[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] A rear door hinge tightening and positioning tool, such as Figures 1 to 6 As shown, the hanger 1 includes two first positioning pins 2 and three fixing components 3 corresponding to the rear of the vehicle, the two first positioning pins 2 are distributed along the height direction of the hanger 1, the line connecting the three fixing components 3 is a triangle, the line connecting the two first positioning pins 2 and the three fixing components 3 is a pentagon, the center of the hanger 1 is provided with a tensioning component 4 corresponding to the rear of the vehicle, both sides of the tensioning component 4 are provided with positioning clamping components 5 for clamping hinges, and the two positioning clamping components 5 are arranged along the height direction of the hanger 1.

[0021] In the above embodiment, the two first locating pins 2 position the hanger 1 at the rear of the vehicle, and then the hanger 1 is fixedly clamped by the three fixing components 3. Since the connecting line of the two first locating pins 2 and the three fixing components 3 is a pentagon, the hanger 1 is positioned along the height and width directions of the vehicle body by the two first locating pins 2 and the three fixing components 3, and then the hanger 1 is positioned along the length direction of the vehicle body by the tensioning component 4, and then the upper and lower hinges are clamped corresponding to the rear of the vehicle by the two positioning clamping components 5, thereby achieving the effect of accurately positioning the hinge.

[0022] refer to Figure 3 As shown: the fixing assembly 3 includes a first mounting plate 14 connected to the hanger 1, a support rod 15 is welded to one side of the first mounting plate 14, a flip cylinder 16 is installed on the side of the first mounting plate 14 away from the support rod 15 by bolts, and a second clamping rod 17 corresponding to the support rod 15 is installed on the driving end of the flip cylinder 16 by bolts.

[0023] In the above embodiment, the second clamping plate is driven by the flip cylinder 16 to cooperate with the support rod 15 to clamp the rear end of the vehicle, thereby achieving the effect of positioning the hanger 1 at the rear end of the vehicle.

[0024] refer to Figure 5 and Figure 6 As shown: the tensioning assembly 4 includes two L-shaped hooks 18, a second mounting plate 19 is bolted on the hanger 1, a mounting sleeve 20 is bolted on the second mounting plate 19, a cross bar 21 is fixedly installed on the inner shaft hole of the mounting sleeve 20, and the two hooks 18 are provided with arc-shaped slots 22 corresponding to the cross bar 21. The two hooks 18 are arranged in opposite directions, and a clamping cylinder 23 is bolted on the mounting sleeve 20, and the ends of the two hooks 18 are rotatably connected to the drive end shaft holes of the clamping cylinder 23.

[0025] In the above embodiment, the two L-shaped hooks 18 are pushed to slide along the inner wall of the mounting sleeve 20 by driving the clamping cylinder 23. Due to the cooperation between the arc-shaped slot 22 and the cross bar 21, the two hooks 18 are dispersed outward. When the hanger 1 is positioned, the clamping cylinder 23 drives the hooks 18 to be tightened with the rear of the vehicle, thereby achieving the positioning of the hanger 1 along the length direction of the vehicle body.

[0026] refer to Figure 4 As shown: the positioning clamping assembly 5 includes a mounting frame 6 fixedly connected to the hanger 1, and linear drivers 7 are fixedly installed on both sides of the mounting frame 6 by bolts. The two linear drivers 7 are arranged along the thickness direction of the hanger 1, and two second positioning pins 8 and two first clamping rods 9 are respectively installed on the driving ends of the two linear drivers 7 by bolts, and the first clamping rods 9 are provided with through holes 10 corresponding to the second positioning pins 8;

[0027] A support plate 11, a support block 12 and two positioning blocks 13 arranged along the height direction of the hanger 1 are welded on the mounting frame 6, and the connecting line of the support plate 11, the support block 12 and the two positioning blocks 13 is trapezoidal.

[0028] In the above embodiment, the hinge is supported by the support plate 11, the support block 12 and the two positioning blocks 13 arranged along the height direction of the hanger 1, and then the hinge is clamped by driving the two linear drivers 7 to drive the two second positioning pins 8 to slide and cooperate with the two first clamping rods 9. Since the first clamping rod 9 is provided with a through hole 10 corresponding to the second positioning pin 8, the through hole 10 on the first clamping rod 9 and the second positioning pin 8 position the hinge.

[0029] Working principle:

[0030] The staff will pre-place the upper and lower hinges to be installed on the support plates 11, support blocks 12 and two positioning blocks 13 on the two positioning clamping assemblies 5, and then drive the two linear actuators 7 to drive the two second positioning pins 8 to slide and the two first clamping rods 9 to clamp the hinges, so that the through holes 10 on the first clamping rods 9 and the second positioning pins 8 position the hinges, and then push the hanger 1 so that the two first positioning pins 2 on the hanger 1 correspond to the rear of the vehicle, and then drive the flip cylinder 16 to push the second clamping plate and the support plate 11 to move the two first positioning pins 2 on the hanger ... The rod 15 cooperates to clamp the rear end of the vehicle, thereby positioning the hanger 1 at the rear end of the vehicle, and then the two L-shaped hooks 18 are pushed to slide along the inner wall of the mounting sleeve 20 by driving the clamping cylinder 23. Due to the cooperation of the arc-shaped slot 22 and the cross bar 21, the two hooks 18 are dispersed outward. When the hanger 1 is positioned, the hooks 18 are tightened with the rear end of the vehicle by the clamping cylinder 23, thereby positioning the hanger 1 along the length direction of the vehicle body, so that the upper and lower hinges can correspond to the mounting part of the rear end of the vehicle for installation, thereby improving the installation accuracy of the hinge.
