Description

TECHNICAL FIELD

[0001] The present application relates to the field of sealant testing, in particular to a sealant fatigue resistance testing device. BACKGROUND

[0002] The sealant fatigue resistance testing device is a machine for evaluating the performance of sealant under long-term use and cyclic stress, usually by applying force to the sealant to test the sealant.

[0003] In order to ensure that the measured results have reference value, the force received by the sealant needs to be measured when testing the sealant, so as to facilitate subsequent experimental data recording. Some existing sealant fatigue resistance testing devices can only measure the tensile force received by the sealant, but the influence of pressure is also great in the use of the sealant. If the sealant is subjected to excessive pressure in normal use, irreversible deformation will occur. Thus, the sealant may have insufficient elasticity and gaps between the adhered objects in subsequent use, thereby reducing the sealing performance of the sealant. Therefore, it is also important to measure the fatigue resistance of the sealant to pressure.

[0004] Therefore, it is necessary to provide a sealant fatigue resistance testing device capable of measuring the pressure received by the sealant to solve the problem that some sealant fatigue resistance testing devices cannot measure pressure. CONTENT OF THE INVENTION

[0034] The embodiments of the present application provide a sealing glue fatigue resistance test equipment, comprising:

[0035] support;

[0036] The testing mechanism comprises a servo motor, a transmission assembly and an upper clamp, one end of the transmission assembly is in transmission connection with the output end of the servo motor, and the other end is in detachable connection with the upper clamp;

[0041] The sealing glue fatigue resistance testing device provided above solves the problem that some sealing glue fatigue resistance testing devices cannot measure the pressure by arranging a pressure sensor between the fixed seat and the support, so that the pressure sensor can reflect the pressure received by the sealing glue when the sealing glue is fixed on the fixed seat and receives the pressure.

[0042] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0043] Please refer to Figures 1-4 The sealing glue fatigue resistance testing device 100 provided by the embodiments of the present application comprises a support 1, a testing mechanism 2, a fixed seat 3, a tension sensor 4 and a pressure sensor 5. The testing mechanism 2 comprises a servo motor 21, a transmission assembly 22 and an upper clamp 23, one end of the transmission assembly 22 is in transmission connection with the output end of the servo motor 21, and the other end is in detachable connection with the upper clamp 23. The fixed seat 3 is arranged on the support 1 and faces the upper clamp 23. The tension sensor 4 is arranged between the upper clamp 23 and the transmission assembly 22 and is used for measuring the tension received by the upper clamp 23. The pressure sensor 5 is arranged on the fixed seat 3. The sealing glue is fixed on the upper clamp 23 and the other end is fixed on the fixed seat 3. The servo motor 21 can drive the transmission assembly 22 to move, so that the upper clamp 23 moves towards or away from the fixed seat 3. The pressure sensor 5 and the tension sensor 4 can test the pressure and tension received by the sealing glue respectively, and the fatigue resistance of the sealing glue is calculated.

[0044] Specifically, the bracket 1 provides the basic structure and support of the device, ensuring the stability and accuracy of the test. The bracket 1 serves as the skeleton of the device, providing support for other components. The test mechanism 2 is used to control the movement of the upper clamp 23, simulating the use of sealant under different stresses. The servo motor 21 drives the movement of the upper clamp 23 through the transmission assembly 22, allowing it to move towards or away from the fixed seat 3. The fixed seat 3 is arranged opposite the upper clamp 23, so that the sealant can be clamped between the upper clamp 23 and the fixed seat 3. The fixed seat 3 and the upper clamp 23 clamp the two ends of the sealant respectively to apply force to the sealant. The tension sensor 4 and the pressure sensor 5 are used to measure the tension on the upper clamp 23 and the pressure on the sealant respectively, for calculating the fatigue resistance of the sealant. The sensors measure the force on the upper clamp 23 and the sealant respectively, providing data for subsequent analysis.

[0045] In a specific example, the transmission assembly 22 includes a lead screw 221, a limiting rod 222, and a limiting plate 223. One end of the lead screw 221 is in transmission connection with the output end of the servo motor 21, and the other end is in threaded connection with the limiting plate 223. The upper clamp 23 is arranged on the limiting plate 223, and the limiting rod 222 is arranged on the limiting plate 223, and the limiting rod 222 penetrates through the bracket 1.

[0046] Specifically, the lead screw 221, as part of the transmission assembly 22, converts the rotary motion of the servo motor 21 into linear motion, controlling the up-and-down movement of the upper clamp 23. A precise and controllable way is provided to ensure that the vertical movement of the upper clamp 23 has high accuracy and repeatability. The limiting rod 222 plays a supporting and stabilizing role, preventing excessive movement of the upper clamp 23 and ensuring the accuracy of the test. By using corrosion-resistant materials such as stainless steel, the durability and stability of the limiting rod 222 are improved, ensuring the reliability of the test. The limiting plate 223 connects the lead screw 221 and the upper clamp 23, and at the same time, through the transmission connection with the servo motor 21, realizes the control of the movement of the upper clamp 23. The design of the limiting plate 223 ensures the reliable connection between the lead screw 221 and the upper clamp 23, and at the same time, through the threaded connection, provides an adjustable mechanical structure, so that the test adapts to the needs in different situations. The upper clamp 23 is used to clamp the sealant, and through the connection with the limiting plate 223, participates in the up-and-down movement in the test process. The design of the upper clamp 23 ensures the fixation of the sealant, and the connection with the limiting plate 223 guarantees the stability of the upper clamp 23 in the test.

[0047] In a specific example, the upper clamp 23 includes a first clamp 231 and a second clamp 232, and the fixed seat 3 includes a third clamp 31 and a fourth clamp 32.

