Description

Technical Field

[0001] The present invention relates to the technical field of friction testing, and more particularly to a glass panel friction resistance testing device. Background Art

[0002] The principle of the glass panel friction resistance test device is mainly based on the principles of mechanics and tribology. It evaluates the wear resistance and mechanical strength of the glass panel by simulating the mechanical stress and friction that the glass panel is subjected to in actual use.

[0003] Patent publication number CN220650358U discloses a friction resistance test device for cover glass. This technology utilizes a weight support plate mounted on the top of a friction rod, with a removable friction joint at the bottom to secure the friction material to the rod. The rod is positioned above the glass. This device can simultaneously perform friction resistance tests on multiple glass samples, fully utilizing the internal space of the test chamber, improving test efficiency while ensuring a consistent test environment. However, this patent suffers from the following drawbacks:

[0004] The friction resistance test of glass panels requires applying mechanical stress for friction treatment. For curved glass panels, due to the complexity of the curved surface of the glass panels, to achieve vertical arc, inclined arc and rotation path, separate power equipment is required at each position to drive the test item by item. This makes it difficult to use the same power equipment to achieve multi-directional synchronous friction resistance testing on the curved surface. The existing method has obvious disadvantages. On the one hand, the efficiency of friction resistance testing in different directions is low, and the test process is time-consuming. On the other hand, since multiple separate devices are required, the production and use costs of the friction resistance test are greatly increased, which increases the economic burden of the test.

[0024] Technical effects and advantages of the present invention:

[0025] The present invention adopts an oblique arc synchronous friction test assembly and a vertical arc synchronous friction test assembly to carry out an oblique arc synchronous friction test, starts the linkage electric cylinder, causes the linkage bar to move back and forth up and down, thereby driving the oblique rope, oblique arc sleeve block, counterweight oblique block, linkage column, mounting sleeve and oblique arc friction block components to move back and forth up and down along the oblique direction arc path, ensuring that the oblique arc friction block moves back and forth along the oblique direction arc path along the outer wall of the test glass, and at the same time, the linkage bar moves upward to drive the top end of the vertical rope to move upward, thereby making the vertical sleeve, vertical column, mounting block and vertical arc friction block components move back and forth up and down The components move upward in a vertical arc path along the vertical arc track and the arc groove, so that the vertical arc friction block can move upward in a vertical arc path to rub the outer wall of the test glass. When the linkage bar moves downward, each component moves downward in a vertical arc path under the action of its own counterweight force to complete the downward friction test. The power source of the same linkage electric cylinder is used to realize multi-directional synchronous friction resistance tests on vertical arc paths and inclined arc paths, which not only makes the synchronous test more efficient, but also greatly reduces the cost of the friction resistance test and alleviates the economic burden of the friction resistance test.

[0026] When the linkage bar of the present invention moves downward, the oblique arc friction block rubs downward along the outer wall of the test glass in an inclined direction under the action of the counterweight oblique block, the oblique arc sleeve block, the linkage column and the mounting sleeve counterweight. When the linkage bar moves downward, the vertical arc path is moved downward under the action of the counterweight force of the vertical sleeve, the counterweight block, the vertical column and the mounting block. The vertical arc friction block rubs downward along the outer wall of the test glass in a vertical arc path. The counterweight force of the counterweight oblique block and the counterweight block components is used to provide downward friction force. No additional power source is required to drive the downward movement, which significantly reduces power source loss, makes the friction resistance test process more energy-efficient and efficient, and simplifies the equipment structure, reduces equipment cost and maintenance difficulty.

[0027] The present invention adopts a rolling path synchronous friction test assembly. When the linkage bar moves up and down, it synchronously drives the rack to move up and down. The rack drives the gear to rotate clockwise or counterclockwise, thereby driving the rotating rod and the test friction roller to rotate. The test friction roller performs a clockwise or counterclockwise rolling path friction test on the outer wall of the test glass, realizing synchronous friction of the reciprocating rolling path. The test friction roller can be driven to perform bidirectional rolling friction through the up and down reciprocating movement of a single linkage bar. No additional power source is required to drive friction in different directions respectively, which simplifies the equipment structure, reduces costs, and at the same time improves the test efficiency and flexibility, and can more comprehensively simulate the friction conditions in actual usage scenarios.

