[0027] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0028] Currently, when spraying the four doors of a vehicle, specific tooling is usually required to fix the relative position of the doors and the body to ensure the stability of the door position during the spraying process and avoid relative displacement between the door and the body during spraying, which may affect the spraying quality. However, the existing tooling has poor versatility and cannot accommodate a variety of vehicle models.

[0029] Reference below Figure 1-Figure 4 A spraying tool according to an embodiment of the present invention is described.

[0030] The spraying tool 1 according to the present invention includes: a base portion 11 and a support seat 12, the base portion 11 is provided with a first positioning portion 13 suitable for cooperating with the vehicle door inner panel in a first direction; the support seat 12 is arranged on one side of the base portion 11, and the support seat 12 is provided with a second positioning portion 14 suitable for cooperating with the side panel in a second direction; wherein the first direction and the second direction are orthogonal to each other, and the size of at least one of the first positioning portion 13 and the second positioning portion 14 is adjustable.

[0031] According to the present invention, the spraying tool 1 is provided with a base portion 11 and a support seat 12, and the base portion 11 is provided with a first positioning portion 13, and the first positioning portion 13 is suitable for cooperating with the inner panel of the vehicle door; the support seat 12 is provided on one side of the base portion 11, and the support seat 12 is provided with a second positioning portion 14, and the second positioning portion 14 is suitable for cooperating with the side panel of the vehicle body. When spraying the four doors of the vehicle body, the first positioning portion 13 and the second positioning portion 14 can be used to position the vehicle door and the vehicle body respectively, so that the vehicle door and the vehicle body remain relatively stable, ensuring that the vehicle door is fixed in the correct position, and improving the quality of topcoating and spraying.

[0032] Because at least one of the first positioning portion 13 and the second positioning portion 14 is adjustable in size, the spraying tool 1 can adapt to the differences in door and body structures of different vehicle models. The door inner panels and side panels of different vehicle models may vary in size, shape, etc. In this case, the spraying tool 1 can be adapted to different vehicle models by adjusting the sizes of the first positioning portion 13 and the second positioning portion 14. There is no need to design a set of spraying tools 1 specifically for each vehicle model. One set of spraying tools 1 can be used for door spraying operations of multiple vehicle models, greatly improving the versatility of the spraying tool 1 and reducing the number of spraying tools 1 required for specific vehicles. The increased versatility of the spraying tool 1 directly brings cost advantages. For example, during the project development phase, there is no need to invest a large amount of resources in the design and development of multiple special spraying tools 1, which can reduce the design and development costs of the spraying tool 1 and the number of spraying tools 1 required for a single project. A single project is expected to save 300 sets of spraying tools 1. At the same time, during subsequent use, due to the reduction in the number of spraying tools 1, maintenance costs are also reduced accordingly.

[0033] The first positioning portion 13 on the base portion 11 cooperates with the inner panel of the door in a first direction, and the second positioning portion 14 on the support seat 12 cooperates with the side panel in a second direction, and the first direction and the second direction are orthogonal to each other. The spraying work cooperates with the vehicle body and the door from two different directions, which can provide precise positioning for the door. During the spraying process, the stability of the door position is crucial to the spraying quality. Accurate positioning can ensure that the door maintains a fixed angle and position during spraying, avoiding problems such as uneven spraying and missing paint caused by shaking or position deviation of the door, thereby improving the consistency of the spraying quality of the four door surfaces. The adjustable size of the first positioning portion 13 and the second positioning portion 14 enables the spraying tool 1 to still achieve precise positioning of the door when facing changes in the door and body structure of different models. Even if the model changes, the spraying tool 1 can be coordinated with the body or door by adjusting the size of the corresponding positioning portion, which can ensure the stability of the door position and further ensure the stability and consistency of the spraying quality.

[0034] According to one embodiment of the present invention, a first positioning groove 130 open in a first direction is formed in the first positioning portion 13, and the first positioning groove 130 is suitable for clamping at least a portion of the edge of the inner panel of the vehicle door; the second positioning portion 14 is formed with a second positioning groove 140 open in a second direction, and the second positioning groove 140 is suitable for clamping at least a portion of the edge of the side panel.

