Description

Technical Field

[0001] The invention relates to the technical field of fuel filter air tightness detection, in particular to a feeding device for fuel filter air tightness detection. Background Art

[0002] The function of the fuel filter is to prevent particulate matter, water and impurities in the fuel, and to protect the precision parts of the fuel system from wear and other damage. The fuel filter is provided with an oil inlet pipe and an oil outlet pipe on both sides. Before packaging, the fuel filter needs to be tested for its sealing to determine whether the product is qualified. The existing test for the sealing of the fuel filter usually involves inflating the inside of the filter and judging whether the air tightness of the filter is qualified by observing the pressure gauge during inflation.

[0003] The utility model patent application document with publication number "CN208043353U" discloses a dry-type sealing detection device for a fuel filter, which is mainly composed of an operating table, a mounting frame, a lifting cylinder, a lifting seat, a slider, an air supply detection group, an air source hose, an air supply hose, a tightening cylinder, a rear tightening cylinder, a positioning plate, a connecting rod and a fixed sealing nozzle. This technical solution adopts a dry detection method for detection, and has high detection efficiency and is easy to operate.

[0004] The dry-type sealing detection device for fuel filters disclosed in the above document has the following defects: during use of the sealing detection device, multiple fuel filters to be tested are manually inserted into the corresponding fixed sealing nozzles one by one, and then subsequent testing steps are performed. After the fuel filter testing is completed, workers are required to remove the tested fuel filters from the fixed sealing nozzles, and then put the next batch of fuel filters to be tested back on the fixed sealing nozzles for the next batch of testing. This is inconvenient to use and the testing effect is poor.

[0005] It can be seen from this that the existing sealing detection device does not have a good feeding structure, and it is necessary to improve the existing deficiencies and provide a feeding device for fuel filter air tightness detection. Summary of the invention

A second driving motor 4011 is mounted on the upper surface of the third placement seat 408, and a driving gear 4012 is mounted on the output end of the second driving motor 4011. The driving gear 4012 is meshed and connected with the two sets of second racks 4010. The driving gear 4012 is a half-tooth gear, and the two sets of second racks 4010 are staggered in the through slot. Before use, the second driving motor 4011 is started so that the output end of the second driving motor 4011 drives the driving gear 4012 to rotate. When the driving gear 4012 is meshed with the second rack 4010 on the inner upper surface of the through slot, the driving gear 4012 pushes the second rack 4010 to move to the right along the through slot. At the same time, the first rack 407 moves to the right in the first slide rail 406. During the movement of the first rack 407, the first driven gear 405 is driven to rotate axially counterclockwise along the axis. The second placement seat 404 synchronously rotates axially counterclockwise along the axis. When the driving gear 4012 is no longer meshed with the second rack 4010 on the inner upper surface of the through slot, the second placement seat 404 flips 90° to the left. At the same time, the fuel filter 10 is conveyed through the conveyor. The structure 3 falls onto the second placement seat 404. When the fuel filter 10 falls onto the second placement seat 404, the driving gear 4012 will mesh with the second rack 4010 on the lower surface of the through slot, and the driving gear 4012 will push the second rack 4010 to move to the left along the through slot.

