Description

Technical Field

[0001] This utility model belongs to the field of material surface testing technology, and in particular relates to a surface performance testing device for new material research and development. Background Technology

[0002] In the process of new material research and development, the surface properties of materials are often the key to the success or failure of their final application. Among them, scratch resistance and surface durability are one of the core indicators for evaluating the reliability of materials in actual use environments. Whether it is a protective coating for consumer electronics products, a clear coat for automobiles, or a protective film in the aerospace field, the ability of a material surface to resist scratches, wear, and even cracks directly affects the appearance, functional lifespan, and safety of the product.

[0003] Chinese patent CN208833612U discloses a new material surface scratch detection platform, including a base, a new material positioning device, a reciprocating scratch device, and a reduction motor; the new material positioning device is provided at the upper end of the base; the reciprocating scratch device is provided at the right end of the new material positioning device; and the reduction motor is provided at the rear end of the reciprocating scratch device.

[0004] As shown above, this device uses intermittent gears, and the motor only needs to rotate in the same direction. It can perform scratching in both reciprocating and non-reciprocating directions, resulting in high scratching efficiency. The new material positioning device can be replaced according to the thickness of the new material to ensure scratching pressure. However, this device requires the material to be manually placed on the positioning plate, and then the clamping plate is pressed together by hand-tightening screws to fix the material. However, it is cumbersome to tighten the screws by hand to fix the material each time, which will reduce the efficiency of testing and increase the labor intensity of the operator. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a surface performance testing device for new material research and development, which solves the problem of low testing efficiency.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a surface performance testing device for new material research and development, comprising a frame, a fixing plate fixedly connected to the outer wall of the frame, a clamping mechanism provided on the frame, and a scratching mechanism provided on the fixing plate; The clamping mechanism includes a sliding groove inside the frame, two clamping plates slidably connected to the inner wall of the sliding groove, a guide groove inside the frame, a guide shaft fixedly connected to the outer wall of the frame, a bidirectional lead screw threaded to the inner wall of the two clamping plates, a worm gear fixedly connected to the outer wall of the bidirectional lead screw, and a worm engaging with the outer wall of the worm gear.

[0007] Preferably, the inner wall of the guide groove is slidably connected to the outer walls of the two clamping plates, the outer wall of the guide shaft is slidably connected to the inner walls of the two clamping plates, and the outer wall of the bidirectional lead screw is rotatably connected to the inner wall of the frame.

[0008] Preferably, the scratching mechanism includes two fixed shafts fixedly connected to the inner wall of the fixed plate, a movable block slidably connected to the outer wall of the two fixed shafts, and a hydraulic device fixedly connected to the top of the movable block.

[0009] Preferably, a hydraulic rod is fixedly connected to the output end of the hydraulic device, the outer wall of the hydraulic rod is slidably connected to the inner wall of the moving block, an mounting plate is fixedly connected to the bottom of the hydraulic rod, and a disassembly plate is connected to the inner wall of the mounting plate by screws.

[0010] Preferably, a pressure head is fixedly connected to the bottom of the disassembly plate, a support plate is fixedly connected to the outer wall of the fixing plate, a motor is fixedly connected to the top of the support plate, and a rotating shaft is fixedly connected to the output shaft of the motor via a coupling.

[0011] Preferably, a rotating shaft is fixedly connected to the bottom of the rotating shaft, a connecting rod is rotatably connected to the outer wall of the rotating shaft, a fixed rod is rotatably connected to the end of the connecting rod away from the rotating shaft, and the fixed rod is fixedly connected to the inner wall of the fixed plate.

[0012] This utility model has the following beneficial effects: 1. The surface performance testing equipment for the research and development of this new material uses manual rotation of the worm gear to drive the worm wheel and drive the bidirectional lead screw connected to it to rotate, thereby controlling the two clamping plates to move closer to each other and achieving stable clamping of the material. In this process, the cooperation between the guide groove and the guide shaft effectively ensures the accuracy of the movement direction of the clamping plates and prevents them from deviating or getting stuck during movement.

