Abstract
The utility model provides a quick-changing universal centering auxiliary device which is used on a machinable machine tool and uses the aperture positioning to process apertures. The utility model is especially suitable for the reaming and tapping and is composed of a taper shank sliding sleeve, a connecting shaft arranged on the taper shank sliding sleeve, a double-connection connecting sleeve, a bearing, a bearing sleeve, a rapid-clamping-release device. After a cutting tool is arranged, the utility model can automatically center and plumb. When the quick-changing universal centering auxiliary device processes, the clamping error of a work piece in the processing can be eliminated. The coaxiality of the work piece processing can be increased, and the unilateral phenomena of reaming and tapping are solved. The utility model has the best effects on the thread processing and can ensure the concord of the thread pitch and the width at the tooth tip.
Description
The utility model relate to a kind of on the machined lathe, use with the attaching of aperture setting processing aperture, particularly fraising, tapping attaches.
A kind of unsteady tapping clamp of the quick change with aperture setting processing aperture (for example boring, thread tapping and fraising) that uses on the machined lathe is arranged now, this anchor clamps can only be X, the centering of Y-axis both direction in length and breadth, when a workpiece that needs tapping or dumpling hole during through last tapping of multiple clamping or fraising, because there is error in clamping, the hole that screw thread that the unsteady tapping clamp of employing quick change processes or dumpling are crossed just can not guarantee axiality.Because this anchor clamps can not self-centering on the Z axle.
The purpose of this utility model provides a kind of universal centering of using of quick change with aperture setting processing aperture and attaches on the machined lathe, promptly add man-hour can self-centering on X, Y, Z axle.
Technical solution of the present utility model is such: it comprises a taper shank sliding sleeve, in the installing hole of taper shank sliding sleeve, a connecting axle is housed by pivot pin, connecting axle is provided with two adapter sleeve that connects, two adapter sleeves that connect are connected by connecting pin with connecting axle, two cylindricals that connect adapter sleeve are provided with a bearing, be with a bearing holder (housing, cover) on the bearing, two endoporus that connect adapter sleeve also are provided with an axle collar connecting rod that has thimble, axle collar connecting rod is connected with two covers that connect in succession by connecting pin, be connected with two covers that connect in succession by connecting pin in the screwed hole of axle collar connecting rod, by the elasticity spiral shell card that is threaded, be provided with a tapering centring sleeve that has three balls in the hole of elasticity spiral shell card successively in the screwed hole of axle collar connecting rod, spring and cubic fixture block.
Attaching that the utility model provides can be cut cutlery (for example screw tap, reamer etc.) by quick-clamping, can self-centering, vertical after cutlery is loaded onto.Add the clamping error that to eliminate the workpiece work in-process man-hour, improve the axiality of workpiece processing, solve dumpling hole, the monolateral phenomenon of tapping.Be used for screw thread processing effect the best, can guarantee pitch and tooth top width unanimity.