[0028] In summary, through the mutual influence of the above-mentioned multiple effects, first, the linkage electric cylinder is linked through the same power source to make the linkage bar move back and forth up and down, so that the oblique arc friction block can move back and forth up and down along the outer wall of the test glass in an inclined arc path for friction, and at the same time, the vertical arc friction block can move back and forth up and down along the outer wall of the test glass in a vertical arc path for friction, and at the same time, the test friction roller performs a synchronous friction test on the outer wall of the test glass in a reciprocating rolling path. In summary, the same linkage electric cylinder power source is used to realize synchronous friction tests of the vertical arc, inclined arc and rotation path of the test glass, which not only has higher synchronous test efficiency, but also greatly reduces the production and use costs of the friction resistance test, and alleviates the economic burden of the friction resistance test.

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] As attached Figure 1 -Attached Figure 9 A glass panel friction resistance test device is shown, and the glass panel friction resistance test device is provided with an oblique arc synchronous friction test component, a vertical arc synchronous friction test component and a rolling path synchronous friction test component. The setting of each component can use the same linkage electric cylinder 30 power source to realize vertical arc, inclined arc and rotation path synchronous friction test on the test glass 13, which not only makes the synchronous test more efficient, but also greatly reduces the production and use cost of the friction resistance test, and alleviates the economic burden of the friction resistance test. The specific structural settings of each component are as follows.

[0041] In this embodiment, as shown in the attached Figure 1 -Attached Figure 5 As shown, the lower surface of the linkage bar 2 is provided with an oblique arc synchronous friction test assembly. The oblique arc synchronous friction test assembly includes: an oblique rope 3, the top end of which is fixedly connected to the lower surface of the linkage bar 2, and the bottom end of the oblique rope 3 is fixedly connected to an oblique arc sleeve block 4. A linkage column 5, one end of which is fixedly connected to the outer wall of the oblique arc sleeve block 4, and the other end of the linkage column 5 is threadedly connected to a mounting sleeve 6, one side of which is fixedly installed an oblique arc friction block 7, and one side of the mounting sleeve 6 is provided with a vertical arc synchronous friction test assembly. The vertical arc synchronous friction test assembly includes: a vertical rope 8, located on one side of the oblique rope 3, the top end of the vertical rope 8 is fixedly connected to the lower surface of the linkage bar 2, and the bottom end of the vertical rope 8 is fixedly connected to a vertical sleeve 9.

[0042] One end of the vertical column 10 is fixed on the outer wall of the vertical sleeve 9, and the other end of the vertical column 10 is threadedly connected to the mounting block 11. A vertical arc friction block 12 is fixedly installed on one side of the mounting block 11, and a test glass 13 is connected to one side of the vertical arc friction block 12. A rolling path synchronous friction test assembly is installed at one end of the linkage bar 2. The oblique arc friction block 7 is in contact with the test glass 13. The oblique arc friction block 7 and the vertical arc friction block 12 are both made of polyester fiber cloth, so that the linkage bar 2 drives the top end of the oblique rope 3 to move upward, and the oblique arc sleeve block 4 simultaneously drives the linkage column 5 to move upward in an arc path in the inclined direction, and the installation sleeve 6 drives the oblique arc friction block 7 to move upward in an arc path in the inclined direction. When the linkage bar 2 moves downward, the oblique arc sleeve block 4 drives the linkage column 5 to move downward in an arc path in the inclined direction under the action of the counterweight force, and the oblique arc friction block 7 moves downward along the outer wall of the test glass 13 along the arc path in the inclined direction. As the linkage bar 2 continues to move back and forth up and down, the oblique arc friction block 7 moves back and forth up and down along the outer wall of the test glass 13 along the arc path in the inclined direction and rubs. During the vertical arc synchronous friction test, the linkage bar 2 moves upward, driving the top of the vertical rope 8 to move upward synchronously. The vertical sleeve 9 then drives the vertical column 10 to move upward in a vertical arc path. Simultaneously, the mounting block 11 drives the vertical arc friction block 12 to move upward and rub along the vertical arc path of the outer wall of the test glass 13. When the linkage bar 2 moves downward, under the action of the counterweight force, the vertical sleeve 9 drives the vertical column 10 to move downward in a vertical arc path. The mounting block 11 drives the vertical arc friction block 12 to move downward and rub along the vertical arc path of the outer wall of the test glass 13. The linkage bar 2 continuously moves up and down, causing the vertical arc friction block 12 to move back and forth and rub along the vertical arc path of the outer wall of the test glass 13, achieving a synchronous friction resistance test.