[0013] 2. The surface performance testing equipment for this new material research and development uses an external controller to start a hydraulic system, which controls the hydraulic rod to move downwards, thereby moving the mounting plate, disassembly plate, and pressure head downwards. This brings the pressure head close to the material surface and applies pressure. Subsequently, the external controller starts a motor, which drives the rotating shaft to rotate, thereby driving the rotating shaft to revolve. This causes the connecting rod to move regularly, pulling the fixed rod and moving block to reciprocate on the fixed shaft. This allows the pressure head to move regularly on the material surface to generate scratches. Finally, the material is removed and sent to external equipment for testing, which can effectively verify whether the surface scratch resistance of the material is up to standard.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides two technical solutions: Figures 1-3 The first embodiment of the surface performance testing equipment for new material research and development is shown: The surface performance testing equipment for new material research and development includes a frame 1, a fixing plate 101 fixedly connected to the outer wall of the frame 1, a clamping mechanism 2 provided on the frame 1, and a scratching mechanism 3 provided on the fixing plate 101. The clamping mechanism 2 includes a slide groove 207 inside the frame 1. Two clamping plates 201 are slidably connected to the inner wall of the slide groove 207. A guide groove 202 is provided inside the frame 1. A guide shaft 203 is fixedly connected to the outer wall of the frame 1. A two-way screw 204 is threadedly connected to the inner wall of the two clamping plates 201. A worm gear 205 is fixedly connected to the outer wall of the two-way screw 204. A worm 206 is meshed with the outer wall of the worm gear 205. Manually rotate the worm gear 206 to drive the worm wheel 205 and the connected bidirectional lead screw 204 to rotate, thereby controlling the two clamping plates 201 to move closer to each other and achieve stable clamping of the material.

[0020] The inner wall of the guide groove 202 is slidably connected to the outer wall of the two clamping plates 201, the outer wall of the guide shaft 203 is slidably connected to the inner wall of the two clamping plates 201, and the outer wall of the bidirectional screw 204 is rotatably connected to the inner wall of the frame 1. During the process of the two clamping plates 201 approaching each other, the cooperation between the guide groove 202 and the guide shaft 203 effectively ensures the accuracy of the moving direction of the clamping plate 201 and prevents it from deviating or getting stuck during the movement.

[0021] First, place the material between the two clamping plates 201. Then, manually rotate the worm gear 206 to drive the worm wheel 205 to rotate. When the worm wheel 205 rotates, it will drive the double-acting screw 204 to rotate, thereby bringing the two clamping plates 201 closer together to clamp the material. While the two clamping plates 201 are moving, the guide groove 202 and the guide shaft 203 will guide them to prevent deviations during the movement.

[0022] Figures 4-6 The second embodiment is shown. The main difference between this embodiment and the first embodiment of the surface performance testing equipment for new material research and development is that the scratching mechanism 3 includes two fixed shafts 301 fixedly connected to the inner wall of the fixed plate 101. A moving block 302 is slidably connected to the outer wall of the two fixed shafts 301. A hydraulic device 303 is fixedly connected to the top of the moving block 302. A hydraulic rod 304 is fixedly connected to the output end of the hydraulic device 303. The outer wall of the hydraulic rod 304 is slidably connected to the inner wall of the moving block 302. An installation plate 305 is fixedly connected to the bottom of the hydraulic rod 304. A disassembly plate 306 is connected to the inner wall of the installation plate 305 by screws. A pressure head 307 is fixedly connected to the bottom of the disassembly plate 306. A support plate 308 is fixedly connected to the outer wall of the fixed plate 101. A motor 309 is fixedly connected to the top of the support plate 308. A rotating shaft 310 is fixedly connected to the output shaft of the motor 309 by a coupling. By starting the hydraulic unit 303 with an external controller, the hydraulic rod 304 can be moved downward, which in turn drives the mounting plate 305, the disassembly plate 306 and the pressure head 307 to move downward, so that the pressure head 307 is close to the material surface and applies pressure.

[0023] A rotating shaft 311 is fixedly connected to the bottom of the rotating shaft 310. A connecting rod 312 is rotatably connected to the outer wall of the rotating shaft 311. A fixed rod 313 is rotatably connected to the end of the connecting rod 312 away from the rotating shaft 311. The fixed rod 313 is fixedly connected to the inner wall of the fixed plate 101. The external controller starts the motor 309, which drives the rotating shaft 310 to rotate, and then drives the rotating shaft 311 to revolve, causing the connecting rod 312 to move regularly, pulling the fixed rod 313 and the moving block 302 to reciprocate on the fixed shaft 301, so that the pressure head 307 moves regularly on the material surface to produce scratches.

[0024] The hydraulic actuator 303 is activated by an external controller, which controls the hydraulic rod 304 to move downward, thereby moving the mounting plate 305. This, in turn, causes the disassembly plate 306 to move downward. As the disassembly plate 306 moves downward, it also moves the pressure head 307, bringing it close to the material surface and applying pressure. Then, the motor 309 is activated by the external controller, causing the rotating shaft 310 to rotate. As the rotating shaft 310 rotates, it causes the rotating shaft 311 to revolve, causing the connecting rod 312 to move rhythmically. As the connecting rod 312 moves, it pulls the fixed rod 313 to move as well, which in turn causes the moving block 302 to reciprocate rhythmically on the fixed shaft 301. This causes the pressure head 307 to move rhythmically on the material surface, creating scratches. The material is then removed and sent to external equipment for testing to ensure that the material's surface scratch resistance is up to standard.