When the driving gear 4012 is no longer meshed with the second rack 4010 on the lower surface of the through slot, the second placement seat 404 flips rightward 90°, and the fuel filter 10 falls into the first first placement seat 505. By starting the first driving motor 507, the output end of the first driving motor 507 drives the driving wheel 508 to rotate, and the driving wheel 508 drives the first driven wheel 506 to rotate through the belt 509, so that the first driven wheel 506 drives the placement plate 504 and the first placement seat 505 to rotate counterclockwise through the rotating shaft 503. When the placement plate 504 rotates 90 degrees, the second first placement seat 505 on the placement plate 504 is located on the same straight line as the second placement seat 404. At this time, another fuel filter 10 falls to the second first placement seat 505 through the flip assembly 4. On the first placement seat 505, when the placement plate 504 rotates 180°, the first first placement seat 505 on the placement plate 504 is located at the airtight detection structure 8, and the fuel filter 10 on the first first placement seat 505 can be detected by starting the airtight detection structure 8. When the placement plate 504 rotates 270°, the first first placement seat 505 on the placement plate 504 is located at the blanking structure 9, and the blanking structure 9 is started to make the fuel filter 10 that has been tested detach from the first placement seat 505, and the airtightness test is completed; A connecting frame 5010 is also installed on the lower surface of the operating table 1. An electric telescopic rod 5011 is installed in the connecting frame 5010. A connecting piece 5012 is installed at the output end of the electric telescopic rod 5011. A second driven wheel 5013 is rotatably connected in the connecting piece 5012. When the belt 509 is relatively loose, the electric telescopic rod 5011 is started so that the output end of the electric telescopic rod 5011 pushes the connecting piece 5012 to move toward one end close to the belt 509, so that the second driven wheel 5013 contacts the belt 509 and changes the travel of the belt 509, thereby extending the service life of the belt 509; A second connecting plate 4013 is provided on one side of the second side plate 402, a first slide rail 406 is installed on the upper surface of the second connecting plate 4013, an auxiliary supporting plate 4014 is provided on the lower surface of the second side plate 402, and one end of the auxiliary supporting plate 4014 is provided on the outer surface of the second side plate 402; The second connecting plate 4013 can support the first slide rail 406, and the auxiliary supporting plate 4014 can increase the strength of the second connecting plate 4013 and extend the service life of the second connecting plate 4013; The limiting assembly 6 includes a second slide rail 601, which is mounted on the outer surface of the second side plate 402, and the upper surface of the second slide rail 601 is slidably connected to the third rack 602, the outer surface of the second side plate 402 is provided with a mounting groove 40201, and the inner surface of the mounting groove 40201 is rotatably connected to the second connecting rod 603, the outer surface of the second connecting rod 603 is provided with a cam 604 and a second driven gear 605, and one end of the second connecting rod 603 is provided with a knob 606, and the outer surface of the second side plate 402 is provided with a sealing plate 607, and the outer surface of the sealing plate 607 is provided with a through hole, and the second connecting rod 603 is rotatably connected to the inner surface of the through hole.

A push rod 7 is slidably connected in the through opening. One end of the push rod 7 is clamped in the slot, and the other end of the push rod 7 extends to the inside of the second slide rail 601. When the first rack 407 moves, the push rod 7 will move synchronously in the through hole. When the first rack 407 moves for the first time, the first rack 407 pushes the push rod 7 to move the push rod 7. When the push rod 7 contacts the third rack 602, the push rod 7 will push the third rack 602 to move, so that the third rack 602 moves to the right in the second slide rail 601. During the movement of the third rack 602, the second driven gear 605 and the second connecting rod 603 are driven to rotate counterclockwise along the axis with the through hole as the center. At the same time, the cam 604 in the mounting groove 40201 rotates with the second connecting rod 603. The connecting rod 603 rotates synchronously counterclockwise along the axis with the connecting rod 603 as the center. During the rotation of the cam 604, the protruding end of the cam 604 gradually contacts the baffle 608 and pushes the baffle 608 and the limiting rod 6010 to move outward. At the same time, the spring 609 gradually contracts. When the protruding end of the cam 604 completely contacts the baffle 608, the limiting rod 6010 is completely installed inside the mounting hole, thereby completing the fixed installation of the first slide rail 406 and the second side plate 402, preventing the first slide rail 406 from detaching from the second side plate 402 during use, and achieving a better fixing effect. When the first slide rail 406 needs to be removed, the first rack 407 is first reset, and then the knob 606 is turned clockwise so that the protruding end of the cam 604 gradually cancels contact with the baffle 608, the spring 609 gradually restores its elasticity and pushes the baffle 608 to move inwardly of the mounting groove 40201, and at the same time, the limiting rod 6010 gradually disengages from the mounting hole. When the protruding end of the cam 604 completely cancels contact with the baffle 608, the limiting rod 6010 completely disengages from the mounting hole, and the first slide rail 406 and the second side plate 402 are no longer fixedly installed, thereby facilitating disassembly.
