The worm gear is sheathed on the gear shaft, the worm gear is fixed to a flange plate, a plurality of grooves divided equally are arranged in the periphery of the flange plate, the gear shaft is fixed with a steel balls base in the circumferential direction, the steel balls base is provided with a plurality of steel balls holes which are uniformly distributed, steel balls whose diameters are bigger than the hole wall are arranged in the steel balls holes, the part with steel balls holes on the steel balls base is positioned in the part with slots in the periphery of the flange plate, a gap is provided between the inner circle in the part of the steel balls base and the external diameter of the gear shaft, the gear shaft is fixed in the circumferential direction with a splined shaft which can slide in the axial direction through the control of an operating handle, and the front part of the splined shaft is a stepped circular ring structure which is inserted into the gap between the steel balls base and the gear shaft. A handle seat is sheathed on the splined shaft, the splined shaft and the handle seat are fixed in the circumferential direction and connected in sliding mode in the axial direction, and the operating handle is fixed on the handle seat by a straight pin. The utility model uses the steel balls as the engaging components with no need to manufacture end gear sleeves, the whole device is easy to manufacture, and the production cost is reduced.
Description
Technical field:
The utility model relates to a kind of automatic feeder of radial drilling machine.
Background technology:
General automatic feeder is realized autofeed by the engagement of two end tooth covers.When two end tooth cover engagements, power is passed to worm gear by worm screw, drives the rotation of two end tooth covers, and gear shaft is rotated thereupon, has realized autofeed.When end tooth cover separates, the idle running of an end tooth cover, another end tooth cover does not rotate, and can not make the gear shaft rotation, also just can not autofeed.Though this structure can realize autofeed, the end tooth cover processing difficulty of getting up is bigger, and cost is increased.
Summary of the invention:
The purpose of this utility model provides a kind of radial drilling machine automatic feeder, is convenient to processing, reduces production costs.
The purpose of this utility model realizes as follows: this radial drilling machine automatic feeder relates to the gear shaft of power input worm gear and power output, worm gear is inserted on gear shaft, its main feature is the power-off device between worm gear and the gear shaft, specifically: be fixed with a ring flange on the worm gear, the groove that has several to divide equally on the ring flange inner periphery, circumferential stationary balls seat on gear shaft, steel ball seat has uniform some steel ball holes, the steel ball of diameter greater than pore wall thickness is housed in the steel ball hole, the quantity of the groove on the ring flange is the integral multiple of steel ball hole quantity on the steel ball seat, what have steel ball hole on the steel ball seat that part ofly is in the ring flange inner periphery and has in the part of groove, and it is gapped between the interior circle of this part of steel ball seat and the gear shaft external diameter, the circumferentially fixing splined shaft that can slide vertically by control crank control on gear shaft, the front end of splined shaft is to be inserted into the stepped endless belt in the gap between steel ball seat and the gear shaft.
Be with handle set on the splined shaft, also be slidingly connected vertically by transformation of the way key is circumferentially fixing between splined shaft and the handle set, control crank is fixed on the handle set by straight pin, and handle set is connected on the terminal pad by bearing, and terminal pad is fixed on the gear-box.
When control crank is pulled binding site, the part that the stepped endless belt of splined shaft is thicker enters into steel ball seat inside, steel ball is all entered in the ring flange groove, power makes worm gear, ring flange rotation, drive the steel ball seat rotation by steel ball again, thus the rotation of driven gear axle, and gear shaft drives the splined shaft rotation again, drive the handle set rotation by the transformation of the way key on the splined shaft, to realize autofeed.
When control crank is pulled disengaging configuration, the stepped endless belt of splined shaft breaks away from the steel ball position of steel ball seat than thickness portion, the part that the stepped endless belt of splined shaft is thin has that part of interior round-formed gap of steel ball hole with steel ball seat, the disengaging ring flange contracts in the steel ball, steel ball can not drive the steel ball seat rotation, gear shaft does not rotate, so autofeed stops.
This radial drilling machine automatic feeder needn't be processed the end tooth cover, and adopts steel ball as meshing part, and whole device is convenient to processing, has reduced production cost.
Description of drawings:
Accompanying drawing is the structural representation of the utility model radial drilling machine automatic feeder.
