Floating taper sleeve centering clamp

Abstract

The invention provides a floating taper sleeve centering clamp. The floating taper sleeve centering clamp comprises a base, a centering device, a positioning device and a clamping device, wherein thepositioning device is arranged on the upper surface of the base; the centering device is vertically arranged on the upper surface of the base and is arranged on the inner side of the positioning device; the centering device comprises a rotating shaft, a centering seat, a spring, a taper sleeve and a pressing block; the rotating shaft, the centering seat, the spring, the taper sleeve and the pressing block are coaxial; the rotating shaft is arranged at the upper end of the base and is perpendicular to the upper surface of the base; the centering seat is arranged at the upper end of the rotatingshaft; the spring is nested at the upper end of the centering seat; the outer side of the taper sleeve is a conical surface and is axially provided with a through hole; the spring is arranged in thethrough hole of the taper sleeve; the upper end of the centering seat penetrates through the taper sleeve; and the pressing block is arranged at the top end of the centering seat. a motor positioningseam allowance and the floating taper sleeve cooperate to center, so that the perpendicularity allowance between a motor joint surface and a lower joint surface is ensured; a thrust oil cylinder is used for aligning so as to limit the rotation freedom degrees of the workpieces; joint screw counter bores of the motor are symmetrical about the center of the clamp tool; and machining precision and efficiency of the workpieces are greatly improved.

Description

technical field [0001] The invention relates to the field of machine tool fixtures, in particular to a centering fixture. Background technique [0002] The centering clamping mechanism is a clamping mechanism that realizes the centering positioning and clamping of the workpiece at the same time, that is, during the clamping process, it can keep the workpiece symmetrical with respect to a certain axis or a certain plane of symmetry. In the case of uncertain positioning hole size, the centering mechanism is often not accurate. [0003] The original process on the motor seat: Alignment on the ordinary horizontal milling machine to complete the milling of the motor joint surface and the square outline; external alignment and then milling the joint surface of the stop block; end milling and milling the joint surface of the cover plate; The cover plate is used as the datum plane to mill the joint surface of the workpiece and the workpiece below; the joint surface is used as the p...
