Description

Technical Field

[0001] This utility model relates to the field of friction plate testing technology, specifically a friction plate testing device. Background Technology

[0002] Friction plates are components consisting of a chip and friction linings or layers of friction material, widely used in mechanical engineering, mechanical parts, and clutches. Existing technologies for inspecting friction plates have the following problems:

[0003] Currently, existing technologies for testing friction plates often make it inconvenient to pull the friction plate from the opposite direction, thus making it difficult to observe whether the friction plate has broken. This makes the strength testing of the friction plate relatively inconvenient. Therefore, a friction plate testing device is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a friction plate detection device to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a friction plate testing device, including a worktable, wherein a strength testing mechanism is provided on the worktable;

[0006] The strength testing mechanism includes: a rotating shaft, a guide sleeve, and an electric hydraulic cylinder. The rotating shaft is rotatably connected to the top of the worktable via bearings. A triangular plate is fixedly connected to the top of the rotating shaft, and a sliding hole is formed at the top of the triangular plate. The guide sleeve is fixedly connected to the top of the worktable, and a slide bar is slidably connected to the inner wall of the guide sleeve. An arc-shaped block is fixedly connected to the top of the slide bar, and a slide rod is fixedly connected to the bottom of the slide bar. The electric hydraulic cylinder is connected to the bottom of the worktable via a bracket, and a rack is fixedly connected to the piston end of the electric hydraulic cylinder. The bottom end of the rotating shaft passes through the worktable and extends towards... The shaft extends downwards, and a gear is fixedly connected to the extended end of the shaft. By activating the electric hydraulic cylinder to extend and retract, the rack moves, and the rack drives the gear to rotate the shaft. This causes the shaft to rotate the triangular plate, while the slide rod slides in the sliding hole. This causes the triangular plate to move the slide rod, and the slide rod to move the slide bar horizontally along the guide sleeve. This causes the slide bar to move the arc-shaped block to apply an outward thrust to the friction plate placed at the detection position, simulating the force situation in actual use. This allows for the detection of the strength of the friction plate and facilitates the observation of whether the friction plate is broken. This solves the problem that traditional detection methods cannot conveniently pull the friction plate backwards to detect its strength.

[0007] Preferably, the gear meshes with the rack, and the movement of the rack can drive the gear to rotate. The slide rod is slidably connected to the inner wall of the slide hole, and the rotation of the triangular plate can drive the slide rod to slide along the inner wall of the slide hole.

[0008] Preferably, there are three of each of the sliding holes, guide sleeves, sliding strips, arc blocks, and sliding rods, arranged in an equally spaced circular pattern. This allows for the simultaneous application of outward thrust to the friction plate from multiple directions, ensuring that all parts of the friction plate receive a relatively balanced thrust during the testing process. This simulates the stress conditions of the friction plate in actual use scenarios, avoiding inaccurate test results due to uneven stress distribution. This improves the comprehensiveness and accuracy of the test, and more realistically reflects the strength performance of the friction plate.

[0009] Preferably, a rubber pad is adhered to the outer wall of each arc-shaped block. The rubber pad has a large frictional force, which can increase the frictional force between the arc-shaped block and the friction plate, making it less likely for the arc-shaped block to slip when pushing the friction plate. This ensures the effective transmission of tension during the testing process and guarantees the accuracy of the test results. At the same time, the rubber pad is relatively soft, which can protect the surface of the friction plate to a certain extent and avoid damage to the friction plate due to hard contact during the testing process, which would affect its subsequent use or the judgment of the test results.

[0010] Preferably, the workbench is equipped with a protective mechanism, which includes: a frame, the frame being fixedly connected to the top of the workbench, a lead screw being rotatably connected to the inner top of the frame via a bearing, a slider being threadedly connected to the outer wall of the lead screw, and a transparent protective cover being fixedly connected to the front of the slider and located directly above a triangular plate. The lead screw rotation drives the slider to move vertically under the limit of the slide groove, and the slider drives the transparent protective cover to descend and cover the friction plate, which can effectively prevent the friction plate from scattering fragments when it breaks under force, thus protecting the operator and surrounding equipment and improving the safety of the testing process.

