Abstract
The utility model discloses a rose reamer, which comprises a reamer bar and a reamer head, wherein the reamer head is provided with a first cutting edge, a second cutting edge and a third cutting edge, a transitional surface with a shrunk diameter, which forms a 30-degree taper angle with the reamer bar in the axial direction, is arranged between the reamer bar and the reamer head, the first cutting edge is connected with the lower end of the transitional surface, the first cutting edge is axially parallel with the reamer bar, the second cutting edge is connected with the lower end of the first cutting edge, the axial included angle of the second cutting edge and the reamer bar is 6.71 degrees, and the third cutting edge is arranged on the lower end surface of the reamer head. The machining surface of the rose reamer disclosed by the utility model has good smoothness, and the processing efficiency is high.
Description
Technical field
The utility model relates to the cutter field, particularly a kind of rose reamer that is used for the PC plastic parts is carried out chamfer machining.
Background technology
When the PC plastic parts is carried out chamfering, normally carry out chamfering with common drill bit or lathe tool, add man-hour for some workpiece with groove; Need process a groove earlier, and then do chamfering, can't once accomplish the processing and the chamfering of groove; Working (machining) efficiency is low; And because be to process in two steps, so the fineness of finished surface often can't reach requirement, machined surface quality is relatively poor.
Summary of the invention
When the purpose of the utility model was to the existing chamfer tool processing PC plastic parts described in the background technology, processed surface smoothness can't reach requirement, and the machined surface quality difference gets problem, and a kind of rose reamer that can solve foregoing problems is provided.
The technical scheme of goal of the invention that can realize the utility model is following:
A kind of rose reamer comprises knife bar and cutter head, and described cutter head is provided with first cutting edge, second cutting edge and the 3rd cutting edge; Be provided with and the excessive face of cutter spindle between knife bar and the cutter head to the reduced that becomes 30 ° of cone angles; First cutting edge is connected with the lower end of excessive face, first cutting edge and knife bar axially parallel, and second cutting edge is connected with the lower end of first cutting edge; Second cutting edge and cutter spindle to angle be 6.71 °, the 3rd cutting edge is arranged on the lower surface of cutter head.
The vertical height of described second cutting edge is 1.19mm～1.21mm.
The length of described the 3rd cutting edge is 1.71mm～1.73mm.
The beneficial effect of the utility model has three sections cutting edges for the rose reamer because of the utility model; The 3rd cutting edge major function on the cutter head lower surface is a fluting, and the function of first cutting edge and second cutting edge is a chamfering, through the cooperation of three sections cutting edges; Can disposable completion fluting and the operation of chamfering; Improved operating efficiency,, improved the surface quality of workpiece because processing continuity so processed surface smoothness are good.
Description of drawings
Fig. 1 is the sketch map of the utility model;
Among the figure, 1 is knife bar, and 2 is cutter head, and 3 is first cutting edge, and 4 is second cutting edge, and 5 is the 3rd cutting edge, and 6 is excessive face.
The specific embodiment
With reference to a kind of rose reamer shown in Figure 1; It is characterized in that: comprise knife bar 1 and cutter head 2; Described cutter head 2 is provided with first cutting edge, second cutting edge 4 and the 3rd cutting edge 5, is provided with between knife bar 1 and the cutter head 2 with knife bar 1 axially to become excessive face 6, the first cutting edges of the reduced of 30 ° of cone angle a to be connected with the lower end of excessive face 6; First cutting edge and knife bar 1 axially parallel; Second cutting edge 4 is connected with the lower end of first cutting edge, and second cutting edge 4 is 6.71 ° with knife bar 1 axial angle b, and the 3rd cutting edge 5 is arranged on the lower surface of cutter head 2; The vertical height of described second cutting edge 4 is 1.19mm～1.21mm; The length of described the 3rd cutting edge 5 is 1.71mm～1.73mm.
Claims (3)
