Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Specific examples are given below.

[0025] like Figures 1 to 4As shown, an oil filter production and testing equipment described in an embodiment of the utility model comprises a testing box 1; a pair of hydraulic rods 11 are fixedly connected to the side wall of the testing box 1; a first fixing plate 12 is fixedly connected to the end of the hydraulic rod 11; a plurality of electric push rods 13 are fixedly connected to the top of the first fixing plate 12; a pressure ring 14 is fixedly connected to the end of the electric push rod 13; an air intake pipe 15 is connected to the side wall of the pressure ring 14; a second fixing plate 16 is connected to the bottom of the first fixing plate 12; a plurality of groups of limiting plates 17 are fixedly connected to the top of the second fixing plate 16; when working, water is first added to the testing box 1, and then the oil filter is placed in the gap between the limiting plates 17, and then the electric push rod 13 is started to drive the pressure ring 14 to approach the filter port, and when the pressure ring 14 contacts the filter port, it can cover it, and at this time, the external air source is connected to the air intake pipe 15 to inflate the filter, and then the hydraulic rod 11 is started to drive The first fixing plate 12 and the second fixing plate 16 are moved into the detection box 1. At this time, the filter placed on the top of the second fixing plate 16 can be moved into the water in the detection box 1. If the filter leaks, bubbles will appear in the water. The sealing of the filter can be judged by whether bubbles are generated. After the detection, the hydraulic rod 11 is started again to drive the second fixing plate 16 to move upward to remove the filter from the water, and then the electric push rod 13 is started again to drive the pressure ring 14 away from the filter, and then the filter is removed, and then the cycle is repeated to detect the next batch. Through the above structure, the hydraulic rod 11 is set to drive the first fixing plate 12 and the second fixing plate 16 to move up and down, which can drive the filter placed on the second fixing plate 16 to enter and leave the water in the detection box 1, so as to facilitate the filter to be separated from the water after the detection is completed, so as to improve the convenience of retrieving the filter after the detection is completed.

[0026] like Figures 1 to 4 As shown, a plurality of baffles 2 are fixedly connected to the top of the second fixed plate 16; a plurality of spring rods 21 are slidably connected to the middle of the baffle 2; a top block 22 is fixedly connected to the end of the spring rod 21; during operation, when the oil filter is placed between the limit plates 17, the spring rod 21 is pulled to move outward, and then the filter is placed between the limit plates 17, and then the spring rod 21 is released to make the top block 22 contact with the filter surface. At this time, the rebound force generated by the spring rod 21 acts on the filter surface through the top block 22, and the filter can be clamped and fixed from the filter surface. Through the above structure, a baffle 2 is set to connect the spring rod 21 and the top block 22, and the filter can be clamped and fixed from the surface when it is placed, so as to improve the stability of the filter position during detection and reduce the situation where the position slides and causes the connection to be loose and leak.

[0027] like Figure 2 and Figure 3As shown, the side wall of the detection box 1 is fixedly connected to a third fixing plate 3; the top of the third fixing plate 3 is fixedly connected to a plurality of bellows 31; the side wall of the bellows 31 is provided with a plurality of air holes 33; the inner wall of the bellows 31 is fixedly connected to a fan 32; during operation, after the hydraulic rod 11 pulls up the filter after the detection is completed, the fan 32 is started to drive the airflow to blow out from the air holes 33 close to the side of the filter, and when the airflow passes through the surface of the filter, it can be dried to dry the residual moisture on the surface. Through the above structure, the third fixing plate 3 is arranged to connect the bellows 31 and use the fan 32, so that the filter can be blown and dried after the detection is completed to reduce the moisture remaining on the surface of the filter, which may cause corrosion and easy adhesion of dust.

[0028] like Figure 3 As shown, a pair of slide rails 4 are fixedly connected to the side walls of the bellows 31; a filter screen 41 is placed in the slide rails 4; the slide rails 4 and the filter screen 41 are slidably matched; during operation, when the fan 32 drives the airflow into the bellows 31, the airflow will be filtered through the filter screen 41 to filter out dust and other impurities in the airflow. When the filter screen 41 needs to be cleaned, the filter screen 41 can be directly pulled out from the slide rails 4, and the filtered dust can be cleaned and then inserted back into the slide rails 4. Through the above structure, the slide rails 4 and the filter screen 41 are set, and the airflow entering the bellows 31 can be filtered, reducing the situation where dust and impurities in the airflow enter the bellows 31 and cause blockage, and at the same time can reduce the situation where dust is blown onto the filter surface and causes dirt. The sliding cooperation between the slide rails 4 and the filter screen 41 can facilitate the cleaning of the filter screen 41, thereby improving the convenience during use.

