[0049] Specific embodiments:

[0050] This frameless door glass positioning and adjustment tool uses four main frames 1 as calibration frames, corresponding to the left front, right front, left rear, and right rear doors respectively. Moreover, the left front and right front, as well as the left rear and right rear, are symmetrically arranged. The main frame 1, positioning pins, positioning blocks, and clamping devices are integrated into a whole to simulate the relative spatial dimensions of the door and the door glass. Among them, the positioning pins and positioning blocks are installed on the frame through bolts, and the installation points have a certain adjustment margin, which is convenient for the subsequent follow-up adjustment of the positioning points of the positioning and adjustment tool according to the accuracy optimization of the body in white. The calibration frame can effectively solve the positioning problem of the door glass of the frameless door and ensure that the glass gap surface difference is qualified after the door assembly is installed on the whole vehicle;

[0051] On the upper frame of the main frame 1, a door glass positioning block 4 and a glass clamping device 5 used in cooperation with it are installed. On the lower frame of the main frame 1, a door positioning block 6 and a door positioning pin 7 are installed, which are used to position the door sheet metal, and cooperate with a door clamping device 8 to clamp the sheet metal and fix the door at the lower part of the main frame 1. At the top of the main frame 1, there is a lifting ring 3 for suspension.

[0052] Specifically, the positioning and adjustment tool installs lifting rings 3 at the top of the upper frame of the main frame 1, and uses a spring balancer to suspend the positioning and adjustment tool on the C-shaped track. There are two lifting rings 3 on one main frame 1, which is convenient to ensure the balance on the X-Z plane. The two Y-direction lifting rings 3 are arranged on the gravity plane of the main frame 1 to ensure the balance on the Y-Z plane. Through the arrangement position of the lifting rings 3, it is ensured that the posture of the whole main frame 1 is in the door design posture after being lifted, which is convenient for the positioning of the door and the door glass;

[0053] The positioning and adjustment tool is designed according to the developed space dimensions of the frameless door assembly (with door glass). The main frame 1 of the positioning and adjustment tool is divided into upper and lower parts. The upper frame is used for positioning the door glass, and the lower frame is used for positioning the door body;

[0054] Two door positioning pins 7 are installed on the lower frame of the main frame 1. The door positioning pins 7 are made of nylon, which is light and does not damage the sheet metal. By means of the positioning holes on the inner sheet metal of the door, the X-direction, Z-direction, and Y-axis rotation degrees of freedom of the door are restricted. Six door positioning blocks 6 are also installed at the top of the lower side of the main frame 1 to support the sheet metal. They are made of nylon, with light quality and no damage to the sheet metal. The positioning pins and positioning blocks cooperate to support on the inner sheet metal surface of the door, restricting the Y-direction, Z-axis rotation, and X-axis rotation degrees of freedom of the door. The whole vehicle positioning module can completely restrict the 6 degrees of freedom of the door. Four clamping devices are installed at the edge position of the lower frame of the main frame 1, which can clamp the door and the positioning and adjustment tool to ensure more controllable positioning;

[0055] Twelve glass positioning blocks 4 are installed on the upper frame of the main frame 1. The glass positioning blocks 4 are made of nylon, which is lightweight and does not damage the glass. Among them, at the corresponding positions, seven glass positioning blocks 4 are used to provide positioning for the door glass surface, which can limit the degrees of freedom of the Y-direction, Z-axis rotation, and X-axis rotation of the door glass. Five glass positioning blocks 4 are used for side positioning of the door glass, which can limit the degrees of freedom of the X-direction, Z-direction, and Y-axis rotation of the door glass. Thus, the six degrees of freedom of the door glass can be completely limited by the twelve glass positioning blocks 4;

[0056] Five glass clamps 5 are installed at the edge position of the upper frame of the main frame 1, which can clamp the door glass and the positioning and adjustment device to ensure more controllable positioning;

[0057] Among them, a glass lifting device 2 for lifting the door glass is fixedly connected to the middle of the lower frame of the main frame 1. The top of the glass lifting device 2 contacts the bottom edge of the glass through a glass support seat 22. One side of the glass lifting device 2 is provided with a guide rail 22 and a limit stop 24. The limit stop 24 has several positioning slots along the length direction of the guide rail 22. Among them, the guide rail 22 is slidably connected to the glass support seat 22. The glass lifting device 2 is in screw drive with the glass support seat 22 through a screw drive mechanism. An external handle 23 for driving its lifting is connected to the glass support seat 22. The handle 23 is rotatably connected with a connecting rod, and the position of the glass support seat 22 is locked by engaging with the positioning slots at different positions of the limit stop 24 through the connecting rod. During use, the door glass is lifted to the highest point by moving the glass lifting device 2 up and down, ensuring that the glass is closely attached to the top glass positioning block 4 in the Z-direction. During use, first, the positioning and adjustment device is assembled and clamped with the door. Then, the door glass is lifted to the highest point by using the glass lifting device 2 so that it contacts the Z-direction glass positioning block 4. Then, the door glass is clamped on the positioning and adjustment device by using the glass clamp 5, and the door glass is positioned on the device. Thus, the spatial dimensions of the door glass reach the design standard through the positioning and adjustment device. Then, the installation bolts of the door glass are tightened. At this time, the installation dimensions of the door glass on the door can meet the design requirements.

[0058] In the above technical solution, a method for using a frameless door glass positioning and adjustment device provided by the present utility model is as follows:

[0059] Step 1: The operator grabs the main frame 1 of the positioning and adjustment device by hand and adjusts the posture of the positioning and adjustment device to ensure that the positioning surface of the door positioning block 6 on the main frame 1 is parallel to the door sheet metal;

[0060] Step 2: Slowly translate the positioning and adjustment device along the Y-direction, align the door positioning pin 7 on the positioning and adjustment device with the positioning hole on the door sheet metal, slowly insert the door positioning pin 7 on the positioning and adjustment device into the corresponding positioning hole on the door, and continue to translate the positioning and adjustment device along the positioning hole to make the door positioning block 6 on the positioning and adjustment device fit the inner door sheet metal;

[0061] Step 3: Clamp the car door with the car door clamp 8 on the lower frame of the main frame 1 of the positioning and adjustment tool.

[0062] Step 4: Use the glass lifting device 2 to lift the car door glass to the uppermost side. After lifting it to the uppermost side, rotate the handle on the glass lifting device 2 and lock the connecting rod on the handle 23 into the positioning groove of the limit stop 24 of the glass lifting device 2 to ensure that the upper side of the car door glass is always in contact with the car door glass positioning block 4.

[0063] Step 5: Clamp the car door glass with the glass clamp 5 on the upper frame of the main frame 1 of the positioning and adjustment tool to ensure that the car door glass surface is in contact with the car door glass positioning block 4.

[0064] Step 6: Use a torque wrench to install and tighten the car door glass mounting bolts.

[0065] Step 7: Rotate the handle 23 of the glass lifting device 2 to push the connecting rod out of the positioning groove, lower the glass lifting device 2 to the lowest position, remove the glass clamp 5 on the upper frame of the main frame 1 of the positioning and adjustment tool and the car door clamp 8 on the lower frame of the main frame 1 of the positioning and adjustment tool, slowly move it in the Y direction, remove the positioning and adjustment tool, and place the positioning and adjustment tool at the line side position to complete the assembly of one car door and glass.

[0066] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
