Description

Technical Field

[0001] This utility model relates to the technical field of adhesive testing equipment, specifically a stable structure for adhesive testing equipment. Background Technology

[0002] Adhesive testing equipment is a specialized instrument used to evaluate the performance of adhesives. It primarily tests key parameters such as viscosity, curing time, bond strength, and aging resistance. Common equipment includes viscometers, tensile testing machines, curing time testers, and thermal aging chambers, which can simulate the effects of different environmental conditions (such as temperature and humidity) on adhesive performance. This equipment is widely used in industries such as automotive, electronics, construction, and packaging to ensure that adhesives meet process requirements and quality standards, providing data support for product development and production quality control. Some high-end equipment also features automated operation and data analysis capabilities, improving testing efficiency and accuracy.

[0003] The prior art patent application number is 201921968971.X, entitled "Glue Viscosity Tester," which includes a base, a viscometer, an adapter assembly, and a test head. The viscometer has an output shaft at its bottom. The adapter assembly includes a connecting rod, a limiting cylinder, a separating pressure rod, a torsion spring, and two clamping hooks. The connecting rod is hinged to the output shaft, and the limiting cylinder passes through the connecting rod away from the output shaft. A receiving groove is formed on the end of the connecting rod away from the output shaft. The two clamping hooks are hinged together, and the torsion spring is located within the receiving groove. The separating pressure rod is located on the limiting cylinder. A positioning groove is formed on the outer wall of the test head, and the second ends of both clamping hooks are fastened into the positioning groove. The test head is fixed by clamping with two hooks on the adapter assembly, which allows the rotation direction of the test head to be unrestricted, thus improving the test accuracy. The clamping hooks replace the threaded connection for fixing the test head, which also allows the rotation direction of the test head to be unrestricted. Pressing the release lever releases the two clamping hooks to release the test head, which simplifies the fixing method of the test head and improves the replacement efficiency of the test head. However, the process or adhesive performance test results are not stable. The lack of a stable mechanical structure makes it difficult to effectively isolate external interference factors such as ground vibration. These environmental disturbances will directly affect the molecular arrangement and cross-linking reaction during the curing process of the adhesive, resulting in uneven curing rate and abnormal internal stress distribution. At the same time, in the adhesive performance test stage, small vibrations will introduce additional shear force, and temperature fluctuations may change the material expansion coefficient, ultimately causing significant deviations in the test data. Therefore, we propose a stable structure for adhesive testing equipment. Utility Model Content

[0004] The purpose of this invention is to provide a stable structure for adhesive testing equipment, in order to solve the problem mentioned in the background art of lacking a stable mechanical structure, making it difficult to effectively isolate external interference factors such as ground vibration, which ultimately leads to significant deviations in test data.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable structure for an adhesive testing device, comprising a base and a support plate, wherein the support plate is located above the base, four mounting plates are fixedly connected to the outer side of the base, a through groove is formed on the top of the mounting plate, a friction sleeve is fixedly connected to the inner side of the through groove, five mounting slots are formed on the top of the base and are evenly distributed, a damping cylinder is fixedly connected to the inner cavity of the mounting slot, the inner cavity of the damping cylinder is filled with damping oil, and a sealing ring is bonded to the top of the damping cylinder.

[0006] As a further description of the above technical solution:

[0007] A pressure rod is inserted into the top of the damping cylinder, and the top of the pressure rod is fixedly connected to the bearing plate.

[0008] As a further description of the above technical solution:

[0009] The bottom end of the pressure rod passes through the damping cylinder and extends into the inner cavity of the damping cylinder.

[0010] As a further description of the above technical solution:

[0011] The bottom end of the pressure rod is fixedly connected to a pressure plate, and the top of the pressure plate has through holes that are evenly distributed.

[0012] As a further description of the above technical solution:

[0013] A return spring is fixedly connected to the top circumference of the damping cylinder, and the return springs are evenly distributed. The top of the return spring is fixedly connected to the bearing plate.

[0014] As a further description of the above technical solution:

[0015] A bracket is fixedly connected to the top of the support plate, and four fixing plates are fixedly connected to the outside of the support plate.

[0016] As a further description of the above technical solution:

[0017] A friction plate is fixedly connected to the bottom of the fixing plate, the bottom of the friction plate extends to the bottom of the mounting plate, and the friction plate is in contact with the friction sleeve.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This adhesive testing equipment uses a stable structure. When the testing equipment is affected by external vibration, the bearing plate is subjected to pressure on the pressure rod connected to it, causing the pressure rod to move downward. This causes the pressure plate at the bottom of the pressure rod to squeeze the damping oil in the damping cylinder, allowing the damping oil to flow through the through hole on the pressure plate to the other side of the pressure plate. In this process, damping force is generated. At the same time, as the bearing plate moves downward, the return spring installed between the damping cylinder and the bearing plate is compressed, buffering the vibration. After the vibration is buffered, the return spring returns and extends, causing the bearing plate to rise. This causes the pressure rod to drive the pressure plate to rise, allowing the damping oil to flow back through the through hole, generating damping force again. Thus, it can effectively buffer and offset external vibration.

