Description

Technical Field

[0001] The present application relates to the technical field of brake discs, and in particular to an all-in-one machine for measuring dynamic balance of brake discs. Background Art

[0002] At present, the performance of brake discs, as key components in the vehicle braking system, directly affects the braking effect and safety of the vehicle. In the production process of brake discs, accurate measurement technology is crucial to ensure product quality. Dynamic balancing measurement and dimensional measurement are required in the production process of brake discs. Dynamic balancing measurement is to ensure the stability of the brake disc at high-speed rotation, while dimensional measurement is to control the dimensional accuracy of the brake disc. In related technologies, the brake disc is usually first moved to a dynamic balancing machine for dynamic balancing detection, and then the brake disc is taken out of the dynamic balancing machine and moved to a measuring machine for dimensional measurement. Finally, the qualified brake disc is taken out of the measuring machine and transported to a marking machine for marking.

[0003] However, the dynamic balancing machine, measuring machine and marking machine all need to be set up separately, and there is a certain distance between the dynamic balancing machine, measuring machine and marking machine, which leads to a long time spent on transporting the brake disc and poor coordination in the production process, which easily leads to a decrease in the production efficiency of the brake disc.

[0004] Therefore, there is an urgent need for an all-in-one brake disc dynamic balance measurement machine. Summary of the invention

[0005] In order to improve production efficiency, the present application provides an all-in-one brake disc dynamic balancing measurement machine.

[0006] The present application provides a brake disc dynamic balance measurement integrated machine, which adopts the following technical solution: A brake disc dynamic balancing measurement integrated machine comprises a frame and a feeding mechanism, a dynamic balancing mechanism, a measuring mechanism, a marking mechanism and a feeding mechanism arranged on the frame in sequence, a transfer assembly is arranged on the frame, the transfer assembly is located above the feeding mechanism, the dynamic balancing mechanism, the measuring mechanism, the marking mechanism and the feeding mechanism, and the transfer assembly is used to transfer the brake disc; The feeding mechanism is used to transport the brake disc to the bottom of the transfer assembly, the dynamic balancing mechanism is used to detect the imbalance of the brake disc and correct the brake disc, the measuring mechanism is used to detect the size of the brake disc, and the marking mechanism is used to mark the brake disc.

[0007] By adopting the above technical solutions, the whole process of brake disc automation from loading to dynamic balancing detection and correction, to dimension measurement and final marking is realized. Specifically, the transfer component is located above each workstation, which can accurately transfer the brake disc on the loading mechanism to the loading mechanism, dynamic balancing mechanism, measuring mechanism, marking mechanism and unloading mechanism in sequence to ensure the smooth progress of each process. The whole process is highly integrated, which reduces manual intervention, reduces floor space, improves the coordination and reliability of the equipment, and thus significantly improves production efficiency.

[0008] Optionally, the dynamic balancing mechanism includes a first support platform, a rotation detection component and a correction component. The first support platform is arranged on the frame and is located between the feeding mechanism and the measuring mechanism. The rotation detection component and the correction component are respectively arranged on the first support platform. The rotation detection component is used to detect the imbalance of the brake disc, and the correction component is used to correct the brake disc.

[0009] By adopting the above technical solution, the first support platform in the dynamic balancing mechanism not only serves as the installation basis for each component, but also ensures the overall stability of the equipment. The rotation detection component can accurately detect the imbalance of the brake disc on the first support platform, while the correction component corrects the brake disc on the same support platform, avoiding the frequent transfer of the brake disc between different workstations and improving the accuracy and efficiency of detection and correction. This integrated design significantly improves the automation level of dynamic balancing detection and correction, reduces the equipment footprint, reduces the complexity of operation, and thus improves overall production efficiency.

