Embodiment: a kind of cambered surface cutting tool, as shown in Figure 1, including 1 He of rotation axis for being fixedly connected on motor output shaft
It is fixedly connected on the circular beater plate 2 of rotation axis 1, cutterhead 2 is uniformly provided with several first grooves 21, the first groove 21 along its circumferential direction
Run through cutterhead 2 along 2 axis direction of cutterhead, one of inner wall of the first groove 21 is connected with for cutting workpiece for cambered surface
Blade 3, blade 3 is in a circular table shape, and the bottom surface of blade 3 is connect with 21 inner wall of the first groove.In use, motor driven rotation axis
1 rotation, and then move in a circle with movable knife disc 2, by the curved face contact of workpiece and blade 3, blade 3 does circumference fortune with cutterhead 2
In dynamic process, the curved surface of blade 3 cuts workpiece for cambered surface.Realize the purpose that cambered surface cutting operation is carried out to workpiece.
When causing abrasion to blade 3 using the workpiece hardness either having over time is larger, grind in order to prevent
Damage blade 3 affects to the cutting of next workpiece.It, can by hex bolts 4 between blade 3 and cutterhead 2 in conjunction with Fig. 2
The central axis of dismantling connection, hex bolts 4 is overlapped with the central axis of blade 3.When thering is workpiece to abut with blade 3,
The power that blade 3 is received is uniformly, to prevent blade 3 from damaging because of discontinuity.When blade 3 is worn, by abrasion
Blade 3 and cutterhead 2 are dismantled, and the cutting that a new blade 3 continues subsequent workpiece is then changed.
The second groove 22 is offered on another inner wall of first groove 21, the second groove 22 is in the opposite of blade 3.
The slot bottom of second groove 22 is in arc-shaped, and the distance between slot bottom and 3 center of blade gradually increase along the direction far from blade 3
Greatly.When needing to back-out hex bolts 4, hex bolts 4 is in the first groove 21 and the second groove 22 with cutting blade 3
It is interior, so that hex bolts 4 has enough spaces when back-out.Second groove 22 is set as arc-shaped and screwing out hexagonal spiral shell
Bolt 4 with cutting blade 3 far from cutterhead 2 during, the curved surface of cutterhead 2 is along the slot bottom of the second groove 22 away from cutterhead 2
Direction movement.The disassembly process for neither influencing blade 3 is arranged such, while can also farthest keep the intensity of cutterhead 2.
As shown in Fig. 2, blade 3 constantly contacts grinding, knife with workpiece far from 1 side of rotation axis in 2 rotation process of cutterhead
During piece 3 and grinding workpieces, blade 3 is because only that side stress causes the bending of blade 3 impaired.Such case in order to prevent
Occur, offers third groove 23, cell wall of the third groove 23 far from 3 one end of blade and blade 3 in the slot bottom of the first groove 21
It is equipped with supporting block 5 between 1 side of rotation axis, is detachably connected between supporting block 5 and cutterhead 2 by hex bolts 4, hexagonal
The length of bolt 4 is arranged radially along cutterhead 2.
As shown in Fig. 2, when supporting block 5 is along the rectangular triangle of sectional area of 1 radial direction of rotation axis, it can also be rectangular
Trapezoidal (in conjunction with Fig. 3).When sectional area rectangular triangle of the supporting block 5 along 1 radial direction of rotation axis, supporting block 5 is wherein
One right-angle surface and the cell wall of third groove 23 fit closely, another right-angle surface is supported far from 22 side of the second groove with blade 3
Tightly.
As shown in figure 3, when supporting block 5 is in a rectangular trapezoid along the sectional area of 1 radial direction of rotation axis, supporting block 5 it is upper
Bottom surface and bottom surface are abutted with the inner wall of blade 3 and third groove 23 respectively.The supporting block 5 of above two shape all makes blade
Have bigger space between 3 and third groove 23, convenient for users to by hand be placed in third groove 23 to blade 3 carry out operation or
It checks, and does not influence the fixation of blade 3 Yu cutterhead 2.But work as supporting block 5 along the sectional area of 1 radial direction of rotation axis in straight
When angle is trapezoidal, supporting block 5 and the contact area of blade 3 are larger, supporting block 5 are supported blade 3 more stable, into
One step reduces blade 3 because only that the probability that side stress causes the bending of blade 3 impaired.
The course of work: when needing to carry out cambered surface cutting to workpiece, motor driven rotation axis 1 is rotated, and then does with movable knife disc 2
Circular motion, by the curved face contact of workpiece and blade 3, during blade 3 moves in a circle with cutterhead 2, the curved surface of blade 3
Workpiece is cut as cambered surface.It, first will be between supporting block 5 and cutterhead 2 when using, needing to replace blade 3 over time
Hex bolts 4 along far from rotation axis 1 direction screw out, supporting block 5 and cutterhead 2 are detached from, then by blade 3 and cutterhead 2
Between hex bolts 4 screwed out along close to the direction of third groove 23, band cutting blade 3 is far from cutterhead 2, until hex bolts 4
It falls off with cutterhead 2, then changes a new blade 3.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
