[0071] Figure 1 One of the three-dimensional structural schematic diagrams of the spraying device with quick-change and positioning cover structure components provided by this utility model is illustrated.

Figure 1 and Figure 2 As shown, the spraying device for quick replacement and positioning of cover structure components includes a fixed turntable 100, a turntable base 200, and a turntable fixture 300. The fixed turntable 100 supports the turntable base 200 and the turntable fixture 300. The fixed turntable 100 is set in a pit in the ground. The turntable base 200 is set on the upper part of the fixed turntable 100 and is connected to the fixed turntable 100 by bolts. The turntable base 200 supports the turntable fixture 300. The turntable fixture 300 is set on the upper part of the turntable base 200 and is positioned and engaged with the turntable base 200. It is connected by a clamping component (not shown) and is used to fix the workpiece 400 to be sprayed.

[0072] The spraying device provided by this utility model, which allows for quick replacement and positioning of cover structure components, enables rapid installation and replacement of the turntable fixture 300 by positioning and engaging it with the turntable base 200 and connecting them through clamping components. This meets the assembly needs of turntable fixtures 300 with different structures, saves installation and adjustment time, improves the operating efficiency of the spraying device, and meets the mixed-line production needs of different cover structures.

[0073] In one embodiment of this utility model, the fixed turntable 100 is welded from square metal tubes and rotates with the bottom surface of the pit. Specifically, the fixed turntable 100 rotates with the bottom surface of the pit via a rotating shaft and bearings; of course, other components can also be used to achieve the rotational engagement. When the fixed turntable 100 rotates, it drives the workpiece 400 to be sprayed to rotate via the turntable base 200 and the turntable fixture 300, thereby enabling a single robot to perform omnidirectional spraying of the cover structure. The coverage area of ​​the fixed turntable 100 is larger than that of the turntable base 200 to ensure that the fixed turntable 100 can be adapted to turntable bases 200 of different sizes, thus improving the stability of the spraying device.

[0074] In one embodiment of this utility model, the turntable fixture 300 is provided with a positioning pin hole (not shown), and the turntable base 200 is provided with a positioning pin shaft 210.

Alternatively, the turntable base 200 is provided with a positioning pin hole, and the turntable fixture 300 is provided with a positioning pin shaft 210, with the positioning pin hole and the positioning pin shaft 210 providing a positioning engagement. Regardless of which of the above two assembly methods is adopted, the installation method of the turntable fixture 300 can be simplified, and the disassembly and installation time of the turntable fixture 300 can be shortened. During installation, simply place the turntable fixture 300 on the upper part of the turntable base 200 and insert the positioning pin shaft 210 into the positioning pin hole. During disassembly, simply open the clamping parts and use a forklift to lift the turntable fixture 300 upwards to separate the turntable fixture 300 from the turntable base 200.

[0075] In one embodiment of this utility model, the turntable base 200 is a hollow rectangular frame, welded from 50mm square tubing made of aluminum alloy. By using aluminum alloy for the turntable base 200, its weight is effectively reduced, facilitating its movement. Positioning pins 210 are located at both ends of the turntable base 200. Specifically, as shown... Figure 3 The turntable base 200 is provided with two positioning pins 210 at its left and right ends respectively. The two positioning pins 210 are arranged at intervals along the width direction of the turntable base 200. Of course, the number of positioning pins 210 is not limited to this. More positioning pins 210 can be provided at both ends of the turntable base 200 or at least one positioning pin 210 can be provided on each of the four sides of the turntable base 200. The specific method is determined according to actual needs.

[0076] Furthermore, the turntable base 200 is provided with multiple first handles 220. Specifically, the turntable base 200 has two first handles 220, one located at one end of the turntable base 200 and the other at the other end. Of course, the number of first handles 220 is not limited to two; two or more first handles 220 can be provided at each end of the turntable base 200. By providing first handles 220 on the turntable base 200, it is convenient for operators to move the turntable base 200.

[0077] In one embodiment of this utility model, a positioning pin hole is provided in the turntable fixture 300, and correspondingly, a positioning pin shaft 210 is provided in the turntable base 200. The positioning pin hole is a through hole, and a sealing cap 320 is provided at the upper end of the positioning pin hole. The sealing cap 320 can protect the positioning pin shaft 210 and the positioning pin hole, preventing the coating material from being applied to the assembly surfaces of the positioning pin shaft 210 and the positioning pin hole.

