Description

Technical Field

[0001] This utility model belongs to the field of prototype model processing technology, and in particular relates to a spraying device for prototype models. Background Technology

[0002] With the rapid development of the manufacturing industry, prototype models are a key link in product development, appearance verification and functional testing. The precision and efficiency of their surface treatment processes are receiving increasing attention. Spraying, as the core process of prototype model surface treatment, directly affects the appearance, texture, corrosion resistance and detail reproduction of the model. Especially in the fields of industrial design prototypes and precision parts samples, higher requirements are placed on the uniformity of spraying, the consistency of coating thickness and the ability to cover complex curved surfaces.

[0003] However, in the use of existing spraying devices for prototype models, the position of the prototype model is prone to shift, which affects the uniformity of the spraying and reduces the spraying efficiency, thus affecting the processing efficiency of the prototype model. Utility Model Content

[0004] The purpose of this utility model is to provide a spraying device for prototype models. By setting a clamping mechanism, it solves the problem that in the existing spraying devices for prototype models, the position of the prototype model is easily shifted during use, which affects the uniformity of the spraying and thus reduces the spraying efficiency and affects the processing efficiency of the prototype model.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a spraying device for hand-made models, including a base, on which a rotating mechanism and a clamping mechanism are provided;

[0007] The rotating mechanism includes a rectangular cover fixedly connected to the top of the base, and a motor fixedly connected to the bottom of the base. The clamping mechanism includes a rectangular box set on the top of the base, and fixed rods are rotatably connected to the left inner wall and the right inner wall of the rectangular box. Two hinge rods are hinged to each of the two fixed rods.

[0008] Furthermore, a support frame is fixedly connected to the outer wall of the base, a bracket is fixedly connected to the top of the support frame, and a plurality of nozzles are connected to the top of the bracket.

[0009] Furthermore, a rotating shaft passes through the central axis of the base, the rotating shaft is rotatably connected to the base, the top of the rotating shaft passes through a rectangular cover and extends outward, the output shaft of the motor is fixedly connected to the rotating shaft through a coupling, a circular plate is fixedly connected to the outer wall of the rotating shaft, and the top of the circular plate is fixedly connected to the rectangular box.

[0010] Furthermore, two sliding rods are fixedly connected inside the rectangular box, and two movable supports are slidably connected to the outer walls of the two sliding rods. Fixed blocks are fixedly connected to the left and right sides of the two movable supports, and several fixed blocks are respectively hinged to several hinge rods.

[0011] Furthermore, a hydraulic cylinder is fixedly connected to the inner front wall of the rectangular box, and the rear side of the hydraulic cylinder is fixedly connected to a movable bracket located on the front side.

[0012] Furthermore, the top of the rectangular box is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to two fixed plates. The bottom of the two fixed plates is fixedly connected to the top of the two movable supports respectively, and a buffer pad is fixedly connected to the side of the two fixed plates that are close to each other.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting up a rotating mechanism, several nozzles on the bracket spray the prototype model. Then, the motor is started. At this time, the motor drives the rotating shaft to rotate at the central axis of the base and the rectangular cover through the coupling. When the rotating shaft rotates, it drives the circular plate to rotate. Through the fixed connection between the circular plate and the rectangular box, the rectangular box is driven to rotate. The rotation of the rectangular box drives the prototype model to rotate, which improves the uniformity of spraying. After the spraying is completed, it avoids the blind spots caused by the fixed angle, ensures that the coating thickness is uniform, and further increases the spraying area per unit time, thereby improving the spraying effect and production efficiency.

[0015] 2. By setting up a clamping mechanism, the prototype model is placed on a rectangular box. Then, the hydraulic cylinder is activated. The hydraulic cylinder pushes the front movable bracket to slide on two slide rods and move to the rear. At this time, the front movable bracket drives the corresponding two hinge rods to move through the two corresponding fixed blocks. The two front hinge rods drive the two fixed rods to rotate. The two fixed rods pull the two rear hinge rods to move. When the two rear hinge rods move, they drive the movable bracket to move through the two rear fixed blocks. At this time, the two movable brackets move closer to each other, and the two movable brackets drive the two fixed plates to slide in the slide groove and move closer to each other, thereby driving the two buffer pads to fix the prototype model and prevent position displacement. Then, several nozzles on the bracket spray the prototype model to avoid tilting or flipping due to uneven force, avoid rotational eccentricity caused by loose fixing, avoid damage to the model surface, and thus improve the uniformity of the prototype model spraying.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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.

