Description

Technical Field

[0001] The present invention relates to the field of detection devices, in particular to an automatic eddy current and ultrasonic combined detection device and a detection method for an outer ball cage rod. Background Art

[0002] The external ball cage rod often refers to the drive shaft connected to the external constant velocity joint in an automotive transmission system, also known as the external ball cage drive shaft. After production, external ball cage rods are subject to long-term exposure to high torque, complex loads, and harsh environments (such as mud, water, and sand and gravel erosion). These rods are prone to surface cracks, wear, and internal material defects. These defects can lead to transmission failure and even safety accidents. Therefore, they must undergo rigorous quality inspection before shipment. Currently, external ball cage rod inspection primarily relies on manual visual inspection, magnetic particle inspection, or a single nondestructive testing technique (such as eddy current testing or ultrasonic testing). However, these methods have the following limitations: manual inspection is inefficient, relies on experience, is prone to missed detections, and is difficult to automate in batches. Magnetic particle inspection is only suitable for surface defects, but cannot detect internal material defects (such as pores and inclusions) and requires workpiece cleaning, making the process cumbersome. Eddy current testing is suitable for surface and near-surface defects (such as cracks and pits), but is insensitive to deeper internal defects. Most inspection devices only support a single technique, requiring multiple setups, which affects inspection efficiency and consistency.

[0003] In view of this, it is necessary to provide an automatic eddy current and ultrasonic combined detection device and detection method for an outer ball cage rod. Summary of the Invention

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] like Figure 1As shown, the first embodiment provided by the present application is an automatic eddy current ultrasonic combined detection device for an outer ball cage rod, comprising a frame 1, and also comprising a feeding conveyor line 2 arranged on one side of the frame 1, a discharging conveyor line 3 arranged on the other side of the frame 1, a turntable 4 arranged on the frame 1, a divider arranged on the frame 1 for driving the turntable 4 to rotate, a plurality of circumferentially rotating jigs 5 arranged on the turntable 4, a driving mechanism 6 arranged on the frame 1 for driving the jig 5 to rotate, an eddy current detection mechanism 7 arranged on the frame 1 for detecting the product 100 on the rotating jig 5, an ultrasonic detection mechanism 8 arranged on the frame 1, a No. 1 transfer mechanism 9 arranged on the frame 1 for transferring the product 100 from the feeding conveyor line 2 to the jig 5, a No. 2 transfer mechanism 10 arranged on the frame 1 for transferring the product 100 from the jig 5 to the ultrasonic detection mechanism 8, and a No. 3 transfer mechanism 11 for transferring the product 100 from the ultrasonic detection mechanism 8 to the discharging conveyor line 3.

[0030] In actual use, the No. 1 transfer mechanism 9 transfers the product 100 from the feed conveyor line 2 to the jig 5, and then the turntable 4 rotates under the drive of the indexer. After the indexer rotates one angle, the driving mechanism 6 drives the jig 5 to rotate so that the product 100 rotates synchronously. During the rotation process, the eddy current detection mechanism 7 scans the detection surface of the product 100, and then the No. 2 transfer mechanism 10 transfers the product 100 from the jig 5 to the ultrasonic detection mechanism 8 for detection, and then the No. 3 transfer mechanism 11 receives the product 100 after ultrasonic detection and transfers the product 100 to the discharge conveyor line 3.

[0031] In the above design, it is possible to detect the surface defects and internal defects of the outer ball cage rod, thereby improving the inspection efficiency of the product 100.

[0032] Specifically: Figure 2 and Figure 3 As shown, the fixture 5 includes a No. 1 plate 51 fixedly set on the turntable 4, a No. 1 column 52 fixedly set on the lower end surface of the fixed plate, a No. 2 plate 53 connecting several No. 1 columns 52, a No. 1 flange 54 set on the No. 1 plate 51, a No. 2 flange 55 set on the No. 2 plate 53, a No. 1 ball bearing set in the No. 1 flange 54, a No. 2 ball bearing set in the No. 2 flange 55, a No. 1 shaft 56 sleeved on the inner rings of the No. 1 ball bearing and the No. 2 ball bearing, a supporting and positioning seat 57 fixedly set on the upper end of the No. 1 shaft 56, a limiting nut 58 set at the lower end of the No. 1 shaft 56 and a No. 1 friction wheel 59 coaxially set on the No. 1 shaft 56.

[0033] In actual use, the No. 1 friction wheel 59 drives the No. 1 shaft 56 to rotate synchronously under the drive of the driving mechanism 6, so that when the No. 1 shaft 56 rotates, it drives the supporting and positioning seat 57 to rotate, thereby realizing the rotation of the product 100 in the supporting and positioning seat 57.

[0034] In the above design, the structural design and specific implementation of the fixture 5 can effectively realize the rotation of the product 100, thereby ensuring that the surface defects of the product 100 are detected while the eddy current detection mechanism 7 is fixed.

[0036] During actual use, the transverse plate 603 is driven by the No. 1 cylinder 602 to move horizontally toward the side of the fixture 5. After the No. 1 friction wheel 59 and the No. 2 friction wheel 610 are in contact but before the stroke of the No. 1 cylinder 602 is completed, the slider 606 moves along the guide column 605 to the side away from the fixture 5, so that the No. 1 spring 614 is compressed; when the stroke of the No. 1 cylinder 602 is completed, the No. 1 motor drives the active shaft to rotate, and under the transmission of the synchronous belt 613, the driven pulley 612 and the active pulley 611 rotate synchronously, driving the shaft and the No. 2 friction wheel 610 to rotate, and the friction between the No. 2 friction wheel 610 and the No. 1 friction wheel 59 is used to make the No. 1 friction wheel 59 rotate synchronously.

[0037] In the above design, the driving mechanism 6 has a simple and compact structure, which can achieve stable driving of the No. 1 friction wheel 59, thereby achieving stable and uniform rotation of the product 100 in the fixture 5, and improving the accuracy of eddy current detection on the outer surface of the product 100.
