Description

Technical Field

[0001] This utility model relates to the field of spraying fixture technology, and in particular to a spraying fixture with a rotating structure. Background Technology

[0002] Spray painting fixtures are tools used in industrial manufacturing to fix and suspend parts or products that need to be painted. Since the workpieces need to be attached to the fixtures to complete pretreatment and spraying processes, they are an indispensable part of the coating production line and are widely used in many industrial fields such as automobile manufacturing, home appliance production, and surface treatment of mechanical equipment.

[0003] However, in order to spray the entire object, the hanger usually needs to be able to rotate. Most of the existing spraying hangers on the market are not easy to suppress the rotation of the hanger. As a result, when spraying a certain side, the object being sprayed is easy to rotate on its own, which affects the workers' spraying operation. In addition, the existing hangers on the market are not convenient for workers to adjust the hanging height of the hanger according to the height of the object being sprayed, and have low flexibility.

[0004] Therefore, those skilled in the art have provided a spraying fixture with a rotating structure to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a spraying hanger with a rotating structure. The fixed rod and the rotating rod in the rotating mechanism are rotatably connected, and the plug rod is engaged with the slot to easily restrict the rotation of the hanger. The threaded rod in the adjusting mechanism is threadedly connected to the telescopic rod, which can change the length of the telescopic rod and facilitate changing the suspension height of the hanger.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A spraying fixture with a rotating structure includes a moving track and a conveyor chain. A rotating mechanism is provided at the lower end of the moving track. The rotating mechanism includes multiple fixed rods, multiple rotating rods, and multiple return springs. The fixed rods are fixedly connected to the lower end of the conveyor chain at intervals. The lower ends of the fixed rods are rotatably connected to the rotating rods. The upper ends of the outer walls of the rotating rods are provided with multiple slots. The lower ends of the fixed rods are provided with sliding grooves. The rear ends of the return springs are fixedly connected with insert rods. The rear end of each insertion rod passes through a fixed rod and is engaged with a slot. The lower end of each rotating rod is provided with an adjustment mechanism, which includes multiple fixed cylinders and multiple threaded rods. The lower end of the outer wall of each rotating rod is fixedly connected to a fixed cylinder. The lower end of the outer wall of each threaded rod is threadedly connected to a telescopic rod. The lower end of each telescopic rod passes through a fixed cylinder and is fixedly connected to a hanging rod. The above technical solution uses a return spring to act on the insert rod, allowing the insert rod to engage with the slot on the rotating rod. This restricts the rotation of the rotating rod, suppressing the rotation of the hanger and preventing the object to be sprayed from rotating on its own. Furthermore, the threaded rod is threadedly connected to the telescopic rod, allowing the rotating threaded rod to move the telescopic rod and change the length of the telescopic rod extending out of the fixed cylinder, thus facilitating the adjustment of the hanger's suspension height.

[0007] Furthermore, multiple mounting blocks are fixedly connected at intervals on the upper end of the moving track, a sprocket groove is provided on the outer wall of the rear end of the moving track, and a connecting plate is slidably connected to the outer wall of the fixed rod body; The above technical solution allows the moving track to be fixed to the top of the workshop or other locations by mounting blocks that are fixedly connected at equal intervals on the upper end of the moving track. The sprocket grooves opened on the moving track allow the external sprockets to contact the conveyor chain, thereby enabling the external rotating sprockets to drive the conveyor chain. In addition, connecting plates are used to connect each fixed rod to form a whole, which can reduce the swaying between each fixed rod. The moving track and the conveyor chain are partially shown in the figure.

[0008] Furthermore, the inner wall of the front end of the slide is fixedly connected to the return spring, the insertion rod slides inside the slide, and the front end of the insertion rod passes through the fixed rod and is fixedly connected to the pull block; The above technical solution allows the insertion rod to remain engaged with the slot by the return spring acting on it, preventing the rotating rod from rotating on its own. By attaching a pull rope to the pull block, the operator can move the insertion rod inside the slide from a distance, changing the engagement state with the slot.

