Embodiment Construction
[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:
[0034] In order to realize the milling of two lugs at one time and ensure the machining accuracy, one of the keys of the present invention is to realize that the third disc milling cutter and the third disc milling cutter and the second disc milling cutter can mill a certain cutting edge after the first disc milling cutter and the second disc milling cutter are milled out. A certain chip edge of the four-disk milling cutter is milled in, and after the chip edge of the third-disk milling cutter and the fourth-disk milling cutter is milled out, the next cutting edge of the first-disk milling cutter and the second-disk milling cutter is milled in, that is, any one Only one of the lugs is processed at a time, which can prevent the machine tool from vibrating due to excessive cutting force when processing two lugs at the same time, thereby improving ...

The invention discloses a double lug processing method and device, using the same first disk milling cutter, second disk milling cutter, third disk milling cutter and fourth disk milling cutter which are completely identical and sequentially assembled on the same spindle Milling the inner and outer end faces of the two lugs, in which two Lug Thickness L 1 , by controlling the distance between the second disc milling cutter and the third disc milling cutter to process the distance L between the inner end faces of the two lugs 2 ; The first disk milling cutter and the second disk milling cutter are assembled mirror-symmetrically, the third disk milling cutter and the fourth disk milling cutter are mirror-symmetrically assembled, and the cutting edges on the first disk milling cutter and the second disk milling cutter are the same as the third disk milling cutter The cutting edges on the disc milling cutter and the fourth disc milling cutter are staggered by an included angle θ. The invention can improve the feature processing efficiency and pass rate of the double lug.
Description
technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a processing method of a part with lugs, in particular to a method and a device for machining two lug features with a single feed of a disc milling cutter on a horizontal milling machine. Background technique [0002] like Figure 1 to Figure 4 Shown is a schematic of the part for the two tab features. The lugs are mainly used for connection with other parts, and need to be processed to ensure the thickness L of the lugs 1 , the distance L between the two ear pieces 2 and the distance L from the center of the hole to the step 3 . [0003] At present, the processing method of this type of lug feature is to ensure part of the size by one feed, and then divide the feed in multiple times to ensure the whole size. This kind of method has the following disadvantages: low processing efficiency; when feeding in multiple times, the subsequent feeding will affect the size f...
