Abstract
The invention relates to a new type dividing head, comprising a box, a main shaft, a gear, a driving rack, a driven rack and a transition rack, wherein the main shaft, the gear, the driving rack, the driven rack and the transition rack are arranged in the box; the gear and the main shaft are fixedly connected; the driving rack is meshed with one side of the gear, and the driven rack is meshed with the other side of the gear; the transition gear is positioned at the bottom of the gear; the driving rack is meshed with one side of the transition rack, and the driven rack is meshed with the other side of the transition rack. By adopting the new type dividing head, the influence on dividing by the intertooth space between the gear and the racks is eliminated, and the dividing accuracy is high; a form of gear and rack meshing is adopted, the racks are moved for a distance, and the gear is rotated for a corresponding angle, and the dividing efficiency is high.
Description
Technical field
The present invention relates to a kind of new index head.
Background technology
Dividing head is a kind of servicing unit being widely used in the Metal Cutting Machine Tools such as milling machine, drilling machine and grinding machine, for holding workpiece and make workpiece revolution and calibration.Traditional dividing head is mainly comprised of parts such as base, main spindle box, calibration disc, dividing arm and main shafts, workpiece is fixed on chuck, utilize worm-and-wheel gear transmission, this worm-and-wheel gear is connected with main shaft, finally by rotating dividing arm, carries out calibration.In traditional dividing head, in worm-and-wheel gear transmission, there is inter-lobe clearance, cause the precision of calibration not high, and worm screw rotate a few, worm gear just turns an angle, and calibration efficiency is low.
Summary of the invention
Technical problem to be solved by this invention is to provide the new index head that a kind of calibration efficiency is high, precision is accurate.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of new index head, comprise casing, main shaft, gear, active tooth bar, driven tooth bar and transition gear, described main shaft, gear, active tooth bar, driven tooth bar and transition gear are all positioned at described casing, described gear is fixedly connected with described main shaft, described active tooth bar is meshed with a side of described gear, described driven tooth bar is meshed with the opposite side of described gear, described transition gear is positioned at the bottom of described gear, and described active tooth bar is meshed with a side of described transition gear, described driven tooth bar is meshed with the opposite side of described transition gear.
The invention has the beneficial effects as follows:
The present invention has eliminated the impact on calibration of inter-lobe clearance between wheel and rack, and indexing accuracy is high; The form that adopts rack and pinion engagement, tooth bar moves a certain distance, and gear rotates corresponding angle, and calibration efficiency is high.Between tooth bar, be provided with transition gear, initiatively rack drives transition gear rotates, and transition gear drives driven tooth bar to move, and realizes the interlock of active tooth bar and driven tooth bar, saves the energy.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described new index head also comprises drive unit, and described drive unit is positioned at the outside of described casing, and is connected with one end of described active tooth bar.
Further, described drive unit is pneumatic cylinder or hydraulic cylinder.
Further, described new index head also comprises motor, and described motor is connected with described drive unit.
Adopt the beneficial effect of above-mentioned further scheme to be, by drive unit and motor, drive initiatively tooth bar to move, can complete fast calibration, save trouble and labor.
Further, described new index head also comprises standard and mandrel, and described standard is arranged on the bottom of described casing by described mandrel.
Adopt the beneficial effect of above-mentioned further scheme to be, solved the collimation technique problem of new index head, can be good in actual use accomplishing to make the new index head of application in slave mode.
