Description

Technical Field

[0001] The utility model relates to the technical field of automobile engines, in particular to a stopper for an automobile engine assembly line. Background Art

[0002] As a key component with the most intensive technology in the field of automobiles, the engine faces many challenges during the assembly process of automobile engines. Due to the diversity of the parts to be assembled and the extremely cumbersome process, and the pallet is an important part of the assembly line. During the pallet conveying on the engine assembly line, when the pallet shifts on the assembly line, a stopper for the automobile engine assembly line is usually used to block it.

[0003] However, after the existing stopper for the automobile engine assembly line jacks up the pallet to separate it from the conveying line, it often needs to be further lifted to a higher position for assembly processing close to the operator. At this time, the pallet is only supported by the relatively small supports on the stopper, and the stability is significantly insufficient. This easily leads to the pallet and the workpiece falling. On the one hand, it will cause damage to the workpiece and bring greater economic losses; on the other hand, if it hits the operator's foot, it may also cause industrial injury accidents. To effectively solve the above problems, a new type of stopper for the automobile engine assembly line is specifically proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a stopper for an automobile engine assembly line is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A stopper for an automobile engine assembly line includes a conveying line and a moving plate. An installation frame is installed on the conveying line. A lifting plate is provided on the installation frame through a cylinder. A fixed frame is fixedly provided on the lifting plate. A threaded sleeve is rotatably provided on the lifting plate. A lifting screw is threadedly installed in the threaded sleeve. A top plate is installed on the lifting screw. A driving motor is provided on the lifting plate. The driving motor is connected to the threaded sleeve through a rotating mechanism. A synchronous gear is rotatably provided on the lifting plate. The synchronous gear is connected to the threaded sleeve through a linkage mechanism. A moving screw is provided on the lifting plate through a support plate. The moving screw is connected to the synchronous gear through a synchronous mechanism. A movable frame is threadedly installed on the moving screw.

[0007] Preferably, the rotating mechanism includes a driving gear provided on the output shaft of the driving motor, and a transmission gear meshing with the driving gear is provided on the threaded sleeve.

[0008] Preferably, the linkage mechanism includes a linkage gear installed on the synchronous gear, and the linkage gear meshes with the transmission gear.

[0009] Preferably, the synchronization mechanism includes a moving gear installed on the support plate, and the moving gear meshes with a synchronization gear.

[0010] Preferably, two first limiting rods are installed at the bottom of the lifting plate, and both of the two first limiting rods slidably penetrate through the mounting frame.

[0011] Preferably, a second limiting rod is installed at the bottom of the top plate, and the second limiting rod slidably penetrates through the lifting plate.

[0012] Preferably, a limiting block is installed at the bottom of the movable frame, and a limiting groove corresponding to the limiting block is provided on the upper end surface of the lifting plate.

[0013] Preferably, protective pads are provided on the surfaces of the movable frame and the fixed frame corresponding to the moving plate, and the protective pads are made of rubber.

[0014] Preferably, the driving gear, the transmission gear and the linkage gear are all circular gears, and the synchronization gear and the moving gear are both bevel gears.

[0015] The beneficial effects of the present utility model are as follows:

[0018] 3. As the height of the moving plate rises, the movable frame and the fixed frame cooperate to clamp the moving plate to ensure its stability after the height rises; when the moving plate descends, the clamping is released to flexibly adapt to different assembly stages.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Referring to Figures 1-6 , a blocker for an automobile engine assembly line plays a crucial role in the process of assembling an automobile engine. The conveyor line 1 undertakes the important task of conveying workpieces, and its stable operation ensures that engine components can flow orderly between various assembly stations. The moving plate 2 is the object acted upon by the blocker, and its movement on the conveyor line 1 needs to be precisely controlled.

[0028] The mounting frame 4 is firmly mounted on the conveyor line 1, providing stable support for the entire blocker structure.

[0029] The cylinder 8 is mounted on the mounting frame 4, and its telescopic movement can precisely control the height of the lifting plate 9. When the cylinder 8 extends, the lifting plate 9 is lifted, driving the components thereon to rise; when the cylinder 8 contracts, the lifting plate 9 descends to its initial position.

[0030] Two first limiting rods 7 are mounted at the bottom of the lifting plate 9, and they slide through the mounting frame 4, ensuring that the lifting plate 9 always moves stably in the vertical direction during the lifting process without shaking or deviation.

