Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door tooling, in particular to a vehicle door tooling. Background Art

[0002] At present, the doors of conventional models are usually installed directly on the body through hinges, and the doors open in a fan shape with the hinges as the axis. Therefore, during the production process, the doors can pass through the painting production line together with the body as a whole. For example, the doors and the body undergo pre-treatment, electrophoresis, gluing, spraying, wax injection and other processes together, which is conducive to ensuring the consistency of the quality of the door products and the body products, and the overall production process is controllable.

[0003] With the rapid development of the automobile industry, B-pillar-less front and rear double sliding door models have gradually entered the market. Compared with traditional car doors, the doors of front and rear double sliding door models are sliding doors, and the B-pillar-less design means that the sliding doors have no support points and fixed points in the painting process. Therefore, for the painting process of the car doors, in the related technology, one solution is to make special tools or material racks for car doors to place the sliding doors separately. In the painting production, the sliding doors are produced separately and are not painted together with the car body. Another solution is to set up special sliding door tooling, fix the sliding door on the car body and spray it together with the car body, and change the opening mode of the sliding door to open by outward swing and close by inward swing. However, the former is prone to cause paint color difference between the sliding door and the car body, and the process quality is difficult to guarantee. The latter is prone to door rebound problems during the closing process of the sliding door, resulting in collision of the sliding door. Utility Model Content

[0039] The embodiments of the present invention are described in detail below, and 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] The vehicle door tooling 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0041] It should be noted that, at present, the doors of conventional car models are usually installed directly to the body through hinges, and the doors open in a fan shape with the hinges as the axis. Therefore, during the production process, the doors can pass through the painting production line together with the body as a whole. For example, the doors and the body go through pre-treatment, electrophoresis, gluing, spraying, wax injection and other processes together, which is conducive to ensuring the consistency of the quality of the door products and the body products, and the overall production process is controllable.

[0042] With the rapid development of the automobile industry, front and rear double sliding door models without B-pillars have gradually entered the market. Compared with traditional car doors, the doors of front and rear double sliding door models are sliding doors, and the design without B-pillars makes the sliding doors have no support points and fixing points. It is usually necessary to add side sliding tracks to fix the sliding doors. However, since the assembly parts of the side sliding tracks are rust-proof parts with a blackening process, they cannot be assembled before painting. The side sliding tracks need to be assembled during final assembly. Therefore, for the situation where the sliding doors have no support points and fixing points during the painting process, the existing technical solution is to make special door tools or material racks to place the sliding doors separately. During the painting production, the sliding doors are produced separately and are not painted together with the car body.

[0043] However, the above method is likely to cause paint color difference problems between the sliding door and the car body, and since the sliding door is produced and transported using special tools or racks, if the sliding door is not properly fixed, it is easy to cause bumps and scratches. In addition, the assembly of the sliding door involves an increase in the number of personnel at the special disassembly station. During the disassembly process, due to structural problems with the spray paint rack, it is easy to cause problems such as bumps on the paint film, making it difficult to ensure the corrosion resistance and appearance of the sliding door, and the process quality cannot be guaranteed. At the same time, the sliding door uses special tools or racks, which requires a certain amount of storage space and special personnel for transportation, which reduces production efficiency and increases production costs, and is not conducive to reducing costs and increasing efficiency.

[0044] Based on this, the present application proposes a vehicle door tooling 100, such as Figure 1-Figure 8 As shown, the vehicle door tooling 100 according to the embodiment of the utility model comprises: a mounting seat 1 , a double-link structure 2 , and a mounting frame 3 .

[0045] Among them, the mounting seat 1 is suitable for being fixedly connected to the body of the vehicle, the mounting frame 3 is suitable for being fixedly connected to the door of the vehicle, the double-link structure 2 is rotatably connected between the mounting seat 1 and the mounting frame 3, and the mounting frame 3 is suitable for driving the double-link structure 2 to rotate so that the door rotates to an open position or a closed position.

