Description
Technical Field
[0001] This application relates to the field of abrasion resistance testing instruments, and more particularly to a coating abrasion resistance testing instrument. Background Technology
[0002] Abrasion resistance is a crucial indicator for evaluating the durability and practicality of coatings, which are widely used in industries such as construction, automotive, shipbuilding, and furniture. With industrial development and increasingly stringent environmental requirements, the abrasion resistance of coatings is receiving increasing attention.
[0003] Currently, traditional coating wear resistance testers use a basic test structure where a motor drives a friction head to contact the workpiece. However, the friction pressure adjustment relies on a manual knob or a simple mechanical structure. Traditional coating wear resistance testers cannot quickly adjust the pressure. When the friction head wears down during the test, the pressure cannot be adjusted in real time, requiring manual interruption for calibration. This results in insufficient test accuracy and low reliability of the results. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides a coating abrasion resistance tester, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.
[0005] To achieve the above objectives, this application adopts the following technical solution: a coating abrasion resistance tester, comprising a base, a clamping assembly inside the base, a height adjustment assembly on the top of the base, a moving rod on one side of the height adjustment assembly, a fixed block slidably connected inside the moving rod, a moving assembly on one side of the fixed block, a detection assembly inside the fixed block, the detection assembly including an electric push rod, the electric push rod being fixedly connected to the fixed block, a moving block being fixedly connected to the telescopic end of the electric push rod, a pressure sensor being fixedly connected inside the moving block, an insertion block on one side of the pressure sensor, the insertion block being slidably connected to the moving block, a friction head slidably connected inside the insertion block, two positioning rods slidably connected inside the friction head, the two positioning rods being symmetrically distributed inside the friction head, and a spring being provided between the two positioning rods.
[0006] In a preferred embodiment, a limiting hole is formed on the surface of the insert block, and the limiting hole is adapted to the positioning rod.
[0007] By adopting the above technical solution, a limiting hole is opened on the surface of the insert block, and the positioning rod is limited by the limiting hole, which facilitates the insertion of the positioning rod into the interior of the insert block and can better limit the positioning rod.
[0008] In a preferred embodiment, a controller is fixedly connected to the surface of the base, and the electric push rod and pressure sensor are both electrically connected to the controller.
[0009] By adopting the above technical solution, a controller is fixedly connected to the surface of the base, and the pressure sensor transmits the pressure data between the friction head and the sample to the controller in real time. The controller then analyzes and processes the data. If there is a deviation between the actual pressure and the set pressure, the controller will activate the electric push rod, which can better monitor the pressure data between the friction head and the sample.
[0010] In a preferred embodiment, the clamping assembly includes a motor, which is fixedly connected to a base. A threaded rod is fixedly connected to the output end of the motor, and a threaded rod is fixedly connected to one side of the threaded rod. The threaded rod is opposite in direction to the threaded rod. Both the threaded rod and the threaded rod are rotatably connected to the base. Clamping plates are threadedly connected to the surfaces of both the threaded rod and the threaded rod. The clamping plates are slidably connected to the base, and a slider is fixedly connected to the surface of the clamping plates. A groove is formed on the surface of the base, and the groove is adapted to the slider.
[0011] By adopting the above technical solution, the sample is placed on the surface of the base, and the motor is started. Its output end drives the threaded rod 2 and the threaded rod 1 to rotate. Under the action of threaded transmission, the clamping plates will move towards each other or away from each other because the threads are opposite. Then, the slider fixed on the surface of the clamping plate slides in the groove opened on the surface of the base, which guides and limits the movement of the clamping plate and prevents the clamping plate from deflecting during the movement. This realizes the clamping or loosening of coating samples of different sizes, and can better clamp and fix coating samples of different sizes.
[0012] In a preferred embodiment, the height adjustment assembly includes a limiting rod, which is fixedly connected to the base. A second motor is fixedly connected to the top of the limiting rod, and a third threaded rod is fixedly connected to the output end of the second motor. The third threaded rod is rotatably connected to the limiting rod, and a movable rod is threadedly connected to the surface of the third threaded rod. The movable rod is slidably connected to the limiting rod.
[0013] By adopting the above technical solution, the limiting rod is fixedly connected to the base, which plays a supporting and guiding role. Then, the starting motor 2 drives the threaded rod 3 to rotate from its output end. Since the threaded rod 3 is threadedly connected to the moving rod, and the moving rod is slidably connected to the limiting rod, under the guidance of the threaded transmission and the limiting rod, the moving rod moves vertically along the limiting rod, thereby driving the fixed block and the detection component to move vertically. This allows the moving rod to move vertically within the limiting rod more effectively.
[0014] In a preferred embodiment, the moving component includes a motor three, which is fixedly connected to a moving rod. A drive gear is fixedly connected to the output end of the motor three. A rack meshes with one side of the drive gear. The rack is fixedly connected to a fixed block and slidably connected to the moving rod.
