Description

Technical Field

[0001] The utility model relates to the technical field of automobile tailgate assembly tooling, in particular to a tailgate assembly tooling. Background Art

[0002] With the increase in the popularity of automobiles and the aesthetic standards of consumers, higher requirements are placed on the level of automobile manufacturing. The coordination of the gap surface difference of the exterior shape of the car directly affects the quality of the true expression of the shape intention. For example, the coordination of the gap surface difference between the back door and the body has always been a difficult point. If the gap between the back door and the left and right sides of the body is too large or asymmetrical, it will reduce the beauty of the shape; if the gap is too small, it is easy to cause closing interference, causing serious problems such as paint peeling and damage. These will directly affect consumers' experience of using the vehicle, and then affect the sales volume of the model. However, strict installation and adjustment standards will put great pressure on production, seriously affecting production capacity planning and production costs. For example, patent document CN113607037A discloses a car back door assembly alignment inspection aid, which provides a tooling structure for detecting the back door in the body assembly position, but the structure can only ensure the Z-direction relative relationship between the back door and the side wall, which can solve the problem of the surface difference between the back door and the side wall, but cannot solve the problem of the gap with the side wall in the Y direction. Another example is a tailgate assembly aid disclosed in patent document CN106672115A, which includes two first auxiliary assembly modules and two second auxiliary assembly modules; the first auxiliary assembly module includes a hand-held handle, a side panel profiling block, a first clamping block, a second clamping block, a third clamping block and a first magnet; the second auxiliary assembly module includes a top cover profiling block, a fourth clamping block and a second magnet; the fourth clamping block is fixed to the end of the top cover profiling block. However, the tooling has a large number of parts and requires a lot of manpower. In addition, the above tooling structures are all fixed structures, which cannot realize the conversion of different sizes and specifications. They can only be used for a certain model and cannot be shared by different models, which increases the investment cost of the tooling.

[0003] Therefore, it is necessary to develop a new back door assembly tool. Summary of the invention

[0049] like Fig. 9 and Fig.10 As shown, in the embodiment of the present application, the pin sleeve 5 is used for the tooling face difference specification. The pin sleeve 5 includes a pin sleeve body 55 having a pin sleeve hole 51, and a pin sleeve key 52 for correspondingly matching with the pin sleeve keyway 43 is provided on the inner wall of the pin sleeve body 55. The pin sleeve body 55 is provided with a pin sleeve engaging boss 54 for engaging with the pin sleeve engaging groove 16 at one end that matches with the step 17. A first pin sleeve fitting surface 53 with magnetism is provided between adjacent pin sleeve engaging bosses 54. Among them: the pin sleeve hole 51 is used for the face difference pin 4 to pass through. The pin sleeve key 52 is used to correspond to the pin sleeve keyway 43 of the face difference pin 4, allowing the pin sleeve 5 to slide along the axis, and allowing the pin sleeve 5 to drive the face difference pin 4 to rotate around the axis. The first pin sleeve fitting surface 53 is used to be attracted magnetically with the second pin sleeve fitting surface 15 on the tooling base 1. The pin sleeve engagement boss 54 is used to correspond to the pin sleeve engagement groove 16 on the tooling base 1, and the pin sleeve engagement groove 16 cooperates with the pin sleeve engagement boss 54 to limit the pin sleeve 5 from rotating freely around the axis.

[0050] like Fig.11As shown, in the embodiment of the present application, the pin cap 6 includes a pin cap body 63, and a pin cap bolt 61 is provided on the pin cap body 63. The pin cap 6 is installed on the upper end of the pin body 47 through the pin cap bolt 61. The pin cap 6 is used to seal the top of the flush pin 4 to form a closed structure to prevent the pin sleeve 5 from slipping and losing. Among them: the pin cap bolt 61 is used to tighten and match with the pin cap threaded hole 41 of the flush pin 4. The pin cap mounting surface 62 is used to fit and match with the pin cap mounting surface 42 of the flush pin 4.

[0051] In the embodiment of the present application, the pin cap 6, the pin sleeve 5, the boss 17, the flush pin threaded hole 14 and the flush pin thread 45 together form a height adjustment assembly. The flush pin 4 is installed on the tooling base 1 through the height adjustment assembly, and the height of the flush pin 4 is adjusted through the height adjustment assembly to change the relative height difference between the flush reference surface 46 of the flush pin 4 and the flush base surface 11 of the tooling base 1.

[0052] In the embodiment of the present application, the gap scale 2 is installed on the tooling base 1 by the scale bolt 3. When the scale bolt 3 is loosened, the gap scale 2 can rotate around its center to realize the switching of gap scales 23 of different specifications. The gap scales 23 of different specifications are used for different vehicle models or assembly requirements. After the switching is completed, the scale bolt 3 is tightened to lock it and fix the gap specification required for the assembly.

[0053] like Fig.12 As shown, in the embodiment of the present application, when the tailgate is installed using the tailgate assembly tool, the left and right operators insert the gap ruler 2 into the selected gap between the tailgate 9 and the vehicle body 8, and the tailgate 9, the gap ruler 2 and the vehicle body 8 fit together to ensure that the left and right gaps between the tailgate 9 and the vehicle body 8 are correct and symmetrical.

[0054] In the embodiment of the present application, the flush pin 4 is installed on the tooling base 1 through the pin sleeve 5 and the pin cap 6. The pin sleeve 5 is pulled out in the direction away from the tooling base 1, so that the pin sleeve engagement boss 54 is disengaged from the constraint of the pin sleeve engagement groove 16. The pin sleeve 5 is rotated, and under the cooperation of the pin sleeve key 52 and the pin sleeve keyway 43, the pin sleeve 5 drives the flush pin 4 to rotate, and under the cooperation of the flush pin thread 45 and the flush pin threaded hole 14, the rotational motion of the flush pin 4 around the axis is converted into a linear motion along the axis, thereby changing the relative height difference between the flush reference surface 46 and the flush base surface 11. The height difference corresponds to the flush scale 44, and different height difference specifications are used for different vehicle models or assembly requirements. After the switching is completed, the pin sleeve 5 is pressed back to the tooling base 1, and the pin sleeve engagement boss 54 re-engages with the pin sleeve engagement groove 16, which restricts the rotation of the pin sleeve 5, thereby restricting the rotation of the flush pin 4, so as to achieve the height difference change between the flush reference surface 46 and the flush base surface 11, thereby fixing the required flush specification for assembly. At the same time, the first pin sleeve abutment surface 53 and the second pin sleeve abutment surface 15 are attracted to each other by magnetism to prevent the pin sleeve 5 from falling off.

[0055] like Fig.12As shown, in the embodiment of the present application, when the tailgate is installed by using the tailgate assembly tool, the left and right operators fit the flush base surface 11 of the tool base 1 with the vehicle body 8, adjust the tailgate position, and fit the tailgate 9 with the flush reference surface 46 of the flush pin 4, so that the flushness between the tailgate and the vehicle body is consistent with the flushness specification set by the tool, thereby ensuring that the flushness between the tailgate and the left and right vehicle bodies is correct and symmetrical.

[0056] The above-mentioned embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above-mentioned embodiments. Any other changes, modifications, substitutions, combinations and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement modes and shall be included in the protection scope of the present invention.