[0026] Please see Figure 1-5As shown, this utility model is a spraying device for hand-made models, including a base 1, a rotating mechanism 2 and a clamping mechanism 3. The rotating mechanism 2 includes a rectangular cover 211 fixedly connected to the top of the base 1, a motor 212 fixedly connected to the bottom of the base 1, a support frame 111 fixedly connected to the outer wall of the base 1, a bracket 112 fixedly connected to the top of the support frame 111, and several spray nozzles 113 connected to the top of the bracket 112. A rotating shaft 213 passes through the central axis of the base 1 and is rotatably connected to the base 1. The top of the rotating shaft 213 passes through the rectangular cover 211 and extends outward. The output shaft of the motor 212 is fixedly connected to the rotating shaft 213 through a coupling. A circular plate 214 is fixedly connected to the outer wall of the rotating shaft 213, and the top of the circular plate 214 is fixedly connected to the rectangular box 311. By setting the rotating mechanism 2, the spraying blind area caused by the fixed angle is avoided, ensuring that the coating thickness is uniform and consistent, further increasing the spraying area per unit time, thereby improving the spraying effect and production efficiency.

[0027] The clamping mechanism 3 includes a rectangular box 311 mounted on top of the base 1. Fixed rods 312 are rotatably connected to the inner left and right walls of the rectangular box 311. Two hinge rods 313 are hinged to each of the two fixed rods 312. Two sliding rods 314 are fixedly connected inside the rectangular box 311. Two movable supports 315 are slidably connected to the outer walls of the two sliding rods 314. Fixed blocks 316 are fixedly connected to the left and right sides of each of the two movable supports 315. Several fixed blocks 316 are hinged to several hinge rods 313. A hydraulic cylinder 31 is fixedly connected to the inner front wall of the rectangular box 311. 7. The rear side of the hydraulic cylinder 317 is fixedly connected to the movable bracket 315 located on the front side. The top of the rectangular box 311 is provided with a sliding groove 318. Two fixed plates 319 are slidably connected to the inner wall of the sliding groove 318. The bottom of the two fixed plates 319 is fixedly connected to the top of the two movable brackets 315 respectively. Buffer pads 3110 are fixedly connected to the side of the two fixed plates 319 that are close to each other. By setting the clamping mechanism 3, the model is prevented from tilting or flipping due to uneven force. Rotational eccentricity caused by loose fixing can be avoided, and damage to the model surface can be avoided, thereby improving the uniformity of the hand model spraying.

[0028] A specific application of this embodiment is as follows: In use, the prototype model is placed on the rectangular box 311, and then the hydraulic cylinder 317 is activated. At this time, the hydraulic cylinder 317 pushes the movable support 315 located on the front side to slide on the two sliding rods 314 and move to the rear side. At this time, the movable support 315 located on the front side drives the corresponding two hinge rods 313 to move through the corresponding two fixed blocks 316. At this time, the two hinge rods 313 on the front side drive the two fixed rods 312 to rotate. At this time, the two fixed rods 312 pull the two hinge rods 313 on the rear side to move. When the two hinge rods 313 on the rear side move, the movable support 315 is driven to move through the two fixed blocks 316 on the rear side. At this time, the two movable supports 315 move closer to each other, and the two movable supports 315 drive the two fixed plates 319 to slide in the slide groove 318 and move closer to each other. This causes the two buffer pads 3110 to fix the prototype model, preventing positional displacement. Then, the prototype model is sprayed by several nozzles 113 on the bracket 112. Then, the motor 212 is started. At this time, the motor 212 drives the rotating shaft 213 to rotate at the central axis of the base 1 and the rectangular cover 211 through the coupling. When the rotating shaft 213 rotates, it drives the circular plate 214 to rotate. Through the fixed connection between the circular plate 214 and the rectangular box 311, it drives the rectangular box 311 to rotate. Under the action of the rectangular box 311 rotating, the prototype model is rotated, improving the uniformity of spraying. When the spraying is completed, the hydraulic cylinder 317 is started to retract. Through the reverse operation process, the two fixed plates 319 drive the two buffer pads 3110 away, releasing the fixation of the prototype model, and thus the prototype model can be removed.
