Window cutting device

Abstract

The invention provides a window cutting device. The window cutting device comprises a cutting gun clamping assembly and an explorator abutting against the surface of an object to be cut. The explorator is provided with an open hole corresponding to a window to be cut in size. The cutting gun clamping assembly comprises a base, vertical guide wheels, transverse guide wheels and a fixing sleeve; the vertical guide wheels are rotationally arranged on the base; the rotating center lines of the vertical guide wheels are parallel to the upper surface, deviating from the cut object, in the explorator, and the rims of the vertical guide wheels make contact with the upper surface; the transverse guide wheels are rotationally arranged on the base; the rotating center lines of the transverse guide wheels are perpendicular to the upper surface, deviating from the cut object, of the explorator, and the rims of the vertical guide wheels make contact with the side wall of the open hole; the fixing sleeve is arranged on the base; and the fixing sleeve is provided with a through hole for allowing the cutting gun to penetrate through. According to the window cutting device, the cutting precision can be improved.

Description

technical field [0001] The present application relates to rail vehicle window cutting technology, in particular to a window cutting device. Background technique [0002] Rail vehicles are an important transportation link connecting cities, and have gradually become the main means of transportation in cities. The side wall of the rail vehicle is provided with a window, and the window is installed at the window. The side wall is usually composed of a side wall frame and a stainless steel outer skin. After the outer skin and the side wall frame are assembled, the side wall is cut to form a window. The traditional cutting method is: manually drill three 5mm positioning holes at each window position of the side wall, then turn over the side wall for formal installation, use the window cutting template to position through the positioning holes, and then manually cut the window with a cutting device, cut A margin of 3mm is reserved for the size, and finally it is manually ground ...

AI Technical Summary

Problems solved by technology

[0003] The above solution requires reverse drilling and front cutting of the side wall. Due to the difficulty of stainless steel drilling, the hole position is easy to shift, resulting in low positioning accuracy, which in turn leads to large deviations in window cutting

Moreover, due to the large volume of the side wall, it is not easy to turn over the operation, which is time-consuming and labor-intensive, and there are certain safety risks

In addition, when plasma cutting the window, the hand-held cutting gun slides on the inside of the formal cutting template for cutting. Since the angle of the cutting gun is difficult to control, the size of the cut window is not accurate, and manual grinding is required, which is inefficient; During the cutting process, due to the release of stress, the cutting gun and the side wall surface are prone to sudden jumps, and it is very easy to cause window overcutting. Once the outer skin is damaged, it cannot be repaired
