An assembly method of an excavator air conditioner indoor unit

Abstract

The invention discloses an assembly method of an air conditioner indoor unit of an excavator, comprising the following steps: installing a speed regulating module (11); installing internal components of the rear casing (2); fastening and installing the front and rear casings; installing an evaporation fan Assembly (3); install heater core assembly (4) and crank; install crank metal connecting rod (5); install mode cam (6); install cam protection cover (7); install damper mode actuator (8 ); install the air inlet shell assembly (9); install electrical components; detect and put into storage. The method for assembling the air-conditioning indoor unit of the excavator does not need to make a special damper installation guide tool when installing the indoor air-conditioning unit of the excavator. Assembly of excavator air conditioner indoor unit.

Description

technical field [0001] The invention relates to an assembly method of an air-conditioning indoor unit of construction machinery, in particular to an assembly method of a plastic shell air-conditioning indoor unit suitable for large and medium-sized excavators, and belongs to the technical field of engineering machinery technical equipment. Background technique [0002] An excavator is an earth-moving machine that uses a bucket to excavate materials such as soil, coal, sediment, or pre-loosened soil and rocks that are higher or lower than the bearing surface, and is loaded into a transport vehicle or unloaded to a stockyard. It has become one of the most important construction machinery in engineering construction. The working environment of the excavator is relatively harsh, which is not conducive to the operator to open the window in the cab. Usually, air conditioners are installed in the cab of the excavator to increase the comfort of the operator. [0003] The air conditi...

Problems solved by technology

[0005] Due to the limited installation space, the indoor units (ie evaporators) of construction machinery air conditioners are usually relatively compact in structure. The installation of components is usually difficult due to the small installation space. Due to the large number of dampers, metal connecting rods, support rods, cams, etc., the installation usually requires multiple assembly operators to cooperate and install, especially for the installation of damper components. One assembly The operator cannot complete the fastening and installation of the front and rear shells independently. Usually, it is necessary to make a special damper installation guide tool, align and guide each damper shaft to the corresponding mounting hole in the front shell, and remove it before the fastening of the front and rear shells. Only tooling can be fastened, which not only results in low installation efficiency, but also complicated installation operations
