Description

Technical Field

[0001] The invention belongs to the technical field of automobile painting, and in particular relates to a painting topcoat auxiliary tool which utilizes a process hole of a vehicle body to achieve quick disassembly. Background Art

[0002] Painting is one of the four major processes in automobile production. During the painting process, the car is in a body-in-white state, and the four doors and the front and rear covers are only connected to the body by hinges, and other anti-collision and limit devices are not assembled. However, during the painting process, the car doors need to be opened and closed for operations such as painting and gluing the interior of the car body. Therefore, the car doors need to have the following states: the car doors need to be stably closed when the car body is transported; the car doors need to be opened and closed on demand.

[0003] Paint shops usually use auxiliary tools to achieve the above-mentioned state of car doors. Car door topcoat auxiliary tools are usually fixed with process nuts to ensure reliable installation of auxiliary tools. This method is not convenient to install and greatly affects the efficiency of painting production. In addition, paint residue is easily generated during installation and disassembly. When the paint residue falls on the car body, it will form paint film quality defects during the topcoat spraying process, increasing the time and cost of car body modification, which is also a prominent drawback of current paint shops. Summary of the invention

[0004] The purpose of the present invention is to provide a coating topcoat auxiliary tool that utilizes the vehicle body process hole to achieve quick disassembly, so as to solve the problem that the existing vehicle door topcoat auxiliary tool is prone to produce paint residues during installation and disassembly, causing paint film defects.

[0005] The objective of the present invention is achieved through the following technical solutions:

[0006] A coating topcoat auxiliary tool that uses a body process hole to achieve quick disassembly, comprising a locking handle 1, a connecting rod 2 fixedly connected to the locking handle 1, a locking positioning block 3 connected to a pin hole of the connecting rod 2, a locking column 4 fixedly connected to the connecting rod 2, a locking ring 5 fixedly connected to the locking column 4, and a magnetic ring 6 fixedly connected to the locking positioning block 3;

[0007] It also includes a left locking spring piece 7, a right locking spring piece 8, a structural rod 9, a structural connecting rod 21 and an inner door frame contact ball 22; the left locking spring piece 7 and the right locking spring piece 8 are respectively fixedly connected to the locking positioning block 3; the structural rod 9 is fixedly connected to the locking positioning block 3, the door frame limit block 11 is fixedly connected to the structural rod 9, the connecting cross bar 20 is fixedly connected to the door frame limit block 11, and the connecting cross bar 20 is fixedly connected to the structural rod 9, and the connecting cross bar 20 is also respectively connected to the connecting block 12, the door opening The limit block 19, the door closing limit block 18, and the outer door frame contact ball 16 are fixed; the rotating pin 17 is fixedly connected to the connecting block 12, the rotating pin 17 is connected to the pin hole of the rotating sleeve 15, the rotating sleeve 15 is fixedly connected to the door closing locking V-shaped rod 13, and the door closing locking V-shaped rod 13 is fixedly connected to the gravity cylinder 14; the structural connecting rod 21 is fixedly connected to the structural rod 9 and the connecting cross rod 20 respectively; the inner door frame contact ball 22 is fixedly connected to the door closing locking V-shaped rod 13.

[0008] Furthermore, an anti-slip sleeve is provided on the outer surface of the locking handle 1 .

[0009] Furthermore, the left locking spring piece 7 and the right locking spring piece 8 are symmetrical structures.

[0010] Furthermore, a positioning groove 10 is provided on the door frame limiting block 11 .

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention adopts an elastic locking structure, and the fixed installation of the auxiliary tool can be achieved by only pushing and pulling the locking handle. Compared with the traditional auxiliary tool, the installation method of this method is simpler and more convenient, which improves the production efficiency of the painting workshop and saves production labor costs;

[0013] The design takes into account that the outer door frame contact ball and the inner door frame contact ball are in contact with the outer side and inner side of the door frame of the vehicle body respectively. Compared with traditional auxiliary tools, the contact area between the spherical surface and the plane is smaller, thus avoiding the quality defect of paint residue contaminating the paint film due to the shaking and friction between the door frame and the auxiliary tool during the transfer of the vehicle body;

[0014] In addition, the design of the gravity cylinder makes the center of gravity of the door closing and locking V-shaped rod be on the right side when the door is closed, so that the door closing and locking V-shaped rod will encounter resistance when it rotates upward due to the bumps of the car body, effectively avoiding accidents of accidental opening of the door.

