Abstract
The utility model discloses a diameter-varying sleeve. The diameter-varying sleeve comprises a diameter-varying sleeve body, wherein a limiting protrusion is arranged at one end of the diameter-varying sleeve body, the limiting protrusion is in an annular structure, clamping holes are arranged at one side of the diameter-varying sleeve body, the limiting protrusion is arranged to conveniently determine the position between a knife rest and a diameter-varying sleeve, a chamfer is arranged at the outer side of the diameter-varying sleeve body so that the diameter-varying sleeve is installed conveniently, and a chamfer is arranged at the inner side of the limiting protrusion so that a cutting tool is installed conveniently. The diameter-varying sleeve is matched with the knife rest for use, and therefore the generality of the knife rest can be strengthened, and manufacturing cost is saved.
Description
Technical field
The utility model relates to a kind of machining apparatus servicing unit, relates in particular to a kind of drill holder.
Background technology
In the hole of lathe processing different size or during groove, need to change the cutter of different sizes, and the size of the size of cutter and knife bar is normally corresponding, the size of common knife bar changes when changing cutter, may cause tool rest and knife bar not to mate in by the tool rest mounting cutter, impact is used, and at this moment usually needs to change tool rest, the complicated manufacturing cost of tool-apron structure is high, and the replacing tool rest can strengthen processing cost affects economic benefit.
The utility model content
The technical problem that the utility model solves is: provide a kind of drill holder and tool rest to be used in conjunction with the versatility that improves tool rest.
For reaching this purpose, the utility model by the following technical solutions:
A kind of drill holder comprises the drill holder main body, and described drill holder main body one end is provided with spacing preiection, and described spacing preiection is circulus, and described drill holder main body one side is provided with the clamping hole.
Further, described spacing preiection and drill holder main body are structure as a whole.
Further, the described drill holder main body inside that is provided with spacing preiection one end is provided with the first chamfering.
Further, described drill holder main body has the second chamfering away from the arranged outside of an end of spacing preiection.
Further, described clamping hole is three, along the drill holder body shaft to uniform.
The beneficial effects of the utility model are: the spacing preiection that is provided with simple in structure is convenient to determine position between tool rest and the drill holder, drill holder main body arranged outside has chamfering to be convenient to the installation of drill holder, be provided with the installation that chamfering is convenient to cutter in inboard, spacing preiection place, drill holder and tool rest are used in conjunction with the versatility that can increase tool rest, save manufacturing cost.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the drill holder structural representation.
Fig. 2 is Fig. 1 top view.
Among the figure:
1, drill holder main body; 2, spacing preiection; 3, clamping hole; 4, the first chamfering; 5, the second chamfering.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
As shown in Figure 1, 2, in the present embodiment, a kind of drill holder described in the utility model, it comprises the drill holder main body, and described drill holder main body one end is provided with spacing preiection, and described spacing preiection is circulus, described spacing preiection and drill holder main body are structure as a whole, described drill holder main body one side is provided with the clamping hole, and described clamping hole is three, along the drill holder body shaft to uniform; The inside that described drill holder main body is provided with spacing preiection one end is provided with the first chamfering; Described drill holder main body has the second chamfering away from the arranged outside of an end of spacing preiection.
During work with drill holder in the second chamfering direction is packed tool rest into, until spacing preiection contacts with end surface of knife holder, the rotary variable-diameter cover aligns the installing hole on clamping hole and the tool rest, cutter is fit into drill holder from the first chamfering place, passes installing hole on the tool rest and the clamping hole on the drill holder clamps cutter and cutter bar with the clamping bolt.
Can change the tool rest internal diameter by drill holder is set, make tool rest can adapt to the installation of different cutters, improve the versatility of tool rest, save processing cost, when needs are changed the cutter of different size, only need change drill holder and get final product.
What need statement is; the above-mentioned specific embodiment only is preferred embodiment of the present utility model and institute's application technology principle; in technical scope disclosed in the utility model; the variation that any those skilled in the art of being familiar with easily expected or replacement all should be encompassed in the protection domain of the present utility model.