[0010] Optionally, the rotation detection component includes a rotating part, a guide sleeve positioning part and a detection part, the rotating part and the detection part are respectively arranged on the first support platform, the guide sleeve positioning part is arranged on the first support platform, the guide sleeve positioning part is respectively connected to the rotating part and the detection part, the rotating part can drive the brake disc to rotate through the guide sleeve positioning part, and the detection part is used to detect the amplitude of the guide sleeve positioning part.

[0011] By adopting the above technical solution, when it is necessary to detect the imbalance of the brake disc, the brake disc is first transferred to the guide sleeve positioning component by using the transfer component, so that the guide sleeve positioning component fixes the brake disc, and then the rotating component is started, and the rotating component drives the brake disc to rotate through the guide sleeve positioning component. In this process, if the brake disc is unbalanced, the brake disc will shake during rotation, so that the brake disc drives the guide sleeve positioning component to vibrate. At this time, the detection component can accurately detect the amplitude of the guide sleeve positioning component, so as to accurately identify the imbalance point of the brake disc through calculation. This design not only improves the detection accuracy, but also ensures the efficiency and reliability of the detection process, effectively improving the automation level and work efficiency of the entire system.

[0012] Optionally, the guide sleeve positioning component includes a tensioning drive, a positioning sleeve, a rotating sleeve, a center column and an expansion sleeve, the positioning sleeve is arranged on the first support platform, the positioning sleeve is connected to the detection component, the rotating sleeve is inserted in the positioning sleeve and is coaxially arranged with the positioning sleeve, one end of the rotating sleeve is connected to the rotating component, and the other end of the rotating sleeve is coaxially arranged with a guide platform; The center column is inserted into the rotating sleeve and is slidably connected to the rotating sleeve. One end of the center column is connected to the tensioning drive member, and the other end of the center column is connected to the expansion sleeve. The expansion sleeve is coaxially sleeved on the guide platform. When the tensioning drive member pulls the expansion sleeve through the center column, the guide platform opens the expansion sleeve.

[0013] By adopting the above technical solution, when the brake disc needs to be fixed, the brake disc is first moved to the specified position so that the expansion sleeve is inserted in the center of the brake disc, and then the tensioning drive is started. The tensioning drive pulls the expansion sleeve through the center column, so that the expansion sleeve moves toward the guide platform, and the expansion sleeve is stretched by the guide platform so that the expansion sleeve is pressed against the brake disc, thereby achieving the fixation of the brake disc. At this time, the rotating component can drive the brake disc to rotate through the rotating sleeve, the center column and the expansion sleeve in turn, so as to facilitate the detection of the detection component. This design not only improves the position accuracy of the brake disc during the detection process, but also enhances the reliability of the system and avoids detection errors caused by position deviation.

[0015] By adopting the above technical solution, when the brake disc needs to be corrected, the brake disc is first clamped by the clamping component and driven to separate from the rotation detection component, and then the brake disc is milled by the milling component. During this process, the rotating component can drive the brake disc to rotate through the clamping component to adjust the angle of the brake disc, thereby facilitating the milling component to correct the imbalance of the brake disc, thereby improving the quality and consistency of the product and helping to reduce processing errors caused by vibration.

And when it is necessary to correct the imbalance of the brake disc, the clamping driver first drives the first clamping jaw to move in a direction close to the rotating detection component, so that the first clamping jaw moves to the top of the brake disc, and then the clamping driver drives the first clamping jaw and the second clamping jaw to approach each other, so as to clamp the brake disc with the first clamping jaw and the second clamping jaw. In this process, the second clamping jaw lifts the brake disc, so that the brake disc is separated from the rotating detection component, so as to correct the imbalance of the brake disc.

