Description

Technical Field

[0001] This utility model relates to the technical field of automobile manufacturing, and in particular to a positioning tooling. Background Technology

[0002] In the automobile manufacturing process, the final assembly interior line is responsible for assembling the windshield on the vehicle body. During the assembly process, it is necessary to control the gap between the windshield and the body as consistently as possible.

[0003] However, due to the large size and heavy weight of the windshield, operators need to use auxiliary equipment during installation. Therefore, they can only judge the gap by sight or touch, which is highly dependent on the operator's experience and skills, and the consistency is relatively poor, making it impossible to meet the vehicle's gap requirements.

[0004] Currently, there are some tooling tools used to assist in the installation of windshields to control gaps, but most of these tooling tools have problems such as difficulty in loading and unloading, inaccurate positioning, and easy displacement. Utility Model Content

[0005] Therefore, it is necessary to provide a positioning fixture that is easy to install and remove, accurate in positioning, and not prone to displacement, in order to address the problems of difficulty in controlling the gap during the current windshield installation process and the difficulties in loading and unloading, inaccurate positioning, and easy displacement of the positioning fixture.

[0006] This application first provides a positioning fixture for installing a windshield glass in the window frame between two A-pillars of a car. The fixture includes at least two fixture blocks, each fixture block having a mounting part and a limiting part that are fixed to each other. The mounting part is embedded with a magnet to detachably attach the fixture block to the front of the A-pillar. In the attached state, the limiting part is located inside the window frame.

[0007] In one embodiment, the mounting surface of the mounting part is designed to mimic the front profile of the A-pillar.

[0008] This design ensures that the mounting part can and can only be completely fitted to a specific position on the front of the A-pillar, thereby improving positioning accuracy and avoiding inconsistent gap widths caused by unstable installation of the tooling block.

[0009] In one embodiment, the mounting surface has a magnet hole, and the magnet is embedded in the magnet hole.

[0010] In one embodiment, the magnet is flush with the mounting surface.

[0011] This design allows the magnet to adhere to and adhere to the front of the A-pillar, thereby improving the adhesion reliability of the tooling block 100.

[0012] In one embodiment, the mounting surface has at least two rows of magnet holes arranged in parallel, each row of magnet holes including a plurality of magnet holes arranged at equal intervals.

[0013] In one embodiment, a protective component is fixedly attached to the mounting surface, the protective component completely covering the mounting surface and conforming to the shape of the A-pillar.

[0014] This design allows the protective components to provide some protection, preventing the tooling block from colliding with the A-pillar and causing wear.

[0015] In one embodiment, the protective element is a felt cloth, which is bonded and fixed to the mounting surface.

[0016] In one embodiment, the positioning fixture includes four fixture blocks, with each A-pillar corresponding to two fixture blocks, and the mounting surface of each fixture block is designed to mimic different positions on the front of the A-pillar.

[0017] In one embodiment, the cross-sectional area of ​​the limiting portion gradually decreases in the direction away from the front of the A-pillar.

[0018] This design allows the limiting part to act as a guide, facilitating both the installation of the windshield and the removal of the tooling blocks later.

[0019] In one embodiment, the mounting part has grip grooves on both sides along the length of the A-pillar to facilitate gripping by the operator.

[0020] The aforementioned positioning fixture consists of at least one fixture block installed on each of the two A-pillars. The limiting part of the fixture block can extend into the window frame and engage with the windshield and the edge of the window frame during the installation of the windshield by the operator to provide positioning and ensure that the gap between the windshield and the two A-pillars is relatively uniform. In addition, by embedding magnets in the mounting part, the fixture block can be attracted to a specific position on the A-pillar, thereby effectively improving the installation accuracy of the fixture block and reducing the difficulty of its installation and removal.

[0030] For ease of description, in this application, the direction of column A outward along the plane where the vertical window frame is located is defined as the front of column A.

[0031] Please combine Figure 1 as well as Figure 2 As shown, this application first provides a positioning fixture for installing a windshield glass in the window frame between two A-pillars of a car. It includes at least two fixture blocks 100. Each fixture block 100 includes a mounting part 10 and a limiting part 20 that are fixed to each other. A magnet (not shown) is embedded in the mounting part 10 to detachably attach the fixture block 100 to the front of the A-pillar. In the attached state, the limiting part 20 is located inside the window frame.

