Description

Technical Field

[0001] This disclosure relates to the field of testing equipment, and more specifically, to a drag force testing device. Background Technology

[0002] In the production and testing of automotive braking systems and rotary machinery components, drag force (or drag torque) is a crucial indicator for evaluating caliper reset performance, friction pair separation effect, and the operating resistance of rotary components. A widely used testing method integrates the caliper and rotary disc onto a single load-bearing component (plate). By driving the rotary disc to rotate, braking the caliper, and then releasing it, the resistance torque when the rotary disc restarts is measured, thus determining whether drag exists in the caliper. This type of testing equipment is commonly used for final inspection on production lines, laboratory sampling, and changeover testing of multi-variety, small-batch components.

[0003] In existing drag force testing equipment, the load-bearing component is directly bolted to the equipment platform. The component under test (including brake discs and calipers) is then placed on the load-bearing component, and its fixed end is limited. A lifting mechanism then pushes the testing component upwards to engage with the rotary table, driving rotation for testing. Alternatively, a clamping mechanism presses the load-bearing component downwards, securing it to the support platform. A separate lifting mechanism then pushes the testing component upwards for testing. When continuously testing the same specification of component, the load-bearing component does not need to be replaced, and the testing component only needs to lower slightly after each test to allow for loading and unloading. However, when frequent replacement of different specifications of load-bearing components and their associated load-bearing components is required, the process becomes more complex. When inspecting parts (i.e., continuous changeover testing), the load-bearing components are fixed with bolts. Each changeover requires loosening multiple bolts, removing the original load-bearing components, installing the new load-bearing components, and retightening the bolts. This operation is cumbersome and time-consuming. When fixing the load-bearing components with a clamping mechanism, the clamping mechanism must be raised to release pressure before the load-bearing components are replaced. Then the clamping mechanism must be lowered again to fix the components. At the same time, the lifting mechanism of the testing components must also be lowered to make way for the new load-bearing components before being raised again for connection. This requires multiple control steps to be executed sequentially. The bolt tightening or clamping mechanism itself takes a relatively long time. In other words, the changeover process involves many steps and the waiting time at the testing station is relatively long, resulting in low overall changeover efficiency and making it difficult to meet the needs of rapid testing of multiple specifications and small batches. Summary of the Invention

[0004] The purpose of this disclosure is to provide a drag force testing device that, through the coordination of a first lifting mechanism and a second lifting mechanism, balances continuous testing under the same specifications with rapid production changeover under different specifications, thereby improving testing efficiency, multi-specification adaptability, and testing reliability.

[0020] As can be seen from the above technical solutions, the exemplary embodiments disclosed herein possess at least the following advantages and positive effects: In some embodiments of the present disclosure, when testing a carrier component and a corresponding tested component of the same specification, a first lifting mechanism is used. When the lifting end of the first lifting mechanism rises along a first direction, it cooperates with a support platform to clamp and fix the carrier component. Simultaneously, a second lifting mechanism and the testing component are raised to a working height close to the rotating part of the tested component. Then, the lifting end of the second lifting mechanism rises with a relatively short stroke, allowing the testing end of the testing component to dock with the rotating part for driving rotation and testing. After testing, the second lifting mechanism first descends with a relatively short stroke to disengage the testing end from the rotating part, and then the tested component is replaced, enabling continuous testing. When continuously testing different specifications of carrier components and corresponding inspected components, the first lifting mechanism descends after testing to release the clamping and fixing of the carrier component. At the same time, it drives the testing end of the testing component to detach from the corresponding inspected component. This reduces the number of steps required to control the descent of the second lifting mechanism during the changeover process, thereby reducing changeover time and control steps. The second lifting mechanism also avoids guide wear and sway errors caused by long-stroke lifting, improving docking stability. The synergy between the first and second lifting mechanisms balances continuous testing under the same specifications and rapid changeover under different specifications, improving testing efficiency, multi-specification adaptability, and testing reliability.

For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0028] like Figures 1 to 7 As shown, the present invention discloses a testing device, specifically applied in the scenario of drag force testing. It tests whether the rotary table is still subject to residual resistance caused by the caliper, bearing, connecting frame or assembly deviation after the caliper is released from braking. In other words, it does not test whether the caliper can stop the rotary table, but rather whether the rotary table can smoothly rotate again after the caliper is released from braking, and the magnitude of the drag force overcome by the rotation.

