Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] In a specific embodiment, as Figure 1 - Figure 2 shown, to solve the problem that the existing device does not have temperature and humidity detection;

[0033] Base 1 and support frame 2 fixedly installed at the upper end of base 1;

[0034] A control board 3 is fixedly installed on the outside of the support frame 2, and a humidity sensor 4, a temperature sensor 5 and a hydraulic push rod 6 are fixedly installed inside the upper end of the support frame 2. The lower end of the hydraulic push rod 6 is fixedly installed with a fixing plate 7, and a driving motor 8 is fixedly installed on the upper end of the fixing plate 7. The output end of the driving motor 8 is fixedly installed with a friction block 9;

[0035] A slider 10 is slidably installed at the upper end of the base 1, a sliding plate 11 is fixedly installed at the upper end of the slider 10, and an electric cylinder 12 is fixedly installed at the lower end of the sliding plate 11.

[0036] When using this device for testing the wear resistance of the paint surface of a board, it is necessary to install the board to be tested for paint surface wear resistance on the upper end of the mounting plate 30. Then, the data detected in real time by the humidity sensor 4 and the temperature sensor 5 can be observed through the control board 3. Then, the friction block 9 can be lowered to rub against the paint surface on the upper end of the board, so as to complete the detection of the paint surface of the board by this device. By detecting the temperature and humidity, the accuracy of the wear resistance test of this board can be improved.

[0037] In one of the specific embodiments, as Figure 1 - Figure 5 shown, to solve the problem that it is difficult for the existing device to accurately control the force;

[0038] The upper end of the base 1 is provided with a detection structure, and the detection structure can achieve the effect of accurately detecting the force on the plate.

[0039] Inside the detection structure, there are a fixed rod 13 and a fixed cylinder 14. The fixed rod 13 is fixedly installed at the lower end of the fixed plate 7, and the fixed cylinder 14 is slidably installed on the outside of the fixed rod 13. And at the lower end inside the fixed cylinder 14, there is a strong spring 15. Inside the base 1, a pressure sensor 16 is nestedly installed, and the pressure sensor 16 is located at the lower end of the fixed cylinder 14.

[0040] At the upper end of the sliding plate 11, a fixing member 17 and a driving motor 18 are fixedly installed. The output end of the driving motor 18 is fixedly installed with an output shaft 19, and the output shaft 19 is rotationally connected to the fixing member 17. And inside the fixing member 17, a rotating rod 20 is rotationally installed. At the same time, bevel gears one 21 are fixedly installed on the outside of the rotating rod 20 and the output shaft 19.

[0041] At the upper end of the fixing member 17, a rotating shaft 22 is rotationally installed. And on the outside of the rotating shaft 22, a lifting cylinder 23 is threadedly installed. And at the lower end of the rotating shaft 22, a bevel gear two 24 is fixedly installed. At the same time, the bevel gear two 24 is meshed with the bevel gear one 21. At the upper end of the lifting cylinder 23, a mounting plate 30 is fixedly installed.

[0042] When using this device for testing the wear resistance of the paint on the plate, according to the different materials of the plate, it is necessary to control the force on the paint surface of the plate. At this time, it is necessary to control the extrusion force of the friction block 9 on the plate. At this time, the hydraulic push rod 6 will expand and drive the friction block 9 to move downward through the fixed plate 7 and extrude the plate. During the process of the plate being extruded, the fixed rod 13 will move downward inside the fixed cylinder 14 and extrude the strong spring 15. After being extruded, the strong spring 15 will contract and transmit the pressure generated by the fixed rod 13 to the pressure sensor 16 through the fixed cylinder 14. At this time, the pressure generated by the pressure sensor 16 will be displayed inside the control board 3.

[0043] At this time, the driving motor 18 will work and drive the rotating rod 20 to rotate through the output shaft 19 and the pulley structure on the outside of the output shaft 19, so that the bevel gear one 21 can drive the bevel gear two 24 to rotate, thereby making the rotating shaft 22 rotate inside the lifting cylinder 23. And the lifting cylinder 23 will drive the mounting plate 30 to move upward and make the plate on the upper end of the mounting plate 30 just contact with the friction block 9. And the pressure between the friction block 9 and the plate is the same as the pressure received by the pressure sensor 16. By controlling the positions of the fixed plate 7 and the mounting plate 30, the pressure generated between the plate and the friction block 9 can be changed, so as to achieve the effect that this device can change the friction force of the paint surface of the plate.

[0044] Based on the above embodiments, as Figure 1 - Figure 3 and Figure 6 - Figure 7 shown, the problem that the existing device needs to rely on manual labor for disassembling and assembling the board is solved;

[0045] A limiting structure is provided inside the mounting plate 30, and the limiting structure can achieve the effect of automatically disassembling and assembling the board;

[0046] A limiting clamp block 26 is slidably mounted inside the mounting plate 30, and a return spring 27 is fixedly mounted on one side of the limiting clamp block 26 away from the middle position of the mounting plate 30;

[0047] One end of the limiting clamp block 26 away from the return spring 27 is fixedly mounted with a traction rope 28, and four groups of the limiting clamp block 26, the return spring 27 and the traction rope 28 are arranged at equal angles with respect to the midpoint of the mounting plate 30;

[0048] One end of the traction rope 28 away from the limiting clamp block 26 is fixedly mounted with a jacking block 25, and an electric push rod 29 is fixedly mounted at the lower end of the jacking block 25, and the electric push rod 29 is fixedly mounted on the upper end of the sliding plate 11.

[0049] When using the device for testing the wear resistance of the board paint surface, it is necessary to first limit the board on the upper end of the mounting plate 30. Place the board on the upper end of the mounting plate 30, and then the electric push rod 29 can be contracted. During the contraction of the electric push rod 29, the jacking block 25 will move downward, and the movement of the jacking block 25 will pull the limiting clamp block 26 to slide inside the mounting plate 30 through the traction rope 28. During the sliding of the limiting clamp block 26, the return spring 27 will expand, and the limiting clamp block 26 will limit and clamp the board, so as to facilitate the friction test of the board. After the board is tested, the electric push rod 29 will expand and push the jacking block 25 upward. At this time, the expanded return spring 27 will contract and pull the limiting clamp block 26 to reset. During the reset process of the limiting clamp block 26, it will separate from the board. Then the jacking block 25 will continue to move downward and jack up the board, so that the board is separated from the mounting plate 30, thus completing the disassembly and assembly process of the board by the device, effectively improving the convenience of the board detection disassembly and assembly;

[0050] During the process of the device testing the friction of the board, the electric cylinder 12 can be telescoped to drive the slider 10 and the sliding plate 11 to slide reciprocally on the upper end of the base 1, so that the board and the friction block 9 move reciprocally to complete the performance test. At the same time, the driving motor 8 can drive the friction block 9 to rotate to complete the performance test of the friction block 9 on the board. By the two methods of testing the friction of the board paint surface, the applicable range of the device can be expanded, and the overall practicability is increased.

[0052] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
