Abstract

The utility model aims at providing a drilling and milling screwer, which can effectively improve the working efficiency of internal thread processing, guarantee the quality of products and can also reduce the production cost. The drilling and milling screwer comprises a handle part and an edge part, wherein the edge part is arranged at the end part of the handle part. The drilling and milling screwer has the key points that the edge part is formed by an end edge at the end part and a side edge which is close to the handle part and is provided with threads. When the internal threads are processed, firstly the end edge is contacted with a workpiece so as to drill holes in the workpiece, then the side edge with the threads at the rear end is contacted with the workpiece, thread milling can be carried out on the drilled holes, and tool change is not needed in the whole working process, so that the coaxiality in the hole-drilling process and the thread-milling process is ensured, and further the processing efficiency and the processing quality are improved. The drilling and milling screwer provided by the utility model has the advantages that the structure design is ingenious, and a drilling bit and a milling cutter are combined together, so that the working efficiency of internal thread processing can be effectively improved, the quality of products can be ensured, and meanwhile, the production cost can also be reduced.

Description

A kind of brill thread milling cutter
Technical field
The utility model belongs to cutter manufacturing technology field, specially refers to a kind of brill thread milling cutter.
Background technology
The processing method of tradition internal thread is to process thread Pilot hole with suitable drill bit earlier, and the aperture also needs chamfering, goes thread milling with milling cutter more at last; Its shortcoming is: operation is disperseed, and required lathe and operation are more, and more the number of times of bit change and milling cutter is frequent; Not only productivity ratio is low; And the axiality of drill bit and milling cutter is difficult to guarantee after the tool changing, influence product quality, in production, causes inconvenience.
The utility model content
The purpose of the utility model is to propose a kind of brill thread milling cutter, can effectively improve the operating efficiency of machining internal thread, when guaranteeing product quality, can also reduce production costs.
The brill thread milling cutter of the utility model comprises shank and is installed in the blade of shank end, and key is that said blade constitutes by the end sword of its end with near the side edge with screw thread of shank.
When machining internal thread; At first be that the end sword contacts with workpiece, workpiece holed that the side edge with screw thread of rear end contacts with workpiece then; Can carry out thread milling to the hole of boring; In entire work process, need not to carry out tool changing, guaranteed the axiality of boring procedure and thread milling process, thereby improved working (machining) efficiency and crudy.
Further, said side edge is provided with chamfering, can after thread milling, carry out chamfer machining like this, has further improved working (machining) efficiency and crudy.
The brill thread milling knife structure design of the utility model is ingenious, through drill bit and milling cutter are combined, can effectively improve the operating efficiency of machining internal thread, when guaranteeing product quality, can also reduce production costs.
Description of drawings
Fig. 1 is the structural representation of the brill thread milling cutter of the utility model.
The specific embodiment
Contrast accompanying drawing below; Through description, the effect of the mutual alignment between the shape of the specific embodiment of the utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are done further to specify to embodiment.
Embodiment 1:
As shown in Figure 1, the brill thread milling cutter of present embodiment comprises shank 1 and the blade 2 that is installed in shank 1 end, and blade 2 constitutes by the end sword 3 of its end with near the side edge with screw thread 4 of shank.
When machining internal thread; At first be that end sword 3 contacts with workpiece, workpiece holed that the side edge with screw thread 4 of rear end contacts with workpiece then; Can carry out thread milling to the hole of boring; In entire work process, need not to carry out tool changing, guaranteed the axiality of boring procedure and thread milling process, thereby improved working (machining) efficiency and crudy.
The middle part of side edge 4 is provided with chamfering 5, can after thread milling, carry out chamfer machining like this, has further improved working (machining) efficiency and crudy.

Claims (2)

1. one kind is bored the thread milling cutter, comprises shank and the blade that is installed in the shank end, it is characterized in that said blade constitutes by the end sword of its end with near the side edge with screw thread of shank.
