When some digital products of production, some parts of logarithmic code product are often needed to carry out assembling and fastening, carrying out assembling in fastening process, usually be all that some large components are placed on the workbench of bottom, such as by the shell of larger digital product, put the top being clamped in the workbench being provided with special fixture to fix, generally for the efficiency of increase work, adopt the fixture with negative pressure suction nozzle often, then by parts less for other, metallic plate such as shielding, the primary structural component of screen etc., put on digital product shell on the table one by one, at the screw fixed position place of these less parts, be provided with the screw hole through screw, the below of screw hole is provided with corresponding screwed hole, the automatic screw being used for tightening screw at present specially follows closely cutter, be contained in top can two horizontal direction X-axis, on the XY number of axle word sliding frame controlled by digital module of Y-axis motion, what this screw cutter tips was typically provided with the cross coordinated with the cross recess of screw revolves ailhead, this below of revolving ailhead is provided with the screw automatic supply device for automatically providing screw, the below of this screw automatic supply device, be generally a circular sleeve, when revolving ailhead rising at every turn, screw in the below of screw automatic supply device by the side opening offered from sleeve dispose into, the center of side is with when tightening screw aligns under a bushing, revolve the screw hole on ailhead and same of sleeve decline light pressure primary structural component, revolve ailhead continue to move downward and rotate, screw will be tightened, but in the process used, because the head of screw is larger, the diameter of sleeve is identical with the diameter of the head of screw, therefore after screw is presented to sleeve, drop from sleeve to prevent screw, arrange magnet not decline to adsorb screw in the bottom of sleeve at present, cause axis in screw stops in sleeve can deflect, the cross cutter head revolving ailhead is caused to be not easy to align with screw cross recess, that easily causes screw revolves askew phenomenon, therefore a kind of structure of redesign is needed, both screw can have been kept not deviate from from sleeve, can ensure again can guarantee that revolving ailhead aligns mutually with the cross recessed center on head of screw top when revolving ailhead and declining simultaneously, thus enable to revolve ailhead and screw coordinates exactly, improve the ride comfort of production process, and qualification rate when producing in batches and quality can be guaranteed.
Utility model content
The utility model is to solve above-mentioned technical problem, provides a kind of screw positioning head automatically screwing screw device that can not need to take separately screw.
The utility model adopts following technical scheme: this screw positioning retaining cap automatically screwing screw device is located at the screw sleeve lower end that automatically screws screw device and is fixedly connected with use, include columnar positioning head body and positioner, this positioning head body and the first end that screw sleeve matches are provided with the diameter sleeve hole identical with screw sleeve overall diameter, this positioning head body second end is provided with and the screw hole that communicate coaxial with this screw sleeve, this screw hole interior diameter is identical with the diameter of bore of screw sleeve, described positioner is located at the screw hole side on positioning head body, the sleeve hole of this positioning head body is mutually permanently connected in the lower end of screw sleeve and screw sleeve, the screw hole place that described positioner is included in positioning head body around screw hole axis radial evenly arrange several run through the isodiametric through hole of circle of screw hole walls, with isodiametric spherosome and watt ring set be set in outside spherosome of these several through hole corresponding matching, described spherosome is located in through hole respectively outside screw hole, described watt of ring set cuff the sleeve hole of this positioning head body outside and with described spherosome resilient engagement, penetrated the inner side of described screw hole hole wall by through hole inside described spherosome, the diameter of a circle that the inner inner side sphere of several spherosomes described is formed is greater than the overall diameter of screw thread bar, be less than the overall diameter of the screw head of screw simultaneously.
Automatically screw in the screw positioning head of screw device of the present utility model, the lower end of described screw sleeve is provided with external screw thread, is provided with the internal thread coordinated with it and is connected with screw bush whorl in the screw sleeve hole of described positioning head body.
Useful effect: adopt above-mentioned technical scheme, automatically the screw positioning head screwing screw device of the present utility model in use, be fixed on the lowest end of the screw sleeve automatically screwing screw device, in time having screw to enter in screw sleeve, screw falls downwards under gravity, then the threaded shank portion of screw coordinates with the inner edge of spherosome, screw head divides interference, when revolving ailhead and moving downward and screw fit, do not affect the whereabouts of screw, and there is the good effect screwed.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1, be structure sectional view when screw of the present utility model and screw positioning head are interfered static;
Fig. 2, for screw of the present utility model is by structure sectional view during screw positioning head.