[0046] Specifically, a vehicle with front and rear double sliding doors is used as an example for explanation. It can be understood that the front and rear doors on one side of the vehicle with front and rear double sliding doors are both sliding doors. Therefore, a door tooling 100 is respectively provided for the front door and the rear door of the vehicle. Figure 1 and Figure 2 The door tooling 100 corresponding to the rear door is shown. Figure 3 and Figure 4 The door fixture 100 corresponding to the front door is shown. Specifically, the mounting seats 1 of the door fixture 100 corresponding to the front and rear doors are arranged at intervals and fixedly connected to the vehicle body. Further, taking the rear door as an example, the rear door is fixedly connected to the mounting frame 3 of the corresponding door fixture 100. Optionally, a positioning sleeve and a stud are provided on the mounting frame 3. The mounting frame 3 is positioned with the rear door through the positioning sleeve and is screwed with bolts, thereby improving the installation stability of the rear door. Furthermore, a double-link structure 2 is provided between the mounting frame 3 and the mounting seat 1 of the door fixture 100 corresponding to the rear door, and the double-link structure 2 can rotate relative to the mounting frame 3 and the mounting seat 1.

[0047] As a specific example, Figure 1 and Figure 2For example, after the rear door is fixedly connected to the mounting frame 3, the rear door is fixed to the vehicle body by the door tooling 100. During the painting process, for example, when the door is painted, it is necessary to use a painting robot to open the rear door. At this time, the painting robot applies an outward force to the rear door, and the force of the rear door is transmitted to the double-link structure 2 through the mounting frame 3 to drive the double-link structure 2 to rotate. The double-link structure 2 can provide two rotation units for the rear door by utilizing its own characteristics, so that the opening trajectory of the rear door can be changed to an outward swing opening, so that the rear door can be rotated to an open position, such as Figure 2 As shown, when the rear door is in the open position, the double-link structure 2 is swung outward and unfolded, and the mounting frame 3 is in the open position together with the rear door.

[0048] When the painting is completed and the door needs to be closed, the painting robot applies an inward force to the rear door to make it swing inward in the opposite direction to the closed position. Figure 1 As shown, when the rear door is in the closed position, the double-link structure 2 swings inward and contracts, and the mounting frame 3 is in the closed position together with the rear door. It can be understood that for sliding door vehicles, using the double-link structure 2 to achieve the rotation of the door is a prior art and will not be explained in detail in this application.

[0049] It should be noted that the door tooling 100 in the present application is installed on the vehicle body by the adjustment line in the welding workshop, the vehicle door is fixedly installed on the door tooling 100 and is transferred with the vehicle body to the electrophoretic slide after passing through the welding and painting connection conveying area to enter the painting workshop. After the full sequence of operations in the painting workshop is completed, the vehicle door passes through the transfer equipment with the vehicle body, and enters the final assembly workshop through the final assembly slide through the painting and final assembly connection conveying area. The door tooling 100 and the vehicle door are disassembled in the final assembly interior section, and the door is transferred to the door sub-assembly line for standby use. The door tooling 100 is transferred from the line-side logistics to the welding workshop for recycling.

[0050] With such arrangement, the vehicle door tooling 100 can fix the vehicle door on the vehicle body, thereby achieving stable installation of the vehicle door, having sufficient strength to withstand the impact of electrophoresis, and can realize opening or closing of the vehicle door by rotating the double-link structure 2. Like a conventional vehicle door, it can be opened freely, so that the vehicle door can be sprayed together with the vehicle body, which is beneficial to ensuring the consistency of process quality and does not require the use of special equipment or material racks, thereby helping to reduce costs and increase efficiency.

[0051] However, the above method is prone to door rebound problems during the door closing process. For example, when the door swings inward to close, the door is prone to rebound at the moment the door closes. If the robot is too close to the door, the door is prone to collide with the robot, causing damage to the door and robot failure.

[0052] Based on this, the vehicle door tooling 100 in the present application also includes an elastic member 4, which is fixed to the mounting seat 1. The elastic member 4 has a limiting portion 41, and the mounting frame 3 has a positioning portion 31 corresponding to the limiting portion 41. When the vehicle door is rotated to the open position, the limiting portion 41 is separated from the positioning portion 31. When the vehicle door is rotated to the closed position, the limiting portion 41 is suitable for abutting against the positioning portion 31 to limit the movement of the positioning portion 31. In other words, the elastic member 4 on the mounting seat 1 and the positioning portion 31 on the mounting frame 3 can be in a separated state or in an abutting limited state. Specifically, the rear door is continued to be used as an example for explanation. The elastic member 4 is fixed and does not move. When the rear door is opened, as shown in FIG. Figure 2 As shown, the mounting frame 3 rotates with the rear door. During this process, the limiting portion 41 of the elastic member 4 is separated from the positioning portion 31 of the mounting frame 3. The limiting portion 41 of the elastic member 4 does not limit the positioning portion 31 of the mounting frame 3. When the mounting frame 3 rotates to the closed position with the rear door, as shown in FIG. Figure 1 and Figure 6 As shown, the positioning portion 31 on the mounting frame 3 moves to the limiting portion 41 of the elastic member 4, and the limiting portion 41 of the elastic member 4 and the positioning portion 31 of the mounting frame 3 abut against each other to limit the mutual movement of the positioning portion 31 and the elastic member 4, thereby limiting the movement of the rear door to avoid rebound and collision when the rear door is closed.

