The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Referring to the auxiliary bracket shown in the accompanying drawing 1,2,3, comprise the bracket body 1 that is positioned at bottommost, be arranged on the elevating mechanism 2 on the bracket body 1 and be installed in guiding mechanism 3 on the elevating mechanism 2.
As shown in the figure, elevating mechanism 2 comprises the lifting screw 4 that is arranged on the bracket body 1, is threaded in the nut 5 on the lifting screw 4, when rotation nut 5, lifting screw 4 along upper and lower to lifting.Guiding mechanism 3 comprises the pedestal 6 that is fixedly mounted on screw tip, is arranged on the grip unit 7 on pedestal 6 upper surfaces, grip unit 7 comprises a pair of universal ball support 8 and 8 ' that can relatively move on pedestal 6, on each universal ball support 8 universal ball 9 is installed, workpiece can be clamped between a pair of universal ball 9 and 9 '.Be installed with second handle 17 on the nut 5.
In order to make a pair of universal ball support 8 and 8 ' to relatively move, line slideway 10 before and after the upper surface of pedestal 6 is provided with, the bottom of universal ball support 8 is equipped with and moves forward and backward slide block 11, and universal ball support 8 is installed on the line slideway 10 of front and back movably by moving slider 11 before and after this.In order to drive conveniently, on the upper surface of pedestal 6, be installed with screw bracket 12, screw bracket 12 is provided with screw rod 13, the axial line of screw rod 13 parallels with the straight line at front and back line slideway 10 places, universal ball support 8 before and after being installed on the line slideway 10 also is threaded on the screw rod 13 simultaneously, when rotating screw bar 13, universal ball support 8 moves forward and backward along front and back line slideway 10.User's operation for convenience is installed with first handle 14 on an end of screw rod 13.
In order to make whole auxiliary bracket to move along left and right directions, on bracket body 1, also be provided with left and right sides line slideway 15, lathe (not marking among the figure) is provided with move left and right slide block (not marking among the figure), the move left and right slide block is installed on the left and right sides line slideway 15, when the move left and right slide block when left and right sides line slideway 15 moves, bracket body 1 moves relative to the lathe left and right directions.Bracket body 1 also is provided with locking member 16, and the bottom of locking member 16 is the bigger elastical cloth of coefficient of friction, and when the bottom of locking member 1 pushed against on lathe, bracket body 1 is relative with lathe to be locked.
The auxiliary bracket of present embodiment is by rotation first handle 14, and universal ball 9 and 9 ' relatively moves, thereby makes that a pair of universal ball 9 and 9 ' can clamping different-diameter workpiece.By rotation second handle 17, make that the grip unit 7 of holding workpiece can oscilaltion under the drive of lifting screw 4.In addition, auxiliary bracket also may move relative to the lathe left and right directions.Therefore, the auxiliary bracket of present embodiment has the translational degree of freedom of 3 orthogonal directions and the rotational freedom of 3 orthogonal directions.When putting into the workpiece of different-diameter rule, can adjust arbitrarily adjusting structure or elevating mechanism, when putting into irregular workpiece, satisfy its needs to greatest extent, as when diameter of work is very big, when adjusting guiding mechanism 3, adjust elevating mechanism 2 again, avoided the interference of workpiece when revolution.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed within the protection domain of the present utility model.
