Abstract
The utility model discloses a reamer holder which comprises a reamer head and a reamer handle. The reamer head is composed of spiral reamer teeth and tooth grooves, thread holes which are used for mounting and fixing blades are arranged at the ends of the reamer teeth. According to the reamer holder, the blades can be dismounted, replaced and used at any time, the times of recycling of the reamer holder are improved, and processing cost is lowered. A chip groove discharges chips in a spiral mode so that smoothness is achieved, a water outlet is arranged inside each tooth groove so that cooling effect is good, and a cutting effect is improved obviously.
Description
Technical field
The utility model relates to a kind of reamer holder.
Background technology
Ream is processing method the most frequently used in the machining, and blade and the knife bar of cutter are whole welding types usually.Blade often damages easily, in case breaks down, whole cutter has just been scrapped, and the production and processing cost is high.
The utility model content
The purpose of this utility model provides the reamer holder that a kind of blade separates with knife bar, cuts down finished cost.
For achieving the above object, the technical solution adopted in the utility model is:
Reamer holder comprises cutter head and handle of a knife, and described cutter head is comprised of spirality cutter tooth and teeth groove, and the cutter tooth end is provided be used to the screwed hole that installs and fixes blade.
Described cutter tooth has four, and helical angle is 25 °～30 °.
Described knife bar center is provided with the water hole; Be equipped with the delivery port that is communicated with the water hole in the described teeth groove.
In the utility model, blade at any time dismounting and change uses, and has improved the recycling number of times of knife bar, has reduced processing cost; Chip area is that spiral chip removal is more smooth and easy, sets out the mouth of a river in each teeth groove, and good cooling results significantly improves cutting effect.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model cutter head end construction schematic diagram.
The specific embodiment
As shown in Figure 1 and Figure 2, reamer holder comprises cutter head and handle of a knife 1, and described cutter head is comprised of spirality cutter tooth 3 and teeth groove 2, and cutter tooth 3 ends are provided be used to the screwed hole 5 that installs and fixes blade 4.Cutter tooth 3 has four, and helical angle is 25 °～30 °.The knife bar center is provided with water hole 6; It is obstructed at the cutter head end to be equipped with the delivery port 61(water hole 6 that is communicated with water hole 6 in the teeth groove 2, is communicated with delivery port 61 from handle of a knife 1 end).
In the utility model, handle of a knife 1 adopts the staight shank installation way, but universal standard chuck, clamping is stable, and the scope of application is wide; Blade 4 adopts PCD or CBN, and high-speed cutting improves working (machining) efficiency, cuts down finished cost, and improves the stability of product; Blade 4 centers with holes directly by screw in compression on cutter tooth 3, and blade 4 adopts standard insert, guaranteed the fastness of blade and the commutativity of blade.
