Problems solved by technology
[0002] When producing side door frames of road rollers, especially when producing side door frames of road rollers in large quantities, it is difficult to solve the problem of positioning and installation. Due to the large volume and weight of the workpiece, the dimensional accuracy is high, and it is difficult to guarantee the product during welding and assembly. The line size between each part, such as the parallelism, perpendicularity, coaxiality of the workpiece, etc., is easy to be deformed by welding
In general, during production, only the parallelism of the line can be drawn manually, and the square measure the verticality. When assembling the workpiece, the drawn line needs to be aligned, and the two ends of the workpiece need to be stabilized and fixed by hand. Its welding quality is difficult to guarantee, and the work efficiency is low, it is difficult to meet the needs of mass production

Embodiment Construction
[0021] In order to make the present invention more comprehensible, a preferred embodiment is described in detail below with accompanying drawings.
[0022] figure 1 A schematic diagram of a positioning welding structure of a side door frame of a road roller provided by the present invention, the method of positioning welding of a side door frame of a road roller includes the following 8 steps:
[0023] Step 1: Combine image 3 , the hinge 15 is positioned on a corner of the base 7 by the hinge positioning device 6 . The hinge positioning device 6 is composed of mutually matched bearings and pin shafts, and the holes of the hinge are positioned through the positioning pins of the hinge positioning device.
[0024] Step 2: Position one end of the first square steel 11 through the first positioning block 1, combine figure 2 , clamp the first square steel with the clamping device 5, and the other end of the first square steel 11 is firmly spot-welded with the hinge 15.

The invention provides a method for positioning and welding a roller side door frame. The method is characterized by comprising the following steps of: positioning a hinge on a corner of the base through a hinge positioning device, positioning each piece of square steel through a positioning block, clamping the square steel by using a clamping device, and fixedly welding the square steel. According to the method, the defects in the prior art are overcome, and the method is convenient in positioning and mounting, high in welding quality and high in working efficiency.
Description
technical field [0001] The invention relates to a positioning welding method for a side door frame of a road roller, belonging to the technical field of road rollers. Background technique [0002] When producing side door frames of road rollers, especially when producing side door frames of road rollers in large quantities, it is difficult to solve the problem of positioning and installation. Due to the large volume and weight of the workpiece, the dimensional accuracy is high, and it is difficult to guarantee the product during welding and assembly. The row size between the parts, such as the parallelism, perpendicularity, and coaxiality of the workpiece, is easy to be deformed by welding. Under normal circumstances, during production, only the parallelism of the line can be drawn manually, and the square is used to measure the verticality. When assembling the workpiece, it must be aligned with the drawn line, and the two ends of the workpiece need to be stabilized and fixe...
