Abstract
The utility model belongs to the tool field, and in particular relates to a circular arc T-cutter. The circular arc T-cutter comprises a holder connected with a drill, wherein the front end of the holder is connected with a connecting rod, and the connecting rod is connected with a cutting part. The cutter is characterized in that the end part of the cutting part is provided with a horizontal cutting blade, the side of the cutting part is provided with a side cutting blade, and an arc cutting blade is arranged between the horizontal cutting blade and the side cutting blade. The T-cutter provided by the utility model overcomes the limitation in the traditional tooling, solves the problem that an inner wall notch of a small shell cannot be processed in production, meanwhile, improves the processing precision and processing efficiency and meets the production requirement.
Description
Technical field
The utility model belongs to the cutter field, particularly the T-shaped cutter of a kind of circular arc.
Background technology
On the housing of more existing electronic equipments, need to process at the inwall of housing the notch of caulking groove and so on, when if the volume of housing is larger, can come notch is processed by the locate mode of changing housing, but the housing to some small volumes, adjust the locate mode of housing and still can't process the notch of inner walls, can't meet the needs of production.
Summary of the invention
The utility model is for the deficiencies in the prior art, designed a kind of T-shaped cutter of circular arc for the processing arc-shaped slot, and the shape that it can time processing goes out notch need not to repeat to change locate mode, has guaranteed the precision of processing and the efficient of processing.
The utility model is achieved through the following technical solutions:
The T-shaped cutter of circular arc, it comprises the handle of a knife that is connected with drilling machine, the front end of described handle of a knife is connected with connecting rod, be connected with cutting portion on the described connecting rod, it is characterized in that: the end of described cutting portion is provided with the horizontal cutting sword, the side of cutting portion is provided with the side cutting edge, is provided with the arc milling sword between described horizontal cutting sword and the side cutting edge.
Described handle of a knife and connecting rod junction are provided with conus portion, the angle of the described conical surface is 60 °, the conus portion that arranges can be stepped down to the edge of housing, and preventing that cutter from touching does not need the housing processed, has guaranteed that housing is through the surface quality after the processing.
In sum, the utlity model has following advantage: the utility model has overcome the limitation of conventional tool processing, solve the problem that medium and small inner walls notch can't be processed of producing, also improved machining accuracy and working (machining) efficiency simultaneously, satisfied the needs of producing.
Description of drawings
Fig. 1 is structural representation of the present utility model;
1 is handle of a knife among the figure, and 2 is conus portion, and 3 is connecting rod, and 4 is the side cutting edge, and 5 is the horizontal cutting sword, and 6 is the arc milling sword.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The T-shaped cutter of circular arc as shown in Figure 1, it comprises the handle of a knife 1 that is connected with drilling machine, the front end of described handle of a knife 1 is connected with connecting rod 3, be connected with cutting portion on the described connecting rod 3, it is characterized in that: the end of described cutting portion is provided with horizontal cutting sword 5, the side of cutting portion is provided with side cutting edge 4, is provided with arc milling sword 6 between described horizontal cutting sword 5 and the side cutting edge 4.
Described handle of a knife 1 is provided with conus portion 2 with connecting rod 3 junctions, the angle of the described conical surface is 60 °, the conus portion that arranges can be stepped down to the edge of housing, and preventing that cutter from touching does not need the housing processed, has guaranteed that housing is through the surface quality after the processing.
In sum, the utlity model has following advantage: the utility model has overcome the limitation of conventional tool processing, solve the problem that medium and small inner walls notch can't be processed of producing, also improved machining accuracy and working (machining) efficiency simultaneously, satisfied the needs of producing.
