Abstract
The utility model discloses a precisely vernier superhard abrasive hole-machining tool, belonging to an adjustable tool. The public known superhard abrasive vernier hole-machining tool is commonly difficult to obtain the ideal circular degree, and needs the grinding machining; the tool structure is complex; the vernier dimension is difficult to obtain, and needs trial adjustment and trial cut many times, and can not meet the machining requirements of the relatively large hole diameter. The utility model has the advantages that the precise vernier dimension can be realized simply and the service life of the tool is long. The utility model is suitable for producing the hole-machining tool with relatively large hole diameter (for example 50 mm). The tasks are accomplished by an integral type elastic tool body provided with equal divided slots, together with a locking adjusting sleeve and an adjusting cone axis which are arranged on one end and an inner hole of the tool body.
Description
The present invention relates to a kind of accurately aperture knife tool of fine setting of realizing.
Existing general hole processing super hard abrasive cutter is outer adjustable or can not mode two kinds, can not mode super hard abrasive aperture knife tool (Fig. 5), though advantages such as simple in structure, that the cost of charp tool is low are arranged, but during owing to the plating super hard abrasive, be difficult to reach ideal dimensions, both made, also be difficult to reach accurate dimension through reconditioning, thereby be difficult for to realize Precision Machining, and shortcomings such as cutter life is short are arranged.Adjustable super hard abrasive aperture knife tool (Fig. 6) generally has internal taper hole, has one and store elasticity broach shell cutting fluid and chip trough (1) and an axle (2) constitutes by one, and the adjusting of tool dimension is leaned on broach shell to move axially on axle and realized.But because other are different everywhere on elasticity broach shell fluting place elastic pressure and the circumference, thereby cutter can not get desirable garden degree, this kind structure is transmitted the cutting moment of torque by the frictional force of conical surface combination, to the axiality of wall thickness, broach shell and the axle of broach shell, the contact area of the conical surface, strict demand is all arranged, and cutter also will finish grind the broach shell cylindrical under the state of pre-locking.Another kind of adjustable hole processing super hard abrasive cutter such as Fig. 7, Fig. 8.Its complex structure, adjusting inconvenience must just can reach ideal dimensions through repeatedly trying accent, trial cut, and this class cutter often is unsuitable for large scale (more than 25 millimeters) hole processing request again.Though Fig. 8 can obtain bigger adjustment amount, cutter is made difficulty, adjusts also difficulty.
Task of the present invention provide a kind of can be accurate and easy the realization fine setting, be suitable for the fine finishining of larger aperture (10 millimeters to 50 millimeters), long-life super hard abrasive aperture knife tool.
Task of the present invention is by an integral type elasticity cutter hub (5), with by regulating the axis of cone (4), locking regulating sleeve (3), packing ring (2), the micro-adjusting mechanism that button-headed screw is formed is finished, during adjustment, earlier half knob screw is back-outed 3 millimeters, pull out the locking regulating sleeve, as required the locking regulating sleeve is rotated several grooves so that several circles on elasticity cutter hub end face, put down the locking regulating sleeve then, screw half knob screw, just can realize accurate fine setting (Bi 1).
Below in conjunction with accompanying drawing invention is described in further detail.
Fig. 1 is a structure chart of the present invention
Fig. 2 is the locking regulating sleeve
Fig. 3 regulates the axis of cone
Fig. 4 is an integral type elasticity cutter hub
With reference to Fig. 2, the endoporus of locking regulating sleeve is the rectangular opening that the garden chamfering is arranged, and can link to each other with the garden axle through cutting edge on Fig. 3 regulates the axis of cone.Regulate that one section pitch is arranged on the axis of cone is 0.5～1 millimeter screw thread, be meshed with the fine thread of same pitch in the integral type elasticity cutter hub, regulating axis of cone lower end is the tapered section of 1:30 to 1:50, it is deep in the hole of the elastic working section with 1:50 tapering of integral type elasticity cutter hub, the rotation of locking regulating sleeve, drive the rotation of regulating the axis of cone, the rotation of regulating the axis of cone again by the fine thread on it cause integral type elasticity cutter hub on, move down with the awl end of regulating the axis of cone and in the elasticity cutter hub, relatively move, cause the rising of external diameter of elasticity cutter hub active section, contract, thereby realized the adjusting of cutter hub external diameter.
The regulated quantity of cutter hub external diameter is decided by the amount of spin of locking regulating sleeve at cutter hub one end.For ease of the control and regulation amount, have several five equilibrium even bin (it is different to look the cutter hub external diameter, and what external diameter was big can slot more) at an end of the cutter hub that links to each other with the locking regulating sleeve.For example open 10 grooves, when the tapering of regulating the axis of cone one end is 0.75 millimeter for 1:50 pitch, when the locking regulating sleeve rotated a groove at cutter hub one end, cutter hub rose, the amount of contracting is △ d,
△ d=0.75 * 1/10 * 1/50=0.0015 millimeter
When elasticity cutter hub and cone governor between centers had 5 to 7.5 millimeters relative displacements, the cutter hub external diameter can be realized 0.1 to 0.15 millimeter rise sharply most, the amount of contracting.
In order to guarantee elasticity cutter hub circumference evenly rise, contract rigidity with cutter hub, thereby guarantee to adjust size stability and machining accuracy, the present invention has the groove of five equilibrium on integral type elasticity cutter hub, and takes thicker wall thickness, for example when the cutter hub external diameter is 15 millimeters, adopt 5 millimeters wall thickness.
The cutter that uses the present invention to make, owing to adopt the integrated elastic structure of the cutter body, strain is little, the adjustable dimension amount is little, but the every adjusting that can make cutter by its nominal size the different grades of tolerance, samely just can process the hole of same nominal size different accuracy grade to cutter, tool specification, generalization degree are improved greatly.
The cutter that uses the present invention to make, can check tool dimension without measurer, only need are regulated cutter by the requirement of the size of workpiece hole, thereby not only can avoid measurer to wear and tear, but the very high qualification rate of holding workpiece also, because good, the dimensionally stable of cutter rigidity, thereby can reduce the self check of operation and special inspection time.
The cutter that uses the present invention to make can be realized fine adjustment easily, thereby can shorten the processing request that processing also can realize high geometric accuracy, best bright finish non-cutting time.
The present invention is applicable to and makes 10～50 millimeters aperture knife tools.
