head 9. The right testing head 10 is connected to the surface of the second sliding frame 11 by bolts. The first sliding frame 7 and the second sliding frame 11 are connected by a connecting frame 12. The first sliding frame 7 and the second sliding frame 11 are slidably connected to the slide groove on the surface of the testing platform 1 through the pulley opened at the bottom thereof.
[0023] The lower detection head 5 includes a movable ring 501 and a fixed ring 502. The movable ring 501 and the fixed ring 502 are connected by a hinge. A limiting block 503 is welded on the surface of the movable ring 501. A limiting buckle 504 is provided on the surface of the fixed ring 502. The limiting buckle 504 is welded to the surface of the fixed ring 502 through a spring 505.
[0024] In this embodiment, Figure 1 and Figure 2 As shown, the upper detection head 4 forms a transmission structure through the lifting screw 3 and forms a lifting motion above the lower detection head 5, and the upper detection head 4 and the lower detection head 5 are located on the same vertical center line; when the material to be detected is clamped between the upper detection head 4 and the lower detection head 5, the upper detection head 4 drives one end of the material to move upward through the transmission structure of the lifting screw 3, while the lower detection head 5 below clamps the other end of the material and is fixed on the surface of the detection platform 1. The positional relationship and structure of the distribution of the two can ensure the consistency of measurement and effectively avoid data errors caused by probe position deviation.
[0025] In this embodiment, Figure 1 and Figure 4As shown, the second translation screw 8 is connected to one side of the left detection head 9 by a bolt through the nut provided thereon, and the left detection head 9 forms a transmission structure on the surface of the first sliding frame 7 through the second translation screw 8, and the left detection head 9 and the right detection head 10 are located on the same horizontal center line, and the upper detection head 4 and the lower detection head 5 and the left detection head 9 and the right detection head 10 are cross-distributed; by adding the left detection head 9 and the right detection head 10 to provide a horizontal detection point for material detection, a more comprehensive understanding of the performance of the detected part in different directions can be obtained, and its performance level in different directions can be more accurately evaluated, which is helpful to discover possible directional weaknesses or defects and make the detection results more comprehensive.
[0026] In this embodiment, Figure 3 As shown, the movable ring 501 and the fixed ring 502 form an open-close structure, and the movable ring 501 and the fixed ring 502 are connected by a limit block 503 and a limit buckle 504; although the probe currently used for tensile strength detection is adjustable, it is semi-closed and prone to loosening during the pressure application process. The several sets of probes used to clamp the raw materials to be tested all adopt an open-close circular ring structure, which is convenient for docking materials of different sizes and improving the versatility of detection. At the same time, the material to be tested can be enclosed inside during the pressure application process, effectively avoiding the separation problem caused by loosening.
[0027] In this embodiment, Figure 1 、 Figure 3 and Figure 4 As shown, the surfaces of the upper detection head 4 and the left detection head 9 are respectively connected to the displacement sensor 13 in rotation, and the inner wall of the lower detection head 5 and the right detection head 10 are respectively provided with a force sensor 14; since the annular rubber core is annular in structure, when it is sleeved between the upper detection head 4 and the lower detection head 5 or between the left detection head 9 and the right detection head 10, since one side is fixed during the stretching process, the tension on one side of a point located on the fixed detection head will apply pressure to the surface of the force sensor 14 (model CYMH-1), and the displacement sensor 13 (model FSD22) moves accordingly with the detection head on the movable side to monitor the material in real time and provide accurate displacement data to improve the accuracy and stability of the tensile test.
[0028] In this embodiment, Figure 1 、 Figure 4 and Figure 5 As shown, the first sliding frame 7 and the second sliding frame 11 form a transmission structure on the surface of the detection platform 1 through the first translation screw 6; the sliding structure of the first sliding frame 7 and the second sliding frame 11 can not only detect at a fixed vertical position, but also use the transmission structure of the first translation screw 6 to realize lateral tension detection at different positions and angles, thereby enriching the dimensions and angles of detection and providing more basis for more accurate performance analysis and quality judgment.
[0029] The use method and advantages of this utility model: When the anti-loosening ring-type rubber core tensile testing equipment is used, the working process is as follows:
[0030] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, it is first explained that the force sensor 14 and the displacement sensor 13 are electrically connected to the external computer processing equipment, and the surface of the ring-shaped rubber core is pre-marked as a reference basis for the displacement of the subsequent stretching position. It should be noted that the structure of the upper detection head 4, the left detection head 9 and the right detection head 10 is consistent with the lower detection head 5. After the two ends of the ring-shaped rubber core are respectively sleeved on the movable side of the opened upper detection head 4 and the lower detection head 5 after opening and closing, the upper detection head 4 and the lower detection head 5 are closed by the engagement structure of the limit buckle 504 and the limit block 503. Since the limit block 503 is located on one side of the movable ring 501, and one side of the surface of the upper detection head 4 The movable end is relatively distributed with the lower detection head 5, so when pressure is applied, it has strong stability and will not cause the limit buckle 504 to loosen. After turning on the power, the lifting screw 3 rotates and pulls the upper detection head 4 upward under the drive of the servo motor, thereby driving one end of the ring-shaped rubber core to stretch upward. In the process of movement, the surface of the ring-shaped rubber core is deformed, and the pre-marked position will be displaced accordingly. The displacement sensor 13 rises together with the upper detection head 4 to monitor in real time, and converts the deformation generated on the material surface into a corresponding electrical signal and transmits it to the external computer system. The external computer system uses the processed signal data to perform deformation analysis Analysis, through deformation analysis, we can understand the deformation of rubber materials during the stretching process, evaluate their mechanical properties and durability, and at the same time, the other end of the corresponding annular rubber core applies pressure to the surface of the force sensor 14, which will generate a corresponding electrical signal, which is transmitted to the external computer system in the same way for data analysis. After completing the fixed detection of the vertical position, the upper detection head 4 can drive the raw material to a certain position through the lifting screw 3. The transmission structure of the first translation screw 6 makes the first sliding frame 7 and the second sliding frame 11 drive the front end to the maximum running distance. The maximum transmission distance is the intersection of the center lines of the cross-distributed probes, and then The material to be tested is sleeved between the left test head 9 and the right test head 10. After the installation is completed, the second translation screw 8 can be used to drive the stretching of the left test head 9 to monitor the detection of the lateral position fixed point. At the same time, the first translation screw 6 transmission structure can be used again to make the left test head 9 and the right test head 10 drive the annular rubber pad to move. Since the other two ends of the annular rubber pad are fixed between the upper test head 4 and the lower test head 5, and the upper test head 4 and the lower test head 5 are fixed structures, the left test head 9 and the right test head 10 will generate a certain pulling force during the movement, thereby realizing lateral tension detection at different positions and angles, thereby enriching the detection dimensions and angles.