[0043] In this embodiment, as shown in the attached Figure 6 - Attachment Figure 7As shown, the rolling path synchronous friction test assembly includes: a rack 26 fixedly connected to one end of the linkage bar 2, with a gear 27 meshingly connected to one side of the rack 26; a rotating rod 28 coaxially fixed to the inner wall of the gear 27, and rotatably connected to the guide cover 1. A test friction roller 29 is fixedly mounted on the outer wall of the rotating rod 28, and the outer wall of the test friction roller 29 is in contact with the test glass 13. The rack 26 is slidably connected to the guide cover 1, and the gear 27 rotates on the guide cover 1. When the linkage bar 2 moves upward, the rack 26 moves upward, causing the gear 27 and the rotating rod 28 to rotate clockwise, and the test friction roller 29 performs a clockwise rolling path friction test on the outer wall of the test glass 13. When the linkage bar 2 moves downward, the rack 26 moves downward synchronously, causing the gear 27 and the rotating rod 28 to rotate counterclockwise, and the test friction roller 29 performs a counterclockwise rolling path friction test on the outer wall of the test glass 13. By the up and down reciprocating movement of the linkage bar 2, the forward and reverse rolling friction of the test friction roller 29 can be achieved, which is easy to operate and can efficiently complete the reciprocating friction test on the outer wall of the test glass.

[0044] In this embodiment, as shown in the attached Figure 2 - Attachment Figure 5 As shown, the inner wall of the oblique arc sleeve block 4 is slidably connected with an oblique arc guide rail 17, and the outer wall of the oblique arc sleeve block 4 is fixedly connected with a counterweight oblique block 18 at a position adjacent to the linkage column 5; a support block 19 is fixedly installed on the top of the oblique arc guide rail 17, and the support block 19 is fixedly connected to the guide cover 1, and an oblique ring 20 is fixedly installed on one side of the support block 19, and the interior of the oblique ring 20 is slidably connected to the outer wall of the oblique rope 3; an oblique arc groove 21 is provided on the outside of the linkage column 5, and the linkage column 5 is slidably connected to the oblique arc groove 21, so that the oblique rope 3 is guided upward along the inner wall of the oblique ring 20, and the oblique arc sleeve block 4 moves upward in an arc path in an oblique direction along the outer wall of the oblique arc guide rail 17, so that the oblique arc sleeve block 4 drives the counterweight oblique block 18 to move upward in an arc path in an oblique direction, and the linkage column 5 moves upward in an arc path in an oblique direction inside the oblique arc groove 21, and moves stably according to the specified path guidance.

[0045] In this embodiment, as shown in the attached Figure 2 - Attachment Figure 5As shown, the outer wall of the vertical sleeve 9 is fixedly connected with a counterweight 22 at a position adjacent to the vertical column 10, and the inner wall of the vertical sleeve 9 is slidably connected with a vertical arc track 23. An arc groove 24 is provided on the outside of the vertical arc track 23, and the arc groove 24 is slidably connected to the vertical arc track 23. The top and bottom ends of the vertical arc track 23 are fixedly connected to the guide cover 1, and a positioning ring 25 is fixedly connected to the outer wall of the vertical arc track 23 near the linkage bar 2. The inner wall of the positioning ring 25 is slidably connected to the outer wall of the vertical rope 8, so that the vertical rope 8 moves up along the inner wall of the positioning ring 25, and the positioning vertical rope 8 is guided to move. At the same time, the vertical sleeve 9 moves up along the outer wall of the vertical arc track 23 in an arc path in the vertical direction, and the counterweight 22 moves up along the inside of the arc groove 24 in an arc path in the vertical direction, and is guided to move according to the specified path, thereby improving the stability of the vertical arc friction block 12 during movement.

[0046] In this embodiment, as shown in the attached Figure 8 - Attachment Figure 9 As shown, a positioning seat 31 is inserted into the outer wall of the test glass 13. A controller 15 is mounted on one side of the positioning seat 31. A guide post 14 is mounted above the controller 15 and is fixedly connected to the outer wall of the guide cover 1. A pressure sensor 16 is mounted above the guide post 14 and is fixedly connected to the guide cover 1. An extrusion cylinder 32 is mounted on the sensing end of the pressure sensor 16. The extrusion cylinder 32 is fixedly connected to the positioning seat 31, and the output end of the extrusion cylinder 32 is slidably connected to the positioning seat 31. The extrusion cylinder 32 is used to push the pressure sensor 16 to squeeze the guide cover 1. A linkage cylinder 30 is mounted on one side of the guide cover 1, and the output end of the linkage cylinder 30 is fixedly connected to the linkage bar 2. The outer wall of the guide post 14 is smooth, and a gap is provided between the guide post 14 and the pressure sensor 16. The pressure sensor 16 is electrically connected to the controller 15, and the extrusion electric cylinder 32 and the linkage electric cylinder 30 are both electrically connected to the controller 15, so that the test glass 13 can be inserted into the inner wall groove of the positioning seat 31 for positioning. The output end of the extrusion electric cylinder 32 moves along the inside of the positioning seat 31, and the output end of the extrusion electric cylinder 32 pushes the sensing end of the pressure sensor 16, and the guide cover 1 is squeezed on the outer wall of the test glass 13. When the pressure value sensed by the pressure sensor 16 exceeds the pressure value set by the controller 15, the controller 15 closes the extrusion electric cylinder 32, so that the guide cover 1 can be moved to the specified position on the outer wall of the test glass 13 with constant force.