[0053] It should be noted that the installation and working mode of the door tooling 100 corresponding to the front door can refer to the description of the rear door, which will not be repeated here.

[0054] According to the vehicle door tooling 100 of the embodiment of the utility model, the vehicle door tooling 100 can fix the vehicle door on the vehicle body, realize the stable installation of the vehicle door, and the vehicle door can be opened or closed by rotating the double-link structure 2, thereby, the vehicle door can be sprayed together with the vehicle body, which is conducive to ensuring the consistency of process quality. At the same time, an elastic member 4 is fixedly mounted on the mounting seat 1, and the elastic member 4 has a limiting portion 41. When the vehicle door is rotated to the closed position, the limiting portion 41 of the elastic member 4 and the positioning portion 31 of the mounting frame 3 can be abutted against each other for limiting, thereby limiting the mutual movement of the positioning portion 31 and the elastic member 4, and then limiting the movement of the vehicle door, avoiding rebound and collision caused by the moment the vehicle door is closed.

[0055] It should be noted that the vehicle door tooling 100 in this embodiment can be used not only for sliding door vehicles but also for other vehicle models. For example, it can be extended to the production of vehicles such as front and rear outward swing doors and scissor doors.

[0056] In some embodiments of the present invention, Figure 6As shown, the limiting portion 41 is a limiting groove, the positioning portion 31 is a positioning pin, and when the vehicle door is in the closed position, the inner surface of the limiting groove is suitable for engaging with the outer surface of the positioning pin to limit the movement of the positioning pin.

[0057] Specifically, Figure 6 As shown, the locating pin is fixedly mounted on the mounting frame 3. When the mounting frame 3 rotates to the closed position along with the vehicle door, the locating pin moves along with the mounting frame 3 into the limiting groove of the elastic member 4 so that the outer surface of the locating pin is engaged with the inner surface of the limiting groove, thereby limiting the relative movement of the locating pin and the limiting groove. That is, at the moment the vehicle door is closed, the relative stillness of the mounting frame 3 and the mounting seat 1 is ensured, thereby limiting the movement of the vehicle door and avoiding rebound and collision at the moment the vehicle door is closed.

[0058] It can be understood that the limit groove is provided with a guiding slope. When the car door is opened, the locating pin of the mounting frame 3 applies force to the elastic member 4, and the elastic member 4 is deformed under the action of the force. When the locating pin follows the movement of the mounting frame 3, it can move out of the limit groove under the guidance of the guiding slope, thereby realizing the separation of the locating pin and the limit groove. It should be noted that in the process that the locating pin follows the mounting frame 3 to move to the limit groove of the elastic member 4, the locating pin applies force to the elastic member 4, and the guiding slope can still play a certain guiding role to guide the locating pin into the limit groove. Such a setting facilitates the locating pin to move in or out of the limit groove, and avoids the car door being difficult to open due to excessive clamping.

[0059] In some embodiments of the present invention, the elastic member 4 is a torsion spring. Figure 6 As shown, the elastic member 4 is constructed as a torsion spring, one end of which is fixedly mounted on the mounting seat 1, and the other end is suspended and provided with a limit groove. When the mounting frame 3 rotates to the closed position following the vehicle door, the positioning pin moves with the mounting frame 3 to the limit groove of the elastic member 4. The limit groove can limit the movement of the positioning pin, and thus limit the movement of the vehicle door. It should be noted that the torsion spring itself has elastic force, so that it can play a certain buffering role for the closing of the vehicle door, which is beneficial to further avoid the rebound of the vehicle door.

