Abstract
The utility model discloses a milling machine cutting tool with an overload protection function. The milling machine cutting tool with the overload protection function comprises a shank and a tool bit, wherein the tool bit is inserted into the shank; a tapered inner hole is formed in the shank; the tool bit comprises a connecting part and a cutting edge part; the outer surface of the connecting part is the same as that of the inner hole; a positioning fin is arranged on the outer wall of the connecting part; a positioning groove used with the positioning fin in a matching manner is formed in the hole wall of the inner hole; a connecting piece is arranged at the end, far away from the tool bit, of the shank; an external thread is formed in the connecting piece; the connecting piece is matched with a sealing cover through the external thread; an arc groove is formed in the cutting edge part of the tool bit. According to the milling machine cutting tool, the groove is formed in the cutting edge part, so that the tool bit is broken at the groove when being subjected to great impact, the cutting tool is prevented from being wholly damaged when being impacted, and the using and maintenance costs of the cutting tool are reduced.
Description
Technical field
The utility model relates to a kind of cutter for milling machines with overload protection function.
Background technology
Milling machine is carrying out in workpiece working angles, due to the setting problem of the amount of feeding and cutter benefit, can cause cutter penetraction depth excessively dark, or cutter admission velocity is too fast, can make cutter be subject to scrapping compared with large impact, and existing milling cutter is mostly integral type, after being clashed into, can only scrap, then integral replacing, has increased use cost.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of cutter for milling machines with overload protection function; the knife edge part of this device has a groove; therefore in the time being subject to greater impact; cutter head is in this groove position fracture; while avoiding being subject to clashing into, damage whole cutter, reduced the operation and maintenance cost of cutter.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of cutter for milling machines with overload protection function, comprise handle of a knife and cutter head, described cutter head assigns in described handle of a knife, described handle of a knife has the endoporus of a taper, described cutter head comprises coupling part and knife edge part, described coupling part has the outer surface identical with described endoporus, on the outer wall of described coupling part, be provided with location fin, on the hole wall of described endoporus, be provided with the locating slot being used in conjunction with this location fin, described handle of a knife has a connecting portion away from one end of cutter head, connecting portion has external screw thread, and be combined with capping by external screw thread, in described capping, there is a jacking block, described capping is by after screw thread rotation, its jacking block and cutter head end face offset, the knife edge part of described cutter head is provided with the groove of an arc.
As preferred technical scheme, the maximum gauge of described knife edge part is less than the minimum diameter of coupling part.
As preferred technical scheme, on the outer wall of described capping, be provided with knurled portions.
As preferred technical scheme, described handle of a knife has the outer surface of a taper, and it is the end that sectional area is less near that one end of cutter head.
The beneficial effects of the utility model are: the knife edge part of this device has a groove, therefore in the time being subject to greater impact, cutter head is in this groove position fracture, while avoiding being subject to clashing into, damage whole cutter, reduced the operation and maintenance cost of cutter, this device has adopted handle of a knife and two parts of cutter head simultaneously, therefore after damaging, only need to replace broken parts, simultaneously this device is installed more for convenience, and structure is also comparatively simple, is therefore adapted at promoting the use of in the daily operation of milling machine.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
