Abstract
The utility model relates to a rotatable automatic positioning clamping device of cutter with the pin oblique type. The structure of the clamping device is that a regulating nut is tightened into the thread hole with the off-center cone hole on the cutter body, and the pin with the globular bulge is tightened into the thread hole of the regulating nut. Under the actions of the regulating nut and the off-center cone hole on the cutter body, the shaft line of the pin generates an a-angle displacement corresponding to the shaft line of the regulating nut. The pin applies a clamping force and a positioning force at the side of the installing and clamping hole of the blade to ensure the stable and reliable cutting of the cutter. The utility model has the advantages of simple device and easy fabrication and is suitable to the recutting under the impact load.
Description
The utility model relates to the automatic positioning clamping device of a kind of pin clino-axis type index tool.
The indexable tool clamping device has basic patterns such as last pressure type, taper formula and lever pin formula both at home and abroad at present.
Last pressure type: active force is pressed on blade on the cutter hub from the top down.
The taper formula: by rotary screw, promote voussoir and move down, press to blade on the alignment pin that is arranged in blade clamping hole on the inclined-plane of voussoir.
The lever pin formula: by rotary screw, make the swing of L type lever pin, the pivot pin that is arranged in blade clamping hole is pressed on blade on the locating surface of cutter hub.
Though last pressure type is simple in structure, and is easy to manufacture, the housing screw head hinders chip removal sometimes, also scratched by smear metal easily, and wearing and tearing, the positioning accuracy of blade is lower.Taper formula and lever pin formula, blade positioning accuracy height, but complex structure, manufacturing cost height.
In addition, analyze from the action direction of active force, the active force of last pressure type is a power vertically downward, and the active force of taper formula and lever pin formula is a side force.Above-mentioned three kinds of patterns all do not have fine solution to act on the problem of two component on the blade simultaneously, promptly act on the vertical stress component on the cutter hub supporting surface, and the problem that acts on the horizontal component of cutter hub locating surface.
The purpose of this utility model is a kind of indexable tool clamping device that clamping is firm, the location is accurate, simple in structure that two component (clamping force and detent force) are arranged on the blade that acts on simultaneously of design.
Technical solution of the present utility model is:
The indexable tool clamping device is made up of the screwed hole of band centering taper hole on pin, adjusting nut and the cutter hub of dribbling shape projection.Be characterized in: adjusting nut is screwed in the screwed hole of band centering taper hole on the cutter hub, and the pin of dribbling shape projection is screwed in the screwed hole of adjusting nut; The adjusting nut lower end has the inner polygon hole, and the adjusting nut external screw thread is left-handed, and internal thread is dextrorotation; The pin of dribbling shape projection is by pin, and hemisphere jut and screw thread three parts are formed, and the pin of dribbling shape projection has the gap with cooperating of adjusting nut screwed hole, allows the axis generation α angular displacement of the axis of pin with respect to adjusting nut; The center of cutter hub upper screwed hole does not overlap with the center of taper hole, and the line of crossing two centers is perpendicular to the cutter hub locating surface, or divides the angle of locating surface equally.
The operation principle of pin clino-axis type indexable tool clamping device is as follows: when being rotated down adjusting nut, pin is under the effect of centering taper hole on adjusting nut and the cutter hub, when moving down, again to being displaced sideways, because pin has the strain of gap and pin with cooperating of adjusting nut screwed hole, make the axis of pin produce the α angular displacement, applied on the side of pin in blade clamping hole and can be decomposed into the clamping force that acts on vertically downward on the cutter hub supporting surface and horizontal side to such two component of detent force that act on the cutter hub locating surface with respect to the axis of adjusting nut.Along with the rotation adjusting nut moves down, α contends cumulative adding, and acts on clamping force and also increase gradually of detent force on the blade, guarantees that blade clamps firmly, the location is accurate.When rotating up adjusting nut, α contends decrescence few, so that clamping force and detent force that pin acts on the blade are eliminated, can change blade easily or make the blade transposition.
This shows that this utility model is simple in structure, and is easy to manufacture, blade transposition or replacing are rapidly convenient, and it is reliable and stable to cut pin, is not only applicable to light, medium-sized cutting, also is applicable to the heavy cut under the shock loading.
