CN205165923U - Cutter arbor that dark taper hole of turning was used - Google Patents

Abstract

The utility model relates to a cutter arbor that dark taper hole of turning was used, including cutter bar body and tool bit, cutter bar body longitudinal section is the toper, and cutter bar body's one end is big footpath size end, and the other end is path size end, the path size end of connection at cutter bar body can be dismantled to the tool bit. The utility model discloses cutter arbor longitudinal section is the toper, cutter bar body's radial dimension big -endian, and cutter bar body's intensity wants the specific diameter high to the size cutter arbor of unanimity, so in the difficult shake of the in -process of the dark taper hole of processing, also not fragile, the machining precision is high, long service life, the tool bit can be changed according to requirements of the processing, improves the rate of utilization, reduction in production cost.

Description

A kind of knife bar of turning deep taper hole

Technical field

The utility model relates to a kind of deep taper hole of can processing, and intensity is high, good processing accuracy, the knife bar that utilization rate is high.

Background technology

In machined, when processing deep taper hole, most what adopt is the consistent knife bar of traditional radial dimension, because the aperture processing deep taper hole is from large to small, so the radial dimension just limiting traditional knife bar can not be greater than the minimum-value aperture size of deep taper hole, which results in knife bar radial dimension little, in the process of processing deep taper hole, knife bar very easily produces shake, reduces machining accuracy, and knife bar radial dimension is little, length is long, adds man-hour knife bar and also very easily damages, reduce service life.

Utility model content

The utility model object provides a kind of can process deep taper hole to overcome the deficiencies in the prior art, and intensity is high, good processing accuracy, the knife bar that utilization rate is high.

For achieving the above object, the technical solution adopted in the utility model is: a kind of knife bar of turning deep taper hole, comprises cutter bar body and cutter head, and described cutter bar body longitudinal cross-section is taper, and one end of cutter bar body is large footpath size end, and the other end is path size end; Described cutter head is detachably connected on the path size end of cutter bar body.

Preferably, described cutter head is boring cutter or screwer or grooving cutter.

Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:

The knife bar of a kind of turning deep taper hole of the utility model scheme, knife bar cross section is taper, the radial dimension of knife bar is descending, and the intensity of cutter bar body wants specific diameter high to consistent size knife bar, so not easily shake in the process of processing deep taper hole, not fragile yet, machining accuracy is high, long service life, and cutter head can be changed according to processing needs, improve utilization rate, reduce production cost.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:

Accompanying drawing 1 is the structural representation of the knife bar of a kind of turning deep taper hole of the present utility model;

Accompanying drawing 2 is the structural representation that the knife bar of a kind of turning deep taper hole of the present utility model coordinates with deep taper hole;

Wherein: 1, cutter bar body; 2, cutter head; 3, large footpath size end; 4, path size end; 5, deep taper hole.

Detailed description of the invention

Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.

Accompanying drawing 1-2 is the knife bar of a kind of turning deep taper hole described in the utility model, comprises cutter bar body 1 and cutter head 2, and described cutter bar body 1 longitudinal cross-section is taper, and the cross sectional shape of cutter bar body 1 can be conical, the shapes such as pyramid or circular cone prismatic table shape; One end of cutter bar body is large footpath size end 3, and the other end is path size end 4; The radial dimension of described path size end 4 is less than the minimum-value aperture size of deep taper hole 5; Described cutter head 2 is detachably connected on the path size end 3 of cutter bar body 1; Due to the shape approximation of cutter bar body 1 cross section and deep taper hole 5, from coarse to fine, traditional knife bar that the strength ratio radial dimension of cutter bar body 1 is consistent will be got well, and during processing deep taper hole, cutter bar body 1 is not easily shaken or damages, improve machining accuracy, described cutter head 2 is boring cutter or screwer or grooving cutter; Cutter head 2 can be changed as required, improve knife bar utilization rate, save production cost.

Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
