Description

Technical Field

[0001] This utility model belongs to the field of vehicle tooling technology, and specifically relates to an auxiliary welding tooling. Background Technology

[0002] Please refer to Figure 1 The automotive movable nut plate assembly generally consists of a reinforcing plate 1, a fixed plate 2, and a movable nut plate 3. When installing the automotive movable nut plate, the fixed plate 2 needs to be fixed on the reinforcing plate 1, and the movable nut plate 3 is placed under the reinforcing plate 1. The movable nut plate 3 has a certain amount of adjustment in both the X-axis (along the OX direction) and the Y-axis (along the OY direction). In this way, when installing the door, the matching requirements between the door and the other parts can be achieved by moving the mounting hole of the movable nut plate 3.

[0003] Currently, a protrusion 4 is usually added to the reinforcing plate 1, and a notch matching the protrusion 4 is set on the fixing plate 2 to position the fixing plate 2 for welding. However, the above welding method cannot guarantee the consistency of welding positioning, which can easily lead to the phenomenon of welding misalignment of the fixing plate 2, thereby reducing the positional accuracy of the movable nut plate 3 and the consistency of parts, and thus reducing the matching degree with the installation position.

[0004] Therefore, how to overcome the above-mentioned technical defects is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an auxiliary welding fixture that can not only effectively improve the positional accuracy of the movable nut plate and the consistency of the parts, but also improve the matching degree with the installation position.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An auxiliary welding fixture is used to install a movable nut plate assembly for vehicles. The movable nut plate assembly includes a reinforcing plate, a fixing plate, and a movable nut plate. The auxiliary welding fixture includes a limiting plate, which is provided with a positioning part for positioning with the reinforcing plate, a fixing part for fixing the fixing plate, and a limiting hole for limiting the movable nut plate.

[0008] Optionally, the positioning part is a positioning pin.

[0009] Optionally, the positioning part is a positioning protrusion.

[0010] Optionally, there are at least two positioning parts, and the at least two positioning parts are arranged opposite to each other.

[0011] Optionally, the positioning part is located near the edge of the limiting plate.

[0012] Optionally, the reinforcing plate has a rectangular structure, and the limiting plate is configured to conform to the shape of the reinforcing plate.

[0013] Optionally, the positioning part includes a first through hole, a second through hole, and a third through hole. The third through hole is disposed between the first through hole and the second through hole, and there are partitions between the first through hole and the third through hole, as well as between the second through hole and the third through hole, to press the fixing plate tightly onto the reinforcing plate.

[0014] Optionally, the limiting hole is provided along the length direction of the limiting plate, the fixing part is provided along the width direction of the limiting plate, and the third through hole intersects with and communicates with the limiting hole.

[0015] Optionally, the fixing part is a contour groove that conforms to the shape of the fixing plate, and the contour groove is disposed on one side of the limiting plate for contacting the fixing plate.

[0016] Optionally, the limiting hole is contoured to the movable nut plate, and the size of the limiting hole is larger than the size of the movable nut plate.

[0017] As can be seen from the above technical solution, when installing the automotive movable nut plate assembly, the positioning part needs to position the limiting plate on the reinforcing plate. At this time, the fixing part on the limiting plate corresponds to the position of the fixing plate on the automotive movable nut plate assembly, so that the fixing part presses the fixing plate tightly onto the reinforcing plate. At the same time, the limiting hole on the limiting plate corresponds to the position of the movable nut plate on the automotive movable nut plate assembly, so that the movable nut plate is placed in the limiting hole. This auxiliary welding fixture can fix the fixing plate on the reinforcing plate, allowing the movable nut plate to be adjusted to a certain extent along the X and Y axes within the limiting hole.

[0018] Compared with the existing protrusion positioning technology, the auxiliary welding fixture disclosed in this utility model embodiment has the following technical advantages:

[0019] 1) It can effectively improve the positional accuracy of the movable nut plate and the qualification rate of parts, improve the matching degree of the installation position, and reduce the cost of scrapped parts;

[0020] 2) The movable nut plate and the fixed plate are positioned using tooling profiles, which improves the consistency of the parts;

[0021] 3) The tooling is simple, which not only reduces the cost of manual operation, but also improves production efficiency. Attached Figure Description

[0031] In view of this, the core of this utility model is to provide an auxiliary welding fixture, which can not only effectively improve the positional accuracy of the movable nut plate and the consistency of the parts, but also improve the matching degree with the installation position.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Please refer to... Figures 2 to 4 .

[0033] Please refer to Figure 2and 3 The auxiliary welding fixture disclosed in this embodiment of the present invention is used to install a vehicle movable nut plate assembly. The vehicle movable nut plate assembly includes a reinforcing plate 100, a fixing plate 200 and a movable nut plate 300. The auxiliary welding fixture includes a limiting plate 400, wherein the limiting plate 400 is provided with a positioning part 401 for positioning with the reinforcing plate 100, a fixing part 402 for fixing the fixing plate 200, and a limiting hole 403 for limiting the movable nut plate 300.

