Embodiment
below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be understood by those skilled in the art.
figure 1 shows that a kind of coating cutter sweep of the present invention, this coating cutter sweep is a kind of instrument of the drawing sample for the preparation of coating adhesion test.
shown in composition graphs 1, this coating cutter sweep comprises rotation axis 1, cutter head assembly 2, detent mechanism 3.
rotation axis 1, is rotated as direct current generator, D.C. electric drill etc. drive by actuating unit.Rotation axis 1 comprises body 11, from body 11 along perpendicular to the outward extending installation portion 12 of body 11 direction of axis line, in the present embodiment, body 11 and installation portion 12 are one of the forming.The top of rotation axis 1 body 11 connects with the output shaft etc. of direct current generator.
cutter head assembly 2, arranges in pairs and lays respectively at the relative both sides of drawing part 4.Cutter head assembly 2 comprises the handle of a knife 21 that can slide up and down to be connected to rotation axis 1, the cutter head 22 being arranged on handle of a knife 21 bottom, the setscrew nut 23 be sheathed on handle of a knife 21, is arranged at the first spring 24 between installation portion 12 and handle of a knife 21.Particularly, the installation portion 12 of rotation axis 1 offers and cutter head 22 assembly 2 first through hole one to one, handle of a knife 21 is located in the first through hole slidably, setscrew nut 23 is set in handle of a knife 21 top and is positioned at above through hole, handle of a knife 21 bottom has step surface 211 upward, first spring 24 top is located between this step surface 211 and installation portion 12, cutter head 22 is removably connected on the bottom of handle of a knife 21 by cutter head fixed screw 25, the setting and cutter head 22 phase of paired cutter head 22 assembly 2 maintains an equal level, distance between each cutter head 22 and the axial line of body 11 is all equal.
detent mechanism 3, moves for limiting drawing part 4.Detent mechanism 3 comprises bearing 31, inner core 32, urceolus 33, locating part 34 and jump ring 36.The inner ring of bearing 31 is fixedly connected with the body 11 of rotation axis 1 by screw, and the outer ring of bearing 31 is fixedly connected with inner core 32.Inner core 32 and urceolus 33 cylindrical shape all substantially in hollow, urceolus 33 can slide up and down to be sheathed on inner core 32.Drawing part 4 comprises superposed drawing part 41 and is positioned at the binding part 42 of bottom, adopts aluminium ingot as drawing part 4 in the present embodiment.The lower surface of binding part 42 for the coating to be measured that bonds, the lower surface of binding part 42 be circular and this center of circle on the axial line of body 11, the center line of inner core 32 and the axial line of body 11 coincide setting.Distance between the axial line of cutter head 22 and body 11 should equal or slightly larger than this radius of a circle, so that when cutting, the side that cutter head 22 can be adjacent to binding part 42 cuts coating.
the spatial accommodation for holding drawing part 41 is formed in inner core 32.The bottom of inner core 32 offers multiple second through hole 321, and multiple second through hole 321 is arranged at equal intervals along the circumferencial direction of inner core 32, and locating part 34 is multiple and is arranged on actively respectively in the second through hole 321.Drawing part 41 has depression 411, and extended second through hole 321 of a part of locating part 34 also snaps in depression 411, thus is limited in spatial accommodation by drawing part 41.Adopt steel ball as locating part 34 in the present embodiment, the hole wall of the second through hole 321 is inclined-plane, and namely the hole wall of the second through hole 321 tilts to extend in the mode gradually away from the center line of the second through hole 321 along from inner core 32 towards the direction of urceolus 33.Jump ring 36 is removably connected between inner core 32 bottom and urceolus 33 bottom.
when jump ring 36 is connected between inner core 32 and urceolus 33, the inwall of urceolus 33 bottom covers the second through hole 321, steel ball is subject to the stop of urceolus 33 and is restricted in the second through hole 321, and a part for steel ball is extruded the second through hole 321 and the depression 411 extending to drawing part 41 is sentenced and snapped in depression 411, thus be limited in spatial accommodation by drawing part 41, and then drawing part 4 is stoped to move horizontally.After jump ring 36 is dismantled, upward sliding urceolus 33, when inwall to urceolus 33 bottom is positioned at above the second through hole 321, along with the disappearance of power kept out by urceolus 33, steel ball glides along the hole wall of the second through hole 321 and departs from the second through hole 321 under self gravitation effect, along with steel ball skids off the second through hole 321, drawing part 41 is released.The second spring 35 of the reset force for providing slide downward to urceolus 33 is also provided with between urceolus 33 top and inner core 32.
the course of work of the present invention is as follows: coating is coated on after on coated article body, drawing part 4 to be positioned in layer and its lower surface and coating are fitted, according to coating thickness synchronous axial system setscrew nut 23 to adjust the height of cutter head 22, the inner core 32 of detent mechanism 3 is placed on steel ball after on drawing part 41 and positions drawing part 4, now the lower end of cutter head 22 is stretched in coating to connecting with coated article surface, start actuating unit, rotation axis 1 drives each cutter head 22 assembly 2 to rotate relative to drawing part 4, the side that cutter head 22 is adjacent to drawing part 4 binding part 42 cuts coating, after on portion 42 to be bonded lower surface, coating is cut at least one circle, drawing part 4 discharges by upward sliding urceolus 33, obtained described drawing sample.
in pairs and be symmetrical arranged, handle of a knife 21 can be slided up and down to be arranged on installation portion 12 and to be adjusted by setscrew nut 23 cutter head 22 assembly 2, and the thickness according to tested coating regulates depth of cut easily by regulating the height of cutter head 22, flexible and convenient to use; Arrange the first spring 24 between handle of a knife 21 and installation portion 12, cutting pressure relies on the first spring 24 tension force to keep, when the out-of-flatness of coated article surface, first spring 24 allows cutter head about 22 fine motion, avoid damaging coated article surface, the even cutting to coating can be realized, use safety; Cutter head 22 is detachably replaced.Drawing part 4 can be located by detent mechanism 3 fast, ensure that the accuracy of cutting, and ensures the flexibility of revolution of stability and the cutter head 22 of locating simultaneously.Can connect the various actuating unit such as direct current generator, D.C. electric drill by rotation axis 1, it is time saving and energy saving to cut.Significantly reduce the impact of human factor, to ensure that the drawing sample prepared meets test request.
above-described embodiment for technical conceive of the present invention and feature are described, is only a kind of preferred embodiment, its object is to person skilled in the art and can understand content of the present invention and implement according to this, can not limit protection scope of the present invention with this.The equivalent transformation that all Spirit Essences according to the present invention are done or modification, all should be encompassed within protection scope of the present invention.
