Description

Technical Field

[0001] The utility model relates to the technical field of chuck detection, in particular to a chuck micro-motion detection device for a numerically controlled lathe. Background Art

[0002] The chuck is a mechanical device used to clamp the workpiece on the CNC machine tool. At present, in order to improve the processing efficiency of the workpiece, the indexing chuck is generally used. The indexing chuck is mainly composed of a hydraulic station, an oil distributor, a rear flange, a connecting rod, a front flange, an indexing chuck, a stuck alarm, a hose, etc.

[0003] The working principle of the indexing chuck is composed of two parts: indexing and clamping. The indexing part realizes the indexing function of the chuck, and the clamping part realizes the clamping function of the chuck. The indexing of the chuck is realized when the product is clamped. The indexing of the chuck is realized by two ejector rods (45-degree ejector rod and 90-degree ejector rod) driving the rotating shaft to rotate to realize indexing. The 45-degree ejector rod pushes the chuck forward to the 45-degree position, and the 90-degree ejector rod pushes the chuck forward to the 90-degree position. The positions of the two ejector rods are interlocked, so as to replace the original lathe chuck, realize one-time clamping of the polyhedron, realize automatic indexing, and perform multi-faceted transposition and multi-process turning processing on the workpiece.

[0004] Before the indexing chuck is installed on a CNC lathe, it is often necessary to inspect it and make it qualified before it can be installed. Most of the existing inspection tables fix the indexing chuck on the inspection seat with bolts, but this method requires repeated removal of the bolts, which is cumbersome and leads to low processing efficiency.
