Abstract
The utility model discloses a combined tool for drilling and milling threads, which comprises a hard alloy drill bit body, wherein one end of the hard alloy drill bit body is a cylindrical drill point, the cylindrical drill point comprises a neck part and a cylindrical blade which are sequentially connected, at least one PCD (polycrystalline Diamond) cutter head with a cutting edge is arranged on the neck part, and the cutting edges on the PCD cutter head are distributed along the axial direction of the neck part. The utility model does not need to change the tool when processing the threaded hole, reduces the number of the multipurpose auxiliary tools during processing, reduces the processing time and greatly improves the processing efficiency.
Description
Technical Field
The utility model belongs to the technical field of machining tools, and particularly relates to a combined tool for drilling and milling threads.
Background
The traditional internal thread processing method comprises the steps of firstly drilling a thread bottom hole by using a proper drill bit, and then manually or mechanically tapping threads by using a single or a group of screw taps, wherein the working procedures are dispersed, a plurality of auxiliary tools are required during processing, the frequency of replacing a cutter is frequent, the processing time is long, and the production efficiency is low; and the tap is easy to break, and if parts are scrapped, a great deal of manpower and cost are wasted because tapping is the last process.
SUMMERY OF THE UTILITY MODEL
In view of the above, the present invention provides a combined cutting tool for drilling and milling threads to solve the deficiencies in the prior art.
In order to achieve the purpose, the utility model is realized by the following technical scheme:
the utility model provides a bore and mill screw thread gang tool, it includes carbide drill cutter body, the one end of carbide drill cutter body is cylindrical drill point, cylindrical drill point is including the neck and the cylinder sword that connect gradually, be equipped with at least one PCD tool bit that has the cutting edge on the neck, the cutting edge on the PCD tool bit along the axial distribution of neck.
According to the drilling and milling thread combined tool, two PCD cutter heads which are symmetrically distributed along the central axis of the neck are arranged on the neck.
The drill and mill thread compound cutter as described, the outer diameter of the neck portion is smaller than the outer diameter of the cylindrical edge.
According to the combined tool for drilling and milling the threads, the number of the cutting edges of the PCD cutter head is controlled to be 5-30 thread pitches, and the diameter of the cutting edge of the PCD cutter head is 3-12 mm.
The technical scheme of the utility model has the beneficial effects that:
the threaded hole is machined without tool changing, the number of multipurpose auxiliary tools during machining is reduced, machining time is shortened, and machining efficiency is greatly improved.
Drawings
To further illustrate the above objects, structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.
FIG. 1 is a schematic view of the structure of the present invention.
Wherein: 1. a cemented carbide drill bit body; 2. a cylindrical drill tip; 3. a neck portion; 4. a cylindrical blade; 5. a PCD bit.
Detailed Description
The utility model is further described with reference to the following drawings and specific examples, which are not intended to be limiting.
Referring to fig. 1, the combined tool for drilling and milling threads comprises a cemented carbide drill bit body 1, wherein one end of the cemented carbide drill bit 1 is a cylindrical drill tip 2, the cylindrical drill tip 2 comprises a neck 3 and a cylindrical blade 4 which are sequentially connected, at least one PCD cutter head 5 with a cutting edge is arranged on the neck 3, and the cutting edges on the PCD cutter head 5 are distributed along the axial direction of the neck 3.
In a preferred embodiment of the present disclosure, two PCD tips 5 are provided on the neck 3, symmetrically distributed along the central axis of the neck 3. The outer diameter of the neck 3 is smaller than that of the cylindrical edge 4, so that part of the structure of the PCD bit 5 can be sunk, and the extra wear condition is reduced. Further preferably, the number of the cutting edges of the PCD tip 5 is determined according to the depth and the pitch of the processed product, and is generally controlled to be 5 to 30 pitches, the diameter of the PCD tip is 3 to 12mm, and the width of the cutting edge is determined according to the requirements of the processed product, so that good cutting capability is realized, and edge breakage is not easy to occur.
The utility model does not need to change the tool when processing the threaded hole, reduces the number of the multipurpose auxiliary tools during processing, reduces the processing time and greatly improves the processing efficiency.
While the utility model has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model.
