Gate-type overturning mechanism for refrigerator car skin

Abstract

The invention discloses a gate-type overturning mechanism for refrigerator car skin. The gate-type overturning mechanism comprises a first conveying belt, a second conveying belt, a power roller path, an overturning mechanism body, a lifting mechanism and a power roller path lifting mechanism. The overturning mechanism body comprises an overturning rack and a rotating shaft. The overturning rack is connected with crash pads through the rotating shaft. The lifting mechanism is arranged below the overturning rack and comprises a fourth machine frame, a first air cylinder, a first piston rod, a first connecting rod and a second connecting rod. The power roller path lifting mechanism is fixedly connected with the power roller path. The power roller path is arranged below the crash pads. The power roller path lifting mechanism comprises a fifth machine frame, a second air cylinder, a second piston rod and a sixth machine frame. According to the gate-type overturning mechanism disclosed by the invention, no clamping mechanism is required, and accordingly the problems that overturning is inconvenient and the polishing stroke is insufficient in the polishing process of the refrigerator car skin can be solved. By the adoption of the gate-type overturning mechanism, time consumed from the welding process to the polishing process of the skin is effectively shortened.

Description

technical field [0001] The invention relates to an overturning mechanism, in particular to an overturning mechanism for a skin of a refrigerated vehicle. Background technique [0002] The body panels of refrigerated and insulated vehicles generally adopt a "sandwich" panel structure, with inner and outer skins and insulation layers. Generally, the outer skin is aluminum, the inner skin is aluminum or stainless steel, and the insulation layer is filled with polyurethane foam. The inner and outer skins are welded by an automatic welding machine. In order to improve the bonding strength, the bonding surface of the welded skin is polished and cleaned and sprayed. Ultra-wide (more than 6 meters) skin, welded on the front, and polished on the reverse side of the skin. [0003] In the traditional operation process from welding to grinding, workers use adhesive tape to bond the welded part of the skin to avoid disconnection of the welded part due to the gravity of the skin. The sk...

Problems solved by technology

The disadvantages of this method are: (1) When the workers are turning over the skin or the truss is transporting the skin, due to factors such as the weight of the skin or the welding is not firm, it is easy to cause the skin to fall off and cause injury to the worker; (2) Due to the large length of the skin, there are strict requirements on the height of the factory building. If the height of the truss is not enough, it is easy to cause the skin to bend when the skin is turned over, forming turning creases, which affects the appearance; (3) because the skin is too long, the grinding The stroke is not enough, which reduces the grinding efficiency
