As a further improvement of the utility model, the two sides of the bottom plate are provided with handles. The handle is convenient for workers to carry.
As a further improvement, the bolt seat is provided with a bolt hole and a mounting hole. The top inserted pin or the side inserted pin can penetrate into the inserted pin hole to be placed; the bolt seat can be fixed on the bottom plate by a mode that bolts penetrate through the mounting holes.
As the utility model discloses further improve, the side bolster be equipped with the connecting hole and dodge the hole, the fixing base be equipped with the screw hole that corresponds with the connecting hole. After the bolt penetrates through the connecting hole and the threaded hole, the side cushion block is fixed; the avoiding hole is used for avoiding the collision of the side positioning shaft and the side cushion block when the side inserting pin is inserted into the side positioning hole, so that the positioning of the side positioning shaft on the workpiece is influenced.
The fast clamp is designed based on the principle of double-rocker mechanism in planar four-bar mechanism and has the basic structure comprising connecting rod, frame, two connecting rods, etc. When the two hinge points of the connecting rod and the hinge point of one of the connecting rod and the rack are on the same straight line, the mechanism is in a dead point position, and at the moment, the pressed workpiece cannot enable the pressure head to be loosened no matter how large the counter force is, so that the clamping principle of the quick clamp is realized. The quick clamp commonly used in the industry is adopted by the left quick clamp and the right quick clamp.
The utility model has the advantages of simple, convenient and quick detection; firstly, a workpiece is placed on a fixed seat, a top bolt is used for positioning a top hole of the workpiece, a side bolt is used for positioning a side hole of the workpiece, a right quick clamp is used for pressing a top plate part of the workpiece, and a left quick clamp is used for pressing a side plate part of the workpiece; circle logical no-go gage one end is for leading to the rule, and the other end is the no-go gage, and the circle leads to the no-go gage and is used for detecting a side board portion of work piece, and square logical no-go gage subassembly is used for detecting top plate portion and another side board portion of work piece.
