Description
Technical Field
The utility model relates to a mill flat special gang tool.
Background
At present, the pier head part of the high-strength fastener is milled flatly by adopting an end milling cutter. The disadvantages of this processing method are: (1) the utilization rate of the edge of the end mill is low; (2) the processing efficiency is low; (3) the cutter is seriously worn, the cutter is frequently replaced, and the auxiliary time is long.
In view of this, it is necessary to provide a tool with high machining efficiency, long service life and simple replacement operation, and a combined tool is used to replace an end mill for machining.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a mill flat special gang tool is provided, its machining efficiency is high, long service life, changes easy operation.
The utility model adopts the technical proposal that: a special combined cutter for milling flat comprises a cutter bar, a cutter handle arranged at one end of the cutter bar, two milling cutters arranged on the cutter bar and a positioning sleeve arranged between the two milling cutters, wherein a nut used for axially positioning the milling cutters and the positioning sleeve is arranged on the cutter bar.
Furthermore, the positioning sleeve and the two milling cutters are connected with the cutter bar through connecting keys and positioned.
Furthermore, a connecting hole matched with the cutter bar is formed in the milling cutter, and a key groove matched with the connecting key is formed in the connecting hole.
Further, the milling cutter adopts a three-edge milling cutter.
Further, the knife handle is a universal DIN69871 knife handle.
The utility model discloses an actively the effect does: the utility model discloses processing is simple, and through the position sleeve of changing different length, can carry out not unidimensional high strength fastener pier nose position and mill flat, realizes milling cutter, position sleeve and cutter arbor radial and axial positioning through key-type connection and nut, has realized simple structure, changes characteristics such as blade convenient operation and machining efficiency height.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in the attached figure 1, the utility model discloses a general DIN69871 handle of a knife 1 and cutter arbor 2, two milling cutter 3 have been put to the cover on cutter arbor 2, are equipped with position sleeve 4 between two milling cutter 3. Corresponding key grooves are formed among the cutter bar 2, the milling cutter 3 and the positioning sleeve 4 are installed on the cutter bar 2 through a connecting key 5, and radial positioning is achieved.
The cutter handle 1 is fixedly connected with the cutter rod 2, the outer side surface of one milling cutter 3 is matched with a shaft shoulder on the cutter rod 2, the outer side wall of the other milling cutter 3 is in contact fit with a nut 6 matched on the cutter rod 2, and the axial positioning of the milling cutter 3 and the positioning sleeve 4 is realized. The milling cutter 3 and the positioning sleeve 4 can be detached by removing the nut 6, and flat milling with different lengths can be adapted by replacing the positioning sleeve 4 with different lengths.
The milling cutter 3 adopts a replaceable blade three-face edge milling cutter, a connecting hole matched with the cutter bar 2 is formed in the milling cutter, and a key groove in the milling cutter is formed in the inner side of the connecting hole.
The utility model discloses a gang tool simple structure, convenient operation, machining efficiency are high, long service life, and the commonality is strong, accords with the quick change requirement.
The utility model discloses an installation method as follows:
general DIN69871 handle 1 is connected fixedly with cutter arbor 2, realizes milling cutter 3, position sleeve 4 and the radial positioning of cutter arbor 2 through connecting key 5, realizes milling cutter 3, position sleeve 4 and the axial positioning of cutter arbor 2 through nut 6, changes the position sleeve 4 of different length to the flat milling of different length of adaptation.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the present invention.
