[0002] When assembling a frame, it is usually supported and positioned by a tooling. The accuracy of the tooling itself will affect the positioning accuracy and efficiency of the frame assembly, so the tooling itself needs to ensure the stability and accuracy of the structure during assembly. At present, most of the tooling of the frame is positioned and clamped by positioning parts + steel support + clamps during assembly. Although this method solves the positioning and clamping problems during tooling assembly, each positioning point needs to be carefully measured before positioning and welding. Once a dimension is measured incorrectly, the entire tooling may be reworked. Therefore, the accuracy of the tooling depends entirely on the level of the welding technician, which is very demanding, and the production efficiency is relatively low. Utility Model Content

DETAILED DESCRIPTION

[0020] like Figure 1-Figure 4As shown, the utility model provides a frame tooling assembly structure, including a bottom plate 1 and a plurality of positioning members, wherein the plurality of positioning members are used to position and support different parts of a frame 3. The plurality of positioning members are all arranged on the bottom plate 1 and the bottoms thereof are plugged and matched with the bottom plate 1 to realize the positioning of the position on the bottom plate 1. Among the plurality of positioning members, adjacent positioning members that are at an angle to each other are plugged and matched in the horizontal and / or vertical directions, that is, adjacent and non-parallel positioning members can be mutually interspersed in the horizontal and / or vertical directions for plugging and matching, thereby increasing the support strength and structural stability between the positioning members. Among them, plug-in fit specifically refers to a structural form of interlacing and splicing through grooves or holes, for example, a tenon is set at the bottom of the positioning piece, and a hole is set on the bottom plate. The interlacing of the tenon and the hole realizes the plug-in fit between the positioning piece and the bottom plate. Tenons are set on one side of some positioning pieces, and holes are set on other positioning pieces. The interlacing of the tenons and the holes realizes the plug-in fit between the positioning pieces; or, grooves are set on the bottom plate, and the bottom of the positioning piece is directly inserted into the groove at the corresponding position to realize the plug-in fit between the positioning piece and the bottom plate. Slots are set on some positioning pieces, and other positioning pieces are directly inserted into the corresponding grooves to realize the plug-in fit between the positioning pieces. The aforementioned structures such as tenons, holes, and grooves, as well as the shapes of the positioning pieces, are pre-formed by laser cutting using corresponding equipment.

[0021] The frame tooling assembly structure provided by the utility model is based on the above-mentioned setting. When assembling the frame tooling, the positioning piece and the bottom plate 1 and the adjacent positioning pieces at an angle to each other are interlaced, and the assembly accuracy of the frame tooling can be converted from manual control to mechanical equipment, simplifying the operation content of the assembly link, avoiding the dependence of the traditional assembly method on the skills of the welding technician and the difficulty of manual control accuracy operation, and can achieve good error prevention based on the mutual cooperation of the plug-in structure, reduce the skill requirements for the welding technician, and reduce the cost. Since the positioning and mutual cooperation are achieved through the plug-in structure, the welding process only needs spot welding and local forging welding, and no full welding is required, which can reduce the welding deformation of the frame tooling and improve the assembly accuracy of the frame tooling, thereby improving the assembly accuracy of the frame 3 when the frame tooling is used in the later stage, and can reduce the welding time and shorten the manufacturing cycle. Not only does it achieve the position accuracy of each positioning piece on the frame tooling when assembling, but it also increases the structural stability between the positioning pieces, reduces the deformation degree of the frame tooling under long-term use, and ensures the accuracy of the frame tooling under long-term use.

[0022] According to the different shapes and structures of the components at different positions of the frame 3, corresponding positioning structures can be provided on the positioning member to achieve positioning. For example, a positioning groove 26 is provided on the top of the positioning member, and the positioning groove 26 matches the size of the frame component corresponding to the positioning member, and is used for the positioning member to be inserted into the corresponding part of the frame 3, so as to achieve accurate positioning and stable support of the corresponding part when assembling the frame 3. Or a positioning hole 27 is provided on the top of the positioning member, and the frame component corresponding to the positioning member has a mounting hole, and the positioning hole 27 and the mounting hole can be passed through by the same pin shaft, so as to achieve accurate positioning and stable support of the frame component.

