The specific embodiment

Below in conjunction with drawings and Examples the technical program is described in further detail.

Please consult Fig. 1-3 together, the cutting tool 100 of first embodiment of the invention comprises tool rest 10, blade 20 and screw 30.

Tool rest 10 is roughly T-shaped, comprises pedestal 12 and vertically extends the first next clamping part 14 from pedestal 12.First clamping part 14 is tabular, and the plane of flattening of this first clamping part 14 is vertical or be basically perpendicular to a surface 122 of this pedestal 12.First clamping part 14 is provided with first holding section 144 away from an end face of pedestal 12, and in the present embodiment, first holding section 144 is a strip groove.The middle position of first clamping part 14 offers a screwed hole 142, is used for cooperating with screw 30 so that blade 20 is fixed in tool rest 10, and the bearing of trend of this screwed hole 142 is vertical or be basically perpendicular to the plane of flattening of this first clamping part 14.

Blade 20 comprise blade 22 and from blade 22 end faces 222 to second clamping part 24 that extends to form away from blade 22 directions, and be arranged on second holding section 26 of blade 22 end faces.This second holding section 26 is used for cooperating with first holding section 144.Second clamping part 24 comprises two parallel and plate bodys 244 spaced apart from each other, and the extension direction of these two plate bodys 244 is vertical or be basically perpendicular to this blade 22 end faces.Second holding section 26 is between two plate bodys.The centre of two plate bodys 244 of second clamping part 24 all offers a screwed hole 242, is used for cooperating so that blade 20 is fixed in tool rest 10 with screw 30.In the present embodiment, second holding section 26 is an elongated projections.

In when assembling, first clamping part 14 of tool rest 10 is inserted between two plate bodys of second clamping part 24, first holding section 144 is engaged with second holding section 26.At this moment, two medial surfaces of the lateral surface of first clamping part 14 and second clamping part 24 are fitted.

Be provided with double positioning structure between tool rest 10 and the blade 20: first clamping part 14 and second clamping part 24 are fixed by clamping mode, and two medial surfaces of the lateral surface of first clamping part 14 and second clamping part 24 are fitted to realize the location; First holding section 144 and second holding section 26 fasten to realize the further location of tool rest 10 and blade 20.Therefore, when being assembled into blade 20 on the tool rest 10, can realize accurate location, thereby improve shear precision, and then improve and produce yield.

Be understandable that first holding section 144 also can be an elongated projections, correspondingly, second holding section 26 is the strip groove.

See also Fig. 4, the cutting tool 100a of second embodiment of the invention and the cutting tool 100 of first embodiment are similar, difference is: the first clamping part 14a of tool rest 10a is two parallel and plate bodys spaced apart from each other, and the second clamping part 24a of blade 20a is tabular.Be provided with the first holding section 144a between two plate bodys of the first clamping part 14a, the end face of the second clamping part 24a is provided with the second holding section 26a, and the second holding section 26a is used for engaging with the first holding section 144a.In the present embodiment, the first holding section 144a is the strip groove, and the second holding section 26a is an elongated projections.

See also Fig. 5-6, the cutter 200 of third embodiment of the invention comprises drive unit 40, be arranged on first cutting tool 50, the base 60 of drive unit 40 and be arranged on second cutting tool 70 of base 60.First cutting tool 50 and second the cutting tool 70 all cutting tool 100 with first embodiment of the invention are identical.First cutting tool 50 comprises that first blade, 502, the second cutting tools 70 comprise that second blade, 702, the first blades 502 and second blade 702 are oppositely arranged.Drive unit 40 is used to drive the direction motion of first cutting tool 50 towards second cutting tool 70, to realize cutting.