[0035] The first positioning portion 13 is formed in a first positioning groove 130 open in the first direction, which can accurately clamp at least a portion of the edge of the vehicle door inner panel; the second positioning portion 14 is formed in a second positioning groove 140 open in the second direction, which can accurately clamp at least a portion of the edge of the side panel. The clamping positioning method makes the connection between the spraying tool 1 and the vehicle door inner panel and side panel tighter and more precise, and can accurately fix the vehicle door at a predetermined position and angle, providing a stable and reliable foundation for subsequent spraying operations, and effectively avoiding shaking, displacement, etc. of the vehicle door during the spraying process, thereby ensuring the accuracy of spraying and improving the consistency of the spraying quality of the four door surfaces.

[0036] Since the first direction and the second direction are orthogonal to each other, the first positioning groove 130 and the second positioning groove 140 can respectively position and support the vehicle door from two orthogonal directions. The multi-directional stable support structure can disperse the external force exerted on the vehicle door during the spraying process, further enhancing the stability of the vehicle door position. Even when affected by external factors such as spray gun pressure and airflow, the vehicle door can remain fixed, ensuring that the spraying effect is not affected.

[0037] Furthermore, the positioning slot design is tolerant of variations in the shape of door inner panels and side panel edges across different vehicle models. As long as the edge of the door inner panel or side panel fits within the positioning slot, the spray tool 1 can be used, eliminating the need for specialized designs tailored to the edge shape of each vehicle model. This increases the versatility of the spray tool 1, enabling it to meet the door painting needs of a wide variety of vehicle models, reducing the number of dedicated spray tool 1s required for each vehicle, and lowering the development and production costs of the spray tool 1.

[0038] According to one embodiment of the present invention, the base portion 11 extends in the second direction, and a first positioning portion 13 is provided at each end of the base portion 11. The base portion 11 extends in the second direction, and the first positioning portion 13 is provided at each end. This allows the inner door panel to be positioned at multiple points in the first direction via the two first positioning portions 13. Compared to single-point positioning, multi-point positioning can more evenly distribute external forces applied to the door during the spraying process, such as the impact force of the spray gun and the force of the airflow, effectively reducing shaking or displacement of the door caused by uneven force, thereby greatly improving the positional stability of the door during the spraying process and ensuring consistent spraying quality.

[0039] According to one embodiment of the present invention, the positioning portion includes: a first positioning plate 131, a second positioning plate 132 and a connecting plate 133, the first positioning plate 131 is connected to the base portion 11; the second positioning plate 132 is spaced apart from the first positioning plate 131; the connecting plate 133 is respectively connected to the first positioning plate 131 and the second positioning plate 132; wherein the first positioning plate 131, the second positioning plate 132 and the connecting plate 133 jointly define the first positioning groove 130.

[0040] The first positioning plate 131, the second positioning plate 132 and the connecting plate 133 jointly define the first positioning groove 130. This three-plate enclosed structure provides a stable and clear positioning space for the edge of the inner panel of the vehicle door. Compared with the simple single-plate positioning structure, the three-plate structure can constrain the edge of the inner panel of the vehicle door from both the inside and the outside, effectively preventing the vehicle door from shaking or displacing due to external forces (such as the impact force of the spray gun, the action of airflow, etc.) during the spraying process, thereby greatly improving the accuracy and stability of the vehicle door positioning, ensuring that the spraying operation can be carried out accurately and evenly, and improving the consistency of the spraying quality of the four door surfaces.

[0041] The first positioning groove 130 formed by the three plates has a clear opening direction and shape. When installing the spray tool 1, the operator can intuitively align the edge of the inner door panel and snap it into the first positioning groove 130. The operation is simple and convenient, which reduces the time for groping and adjustment during the installation process and improves the installation efficiency.

[0042] According to one embodiment of the present invention, the first positioning portion 13 also includes: a first positioning slot width adjustment member 134, the first positioning slot width adjustment member 134 is arranged on the first positioning plate 131 and / or the second positioning plate 132, and the first positioning slot width adjustment member 134 can be selectively moved in the width direction of the first positioning slot 130 to adjust the width of the first positioning slot 130.

[0043] The thickness of the door inner panels of different car models varies. The first positioning groove width adjustment member 134 can be selectively moved in the width direction of the first positioning groove 130, so as to flexibly adjust the width of the first positioning groove 130, so that the spray tool 1 can accurately adapt to the edges of door inner panels of various thicknesses, ensuring that the door inner panel can be tightly and accurately inserted into the first positioning groove 130, achieving precise positioning, and effectively avoiding the problem of inaccurate positioning caused by mismatched door thickness, thereby improving the consistency of the four-door surface coating spraying quality.

