Since the vehicle door is frameless, the state of the upper part of the vehicle door (the position of the door frame of the original framed vehicle door) cannot be evaluated and controlled in the welding workshop. In the welding workshop, since the matching of the upper part of the vehicle door is lacking, the adjustment of the front and rear doors can only be used to determine the posture of the vehicle door, and it is difficult to achieve precise adjustment of the frameless vehicle door, thereby affecting the matching state of the frameless vehicle door glass system in the assembly workshop.

[0035] For the convenience of description, in the embodiments of the present disclosure, the vertical direction is defined as the Z direction, the vehicle wheelbase direction is defined as the X direction, and the direction of the line connecting the two front wheels of the vehicle is defined as the Y direction, and the X direction, Y direction and Z direction are perpendicular to each other.

[0036] The present disclosure provides a frameless door detection tool, see Figures 1-6The frameless door detection tool includes a tool body 1, a positioning installation structure, a first profiling block 2 and a second profiling block 3. The positioning installation structure is arranged on a first surface of the tool body 1 and matches the vehicle B column structure, and is used to connect the tool body with the vehicle B column during detection. The first profiling block 2 and the second profiling block 3 are arranged on a second surface of the tool body 1 opposite to the first surface. The outer surfaces of the first profiling block 2 and the second profiling block 3 away from the second surface match the outer surfaces of the doors to be detected, and are used to realize Y-direction adjustment of the doors. The lower parts of the first profiling block 2 and the second profiling block 3 protrude from the tool body 1, and the lower edges match the water-cut joint surfaces of the doors to be detected, and are used to realize Z-direction adjustment of the doors.

[0037] The frameless door detection tool provided by the embodiment of the present disclosure can simultaneously detect and adjust front and rear doors on one side of a vehicle through the first profiling block and the second profiling block arranged on the tool body. The lower surfaces of the first profiling block and the second profiling block are used to match the water-cut joint surfaces of the doors. The relative distance between the first profiling block, the second profiling block and the water-cut joint surfaces of the doors can be used to determine the Z-direction installation condition of the doors. The outer surfaces of the first profiling block and the second profiling block match the shapes of the outer surfaces of the doors. The relative positional relationship between the first profiling block, the second profiling block and the outer surfaces of the doors can be used to determine the Y-direction installation condition of the doors. The Y-direction and Z-direction installation conditions of the front and rear doors can be simultaneously detected and adjusted by using one tool, and the detection efficiency is greatly improved.

[0038] The frameless door detection tool provided by the embodiment of the present disclosure is used to assist in detecting the state of the frameless door after adjustment in a welding workshop. After the front and rear doors are adjusted and qualified in the welding workshop, the state of the water-cut joint surface of the outer weather strip is detected by the detection tool, so as to maximize the conformity of the door assembly. Through detection, the qualification and stability of the frameless door after adjustment in the welding workshop are increased, and the matching quality of the frameless door glass system in the assembly workshop is indirectly improved.

[0039] The positioning installation structure includes a first positioning pin 41 and a second positioning pin 42. The first positioning pin 41 matches a positioning hole 51 of a vehicle B column trim plate, and the second positioning pin 42 matches a buckle installation hole 52 of the vehicle B column trim plate. The first positioning pin 41 and the second positioning pin 42 are both fixedly installed on the tool body through nuts. Meanwhile, a strong magnet 43 is pre-embedded on the tool body. After the tool is positioned through the first positioning pin 41 and the second positioning pin 42, the tool and the vehicle B column can be attached together through the magnet 43, so as to prevent the tool from falling. In addition, a handle 6 is arranged on the tool body, which is used to facilitate taking.

[0040] For the convenience of description, in the embodiment, the direction shown in the drawings is taken as an example, and the profiling block on the left side is referred to as the first profiling block, and the profiling block on the right side is referred to as the second profiling block. Figure 1 For the convenience of description, in the embodiment, the direction shown in the drawings is taken as an example, and the profiling block on the left side is referred to as the first profiling block, and the profiling block on the right side is referred to as the second profiling block. Figure 1The right profiling block is referred to as a second profiling block; the first profiling block is used to detect the front door of the vehicle, and the front door of the vehicle is referred to as a first door; and the second profiling block is used to detect the rear door of the vehicle, and the rear door of the vehicle is referred to as a second door.

