The technical problem to be solved in the present invention, it is to provide a kind of workpiece positioning clamp, realization is quick, is accurately positioned, and carries
High workpiece processing quality and efficiency.
What the present invention was realized in：A kind of workpiece positioning clamp, including a mainboard, two short axles, two trapezoidal elliptic wheels, two
Gear and one handle；Two short axles are arranged in the mainboard, and it is described trapezoidal ellipse that the both ends of each short axle install one respectively
Circle wheel and a gear, the trapezoidal elliptic wheel drive its rotation by gear, and the two trapezoidal elliptic wheels are located at the same of mainboard
Side, by piece-holder between two trapezoidal elliptic wheels, two gears are located at the opposite side of the mainboard, intermeshing, institute
Handle is stated to be installed on any gear.
Further, the cross section of the trapezoidal elliptic wheel is inverted trapezoidal structure, is advantageous to workpiece firm grip in two
Between trapezoidal elliptic wheel.
Further, the shape size of the two trapezoidal elliptic wheels is consistent, and workpiece centre position is searched available for quick.
Further, the modulus of two gears is consistent with number of teeth difference, drives synchronous backward to rotate by the handle, from
And trapezoidal elliptic wheel synchronous backward is driven to rotate.
Further, each short axle by a bearing hinge joint on the mainboard.
Further, a pad is installed at each short axle both ends respectively, and the shim size is more than the short axle end
Face size, it is ensured that short axle is always positioned between trapezoidal elliptic wheel and gear, will not produce skew.
Further, the pad is secured by bolts in the short shaft end face.
Further, the short axle and the junction of trapezoidal elliptic wheel are fastened by pin key.
Further, the junction of the short axle and gear is fastened by pin key.
Further, a liner plate is provided between the two trapezoidal elliptic wheels, reduces the abrasion of workpiece and mainboard.
The invention has the advantages that：Rotated by the trapezoidal elliptic wheel synchronization opposite direction of two same sizes, can be by workpiece
It is clamped between two trapezoidal elliptic wheels, realizes fast positioning, the adjust automatically location of workpiece, it is ensured that the center of various sizes of workpiece
Position is still fallen between the two trapezoidal elliptic wheels, is facilitated main shaft precisely to be punched, is greatly improved work pieces process efficiency, carry
High yield quality.

Embodiment
Refer to Fig. 1 and Fig. 2, a kind of workpiece positioning clamp of the present invention, including a mainboard 1, two short axles 2, two trapezoidal ellipses
Take turns 3, two gears 4 and one handle 5；Two short axles 2 are arranged in the mainboard 1, and the both ends of each short axle 2 install one respectively
3 and one gear 4 of trapezoidal elliptic wheel, the trapezoidal elliptic wheel 3 drive its rotation, the two trapezoidal ellipses by gear 4
Wheel 3 is located at the same side of mainboard 1, and between workpiece 200 is held on into two trapezoidal elliptic wheels 3, two gears 4 are located at the mainboard
1 opposite side, intermeshing, the handle 5 are installed on any gear 4.
Preferably, the cross section of the trapezoidal elliptic wheel 3 is inverted trapezoidal structure, be advantageous to by the firm grip of workpiece 200 in
Between two trapezoidal elliptic wheels 3.
Preferably, the shape size of the two trapezoidal elliptic wheels 3 is consistent, workpiece centre position is searched available for quick.
Preferably, the modulus of two gears 4 is consistent with number of teeth difference, synchronous backward is driven to rotate by the handle 5, from
And the trapezoidal synchronous backward of elliptic wheel 3 is driven to rotate.
Preferably, each short axle 2 is articulated on the mainboard 1 by a bearing 6；
Preferably, a pad 7 is installed at each both ends of the short axle 2 respectively, the size of pad 7 is more than the short axle end
Face size, it is ensured that short axle 2 is always positioned between trapezoidal elliptic wheel 3 and gear 4, will not produce skew；The pad 7 passes through bolt
8 are fixed on the short shaft end face.
Preferably, the short axle 2 and the junction of trapezoidal elliptic wheel 3 are fastened by pin key 9；The short axle 2 and gear 4
Junction is fastened by pin key 9.
Preferably, being provided with a liner plate 10 between the two trapezoidal elliptic wheels 3, effectively workpiece is protected not ground with mainboard 1