[0015] By adopting the above technical solution, starting motor three drives the drive gear to rotate at its output end. The drive gear meshes with the rack. Under the action of gear transmission, the rotation of the drive gear is converted into the linear movement of the rack along the moving rod, so that the fixed block slides inside the moving rod, which can better enable the fixed block to slide inside the moving rod.
[0016] In a preferred embodiment, an anti-slip pad is fixedly connected to the surface of the clamping plate, and the anti-slip pad is a rubber component.
[0017] By adopting the above technical solution, a rubber anti-slip pad is fixed on the surface of the clamping plate. When the clamping assembly clamps the coating sample, the rubber material has a large coefficient of friction, which can increase the friction between the anti-slip pad and the sample. At the same time, the elasticity of the rubber can make the anti-slip pad fit better with the sample surface, further enhancing the friction and preventing the sample from sliding due to vibration or friction during the test. This can better prevent the sample from sliding during the test.
[0018] The beneficial effects of this application are: 1. This coating abrasion resistance tester comprises a friction head, positioning rods, springs, insert blocks, pressure sensors, moving blocks, and electric push rods. The electric push rods push the moving blocks, causing the friction head to approach the sample surface. The pressure sensor monitors the pressure between the friction head and the sample in real time, ensuring the test pressure meets the set requirements. The friction head then rubs against the sample surface to complete the coating abrasion resistance test. The friction head and insert blocks are slidably connected for easy assembly and disassembly. During assembly, the spring force pushes two positioning rods into the insert blocks to connect them. During disassembly, pressing the positioning rods retracts them into the friction head, and pulling the friction head completes the disassembly. This design avoids the problem of traditional coating abrasion resistance testers being unable to quickly adjust the pressure in real time, thus improving practicality.
[0019] 2. This coating abrasion resistance tester comprises a slider, a motor, a clamping plate, a threaded rod, and a threaded rod. By placing the sample on the base surface and activating the motor, the output of the motor drives the threaded rods to rotate. Under the action of the threaded transmission, the clamping plates move towards or away from each other due to the opposite thread direction. The slider fixed to the surface of the clamping plate slides into a groove on the base surface, guiding and limiting the movement of the clamping plate, preventing deflection during movement. This allows for the clamping or releasing of coating samples of different sizes, avoiding the need for manual sample fixing required in traditional coating abrasion resistance testers, thus improving practicality.

Detailed Implementation
[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0023] Reference Figures 1-6A coating abrasion resistance tester includes a base 1, a clamping assembly 2 inside the base 1, a height adjustment assembly 3 on the top of the base 1, a moving rod 6 on one side of the height adjustment assembly 3, a fixed block 7 slidably connected inside the moving rod 6, a moving assembly 4 on one side of the fixed block 7, a detection assembly 5 inside the fixed block 7, the detection assembly 5 including an electric push rod 57, the electric push rod 57 being fixedly connected to the fixed block 7, a moving block 56 being fixedly connected to the telescopic end of the electric push rod 57, a pressure sensor 55 being fixedly connected inside the moving block 56, an insertion block 54 on one side of the pressure sensor 55, the insertion block 54 being slidably connected to the moving block 56, a friction head 51 being slidably connected inside the insertion block 54, two positioning rods 52 being slidably connected inside the friction head 51, the two positioning rods 52 being symmetrically distributed inside the friction head 51, and a spring 53 being provided between the two positioning rods 52.
[0024] Reference Figures 4-6 The surface of the insert block 54 is provided with a limiting hole, which is adapted to the positioning rod 52. By providing a limiting hole on the surface of the insert block 54, the positioning rod 52 is limited, which facilitates the insertion of the positioning rod 52 into the interior of the insert block 54 and allows for better positioning of the positioning rod 52.
[0025] Reference Figures 2-6 A controller 8 is fixedly connected to the surface of the base 1. The electric push rod 57 and the pressure sensor 55 are both electrically connected to the controller 8. The controller 8 is fixedly connected to the surface of the base 1, and the pressure sensor 55 transmits the pressure data between the friction head 51 and the sample to the controller 8 in real time. The controller 8 then analyzes and processes the data. If there is a deviation between the actual pressure and the set pressure, the controller 8 will activate the electric push rod 57 to better monitor the pressure data between the friction head 51 and the sample.
[0026] Reference Figures 1-3The clamping assembly 2 includes a motor 22, which is fixedly connected to the base 1. A threaded rod 24 is fixedly connected to the output end of the motor 22. A threaded rod 25 is fixedly connected to one side of the threaded rod 24. The thread direction of the threaded rod 25 is opposite to that of the threaded rod 24. Both the threaded rod 25 and the threaded rod 24 are rotatably connected to the base 1. A clamping plate 23 is threadedly connected to the surfaces of both the threaded rod 25 and the threaded rod 24. The clamping plate 23 is slidably connected to the base 1. A slider 21 is fixedly connected to the surface of the clamping plate 23. A groove is formed on the surface of the base 1, and the groove is adapted to the slider 21. By placing the sample on the surface of the base 1 and starting the motor 22, the output end of the motor drives the threaded rod 25 and the threaded rod 24 to rotate. Under the action of threaded transmission, the clamping plates 23 will move towards each other or away from each other due to the opposite direction of the threads. The slider 21 fixed on the surface of the clamping plate 23 slides and engages with the groove on the surface of the base 1, which guides and limits the movement of the clamping plate 23 and prevents the clamping plate 23 from deflecting during the movement. This allows for the clamping or loosening of coating samples of different sizes, and can better clamp and fix coating samples of different sizes.
