Description

Technical Field

[0001] The invention belongs to the technical field of crankshaft processing equipment, and in particular relates to a compressor crankshaft inclined hole processing equipment. Background Art

[0002] The crankshaft is the most important component in the compressor. It is subjected to the combined effects of the centrifugal force of the rotating mass, the periodically changing gas inertia force and the reciprocating inertia force, which causes the crankshaft to be subjected to bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface must be wear-resistant, work evenly and have good balance.

[0003] During the machining process of a crankshaft, it is often necessary to open an inclined hole on the crankshaft. When machining the inclined hole with traditional drilling equipment, the crankshaft is generally tilted and fixed on the machining platform of the drilling equipment, and the inclined hole of the crankshaft is machined by manually operating the drilling equipment. When machining the crankshaft with the above method, there are large differences between individuals, resulting in large errors in the inclination angle of the crankshaft, and only one crankshaft can be machined at a time, resulting in low machining efficiency of the crankshaft inclined hole and high labor intensity for workers.
