Abstract
The utility model discloses a spindle reduction sleeve of a boring and milling machine. The spindle reduction sleeve comprises a main body, a pulling claw and a pulling rivet, wherein the main body is divided into an upper half part and a lower half part; a conical inner hole is formed in the upper half part; the lower half part with a conical outer surface is welded at the eyelet end of the conical inner hole; an inner hole is formed in the lower half part; the pulling claw is arranged in the inner hole of the lower half part of the main body; one end of the pulling claw is used for fixing a cutter, and the other end of the pulling claw is arranged at the top end of the pulling rivet; a reset spring is arranged on a shaft of the pulling rivet. The spindle reduction sleeve of the boring and milling machine serves as a conversion joint with a spindle specification, an original cutter system can also be directly used, a large cutter does not need to be specially customized, and a cutter on a small machine tool can also be used, so that the using cost is greatly reduced.
Description
Technical field
The utility model relates to heavy boring and milling machine main shaft translation interface, relates in particular to a kind of boring and milling machine main shaft drill holder.
Background technology
Because large-scale boring and milling machine main shaft specification is larger, the cutter using and handle of a knife are not only expensive but also weight is very large, tens kilograms at least of single-piece tool weight, heavy reach dozens or even hundreds of kilogram, present heavy manufacturing procedure is all more concentrated, a lot of operations is all to complete above concentrating on a number of units controlled machine, and this just need to will change a considerable amount of cutters to meet processing request in the process of work.If all just need considerable heavy knife bar according to the supporting cutter of main shaft specification of heavy machine tool, weight is very large, price is high, workman's tool changing labour intensity is very large, increase spacer shell in the middle of also wanting with small-sized cutter in time, affects rigidity and required precision, and every cutter all will be joined to a spacer shell, good multicutter is also wanted specialized designs, on market, can't buy.User purchases supporting very inconvenient.
Utility model content
The utility model, for the defect of prior art, has proposed a kind of boring and milling machine main shaft drill holder, is the equal of the translation interface of main shaft specification, can directly use the cutter on middle-size and small-size lathe, and not needing often all will increase cutter spacer shell and affect precision.
A boring and milling machine main shaft drill holder, comprises
Main body, described main body is divided into the first half and Lower Half, and the first half has a tapered bore, and tapered bore aperture one end is welded with the Lower Half of conical external surface; Described Lower Half has an endoporus;
Pulling claw, is installed in main body Lower Half endoporus, and pulling claw one end is for fixed cutting tool, and the other end is arranged on the top of blind rivet;
Blind rivet, is provided with back-moving spring on the axle of described blind rivet.
In preferred described main body, have the installing hole for being connected with boring and milling machine main shaft.
In preferred described main body, be provided with for limiting the locating piece of tool position.
In preferred described main body, have the locating hole when being connected with boring and milling machine main shaft.
Preferably, described installing hole has four.
A kind of boring and milling machine main shaft drill holder described in the utility model, it is the equal of the translation interface of main shaft specification, original tooling system also can directly be used and not need the large-scale cutter of custom-made, shortened the supporting cycle of instrument, can utilize to greatest extent standard cutter, reduce use cost; Can directly use the cutter on middle-size and small-size lathe, not needing often all will increase cutter spacer shell and affect precision, alleviated tool weight simultaneously, reduced labor strength, improved operating efficiency, client effectively utilized existing tooling system, for can save a large amount of cutter use costs.
Accompanying drawing explanation

Fig. 2 is the utility model integral installation schematic diagram
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, to make those skilled in the art can implement according to this with reference to description word.
As shown in Figure 1, Fig. 2, shown in the utility model a kind of boring and milling machine main shaft drill holder is provided, comprising:
Main body 1, described main body 1 is divided into the first half 2 and Lower Half 3, and the first half 2 has the first endoporus 4, and described the first endoporus 4 is conical, and aperture one end of the first endoporus is welded with the Lower Half with conical external surface; Described Lower Half has the second endoporus 5; Pulling claw 6, is installed in main body Lower Half the second endoporus 5, and pulling claw 6 one end are for fixed cutting tool, and the other end is arranged on the top of blind rivet 7; Blind rivet 7, is provided with back-moving spring 8 on the axle of described blind rivet 7.
Further in main body, have the installing hole 10 for being connected with boring and milling machine main shaft.
In further described main body, be provided with for limiting the locating piece 11 of tool position.
In further described main body, have the locating hole 12 when being connected with boring and milling machine main shaft.
During use, the Lower Half 3 that boring and milling machine main shaft drill holder has conical external surface feed in the taper circular hole of boring and milling machine main shaft 13, for limiting the spacing position that packs boring and milling machine main shaft in the locating hole 12 of boring and milling machine main shaft drill holder position into, then lock screw is inserted to installing hole 10, with nut, fix.Cutter 9 is fit in taper first endoporus 4 of boring and milling machine main shaft drill holder to the in-built locating piece 11 that enters boring and milling machine main shaft drill holder in spacing position on cutter 9.Start boring and milling machine device, blind rivet 7 will up be drawn, and drives pulling claw 6, and pulling claw 6 middle parts are drawn close to center, with this, tightly holds onto cutter.When not using cutter, blind rivet 7, by depress, makes pulling claw 6 middle parts to unclamping, and cutter can be taken off easily, and in the time of when the strength of the nail of push-and-pull instantly 7 loses, thereby back-moving spring will up push up blind rivet 7 to make blind rivet 7 get back to original position.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in description and embodiment, it can be applied to the various fields of the present utility model that are applicable to completely, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend of describing.
