Embodiment 1
[0056] Embodiment 1: process high precision gear (as attached Figure 6 , 7 shown):
[0060] From the above two examples, it can be seen that all the content from quenching and tempering to gear cutting is completed in one clamping (including the handover of C-axis and C2-axis workpieces), such as turning, milling, drilling, reaming, rolling, etc. process. The entire machining process basically avoids the influence of human factors. All the dimensional accuracy and shape and position accuracy of the gear are completely determined by the accuracy of the machine tool and the tool itself. Therefore, product precision is guaranteed while improving production efficiency.
[0061] Since the spindle speed of the turning and milling center is as high as 10,000rpm, it can completely replace grinding in some occasions. Therefore, all the processes of gear datum and tooth shape correction can also be completed in one clamping on the turning-milling machining center, thus ensuring the fina...

Abstract
The invention relates to a method for processing machine elements. The method comprises: processing a workpiece by alternating two clamping components; and keeping the workpiece move along the same straight line during the process of alternating clamping the workpiece by one clamping component into clamping the workpiece by the other clamping component. Fixtures for realizing the method comprise a first chuck and a second chuck, wherein the first chuck rotates along a C shaft, and the second chuck can rotate along a C2 shaft; shaft axis of the C shaft and the C2 shaft are in the same straight line; the C shaft and the C2 shaft rotate at the same speed and along the same direction; and the C2 shaft moves forward and backward along the shaft axes thereof, and a clamping unit is arranged on processing equipment. By utilizing the primary clamping technology, the invention can continuously finish multiple cutting procedures of the machine elements, and all the process segments of element production from a semifinished product to a finished product can be finished by the device provided by the invention, thereby shortening production cycle of products; and simultaneously, primary clamping can also completely avoid the influence of personal factors during the production, and fundamentally overcomes the accumulation of aligning and positioning errors and working procedure errors, thereby remarkably improving the processing accuracy.
Description
technical field [0001] The invention relates to a processing method of mechanical parts, in particular to a processing method of gears, as well as a clamping unit and processing equipment for implementing the processing method. Background technique [0002] In the traditional processing technology, the processing methods of transmission gear mainly include milling, inserting, rolling, grinding and other processes. The cutting process includes the following steps: [0003] Step 1: blank preparation, including blank forging, normalizing, rough turning, quenching and tempering, etc.; [0004] Step 2: Gear blank processing, from rough turning scale to all processes before gear cutting, including rough turning descaling, finishing turning, rough grinding, [0005] Step 3: Gear cutting processing, mainly including tooth surface processing such as milling, hobbing, shaping, and shaving; [0006] Step 4: Auxiliary process, chamfering, rounding, deburring and other auxiliary proces...
