Abstract
The utility model relates to a step tool bit for a lathe, and belongs to the technical field of the design of the tool bit on the lathe. The step tool bit for the lathe comprises a cone tool body and is characterized in that at least one tool edge is arranged at the large head end of the cone tool body in an extending mode, the tool edge is of a step type structure, the step height of the tool edge is decreased sequentially from left to right, an oil through thread hole is formed inside the left end of the cone tool bit, an oil hole is formed inside the tool edge, the oil hole is communicated with the right end face of the tool edge, and the oil hole is communicated with the oil through thread hole. The step tool bit for the lathe is simple in structure, and due to the fact that the tool edge of the step type structure is used, a plurality of step holes are machined at one time. When the step tool bit for the lathe is used, according to a workpiece in which the step holes need to be machined, the step-type tool edge corresponding to the workpiece is chosen, the step-type tool edge is mounted on the lathe through the cone tool body, then the oil through thread hole is connected with an oil conveying pull rod, machining work of the step holes can be conducted, time and labor are saved, original machining processes are reduced, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of for the step cutter head on the lathe, belongs to cutter head design field on the lathe.
Background technology
At present, when the workpiece of the many stepped holes of lathe processing, because the blade cutting diameter of cutter head is unique, usually the method for employing is, processes first the first step, machines rear parking, then corresponding second step is changed corresponding cutter head at lathe, process again, the like.Adopt this method adding man-hour, operation is more, because tool changing head repeatedly, probably causes the center, hole of many stepped holes of processing that deviation is arranged, and time-consuming, production efficiency is low.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide that a kind of it is simple in structure for the step cutter head on the lathe, can process by disposable workpiece to many stepped holes, time saving and energy saving, as to have avoided repeatedly the tool changing head to cause hole centre deviation.
Described in the utility model for the step cutter head on the lathe, comprise the cone cutter hub, it is characterized in that: cone cutter hub stub end is extended with at least one blade, blade is staircase structural model, the shoulder height of blade reduces from left to right successively, and cone cutter hub left end inside offers logical whelk pit, offers oilhole in blade inside, oilhole communicates with the blade right side, and oilhole communicates with logical whelk pit.
Adopt the blade of staircase structural model, realized the disposable many stepped holes of processing of finishing.Logical whelk pit is set conveniently is connected with existing oil transportation pull bar, when practical application, can change according to the method for attachment of oil transportation pull bar logical whelk pit, it is matched with the oil transportation pull bar.Oilhole is set is adding man-hour, play the effect that blade is cooled off and lubricates the main channel.According to the workpiece of many stepped holes of required processing, select step blade correspondingly during use, then be installed on the lathe by the cone cutter hub, will lead to again the whelk pit and be connected with the oil transportation pull bar, can carry out the processing work of many stepped holes.
Wherein, logical whelk pit described in the utility model is opened in cone cutter hub left end inner shaft to the center.Convenient processing with being connected of oil transportation pull bar.
For convenient processing, described oilhole is opened in the blade inner shaft to the center.
The preferred described blade of the utility model is four, and is evenly distributed on the circumference of cone cutter hub.During use, symmetry is strong, and working (machining) efficiency is high.
Compared with prior art, the utlity model has following beneficial effect:
By the utility model, it is simple in structure, owing to adopt the blade of staircase structural model, has realized the disposable many stepped holes of processing of finishing.During use according to the workpiece of many stepped holes of required processing, select step blade correspondingly, then be installed on the lathe by the cone cutter hub, to lead to the whelk pit is connected with the oil transportation pull bar again, can carry out the processing work of many stepped holes, time saving and energy saving, reduced original procedure, improved production efficiency.
Description of drawings
Fig. 1 is cross-sectional view of the present utility model;
Fig. 2 is the right TV structure schematic diagram of Fig. 1.
Among the figure: 1, cone cutter hub 2, logical whelk pit 3, oilhole 4, blade.
The specific embodiment
Below the utility model is described in further detail by specific embodiment; but not in order to limit the utility model; all within the present invention spirit and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
As shown in Figure 1 and Figure 2, be used for the step cutter head on the lathe, comprise cone cutter hub 1, cone cutter hub 1 stub end is extended with at least one blade 4, and blade 4 is staircase structural model, and the shoulder height of blade 4 reduces from left to right successively, cone cutter hub 1 left end inside offers logical whelk pit 2, offer oilhole 3 in blade 4 inside, oilhole 3 communicates with blade 4 right sides, and oilhole 3 communicates with logical whelk pit 2.
In the present embodiment, described logical whelk pit 2 is opened in cone cutter hub 1 left end inner shaft to the center; Described oilhole 3 is opened in blade 4 inner shafts to the center; Described blade 4 is four, and is evenly distributed on the circumference of cone cutter hub 1.
According to the workpiece of many stepped holes of required processing, select step blade 4 correspondingly during use, then be installed on the lathe by cone cutter hub 1, will lead to again whelk pit 2 and be connected with the oil transportation pull bar, can carry out the processing work of many stepped holes.
