Abstract
The utility model relates to a numerical-control rotary table, belonging to the technical field of the design and manufacture of the numerical-control rotary table. The outer side of a table body is provided with a direct current servo motor, and a matched gear is provided with a worm. The lower part of a worm gear is provided with an inner clamping tile, and the outer part of the inner clamping tile is provided with an outer clamping tile. Six hydraulic oil cylinders are arranged in a table base, and the inner part of the table base is provided with a circle grating. The numerical-control rotary table has the working principle: when the table needs to be started, the clamping tiles are opened by steel balls to clamp the worm gear, and the direct current servo motor drives the table to rotate by the worm gear. When the table needs to be rotated, chamber oil on the hydraulic oil cylinders flows back to an oil return tank, the clamping tiles loosen the worm gear, and the table and the worm gear are driven by the servo motor together to do rotary motion according to control instructions. As the circle grating can be controlled in reading, the rotary table can do the rotary motion or indexing motion of any angle, and the table can be accurately stopped at the zero position. The numerical-control rotary table has the advantages of simple structure and reasonable design and solves the problems of the existing product.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of NC rotary table.
Background technology
The rotary table that uses on Digit Control Machine Tool at present mainly is a mouse fluted disc workbench, and the accuracy of manufacture of this mouse fluted disc workbench requires high especially.Production cost is big.In addition, owing to structural reason, feasible rotary inertia, elastic deformation, the backlass that is in operation and produces, problems such as action hysteresis.Do not guarantee the running accuracy and the stationarity of panoramic table, thereby influence the crudy of part.Therefore say present mouse fluted disc workbench in design with use all undesirable.
Summary of the invention
At above-mentioned situation, the purpose of this utility model provide a kind of can arbitrarily angled calibration and the higher NC rotary table of indexing accuracy.To solve the problem that existing product exists.
Structure of the present utility model is as shown in drawings: the outside at the work stage body has DC servo motor.Reduction gearing is housed on motor output shaft.In the reduction gearing bottom one associated gear is arranged.One worm screw is arranged on associated gear.The supporting worm gear of worm screw.Duplex needle bearing is equipped with at two ends worm screw.The right-hand member dress thrust bearing of worm screw.Needle bearing is used for radial support, and thrust bearing is used for bearing axial force.In the bottom of worm gear clamping shoe in is arranged.In the outside of interior clamping shoe clamping shoe outside is arranged.In the workbench bottom one table base is arranged.Have 6 hydraulic jacks in the table base.Have piston in the oil cylinder.Lower part of piston has a steel ball.One spring is arranged at the bottom of steel ball.Edge steel roller guide rail is housed on table base.Central part at workbench has a workbench rotating shaft.One biserial radial short cylindrical roller bearing is arranged on the rotating shaft.In this bearing bottom one taper roll bearing is arranged.One circle grating is arranged in table base inside.Operation principle of the present utility model is: when workbench need start, hydraulic system started, and the oil cylinder epicoele enters pressure oil, and descent of piston struts clamping shoe by steel ball.Worm gear is clamped.DC servo motor drives worm gear.The worm gear drives workbench rotates.This moment, hydraulic system quit work.When workbench need turn round, control system was sent instruction, made hydraulic jack epicoele oil flow back to fuel tank.Under the effect of spring restoring force, lift steel ball.Clamping shoe unclamps worm gear.Workbench and worm gear are done gyration by control instruction together under servomotor drives.At this moment, because of rotary table is provided with zero point, workbench returns zero control, by table stop collision limit switch, makes the work table rotation action by becoming at a slow speed fast.Because the measuring cell of rotary table circle grating can carry out reading control, guaranteed that rotary table can do revolution or calibration at any angle.Make workbench zero dead stop exactly.
The utility model is simple in structure, and is reasonable in design, owing to have rotational angle measuring cell circle grating, makes rotary table can do accurately revolution or calibration at any angle.The problems such as rotary inertia, elastic deformation, backlass, motion delay, friction, vibration and wearing and tearing of the intermediate link generation of old-fashioned mouse fluted disc workbench existence have been solved.Thereby the running accuracy and the stationarity of panoramic table have been improved.
