CN212121696U - An indexable turning tool that can mount different types of inserts - Google Patents

Abstract

The utility model discloses an indexable turning tool capable of installing different types of inserts, comprising a cross-shaped key, a cutting head, a cutting blade, a cutting shank, a cutting groove, a cutting head fixing bolt and a cutting blade clamping screw. The blade is fixed to the cutter head through a cross-shaped key and is fixed to the cutter head fixing bolt, and the blade is fixed to the cutter groove through the blade clamping screw. In the utility model, the cutter head is provided with a different type of cutter groove at an interval of 45°. When it is necessary to replace blades with different geometric angles, it is only necessary to unscrew the cutter head fixing bolt after the cutter head is removed to change the matching angle between the cutter head and the cutter bar. , and then install the blade without replacing the tool holder; when the tool head containing these four insert grooves cannot meet the processing requirements, the tool head can also be removed and replaced.

Description

An indexable turning tool that can mount different types of inserts

technical field

The utility model relates to a metal cutting tool, in particular to an indexable turning tool.

Background technique

The indexable turning tool is formed by mechanically clamping the indexable carbide insert on the arbor. The insert has geometric parameters for cutting and more than three cutting edges for indexing. After the cutting edge is worn out, loosen the clamping mechanism, transfer the insert to another cutting edge and then clamp it, then cutting can be performed. Its unique advantages and the gradual maturity of technology in recent years, its application has become more and more extensive; in the existing machining using indexable turning tools, one type of indexable turning inserts can only be installed in When using other types of indexable inserts on the matching type of kerf, it is necessary to replace the matching tool head at the same time, and to change the geometric angle of the insert, it is also necessary to replace the matching tool head; One is that the current tool head and the tool holder are one-piece structure. If one type of insert corresponds to one type of tool head, it will cause waste of resources when manufacturing indexable turning tools; from the manufacturer's point of view , if one type of cutter head can only correspond to one type of blade continuously, it will increase the production cost and reduce the production efficiency.

SUMMARY OF THE INVENTION

In view of the above situation, the utility model proposes an indexable turning tool that can be installed with different types of blades, and one tool head can be installed with a variety of different types of blades, which improves efficiency and saves costs.

Technical solutions

In order to achieve the above purpose, the utility model provides the following technical solutions: an indexable turning tool that can be installed with different types of blades, including a cross-shaped key, a cutter head, a blade, a cutter bar, a cutter groove, a cutter head fixing bolt, and a blade clamp Tighten the screw, the cutter head and the cutter shank are fixedly connected with the cutter head fixing bolt through the cross-shaped key, and the blade is fixed to the cutter groove by the blade clamping screw.

beneficial effect

Compared with the existing indexable turning tool, the beneficial effect of the utility model is that the tool head is provided with different types of tool grooves every 45°, and the tool can be selected and used by changing the matching angle of the cross-shaped key between the tool head and the tool body. Different types of inserts, so that various types of inserts can be installed on one cutter head. When processing needs to use different types or different geometric angles of inserts, we only need to change the matching angle between the cutter head and the shank. , and then the cutter head can be replaced, the operation is convenient, the clamping time is reduced, the work efficiency is improved, and the tool cost is saved.

Cross key (1), cutter head (2), blade (3), cutter shank (4), cutter head fixing bolt (5), cutter groove (6), blade clamping screw (7).

Detailed ways

The present utility model will be further described below with reference to the accompanying drawings. The following examples are used to illustrate the technical solutions of the present invention more clearly, but cannot be used to limit the protection scope of the present invention.

Example 1: As shown in Figures 1, 2, and 3, a cutter head (2) and a cutter shank (4) of an indexable turning tool that can install different types of blades are connected to the cutter head fixing bolts through a cross-shaped key (1). (5) fixed; insert (3) is fixed by insert clamping screw (7).

Example 2: The described indexable turning tool that can be installed with different types of inserts, by changing the angle of the cross-shaped key between the tool head and the tool shank, the tool head has different types of kerfs every 45 degrees, and then Switch to use blades of different angles, so that by changing different grooves, one cutter head can be installed with multiple types of blades. The equilateral triangle blade is installed in Figure 4, the 75° diamond blade is installed in Figure 5, and the 30° diamond blade is installed in Figure 6.

It can be seen from the above textual expression that the use of this indexable turning tool that can install different types of inserts, compared with the traditional indexable turning tool, uses the cross-type key to connect the tool head and the tool holder. °Set a knife groove to achieve the purpose of replacing the blade by changing the matching angle of the knife head and the knife shank, which saves the clamping time of the knife shank and the use of materials.

In addition to the above-mentioned embodiments, the present invention can also have other implementations, that is, when the four kerfs on one cutter head cannot meet the processing requirements, the cutter head can be removed to replace the cutter head with other types of sipes.
