Further optimization: The cutter body is a long strip structure with a rectangular cross-section, which matches the joint surface of the tool handle of the machine tool and facilitates the installation of the cutter body.

Further optimization: the position between the left support part and the right support part on the cutter body is processed with a circular through hole perpendicular to the horizontal plane of the cutter body and a straight groove connected to it. connected through holes.

The section width of the straight groove is the distance between the left support part and the right support part.

The above scheme makes the left support part and the right support part integrally connected with the cutter body, enhances the connection strength of the left support part and the right support part, and makes a certain adjustment distance between the left support part and the right support part. the

Further optimization: the diameter of the circular through-hole is greater than the cross-sectional width of the straight slot.

When the distance between the left supporting part and the right supporting part is adjusted, it is convenient to buffer and disperse the tensile force and compressive force generated by the root to prevent the root from breaking.

Further optimization: the front ends of the left support part and the right support part are respectively processed with symmetrically distributed blade installation grooves, and threaded holes with chamfers are processed in the installation grooves, and the indexable blades of the machine clamp are fixed with compression screws through the threaded holes In the blade installation groove, it is convenient to install and adjust the angle of the indexable blade of the machine clamp.

Further optimization: The adjustment device consists of a locking bolt mounted on one side of the cutter body and two tensioning screws mounted on the other side of the cutter body.

The head of the locking bolt is located in the left support part, and the screw part passes through the straight groove and is threadedly connected with the right support part.

The tensioning screw is threadedly connected with the right supporting part, and a cylindrical pad is installed on the left supporting part at a position corresponding to the bottom of the tensioning screw.

If the cutting width is smaller than the specified size after the blade is worn, loosen the locking bolt slightly first, tighten the two tensioning screws so that the turning width reaches the specified size requirement, and finally tighten the locking bolt;

If the turning width may be larger than the specified size when replacing a new blade, first slightly loosen the tension screw, tighten the locking bolt to make the turning width meet the specified size requirement, and finally tighten the tension screw.

The present invention adopts the above scheme. When processing, the workpiece to be processed is first fixed on the fixture installed on the rotary spindle of the lathe, and the two indexable blades of the machine clamp are respectively installed on the left support part and the right support part of the cutter body. The rotation of the locking bolt and the tensioning screw adjusts the turning width of the double-edged end face turning tool to the size specified in the drawings and process documents, and then the turning process can be carried out.

The double-edged end face turning tool manufactured by the present invention adopts the above-mentioned scheme. During processing, both sides of the open crotch of the workpiece can be processed at one time. At the same time, because the cutting width can be adjusted, it can meet the processing size and shape tolerance requirements, greatly improving the work efficiency, and at the same time Can reduce workpiece processing cost.

The present invention will be further described below in conjunction with drawings and embodiments.