[0020] 2. This adhesive testing equipment uses a stable structure. When the support plate descends, the fixed plate installed on the support plate moves synchronously with the descent of the support plate, causing the friction plate at the bottom of the fixed plate to rub against the friction sleeve inside the mounting plate, generating damping force. When the support plate rises and resets, the friction plate at the bottom of the fixed plate will also rub against the friction sleeve inside the mounting plate, generating damping force again. This can generate additional damping force to further buffer and offset external vibrations. Attached Figure Description

[0030] This invention provides a stable structure for adhesive testing equipment, which can effectively buffer and offset external vibrations, and can generate additional damping force to further buffer and offset external vibrations. Please refer to [link / reference]. Figure 1-5 It includes a base 100 and a support plate 200;

[0031] Please refer to it again. Figure 1-5Four mounting plates 110 are fixedly connected to the outer side of the base 100. A through groove 111 is formed on the top of each mounting plate 110. A friction sleeve 112 is fixedly connected to the inner side of the through groove 111. Five mounting slots 120 are formed on the top of the base 100 and are evenly distributed. A damping cylinder 130 is fixedly connected to the inner cavity of each mounting slot 120. The inner cavity of the damping cylinder 130 is filled with damping oil 131. A sealant is adhered to the top of the damping cylinder 130. A pressure rod 140 is inserted into the top of the damping cylinder 130 (circle 132). The top of the pressure rod 140 is fixedly connected to the bearing plate 200. The bottom end of the pressure rod 140 passes through the damping cylinder 130 and extends into the inner cavity of the damping cylinder 130. A pressure plate 141 is fixedly connected to the bottom end of the pressure rod 140. Through holes 142 are evenly distributed around the top of the pressure plate 141. A return spring 150 is fixedly connected around the top of the damping cylinder 130. Springs 150 are evenly distributed. The top of the return spring 150 is fixedly connected to the support plate 200. When the test equipment is affected by external vibration, the support plate 200 is affected by the vibration and applies pressure to the pressure rod 140 connected to it, causing the pressure rod 140 to move downward and the pressure plate 141 at the bottom of the pressure rod 140 to squeeze the damping oil 131 in the damping cylinder 130. The damping oil flows through the through hole 142 on the pressure plate 141 to the other side of the pressure plate 141, generating damping force in the process. At the same time, as the support plate 200 moves downward, the return spring 150 installed between the damping cylinder 130 and the support plate 200 is compressed to buffer the vibration. After buffering the vibration, the return spring 150 returns and extends, causing the support plate 200 to rise. The pressure rod 140 drives the pressure plate 141 to rise, allowing the damping oil 131 to flow back through the through hole 142 and generate damping force again.

[0032] In summary, it can effectively buffer and offset external vibrations;

[0033] Please refer to it again. Figure 1-5 The support plate 200 is located above the base 100. A bracket 210 is fixedly connected to the top of the support plate 200. Four fixing plates 220 are fixedly connected to the outer side of the support plate 200. A friction plate 230 is fixedly connected to the bottom of the fixing plate 220. The bottom of the friction plate 230 extends to the bottom of the mounting plate 110 and contacts the friction sleeve 112. When the support plate 200 descends, the fixing plate 220 installed on the support plate 200 moves synchronously with the descent of the support plate 200, so that the friction plate 230 at the bottom of the fixing plate 220 rubs against the friction sleeve 112 in the mounting plate 110, generating a damping force. When the support plate 200 rises and resets, the friction plate 230 at the bottom of the fixing plate 220 will also rub against the friction sleeve 112 in the mounting plate 110, generating a damping force again.

[0034] In summary, additional damping force can be generated to further buffer and offset external vibrations;

[0035] In practical use, when the testing equipment is affected by external vibration, the bearing plate 200, under the influence of vibration, applies pressure to the pressure rod 140 connected to it, causing the pressure rod 140 to move downward. This causes the pressure plate 141 at the bottom of the pressure rod 140 to squeeze the damping oil 131 in the damping cylinder 130, causing the damping oil to flow through the through hole 142 on the pressure plate 141 to the other side of the pressure plate 141. During this process, damping force is generated. At the same time, as the bearing plate 200 moves downward, the return spring 150 installed between the damping cylinder 130 and the bearing plate 200 is compressed, buffering the vibration. After buffering the vibration, the return spring 150... The 0 is reset and extended, causing the bearing plate 200 to rise, which in turn causes the pressure rod 140 to drive the pressure plate 141 to rise, allowing the damping oil 131 to flow back through the through hole 142 and generate damping force again. When the bearing plate 200 descends, the fixed plate 220 installed on the bearing plate 200 moves synchronously with the descent of the bearing plate 200, causing the friction plate 230 at the bottom of the fixed plate 220 to rub against the friction sleeve 112 in the mounting plate 110, generating damping force. When the bearing plate 200 rises and resets, the friction plate 230 at the bottom of the fixed plate 220 will also rub against the friction sleeve 112 in the mounting plate 110, generating damping force again.
