Abstract
The utility model relates to a hollow milling cutter. The hollow milling cutter is characterized by comprising a cutter handle and a milling cutter head integrated with the cutter handle, wherein the milling cutter head is a rotary body, the central part of the milling cutter head is provided with a hollow part, and cutting blades of the milling cutter head comprises an internal cutting blade and an external cutting blade; and the internal cutting blade is formed by an arc blade and a chamfering blade which are sequentially welded end to end, the external cutting blade is formed by sequentially welding a first chamfering blade and a second chamfering blade end to end, and an included angle between the inclined plane of the first chamfering blade and the centre line of the cutter handle is equal to an included angle between the inclined pane of the second chamfering blade and the centre line of the cutter handle. The milling cutter is mainly used for one-time inner and outer machining of a plurality of holes in shells of electronic products, and is applied in the mass product machining. According to the hollow milling cutter, the peripheries of the holes are machined by the internal cutting blade, and the inner sides of the holes are machined by the external cutting blade, so that the one-time mass machining is realized, and the work efficiency is greatly improved.
Description
Technical field:
The utility model relates to the cutter in a kind of machining, relates in particular to a kind of hollow milling cutter.
Background technology:
Milling cutter is for Milling Process, have the rotary cutter of one or more cutters tooth.During work, each cutter tooth cuts the surplus of workpiece successively off and on.Milling cutter is mainly used in processing plane, hole milling, step, groove, profiled surface and cut-out workpiece etc. on milling machine.
At present, requirement on machining accuracy to the hole in being applied to machining is higher, when carrying out the post-production processing in a plurality of holes on to a product, if carry out chamfering, processing step hole and other processing steps on the hole according to it, need to change different milling cutters and process processing, like this, the cost that has not only strengthened milling cutter drops into, and working (machining) efficiency is also very low simultaneously.
Summary of the invention:
The technical problem that the utility model solves is to provide a kind ofly increases work efficiency for the disposable processing technology of completing, the hollow milling cutter of particularly applicable disposable processing in enormous quantities.
The technical scheme in the invention for solving the technical problem is: a kind of hollow milling cutter, comprise handle of a knife and with the milling head of handle of a knife one, described milling head is the single-revolution body, central part at described milling head offers hollow bulb, and the cutting edge of milling head is divided into interior cutting edge and outer cutting edge.
Further, for the profile in hole being carried out disposable circular arc and the chamfered completed, described interior cutting edge is welded to form end to end by Roound edge and chamfering blades order.
Further, for the inwall to the hole carries out stepped hole processing, and complete simultaneously step place chamfered, and described outer cutting edge is welded to form end to end by the first chamfering blades and the second chamfering blades order, and oblique the angle with the handle of a knife center line of described the first chamfering blades and the second chamfering blades equates.
Further, in order to prevent the milling head withdrawing time and workpiece bump, offer escape in the junction of described handle of a knife and milling head, the width of this escape is less than 1mm.
The beneficial effect of this device: this cutter is mainly used in the inside and outside disposable processing in a plurality of holes on electronic product casing, it is applied in the processing of mass product, in utilizing, cutting edge is processed the periphery in hole, utilize outer cutting edge that the inboard in hole is processed, realize the processing processing of disposable volume, greatly improved operating efficiency.
Description of drawings:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of reamer head in the utility model.
In figure: 1, handle of a knife 2, milling head 21, interior cutting edge 211, Roound edge 212, chamfering blades 22, outer cutting edge 221, the first chamfering blades 222, the second chamfering blades 3, escape.
The specific embodiment:
A kind of hollow milling cutter as shown in Figure 1, comprise handle of a knife 1 and with the milling head 2 of handle of a knife one, described milling head 2 is the single-revolution body, offers hollow bulb at the central part of described milling head 2, and the cutting edge of milling head 2 is divided into interior cutting edge 21 and outer cutting edge 22.
Further, as shown in Figure 2, for the profile in hole being carried out disposable circular arc and the chamfered completed, described interior cutting edge 21 is welded to form end to end by Roound edge 211 and chamfering blades 212 orders.
Further, as shown in Figure 2, for the inwall to the hole carries out stepped hole processing, and complete simultaneously step place chamfered, described outer cutting edge 22 is welded to form end to end by the first chamfering blades 221 and the second chamfering blades 222 orders, and oblique the angle with the handle of a knife center line of described the first chamfering blades 221 and the second chamfering blades 222 equates.
Further, in order to prevent the milling head withdrawing time and workpiece bump, offer escape 3 in the junction of described handle of a knife 1 and milling head 2, the width of this escape 3 is less than 1mm.
This cutter is mainly used in the inside and outside disposable processing in a plurality of holes on electronic product casing, it is applied in the processing of mass product, in utilizing, the periphery in 21 pairs of holes of cutting edge is processed, utilize the inboard in outer cutting edge 22 pairs of holes to process, demand according to actual apertures profile and inwall processing dimension and shape, its described interior cutting edge 21 and outer cutting edge 22 can carry out specific offering according to actual needs, realize that the processing of disposable volume is processed, and have greatly improved operating efficiency.
It is emphasized that, it is more than better implementation column of the present utility model, be not that the utility model is done any type of restriction in appearance, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
