Description
Technical field
The utility model relates to a kind of cubing for groove.
Background technology
Indexable insert tip, throw away tip refers to can the polygonal insert mechanically clamping cutter on knife bar or cutter hub that uses of transposition, by pre-processed and with the polygonal insert of several cutting edges, the method clamping with machinery is clamped on cutter hub.In machining, when after a blade tip blunt, use other blade tip by after blade transposition, this blade is no longer refaced after being worn out.The blade of most indexable tool adopts carbide alloy, also has and adopts pottery, polycrystal cubic boron nitride or polycrystalline diamond.
Indexable cutter hub and cutterhead are connected and often adopt side keyway structure, and passing hole inner bolt comes fastening.Cutter hub hole end surface centre has the convex key of side keyway and interchangeable termination to coordinate, and the aperture of side keyway is less, and precision prescribed is high, groove milling or slot grinding in-process gaging more difficult, past conventional slide calliper rule add gauge block cushion block indirect inspection and detect, and are inconvenient to operate, also inaccurate.
Utility model content
The utility model is intended to provide a kind of little hole slot symmetry degree gauge, measuring the symmetry of aperture keyway with precise and high efficiency.
Little hole slot symmetry degree gauge in this programme, comprise the measuring basis plate that bottom is plane, the lower surface of measuring basis plate has the end face of keyway on positioning workpieces, the lower surface of measuring basis plate is provided with the convex key for stretching into detected workpiece small hole groove, the width of convex key is less than the width of detected workpiece small hole groove, the degree of depth of convex key is less than the degree of depth of detected workpiece small hole groove, measuring basis plate is connected with dial framework, dial framework is connected with lever indicator, the relative position of dial framework and lever indicator is fixed by showing to adjust screw, measuring basis plate is provided with groove, the gage outfit of lever indicator is through groove.
When using this cubing, in first time measures, with the end face detected workpiece in lower surface location of measuring basis plate with aperture keyway, convex key on measuring basis plate is stretched in the keyway on detected workpiece simultaneously, facade corresponding to keyway is pushed against with the facade of convex key side, then by the gage outfit of table adjustment screw adjustment (adjusting) lever dial gauge, the gage outfit of lever indicator is just dropped on the mesopore inwall of detected workpiece, and records reading.Then in the horizontal direction 180 ° upset cubings, make cubing be positioned on another facade of workpiece keyway in the same way, by lever indicator second time reading, keyway symmetry is evaluated in the change namely by twice dial gauge reading.
Further, dial framework is provided with cylindrical void, and dial framework is connected on measuring basis plate by the trip bolt penetrating cylindrical void.The relative position of dial framework on measuring basis plate can be adjusted by loosening after trip bolt, then by trip bolt with fixing.
Further, dial framework is provided with vertical locating slot, and lever indicator adjusts screw attachment on dial framework by table.In locating slot, the position of lever indicator can be adjusted up and down, to adapt to the needs measured based on above-mentioned feature.
Further, described convex key is two, and the gage outfit of lever indicator is between two convex keys.Two convex keys can be positioned in two keyways symmetrical on workpiece simultaneously, improve the accuracy of locating in measuring process.
Accompanying drawing explanation
Fig. 1 is the cross-sectional schematic of the utility model embodiment.
Fig. 2 is the schematic top plan view of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: the workpiece that l-dial framework, 2-table adjustment screw, 3-lever indicator, 4-dial framework adjustment trip bolt, 5-measuring basis version, 6-are detected.
Embodiment is substantially as depicted in figs. 1 and 2: detected workpiece 6 is put for axially perpendicular, its upper surface is level, the lower surface of measuring basis plate level drops on the upper surface of workpiece, two convex keys below measuring basis plate 5 fall into and are positioned in two keyways on workpiece, being resisted against on right side facade corresponding to keyway tightly of the facade on the right side of convex key.
The below left part of dial framework 1 is provided with cylindrical void, position corresponding on measuring basis plate 5 is provided with tapped through hole, dial framework 1 is connected on measuring basis plate 5 by dial framework adjustment trip bolt 4, and can adjust the horizontal relative position of dial framework 1 and measuring basis plate 5 by unclamping dial framework adjustment trip bolt 4.The top right part of dial framework 1 is provided with vertical locating slot, the right of locating slot is empty, lever indicator 3 is fixed on dial framework 1 by table adjustment screw 2, by the degree of tightness of table adjustment screw 2, can adjustment (adjusting) lever dial gauge 3 relative to the position relationship such as angle, height of dial framework 1.The gage outfit of lever indicator 3 should be set to just be resisted against on workpiece 6 inner hole wall and be advisable, and now the reading of lever indicator is within its range.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
