Description

Technical Field

[0001] The present invention belongs to the technical field of automotive painting tooling. Specifically, the present invention relates to a body topcoat painting tooling for SUV models and a method for using the same. Background Art

[0002] To meet the escalating market requirements for lightweight, low energy consumption, and environmental protection of automobiles, the steel plate selection design of automotive body products tends to be thinner. The positioning and installation plates of the tooling often adopt a design without reinforcement plates, which results in deformation of the thin steel plate after being stressed around the periphery.

[0003] The tooling for painting the front cover of the body topcoat of an SUV model is usually installed on the front cover lock installation hole. Since the front cover lock is made of a single-layer steel plate by one-time stamping, during the operation of employees after the tooling is installed, due to the too small contact surface between the tooling fastener and the body tooling hole, stress concentration will occur, resulting in deformation around the front cover lock, and the deformation amount cannot be controlled. Furthermore, it leads to the inability to install the lock body during final assembly, affecting the installation of the front cover lock during final assembly.

[0004] Therefore, during the body painting production process of SUV models, during the actual operation of operators, deformation around the front cover tooling after installation often occurs. Due to different operators, the sizes of the deformation amounts are also different, which places great demands on operators; and considering the constraints of production line speed and rhythm and other factors, simply considering from the aspect of operators has little effect.

Detailed implementation manners

[0024] The following is a more detailed description of the specific implementation manners of the present invention by describing the embodiments with reference to the accompanying drawings, aiming to help those skilled in the art have a more complete, accurate and in-depth understanding of the concept and technical solution of the present invention and facilitate its implementation.

[0025] It should be noted that in the following embodiments, the "first", "second" and "third" do not represent an absolute distinction relationship in terms of structure and / or function, nor do they represent the execution order, but are only for the convenience of description.

[0026] As Figures 1 to 3 shown, the present invention provides a painting tooling for the body topcoat of an SUV model, including a first support device for supporting a first body component, a positioning device provided on the first support device, and a second support device for supporting the first support device and creating a gap between the first body component and a second body component. The first support device has a first accommodating groove 6 for the first body component to be inserted into; the positioning device is configured to position and fix the first body component on the first support device and make the first body component fit with the inner wall surface in the first accommodating groove 6. The positioning device and the first support device are detachably connected, facilitating the disassembly and assembly between the first support device and the first body component.

[0027] Specifically, as Figure 1As shown in the figure, the first support device includes a positioning block 3 and a support rod 2 connected to the positioning block 3. A first receiving groove 6 is provided on the positioning block 3. The positioning device is used to fix the first vehicle body component on the positioning block 3. The first receiving groove 6 is a U-shaped groove, and openings are formed on the first outer wall surface, the second outer wall surface, and the third outer wall surface of the positioning block 3. The first outer wall surface and the second outer wall surface are the end faces at the opposite ends in the length direction of the positioning block 3, and the first outer wall surface and the second outer wall surface are planes perpendicular to the length direction of the positioning block 3. The third outer wall surface is the end face at one end in the width direction of the positioning block 3. The width direction of the positioning block 3 is perpendicular to the length direction of the positioning block 3, and the third outer wall surface is a plane perpendicular to the width direction of the positioning block 3. The third outer wall surface is located between the first outer wall surface and the second outer wall surface and is perpendicular to the first outer wall surface and the second outer wall surface. That is, the first receiving groove 6 is a groove recessed from the third outer wall surface of the positioning block 3 toward the inside of the positioning block 3 along the width direction of the positioning block 3, and the first receiving groove 6 is provided through along the length direction of the positioning block 3. The first receiving groove 6 forms a rectangular opening on the first outer wall surface, the second outer wall surface, and the third outer wall surface of the positioning block 3 respectively. The first vehicle body component is inserted into the first receiving groove 6 through these openings.

[0028] After the first vehicle body component is inserted into the first receiving groove 6, the first vehicle body component contacts the inner wall surface of the positioning block 3 located in the first receiving groove 6. This inner wall surface is a plane parallel to the length direction and the width direction of the positioning block 3. The rest of the first support device does not contact the first vehicle body component. Therefore, the contact area with the first vehicle body component is small. While providing support for the first vehicle body component, the contact area with the vehicle body component is reduced, making the first vehicle body component not easily deformed and improving the anti-deformation ability of the tooling fastening surface.

