Detailed Implementation

[0052] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] Example 1

[0054] Please see Figure 1 - Figure 6 This application provides a carbon sliding plate friction and wear testing device, comprising:

[0055] A base 100, a carbon sliding plate body 103 is placed on the top of the base 100, and a reciprocating component 200 is provided on the upper surface of the base 100 to drive the friction wheel 104 to reciprocate and rub against the carbon sliding plate body 103.

[0056] Adjusting component 400 for adjusting the friction height of friction wheel 104 against carbon slide plate 103;

[0057] The pressure regulating mechanism 300, located behind the carbon slide plate 103 and cooperating with the reciprocating component 200, can perform constant pressure friction and wear tests on the surface of the carbon slide plate 103, and can also apply different pressure wear tests to the upper surface of the carbon slide plate 103 to simulate wear tests on the surface of the carbon slide plate 103 under different pressure fluctuation ranges. This improves the comprehensiveness of the wear test on the surface of the carbon slide plate 103 and provides more data references for the wear resistance of the carbon slide plate 103. The pressure regulating mechanism 300 includes an arc-shaped protrusion 305 installed on the rear surface of the adjusting component 400, a transverse pressure regulating component 301 that can move back and forth and cooperate with the moving plate 205, and a pressure detection component 303 that detects the downward pressure of the friction wheel 104 on the carbon slide plate 103.

[0058] In this embodiment, preferably, the reciprocating component 200 that drives the friction wheel 104 to reciprocate includes:

[0059] A fixing plate 201 is fixed to the upper surface of the base 100. A drive motor 202 is provided on the rear surface of the upper end of the fixing plate 201 to facilitate the rotation of the rotating wheel 203.

[0060] A rotating wheel 203 is installed at the front end of the output shaft of the drive motor 202. The rotating wheel 203 is located on the front surface of the fixed plate 201. Two uprights 102 are provided on the upper surface of the base 100. A front plate 105 is provided on the front surface of the uprights 102.

[0061] Two fixed rails 206 are horizontally mounted on the front surface of the front plate 105. A movable plate 205 is slidably mounted on the front surface of the fixed rails 206. A slider that slides with the fixed rails 206 is provided on the rear surface of the movable plate 205. The two are slidably connected, which facilitates movement as the position of the connecting rod 204 changes.

[0062] A connecting rod 204 is installed between the rotating wheel 203 and the movable plate 205. An eccentric column is provided on the rotating wheel 203. One end of the connecting rod 204 is rotatably connected to the eccentric column, and the other end of the connecting rod 204 is rotatably connected to the movable plate 205.

[0063] In this embodiment, preferably, the adjusting member 400 is vertically installed on the front surface of the moving plate 205, and the pressure regulating mechanism 300 also includes a support plate 304 fixed on the rear surface of the lower end of the adjusting member 400, and an arc-shaped protrusion 305 fixed on the upper surface of the rear end of the support plate 304.

[0064] In this embodiment, preferably, the lateral pressure regulating component 301 that cooperates with the arc-shaped protrusion 305 includes:

[0065] A longitudinal rail 3011 is fixed inside the support 102. A drive cylinder 3013 is provided on the rear surface of the support 102. The front end of the piston rod inside the drive cylinder 3013 is fixed on the rear surface of the slide block 3012. The slide block 3012 is slidably arranged on the longitudinal rail 3011. A mounting bracket 3014 is provided inside the slide block 3012 to facilitate changing the front and rear positions of the mounting bracket 3014 and the mounting roller 3015.

[0066] A mounting roller 3015 is installed between two mounting brackets 3014. The mounting roller 3015 is provided with multiple sets of arc-shaped block groups 3016 that cooperate with arc-shaped protrusions 305. Each set of arc-shaped block groups 3016 includes multiple arc-shaped blocks, and the distance between the multiple arc-shaped blocks in each set is different, and the length of the multiple arc-shaped blocks extending out of the mounting roller 3015 in each set is different. For example, when two adjacent sets of arc-shaped blocks extend out of the mounting roller 3015 for the same length, but the distance between the adjacent arc-shaped blocks is different, they cooperate with the arc-shaped protrusions 305 respectively, which can form the same pressure depth of the friction wheel 104 on the carbon slide plate 103, but the pressure peaks and valleys have different frequencies, thereby simulating different vibration frequencies of the carbon slide plate 103. If the distance between the arc-shaped blocks is the same, but the length of the arc-shaped blocks extending out of the mounting roller 3015 is different, the distance between the peaks and valleys of the friction wheel 104 is the same, but the depth of the peaks and valleys is different, thereby simulating different pressure ranges on the carbon slide plate 103, and conducting a more comprehensive friction test on the carbon slide plate 103.

