Description

Technical Field

[0001] This utility model relates to the technical field of electric drive housing testing equipment, specifically to an electric drive housing testing machine. Background Technology

[0002] To ensure the assembly quality of automotive electric axle assemblies, the assembly process must ensure that the preload stiffness is within the specified value and that the bearing preload is in the optimal state. As a traditional and applicable method, most vehicle models achieve these assembly process requirements by adding adjusting shims. Currently, many manufacturers on domestic automotive production lines still use dedicated equipment for measurement. This inevitably leads to the requirement of producing multiple products on a single production line. If the measured dimensions, diameter, or position of the product changes, but the equipment is dedicated and most equipment cannot meet the measurement requirements of multiple products, additional equipment is needed, resulting in increased costs and a larger space requirement.

The bottom of the lifting bracket 4-1 and the lifting and positioning plate 4-3 are both located on a guide linear bearing structure 4-4 for limiting the position.

[0025] The specific implementation steps are as follows:

[0026] Material loading and transfer: The operator places the electric drive axle housing 8 to be tested on the positioning locking plate 3-2 and locks it. The positioning locking plate 3-2 moves along the limit frame 3-1 to transfer the electric drive axle housing 8 to the measurement station below the frame structure 2.

[0027] Lifting and positioning: The lifting electric cylinder 4-2 is started, driving the lifting positioning plate 4-3 to rise. The positioning pin at the top of the lifting positioning plate 4-3 is inserted into the positioning hole at the bottom of the positioning locking plate 3-2, which drives the positioning locking plate 3-2 and the electric drive axle housing 8 to rise synchronously until the positioning hole at the top of the electric drive axle housing 8 is matched and engaged with the housing positioning pin 5-6 of the product positioning clamping assembly structure 5.

[0028] Clamping and fixing: The clamping cylinder 5-2 of the product positioning clamping component structure 5 is activated, the piston rod extends, and the electric drive axle housing 8 is clamped and fixed through the elastic clamping block; at the same time, the automatic docking plug 5-3 connects to the detection interface of the electric drive axle housing 8 to collect basic information such as product model.

[0029] Precise Measurement: The measurement component structure 6 is activated, and the X-axis drive rail 6-1 and Y-axis drive rail 6-2 work together to move the measuring slide 6-4 above the first bearing chamber measurement position. The Z-axis drive rail 6-3 drives the measuring slide 6-4 to descend, and the measurement calibration rod 6-5 contacts the end face of the bearing chamber to determine the measurement starting point. The displacement sensor 6-6 is activated to collect dimensional data such as the bearing chamber diameter. After the first bearing chamber measurement is completed, the XYZ axes work together to move the measuring slide 6-4 to the second bearing chamber measurement position. The above measurement steps are repeated until the measurement of all key parts is completed.

[0030] Material unloading and transfer: After the measurement is completed, the piston rod of the clamping cylinder 5-2 retracts, the lifting electric cylinder 4-2 drives the lifting positioning plate 4-3 to descend, and the positioning locking plate 3-2 falls back into the limiting slide groove of the transfer structure 3; the transfer structure 3 drives the positioning locking plate 3-2 to move, and transfers the tested electric drive axle housing 8 to the unloading station.

[0031] Accuracy calibration: Every 24 hours of equipment operation, the calibration component structure 7 is activated, and the telescopic cylinder 7-3 drives the slide table 7-4 to move along the linear slide rail 7-2 to below the measuring component structure 6; the measuring component structure 6 measures the calibration component structure 7-5, compares the measurement data with the standard dimensions, and ensures the accuracy of subsequent measurements.
