Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal spraying equipment, in particular to a surface spraying mechanism for a sheet metal turning frame. Background Art

[0002] In the context of existing sheet metal spraying technology, it has always been a technical challenge to spray evenly on sheet metal parts with complex shapes or large sizes. Traditional spraying equipment is limited by its mechanical structure and adjustment capabilities. When spraying such sheet metal parts, it is often difficult to ensure that the paint can evenly cover all surfaces, especially those with irregular shapes or obstructed areas. The position and angle adjustment of the nozzle are not flexible enough, which often leads to poor spraying effects, mottled, missing or overlapping problems. This not only affects the appearance quality of the product, but may also reduce its anti-corrosion performance and service life.

[0003] In order to solve these problems, the industry has tried to improve the spraying effect by increasing the number of nozzles, optimizing the spraying path, etc. However, these methods are often limited in effect in practical applications and may increase the complexity and maintenance cost of the equipment. Therefore, developing a new type of spraying mechanism that can accurately and flexibly adjust the position and angle of the nozzle has become a key technical requirement for improving the quality of sheet metal spraying. In view of this, we propose a surface spraying mechanism for a sheet metal flip rack. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The surface spraying mechanism of the sheet metal turning frame includes a base 1, a top plate 4 located directly above the base 1, and a nozzle 9 for spraying paint. A movable plate 3 that can move up and down is provided between the base 1 and the top plate 4. A clamping mechanism 2 is rotatably installed at the bottom of the movable plate 3 and the top of the base 1. A U-shaped bracket 6 for supporting the top plate 4 is fixedly installed on the top of the base 1. An adjustment mechanism 8 that can move up and down is provided in the U-shaped bracket 6. The adjustment mechanism 8 includes a U-shaped mounting plate 80. A movable block 83 with an adjustable position is provided in the U-shaped mounting plate 80. An electric telescopic rod 84 is embedded and installed on the movable block 83. A fixed disk 85 is fixed to the end of the piston rod of the electric telescopic rod 84. A rotating motor 86 is fixedly installed at the bottom of the fixed disk 85. The nozzle 9 is fixed to the output shaft of the rotating motor 86. By designing a device including a base 1, a top plate 4, a movable plate 3, a clamping mechanism 2 and a spraying mechanism, the sheet metal parts can be effectively fixed, and the sheet metal parts can be adjusted at multiple angles in three-dimensional space through the up and down movement of the movable plate 3 and the flipping function of the clamping mechanism 2, thereby meeting all-round spraying requirements. At the same time, the spraying mechanism can achieve precise adjustment of the height and position of the spray head 9 through the cooperation of the U-shaped bracket 6 and the adjustment mechanism 8, further improving the accuracy and flexibility of the spraying. In addition, the setting of the rotating motor 86 allows the spray head 9 to rotate during the spraying process, so that the paint can be sprayed more evenly on the surface of the sheet metal part.

[0025] As a preferred embodiment of the present invention, the clamping mechanism 2 includes a turntable 20, on which two fixed plates 21 and two clamping plates 23 are symmetrically fixedly mounted, and each fixed plate 21 is mounted with a second hydraulic cylinder 22 for driving the clamping plates 23 to move. The design of the clamping mechanism 2 enables the sheet metal to be firmly fixed on the turntable 20, and the clamping plates 23 are driven to move by the second hydraulic cylinder 22, so that sheet metals of different sizes and shapes can be accommodated, thereby improving the versatility and practicality of the spraying equipment.

[0026] As a preferred embodiment of the present invention, a flip motor 30 for driving the turntable 20 to rotate is installed on the movable plate 3, and a first hydraulic cylinder 5 for driving the movable plate 3 to move up and down is installed on the top plate 4. The setting of the flip motor 30 enables the clamping mechanism 2 to drive the sheet metal to flip, and with the up and down movement of the movable plate 3, the sheet metal can be adjusted at multiple angles in space, which is convenient for comprehensive spraying. At the same time, the driving of the first hydraulic cylinder 5 makes the movement of the movable plate 3 more stable and precise.

[0027] As a preferred embodiment of the present invention, a threaded rod 60 extending from the top of the U-shaped bracket 6 is fixed to the top of the adjustment mechanism 8, and a knob 62 threadably connected to the threaded rod 60 is rotatably mounted on the top of the U-shaped bracket 6. Through the cooperation of the threaded rod 60 and the knob 62, the height of the adjustment mechanism 8 and the nozzle 9 can be adjusted.

[0028] As a preferred embodiment of the present invention, a driven gear 61 is fixedly mounted on the outer ring wall of the knob 62, a driving gear 63 is meshed on one side of the driven gear 61, and a driving motor 64 is mounted on the U-shaped bracket 6 to drive the driving gear 63 to rotate. Through the cooperation of the driven gear 61, the driving gear 63 and the driving motor 64, the automatic lifting and lowering of the spray head 9 can be realized, further improving the efficiency and accuracy of spraying.

[0029] As a preferred embodiment of the present invention, an adjusting screw 81 is rotatably mounted in the U-shaped mounting plate 80, a movable block 83 is threadedly connected to the adjusting screw 81, and an adjusting motor 82 for driving the adjusting screw 81 to rotate is mounted on the outer wall of the U-shaped mounting plate 80. The threaded connection between the adjusting screw 81 and the movable block 83 allows the movable block 83 to move precisely in the U-shaped mounting plate 80, thereby driving the nozzle 9 to adjust its position.

[0030] As a preferred embodiment of the present invention, the outer wall of the U-shaped mounting plate 80 away from the adjusting motor 82 is closely fitted with the inner wall of the U-shaped bracket 6. The close fit between the U-shaped mounting plate 80 and the inner wall of the U-shaped bracket 6 ensures the stability and accuracy of the spraying mechanism and avoids the spraying effect being affected by the shaking of the equipment during the spraying process.

[0031] As a preferred embodiment of the present invention, a separate spraying liquid barrel 7 is further included, and the spraying liquid barrel 7 is connected to the spray head 9 through a hose. The separate spraying liquid barrel 7 is connected to the spray head 9 through a hose, which ensures the continuous supply of the spraying liquid and also makes the spraying process more flexible and convenient. The design of the spraying liquid barrel 7 is also convenient for replacing and replenishing the spraying liquid, which improves the continuity and efficiency of the spraying operation.

[0032] When the surface spraying mechanism of the sheet metal flip frame of the utility model is used, first, the operator adjusts the distance between the two clamping mechanisms 2 through the first hydraulic cylinder 5 according to the height of the sheet metal, and then places the sheet metal on the turntable 20, and drives the clamping plate 23 to move by controlling the extension and contraction of the second hydraulic cylinder 22, so that the sheet metal is firmly clamped on the turntable 20. When the sheet metal needs to be flipped, the flip motor 30 will drive the turntable 20 to rotate to achieve flipping, and the drive motor 64 can be started to drive the knob 62 to rotate through gear transmission, thereby driving the threaded rod 60 to move up and down to adjust the height of the nozzle 9. During the spraying process, the adjustment motor 82 drives the adjustment screw 81 to rotate, so that the movable block 83 moves accurately in the U-shaped mounting plate 80, thereby driving the nozzle 9 to move to a suitable position; the electric telescopic rod 84 can fine-tune the distance between the nozzle 9 and the sheet metal, and the rotary motor 86 drives the nozzle 9 to rotate for uniform spraying. The spraying liquid is transported to the nozzle 9 by the spraying liquid barrel 7 through a hose. After spraying is completed, the components are reset to prepare for the next sheet metal part to be sprayed.
