DETAILED DESCRIPTION

[0023] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model. Example

[0024] like Figures 1 to 4 As shown, the utility model provides a car hood closing, tightening and positioning tool, including a tool bracket 1, the tool bracket 1 is made of 7075 aluminum alloy, so that it can reduce the overall weight while meeting the strength and rigidity as a main frame, and is convenient for manual handling and lifting. Support mechanisms, positioning mechanisms and closing and tightening mechanisms are provided at both ends of the length direction of the tool bracket 1. The support mechanism includes a body support block 2, a hood support block 1 3 and a hood support block 2 4. The hood support block 1 3 and the hood support block 2 4 are opposite to the body support block 2. The positioning mechanism includes a hood positioning piece 5 and a fender positioning piece 6. The hood positioning piece 5 and the fender positioning piece 6 are opposite to each other.

[0025] like Figures 1 to 4 As shown, a mounting plate 1 7 and a mounting plate 2 8 are fixedly connected to the bottom surface of the tooling bracket 1, and the mounting plate 1 7 and the mounting plate 2 8 are respectively located at the two ends of the Y direction of the tooling bracket 1, and the hood support block 1 3 and the fender positioning member 6 are detachably connected to the mounting plate 1 7, the hood support block 1 3 is located on the bottom surface of the mounting plate 1 7 and is arranged along the Y direction of the tooling bracket 1, and the fender positioning member 6 is located on the top surface of the mounting plate 1 7 and is arranged along the X direction of the tooling bracket 1.

[0026] like Figures 1 to 4 As shown, the hood positioning member 5, the hood supporting block 24, the vehicle body supporting block 2 and the closing and tightening mechanism are located on the mounting plate 28, the hood positioning member 5 and the closing and tightening mechanism can be detachably connected to the top surface of the mounting plate 28 and both are respectively located at the two ends of the mounting plate 28 in the Y direction, the closing and tightening mechanism is located at the end of the mounting plate 28 away from the mounting plate 1 7, the hood supporting block 24 is detachably connected to the bottom surface of the mounting plate 28, the number of the closing and tightening mechanisms on one end of the tooling bracket 1 is two groups, and the vehicle body supporting block 2 is located on the bottom surface of one group of the closing and tightening mechanisms.

[0027] The tool is placed on the hood compartment of the car, so that the fender positioning members 6 on both ends of the tool bracket 1 are directly positioned at the fender to determine the position of the tool bracket 1 in the X direction and the Y direction, and the matching relationship is more direct. At the same time, the body support block 2 is directly against the parts in the hood compartment of the car, and the fender positioning members 6 support the tool bracket 1 to determine the position of the tool bracket 1 in the Z direction. Then the hood is closed on the car, and the hood is lifted up by the hood support block 1 3 and the hood support block 2 4. The hood positioning members 5 determine the relative position of the tool bracket 1 and the hood in the X direction and the Y direction. At this time, the matching relationship between the hood, the fender and the door can be directly observed, and the installation clearance and surface difference of the hood can be measured to see whether they meet the requirements.

[0028] like Figures 1 to 4 As shown, the closing and tightening mechanism includes a positioning shell 9 and a transmission member 10. The positioning shell 9 is detachably connected to the mounting plate 8. The transmission member 10 is located in the positioning shell 9 and both ends thereof extend out from the positioning shell 9. The two ends of the transmission member 10 are respectively an input end 11 and an output end 12. The positioning shell 9 is abutted against the transmission member 10 through a plurality of elastic plungers 13. The plurality of elastic plungers 13 horizontally penetrate the outer wall of the positioning shell 9.

[0029] After the hood is positioned, the input end 11 of the transmission member 10 can be tightened by an automatic tightening tool between the hood and the front windshield of the vehicle body, thereby achieving a tightening effect at its output end 12. In this process, the transmission member 10 will vibrate to a certain extent, and the elastic plunger 13 on the positioning shell 9 can limit and buffer the vibration of the transmission member 10 in the X and Y directions through elastic force, so that the transmission member 10 is located in the center of the positioning shell 9 without being subjected to external force, and can be used to absorb the deviation of the stud position of the vehicle body and the hood.

[0030] like Figures 1 to 4 As shown, a connecting plate 14 is fixedly connected to the tooling bracket 1, and an auxiliary positioning member 15 is slidably connected to the connecting plate 14. The auxiliary positioning member 15 is located at the hollow part of the tooling bracket 1, and the auxiliary positioning member 15 is slidably connected to the connecting plate 14 through an extension plate 16. A slide rail is provided on the extension plate 16, and a slider located in the slide rail is provided on the connecting plate 14. A protrusion 17 is also provided on the extension plate 16, and a limiting plunger 18 for abutting against the protrusion 17 is provided on the connecting plate 14.

[0031] The auxiliary positioning member 15 is used to determine the position of the tooling bracket 1 and the vehicle body in the X direction and the Y direction. Although the hood positioning member 5 and the fender positioning member 6 have completed the positioning of the tooling bracket 1, the pin and the hole must be matched with clearance. The tiny clearance will cause the distant position to amplify the leverage ratio and affect the matching position of the hood. Therefore, the auxiliary positioning member 15 is added to effectively reduce the leverage ratio here.

[0032] like Figures 1 to 4 As shown, the tooling bracket 1 is placed in the hood compartment of the automobile, so that the fender positioning members 6 on both ends of the tooling bracket 1 are directly positioned at the fender to determine the position of the tooling bracket 1 in the X direction and the Y direction. At the same time, the body support block 2 directly abuts against the parts in the hood compartment of the automobile, and the fender positioning members 6 support the tooling bracket 1 to determine the position of the tooling bracket 1 in the Z direction. The auxiliary positioning members 15 added to the tooling bracket 1 are used to further determine the position of the tooling bracket 1 and the body in the X direction and the Y direction. Then, the hood is closed on the automobile, and the hood is lifted up by the hood support block 1 3 and the hood support block 2 4, while the hood positioning members 5 are used to determine The relative position of the fixture bracket 1 and the hood in the X direction and the Y direction can be determined. At this time, the matching relationship between the hood, the fender and the door can be directly observed, and the installation clearance and the surface difference of the hood can be measured to see whether they meet the requirements. If they meet the requirements, they can be tightened and positioned at the input end 11 of the transmission member 10. This operation is performed when the hood is closed, and it can be adjusted at any time to shorten the operation time and reduce the adjustment amount of the subsequent process. After the connection between the hood and the body is completed, the hood can be opened to take out the fixture. This method can reduce costs, reduce gas consumption, improve energy utilization, improve production efficiency, reduce subsequent adjustments, and reduce the outflow of defective products.
