Description
Technical field
The present invention relates to metal cutting process field, particularly relate to a kind of cutting tip.
Background technology
In intermetallic composite coating especially hole machined process, the diameter of cutter directly affects the processing dimension of product, along with more and more higher to the dimension precision requirement of processing work, the tool diameter of fixed structure is non-adjustable, thus must possess the dimensional accuracy that the very high accuracy of manufacture just can reach institute's processing work, very high requirement is proposed to the accuracy of manufacture of cutter itself.
In order to improve the machining accuracy of cutter, more adjustable tools has been there is in prior art, as Chinese patent literature CN1438929A discloses a kind of position adjusting mechanism for the blade in chip removing machining tool, chip removing machining tool is preferably milling cutter, this position adjusting mechanism comprises the first hole, this first hole is recessed in the cutter body be connected with the tool rest for installing blade, also includes the lining of slit, and this lining is arranged in the first hole, also comprise the adjustment screw that head has external conical surface feature, this adjustment screw loads in lining, formed between the top and the area supported of cutter body of this lining deflection against, this area supported is arranged to be connected with the first hole, but the design of this guiding mechanism anti-rotation is also unreliable, is difficult to ensure the accurate of installation site, lining is fixedly installed in cutter body and relies on merely adjustment element generation elastic deflection itself is realize blade position adjustment, therefore larger adjustment amount places one's entire reliance upon and adjusts the larger elastic deformation amount of element itself, consequence easily causes adjustment element elastic to lose efficacy, or service life reduces, additionally by the mode of adjustment screw conical surface press-in lining taper hole, adjustment process can force adjustment element taper hole outside and adjustment screw itself that elastic deformation occurs, therefore the fact is that this guiding mechanism adjustment amount is confined to very little scope, just use the cutter of blade regulating device, no matter require very high for cutter itself or the accuracy of manufacture of guiding mechanism and homogeneity of product, to a certain degree increase product manufacturing difficulty.
Another Chinese patent literature CN 1596169A discloses a kind of instrument for going chip to process, and comprising: matrix, for the blade bearing of replaceable cutting inserts, the guiding mechanism contiguous by blade bearing can be adjusted, this guiding mechanism comprises two clamps, front surface can be pressed onto on the rear surface of cutting tip by the first clamp, and pressure surface backward can be pressed onto at least one fixed support surfaces on matrix by the second clamp, the effect of individual wedge element is had between two clamps, its objective is if needs, by driving wedge element to be separated two clamps between two clamps, the second clamp is made to be pressed onto in fixed support surfaces, first clamp moves from the home position direction forward of secondary supporting surface and extrudes cutting tip simultaneously, it is characterized in that, except primary fixed support surfaces, matrix is at least formed a secondary fixed support surfaces, on first clamp towards the rear to pressure surface can be pressed on secondary supporting surface, thus, when cutting tip is arranged on blade bearing, guiding mechanism can repeat adjustment between two kinds of different functional statuses, two different functional statuses are: the first state, by the first front surface pressure of clamp on cutting inserts same time pressure surface be pressed on secondary supporting surface, first clamp clamps cutting tip at home position, thus, second clamp due to not yet in effect be pressed onto on primary supporting surface inoperative, second state, between clamp after initial wedging wedge element, second clamp is pressed onto on primary supporting surface, between cutting tip locomorphic stage, first clamp passes through the extra wedging of wedge element, can move up from secondary supporting surface in home position side forward, thus, no matter the state of guiding mechanism how, first front surface close contact of the total and clamp in cutting tip and rear surface thereof, there is following defect in this guiding mechanism: one, guiding mechanism mounting means is comparatively complicated, need to be press-fited by guiding mechanism by extra specific purpose tool that to be fixed to matrix groove inner, therefore be difficult to ensure the accurate of installation site, two, the assembling mode that between guiding mechanism and matrix, interference fit is fixed is unfavorable for the convenient replacing after guiding mechanism inefficacy, easily causes scrapping of whole cutter because of the inefficacy of guiding mechanism, three, guiding mechanism relies on merely adjustment element generation elastic deflection itself to come to be realize blade position adjustment, therefore larger adjustment amount places one's entire reliance upon and adjusts the larger elastic deformation amount of element itself, consequence easily causes adjustment element elastic to lose efficacy, or service life reduces, four, by the mode of adjustment screw wedge-shaped surface wedging guiding mechanism axis hole, desirable result is that slit both sides clamp produces roughly equal elastic deformation, and in fact the second clamp be pressed against all the time fixed support surface cannot according to desirable trend generation elastic deformation, therefore can force adjustment element taper hole outside and adjustment screw itself that elastic deformation occurs during adjustment, therefore the fact is that this guiding mechanism adjustment amount is confined to very little scope, five, under instrument adjustment state, between cutting tip to matrix, Stress transmit needs by the first clamp, wedge-shaped element and the second clamp, for the guarantee of quality of fit between wedge-shaped element and parts, need to be realized, so increase the manufacture difficulty of tool body and guiding mechanism to a certain extent by the accuracy of manufacture of raising instrument itself and guiding mechanism.