[0019] By adopting the above technical solution, it is possible to flexibly switch between dynamic balancing detection, dimensional measurement and flaw detection without increasing the size of the equipment. Specifically, the setting of the flaw detection mechanism allows the originally independent dynamic balancing detection and dimensional measurement functions to be replaced, thereby realizing the multifunctionality of the equipment. When it is necessary to perform flaw detection on the brake disc, first place the brake disc on the support assembly, and then use the flaw detection drive assembly to drive the brake disc to rotate, so that the flaw detection assembly can fully perform flaw detection on the brake disc, thereby ensuring the accuracy and reliability of the flaw detection process, and further improving the automation level and work efficiency of the whole machine. This design not only saves space, but also improves the adaptability and flexibility of the equipment to meet different production needs.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-9 This application is described in further detail.

[0038] The embodiment of the present application discloses an all-in-one machine for measuring dynamic balance of a brake disc.

[0039] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0040] Example 1 Reference Figure 1A brake disc dynamic balancing and measuring device includes a frame 1 and a feeding mechanism 2, a dynamic balancing mechanism 3, a measuring mechanism 4, a marking mechanism 5 and a feeding mechanism 6 which are sequentially mounted on the frame 1. A transfer assembly 11 is mounted on the frame 1. The transfer assembly 11 is located above the feeding mechanism 2, the dynamic balancing mechanism 3, the measuring mechanism 4, the marking mechanism 5 and the feeding mechanism 6. The transfer assembly 11 can accurately transfer the brake disc 7 on the feeding mechanism 2 to the feeding mechanism 2, the dynamic balancing mechanism 3, the measuring mechanism 4, the marking mechanism 5 and the feeding mechanism 6 in sequence to ensure the smooth progress of each process.

[0041] A truss 12 is installed on the frame 1, and a loading mechanism 2, a dynamic balancing mechanism 3, a measuring mechanism 4, a marking mechanism 5, and a unloading mechanism 6 are distributed along the length direction of the truss 12. The transfer assembly 11 includes four Z-axis manipulators 111, and the four Z-axis manipulators 111 are sequentially arranged along the length direction of the truss 12. In this embodiment, the Z-axis manipulator 111 can be pneumatically or electrically driven and can move freely along the length direction of the truss 12.

[0042] The hand of the Z-axis manipulator 111 can be designed into different gripping structures according to the shape and size of the brake disc 7, for example, a vacuum suction cup or a clamp is used to fix the brake disc 7 to ensure that the brake disc 7 is not damaged during the transfer process. The four Z-axis manipulators 111 are defined as manipulator A, manipulator B, manipulator C and manipulator D.

[0043] When the brake disc 7 needs to be inspected and processed, the loading mechanism 2 is first used to transport the brake disc 7 to a position close to the dynamic balancing mechanism 3, and then the robot A is used to transfer the brake disc 7 on the loading mechanism 2 to the dynamic balancing mechanism 3, so that the dynamic balancing mechanism 3 can detect the imbalance of the brake disc 7 and calibrate the brake disc 7. After the calibration is completed, the robot B transfers the brake disc 7 from the dynamic balancing mechanism 3 to the measuring mechanism 4, so that the measuring mechanism 4 can detect the size of the brake disc 7, and after the inspection is completed, the robot C transfers the brake disc 7 from the measuring mechanism 4 to the marking mechanism 5, so that the marking mechanism 5 can mark the brake disc 7. Finally, the robot D is used to transfer the brake disc 7 from the marking mechanism 5 to the unloading mechanism 6 to complete the inspection and processing of the brake disc 7.

[0044] Reference Figure 1 and Figure 2 The feeding mechanism 2 includes a base frame 21, a conveying roller set 22, a lifting assembly 23 and a stopper 24. The base frame 21 is mounted on the frame 1, and the conveying roller set 22 includes a plurality of conveying rollers, which are respectively mounted on the frame 1 and spaced apart from each other. In this embodiment, a motor is used to drive the plurality of conveying rollers to rotate synchronously, so as to facilitate the conveying of the brake disc 7.