[0029] like Figures 1 to 7 As shown, this invention discloses a drag force detection device, comprising, Support platform 40; The carrier component 10 is provided with a testing station for carrying the corresponding inspected component 60. The inspected component 60 includes a rotating part and a stop part for stopping the rotating part. The lifting assembly 20 includes a first lifting mechanism 21 and a second lifting mechanism 22. The fixed end of the first lifting mechanism 21 is disposed on the support platform 40, and the lifting end is used to rise along the first direction to cooperate with the support platform 40 to clamp and fix the bearing assembly 10. The fixed end of the second lifting mechanism 22 is disposed on the lifting end of the first lifting mechanism 21. The detection component 30 has a fixed end set at the lifting end of the second lifting mechanism 22, and the detection end is used to dock with the rotating part of the component under test 60 located at the detection station, so as to drive the rotating part of the component under test 60 to rotate and perform drag force detection. The support platform 40 serves as the installation foundation and load-bearing reference, specifically supporting the load-bearing component 10 and the lifting component 20. The load-bearing component 10 is mounted on the support platform 40. Through the designated testing station, the component under test 60 can be placed on the testing station for inspection. The load-bearing component 10 supports the component under test 60, specifically supporting the rotating part and the stop part used to brake the rotating part. This ensures that the rotating part and the stop part maintain a predetermined relative position within the testing station. Specifically, the load-bearing component 10 limits the rotation direction of the stop part of the component under test 60. When the rotating part is driven to rotate, the stop part does not... The lifting assembly 20 includes a first lifting mechanism 21 and a second lifting mechanism 22. The fixed end of the first lifting mechanism 21 is mounted on the support platform 40. The lifting end of the first lifting mechanism 21 can rise in a first direction and, after rising, cooperates with the support platform 40 to clamp and fix the bearing assembly 10, preventing displacement of the bearing assembly 10 during testing due to rotational driving force, braking force of the stop, or vibration generated by the tested assembly 60. This ensures the tested assembly 60 is in a relatively stable testing position. The fixed end of the second lifting mechanism 22 is located on the lifting end of the first lifting mechanism 21. The lifting end of the first lifting mechanism 21 can... The second lifting mechanism 22 is driven to rise and fall. When the first lifting mechanism 21 rises to clamp and fix the bearing component 10, the second lifting mechanism 22 and the detection component 30 set on the lifting end of the second lifting mechanism 22 can rise simultaneously, that is, move closer to the rotating part of the inspected component 60. The fixed end of the detection component 30 is set on the lifting end of the second lifting mechanism 22. After the first lifting mechanism 21 completes the clamping and fixing of the bearing component 10, the second lifting mechanism 22 drives the detection component 30 to rise through the lifting end of the second lifting mechanism 22, so that the detection end of the detection component 30 docks with the rotating part. Then, the detection end of the detection component 30 drives the rotating part to rotate. The stop part brakes the rotating part and the drag force is detected after the brake is released (the drag force detection is a known technology and will not be described in detail here; the drag force is determined by continuing to drive the rotating part to rotate after the brake is released). Specifically, the first lifting mechanism 21 can simultaneously clamp and fix the bearing component 10 and lift the second lifting mechanism 22 and the detection component 30 as a whole. The second lifting mechanism 22 only needs to connect the detection component 30 to the rotating part, that is, it can relatively reduce the stroke. The detection component 30 drives the rotating part to rotate and continues to drive the rotating part to rotate when the stop part is released after braking, and simultaneously collects drag force data information. More specifically, when inspecting the same specification of the load-bearing component 10 and the corresponding inspected component 60, the first lifting mechanism 21, when its lifting end rises in the first direction, cooperates with the support platform 40 to clamp and fix the load-bearing component 10, while simultaneously raising the second lifting mechanism 22 and the inspection component 30 to near the working height of the rotating part of the inspected component 60; then, the lifting end of the second lifting mechanism 22 rises with a relatively short stroke, causing the inspection end of the inspection component 30 to dock with the rotating part, driving rotation and inspection. After the inspection is completed, the second lifting mechanism 22 first descends with a relatively short stroke to disengage the inspection end from the rotating part, and then the inspected component 60 is replaced, enabling continuous inspection. When the same specification of the carrier component 10 and the corresponding inspected component 60 are continuously tested, after the test is completed, the first lifting mechanism 21 lowers to release the clamping and fixing of the carrier component 10. At the same time, the testing end of the testing component 30 is driven to detach from the corresponding inspected component 60. This reduces the number of steps to control the lowering of the second lifting mechanism 22 during the changeover process, which can reduce the changeover time and control steps. The second lifting mechanism 22 avoids guide wear and sway error caused by long-stroke lifting, and improves docking stability. Through the coordination of the first lifting mechanism 21 and the second lifting mechanism 22, continuous testing under the same specification and rapid changeover under different specifications are taken into account, which improves the testing efficiency, multi-specification adaptability and testing reliability.