[0047] The working method of the glass panel friction resistance testing device of the present invention is as follows:

[0048] First, when the present invention is installed and docked, the positioning seat 31 is fixed to the test platform by bolts inserted into the holes below the positioning seat 31, and then the test glass 13 is inserted into the inner wall groove of the positioning seat 31 for positioning. Under the action of the large counterweight force of the test glass 13 itself, the test glass 13 is firmly positioned and installed inside the positioning seat 31.

[0049] Then, the controller 15 activates the extrusion cylinder 32. The output end of the extrusion cylinder 32 moves along the interior of the positioning seat 31. Simultaneously, the output end of the extrusion cylinder 32 pushes the sensing end of the pressure sensor 16, causing the pressure sensor 16 to press against the guide cover 1. The guide cover 1 presses against the outer wall of the test glass 13. Simultaneously, the guide cover 1 drives the guide column 14 to slide along the inner wall of the positioning seat 31. Simultaneously, the guide cover 1 drives the support block 19 to move. The support block 19 drives the bevel guide rail 17 to move. The bevel guide rail 17 drives the bevel sleeve block 4 to move. The bevel sleeve block 4 drives the linkage column 5 to move. The linkage column 5 drives the mounting sleeve 6 to move the bevel friction block 7. The bevel friction block 7 presses against the outer wall of the test glass 13. Simultaneously, the guide cover 1 drives the vertical arc track 23 to move. The vertical arc track 23 drives the vertical sleeve 9 to move. The vertical sleeve 9 moves the vertical column 10. The vertical column 10 drives the mounting block 11 to move. The mounting block 11 drives the vertical arc friction block 12 to press against the outer wall of the test glass 13. Simultaneously, guide housing 1 drives rotating rod 28, which in turn drives test friction roller 29. The outer surface of test friction roller 29 presses against the outer wall of test glass 13. When the sensing end of pressure sensor 16 is squeezed by the output end of extrusion cylinder 32, the displacement of the sensing end of pressure sensor 16 senses a pressure value. When the pressure value sensed by pressure sensor 16 exceeds the pressure value set by controller 15, controller 15 deactivates extrusion cylinder 32. This ensures that the oblique arc friction block 7, vertical arc friction block 12, and test friction roller 29 all press against the outer wall of test glass 13 at the specified pressure.

[0050] Secondly, when the present invention conducts the inclined arc synchronous friction test, the controller 15 is used to start the linkage electric cylinder 30 to move the linkage bar 2 upward, and the linkage bar 2 drives the inclined rope 3 to move upward, and the inclined rope 3 moves upward along the inner wall of the inclined ring 20. At the same time, the bottom end of the inclined rope 3 drives the inclined arc sleeve block 4 to move upward along the outer wall of the inclined arc guide rail 17 in an arc path in the inclined direction, and the inclined arc sleeve block 4 drives the counterweight inclined block 18 to move upward in an arc path in the inclined direction. The inclined arc sleeve block 4 simultaneously drives the linkage column 5 to move upward in an arc path in the inclined direction inside the inclined arc groove 21, and the linkage column 5 drives the installation sleeve 6 to move upward in an arc path in the inclined direction, and the installation sleeve 6 drives the inclined arc friction block 7 to move upward in an arc path in the inclined direction, and the inclined arc friction block 7 moves upward in an arc path in the inclined direction along the outer wall of the test glass 13.

[0051] Then the controller 15 starts the linkage electric cylinder 30 to drive the linkage bar 2 to move downward. Under the action of the counterweight oblique block 18, the oblique arc sleeve block 4, the linkage column 5 and the installation sleeve 6, the counterweight force is greater than the friction force between the oblique arc friction block 7 and the test glass 13. In this way, the oblique arc sleeve block 4 drives the bottom end of the oblique rope 3 to move downward in an arc path in the inclined direction, and the oblique arc sleeve block 4 moves downward in an arc path in the inclined direction along the outer wall of the oblique arc guide rail 17. The oblique arc sleeve block 4 drives the linkage column 5 to move downward in an arc path in the inclined direction. The linkage column 5 drives the installation sleeve 6 to move downward in an arc path in the inclined direction. The installation sleeve 6 drives the oblique arc friction block 7 to move downward in an arc path in the inclined direction. The oblique arc friction block 7 moves downward in an arc path in the inclined direction along the outer wall of the test glass 13 by friction. The linkage electric cylinder 30 continuously makes the linkage bar 2 move back and forth up and down, thereby making the oblique arc friction block 7 move back and forth up and down along the outer wall of the test glass 13 by friction.

