[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0043] like Figure 1-Figure 9As shown, the embodiment of the present invention provides a silicone reflective material wear resistance testing device, including a base 100, an experimental base 101 is arranged above the base 100, the experimental base 101 and the base 100 are connected by a plurality of legs 106, an isolation cover 200 is arranged at the upper end of the experimental base 101, the isolation cover 200 is connected to an opening and closing driving component for driving its height adjustment, a rotating column 402 is arranged in the middle position of the experimental base 101, the lower end of the rotating column 402 is connected to a rotating driving component for driving its rotation, a mounting turntable 400 is arranged at the upper end of the rotating column 402, and a silicone sample 415 is tested on the mounting turntable 400. The test component of the test can be used to rub or hit the surface of the silicone sample 415, so as to meet the actual test needs. The upper end of the experimental base 101 is provided with a plurality of positioning components for fixing the silicone sample 415. The upper end of the experimental base 101 is also provided with a reflective detection component corresponding to the positioning component. The reflective property of the surface of the silicone sample 415 is monitored in real time through the reflective detection component, so that it is convenient to record the time diagram of the grinding time and the amount of material wear. The test component and the reflective detection component are electrically connected to the operation terminal 107, so that the reflective data of the silicone sample 415 can be displayed in time. In the actual experiment, multiple groups of materials can be set, so as to complete the comparative experiment;

[0044] like Figure 2 As shown, the rotary drive member includes a transmission worm wheel 600 arranged at the lower end of the rotating column 402, one side of the transmission worm wheel 600 is meshed with a transmission worm 601, the transmission worm 601 is connected to a driving motor 602 for driving the rotation thereof, the driving motor 602 is fixed at the bottom of the experimental base 101, both ends of the transmission worm 601 are rotatably connected to a fixed block at the bottom of the experimental base 101, the transmission worm 601 is driven to rotate by the driving motor 602, and the transmission worm 601 matches the transmission worm wheel 600 to complete the driving of the rotating column 402;

[0045] like Figure 3-Figure 5 As shown, the reflective detection component includes an emitting bracket 421 and a receiving bracket 423 arranged above the positioning component, the emitting bracket 421 is provided with a light emitting head 420 for emitting light, and the receiving bracket 423 is provided with a light receiving head 424 for receiving light, the light emitting head 420 and the light receiving head 424 are at least two groups, one group is used to detect the silicone sample 415 at the worn position, and the other group is used to detect the silicone sample 415 at the unworn position. Here, only part of the silicone sample 415 is in a worn and knocked state, and the other group is used for blank control to eliminate the interference of environmental factors on the test. Although the polishing time of the surface of the silicone sample 415 increases, the signal reflected by the silicone sample 415 will be weakened, which indirectly reflects the degree of wear on the surface of the silicone sample 415;

[0046] like Figure 5 As shown, the positioning component includes a sample fixing platform 414 arranged at the upper end of the experimental base 101, and a card slot is provided at the upper end of the sample fixing platform 414 for storing the silicone sample 415. Sliding baffles 426 are slidably provided on both sides of the upper end of the sample fixing platform 414 to press down and restrain the two ends of the silicone sample 415. The slider at one end of the sliding baffle 426 is slidably matched with the positioning slot 425 on the side of the sample fixing platform 414. The cross-sections of the positioning slot 425 and the slider are T-shaped. A complex is fixedly provided in the middle of the side of the sample fixing platform 414. The reset block 428 is connected to the sliding baffle 426 via a reset spring 427. When installing the silicone sample 415, the sliding baffle 426 is pulled to both sides to expose the card slot completely, and the silicone sample 415 is placed in the card slot on the sample fixing table 414. Then, the sliding baffle 426 is released. Under the action of the reset spring 427, the sliding baffle 426 will move to the top of the silicone sample 415 to lock the position of the silicone sample 415. This quick installation method facilitates the installation and removal of the silicone sample 415.

