DETAILED DESCRIPTION OF THE EMBODIMENTS
[0015] Please refer to Figures 1 - 3 , the present utility model provides the following technical solutions: It includes a bearing frame 1, a conveyor belt 11, and an irradiation lamp 23. The conveyor belt 11 is installed inside the bearing frame 1. The top of the bearing frame 1 is fixedly connected with a detection bin 2. The inside of the detection bin 2 is slidably connected with an outer blocking plate 21. The inner wall of the outer blocking plate 21 is fixedly connected with a light - showing plate 22. The irradiation lamp 23 is installed inside the detection bin 2. The outer blocking plate 21 is located between the light - showing plate 22 and the irradiation lamp 23. An inner tight - fitting ring 3 is arranged inside the bearing frame 1. One side of the inner tight - fitting ring 3 is detachably connected with a linking rod 31. The linking rod 31 slides on the inner wall of the top of the detection bin 2. The inner wall of the top of the detection bin 2 is fixedly connected with a fixed seat 32. One side of the detection bin 2 is fixedly connected with an observation bin 4. Light - shielding covers 41 are installed on one side of the detection bin 2 and one side of the observation bin 4.
[0016] In this implementation: The bearing frame 1 is used to support and connect various components, so as to complete the detection work of the inner and outer diameter damages of the sealing ring through the cooperation of other components. The conveyor belt 11 installed inside the bearing frame 1 is used to convey the sealing ring, so that the sealing ring can be conveyed to a suitable position for detection operations, and the sealing ring after the detection can be directly placed on the top of the conveyor belt 11 and conveyed to other operation areas. The detection chamber 2 fixed to the top of the bearing frame 1 is used to support components such as the outer blocking plate 21, so that the outer blocking plate 21 can continuously be located at a suitable position inside the detection chamber 2. When it is necessary to detect the sealing ring, the staff can slide the outer blocking plate 21 with a hole diameter adapted to the outer diameter of the sealing ring into the detection chamber 2. Then, the staff can choose to install the inner close-fitting ring 3 corresponding to the inner diameter size of the sealing ring on one side of the linkage rod 31. At this time, the inner close-fitting ring 3 will be located inside the outer blocking plate 21. Then, the staff can slide the sealing ring conveyed by the conveyor belt 11 to the outside of the inner close-fitting ring 3. Since the inner and outer diameters of the sealing ring respectively correspond to the diameter of the inner close-fitting ring 3 and the diameter of the hole inside the outer blocking plate 21, the sealing ring will be in close contact with the inner close-fitting ring 3 and the outer blocking plate 21. Then, the staff can activate the irradiation lamp 23, and the irradiation lamp 23 will irradiate light in the direction of the inner close-fitting ring 3. When the light reaches the positions of the outer blocking plate 21, the sealing ring and the inner close-fitting ring 3, it will be blocked. However, if there are damages to the inner and outer diameters of the sealing ring, resulting in some positions unable to be in close contact with the outer blocking plate 21 and the inner close-fitting ring 3, the light will pass through the gap and irradiate on the surface of the light-emitting plate 22. A light-shielding cover 41 is installed on one side of the detection chamber 2, and the light-shielding cover 41 will block the light source on one side of the detection chamber 2, so that the external light source will not enter the position where the light-emitting plate 22 is located. At this time, the staff can be located inside the observation chamber 4 and observe the area where the light-emitting plate 22 is located. When it is found that there is light passing through the gap between the sealing ring and the outer blocking plate 21 and the inner close-fitting ring 3 and irradiating on the surface of the light-emitting plate 22, that is, there is a scratched position on this sealing ring, the staff can take out the sealing ring and place it separately. When no light is found to pass through, there are no scratches on the inner and outer diameters of the sealing ring. At this time, the staff can push the sealing ring and the inner close-fitting ring 3 backward. When the inner close-fitting ring 3 moves, it will drive the linkage rod 31 to move synchronously. At this time, the spring installed between the linkage rod 31 and the fixed seat 32 will be compressed and store energy. When the inner close-fitting ring 3 and the sealing ring move a certain amount, the staff can take out the sealing ring from the outside of the inner close-fitting ring 3 and directly place it above the conveyor belt 11, so that the qualified sealing rings can move out from one side of the detection chamber 2 through the conveyance of the conveyor belt 11. Since the light-shielding cover 41 is a flexible structure, when the sealing ring touches the light-shielding cover 41, it can drive the light-shielding cover 41 to move. When the sealing ring moves out from the inside of the detection chamber 2, the light-shielding cover 41 will move to the initial position by its own gravity and continue to block one side of the detection chamber 2.The spring installed between the linkage rod 31 and the fixed seat 32 will drive the linkage rod 31 and the inner tight-fitting ring 3 to move through the elastic release force, so that the inner tight-fitting ring 3 moves to the inner side of the outer blocking plate 21, waiting for the staff to continue the detection operation of the sealing ring.
