Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp air tightness detection, in particular to an automobile vehicle lamp air tightness detection machine. Background Art

[0002] With the continuous progress and development of society, the popularity of automobiles is getting higher and higher, so people are paying more and more attention to the practicality and firmness of automobiles. Therefore, in the process of automobile production, it is necessary to conduct airtightness testing on automobile lights to detect whether the lights meet the production standards. The airtightness testing machine has become one of the indispensable equipment in automobile production.

[0003] For example, the Chinese utility model patent with patent publication number CN220239344U includes a main structure; a storage component; a transportation component; wherein the storage component includes four groups of support plates, multiple groups of hooks connected to the bottom outer surface of the support plates, a fixing ring arranged inside any group of hooks, a connecting column connected to the bottom surface of the fixing ring and two groups of storage frames arranged on the lower surface of the connecting column. This patent can solve the problem that the existing air tightness test machine for automobile lights usually directly places the lights in the storage frame after the inspection of the automobile lights is completed, but there is a problem that it is unclear whether the lights placed in the storage frame are qualified or unqualified, which makes the placement of the lights confused, resulting in the elimination of products that pass the inspection of the air tightness test machine, or the use of unqualified products in automobile production, which further causes the problem of damage to the lights when the car is actually used.

[0004] However, in actual use, the storage frame cannot be set too deep to avoid damage when the car lights fall into it. When the storage frame is full of car lights, the staff needs to manually replace the storage frame. The patented storage frame is a hook-type design. When removing it, there are many car lights inside and the overall weight is heavy. It will consume a lot of effort to remove it, which increases the work intensity of the staff. In view of this, we propose an automobile car light airtightness detection machine. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) In the automobile lamp air tightness testing machine, when the storage frame is about to be full, the driving component drives the lifting frame to move in the vertical direction. After the lifting frame moves, the T-shaped slider and the T-shaped slot cooperate to drive the storage frame to move synchronously. During the descent of the storage frame, the locking component cooperates to unlock the limit block, and then the storage frame can be directly pulled away after it contacts the ground. Through the above structure, when the storage frame is replaced, it can be transported to the ground more conveniently, and when the storage frame is working, the T-shaped slider and the T-shaped slot can be used to lock its up and down movement, and the limit block can be used to cooperate with the locking component to lock its horizontal movement.

There is a support plate 11, and a driving component is arranged on the support plate 11. The detection component 2 and the transmission component 3 described in the text are both existing structures. For details, please refer to the patent publication number CN220239344U. When the interior of the storage frame 8 is about to be full, the lifting frame 6 is driven by the driving component to move in the vertical direction. After the lifting frame 6 moves, the storage frame 8 is driven to move synchronously by the cooperation of the T-shaped slider 9 and the T-shaped slot 7. In the process of the storage frame 8 descending, the limit block 10 is unlocked by the locking component, and then the storage frame 8 is directly pulled away after the storage frame 8 contacts the ground. Through the above structure, when the storage frame 8 is replaced, the storage frame 8 can be transported to the ground more conveniently, and when the storage frame 8 is working, the T-shaped slider 9 and the T-shaped slot 7 can be used to lock its up and down movement, and the limit block 10 can be used to cooperate with the locking component to lock its horizontal movement.