[0045] Reference Figure 2 and Figure 3The lifting assembly 23 is located below the conveying roller group 22, and the lifting assembly 23 includes a lifting cylinder 231, a connecting plate 232, and a plurality of lifting plates 233. The lifting cylinder 231 is installed on the base frame 21, the connecting plate 232 is connected to the lifting cylinder 231, and a plurality of lifting plates 233 are respectively installed on the connecting plate 232 and are arranged parallel to each other, and a lifting plate 233 is located between two conveying rollers.

[0046] Reference Figure 1 and Figure 2 When the brake disc 7 needs to be removed from the conveying roller set 22 by the robot A, the lifting cylinder 231 (refer to Figure 3 ) works by connecting plate 232 (refer to Figure 3 ) drives the lifting plate 233 to rise, and the lifting plate 233 lifts the brake disc 7, thereby facilitating the robot A to take away the brake disc 7.

[0047] Reference Figure 2 The blocker 24 is mounted on the base frame 21, and the blocker 24 includes a lifting cylinder 241 and a blocking shaft 242. The lifting cylinder 241 is mounted on the base frame 21, and the blocking shaft 242 is connected to the lifting cylinder 241, and the lifting cylinder 241 is used to drive the blocking shaft 242 to approach or move away from the conveying roller.

[0048] Reference Figure 1 and Figure 2 When the lifting cylinder 241 drives the blocking shaft 242 to approach the conveying roller, the blocking shaft 242 can limit the brake disc 7 on the conveying roller, so that the brake disc 7 at the rear and the brake disc 7 at the front are not likely to interfere. And when the lifting cylinder 241 drives the blocking shaft 242 away from the conveying roller, the conveying roller can drive the brake disc 7 to move, so that the robot A can take away the brake disc 7.

[0049] Reference Figure 1 and Figure 4 The dynamic balancing mechanism 3 includes a first support platform 31, a rotation detection component 32 and a correction component 33. The first support platform 31 is installed on the frame 1 and is located between the feeding mechanism 2 and the measuring mechanism 4. The rotation detection component 32 and the correction component 33 are installed on the first support platform 31 respectively.

[0050] The rotation detection assembly 32 includes a rotation component (not shown in the figure), a guide sleeve positioning component 321 and a detection component (not shown in the figure). The rotation component and the detection component are respectively installed in the first support platform 31, the guide sleeve positioning component 321 is arranged on the first support platform 31, and the guide sleeve positioning component 321 is respectively connected to the rotation component and the detection component.

[0051] Reference Figure 4 and Figure 5The guide sleeve positioning component 321 includes a tensioning driving component 3211, a positioning sleeve 3212, a rotating sleeve 3213, a central column 3214 and an expansion sleeve 3215. The tensioning driving component 3211 and the positioning sleeve 3212 are respectively installed in the first support platform 31, and the positioning sleeve 3212 is connected to the detection component. The rotating sleeve 3213 is inserted in the positioning sleeve 3212 and is coaxially arranged with the positioning sleeve 3212. The bottom of the rotating sleeve 3213 is connected to the rotating component, so that the rotating component can drive the rotating sleeve 3213 and the positioning sleeve 3212 to rotate relative to each other.

[0052] The top of the rotating sleeve 3213 is fixedly connected with a guide platform 3216. In this embodiment, the guide platform 3216 is designed to be conical, and the larger end of the guide platform 3216 is arranged close to the rotating sleeve 3213.

[0053] The center column 3214 is inserted into the rotating sleeve 3213 and is slidably connected to the rotating sleeve 3213, and the center column 3214 and the rotating sleeve 3213 do not rotate relative to each other. One end of the center column 3214 is fixedly connected to the tensioning drive member 3211, and the other end of the center column 3214 is fixedly connected to the expansion sleeve 3215. The expansion sleeve 3215 is coaxially sleeved on the guide platform 3216 and is adapted to the structural design of the guide platform 3216.

