[0040] Example

[0041] The technical solution of the present invention will be described in detail below through embodiments. The following embodiments are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being construed as a limitation to the technical solution of the present invention.

[0042] This embodiment provides a side door fixture with adjustable Z-direction height. As Figure 1 shown, it includes a fish-mouth positioning part 1, a fish-mouth positioning part mounting plate 2, a first clamping handle 3, a second clamping handle 4, a fixture main body 5, and a fixture handle 6. Among them, the fish-mouth positioning part 1 is fixedly connected to the fish-mouth positioning part mounting plate 2, and the fish-mouth positioning part mounting plate 2 is fixedly connected to the fixture main body 5. The fixture main body 5 can be structurally fitted to the door mounting position of the vehicle body. The first clamping handle 3 and the second clamping handle 4 are fixedly connected to the fixture main body 5, so that the fixture provided in this embodiment can be fixedly connected to the vehicle body to achieve the positioning and installation of the door. The fixture handle 6 is fixedly connected to the fixture main body 5 and is used to lift and place the fixture provided in this embodiment.

[0043] Regarding the design of the fish-mouth positioning part 1, as Figure 2 、 3 shown, it includes a fish-mouth insert 11, a fastening bolt 12, a top support block 13, a substrate scale 14, a bottom adjustment gasket 15, a top adjustment gasket 16, and a vehicle body positioning pin 17. Among them, two longitudinally parallel strip-shaped grooves are provided at the front of the fish-mouth insert 11, and the fastening bolts 12 are respectively arranged in the strip-shaped grooves. Tightening the fastening bolts 12 can press the fish-mouth insert 11 towards the fish-mouth positioning part mounting plate 2. The design of the top support block 13 can make the fish-mouth insert 11 locked and not loosened after being fixed. Specifically, there is a groove on the back of the top support block 13, which presents a "匚" shape in side view and is clamped between the fish-mouth insert 11 and the fish-mouth positioning part mounting plate 2. And the longitudinal length of the groove on the back of the top support block 13 is longer than the height of the fish-mouth positioning part mounting plate 2. If only the groove on the back of the top support block 13 is buckled on the fish-mouth positioning part mounting plate 2, there are still gaps above and below the groove, so that the top support block 13 can move up and down relative to the fish-mouth positioning part mounting plate 2. A bottom adjustment gasket 15 is arranged in the bottom gap of the groove on the back of the top support block 13, and a top adjustment gasket 16 is arranged in the top gap, which are used to fill the gap of the groove on the back of the top support block 13, so that after the positioning of the top support block 13 is completed, the bottom adjustment gasket 15 and the top adjustment gasket 16 are filled to play a limiting role on the top support block 13. In addition, top support locking bolts are arranged at the top and bottom of the top support block 13 to lock the top support block 13. The substrate scale 14 is arranged on the fish-mouth positioning part mounting plate 2 and is used to observe the Z-direction height information. The vehicle body positioning pin 17 is fixed on the back of the fish-mouth positioning part mounting plate 2 and is used to achieve the positioning of the fixture provided in this embodiment and the vehicle body.

[0044] This embodiment can more accurately adjust the Z-direction height of the door mounted on the vehicle body by steplessly adjusting the position of the fish mouth insert 11. The adjustment steps for the fish mouth insert 11 are as follows:

[0045] 1. Loosen the top support locking bolts and fastening bolts 12 of the top support block 13 and adjust the fish mouth insert 11 to the target height;

[0046] 2. Tighten the fastening bolts 12 to fix the fish mouth insert 11;

[0047] 3. According to the position of the fish mouth insert 11, adjust the number of the bottom adjustment gasket 15 and the top adjustment gasket 16, lock the upper and lower support locking bolts to clamp the fish mouth insert 11 again to prevent the fish mouth insert 11 from shifting up and down during use.

[0048] The following is an introduction to the method of using the fixture provided in this embodiment. First, the fixture is positioned by the vehicle body locating pin 17. After positioning, the first clamping handle 3 and the second clamping handle 4 are controlled to fix the fixture to the vehicle body. Then, the positioning pins and the fish-mouth insert 11 on the door hinge are used to complete the positioning of the door and the vehicle body. Finally, after the positioning is completed, the hinge bolts are manually tightened to complete the installation of the door on the vehicle body. When the Z-direction height of the door installed on the vehicle body cannot meet the height dimension requirements, the operator optimizes the Z-direction height position of the fish-mouth insert 11 according to the installation status of the vehicle body. After the optimization is completed, the door is tried again until it meets the positioning requirements, and the position of the fish-mouth insert 11 is solidified; after the position of the fish-mouth insert 11 is solidified, the fixture can be delivered to the production line for mass production.

[0049] Preferably, the fish mouth positioning portion mounting plate 2 and the harness trunk 5 are made of aluminum alloy to reduce the weight of the harness provided in this embodiment and achieve lightweight harness.

[0050] The above describes the specific embodiments of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the scope of the technical concept of this invention.
