The top ends of the extension rods of the first cylinder and the second cylinder Both are connected with cylinder pressure claws, and positioning pins are symmetrically connected to both sides of the center of the upper surface of the bottom plate of the jig. The positioning pins are located between the two cylinder pressure claws. Located below the pressure jaws of the cylinder, the upper surface of the jig bottom plate at the rear of the side pressure plate is connected with a product profiling fixing block.

The upper surface of the fixture bottom plate is an inclined plane, the thickness of the front part of the fixture bottom plate is smaller than the thickness of the rear part, a groove is opened in the middle of the fixture bottom plate, and the side of the groove is an inclined plane.

The product profiling fixing block is a right-angled trapezoidal structure, and the hypotenuse of the product profiling fixing block is in contact with the hypotenuse of the product.

The product profiling fixing block and the bottom plate of the jig are positioned by positioning pins and fixedly linked by bolts.

The side pressure plates are all provided with pin holes, and the side pressure plates are all slidably connected with the positioning pins through the pin holes.

A fixed block is installed on the lower right corner of the upper surface of the fixture base plate.

Both the first support arm and the second support arm are fixedly connected to the flange plate through bolts.

Beneficial effects: the utility model adopts the frame structure, which is light in weight, mostly in detachable connection mode, easy to assemble, low in transportation and manufacturing costs, and adopts cylinder pressing claws to clamp the workpiece, which is simple and fast, saves time and reduces the labor intensity of workers At the same time, the workpiece is positioned through the tight fit of the positioning pin hole, the installation error is small, the positioning accuracy is high, and the quality of the workpiece is stable. The fixture is installed on the machine tool through the flange and can rotate 360°, which can accurately and quickly rotate the workpiece To the set angle, process its side and inner groove surface.
