Powered turret for directly driving cutter head through torque motor

Abstract

The invention relates to a powered turret for directly driving a cutter head through a torque motor, which relates to a turret of a horizontal-type compound turning and milling center. The powered turret comprises a cutter head, a main-shaft motor, a core shaft, a guide pin, an inner tooth disk, an outer tooth disk, a lateral tooth disk, a tooth-disk seat and a cutter-head driving inner sleeve, wherein the cutter-head driving inner sleeve is installed at the outer part of the core shaft, the tooth-disk seat is installed at the front part of the cutter-head driving inner sleeve, the guide pin, the lateral tooth disk, the outer tooth disk and the inner tooth disk are sequentially installed on the tooth-disk seat, the front end of the core shaft is connected with the main-shaft motor through a bolt, and the cutter head is respectively connected with the inner tooth disk and the cutter-head driving inner sleeve through bolts; the powered turret has the structure that a power device and a rotating-angle detecting device are installed at the rear part of the cutter-head driving inner sleeve; a box body is installed at the outer part of the power device; a core-shaft fixed supporting seat is installed at the rear part of the core shaft and is fixed through a locknut, and meanwhile, the core-shaft fixed supporting seat is fixedly arranged on the box body through bolts. The powered turret has the characteristics that the powered turret has the advantages of novel structure, convenience in machining, small size and large torque, the precision is improved, the machining cost is lowered, the maintenance cost is lowered, and the like.

Description

technical field [0001] The power turret of the present invention, which uses a torque motor to directly drive a cutter head, relates to a turret of a horizontal turning and milling compound center. Background technique [0002] The cutterhead rotation form of the traditional turret structure currently used is mainly driven by an ordinary servo motor to rotate the reducer. The traditional turret structure is complex, the installation space required by the components is large, the turret is large in size, and the overall size is too long. If there are too many reducers, there will be an additional transmission link, low transmission accuracy, large transmission clearance, etc., and the cost is high. As for the overall design of the machine tool, because the length of the turret is longer, the stroke of the corresponding Z-direction feed axis is longer in the structural design of the whole machine, so that the corresponding parts connected with it will be lengthened, such as th...
