Rotating disc type multiple station drilling machine for processing crankshafts and processing method thereof

Abstract

The invention relates to the technical field of drilling, in particular to a rotating disc type multiple station drilling machine for processing crankshafts. The rotating disc type multiple station drilling machine for processing the crankshafts comprises a rotating disc and a rotating disc power device used to drive the rotating disc to rotate, wherein multiple work stations which can fix work pieces are arranged on the rotating disc, a first drilling device used to form axial holes in the work pieces, a milling device used to mill the total length of the work pieces, a third drilling device used to process oblique oil holes in the work pieces and a forth drilling device used to process axial oil holes in the work pieces are sequentially arranged around the rotating disc and along the rotation direction of the rotating disc, and the first drilling device, the milling device, the third drilling device and the forth drilling device can perform corresponding, multilevel and progressive circulating processing on each work piece on each work station during the rotation process of a rotating platform. The rotating disc type multiple station drilling machine for processing the crankshafts is simple in structure and strong in practicality.

Description

technical field [0001] The invention relates to the technical field of crankshaft drilling, in particular to a rotary multi-station drilling machine for machining crankshafts and a machining method thereof. Background technique [0002] The crankshaft is the power transmission component of the piston compressor. External power such as a motor transmits power to the compressor through the crankshaft, and the crankshaft drives another compressor component installed on it—the connecting rod, which converts rotary motion into reciprocating motion, thereby realizing the work of the piston compressor. [0003] The crankshaft includes a long shaft and a centrifugal part. In the production process, a qualified crankshaft often needs to open an axial hole on the crank, an oil hole passing through the centrifugal part and the long shaft, and control the length of the crankshaft. The oil hole includes axial oil. At the same time, in order to produce crankshafts with higher quality and...

AI Technical Summary

Problems solved by technology

[0004] The traditional crankshaft processing method is often an assembly line. Each station needs to be equipped with an operator, so that the cost continues to rise. In the assembly line processing method, after completing a process, the workpiece needs to be taken out and fixed in the fixture of the next process. In the next process, the workpiece needs to be positioned frequently, and there will be deviations or errors in each positioning, which reduces the accuracy and production efficiency

At the same time, the scope of the operation site is large and the requirements are high, which is not suitable for the production of small processing enterprises. Finally, in the process from one process to the next process, the workpiece has a large fluidity, which makes the workpiece easy to be damaged or lost in the process of transportation.
