Abstract
The utility model provides a positioning center frame of four wheels, comprising a base seat, a left moving vertical plate, a right moving vertical plate, four roller wheels, a screw rod transmissionmechanism and two fastening screws, wherein the screw rod transmission mechanism consists of a bracket, a screw rod, a pilot wheel and two nuts; the center of the four roller wheels is consistent withthe center of a lathe. The center frame has self-positioning function, and can quickly clamp and loosen work pieces and conveniently assemble and disassemble work pieces.
Description
Technical field
The utility model relates to a kind of equipment machining tool, relates in particular to a kind of four-wheel centre of location frame.
Background technology
The centre frame that generally uses on the lathe is the centre frame of three-point fix now, and the adjustment of each fulcrum is regulated respectively.There is the inconvenient problem of regulating.Operating technology to the employee is had relatively high expectations.
The utility model content
The purpose of this utility model exactly in order to address the above problem, provides a kind of four-wheel centre of location frame that adopts the four-wheel location.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of four-wheel centre of location frame, and be installed in and be used for clamping work pieces on the lathe, it comprises:
Base is provided with the chute that stretches about in it;
Move left riser and the riser that moves right, the left and right sides that is installed in riser respectively also can be along the chute move left and right;
Four rolling, symmetry are installed in the relative both sides of move left and right riser, and the center that four rolling forms is consistent with the center of lathe;
Lead screw transmission mechanism comprises support, screw mandrel, handwheel and two nuts, and support is fixed on the right-hand member of base, and two nuts are separately fixed at the side of move left and right riser, and screw mandrel passes two nuts and support is movably connected, and handwheel is connected the left end of screw mandrel;
Two lock-screws are installed in respectively on the base and can form locking to the move left and right riser.
Left and right sides two parts of described screw mandrel adopt the identical positive and negative silk structure of pitch respectively; In described two nuts, be installed in the left-handed nut that is that moves left on the riser, be installed in the right-handed nut that is on the riser that moves right.
Described four rolling is the identical bearing of size.
Compared with prior art, four-wheel centre of location frame of the present utility model has the following advantages:
1, because the center of formed center of four rolling and lathe is consistent, make centre frame have self-locating function.
2, can rapidly clamp and release workpiece by handwheel.
3, the utility model four-wheel centre of location frame is Open architecture, workpiece loading and unloading easily.
Description of drawings
Fig. 1 is the structural representation of facing of the utility model four-wheel centre of location frame;
Fig. 2 is the side-looking structural representation of the utility model four-wheel centre of location frame.
The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model four-wheel centre of location frame, comprise base 1, move left riser 2, the riser 3 that moves right, four rolling 4, by support 5, screw mandrel 6, handwheel 7 and two lead screw transmission mechanism and two lock-screws 9 that nut 8 is formed.
In base 1, be provided with the chute 11 that stretches about.
Move left riser 2 and the riser 3 that moves right be installed in respectively riser the left and right sides and can be along chute 11 move left and right.
Four rolling 4 symmetries are installed in the relative both sides that move left the riser 2 and the riser 3 that moves right, and the center that four rolling forms is consistent with the center of lathe.Four rolling in the utility model adopts the identical bearing of size.
Support 5 is fixed on the right-hand member of base 1.
Two nuts 8 are separately fixed at the side that moves left the riser 2 and the riser 3 that moves right, be installed in the left-handed nut that is that moves left on the riser 2, be installed in the right-handed nut that is on the riser 3 that moves right, when shaking handwheel, two nuts 8 are done counter motion along screw mandrel, drive two mobile risers respectively and open or close up.
Screw mandrel 6 passes two nuts 8 and is movably connected with support 5, and left and right sides two parts of screw mandrel adopt the identical positive and negative silk structure of pitch respectively.
Two lock-screws 9 are installed in respectively on the base 1, are used for after the move left and right riser moves into place, with move left and right riser position and lock.
The utility model four-wheel centre of location frame is installed in and is used for clamping work pieces on the lathe, and using method can be as follows in conjunction with Fig. 1:
1, unclamping lock-screw 9 makes two to move riser 2,3 and can move.
2, the left-handed handwheel 7 that shakes makes two to move riser 2,3 respectively to two side shiftings, thereby opens four rolling 4.
3, the workpiece of packing into, for example version roller a.
4, handwheel 7 is shaken in dextrorotation, makes two to move riser 2,3 and move to the centre respectively, thereby draw four rolling 4 in workpiece a is clamped.
5, tighten two lock-screws 9, make two to move riser 2,3 location and can not move.
6, beginning processing work.
