Description

technical field [0001] The invention relates to a crankshaft processing mechanical device, in particular to a crankshaft flange plate stable nail hole processing machine tool. Background technique [0002] The crankshaft is the heart of the engine, and the bolt hole on the flange is the reference point for machining the crankshaft, which requires very high precision. The process of processed products requires testing the diameter, depth, position, wall thickness, and angle and other parameters. [0003] Machining the stable nail hole is an essential and important process in the production process of the crankshaft. In the past, it mainly relied on the Z3040 radial drilling machine to process it manually. The labor intensity of the operator was high, the processing efficiency was low, and the workpiece accuracy was poor. , For example, Z3050 radial drill operators consume a lot of manual operation, are prone to occupational diseases such as frozen shoulder, low processing ef...

[0003] Machining the stable nail hole is an essential and important process in the production process of the crankshaft. In the past, it mainly relied on the Z3040 radial drilling machine to process it manually. The labor intensity of the operator was high, the processing efficiency was low, and the accuracy of the workpiece was poor.

, such as Z3050 radial arm drill operator manual operation consumes a lot of physical strength, is prone to occupational diseases such as frozen shoulder, low processing efficiency, and large fluctuations in product quality.
