Problems solved by technology

The windshield is installed on the upper side of the sheet metal edge. In bad road conditions, if the sheet metal edge is in contact with the windshield, it is very likely that the windshield will explode due to mutual extrusion between the edge and the windshield.
However, due to the irregular bonding surface of the sheet metal flange and the windshield glass, there is no special tool for measuring the height of the flange in the prior art. At present, the height of the flange can only be measured with the three-dimensional coordinates of the vehicle, but the cycle of measurement time is relatively long. It is long and cumbersome to operate, and at the same time, timely and effective online monitoring cannot be carried out

Embodiment Construction

[0008] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0009] Such as Figure 1~5 As shown, the tool 10 is provided with a positioning reference plane 11, and the slope of the positioning reference plane 11 coincides with the slope of the plane 20 of the sheet metal where the tooth edge 21 is located.

[0010] As a preferred version of the present invention, such as figure 1 As shown, the tool 10 is provided with an end surface 13 on the side of the positioning reference surface 11 facing the windshield, and the end surface 13 is provided with a scale line for measuring the height of the tooth edge 21 .

[0011] The end face 13 can be an inclined plane or a vertical plane. When the scale line is set on the end face 13, if the installation height of the windshield glass is marked at the same time, then when the end face 13 is close to the sheet metal edge 21, not only the topmost distance between the end face 1...

Abstract

The invention belongs to the technical field of measurement and specifically relates to a tool for measuring the height of a sheet metal tooth edge arranged at an automobile windshield. A positioningreference surface is arranged on the tool, and the gradient of the positioning reference surface is coincided with that of a plane of a sheet metal located by the tooth edge. When the tool is used formeasurement, the positioning reference surface leans against the measurement position of the plane of the sheet metal, as the gradient of the positioning reference surface is coincided with that of the plane of the sheet metal, the positioning reference surface can closely lean on the plane of the sheet metal; meanwhile, one end of the tool is near to the sheet metal tooth edge, the height difference between the end part of the tooth edge and the top end of the sheet metal tooth edge which are near to the tool is measured by visual measurement or adopting a ruler, thereby effectively controlling the distance between the windshield and the sheet metal tooth edge and having the advantages of convenient and fast measurement, good measurement effect and low measurement cost.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a tool for measuring the height of a sheet metal edge at an automobile windshield. Background technique [0002] Generally speaking, the cause of the self-explosion of the front and rear windshields of the car is closely related to the height of the tooth edges pasted on the sheet metal. The windshield is installed on the upper side of the sheet metal edge. In bad road conditions, if the sheet metal edge is in contact with the windshield, it is very likely that the windshield will explode due to mutual extrusion between the edge and the windshield. However, due to the irregular bonding surface of the sheet metal flange and the windshield glass, there is no special tool for measuring the height of the flange in the prior art. At present, the height of the flange can only be measured with the three-dimensional coordinates of the vehicle, but the cycle of measurement...
