Description

Technical Field

[0001] The utility model relates to the technical field of testing, and particularly relates to a damping performance tester for waterborne damping coatings. Background Technique

[0002] A damping performance tester is a performance device used to measure and evaluate various key performance parameters of damping materials, specifically for the damping effect of materials during vibration and impact.

[0003] The existing damping test device records and analyzes the damping times of a pendulum rod at a specific angle to obtain comparative data on the damping effect, and then calculates the damping performance of the damping coating. During this process, the swing of the pendulum rod will deviate due to the airflow in the external environment, which is not conducive to obtaining accurate damping data. Since the coating needs to be pretreated and attached during the test, and the test piece is not easy to replace. Therefore, those skilled in the art have provided a damping performance tester for waterborne damping coatings to solve the problems raised in the above background technique. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a damping performance tester for waterborne damping coatings, including a base. A damping test bench is fixedly installed at the front end of the base, and a fixed seat is fixedly installed at the upper end of the base. A damping propulsion component is fixedly installed at the front end of the fixed seat, and the damping propulsion component is arranged corresponding to the damping test bench.

[0005] The damping propulsion component includes a hydraulic device, a guide plate, a positioning column, a sleeve shaft, and a limit bolt. The hydraulic device passes through the top of the base and fixedly installs the guide plate. The guide plate can freely slide on the guide column, the movable column seat, and the movable column. A positioning column is fixedly installed in the middle of the lower end of the guide plate. A sleeve shaft is sleeved on the positioning column for the coating layer, and a limit bolt is arranged in the middle of the lower end of the positioning column to limit and lock the sleeve shaft.

[0006] Preferably, a plurality of bolt seats are fixedly installed on the lower side end of the damping test bench, and the base is fixed on the workbench surface through bolts cooperating with the bolt seats to prevent shaking during the test and affect the test results.

[0007] Preferably, the damping test bench includes a test bench cylinder, a damping inner hole, an air hole plate, an air groove, a guide column, a movable column seat, a movable column, and a hook. A vertically penetrating damping inner hole is opened in the middle of the test bench cylinder, and an air hole plate is fixedly installed at the bottom of the damping inner hole.

[0008] Preferably, an air groove is opened on the lower end surface of the test bench cylinder, so that during the damping test, the air flow in the damping inner hole can flow out from the air hole plate through the air groove, preventing the internal air pressure from being too large and affecting the test effect.

[0009] Preferably, a plurality of guide posts are annularly installed around the upper end of the test bench cylinder, and the guide posts are fixedly connected to the top of the base.

[0010] Preferably, movable column seats are symmetrically installed between the top of the base and the upper end face of the test bench cylinder. A movable column is movably arranged on the lower movable column seat. A hook is fixedly installed at the upper end of the movable column, and the hook is snap-connected to the upper movable column seat.

[0011] The technical effects and advantages of the present utility model:

[0012] When the present utility model is in use, by rotating the movable column on the lower movable column seat, the hook is removed from the upper movable column seat, and the limiting bolt is rotated to remove the sleeve shaft from the positioning column, so as to replace the sleeve shaft pre-treated with different coatings. After the installation is completed, the guide plate can be driven to slide directionally along the direction of the guide post by the hydraulic device, so that the sleeve shaft enters the damping inner hole under the drive of the positioning column. Due to the damping friction with the damping inner hole, by adjusting the pressure supply coefficient of the hydraulic device, the damping performance strength of the precise damping coating can be obtained to judge the damping performance.
