Device for bonding, curing, and pressing side window glass of metrovehicle

Abstract

The invention discloses a device for bonding, curing and pressing side window glass of a metrovehicle. The device comprises a connection rod, a hanging device, a pressing device and a fastening device; the hanging device is arranged at the upper end of the connection rod; the pressing device is arranged at the position of the connection rod which is adaptive to the height of the side window glass; and the fastening device is arranged at the lower end of the connection rod. The device has a simple structure and is easy to operate; a plurality of fastening devices can be reasonably arranged according to the position of the glass to ensure that the stress point of the glass is at the optimal position; the pressing force of each pressing device can be controlled independently, and the corresponding torsion equipment ensures the same stress of each stress point; the direction of the pressing force is vertical to the glass plane, so that the stress in other directions is avoided, the effective solidification of bonding glue is ensured, the bonding intensity is ensured, the glass is flushed with a vehicle body after being bonded, and is attractive; and when fixed with the side of the metrovehicle, the device is firm and reliable; and the device has light weight and high rigidity.

Description

technical field [0001] The invention relates to a mechanical clamping device, in particular to a device for position fixing and clamping of the upper side window glass of a subway vehicle during the bonding and curing stage. Background technique [0002] In order to meet the sufficient vision and aesthetic requirements of subway vehicles, the side windows usually use a large area of ​​tempered glass, and the connection between the glass and the car body is mainly based on bonding. The currently used glue requires a curing time of 72 hours after bonding, and the glass must be in a compact state during the curing time. In order to ensure tightness, a tension belt device was used in the past. The tension belt is composed of upper and lower hooks, a nylon strap and a tension device. Use the upper and lower hooks to hook the upper and lower edges of the car body, operate and adjust the tensioning device to gradually tighten the nylon belt, and compress the foam between the nylo...

Problems solved by technology

[0003] Although this kind of device has the effect of compaction, there are several problems as follows: the stress points of the glass are unevenly distributed, and since the position of the compaction foam is placed manually, it is difficult to ensure the reasonable distribution of the compaction points on a piece of glass. , so it is easy to cause errors in the position distribution of each pressing point of the glass when several tensioning bands are used on the same piece of glass, which makes the load distribution stress uneven, which easily causes warping of the glass and affects the bonding force and air tightness, so that the adhesion between the glass and the car body cannot meet the standard requirements, and it affects the appearance of the subway car; there is a component force on the glass in the direction of the force, because the tensioning principle of the tensioning device is to shrink the nylon belt, so the glass in the The vertical pressure is also subjected to the component force of the tension direction, causing the glue to generate shear stress. When multiple tension forces are applied at the same time, due to the uneven tension force, the magnitude of the shear stress is also different, which is easy to cause glue The tearing of the window or the plane distortion of the window; because the nylon belt is a flexible body, it is very common to swing during installation and disassembly. destroy
