It is provided with the mounting groove of an inclination, described grip block is provided with a draw-in groove at described mounting groove at one angle；
Cutter head, the fixed part of described cutter head is cuboid, is provided with two screw holes, this two screw holes in fixed part
It is crossed as " ten " font, described fixed part is installed in described mounting groove by screw；The work department of described cutter head is taper, institute
The point stating the work department of cutter head is inlaid with ball-like diamond；
L-shaped pressing plate, one end of described L-shaped pressing plate is located in described draw-in groove, and the other end is pressed on the fixed part of described cutter head,
And be screwed on described grip block.
It is further that the angle of inclination of described mounting groove is 45 °.
Compared with prior art, the beneficial effects of the utility model are：
1. the building block of this cutter is less, and structure is simple；
2. cutter head is screwed on grip block, and is reinforced with L-shaped pressing plate, and cutter head is difficult in process
Rock；
3. in cutter head, criss-cross screw hole is determined cutter head and can be able to be fixed in mounting groove with any one face, just
In assembling；
4. this cutter can reach the minute surface rolling carrying out inwall in the endoporus of part, due in the clamping with equipment for the cutter head
The heart staggers a certain distance, and therefore this cutter can carry out the minute surface rolling of macropore inwall.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe.
Referring to a kind of endoporus minute surface diamond rolling depression cutter shown in Fig. 1 and 2, including L-shaped knife bar 1, connecting post 2, grip block
3rd, cutter head 4 and L-shaped pressing plate 5.L-shaped knife bar 1 is made up of a transverse arm and a upright arm, and cross arm free end bottom has opened up one
Circular counter bore 1a, has opened up a horizontal pin shaft hole 1b, has been mounted with a bearing pin 6 in pin shaft hole in transverse arm；Pin shaft hole and circle
Shape counterbore connects.One end of connecting post 2 is provided with through hole 2a, and this end is inserted in circular counter bore, and bearing pin 6 passes through from through hole and will connect
Connect post 2 to be fixed in L-shaped knife bar 1.Referring to Fig. 3, grip block 3 is fixedly connected the opposite side of post 2, and grip block 3 is square, grip block
It is provided with a mounting groove 3a tilting 45 °, grip block 3 is provided with a draw-in groove 3b at mounting groove at 3 angle.Ginseng
See Fig. 4, the fixed part of cutter head 4 is cuboid, is provided with two screw hole 4a, this two screw holes are crossed as in fixed part
" ten " font, fixed part is installed in mounting groove by screw；The work department of cutter head 4 is taper, the tip of the work department of cutter head 4
Portion is inlaid with ball-like diamond 4b；One end of L-shaped pressing plate 5 is located in draw-in groove, and the other end is pressed on the fixed part of cutter head 4, and leads to
Cross screw to be fixed on grip block 3, L-shaped pressing plate 5 is reinforced to cutter head 4 so that cutter head 4 is difficult to rock in process.
In cutter head 4, criss-cross screw hole is determined cutter head 4 and can be able to be fixed in mounting groove with any one face, just
In assembling.This cutter can reach the minute surface rolling carrying out inwall in the endoporus of part, due to the Clamping Center of cutter head 4 and equipment
Stagger a certain distance, and therefore this cutter can carry out the minute surface rolling of macropore inwall.
In processing, part rotates, cutter remains stationary state.The diamond of cutter head 4 is pressed on part inwall, to its table
Face applies certain pressure, makes part coating metal produce Plastic Flow, is filled in the indentation trough of original residual, and reaches
Piece surface roughness value reduces.Due to rolled coating metal plastic deformation, make textura epidermoidea's cold hardening and crystal grains fine, shape
Become fine and close threadiness, and form residual stress layer, hardness and intensity improve, thus improving the wearability of piece surface, resistance to
Corrosion and conformability.
And, there is in grip block the function of adjusting itself clamp pressure and connecting post between.