[0067] An adjustment motor 3017 is installed on the outside of one of the mounting brackets 3014, and the output shaft of the adjustment motor 3017 is connected to the mounting roller 3015.

[0068] In this embodiment, preferably, the pressure detection component 303 for detecting the downward pressure of the friction wheel 104 includes:

[0069] A fixing bracket 3031 is fixed to the lower surface of the two mounting brackets 3014, and a pressure plate 3033 is horizontally arranged inside the fixing bracket 3031;

[0070] Multiple balls 3032 installed on the upper surface of the pressure plate 3033 can reduce the frictional resistance to the movement of the support plate 304 during the movement of the adjusting component 400. The balls 3032 are in contact with the lower surface of the support plate 304.

[0071] Multiple pressure sensors 3034 are embedded in the bottom of the fixing frame 3031 to facilitate the detection of the pressure of the support plate 304 pressing down, thereby detecting the pressure of the friction wheel 104 moving downward. The upper end of the pressure sensor 3034 is in contact with the bottom of the pressure plate 3033.

[0072] In this embodiment, preferably, the height of the friction wheel 104 can be changed using the adjusting member 400 to facilitate the friction wheel 104 contacting the surface of the carbon slide plate 103 for wear testing. The adjusting member 400 for adjusting the height of the friction wheel 104 includes:

[0073] A stabilizing seat 401 is fixed to the front surface of the front plate 105, and an adjusting screw 403 is embedded inside the stabilizing seat 401.

[0074] The nut seat 402, which is threadedly connected to the adjusting screw 403, has a sliding groove on the front surface of the front plate 105. The rear surface of the nut seat 402 slides in the sliding groove, which limits the movement of the nut seat 402 and prevents it from deviating. The nut seat 402 is slidably connected to the front plate 105.

[0075] A mounting plate 404 is installed below the nut seat 402. A friction wheel 104 is installed on the lower surface of the mounting plate 404. The mounting plate 404 is elastically connected to the nut seat 402.

[0076] In summary, when a constant pressure is applied to the surface of the carbon slide plate 103 for friction and wear testing, the piston rod inside the drive cylinder 3013 is in a retracted state, the slide block 3012 is located behind the longitudinal rail 3011, and the mounting roller 3015 is located behind the arc-shaped protrusion 305. However, at this time, the support plate 304 is still in contact with the ball bearing 3032. By gripping the handwheel at the upper end of the adjusting screw 403 and rotating it, the nut seat 402 moves downward, causing the fixing rod 405 to move downward. The mounting plate 404 naturally moves downward due to gravity until the friction wheel 104 contacts the upper surface of the carbon slide plate 103, utilizing pressure transmission... Sensor 3034 detects the pressure of support plate 304 on pressure plate 3033. Since support plate 304, mounting plate 404, and friction wheel 104 are fixed, the pressure of friction wheel 104 on carbon slide plate 103 can be detected by detecting the downward pressure of support plate 304. Friction wheel 104 rotates to test the longitudinal friction and wear of carbon slide plate 103. During the transverse test, drive motor 202 works, driving rotating wheel 203 to rotate. The eccentric column on it rotates, driving connecting rod 204 to move left or right with the rotation of eccentric column, and driving moving plate 205 to move left or right along fixed rail 206. Moving to the right causes the adjusting component 400 mounted on the moving plate 205 to move, thereby causing the friction wheel 104 to move left and right to perform a lateral friction and wear test on the carbon slide plate 103. When additional pressure is required, the friction wheel 104 remains in contact with the upper surface of the carbon slide plate 103. Holding the adjusting screw 403 and rotating it causes the nut seat 402 to continue moving downward, the fixing rod 405 to move downward, and the reset component 407 to be in a stretched state. The resulting elastic rebound force causes the guide protrusion 406, the mounting plate 404, and the support plate 304 to tend to move downward, thereby increasing the pressure exerted by the support plate 304 on the carbon slide plate 103. The pressure of the pressure plate 3033, combined with the reciprocating component 200 driving the friction wheel 104 to move left and right, can detect the friction and wear test of the carbon slide plate 103 within different constant pressure ranges. For example, if the initial pressure is 0, then considering the elastic change of the reset component 407, there is a small range of pressure fluctuation, but this pressure range is within the error range. Similarly, if the pressure is increased to 10 Pa, then the pressure error range is added, which is also 10 Pa plus the error pressure. And if the pressure does not fluctuate significantly throughout the process, then it can be considered a constant pressure range, increasing the comprehensiveness of the friction test detection of the carbon slide plate 103.