[0029] As Figure 1 shown in the figure, the first support device further includes a handle 1 connected to the support rod 2 and a reinforcing rod 5 provided on the positioning block 3. The support rod 2 has a certain length. The length direction of the support rod 2 is perpendicular to the length direction and the width direction of the positioning block 3. One end in the length direction of the support rod 2 is fixedly connected to the positioning block 3, and the handle 1 is fixedly connected to the other end in the length direction of the support rod 2. The handle 1 is a rectangular frame structure and is used for an operator to hold. The positioning block 3 has a second receiving groove 7 for the end of the support rod 2 to insert. The support rod 2 is inserted into the second receiving groove 7 and is fixedly connected to the positioning block 3. The support rod 2 extends outward toward the outside of the positioning block 3.

[0030] As Figure 1As described above, the first support device further includes a stop rod 4 and a reinforcing rod 5 disposed on the positioning block 3. The length direction of the stop rod 4 is parallel to the width direction of the positioning block 3, and the length direction of the reinforcing rod 5 is parallel to the length direction of the positioning block 3. The stop rod 4 and the reinforcing rod 5 are fixedly connected to the positioning block 3. The positioning block 3, the stop rod 4, and the reinforcing rod 5 are made of metal material. The arrangement of the stop rod 4 and the reinforcing rod 5 can improve the strength of the positioning block 3 and prevent the tooling from deforming during use.

[0031] As Figure 1 and Figure 2 shown, the positioning device includes a positioning pin 10. The positioning block 3 has a first positioning hole 13 for the positioning pin 10 to insert. The first positioning hole 13 communicates with the first receiving groove 6. The first vehicle body part has a second positioning hole for the positioning pin 10 to insert. The positioning pin 10 is a cylindrical pin. The first positioning hole 13 is a circular hole provided on the fourth outer wall surface of the positioning block 3. The fourth outer wall surface of the positioning block 3 is a plane perpendicular to the length direction and the width direction of the positioning block 3. Both the first positioning hole 13 and the second positioning hole are circular holes. The axis of the first positioning hole 13 is perpendicular to the length direction and the width direction of the positioning block 3. The first positioning hole 13 is located between the first outer wall surface and the second outer wall surface of the positioning block 3, and the first positioning hole 13 communicates with the first receiving groove 6, so that the positioning pin 10 can be inserted into the second positioning hole on the first vehicle body part located in the first receiving groove 6, realizing the positioning between the first vehicle body part and the first support device and ensuring the accurate connection position between the first support device and the first vehicle body part. The positioning pin 10 can also be withdrawn from the first positioning hole 13, so that the positioning device can be separated from the first support device.

[0032] As Figure 1 and Figure 2 shown, the positioning device further includes a locking bolt (not shown in the figure) that is threadedly connected to the positioning block 3 and is used to fix the first vehicle body part on the positioning block 3. The positioning block 3 is provided with an internal thread hole for the locking bolt to insert. The axis of the internal thread hole is parallel to the axis of the first positioning hole 13, and the internal thread hole communicates with the first receiving groove 6. After the first vehicle body part is embedded in the first receiving groove 6, align the first positioning hole 13 with the second positioning hole on the first vehicle body part, then insert the positioning pin 10 into the aligned first positioning hole 13 and the second positioning hole, and then tighten the locking bolt. The locking bolt applies pressure to the first vehicle body part, making the first vehicle body part fit with the inner wall surface in the first receiving groove 6, realizing the fixed connection between the first vehicle body part and the positioning block 3. Fixing the vehicle body in the form of the positioning pin 10 can achieve the best matching effect and fundamentally eliminate the phenomenon of deformation of the vehicle body front cover during spraying.

[0033] Preferably, a plurality of positioning pins 10 are provided. The number of the first positioning holes 13 and the second positioning holes is the same as that of the positioning pins 10. All the first positioning holes 13 are arranged in sequence along the length direction of the positioning block 3. During use, each positioning pin 10 is respectively inserted into an aligned first positioning hole 13 and second positioning hole, and cooperates with the locking bolts to ensure accurate positioning and reliable fixation of the first support device and the first vehicle body component.

[0034] As Figure 1 and Figure 2 shown, in this embodiment, two positioning pins 10 are provided in total.

