A Floating Taper Sleeve Centering Fixture

Abstract

The invention provides a floating taper sleeve centering fixture, which includes a base, a centering device, a positioning device and a clamping device, the positioning 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 Inside the positioning device, the centering device includes a rotary shaft, a centering seat, a spring, a taper sleeve and a pressure block. The rotary shaft, a centering seat, a spring, a taper sleeve and a pressure block are coaxial. On the upper surface of the base, the centering seat is arranged at the upper end of the rotary shaft, and the spring is nested at the upper end of the centering seat. The upper end passes through the taper sleeve and the top end is provided with a pressing block. Through the centering of the positioning spigot of the motor and the floating taper sleeve, the vertical tolerance between the joint surface of the motor and the joint surface below is guaranteed; the alignment is made by the thrust cylinder to limit the freedom of rotation of the workpiece; the counterbore of the joint screw of the motor is about the center of the fixture tooling Symmetrical, greatly improving the machining accuracy and efficiency of the workpiece.

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...