[0048] The first clamp 231 and the second clamp 232 are bolted together.

[0049] The third clamping piece 31 is bolted with the fourth clamping piece 32.

[0050] Specifically, the first clamping piece 231, the second clamping piece 232, the third clamping piece 31 and the fourth clamping piece 32 are collectively referred to as clamping pieces, which are components of the upper clamp 23 and the fixing seat 3, used for fixing the sealant and participating in the force transmission in the test process. The design of the clamping pieces makes the sealant receive uniform force in the test, and provides a stable clamping structure. The clamping pieces are bolted, which ensures the fastening and connection between the clamping pieces, making the structure of the whole upper clamp 23 and the fixing seat 3 more firm. The bolted connection provides a detachable structure, which is convenient for replacing or maintaining the clamping pieces, and also increases the adjustability of the system.

[0051] In a specific example, the first clamping piece 231 is provided with a first anti-skid groove 2311, the second clamping piece 232 is provided with a second anti-skid groove 2321, the third clamping piece 31 is provided with a third anti-skid groove 311, and the fourth clamping piece 32 is provided with a fourth anti-skid groove 321.

[0052] The first anti-skid groove 2311 is opposite to the second anti-skid groove 2321, and the second anti-skid groove 2321 is opposite to the fourth anti-skid groove 321.

[0053] Specifically, the first clamping piece 231, the second clamping piece 232, the third clamping piece 31 and the fourth clamping piece 32 are collectively referred to as clamping pieces, and the first anti-skid groove 2311, the second anti-skid groove 2321, the third anti-skid groove 311 and the fourth anti-skid groove 321 are collectively referred to as anti-skid grooves. The anti-skid grooves provided on the clamping pieces can effectively reduce the sliding of the upper clamp 23 during movement, and maintain the stability of the clamping structure. The provision of the anti-skid grooves ensures that the sealant receives more uniform force during the test, reduces unnecessary friction, and improves the accuracy of the test.

[0054] Further, the first anti-skid groove 2311 is opposite to the second anti-skid groove 2321, and the second anti-skid groove 2321 is opposite to the fourth anti-skid groove 321, which ensures that the anti-skid grooves between the clamping pieces are completely aligned, increasing the stability of the whole clamping structure. The opposite relationship between the anti-skid grooves ensures that the force received by the sealant during the test is uniformly distributed, preventing misalignment of the clamping structure and improving the accuracy of the test results.

[0055] In a specific example, the bracket 1 includes a base 12 and a crossbeam 11, the test mechanism 2 is arranged on the crossbeam 11, the fixing seat 3 is arranged on the base 12, and the base 12 and the crossbeam 11 are detachably connected.

[0056] Specifically, the base 12 and the crossbeam 11 are detachably connected, facilitating the assembly, disassembly and maintenance of the device. The maintainability of the device is improved, and the time and cost in the maintenance and repair process are reduced, while the transportation and storage of the device are facilitated.

[0057] In a specific example, the limiting rod 222 is made of stainless steel.

[0058] Specifically, the limiting rod 222, as a key component in the testing device, is made of stainless steel. Stainless steel has good corrosion resistance and can work stably in humid or corrosive environments for a long time, ensuring the long service life and reliability of the device. Stainless steel has high strength and can withstand large forces and pressures, ensuring the stability and safety of the limiting rod 222 during testing. The smooth surface of stainless steel is easy to clean, which helps to maintain the hygiene of the device, especially in the case of precise testing.

[0059] In a specific example, the limiting plate 223 is provided with a mounting hole 2231 for setting the upper clamp 23.

[0060] Specifically, the mounting hole 2231 provides a position for fixing and supporting the upper clamp 23, allowing controllable connection between the upper clamp 23 and the limiting plate 223. The setting of the mounting hole 2231 ensures that the upper clamp 23 can be accurately installed on the limiting plate 223, so that the movement of the upper clamp 23 during testing is more accurate and controllable. By selecting different mounting holes 2231, the position of the upper clamp 23 can be adjusted to accommodate sealant samples of different sizes or shapes, improving the applicability and flexibility of the device.

[0061] In a specific example, the fixing seat 3 is bolted to the pressure sensor 5.

[0062] Specifically, the bolt connection provides a reliable way to tightly fix the fixing seat 3 on the base 12 of the bracket 1. The bolt connection ensures the structural stability between the fixing seat 3 and the pressure sensor 5, so that the entire testing device remains stable during operation, helping to obtain accurate test results. The bolt connection facilitates disassembly and reconnection, making the maintenance and repair of the device more convenient and reducing maintenance costs.

[0063] In a specific example, the base 12 is provided with a handrail groove 121 for hand gripping.

[0064] Specifically, the setting of the handrail groove 121 takes into account the ergonomic principle, so that the operator can more naturally grip the base 12 when carrying the device. The operator can grip the handrail groove 121 to make the carrying process easier, reduce the physical burden during operation, and improve work efficiency.

[0065] In a specific example, the limiting rod 222 is integrally formed with the limiting plate 223.

[0066] Specifically, the integrally formed limiting rod 222 and limiting plate 223 mean that they are formed of the same material, providing higher rigidity and stability. This is crucial for maintaining strict position and motion control in the test equipment. Since the limiting rod 222 is integrally formed with the limiting plate 223, its structure is more robust, helping to ensure that there is no deformation or instability during the test process, thereby achieving more precise motion control. Integrally forming reduces the number of connecting components, reduces wear between parts, and improves the durability and reliability of the equipment.

[0067] The above is only an embodiment of the present application, and it should be pointed out that those of ordinary skill in the art can make improvements without departing from the inventive concept of the present application, but these all belong to the protection scope of the present application.
