Abstract

The invention discloses a tool bar for turning deep tapered holes, which comprises a tool bar body and a tool head. The longitudinal section of the tool bar body is tapered. One end of the tool bar body is a large-diameter end, and the other end is a small-diameter size end. end; the cutter head is detachably connected to the small diameter end of the cutter body. The longitudinal section of the cutter bar of the present invention is tapered, the radial size of the cutter bar body is from large to small, and the strength of the cutter bar body is higher than that of the radially consistent size cutter bar, so it is not easy to shake during the process of machining deep tapered holes. It is also not easy to be damaged, has high processing precision and long service life. The cutter head can be replaced according to processing needs, which improves the utilization rate and reduces production costs.

Description

A Tool Arbor for Turning Deep Tapered Holes

technical field

The invention relates to a cutter bar capable of processing deep taper holes, high in strength, good in processing precision and high in utilization rate.

Background technique

In machining, when processing deep tapered holes, most of them use the traditional tool holder with the same radial size. Since the diameter of the deep tapered hole is changed from large to small, the radial direction of the traditional tool holder is limited. The size cannot be larger than the minimum aperture size of the deep taper hole, which leads to a small radial dimension of the tool holder. During the processing of the deep tapered hole, the tool holder is prone to vibration, which reduces the machining accuracy, and the radial size of the tool holder is small, and the length If it is too long, the tool holder is easily damaged during processing, which reduces the service life.

Contents of the invention

In view of the above-mentioned technical problems, the object of the present invention is to propose a tool holder capable of processing deep taper holes, with high strength, good machining accuracy and high utilization rate.

In order to achieve the above object, the technical solution adopted in the present invention is: a tool bar for turning deep tapered holes, comprising a tool bar body and a cutter head, the longitudinal section of the tool bar body is conical, and one end of the tool bar body is a large diameter end, and the other end is a small diameter end; the cutter head is detachably connected to the small diameter end of the cutter body.

Preferably, the cutter head is a boring cutter or a threading cutter or a grooving cutter.

Due to the application of the above-mentioned technical solution, the present invention has the following advantages compared with the prior art:

A tool bar for turning deep taper holes according to the present invention, the tool bar section is conical, the radial size of the tool bar is from large to small, and the strength of the tool bar body is higher than that of the radially consistent size tool bar, so It is not easy to shake and damage during the processing of deep tapered holes, with high processing precision and long service life. The cutter head can be replaced according to processing needs, which improves the utilization rate and reduces production costs.

Description of drawings

Below in conjunction with accompanying drawing, technical solution of the present invention will be further described:

Accompanying drawing 1 is the structural representation of the cutter bar that a kind of turning deep taper hole of the present invention is used;

Accompanying drawing 2 is the structural representation that a kind of cutter bar and deep taper hole cooperation of a kind of turning deep taper hole of the present invention are used;

Among them: 1. Cutter body; 2. Cutter head; 3. Large diameter end; 4. Small diameter end; 5. Deep taper hole.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Accompanying drawing 1-2 is the cutter bar that a kind of turning deep tapered hole of the present invention is used, comprises cutter holder body 1 and cutter head 2, and described cutter holder body 1 longitudinal section is conical, and the section of cutter holder body 1 The shape can be conical, pyramidal or truncated conical prism; one end of the tool holder body is a large diameter end 3, and the other end is a small diameter end 4; the radial dimension of the small diameter end 4 is smaller than that of the deep cone. The minimum aperture size of the hole 5; the cutter head 2 is detachably connected to the small diameter end 3 of the cutter bar body 1; because the cutter bar body 1 section is similar to the shape of the deep taper hole 5, from thick to thin, the cutter bar body 1 The strength is better than the traditional tool holder with the same radial dimension. When processing deep tapered holes, the tool holder body 1 is not easy to shake or be damaged, which improves the machining accuracy. The cutter head 2 is a boring cutter, thread cutter or grooving cutter; it can be used as required Replace the cutter head 2, improve the utilization rate of the cutter rod, and save production costs.

The above-mentioned embodiments are only to illustrate the technical conception and characteristics of the present invention. Substantial equivalent changes or modifications shall fall within the protection scope of the present invention.
