In through-hole；Horizontal anomalous movement is provided with two screw rods in the pedestal, and internal thread and external thread of screw phase are provided in the pedestal
The blind hole of adaptation, the outer diameter of two screw rods, screw pitch equal-specification parameter is consistent but direction of rotation is on the contrary, two screw rod activities intert
It is connect in through-hole and with screw rod worm and gear, two screw rods are connect respectively with the bearing block on the positioning plate of pedestal side, rotation
Keyway positioning pin can drive screw rod to be synchronized with the movement, to ensure that keyway positioning pin is in the centre bit of both sides positioning plate line always
It puts；The mounting hole for installing dial gauge is provided on the positioning plate.
Further, the positioning plate side is provided with lead, and pilot hole, the lead are provided in the pedestal
Activity is interspersed in pilot hole.
Further, the lead end is provided with limiting plate, is provided on the pilot hole inner wall and limiting plate phase
The only side of adaptation.
Further, it is provided with graduation mark on the lead.
The beneficial effects of the utility model：It is simple in structure, it is at low cost, it, being capable of accurate Parts Measurement convenient for promoting
Keyway symmetry.
1st, keyway positioning pin is threadedly coupled with that on pedestal, can be replaced according to demand.
2nd, graduation mark is provided on lead, whether the positioning plate displacement distance available for confirming both sides is consistent, to ensure
Keyway positioning pin is in the center of both sides positioning plate line always.
