The present invention is a kind of cam-type nut fixing device, by pedestal, cam, sliding shoe, connecting axle, limited block and nut, laying piece forms, cam and limited block lay respectively at the two ends of pedestal, according to being separately installed with connecting axle, sliding shoe and nut by square by cam to the direction of limited block.
During use, nut is placed on to nut and lays on piece, to pressing down, cam is rotated cam depression bar, by the connecting axle promotion sliding shoe contacting with cam, to nut, lay piece and move, nut is fixed between sliding shoe and limited block.
One end of pedestal of the present invention is provided with groove, and the both sides of cam are rotatably connected to cam support bar, and cam support bar is vertically fixed in the groove of pedestal, and cam, when rotating, can remain with groove and be separated, and cam is rotated more efficient.
As preferably, nut lays that piece is laid piece by a hex nut and two arc stop blocks combine; Hex nut is laid the obtuse angle that the vertical section of piece comprises 120 °; In two arc stop blocks comprise camber line arc length all identical with radian.
Nut in the present invention lays that piece is laid piece by a hex nut and two arc stop blocks combine, and hex nut is laid the obtuse angle that the vertical section of piece comprises 120 °; In two arc stop blocks comprise camber line arc length all identical with radian.If nut is round nut, can it be fixed and be laid by two arc stop blocks; If nut is hex nut, can lays piece by a hex nut that comprises 120 ° of obtuse angles and be fixed and lay, the stability when having strengthened nut and being positioned at nut and laying piece.
As preferably, sliding tray is between groove and limited block; And the bottom of sliding shoe is connected with close sliding tray one end near limited block by spring.
Sliding tray in the present invention is between groove and limited block; And the bottom of sliding shoe is connected with close sliding tray one end near limited block by spring.Due to the characteristic of cam and the length of the required displacement of sliding shoe, the present invention is designed to sliding tray between groove and limited block, in the bottom of sliding shoe, by spring, be connected with close sliding tray one end near limited block simultaneously, make after nut is fixed, is machined, only need unclamp cam depression bar, under the effect of spring, cam and sliding shoe can restore automatically, for screw thread next time is fixedly prepared.
As preferably, cam depression bar is L-type, and its one end and cam fix, and the other end is suspended in the top of limited block.
Cam depression bar in the present invention is L-type, and its Design of length is the top to limited block by cam, makes the length long enough of cam depression bar, presses down more laborsaving.
As preferably, the center of limited block is provided with machining hole.
The present invention is provided with machining hole in the center of limited block, makes after nut is fixed, and conveniently its inner surface is processed.
The present invention compares with existing nut fixing device, by coordinating of cam and spring, realizes nut is fixed and is unclamped.Therefore beneficial effect of the present invention is: (1) is fixing more simple efficient to nut; (2) simple in structure, convenient manufacture; (3) production cost is low.
