Description

Technical Field

[0001] The utility model relates to the technical field of flatness detection, and more specifically to a flatness detection device for the side of a car sunroof. Background Art

[0002] The car sunroof is installed on the roof, which can effectively circulate the air in the car and increase the intake of fresh air. At the same time, the car sunroof can also broaden the field of vision and meet the needs of mobile photography and video shooting. Car sunroofs can be roughly divided into: sliding type, built-in type, built-in flip-out type, panoramic type and curtain type. When the car sunroof is produced, it is necessary to inspect the flatness of the sides around it to avoid installation difficulties or air leakage due to unevenness. For this purpose, a plane detection device is proposed to detect the side of the car sunroof.

[0003] After searching, for example, a Chinese patent application with publication number CN217005662U discloses a flatness detection device for the side of a car sunroof. The car sunroof is positioned and placed by using a placement groove, so that the side of the car sunroof close to the screw rod is tightly fitted with the inner wall of the placement groove, and then the electric push rod is driven to drive the pressure plate to fix the car sunroof to prevent the connection from loosening, which facilitates positioning and fixing, prevents the connection from loosening, and enhances the positioning and fixing effect; the drive motor is driven to drive the screw rod to rotate, the screw rod rotates to move the moving block, and drives the digital dial indicator to move, the pointer on the digital dial indicator moves along the side of the car sunroof, and by observing the digital dial indicator, the pointer on the digital dial indicator moves along the side of the car sunroof. The numerical value on the dial of the digital micrometer changes, so as to detect the flatness of the side of the car sunroof and judge whether the flatness of the side wall of the car sunroof is qualified, which plays a role in facilitating the detection of the flatness of the side wall of the car sunroof; by making the electric push rod work to drive the pressure plate to separate from the car sunroof and reach the avoidance position, and then making the cylinder work to drive the top plate to move, the top plate moves to push the car sunroof out of the base, which plays a role in facilitating the removal of the car sunroof; by making the screw rod parallel to the placement groove, when the side of the car sunroof is in contact with the side of the placement groove, the side of the car sunroof is made parallel to the screw rod, ensuring the accuracy of the moving block driving the digital micrometer to detect the side of the car sunroof along the screw rod.

[0004] However, when performing flatness detection in the above scheme, the car sunroof needs to be fixed and one side needs to be detected. Since the size of the placement groove is fixed, only sunroofs of fixed size can be detected during detection, and it is difficult to achieve car sunroofs of different fixed sizes. The effect is relatively simple, and when flatness calibration is performed using a digital micrometer, it is necessary to manually observe the changes in values ​​continuously, which is rather troublesome. It is difficult to mark the protruding or recessed positions, which delays the next step of modification work, and only one side of the sunroof can be detected. It is time-consuming to detect all around. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a flatness detection device for the side of a car sunroof.
