Specific embodiment
Technical scheme is described in further detail below in conjunction with the accompanying drawings.
As Figure 1-3, the present invention is used for the clamping device of fixing rotatable blade, including tool rest 1, holder 3, clamping
Bolt 2, compression spring 4.Tool rest 1 is provided with the indexable insert tip, throw away tip installation portion 6 and bolt mounting holes 7 of indexable insert tip, throw away tip 5, bolt peace
The dress epimere of hole 7 is accommodating hole 8, and hypomere is thread segment 17, and indexable insert tip, throw away tip 5 is placed on tool rest 1.Holder 3 is placed on tool rest 1
Side, holder 3 is provided with through hole 13, and the lower end of through hole 13 is compression spring accommodating hole 12, and compression spring 4 is sheathed on fishbolt 2
On, and between tool rest 1 and holder 3, compression spring 4 is placed in accommodating hole 8.The rear end of holder 3 is provided with and connects with tool rest 1
Holder 3 coordinate inclined plane 9, holder 3 coordinates the both sides of inclined plane 9 to be provided with the rear protuberance for extending inwardly downward for a pair
14, the rear end of tool rest 1 is provided with the tool rest 1 that connects with holder 3 and coordinates inclined plane 9, tool rest coordinate inclined plane 9 be provided with a pair it is inside
The containing groove 10 for extending downwardly, when clamping device clamps indexable insert tip, throw away tip 5, rear protuberance 14 is placed in containing groove 10,
By the cooperation between rear protuberance 14 and containing groove 10, bootable holder 3 along containing groove 10 relative to tool rest 1 backward
Mobile and spacing to holder 3 in clamping blade 5, limitation holder 3 produces rotation when clamping or unclamping blade, makes
The clamping of blade is more firm, and positioning more precisely, improves the precision of blade resetting.Fishbolt 2 is placed on through hole 13
In the accommodating hole 8 of bolt mounting holes 7, and it is threadedly coupled with the thread segment 17 of bolt mounting holes 7, the epimere of fishbolt 2 is
Head, head is down the slightly smaller column part of diameter, and column part extends to bottom end face for threaded portion, fishbolt 2
Head diameter is more than the diameter of through hole 13 of holder 3, and column part diameter is tightening fishbolt less than the diameter of through hole 13
When, the upper surface of the top surface higher than holder 3 of the head of fishbolt 2, this set causes to be deposited between column part and through hole
In specific gap, so as to ensure that holder 3 will not be rotated easily when fishbolt 2 is tightened.In the present embodiment, holder
Rear protuberance 14 on 3 is in square shoulder shape, and the containing groove 10 on tool rest 1 is strip, and the two length direction is pressed from both sides with holder
Moving direction during tight indexable insert tip, throw away tip is consistent, and rear protuberance 14 meets 0.15mm with the magnitude relationship of containing groove 10<
W-L<0.5mm, and 0.5mm<L1-W1<1mm, wherein W1It is the width of rear protuberance, W is the distance between a pair rear protuberances,
L1It is the width of containing groove, L is the distance between a pair of containing grooves.Protuberance 14 and containing groove after this set guarantee
10 keep specific matching relationship, and when the fastening indexable insert tip, throw away tip 5 of fishbolt 2 is screwed, the rear protuberance 14 of holder 3 is placed in
In containing groove 10, therefore, even if under the frictional force effect of the head of fishbolt 2, holder will not also be produced and deflected
Or rotate, but containing groove 10 in strip can allow for the subsequent protuberance 14 of holder 3 and be moved back by relative to tool rest 1 again
It is dynamic, can effectively guide holder 3 to be accurately positioned indexable insert tip, throw away tip 5, realize the accurate clamping of indexable insert tip, throw away tip 5.Holder 3
Front underside is flat.
During experiment, when indexable insert tip, throw away tip 5 is installed on into clamping device for fixing rotatable blade 5 of the invention, will
Compression spring 4 is placed in the accommodating hole 8 of bolt mounting holes 7, holder 3 is placed in into the top of tool rest 1, and compression spring 4 is placed in
In compression spring accommodating hole 12, then the thread segment 17 that fishbolt 2 is passed through holder 3 and compression spring 4 and bolt mounting holes 7
Lifting status as shown in the figure is engaged to, indexable insert tip, throw away tip 5 is placed in indexable insert tip, throw away tip installation portion 6.Gradually it is screwed into fishbolt
2, the head of fishbolt 2 gradually pushes holder 3, and compression spring 4 is clamped by compression, and the rear protuberance 14 of holder 3 is placed in
In the containing groove 10 of tool rest 1, while the front underside portion of holder 3 contacts with the positioning top surface of indexable insert tip, throw away tip 5, now press from both sides
Holder 3 in gripping member 3 coordinates inclined plane to coordinate inclined plane to contact with the tool rest on tool rest 1, and in the process, holder 3 exists
Under the containing groove 10 of tool rest 1 and the fiting constraint of rear protuberance 14, produce along containing groove length direction relative to tool rest 1 can
The installation portion of transposition blade 5 movement backward, while limited and moving or only producing negligible along the width of containing groove 10
, small displacement and deflection.Continue to tighten fishbolt, now holder 3 is produced in the case where holder coordinates inclined plane 9 to constrain
Raw movement backward, downward and a small amount of elastic deformation, make the lower surface of the front end of holder 3 to the positioning top surface of indexable insert tip, throw away tip 5
Downward pressure is produced, relative to other tool clamping systems, the clamping device for fixing rotatable blade 5 of the invention has
Wider purposes and blade Rotational accuracy.Further tighten fishbolt 2, the elastic deformation increase of holder 3, the folder of generation
Holding force increases, and the one side of final indexable insert tip, throw away tip 5 is adjacent to the side wall of indexable insert tip, throw away tip installation portion 6, indexable insert tip, throw away tip 5
Positioning bottom surface 16 is close to installation portion bottom surface, realizes firm clamping of the clamping device to indexable insert tip, throw away tip 5.Indexing uses indexable
Before blade or replacing indexable insert tip, throw away tip, indexable insert tip, throw away tip need to be unloaded from tool rest 1, unscrew fishbolt 2, in compression spring
Under the elastic force effect upward along the axis of fishbolt 2 produced by 4, holder 3 is gradually lifted, and the holder of holder 3 is matched somebody with somebody
Close inclined plane coordinates inclined plane 9 to depart from the tool rest of tool rest, and rear protuberance 14 is acted on the mutual cooperation of containing groove 10, holder
3 are lifted away to state shown in figure, are now capable of achieving the indexing of indexable insert tip, throw away tip 5 or change.In the process, in containing groove 10
Under the elastic force effect of the mating reaction of rear protuberance 14 and compression spring 4, the double swerve of holder 3 can be efficiently avoid
Or rotated around fishbolt 2, and, indexable insert tip, throw away tip 5 can be capable of achieving more in the case of fishbolt 2 of not exclusively outwarding winding
Change and indexing, save the replacing construction of blade, improve processing efficiency.
Above-described embodiment is only the preferred embodiment of the present invention, it is noted that for one of ordinary skill in the art
For, on the premise of principle of the invention is not departed from, some equivalents can also be made, these equivalents are regarded as
Protection scope of the present invention.
