Description

Technical Field

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

[0002] Clutch discs are composite materials whose primary function is friction, while also requiring structural performance.

[0003] Friction materials used in automobiles are mainly used to manufacture brake friction pads and clutch discs. These friction materials are primarily asbestos-based, but with increasingly stringent requirements for environmental protection and safety, semi-metallic friction materials, composite fiber friction materials, and ceramic fiber friction materials have gradually emerged.

[0004] Since friction materials are mainly used in automobiles to manufacture parts for braking and transmission systems, they are required to have a sufficiently high and stable coefficient of friction and good wear resistance.

[0005] Friction plates are an important component of the clutch. To improve assembly quality during clutch assembly, the friction plates are typically inspected to prevent damaged or substandard plates from being installed and affecting the clutch's operation. Currently, there are generally two types of inspection methods:

[0006] 1. The friction pad is fixed by a gripper or suction cup and then detected by a vision sensor. However, this detection method can affect the detection accuracy because the gripper or suction cup will block part of the friction pad.

[0007] 2. Place the friction pad directly on the testing table and design a vision sensor on the top of the testing table for detection. Although this detection method does not have the obstruction area of ​​the gripper or suction cup, because the friction pad and the vision sensor are relatively fixed, some cracks or damage features are not obvious at this fixed angle, which can easily affect the detection accuracy. Utility Model Content

[0008] Purpose of the utility model: To provide a clutch friction plate testing device to solve the above-mentioned problems existing in the prior art.

[0009] Technical solution: A clutch friction plate testing device, comprising:

[0010] A tabletop, with a fixed position set on the tabletop;

[0011] The platform is equipped with detection positions located on both sides of the fixed position;

[0012] The fixed position includes a rotating unit mounted on the table surface and a fixed unit connected to the rotating unit;

[0013] The fixing unit includes:

[0014] The limiting plate is designed in two pieces. Each limiting plate has multiple sliding grooves arranged in a circular array. A guide rod is connected between the two limiting plates. The limiting plate is circular and the guide rod is located at the center of the circle.

[0015] A movable frame is fitted onto the guide rod. A fixed cylinder is provided on one side of the movable frame. The output end of the fixed cylinder is connected to a limiting piece near the fixed cylinder.

[0016] The abutment is designed in multiple sets and distributed in a circumferential array along the movable frame. Each set of abutment includes a hinge frame that is hinged to the movable frame, and an abutment that is hinged to the hinge frame and adapted to the slide groove.

[0017] The two ends of the support frame are equipped with multiple pulleys located on both sides of the limiting plate, and the pulleys are designed to adapt to the movement of the support frame.

[0018] This utility model completes the inspection of the friction plate by designing a fixed position and inspection positions on both sides of the fixed position. During inspection, the friction plate is fixed by being sleeved on the abutment part through its own through hole, and then the friction plate is rotated one revolution by the rotating unit to complete the inspection of the friction plate.

[0019] Compared with traditional clamps, suction cups and other fixing methods, this application uses the through hole on the friction plate itself, so that the friction plate will not be blocked when it is fixed;

[0020] Meanwhile, the friction plate rotates once for detection. Because the vision sensor has a wide angle, the position and angle of the friction plate and the vision sensor change, thus avoiding the situation where some damage features are not obvious at a certain angle, resulting in missed detection.

[0021] In a further embodiment, the rotating unit includes:

[0022] Two mounting brackets are designed and arranged side by side on the table surface;

[0023] A rotating shaft is inserted into the fixed frame and extends beyond the fixed frame; a drive wheel is sleeved on the rotating shaft.

[0024] A rotary motor is connected to any fixed frame, and a transmission wheel is sleeved on the output end of the rotary motor;

[0025] A drive belt is fitted onto the drive wheel and the transmission wheel.

[0026] In a further embodiment, the rotating shaft is connected to any one of the limiting plates.

[0027] In a further embodiment, the detection position includes a detection rack mounted on the table and a vision sensor mounted on the detection rack.

[0028] In a further embodiment, the detection frame is equipped with supplementary lighting, which improves the detection effect.

[0029] In a further embodiment, the outer wall of the support frame is provided with a soft layer, which can be made of rubber or sponge, etc.

[0030] Beneficial effects: This utility model discloses a clutch friction plate testing device. This utility model completes the testing of the friction plate by designing a fixed position and testing positions on both sides of the fixed position. During testing, the friction plate is fixed by being sleeved on the abutment part through its own through hole, and then the friction plate is rotated one revolution by the rotating unit to complete the testing of the friction plate.