[0023] The plurality of positioning members are plate-shaped, which is convenient for laser cutting and also more convenient for the positioning members to be inserted into each other. The insertion and matching between the positioning members are vertical insertion, that is, the insertion direction of the inserted positioning member is perpendicular to the surface of the inserted positioning member, which effectively ensures the stability of the overall structure after the positioning members are inserted into each other.

[0024] The utility model also provides a frame tool for assembling a double wishbone suspension, the frame tool uses the above-mentioned frame tool assembly structure, that is, the frame tool is formed based on the above-mentioned assembly structure. Specifically, it includes a base plate 1 and a double wishbone suspension installation and positioning assembly 2, the double wishbone suspension installation and positioning assembly 2 is a component used to position the corresponding part on the frame 3 when the double wishbone suspension is installed, the double wishbone suspension installation and positioning assembly 2 includes a positioning member 21 for positioning and supporting the lower wishbone installation part 31, a positioning member 22 for positioning and supporting the upper wishbone installation part 32, and a positioning member 3 23 for positioning and supporting the upper support arm 33, the positioning member 21, the positioning member 22 and the positioning member 3 23 are all arranged on the base plate 1 and plugged with the base plate 1, and at least two of the positioning member 21, the positioning member 22 and the positioning member 3 23 are at an angle to each other and plugged in the horizontal and / or vertical directions. Among them, the plug-in fitting structure described in the frame tooling is specifically the same as the plug-in fitting structure in the aforementioned frame tooling assembly structure, the lower fork arm mounting portion 31 is the portion on the frame 3 used to connect with the lower fork arm in the double fork arm suspension, the upper fork arm mounting portion 32 is the portion on the frame 3 used to connect with the upper fork arm in the double fork arm suspension, and the upper support arm 33 is the portion on the frame 3 used to connect with the shock-absorbing spring in the double fork arm suspension.

[0025] The frame tooling for assembling the double wishbone suspension, due to the use of the above-mentioned frame tooling assembly structure, can convert the assembly accuracy from manual control to mechanical equipment during the assembly of the frame tooling, simplify the operation content of the assembly link, avoid the dependence of the traditional assembly method on the skills of the welding technician and the difficulty of manual control of the accuracy operation, and can achieve good error prevention based on the mutual cooperation of the plug-in structure, reduce the skill requirements for the welding technician, and reduce the cost. Since the positioning and mutual cooperation are achieved through the plug-in structure, the welding process only needs spot welding and local forging welding, and no full welding is required, which can reduce the welding deformation of the frame tooling and improve the assembly accuracy of the frame tooling, thereby improving the assembly accuracy of the frame 3 when the frame tooling is used. Based on the assembly and performance of the vehicle chassis, the suspension has a greater impact on the comfort and stability of the whole vehicle. By setting the double wishbone suspension installation positioning assembly 2 as the above-mentioned structure, not only the position accuracy of each positioning part during assembly is achieved, but also the structural stability between the positioning parts is increased, the deformation degree of the frame tooling under long-term use is reduced, and the accuracy of the frame tooling under long-term use is guaranteed, thereby ensuring the accuracy of the frame 3 assembled on the production line.

The positioning member 24 is perpendicular to and plugged with the positioning member 1 21, and the positioning member 5 25 is perpendicular to and plugged with the positioning member 2 22.

The positioning hole 27 and the mounting hole can be passed through by the same pin shaft to achieve accurate positioning and stable support of the upper arm 33. Since the shape and structure of the upper arm 33 are different from other components, this setting method can better meet the positioning and support of the upper arm 33 compared to the mounting groove.
