DETAILED DESCRIPTION

[0022] In order to help those skilled in the art better understand the technical solutions of the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0023] Reference Figures 1 to 3 The present embodiment provides a cold insertion and air tightness testing device for an oil filter, which integrates cold insertion and air tightness testing. It is capable of cold inserting the oil filter 6 to install the bushing, and can also perform air tightness testing on the oil filter 6 after the bushing is installed. The top of the oil filter 6 of this embodiment has a first through hole 61, and the top surface of the first through hole 61 is inclined. One end of the oil filter 6 has a second through hole 62, and the first through hole 61 is connected to the second through hole 62. The oil filter 6 has a sealed state and an open state. When the first through hole 61 and the second through hole 62 are both sealed, the oil filter 6 is in a sealed state; when the first through hole 61 and the second through hole 62 are both unsealed, the oil filter 6 is in an open state.

[0024] The cold plug and air tightness detection device includes a support frame 1, a cold plug mechanism 2 arranged on the top of the support frame 1, a positioning platform 3, a first sealing mechanism 4 and a second sealing mechanism 5 arranged at the bottom of the support frame 1. The positioning platform 3 is provided with a positioning groove 31 matching the outer contour of the oil filter 6 for placing the oil filter 6; the first sealing mechanism 4 is used to seal the first through hole 61, and the second sealing mechanism 5 is used to seal the second through hole 62 so that the oil filter 6 is in a sealed state.

[0025] Furthermore, the support frame 1 includes, from top to bottom, a first fixed plate 11, a second fixed plate 12 and a third fixed plate 13 which are parallel to each other. A plurality of guide columns 14 are arranged between the first fixed plate 11 and the second fixed plate 12, and a plurality of support columns 15 are arranged between the second fixed plate 12 and the third fixed plate 13; the guide columns 14 and the support columns 15 are both perpendicular to the first fixed plate 11, and the distance between the first fixed plate 11 and the second fixed plate 12 is greater than the distance between the second fixed plate 12 and the third fixed plate 13.

[0026] Furthermore, the first sealing mechanism 4 includes a first driver 41, a connecting assembly, a bracket 46, a base 47, a connecting rod 44 and a pressure block 45. The base 47 is located on one side of the positioning platform 3. One end of the bracket 46 is fixedly connected to the top surface of the second fixed plate 12, and the other end of the bracket 46 is fixedly connected to the shell of the first driver 41; the bottom surface of the base 47 is also fixedly connected to the top surface of the second fixed plate 12, and a pin 48 is provided between the top of the base 47 and one end of the connecting rod 44. The pin 48 is fixedly connected to the top of the base 47, and one end of the connecting rod 44 can rotate around the pin 48. The pressure block 45 is fixedly arranged at the other end of the connecting rod 44. In this embodiment, the pressure block 45 is set to be cylindrical. The area of ​​the bottom surface of the pressure block 45 is larger than the area of ​​the top surface of the first through hole 61, ensuring that the pressure block 45 can seal the first through hole 61. Specifically, when the oil filter 6 is in a sealed state, the pressure block 45 covers the first through hole 61 and the bottom surface of the pressure block 45 is parallel to the top surface of the first through hole 61.

[0027] The first actuator 41 is tilted, with its telescopic shaft facing the positioning platform 3. The connecting assembly is fixedly connected to one end of the telescopic shaft of the first actuator 41. The connecting assembly includes a clamping block 42 and a connecting shaft 43 fixedly mounted at one end of the telescopic shaft of the first actuator 41. A groove 421 is defined in the center of the clamping block 42, into which a connecting rod 44 can extend, so that the two sides of the clamping block 42 are located on either side of the connecting rod 44. Specifically, the connecting rod 44 is arc-shaped and has an arc-shaped slot 441 extending through its thickness for the connecting shaft 43 to pass through. The two ends of the connecting shaft 43 are then fixedly connected to the two sides of the clamping block 42. When driven by the first actuator 41, the telescopic shaft extends. The sliding of the connecting shaft 43 in the slot 441 drives the connecting rod 44 to rotate about the latch 48, causing the pressure block 45 to move closer to or further away from the top surface of the first through-hole 61.

[0028] Furthermore, the second sealing mechanism 5 includes a second actuator 51, a plug 52 fixedly connected to one end of the telescopic shaft of the second actuator 51, a fifth fixing plate 53 fixedly disposed on one end of the top surface of the second fixing plate 12, and two bent plates 54 fixedly disposed at both ends of the fifth fixing plate 53. The two ends of the housing of the second actuator 51 are respectively fixedly connected to the top of one of the bent plates 54, thereby securing the second actuator 51 to the fifth fixing plate 53. The second actuator 51 is configured to drive the plug 52 toward or away from the second through hole 62. The plug 52 is configured to accommodate one end of the oil filter 6 having the second through hole 62, thereby sealing the second through hole 62. When one end of the oil filter 6 is located within the plug 52, the outer wall of the oil filter 6 is aligned with the inner wall of the plug 52 to ensure an effective seal. Furthermore, an air inlet 521 is defined on the side wall of the plug 52, communicating with the interior of the plug 52 to facilitate air flow through the air inlet 521 for airtightness testing.

[0029] Furthermore, the cold insertion mechanism 2 includes a third actuator 21 connected to the first fixing plate 11, a fourth fixing plate 22 fixedly connected to one end of the telescopic shaft of the third actuator 21, and two cold insertion rods 23 fixedly connected to the fourth fixing plate 22. The cold insertion rods 23 are positioned toward the positioning platform 3, and the housing of the third actuator 21 is fixedly connected to the first fixing plate 11. The fourth fixing plate 22 is positioned between the first fixing plate 11 and the second fixing plate 12. The third actuator 21 is used to drive the fourth fixing plate 22 to move up and down along the guide post 14, thereby driving the cold insertion rods 23 to move closer to or further away from the oil filter 6. When the bushing needs to be installed, the third actuator 21 drives the fourth fixing plate 22 and the cold insertion rods 23 downward to install the bushing in the corresponding mounting hole on the oil filter 6.

[0030] The following briefly describes the working process of the cold plug and air tightness detection device in this embodiment:

[0031] First, driven by the third actuator 21, the cold insert rod 23 moves downward to install the bushing into the corresponding mounting hole on the oil filter 6. Subsequently, the telescopic shaft of the first actuator 41 extends, driving the connecting rod 44 to rotate around the latch 48, causing the pressure block 45 to gradually approach the top surface of the first through hole 61 until the two are in contact, sealing the first through hole 61. Then, the telescopic shaft of the second actuator 51 extends, driving the plug 52 toward the positioning platform 3 until the end of the oil filter 6 extends into the plug 52, sealing the second through hole 62. Finally, air is ventilated into the air inlet 521 of the plug 52 to test the oil filter 6 for airtightness.

Their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention.
