Abstract
The utility model relates to a mechanical cutter and particularly to a cutter for machining the end surface and the fillet at the root of a stepped hole. The cutter is composed of a cutter bar and a cutter bit and characterized in that the tail end of the cutter bar is vertically connected with a rod-shaped cutterhead, the end of the rod-shaped cutterhead is vertically provided with an open key slot, the opening of the open key slot faces to the starting end of the cutter bar, and the cutter bit is arranged in the key slot and fastened by using a fastening bolt I, so that the cutter bar can conveniently enter from the small end of a workpiece, and then, the cutterhead with the cutter bit is arranged from the large end of the workpiece. The cutter is convenient to operate, simple in structure and high in machining precision.
Description
Technical field
The utility model relates to a kind of machinery knives, is specifically related to a kind of for the end face of processing step hole root and the cutter of fillet.
Background technology
When the processing step hole root, when large bore dia during less than or equal to 2 times hole diameter, can process from small bore end the fillet of macropore root.When large bore dia during greater than 2 times hole diameter, cutter can't enter from small end, at this moment common way is from large end processing, add man-hour from large end, because large stomidium length is longer, knife bar is in vacant state, add man-hour, the knife bar vibrations are serious, affect processing dimension and surface roughness, will affect the use of workpiece when serious.Given this, we have invented the cutter of processing step heel fillet and end face.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art and provides a kind of simple in structure, the cutter of the processing step hole root that machining accuracy is high.
The purpose of this utility model is achieved in that a kind of cutter for the processing step hole root, comprise knife bar, cutter head, it is characterized in that: described knife bar end vertically is connected with a shaft-like cutterhead, the end of shaft-like cutterhead is vertically installed with an opening keyway, the opening of described opening keyway is towards the initiating terminal of knife bar, described cutter head is installed in the keyway, and fastening by fastening bolt one.
Fastening by fastening bolt two between described knife bar and the shaft-like cutterhead.
Described knife bar is connected with the centre of shaft-like cutterhead.
The utlity model has following advantage: can very easily the small end of knife bar from workpiece be entered, then will load onto with the cutterhead of cutter head from the large end of workpiece, easy to operate, simple in structure, the precision of processing is high.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of duty of the present utility model.
Fig. 3 is the structural representation with the cutterhead of opening keyway.
The specific embodiment
The utility model will be further described below in conjunction with specific embodiment.
As shown in Figure 1, 2, a kind of cutter for the processing step hole root, comprise knife bar 1, cutter head 2, described knife bar 1 end vertically is connected with a shaft-like cutterhead 3, the end of shaft-like cutterhead 3 is vertically installed with an opening keyway 3-1, the opening of described opening keyway 3-1 is towards the initiating terminal of knife bar 1, and described cutter head 2 is installed in the keyway 3-1, and fastening by fastening bolt 1.
Fastening by fastening bolt 25 between described knife bar 1 and the shaft-like cutterhead 3.
Described knife bar 1 is connected with the centre of shaft-like cutterhead 3.
To process a keyway 3-1 on the cutterhead, cutter head 2 keyway of packing into, fixing by fastening bolt 1, move up and down by cutter head, can adjust the tool sharpening scope.Add man-hour, workpiece is fixed on the boring machine workbench, knife bar is packed into from the workpiece small end, cutter head is fixed on the cutterhead, and integral body is contained on the knife bar from the large end of workpiece, by moving up and down of boring spindle, drive knife bar, thereby move up and down end face and the fillet of processing macropore root with movable knife disc.