[0027] Reference Figure 4 The height adjustment component 3 includes a limiting rod 32, which is fixedly connected to the base 1. A second motor 31 is fixedly connected to the top of the limiting rod 32. A threaded rod 33 is fixedly connected to the output end of the second motor 31. The threaded rod 33 is rotatably connected to the limiting rod 32. A moving rod 6 is threadedly connected to the surface of the threaded rod 33. The moving rod 6 is slidably connected to the limiting rod 32. The limiting rod 32 is fixedly connected to the base 1, which provides support and guidance. The second motor 31 is started, and its output end drives the threaded rod 33 to rotate. Since the threaded rod 33 is threadedly connected to the moving rod 6, and the moving rod 6 is slidably connected to the limiting rod 32, under the guidance of the threaded transmission and the limiting rod 32, the moving rod 6 moves linearly up and down along the limiting rod 32, thereby driving the fixed block 7 and the detection component 5 to move up and down. This allows the moving rod 6 to move linearly up and down inside the limiting rod 32 more effectively.
[0028] Reference Figures 4-5 The moving component 4 includes a motor 41, which is fixedly connected to the moving rod 6. A drive gear 42 is fixedly connected to the output end of the motor 41. A rack 43 meshes with one side of the drive gear 42. The rack 43 is fixedly connected to the fixed block 7 and slidably connected to the moving rod 6. By starting the motor 41, its output end drives the drive gear 42 to rotate. The drive gear 42 meshes with the rack 43. Under the action of gear transmission, the rotation of the drive gear 42 is converted into the linear movement of the rack 43 along the moving rod 6, so that the fixed block 7 slides inside the moving rod 6, which can better enable the fixed block 7 to slide inside the moving rod 6.
[0029] Reference Figures 1-3 An anti-slip pad 9 is fixedly connected to the surface of the clamping plate 23. The anti-slip pad 9 is a rubber component. By fixing the rubber anti-slip pad 9 to the surface of the clamping plate 23, when the clamping assembly 2 clamps the coating sample, the rubber material has a large coefficient of friction, which can increase the friction between the anti-slip pad 9 and the sample. At the same time, the elasticity of the rubber can make the anti-slip pad 9 fit better with the sample surface, further enhancing the friction and preventing the sample from sliding due to vibration or friction during the test. This can better prevent the sample from sliding during the test.
[0030] Working principle: By placing the sample on the surface of the base 1, the motor 22 is started, and its output end drives the threaded rod 25 and the threaded rod 24 to rotate. Under the action of threaded transmission, the clamping plates 23 will move towards or away from each other due to the opposite thread direction. The slider 21 fixed on the surface of the clamping plate 23 slides with the groove on the surface of the base 1, which guides and limits the movement of the clamping plate 23, preventing the clamping plate 23 from deflecting during the movement, thus achieving clamping or loosening of coating samples of different sizes. The limiting rod 32 is fixedly connected to the base 1, which provides support and guidance. The motor 31 is then started, and its output end drives the threaded rod 33 to rotate. Since the threaded rod 33 is threadedly connected to the moving rod 6, and the moving rod 6 is slidably connected to the limiting rod 32, under the guidance of the threaded transmission and the limiting rod 32, the moving rod 6 moves linearly up and down along the limiting rod 32, thereby driving the fixed block 7 and the detection component 5 to move up and down. The motor 21 is then started, and its output end drives the threaded rod 33 to rotate. The push rod 57 pushes the moving block 56, causing the friction head 51 to approach the sample surface. After the friction head 51 contacts the sample surface, the insert block 54 contacts the pressure sensor 55. The pressure sensor 55 monitors the pressure between the friction head 51 and the sample in real time to ensure that the test pressure meets the set requirements. Then, the starter motor 41 drives the drive gear 42 to rotate. The drive gear 42 meshes with the rack 43. Under the action of gear transmission, the rotation of the drive gear 42 is converted into the linear movement of the rack 43 along the moving rod 6, causing the fixed block 7 to slide inside the moving rod 6. Then, the fixed block 7 moves and drives the friction head 51 to slide on the sample surface. Subsequently, the friction head 51 rubs against the sample surface to complete the coating wear resistance test. The friction head 51 and the insert block 54 are slidably connected for easy disassembly and assembly. During installation, the spring 53 pushes the two positioning rods 52 into the insert block 54 to connect them. During disassembly, press the positioning rods 52 to retract them into the friction head 51, and pull the friction head 51 to complete the disassembly.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