[0035] As Figure 1 and Figure 2 shown, the positioning device further includes a connected first support rod 11 and a second support rod 12. The positioning pin 10 is arranged on the first support rod 11 and is fixedly connected to the first support rod 11. Both the first support rod 11 and the second support rod 12 have a certain length. The length direction of the first support rod 11 is perpendicular to the length direction of the second support rod 12. The length direction of the first support rod 11 is also perpendicular to the axis of the positioning pin 10. The axis of the positioning pin 10 is also perpendicular to the length direction of the second support rod 12 in space. The second support rod 12 is fixedly connected to the first support rod 11 at the middle position in the length direction of the first support rod 11, and the second support rod 12 is located at the middle position between the two positioning pins 10. After the positioning pin 10 is inserted into the first positioning hole 13, the first support rod 11 and the second support rod 12 are located outside the positioning block 3. The length direction of the first support rod 11 is parallel to the length direction of the positioning block 3, and the length direction of the second support rod 12 is parallel to the width direction of the positioning block 3. The length of the first support rod 11 is greater than the length of the positioning block 3, and the length of the second support rod 12 is greater than the width of the positioning block 3. The first support rod 11 and the second support rod 12 can be used to provide a supporting effect on the first vehicle body component, reduce the risk of deformation of the first vehicle body component, and are also used for the operator to hold by hand, facilitating the disassembly and assembly between the positioning device and the first support device.

[0036] As Figure 1 and Figure 3As shown in the figure, the second support device includes a bottom plate 8 and a support frame 9 disposed on the bottom plate 8 and used to support the first support device. The first support device has an avoidance hole for the support frame 9 to be inserted into. The bottom plate 8 is fixedly connected to the third body component of the vehicle body. The support frame 9 is fixedly connected to the bottom plate 8. The support frame 9 is horizontally arranged and extends outward from the bottom plate 8. The length direction of the support frame 9 is parallel to the length direction of the vehicle body. The avoidance hole is a through hole penetrating through the handle 1. During use, the support frame 9 is inserted into the avoidance hole of the handle 1, the handle 1 contacts the support frame 9, and the support rod 2 extends upward from the support frame 9. The second support device can provide a supporting effect on the first support device, so that the first support device can provide a supporting effect on the first body component.

[0037] The first body component is a component on the vehicle body that can rotate relative to the second body component and the third body component. The second body component and the third body component are relatively fixed to each other. The first body component is rotatably connected to the main body part of the vehicle body, and the rotation center line of the first body component is parallel to the width direction of the vehicle body. The second body component and the third body component are fixedly connected to the main body part of the vehicle body. The first body component can rotate up and down relative to the second body component. After the first body component rotates downward until it contacts the second body component, there is no gap between the first body component and the second body component. In this way, after the vehicle body topcoat is sprayed, problems such as paint sagging and collision are likely to occur. Therefore, through the cooperation of the first support device, the second support device and the positioning device, the first body component is opened upward by a certain angle, so that there is a gap between the first body component and the second body component, avoiding direct contact between the first body component and the second body component, and the first body component is fixed, which can solve the quality problems of paint sagging and collision and achieve a good anti-sagging effect.

[0038] In this embodiment, the first body component is the front hood or the rear trunk lid, the second body component is the vehicle body side wall, and the contact surface on the first body component that contacts the inner wall surface of the positioning block 3 is located inside the first body component.

[0039] The present invention also provides a method for using a vehicle body topcoat painting tooling for an SUV model, including the following steps:

[0040] S1. Connect the first support device to the first body component by the positioning device, and install the second support device on the vehicle body;

[0041] S2. Install the first support device on the second support device, and leave a gap between the first body component and the second body component;

[0042] S3. Spray the vehicle body.

[0043] In the above step S1, the bottom plate 8 is installed on the third vehicle body component, and the support frame 9 is located below the first vehicle body component.

[0044] In the above step S2, the support frame 9 is inserted into the avoidance hole of the handle 1, the handle 1 contacts the support frame 9, the support rod 2 extends upward toward the support frame 9, the second support device can provide a supporting effect on the first support device, so that the first support device can provide a supporting effect on the first vehicle body component, fixing the first vehicle body component. A gap is formed between the first vehicle body component and the second vehicle body component. The first vehicle body component is opened upward at a certain angle toward the second vehicle body component, and the first vehicle body component does not contact the second vehicle body component.

[0045] In the above step S3, the SUV body topcoat painting tooling enters the painting station together with the body, and then the body is sprayed. During the spraying process, there is always a gap between the first vehicle body component and the second vehicle body component.

[0046] The present invention has been described exemplarily above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
