Cabin door guide device of air tightness detection cabin

Abstract

The invention relates to the field of the air tightness detection device of laser cutting equipment, in particular to a cabin door guide device of an airtight detection cabin. A portal frame comprisesa first stand column, a second stand column, an upper cross beam and a lower cross beam, the cabin door guide device comprises an upper sliding rail and a lower sliding groove, wherein the upper sliding rail is arranged under the upper cross beam, and the lower sliding groove is formed in the lower cross beam, and the cabin door is arranged between the upper cross beam and the lower cross beam ina vertical posture. The device is used for quickly moving a heavy cabin door, and the whole vertically-placed cabin door is well fixed through the upper sliding rail and the lower sliding groove, andthe guide is flexible, so that the deformation of the upper sliding rail caused by the dead weight of the cabin door to the rail can be effectively avoided, and the technical problem that the cabin door cannot be normally moved or even cannot be normally closed due to rail deformation after long-term use is avoided; the cabin door adopts a translation starting mode, the occupied space is small, and the defect that the occupied space of the rotary opening of the cabin door is large due to the fact that the cabin door is connected with the cabin body in a traditional hinging way is overcome.

Description

technical field [0001] The invention relates to the field of airtightness testing equipment for laser cutting equipment, in particular to a door guide device for an airtightness testing cabin. Background technique [0002] Laser cutting equipment needs to be checked for air tightness during the manufacturing process. The corresponding hatch door is relatively bulky, and the opening and closing of the hatch door is often time-consuming and laborious. In actual production operations, the hatch door is usually connected to the cabin body in a hinged manner, and the hatch door must rotate around a fixed axis when hinged. Open or close, resulting in the opening and closing of the hatch requires a certain amount of space. However, there is often not enough space for the hatch to open at the production site, and the heavy hatch is connected to the cabin by hinges. Deformation occurs at the hinge, which affects the airtightness of the door when it is closed. Therefore, it is necess...

Problems solved by technology

The corresponding hatch door is relatively bulky, and the opening and closing of the hatch door is often time-consuming and laborious. In actual production operations, the hatch door is usually connected to the cabin body in a hinged manner, and the hatch door must rotate around a fixed axis when hinged. Open or close, resulting in the opening and closing of the hatch requires a certain amount of space. However, there is often not enough space for the hatch to open at the production site, and the heavy hatch is connected to the cabin by hinges. Deformation occurs at the hinge, which affects the airtightness of the door when it is closed. Therefore, it is necessary to make technical improvements to the opening method of the door to ensure that the airtightness is still good after the door is opened and closed for a long time, and as much as possible Reduce the space required to open the hatch