[0030] In this embodiment, as a preferred solution, the first lifting mechanism 21 includes a first driving member 211, a support plate 212, a connecting shaft 214, and a clamping member 213. The fixed end of the first driving member 211 is disposed on the surface of the support platform 40 along the first direction. The support plate 212 is fixedly connected to the lifting end of the first driving member 211. One end of the connecting shaft 214 is fixedly connected to the surface of the support plate 212 facing the support platform 40, and the other end passes through the support platform 40 and connects to the clamping member 213. Because the fixed end of the first driving member 211 is disposed on the surface of the support platform 40 along the first direction, the support platform 40 can support the first driving member 211, and the first driving member 211 can output lifting and lowering actions along the first direction. The support plate 212 is fixedly connected to the lifting end of the first driving member 211, and the lifting end of the first driving member 211 can synchronously drive the support plate 212 to lift and lower when it lifts and lowers along the first direction. One end of the connecting shaft 214 is fixedly connected to the surface of the support plate 212 facing the support platform 40. The other end of the connecting shaft 214 passes through the support platform 40 and is connected to the clamping member 213. When the lifting end of the first driving member 211 rises and falls in the first direction, it can drive the support plate 212, the connecting shaft 214 and the clamping member 213 to rise and fall synchronously in the first direction. That is, when the lifting end of the first driving member 211 rises in the first direction, the first driving member 211 drives the support plate 212 to rise in the first direction. The support plate 212 drives the clamping member 213 to move toward the bearing assembly 10 through the connecting shaft 214, so that after the clamping member 213 abuts against the bearing assembly 10, it can cooperate with the support platform 40 to clamp and fix the bearing assembly 10. When the lifting end of the first driving member 211 falls in the first direction, the first driving member 211 drives the support plate 212 to fall. The support plate 212 drives the clamping member 213 away from the bearing assembly 10 through the connecting shaft 214, so that the clamping member 213 releases its clamping effect on the bearing assembly 10. After the bearing assembly 10 is clamped and fixed, it remains in the position corresponding to the detection station during the detection process.

[0031] In this embodiment, as a preferred solution, the clamping member 213 includes an abutment block 213a, an abutment plate 213b, and a positioning block 213c. The abutment plate 213b is fixedly connected to one end of the connecting shaft 214 away from the support plate 212. The abutment block 213a is fixedly connected to the surface of the abutment plate 213b away from the connecting shaft 214. The positioning block 213c is disposed on the surface of the abutment plate 213b and located on one side of the abutment block 213a. A contact plate 213b is fixedly connected to the end of the connecting shaft 214 opposite to the support plate 212. The connecting shaft 214 supports the contact plate 213b and drives the contact plate 213b to move synchronously in the first direction when the connecting shaft 214 moves up and down in the first direction. A contact block 213a is fixedly connected to the surface of the contact plate 213b opposite to the connecting shaft 214. The contact plate 213b supports the contact block 213a. When the contact plate 213b rises in the first direction, it drives the contact block 213a to move towards the bearing assembly 10, so that the contact block 213a abuts against the bearing assembly 10 and, together with the support platform 40, clamps and fixes the bearing assembly 10. A positioning block 213c is set on the surface of the contact plate 213b and located on one side of the contact block 213a. b can support the positioning block 213c. When the abutment plate 213b rises in the first direction, it can drive the positioning block 213c to move synchronously toward the bearing component 10 along with the abutment block 213a, so that the positioning block 213c is located on one side of the bearing component 10 and positions or limits the bearing component 10. Thus, the connecting shaft 214 transmits the lifting action of the first driving member 211 to the abutment plate 213b. The abutment plate 213b synchronously drives the abutment block 213a and the positioning block 213c to move. The abutment block 213a is used to abut the bearing component 10 and cooperate with the support platform 40 to clamp and fix the bearing component 10. The positioning block 213c is used to limit the position of the bearing component 10 when the abutment block 213a abuts the bearing component 10, so that the bearing component 10 is kept in the position corresponding to the detection station during the detection process.

[0032] In this embodiment, as a preferred solution, the surface of the abutment block 213a is sequentially provided with opening slots along a third direction, and the opening slots extend along a second direction. By sequentially providing opening slots along a third direction and extending them along the second direction, the opening slots can form a clearance space extending along the second direction on the surface of the abutment block 213a. Furthermore, the solid portion between adjacent opening slots can form a support area for abutting the bearing assembly 10. When the abutment block 213a moves toward the bearing assembly 10, multiple support areas can move synchronously toward the bearing assembly 10 with the abutment block 213a and abut against different positions of the bearing assembly 10, thus providing segmented support for the bearing assembly 10. By having multiple support areas abut against the bearing assembly 10 respectively, the abutment block 213a can reduce the contact area between the abutment and the bearing assembly 10. When block 213a is fully engaged, localized suspension caused by localized protrusions or processing errors on the surface of the bearing component 10 results in the contact positions between the engagement block 213a and the bearing component 10 being dispersed across multiple areas in the third direction. By using the opening slot to avoid localized structures on the surface of the bearing component 10, interference between the engagement block 213a and the bearing component 10 can be reduced. This allows multiple support areas to fit into the corresponding positions of the bearing component 10. Thus, when the engagement block 213a, in conjunction with the support platform 40, clamps and fixes the bearing component 10, it can engage the bearing component 10 in segments through multiple support areas. This ensures that the bearing component 10 remains in the corresponding position at the inspection station after being clamped by the engagement block 213a, and reduces the offset or shaking of the bearing component 10 caused by uneven contact.

