Description

Technical Field

[0001] This utility model belongs to the field of direct drive starter technology, and specifically relates to a heavy-duty direct drive starter housing sealing test device. Background Technology

[0002] A direct-drive starter is a special motor design that directly drives the load without intermediate transmission devices (such as belts, gears, etc.). The application of this technology makes the system more efficient and quieter, and reduces maintenance requirements. During the production of the direct-drive starter housing, its sealing performance needs to be tested, so a testing device is required. Existing detection devices typically employ ultrasonic or liquid detection. When gas passes through a leak, it generates eddies and emits signals in the ultrasonic band. Ultrasonic detectors can detect high-frequency ultrasonic waves while shielding low-frequency or audible sound waves, converting the ultrasonic signal into audible sound waves and quantifying and numerically representing the signal magnitude. This allows them to sense and detect various types of gas leaks, thereby determining the sealing condition. However, practical applications present several problems. For instance, during casing inspection, after the front of the casing is inspected, workers need to move to other surfaces to be inspected, or they need to move around to change their own external components. This increases the workload. To address these issues, we propose a heavy-duty direct-drive starter casing sealing detection device. Utility Model Content

[0024] Furthermore, limiting grooves are provided on both sides of the bottom of the inner cavity of the placement plate 12. The bottom of the sliding plate 17 is slidably connected to the inner cavity of the limiting groove. The limiting groove improves the sliding stability of the sliding plate 17.

[0025] Furthermore, support columns are welded around the bottom of the fixed base 1, and anti-slip pads are glued to the bottom of the support columns, which facilitates the support of the fixed base 1.

[0026] Furthermore, mounting blocks are welded to both ends of the ultrasonic detector body 5, and the surface of the mounting blocks is connected to the surface of the support plate 3 by mounting bolts. The mounting blocks and mounting bolts facilitate the assembly and disassembly of the ultrasonic detector body 5.

[0027] Example 2: refer to Figure 1 and Figure 2 A heavy-duty direct-drive starter housing sealing test device includes a support plate 3 welded to the left side of the top of the fixed base 1, a housing 9 welded to the top of the inner side of the support plate 3, an electric push rod 8 bolted to the top of the inner cavity of the housing 9, a push plate 7 bolted to the bottom of the electric push rod 8, and the surface of the push plate 7 being bolted to the back of the test probe 10.

[0030] Brief description of the usage process: The user places the housing to be tested on the surface of the placement tray 12. Then, the user tightens the locking bolt 4. The locking bolt 4 rotates within the cavities of the nut 15 and the bearing body 16. Since the threads on the surface of the locking bolt 4 and the threads in the cavity of the nut 15 are threadedly connected, the rotation of the locking bolt 4 allows it to move. This movement of the locking bolt 4 pushes the sliding plate 17 to move, which in turn moves the connecting rod 18. The connecting rod 18 then moves the limiting plate 11, which in turn limits and fixes the housing placed on the surface of the placement tray 12. The user then starts the ultrasonic detector body 5 and the detection probe 10 simultaneously via an external controller. The ultrasonic detector body 5 facilitates the movement of the push plate 7, which in turn moves the detection probe 10. Simultaneously, the ultrasonic detector body 5 can detect the casing. When it is necessary to detect other surfaces of the casing, the user starts the servo motor 14 via the external controller. The servo motor 14 facilitates the rotation of the rotating rod 13, which in turn rotates the placement plate 12. The placement plate 12 then rotates the casing, effectively adjusting the surface of the casing to be detected and improving detection efficiency.