[0009] Furthermore, the upper end of the conveyor chain is fixedly connected with multiple fixed blocks at intervals, and the front and rear ends of each fixed block are rotatably connected with pulleys, which all roll inside the moving track. The above technical solution provides fixed points for the installation of pulleys by fixing blocks that are fixedly connected at equal intervals on the conveyor chain, and allows the pulleys to roll inside the moving track, which enables the conveyor chain to move stably within the moving track and provides support for the conveyor chain.

[0010] Furthermore, each threaded rod has a dial wheel fixedly connected to the upper end of its outer wall, each telescopic rod slides inside the fixed cylinder, and the upper end of each threaded rod is rotatably connected to the rotating rod. Through the above technical solution, the dial fixedly connected to the threaded rod allows the operator to easily rotate the threaded rod, thereby causing the telescopic rod to slide inside the fixed cylinder, changing the length of the telescopic rod extending out of the fixed cylinder, and allowing the upper end of the threaded rod to be rotatably connected to the rotating rod, enabling the threaded rod to rotate stably inside the fixed cylinder.

[0011] Furthermore, the front and rear ends of the upper part of the outer wall of the telescopic rod are fixedly connected to a limiting block, and the inner walls of the front and rear ends of the fixed cylinder are provided with limiting grooves, and the limiting grooves are slidably connected to the limiting block. The above technical solution provides guidance for the movement of the telescopic rod by sliding the limiting block fixedly connected to the telescopic rod and the limiting groove opened on the inner wall of the fixed cylinder, and prevents the telescopic rod from falling out of the inside of the fixed cylinder. At the same time, the limiting groove can also prevent the telescopic rod from rotating inside the fixed cylinder, so that the threaded rod can drive the telescopic rod to move normally.

[0012] This utility model has the following beneficial effects: 1. The present invention proposes a spraying hanger with a rotating structure. The fixed rod and the rotating rod in the rotating mechanism are rotatably connected, so that the hanger can drive the object to be sprayed to rotate. The return spring acts on the insertion rod, so that the insertion rod and the groove on the rotating rod are engaged, which can restrict the rotation of the rotating rod, thereby making it easier to suppress the rotation of the hanger, prevent the object to be sprayed from rotating on its own, and facilitate the spraying operation of the workers.

[0013] 2. The present invention proposes a spraying hanger with a rotating structure. By adjusting the threaded rod in the mechanism and the telescopic rod being threadedly connected, the rotating threaded rod can drive the telescopic rod to move, changing the length of the telescopic rod extending out of the fixed cylinder. This allows the operator to easily adjust the hanging height of the hanger according to the height of the object being sprayed, thus providing high flexibility. Attached Figure Description

The fixed rods 401 are fixedly connected to the lower end of the conveyor chain 3 at intervals. The lower ends of the fixed rods 401 are rotatably connected to the rotating rods 402. Multiple slots 403 are provided on the upper end of the outer wall of the rotating rods 402. The lower end of the fixed rods 401 is provided with a sliding groove 404. The rear end of each return spring 405 is fixedly connected to an insert rod 406. The rear end of each insert rod 406 passes through the fixed rod 401 and is engaged with the slot 403.

