The specific embodiment
See also shown in Figure 3ly, the present invention discloses a dozen cutter mechanisms 30, and it is provided in a main shaft 40 inside.This main shaft 40 comprise a body 42, one axles 44 organize rotationally be located at body 42 inside axially.One tool-broaching mechanism 50 comprises a pull bar 52 and is fitted in the axial of axle 44 inside movably, and pull bar 52 1 ends connect a jaw 54 in order to clamping one tool rest 56.
So be provided with bearing group for axle 44 can be rotated in axle 44 appearances and 42 groups of body, wherein 46 of clutch shaft bearing groups are at axle 44 1 ends and near tool rest 56, and 48 of one second bearing group are at axle 44 other ends and away from tool rest 56.
See also Fig. 3 and Fig. 4, forging a knife, mechanism 30 comprises a first piston 32, one second piston 34, one first is gone into power space 36 and one second and gone into power space 38, and all dispose and/or be formed on 42 of axle 44 and bodies, and all the position is between the clutch shaft bearing group 46 and second bearing group 48.The concrete composition and the start form of mechanism 30 of forging a knife is as described below.
32 groups of first pistons are located at axle 44 surfaces and near second bearing group 48.One first lock nut 62 locks on axle 44 and the end face of relative first piston 32, and mat one lock nut 62 restriction first pistons 32 are exceedingly towards 48 displacements of second bearing group.34 groups in second piston is located at axle 44 surfaces and position between first piston 32 and clutch shaft bearing group 46.
One first goes into power space 36 is formed between the first piston 32 and second piston 34.First goes into power space 36 can utilize the edge face structure of first piston 32 and second piston 34 relative and form.One first flow 66 is formed in the body 42 and an end and first is gone into power space 36 and communicated.
One second goes into power space 38 is formed between the block face 72 of second piston, 34 end faces and body 42, wherein block face 72 protruding centers to body 42.One second runner 68 is formed in the body 42 and an end and second is gone into power space 38 and communicated.
See also Fig. 3 and Fig. 5, when gas 74 is introduced into second runner 68 and enters second to go into the 38 air pressure strength in power space and will push the direction displacement of second piston 34 towards first piston 32, drive pull bar 52 center rollers 44 simultaneously and produce relative motion and mobile towards first piston 32, thus, jaw 54 draws in and provides clamping to grip tool rest 56.Aforementioned air pressure strength is defined as one second active force 84, and second active force 84 needs to go into 38 beginnings of power space by external world's importing second, and 34 generations push effect to second piston.In addition, according to the principle of gas pressure power, also can import liquid and go into power space 38 in second and form second active force 84 according to this.
See also Fig. 3 and Fig. 6, go into power space 36 when liquid 76 is introduced into first flow 66 and enters first, then oil pressure strength will push second piston 34 away from first piston 32, drive pull bar 52 simultaneously towards the direction displacement away from first piston 32.So jaw 54 just can unclamp and make folder tool rest 56 to be removed.Aforementioned oil pressure strength is defined as one first active force 82, and first active force 82 needs to go into 36 beginnings of power space by external world's importing first, and 34 generations push effect to second piston.
Disclosed first active force 82 of previous embodiment and second active force 84 all can inject first by fluid goes into that power space 38 is gone in power space 36 and second and forms fluid pressure and push second piston 34 to produce displacements, and therefore first goes into power space 36 and second and go into power space 38 and may be defined as cylinder or oil cylinder.And first go into power space 36 and second and go into power space 38 and can change spatial volume because of the displacement of second piston 34.
See also Fig. 7, another embodiment of the present invention is for to go into power space 38 internal configurations, one elastic parts 86 second, and elastic parts 86 1 end in contact block faces 72, and the other end contacts second piston, 34 end faces.When being imported into first, first active force 82 goes into power space 36, then 34 displacements of second piston and elasticity of compression assembly 86; When 82 disappearances of first active force, then the restoring force of elastic parts 86 acts on second piston 34, makes second piston 34 towards first piston 32 displacements.
The restoring force that above-mentioned elastic parts 86 is provided also is defined as second active force.Different with last embodiment is, elastic parts 86 is fixedly arranged on second goes in the power space 38, so second active force of this embodiment is to be placed in second to go into power space 38 but not imported by the external world.
See also Fig. 8, the present invention another more the embodiment of simplifying be configured in first and go into the power space 36 and second piston of going between the power space 38 for keeping, second piston 34 shown in the figure for example, thus, importing or be provided with first goes into power space 36 and second and goes into the relativity face that the active force in power space 38 can act on this second piston 34 respectively and make that pull bar 52 can displacement.The effect that makes the jaw (not shown) produce clamping as for pull bar 52 displacements or unclasp as hereinbefore, so repeat no more.
By the disclosed structure configuration of above each embodiment, the present invention mechanism 30 that will forge a knife is configured in body 42 inside, particularly between the clutch shaft bearing group 46 and second bearing group 48, therefore do not take the space of main shaft 40 ends, do not influence the space usability of toolroom machine fully; The mechanism 30 that forges a knife in addition is not connected the end of axle 44 yet, so the length of axle 44 is increased, when axle 44 high speed rotating, can present better stable dynamic characteristic.
More than be preferred embodiment of the present invention and design drawing, only preferred embodiment and design drawing only illustrate, be not to be used to limit interest field of the present invention, all with equalization technological means or be the interest field that contained of claim content and implementer, all do not break away from category of the present invention and be applicant's interest field.