[0054] In this embodiment, the tensioning driving member 3211 is a cylinder. When the brake disc 7 needs to be fixed, the brake disc 7 is first transferred to a designated position so that the expansion sleeve 3215 is inserted into the center hole of the brake disc 7. Then the tensioning driving member 3211 is started, and the tensioning driving member 3211 pulls the expansion sleeve 3215 downward through the center column 3214, so that the expansion sleeve 3215 moves toward the direction close to the guide platform 3216, so that the expansion sleeve 3215 is opened by the guide platform 3216, so that the expansion sleeve 3215 is pressed against the brake disc 7, thereby achieving the fixation of the brake disc 7.

[0055] In this embodiment, the rotating component is driven by a motor, and the rotational motion is transmitted to the rotating sleeve 3213 through a transmission belt, so that the rotating sleeve 3213 drives the center column 3214 to rotate, and the center column 3214 drives the expansion sleeve 3215 to rotate, thereby driving the brake disc 7 to rotate.

[0056] During the rotation of the brake disc 7, if the brake disc 7 is unbalanced, the brake disc 7 will shake during the rotation, and the shaking will be transmitted to the central column 3214, the rotating sleeve 3213 and the positioning sleeve 3212 through the expansion sleeve 3215, so that the positioning sleeve 3212 vibrates. At this time, the detection component can detect the amplitude of the positioning sleeve 3212, so as to accurately identify the unbalanced point of the brake disc 7 through calculation, and complete the detection of the unbalanced amount of the brake disc 7. In this embodiment, the detection component uses a sensor to detect the amplitude.

[0057] Reference Figure 4 The correction assembly 33 includes a rotating component 331, a pressing component 332 and a milling component 333. The milling component 333 is installed on the first support platform 31, the rotating component 331 is rotatably connected to the first support platform 31, and the pressing component 332 is installed on the rotating component 331.

[0058] Reference Figure 4 The rotating component 331 includes a rotating driving member (not shown in the figure) and a rotating disk 3311. The rotating driving member is installed in the first support platform 31. The rotating disk 3311 is rotatably connected to the first support platform 31 and connected to the rotating driving member. A clearance hole 3312 is coaxially provided on the rotating disk 3311 to avoid the rotation detection component 32, so that one end of the rotation detection component 32 can pass through the clearance hole 3312, thereby avoiding interference between the rotating disk 3311 and the rotation detection component 32. In this embodiment, the rotating driving member is driven by a motor, and the rotating disk 3311 is driven to rotate by a worm gear structure to accurately adjust the rotation angle of the rotating disk 3311.

[0059] There are three clamping parts 332, which are distributed around the axis of the rotating disk 3311, and the clamping parts 332 include a clamping driver 3321, a first clamping jaw 3322, and a second clamping jaw 3323. The clamping driver 3321 is installed on the rotating disk 3311, and a rotating shaft is rotatably connected to the clamping driver 3321. The first clamping jaw 3322 is installed on the rotating shaft, and the clamping driver 3321 can drive the rotating shaft to rotate and drive the rotating shaft to rise and fall, so as to drive the first clamping jaw 3322 to rotate and drive the first clamping jaw 3322 to rise and fall.

[0060] The second clamping jaw 3323 is slidably connected to the pressing driving member 3321 and is disposed near the rotating disk 3311. When the pressing driving member 3321 drives the first clamping jaw 3322 to rise and fall through the rotating shaft, the pressing driving member 3321 will synchronously drive the second clamping jaw 3323 to rise and fall, so that the first clamping jaw 3322 and the second clamping jaw 3323 are close to or away from each other.