[0032] In this application, at least one tooling block 100 is installed on each of the two A-pillars. The limiting part 20 of the tooling block 100 can extend into the window frame and engage between the windshield and the edge of the window frame during the installation of the windshield by the operator to play a positioning role and ensure that the gap between the windshield and the two A-pillars is relatively uniform. In addition, by embedding a magnet in the mounting part 10, the tooling block 100 can be attracted to a specific position on the A-pillar, thereby effectively improving the installation accuracy of the tooling block 100 and reducing its installation and removal difficulty.

[0033] Please combine Figure 1 as well as Figure 2As shown, in some embodiments, the mounting surface 11 of the mounting part 10 is designed to mimic the front of the A-pillar, so that the mounting part 10 can and can only be completely fitted to a specific position on the front of the A-pillar, thereby improving the positioning accuracy and avoiding the occurrence of inconsistent gap widths due to unstable installation of the tooling block 100.

[0034] Specifically, when installing the windshield on the interior line of the final assembly workshop, the operator first places each tool block 100 in the corresponding sheet metal position on the front A-pillar of the vehicle body (the specific placement method is: before installing the windshield, the operator places the tool block 100 with magnets in the corresponding position on the A-pillar sheet metal according to the contour, so that the mounting surface 11 with magnets is in contact with the sheet metal), ensuring that the mounting surface 11 is in complete contact with the sheet metal. Then, the auxiliary equipment is used to install the windshield according to the process requirements. After the installation is completed, the tool block 100 is removed, and so on.

[0035] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the mounting surface 11 has a magnet hole 12, and the magnet is embedded in the magnet hole 12.

[0036] Preferably, in some embodiments, the magnet is flush with the mounting surface 11 so that the magnet can adhere to and be attracted to the front of the A-pillar, thereby improving the adhesion reliability of the tooling block 100.

[0037] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the mounting surface 11 has at least two rows of magnet holes 12 arranged in parallel, and each row of magnet holes 12 includes a plurality of magnet holes 12 arranged at equal intervals.

[0038] Of course, in some other embodiments, the number and distribution of the magnet holes 12 can also be adjusted according to the actual volume and weight of the tooling block 100, as long as it is ensured that the tooling block 100 can be firmly attached to the A column.

[0039] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, a protective component (not shown) is attached to the mounting surface 11. The protective component completely covers the mounting surface 11 and conforms to the shape of the A-pillar. The protective component can play a certain protective role and prevent the tooling block 100 from colliding with the A-pillar and causing wear.

[0040] Preferably, the mounting part 10 and the limiting part 20 are made of nylon and are machined; the protective part is made of felt cloth, which is bonded and fixed to the mounting surface 11.

[0041] More preferably, the tooling block 100 has a maximum length of 79mm, a maximum width of 69mm, and a maximum height of 32mm, and is machined; the protective cloth has a maximum length of 86mm, a maximum width of 106mm, and a maximum height of 0.5mm; the area of ​​the protective cloth is larger than the surface size of the mounting surface 11 to ensure that the protective cloth can cover the edge of the mounting surface 11.

[0042] The magnets are cylindrical with a thickness of 4.5mm and are fixed in the corresponding magnet holes 12 by adhesive bonding and interference fit.

[0043] In some embodiments, the positioning fixture includes four fixture blocks 100, with two fixture blocks 100 corresponding to each A-pillar, and each mounting surface 11 is designed to mimic the different positions of the front of the A-pillar.

[0044] Preferably, in some embodiments, the upper and lower ends of each A-pillar correspond to a tooling block 100, and the upper and lower ends of the two A-pillars are in the same position, so that the left and right sets of tooling blocks 100 can be interchanged and used interchangeably, and the versatility is relatively strong.

[0045] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the cross-sectional area of ​​the limiting part 20 gradually decreases in the direction away from the front of the A-pillar, so that the limiting part 20 can play a certain guiding role, which facilitates the installation of the windshield glass on the one hand, and also facilitates the removal of the tooling block 100 later.

[0046] Preferably, in some embodiments, the cross-section of the limiting portion 20 is triangular.

[0047] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the mounting part 10 has grip grooves 13 on both sides along the length of the A-pillar to facilitate gripping by the operator.

[0048] Preferably, in some embodiments, the edge of the grip groove 13 is chamfered to prevent scratches to the operator during gripping.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