[0033] In this embodiment, as a preferred solution, the bearing assembly 10 includes a bearing plate 11, a stop block 12, and a bearing block 13. The surface of the bearing plate 11 is provided with a positioning hole 14 for the positioning block 213c to pass through. The stop block 12 is fixedly connected to the surface of the bearing plate 11 away from the abutment plate 213b, and is used to support the stop part of the tested assembly 60 and restrict its rotation. The bearing block 13 is fixedly connected to one side of the stop block 12 and is used to support the rotating part of the tested assembly 60. The surface of the bearing block 13 that is in contact with the rotating part is provided with a ceramic coating. The ceramic coating is a known technology and is only cited here. Its purpose is to improve the wear resistance of the bearing block 13 in contact with the rotating part. The support plate 11 is mounted on the support platform 40. It serves as the mounting base for the stop block 12 and the support block 13, and bears the force exerted by the inspection component 60 during the inspection process. Positioning holes 14 are formed on the surface of the support plate 11. When the first lifting mechanism 21 drives the positioning block 213c to rise in the first direction, the positioning block 213c can pass through the positioning holes 14, allowing it to engage with the holes to position and limit the support plate 11, reducing the impact on the support plate 11. When block 213a is pressed against the bearing plate 11, it shifts along the surface of the bearing plate 11. It is fixedly connected to the surface of the bearing plate 11 away from the contact plate 213b via stop block 12. The bearing plate 11 supports stop block 12, which in turn supports the stop portion of the inspected component 60. When the rotating part is driven to rotate by the inspection component 30, the stop portion is restricted from rotating synchronously with the rotating part, allowing the stop portion to remain at the inspection position corresponding to the bearing plate 11 and to brake the rotating part. It is fixedly connected to the bearing plate 11 via block 13. On one side of the stop block 12, the support plate 11 and the stop block 12 can support the support block 13. The support block 13 can support the rotating part of the tested component 60, so that the rotating part is located at the position corresponding to the detection end of the detection component 30. A ceramic coating is provided on the surface of the support block 13 that contacts the rotating part. When the rotating part comes into contact with or slightly moves relative to the support block 13 during the detection process, the ceramic coating can be located between the support block 13 and the rotating part, reducing the wear of the rotating part on the contact surface of the support block 13, and making the support block 13 more stable. During multiple tests, the carrier block 13 maintains a contact state to support the rotating part. Thus, the carrier plate 11 is used to install the stop block 12 and the carrier block 13 and cooperate with the positioning block 213c for positioning. The stop block 12 is used to support the stop part of the component under test 60 and restrict the rotation of the stop part. The carrier block 13 is used to support the rotating part of the component under test 60. The ceramic coating is used to provide wear-resistant protection for the contact surface between the carrier block 13 and the rotating part, so that the component under test 60 maintains the corresponding support position and limit state in the test station.

[0034] In this embodiment, as a preferred option, the second lifting mechanism 22 includes a second driving member 221, a lifting frame 222, and a guide shaft 223. The fixed end of the second driving member 221 is fixedly connected to the surface of the support plate 212 and is located on one side of the connecting shaft 214. One end of the guide shaft 223 is fixedly connected to the surface of the support plate 212 and is located on one side of the connecting shaft 214, and the other end is fixedly connected to the surface of the support platform 40 facing the support plate 212. The surface of the lifting frame 222 is slidably connected to the outer surface of the guide shaft 223 along the first direction through an opening. The lifting end of the second driving member 221 is fixedly connected to the lifting frame 222, and the second driving member 221 is fixedly connected to the support plate 212 through the fixed end of the second driving member 221. The support plate 212 supports the second drive member 221, allowing the second drive member 221 to rise and fall along the first direction with the support plate 212. After the support plate 212 is in the corresponding working position, it outputs a driving force to drive the lifting frame 222 to rise and fall. Since the second drive member 221 is located on one side of the connecting shaft 214, the second drive member 221 and the connecting shaft 214 can be staggered on the support plate 212, so that the connecting shaft 214 drives the clamping member 213 to abut against the bearing assembly 10, and the second drive member 221 drives the lifting frame 222 to move. The two respectively undertake the action transmission of clamping and fixing of the bearing assembly 10 and docking drive of the detection assembly 30. One end of the guide shaft 223 is fixedly connected to the surface of the support plate 212 and located on one side of the connecting shaft 214. The other end of the guide shaft 223 is fixedly connected to the surface of the support platform 40 facing the support plate 212. The guide shaft 223 can form a guide base extending in the first direction between the support plate 212 and the support platform 40. A hole is opened on the surface of the lifting frame 222, and the lifting frame 222 is slidably connected to the outer surface of the guide shaft 223 in the first direction through the hole. The guide shaft 223 can restrict the lifting direction of the lifting frame 222, so that the lifting frame 222 is not easily deviated in the second or third direction when it moves in the first direction under the drive of the second drive member 221. The lifting end of the second driving member 221 is fixedly connected to the lifting frame 222. When the lifting end of the second driving member 221 rises in the first direction, it can drive the lifting frame 222 to rise along the guide shaft 223. When the lifting end of the second driving member 221 descends in the opposite direction to the first direction, it can drive the lifting frame 222 to descend along the guide shaft 223, so that the detection component 30 mounted on the lifting frame 222 can move towards or away from the rotating part of the component under inspection 60 with the lifting frame 222. Thus, the support plate 212 is used to support one end of the second driving member 221 and the guide shaft 223, the guide shaft 223 is used to slide and guide the lifting frame 222, and the second driving member 221 is used to drive the lifting frame 222 to move in the first direction, so that the lifting frame 222 can drive the detection component 30 to complete docking or disengagement with the rotating part.