[0061] Reference Figure 4 and Figure 5When the unbalance of the brake disc 7 needs to be detected, the clamping driver 3321 first drives the first clamping jaw 3322 to move away from the center of the rotating disk 3311, so that the first clamping jaw 3322 is not easy to interfere with the brake disc 7, so as to detect the unbalance of the brake disc 7. When the unbalance of the brake disc 7 needs to be corrected, the clamping driver 3321 first drives the first clamping jaw 3322 to move toward the center of the rotating disk 3311, so that the first clamping jaw 3322 moves to the top of the brake disc 7, and then the clamping driver 3321 drives the first clamping jaw 3322 and the second clamping jaw 3323 to approach each other, so as to clamp the brake disc 7 with the first clamping jaw 3322 and the second clamping jaw 3323. In this process, the second clamping jaw 3323 lifts the brake disc 7, so that the brake disc 7 is separated from the expansion sleeve 3215. At this time, the milling component 333 can mill the brake disc 7, so as to correct the unbalance of the brake disc 7.

[0062] It should be noted that how the clamping drive 3321 drives the rotating shaft to rotate and drives the first clamp 3322 and the second clamp 3323 to move closer to or away from each other, as well as how the specific structure of the milling component 333 is designed, are conventional technical means for those skilled in the art, and therefore will not be elaborated in detail in the embodiments of this application.

[0063] Reference Figure 1 and Figure 6 The measuring mechanism 4 includes a measuring platform 41, a driving pin group 42 and a measuring assembly 43. The measuring platform 41 is installed on the frame 1 and is located between the dynamic balancing mechanism 3 and the marking mechanism 5. A positioning platform 411 is installed on the measuring platform 41, and a receiving groove 412 is opened on the positioning platform 411.

[0064] A positioning member 413 is disposed in the receiving groove 412, and one end of the positioning member 413 extends above the positioning platform 411. When the brake disc 7 is placed on the positioning platform 411, the positioning member 413 is inserted into the center hole of the brake disc 7 and fits against the inner wall of the center hole, so that the brake disc 7 can be positioned by using the positioning member 413.

[0065] The driving pin group 42 is arranged in the receiving groove 412 and spaced apart from the positioning member 413. The driving pin group 42 includes a driving pin and a rotating platform. The rotating platform is installed in the positioning platform 411 and is coaxially arranged with the positioning member 413. In this embodiment, the rotating platform does not contact the positioning member 413.

[0066] The driving pin is mounted on the rotating platform. When the positioning member 413 positions the brake disc 7, the driving pin is inserted into the mounting hole of the brake disc 7, so that when the rotating platform rotates, the rotating platform can drive the brake disc 7 to rotate through the driving pin. In this embodiment, the rotating platform is driven to rotate by a motor.

[0067] Reference Figure 6 The measuring component 43 is installed on the measuring platform 41, and the measuring component 43 includes multiple groups of sensors. The multiple groups of sensors cooperate with each other and can respectively detect the inner diameter, thickness and flatness of the brake disc 7 during the rotation of the brake disc 7, thereby ensuring the high accuracy and reliability of the measurement results.

[0068] Reference Figure 1 and Figure 7 A placement component 13 is installed on the frame 1 , and the placement component 13 is located between the measuring mechanism 4 and the marking mechanism 5 , and the placement component 13 includes a support rod 131 and an in-place detection member 132 .

[0069] Reference Figure 7 and Figure 8 The support rod 131 is mounted on the frame 1, and a guide block 1311 is fixedly connected to the support rod 131, so as to accurately place the standard part on the support rod 131. It should be noted that the standard part refers to the brake disc 7 whose various parameters meet the standards.

[0070] Reference Figure 6 and Figure 7 In this embodiment, a relative measurement method is used to measure the brake disc 7. Therefore, before using the measuring component 43 to detect the size of the brake disc 7, the measuring component 43 needs to be calibrated to zero. Specifically, the standard part is removed from the support rod 131 and transferred to the positioning platform 411, so that the standard part is positioned by the positioning part 413, and then the driving pin is used to drive the brake disc 7 to rotate, so that the measuring component 43 can accurately measure the standard part, thereby completing the zero calibration.

[0071] Reference Figure 7 and Figure 8 The in-place detection member 132 is mounted on the support rod 131, and the in-place detection member 132 includes a suction cup rod 1321, a proximity switch 1322, and a positioning block 1323. The suction cup rod 1321 is slidably connected to the support rod 131, the proximity switch 1322 is mounted on the support rod 131 and is located below the suction cup rod 1321, and the positioning block 1323 is fixedly connected to the support rod 131.

