Abstract
The utility model relates to a machining tool, an efficiency of work is improved specific drill bit of removable cutter. In machine tool machining, in order to increase work efficiency, improve convenience, convenience and the economic nature used. Characterized by: the removable tool bit of drill bit, cutter can be fine monitoring cost to various tool bits, cutter can be cooperated, the demand of different processing work pieces is satisfied.
Description
Technical field
The utility model relates to a kind of rough machinedly repaiies hole instrument, specifically a kind of target drill of removable cutting tool of increasing work efficiency.
Background technology
Drill bit goes out through hole or blind hole in order to drilling on solid material, and can to the cutter of existing hole reaming.And in machine tooling, in order to increase operating efficiency, improve the convenience used, convenience and economy, the drill bit of this interchangeable bit, cutter just arises, and can well control cost, and various cutter head, cutter can be coordinated, meet the demand of different processing work.
Utility model content
The purpose of this utility model is a kind of target drill of removable cutting tool of increasing work efficiency.
A kind of target drill of removable cutting tool of increasing work efficiency, main body is staight shank drill body and cutting blade, its innovative point is: described staight shank drill body is cylinder, described staight shank drill body has chip area, described cutting blade has two, form chip area between cutting edge portion rotational trajectory, described cutting blade has the hole that two can be changed cutter.
Further, the length of described staight shank drill body is 25 ~ 35cm.
Further, described cutting blade is parallel with horizontal line.
Further, described cutting blade has the hole that two can be changed cutter.
Further, described drill body is cylinder, and its length is 10 ~ 15cm.
Further, described drill body becomes stepped, and front end is thick, and rear end is thin.
The beneficial effects of the utility model are:
1, straight shank drill described in the utility model is one-body molded, through quenching technical process, sturdy and durable, has certain toughness, not fragile.
2, the utility model drill bit is provided with two blades, and the design of the angle that blade is carried out and structure, parallel with horizontal line, be convenient to the installation of cutter head, cutter.
3, be provided with in blade described in the utility model two can mounting cutter, cutter head hole, different cutters can be changed at any time, meet the requirement of different processing work.
4, drill body described in the utility model adopts described drill body to become stepped, and front end is thick, and rear end is thin, can meet the use of the drilling attachment of all size.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
Fig. 1 is structural scheme of mechanism of the present utility model.
Fig. 2 is the cutting end view of the utility model drill bit.
Detailed description of the invention
Straight shank drill as shown in Figure 1, by drill body 1, drill body 2, chip area 3, cutting blade 4, the hole 5 of removable cutting tool is formed.
The structure of straight shank drill is as shown in Figure 1: drill body 1 is cylinder, the total length of drill body is 15 ~ 20cm, handling and the use of straight shank drill are mainly considered in the design of this structure, too shortly not easily to install, oversize poor stability, and adopt described drill body to become stepped, front end is thick, rear end is thin, can meet the use of the drilling attachment of all size.
One end of straight shank drill is drill body 2 as shown in Figure 1, and the upper and lower side of drill body 2 is provided with cutting blade 4, and described cutting blade 4 has two, is in a center of symmetry about the rotary middle spindle of drill body.
Described drill body 2 has chip area 3, during processing work, cuts the bits material produced and automatically discharge from chip area 3.
Described drill body 1 adopts described drill body to become stepped, and front end is thick, and rear end is thin, can meet the use of the drilling attachment of all size.
During processing work, the drill jig of electric drill firmly clamps drill body 1, and assembling is applicable to the cutter of workpiece to be processed on installing hole 5, and first institute's dress cutter contacts processing work surface, and carry out preparatory processing, then cutting blade 4 starts to contact processing work, and produces a large amount of material bits, and material bits are automatically discharged from chip area 3, and the cutting blade 4 of level can be good at controlling cutting direction, be unlikely to damage processing work, the accumulation of expecting bits will be noted especially, prevent from damaging cutter.
The above is preferred embodiment of the present utility model, can not limit the interest field of the utility model with this.It should be pointed out that for those skilled in the art, the technical solution of the utility model is modified or equivalent replacement, do not depart from protection domain of the present utility model.
