Description

Technical Field

[0002] The main accessories involved in the installation of automotive door glass include brackets (for standard door glass) and sliders (for flush door glass). Installing brackets, sliders, and other accessories onto the glass is called the door glass assembly. The functional movement of the glass with these accessories installed is accomplished using tooling; this tooling is called the door glass accessory installation tooling. Both brackets and sliders in the door glass assembly have higher requirements for positional accuracy and fit. Because the dimensional tolerances and fit tolerances of the door glass assembly are affected by the dimensional tolerances and fit tolerances of the glass, brackets, and sliders, when any of these components experiences dimensional or temperature fluctuations, the cumulative tolerance exceeding the assembly tolerance will affect the quality of the assembly. Consequently, adjustments to the door glass accessory installation tooling are necessary.

However, the assembly product requires adjustments to other relative angles between the bracket and the glass, which cannot be achieved by existing installation fixtures for door and glass brackets.

[0039] Example 1 Please refer to Figures 1 to 5 An adjustable door glass bracket installation fixture, set on a workbench, is primarily used for precisely positioning and installing brackets on automotive door glass. This fixture mainly consists of the following parts: X-axis translation platform: Mounted on the worktable, allowing it to slide along the X-axis of the glass. One side of the platform has a flat surface that mates with the X-axis translation limit seat 11.

[0040] X-axis translation limit seat 11 and X-axis translation bolt 12: The X-axis translation limit seat 11 is fixed to the worktable by bolts. The X-axis translation bolt 12 passes through the bolt hole on the limit seat, and its end is threaded to the side of the X-axis translation platform. Several standard thickness shims 13 are provided between the contact surfaces of the X-axis translation platform and the X-axis translation limit seat 11. By adding or removing these shims 13 and tightening the X-axis translation bolt 12, the position of the X-axis translation platform in the X direction can be precisely set and locked.

[0041] X-axis rotation adjustment platform: This platform is used to achieve rotational adjustment around the X-axis and is directly fixed to the X-axis translation platform. It mainly includes: Moving track 21: Its bottom surface is fixed to the X-axis translation platform, and its upper surface is machined with a precision arc-shaped sliding surface. This moving track 21 is installed at a certain angle to the horizontal plane, making rotational adjustments more ergonomic. Angle graduations are engraved on the side of the track.

[0042] Movable component 22: Its bottom has a structure that matches the arc-shaped sliding surface of the moving track 21, allowing it to slide along the track and thus achieve rotational movement around the X-axis. An indicator button 25 is mounted on the movable component 22 to point to the angle scale on the moving track 21.

[0043] Lead screw 23: serves as a rotary drive mechanism. Its fixed end is rotatably connected to one end of the moving track 21 via a bearing or an annular groove, and its movable end is threadedly connected to the moving part 22. Rotating the lead screw 23 precisely drives the moving part 22 to slide along the arc-shaped track.

[0044] Locking bolt 24: Located on the moving part 22. After the rotation angle is adjusted to the correct position, tightening the locking bolt 24 will cause its front end to press against the moving track 21, firmly locking the moving part 22 and preventing changes in angle during processing.

[0045] Y-axis translation platform 3: This platform is used to achieve translational movement along the Y-axis direction, and it is mounted on the X-axis rotation adjustment platform via the moving part 22. It mainly includes: Fixed base 31: It consists of a base plate 311 and a first slide cylinder 312 fixed thereon by bolts.

[0046] Sliding component 32 mainly consists of a second slide cylinder 321 and a bracket clamping cylinder 322. The second slide cylinder 321 is fixedly mounted on the slider of the first slide cylinder 312. The bracket groove 4 is fixedly mounted on the end of the slider of the first slide cylinder 312 and is used to support and initially position the bracket. The bracket clamping cylinder 322 is mounted on the slider of the second slide cylinder 321.

[0047] Y-axis limiting seat 313 and Y-axis limiting bolt 314: The Y-axis limiting seat 313 is fixed to the base plate 311. The Y-axis limiting bolt 314 passes through the bolt hole on the limiting seat, and its end can abut against the side of the slider of the first slide cylinder 312. By adjusting the insertion length of the Y-axis limiting bolt 314, the extension stroke of the first slide cylinder 312 can be precisely controlled by mechanical limiting, thereby setting the final installation position of the bracket in the Y-axis direction.

[0048] The working principle and usage of the aforementioned adjustable door glass bracket installation fixture: The core function of this fixture is to achieve fine adjustment of the bracket in three degrees of freedom: translation in the X and Y directions and rotation around the X-axis. Its usage process is as follows: Step 1: Initial positioning and bracket clamping The car glass is secured in the correct position on the worktable using a specialized glass positioning and clamping device. The operator then places the bracket to be installed into bracket slot 4.

[0049] Step 2: Perform translation adjustment along the X-axis. If the inspection tool detects a deviation in the bracket's position along the X-axis of the glass, this adjustment is performed. Loosen the X-axis translation bolt 12, and change the overall thickness of the shims 13 group by adding or removing shims 13 between the X-axis translation platform and the X-axis translation limit seat 11, thereby slightly moving the X-axis translation platform and all its components. After adjusting to the target position, tighten the X-axis translation bolt 12 to lock it in place.

[0050] Step 3: Adjust the rotation angle around the X-axis If the inspection tool detects an angular deviation (pitch angle) between the bracket and the glass around the X-axis, this adjustment is performed. Loosen the locking bolt 24, and then rotate the lead screw 23. The lead screw 23 drives the moving part 22 to slide the entire Y-axis translation platform 3 along the arc surface of the moving track 21, thereby achieving rotation around the X-axis. By observing the position of the indicator button 25 on the moving part 22 relative to the angle scale on the moving track 21, the desired angle can be precisely adjusted. After adjustment, immediately tighten the locking bolt 24 to fix the angle.

[0051] Step 4: Perform Y-axis translation adjustment If the inspection tool detects a deviation in the position of the bracket in the Y-axis direction (length direction) of the glass, this adjustment is made. This adjustment is achieved by controlling the stroke of the first slide cylinder 312, rotating the Y-axis limit bolt 314, adjusting the distance between the final position of the sliding member 32 and the Y-axis limit bolt 314, thereby controlling the final installation position of the bracket in the Y-axis direction.

[0052] Step 5: Perform the installation work After all adjustments are completed and locked, installation can proceed. The first slide cylinder 312 is activated, pushing the slide 32, bracket groove 4 and bracket together to move towards the glass until they are blocked by the Y-axis limit bolt 314. At this time, the bracket is sent to the predetermined installation point on the glass surface.

[0053] In conclusion, the aforementioned adjustable door and glass bracket installation fixture enables multi-directional adjustment of the bracket. It can flexibly adjust the relative angle between the bracket and the glass according to the dimensional tolerances and fit fluctuations of the glass, bracket, and the bracket, thus ensuring the quality of the door and glass assembly.
