Description

Technical Field

[0001] The invention relates to the technical field of automobile painting tooling auxiliary tools, in particular to a directional flow guide device for electrophoretic liquid on an automobile engine cover. Background Art

[0002] In the coating production module, the car needs to go through pre-treatment and electrophoresis to protect the body metal layer from external acid rain, oxygen, water and other substances, to increase the corrosion resistance of the body, thereby ensuring the strength of the body to ensure the safety of passengers. Electrophoresis is to use the electric field force to deposit paint particles on the metal surface of the car body to form a uniform layer of primer. Compared with the traditional spraying method, the electrophoresis process has better anti-corrosion performance, so it is widely used in the primer coating of automotive parts, complete vehicles and various metal products.

[0003] Considering that the automobile body in white is made through processes such as multi-layer sheet metal overlap, edge pressing, and resistance spot welding, it is easy to form a closed cavity, which makes it difficult for the body to completely discharge the liquid in the closed cavity in a short time when passing through the coating tank. A part of the electrophoretic liquid will be retained in the body interlayer and the closed cavity. When the wet film electrophoretic body is dehydrated, cross-linked and cured in the drying room, the retained electrophoretic liquid may gather together and flow out in strands, resulting in electrophoretic flow marks on the exterior surface of the body. Since the topcoat in the subsequent process cannot completely cover the flow marks, the flow mark positions need to be polished and blown clean, which will generate a lot of dust and destroy the anti-corrosion performance of the electrophoretic coating, thereby affecting the visual appearance of the topcoat body. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a directional flow guide device for electrophoretic liquid on a car engine hood. By clamping a liquid receiving box on both sides of the engine hood and providing a first liquid discharge port on the liquid receiving box, the retained electrophoretic liquid flowing to the side of the engine hood can be received by the liquid receiving box and discharged to the hair compartment area through the first liquid discharge port, thereby effectively preventing the electrophoretic liquid from flowing onto the vehicle body to form flow marks, thereby ensuring the visual effect of the appearance of the topcoat vehicle body.

DETAILED DESCRIPTION

[0028] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0029] Embodiment 1

[0030] In a typical embodiment of the present invention, reference is made to Figure 1 As shown, a directional flow guide device for electrophoresis liquid on a car engine cover comprises a liquid receiving box 1. Two sets of clamping parts are arranged at the bottom of the liquid receiving box 1. The clamping parts are perpendicular to the length direction of the liquid receiving box 1 and extend to the side of the liquid receiving box close to the engine cover. The clamping parts are used to clamp with the waist-shaped holes at the bottom of the engine cover to fix the liquid receiving box 1 on the bottom surfaces of both sides of the engine cover 12. A first liquid discharge port 9 is arranged at the end of the liquid receiving box 1 close to the side of the engine cover 12. The first liquid discharge port 9 is arranged correspondingly in the internal hair compartment area of ​​the fuselage.

[0031] like Figure 1 As shown, the clamping part includes a first clamping part and a second clamping part. The first clamping part is vertically arranged at the bottom of the liquid receiving box 1 near the front end, and the second clamping part is vertically arranged at the middle position of the bottom of the liquid receiving box 1.

[0032] The first clamping part and the second clamping part are arranged at positions corresponding to the waist-shaped hole, such as Figure 3 As shown, waist-shaped holes 13 on the inner plate and waist-shaped holes 14 under the inner plate are provided at both sides of the bottom of the engine cover 12, the first clamping portion corresponds to the position of the waist-shaped holes 13 on the inner plate, and the second clamping portion corresponds to the position of the waist-shaped holes 14 under the inner plate.

[0033] like Figure 1 As shown, the first clamping portion includes a sleeve 3, a rotating shaft 4, a rotating handle 5, a claw 6, a spring 7 and a spring fixing rod 8.

[0034] One end of the sleeve 3 is fixed under the liquid receiving box 1, and the other end extends to the side of the liquid receiving box 1 close to the engine cover. One end of the rotating shaft 4 is connected to the rotating handle 5, and the other end passes through the sleeve 3 from the side of the liquid receiving box 1 away from the engine cover and is vertically connected to the bottom end of the claw 6. An arc-shaped spring fixing rod 8 is provided on the outer side of the end of the sleeve 3, and the spring fixing rod 8 is connected to the middle position of the claw by a spring 7.

[0035] The structure of the first clamping part is as follows: Figure 1 As shown, the handle 5 is an annular structure and is located outside the liquid receiving box 1. The shaft 4 extends to the inside of the liquid receiving box 1 away from the handle 5. The spring fixing rod 8 has a tendency to pull the claw 6 toward the spring fixing rod 8 through the spring 7. The handle 5 rotates the shaft 4 to stretch the spring 7. After the hook at the top of the claw is aligned with the waist-shaped hole 13 on the inner plate, the handle 5 is released to clamp the top of the claw 6 at the waist-shaped hole 13 on the inner plate.

[0036] like Figure 1 and Figure 2 As shown, the second clamping part includes a fixing rod 2, which is in a Z shape and is connected to the liquid receiving box 1 by two sections of horizontal rods and a vertical rod at one end. One end of one section of the horizontal rod is fixed below the liquid receiving box 1, and the other end extends to the inside of the liquid receiving box and is connected to the other section of the horizontal rod upward through the vertical rod. The clamping ear is provided on the inner horizontal rod and is clamped with the waist-shaped hole through the clamping ear.

[0037] like Figure 2 As shown, the bottom of the ear 21 is an equilateral triangle structure, which is connected by a group of bottom rods 214 and two groups of oblique rods 211. The top corner of the triangle structure is connected to the middle position of the connecting rod 212 parallel to the bottom of the triangle structure. There is a slot 213 between the bottom of the connecting rod 212 and the oblique rod 211. The slot 213 is used to be connected to the waist-shaped hole 14 under the inner plate. The bottom rod 214 is fixedly arranged parallel to the cross bar.