[0077] When it is necessary to simulate the pressure changes caused by vibration to conduct a friction and wear test on the surface of the carbon slide plate 103, the friction wheel 104 can be kept in contact with the upper surface of the carbon slide plate 103 and located outside the arc-shaped block on the surface of the mounting roller 3015. At this time, the drive cylinder 3013 works, and its internal piston rod extends to drive the slide block 3012 to move forward along the longitudinal rail 3011, driving the mounting frame 3014 and the mounting roller 3015 to move forward until the arc-shaped protrusion 305 is aligned with the arc-shaped block on the surface of the mounting roller 3015. The drive cylinder 3013 stops working. When the reciprocating component 200 and the adjusting component 400 move to the right, the support plate 3015 is driven to move. 4. The arc-shaped protrusion 305 moves to the right, and the arc-shaped end of the arc-shaped protrusion 305 mates with the arc-shaped end of the arc-shaped block on the mounting roller 3015. The height of the mounting roller 3015 is fixed. Therefore, when the arc-shaped protrusion 305 mates with the arc-shaped block, it will cause the arc-shaped protrusion 305 to move downward, driving the mounting plate 404 and the support plate 304 to move downward. The pressure applied by the downward movement is detected by the pressure sensor 3034 at any time. The reset piece 407 is compressed as the mounting plate 404 moves downward. When the arc-shaped protrusion 305 moves away from the arc-shaped block to the gap between the adjacent arc-shaped blocks, the reset piece 407 resets, driving the mounting plate 404 to move upward and reset. When no external force is applied, the mounting plate 404 displays the initial height of the reset component 407 due to gravity. Under external force, the reset component 407 deforms, causing the height of the mounting plate 404 to fall below the initial height. The reset component 407 then resets, causing the mounting plate 404 to move upwards towards its initial height. Throughout this process, as the adjusting component 400 moves right or left, the moving arc-shaped protrusion 305 continuously engages with multiple arc-shaped blocks, achieving continuous up-and-down movement of the mounting plate 404 and the friction wheel 104. This creates fluctuating pressure on the carbon sliding plate body 103, and the same... The set of arc-shaped blocks and arc-shaped protrusions 305 cooperate, and the reciprocating movement of the friction wheel 104 simulates the pressure vibration range of the carbon slide plate 103 within the error range. When changing the pressure vibration range, the adjusting motor 3017 is activated, driving the mounting roller 3015 to rotate, so that another set of arc-shaped blocks rotates to the position that cooperates with the arc-shaped protrusions 305. By continuing the above operation, different pressure fluctuation ranges can be simulated during the transverse friction and wear test of the carbon slide plate 103, and the friction and wear test of the carbon slide plate 103 surface can be performed more comprehensively. This simulates the friction of the carbon slide plate 103 by real vibration, and provides more comprehensive data reference for the wear resistance test of the carbon slide plate 103.

[0078] Example 2

[0079] Reference Figure 6 and Figure 7 This is the second embodiment of the present invention.

[0080] In this embodiment, preferably, the adjusting component 400 further includes two fixing rods 405 fixed to the lower surface of the nut seat 402. A limiting plate is provided at the lower end of the fixing rod 405. A guide protrusion 406 is provided on the front surface of the mounting plate 404 and sleeved on the fixing rod 405. A reset component 407 is sleeved on the fixing rod 405. The upper and lower ends of the reset component 407 are respectively fixed to the lower surface of the guide protrusion 406 and the upper surface of the limiting plate.

