Specific embodiment
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control attached drawing is described in detail
The specific embodiment of the present invention.
A kind of Automatic-clamping cutter claw as shown in Figs. 1-2, Automatic-clamping cutter claw include installing plate 3, the first cutter claw 1 and the
The handle of a knife 4 of both two cutter claws 2, the first cutter claw 1, the second cutter claw 2 is rotatably arranged on installing plate 3, and the handle of a knife 4 of the two is clamped with one
Block 6, the block 6 are fixed on installing plate 3, the first cutter claw 1, the second cutter claw 2 point of a knife 5 between be formed with grasping part
50, the front end 51 of point of a knife 5 is preferably bent inwardly, is formed with blocking, effectively cutter is avoided to be thrown out of.First cutter claw 1, the second cutter claw
2 rotate the folding to adjust grasping part 50 along handle of a knife 4, and the bullet for generating chucking power is equipped between the two handle of a knife 4
Property part.In exchanging knives process, elastic component causes cutter claw to have lasting, enough clamping forces, and handle of a knife 4 is got rid of when preventing the tool magazine from rotating
Go out, while ensure air-floating main shaft radially when grabbing knife, the flexible adjustment that can take advantage of a situation of grasping part 50 forms buffering so that air-floating main shaft
The radial load of suitable size is born, prevents from being damaged.Block 6 is generally located between two handle of a knifes 4 close to the position of point of a knife 5, and
The setting of block 6 can limit main shaft the first cutter claw 1, opening degree range of the second cutter claw 2 when putting knife and taking knife, make two knives
The folding of pawl equity relatively forms the chucking power of equalization stable.
For the ease of installing elastic component, also simplify technique, cost-effective, sets of holes are opened up on two handle of a knifes 4, by elastic component
It is threaded through in two sets of holes.Common compressed spring 7 can be used in elastic component, while sets of holes are extended transversely through entire handle of a knife 4, sets of holes
Internal outer end is equipped with regulating part, and regulating part is along sets of holes axial movement adjusting the elastic force of compressed spring 7.When regulating part axial direction
Inwardly during movement, its spring energy storage bigger of 7 stress of compressed spring so that cutter claw clamping force is big, otherwise clamping force is small.It is adjusting
During section, it should which two regulating parts synchronize the adjusting of equity, and the clamping force of two cutter claws is avoided to differ and cutter position occurs
Situations such as putting offset or flail knife.Regulating part is generally coordinated using helicitic texture and sets of holes, for example, by using 70 conduct of spring jackscrew
Regulating part is used.
Sets of holes are preferably formed in the end of handle of a knife 4, and the arm of force is longer, can more fully utilize the potential energy of elastic component.Handle of a knife 4
It is equipped with to limit the pressing sleeve 8 of 4 position of handle of a knife at rotation connection with installing plate 3, pressing sleeve 8 is limited in the revolution of two cutter claws
The heart, and make two cutter claws can flexible rotating there will not be apparent play up and down.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the present invention can have various changes, combination and variation.All within the spirits and principles of the present invention, made
Any modification, equivalent substitution, improvement and etc. should be included within scope of the presently claimed invention.
