Abstract
The invention aims to provide a drilling and milling screwer, which can effectively increase the working efficiency of the internal thread processing and reduce the manufacturing cost while ensuring the product quality. The drilling and milling screwer comprises a handle part and a blade part which is installed on an end part of the handle part. The key is that the blade part consists of an end blade on the end part and a side blade with a thread and near the handle part. When the internal thread is processed, firstly, the end blade and a workpiece are made in contact with each other to drill the workpiece, and then, the side blade having the thread at the rear end and the workpiece are made in contact with each other for thread milling of the drilled hole, the tool replacement is not needed in the entire working process, the coaxiality of the drilling process and the milling process can be ensured, thereby increasing the working efficiency and the processing quality. The drilling and milling screwer is ingenious in structural design, can effectively increase the working efficiency of the internal thread processing and reduce the manufacturing cost while ensuring the product quality by combining a drilling head with a milling cutter.
Description
Technical field
The invention belongs to cutter manufacturing technology field, specially refer 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.
Summary of the invention
The objective of the invention 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.
Brill thread milling cutter of the present invention 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.
Brill thread milling knife structure design of the present invention 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 brill thread milling cutter of the present invention.
The specific embodiment
Contrast accompanying drawing below; Through the description to embodiment, the effect of mutual alignment between the shape of specific embodiments of the invention such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are done further to specify.
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.
2. brill thread milling cutter according to claim 1 is characterized in that said side edge is provided with chamfering.
