Description

Technical Field

[0001] This application relates to the field of assembly tooling technology, and in particular to an assembly tooling for a vehicle body side panel. Background Technology

[0002] The vehicle body side panel includes a side panel main body and multiple unit panels. The unit panels are welded to the side panel main body, and multiple mounting hole structures are formed on the unit panels for mounting other vehicle body components.

[0003] During the assembly of the vehicle body side panel, the unit panel is first fixed on the assembly fixture, then the side panel body is placed on the assembly fixture, ensuring that at least part of the side panel body and the unit panel are in contact. Then, the side panel body is moved to insert the unit panel into the side panel body. Finally, the side panel body and the unit panel are welded together using welding equipment.

[0004] However, during the process of inserting the unit panel into the side panel body, due to the gaps on the edge of the side panel body, it is easy for part of the unit panel to be inserted to the outside of the side panel body, resulting in the scrapping of the vehicle side panel. This affects production efficiency on the one hand and increases the production cost of the vehicle on the other. Utility Model Content

[0005] This application provides an assembly fixture for a vehicle body side panel to prevent incorrect insertion between the unit panel and the side panel body, thereby reducing the scrap rate of the vehicle body side panel.

[0006] To achieve the above objectives, the main technical solutions adopted in this application include: This application provides an assembly fixture for a vehicle side panel, used to assemble a unit panel and a side panel body. The assembly fixture includes a base, a unit panel clamping mechanism, a guide mechanism, and an anti-misalignment mechanism. The base extends along a first direction; the unit panel clamping mechanism is mounted on the base and extends along a second direction, which is perpendicular to the first direction, and includes a unit panel clamp; the guide mechanism is mounted on the base and extends along the second direction, and the side panel body is at least partially placed on the guide mechanism. Along the first direction, the side panel body has a degree of freedom of movement relative to the guide mechanism; the anti-misalignment mechanism is mounted on the unit panel clamping mechanism and at least partially abuts against the side panel body, applying a force away from the unit panel to the side panel body.

[0007] Furthermore, the anti-misconnection mechanism includes a mounting frame and a guide post. The guide post is mounted on the mounting frame and abuts against the side panel body to apply force to the side panel body through the guide post.

[0008] Furthermore, the anti-misconnection mechanism includes a spring that abuts against the guide post and the mounting bracket respectively. The guide post has the freedom of movement to move toward or away from the side panel body, so as to apply a force to the side panel body through the guide post.

[0009] Furthermore, the anti-misconnection mechanism also includes an adjusting block, in which an installation cavity is formed, a guide post is installed in the installation cavity, and the guide post extends at least partially outside the adjusting block.

[0010] Furthermore, the adjustment block is mounted on the mounting frame, and the adjustment block has the degree of freedom to be adjusted toward or away from the side panel body.

[0011] Furthermore, the guide post includes a main body and a guide ball, the guide ball being installed at the end of the main body facing the side body, and the guide ball having a rotational degree of freedom to rotate relative to the main body.

[0012] Furthermore, the guiding mechanism includes a movable guide and a movable limiting member. The side body is at least partially placed on the movable guide and has a degree of freedom of movement relative to the movable guide. A limiting space is formed within the movable limiting member, and the side body is at least partially located within the limiting space.

[0013] Furthermore, the movable limiting member includes a first limiting rod and a second limiting rod arranged along a first direction, and a limiting space is formed between the first limiting rod and the second limiting rod.

[0014] Furthermore, a first guide portion is formed at the end of the first limiting rod away from the base; a second guide portion is formed at the end of the second limiting rod away from the base, and the distance between the second guide portion and the first guide portion decreases from the side away from the base to the side of the base.

[0015] Furthermore, the assembly fixture also includes a side body clamping mechanism for clamping the side body, the side body clamping mechanism including a body fixture; a movable guide is installed on one side of the body fixture to guide the side body into the body fixture.

