Description

Technical Field

[0001] The utility model relates to the technical field of vehicle body welding transportation, and more specifically, to a water flow transportation mechanism for vehicle body welding. Background Art

[0002] The assembly line transport mechanism for body welding mainly refers to a series of equipment and systems used to transport body parts, components or semi-finished products to be welded from one workstation to another on the body welding production line to ensure that the welding production process is carried out continuously and efficiently.

[0003] Generally, when welding a car body, you first need to place the car body on top of the moving plate, and then weld the car body. When the roller at the bottom of the device drives the moving plate forward, it will drive the car body forward. When it moves to the correct position, the motor will stop rotating, allowing the robot on the side to weld the car body. However, when the motor stops, due to the large weight of the car body, the inertia is greater. When the roller stops rotating, the car body will move forward a distance due to inertia, resulting in inaccuracy in the robot during welding, so it needs to be modified and optimized.

[0025] like Figures 1 to 7 As shown, the utility model provides a flow conveying mechanism for body welding, comprising a bracket 1, a platform 2, a baffle 3, and a bottom plate 6, wherein the platform 2 is fixedly arranged above the bracket 1, the baffle 3 is fixedly arranged above the platform 2, the bottom plate 6 is fixedly arranged on the side of the bracket 1, and a movable plate 20 is movably installed above the platform 2;

[0026] A fixing mechanism is rotatably installed on the side of the bracket 1, and the fixing mechanism includes a connecting rod 2 19 rotatably arranged on the side of the bracket 1, a roller 3 13 is fixedly sleeved on the upper part of the connecting rod 2 19, a gear 17 is fixedly sleeved on the upper part of the connecting rod 2 19, a fixing plate 14 is fixedly installed on the bottom of the platform 2, a spring 15 is fixedly installed on one side of the fixing plate 14, a top plate 16 is fixedly installed on one end of the spring 15, and a clamping plate 18 is fixedly installed on one end of the movable plate 20.

[0027] When the staff uses it, the staff first starts the motor 4. When the motor 4 is started, it will drive the rotation of roller 15. When roller 15 rotates, it will drive roller 2 8 to rotate through belt 1 7. When roller 2 8 rotates, it will drive connecting rod 1 9 to rotate. When connecting rod 1 9 rotates, it will drive the moving wheel 10 to rotate. When roller 2 8 rotates, it will drive gear 17 to rotate through belt 2 11. As the moving wheel 10 rotates, the moving plate 20 will be driven to move to the correct position. At this time, the motor 4 will stop, and the spring 15 will generate a push force on the top plate 16. At this time, the top plate 16 will generate a push force on the gear 17, which will prevent the gear 17 from rotating. When the card plate 18 contacts the gear 17, it will stop moving.

[0028] A top force is applied to the top plate 16 through the spring 15, so that the top plate 16 limits the rotation of the gear 17. When the clamping plate 18 contacts the gear 17, it stops rotating. Compared with the traditional device, the device can stop the moving plate 20 in time when it moves to the correct position through the cooperation between the gear 17 and the clamping plate 18, avoiding the inevitable movement of the moving plate 20, which would lead to inaccurate welding of the car body, thereby improving the accuracy of welding and thus improving the working efficiency of the device.

[0030] When the staff uses it, they first place the car body to be welded on top of the movable plate 20, and then turn the handle 23. When the handle 23 is turned, the threaded rod 22 will be rotated. When the threaded rod 22 is rotated, since the connection between the fixed block 21 and the threaded rod 22 is provided with threads, as the threaded rod 22 rotates, the threaded rod 22 will move forward. When the threaded rod 22 moves forward, it will drive the protrusion 25 to move forward. When the protrusion 25 moves forward, it will drive the clamping plate 24 to move forward. When the clamping plate 24 moves to the surface of the car body, it will clamp and fix the car body.

[0031] By placing the body to be welded on top of the movable plate 20 and then turning the handle 23, the threaded rod 22 will be driven to move forward as the handle 23 turns, and when the threaded rod 22 moves forward, the clamping plate 24 will be driven to move forward, thereby clamping the body. Compared with the traditional device, the device drives the clamping plate 24 to move forward through the cooperation between the threaded rod 22 and the fixed block 21, thereby clamping and fixing the body, improving the stability of the body during welding, thereby improving the working efficiency of the device.

[0032] Among them, a transmission mechanism is fixedly installed above the bottom plate 6, and the transmission mechanism includes a motor 4 fixedly arranged at the bottom of the bottom plate 6. A roller 5 is fixedly installed above the transmission of the motor 4, and a belt 7 is movably sleeved above the roller 5.

[0033] By starting the motor 4, when the motor 4 is started, the roller 1 5 will be driven to rotate, and when the roller 1 5 rotates, the roller 2 8 will be driven to rotate through the belt 1 7.

[0035] The rotation of the roller 2 8 will drive the connecting rod 1 9 to rotate, and when the connecting rod 1 9 rotates, the moving wheel 10 will be driven to rotate, thereby driving the moving plate 20 to move forward.

[0036] There are four rollers 2 8 and four connecting rods 1 9 in the transport mechanism, and a belt 2 11 is connected between every two rollers 2 8 for transmission.

[0037] The movable plate 20 can be moved smoothly above the platform 2, thereby improving the stability of the movement of the movable plate 20.

[0038] Among them, two moving wheels 10 are fixedly sleeved on the top of the connecting rod 1 9 , and each moving wheel 10 is evenly distributed on the top of the connecting rod 1 9 .

[0041] The movable plate 20 can be driven to move forward above the platform 2 by the rotation of the movable wheels 10 .

[0042] The working principle and use process of this utility model:

[0043] When the staff uses it, the staff first starts the motor 4. When the motor 4 is started, it will drive the rotation of roller 15. When roller 15 rotates, it will drive roller 2 8 to rotate through belt 1 7. When roller 2 8 rotates, it will drive connecting rod 1 9 to rotate. When connecting rod 1 9 rotates, it will drive the moving wheel 10 to rotate. When roller 2 8 rotates, it will drive gear 17 to rotate through belt 2 11. As the moving wheel 10 rotates, the moving plate 20 will be driven to move to the correct position. At this time, the motor 4 will stop, and the spring 15 will generate a push force on the top plate 16. At this time, the top plate 16 will generate a push force on the gear 17, which will prevent the gear 17 from rotating. When the card plate 18 contacts the gear 17, it will stop moving.

[0044] When the staff uses it, they first place the car body to be welded on top of the movable plate 20, and then turn the handle 23. When the handle 23 is turned, the threaded rod 22 will be rotated. When the threaded rod 22 is rotated, since the connection between the fixed block 21 and the threaded rod 22 is provided with threads, as the threaded rod 22 rotates, the threaded rod 22 will move forward. When the threaded rod 22 moves forward, it will drive the protrusion 25 to move forward. When the protrusion 25 moves forward, it will drive the clamping plate 24 to move forward. When the clamping plate 24 moves to the surface of the car body, it will clamp and fix the car body.
