Description

Technical Field

[0001] This utility model relates to the field of parts spraying technology, specifically to a surface spraying device for bent plate components. Background Technology

[0002] Automotive parts manufacturing spraying equipment is a device used for spraying automotive parts, and it is widely used in the field of automotive parts manufacturing.

[0003] The utility model patent with authorization announcement number CN211964745U discloses a spraying device for automobile parts production, including a housing, a parts placement door, a parts placement door handle, a diversion bend, a hollow shaft, a guide sleeve, a first motor, a partition, a clamping device, a paint tank, a filter box, a first pipe, a suction pump, and a second pipe. The housing has a spraying chamber inside, and two openings are provided at the left end of the housing. The parts placement door is installed at the upper opening on the left end of the housing, and the parts placement door handle is installed on the parts placement door. Multiple sets of nozzles are provided on the diversion bend. The output end of the hollow shaft is connected to the input end of the diversion bend. Multiple sets of holes are provided on the hollow shaft. The guide sleeve is fitted on the hollow shaft and communicates with the hollow shaft through the holes. The guide sleeve and the hollow shaft are rotatably and sealingly connected. The hollow shaft passes through the top of the housing and is connected to the output end of the first motor. The first motor is installed at the top of the housing.

[0004] As shown in the above utility model, the clamping device of the existing spraying device adopts a planar clamping structure of a fixed clamping plate and a movable clamping plate, and clamping is achieved by pushing the movable clamping plate to move linearly through a cylinder. However, for the arc-shaped surface of the bent plate parts, the clamping plate cannot fit the curved surface contour, resulting in local stress concentration or gaps during clamping. The parts are prone to shaking during the spraying process, resulting in uneven coating thickness. At the same time, the spraying mechanism drives the diversion bend to rotate through the hollow shaft, and the nozzle can only make circular motion and lacks lateral movement function. For parts whose width exceeds the length of the diversion bend, the edge area is beyond the coverage range of the nozzle rotation, resulting in the side areas not being sprayed, requiring manual touch-up spraying, which reduces efficiency.

[0017] Beneficial effects

[0018] This invention provides a surface spraying device for curved plate components. Compared with the prior art, it has the following advantages:

[0019] 1. This equipment for spraying the surface of curved plate parts has a movable clamping component that drives the connecting plate to move via a telescopic cylinder.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides two technical solutions:

[0029] First implementation: A surface spraying device for curved plate components, comprising a housing 1, a fixed clamping component 2, and a movable clamping component 3.

[0030] Specifically, the front of the box body 1 is connected to a door 11 via hinges and latches. The door 11 is connected via 304 stainless steel hinges and equipped with a mechanical latch. A storage tank 12 is installed at the bottom of the box body 1, with a built-in agitator to prevent paint sedimentation. A collection hopper 13 is installed at the lower end of the inner cavity of the box body 1. The collection hopper 13 is in the shape of an inverted trapezoidal funnel. Two symmetrically distributed guide rods 131 are fixed to the top of both sides of the upper surface of the collection hopper 13. A spring 132 is sleeved on the outer side of the lower end of the guide rods 131. A filter screen frame 133 is installed inside the collection hopper 13. The filter screen frame 133 is a rectangular frame structure with a pore size of 0. The filter screen is made of 3-0.5mm stainless steel. Both sides of the filter screen frame 133 have L-shaped extension plates 134 fixed to the upper center. The top of each extension plate 134 has two guide holes 135 that match the guide rods 131. A protruding plate 136 is fixed to the lower outer side of the extension plate 134, facilitating lifting and replacement of the filter screen frame 133. A spring 132 supports the extension plate 134, keeping the filter screen frame 133 horizontal. When paint drips from the spraying area into the collection hopper 13, large particles (such as paint chips and dust) are intercepted by the filter screen, and the clean paint flows through the filter screen into the storage tank 12. To remove impurities, simply pull up the protruding plate 136 to remove the filter screen frame 133, clean it, and then return it to its original position.

[0031] A fixed baffle 137 is fixed to the top of one end of the collecting hopper 13, and a slot 138 is opened at the other end. A movable baffle 139 is inserted into the slot 138. The fixed baffle 137 and the movable baffle 139 are used to guide the spray paint thrown out by the curved plate parts during rotation. The inner sides of the fixed baffle 137 and the movable baffle 139 are smooth curved surfaces, forming a guide channel to guide the splashed paint to slide down the baffles to the top of the filter screen frame 133. A screw groove 1310 is opened in the middle of the other end of the collecting hopper 13. The 10 is connected to a limit knob 1311 via internal and external threads. The knob head is provided with anti-slip texture for easy manual adjustment. The limit knob 1311 is used to limit the movable baffle 139. After the movable baffle 139 is adjusted to the appropriate position, the limit knob 1311 is rotated clockwise so that its end is pressed against the outer wall of the movable baffle 139 to fix the movable baffle 139. When placing or removing the bent plate parts, the movable baffle 139 can be quickly disassembled by loosening the limit knob 1311 counterclockwise without affecting the removal of the bent plate parts.

