Description
Technical Field
The utility model relates to a lathe tool technical field specifically is a lathe double knives head combination lathe tool structure.
Background
At present, when a common lathe is used for processing an inner cavity of a shell, a lathe bar with a common lathe inner hole lathe tool is needed for processing; when the outer circle of the car is required to be changed, the turning tools are all single tool bits. For some thin-wall shell parts, the outer circle and the inner cavity cannot be turned independently during turning, and the turning should be performed alternately and uniformly to reduce the deformation of the shell. Thus, the turning tool needs to be frequently replaced to meet the machining requirement. However, such an operation has the following problems: a. the tool is frequently changed, so that the processing efficiency is greatly reduced; b. due to frequent tool changing, tool mounting and tool setting errors exist, so that the precision of the machined part is low; c. the service life of the cutter bar tool-loading groove is reduced due to frequent cutter changing.
SUMMERY OF THE UTILITY MODEL
The utility model discloses aim at solving the current technical problem who needs frequent tool changing when using single knife tool bit lathe tool processing thin wall casing part inner chamber and excircle. Therefore, the utility model provides a double-cutter combined turning tool structure body of a common lathe.
The utility model provides a technical scheme that its technical problem adopted is:
ordinary lathe double knives head combination lathe tool structure, including ordinary lathe hole lathe tool and lathe tool pole, ordinary lathe hole lathe tool includes cylindrical cutter body, the one end of cutter body is equipped with the hole tool bit, the hole tool bit can be dismantled and be fixed with hole blade (can dismantle the change that makes things convenient for hole blade), the middle part of cutter body with lathe tool pole can be dismantled fixedly (the change of making things convenient for the lathe tool), the other end of cutter body has increased excircle tool bit, the lathe tool groove has been seted up on the excircle tool bit, lathe tool groove embedded is equipped with excircle blade and through screw locking (excircle tool bit, lathe tool groove and excircle blade body design adopt what kind of structure, this is that the easy design of the personnel in the machining field, and this is not repeated here.
The utility model has the advantages that:
1) the effect of uniformly turning the outer circle and the inner cavity of the shell by clamping the turning tool at one time is realized, the tool changing time is saved, and the machining efficiency is improved;
2) the tool changing error caused by tool changing is reduced, and the processing precision of the outer circle and the inner cavity of the shell is improved;
3) the tool changing times are reduced, and the service life of the tool bar is prolonged;
4) the structure body is reformed on the basis of an original lathe inner bore turning tool, the existing structure is utilized, the whole tool does not need to be completely redesigned, the reforming cost is lower, and the practicability is higher.
