Abstract
The utility model relates to a headstock structure, which comprises a headstock (1), a polywedge belt pulley, a chuck (3), a fast clamping device (4), heat radiating fins (5), an inner insulating sleeve (6), an outer insulating sleeve (7) and a spindle speed measuring device (8), the outer insulating sleeve (7) is fixed in the headstock (1), the heat radiating fins (5) are mounted at the external surface of the headstock (1), the inner insulating sleeve (6) is mounted in an inner cavity of the outer insulating sleeve (7), a spindle is mounted in an inner cavity of the inner insulating sleeve (6), and the fast clamping device (4) and the chuck (3) are respectively fixed at left and right two ends of the spindle. The utility model can effectively protect the bearings under the condition that the spindle operates with high speed, the bearings adopt the QBC tetrad matching structures with high precision. Two bearings at the front end are in the same one direction, thereby improving the rigidity of the whole spindle. The utility model is specially applicable to the machining of a tailstock and heavy cutting. A heat radiating device of the headstock can effectively prevent the heat expansions of the bearings.
Description
Technical field
The utility model belongs to field of machine tool fittings, particularly relates to a kind of headstock structure.
Background technology
Numerically controlled lathe is very wide in China's scope of application, is that each machining factory owner wants one of equipment, but when the lathe high speed rotating, is easy to generate noise problem, has increased vibration and has produced bigger heat simultaneously, thereby reduced machining accuracy.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of headstock structure
The technical scheme that its technical problem that solves the utility model adopts is: a kind of headstock structure is provided, comprise headstock, polywedge bet wheel, chuck, fast fixture, fin, inner spacing collar, outer separator and main shaft speed measuring device, be fixed with outer separator in the described headstock, the outer separator outer surface is equipped with fin, and the outer separator inner chamber is mounted with inner spacing collar, and main shaft is installed the inner spacing collar inner chamber and two ends, the main shaft left and right sides are mounted with fast fixture and chuck respectively.
Described main shaft speed measuring device is installed on the main shaft top of fin left end inner chamber, and the polywedge bet wheel is installed on the main shaft of main shaft speed measuring device below.
Beneficial effect
The utility model can effectively be protected bearing what main shaft ran up, bearing QBC tetrad distribution structure, precision height.Two bearings of front end are same direction, have improved the rigidity of whole main shaft.Be specially adapted to the processing of tailstock, heavy cut.The heat abstractor of headstock can effectively be protected the thermal expansion of bearing.
