The glass x-axis linkage device includes a first support plate, a second support plate, a connecting plate, and an x-axis sliding assembly; the connecting plate is movably connected to the second base plate through the x-axis sliding assembly, thereby enabling the connecting plate to move along the x-axis; the first support plate and the second support plate are respectively disposed on the connecting plate, the first support plate is connected to the glass x-axis positioning block, and the second support plate is connected to the glass x-axis positioning reference; The glass y-axis positioning device includes at least three glass y-axis positioning blocks discretely distributed on the second base plate; The door positioning device includes at least two discretely distributed door x / z-direction positioning pins and at least three door y-direction positioning devices; The door clamping device includes a door clamping cylinder and a door clamp; the door clamping cylinder is mounted on the first base plate, and the telescopic rod of the door clamping cylinder is connected to the door clamp, which is used to drive the door clamp to move along the y-direction to cooperate with the door y-direction positioning device to clamp the door.

2. The positioning fixture for adjusting frameless car door glass as described in claim 1, characterized in that, The x-axis sliding assembly includes an x-axis linkage cylinder. The telescopic rod of the x-axis linkage cylinder is connected to the connecting plate and is used to drive the connecting plate to move along the x-axis. The x-axis linkage cylinder is also fixed to the second base plate.

3. The positioning fixture for adjusting frameless car door glass as described in claim 2, characterized in that, The x-axis sliding assembly also includes a guide rail and a slider. The guide rail is fixedly mounted on the second base plate along the x-axis, and the slider moves and cooperates with the guide rail along the x-axis. The slider is also fixedly connected to the connecting plate.

4. The positioning fixture for adjusting frameless car door glass as described in claim 1, characterized in that, The glass z-axis positioning device includes at least two glass z-axis positioning blocks.

5. A positioning fixture for adjusting frameless car door glass as described in claim 1, characterized in that, The glass positioning fixture also includes a power suction cup, which is disposed on the second base plate, and the glass z-axis positioning device and the glass y-axis positioning device are distributed around the power suction cup.

6. A positioning method for adjusting frameless car door glass, based on the positioning fixture for adjusting frameless car door glass as described in any one of claims 1-5, characterized in that, Includes the following steps: The door positioning device of the door positioning fixture abuts against the inner panel of the door, and the door clamping device of the door positioning fixture clamps the door positioning fixture to the door. The glass x-axis positioning reference of the glass x-axis positioning component of the glass positioning fixture is abutted against the outer panel of the car door. With the outer panel of the car door as the reference, the position of the glass x-axis positioning block is adjusted by the glass x-axis linkage device, so that the glass x-axis positioning block moves along the x-axis to the glass x-axis positioning point. Adjust the glass along the x-axis so that the side end of the glass abuts against the glass x-axis positioning block; Adjust the glass along the z-axis so that the upper end of the glass abuts against the glass z-axis positioning device; Lock the glass to the glass bracket on the car door; Adjust the glass along the y-axis so that the end face of the glass abuts against the glass y-axis positioning device.