[0026] Furthermore, the locking assembly includes two sliding sleeves 12, which are fixedly connected to the front and rear side surfaces of the lifting frame 6 respectively, and the interiors of the two sliding sleeves 12 are respectively slidably sleeved with L-shaped locking rods 13, and the upper surface of the limit block 10 is provided with a positioning groove 14, and the positioning groove 14 is set to be conical, and the bottom wall of the positioning groove 14 is provided with a through groove 15, and the through groove 15 extends out of the lower side surface of the limit block 10, and the L-shaped locking rod 13 is adapted to the through groove 15. The outer surface of the L-shaped locking rod 13 is sleeved with a reset ring 16, and the upper side surface of the reset ring 16 is fixedly connected with a spring 17, and the upper end of the spring 17 is fixedly connected to the lower side surface of the sliding sleeve 12, and the front and rear A second limit block 18 is fixedly connected to the surface of the opposite side of the two supporting legs 4, and the driving assembly includes a motor 19, which is fixedly connected to the upper surface of the supporting plate 11, and a pulley 21 is fixedly connected to the output end of the motor 19. The upper and lower inner walls of the front and rear sliding grooves 5 are respectively rotatably connected with a threaded rod 22 and a limit rod 23, and the lifting frame 6 is slidably sleeved on the outer surface of the limit rod 23, and the lifting frame 6 is threadedly sleeved on the outer surface of the threaded rod 22. The outer surface of the threaded rod 22 is also sleeved with a pulley 21, and a second through groove is opened on the rear inner wall of the front sliding groove 5. A belt 24 is provided between the two pulleys 21. The lower surface of the storage frame 8 is provided with A roller 25 is arranged, and a second spring 26 is fixedly connected to the bottom wall of the storage frame 8. A rubber plate 20 is fixedly connected to the upper end of the second spring 26. The rubber plate 20 is slidably connected to the inner wall of the storage frame 8. When the headlight falls into the storage frame 8, it will first contact the rubber plate 20. The rubber plate 20 is forced to move downward and compress the second spring 26, and then the contraction of the second spring 26 is used to absorb part of the kinetic energy, thereby reducing the possibility of damage to the headlight. The motor 19 is used to cooperate with the two pulleys 21 and the belt 24 to drive the threaded rod 22 to rotate. Since the lifting frame 6 is limited in its movement trajectory by the limit rod 23, it will be synchronously driven to move vertically when the threaded rod 22 rotates. The L-shaped locking rod 13 contacts the upper surface of the second limit block 18 after the movement. At this time, the L-shaped locking rod 13 cannot move, and the storage frame 8 drives the limit block 10 to continue to move, so that the L-shaped locking rod 13 gradually disengages from the through slot 15. At the same time, the sliding sleeve 12 is still moving and will synchronously compress the spring 17. When the L-shaped locking rod 13 disengages from the through slot 15, the roller 25 contacts the ground. Through the above structure, not only can the rubber plate 20 and the second spring 26 be used to reduce the possibility of damage to the car light, but the roller 25 can also be used to facilitate the subsequent pulling of the storage frame 8. At the same time, it can automatically complete locking and unlocking to prevent the storage frame 8 from accidentally slipping in the air.

[0027] Working principle: When the storage frame 8 is about to be full, the lifting frame 6 is driven by the driving component to move in the vertical direction. After the lifting frame 6 moves, the storage frame 8 is driven to move synchronously by the cooperation of the T-shaped slider 9 and the T-shaped slot 7. During the descent of the storage frame 8, the limit block 10 is unlocked by the locking component. Then, after the storage frame 8 contacts the ground, the storage frame 8 can be directly pulled away. When the headlight falls into the storage frame 8, it will first contact the rubber plate 20. The rubber plate 20 is forced to move downward and compress the second spring 26, and then the contraction of the second spring 26 is used to absorb part of the kinetic energy, thereby reducing the possibility of damage to the headlight. The motor 19 cooperates with the two pulleys 21 and the belt 24 to drive the threaded rod 22 to rotate. Since the lifting frame 6 is limited in its movement trajectory by the limit rod 23, the threaded rod 22 will be synchronously driven to move in the vertical direction when it rotates. After the movement, the L-shaped locking rod 13 contacts the upper surface of the second limit block 18. At this time, the L-shaped locking rod 13 cannot move, and the storage frame 8 drives the limit block 10 to continue to move, so that the L-shaped locking rod 13 gradually disengages from the through slot 15. At the same time, the sliding sleeve 12 is still moving and will synchronously compress the spring 17. When the L-shaped locking rod 13 disengages from the through slot 15, the roller 25 contacts the ground.

[0028] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
