Abstract
The utility model provides a drilling tool of a thin-walled part. The drilling tool of the thin-walled part comprises a toolbar body and a drilling blade, and is characterized by further comprising an upper chamfering edge and a lower chamfering edge, the upper end of the upper chamfering edge is connected with the toolbar body, the lower end of the upper chamfering edge is connected with the upper end of the lower chamfering edge, the lower end of the lower chamfering edge is connected with the drilling blade, the diameter of the drilling blade is bigger than the diameter of the lower end of the upper chamfering edge, and is smaller than the diameter of the upper end of the upper chamfering edge, and the shape of the lower end of the upper chamfering edge is identical to the shape of the upper end of the lower chamfering edge. The drilling tool of the thin-walled part has the advantages that the upper chamfering edge and the lower chamfering edge are added based on an existing drilling tool, and the drilling tool of the thin-walled part can complete part drilling and two-sided chamfering machining at the same time. The drilling blade completes the drilling machining of a part, the upper chamfering edge and the lower chamfering edge complete the two-sided chamfering machining of the part, the drilling machining process of an original part is improved, four processes are changed into two processes, working efficiency and machining accuracy are improved, and producing cost is greatly saved.
Description
Technical field
The utility model belongs to the Machining Technology field, relates in particular to a kind of drilling part cutter.
Background technology
In the metal cutting field, Drilling operation occupies very large proportion, and boring generally all can be carried out chamfered to the edge in hole after finishing.The thin wall component of the sheet that thin-walled parts is a kind of complex structure, be made of on-plane surface.When it being carried out Drilling operation and the tow sides edge in hole carried out chamfered, the main processing technology that adopts is at present: clamping parts faces up it, boring and processing upper surface chamfering, clamping parts makes its reverse side up again, processing reverse side chamfering.Existing processing technology need to be used two drilling tools, and long processing time, efficient are low; Secondary clamping produces position error; The associated production costs such as cutter use are higher.Existing drilling tool can not be finished boring and Double-side rounding processing simultaneously, has caused existing processing technology can not improve for a long time, has limited the operating efficiency of drilling part.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of thin-walled parts drilling tool, comprise knife bar body and boring sword, characterized by further comprising chamfering blades and lower chamfering blades, upper chamfering blades upper end is connected with described knife bar body, and the lower end is connected with lower chamfering blades upper end, and lower chamfering blades lower end is connected with described boring sword, less than the upper end diameter of upper chamfering blades, the lower end shape of upper chamfering blades is identical with the upper end shape of lower chamfering blades greater than the lower end diameter of upper chamfering blades for the diameter of described boring sword.
Described upper chamfering blades and described lower chamfering blades are integrated.
Described knife bar body, boring sword, upper chamfering blades and lower chamfering blades are integrated.
The sword height of described boring sword is 0.4-0.6mm.
The beneficial effects of the utility model are: chamfering blades and lower chamfering blades on existing drilling tool has added, so that the utility model can be finished drilling part and Double-side rounding processing simultaneously.The boring sword is finished the Drilling operation of part, upper chamfering blades and lower chamfering blades are finished the Double-side rounding processing of part, so that former drilling part processing technology improves, become two procedures by four procedures, improve operating efficiency and machining accuracy, greatly saved production cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Among the figure, 1. knife bar body; 2. boring sword; 3. go up chamfering blades; 4. descend chamfering blades.
As shown in Figure 1, upper chamfering blades 3 upper ends are connected with knife bar body 1, the lower end is connected with lower chamfering blades 4 upper ends, lower chamfering blades 4 lower ends are connected with boring sword 2, boring sword 2 diameter greater than the lower end diameter of upper chamfering blades 3 less than the upper end diameter of upper chamfering blades 3, the lower end shape of upper chamfering blades 3 is identical with the upper end shape of lower chamfering blades 4, and knife bar body 1, boring sword 2, upper chamfering blades 3 and lower chamfering blades 4 are integrated, and the sword height of boring sword 2 is 0.5mm.
During use, first sheet part is fixed, then use the utility model sheet part to be holed from top to bottom, utilize boring sword 2 to finish Drilling operation, translation the utility model then, chamfering blades 3, lower chamfering blades 4 are contacted with sheet part, and the utility model is carried out circular motion, and upper chamfering blades 3, lower chamfering blades 4 are finished respectively the chamfer machining to the up and down two edges in sheet part hole.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