[0052] At the same time, when the present invention conducts a vertical arc synchronous friction test, when the linkage bar 2 moves upward, it will drive the top end of the vertical rope 8 to move upward, and the vertical rope 8 will move upward along the inner wall of the positioning ring 25. At the same time, the bottom end of the vertical rope 8 drives the vertical sleeve 9 to move upward in an arc path in the vertical direction. The vertical sleeve 9 moves upward in an arc path in the vertical direction along the outer wall of the vertical arc track 23. At the same time, the counterweight block 22 moves upward in an arc path in the vertical direction along the inside of the arc groove 24. The vertical sleeve 9 drives the vertical column 10 to move upward in an arc path in the vertical direction. The vertical column 10 drives the mounting block 11 to move upward in an arc path in the vertical direction. The mounting block 11 drives the vertical arc friction block 12 to move upward in an arc path in the vertical direction. The vertical arc friction block 12 moves upward in an arc path in the vertical direction and rubs along the outer wall of the test glass 13.

[0053] When the linkage bar 2 moves downward, it moves downward in an arc path in the vertical direction under the action of the counterweight force of the vertical sleeve 9, the counterweight block 22, the vertical column 10 and the mounting block 11. At this time, the friction between the vertical arc friction block 12 and the test glass 13 due to the counterweight force causes the vertical sleeve 9 to drive the bottom end of the vertical arc track 23 to move downward in an arc path in the vertical direction, and the vertical sleeve 9 drives the counterweight block 22 to move downward in an arc path in the vertical direction. The vertical sleeve 9 moves downward in an arc path in the vertical direction along the outer wall of the vertical arc track 23. At the same time, the vertical sleeve 9 drives the vertical column 10 to move downward in an arc path in the vertical direction, the vertical column 10 drives the mounting block 11 to move downward in an arc path in the vertical direction, and the mounting block 11 drives the vertical arc friction block 12 to move downward in an arc path in the vertical direction. In this way, the vertical arc friction block 12 moves downward in an arc path in the vertical direction along the outer wall of the test glass 13 and rubs. When the linkage bar 2 continuously moves up and down, the vertical arc friction block 12 can move back and forth along the outer wall of the test glass 13 in an arc path in the vertical direction to rub.

[0054] At the same time, when the present invention performs a rolling path synchronous friction test, when the linkage bar 2 moves upward, it also drives the rack 26 upward, the rack 26 drives the gear 27 to rotate clockwise, the gear 27 drives the rotating rod 28 to rotate clockwise, the rotating rod 28 drives the test friction roller 29 to rotate clockwise, and the test friction roller 29 performs a clockwise rolling path friction test on the outer wall of the test glass 13. When the linkage bar 2 moves downward, it also drives the rack 26 downward synchronously, the rack 26 drives the gear 27 to rotate counterclockwise, the gear 27 drives the rotating rod 28 to rotate counterclockwise, the rotating rod 28 drives the test friction roller 29 to rotate counterclockwise, and the test friction roller 29 performs a counterclockwise rolling path friction test on the outer wall of the test glass 13. In this way, as the linkage bar 2 continues to reciprocate up and down, the test friction roller 29 performs a reciprocating rolling path synchronous friction test on the outer wall of the test glass 13.

[0055] Finally, when the present invention records the test status, after the friction test contact, the controller 15 starts the output end of the extrusion electric cylinder 32 to contract, and the extrusion electric cylinder 32 drives the pressure sensor 16 to move. The pressure sensor 16 drives the guide cover 1 to no longer squeeze and contact the outer wall of the test glass 13, so that the test glass 13 is taken out from the inside of the positioning seat 31, and the damage of the friction area of ​​the vertical arc friction block 12 on the outer wall of the test glass 13 is checked. The damage of the friction area of ​​the oblique arc friction block 7 on the outer wall of the test glass 13 can also be checked, as well as the damage of the friction area of ​​the test friction roller 29 on the outer wall of the test glass 13. If the above areas are all damaged by friction, the test glass 13 is in an unqualified state. If the above areas are not damaged, the test glass 13 is in a qualified state.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
