[0002] The pendulum friction coefficient tester is a precision instrument used to measure the friction coefficient between solid materials. It is widely used in materials science, engineering technology, and quality control. Its basic working principle is to simulate the sliding of objects on the contact surface, measure the relationship between frictional force and normal force, and thus calculate the friction coefficient.

[0035] Working principle: When using this device, first install it on the surface of the object to be measured.

Then, unfold the folding leg 3 and pull the limiting rod 12 upward to disengage it from the slot 9. At this time, the spring 11 will immediately push the sliding plate 10, causing the insertion rod 8 to reset and insert into the folding leg 3, fixing the folding leg 3 and preventing it from moving randomly during use. Next, start rotating the leveling bolt 4 to level the actuator 1. Then, start fine-tuning the distance between the pendulum 6 and the object to be measured, so that the rubber sheet on the pendulum 6 contacts the object at the correct distance.

At this time, the slide rod 15 moves backward, and the baffle 16 begins to compress the second spring 17. When the connecting rod 5 reaches the horizontal direction, the second spring 17 will immediately push the baffle 16 to drive the slide rod 15 to reset, locking the fixing buckle 13 at the bottom of the slide rod 15. Then, by controlling the parameters of the execution controller 1, the slide rod 15 is pressed to disengage the fixing buckle 13. At this time, the connecting rod 5 rotates clockwise due to the weight of the pendulum 6 and comes into contact with the object being tested. The sensor inside the execution controller 1 will detect the coefficient of friction of the object being tested and display it on the display screen of the execution controller 1. The test is completed by taking the average value of multiple tests. After the test is completed, pull the plug rod 8 again to unlock and fold the folding leg 3. The operation is convenient and labor-saving.
