Embodiment 1

[0018] Combined turning tools include turning tools, tool holders and fastening screws (see figure 1 , figure 2 ), there are 3 square holes processed on the tool holder, which are arranged in a staggered upper and lower angle (see image 3 , Figure 4 , Figure 5 ). Clamp 3 turning tools in the square hole, the extension line of the blade of each turning tool points to the center of the workpiece, and the blade inclination angle is 0 degrees; the difference between the tip of adjacent turning tools and the center of the workpiece is 5mm, that is, the difference in machining radius is 5mm; the axis of adjacent turning tools The direction difference is 3 mm, that is, after the first turning tool cuts the axial length of 3 mm, the second turning tool enters the cutting again, and the cutting sequence is turning tool 1, turning tool 2, and turning tool 3.

[0019] The tool divides the original cutting depth into three, the cutting speed can be increased by more than 50%, and ...

Embodiment 2

[0021] There are 10 square holes processed on the combined turning tool holder, which are distributed in a staggered upper and lower angle. Hold 10 turning tools on the tool holder (see Image 6 , Figure 7 ), the extension line of each turning tool blade points to the center of the workpiece circle, and the blade inclination angle is 0 degrees; the machining radius difference of adjacent turning tools is 2.5 mm, and the axial difference is 2 mm. The cutting order is turning tool 1, turning tool 2, turning tool 3 To turning tool 10.

[0022] This combined turning tool can be used when machining super-large-diameter outer circles. The tool can decompose the original cutting depth into 10 small cutting depths, and the cutting speed can be increased by 200%, which greatly improves the processing efficiency.

Embodiment 3

[0024] Figure 8 Figure 9 It is a combined turning tool for rough turning inner holes. Three turning tools are clamped on the tool holder, the extension line of each turning tool edge points to the center of the workpiece, and the blade inclination angle is 0 degrees; the difference between the machining radius of adjacent turning tools is about 2mm, and the axial difference is 2mm, that is, the first turning tool cuts 2mm After the axial length, the second turning tool enters the cutting again, and the cutting sequence is turning tool 1, turning tool 2, and turning tool 3.

[0025] The cutting depth of each turning tool of the cutting tool is one-third of that of one cutting tool, the cutting speed can be increased by more than 50%, and chips can be easily broken, and the cutting efficiency is obviously improved.

[0026] The number of combined turning tools for roughing the inner hole can also be more than three. When actually machining the inner hole, the number of turni...

Abstract

The invention discloses a combined turning tool and relates to rough turning tools used for cutting inner circles and outer circles at a high speed in the machining industry. 3-10 turning tool bodies are clamped on the turning tool. The extension line of the cutting edge of each turning tool body points to the circle center of a workpiece, and the tool cutting edge inclination angle is 0 degree. Every two adjacent turning tool bodies are staggered by 2-5 mm in the radial direction and staggered by 1-4 mm in the axial direction. The turning tool bodies are ordinary turning tool bodies or mechanically-clamped turning tool bodies. An original cutting depth is divided into 3-10 small cutting depths through the combined turning tool, and the cutting speed can be increased by 50%-200%. By means of the combined turning tool, the defect that in the prior art, cutting can only be conducted at an intermediate speed or a low speed during rough turning of a tool is overcome, and the machining efficiency is greatly improved. The combined turning tool is simple in structure, easy to manufacture, low in price, economical, practical, convenient to use, safe, reliable and not prone to elimination. The market demand for the combined turning tool is large, and the economic benefits and the social benefits are remarkable; in addition, the investment is small, the yield can be obtained rapidly, and the cost can be recovered with a few months.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a combined turning tool for rough machining inner and outer circles, and belongs to the technical field of machining tools. Background technique [0002] Large-scale horizontal lathes and vertical lathes often process some large-diameter workpieces. The machining allowance of these workpieces is as high as more than 100 millimeters. During rough turning, a turning tool is used for cutting, and the cutting depth is usually about 20 to 30 millimeters. Because the cutting speed is inversely proportional to the cutting depth, when the cutting depth is large, only medium and low speed cutting can be selected, so the processing efficiency is low, time-consuming and labor-intensive when rough machining inner and outer circles. Therefore, it is extremely necessary to provide a rough machining inner and outer circular cutting tool with fast cutting speed and high processing efficiency. Contents of the ...