[0060] In some embodiments of the present invention, Figure 5 and Figure 7 As shown, the double-link structure 2 includes: a first link 21 and a second link 22 , the first link 21 and the second link 22 are opposite and spaced apart, and the first link 21 and the second link 22 are both rotatably connected between the mounting seat 1 and the mounting frame 3 .

[0061] Specifically, Figure 7As shown, the double-link structure 2 includes a first link 21 and a second link 22, wherein the first link 21 and the second link 22 are arranged opposite to each other and spaced apart, wherein one end of the first link 21 is rotatably connected to the mounting seat 1, and the other end is rotatably connected to the mounting frame 3, and one end of the second link 22 is rotatably connected to the mounting seat 1, and the other end is rotatably connected to the mounting frame 3.

[0062] As a specific example, let's continue to use the rear door painting as an example. Figure 7 As shown, when the rear door needs to be opened, the painting robot applies an outward force to the mounting frame 3 through the rear door. Further, the applied force acts on the first connecting rod 21 and the second connecting rod 22 respectively through the mounting frame 3. The first connecting rod 21 and the second connecting rod 22 rotate in a direction away from the mounting seat 1 under the action of the external force. By utilizing the inherent characteristics of the double-link structure 2, the first connecting rod 21 and the second connecting rod 22 can provide two rotating units for the rear door, so that the opening trajectory of the rear door can be changed to an outward swing opening, so that the rear door rotates to an open position. When the rear door needs to be closed after painting is completed, the painting robot applies an inward force to the mounting frame 3 through the rear door, and the first connecting rod 21 and the second connecting rod 22 rotate in the direction close to the mounting seat 1 under the action of the external force, and finally, under the joint action of the first connecting rod 21 and the second connecting rod 22, the rear door is moved to the closed position. In this way, the opening or closing of the door is achieved by setting the first connecting rod 21 and the second connecting rod 22. The structure is simple and reliable, the cost is low, and various process requirements such as electrophoresis, gluing and painting in the door painting process are met.

[0063] In some embodiments of the present invention, Figure 7 As shown, the length of the first connecting rod 21 is smaller than the length of the second connecting rod 22 .

[0064] Specifically, when the first link 21 and the second link 22 rotate, if the lengths of the first link 21 and the second link 22 are different, the first link 21 and the second link 22 have different running trajectories and angular velocities. In the present application, if the length of the first link 21 is smaller than the length of the second link 22, under the joint action of the first link 21 and the second link 22, in the initial rotation trajectory of the door from a closed state to an outward swing, its translation distance in the width direction of the vehicle body is much greater than the translation distance in the length direction of the vehicle body. Therefore, it can be approximately regarded as the vehicle first translates along the width direction of the vehicle body to pull out the door frame, and then rotates and swings out to open it, thereby avoiding interference with the door frame during the opening process of the door. At the same time, the door tooling 100 does not need to make a large amount of translation in the length direction of the vehicle body, thereby reducing the truncation difference between the door and the door frame, which is beneficial to improving the appearance quality of the paint of the door and the side outer panel.

[0065] In some embodiments of the present invention, Figure 1 , Figure 7,and Figure 8 As shown, the double-link structure 2 also includes: a connecting shaft 23, both ends of the first connecting rod 21 and both ends of the second connecting rod 22 are rotatably connected to the mounting seat 1 and the mounting frame 3 through the connecting shaft 23, and the spacing distance between the two connecting shafts 23 on the mounting seat 1 is greater than the spacing distance between the two connecting shafts 23 on the mounting frame 3.

[0066] Specifically, both ends of the first connecting rod 21 and the second connecting rod 22 are rotatably connected to the mounting seat 1 and the mounting frame 3 through the connecting shaft 23, that is, the first connecting rod 21 is rotatably connected between the mounting seat 1 and the mounting frame 3 through the connecting shaft 23, and the second connecting rod 22 is rotatably connected between the mounting seat 1 and the mounting frame 3 through the connecting shaft 23, and the spacing distance between the two connecting shafts 23 on the mounting seat 1 is greater than the spacing distance between the two connecting shafts 23 on the mounting frame 3. In this way, the relative rotation of the first connecting rod 21, the second connecting rod 22, the mounting seat 1, and the mounting frame 3 is realized through the connecting shaft 23. At the same time, the spacing distance between the two connecting shafts 23 on the mounting seat 1 is set to be greater than the spacing distance between the two connecting shafts 23 on the mounting frame 3, which can further increase the translation distance difference of the door in the width direction and the length direction of the vehicle body, and further reduce the risk of interference with the door frame when the door is opened.

