Pin press-fitting machine for assembling automobile air conditioner compressor base and application method of pin press-fitting machine

Abstract

The invention discloses a pin press-fitting machine for assembling an automobile air conditioner compressor base and an application method of the pin press-fitting machine. The lifting of a horizontalpushing mechanism, a pre-pressing pin combination plate and a hanging bracket assembly part is achieved through a vertical lifting mechanism. The pre-pressing pin combination plate is in contact witha flange surface at an upper end of the base, pin holes in the pre-pressing pin combination plate are aligned with pin hole positions in an upper surface of the base, the initial state of a push plate is that pin holes in the push plate are aligned with the pin holes in a pin guide-in plate, and after cylindrical pins are distributed in the pin holes of a pin distribution disc through a vibrationdistribution machine, lower ends of the cylindrical pins are inserted into the pin holes in the push plate. And a pushing air cylinder works, and the push plate pushes the cylindrical pins forwards along grooves in the pin guide-in plate until lower parts of the cylindrical pins are inserted into the pin holes in the pre-pressing pin combination plate. The accurate alignment of pin holes in the pre-pressing pin combination plate and pin hole positions in the base can be ensured, the pre-pressing depth of the cylindrical pins, the perpendicularity after pre-pressing and the uniform distribution of the cylindrical pins on a flange face of the base can be guaranteed.

Description

technical field [0001] The invention relates to a base assembly device for an automobile air-conditioning compressor, in particular to a pin press-fitting machine for base assembly of an automobile air-conditioning compressor and an application method thereof. Background technique [0002] The automotive air-conditioning compressor is an electric scroll compressor. The electric scroll compressor is a volumetric compression compressor. There are many structural features in the way the road flows to reduce oil entrainment. [0003] After entering the casing, some of the gas flows upward to reduce the amount of gas flowing downward towards the oil. To achieve this, the motor of the compressor may be surrounded by a sleeve having upper and lower holes for directing air flow to the upper and lower stator end turns of the motor. In some embodiments, it is important to position the suction inlet relative to the two gas passages between the stator and the motor housing. The inlet...

Problems solved by technology

[0012] It can be seen from step (3) that the diameter of the pin hole on the guide plate of the straight pin is slightly larger than the diameter of the straight pin, while the diameter of the pin hole on the upper surface of the base is smaller than or equal to the diameter of the straight pin, so the single straight pin cannot be guaranteed Its verticality, that is, it cannot guarantee that the cylindrical pins and the pin holes on the upper surface of the base are coaxial with the center line, so after pressing the six cylindrical pins at the same time through the press, the uniform distribution of the cylindrical pins cannot be guaranteed, which will affect the The smooth assembly of one process increases the scrap rate

[0013] In addition, for batch processing and assembly, a large number of manual operations are required to be repeated, which is cumbersome, labor-intensive, and production efficiency is low.