[0015] The door closing limit block has a bending structure, so that the horizontal axis of the door closing locking V-shaped rod and the axis of the connecting cross bar are at a certain angle. The design of this angle effectively avoids the accident problem of the door closing locking V-shaped rod rotating upward when the car door is subjected to external pulling force, causing the auxiliary device to detach.

At the same time, in the description of the present invention, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] like Figure 1 and Figure 2 As shown, the coating auxiliary tool of the present invention, which uses the process hole of the vehicle body to realize quick disassembly, is composed of a locking handle 1, a connecting rod 2, a locking positioning block 3, a locking column 4, a locking ring 5, a magnetic ring 6, a left locking spring 7, a right locking spring 8, a structural rod 9, a door frame stop block 11, a connecting block 12, a door closing locking V-shaped rod 13, a gravity cylinder 14, a rotating sleeve 15, an outer door frame contact ball 16, a rotating pin 17, a door closing limit stop block 18, a door opening limit stop block 19, a connecting cross bar 20, a structural connecting rod 21 and an inner door frame contact ball (22). The door frame stop block 11 is provided with a positioning groove 10.

[0027] Wherein, the locking handle 1 is fixedly connected to the connecting rod 2, an anti-slip sleeve is arranged on the outer surface of the locking handle 1, the connecting rod 2 is connected to the pin hole of the locking positioning block 3, the connecting rod 2 is fixedly connected to the locking column 4, and the locking column 4 is fixedly connected to the locking ring 5. The magnetic ring 6 is fixedly connected to the locking positioning block 3. The left locking spring piece 7 and the right locking spring piece 8 are symmetrical structures, which are fixedly connected to the locking positioning block 3 respectively. The structural rod 9 is fixedly connected to the locking positioning block 3, and the structural rod 9 is fixedly connected to the door frame limit block 11. The door frame limit block 11 is fixedly connected to the connecting cross bar 20, and the connecting cross bar 20 is fixedly connected to the structural rod 9. The connecting cross bar 20 is fixedly connected to the connecting block 12, the door opening limit block 19, the door closing limit block 18, and the outer door frame contact ball 16. The rotating pin 17 is fixedly connected to the connecting block 12. The rotating pin 17 is connected to the pin hole of the rotating sleeve 15, the rotating sleeve 15 is fixedly connected to the door closing and locking V-shaped rod 13, and the door closing and locking V-shaped rod 13 is fixedly connected to the gravity cylinder 14. The structural connecting rod 21 is fixedly connected to the structural rod 9 and the connecting cross rod 20 respectively. The inner door frame contact ball 22 is fixedly connected to the door closing and locking V-shaped rod 13.

[0028] Specifically, the above fixed connections are all welded.

[0029] Working process:

[0030] First, place it on the car door and embed the lower window frame of the car door into the positioning groove 10. Figure 3 Then, push the locking handle 1 outward so that the left locking spring piece 7 and the right locking spring piece 8 are in a contracted state as shown in FIG. Figure 3 As shown. At this time, the left locking spring sheet 7 and the right locking spring sheet 8 and other reverse hooks can be extended into the door process hole. Next, pull the locking handle 1 inward so that the left locking spring sheet 7 and the right locking spring sheet 8 are in the open state. At this time, the left locking spring sheet 7 and the right locking spring sheet 8 are clamped with the door process hole, so that the whole device is firmly fixed, as shown in FIG. Figure 4 shown.

[0031] When the door needs to be closed, the door is pushed so that the outer side of the door frame side folded edge contacts the outer door frame contact ball 16, and then the door is rotated to close and lock the V-shaped rod 13 so that the inner door frame contact ball 22 contacts the inner side of the door frame side folded edge. At this time, the door cannot be opened by pulling it. Figure 4 In this state, because the door closing limit stopper 18 has a bent structure, as shown in FIG. Figure 5 This makes the horizontal axis of the door closing and locking V-shaped rod 13 present a certain angle with the axis of the connecting cross bar 20, as shown in FIG. Figure 6 As shown, this angle design effectively avoids the accident problem of the auxiliary device being separated due to the upward rotation of the door closing and locking V-shaped rod 13 when the door is subjected to external pulling force. Specifically, the angle is 8 to 12 degrees. In addition, the design of the gravity cylinder 14 makes the center of gravity of the door closing and locking V-shaped rod 13 on the right side when the door is closed, so that the door closing and locking V-shaped rod 13 is resisted when it rotates upward due to the bump of the vehicle body.

[0032] When the door needs to be opened, it is only necessary to rotate the door to close and lock the V-shaped rod 13. Figure 5 In the status shown, the door can be opened as needed.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