[0072] When the standard part is placed on the support rod 131, the positioning block 1323 is inserted into the mounting hole on the standard part. At this time, the suction cup rod 1321 is forced to move toward the direction close to the proximity switch 1322 to facilitate detection by the proximity switch 1322, thereby achieving accurate monitoring of the position of the standard part, thereby ensuring that the posture of the standard part is consistent each time it is zeroed to reduce interference.

[0073] In this embodiment, a reset member (not shown in the figure) is provided between the suction cup rod 1321 and the support rod 131. The reset member may be a spring, so that after the standard part is separated from the support rod 131, the reset member can be used to push the suction cup rod 1321 to reset.

[0074] Reference Figure 1 In this embodiment, the marking mechanism 5 can use a laser marking machine or an inkjet printer to ensure that the marking information is clear and durable. The unloading mechanism 6 has the same structure as the loading mechanism 2, and also includes a base frame 21 and a conveying roller group 22, so that the unloading mechanism 6 can convey the marked brake disc 7 to a designated position to ensure smooth unloading of the brake disc 7.

[0075] An industrial control mechanism 8 is installed on the frame 1 , and the industrial control mechanism 8 is electrically connected to the feeding mechanism 2 , the dynamic balancing mechanism 3 , the measuring mechanism 4 , the marking mechanism 5 and the unloading mechanism 6 , respectively.

[0076] In this embodiment, the industrial control mechanism 8 can adopt a PLC (programmable logic controller) or an industrial computer to exchange data with various mechanisms through a communication interface, so as to monitor the working status of each mechanism in real time, automatically adjust production parameters, and improve production efficiency and stability.

[0077] The implementation principle of a brake disc dynamic balance measuring machine in the embodiment of the present application is as follows: when the brake disc 7 needs to be tested, the feeding mechanism 2 is first used to transport the brake disc 7 to be tested to a position close to the first support platform 31, and the brake disc 7 on the feeding mechanism 2 is transferred to the expansion sleeve 3215 by the manipulator A, so that the expansion sleeve 3215 is inserted into the center hole of the brake disc 7. Then the tensioning driving member 3211 is started, and the tensioning driving member 3211 pulls the expansion sleeve 3215 downward through the center column 3214, so that the guide platform 3216 opens the expansion sleeve 3215. At this time, the expansion sleeve 3215 is pressed against the inner wall of the center hole of the brake disc 7 to fix the brake disc 7. Then the rotating component is started, and the rotating component drives the brake disc 7 to rotate through the rotating sleeve 3213, the center column 3214 and the expansion sleeve 3215 in turn. In this process, the detection component can detect the imbalance of the brake disc 7 through the positioning sleeve 3212. After the detection is completed, the rotating component stops working.

[0078] Next, the clamping driving member 3321 clamps the brake disc 7 through the first clamping jaw 3322 and the second clamping jaw 3323 to separate the brake disc 7 from the expansion sleeve 3215. At this time, according to the detected imbalance, the milling component 333 mills the brake disc 7 to complete the correction.

[0079] After the calibration is completed, the robot B transfers the brake disc 7 to the positioning platform 411, so that the positioning member 413 is inserted into the center hole of the brake disc 7. At the same time, the rotating platform drives the brake disc 7 to rotate through the driving pin. At this time, the measuring component 43 detects the size of the brake disc 7. After the detection is completed, the robot C transfers the brake disc 7 from the measuring mechanism 4 to the marking mechanism 5, and the marking mechanism 5 marks the brake disc 7. Finally, the robot D transfers the brake disc 7 from the marking mechanism 5 to the unloading mechanism 6 to complete the detection and processing of the brake disc 7.

