Description

Technical Field

[0001] The utility model relates to a transmission housing water test machine filtering device, belonging to the technical field of transmission inspection devices. Background Art

[0002] The transmission needs to pass 100% water test to ensure that its sealing performance meets the design requirements. The existing water test operation has the following problems:

[0003] 1. The water test machine requires the operator to visually check the leakage points of the workpiece in the water. However, some impurities generated during the water test will float on the water surface and some will float in the water, making it difficult for the operator to clearly observe the leakage of the workpiece, thereby increasing the risk of misjudgment and missed inspection, which may cause serious quality problems to flow out.

[0004] 2. When the workpiece is immersed in polluted water for a long time, impurities are easily adhered to its surface. These impurities not only affect the appearance quality of the workpiece, but are also likely to have an adverse effect on its performance, resulting in poor cleanliness. In order to ensure the cleanliness of the product, manufacturers have to invest a lot of manpower and material resources for secondary cleaning, which increases production costs.

[0005] 3. Due to serious water pollution, the water in the water test machine tank needs to be replaced 7 times a month. About 3 tons of sewage needs to be discharged every 3 days of production. It takes 3 hours to drain and flush the water tank. It takes 21 hours 7 times a month. This not only wastes production time and water resources, but also pollutes the environment. Utility Model Content

[0006] In order to solve the problems existing in the background technology, the utility model provides a transmission housing water test machine filtering device.

[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a transmission housing water test machine filtering device, comprising a filtering mechanism, a floating object collection bucket, a water pump 1 and a water pump 2; the floating object collection bucket is arranged in the water test machine, the water outlet end of the floating object collection bucket is connected to the water inlet end of the water pump 2, the water inlet end of the water pump 1 is connected to the bottom of the water test machine, the water outlet end of the water pump 2 and the water outlet end of the water pump 1 are both connected to the water inlet end of the filtering mechanism, the filtering mechanism is fixed on the water test machine, and the water outlet end of the filtering mechanism is connected to the water test machine.

[0008] The side wall of the floating object collecting bucket is provided with a plurality of water inlet holes.

[0009] The filtering mechanism includes an outer shell, an upper filter cotton, a coarse sand layer, activated carbon, a fine sand layer, a lower filter cotton and a mesh frame; the water inlet end of the upper end of the outer shell is connected to the water outlet end of water pump 2 and the water outlet end of water pump 1, and a mesh frame is placed in the outer shell. The lower filter cotton, the fine sand layer, the activated carbon, the coarse sand layer and the upper filter cotton are stacked and filled in sequence from bottom to top, and the water outlet end of the lower end of the outer shell is connected to the water test machine.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model effectively discharges and filters the impurities in the water tank of the water test machine through the filtering mechanism, which is convenient for the operator to clearly view the workpiece and find defective products in time, avoiding the problem of defective parts flowing out due to the operator's blurred vision, and improving the water test efficiency and quality of the transmission.

[0012] 2. The utility model ensures the cleanliness of the water in the water tank of the water test machine, and then ensures the cleanliness of the product after the water test, avoids the secondary cleaning of the product, improves the water test efficiency of the transmission, and reduces the production cost.

[0013] 3. The utility model only needs to replace the water in the water tank once a month, saving 18 hours of work and reducing the discharge of 18 tons of sewage per month. Since the sewage treatment cost is about 80 yuan per ton, the annual sewage discharge is reduced by 216 tons, so the sewage treatment cost is saved by about 17,000 yuan, reducing the waste of water resources, avoiding environmental pollution, and saving production costs.
