[0030] The drive detection assembly 3 is arranged on the lifting device 4, and the drive detection assembly 3 is used to dock the flange drive disk 6 and the tooling disk 7 to the set position; the drive detection assembly includes a positioning slide 18, and the positioning slide 18 is connected to the lifting device. At the same time, the positioning slide 18 is also provided with a spindle support and a drive motor connecting seat, the spindle support is used to assemble the spindle, and the drive motor connecting seat is used to assemble the fourth drive motor 12; the fourth drive motor 12 in the drive detection assembly 3 rotates after being energized, driving the torque sensor 13 and connecting the spindle 15 through the coupling 14 to drive the workpiece 8 to rotate, and the rotational torque, ABS and speed ratio of the workpiece 8 are detected;

[0031] The first drive motor 9 in the lifting device 4 drives the reducer 16 to rotate to drive the screw to rotate. The connecting plate 17 (nut) on the screw is connected to the positioning slide 18 in the drive detection component 3. The first drive 9 controls the forward position of the drive detection component 3. In this way, the displacement accuracy of the drive detection component 3 is greatly improved by using the first drive motor 9 to drive, and the stable docking with the workpiece 9 can be accurately ensured;

[0032] The support assembly 5 is a bilaterally symmetrical structure, comprising a left support frame 19 and a right support frame; both support frames are connected to a connecting rod 20, the upper portion of which is connected to a support pad 21 to support the workpiece 8. One end of the connecting rod 20 is hingedly connected to the support frame, and the other end drives the connecting rod 20 to adjust the angle of the workpiece 8 through the up and down movement of a single air chamber 22;

[0033] In the above embodiment, the driving detection component 3 is used to provide the workpiece 8 to be inspected with simulated vehicle power, and the fourth driving motor 12 is used to drive the workpiece to rotate, simulating the actual condition of the drive assembly on the whole vehicle, and cooperating with various components to detect various parameters of the workpiece 8, so that it is possible to accurately judge whether the product is qualified according to the process requirements, and accurately detect the problem of unqualified workpieces, thereby improving the quality control of the workpiece before leaving the factory and ensuring the qualified rate of the product leaving the factory.

[0034] To facilitate understanding of the detection device provided by the embodiments of the present invention, it is described in detail below with reference to specific drawings and embodiments.

[0035] Continue to refer Figure 1 , Figure 1The structure diagram of an automatic docking and running-in test device for a vehicle axle assembly provided by an embodiment of the present invention is shown. The automatic docking and running-in test device for a vehicle axle assembly in this embodiment mainly comprises a frame 1, a frame 2, a drive detection assembly 3, a lifting device 4, and a support assembly 5.

[0036] When inspecting workpiece 8 using drive detection assembly 3, support assembly 5 is first adjusted to the desired position for workpiece 8 and placed on the run-in test device. Lifting device 4 then lifts drive detection assembly 3 to the desired position. First drive motor 9 and reducer 16 then drive detection assembly 3 forward and dock with workpiece 8. The fourth drive motor then rotates to simulate the vehicle's complete state, allowing various data to be inspected.

[0037] Among them, the structure of rack 1 is as follows Figure 1 As shown, it adopts a welded frame structure and connects frame 1 to frame 2 2, effectively ensuring the overall rigidity of the equipment. In the specific setting, frame 1 is provided with a linear guide rail 23, which is located in front of frame 1. The linear guide rail 15 is connected to the support assembly 5, which effectively ensures the stability of the equipment.

[0038] For reference Figure 1 and Figure 2 The drive detection assembly 3 for docking the workpiece 8 includes a fourth drive motor 12, which is connected to a drive motor mounting bracket 24 and a magnetic powder clutch 25. The torque sensor 13 and the main shaft 15 are connected via a coupling 14. The universal limit sleeve 26 is also fixed on the main shaft 15 and connected to the flange drive plate 6 and the tooling plate 7 to dock the workpiece 8. Product detection is achieved through the rotation of the motor;

[0039] During specific use, the fourth drive motor 12 drives the magnetic powder clutch 25, the torque sensor 13, the main shaft and other parts to rotate, and the workpiece is docked by slow rotation at the beginning. After the tooling plate 7 is completely in contact with the flange surface of the workpiece 8, the positioning mounting plate 27 is retracted by (a pneumatic cylinder or a hydraulic cylinder) to completely separate the support guide wheel 28 from the workpiece 8. Then, the support slide 29 is retracted by (a pneumatic cylinder or a hydraulic cylinder), so that the workpiece 8 can be rotated and the product can be inspected.

