Description

Technical Field

[0001] The utility model relates to a silicone tensile testing machine, specifically a tensile testing machine for insulating silicone, belonging to the technical field of silicone tensile testing machines. Background Technique

[0002] The silicone tensile testing machine works based on the relationship between force and deformation. It measures the strength and deformation of the specimen by applying different loads, so as to determine the performance indicators of the material. During the test, the sample is clamped between two clamps, and then a load is applied in the vertical direction until the sample breaks. The force measuring system measures the tensile force of the specimen through a sensor and transmits the data to the control system for processing, so as to obtain performance indicators such as the tensile strength and elongation rate of the specimen.

[0003] In the prior art, such as a silicone tensile tester disclosed in CN212483180U, it clamps multiple silicone products through multiple clamping components, and then adjusts the distance between the sliding strip and the bearing strip through the distance adjusting component until the silicone product breaks, and then reads the scale through the scale line. The setting of multiple clamping components facilitates the simultaneous tensile test of multiple groups of silicone products.

[0004] However, in actual use, during the use of the above-mentioned silicone tensile tester, it clamps multiple silicone products through multiple clamping components, and the clamping components are the first clamp and the second clamp. Since the tensile test requires pulling the silicone, the silicone is easily detached after the clamp is pulled, and the clamping angle of the clamp has certain limitations, and the thickness that can be clamped is also limited.

[0027] Embodiment 2

[0028] In this embodiment, in addition to including all the technical features in Embodiment 1, it further includes:

[0029] Fixing structures 9 are provided inside both the upper fixing seat 6 and the lower fixing seat 7. The fixing structure 9 includes a pulling plate 901. A plug rod 902 is fixedly installed on the side of the pulling plate 901 close to the upper fixing seat 6 and the lower fixing seat 7. One end of the plug rod 902 penetrates through the mounting rod 801 and the upper fixing seat 6 and the lower fixing seat 7. A compression spring 903 is sleeved outside the plug rod 902. One end of the compression spring 903 is fixedly installed on the pulling plate 901, and the other end is fixedly installed on the upper fixing seat 6 and the lower fixing seat 7. A socket 10 matching the plug rod 902 is provided at the joint of the mounting rod 801 and the plug rod 902. The socket 10 is opened on the outside of the mounting rod 801. During the installation process, the mounting rod 801 is directly inserted at the upper fixing seat 6 and the lower fixing seat 7. The fixing of the mounting rod 801 is achieved by the elastically arranged pulling plate 901 and the plug rod 902 fixed at the pulling plate 901 inserted into the socket 10 at the mounting rod 801, thereby realizing the installation between the mounting rod 801 and the upper fixing seat 6 and the lower fixing seat 7.

[0030] An installation seat is provided at the connection between the bottom plate 1 and the lower fixed seat 7, and the lower fixed seat 7 is fixedly installed at the installation seat. A tension sensor 11 is fixedly installed at the installation seat, and the tension sensor 11 can achieve the monitoring effect of the tension during the tension test of the insulating silica gel by the lower fixed seat 6 and the upper fixed seat 7.

[0031] Working principle: First, insert the installation rod 801 at the upper fixed seat 6 and the lower fixed seat 7. When inserting the installation rod 801, it is necessary to pull the pull plate 901 to make the insertion rod 902 on one side of the pull plate 901 disengage from the upper fixed seat 6 and the lower fixed seat 7. Then, after the installation rod 801 is installed, release the pull plate 901, so that the compression spring 903 on one side of the pull plate 901 pulls the insertion rod 902 and the pull plate 901, and makes the insertion rod 902 insert into the socket 10 of the installation rod 801 to achieve the installation effect of the installation rod 801. Then, one end of the insulating silica gel can be placed on the clamping mechanism 8 at the lower fixed seat 7, and the hydraulic cylinder 3 is opened to make the hydraulic cylinder 3 push the slider 4 and the connecting block 12 to move in the moving guide groove. When the slider 4 and the connecting block 12 move, the bearing plate 5 connected to the slider 4 and the connecting block 12 will also move accordingly, and after the bearing plate 5 moves, it will drive the upper fixed seat 6 to move. At this time, the clamping mechanism 8 at the upper fixed seat 6 is moved to the other end of the insulating silica gel. Then, rotate the bidirectional screw 804. When the bidirectional screw 804 rotates, the two symmetrically arranged clamping plates 803 threadedly connected to the outside of the bidirectional screw 804 will move towards each other as the thread rotates. In this way, the insulating silica gel with different diameters, thicknesses or different shapes can be clamped by the clamping plates 803 moving towards each other. Subsequently, the hydraulic cylinder 3 is opened to make the hydraulic cylinder 3 pull the slider 4, the connecting block 12, the bearing plate 5 and the upper fixed seat 6 at the bearing plate 5 to move upward, so as to achieve the tension test of the insulating silica gel. During the test, the tension sensor 11 at the installation seat of the lower fixed seat 7 will perform tension detection as the hydraulic cylinder 3 continuously pulls.