[0035] Both the first driving component 211 and the second driving component 221 can be hydraulic rods or electric telescopic rods, which are existing known technologies. They are only cited here for the purpose of driving the corresponding installed structure to rise and fall along the first direction through the lifting end.

[0036] In this embodiment, as a preferred solution, the lifting frame 222 includes a lifting plate 222a, a vertical plate 222b, and a horizontal plate 222c. The lifting plate 222a and the horizontal plate 222c are arranged sequentially along a first direction. One end of the vertical plate 222b is fixedly connected to the lifting plate 222a, and the other end is fixedly connected to the horizontal plate 222c. The surface of the lifting plate 222a is slidably connected to the outer surface of the guide shaft 223 along the first direction through an opening. The fixed end of the detection component 30 is disposed on the horizontal plate 222c. The sequential arrangement of the lifting plate 222a and the horizontal plate 222c along the first direction enables… The lifting plate 222a and the horizontal plate 222c are arranged at intervals in the first direction. One end of the vertical plate 222b is fixedly connected to the lifting plate 222a, and the other end of the vertical plate 222b is fixedly connected to the horizontal plate 222c. The vertical plate 222b can connect the lifting plate 222a and the horizontal plate 222c into a whole, so that when the lifting plate 222a moves in the first direction, the vertical plate 222b can drive the horizontal plate 222c to move synchronously in the first direction. Holes are opened on the surface of the lifting plate 222a, and the lifting plate 222a is slidably connected to the guide shaft 2 in the first direction through the holes. The outer surface of 23, the guide shaft 223 can restrict the movement direction of the lifting plate 222a, so that the lifting plate 222a rises and falls along the guide shaft 223 under the drive of the second drive member 221, and reduces the offset of the lifting plate 222a in the second or third direction. The fixed end of the detection component 30 is set on the horizontal plate 222c, and the horizontal plate 222c can support the detection component 30. When the horizontal plate 222c rises in the first direction, it can drive the detection component 30 to move toward the rotating part of the inspected component 60, so that the detection end of the detection component 30 docks with the rotating part. When 22c descends in the direction opposite to the first direction, it can drive the detection component 30 away from the rotating part of the inspected component 60, so that the detection end of the detection component 30 is disengaged from the rotating part. Specifically, the lifting plate 222a is used to slide with the guide shaft 223 and receive the lifting drive of the second driving member 221. The vertical plate 222b is used to transmit the lifting action of the lifting plate 222a to the horizontal plate 222c. The horizontal plate 222c is used to support the detection component 30 and drive the detection component 30 to move closer to or away from the rotating part in the first direction, so that the detection component 30 can complete the docking and disengagement with the rotating part.

