[0028] See Figure 1 as shown;

[0029] A front hood positioning tool on a Cubing model of the utility model includes: a tool body 1;

[0030] The tool body 1 includes a base frame 101 and a bracket 102 fixedly connected to the top end of the base frame 101 and extending obliquely upward. The overall shape of the base frame 101 is a triangular prism structure, and the bracket 102 is a triangular frame structure and is fixedly connected to the top end of the base frame 101 obliquely;

[0031] The bottom end of the base frame 101 has a first base surface, and the first base surface is located on the side of the Cubing model;

[0032] A second base surface is formed on the side of the bracket 102 away from the base frame 101, and the second base surface is located on the side of the front hood;

[0033] Among them, a backing plate is fixedly connected to the first base surface, and the backing plate forms a tooling reference surface for contacting the Cubing model through a cushion block to control the Z direction of the tooling. See Figure 2As shown in Fig. b, the tooling reference plane includes tooling reference planes 8 and 9, and is arranged along the edge of the first base plane of the base frame 101. A tooling positioning pin and a fastening mechanism 11 are also fixedly connected to the backing plate. The base frame 101 is fixedly connected to the Cubing model through the fastening mechanism 11. The fastening mechanism 11 is a fastening handle or a quick clamp in the prior art, and can realize the detachable fixed connection between the base frame 101 and the Cubing model. The tooling positioning pin includes a first tooling positioning pin 9 and a second tooling positioning pin 10. The X and Y directions of the tooling are controlled by the cooperation of the first tooling positioning pin 9 and the second tooling positioning pin 10 with the positioning holes of the Cubing model;

[0034] Among them, positioning posts are evenly distributed at the edge position of the second base plane. The top of the positioning post forms a front hood positioning surface that contacts the front hood. Refer to Figure 2 As shown in Fig. a, the front hood positioning surface includes a first front hood positioning surface 2, a second front hood positioning surface 3, and a third front hood positioning surface 4, and is arranged at intervals along the edge position of the second base plane of the bracket 10. An auxiliary positioning pin is fixedly connected to the positioning surface, and a support block is fixedly connected to the middle of the second base plane. A telescopic front hood positioning pin 5 is installed on the support block, and a control rod 6 is installed on the side of the support block. The telescopic front hood positioning pin 5 is driven to expand and contract and be positioned through the control rod 6. By adding a telescopic front hood positioning pin 5 to this tooling, it is convenient for loading and unloading the front hood, and realizes the full restriction of six degrees of freedom of the front hood, ensuring the accuracy and consistency of the assembly of the front hood and the Cubing model, and improving the efficiency.

[0035] To facilitate the movement of this tooling, preferably, the tooling further includes two handles 12, and the handles 12 are fixedly connected to the side of the top of the base frame 101 away from the second base plane of the bracket 102.

[0036] Preferably, there are two tooling bodies 1, which are symmetrically distributed on both sides of the front hood. Specifically, the front hood positioning surfaces, front hood positioning pins, tooling reference planes, and tooling positioning pins on the two tooling bodies 1 are symmetrically arranged to support the front hood in a symmetric form.

[0037] In the above technical solution, a front hood positioning tooling on a Cubing model provided by the present invention has an assembly and positioning method as follows:

[0038] The positioning method of this tooling on the Cubing model is shown in Figure 4 shown;

[0039] The tooling is positioned on the Cubing model through the first tooling reference plane 7 and the second tooling reference plane 8 to control the Z direction. The tooling is positioned and placed on the Cubing model through the first tooling positioning pin 9 and the second tooling positioning pin 10 to control the X and Y directions. The tooling is fixed on the Cubing model through the fastening mechanism 11. The positioning and fixing methods of the two symmetric tooling bodies 1 are the same;

[0040] The positioning method of the front engine cover on the tooling is shown in Figure 5 the following figure;

[0041] The front engine cover is positioned on the tooling through the front engine cover positioning surfaces 2, 3, and 4 on two tooling bodies to control the Z direction, and the X and Y directions are controlled by the front engine cover positioning pin 5, so that the front engine cover is positioned in all three directions on the tooling. Moreover, by adding a retractable front engine cover positioning pin 5 to this tooling, it is convenient for loading and unloading the front engine cover, and all six degrees of freedom of the front engine cover are fully restricted, ensuring the accuracy and consistency of the assembly of the front engine cover and the Cubing model, and improving the efficiency.