[0078] In one embodiment of this utility model, Figure 3 Example 2: A three-dimensional structural schematic diagram of the spraying device for quick-change and positioning of the cover structure provided by this utility model, as shown in the figure. Figure 3 As shown, the turntable fixture 300 includes a lower fixture 330, an upper fixture 340, and a workpiece fixing fixture 350. The lower fixture 330 is located on the upper part of the turntable base 200. The lower fixture 330 is a rectangular frame. Of course, the shape of the lower fixture 330 is not limited to this and can be determined according to actual needs. The lower fixture 330 is constructed by splicing 50 aluminum profiles, which effectively reduces the weight of the lower fixture 330 while meeting the structural strength requirements.

[0079] The locating pin hole is located in the lower fixture 330, and the lower fixture 330 is connected to the turntable base 200 via a clamping component. Specifically, Figure 4 A schematic diagram of the positioning pin 210 provided by this utility model is shown in the example. Figure 4 As shown, the turntable base 200 is provided with a cuboid fixing block 390, and a positioning pin 210 is vertically mounted on the fixing block 390. The upper end of the positioning pin 210 is provided with a pointed tip, which serves as a guide, allowing the positioning pin 210 to be easily inserted into the positioning pin hole. Both ends of the lower tooling 330 are provided with cuboid fixing blocks 390, and positioning pin holes are located in and pass through the fixing blocks 390 of the lower tooling 330. Clamping members are provided on both sides of the turntable base 200, and the lower tooling 330 is clamped to the turntable base 200 by the clamping members on both sides, thereby fixing the lower tooling 330 to the upper part of the turntable base 200.

[0080] The upper fixture 340 has a rectangular frame, although its shape is not limited to this and can be determined according to actual needs. The upper fixture 340 is constructed from 50mm aluminum profiles, effectively reducing its weight while meeting structural strength requirements. The area of ​​the upper fixture 340 is smaller than that of the lower fixture 330. The upper fixture 340 is positioned above the lower fixture 330 to maintain a certain distance between them, ensuring forklift access and facilitating the lifting and transfer of the turntable fixture 300.

[0081] A workpiece fixing fixture 350 is disposed on the upper part of the upper fixture 340, and is used to fix the workpiece 400 to be sprayed. The specific structural form of the workpiece fixing fixture 350 can be various, depending on the shape of the workpiece 400 to be sprayed. This utility model has two structural forms of the workpiece 400 to be sprayed: one with a complex curved surface A. Figure 2 The workpiece to be sprayed (400) and the workpiece to be sprayed with a complex curved surface B.

[0082] In one embodiment of this utility model, such as Figure 3 The workpiece fixing fixture 350 is connected to the upper fixture 340 by bolts. The workpiece fixing fixture 350 has a certain height so that the workpiece 400 to be sprayed reaches the predetermined height after being installed in place. This arrangement is ergonomic and facilitates operation by the workers.

[0083] Furthermore, two second handles 331 are provided at both ends of the lower tooling 330. The two second handles 331 are spaced apart at the same end of the lower tooling 330. The second handles 331 make it convenient for operators to lift the lower tooling 330, which facilitates on-site turnover operations.

[0084] In one embodiment of this utility model, the bottom of the turntable fixture 300 is provided with multiple rollers, specifically, as shown in the figure. Figure 3 As shown, rollers are positioned at the four corners of the lower fixture 330, with one roller at each corner. The rollers on the lower fixture 330 facilitate the movement of the turntable fixture 300, meeting the flexible transfer requirements of the on-site painting logistics system. By positioning the rollers at the four corners of the lower fixture 330, the stability of the turntable fixture 300 is effectively improved. Furthermore, the rollers can be either directional wheels or omnidirectional wheels.

[0085] In one embodiment of this utility model, such as Figure 3 As shown, a fixing ring 360 is provided on the upper part of the workpiece fixing fixture 350. The fixing ring 360 is connected to the workpiece fixing fixture 350 by bolts. The outer diameter of the fixing ring 360 gradually decreases from top to bottom, that is, the cross-section of the fixing ring 360 is triangular or trapezoidal. The workpiece 400 to be sprayed is fitted onto the fixing ring 360. Since the outer diameter of the fixing ring 360 gradually decreases from top to bottom, when the lower end of the workpiece 400 to be sprayed is fitted onto the fixing ring 360, the deeper the fixing ring 360 enters the workpiece 400 to be sprayed, the tighter the workpiece 400 is fitted, and the better the stability. Preferably, a marking line is provided on the fixing ring 360 or next to the fixing ring 360. The marking line can indicate the position of the workpiece 400 to be sprayed, preventing incorrect placement of the workpiece 400.

