Description
Technical Field
The utility model belongs to the technical field of the worm processing, concretely relates to flat square plate of worm mills location frock.
Background
In the prior art, a worm milling flat square is formed by indexing by using an indexing head on a milling machine, and machining by using a rod milling cutter in a mode of clamping and jacking. Because the flat square outer circle of the worm has different sizes, the worm is formed by one-step processing by adopting a rod milling cutter. When the rod milling cutter mills from the outer circle of the worm to the middle part of the worm gradually, the milling allowance of the middle part of the flat square of the worm is larger, and the flat square always presents a concave phenomenon. On one hand, the larger the outer circle of the worm is, the more serious the flat square concave phenomenon is when the rod milling cutter is used for processing. The parallelism of the flat squares cannot meet the requirements of users. The worm adopts a processing mode of clamping one top, and the tightness of the top can also influence the concave amount of the flat square of the milling and clamping tool. And after one surface of the flat square is milled, manually rotating the dividing head by 180 degrees to process the other surface of the flat square. Hand dividing head divides, and the location of dividing head also can have certain angle error, also can influence the flat square symmetry of worm like this. That is, the prior art adopts one to press from both sides one, and such processing mode of hand dividing head graduation all has following drawback: 1. the flat square of the worm is milled by adopting a mode that the dividing heads clamp one top, so that the operation is slow, and the division has errors. Therefore, the production efficiency is reduced for the processing of batch products, and the processing quality of batch flat worms cannot be ensured. 2. And (5) carrying out one-time processing by adopting a rod milling cutter. Because the grinding degree of the rod milling cutter is inconsistent, the length of the cutter bar is different to a certain extent. The cutter bar is too long, so that the phenomenon of bullet shooting can occur during milling, and the symmetry of the processed product cannot be guaranteed. This also does not fully guarantee the quality of mass production.
