Abstract
The invention belongs to the field of aviation gear shafts, and particularly relates to a boring cutter special for turning grooves in aviation gear shaft parts. Comprises a cutter bar, a cutter head, a positioning screw and a locking screw; the front part of the cutter bar is provided with a mounting hole, a positioning hole and a fixed locking hole of the cutter head, and the cutter head is fixed by a positioning screw and a locking screw through the mounting hole on the cutter bar. The turning processing of the grooves in the aviation gear shafts is realized, so that a cutter is prevented from being equipped for processing the grooves in each gear shaft, and a large amount of part processing time is saved. The overhanging size of the cutter head is adjusted, so that grooves in gear shafts with different sizes can be machined on the premise of not changing cutters, and the multipurpose cutter is realized. The cutter bar is made of 40Cr material, so that the comprehensive performance of the material is excellent, and the cost is low; the gear shaft is made of 30CrMnSiA and the hardness is HRC35, so the cutter head is formed by grinding integral hard alloy, the coating of the cutting edge is treated, and the cutter has good wear resistance.
Description
Technical Field
The invention belongs to the field of aviation gear shafts, and particularly relates to a boring cutter special for turning grooves in aviation gear shaft parts.
Background
At present, turning is mainly used in the processing of grooves in gear shafts, firstly, because the material of gear shaft parts is mostly 30CrMnSiA, the hardness is about HRC35, and the processing process is intermittent processing, the requirement on the strength of a cutter is higher; secondly, the groove in the gear shaft is generally deeper from the end face, the cutting amount is large, the suspension of a cutter is large in the machining process, the requirement on the rigidity of the cutter is high, a special boring cutter for cutting machining is not arranged, a self-made forming cutter is generally adopted for machining, but the cutter is quickly worn and needs to be repeatedly ground, and the machining efficiency is low; thirdly, because the gear shaft parts have similar structures and the sizes of the inner grooves have little difference, the boring cutter can be designed and optimized in a targeted manner, and the processing efficiency is improved. The invention can effectively solve the problems of the grooves in the gear shaft parts in the processing process, and can be used for processing other deep cavity grooves.
Disclosure of Invention
Technical scheme
The invention aims to provide a special boring cutter for turning grooves in aviation gear shaft parts.
The above purpose is realized by the following technical scheme:
a special boring cutter for turning an inner groove of an aviation gear shaft part comprises a cutter bar 1, a cutter head 4, a positioning screw 2 and a locking screw 3; the front part of the cutter bar 1 is provided with a mounting hole, a positioning hole and a fixed locking hole of the cutter head 4, and the cutter head 4 is fixed by a positioning screw 2 and a locking screw 3 through the mounting hole on the cutter bar 1.
Technical effects
1. The invention realizes the turning of the inner groove of the aviation gear shaft, thereby avoiding the arrangement of a cutter for the processing of the inner groove of each gear shaft and saving a large amount of part processing time.
2. The cutter head overhanging size designed by the invention can be adjusted, and the grooves in gear shafts with different sizes can be processed on the premise of not changing cutters, so that the cutter head is multipurpose.
3. The cutter bar is made of 40Cr material, so that the comprehensive performance of the material is excellent, and the cost is low; the gear shaft is made of 30CrMnSiA and the hardness is HRC35, so the cutter head is formed by grinding integral hard alloy, the coating of the cutting edge is treated, and the cutter has good wear resistance.