[0011] Preferably, the frame is provided with a sliding groove, and the back of the slider is slidably connected in the sliding groove. The sliding groove limits the slider, so that the rotational motion of the slider is converted into vertical movement.

[0012] Preferably, a motor is connected to the top of the frame, and the top end of the lead screw passes through the frame and is fixedly connected to the output end of the motor through a coupling. The lead screw is driven to rotate by starting the motor, thus providing power to the lead screw.

[0013] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0014] 1. This friction plate testing device uses an electric hydraulic cylinder to extend and retract, causing a rack to move. The rack drives a gear to rotate a shaft, which in turn rotates a triangular plate. Simultaneously, a sliding rod slides within a sliding hole, causing the triangular plate to move the sliding rod. The sliding rod then moves a sliding strip horizontally along a guide sleeve, causing the sliding strip to drive an arc-shaped block to apply an outward thrust to the friction plate placed at the testing position. This simulates the stress conditions in actual use, thereby testing the strength of the friction plate and facilitating the observation of whether the friction plate is broken. This solves the problem of traditional testing methods where it is inconvenient to pull the friction plate from the opposite direction to test its strength.

[0015] 2. This friction plate testing device uses a motor to drive a lead screw to rotate. The rotation of the lead screw causes a slider to move vertically under the limit of the slide groove. The slider causes a transparent protective cover to descend and cover the friction plate. This effectively prevents the friction plate from scattering fragments when it breaks under stress, protecting the operator and surrounding equipment and improving the safety of the testing process.

[0021] 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.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0025] Please see Figure 1-4One embodiment of this utility model is as follows: a friction plate testing device, including a workbench 1, with support legs fixedly connected to the four corners of the bottom of the workbench 1, and a strength testing mechanism 2 provided on the workbench 1; the strength testing mechanism 2 includes: a rotating shaft 21, a guide sleeve 24, and an electric hydraulic cylinder 28. The rotating shaft 21 is rotatably connected to the top of the workbench 1 via bearings, and a triangular plate 22 is fixedly connected to the top of the rotating shaft 21. A sliding hole 23 is opened on the top of the triangular plate 22. The guide sleeve 24 is fixedly connected to the top of the workbench 1, and a slide bar 25 is slidably connected to the inner wall of the guide sleeve 24. An arc-shaped block 26 is fixedly connected to the top of the slide bar 25, and a slide rod 27 is fixedly connected to the bottom of the slide bar 25. The slide rod 27 is slidably connected to the inner wall of the sliding hole 23. When the triangular plate 22 rotates, it can drive the slide rod 27 to slide along the inner wall of the sliding hole 23. The electric hydraulic cylinder 28 is connected to the bottom of the workbench 1 via a bracket, and the electric hydraulic cylinder 28 is a self-locking type. The piston end of the electric hydraulic cylinder 28 is fixedly connected to a rack 29. The bottom end of the rotating shaft 21 passes through the worktable 1 and extends downward. The extended end of the rotating shaft 21 is fixedly connected to a gear 210. The gear 210 meshes with the rack 29. The movement of the rack 29 can drive the gear 210 to rotate. By starting the electric hydraulic cylinder 28 to extend and retract, the rack 29 is moved. The rack 29 drives the gear 210 to rotate the rotating shaft 21, which in turn drives the triangular plate 22 to rotate. At the same time, the slide rod 27 slides in the sliding hole 23, which in turn drives the triangular plate 22 to move the slide rod 27. The slide rod 27 drives the slide bar 25 to slide horizontally along the guide sleeve 24, which causes the slide bar 25 to drive the arc block 26 to apply an outward pushing force to the friction plate placed at the detection position, simulating the force situation in actual use, thereby detecting the strength of the friction plate and facilitating the observation of whether the friction plate is broken. This solves the problem that the traditional detection method is inconvenient to pull the friction plate backward to detect its strength.