[0031] On the lifting plate 9, the fixing frame 6 plays a role in fixing and supporting. The driving motor 10 serves as the power source and is connected to the threaded sleeve 11 through a rotating mechanism. The driving gear 15 in the rotating mechanism is installed on the output shaft of the driving motor 10. When the driving motor 10 starts, the driving gear 15 rotates accordingly. The transmission gear 16 on the threaded sleeve 11 meshes with the driving gear 15, thereby transmitting the power of the driving motor 10 to the threaded sleeve 11 and causing it to rotate. The lifting screw 13 is installed with internal threads in the threaded sleeve 11. When the threaded sleeve 11 rotates, the lifting screw 13 will rise or fall according to the rotation direction of the threaded sleeve 11.

[0032] The top plate 12 is installed on the lifting screw 13 and moves along with the movement of the lifting screw 13. To ensure the stable lifting of the top plate 12, a second limiting rod 14 is installed at the bottom of the top plate 12. The second limiting rod 14 slides through the lifting plate 9, preventing the top plate 12 from rotating or shifting during the lifting process.

[0033] The synchronous gear 19 is installed on the lifting plate 9 and can rotate, and is connected to the threaded sleeve 11 through a linkage mechanism. The linkage gear 18 in the linkage mechanism is installed on the synchronous gear 19 and meshes with the transmission gear 16. In this way, when the threaded sleeve 11 rotates, through the meshing of the linkage gear 18 and the transmission gear 16, the synchronous gear 19 will also rotate accordingly. The support plate 17 is installed on the lifting plate 9 to provide support for the moving screw 21. The moving screw 21 is connected to the synchronous gear 19 through a synchronous mechanism. The moving gear 20 in the synchronous mechanism is installed on the support plate 17 and meshes with the synchronous gear 19. When the synchronous gear 19 rotates, the moving gear 20 will also rotate, thereby driving the moving screw 21 to rotate. The movable frame 5 is installed with threads on the moving screw 21. When the moving screw 21 rotates, the movable frame 5 will move horizontally according to the rotation direction of the moving screw 21.

[0034] The limiting block 22 at the bottom of the movable frame 5 cooperates with the limiting groove 23 on the upper end surface of the lifting plate 9 to ensure that the movable frame 5 remains stable during the movement and will not deviate from the track.

[0035] Protective pads are provided on the corresponding surfaces of the movable frame 5 and the fixing frame 6 facing the moving plate 2. The protective pads are made of rubber material, which can effectively protect the surface of the moving plate 2 from being scratched or damaged. At the same time, the rubber material protective pads also have a certain elasticity, which can play a buffering role when blocking the moving plate 2 and reduce the impact force.

[0036] The driving gear 15, the transmission gear 16 and the linkage gear 18 are all circular gears. This form of gear can ensure the smooth transmission of power and precise meshing. The synchronous gear 19 and the moving gear 20 are both bevel gears. The characteristic of bevel gears is that they can change the direction of power transmission, enabling the horizontal moving screw 21 to achieve synchronous movement with the vertical threaded sleeve 11.

[0037] When the utility model is in use, when it is necessary to block the moving plate 2 on the conveyor line 1, the cylinder 8 extends to push the lifting plate 9 to rise. Finally, the top plate 12 contacts the bottom wall of the moving plate 2, and the side wall of the moving plate 2 contacts the outer wall of the fixed frame 6 to achieve blocking and support.

[0038] When the height of the moving plate 2 needs to be lifted so that the height of the workpiece in the placement groove 3 is too high, the drive motor 10 is started, and the driving gear 15 on the output shaft of the drive motor 10 rotates. The driving gear 15 meshes with the transmission gear 16 on the threaded sleeve 11 to drive the threaded sleeve 11 to rotate. The lifting screw 13 in the threaded sleeve 11 rises as the threaded sleeve 11 rotates, and the top plate 12 can drive the moving plate 2 to rise without disengaging from the fixed frame 6.

[0039] Meanwhile, while the threaded sleeve 11 rotates, through the meshing of the linkage gear 18 and the transmission gear 16, the synchronous gear 19 is driven to rotate. The synchronous gear 19 meshes with the moving gear 20 on the support plate 17 to make the moving gear 20 rotate, and then drives the moving screw 21 to rotate. The movable frame 5 on the moving screw 21 moves towards the moving plate 2 under the action of the thread. Finally, in cooperation with the fixed frame 6, the moving plate 2 is clamped.

[0040] To sum up, that is, after the moving plate 2 is lifted and separated from the conveyor line 1, it can rise again in height. And as its height rises, the movable frame 5 cooperates with the fixed frame 6 to clamp the moving plate 2 to ensure its stability after the height rises. Similarly, the clamping is released when the moving plate 2 descends.

[0041] The above is only the preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the utility model.
