A workpiece clamping device for a CNC brake camshaft grinder

Abstract

The invention discloses a work-piece clamping device of a numerically-controlled brake camshaft grinding machine. The work-piece clamping device comprises a grinding machine base, a second clamp supporting rod and a first clamp supporting rod are fixedly installed at the left end and the right end of the upper surface of the grinding machine base, clamp heads are arranged on the first clamp supporting rod and the second clamp supporting rod, a work-piece to be machined is movably clamped between the two clamp heads, and electric telescopic rods are fixedly installed inside a cavity of the first clamp supporting rod and a cavity of the second clamp supporting rod. According to the structure of the work-piece clamping device, tension springs are elastically stretched through telescoping regulation of the electric telescopic rods, mutual rotation of first clamping blocks and second clamping blocks is realized through clamping blocks movably arranged on fixing pin shafts in a sleeving mode and limiting rods, and therefore the clamp heads can be controlled to clamp or loosen the work-piece to be machined, rotary machining of an externally-connected motor can be easily realized through cooperation among ball limiting bases, balls and a bearing lantern ring, and the problem that the clamp heads are not flexible is well solved.

Description

technical field [0001] The invention relates to the technical field of grinding machine-related equipment, in particular to a workpiece clamping device for a numerically controlled brake camshaft grinder. Background technique [0002] Camshafts are widely used in gasoline engines or diesel engines to control the switching of fuel injection pumps or the opening and closing of intake and exhaust valves. The quality of the camshaft directly determines the performance of the engine. The camshaft is usually ground by a CNC camshaft grinder. During grinding, the camshaft is clamped in the top and tail tips, and the top drives the workpiece to rotate. The feed movement of the grinding wheel is linked with the rotation of the workpiece to process the For camshafts that meet the requirements, the existing camshaft fixtures are very inflexible, and most of them are limited by manual operation, which is very inconvenient to use. For this reason, we propose a workpiece clamping device f...

The camshaft is usually ground by a CNC camshaft grinder. During grinding, the camshaft is clamped in the top and tail tips, and the top drives the workpiece to rotate. The feed movement of the grinding wheel is linked with the rotation of the workpiece to process the For camshafts that meet the requirements, the existing camshaft fixtures are very inflexible, and most of them are limited by manual operation, which is very inconvenient to use. For this reason, we propose a workpiece clamping device for a CNC brake camshaft grinder to solve the problem. above question