[0026] There are three of each of the following components: sliding hole 23, guide sleeve 24, sliding strip 25, arc-shaped block 26, and sliding rod 27. They are arranged in an evenly spaced circular pattern, which can simultaneously apply outward thrust to the friction plate from multiple directions. This ensures that all parts of the friction plate are subjected to a relatively balanced thrust during the testing process, simulating the stress conditions of the friction plate in actual use scenarios. This avoids inaccurate test results due to uneven force distribution, improving the comprehensiveness and accuracy of the test and more realistically reflecting the strength performance of the friction plate. Each arc-shaped block 26 has a rubber pad bonded to its outer wall. The rubber pad has a large frictional force, which increases the friction between the arc-shaped block 26 and the friction plate, making it less likely for the arc-shaped block 26 to slip when pushing the friction plate. This ensures the effective transmission of tensile force during the test and guarantees the accuracy of the test results. At the same time, the rubber pad is relatively soft, which can protect the surface of the friction plate to a certain extent and prevent damage to the friction plate due to hard contact during the test, thus affecting its subsequent use or the judgment of the test results.

[0027] Working principle: The friction plate is placed on the slide bar 25 and the outer wall of the arc block 26 is made to fit against the inner wall of the friction plate. By starting the electric hydraulic cylinder 28 to extend and retract, the rack 29 moves. The rack 29 drives the gear 210 to rotate the shaft 21, which in turn drives the triangular plate 22 to rotate. At the same time, the slide rod 27 slides in the sliding hole 23, which in turn drives the triangular plate 22 to move the slide rod 27. The slide rod 27 drives the slide bar 25 to slide horizontally along the guide sleeve 24, so that the slide bar 25 drives the arc block 26 to apply an outward pushing force to the friction plate placed at the detection position, thereby detecting the strength of the friction plate and facilitating the observation of whether the friction plate is broken.

[0028] Please see Figure 1-4 Based on the above embodiments, in another embodiment of this utility model, a protective mechanism 3 is provided on the workbench 1. The protective mechanism 3 includes: a frame 31, which is fixedly connected to the top of the workbench 1. A lead screw 32 is rotatably connected to the inner side of the top of the frame 31 via a bearing. A slider 33 is threadedly connected to the outer wall of the lead screw 32. A groove is provided on the frame 31, and the back of the slider 33 is slidably connected to the groove. The groove limits the slider 33, so that the rotational movement of the slider 33 is converted into vertical movement. A transparent protective shield is fixedly connected to the front of the slider 33. The cover 34 is located directly above the triangular plate 22. The top of the frame 31 is connected to the motor 35. The top of the lead screw 32 passes through the frame 31 and is fixedly connected to the output end of the motor 35 through a coupling. By starting the motor 35, the lead screw 32 is driven to rotate, providing power to the lead screw 32. The rotation of the lead screw 32 drives the slider 33 to move vertically under the limit of the slide groove. The slider 33 drives the transparent protective cover 34 to descend and cover the friction plate. This can effectively prevent the friction plate from flying fragments when it breaks under force, protect the operators and surrounding equipment, and improve the safety of the testing process.

[0029] Working principle: The motor 35 drives the lead screw 32 to rotate. The rotation of the lead screw 32 causes the slider 33 to move vertically under the limit of the slide groove. The slider 33 causes the transparent protective cover 34 to descend and cover the friction plate. This can effectively prevent the friction plate from flying fragments when it breaks under force, thus protecting the operator and surrounding equipment.

[0030] It is worth noting that the electric hydraulic cylinder 28 and motor 35 in the above embodiments are common equipment in the prior art. The models used can be customized according to actual usage requirements. In addition, the power supply interface of the electrical equipment in this utility model is connected to the power supply system through a switch (not shown in the figure) and wires (not shown in the figure) to realize its control.

Therefore, they will not be described in detail here.

The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
