Abstract

The invention discloses a novel workpiece clamping device which mainly comprises a spindle, an upper grinding wheel, a fixing ring and a plurality of workpiece clamping wheels, wherein a clamping groove for clamping a workpiece is formed in the middle of each workpiece clamping wheel; the lower grinding wheel is arranged in the fixing ring and is coaxial with the fixing ring; the upper grinding wheel is arranged over the fixing ring and is opposite to the lower grinding wheel; the lower grinding wheel is meshed with the workpiece clamping wheels; the axle centers of the workpiece clamping wheels are uniformly distributed along a circumference; the workpiece clamping wheels are meshed with the lower grinding wheel and the fixing ring at the same time. The novel workpiece clamping device can clamp a plurality of workpieces at the same time, meanwhile can enable the workpieces to be processed to do planetary motion around a grinding head, and is mainly used for workpiece clamping on a parallel surface grinding machine. The novel workpiece clamping device can improve the stress uniformity of a grinding tool, so that the tool is uniformly abraded during workpiece processing, the service life of the tool is prolonged and the use cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of workpiece clamping devices, and in particular relates to a novel workpiece clamping device for clamping parts to be processed. Background technique [0002] Grinding machines are mainly used in the processing of auto parts, bearings, hydraulic parts and other high-precision technical fields that require double-plane grinding, and are widely used in industry. The double-end surface grinder can process the two end surfaces of the workpiece to be processed at the same time. In order to clamp the workpiece to be processed, the clamping device needs to use a disc fixture. In the prior art, the traditional disc fixture used for double-end grinding machines can only realize single-station processing, the use area of ​​the grinding head cannot be effectively utilized, and the workpiece itself cannot move independently, and grinding texture may be generated during processing, which affects Processing accuracy an...