[0017] A support chassis 12 is fixedly connected to the bottom end of the bearing frame 1, and a restraint rod 13 is fixedly connected to the inner side of the bearing frame 1; the support chassis 12 fixed to the bottom end of the bearing frame 1 is used to support the bearing frame 1, so that the bearing frame 1 can complete the support work for other components, and then through the cooperation of other components, complete the detection operation of the inner and outer diameters of the sealing ring. The restraint rod 13 is used to block the sealing ring that has not been detected. The unsealed sealing ring will be limited to one side by the restraint rod 13, so that the staff can take the sealing ring for detection operation. And the restraint rod 13 can block the bottom of the outer blocking plate 21 to prevent a large amount of external light from entering the corresponding position of the light display board 22 through the bottom of the outer blocking plate 21, which will affect the staff's judgment on whether there is light passing through the gap between the sealing ring and the outer blocking plate 21 and the inner tight-fitting ring 3 and irradiating on the surface of the light display board 22.
[0018] A limit block 24 is fixedly connected to the inner side of the detection chamber 2, and the position of the limit block 24 corresponds to that of the outer blocking plate 21; the limit block 24 fixed to the inner side of the detection chamber 2 is used to limit the outer blocking plate 21. The position of the limit block 24 corresponds to that of the outer blocking plate 21, so that when the staff slides the outer blocking plate 21 into the detection chamber 2, it will reach the top of the limit block 24, enabling the limit block 24 to complete the limiting and restraining work on the outer blocking plate 21, and then enabling the outer blocking plate 21 to continuously be in a suitable position to complete the auxiliary work during the detection of the sealing ring.
[0019] A guiding groove 25 is opened on the inner wall of the top end of the detection chamber 2, and the linkage rod 31 is slidably connected to the detection chamber 2 through the guiding groove 25; the guiding groove 25 opened on the inner wall of the top end of the detection chamber 2 is used to guide and restrain the sliding of the linkage rod 31. Thus, after the staff completes the detection operation of the sealing ring, by pushing the inner tight-fitting ring 3, the inner tight-fitting ring 3 can drive the linkage rod 31 to move. The linkage rod 31 will guide the movement of the inner tight-fitting ring 3 to prevent the inner tight-fitting ring 3 from tilting, enabling the staff to stably slide the sealing ring and the inner tight-fitting ring 3, and enabling the staff to take out the sealing ring from the outer side of the inner tight-fitting ring 3.
[0020] An operation opening 26 and an inspection hole 27 are provided on one side of the detection bin 2. The inspection hole 27 is located inside the observation bin 4. The operation opening 26 provided on one side of the detection bin 2 allows space for the operation of the staff, so that the staff can insert the arm into the inside of the detection bin 2 through the operation opening 26, complete placing the sealing ring between the outer blocking plate 21 and the inner fitting ring 3, and then complete the detection work on the damage of the inner and outer diameters of the sealing ring. The inspection hole 27 provided on one side of the detection bin 2 allows space for personnel to observe the corresponding position of the light-emitting plate 22 inside the detection bin 2, so that the staff can know whether the light irradiates the surface of the light-emitting plate 22 through the gap between the sealing ring and the outer blocking plate 21 and the inner fitting ring 3, and then judge whether there is damage to the inner and outer diameters of the sealing ring.
[0021] The working principle and usage process of the present utility model: When the staff needs to detect the sealing ring, the staff can slide the outer blocking plate 21 with an aperture adapted to the outer diameter of the sealing ring into the inside of the detection bin 2. Then the staff can select to install the inner fitting ring 3 corresponding to the inner diameter size of the sealing ring on one side of the linkage rod 31. At this time, the inner fitting ring 3 will be located inside the outer blocking plate 21. Then the staff can place the sealing ring on the top of the conveyor belt 11, and the conveyor belt 11 will convey the sealing ring. When the conveyor belt 11 drives the sealing ring to move and contact the restraint rod 13, the restraint rod 13 will limit the position of the sealing ring, so that the staff can slide the sealing ring to the outside of the inner fitting ring 3. Since the inner and outer diameters of the sealing ring respectively correspond to the diameter of the inner fitting ring 3 and the diameter of the hole inside the outer blocking plate 21, the sealing ring will be in close contact with the inner fitting ring 3 and the outer blocking plate 21. Then the staff can start the irradiation lamp 23, and the irradiation lamp 23 will irradiate light in the direction of the inner fitting ring 3. When the light reaches the positions of the outer blocking plate 21, the sealing ring and the inner fitting ring 3, it will be blocked. If there is damage to the inner and outer diameters of the sealing ring, resulting in some positions not being in close contact with the outer blocking plate 21 and the inner fitting ring 3, the light will pass through the gap and irradiate on the surface of the light-emitting plate 22, that is, there is a scratched position on this sealing ring. The staff can take out the sealing ring and place it separately. When no light is found to pass through, there is no scratch on the inner and outer diameters of the sealing ring. At this time, the staff can push the sealing ring and the inner fitting ring 3 backward. When the inner fitting ring 3 moves, it will drive the linkage rod 31 to move synchronously. At this time, the spring installed between the linkage rod 31 and the fixed seat 32 will be compressed and store energy. When the inner fitting ring 3 and the sealing ring move a certain amount, the staff can take out the sealing ring from the outside of the inner fitting ring 3 and directly place it above the conveyor belt 11, so that the qualified sealing ring can move out from one side of the detection bin 2 through the conveyance of the conveyor belt 11, and the sealing ring can be conveyed to the subsequent operation area through the conveyor belt 11.
