Description
Affiliated technical field
The utility model provides a kind of three positioning chucks, belongs to the Machining Technology field.
Background technology
In at present existing process technology, generally three-jaw or the chuck that workpiece is clamped all is directly to be fixedly mounted on the workbench of lathe spindle or equipment such as milling machine and machining center by bolt, adjustment to the location of workpiece all is to realize by the mode that increases and decreases pad or knock, adjust the problems such as there is low precision in the method for the location of workpiece on the chuck, and efficient is low that are fixed on by these.
The utility model content
The utility model purpose provides and a kind ofly can overcome three high positioning chucks of above-mentioned defective, precision height, efficient.Its technical scheme is:
Comprise chuck seat and the scroll chuck that is fixed on the chuck seat, it is characterized in that: set up the master body, holder and a plurality of tight fixed bolt, and master body inside is evenly equipped with the identical slip screw lifting positioner of three covers, every cover mechanism includes and tightens bolt, be installed in the wheel of pulling of master body sidewall, screw rod, the nut tap gear, lower flange and compress end cap, wherein fixedly connected with chuck seat in the top of holder, its lower end is connected through pin key with the upper end of screw rod, screw flight vertically is installed in the nut tap gear, the upper end of nut tap gear is in bearing is installed in the master body, its lower end is in bearing is installed in lower flange, lower flange is fixed in the master body and is positioned at the lower end of nut tap gear, compressing the end cap screw thread is installed in the lower flange, its top and bearing are conflicted, the external tooth of nut tap gear with pull wheel engagement, tighten bolt and be installed on the master body, its lower end with pull the wheel end face and conflict, uniform and the screw thread of a plurality of tight fixed bolts is through chuck seat, and its lower end contacts with master dignity.
Described three positioning chucks, the tight fixed bolt lower end contacts with master body spherical surface.
Described three positioning chucks, the nut tap gear is connected by inside and outside trapezoidal thread with screw rod.
Its operation principle is: under the arbitrary motionless in advance situation of master body three cover slip screw lifting positioners, by transferring the wheel of pulling in the other two cover lifting positioners, lifting screw is to reach being installed in the adjustment of its position of workpiece on the scroll chuck under the effect of nut tap gear, screw then and tighten bolt and tight fixed bolt, so that the location of workpiece on the scroll chuck spatially is fixed, so far reach the purpose of positioning.
The utility model has compared with prior art increased by three cover slip screw lifting positioners, has effectively improved the aligning precision and the speed of workpiece, excellent working performance.
