Description

Loader sub vehicle frame processing frock Technical Field The invention relates to the technical field of auxiliary frame processing, in particular to a loader auxiliary frame processing tool. Background The auxiliary frame of the wheel loader is also called a swing frame and is used as a key bearing part of the whole machine and used for connecting a rear frame and a rear drive axle, and a box type or frame structure formed by welding steel plates is adopted. The auxiliary frame is mainly formed by combining two cross beams and two side beams with sleeve grooves, and the cross beams and the side beams can be connected in a lap joint or plug welding mode. For the auxiliary frame under heavy working conditions, the auxiliary frame is usually subjected to splicing welding by means of a special processing tool, and working procedures such as blank cutting and polishing are matched, so that the integral strength and the use reliability of the structure are effectively improved. When the existing heavy auxiliary frame processing tool is used for carrying out combined positioning processing on the cross beam and the side beam, a cross beam and side beam positioning die with compact inner space is generally adopted, after the cross beam and the side beam are placed in a die groove, the side beam die is pushed to enable the side beam to be sleeved on the cross beam, then welding and subsequent processing procedures are carried out, and after the completion, the auxiliary frame is directly hoisted out through hoisting. Because the inner space of the die groove is compact, the groove wall is tightly attached to the cross beam and the side beams, lateral extrusion force is easy to generate due to shaking and gravity center deviation in the vertical lifting or hoisting process, the abrasion of the inner wall of the die groove can be aggravated, the quick and safe discharging of the auxiliary frame can be influenced, and after the positioning groove is excessively worn, the positioning precision and the positioning stability of subsequent processing are reduced, and meanwhile, the maintenance cost of the tool is increased.