[0037] In this embodiment, as a preferred solution, the detection component 30 includes a drive motor 31, a reducer 32, a torque sensor, and a docking part 33. The power output end of the drive motor 31 is connected to the power input end of the reducer 32. The reducer 32 is fixedly connected to the surface of the horizontal plate 222c by bolts. The power output end of the reducer 32 is coaxially connected to the input shaft of the torque sensor along a first direction via a coupling. The output shaft of the torque sensor is coaxially connected to the docking part 33 along a first direction via a coupling. Because the reducer 32 is fixedly connected to the surface of the horizontal plate 222c by bolts, the horizontal plate 222c can support the reducer 32 and allow the reducer 32 to move along the horizontal plate 222c. 2c moves up and down along the first direction. The power output end of the drive motor 31 is connected to the power input end of the reducer 32. The drive motor 31 can input rotational power to the reducer 32, which can reduce the rotational power output by the drive motor 31 and transmit torque, so that the power output end of the reducer 32 outputs power to drive the rotation of the rotating part of the tested component 60. The power output end of the reducer 32 is coaxially connected to the input shaft of the torque sensor along the first direction via a coupling. The rotational power output by the reducer 32 can be transmitted to the input shaft of the torque sensor via the coupling, and the power output end of the reducer 32 and the input shaft of the torque sensor are coaxial along the first direction. The coaxial arrangement allows the power transmission path to extend along the first direction, reducing the transmission off-center load caused by axial misalignment between the reducer 32 and the torque sensor. The output shaft of the torque sensor is coaxially connected to the docking member 33 along the first direction via a coupling. The torque sensor can transmit rotational power to the docking member 33. After the docking member 33 docks with the rotating part of the tested component 60, it collects the torque changes generated during the rotation of the rotating part. When the horizontal plate 222c rises along the first direction, it can drive the reducer 32, drive motor 31, torque sensor, and docking member 33 to move synchronously towards the rotating part of the tested component 60, allowing the docking member 33 to... After the rotating part is docked, the rotational power output by the drive motor 31 is transmitted to the rotating part in sequence through the reducer 32, coupling, torque sensor and docking part 33, causing the rotating part to rotate. After the stop part brakes the rotating part and releases the brake, the drive motor 31 continues to drive the rotating part to rotate. The torque sensor synchronously collects the drag force data information of the rotating part when it continues to rotate after the brake is released. The torque sensor is used to collect the torque change during the rotation process of the rotating part. The drive motor 31, reducer 32 and torque sensor are all existing known technologies, which will not be described in detail here. They are only cited here for the purpose of rotation drive and drag force detection.

[0038] In this embodiment, as a preferred option, the docking member 33 extends along the first direction and has a regular hexagonal cross-section. The surface of the lifting plate 222a has a clearance opening along the first direction for the docking member 33 to pass through. By extending the docking member 33 along the first direction, the docking member 33 can move towards the rotating part of the inspected component 60 along the first direction when the horizontal plate 222c drives the detection component 30 to move along the first direction. After the second driving member 221 drives the lifting frame 222 to rise, it is inserted into the docking position corresponding to the rotating part. Because the cross-section of the docking member 33 is set as a regular hexagon, when the docking member 33 cooperates with the docking structure corresponding to the rotating part, the outer peripheral surface of the regular hexagon can form a circumferential limit with the docking structure of the rotating part, so that the docking member 33 can be driven... When the rotating part rotates, it can transmit torque to the rotating part and reduce the circumferential slippage of the docking part 33 relative to the rotating part. By opening a clearance opening on the surface of the lifting plate 222a along the first direction, the docking part 33 can move to the position of the rotating part through the clearance opening, so that the lifting plate 222a will not block the docking part 33 from approaching or moving away from the rotating part along the first direction. When the horizontal plate 222c rises along the first direction, the horizontal plate 222c drives the detection component 30 and the docking part 33 to rise synchronously along the first direction. After the docking part 33 passes through the clearance opening, it docks with the rotating part. When the horizontal plate 222c descends in the opposite direction to the first direction, the horizontal plate 222c drives the detection component 30 and the docking part 33 to descend synchronously, so that the docking part 33 exits the rotating part along the clearance opening.

[0039] In this embodiment, as a preferred solution, the support platform 40 includes a plate 41 and a guide rail 42 extending in a third direction. The surface of the plate 41 is slidably connected to the connecting shaft 214 through a through hole. The surface of the plate 41 is provided with an opening for the docking piece 33 to pass through. The guide rail 42 is fixedly connected to the surface of the plate 41 and is slidably connected to the bearing plate 11 in a third direction. A through hole is formed on the surface of the plate 41, and the connecting shaft 214 is slidably connected to the through hole. The plate 41 can limit the insertion position of the connecting shaft 214, so that the connecting shaft 214 can slide relative to the plate 41 when it is raised and lowered in the first direction under the drive of the first drive member 211. The connecting shaft 214 can pass through the plate 41 to transmit the raising and lowering action of the support plate 212 to the abutting member 213, and avoid interference between the connecting shaft 214 and the plate 41 during the raising and lowering process. An opening is formed on the surface of the plate 41 for the mating member 33 to pass through. When the second driving member 221 drives the detection component 30 to move along the first direction, the docking member 33 can pass through the opening and move toward the rotating part of the inspected component 60, so that the plate body 41 will not obstruct the docking member 33 from docking or disengaging from the rotating part. It is fixedly connected to the surface of the plate body 41 by a guide rail 42 extending along a third direction. The plate body 41 can support the guide rail 42, which provides a guiding foundation for the carrier plate 11 to slide along a third direction. Through the guide rail 42 and the carrier plate 11 slidingly connected along a third direction, the carrier plate 11 can... When the guide rail 42 enters or leaves the inspection station, the inspected component 60 on the carrier plate 11 can move with the carrier plate 11 to the position corresponding to the docking component 33. When the first lifting mechanism 21 rises along the first direction, the connecting shaft 214 drives the clamping member 213 to move towards the carrier plate 11, so that the clamping member 213 cooperates with the plate body 41 to clamp and fix the carrier plate 11. The carrier plate 11 remains in the position corresponding to the inspection station during the inspection process. When the first lifting mechanism 21 descends in the opposite direction to the first direction, the connecting shaft 214 drives the clamping member 213 to move towards the carrier plate 11. When the movable clamping member 213 moves away from the carrier plate 11, the clamping member 213 releases its clamping and fixing of the carrier plate 11, and the carrier plate 11 can slide away from the inspection station along the guide rail 42. Another carrier plate 11 can slide into the inspection station along the guide rail 42. The carrier plate 11 and the inspected component 60 corresponding to the carrier plate 11 can be set in advance. That is, carrier plates 11 with different bearing specifications correspond to inspected components 60 with different specifications. The inspected components 60 can be switched relatively quickly, further reducing the changeover time and effectively improving the inspection efficiency.