[0086] In one embodiment of this utility model, Figure 5 A three-dimensional structural diagram of a spraying device for quickly replacing and positioning cover structural components according to another embodiment of the present invention is shown, such as... Figure 5 As shown, the upper part of the workpiece fixing fixture 350 is an inclined surface, and multiple quick clamps 380 for fixing the workpiece 400 to be sprayed are provided on the upper part of the workpiece fixing fixture 350. Specifically, the workpiece fixing fixture 350 includes multiple support rods and a positioning ring 370. The positioning ring 370 is inclined, and the multiple support rods are spaced apart below the positioning ring 370. The lower ends of the support rods are bolted to the upper fixture 340, and the upper ends of the support rods are bolted to the positioning ring 370. Multiple quick clamps 380 are provided on the inner side of the positioning ring 370. The quick clamps 380 are used to clamp the workpiece 400 to be sprayed, and the multiple quick clamps 380 are arranged circumferentially. After the workpiece 400 to be sprayed is placed on the positioning ring 370, the quick clamps 380 are used to clamp the workpiece 400 to be sprayed, thereby fixing the workpiece 400 to be sprayed.

[0087] Since the workpiece 400 to be coated in this embodiment is a complex spatial curved surface and an asymmetrical structure, in order to meet the needs of automated robotic coating, it is necessary to ensure that the B-axis of the complex curved surface of the workpiece 400 rotates perpendicularly to the ground. Therefore, the positioning ring 370 needs to be tilted. In this embodiment, the angle between the plane where the positioning ring 370 is located and the horizontal plane is 15°. Of course, the size of the angle is not limited to this and is determined according to the shape of the workpiece 400 to be coated.

[0088] The spraying device provided by this utility model, which allows for quick replacement and positioning of cover structural components, adopts a modular, lightweight, mobile, quick positioning and clamping structure design. Compared with the traditional spraying device structure, it is more convenient to use and can better meet the spraying needs of products with large batches, different spraying specifications and different shapes.

[0089] The spraying device provided by this utility model, which can quickly replace and position the cover structure components, can meet the transformation needs of existing turntable equipment on site, meet the current turntable load requirement of 200KG, and can realize the transfer of equipment such as forklifts. It has a simple structure, light weight and beautiful appearance.

[0090] In one embodiment of this utility model, such as Figure 7As shown, the spraying device that allows for quick replacement and positioning of the cover structure also includes a turntable electrical control assembly. The turntable electrical control assembly includes a turntable motor 501, a turntable reducer 502, and a turntable motor housing 503. The turntable motor housing 503 is located on the upper part of the fixed turntable 100. The turntable motor 501 and the turntable reducer 502 are both located inside the turntable motor housing 503. The rotating shaft of the turntable motor 501 is connected to the input shaft of the turntable reducer 502. The housing of the turntable motor 501 is connected to the housing of the turntable reducer 502 by bolts. The housing of the turntable reducer 502 is connected to the turntable motor housing 503 by bolts. The output shaft of the turntable reducer 502 is connected to the turntable base 200. The turntable motor 501 is used to drive the turntable base 200 to rotate.

[0091] The spraying equipment provided by this utility model can achieve the dual-station operation by setting two-degree-of-freedom curved arm components at both ends of the cross-support spraying assembly, thereby further improving the system efficiency.

[0092] The spraying equipment provided by this utility model is controlled by a control system through a cross-support spraying assembly, a workpiece rotation support device, and two free-crank arm assemblies, achieving linkage. Spraying is completed by rotating the workpiece 400 to be sprayed. That is, the spray gun remains stationary while the workpiece 400 rotates one revolution to complete the spraying. Then the spray gun moves down one height and sprays the next revolution until the surface of the workpiece 400 is completely covered. The operation is simple and the work efficiency is high.

[0093] The spraying equipment provided by this utility model controls the angular velocity of the turntable by adjusting the radius of the workpiece 400 to be sprayed, so as to ensure that each part of the workpiece 400 to be sprayed has the same linear velocity during the spraying process, thus ensuring uniform spraying effect.

[0094] The spraying equipment provided by this utility model adjusts and controls the angle of the spray gun 907 through the crank arm assembly 900 to ensure that the spray gun 907 is perpendicular to the surface of the workpiece 400 to be sprayed during the spraying process, thereby ensuring a uniform spraying effect.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