[0018] Multiple mounting blocks 2 are fixedly connected at intervals at the upper end of the moving track 1. A sprocket groove 7 is provided on the outer wall of the rear end of the moving track 1. Connecting plates 8 are slidably connected to the outer walls of the fixed rods 401. The moving track 1 can be fixed to the top of the workshop or other positions by the mounting blocks 2 fixedly connected at equal intervals at the upper end of the moving track 1. The sprocket groove 7 on the moving track 1 allows the external sprocket to contact the conveyor chain 3, so that the external rotating sprocket can drive the conveyor chain 3 to move. In addition, the connecting plates 8 connect each fixed rod 401 to form a whole, which can reduce the shaking between each fixed rod 401. The moving track 1 and the conveyor chain 3 are partially shown in the figure. The inner wall of the front end of the slide groove 404 is fixedly connected to the return spring 405. The insertion rods 406 slide inside the slide groove 404. The front end of the insertion rods 406 all penetrate through A fixed rod 401 is fixedly connected to a pull block 407. A return spring 405 acts on the insertion rod 406 to keep the insertion rod 406 engaged with the slot 403, preventing the rotating rod 402 from rotating on its own. A pull rope is attached to the pull block 407, allowing the operator to move the insertion rod 406 within the slide 404 from a distance, changing the engagement state with the slot 403. Multiple fixed blocks 5 are fixedly connected at intervals at the upper end of the conveyor chain 3. Pulleys 6 are rotatably connected to the front and rear ends of the fixed blocks 5. The pullleys 6 roll inside the moving track 1. The fixed blocks 5, which are fixedly connected at equal intervals on the conveyor chain 3, provide fixed points for the installation of the pullleys 6. The rolling of the pullleys 6 inside the moving track 1 allows the conveyor chain 3 to move stably within the moving track 1, providing support for the conveyor chain 3.

[0019] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5Each rotating rod 402 has an adjustment mechanism 9 at its lower end. The adjustment mechanism 9 includes multiple fixed cylinders 901 and multiple threaded rods 902. The lower end of the outer wall of the rotating rod 402 is fixedly connected to the fixed cylinder 901. The lower end of the outer wall of the threaded rod 902 is threadedly connected to a telescopic rod 904. The lower end of the telescopic rod 904 passes through the fixed cylinder 901 and is fixedly connected to a hanging rod 907. The upper end of the outer wall of the threaded rod 902 is fixedly connected to a dial wheel 903. The telescopic rod 904 slides inside the fixed cylinder 901. The upper end of the threaded rod 902 is rotatably connected to the rotating rod 402. The dial wheel 903 fixedly connected to the threaded rod 902 allows the operator to easily rotate the threaded rod 902, thereby causing the telescopic rod 904 to slide inside the fixed cylinder 901 and change the extension of the telescopic rod 904 out of the fixed cylinder. The length of 901 allows the upper end of the threaded rod 902 to be rotatably connected to the rotating rod 402, enabling the threaded rod 902 to rotate stably within the fixed cylinder 901. Limiting blocks 905 are fixedly connected to the front and rear ends of the upper part of the outer wall of the telescopic rod 904. Limiting grooves 906 are provided on the inner walls of the front and rear ends of the fixed cylinder 901, and these grooves 906 are slidably connected to the limiting blocks 905. By sliding the limiting blocks 905 fixed to the telescopic rod 904 and the limiting grooves 906 on the inner wall of the fixed cylinder 901, the movement of the telescopic rod 904 can be guided, preventing it from falling out of the fixed cylinder 901. Simultaneously, the limiting grooves 906 also prevent the telescopic rod 904 from rotating within the fixed cylinder 901, thus allowing the threaded rod 902 to normally drive the telescopic rod 904 to move.

[0020] Working principle: When using this spraying hanger with a rotating structure, the operator first uses the dial 903 to drive the threaded rod 902 to rotate, and uses the threaded rod 902 to connect with the telescopic rod 904 to change the length of the telescopic rod 904 extending out of the fixed cylinder 901, thereby changing the suspension height of the hanger to a suitable position. Next, the operator hangs the object to be sprayed on the hanging rod 907, and then uses an external motor to drive the sprocket, which in turn drives the conveyor chain 3 to move inside the moving track 1, transporting the object to be sprayed to the spraying point. Finally, the operator uses the spray gun to perform the spraying operation. At this time, under the action of the return spring 405, the insertion rod 406 remains engaged with the slot 403 to prevent the rotating rod 402 from rotating and to prevent the object to be sprayed from rotating on its own. By using the pull rope attached to the pull block 407, the insertion rod 406 is disengaged from the slot 403, allowing the operator to flip the object to be sprayed over and spray the back side.
