Abstract
The invention relates to the field of a grinding fixture, aiming at providing a workpiece clamping device and a workpiece clamping method for a cylindrical grinding machine. The workpiece clamping device for the cylindrical grinding machine comprises a connecting handle, a headstock center, a one-way bearing, a bearing seat, a workpiece clamping body, an adjusting component, a clamping toggle piece, a toggle piece opening stay rope, a deflector rod position sensor and a controller, wherein the front end of the connecting handle is provided with a center hole; the rear end of the headstock center is arranged in the center hole; an inner ring of the one-way bearing is connected with the connecting handle in a transmission way; the bearing seat is provided with a front check ring and is connected with an outer ring of the one-way bearing; the workpiece clamping body is provided with a middle hole and an opening; the adjusting component is respectively connected with the workpiece clamping body and the front check ring; the clamping toggle piece is provided with a clamping arc surface at the inner end and is articulated with the opening side end; a plurality of clamping adjusting screws which are distributed along the circumference are arranged at the side periphery of the workpiece clamping body; the two ends of the toggle piece opening stay rope are respectively connected with the outer end of the clamping toggle piece and a deflector rod of the cylindrical grinding machine. After the workpiece clamping device for the cylindrical grinding machine is used, the coaxiality between the clamping axis and the workpiece axis can be maintained, clamping is conveniently carried out, and the clamping efficiency is higher.
Description
technical field [0001] The invention relates to the field of grinding fixtures, in particular to a workpiece clamping device and a workpiece clamping method for an outer cylindrical grinder. Background technique [0002] Pneumatic (hydraulic) dynamic chucks are commonly used in cylindrical grinders as the workpiece clamping device to cooperate with the top to clamp the workpiece, which has the disadvantage that the coaxiality between the clamping axis and the workpiece axis is difficult to guarantee; Chinese patent application number: utility model disclosure of CN 201120209154.3 Provided is a universal chuck device for cylindrical grinding machines, comprising a symmetrically arranged first clamping block and a second clamping block, the left and right ends of the first clamping block and the second clamping block are respectively provided with Adjusting bolts and fastening bolts, the first clamping block and the second clamping block are connected by adjusting bolts and fa...
