Description

Technical Field

[0001] The utility model relates to the field of welding processing, in particular to a riveting welding tool for a chassis of a sanitation vehicle. Background Art

[0002] As the instruction manual Figure 1 and attached Figure 2 As shown, an existing sanitation vehicle box bottom plate assembly includes a bottom plate and a chassis welded to the bottom surface of the bottom plate, the chassis includes two parallel longitudinal beams A located in the middle of the bottom plate, a plurality of cross beams (including a front cross beam B, a rear cross beam C and a middle cross beam) located between the two longitudinal beams and on both sides thereof, a lifting cylinder seat D located between the two longitudinal beams and a latch plate assembly E located at one end of the chassis, wherein the lifting cylinder seat is welded by a cylinder seat cross beam D-1, a rib plate and an articulated seat D-2, the two ends of the cylinder seat cross beam are welded between the two longitudinal beams through the rib plate, and the two articulated seats are welded to the side of the cylinder seat cross beam.

[0003] The welding process of the above-mentioned base plate assembly is as follows: first weld the base frame, then weld the base plate to the base frame. When welding the base frame, the position accuracy of the lifting cylinder seat needs to be guaranteed, and the two hinged seats of the lifting cylinder seat need to be coaxial. The latch plate assembly E includes two vertical plates E-1 and an inclined base plate E-2. One end of the two vertical plates is welded to the rear crossbeam C of the base frame, and the base plate is welded at an angle to the bottom of the other end of the two vertical plates. The position accuracy of the latch plate assembly needs to be guaranteed during welding. The existing welding method can be referred to the attached manual. Figure 3 , a positioning template and a clamping handle are set at the designed position on the welding platform, and the longitudinal beam, cross beam and cylinder seat cross beam of the lifting cylinder seat are positioned with the positioning template and then spot welded, and the two articulated seats are welded by manual measurement and marking. This welding method is difficult to ensure the position accuracy and coaxiality of the two articulated seats; in addition, the welding of the latch plate assembly is also manually welded through marking measurement. During the specific welding, the vertical plates on both sides are welded first, and then the bottom plate at the other end of the vertical plate is welded. Due to the lack of a positioning device, it is difficult to ensure the inclination and position of the bottom plate, so that the welding accuracy of the latch plate assembly cannot be guaranteed.

[0004] Based on this, the present application provides a riveting and welding tool for the chassis of a sanitation vehicle to solve the above problems. Utility Model Content
