Description

Technical Field

[0001] The present invention relates to the technical field of automobile manufacturing testing, and particularly relates to a frameless door height detection device and a detection method thereof. Background Art

[0002] With the development of the automobile industry and the trend of styling changes, in the future, more and more vehicle models will abandon traditional full-frame doors or semi-frame doors and choose frameless doors with lighter weight and more novel styling.

[0003] Traditional full-frame doors and semi-frame doors have sheet metal in the window frame glass area, and the Z-direction distance between the upper part and the side panel is relatively small (generally 3-5 mm for full-frame doors according to the design, and generally 5-15 mm for semi-frame doors according to the design). In production, conventional measuring tools (such as French wheels and triangular rulers, etc.) can be used to easily detect and control the Z-direction height of these two types of doors; or the height of the door can be determined by controlling the Z-direction gap between the lower part of the door and the side panel.

[0004] However, the entire window frame area of the frameless door has no sheet metal, and the Z-direction distance from the upper side panel is very large. For example, in a certain frameless door model of the applicant, there is a trim panel in the side panel part, resulting in the inability to determine the height of the door through the Z-direction gap between the lower part of the door and the side panel on the white body. Therefore, the Z-direction height control of the frameless door cannot be completed by conventional tools at the production site, and a new detection control system is required to complete the Z-direction control of the frameless door.

[0005] At the same time, compared with conventional framed doors, the insertion amount of the frameless door glass is also one of the evaluations, which has an impact on both matching and functionality, and the Z-direction of the door has a great influence on the position height of the glass.

[0006] According to the design and matching rules of the automobile, the Z-direction at the rear of the rear door can generally be controlled through the relative relationship with the side panel. Mainly, new tooling is required to control the height position of the frameless door in the B-pillar and A-pillar areas. Summary of the Invention

[0007] In view of the above problems in the prior art, the present invention proposes a frameless door height detection device and a detection method thereof, which can determine the installation height of the frameless door, adjust the height of the frameless door according to the assembly requirements, and effectively reduce the assembly defects of the frameless door.

[0075] Figure 5 The flowchart of the frameless door height detection method according to an embodiment of the present invention is shown. As shown in the figure, the present invention also provides a frameless door height detection method, which is applicable to the aforementioned frameless door height detection device. The detection method includes the following steps:

[0076] S1. Determine three measurement points 108 at the front end of the top, the rear end of the top of the frameless front door 120 assembled on one side of the body-in-white 101, and the front end of the top of the frameless rear door 121. These measurement points 108 serve as the benchmarks for the installation height of the frameless door.

[0077] S2. Fix the first detection component 102 to the A-pillar area 107 of the body-in-white 101. The positioning pin 106 is inserted into the main positioning hole of the A-pillar area 107.

[0078] S3. Obtain the height of the measurement point 108 at the front end of the top of the frameless front door 120 through the first detection component 102, and obtain the height of the measurement point 108 at the rear end of the top of the frameless front door 120 and the height of the measurement point 108 at the front end of the top of the frameless rear door 121 through the second detection component 103.

[0079] S4. Compare the height information of the three measurement points 108 with the set conditions. If it meets the set conditions, the installation height of the frameless door meets the requirements, and proceed to step S5. If it does not meet the set conditions, adjust the installation heights of the frameless front door 120 and the frameless rear door 121, and proceed to step S3, where the set conditions are the set height ranges of the respective measurement points 108.

[0080] S5. End.

[0081] For the frameless door height detection method provided by the present invention, the height position information of the measurement point 108 can be quickly obtained through the first detection component 102 and the second detection component 103. By adjusting the heights of the frameless front door 120 and / or the frameless rear door 121 to meet the set height range, the qualified rate of the frameless door assembly is effectively improved.

[0082] Preferably, after performing step S1 and before performing step S2, install the frameless front door 120 and the frameless rear door 121 on the body-in-white 101; or after performing step S2 and before performing step S3, install the frameless front door 120 and the frameless rear door 121 on the body-in-white 101. In other words, the installation of the frameless door can be completed before or after installing the frameless door height detection device, and adjusting the installation height of the frameless door does not require adjusting the position of the frameless door height detection device.

[0083] Preferably, in step S2, the second tooling body 109 is fixed to the B-pillar 115 of the white body 101 by the clamping mechanism 110. Generally, the second tooling body 109 fits against the B-pillar 115 of the white body 101 by its own weight. The first positioning block 111 is abutted against one side of the B-pillar 115, and the second positioning block 112 is lapped on the top of the B-pillar 115 to complete the X / Y / Z-axis positioning of the second tooling body 109, that is, to position the first measuring block 113 and the second measuring block 114. Usually, a distance of about 5 mm is reserved between the first measuring block 113 and the second measuring block 114 and their respective corresponding measuring points 108. Finally, the chuck of the clamping mechanism 110 is clamped to the B-pillar 115 to complete the installation of the second detection assembly 103.

[0084] Preferably, the height measuring device 105 includes a display part 117 and a measuring rod 118. The measuring rod 118 penetrates into the display part 117 and can be slidably matched with the display part 117. The display part 117 is used to obtain and display the position height of the bottom end of the measuring rod 118. In step S3, the measuring rod 118 is pushed downward so that the bottom end of the measuring rod 118 contacts the measuring point 108 at the front end of the top of the frameless front door 120, and the height value displayed by the display part 117 is obtained. Then, a feeler gauge is inserted between the first measuring block 113 and the measuring point 108 at the rear end of the top of the frameless front door 120, and the corresponding height value of the feeler gauge is read. The feeler gauge is inserted between the second measuring block 114 and the measuring point 108 at the front end of the top of the frameless rear door 121, and the corresponding height value of the feeler gauge is read, so as to complete the height measurement of the three measuring points 108.