[0040] A clamping plate is also fixedly connected to the surface of the plate 41. At least part of the projection of the clamping plate along the first direction coincides with the support plate 11, and is used to cooperate with the clamping member 213 to clamp and fix the support plate 11.

[0041] In this embodiment, as a preferred solution, a guide plate 15 extending in a second direction is fixedly connected to the surface of the support plate 11 facing the plate body 41. One surface of the guide plate 15 along the second direction is in contact with the surface of the guide rail 42 along the second direction. The guide plate 15 is fixedly connected to the surface of the support plate 11 facing the plate body 41, allowing the support plate 11 to support the guide plate 15 and drive the guide plate 15 to move synchronously when the support plate 11 slides along the guide rail 42. Because the guide plate 15 extends in the second direction, it can form a guiding contact portion arranged in the second direction on one side of the support plate 11 facing the plate body 41, enabling the guide plate 15 to form a corresponding contact relationship with the guide rail 42. The guide plate 15, through the contact connection between one surface of the guide plate 15 along the second direction and the surface of the guide rail 42 along the second direction, allows the guide plate 15 to move synchronously when the support plate 11 slides along the guide rail 42. When sliding in the third direction, the bearing plate 11 moves against the corresponding surface of the guide rail 42, so that the guide rail 42 restricts the position of the bearing plate 11 in the second direction through the guide plate 15, reducing the offset of the bearing plate 11 in the second direction. When the bearing plate 11 enters or leaves the inspection station along the guide rail 42, the guide plate 15 moves with the bearing plate 11 in the third direction. The contact connection between the guide plate 15 and the guide rail 42 can constrain the sliding direction of the bearing plate 11, so that the bearing plate 11 moves in the extension direction of the guide rail 42. When the bearing plate 11 moves to the inspection station, the contact cooperation between the guide plate 15 and the guide rail 42 can keep the bearing plate 11 in the position corresponding to the plate body 41, so that the first lifting mechanism 21 can drive the positioning block 213c to cooperate with the positioning hole 14 on the bearing plate 11, and facilitate the docking part 33 to dock with the rotating part of the inspected component 60.

[0042] In this embodiment, as a preferred solution, the support platform 40 further includes a support frame 43 and a stabilizing mechanism 44. The support frame 43 is fixedly connected to the surface of the plate 41 and located on one side of the guide rail 42. The fixed end of the stabilizing mechanism 44 is fixedly connected to one end of the support frame 43. The stabilizing end of the stabilizing mechanism 44 is coaxial with the rotation axis of the rotating part of the inspected component 60. By the support frame 43 being fixedly connected to the surface of the plate 41 and located on one side of the guide rail 42, the plate 41 can support the support frame 43, so that the support frame 43 is located in the lateral position after the bearing plate 11 enters the inspection station along the guide rail 42, and the support frame 43 is prevented from blocking the bearing plate 11 from sliding in the third direction. The stabilizing mechanism 44 is fixedly connected to one end of the support frame 43 via its fixed end. The support frame 43 supports the stabilizing mechanism 44, keeping it in the position corresponding to the inspection station. When the bearing plate 11 moves the inspected component 60 to the inspection station, the stabilizing end of the stabilizing mechanism 44 aligns with the rotating part of the inspected component 60. Since the stabilizing end of the stabilizing mechanism 44 is coaxial with the rotation axis of the rotating part of the inspected component 60, when the stabilizing mechanism 44 stabilizes the inspected component 60, its stabilizing end aligns with the inspected component 60 along the rotation axis of the rotating part. This reduces the possibility of eccentric contact or biasing of the stabilizing end relative to the rotating part, ensuring the stabilizing mechanism 44... When limiting the shaking of the tested component 60, it is not easy to generate additional off-center load on the rotation state of the rotating part (specifically, due to vibration caused by bearing clearance). During the test, the docking part 33 of the test component 30 drives the rotating part to rotate, the stop part brakes the rotating part and releases the brake, and the stabilizing mechanism 44 can stabilize or limit the tested component 60 through the stabilizing end arranged coaxially with the rotation shaft of the rotating part, so that the rotating part remains in the position corresponding to the test station during rotation and release of the brake, reducing the deviation of the tested component 60 due to braking or rotation vibration. That is, the stabilizing mechanism 44 can limit in the first direction, and can also be inserted with the rotating part to form auxiliary limiting in the second and third directions.

