Description

Technical Field

[0001] The utility model relates to a shaft processing device, in particular to a rough and fine double-head shaft tooling. Background Art

[0002] A shaft is a supporting rotating part in mechanical equipment, generally used to transmit motion and power, such as crankshafts and drive shafts. Shafts are divided into cast shafts and forged shafts according to the production method. Cast shafts are generally made by melting the metal, pouring it into a mold, cooling it into shape, and then going through machining steps such as turning, milling, and drilling to obtain the finished product; forged shafts are generally made by hammering a metal block after heating it, and also going through machining steps such as turning, milling, and drilling to obtain the finished product. In the shaft processing process, it is generally divided into two steps. The first step is roughing to remove most of the impurities and excess materials on the surface, and wait until the size is close to the rough blank of the finished product. The second step is to fine-process the surface of the rough blank so that the product size and accuracy meet the design requirements.

[0003] Two-step processing can improve processing accuracy, reduce scrap rate, and reduce production costs. However, the two-step processing method will increase production time, and the coaxiality needs to be adjusted during processing, which increases processing errors. In addition, the existing double-head processing equipment can process the workpiece from the connecting edge at the same time, but it is generally fixed in the middle and feeds from both ends. The equipment that feeds from both ends is only suitable for longer workpieces. Utility Model Content