[0016] By applying a force away from the unit plate to the side panel body through the anti-misconnection mechanism, the side panel body undergoes a slight elastic deformation towards the outside of the vehicle side panel, thereby preventing the unit plate from being inserted into the groove, avoiding or significantly reducing the overlap error between the unit plate and the side panel body, and reducing the scrap rate of the vehicle side panel.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] like Figure 1As shown, the vehicle side panel 1 includes a unit panel 101 and a side panel body 102. Along the length direction of the side panel body 102, the side panel body 102 has an overlapping portion 1021 near the rear of the vehicle. The overlapping portion 1021 is bent relative to the side panel body 102. The edge of the unit panel 101 overlaps the inside of the side panel body 102 through the overlapping portion 1021. The overlapping portion is then welded by welding equipment, thereby assembling the unit panel 101 and the side panel body 102 to form the vehicle side panel 1.

[0028] When the unit panel 101 and the side body 102 are assembled by the assembly tool, the overlapping part 1021 is inclined relative to the side body 102, which drives the side body 102 to move along its length direction, so that the overlapping part 1021 can overlap with the side body 102.

[0029] Furthermore, since a groove 1011 is formed on the edge of the unit plate 101, during the movement of the side body 102, part of the unit plate 101 will move to the outside of the side body 102 through the groove 1011, causing the unit plate 101 and the side body 102 to overlap incorrectly.

[0030] It should be noted that in the above description, the inner side refers to the side of the vehicle that is close to the interior space after the vehicle is assembled, and the outer side refers to the side of the vehicle that is outside the vehicle after the vehicle is assembled.

[0031] like Figure 2 and Figure 3 As shown, as an implementation method, this application provides an assembly fixture for a vehicle side panel to solve the problem of overlapping misalignment during the installation of the vehicle side panel 1. The fixture is used to assemble the unit plate 101 and the side panel body 102 of the vehicle side panel 1, and to prevent overlapping errors from occurring during the assembly of the unit plate 101 and the side panel body 102.

[0032] The assembly fixture includes a base 2, a unit plate clamping mechanism 3, a guiding mechanism 4, and an anti-misalignment mechanism 5. The base 2 is used to install various components of the assembly fixture. The unit plate clamping mechanism 3 is used to clamp the unit plate 101. The guiding mechanism 4 is used to guide the movement of the side body 102. The anti-misalignment mechanism 5 is used to apply a force away from the unit plate 101 to the side body 102, thereby preventing the unit plate 101 from overlapping incorrectly with the side body 102.

[0033] It should be noted that this assembly fixture is used to assemble the vehicle body side panel 1 with two unit plates 101. Correspondingly, the assembly fixture includes two unit plate clamping mechanisms 3 and two anti-misalignment mechanisms 5. The two unit plate clamping mechanisms 3 respectively fix and clamp the two unit plates 101, and the two anti-misalignment mechanisms 5 respectively apply force to the overlapping parts 1021 at the corresponding positions of the two unit plates 101 to prevent overlapping errors from occurring at the two overlapping parts 1021.

[0034] Specifically, the base 2 extends along a first direction, which is parallel or substantially parallel to the length direction of the vehicle side panel 1, and the unit plate 101 and the side panel body 102 are both located on the same side of the base 2.

[0035] The unit board clamping mechanism 3 is installed on the base 2 and extends along a second direction, which is perpendicular to the first direction. The unit board clamping mechanism 3 includes a unit board clamp 301, which is used to clamp and fix the unit board 101.

[0036] The second direction is parallel or substantially parallel to the thickness direction of the vehicle body side panel 1.

[0037] It should be noted that the unit board clamp 301 includes at least two opposing grippers and a driving component that allows the grippers to move closer together or separate. The driving component moves the grippers, thereby clamping or releasing the unit board 101. Furthermore, the unit board clamp 301 can be any commercially available clamp with clamping function, and this application does not involve any improvement to the unit board clamp 301.

[0038] The guide mechanism 4 is installed on the base 2 and extends along the second direction. The side body 102 is at least partially placed on the guide mechanism 4. Along the first direction, the side body 102 has a degree of freedom of movement relative to the guide mechanism 4. By moving the side body 102 relative to the guide mechanism 4, the overlapping part 1021 of the side body 102 can be stably and accurately overlapped with the unit plate 101, thereby improving the assembly accuracy of the vehicle side body 1.

[0039] The anti-misconnection mechanism 5 is installed on the unit plate clamping mechanism 3 and extends toward the side body 102 so that at least a portion of the anti-misconnection mechanism 5 abuts against the side body 102.

