Description

Technical Field:

[0001] The utility model relates to the technical field of wear resistance detection, in particular to a wear test detection device. Background Art:

[0002] The test of the wear resistance of materials, also known as friction test, is to conduct an accelerated friction test on the actual friction parts of products or materials, so as to test their friction resistance in a short time. Friction tests can be divided into different types according to different friction media of products, such as rubber, grinding wheel, sandpaper, chemical reagent, cotton cloth, paper tape, metal products, etc. Wear is a common phenomenon in the industrial field and daily life. There are many reasons for this phenomenon, including physical, chemical and mechanical reasons, mainly abrasive wear, adhesive wear (scuffing) and fatigue wear, etc. Wear is an important reason for material and energy loss.

[0003] In the industrial field, the test of wear resistance is usually completed by wear resistance test equipment. Currently, the wear resistance test equipment on the market generally uses one or more robotic arms with friction heads, and drives the robotic arms to move back and forth to conduct friction tests on products. For example, the utility model patent application with the patent publication number CN221426351U discloses a rubber alcohol wear resistance tester, which includes: a frame body, a test bottom plate, a movable frame, a support frame, a locking bolt, a friction head fixing rod and a friction head. The friction head fixing rod is movably arranged up and down at the front end of the support frame. The friction head is arranged at the bottom end of the friction head fixing rod. An adjustment knob, a transmission component and a clutch locking component are also arranged on the support frame. When the adjustment knob rotates, it can drive the friction head fixing rod to move up and down through the transmission component. The clutch locking component can lock or unlock the adjustment knob. When adjusting the height position of the friction head, the adjustment knob can be unlocked first through the clutch locking component, and then the adjustment knob can be directly rotated to drive the friction head fixing rod to move up and down through the transmission component, so as to adjust the height position of the friction head.

[0004] However, this existing rubber alcohol wear resistance tester still has the following deficiencies:

[0005] In this technical solution, the movable frame at the front end of the frame body moves back and forth, and drives the friction head to make frictional contact with the product in the test bottom plate to conduct the wear resistance test. The test bottom plate is fixed, but the moving direction of the movable frame is the horizontal back-and-forth movement, and the friction head contacts the product vertically downward. In such a structure, the direction of the force changes, the transmission effect is not good, the friction effect is not good, and further it will affect the test accuracy and service life. The friction head should be fixedly arranged, and the test bottom plate should be set to be movable relative to the friction head to improve the test stability and accuracy.

When the runner 5 rotates, the moving test plate 2 is driven back and forth through the linkage rod 6, so that the product in the test position 22 and the test rod 4 perform a friction test.

[0025] In the present utility model, by arranging a slide bar group 11 between the chassis 1 and the moving test plate 2, and driving the moving test plate 2 through the runner 5, the moving test plate 2 can move back and forth relative to the test rod 4 to perform a friction test on the product in the test position 22. In this way, in the "face-to-point" manner, the direction of the force will not be changed, the transmission effect is better, the friction effect can be effectively improved, and the moving test plate 2 moves more smoothly during movement, which can effectively improve the accuracy and stability of the test.

[0026] As shown Figure 2 in the figure, a chute 52 capable of accommodating the second universal joint 51 is formed on the runner 5, an adjusting screw 53 is inserted through the runner 5, the adjusting screw 53 extends into the chute 52 and one end is helically installed in a second screw hole 502 on the second universal joint 51. When the adjusting screw 53 is turned, the second universal joint 51 moves along the chute 52 to adjust the relative position between the second universal joint 51 and the first universal joint 21.

[0027] The adjusting screw 53 includes a threaded section 531 extending into the chute 52 and helically installed in the second screw hole 502 and a nut 532 integrally formed with the threaded section 531 and exposed outside the runner 5.

The positioning piece 25 can swing with the positioning pin 24 as the rotation center axis. Here, to prevent the product in the moving test plate 2 from accidentally sliding due to friction during the operation of the device and affecting the test accuracy, a positioning piece 25 is added to press and position the product. When in use, the positioning piece 25 is rotated counterclockwise by 90°, so that the positioning piece 25 presses and positions the product. After testing one product, the positioning piece 25 is rotated clockwise back and the next product is placed, and so on.

A through hole 34 is opened on the test rod positioning block 33. Here, the lifting arm 3 firmly clamps the test rod 4 through the lifting clamp 31 and the test rod positioning block 33, which can ensure that the test rod 4 will not be skewed or shaken during the test, ensuring the test stability.

A number of weights 44 for adjusting the friction force of the friction head 43 are sleeved on the shaft section 42. Here, the weights 44 are sleeved on the shaft section 42. When the weights 44 are pressed down by gravity, they will contact the blocking surface formed between the body section 41 and the shaft section 42, and then the shaft section 42 will push the friction head 43 to generate a greater friction force with the product. The more weights 44 are added, the greater the friction force between the friction head 43 and the product.

[0033] Of course, the utility model can also increase the number of vertical rods 12, lifting arms 3 and test rods 4 at the same time to realize the simultaneous testing of multiple products and improve the testing efficiency.
