Automobile skylight opening detection tool and method for detecting skylight profile and gap by detection tool

Abstract

The invention provides an automobile skylight opening detection tool and a method for detecting a skylight profile and gap by the detection tool. The detection tool comprises a frame and a detection block, the detection block is connected with the frame through connection blocks, detection pins are arranged on the periphery of the frame and connected with the frame through the connection blocks, a plurality of positioning blocks are arranged on the periphery of the frame, connected with the frame through the connection blocks and used for axially and radially positioning automobile skylight plates, positioning compression mechanisms are arranged at two adjacent edges of the frame, and peripheral apexes of the frame are provided with reference blocks. The detection tool is placed at the corresponding position of an automobile skylight, a general rule detects whether a skylight opening gap is within a tolerance range or not, a segment difference rule detects whether a skylight opening profile is within a tolerance range or not, and the detection pins detect whether skylight mounting holes are within a tolerance range or not. The detection tool is closely matched with the automobile skylight, light in weight and firm, the detection method is simple to operate, and detection results are accurate.

Description

technical field [0001] The invention belongs to the field of automobile tooling inspection tools, and in particular relates to an automobile sunroof opening inspection tool and a method for detecting a sunroof profile and a gap by using the inspection tool. Background technique [0002] In the automobile manufacturing industry, cars with skylights are more and more favored by consumers because of their good ventilation and light. However, the sunroof is generally electrically controlled, and the sunroof is prone to wind and rain leakage, so the profile and clearance accuracy of the sunroof must meet the body design requirements. When the traditional inspection tool detects the surface and gap at the opening of the skylight, because the inspection tool and the skylight are not very closely matched, the detection result is not accurate, and the skylight that passes the inspection still has the situation of air leakage and rain leakage; and aluminum alloy is used It has the di...

AI Technical Summary

Problems solved by technology

However, the sunroof is generally controlled electrically, and the sunroof is easy to leak wind and rain, so the profile and clearance accuracy of the sunroof must meet the body design requirements

When the traditional inspection tool detects the surface and gap at the opening of the skylight, because the inspection tool and the skylight are not very closely matched, the detection result is not accurate, and the skylight that passes the inspection still has the situation of air leakage and rain leakage; and aluminum alloy is used It has the disadvantages of bulky, easy to deform, inconvenient operation, etc.
