Description

Technical Field

[0001] This utility model relates to a testing device for flocked springs, and more particularly to a measuring device for the flocking thickness of flocked springs. Background Technology

[0002] With the development of new energy vehicles, car tailgates have gradually evolved into electric tailgates. Electric tailgates often use electric struts during opening and closing. To improve the sound quality of these struts, flocked springs are commonly used inside. After the flock is applied to the spring surface, the flock thickness needs to be measured. However, traditional methods, such as using a micrometer, are limited by the spring's shape and can only measure the flock thickness at the two ends of the spring. Alternatively, the inspector may need to painstakingly cut the spring to measure the flock thickness in other areas. Furthermore, traditional methods require the inspector to hold the spring and fix the micrometer relative to it, which is difficult to operate. Because flocking is similar to hair and is very soft, excessive coarse adjustment of the micrometer can easily affect the accuracy of the measurement. Utility Model Content

The measuring device is as follows: Figure 3 As shown, the measuring device includes a circular limiting block 13, a test rod 14, and a cylindrical probe 15. The lower end of the circular limiting block 13 is snapped into the load plate 12. The upper end of the circular limiting block 13 is threaded into the lower end of the test rod 14. The upper end of the test rod 14 is threaded into the cylindrical probe 15. A threaded operating rod 9 is provided on one side of the load plate 12. A limiting post 1 is threaded into the lower fixed plate 16. The limiting post 1 is located below the load plate 12. A damper 7 is provided at the upper end of the load plate 12. Its upper end is snapped into the test table 10 by a ball joint, and its lower end is snapped into the load plate 12 by a ball joint.

[0019] The vertical fixing mechanism is a vertical fixing clamp 5, which includes a pressure block and an adjusting bolt.

[0020] The horizontal fixing mechanism includes a horizontal fixing clamp 6 and a limiting plate 11. The horizontal fixing clamp 6 includes a pressure block and an adjusting bolt.

[0021] The vertical fixing clamp 5 is connected to the test bench 10 by bolts. The vertical fixing clamp 5 provides a vertical fixing force to the sample 4 under test, keeping the spring tightly against the test bench to prevent spring twisting and fixing the position of the sample. The horizontal fixing clamp 6 is connected to the test bench 10 by bolts, keeping the spring of the sample 4 tightly against the limiting plate 11 to prevent spring twisting and fixing the position of the sample. The limiting plate 11 is connected to the test bench 10 by welding. The test bench 10 is connected to the support 3 by bolts. The lower fixing plate 16 is connected to the support 3 by bolts. The upper end of the damper 7 is connected to the test bench 10 by a ball joint snap-fit, and the lower end of the damper 7 is connected to the load plate 12 by a ball joint snap-fit. The load plate 12 mainly provides the load for pressing down the flocked material, and the damper 7 mainly prevents the load plate 12 from moving too quickly and damaging the equipment. The operating lever 9 is connected to the load plate 12 by threads. Rod 9 primarily controls the movement of the load plate 12. The sliding column 8 is threadedly connected to the test platform 10 and the lower fixed plate 16.

The test rod 14 is threadedly connected to the cylindrical probe 15.

[0022] The method of using the device for measuring the flocking thickness of flocked springs includes:

[0023] Step 1: Zero point confirmation: Control the load plate 12 to slide down on the sliding column 8 by moving the operating lever 9. The load plate 12 pulls down the cylindrical probe 15 to fit tightly against the test table 10 through the test link 14. Zero point confirmation is performed on the cylindrical probe 15, and the initial reading of the dial indicator 2 is recorded.

[0024] Step 2, Measuring flock thickness: Prepare the sample 4 to be tested, and scrape off the flock outside the three rings of wire diameter on the left and right sides of the test point of the sample 4. Place the sample 4 horizontally on the surface of the test table 10. Fix the sample 4 vertically by adjusting the vertical fixing clamp 5. Adjust the horizontal fixing clamp 6 to make the sample 4 fit tightly with the limiting plate 11 and fix the sample 4 horizontally. Remove the cylindrical probe 15 from the test connecting rod 14, then put it into the sample 4 and move it to the test point. Then connect the cylindrical probe 15 to the test connecting rod 14. Move the operating rod 9 downward. The load plate 12 transmits the downward pressure to the cylindrical probe 15 through the test connecting rod 14. Record the reading of the dial indicator 2.

[0025] The third step is to compare the absolute values ​​of the differences between the two readings to obtain the thickness of the flocking on the inner side of the sample 4 to be tested.

[0026] The above method can also be used to measure the spring wire diameter and the flocking thickness of the outer diameter.