[0067] In some embodiments of the present invention, Figure 8 As shown, the connecting shaft 23 is a connecting shaft 23 bearing. Specifically, the double-link structure 2 requires four connecting shafts 23. In order to overcome the excessive resistance in the door switch, in some embodiments of the present application, the connecting shaft 23 is set as a connecting shaft 23 bearing. Such a setting is conducive to reducing the door opening and closing force, so that the opening and closing force is controlled within 30N, and the opening and closing resistance meets the robot operation requirements (less than 30N) and the tooling deformation (less than 3mm).

[0068] In some embodiments of the present invention, a limiting member is further included. The limiting member is disposed on the mounting frame 3 and is located on a side of the first connecting rod 21 away from the second connecting rod 22 .

[0069] Specifically, a limit member is also provided on the mounting frame 3. Optionally, the limit member can be set to a limit shaft, which is located on the side of the first connecting rod 21 away from the second connecting rod 22. In this way, during the opening process of the vehicle door, the first connecting rod 21 is abutted and limited by the limit member to limit the maximum opening angle (α) of the vehicle door, so that the vehicle door will not interfere with the vehicle body when it is at the maximum opening angle, and ensure that the overall width of the vehicle body along the width direction of the vehicle body is less than the spacing value of various equipment or robots on both sides of the painting production line when the vehicle door is open, so as to avoid collision between the vehicle door and various equipment or robots on both sides.

[0070] In some embodiments of the present invention, Figure 1-Figure 7As shown, the mounting base 1 has a first fixing member 11, the mounting frame 3 has a second fixing member 32, the two ends of the first connecting rod 21 are rotatably connected to the first fixing member 11 and the second fixing member 32, and the two ends of the second connecting rod 22 are rotatably connected to the first fixing member 11 and the second fixing member 32. Specifically, as Figure 1 As shown, the first fixing member 11 is fixedly installed on the mounting base 1, and the second fixing member 32 is fixedly installed on the mounting frame 3. The fixing and installation methods include but are not limited to welding, bolt connection, etc. One end of the first connecting rod 21 is rotatably connected to the first fixing member 11, and the other end is rotatably connected to the second fixing member 32. One end of the second connecting rod 22 is rotatably connected to the first fixing member 11, and the other end is rotatably connected to the second fixing member 32, thereby realizing the opening or closing of the vehicle door. The structure is simple and reliable, and the cost is low.

[0071] In some embodiments of the present invention, Fig. 9 and Fig.10 As shown, it also includes: a first magnetic component 5 and a second magnetic component 6. The first magnetic component 5 is fixed to the vehicle body, and the second magnetic component 6 is fixed to the outer surface of the vehicle door. The first magnetic component 5 is opposite to the second magnetic component 6 and is spaced apart.

[0072] Specifically, the door tooling 100 is also provided with a first magnetic component 5 and a second magnetic component 6. Optionally, the first magnetic component 5 can be a magnet, and the second magnetic component 6 can be iron or a magnet. When the first magnetic component 5 and the second magnetic component 6 are both magnets, the magnetism of the two is opposite. Further, the first magnetic component 5 is fixedly installed on the vehicle body. For the door tooling 100 corresponding to the front door, the first magnetic component 5 can be installed on the A-pillar of the vehicle body. For the door tooling 100 corresponding to the rear door, the first magnetic component 5 can be installed on the C-pillar of the vehicle body, and the second magnetic component 6 is directly installed on the outer surface of the door. The installation methods include but are not limited to bolt connections, and the second magnetic component 6 of the rear door is opposite to and spaced from the first magnetic component 5 on the C-pillar, and the second magnetic component 6 of the front door is opposite to and spaced from the first magnetic component 5 on the A-pillar. It can be understood that the second magnetic component 6 is located inside the door. With this arrangement, when the door is rotated to a closed position, the first magnetic component 5 and the second magnetic component 6 attract each other, thereby further preventing the door from opening. When the door needs to be opened, the second magnetic component 6 is attracted by the robot's magnetic structure to assist in opening the door, thereby solving the problem that the aluminum door cannot be opened by a magnetic robot.