[0038] When installing the second clamping part, the liquid receiving box needs to be rotated 90° first, so that the clamping rod 212 passes through the inner plate lower waist-shaped hole 14 upward along the length direction of the inner plate lower waist-shaped hole 14, and then rotated 90° to achieve vertical clamping of the clamping rod 212 and the inner plate lower waist-shaped hole 14.

[0039] The structure of the first clamping part and the second clamping part after being installed is as follows Figure 3 As shown, the inner part of the liquid receiving box is located below the edge positions on both sides of the engine cover 12. The top of the liquid receiving box is open, and it is composed of a rectangular bottom plate and four side plates. There are drainage ports at its four corners, one of which is the first drainage port 9 at the rear end of the inner side of the liquid receiving box, and the other three groups are the second drainage ports 10.

[0040] like Figure 3As shown, during electrophoresis, the engine cover should be lifted to a set angle and fixed relative to the fuselage 11, so that the front end of the engine cover 12 is higher than the rear end, and the first drain port 9 is located at the rear end of the side of the engine cover 12, and the first drain port is located correspondingly in the hair compartment area. The purpose is to discharge the electrophoresis liquid to the hair compartment area through the first drain port 9 after it flows onto the liquid receiving box, so as to prevent the electrophoresis liquid from flowing to the outside of the fuselage 11 to form flow marks.

[0041] The other three groups of second liquid discharge ports 10 are provided to prevent the electrophoresis liquid from accumulating on the liquid receiving box during the electrophoresis process, so as to facilitate the timely discharge of the electrophoresis liquid.

[0042] The structural setting of the second clamping part mentioned above requires the liquid receiving box to be rotated 90° before the second clamping part can be installed. When the space in the factory is limited and the electrophoresis liquid directional flow guide device cannot be installed in this way, in a preferred example, the structure of the second clamping part can be set to be the same as that of the first clamping part. Both sets of clamping parts are clamped with the corresponding waist-shaped holes through claws. During the installation process, there is no need to rotate the liquid receiving box 1. This operation method requires little lateral installation space. However, it is necessary to ensure that the structures of the first clamping part and the second clamping part are set in a mirror image to achieve the opposite force of the waist-shaped hole on the two sets of claws, so that the liquid receiving box can be stably clamped on the engine cover 12.

[0043] In a preferred example, the second clamping portion also presents the above-mentioned triangular structure, but an adjustable structure of the triangular structure relative to the fixing rod 2 is added, so that the triangular structure is movably connected to the inner end of the fixing rod.

[0044] Specifically, Figure 4 As shown, the fixed rod 2 includes a first cross bar 22, a second cross bar 23 and a vertical bar 24. The second cross bar 23 is fixedly connected to the bottom of the liquid receiving box 1. The inner end of the second cross bar 23 is connected to the first cross bar 22 through the vertical bar 24 to form a Z-shaped structure.

[0045] The bottom of the ear 21 is also in a triangular structure, and a clamping rod 212 is provided at the top of the ear 21 for passing through the waist-shaped hole upward and clamping above the waist-shaped hole. The triangular structure is composed of a bottom rod 214 parallel to the first crossbar 22 and two groups of oblique rods 211 above the bottom rod 214. A clamping groove 213 is formed between the outer sides of the two oblique rods 211 and the clamping rod 212.

[0046] One end of the triangular structure is hinged to the end of the fixing rod 2 , and the other end is connected to the fixing rod 2 near the end through an elastic member, and the elastic member is hinged to the fixing rod 2 and the ear 21 .

[0047] Specifically, a hinge hole 221 is provided on the inner end of the bottom rod 214 near the first cross bar 22 and on the inner end of the first cross bar 22, and hinge connection is achieved through a pin shaft. A connecting ring 215 is provided on the side of the outer end of the bottom rod 214, and a connecting ring 222 is provided at the corresponding position of the first cross bar 22. The elastic member is a spring, and both ends are connected to the connecting ring through hooks.

[0048] When installing the second clamping part, pull the bottom rod 214 to stretch the spring so that the bottom rod 214 and the clamping rod 212 are both at 90 degrees with the first cross bar 22, pass the clamping rod 212 through the waist-shaped hole 14 under the inner plate, loosen the bottom plate 214, and under the action of the spring, make the clamping rod 212 perpendicular to the waist-shaped hole 14 under the inner plate, and complete the installation of the second clamping part. Figure 4 shown.

[0049] Furthermore, the inner end of the first cross bar 22 can be configured as a groove 223, and a through hole 224 is vertically arranged at the groove 223 to penetrate the first cross bar 22. The inner end side of the bottom bar 214 is configured as an ear plate, which is inserted into the groove and is hinged to the fixing bar 2 through a pin passing through the through hole 224. The outer end of the bottom plate 214 is also connected to the outer end of the first cross bar 22 through a spring, such as Figure 5 shown.

[0050] The second clamping portion of the present embodiment is additionally movably connected to the first cross bar 22 . When installing the electrophoresis liquid directional flow guide device, it is not necessary to make the liquid receiving box 1 perpendicular to the body 11 , thus saving installation space.

[0051] It is understandable that the corresponding structure of the electrophoretic liquid directional guide device should be treated with anti-corrosion, and the sharp corners should be blunted, and the welding spatter and burrs should be polished to prevent corrosion and scratches. The structure should have the set strength and rigidity to meet the use requirements. When installing, install the second clamping part first, and then install the first clamping part.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