[0080] In the embodiment of the present application, by integrating multiple processes such as loading, dynamic balancing detection, dimension measurement, marking and unloading into the same device, the full process automation of the detection and correction of the brake disc 7 is realized. This process significantly improves production efficiency, reduces floor space, reduces labor costs, and improves product quality. In addition, in the embodiment of the present application, there is a certain interval between the dynamic balancing mechanism 3 and the measuring mechanism 4, so that the dynamic balancing detection and dimension measurement are not easy to interfere, thereby effectively solving the problem of mutual exclusion between dynamic balancing measurement and dimension measurement, and eliminating the adverse effect of vibration generated during the dynamic balancing detection on dimension measurement.

[0081] Example 2 Reference Figure 1 and Fig. 9 The difference between this embodiment and embodiment 1 is that the dynamic balancing mechanism 3 is replaced by a flaw detection mechanism 9.

[0082] The flaw detection mechanism 9 includes a second support platform 91, a support assembly 92, a flaw detection assembly 93 and a flaw detection drive assembly 94. The second support platform 91 is installed on the frame 1 and is located between the feeding mechanism 2 and the measuring mechanism 4, and the support assembly 92, the flaw detection assembly 93 and the flaw detection drive assembly 94 are respectively installed on the second support platform 91.

[0083] The support assembly 92 includes a central guide sleeve 921 and a support shaft 922. The central guide sleeve 921 is installed on the second support platform 91, and three support shafts 922 are provided. The three support shafts 922 are evenly distributed on the second support platform 91 around the axis of the central guide sleeve 921, and each support shaft 922 is rotatably connected to a roller 923.

[0084] When the position of the brake disc 7 needs to be fixed, the central guide sleeve 921 is inserted into the central hole of the brake disc 7, and the rollers 923 on the three support shafts 922 respectively contact the bottom surface of the brake disc 7. At this time, the rollers 923 cooperate with the central guide sleeve 921 to stably support the brake disc 7, and the setting of the rollers 923 enables the brake disc 7 to smoothly rotate around the axis of the central guide sleeve 921.

[0085] Reference Fig. 9The flaw detection drive assembly 94 includes a sliding seat 941, a driving motor 942, a driving disk 943 and a driving rod 944. The sliding seat 941 is slidably disposed on the second support platform 91, and is driven by a screw rod to drive the sliding seat 941 close to or away from the central guide sleeve 921.

[0086] The driving motor 942 is installed on the sliding seat 941, the driving disk 943 is rotatably connected to the sliding seat 941 and connected to the driving motor 942, the driving rod 944 is slidably connected to the driving disk 943, and the driving rod 944 is located at a non-center position of the driving disk 943, so that the driving motor 942 can drive the driving rod 944 to rotate around the axis of the driving disk 943 through the driving disk 943.

[0087] When it is necessary to drive the brake disc 7 to rotate, the sliding seat 941 moves to a position close to the center guide sleeve 921, so that the driving rod 944 is inserted into the mounting hole on the brake disc 7, and then the driving motor 942 is started. The driving motor 942 drives the brake disc 7 to rotate through the driving disc 943 and the driving rod 944 in turn.

[0088] The flaw detection assembly 93 includes a plurality of flaw detection sensors, which are respectively mounted on the second support platform 91 and the sliding seat 941 to detect flaws on the brake disc 7 when the brake disc 7 rotates.

[0089] The implementation principle of this embodiment is: using the flaw detection mechanism 9 to replace the dynamic balancing mechanism 3, so as to facilitate the flaw detection of the brake disc 7, timely discover potential defects, ensure that the quality of the product is more reliable, thereby realizing the multifunctionality of the equipment to meet different production needs, and further improving the adaptability and flexibility of the equipment.

[0090] Example 3 Reference Figure 1 and Fig. 9 The difference between this embodiment and embodiment 1 is that the flaw detection mechanism 9 is used to replace the measuring mechanism 4.

[0091] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
