Description

Technical Field

[0001] The utility model relates to the technical field of reducer housing detection, in particular to a leakage-proof reducer housing air tightness detection tool. Background Art

[0002] During the operation of the reducer, if the housing is not airtight enough, energy will be lost through the leakage path, reducing the working efficiency of the equipment. Leakage may also cause the oil temperature inside the reducer to rise, affecting the normal operation and life of the equipment. Oil leakage not only pollutes the environment, but may also have an adverse effect on the normal operation of the equipment. Poor airtightness may cause equipment failure during operation and even cause safety accidents. Through airtightness testing, potential safety hazards can be discovered and repaired in a timely manner.

[0003] A Chinese patent with publication number CN218411606U discloses a shell air tightness detection tool, comprising a lower mold assembly, on which a shell to be detected is placed, and the shell is provided with an upper cover, a lower cover and a side concave cover, the upper part of the lower mold assembly is in contact with the lower cover, and the lower mold assembly is provided with an air inlet channel, and the rear end of the air inlet channel is placed in the shell; an upper mold assembly, the upper mold assembly is movably arranged on the lower mold assembly and located above the shell, the upper mold assembly is movably in contact with the upper cover; a sealing mechanism, which is arranged on the lower mold assembly and located inside the shell, a sealing block is movably arranged on the sealing mechanism, the side concave cover is recessed inwardly relative to the side of the shell to form an inner convex plane, and the sealing block can be movably pressed against the inner convex plane.

[0004] The above-mentioned prior art solutions have the following defects: the current technical solutions mainly judge the air tightness of the shell by inflating the shell through the air inlet channel and observing whether there is gas leakage. Although this method is effective in most cases, it relies on accurate measuring instruments to indirectly judge the leakage. In some cases, if the leakage is very small or difficult to accurately detect through pressure changes, this method may not be intuitive and sensitive enough.

[0005] To this end, we proposed a leak-proof reducer housing air tightness detection tool to solve the above problems. Utility Model Content

[0028] The detection mechanism includes a fixing unit and a bubble detection unit;

[0029] The fixing unit includes a detection plate 7, a water leakage hole 701, a cylinder 702, a fixing block 703, an electric push rod 704 and a clamping ring 705. The water leakage hole 701 is provided on the detection plate 7. The detection plate 7 is used to place the reducer housing for air tightness detection. There are multiple water leakage holes 701, which are equidistantly provided on the detection plate 7. The bottom of the cylinder 702 is fixedly connected to the upper surface of the detection plate 7, the bottom of the fixing block 703 is fixedly connected to the output end of the cylinder 702, the electric push rod 704 is fixedly connected to the fixing block 703, and the clamping ring 705 is connected to the output end of the electric push rod 704. The clamping ring 705 is driven by the fixing block 703 and the electric push rod 704 to achieve stable clamping of the reducer housing, ensuring that the position is fixed during the detection process;

[0030] The bubble detection unit includes a guide rod 6, a second motor 901, a connecting seat 902 and a threaded rod 903. The two guide rods 6 are respectively fixedly connected to the inside of the water tank 2 and under the top plate 5. Both ends of the detection plate 7 are movably connected to the guide rods 6. The front of the connecting seat 902 is fixedly connected to the middle of the back of the top plate 5. Both ends of the threaded rod 903 are respectively connected to the connecting seat 902 and the inside of the water tank 2. The detection plate 7 is threadedly connected to the threaded rod 903 at the rear. The output end of the second motor 901 is connected to the top of the threaded rod 903 through a coupling. The threaded rod 903 is driven to rotate by the second motor 901, thereby driving the detection plate 7 to move up and down, thereby realizing the lifting function during the detection process. Example

[0031] On the basis of the first embodiment, a drying structure is provided on both sides of the bracket 3, and the drying structure includes a bellows 4, a fan 401, an air outlet pipe 402, a moisture absorption plate 403, a heating strip 404 and a through hole 405. The bellows 4 is fixedly connected to the outside of the bracket 3, and the fan 401 is arranged on the outside of the bellows 4 to generate a directional airflow and send air into the bellows 4. The moisture absorption plate 403 is fixedly connected to the inside of the bellows 4, and activated carbon is arranged inside the moisture absorption plate 403. The heating strip 404 is fixedly connected to the right side of the moisture absorption plate 403, and there are multiple heating strips 404, which are fixedly connected to the front and rear sides of the inner wall of the bellows 4 at equal distances. The through hole 405 is opened on the right side of the bellows 4, and the air outlet pipe 402 is fixedly connected to the through hole 405. The air outlet pipe 402 guides the dry air in the bellows 4 to the surface of the reducer housing to achieve rapid air drying.

[0032] A motor 801 is fixedly connected to the middle of the upper surface of the top plate 5, and the output end of the motor 801 is connected to a connection disk 802 through a coupling, and a sponge block 803 is connected to the lower surface of the connection disk 802. The motor 801 drives the connection disk 802 to rotate, thereby driving the sponge block 803 to rotate, and preliminarily wipes the surface of the reducer housing to remove most of the moisture on the surface.

[0033] Working principle: Place the reducer housing on the detection plate 7, push the fixed block 703 through the cylinder 702, and then use the electric push rod 704 to drive the clamping ring 705 to stably clamp the housing. In this way, the housing is fixed in position and will not move during the detection process. Start the motor 2 901 to drive the threaded rod 903 to rotate. Since the detection plate 7 is connected to the threaded rod 903 by threads, the detection plate 7 will move up and down with the rotation of the threaded rod 903. When the detection plate 7 descends, the reducer housing will be immersed in the water of the water tank 2. If there is leakage in the housing, bubbles will be generated. By observing the generation of bubbles, the air tightness of the housing can be judged.

[0034] After the detection, the motor 801 is started to drive the connection disk 802 to rotate, thereby driving the sponge block 803 to rotate. The sponge block 803 contacts the surface of the shell to remove most of the moisture on the surface. At the same time, the air-drying structure is started, and the fan 401 generates a directional airflow to send air into the bellows 4. The air is dehumidified by the moisture absorption plate 403, and then heated by the heating strip 404 to form dry hot air. The dry hot air is guided to the surface of the reducer shell through the air outlet pipe 402 to achieve rapid air drying.
