Description
Technical field
The utility model relates to a kind of cutter, specifically is a kind of declivous cutting edge circular arc type chisel.
Background technology
Traditional chisel, its cutter hub and handle are fixing non-removable, and the anterior blade of cutter hub is the straight knife body, and the cutting edge of blade front end is a flat edge.There is following defective in this chisel: at first, because cutter hub and handle are on-dismountable, and handle often damages easily, in case handle damages, whole chisel just is difficult to use even scrap; Secondly, straight knife body, flat edge are inconvenient to inner peripheral surface feed, the processing of tubular article, especially are difficult to protruding from the projection chamfering on the inner peripheral surface.
Summary of the invention
The technical problem that the utility model will solve is to provide a kind of cutter hub and handle the detachable and convenient declivous cutting edge circular arc type chisel of processing the inner peripheral surface of tubular article.
The technical solution of the utility model is, a kind of declivous cutting edge circular arc type chisel is provided, and it comprises cutter hub and handle; Cutter hub comprises anterior blade and back bar, and handle is through with centre bore, and handle rear end is provided with the termination; The rear end that back bar passes handle center hole and back bar is connected with the termination is removable; Be provided with latch between handle and the back bar, blade is the circular arc type blade, and the cutting edge of blade front end is a declivous cutting edge.
The declivous cutting edge circular arc type chisel of the utility model compared with prior art has the following advantages:
Because the back bar is connected with the termination is removable; Like this, extract the latch between handle and the back bar, then back bar and termination are taken apart; Just can make things convenient for smoothly cutter hub is separated with handle; So after if handle damages, can change timely and conveniently, be difficult to after having avoided handle to damage to use even situation that whole chisel is scrapped; Again because blade is the circular arc type blade; The circular arc type blade is very convenient to inner peripheral surface feed, the processing of tubular article, and, because circular arc type blade front end is a declivous cutting edge; So the inner peripheral surface of convenient processing tubular article is particularly useful for the projection on the protrusion inner peripheral surface is carried out chamfering.
As improvement, the termination is made up of end cap and internal thread sleeve pipe, and the internal thread sleeve pipe is contained in the centre bore; The external diameter of end cap is greater than the aperture of centre bore, and back bar is provided with external screw thread, and back bar and internal thread sleeve pipe screw; Like this; The end cap of termination is stuck in outside the centre bore of handle, and the back bar and the termination of cutter hub screw, and it is all convenient to make cutter hub be connected, dismantle with handle.
As improving again; Handle is provided with radial direction through hole; The position corresponding with radial direction through hole is provided with radially pin-and-hole on the back bar of cutter hub, and latch passes radial direction through hole and inserts radially in the pin-and-hole, like this; Can be quickly and easily that cutter hub and handle is circumferentially spacing through latch, prevent that the cutter hub rotation from getting loose from the internal thread sleeve pipe of termination.

Fig. 2 is the side sectional structure sketch map of the utility model declivous cutting edge circular arc type chisel.
Fig. 3 is the structural representation of the utility model declivous cutting edge circular arc type chisel to the projection chamfering on the protrusion inner peripheral surface.
Shown in the figure 1, cutter hub, 1.1, blade, 1.2, the back bar, 1.3, cutting edge, 2, handle, 2.1, centre bore, 3, the termination, 3.1, end cap, 3.2, the internal thread sleeve pipe, 4, latch, 5, the projection on the protrusion inner peripheral surface.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Like Fig. 1, Fig. 2, shown in Figure 3, the utility model declivous cutting edge circular arc type chisel, it comprises cutter hub 1 and handle 2.Cutter hub 1 comprises anterior blade 1.1 and back bar 1.2.Handle 2 is through with centre bore 2.1, and handle 2 rear ends are provided with termination 3.Back bar 1.2 passes the rear end and 3 removable connections of termination of handle 2 centre bores 2.1 and back bar 1.2; Be that termination 3 is made up of end cap 3.1 and internal thread sleeve pipe 3.2; Internal thread sleeve pipe 3.2 is contained in the centre bore 2.1; The external diameter of end cap 3.1 is greater than the aperture of centre bore 2.1, and back bar 1.2 is provided with external screw thread, and back bar 1.2 screws with internal thread sleeve pipe 3.2.In particular, the centre bore 2.1 of handle 2 is divided into preceding hole and metapore, and the metapore aperture is greater than aperture, preceding hole, and internal thread sleeve pipe 3.2 is contained in the metapore, and the external diameter of end cap 3.1 is greater than the aperture of the metapore of centre bore 2.1.Handle 2 and back are provided with latch 4 between the bar 1.2, and promptly handle 2 is provided with radial direction through hole, and the position corresponding with radial direction through hole is provided with radially pin-and-hole on the back bar 1.2 of cutter hub 1, and latch 4 passes radial direction through hole and inserts radially in the pin-and-hole.Blade 1.1 is a circular arc type blade 1.1, and the cutting edge 1.3 of blade 1.1 front ends is a declivous cutting edge 1.3.Because circular arc type blade 1.1 front ends are declivous cutting edge 1.3, so be particularly useful for the projection 5 on the protrusion inner peripheral surface is carried out chamfering.