[0041] The first profiling block and the second profiling block are both fixedly installed on the tool body by installation screws. In a possible implementation, the second surface of the tool body is provided with a first groove 11 and a second groove 12, and the first profiling block 2 and the second profiling block 3 are fixedly installed at the first groove 11 and the second groove 12, respectively. The first profiling block and the second profiling block are both L-shaped, and the lower part protrudes from the tool body, for realizing Z-direction detection. In order to avoid interference between the first profiling block and the second profiling block and the door when the door assembly has a deviation and the first profiling block and the second profiling block are installed after the frameless door detection tool, the groove bottoms of the first groove and the second groove are both designed as inclined surfaces, that is, the groove depth of the upper part of the first groove and the second groove is greater than the groove depth of the lower part. At this time, when the first profiling block and the second profiling block are installed in the first groove and the second groove, the position of the first profiling block and the second profiling block that exceeds the tool body gradually increases compared to the distance between the tool bodies, thereby expanding the relative distance with the door.

[0042] The outer surfaces of the first profiling block and the second profiling block are both matched with the shape of the door, and the door is profiled, so that whether the Y-direction installation of the door meets the requirements can be directly judged according to the relative positional relationship between the outer surfaces of the first profiling block and the second profiling block and the first door and the second door. In a possible implementation, the outer surface of the first profiling block 2 away from the second surface of the tool body has a first curved surface 21, and the shape of the first curved surface is matched with the shape of the outer surface of the first door; and the outer surface of the second profiling block 3 away from the second surface of the tool body has a second curved surface 31, and the shape of the second curved surface is matched with the shape of the outer surface of the second door. In actual use, the first curved surface and the second curved surface can also be simply designed as inclined surfaces to facilitate measurement. By measuring the relative step difference between the first curved surface, the second curved surface and the first door, the second door, the Y-direction position of the first door, the second door can be adjusted according to the step difference.

[0043] The disclosure embodiment based on the above-provided frameless door detection tool further provides a frameless door detection method. In combination with Figures 3-6 , the detection method provided by the embodiment is specifically introduced.

[0044] The method comprises:

[0045] The frameless door detection tool is fixedly installed on the B pillar 100 of the vehicle to be detected,

[0046] The deviation between the outer surface 101 of the first door and the outer surface of the first profiling block 2 is measured, and the Y-direction deviation of the first door is judged;

[0047] The deviation between the second door outer surface 103 and the second profiling block 3 outer surface is measured to determine the second door Y-direction deviation;

[0048] The distance between the first door water-cut clamping surface 102 and the first profiling block 2 lower surface is measured to determine the first door Z-direction deviation;

[0049] The distance between the second door water-cut clamping surface 104 and the second profiling block 2 lower surface is measured to determine the second door Z-direction deviation.

[0050] After the front and rear doors are adjusted, the first and second positioning pins of the detection tool are respectively installed on the vehicle B-pillar trim panel positioning hole and the trim panel buckle installation hole when the front and rear doors are in the adjusted closed state, and the strong magnet is attracted to the vehicle B-pillar at this time to prevent the tool from falling. After the detection tool is installed, the step difference between the first profiling block outer surface and the front door (first door) outer surface is detected by using a measuring tool, and the relative position relationship between the first profiling block bottom surface and the front door water-cut clamping surface is detected, so as to detect the installation position state of the front door in the Y-direction and the Z-direction. In a possible implementation manner, the step difference between the first profiling block outer surface and the front door (first door) outer surface can be measured by using a flatness gauge or a step gauge; the relative position relationship between the first profiling block bottom surface and the front door water-cut clamping surface can be measured by using a triangular gap gauge or a plug gauge. Similarly, the step difference between the second profiling block outer surface and the rear door (second door) outer surface is detected by using a measuring tool, and the relative position relationship between the second profiling block bottom surface and the rear door water-cut clamping surface is detected, so as to detect the installation position state of the rear door in the Y-direction and the Z-direction. Thus, the secondary confirmation of the adjusted state of the frameless door in the welding workshop is realized, so as to maximize the matching quality of the frameless door glass system in the assembly workshop.

[0051] After the detection task is completed, if it is unqualified, the door needs to be adjusted again; if the Y-direction deviation and / or the Z-direction deviation of the first door does not meet the requirements, the first door is adjusted; if the Y-direction deviation and / or the Z-direction deviation of the second door does not meet the requirements, the second door is adjusted. If it is qualified, the detection tool is removed and placed in a designated position, and daily 5S management is done, waiting for the next detection work to be carried out.

[0052] The above only describes the preferred embodiments of the present disclosure and is not used to limit the present disclosure. For those skilled in the art, the present disclosure can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
