Installing and welding tool for cab

Abstract

The invention relates to an installing and welding tool for a cab, which comprises a baseplate, a three-direction pressing and positioning device arranged on the baseplate, a large-floor middle pressing device, a crash barrier positioning and pressing device, a left pressing device, a right pressing device, a camber beam positioning and pressing device, a doorframe pressing device, a cross beam positioning and pressing device and an end chuck positioning block, wherein the large-floor middle pressing device, the crash barrier positioning and pressing device, the left pressing device and the right pressing device are arranged on one side of the three-direction pressing and positioning device, the camber beam positioning and pressing device, the doorframe pressing device, the cross beam positioning and pressing device and the end chuck positioning block are arranged on the other side of the three-direction pressing and positioning device, the left pressing device and the right pressing device are respectively arranged on two ends of the three-direction pressing and positioning device, the large-floor middle pressing device is arranged between the left pressing device and the right pressing device, one end of the large-floor middle pressing device is further provided with a large-floor rear positioning device, and the two ends of the three-direction pressing and positioning device are provided with pressing and positioning mechanisms. By means of the invention, the vertical dimensions of end parts of a cross beam and a camber beam are ensured, the cross beam is prevented fromlateral bending, and the installing and welding tool has the advantages of convenience for operation and bodilessness, good generality and capability of clamping manually and is convenient, flexible and reliable to mount and dismount.

Description

technical field [0001] The invention relates to a welding tool, in particular to a driver's cab assembly welding tool, which belongs to the technical field of welding devices. Background technique [0002] In the welding process of the driver's cab of the railway vehicle, it is currently used to perform tack welding first, and then perform full welding. Spot welding is used to position parts. In the past, the manual butt joint method was used. This method has a great impact on the deformation of the driver's cab during full welding, affects the welding quality, and causes the potential danger of vehicle accidents, and the production efficiency is low and the operation is inconvenient. Contents of the invention [0003] In order to overcome the defects in the prior art, the purpose of the present invention is to provide a driver's cab welding tool that can adjust the positioning according to the degree of welding deformation of the product. It is manually clamped, easy to ...