[0031] Compared with traditional clamps, suction cups and other fixing methods, this application uses the through hole on the friction plate itself, so that the friction plate will not be blocked when it is fixed;

[0032] Meanwhile, the friction plate rotates once for detection. Because the vision sensor has a wide angle, the position and angle of the friction plate and the vision sensor change, thus avoiding the situation where some damage features are not obvious at a certain angle, resulting in missed detection.

[0041] This application relates to a clutch friction plate testing device, which will be explained in detail below through specific embodiments.

[0042] A clutch friction plate testing device, comprising:

[0043] Tabletop 1, and a fixed position 3 disposed on the tabletop 1;

[0044] The platform 1 is equipped with detection positions 2 located on both sides of the fixed position 3;

[0045] The fixed position 3 includes a rotating unit installed on the table 1, and a fixed unit 32 connected to the rotating unit;

[0046] The fixing unit 32 includes:

[0047] The limiting piece 322 is designed in two pieces. Each limiting piece 322 has multiple sliding grooves 323 arranged in a circular array. A guide rod 328 is connected between the two limiting pieces 322. The limiting piece 322 is circular and the guide rod 328 is located at the center of the circle.

[0048] A movable frame 327 is sleeved on the guide rod 328. A fixed cylinder 326 is provided on one side of the movable frame 327. The output end of the fixed cylinder 326 is connected to a limiting piece 322 near the fixed cylinder 326.

[0049] The abutment is designed in multiple sets and distributed in a circumferential array along the movable frame 327. Each set of abutment includes a hinge frame 329 that is hinged to the movable frame 327, and an abutment 324 that is hinged to the hinge frame 329 and adapted to the slide groove 323.

[0050] The two ends of the support frame 324 are provided with multiple pulleys 325 located on both sides of the limiting piece 322, and the pulleys 325 are designed to adapt to the movement of the support frame 324.

[0051] This utility model completes the inspection of the friction plate by designing a fixed position 3 and inspection positions 2 on both sides of the fixed position 3. During inspection, the friction plate is fixed by being fitted onto the abutment through its own through hole, and then the friction plate is rotated one revolution by the rotating unit to complete the inspection of the friction plate.

[0052] Compared with traditional clamps, suction cups and other fixing methods, this application uses the through hole on the friction plate itself, so that the friction plate will not be blocked when it is fixed;

[0053] Simultaneously, the friction plate rotates once for detection. Since the vision sensor 22 has a wide angle, the position and angle of the friction plate and the vision sensor 22 change, thereby avoiding the phenomenon that some damage features are not obvious at a certain angle, resulting in missed detection.

[0054] This design allows for the detection of microcracks, scratches, rust spots, etc., on friction plates, and determines whether the friction plates are qualified based on the set specifications.

[0055] The rotating unit includes:

[0056] Two mounting brackets 311 are designed and arranged side by side on the table surface 1;

[0057] A rotating shaft 321 is inserted into the fixed frame 311 and extends to the outside of the fixed frame 311. A drive wheel is sleeved on the rotating shaft 321.

[0058] A rotary motor 312 is connected to any fixed frame 311, and a transmission wheel is sleeved on the output end of the rotary motor 312;

[0059] The drive belt 313 is fitted onto the drive wheel and the transmission wheel.

[0060] The rotating shaft 321 is connected to any one of the limiting pieces 322.

[0061] The detection position 2 includes a detection frame 21 mounted on the table 1 and a vision sensor 22 mounted on the detection frame 21.

[0062] The testing frame 21 is equipped with a supplementary light 23. By designing the supplementary light 23, the testing effect is improved.

[0063] The outer wall of the support frame 324 is provided with a soft layer, which can be made of rubber or sponge.

[0064] Working principle description: During operation, the friction plate is placed on the support frame 324. At this time, the fixed cylinder 326 drives the movable frame 327 to move along the guide rod 328, which in turn drives the hinge frame 329 to move, causing the support frame 324 to slide along the slide groove 323, thereby expanding outward and pressing against the inner wall of the friction plate through hole to complete the fixation.

[0065] After being fixed, the friction plate is rotated by the drive belt 313 driven by the rotary motor 312, and the detection is completed by the vision sensor 22.

[0066] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