[0029] like Figure 3 As shown, an air guide cover 5 is fixedly connected to the top of the third fixed plate 3; the air guide cover 5 is arranged on the side away from the filter 41; during operation, when the air flow appears in the filter, it will pass through the air guide cover 5, and the opening of the air guide cover 5 is reduced toward the filter side. When the air flow enters the air guide cover 5 from the large opening, it is blown onto the filter from the small opening. At this time, the wind force of the air flow will be enhanced. Through the above structure, the air guide cover 5 is arranged to increase the wind force of the air flow blown out by the fan 32, so that the air flow is stronger when it blows onto the filter, so as to improve the drying effect of the moisture on the filter surface.

[0030] like Figure 4 As shown, a plurality of elastic sheets 6 are fixedly connected to the inner wall of the limit plate 17; the elastic sheet 6 is an arc-shaped structure; during operation, when the filter is placed between the limit plates 17, the surface of the filter will contact the plurality of elastic sheets 6, and the arc-shaped ejection of the elastic sheet 6 will be squeezed and deformed by the filter. The rebound force generated at this time acts on the filter, and the filter can be clamped and fixed from the surface. Through the above structure, the elastic sheet 6 is arranged to connect the limit plate 17, and when the filter is placed between the limit plates 17, it can be clamped and fixed from the surface of the filter to improve the stability of the position of the filter when it is placed between the limit plates 17.

[0031] like Figure 4 As shown, the top block 22 is made of rubber. Through the above structure, the top block 22 is set to be made of rubber, which can reduce the wear caused by extrusion when the top block 22 is clamped and fixed on the filter surface, and at the same time increase the friction between the top block 22 and the filter, reducing the rotation of the filter.

[0032] Working principle: first add water into the test box 1, then place the oil filter in the gap between the limit plates 17, then start the electric push rod 13 to drive the pressure ring 14 to approach the filter port, and when the pressure ring 14 contacts the filter port, it can cover it. At this time, connect the external air source to the air intake pipe 15 to inflate the filter, and then start the hydraulic rod 11 to drive the first fixing plate 12 and the second fixing plate 16 to move into the test box 1. At this time, the filter placed on the top of the second fixing plate 16 can be moved into the water in the test box 1. If the filter leaks, Bubbles will appear in the water, and the presence or absence of bubbles can be used to determine whether the filter's sealing is qualified. After the test is completed, the hydraulic rod 11 is started again to drive the second fixed plate 16 to move upward, and the filter is removed from the water. Then the electric push rod 13 is started again to drive the pressure ring 14 away from the filter, and then the filter is removed. Then the cycle is repeated to test the next batch. When the oil filter is placed between the limit plates 17, the spring rod 21 is pulled to move outward, and then the filter is placed between the limit plates 17, and then the spring rod 21 is released to make the top block 22 contact the filter surface. At this time, the rebound force generated by the spring rod 21 acts on the filter surface through the top block 22, and can be clamped and fixed from the filter surface. After the test is completed, the hydraulic rod 11 pulls up the filter, and the fan 32 is started to drive the airflow to blow out from the air hole 33 close to the side of the filter. When the airflow passes through the filter surface, it can be dried to dry the residual moisture on the surface. When the fan 32 drives the airflow into the bellows 31, the airflow will be filtered through the filter screen 41 to filter out impurities such as dust in the airflow. When the filter screen 41 needs to be cleaned, the filter screen 41 can be cleaned. 1 is directly pulled out from the slide rail 4, and after cleaning the filtered dust, it is inserted back into the slide rail 4. When the airflow appears in the filter, it will pass through the air guide cover 5, and the opening of the air guide cover 5 is reduced toward the filter side. When the airflow enters the air guide cover 5 from the large opening, it is blown onto the filter from the small opening. At this time, the airflow will be enhanced. When the filter is placed between the limit plates 17, the surface of the filter will contact with multiple elastic sheets 6. At this time, the arc-shaped ejection of the elastic sheet 6 will be squeezed and deformed by the filter. At this time, the rebound force generated acts on the filter, and it can be clamped and fixed from the surface.
