Description

Automobile windshield positioning tool

technical field

The invention belongs to the technical field of automobile installation equipment, and relates to an automobile windshield positioning tool.

Background technique

The automobile industry and the glass industry belong to two different industries. The former belongs to the machinery manufacturing industry, while the latter belongs to the light industry. However, judging from the development of automobiles, the relationship between the two is getting closer. Glass technology has completely penetrated into the automotive industry and has become an indispensable member of the automotive technology field. For example, the windshield of a car, after special treatment, can maintain a certain clarity of glass cracks when it is broken by impact , to ensure that the driver's field of vision is not affected. At present, car windshields are mainly made of laminated tempered glass and laminated tempered glass, which can withstand strong impact. The volume and weight of the windshield are large, and in order to ensure the airtightness inside the car, the edges and sides of the windshield need to be sealed and connected by sealing rubber. Glue is applied to the edge of the inner side, and then the sealing rubber is applied to the car body, and then the glue layer of the windshield is bonded to the sealing rubber. In the actual operation process, the windshield is lifted by two workers , and then lean against the window frame of the car body, it is more laborious to operate.
