Description

A Turning Tool Used for Flat End Face and Chamfering of Round Tube Parts

technical field

Background technique

At present, at least two types of turning tools are required for flattening and chamfering of round tubular parts, as shown in Figure 1 and Figure 2. Then, one turning tool and one lathe are used to flatten the end surface, occupying one station. When chamfering, either change the turning tool or enter the next process; using the method of changing the turning tool wastes time and seriously affects work efficiency; if another process is used, another lathe and another station are required for assembly line processing , not only still wastes time, but also increases equipment cost and labor cost. Therefore, how to provide a turning tool capable of both flat end faces and chamfering is an urgent problem to be solved by those skilled in the art. .

Preferably, in the above technical solution, a blade with a flat end face is installed in the middle of the cutter head, and a triangular blade is installed on both sides of the blade with a flat end face.

Preferably, in the above technical solution, the flat-end insert is a triangular insert, and the angle that its cutting edge subtends is the included angle between the two hypotenuse cutting edges of the triangular insert.

Preferably, in the above-mentioned technical solution, a flat end blade is installed on one side of the cutter head, and a triangular blade is installed on the other side, and the supplementary angle of the included angle between the two hypotenuse cutting edges and the bottom edge of the triangular blade is the processed Chamfer angle.

Compared with the prior art, the utility model has the beneficial effects of:

The utility model provides a turning tool for the flat end face and chamfering of round tubular parts, which integrates the functions of flat end face and chamfering, and realizes the flat end face and chamfering of round tubular parts with one lathe and one worker. The machining process of end face and chamfering not only reduces the time for changing turning tools, but also reduces one process, which greatly saves processing time, saves processing equipment costs and labor costs, and improves work efficiency.

Detailed ways

Example 1:

As shown in Figure 3, a turning tool used for flat end faces and chamfering of round tubular parts includes a handle 1, the front end of the handle 1 is provided with a cutter head 2, and a flat end face blade 3 is installed in the middle of the cutter head 2. A triangular blade 4 is respectively installed on both sides of the end face blade 3, and among the two hypotenuses of one corner of the two triangular blades 4, the hypotenuse near the flat end blade 3 is the cutting edge, and the angle between the bevel and the flat end blade 3 cutting edges is the processed The chamfering angle of the flat end face insert 3 is a triangular insert, and the angle to which its cutting edge is opposite is the angle between the two hypotenuse cutting edges of the triangular insert 4.

When using the turning tool for the flat end face and chamfering of round tubular parts provided by the present embodiment, the turning tool is installed on the lathe tool holder, and the flat end face blade 3 is aligned with the flat end face of the machined part 5 for cutting; the cutting is completed Finally, move the tool rest forward until the triangular blade 4 contacts the outer edge of the processed part 5 to realize chamfering the outer corner; then move the tool rest backward until another triangular blade 4 contacts the inner edge of the processed part 5 to realize chamfering the inner corner.

Example 2:

As shown in Figure 4, the turning tool for the flat end face and chamfering of round tubular parts provided by this embodiment includes a handle 1, a cutter head 2 is provided at the front end of the handle 1, and a flat end face is installed on one side of the cutter head 2 The other side of the blade 3 is equipped with a triangular blade 4, and the supplementary angle of the included angle between the two hypotenuse cutting edges of the triangular blade 4 and the bottom edge is the processed chamfering angle.

When using the turning tool for the flat end face and chamfering of round tubular parts provided by the present embodiment, the turning tool is installed on the lathe tool holder, and the flat end face blade 3 is aligned with the flat end face of the machined part 5 for cutting; the cutting is completed Finally, move the tool rest forward until the first hypotenuse of the triangular blade 4 touches the inner edge of the processed part 5 to realize chamfering; move the tool rest backward until the second hypotenuse of the triangular blade 4 contacts the outside of the processed part 5 edge, to realize the chamfering of the outer corner; when the inner and outer chamfering angles of the processed part 5 are the same, the same bevel can be used to realize the chamfering.
