Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically a multi-station new energy gearbox housing steam and water dual testing device. Background Technology

[0002] The multi-station air-water dual-inspection device for new energy vehicle transmission housings is a specialized piece of equipment used for quality inspection of transmission housings in the field of new energy vehicle component testing. This device uses both air and water testing methods to simultaneously perform critical performance tests, such as sealing, on new energy vehicle transmission housings at multiple stations, determining whether there are any leakage issues. This ensures the assembly quality and operational safety of new energy vehicle transmissions and is suitable for mass production testing scenarios of new energy vehicle transmission housings.

[0003] Traditional multi-station air-water dual-inspection devices for new energy vehicle transmission housings have significant shortcomings in terms of the flexibility and ease of replacement of the air testing devices. Most devices use a single air testing unit, inspecting transmission housings one by one. Furthermore, their fixed structure cannot flexibly adapt to air testing units with varying numbers of connecting pipes. When testing requirements change, the entire testing unit must be replaced, increasing equipment costs and adjustment cycles. In addition, some devices lack effective limiting and guiding structures, making it easy for the air testing unit to shift during installation or replacement, leading to inaccurate alignment with the transmission housing, affecting testing accuracy, and potentially damaging the air testing unit or housing due to misalignment. This makes it difficult to meet the diverse and high-efficiency testing needs of new energy vehicle transmission housings. Therefore, we propose a multi-station air-water dual-inspection device for new energy vehicle transmission housings. Summary of the Invention

[0004] One of the technical problems this application aims to solve is that existing testing devices have limited testing capabilities, low testing efficiency, and use fixed mechanisms, making it difficult to flexibly adapt to air testing devices with different numbers of connecting pipes, thus failing to meet the diverse and high-efficiency testing needs of new energy gearbox housings.

[0005] To address the aforementioned technical problems, this application provides a multi-station new energy vehicle gearbox housing dual-inspection device for steam and water, comprising a control box. A display is fixedly connected to one outer wall of the control box, and control buttons are fixedly connected to one outer wall of the control box. A limit block is fixedly connected to the lower center of the control box. Multiple mounting slots are provided on both outer walls of the limit block, and multiple snap-fit ​​mechanisms are provided on both outer walls of the limit block. A gas detection device is movably connected to one side of the inner wall of the limit block. A data transmission device is provided in the middle of the upper outer wall of the gas detection device. Multiple slots are provided on both outer walls of the gas detection device, and multiple connecting pipes are connected to both outer walls of the lower end of the gas detection device.

[0006] In some embodiments, the snap-fit ​​mechanism includes a housing, a limiting groove is formed on one side of the housing, a rotating rod is movably connected to the outer wall of one side of the housing, a protrusion is fixedly connected to one side of the rotating rod, a pin is movably connected to one side of the inner wall of the housing, a groove is formed on the outer wall of one side of the pin, a limiting member is provided on the side of the pin away from the groove, and a return spring is movably connected to the outer wall of one side of the pin.

[0007] In some embodiments, a fixing rod is fixedly connected to one side of the lower end of the control box, a first carrying plate is fixedly connected to the lower end of the fixing rod, a first cylinder is fixedly connected to the middle of the outer wall of the upper side of the first carrying plate, a slide rail is fixedly connected to the outer wall of the upper side of the first carrying plate, a movable plate is movably connected to the outer wall of the upper end of the slide rail, a locking block is fixedly connected to the outer wall of the upper end of the movable plate, and a partition plate is movably connected to the outer wall of the upper side of the movable plate.

[0008] In some embodiments, a bracket is fixedly connected to the lower side wall of the control box, a second cylinder is fixedly connected to one side of the inner wall of the bracket, a second carrying plate is fixedly connected to the lower end of the second cylinder, a water tank is fixedly connected to the upper outer wall of the second carrying plate, a limit rod is fixedly connected to one side of the lower end of the control box, a box body is fixedly connected to the lower end of the limit rod, and the control box is fixedly connected to the box body through the bracket.

[0009] In some embodiments, a pin provided on one side of the inner wall of the housing is connected to a slot opened on the side wall of the gas detector.

[0010] In some embodiments, the partition plate and the movable plate are engaged by a locking block.

[0011] In some embodiments, the limiting member provided on the side wall of the pin is correspondingly connected to the limiting groove opened on one side of the housing.

[0012] In some embodiments, a protrusion on one side of the rotating rod is connected to a groove on one side of the pin.

[0013] This utility model has at least the following beneficial effects: In use, this invention significantly optimizes the assembly and disassembly process of the gas detector by employing a quick-fixing structure comprised of a snap-fit ​​mechanism, a limiting block, and a locking groove, allowing for flexible adaptation and convenient replacement of the gas detector. The rotating rod of the snap-fit ​​mechanism engages the protrusion with the groove of the pin. When the protrusion presses against the raised part of the groove, the pin compresses the return spring and extends out of the housing, engaging with the locking groove of the gas detector for secure fixation. Reverse rotation of the rod aligns the protrusion with the recessed part of the groove, and the return spring pushes the pin back to its original position, allowing for quick removal of the gas detector. This structure not only ensures that the gas detector does not shift during testing but also supports rapid replacement of gas detectors with different numbers of connecting pipes to meet various testing needs. Furthermore, the cooperation between the limiting component and the limiting groove ensures that the pin does not shift during extension and retraction, further enhancing the convenience and stability of gas detector replacement and indirectly improving testing efficiency. In use, this invention achieves high efficiency and batch processing capabilities for the testing operation. The coordination of the first cylinder, movable plate, slide rail, and partition plate enables batch loading and testing of gearbox housings. The first cylinder drives the movable plate to slide along the slide rail, automatically completing loading (sending the partition plate to the testing position) and unloading (removing the tested partition plate), eliminating the need for manual handling. The multiple cavities within the partition plate can simultaneously accommodate multiple gearbox housings. Combined with the multi-connection pipe design of the air testing device, batch air testing can be achieved, significantly shortening the testing time per cycle. Simultaneously, the data transmission device of the air testing device transmits the testing data to the control box in real time, avoiding errors from manual recording and further improving testing efficiency and data accuracy.

The groove 66, the protrusion 64 on one side of the rotating rod 63, and the groove 66 on one side of the pin 65 are connected to each other. The pin 65 is provided with a limiting member 67 on the side away from the groove 66. The limiting member 67 on the side wall of the pin 65 is connected to the limiting groove 62 on one side of the housing 61. A return spring 68 is movably connected to the outer wall of one side of the pin 65. A gas detection device 7 is movably connected to the inner wall of the limiting block 4. A data transmission device 8 is provided in the middle of the upper outer wall of the gas detection device 7. Multiple slots 9 are provided on both outer walls of the gas detection device 7.

Multiple connecting pipes 10 are connected to both outer walls of the lower end of the gas detection device 7.

[0018] In this embodiment, a control box 1 is designed, with a display 2 and control buttons 3 on one side.

Multiple locking mechanisms 6 are provided on both sides of the limit block 4 via mounting grooves 5. These locking mechanisms 6 can be connected to multiple slots 9 on the side wall of the air detection device 7, thus fixing the air detection device 7.