[0047] The test component includes a grinding vertical rod 417 which is vertically slidably arranged on the mounting turntable 400, and a test mounting unit for mounting a test block 429 is arranged at the lower end of the grinding vertical rod 417, and an adjusting slider 433 is arranged on one side of the upper end of the grinding vertical rod 417, and an adjusting screw 431 is threadedly arranged on one side of the adjusting slider 433, and the lower end of the adjusting screw 431 is connected to an adjusting motor 430 for driving the adjusting screw 431 to rotate, and the upper end of the adjusting screw 431 is rotatably connected to an adjusting bracket 432 on the mounting turntable 400, and under the action of the adjusting motor 430, the adjusting screw 431 and the adjusting slider 433 rotate relative to each other, and under the action of the thread, the adjusting slider 433 slides up and down along the adjusting screw 431, so that the bottom height of the grinding vertical rod 417 can be adjusted, so as to adjust the friction pressure on the surface of the silicone sample 415;

[0048] like Figure 5-8 As shown, the test component also includes a floating column 406 that slides vertically on the mounting turntable 400, a floating side plate 404 is provided on one side of the floating column 406, and the floating side plate 404 is slidably set on a floating slide bar 405, and the floating slide bar 405 is fixedly connected to the upper end of the mounting turntable 400. A conical block 407 is rotatably provided on the outer side of the floating column 406, and a pushing mechanism for generating intermittent thrust on the conical block 407 is also provided on the mounting turntable 400. The floating column 406 is reciprocated up and down by the pushing mechanism, so that the impact head 502 at the lower end of the floating column 406 impacts the silica gel sample 415;

[0049] The test component and the reflective detection component are staggered, so there is no need to worry about interference. Although the grinding frame 416 will block the data acquisition of the light receiving head 424 for a short time when it rotates, it does not affect the subsequent information reception of the light receiving head 424.

[0050] The pushing mechanism includes a bearing frame 413 vertically fixed on the mounting turntable 400, a horizontal shaft 411 rotatably provided on the bearing frame 413 and extending toward the conical block 407, a transmission gear 412 is fixedly provided at the outer end of the horizontal shaft 411, the transmission gear 412 is meshed with the fixed gear ring 401, the fixed gear ring 401 is connected and fixed to the inner wall of the isolation cover 200 through a positioning cross bar, a fine-tuning sleeve 409 is slidably provided at one end of the horizontal shaft 411 toward the conical block 407, an elliptical block 408 that generates thrust for the conical block 407 is fixedly provided at the end of the fine-tuning sleeve 409, a rotation limiter is provided between the fine-tuning sleeve 409 and the horizontal shaft 411, a floating side plate 404 is also provided on the outer side of the floating column 406, the floating side plate 404 is slidably set on the floating slide bar 405, and the bottom of the floating slide bar 405 is fixed to the mounting The upper end of the turntable 400 is fixedly connected, and the floating slide bar 405 is connected to the installation turntable 400 through a floating spring 403. A push ring 435 is provided on the outer side of the fine-tuning sleeve 409 for rotation. The push ring is connected to the fine-tuning telescopic rod 410 for driving it to slide along the axis of the horizontal shaft 411. When the installation turntable 400 rotates, the transmission gear 412 matches with the fixed gear ring 401 and rotates. The transmission gear 412 drives the fine-tuning sleeve 409 and the elliptical block 408 to rotate. The push ring and the fine-tuning sleeve 409 are driven to move toward the conical block 407 through the fine-tuning telescopic rod 410. The rotation of the elliptical block 408 will generate intermittent thrust on the conical block 407. Since the conical block 407 is a conical structure, as the pushing amplitude of the elliptical block 408 increases, the pushing amplitude of the elliptical block 408 on the elliptical block 408 will change, so that the force of the bottom of the floating column 406 can be adjusted.

[0051] The rotation limiter comprises a limit protrusion 434 arranged on the surface of the horizontal shaft 411, and the inner wall of the fine-tuning sleeve 409 is provided with a limit groove matching the limit protrusion. The cooperation between the limit protrusion and the limit groove enables the fine-tuning sleeve 409 and the horizontal shaft 411 to only slide relative to each other, but not to rotate relative to each other.