[0044] During the door manufacturing process, certain tolerances are inevitable. The first positioning slot width adjustment member 134 can be fine-tuned based on the actual thickness deviation of the door inner panel, compensating for the effects of manufacturing tolerances and ensuring that each door is stably positioned on the spray tool 1. This improves the spray tool 1's tolerance to door manufacturing errors and enhances positioning reliability.

[0045] Since the spraying tool 1 can adjust the width of the first positioning groove 130, the spraying tool 1 is no longer limited to vehicle models with doors of a specific thickness, and can be widely used in door spraying operations of various different vehicle models. There is no need to specially design and manufacture spraying tools 1 of different specifications for each vehicle model, which greatly improves the versatility of the spraying tool 1, reduces the number of special spraying tools 1 for special vehicles, and reduces the company's development and procurement costs of the spraying tool 1.

[0046] According to one embodiment of the present invention, the first positioning slot width adjustment member 134 is constructed as a hand-tightened stud, which is disposed on a side of the first positioning plate 131 facing away from the second positioning plate 132. The hand-tightened stud can be selectively rotated to move toward the second positioning plate 132. By constructing the first positioning slot width adjustment member 134 as a hand-tightened stud, the operator can easily adjust the width of the first positioning slot 130 by simply turning the stud by hand without the need for additional tools. This barehanded operation greatly simplifies the operating process and saves time in finding and using tools. When the spray tool 1 needs to be frequently adjusted for doors of varying thicknesses, adjustments can be completed quickly, significantly improving production efficiency and accelerating the overall pace of door spraying operations.

[0047] The threaded structure of the hand-tightened stud enables its rotation to have precise displacement control capabilities. The operator can slowly and finely rotate the stud according to the actual thickness of the door inner panel to achieve slight adjustments to the width of the first positioning groove 130, ensuring the best fit between the door inner panel and the first positioning groove 130, achieving precise positioning, and effectively avoiding inaccurate positioning caused by excessive or small adjustment range, thereby improving the consistency of the four-door surface coating spraying quality.

[0048] In addition, since the hand-tightening stud can be rotated continuously, the width of the first positioning groove 130 can be adjusted steplessly within a certain range, further enabling the spray tool 1 to flexibly adapt to various door inner panels of different thicknesses. Regardless of whether the thickness difference is small or large, the appropriate positioning width can be found by adjusting the hand-tightening stud, which greatly improves the versatility and adaptability of the spray tool 1 and reduces the need to replace the spray tool 1 due to mismatched door thickness.

[0049] Moreover, when the hand-tightened stud is rotated to the appropriate position so that the first positioning groove 130 reaches the required width, the threaded connection between the stud and the first positioning plate 131 can provide a reliable fixing effect, preventing the stud from loosening due to vibration or external force during the spraying process, and ensuring that the car door always maintains accurate positioning during the spraying process, avoiding affecting the spraying quality due to positioning changes.

[0050] According to one embodiment of the present invention, the support seat 12 is provided on the base portion 11 and is located between the two first positioning portions 13. The support seat 12 extends in a direction perpendicular to the plane of the base portion 11. The support seat 12 is provided on the base portion 11 and extends in a direction perpendicular to the plane of the base portion 11, thereby constructing a stable support frame for the entire spray tool 1. When performing the spraying operation, the support seat 12 can realize the connection between the vehicle door and the vehicle body, which can effectively prevent the vehicle door from shaking or deforming, and ensure that the spray tool 1 maintains structural stability and reliability during long-term use. The support seat 12 is located between the two first positioning portions 13, ensuring that the first positioning portion 13 and the second positioning portion 14 do not interfere with each other, and the operation is convenient.

[0051] According to one embodiment of the present invention, a support rod 121 extending from the support seat 12 is provided on the support seat 12, and at least a portion of the second positioning portion 14 is movably provided on the support rod 121 to adjust the size of the second positioning portion 14. At least a portion of the second positioning portion 14 is movably provided on the support rod 121, so that the size of the second positioning portion 14 can be flexibly adjusted according to the specific size of different vehicle doors. The doors of different models have differences in length, width and other dimensions. Through this adjustable structure, the spray tool 1 can accurately adapt to vehicle doors of various sizes, ensuring that the second positioning portion 14 can accurately position the key parts of the vehicle door, greatly improving the versatility of the spray tool 1 and its adaptability to doors of different models, and reducing positioning errors caused by mismatched door sizes.