[0034] When installing the automotive movable nut plate assembly, the positioning part 401 positions the limiting plate 400 onto the reinforcing plate 100. At this time, the fixing part 402 on the limiting plate 400 corresponds to the position of the fixing plate 200 on the automotive movable nut plate assembly, so that the fixing part 402 presses the fixing plate 200 tightly onto the reinforcing plate 100. Simultaneously, the limiting hole 403 on the limiting plate 400 corresponds to the position of the movable nut plate 300 on the automotive movable nut plate assembly, so that the movable nut plate 300 is placed within the limiting hole 403. This auxiliary welding fixture allows the fixing plate 200 to be fixed onto the reinforcing plate 100, and allows the movable nut plate 300 to be adjusted to a certain extent along the X and Y axes within the limiting hole 403.

[0035] Compared with the existing protrusion positioning technology, the auxiliary welding fixture disclosed in this utility model embodiment has the following technical advantages:

[0036] 1) It can effectively improve the positional accuracy and part qualification rate of the movable nut plate 300, improve the matching degree of the installation position, and reduce the cost of scrapped parts;

[0037] 2) The movable nut plate 300 and the fixed plate 200 are positioned by tooling profiles, which improves the consistency of the parts;

[0038] 3) The tooling is simple, which not only reduces the cost of manual operation, but also improves production efficiency.

[0039] It should be explained that in the coordinate system, OX represents the X-axis direction and OY represents the Y-axis direction.

[0040] This utility model embodiment does not limit the specific structure of the positioning part 401. Any structure that meets the usage requirements of this utility model is within the protection scope of this utility model.

[0041] As one embodiment, the positioning part 401 disclosed in this utility model embodiment is a positioning pin, wherein the positioning pin is disposed on the limiting plate 400. Correspondingly, when positioning is achieved by using the positioning pin, a positioning hole 101 that cooperates with the positioning pin needs to be opened on the reinforcing plate 100 of the vehicle movable nut plate assembly. With this arrangement, the positioning pin is inserted into the positioning hole 101, and the limiting plate 400 and the reinforcing plate 100 of the vehicle movable nut plate assembly can be positioned and connected.

[0042] As another embodiment, the positioning part 401 disclosed in this utility model embodiment is a positioning protrusion, wherein the positioning protrusion is disposed on the limiting plate 400. Correspondingly, when the positioning part 401 adopts a positioning protrusion, a positioning groove that cooperates with the positioning protrusion is opened on the reinforcing plate 100 of the vehicle movable nut plate assembly. With this arrangement, the positioning protrusion and the positioning groove are matched to achieve positioning connection between the limiting plate 400 and the reinforcing plate 100 of the vehicle movable nut plate assembly.

[0043] The positioning unit 401 can be one, two or more, and when two are set, at least two positioning units 401 are set opposite to each other.

This setting not only facilitates the positioning of the entire limiting plate 400, but also facilitates processing and manufacturing.

[0045] It should be noted that the reinforcing plate 100 disclosed in this embodiment of the present invention has a rectangular structure, and the limiting plate 400 is set in the same shape as the reinforcing plate 100, which facilitates the positioning of the entire limiting plate 400.

[0046] In a specific embodiment of this utility model, the reinforcing plate 100 is a rectangular structure with rounded corners on all four sides. The corresponding limiting plate 400 is also a rectangular structure with rounded corners on all four sides. With this arrangement, when the limiting plate 400 and the reinforcing plate 100 are aligned, the fixing plate 200 corresponds to the fixing part 402, and the limiting hole 403 corresponds to the movable nut plate 300, which can further improve the alignment accuracy.

[0047] It should be noted that the fixing plate 200 disclosed in this utility model embodiment consists of three parts: a first positioning plate, a second positioning plate, and a third positioning plate. The first positioning plate and the second positioning plate are in contact with the reinforcing plate 100, and the first positioning plate and the second positioning plate are respectively provided with welding points to weld the first positioning plate and the second positioning plate to the reinforcing plate 100. The third positioning plate is set higher than the first positioning plate and the second positioning plate so that there is a gap between the third positioning plate and the reinforcing plate 100. With this arrangement, the movable nut plate 300 can have an adjustment amount along the X-axis and Y-axis directions at the lower part of the third positioning plate.

[0048] As one specific embodiment of this utility model, please refer to Figure 2 and Figure 4 The positioning part 401 disclosed in this embodiment of the present invention includes a first through hole 4011, a second through hole 4022 and a third through hole 4023. The third through hole 4023 is disposed between the first through hole 4011 and the second through hole 4022. A partition plate 4024 is provided between the first through hole 4011 and the third through hole 4023, and between the second through hole 4022 and the third through hole 4023, so as to press the fixing plate 200 onto the reinforcing plate 100.

[0049] The limiting hole 403 is provided along the length direction of the limiting plate 400, the fixing part 402 is provided along the width direction of the limiting plate 400, and the third through hole 4023 intersects with and communicates with the limiting hole 403.

[0050] Please refer to the attached document for details. Figure 2 Understandably, in this embodiment of the present invention, the first through hole 4011 corresponds to the first positioning plate, the second through hole 4022 corresponds to the second positioning plate, and the third through hole 4023 corresponds to the third positioning plate. The fixing plate 200 is pressed onto the reinforcing plate 100 by the partition plate 4024.

[0051] In another specific embodiment of this utility model, the fixing part 402 disclosed in this embodiment is a contour groove that conforms to the shape of the fixing plate 200. The contour groove is disposed on one side of the limiting plate 400 for contacting the fixing plate 200.
