Description

Technical Field

[0001] The utility model relates to the field of automobile air-conditioning compressor processing tooling, in particular to a universal tooling for deburring the cross hole of a main shaft of an automobile air-conditioning compressor. Background Art

[0002] The main shaft of the automobile air-conditioning compressor is the power transmission component of the automobile air-conditioning compressor. It is driven by the power of the automobile engine to drive the swash plate of the automobile air-conditioning compressor to rotate. Figure 1 As shown, it is a shaft-like structure with multi-stage diameter reduction, with two transverse holes 14 perpendicular to the central axis on the circumferential surface, and cross holes 11 connected to the two transverse holes 14 along the axis, connecting the inner cavity of the rear cover of the automobile air-conditioning compressor and the inner cavity of the cylinder body, and spraying the lubricating oil from the inner cavity of the rear cover through the cross hole 11 from the two transverse holes 14 to lubricate the sliding plate arranged in the inner cavity of the cylinder body. In the prior art, the transverse hole 14 and the cross hole 11 are both drilled by a drilling machine, and after processing, there are usually many burrs attached and gathered in the air. The existence of these burrs is very likely to block or hinder the conduction flux of the transverse hole 14 or the cross hole 11, affecting the circulation of the lubricating oil, so it is necessary to deburr them after processing. Since the depth of the cross hole 11 is relatively large, the difficulty of removing the burrs is relatively large. The traditional processing method is for workers to manually handle the burrs one by one by holding multiple pieces of automobile air-conditioning compressor main shafts and a handheld electric drill with a brush in both hands. Not only is the labor intensity high, but the operation efficiency is low, and it is also easy to lose the order and miss individual workpieces, affecting the quality of the automobile air-conditioning compressor. Therefore, it is necessary to improve the processing method of deburring the cross hole of the automobile air-conditioning compressor main shaft, research and develop matching tooling fixtures, reduce the labor intensity of workers, improve the operation efficiency, improve the removal effect, and ensure the product production quality of the automobile air-conditioning compressor.