[0040] The anti-misconnection mechanism 5 applies a force to the side panel body 102 to make it move away from the unit plate 101, causing the side panel body 102 to undergo slight elastic deformation towards the outside of the vehicle side panel, thereby preventing the unit plate 101 from being inserted into the groove 1011, avoiding or significantly reducing the overlap error between the unit plate 101 and the side panel body 102, and reducing the scrap rate of the vehicle side panel.

[0041] To more clearly illustrate the technical solution of this application, the following definitions are provided. Figure 2 The directions shown are front, rear, left, and right. The first direction is the length direction of the vehicle side panel 1, i.e., Figure 1 The left and right directions are defined as follows. The second direction is the thickness direction of the side panel 1 of the vehicle body, i.e. Figure 2 The front and back directions in the middle.

[0042] like Figure 4 , Figure 5and Figure 6 As shown, as one implementation, the anti-misconnection mechanism 5 includes a mounting frame 501 and a guide post 502. One end of the mounting frame 501 is fixed to the unit plate clamping mechanism 3, and the other end extends toward the side body 102. The guide post 502 is installed at the end of the mounting frame 501 near the side body 102, and the guide post 502 abuts against the side body 102. The guide post 502 applies force to the side body 102 to avoid or greatly reduce the misconnection of the unit plate 101 and the side body 102.

[0043] It should be noted that in this implementation, two anti-misconnection mechanisms 5 are installed on the base 2. In order to adapt to the installation shape at the unit board 101, the shape of the mounting bracket 501 of the two anti-misconnection mechanisms 5 is adaptively adjusted, and the structure of the guide column 502 is consistent.

[0044] like Figure 7 As shown, as one implementation method, the anti-misconnection mechanism 5 includes a spring 503, which abuts against the guide post 502 and the mounting bracket 501 respectively. The guide post 502 has the freedom of movement to move toward or away from the side body 102. The guide post 502 can be slidably installed on the mounting bracket 501, and the force of the spring 503 is transmitted to the side body 102 through the guide post 502.

[0045] Under the action of spring 503 or external force, guide post 502 can move relative to mounting bracket 501, so that guide post 502 flexibly abuts against side body 102, preventing side body 102 from plastic deformation due to the action of guide post 502 when side body 102 moves in the first direction, and preventing side body 102 from being scrapped.

[0046] Preferably, the guide post 502 is perpendicular to the side body 102 at its corresponding position, so that the force exerted by the guide post 502 on the side body 102 is perpendicular to the side body 102, thereby preventing the guide post 502 from affecting the movement of the side body 102 and the subsequent welding of the unit plate 101 and the side body 102.

[0047] As another implementation, the guide post 502 and the mounting bracket 501 are rigidly connected, that is, the guide post 502 and the mounting bracket 501 are relatively fixed, ensuring that the guide post 502 can apply the side body 102 force to the mounting bracket 501.

[0048] It should be noted that this application describes the guide post 502 as being movable relative to the mounting bracket 501.

[0049] like Figure 7As shown, as one implementation, the anti-misconnection mechanism 5 also includes an adjustment block 504, which is mounted on the mounting frame 501, and the guide post 502 is mounted on the mounting frame 501 through the adjustment block 504.

[0050] Specifically, an installation cavity 5041 is formed in the adjusting block 504, and the guide post 502 and the spring 503 are respectively installed in the installation cavity 5041. The guide post 502 has a degree of freedom of movement relative to the installation cavity 5041. At the same time, the guide post 502 extends at least partially outside the adjusting block 504 so that the guide post 502 abuts against the side body 102.

[0051] It should be noted that the guide post 502 has a stepped shaft structure, which ensures that the guide post 502 is at least partially located within the mounting cavity 5041, thereby improving the installation stability of the guide post 502.

[0052] As one implementation, a mounting through hole is formed in the mounting bracket 501, and the adjusting block 504 is installed in the mounting bracket 501 through the adjusting through hole, and the adjusting block 504 has the degree of freedom to be adjusted toward or away from the side body 102.

[0053] Specifically, an external thread is formed on the outer wall of the adjusting block 504. The adjusting block 504 is installed in the mounting through hole by the thread, so that the position of the adjusting block 504 can be adjusted by rotating the adjusting block 504, thereby adjusting the relative position of the guide post 502, and thus changing the force of the guide post 502 on the side body 102.

