[0029] To enable those skilled in the art of the present technology to better understand the technical solution of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] The present application provides an assembly and adjustment auxiliary tooling for a hood and a fender.

[0031] As Figure 1 shown, in this embodiment, the assembly and adjustment auxiliary tooling for the hood and the fender (hereinafter referred to as the tooling) includes a base body 10, a base body positioning portion 20, a hood positioning portion 30, and a fender positioning portion.

[0032] The base body positioning portion 20 is fixed to the base body 10. The base body positioning portion 20 includes two sets of base body positioning components, and the two sets of base body positioning components are respectively located on both sides of the longitudinal center line (L in the figure) of the vehicle. Each set of base body positioning components includes a base body positioning pin 201 and a base body positioning block 202. The base body positioning pin 201 cooperates with the headlight positioning hole ( Figure 2 indicated by A in the figure) of the vehicle body frame to achieve the longitudinal and lateral positioning of the base body 10. The lower surface of the base body positioning block 202 abuts against the front side area and the rear side area of the headlight frame support surface ( Figure 2 indicated by B and C in the figure) of the vehicle body frame 01 respectively to achieve the vertical positioning of the base body 10. Thereby, the relative position between the base body 10 and the vehicle body frame is fixed.

[0033] Both the hood positioning portion 30 and the fender positioning portion are fixed to the base body 10. The hood positioning portion 30 cooperates with the hood 02 to achieve the positioning of the hood. The fender positioning portion cooperates with the fender 03 to achieve the positioning of the fender.

[0034] When assembling and adjusting the hood and the fender, first fix the relative position between the base body 10 and the vehicle body frame. Since both the hood positioning portion 30 and the fender are fixed to the same base body 10, after the relative position between the base body 10 and the vehicle body frame is fixed, the positions of the hood positioning portion 30 and the fender positioning portion are fixed. Then, make the mating portion of the hood cooperate with the hood positioning portion 30, and make the mating portion of the fender cooperate with the fender positioning portion, so as to assemble and adjust the hood and the fender.

[0035] In the past, the fender was first adjusted using a fender adjustment auxiliary tooling, and then the hood was adjusted using a hood adjustment auxiliary tooling. Since the fixing references of the fender adjustment auxiliary tooling and the hood adjustment auxiliary tooling relative to the vehicle body frame are different, a reference conversion is required, which may lead to deviations in the consistency of the two adjustments. As a result, further adjustments are needed after the two adjustments to correct the deviations, affecting the vehicle assembly rhythm. Moreover, after the adjustment, the matching accuracy between the fender and the headlight cannot be guaranteed, affecting the vehicle assembly quality. However, for the above tooling provided in this application, since both the hood positioning portion 30 and the fender positioning portion are fixed relative to the vehicle body frame through the same base body 10, the fixing references of the hood positioning portion 30 and the fender positioning portion relative to the vehicle body frame are the same. Therefore, the consistency deviation caused by the reference conversion in the hood adjustment and the fender adjustment is avoided, and no further adjustment is needed to correct the deviation. Thus, the vehicle assembly rhythm is accelerated. In addition, since the base body 10 is fixed by the base body positioning portion 20 in cooperation with the headlight positioning holes and the headlight frame support surface of the vehicle body frame, the matching accuracy between the fender and the headlight can be guaranteed after the adjustment, thereby improving the vehicle assembly quality.

[0036] In some embodiments, each group of base body positioning components includes a plurality of base body positioning blocks 202. The term "a plurality" means two or more. For example, in the illustrated embodiment, each group of base body positioning components includes two base body positioning blocks 202. Among them, one base body positioning block 202 is located behind the base body positioning pin 201, and the lower surface of this base body positioning block 202 abuts against the rear region of the headlight frame support surface of the vehicle body frame ( Figure 2 the region indicated by C in the figure), and the other base body positioning block 202 is located in front of the base body positioning pin 201, and the lower surface of this base body positioning block 202 abuts against the front region of the headlight frame support surface of the vehicle body frame ( Figure 2 the region indicated by B in the figure). In this way, the relative position between the base body 10 and the vehicle body frame is more stable. In the figure, the front base body positioning block 202 is located in front of the base body 10, the rear base body positioning block 202 is located behind the base body 10, and the base body positioning pin 201 is located below the base body 10.

[0037] In some embodiments, the base body positioning pin 201 of a group of base body positioning components is a circular base body positioning pin 201. The circular base body positioning pin 201 realizes the longitudinal and lateral positioning of the base body 10 by cooperating with the headlight positioning holes. The base body positioning pin 201 of another group of base body positioning components is a rhombic base body positioning pin 201. The long axis of the rhombic base body positioning pin 201 is along the vehicle width direction. The rhombic base body positioning pin 201 realizes the longitudinal positioning of the base body 10 by cooperating with the headlight positioning holes, avoiding the over-positioning of the base body 10 in the lateral direction and improving the assembly tolerance between the base body 10 and the vehicle body frame.

[0038] Figure 7Disclosed is a diamond locating pin, which includes a threaded post section D1, a fan-shaped plate D2 located at one end of the threaded post section D1, and a diamond-shaped pin head D3 located on the side of the fan-shaped plate D2 away from the threaded post section D1. It is fixedly installed through the threaded post section D1 and positioned by the cooperation of the diamond-shaped pin head D1 with the corresponding hole. Figure 8 In it, L1 is the major axis of the diamond locating pin.