[0081] In this embodiment, preferably, the pressure regulating mechanism 300 further includes a rotary pressure regulating component 302 that cooperates with the arc-shaped protrusion 305. Using the pressure regulating mechanism 300, during the longitudinal friction test of the carbon slide plate 103 by the rotating friction wheel 104, it can cooperate with the arc-shaped protrusion 305 to regulate the pressure, achieving alternating constant pressure and applied pressure on the friction wheel 104 during longitudinal wear, thereby simulating vibration pressure similar to that in an actual track system, and more comprehensively conducting wear tests on the carbon slide plate 103. The rotary pressure regulating component 302 includes:

[0082] A vertical plate 3021 is fixed inside the mounting bracket 3014. The vertical plate 3021 is L-shaped, and an adjustment cylinder 3022 is provided on the upper surface of the upper end of the vertical plate 3021. The piston rod inside the adjustment cylinder 3022 is fixed to the end of the mounting horizontal plate 3023. A sliding hole is opened on the surface of the vertical plate 3021. The end of the mounting horizontal plate 3023 is slidably engaged with the sliding hole. The mounting horizontal plate 3023 is slidably arranged between the two vertical plates 3021.

[0083] A rotary motor 3024 is installed on the upper surface of the mounting plate 3023. The lower end of the output shaft of the rotary motor 3024 is connected to a center roller 3025. The center roller 3025 is located behind the mounting roller 3015. When the arc-shaped protrusion 305 cooperates with the arc-shaped block on the mounting roller 3015, the center roller 3025 will not affect the cooperation between the two. When the arc-shaped protrusion 305 cooperates with the spinning wheel 3026, the arc-shaped protrusion 305 passes through the arc-shaped block spacing on the mounting roller 3015 and is located on the rear side. The mounting roller 3015 will not affect the cooperation between the center roller 3025 and the arc-shaped protrusion 305, which facilitates the rotation of the center roller 3025.

[0084] Multiple spinning rollers 3026 are installed on the center roller 3025, and the bevel depth of each spinning roller 3026 is different. When they cooperate with the arc-shaped protrusion 305, the different bevel depths can drive the arc-shaped protrusion 305 to press down to different depths.

[0085] In summary, during use, the rotating wheel 203 rotates under the drive of the motor, causing the regulating cylinder 3022 to operate. The piston rod inside the regulating cylinder 3022 moves, causing the mounting plate 3023 to move up or down, thus changing the height of the center roller 3025. This changes the height of several spinning rollers 3026 until one of the spinning rollers 3026 is at the appropriate height. The regulating cylinder 3022 then stops operating, and the drive cylinder 3013 operates, extending its piston rod. This causes the slide block 3012 and its mounting bracket 3014 to move forward along the longitudinal rail 3011, thus moving the center roller 3025... 025 and the spinning roller 3026 move forward and contact the lower bevel of the arc-shaped protrusion 305. The mounting bracket 3014 moves forward, driving the fixing bracket 3031 forward. The ball bearing 3032 remains in contact with the lower surface of the support plate 304. The rotary motor 3024 operates, driving the center roller 3025 and the spinning roller 3026 to rotate. The lower bevel of the spinning roller 3026 engages with the arc-shaped protrusion 305. As the thicker end of the spinning roller 3026 gradually rotates and engages with the arc-shaped protrusion 305, the gradually thickening bevel presses the arc-shaped protrusion 305 downwards, driving the support... The support plate 304 and the mounting plate 404 move downwards. The downward pressure of the support plate 304 also acts on the pressure plate 3033. The pressure sensor 3034 detects the downward pressure applied by the friction wheel 104. The detailed detection principle and installation method of the pressure sensor 3034 are existing technologies and will not be described in detail in this application. The reset member 407 is gradually compressed, which drives the friction wheel 104 to move downwards and act on the carbon slide plate 103, applying additional pressure to the carbon slide plate 103. When the thinner end of the spinning wheel 3026 rotates to... At the arc-shaped protrusion 305, the reset component 407 resets and drives the mounting plate 404 to move upward, reducing the pressure of the friction wheel 104 on the carbon slide plate 103. As the spinning wheel 3026 continues to rotate, the pressure of the friction wheel 104 on the carbon slide plate 104 is kept within a suitable pressure fluctuation range. With different spinning wheels 3026 cooperating with the arc-shaped protrusion 305, the different pressure ranges applied by the friction wheel 104 to the carbon slide plate 103 are adjusted, simulating different vibration ranges of the carbon slide plate 103, and improving the comprehensiveness of the wear test of the carbon slide plate 103.

