Description

Detachable shaping cutterhead

Technical field

The utility model belongs to mobile phone shell processing technique field, more particularly to the removable cutterhead of cambered surface mobile phone shell processing.

Background technology

Mobile phone shell is the indispensable functional part and appearance member of mobile phone, mobile phone shell, especially mobile phone shell periphery position, base This is all designed with cambered surface, especially 2D, 3D mobile phone shell, and the design of its cambered surface is essential, and quantity is many, the hand of prior art Casing curved face processing, using cutter is integrally formed, the whole branch cutter changing just needed together with axis handle of a knife has been worn in production, Machine-shaping cutter expense spy is expensive, causes cambered surface mobile phone shell processing efficiency low, and cost is high.

Utility model content

Based on this, for prior art, technical problem to be solved of the present utility model is just to provide a kind of structure letter List, high efficiency, the detachable shaping cutterhead of low cost.

The technical solution of the utility model is：

A kind of detachable shaping cutterhead, including axis handle of a knife, split clip cutterhead and the knife grain that can change jobs, the axis Handle of a knife is inlaid on the rotation central axis of the removable shaping cutterhead, and the split clip cutterhead is three layers of clip matable assembly, The knife grain that changes jobs, which is detachably set with, to be fixed in the split clip cutterhead, it is described change jobs knife grain for quantity at least For 6 on the centrosymmetric even number working tool of the axis handle of a knife, by the axis handle of a knife middle shaft rotation, described point The knife grain rotation that can be changed jobs described in the drive of body clip cutterhead carries out the curved face processing of workpiece to be processed.

In one of the embodiments, the split clip cutterhead includes bearing chassis, fixed fixture block, fixture block fixation spiral shell Silk, the solid snap ring in top and snap ring fixed screw, the bearing chassis are the disk provided with rotation central axis hole, and the fixed fixture block is circle Ring matrix distribution can change jobs the holding part of knife grain described in the bearing chassis, be formed between every 2 fixed fixture block Can change jobs the neck of knife grain described in clip, and the fixed fixture block is fixed on the bearing chassis by the fixture block fixed screw On, the solid snap ring card in top is pressed in the upper surface of the knife grain that can change jobs, and the solid snap ring in top fixes spiral shell by the snap ring Silk is fixedly connected with the axis handle of a knife.

In one of the embodiments, the knife grain number amount that changes jobs is 10.

In one of the embodiments, the radial dimension of operative end surface of knife grain of can changing jobs is more than the split clip knife Disk.

Compared with the prior art, detachable shaping cutterhead of the present utility model, by can tool changing grain, general axis handle of a knife With the sustainable use of split clip cutterhead, the cost of material is low, a cutterhead can fill 10 can tool changing grain, can effectively reduce and use knife instead Has frequency, there is provided unit production capacity, interchangeable cutter head structure is simple, and integrated cost is lower.

Brief description of the drawings

Fig. 1 is detachable shaping cutter head structure schematic diagram of the present utility model.

In figure, 10-- axis handle of a knifes；20-- split clip cutterheads；21-- bearing chassis；22-- fixes fixture block；23-- fixture blocks Fixed screw；The solid snap ring in 24-- tops；25-- snap ring fixed screws；30-- can change jobs knife grain.

Embodiment

Below with reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.It should be noted that do not rushing In the case of prominent, the feature in following embodiment and embodiment can be mutually combined.

Fig. 1 gives the structural representation of detachable shaping cutterhead of the present utility model, and as seen from the figure, this is detachable Cutterhead is molded, including axis handle of a knife 10, split clip cutterhead 20 and the knife grain 30 that can change jobs, axis handle of a knife 10 are inlaid in removable It is molded on the rotation central axis of cutterhead 20, split clip cutterhead 20 is three layers of clip matable assembly, can change jobs knife grain 30 detachably Suit be fixed in split clip cutterhead 20, the knife grain 30 that can change jobs be quantity be at least 6 on the center pair of axis handle of a knife 10 The even number working tool of title, by the middle shaft rotation of axis handle of a knife 10, split clip cutterhead 20 drives the knife grain 30 that can change jobs to revolve Rotate into the curved face processing of row workpiece to be processed.

Split clip cutterhead 20 includes bearing chassis 21, fixed fixture block 22, fixture block fixed screw 23, the solid snap ring 24 in top and card Ring fixed screw 25, bearing chassis 21 are the disk provided with rotation central axis hole, and fixed fixture block 22 is that annulus matrix distribution is carrying The holding part of the knife grain 30 that changes jobs on chassis 21, clip is formed between every 2 fixation fixture block 22 can change jobs the card of knife grain 30 Groove, fixed fixture block 22 are fixed in bearing chassis 21 by fixture block fixed screw 23, are pushed up the solid card of snap ring 24 and are pressed in the knife that can change jobs The upper surface of grain 30, push up solid snap ring 24 and be fixedly connected by snap ring fixed screw 25 with axis handle of a knife 10.

The quantity of knife grain 30 that can change jobs is 10.The radial dimension of operative end surface of knife grain 30 of can changing jobs is more than split clip Cutterhead 20.

From the above, it may be appreciated that detachable shaping cutterhead of the present utility model, by can tool changing grain, general axis handle of a knife and The sustainable use of split clip cutterhead, the cost of material is low, a cutterhead can fill 10 can tool changing grain, can effectively reduce and use cutter instead Frequency, there is provided unit production capacity, interchangeable cutter head structure is simple, and integrated cost is lower.

Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed, But therefore it can not be interpreted as the limitation to the utility model patent scope.It should be pointed out that for the common of this area For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
