Description

Technical Field

[0001] This utility model relates to the technical field, specifically to an inspection tool for an automotive oil pan. Background Technology

[0002] The oil pan, also known as the oil sump, is an important component of the engine. Its main function is to store lubricating oil and seal the crankcase for lubrication of various engine parts. Made of stamped thin steel sheet, it possesses a certain strength and rigidity, effectively storing and distributing lubricating oil to ensure adequate lubrication of all moving parts of the engine, thereby reducing wear and damage.

[0003] A search revealed a utility model patent in China, CN222579524U, which discloses an oil pan airtightness testing device. The device includes an oil pan with an integrally formed connecting edge at its opening, and a testing platform. In use, the oil pan to be tested is placed in a placement groove with its opening facing upwards, ensuring the pan is submerged in water. The telescopic shaft of a telescopic cylinder is then pressed down, causing a pressing plate to extend into the placement groove and press against the connecting edge of the oil pan, sealing it. An inflation device is then activated, injecting gas into the oil pan through a vent. If the tested oil pan has cracks, gas will be generated on the outer surface at the location of the crack. The above-mentioned device can quickly determine the location of damage to the oil pan, facilitating subsequent processing and improving inspection efficiency. However, it still has some shortcomings. For example, the placement groove of the device is recessed. After the oil pan is placed in the groove for inspection, although it will float upwards due to the buoyancy of the water, the oil pan also has a certain weight. Different sizes of oil pans will float differently. Some oil pans may float right at the outlet of the placement groove or inside the groove, making it inconvenient to remove them. The above-mentioned device is not convenient for assisting in pushing out the oil pan, thus making it easier for workers to remove it. Its practicality is somewhat lacking. Therefore, we propose an automotive oil pan inspection fixture. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an automotive oil pan inspection fixture to solve the problems mentioned in the background art. The placement groove is recessed; after the oil pan is placed in for inspection, although it will float due to buoyancy, the oil pan also has a certain weight. Different sizes of oil pans float differently, and some may float precisely at the outlet of the placement groove or inside the groove, making it difficult to remove. The aforementioned device does not effectively assist in ejecting the oil pan, thus hindering its practicality.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tooling for inspecting automotive oil pans, comprising a placement mechanism and a pressing and air supply mechanism, and further comprising:

[0008] A testing platform, on which a support frame is fixedly connected, a placement mechanism is installed on the testing platform, a pressing air supply mechanism is installed on the support frame, and an oil pan is placed inside the placement mechanism;

[0009] A lifting mechanism is installed on the testing platform. The lifting mechanism includes a cylinder and a mounting slot. The cylinder is fixedly connected to the bottom of the testing platform, and the mounting slot is opened on the testing platform. A motor is installed in the mounting slot, and the output end of the motor passes through the mounting slot and is fixedly connected to a threaded shaft. A lifting block is threadedly sleeved on the threaded shaft. Two connecting blocks are fixedly connected to the lifting blocks, and connecting rods are fixedly connected to the connecting blocks. Both connecting rods pass through the testing platform, and a lifting plate is fixedly connected to the connecting rods. A lifting mesh seat is detachably connected to the lifting plate for lifting out the oil pan after testing, thereby improving testing efficiency.

[0010] Preferably, two sliding grooves are fixedly connected between the cylinder and the testing platform, and a slider is slidably connected in the sliding groove, with the lifting plate fixedly connected between the two sliders.

[0011] Furthermore, two fixed cylinders are fixedly connected to the lifting plate, and a fixed rod is placed inside the fixed cylinder. The fixed rod and the fixed cylinder are detachably connected by bolts, and the lifting mesh seat is fixedly connected to the two fixed rods.

[0012] Furthermore, the cylinder body has an opening, and a protective cover is fixedly connected between the opening and the mounting groove. A maintenance plate is provided on the protective cover, and the motor is located inside the protective cover.

[0013] Furthermore, a fixed frame is fixedly connected to the testing platform, and a fixed seat is fixedly connected to the fixed frame. One end of the threaded shaft is rotatably connected to the fixed seat.

[0014] Based on the aforementioned scheme, a reinforcing frame is fixedly connected between the two fixed cylinders.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a tooling for inspecting automotive oil pans, which has the following advantages:

[0017] This automotive oil pan inspection fixture, through the cooperation of an inspection table, placement mechanism, cylinder, and pressure air supply mechanism, facilitates the placement and inspection of the oil pan. After inspection, the motor and threaded shaft work together to lift the lifting block and connecting rod, which in turn pulls the lifting plate and support mesh seat to rise, allowing the support mesh seat to fully eject the oil pan. This makes it easy for workers to remove and replace the oil pan, saving manpower and improving inspection efficiency and practicality. The bolts, fixing rods, and fixing cylinders allow for easy replacement of the support mesh groove specifications, making it suitable for ejecting oil pans of different sizes.
