Description

Technical Field

[0001] The present invention relates to the field of filter production, and in particular to a filter sealing detection device. Background Art

[0002] An oil filter, also known as an oil filter element, is used to remove impurities such as dust, metal particles, carbon deposits, and soot particles in the oil to protect the engine. When producing a filter, it is necessary to ensure that the filter body is in a sealed state and there is no air leakage. Patent Application No.: CN201721104397.4 discloses a filter airtightness detection device, including: a water tank, a water level sensor, a support frame, a controller, an air cylinder, a sealing cover, a water inlet cylinder, a support plate, a fixing cylinder, a top frame. It is characterized in that: a water level sensor is pasted on the inner wall of the water tank, a support frame is fixed on the upper plane of the water tank by bolts, a controller and an air cylinder are installed on the upper plane of the support frame by bolts, the air cylinder is connected to a sealing cover through a trachea. During detection, the sealing cover is connected to the oil outlet of the filter, then the filter is placed in the support plate, and the filter is immersed in water, causing the water level to rise. When the water level reaches the water level sensor, the air cylinder pumps air into the filter, and at the same time the water inlet cylinder stops, and then the worker observes whether there are bubbles. However, such a detection device can only detect one filter at a time, resulting in low detection efficiency.

[0003] The present invention is research and proposed in view of the deficiencies of the prior art. Summary of the Invention

[0004] The object of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a filter sealing detection device.

[0005] The present invention can be realized by the following technical solutions:

[0006] The present invention discloses a filter seal detection device, which includes a bottom plate. A water tank is fixed on the bottom plate. Above the bottom plate, there is a sliding plate, which is driven to move by a test motor. Multiple test cylinders are fixed on the sliding plate. Below the sliding plate, there is a fixing plate. The ends of the piston rods of the test cylinders are all fixed to the fixing plate. On both sides below the fixing plate, fixing blocks are symmetrically fixed. On each fixing block, there is a rotating shaft rotatably connected to the fixing block. The rotating shaft is driven to rotate by a corresponding rotating motor. A support plate is fixed between the two rotating shafts. Support grooves are evenly arranged on the support plate. On one side of the support plate, there is a positioning plate. Positioning grooves are arranged at positions corresponding to the support grooves on the positioning plate. Multiple electromagnets are evenly fixed on the support plate. Metal blocks are fixed at positions corresponding to the electromagnets on the positioning plate. Limit plates are fixed at both ends of the support plate. Connecting blocks are fixed at both ends of the positioning plate. Limit rods are fixed on the limit plates. The limit rods pass through the connecting blocks and are slidably connected to the connecting blocks. Springs are also fixed between the limit plates and the connecting blocks. An installation plate is also arranged in the water tank. Drain pipes are fixed at positions corresponding to the support grooves on the installation plate. A connecting plate is fixed above the installation plate. Multiple lifting cylinders are fixed on the water tank. The ends of the piston rods of the lifting cylinders are all fixed to the connecting plate. Place each filter to be tested between the support groove and the positioning groove. The electromagnets are energized. After being energized, the electromagnets generate magnetism to attract the metal blocks at the corresponding positions. The positioning plate moves closer to the support plate. After the filter is fixed between the support plate and the positioning plate, the test motor drives the screw rod to rotate, and the sliding plate moves above the water tank. The test cylinders are started. The piston rods on the test cylinders extend, and the fixing plate descends. The filter enters the water in the water tank. When the filter is filled with water, the rotating motor drives the rotating shaft to rotate. After the filter rotates 180 degrees, its opening faces downward. The lifting cylinders are started. The piston rods on the lifting cylinders extend, and the drain pipes extend into the filter. A certain amount of gas is discharged into each filter through an air pump, and the water in the filter is discharged. After a period of time, confirm whether there are cracks in the filter by checking the liquid level height in the water tank. When the filter is cracked, the water outside the filter enters the filter through the crack, resulting in a decrease in the liquid level height in the water tank. This device can perform seal tests on multiple filters at one time, greatly improving the test efficiency of the filters.

[0007] Preferably, a vertical plate is fixed on one side of the bottom plate. A screw rod and a sliding rod are arranged on the vertical plate. The screw rod passes through the sliding plate and is threadedly connected to the sliding plate. The sliding rod passes through the sliding plate and is slidably connected to the sliding plate. The screw rod is fixed to the output end of the test motor.

[0008] Preferably, a scale is also arranged on the water tank.

[0009] Preferably, limit blocks are fixed at the ends of the limit rods.

[0010] Preferably, a lead screw is fixed to the output end of the rotary motor. A threaded pipe threadedly connected to the lead screw is arranged on the lead screw.
