Abstract

The invention discloses a cylindrical grinding workpiece clamping device. The cylindrical grinding workpiece clamping device is fixed to a working main shaft of a cylindrical grinder and comprises a chuck main body part, a clamping part, a tip and a transmission mechanism, wherein the chuck main body part has an accommodating part and is driven by a working spindle to rotate; the clamping part is connected with the chuck main body part and is provided with at least two clamping jaws which can be far away from / close to the axis of the chuck main body part; the tip comprises a tip main body part partially accommodated in the accommodating part and a tip part extending from the interior of the accommodating part to one side of the clamping part, and the tip can rotate relative to the chuck main body part; and the transmission mechanism is connected with the clamping part and is used for enabling the clamping jaws to move along the axis of the chuck main body part by increasing / decreasing a radial distance, the clamping part is controlled and driven to automatically clamp and loosen the workpiece through a pneumatic mode, and the machining efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of grinding machine clamps, in particular to a cylindrical grinding workpiece clamping device. Background technique [0002] Cylindrical grinder (abbreviated as cylindrical grinder) is a kind of mechanical equipment that can process the outer surface of the workpiece or the end face of the shaft shoulder. Before the workpiece is processed, it needs to be clamped and positioned by a special fixture. At present, the most used grinding machine fixture is the heart-shaped fixture. For example, the patent with the authorized announcement number CN203579405U discloses a "grinding machine chuck", which belongs to the common heart-shaped fixture. The structure includes a collet ring, two clamping bolts arranged at intervals and a clamping handle. When this kind of collet clamps the workpiece, the workpiece is placed in the collet ring and the preliminary positioning of the workpiece is realized by adjusti...