[0040] refer to Figure 1 、 Figure 2 and Figure 3 The lifting device 4 is fixed to the slide base 33 by the guide optical axis 30, connected to the linear guide rail 32, and drives the detection component 3 to move forward and backward through the first drive motor 9 and the reducer 16, and then guides the optical axis 30 up and down to achieve the lifting effect;

[0041] In specific use, the lifting device 4 needs to be used in conjunction with the drive detection component 3. It is driven by the guide optical axis 30 (cylinder, motor or oil cylinder), and the lifting slide base 31 is compatible with the height differences of different products. It cooperates with the first drive motor 9 and the reducer 16 to drive the drive detection component 3 to move back and forth, and is compatible with the length differences of different products.

[0042] refer to Figure 1 and Figure 4 The left support frame 19 of the support assembly 5 (the support assembly 5 is a symmetrical two-piece assembly) is connected to the linear guide rail 23, and is further connected to the connecting rod 20 and the support pad 21 to stably support the product 8. The second drive motor 10 and the third drive motor 11 drive the symmetrical left and right support frames to move left and right, and the cylinder is used for precise positioning to meet the different spacing requirements of different products.

[0043] When in use, the first drive motor 10 and the third drive motor 11 are in the original position, and the linear guide rail 23 is used to slide and drive the support frame to move. The motor determines the position where the support frame stays to ensure the position is accurate. The cylinder is connected to the pressure pad 31, and the extension of the cylinder limits the position of the support frame to ensure that the support is stable in a certain position.

[0044] The above is a specific use of a single mechanism. As a preferred technical solution, this embodiment provides an automatic docking and running-in test device for an axle assembly. The control device can control all the above mechanisms as a whole, effectively combining the above mechanisms to achieve fast and efficient operation.

[0045] The control device controls the effective transmission coordination of the driving detection component 3, the lifting device 4 and the supporting component 5, thereby improving the automation level of the entire device.

[0046] During specific use, first: control the second drive motor 10 and the third drive motor 11 to drive the support assembly 5 (left-right symmetrical) to move to the set position and control the cylinder to lock the workpiece; second: control the slide base 33 in the lifting device 4 to lift the drive detection assembly 3 to the set position; third: control the first drive motor 9 and the reducer to connect the positioning slide 18 to move forward to the set position; fourth: place the workpiece 8 on the equipment; fifth: control the fourth motor to rotate slowly to dock the workpiece 8. After the docking is completed, it drives the workpiece 8 to rotate, and the torque sensor 13 is used to detect the rotational torque of the product. While rotating, the ABS, vibration and other functions can also be detected.

[0047] More preferably, the system further includes an alarm device; if any of the above actions fails, the workpiece 8 is deemed unqualified, thereby improving the detection effect of the workpiece 8. The control device records the torque, ABS, vibration and other information of the qualified product 8 on the device, facilitating data review and traceability of the product 8 in the future;

[0048] In addition, a display device is included for displaying the aforementioned torque and other data, and displaying the torque value and rotation curve of the inspected workpiece 8, so that the staff can observe the inspection results intuitively.

[0049] The control device automatically draws a torque curve and displays the torque figures through the interface, and compares it with the set torque equivalent range, and prompts the qualified and unqualified windows in the interface.

[0050] After the detection process is completed, the drive detection component 3 connected to the workpiece 8 is first separated from the workpiece, and the workpiece 8 is manually lifted away. The first drive motor drives the drive detection component 3 back to its original position; the lifting device 4 moves downward to its original position, and the second drive motor 10 and the third drive motor 11 respectively drive the left and right symmetrical parts of the support component 5 back to their original positions.

[0051] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