[0052] The test installation unit includes a grinding frame 416 arranged at the lower end of the grinding vertical rod 417 or the floating column 406, and a grinding installation groove 418 is opened at the upper end of the grinding frame 416, and the grinding installation groove 418 matches the silicone sample 415. The test block 429 includes a mounting block 500 matching the grinding installation groove 418, and a grinding head 501 for rubbing the surface of the silicone sample 415 or an impact head 502 for knocking the surface of the silicone sample 415 is provided at the lower end of the mounting block 500. A rotating baffle 419 is rotatably provided on one side of the upper end of the grinding frame 416. By rotating the rotating baffle 419, the test block 429 can be restricted in the grinding installation groove 418, thereby completing quick installation. This installation method is also convenient for later replacement;

[0053] A test block 429 with a striking head 502 is installed at a position where striking is applied, and a test block 429 with a grinding head 501 is installed at a position where friction is applied;

[0054] The upper end of the isolation cover 200 is provided with a temperature regulating component for regulating the internal experimental temperature of the experimental base 101. After all, the wear resistance of the material is different under different temperature conditions. The temperature regulating component includes a heat exchange box 300 arranged at the upper end of the isolation cover 200. The heat exchange box 300 is provided with a heating pipe group for heating. The exhaust end of the heat exchange box 300 is connected to the circulation fan 302, and the exhaust end of the circulation fan 302 is connected to the air intake buffer box 301. The air intake end of the heat exchange box 300 is connected to the exhaust buffer box 304 through the return air pipe 303. The upper end of the isolation cover 200 where the exhaust buffer box 304 and the air intake buffer box 301 are located is provided with a plurality of connecting holes. In this way, the hot air in the heat exchange box 300 can be sent into the air intake buffer box 301 through the circulation fan 302, and the air flow enters the isolation cover 200 through the connecting holes, so that the test material is in the target environment. After all, the flexibility of the material is different at different temperatures, which makes the test more accurate.

[0055] The opening and closing driving component includes a mounting seat 105 arranged on one side of the experimental base 101, and the mounting seat 105 is connected to the bottom of the experimental base 101 through a reinforcing rod. Two lifting guide rods 103 are symmetrically arranged on the upper end of the mounting seat 105, and the tops of the two lifting guide rods 103 are connected by a horizontal plate. A threaded block is slidably arranged on the lifting guide rod 103, and the threaded block is connected to the side of the isolation cover 200 through a connecting rod. A lifting motor 104 is arranged on the upper end of the mounting seat 105, and a lifting screw 102 is arranged at the output end of the lifting motor 104. The upper end of the lifting screw 102 is rotatably connected to the horizontal plate, and the lifting screw 102 is threadedly connected to the threaded block. Under the action of the lifting motor 104, the lifting screw 102 and the threaded block rotate relatively. Under the action of the thread, the connecting rod and the threaded block drive the isolation cover 200 to adjust the height, so that the upper end of the experimental base 101 is in an operable or closed state:

[0056] The isolation cover 200 here can be made of a transparent material so as to observe the polishing status inside it;

[0057] Working principle: In actual use, the isolation cover 200 is first raised by opening and closing the driving component, and then the test material is tested into a predetermined size as required, and then the silicone sample 415 is fixed by the positioning component;

[0058] When installing the silicone sample 415, pull the sliding baffle 426 to both sides to expose the card slot completely, put the silicone sample 415 into the card slot on the sample fixing table 414, and then release the sliding baffle 426. Under the action of the return spring 427, the sliding baffle 426 will move to the top of the silicone sample 415 to lock the position of the silicone sample 415. This quick installation method facilitates the installation and removal of the silicone sample 415.

[0059] Then, the corresponding test block 429 is installed. After the installation is completed, the friction pressure on the silicone sample 415 is adjusted as needed. Under the action of the adjustment motor 430, the adjustment screw 431 and the adjustment slider 433 rotate relatively. Under the action of the thread, the adjustment slider 433 slides up and down along the adjustment screw 431, so that the bottom height of the grinding vertical rod 417 can be adjusted to adjust the friction pressure on the surface of the silicone sample 415.

[0060] By adjusting the positions of the light emitting head 420 and the light receiving head 424, the reflective data of the silicone sample 415 is detected, and then the mounting turntable 400 is driven to rotate by the rotating driving component. During the rotation of the mounting turntable 400, the grinding frame 416 at the lower end of the floating column 406 rotates, thereby rubbing the upper end surface of the silicone sample 415;

[0061] The floating column 406 can also be made to reciprocate up and down through the pushing mechanism, so that the impact head 502 at the lower end of the floating column 406 impacts the silicone sample 415. During the entire test process, the light receiving head 424 will obtain two sets of data on the surface of the silicone sample 415, one set is the test part, and the other set is the blank part. The data is then displayed through the operation terminal 107, so that the staff can always grasp the loss of materials. When conducting the test, the test temperature can also be adjusted so that the sample can be tested under different environments.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
