Abstract

The utility model discloses a cutting tool for processing semi-circular arc holes, which comprises a knife bar and knife grains mounted on the knife bar, the knife grains are fixed in mounting holes of the knife bar through fixing screws, and the cutting tool is characterized in that a plurality of the mounting holes for the knife grains are formed on the knife bar; and regulating screws capable of regulating extension amount of the knife grains are arranged in the mounting holes for the knife grains on the knife bar. The cutting tool can simultaneously process a plurality of coaxial semi-circular arc holes once, the diameter of the arc holes and the depth of the arc holes in inner holes of a workpiece can be adjusted, and the processing precision and the production efficiency are significantly improved. The cutting tool is applicable to the related machining field.

Description

The process tool in the bent hole of a kind of semicircle

Technical field

The utility model relates to a kind of machining tool, the dedicated tool of the bent hole processing of especially a kind of semicircle usefulness.

Background technology

In machine tool mechanical processing, usually need process the semicircle or the bent hole of arc of several different-diameters at the side surface of workpiece endoporus.These bent holes have alignment but the internal diameter difference, form a special cavity with the workpiece endoporus, processing request precision height, and difficulty is big.

Traditional processing is with the different cutters of diameter first circular port of processing work successively.So once only process a sector hole, waste time and energy, and repeatedly tool changing back and forth, be difficult to guarantee the alignment precision in each hole.

When the semicircle orifice on the endoporus was symmetrical up and down, conventional method was to use index dial that workpiece is turned over turnback and finishes the processing of symmetrical structure up and down.But be difficult to satisfy the requirement of axiality and production efficiency.

The utility model content

The purpose of this utility model is to provide a kind of process tool in the bent hole of workpiece endoporus processing semicircle,

This cutter can a plurality of different inner diameters of time processing the bent hole of coaxial semicircle.

The technical solution of the utility model comprises:

The process tool in the bent hole of a kind of semicircle comprises knife bar and the cutter grain that is installed on the knife bar, and described cutter grain is fixed in the installing hole of described knife bar, wherein by hold-down screw: described knife bar is provided with the installing hole of the described cutter grain of a plurality of installations.

The process tool in the bent hole of described semicircle, wherein: the cutter grain installing hole of described knife bar is provided with the adjustment screw that can regulate cutter grain overhang.

The technique effect that the utility model produces is: owing to be provided with a plurality of apart from the adjustable cutter grain of cutter spindle centre distance at the diverse location of a knife bar, realized once can processing simultaneously the bent hole of a plurality of coaxial semicircles, diameter and the bent hole degree of depth in the workpiece endoporus in bent hole all can be adjusted, and has significantly improved machining accuracy and production efficiency.

Description of drawings

Fig. 1 is the bent aperture knife tool structural representation of the utility model semicircle.

The specific embodiment

Below in conjunction with accompanying drawing embodiment, illustrate that structural principle of the present utility model is as follows:

As shown in Figure 1, the bent aperture knife tool structure of the utility model semicircle comprises knife bar 1, cutter grain 2, and cutter grain 2 is installed in the installing hole on the knife bar 1, and is fixing by hold-down screw 3.

Knife bar 1 of the present utility model is provided with a plurality of installing holes, can install and fix a plurality of cutter grains 2, and by the distance of each cutter grain 2 of change between installing hole, controls and respectively process the degree of depth of bent hole in the workpiece endoporus.

Another feature of the present utility model is that installing hole is provided with the adjustment screw that can regulate cutter grain emersion amount, by adjustment screw, can change the distance of cutter grain 2 apart from knife bar 1 central shaft, and then changes the diameter in the bent hole of processing semicircle.

In sum, architectural feature of the present utility model has guaranteed to realize once can processing the bent hole of a plurality of semicircles, and the degree of depth in the bent hole of semicircle and the purpose that diameter can be adjusted have improved machining accuracy and production efficiency.

Should be understood that above-mentioned description at specific embodiment is comparatively detailed, can not therefore think the restriction to the utility model scope of patent protection, scope of patent protection of the present utility model should be as the criterion with claims.

Claims

1. the process tool in the bent hole of semicircle comprises knife bar and the cutter grain that is installed on the knife bar, and described cutter grain is fixed in the installing hole of described knife bar by hold-down screw, it is characterized in that: described knife bar is provided with the installing hole of the described cutter grain of a plurality of installations.

2. the process tool in the bent hole of semicircle according to claim 1, it is characterized in that: the cutter grain installing hole of described knife bar is provided with the adjustment screw that can regulate cutter grain overhang.
