Abstract

The utility model relates to a machine tool cutter used on a numerical control machine tool, in particular to a combined cutter for processing a gear box shell, which comprises a cutter bar and a cutter head connected to one end of the cutter bar, and is characterized in that one end of the cutter head is provided with a plurality of annular steps which constitute a stepped inner round table and a stepped outer annular table at the end part of the cutter head, the steps are provided with grooves from installing cutting tools, combined cutting tools are arranged in the grooves, the cutting edges of the cutting tools are fixed on cutting tool bodies through bolts at the centers, and the cutting edges are formed into cutting edges on the surface of the round table. In the combined cutter, a plurality of cutting tools are arranged in the same cutter, so a plurality of positions are processed once, and the cost of the cutter and the processing time of products are reduced. The combined cutter can be used on various machine tools, solves the problem that the secondary positioning precision of a machine tool with an unchangeable cutter is difficult to control, and improves the cutting precision.

Description

A kind of gang tool of processing gear box casing
Technical field
The utility model relates to the machine tool that uses on a kind of Digit Control Machine Tool, specifically is a kind of gang tool of processing gear box casing.
Background technology
At present, along with people are more and more higher to the performance requirement of automobile, also more and more higher to the requirement on machining accuracy of auto-parts.In the processing of gear box casing, because to be processed on the gear box casing is more, the tolerance fit between each machined surface is strict, so need higher processing precision.And in process, the general hilted broadsword head that adopts is processed during owing to processing work, can not once finish all to be processed, requires processing step by step, and lathe then needs to change back and forth cutter, so the product that processes is easy to generate deviation, influences crudy.And in lathe, need to be equipped with a plurality of cutters, increased the purchase cost of cutter.
Summary of the invention
The utility model provides a kind of gang tool of processing gear box casing in order to overcome the defective that above-mentioned prior art exists, and can reduce number of changing knife, improves the precision of processing.
The utility model is achieved through the following technical solutions: a kind of gang tool of processing gear box casing, this cutter comprises knife bar and is connected the cutter head of knife bar one end, one end of described cutter head is provided with some annular steps, described step the end of cutter head form stepped in round platform and stair-stepping outer shroud platform, described step is provided with the groove that bite is installed, be provided with the combined type bite in the described groove, by being bolted on the cutting cutter hub, blade forms cutting edge to the blade of bite on round table surface in the center.
The utility model also has following characteristics: in order to process positions different on the gear box casing simultaneously, first bite and the tenth bite are installed on the excircle of described cutter head, and first bite and the tenth bite are respectively on two different circumference; The outer shroud platform step adjacent with the tenth bite is provided with the 9th bite; On the adjacent outer shroud platform step of described first bite, be provided with the 3rd bite and second bite; Be respectively equipped with the 4th bite, the 5th bite, the 6th bite, the 7th bite and the 8th bite on the different steps of round platform in described.
In order to improve cutting effect, the cutting edge of described bite becomes 45 with the periphery of cutter head oThe angle.
The beneficial effect of this programme can be learnt according to above-mentioned, because an end of described cutter head is provided with some annular steps, described step the end of cutter head form stepped in round platform and stair-stepping outer shroud platform, described step is provided with the groove that bite is installed, be provided with the combined type bite in the described groove, by being bolted on the cutting cutter hub, blade forms cutting edge to the blade of bite on round table surface in the center.This cutter is installed in a plurality of bite settings same as in the cutter, makes a plurality of positions of time processing, has reduced the cost of charp tool and product process time.The utility model can use multiple different lathe, has solved the problem that some can not tool changing lathe secondary location difficulty, has improved cutting accuracy, has shortened technological process, has improved production efficiency.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
