Description
Technical Field
[0001] This utility model relates to the field of base plate technology, specifically to a wood flooring abrasion resistance testing device. Background Technology
[0002] After wood flooring is designed and manufactured, it needs to undergo quality testing, such as abrasion resistance tests, to simulate wear under different usage conditions and thus evaluate the abrasion resistance of the wood flooring. Existing testing equipment cannot flexibly adjust testing parameters, such as pressure and coefficient of friction. Utility Model Content
[0003] To achieve the above objectives, this utility model provides a wood flooring abrasion resistance testing device.
[0004] The technical solution adopted by this utility model is as follows:
[0005] A wood flooring abrasion resistance testing device includes a base, a plywood, a flooring sample, and a sanding disc. Sandpaper is adhered to the bottom of the sanding disc. Vertical columns are vertically fixed to both sides of the upper part of the base. The upper parts of the two columns are fixedly connected to the bottom of a crossbeam. Each end of the bottom of the crossbeam has a smooth rod, the upper and lower ends of which are fixed to the bottom of the crossbeam and the upper part of the base, respectively. The ends of the smooth rods pass through both ends of a cross frame and are slidably connected to the cross frame. A square frame is fixedly connected to the center of the upper part of the cross frame, and a motor is fixedly connected to the upper part of the square frame. The output shaft of the motor passes through the middle of the cross frame and is rotatably connected to the middle of the cross frame. The output shaft of the motor extends to the lower part of the cross frame. The output shaft of the motor is fixedly connected to the grinding disc. There is a gap between the upper part of the grinding disc and the bottom of the cross frame. The bottom of the lead screw is rotatably connected to the middle of the upper part of the square frame. There is a first round hole in the middle of the upper part of the cross beam. The lead screw passes through the first round hole. There is a gap between the lead screw and the first round hole. The lead screw is threadedly connected to the limit nut. The limit nut is above the cross beam. A groove is set in the upper part of the square frame. Weights are placed in the groove. Several weights are stacked on top of each other. Corrugated tube one and corrugated tube two are sleeved on the outer wall of each smooth rod. The upper and lower ends of corrugated tube one are fixedly connected to the lower part of the cross beam and the upper part of the cross frame, respectively. The upper and lower ends of corrugated tube two are fixedly connected to the lower part of the cross frame and the upper part of the base, respectively.
[0006] The outer wall of the smooth rod is fitted with a linear bearing, which is fixedly embedded inside the cross frame. The smooth rod is slidably connected to the cross frame through the linear bearing. The clamping plate includes a flat plate and a vertical plate. The flat plate has vertical plates on both sides. The flat plate and the vertical plates are an integral structure. A protrusion is provided in the upper middle part of the flat plate. A second circular hole is provided in the middle of the floor sample. The protrusion is inside the second circular hole. The two sides of the floor sample abut against the vertical plate.
[0007] The beneficial effects of this invention are as follows: Under constant pressure and within a specified time, the wear resistance of different flooring samples is assessed. The smaller the reduction in thickness of the flooring sample, the better its wear resistance. The wear resistance of the flooring is tested by adjusting the grit of the sandpaper, the motor speed, and the weight of the weights. The grit of the sandpaper simulates the coefficient of friction, the weight of the weights simulates pressure, and the motor rotation time simulates the friction time. These different parameters are used to test the wear resistance of the flooring. Attached Figure Description

Sandpaper 4 is pasted to the bottom of the sanding disc 5. Vertical columns 6 are fixedly connected to the upper sides of the base 1.

The bottom ends of the crossbeam 7 have smooth rods 8, with the upper and lower ends of the smooth rods 8 fixed to the bottom of the crossbeam 7 and the upper part of the base 1, respectively. The two ends of the smooth rods 8 pass through the two ends of a cross frame 9, and the smooth rods 8 are slidably connected to the cross frame 9. A square frame 10 is fixedly connected to the center of the upper part of the cross frame 9. A motor 11 is fixedly connected to the upper part of the square frame 10. The output shaft of the motor 11 passes through the middle of the cross frame 9 and is rotatably connected to the middle of the cross frame 9.

There is a gap between the upper part of the grinding disc 5 and the bottom of the cross frame 9. The bottom of the lead screw 12 is rotatably connected to the middle of the upper part of the square frame 10. The middle position of the upper part of the cross beam 7 has a first round hole 23. The lead screw 12 passes through the first round hole 23. There is a gap between the lead screw 12 and the first round hole 23. The lead screw 12 is threadedly connected to the limiting nut 13. The limiting nut 13 is above the cross beam 7. The upper part of the square frame 10 is provided with a groove 14. Weights 15 are placed in the groove 14. Several weights 15 are stacked on top of each other. The outer wall of each smooth rod 8 is fitted with a corrugated tube 16 and a corrugated tube 27. The upper and lower ends of the corrugated tube 16 are fixedly connected to the lower part of the cross beam 7 and the upper part of the cross frame 9, respectively. The upper and lower ends of the corrugated tube 217 are fixedly connected to the lower part of the cross frame 9 and the upper part of the base 1, respectively.
[0015] A linear bearing 18 is sleeved on the outer wall of the smooth rod 8. The linear bearing 18 is fixedly embedded inside the cross frame 9. The smooth rod 8 is slidably connected to the cross frame 9 through the linear bearing 18. The clamping plate 2 includes a flat plate 21 and a vertical plate 20.

The protrusion 19 is inside the second circular hole 22. The two sides of the floor sample 3 abut against the vertical plate 20.
[0016] Motor 11 is a servo motor. The area of the grinding disc 5 is larger than the area of the floor sample 3.
[0017] Working principle: The function of the limit nut 13 is to limit the maximum distance of descent of the grinding disc 5. The position of the limit nut 13 on the lead screw 12 can be adjusted. With a fixed weight 15, the motor 11 operates. The motor 11 is set to run for a specified time. After completion, the grinding disc 5 is lifted and the floor sample 3 is removed. The thickness of the floor sample 3 is measured, and the thickness before and after measurement is compared. This allows us to know the wear of different flooring types under constant pressure and within a specified time. The smaller the reduction in the thickness of the floor sample 3, the better the wear resistance of the flooring. Different grit sandpaper 4 can be used to adjust the grit of the sandpaper 4, the rotation speed of the motor 11, and the weight of the weight 15. The grit of the sandpaper 4 simulates the coefficient of friction, the weight 15 simulates the pressure, and the rotation time of the motor 11 simulates the friction time. These different parameters are used to test the wear resistance of the flooring.
