Automatic pressing assembling device for middle bearings and anti-rotation pins in automobile air conditioner compressor

Abstract

The invention discloses an automatic pressing assembling device for middle bearings and anti-rotation pins in an automobile air conditioner compressor and belongs to the technical field of automobileair conditioner compressor assembling, and a wire body mechanism is located on the adjacent side of a rack mechanism. A middle bearing seat moving mechanism is arranged over a wire body tool plate andconnected with the rack mechanism. A main tool moving mechanism is arranged above the rack mechanism. A bearing distribution mechanism and a bearing moving mechanism are arranged above the rack mechanism. Bearings are automatically fed into a main tool mechanism. An anti-rotation pin automatic feeding mechanism is located on the side of the rack mechanism. An anti-rotation pin indexing mechanismis fixed to the rack mechanism. An anti-rotation pin taking mechanism is located above the anti-rotation pin indexing mechanism and is fixed behind a pressing assembling mechanism. The pressing assembling mechanism is fixed to the center of the rack mechanism, and a middle bearing pressing assembling mechanism and an anti-rotation pin pressing assembling mechanism are installed at the front portion and the rear portion of the rack mechanism. By means of the automatic pressing assembling device, pressing assembling of middle bearings and multiple anti-rotation pins can be conducted at the sametime, the integration degree is high, meanwhile, the pressing assembling quality can be judged according to the pressing assembling force, the pressing assembling precision is ensured, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of assembly of automobile air-conditioning compressors, and in particular relates to automatic press-fitting equipment for bearings and anti-rotation pins in automobile air-conditioning compressors. Background technique [0002] With the substantial increase in the utilization rate of automobiles in my country, the demand for automobile air-conditioning compressors as the main parts of automobiles has also increased significantly. The assembly process of medium bearings and anti-rotation pins is the core part of the process, and the assembly of existing equipment for medium bearings It is still manual pressing or semi-automatic assembly, which is difficult to meet the normal production efficiency and precision requirements. [0003] During the anti-rotation pin assembly process, it is impossible to complete a large number of press-fits at the same time, and the depth of the press-fit cannot be guaranteed, whi...

[0002] With the substantial increase in the utilization rate of automobiles in my country, the demand for automobile air-conditioning compressors as the main parts of automobiles has also increased significantly. The assembly process of medium bearings and anti-rotation pins is the core part of the process, and the assembly of existing equipment for medium bearings It is still manual pressing or semi-automatic assembly, which is difficult to meet the normal production efficiency and precision requirements

[0003] During the anti-rotation pin assembly process, it is impossible to complete a large number of press-fits at the same time, and the depth of the press-fit cannot be guaranteed, which cannot meet the existing 5±0.2mm accuracy requirements, and the press-fit force of each anti-rotation pin cannot be fed back simultaneously, so as to detect no assembly quality