[0052] The support rod 121 provides precise guidance for the movable adjustment of the second positioning part 14. The operator can make slight movements and adjustments to the second positioning part 14 on the support rod 121 according to actual needs to achieve fine positioning control, which helps to further improve the positioning accuracy of the vehicle door on the spraying tooling 1, so that the vehicle door maintains a stable and accurate position during the spraying process, thereby improving the spraying quality and avoiding quality problems such as uneven spraying and missing paint.

[0053] According to one embodiment of the present invention, the second positioning portion 14 includes: a fixed rod 141, a movable rod 142 and a movable stopper 143, the fixed rod 141 is arranged on the support rod 121 and extends in the second direction; the movable rod 142 is rotatably mounted on the support rod 121 and is spaced from the support rod 121 to define a second positioning groove 140; the movable stopper 143 is arranged on the side of the movable rod 142 away from the fixed rod 141, and the movable stopper 143 is suitable for limiting the movable rod 142 from moving along the support rod 121 in a direction away from the fixed rod 141.

[0054] Fixed rod 141 extends in the second direction, forming a clear directional positioning reference in conjunction with support rod 121. A movable rod 142 is rotatably mounted on support rod 121 and spaced apart from support rod 121 to define a second positioning slot 140, enabling the second positioning portion 14 to position the vehicle door. Furthermore, movable block 143 and movable rod 142 adjust the width of second positioning slot 140, allowing the spray tool 1 to adapt to the body side panels of different vehicle models, enhancing its versatility.

[0055] The method of positioning the spray tool 1 and the car body can be simply understood as follows: when positioning the spray tool 1 to the car body, you can first rotate the movable rod 142 to open the second positioning slot 140, so that the fixed rod 141 rests against the outside of the car body side panel, and then rotate the movable rod 142 in the opposite direction to rotate the movable rod 142 to the inside of the car body side panel. At this time, adjust the movable block 143 to reduce the width of the second positioning slot 140, so that the fixed rod 141 and the movable rod 142 are respectively abutted against the car body side panel to limit the position, and the assembly is completed.

[0056] Movable stopper 143 is located on the side of movable rod 142 facing away from fixed rod 141. Its function is to restrict the movement of movable rod 142 along support rod 121 in a direction away from fixed rod 141. During the door painting process, spray tool 1 is subject to various external forces, such as the impact of the spray gun and the reaction force of the airflow. Without the restraint of movable stopper 143, movable rod 142 may move under the influence of these external forces, resulting in inaccurate positioning. The presence of movable stopper 143 provides a reliable limit for movable rod 142, ensuring that movable rod 142 always remains in the correct position during the spraying process, thereby ensuring stable and reliable positioning.

[0057] The interaction between fixed rod 141, movable rod 142, and movable stop 143 forms a stable structural system. Fixed rod 141 is fixed to support rod 121, providing a solid foundation for the entire second positioning portion 14. The movable rod 142 interacts with the vehicle door through rotation and positioning slots, while being restrained by movable stop 143. The movable stop 143 further strengthens the stability of the movable rod 142. This stable structure can withstand various external forces during the vehicle door spraying process, preventing the second positioning portion 14 from loosening or deformation, and ensuring the long-term stable operation of the spraying tool 1.

[0058] According to one embodiment of the present invention, the support rod 121 is higher than the support seat 12 in the first direction, and at least a portion of the fixed rod 141 and / or the movable rod 142 overlaps the support seat 12. The support rod 121 is higher than the support seat 12 in the first direction, and at least a portion of the fixed rod 141 and / or the movable rod 142 overlaps the support seat 12, so that the pressure exerted by the vehicle door on the second positioning portion 14 can be more reasonably dispersed. When the vehicle door is placed on the spraying tool 1 for positioning, its weight and the external force generated during the spraying process will be transmitted to the support seat 12 through the fixed rod 141 and the movable rod 142. As an important supporting part of the base 11, the support seat 12 has a large bearing area and strong structural strength, which can effectively disperse these pressures and avoid local excessive force causing damage to the structure of the spraying tool 1, such as deformation of the support rod 121, breakage of the fixed rod 141 or the movable rod 142, thereby improving the structural stability and reliability of the entire spraying tool 1. Moreover, at least part of the fixed rod 141 and / or the movable rod 142 is overlapped on the support seat 12, which can prevent the fixed rod 141 and / or the movable rod 142 from detaching from the first direction (i.e., the height of the vehicle body) due to their own gravity when positioned and matched with the side panel of the vehicle body, thereby improving the stability of the spray tool 1 when positioning and matching.
