Description

Deep hole turning tool

technical field

The utility model relates to a deep hole turning tool. the

Background technique

The machining of shaft and hole parts on the CA6140 lathe is basically carried out with ordinary turning tools. But when it comes to processing deep-hole parts, it is difficult for these ordinary turning tools to complete the cutting task at one time, because a large amount of cutting heat will be generated during the cutting process, and the coolant cannot flow to the cutting place, and the cutting heat will be transferred to the In the cutting tool and the workpiece, it will affect the durability of the tool and the dimensional accuracy of the hole; and the edge inclination and auxiliary relief angle of ordinary turning tools are a fixed value, and the edge inclination and auxiliary relief angle cannot be changed at any time during the cutting process. Control the outflow direction of chips (changing edge inclination angle) and the friction with the machined surface (sub-relief angle); and during the cutting process, chips cannot be removed from the air in time, which will affect the roughness. All of the above reasons will affect the service life of the tool and the improvement of the machining accuracy of the workpiece. the

Contents of the invention

In order to solve the problems of affecting the service life of the tool and low machining accuracy of the workpiece when the common turning tool is used for processing deep hole parts, the utility model provides a deep hole turning tool with a long service life and high machining accuracy of the workpiece. the

The technical scheme of the utility model:

The deep hole turning tool is characterized in that: it includes a circular cutter bar, the front end of the circular cutter bar is welded with a circular cutter head, the circular cutter bar is a hollow structure, and the inner hole of the circular tool bar Connected to the circular cutter head. the

Further, the circular cutter head is a hard alloy circular cutter head. the

The working process of the utility model: during the processing, the hose nozzle is inserted into the inner hole of the circular cutter rod, so that the cooling liquid can be poured directly to the cutting place, so that the cutting heat is taken away by the cooling liquid in time, and the cutting heat is removed from the deep hole. The outflow reduces the temperature of the tool and improves the durability of the tool. At the same time, chips will also be discharged from the deep hole along with the coolant; in order to control the direction of chip flow, as long as the tool is rotated, the blade inclination angle on the circular cutter head will change, and at the same time, the secondary relief angle on the tool will also change, directly The friction with the machined surface is changed, thereby improving the machining accuracy and surface roughness of the workpiece. the

The intended effect of the utility model is that the durability of the tool is improved, chips can be discharged in time, and the machining accuracy and surface roughness of the workpiece are improved. the

Detailed ways

Referring to Figures 1-4, the deep hole turning tool includes a circular cutter bar 1, the front end of the circular cutter bar 1 is welded with a circular cutter head 2, the circular tool bar 1 is a hollow structure, and the circular The inner hole 3 of the shaped cutter bar 1 communicates with the circular cutter head 2. the

The circular cutter head 2 is a carbide circular cutter head. the

The working process of the utility model: during the processing, the hose nozzle 4 is inserted into the inner hole 3 of the circular cutter bar 1, so that the cooling liquid can be directly poured into the cutting place, so that the cutting heat is taken away by the cooling liquid in time, from The outflow from the deep hole reduces the temperature of the tool and improves the durability of the tool. At the same time, the chips will also be discharged from the deep hole along with the coolant; in order to control the flow direction of the chips, as long as the tool is rotated according to the arc arrow shown in Figure 4, the blade inclination angle on the circular cutter head 2 will change, and at the same time The secondary relief angle on the tool will also change, which directly changes the friction with the machined surface, thereby improving the machining accuracy and surface roughness of the workpiece. the

The content described in the embodiments of this specification is only an enumeration of the realization forms of the utility model concept, and the protection scope of the utility model should not be regarded as being limited to the specific forms stated in the embodiments, and the protection scope of the utility model also includes Equivalent technical means that those skilled in the art can think of according to the concept of the utility model. the
