Description

Technical Field

[0001] This utility model belongs to the technical field of sealant performance testing devices, specifically, it relates to a performance testing device for organosilicon polymer sealants. Background Technology

[0002] Silicone polymer sealants are widely used in many fields such as construction, automotive, electronics, and aerospace due to their excellent resistance to high and low temperatures, weathering, chemical corrosion, and good adhesion and elasticity. As various industries continue to raise their performance requirements for sealants, more stringent standards are being set for the accuracy and comprehensiveness of their performance testing.

[0003] However, existing performance testing devices for silicone polymer sealants mostly involve bonding the sealant to two plates and then inserting the plates into the grooves of the testing device. This method fails to clamp the object being tested, making it prone to shaking or shifting during tensile or other performance tests. This results in inaccurate test data, and product quality assessments based on inaccurate data are likely to be misjudged. If shaking causes the tensile performance data of the sealant to be artificially inflated, substandard products may enter the market. After use in fields such as construction and automobiles, the sealant's actual performance may fail, leading to safety hazards such as sealing failure and structural damage. Conversely, if qualified products are misjudged as substandard due to shaking during testing, it results in wasted resources and losses for enterprises.

[0004] Therefore, in response to this problem, this utility model proposes a device for testing the performance of organosilicon polymer sealants. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a sealant performance testing device that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a silicone polymer sealant performance testing device, including a bracket with a protective shell, and further including: a T-shaped seat symmetrically fixedly connected inside the protective shell, a T-shaped threaded cylinder and a T-shaped disk symmetrically connected inside the protective shell; two sets of L-shaped plates are symmetrically connected between the T-shaped threaded cylinder and the T-shaped disk and the T-shaped seat, a bidirectional threaded rod is rotatably connected in the L-shaped plate, and a clamping plate is symmetrically threaded on the bidirectional threaded rod.

[0007] Preferably, the bidirectional threaded rod is symmetrically connected to the two sides of the first guide rod, and the clamping plate is slidably connected to the first guide rod.

[0008] Preferably, a threaded rod is rotatably connected inside the protective shell, the threaded rod is threadedly connected to a T-shaped threaded cylinder, and second guide rods are symmetrically connected on both sides of the threaded rod. One end of the second guide rod is fixedly connected inside the protective shell, and the other end of the second guide rod passes through the T-shaped threaded cylinder and is fixedly connected to a T-shaped seat.

[0009] Preferably, a first servo motor is fixedly connected to one end of the threaded rod that passes through the protective shell.

[0010] Preferably, the T-shaped disk is rotatably connected inside the protective shell, and a second servo motor is fixedly connected to one end of the T-shaped disk that penetrates the protective shell.

[0011] Preferably, a stop block is fixedly connected to the bidirectional threaded rod, and anti-slip grooves are provided at both ends of the bidirectional threaded rod.

[0012] Preferably, a rubber sheet is fixedly connected to one end of the clamping plate.

[0013] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: By rotating the bidirectional threaded rod at the end of the L-shaped plate, the present invention can drive the clamping plates on both sides to move synchronously and symmetrically towards each other along the first guide rod, using its unique left and right threaded structure. This ensures that the object being tested is subjected to uniform force during the clamping process, effectively avoiding the risk of eccentricity caused by uneven pressure on one side. Furthermore, the clamping can prevent the object being tested from shifting or shaking due to vibration or load changes during the testing process, further making the test data more accurate and representative.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] Reference Figures 1-5 The silicone polymer sealant performance testing device includes a bracket 1 with a protective shell 2, and further includes: a T-shaped seat 3 symmetrically fixedly connected inside the protective shell 2; a T-shaped threaded cylinder 31 and a T-shaped disk 32 symmetrically connected inside the protective shell 2; two sets of L-shaped plates 33 symmetrically connected between the T-shaped threaded cylinder 31 and the T-shaped disk 32 and the T-shaped seat 3; a bidirectional threaded rod 34 rotatably connected in the L-shaped plate 33; and clamping plates 35 symmetrically threaded on the bidirectional threaded rod 34; the object to be tested is placed in the corresponding upper and lower L-shaped plates 33, and then the bidirectional threaded rod 34 is rotated to bring the clamping plates 35 closer together to clamp the object to be tested, preventing shaking or displacement during the testing process.

[0024] The bidirectional threaded rod 34 is symmetrically connected to the first guide rod 36 on both sides. The clamping plate 35 is slidably connected to the first guide rod 36. The rotation of the bidirectional threaded rod 34 causes the clamping plate 35 to slide horizontally on the first guide rod 36, making the clamping process more stable.

[0025] A threaded rod 4 is rotatably connected inside the protective shell 2. The threaded rod 4 is threadedly connected to the T-shaped threaded cylinder 31. Second guide rods 41 are symmetrically connected on both sides of the threaded rod 4. One end of the second guide rod 41 is fixedly connected inside the protective shell 2, and the other end of the second guide rod 41 passes through the T-shaped threaded cylinder 31 and is fixedly connected to the T-shaped seat 3. The rotation of the threaded rod 4 causes the T-shaped threaded cylinder 31 to move upward, and the movement is more stable under the action of the second guide rod 41.

[0026] The threaded rod 4 is fixedly connected to one end of the protective shell 2. The first servo motor 5 drives the threaded rod 4 to rotate. The first servo motor 5 is mounted on the protective shell 2.

[0027] The T-shaped disk 32 is rotatably connected inside the protective shell 2. A second servo motor 6 is fixedly connected to one end of the T-shaped disk 32 that passes through the protective shell 2. The second servo motor 6 drives the T-shaped disk 32 to rotate. The second servo motor 6 is mounted on the protective shell 2.

[0028] A stop 37 is fixedly connected to the bidirectional threaded rod 34. Anti-slip grooves are provided at both ends of the bidirectional threaded rod 34. When clamping the object to be tested, the bidirectional threaded rod 34 is rotated, and the anti-slip grooves can play an anti-slip role.

[0029] A rubber sheet is fixedly connected to one end of the clamping plate 35. When the clamping plate 35 clamps the object to be detected, the rubber sheet can play a role in anti-slip and cushioning.

[0030] In use, the blocks of the colloid to be tested are placed into the L-shaped plates 33 at two different workstations. Then, the bidirectional threaded rod 34 is rotated to bring the clamping plates 35 closer together, firmly clamping the object to be tested and preventing displacement and vibration during the testing process, greatly increasing the accuracy of the test. When testing tensile properties, the first servo motor 5 is activated to rotate the threaded rod 4, which in turn moves the T-shaped threaded cylinder 31 upwards, further moving the corresponding upper and lower L-shaped plates 33 away from each other, thus allowing the tensile properties of the colloid to be tested. When testing the shear properties of the colloid, the second servo motor 6 is activated to rotate the T-shaped disk 32, causing the corresponding upper and lower L-shaped plates 33 to rotate, thus allowing the shear properties of the colloid to be tested. This novel experimental design can test both the tensile and shear properties of the colloid, avoiding the need to change clamps, making the test more convenient and faster, and saving testing time.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