[0032] Specifically, the collection hopper 13 is connected to the storage tank 12, and the storage tank 12 is connected to the spraying mechanism inside the box 1. The spraying mechanism inside the box 1 includes a transverse guide rail 14 fixed at the upper end of the inner cavity of the box 1, which is a synchronous belt linear module. The output end of the transverse guide rail 14 is connected to a distribution plate 15. The distribution plate 15 is connected to the storage tank 12 through a connecting pipe. Multiple equally spaced nozzles 16 are installed on the lower surface of the distribution plate 15. The nozzles 16 are air atomizing nozzles.

[0033] More specifically, the fixed clamping component 2 is located on one side of the inner cavity of the housing 1, and a drive mechanism is provided on it to drive the bent plate parts to rotate. The fixed clamping component 2 includes a drive motor 21 fixed on the outer wall of one side of the housing 1. The drive motor 21 is a three-phase asynchronous motor. The output end of the drive motor 21 is rigidly connected to the transmission shaft 22 through a coupling. One end of the transmission shaft 22 passes through the side wall of the housing 1 and is inserted into the housing 1. A fixed clamping plate 23 is fixed to one end of the transmission shaft 22. A connecting sleeve 24 is movably connected to the outer side of one end of the transmission shaft 22 through a bearing. A support rod 25 is fixed to the bottom end of the connecting sleeve 24. The support rod 25 is set as an inclined structure, and the lower end of the support rod 25 is fixed to the inner wall of one side of the housing 1 to form a triangular support structure to ensure the stability of the transmission shaft 22 when rotating.

[0034] The second embodiment differs from the first embodiment in that: the movable clamping member 3 is located on the other side of the inner cavity of the housing 1. The movable clamping member 3 cooperates with the fixed clamping member 2 to clamp and limit the bent plate parts. The movable clamping member 3 is provided with a telescopic mechanism for clamping bent plates of different widths. The movable clamping member 3 includes a telescopic cylinder 31 fixed on the outer wall of the other side of the housing 1. The output shaft of the telescopic cylinder 31 is fixed with a connecting plate 32. One side of the connecting plate 32 is movably connected to a movable clamping plate 34 through a rotary bearing. The movable clamping plate 34 corresponds to the fixed clamping plate 23. The other edge of the connecting plate 32 is connected to the inner wall of the other side of the housing 1 through multiple telescopic rods 33 arranged in a circular array to eliminate lateral forces during movement and ensure a smooth and uninterrupted clamping process, thereby maintaining the stable movement of the connecting plate 32.

[0035] When this device is in operation, first open the box door 11, place the bent plate part between the fixed clamping plate 23 and the movable clamping plate 34, close the box door 11, and simultaneously start the telescopic cylinder 31. The telescopic cylinder 31 drives the connecting plate 32 to move horizontally. Multiple telescopic rods 33 on the edge of the connecting plate 32 are connected to the inner wall of the box body 1 to ensure straightness during movement. When the telescopic cylinder 31 pushes the movable clamping plate 34 close to the fixed clamping plate 23, the two cooperate to clamp the bent plate part. After clamping, move the movable baffle 139 upward until the movable baffle 139 and the fixed baffle 137 form a guide channel. Then rotate the limit knob 1311 clockwise so that its end abuts against the outer wall of the movable baffle 139 to fix the movable baffle 139. Then start the drive motor 21. The drive motor 21 drives the transmission shaft 22 to rotate at a speed of 5-10 r / min, so that the bent plate part rotates at a uniform speed around the axis, ensuring that all parts of the surface can be exposed under the nozzle 16 during spraying. The guide channel formed by the fixed baffle 137 and the movable baffle 139 directs the splashed paint to the center of the collection hopper 13, preventing paint from adhering to the inner wall of the housing 1. The paint in the storage tank 12 is pumped to the distribution plate 15 through the connecting pipe. The nozzles 16 evenly distributed on the lower surface of the distribution plate 15 atomize and spray the paint. The transverse guide rail 14 drives the distribution plate 15 to move back and forth along the width direction of the housing 1, covering the entire width range of the curved part and ensuring uniform adhesion of the atomized particles. When the part rotates one revolution and the distribution plate 15 completes one reciprocating movement, uniform spraying of the entire surface can be achieved. For complex curved surfaces, the matching relationship between the guide rail movement speed and the part rotation speed can be adjusted by the control system to avoid coating accumulation or missed spraying. The collection hopper 13 at the bottom of the box 1 is funnel-shaped. During the spraying process, the unattached paint slides down the inner wall of the box 1 to the collection hopper 13. After being filtered by the filter screen frame 133, the impurities are retained above the filter screen. The clean paint flows back to the storage tank 12 through the bottom pipe. The buffering effect of the spring 132 prevents the filter screen frame from sinking due to the impact of the paint, ensuring the filtration efficiency. At the same time, it reduces paint splashing caused by vibration, reduces waste and avoids environmental pollution. After the spraying is completed, all moving parts are stopped, and the box door 11 is opened to take out the parts.
