Description

Technical Field

[0001] This utility model belongs to the field of oil cooler testing technology, specifically relating to an oil cooler shell testing device. Background Technology

[0002] In the automotive industry, oil coolers are critical heat exchange components. Their stability and reliability are crucial for the normal operation of important systems such as car engines. The corrosion resistance of the oil cooler housing is one of the key indicators of its quality. During actual operation, oil coolers come into contact with various corrosive substances, such as the chemical components in the coolant, moisture, and impurities in the external environment. If the oil cooler housing has poor corrosion resistance, it is highly susceptible to corrosion damage during use, affecting its normal function and even causing malfunctions in the entire vehicle system, leading to safety hazards. To ensure sufficient corrosion resistance, rigorous corrosion resistance testing is required during the manufacturing process. Currently, there are spray testing devices on the market for testing the corrosion resistance of oil cooler housings. These devices mainly consist of spray pipes and frames. Their working principle is to spray corrosive liquid onto the surface of the oil cooler housing through the spray pipes, simulating the corrosion conditions in the actual use environment, thereby testing the corrosion resistance performance of the oil cooler housing.

[0003] However, traditional spray testing devices for the corrosion resistance of oil cooler shells have revealed many problems in actual use: on the one hand, the height of the spray structure is usually relatively fixed. This fixed design makes it impossible for the device to be adjusted vertically according to oil cooler shells of different sizes, limiting the flexibility of the device and failing to meet diverse testing needs; on the other hand, traditional testing devices do not have a structure designed to quickly limit the position of the oil cooler shell when it is placed upright. During corrosion resistance testing, in order to ensure that the corrosive liquid is sprayed evenly onto all surfaces of the oil cooler shell, it is usually necessary to place the oil cooler shell upright. However, in actual operation, due to the lack of an effective limiting structure, the oil cooler shell is prone to shaking, tilting, or even falling over when placed upright. In summary, existing spray testing devices for the corrosion resistance of oil cooler shells have significant deficiencies in terms of spray structure height adjustment and oil cooler shell vertical positioning limitation, and cannot meet the diverse, accurate, and safe requirements for corrosion resistance testing of oil cooler shells in actual production. Therefore, this utility model proposes an oil cooler shell testing device. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example

[0020] Please see Figures 1 to 3 This is an embodiment of the present utility model, which provides the following technical solution: an oil cooler housing testing device, comprising...

[0021] 1. Base; 2. Placement platform fixed at the top center of base 1; 4. Oil cooler housing standing at the top center of placement platform 2; 5. Two quick-release structures set on the top of placement platform 2 to press and limit the oil cooler housing 4, ensuring the stability of oil cooler housing 4 during subsequent corrosion spraying tests.

[0022] The system includes a U-shaped spray pipe 6 mounted on the placement platform 2 and the oil cooler housing 4, multiple nozzles 61 located inside the U-shaped spray pipe 6 facing the oil cooler housing 4, and an inlet hose 62 located at the top of the U-shaped spray pipe 6 and connected to an external liquid pump. The external liquid pump can deliver the corrosive liquid from the external corrosive liquid storage tank into the U-shaped spray pipe 6 through the inlet hose 62, and spray it onto the surface of the oil cooler housing 4 through the nozzles 61 to conduct a corrosion resistance spray test on the oil cooler housing 4.

[0023] Two side frames 3 are symmetrically fixed to the top of the base 1. Side base blocks 63 are fixed on both sides of the U-shaped spray pipe 6. An adjustment mechanism 7 is provided between the side base blocks 63 and the side frames 3 for subsequent flexible adjustment of the height of the U-shaped spray pipe 6.

[0024] In this embodiment, preferably, the quick-release limiting structure 5 includes a vertical plate 51 fixed to the top surface of the placement platform 2, a movable rod 52 that moves laterally through the vertical plate 51, an arc-shaped limiting and clamping block 54 fixed to one end of the movable rod 52 and in close contact with the oil cooler housing 4, a strip-shaped wax block 55 rotatably installed at the other end of the movable rod 52, and a spring 53 sleeved on the surface of the movable rod 52 and located between the arc-shaped limiting and clamping block 54 and the vertical plate 51. Under the clamping action of the spring 53, the arc-shaped limiting and clamping block 54 can stably clamp and limit the oil cooler housing 4 during daily use, ensuring the stability of the oil cooler housing 4 when placed upright.

[0025] In this embodiment, preferably, one end of the spring 53 abuts against the surface of the arc-shaped limiting block 54, and the other end of the spring 53 abuts against the side of the upright plate 51.

[0026] In this embodiment, preferably, a shaft 56 is fixed to the other end surface of the movable rod 52, and one end of the strip-shaped wax block 55 is rotatably sleeved on the shaft 56, so that the strip-shaped wax block 55 can be smoothly rotatably connected to the movable rod 52.

[0027] In this embodiment, preferably, the quick-release structure 5 further includes a limiting groove 57 formed on the surface of the edge of the placement platform 2 for the strip-shaped wax block 55 to be pulled sideways and screwed into. When the operator needs to quickly release the restriction on the oil cooler housing 4, they only need to pull the strip-shaped wax block 55 sideways, causing the movable rod 52 to pull the arc-shaped limiting block 54, which compresses the spring 53 and moves the arc-shaped limiting block 54 away from the oil cooler housing 4 until the strip-shaped wax block 55 is pulled sideways to the placement platform 2. On one side, the strip-shaped wax block 55 can be rotated 180 degrees around the shaft 56 so that the bottom end of the strip-shaped wax block 55 is aligned with the limiting groove 57. Then, the strip-shaped wax block 55 is released, so that the bottom end of the strip-shaped wax block 55 is inserted into the limiting groove 57. This supports and limits the movable rod 52 and the arc-shaped limiting block 54 in the side-pulled state, preventing the arc-shaped limiting block 54 from rebounding. This frees up the operator's hands and makes it convenient for the operator to quickly pick up and put away the oil cooler housing 4.

[0028] In this embodiment, preferably, the adjustment mechanism 7 includes a threaded rod 71 welded and fixed to the side of the side base block 63, a strip-shaped threaded rod slide 72 opened on the surface of the side frame 3 for the threaded rod 71 to pass through and move up and down, and a locking nut 73 sleeved on the end surface of the threaded rod 71. If the height of the U-shaped spray pipe 6 needs to be adjusted later, simply rotate the locking nut 73 counterclockwise to loosen it, release the restriction on the threaded rod 71 and the side base block 63, and the U-shaped spray pipe 6 can slide up and down between the two side frames 3 to make adaptive height adjustment. When the appropriate height is adjusted, simply tighten the locking nut 73 clockwise, which makes the adjustment very convenient.

[0029] In this embodiment, preferably, the locking nut 73 is threadedly connected to the threaded rod 71.

[0030] In this embodiment, preferably, the top surface of the base 1 is provided with an annular waste liquid tank 11 around the placement platform 2, and the right side of the base 1 is provided with a drain pipe 12 communicating with the annular waste liquid tank 11, so that the corrosive liquid sprayed by the nozzle 61 onto the surface of the oil cooler housing 4 can flow into the annular waste liquid tank 11 for collection and be discharged through the drain pipe 12.

[0031] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