[0039] In some embodiments, such as Figure 1 shown, the hood positioning part 30 includes two groups of hood positioning components, and the two groups of hood positioning components are respectively located on both sides of the longitudinal center line of the vehicle. Each group of hood positioning components includes a hood positioning pin 301 and a hood positioning block 302. As Figure 3 shown, the hood positioning pin 301 cooperates with the pin hole of the hood to position the longitudinal and transverse positions of the hood. The upper surface of the hood positioning block 302 abuts against the lower surface of the hood to support the hood and position the vertical position of the hood. The upper surface of the hood positioning block 302 can be profiled with the lower surface of the hood so that the two can abut in a surface contact form.

[0040] The conventional hood assembly and adjustment auxiliary tooling does not position the hood, but positions the hinge mechanism connecting the hood. The adjustment amount is obtained by measuring the hood. After obtaining the adjustment amount, it is necessary to convert it into the adjustment amount of the hinge mechanism, and then the hood is assembled and adjusted by adjusting the hinge mechanism. The conversion will not only increase the difficulty of assembly and adjustment but also increase the assembly and adjustment deviation.

[0041] However, in this application, the hood is directly positioned by using the hood positioning part 30. After obtaining the adjustment amount by measuring the hood, the hood can be directly adjusted without conversion. Therefore, the difficulty of assembly and adjustment and the assembly and adjustment deviation can be reduced.

[0042] In some embodiments, each group of hood positioning components includes a plurality of hood positioning blocks 302. The term "a plurality" means two or more. For example, in the illustrated embodiment, each group of hood positioning components includes two hood positioning blocks 302. Among them, one hood positioning block 302 is located behind the hood positioning pin 301, and the lower surface of this hood positioning block 302 abuts against the rear area of the headlight frame support surface of the vehicle body frame ( Figure 2 the area indicated by C in it), and one hood positioning block 302 is located in front of the hood positioning pin 301, and the lower surface of this hood positioning block 302 abuts against the front area of the headlight frame support surface of the vehicle body frame ( Figure 2 the area indicated by B in it). In this way, the positioning of the hood is more reliable. In the figure, the hood positioning block 302 is located above the base body 10 and is connected to the base body 10 through a bracket. The height of the rear hood positioning block 302 is lower than the height of the front hood positioning block 302.

[0043] In some embodiments, the hood positioning pin 301 of a set of hood positioning components is a circular hood positioning pin 301. By cooperating with the headlight positioning hole, the longitudinal and lateral positioning of the hood is achieved. The hood positioning pin 301 of another set of hood positioning components is a diamond-shaped hood positioning pin 301. The major axis of the diamond-shaped hood positioning pin 301 is along the vehicle's transverse direction. By cooperating with the headlight positioning hole, the longitudinal positioning of the hood is achieved, avoiding the transverse over-positioning of the hood and improving the assembly tolerance between the hood and the hood positioning part.

[0044] In some embodiments, such as Figure 6 shown, the fender positioning components include a fender positioning block 401, and the fender positioning block 401 has a first positioning surface 202a and a second positioning surface 202b. As Figure 5 shown, the first positioning surface 202a abuts against the upper surface of the fender to achieve the vertical positioning of the fender, and the second positioning surface 202b abuts against the surface of the fender close to the vehicle body to achieve the lateral positioning of the fender. The first positioning surface 202a can be profiled to the upper surface of the fender so that the two can abut in a surface contact form, and the second positioning surface 202b can be profiled to the surface of the fender close to the vehicle body so that the two can abut in a surface contact form.

[0045] In the past, the fender assembly and adjustment tooling only performed lateral positioning on the fender and did not perform vertical positioning on the fender, resulting in greater assembly and adjustment difficulty and deviation of the fender.

[0046] This application not only performs lateral positioning on the fender but also performs vertical positioning on the fender, reducing the assembly and adjustment difficulty and deviation of the fender.

[0047] In some embodiments, each set of fender positioning components includes a plurality of fender positioning blocks 401. The term "a plurality" means two or more. For example, in the illustrated embodiment, as Figure 4 shown, each set of fender positioning components includes two fender positioning blocks 401. One of the fender positioning blocks 401 abuts against the upper surface and the surface close to the vehicle body of the front side region of the fender, and the other fender positioning block 401 abuts against the upper surface and the surface close to the vehicle body of the rear side region of the fender. In this way, the positioning of the fender is more reliable. In the figure, the two fender positioning blocks 401 of the fender positioning component on the left are located to the left of the base 10, and the two fender positioning blocks 401 of the fender positioning component on the right are located to the right of the base 10.

[0048] In some embodiments, such as Figure 1As shown, the base body 10 is a frame structure, including two cross beams 101 extending along the vehicle width direction and multiple longitudinal beams 102 extending along the vehicle length direction and connected between the two cross beams 101. The term "multiple" means two or more, and there are four in the figure. Reinforcing plates 103 can be provided at the joints of the longitudinal beams 102 and the cross beams 101. The longitudinal beams 102 can be provided with weight reduction holes. The base body 10 of the frame structure has a light self-weight and high strength. In actual implementation, the base body 10 is not limited to the frame structure. For example, it can also be a plate structure.

[0049] The above uses specific examples to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can also be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