[0086] Example 3

[0087] Reference Figure 8 and Figure 9 This is the third embodiment of the present invention.

[0088] In this embodiment, preferably, a workbench 101 is provided on the upper surface of the base 100, and two sets of clamping members 500 are provided on the upper surface of the workbench 101 for clamping and fixing the carbon slide plate 103. By providing the clamping members 500, the carbon slide plate 103 can be supported and clamped, which facilitates the friction wheel 104 to perform longitudinal and transverse friction tests on the carbon slide plate 103, and can adapt to carbon slide plates 103 of different specifications within a certain range, which facilitates the disassembly and replacement of the carbon slide plate 103 and provides convenience for the testing of the carbon slide plate 103. The clamping members 500 include:

[0089] A base plate 501 is horizontally located on the lower surface of the carbon slide plate 103. Clamping plates 503 that clamp the front and rear surfaces of the carbon slide plate 103 are slidably installed on the front and rear ends of the base plate 501. The upper end of the clamping plates 503 will not extend beyond the upper surface of the carbon slide plate 103 and will not affect the contact of the friction wheel 104 with the upper surface of the carbon slide plate 103.

[0090] A bearing housing 502 is installed on the lower surface of the center of the base plate 501. A double-acting lead screw 504 is installed inside the bearing housing 502. A bearing is embedded between the two to facilitate the rotation of the double-acting lead screw 504 in place.

[0091] The support feet 505 installed between the lower surface of the base plate 501 and the worktable 101 provide support and fixation for the base plate 501.

[0092] In this embodiment, preferably, the clamping plate 503 is T-shaped, the lower end of the clamping plate 503 is threadedly connected to the bidirectional lead screw 504, the end of the bidirectional lead screw 504 is provided with a handwheel, and the front and rear end surfaces of the base plate 501 are provided with rectangular holes. The lower end of the clamping plate 503 is slidably engaged with the rectangular holes, so that the clamping plate 503 will not deflect when it is threadedly engaged with the bidirectional lead screw 504.

[0093] In summary, during use, sufficient space is left between the two clamping plates 503. The carbon slide plate 103 to be tested is placed on the base plate 501, positioned between the two clamping plates 503. The handwheel is held to drive the bidirectional lead screw 504 to rotate, and the lower end of the clamping plate 503 is threadedly connected to the bidirectional lead screw 504. The lower end of the clamping plate 503 is also slidably engaged with the base plate 501 for limiting, so that the clamping plate 503 moves relative to the bidirectional lead screw 504 as it rotates. The two clamping plates 503 eventually abut against the front and rear surfaces of the carbon slide plate 103, stably clamping and fixing the carbon slide plate 103, which facilitates the carbon slide plate 103 to cooperate with the friction wheel 104 for wear testing.

[0094] Example 4

[0095] This embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0096] In use, the carbon slide plate 103 is fixed on the worktable 101 by the clamping member 500. The reciprocating member 200 is used to simulate the lateral friction and wear test of the friction wheel 104 on the carbon slide plate 103. The reciprocating member 200, together with the lateral pressure control member 301, simulates the influence of the fluctuating pressure of the friction wheel 104 on the carbon slide plate 103 during the lateral friction and wear test. During the rotation of the friction wheel 104, together with the rotation pressure control member 302, the influence of the fluctuating pressure of the friction wheel 104 on the carbon slide plate 103 during the longitudinal test is simulated, providing a more comprehensive reference for the wear test of the carbon slide plate 103. In this application, under the premise of satisfying the working principle, the size and shape of the structure can be set and deformed according to actual needs without any conflict with the principle.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