[0043] In this embodiment, as a preferred option, the tested component 60 includes a caliper 61, a rotary table 62, and a connecting frame 63. The caliper 61 is provided with a stop groove, and the rotary table 62 is at least partially located in the stop groove. One end of the connecting frame 63 is fixedly connected to the caliper 61 by bolts, and the other end is connected to the rotary table 62 by a bearing. The rotary table 62 has a mating groove on the surface facing the plate 41 that mates with the mating part 33. The connection between the caliper 61 and the rotary table 62 via the connecting bracket 63 is a known existing technical method, which is only cited here and will not be elaborated further. A stop groove is provided on the caliper 61, and the rotary table 62 is at least partially located within the stop groove. When the rotary table 62 is driven to rotate, the caliper 61 can form a corresponding braking position with the rotary table 62. This allows the caliper 61 to apply a stopping action through the stop groove corresponding to the outer periphery or braking point of the rotary table 62 when braking the rotary table 62. One end of the connecting bracket 63 is fixedly connected to the caliper 61 with bolts. The connecting bracket 63 provides connection and support to the caliper 61, keeping it in the stop position corresponding to the rotary table 62 and restricting the caliper 61 from rotating synchronously with the rotary table 62 when the rotary table 62 is driven to rotate. The other end of the connecting bracket 63 is connected to the rotary table 62 via a bearing. The connecting bracket 63 and the rotary table 62 can form a relatively rotatable connection, allowing the rotary table 62 to rotate relative to the connecting bracket 63 under the support of the bearing, while the connecting bracket 63 keeps the caliper 61 and the rotary table 62 in a relatively rotatable position. The installation position relationship between the turntables 62 is as follows: During the testing process, the testing component 30 drives the turntable 62 to rotate. The caliper 61 brakes and releases the turntable 62 through the stop groove. The connecting bracket 63 is fixedly connected to the caliper 61 by bolts and connected to the bearing of the turntable 62, so that the caliper 61 remains in the corresponding position during the rotation, braking and release of the turntable 62. The surface of the turntable 62 facing the plate 41 has a docking groove that mates with the docking part 33. When the second lifting mechanism 22 drives the testing component 30 to rise in the first direction, the docking part 33 can move toward the docking groove and mate with the docking groove, so that the docking part 33 and the turntable 62 form a power transmission relationship. When the docking part 33 is driven to rotate by the testing component 30, the docking part 33 can drive the turntable 62 to rotate through the docking groove, and continue to drive the turntable 62 to rotate after the caliper 61 releases the brake. The stabilizing mechanism 44 includes a third driving component 441 and a pressure block 442. The fixed end of the third driving component 441 is fixedly connected to one end of the support frame 43, and the pressure block 442 is fixedly connected to the lifting end of the third driving component 441. The connecting frame 63 has a pressure groove on its surface away from the rotary table 62 that mates with the pressure block 442. The support frame 43 supports the third driving component 441, keeping it in the position corresponding to the inspection station. The pressure block 442 is fixedly connected to the lifting end of the third driving component 441. When the lifting end of the third driving component 441 moves in the first direction, it can drive the pressure block 442 to move synchronously in the first direction, so that the pressure block 442 faces or moves away from the inspected component 60 located at the inspection station. The connecting frame 63 has a pressure groove on its surface away from the rotary table 62 that mates with the pressure block 442. When the bearing plate 11 moves the inspected component 60 to the inspection station, the third driving component 441... The component 441 can drive the pressure block 442 to move towards the connecting frame 63, so that the pressure block 442 enters the pressure groove or abuts against the groove surface. The pressure groove can limit the mating position of the pressure block 442, so that the pressure block 442 is not easily offset relative to the connecting frame 63 when it applies a stabilizing effect on the connecting frame 63, while not affecting the rotation of the rotary table 62. During the testing process, the rotary table 62 rotates under the drive of the testing component 30. The stop part brakes the rotary table 62 and releases the brake. The connecting frame 63 is used to protect... The connection between the stop and the rotary table 62 is achieved through the cooperation of the pressure block 442 and the pressure groove. The third drive component 441 can press or limit the connecting frame 63 through the pressure block 442, so that the connecting frame 63 remains in the corresponding position during the rotation, braking and release of the rotary table 62. This reduces the shaking of the connecting frame 63 caused by bearing clearance or rotational vibration. The stabilizing mechanism 44 can provide auxiliary limit for the tested component 60 and reduce the impact of the shaking of the connecting frame 63 on the drag force test results.

[0044] The first direction, second direction, and third direction do not refer to a single orientation. That is, when one of the first, second, or third directions refers to a north-south orientation, both south and north are considered the first, second, or third direction. The specific orientation can be defined according to actual usage.
