Description

Technical Field

[0001] The utility model relates to the technical field of glass testing, in particular to a testing tool for testing the matching flatness of a windshield and a vehicle body. Background Art

[0002] The windshield refers to the glass in front of the car cab that prevents air from entering the cab. However, during use, its position needs to be tested to prevent it from being installed unstable or irregularly and affecting its use.

[0003] The existing authorization announcement number is "CN103363878B", which is a gauge for detecting the flatness of the windshield and the vehicle body. It includes a gauge body and a detection blade. The detection blade is a plate-like structure. A group of detection blades of different heights are evenly distributed on the outer wall of the gauge body, and the bottom surface of a group of detection blades is on the same plane as the bottom surface of the gauge body. According to the inspection standard for the flatness of the windshield and the vehicle body of the vehicle, a detection blade of corresponding height is selected, and the gauge is placed on the plane of the vehicle body sheet metal and moved horizontally toward the edge of the windshield and contacted to observe whether the windshield is higher than the detection blade. It can quickly detect whether the flatness of the windshield and the vehicle body meets the requirements, reduce the inadequate assembly of the windshield, and improve the assembly quality. The gauge has a simple structure, is easy to operate, and has high detection efficiency.

[0004] However, when using the device, some positions need to be compared with the naked eye to test whether they are flat. Since the windshield is curved, some positions are close to the height of the detection device and are difficult to observe directly, thus affecting the subsequent use of the glass.

A connecting groove 73 is provided on one side of the side plate 6, a connecting rod 76 is provided on one side of the connecting groove 73, a bearing is provided on one side of the side plate 6, and the connecting rod 76 is located inside the bearing, so that the side plate 6 can rotate to prevent its rotation from being affected, a rotating plate 75 is provided on one side of the connecting rod 76, an internal threaded tube 71 is provided on one side of the rotating plate 75, a threaded rod 74 is provided inside the internal threaded tube 71, and a pressure plate 75 is provided on one side of the threaded rod 74 2. A through slot is provided at one end of the side plate 6, and the through slot is communicated with the connecting slot 73. One end of the rotating plate 75 extends to the outside of the side plate 6 through the through slot. After the rotating plate 75 extends to the outside, the staff can directly rotate the rotating plate 75 to adjust the position of the pressing plate 72. The top and bottom of the connecting slot 73 are symmetrically provided with limit slots. The top and bottom of the pressing plate 72 are symmetrically provided with slide plates, and the slide plates and the limit slots are adapted to each other to ensure that the pressing plate 72 can move in a straight line. During the test, the inspection fixture can be attached to the sheet metal of the vehicle body to ensure stability during the test.

[0022] Working principle: During the test, the inspection fixture is first placed on the windshield, while the side plate 6 is located on the sheet metal of the vehicle body. Then the rotating plate 75 is rotated so that the rotating plate 75 drives the threaded rod 74 to rotate. During the rotation of the threaded rod 74, the pressure plate 72 is displaced toward the outside of the side plate 6, so that the pressure plate 72 is attached to the angle between the windshield and the sheet metal, thereby preventing the inspection fixture from shifting during the movement. During the translation, the lower pressure plate 2 moves along the curvature of the windshield. If there is a deviation at one position, the height of the observation plate 4 at the deviation position is different from that of the observation plate 4 at other positions. Then, through the effect of comparison, even if the error is very small, it can be directly seen by observation, thereby improving the efficiency of the inspection.