[0054] It should be noted that, apart from the different shapes of the mounting bracket 501 to accommodate the different mounting shapes of the unit boards 101, the structures of the other components (mounting bracket 501, guide post 502, spring 503, and adjusting block 504) of the two anti-misconnection mechanisms 5 provided in this application are the same.

[0055] like Figure 7 As shown, in one implementation, the guide post 502 includes a main body 5021 and a guide ball 5022. The guide ball 5022 is installed at the end of the main body 5021 facing the side body 102, and the guide ball 5022 has a rotational degree of freedom to rotate relative to the main body 5021. By setting the guide ball 5022, the friction between the guide post 502 and the side body 102 is reduced, thereby preventing the guide post 502 from affecting the quality of the inner end face of the side body 102.

[0056] like Figure 2 and Figure 3As shown, as one implementation method, the guide mechanism 4 includes a movable guide 401 and a movable limiting member 402. The movable guide 401 is used to guide the movement of the side body 102, and the movable limiting member 402 is used to limit the movement stroke of the side body 102 to ensure that the unit plate 101 can stably and accurately abut against the side body 102.

[0057] Specifically, the movable guide 401 extends along the second direction, and the side body 102 is at least partially placed on the movable guide 401, and the side body 102 has a degree of freedom of movement relative to the movable guide 401, so that the side body 102 can move under the guidance of the movable guide 401.

[0058] As one implementation, the movable guide 401 includes a guide rod that extends along a second direction and passes through the side body 102, thereby ensuring that the guide rod can provide stable guidance for the movement of the side body 102.

[0059] like Figure 3 As shown, as one implementation method, the assembly fixture also includes a main body clamping mechanism 6. The side body clamping mechanism 6 includes a main body clamp 601. After the unit plate 101 abuts against the side body 102, the main body clamp 601 clamps and fixes the side body 102, thereby facilitating the welding equipment to weld the unit plate 101 to the side body 102.

[0060] The guide rod is installed on one side of the main fixture 601. The guide rod guides the side body 102 into the main fixture 601, thereby improving the clamping accuracy of the main fixture 601 on the side body 102 and ensuring the welding accuracy of the vehicle body side panel 1.

[0061] It should be noted that, to ensure the clamping stability and accuracy of the side panel body 102, the assembly fixture includes multiple main body clamping mechanisms 6. Furthermore, it should be further explained that the main body clamp 601 includes at least two opposing grippers and a driving component that allows the grippers to move together or separate. The driving component moves the grippers, enabling the main body clamp 601 to clamp or release the side panel body 102. The main body clamp 601 can be any commercially available clamping fixture; this application does not involve any improvements to the main body clamp 601.

[0062] like Figure 2 and Figure 3 As shown, in one implementation, a limiting space 4021 is formed within the movable limiting member 402, and the side body 102 is at least partially located within the limiting space 4021. The limiting space 4021 extends along the first direction, thereby limiting the movement of the side body 102 along the first direction through the limiting space 4021.

[0063] like Figure 2 and Figure 3 As shown, specifically, the movable limiting member 402 includes a first limiting rod 4022 and a second limiting rod 4023. The arrangement of the first limiting rod 4022 and the second limiting rod 4023 along the first direction makes the first limiting rod 4022 and the second limiting rod 4023 have a certain distance along the first direction, thereby forming a limiting space 4021 between the first limiting rod 4022 and the second limiting rod 4023.

[0064] As an optional implementation, the side body 102 includes a B-pillar 1022, which is located within the limiting space 4021. The B-pillar 1022 cooperates with the movable limiting member 402 to limit the movement of the side body 102.

[0065] As one implementation, a first guide portion 40221 is formed at the end of the first limiting rod 4022 that is away from the base 2; a second guide portion 40231 is formed at the end of the second limiting rod 4023 that is away from the base 2. The distance between the second guide portion 40231 and the first guide portion 40221 decreases from the side away from the base 2 to the side of the base 2.

[0066] Specifically, along the second direction, the opening of the limiting space 4021 on the side opposite to the base 2 is a narrowed structure, which facilitates the installation of the B-pillar 1022 into the limiting space 4021.

[0067] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.

[0068] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended claims.
