When the piston rod of the hydraulic cylinder stretches, the pressure rod can drive the arm rod to rotate to realize the lateral movement of the claw rod.

The piston rod of the hydraulic cylinder is provided with a vertical rod, one end of the vertical rod is connected with the piston rod of the hydraulic cylinder, and the other end of the vertical rod is hinged with the other end of the pressure rod.

The arm is hinged to the pressing head assembly through a rotating shaft, the rotating shaft is rotationally coupled to the pressing head assembly, one end of the rotating shaft is fixedly coupled to the arm, and the other end of the rotating shaft is fixedly coupled to the pressing bar.

One end of the claw rod is crescent-shaped, which can facilitate the clamping of the workpiece to achieve centering.

Compared with the prior art, the utility model has the beneficial effects that:

There are centering arms on both sides of the pressure head assembly. When the piston rod of the hydraulic cylinder stretches (vertically moves), it can push the pressure rod hinged with it to move, and the pressure rod drives the arm rod connected to it to rotate and make the claw rod horizontal. One end of the claw rod is crescent-shaped, which can clamp the cylindrical workpiece, so as to realize the centering. The vertical movement of the hydraulic cylinder is converted into the lateral movement of the claw rod through the arm rod, the pressing rod and the connecting rod. This device can avoid the deviation of the workpiece pressing, resulting in the generation of waste products.

detailed description

The technical solutions in the embodiments of the utility model are clearly and completely described below, obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figures 1-2, a seat ring centering device includes a pressure head assembly 1 and a hydraulic cylinder 2. The pressure head assembly 1 is provided with a pressure head 11, and the pressure head assembly 1 is connected to a press. The press can Drive the pressure head assembly 1 and the parts on the pressure head assembly 1 to move up and down. The hydraulic cylinder 2 is vertically arranged on the pressure head assembly 1, and the piston rod of the hydraulic cylinder 2 moves vertically. Centering arms are respectively provided on both sides of the indenter assembly 1 , and the two centering arms are arranged symmetrically with respect to the indenter 11 of the indenter assembly 1 .

The centering arm includes a pressing rod 3, an arm rod 4, a connecting rod 5 and a claw rod 6. The claw rod 6 is connected with the indenter assembly 1 through the arm rod 4 and the connecting rod 5 respectively, and the two ends of the arm rod 4 are respectively connected with the indenter assembly. 1 and the claw lever 6 are hinged; the two ends of the connecting rod 5 are hinged with the pressure head assembly 1 and the claw lever 6 respectively. One end of the claw lever 6 is crescent-shaped, which can facilitate the clamping of the workpiece 10 so as to achieve centering.

The arm bar 4 and the connecting rod 5 are arranged vertically, and the claw bar 6 is arranged horizontally.

One end of the pressing rod 3 is fixedly connected with the arm rod 4 through the rotating shaft 8 , and the rotating shaft 8 is rotationally connected with the pressure head assembly 1 , and the pressing rod 3 can rotate together with the arm rod 4 . The piston rod of the hydraulic cylinder 2 is provided with a vertical rod 7, one end of the vertical rod 7 is fixedly connected with the piston rod of the hydraulic cylinder 2, and the compression rod 3 (the other end) in the two pairs of arms is hinged with the other end of the vertical rod 7 .

As shown in Figures 2 to 4, when the piston rod of the hydraulic cylinder 2 moves vertically, it can drive the pressure rods 3 in the two pairs of arms to move, thereby respectively driving the respective arm rods 4 (the pressure rods 3 ) to rotate, so that The claw bars 6 in the two pairs of arms move laterally, and the two claw bars 6 move toward the workbench 9 or move outwards simultaneously.

The workbench 9 is located directly below the indenter 11, and the axes of the workbench 9 and the indenter 11 are on the same straight line. After the workpiece 10 is placed on the workbench 9 by the conveying tool (as shown in Figure 4, the workpiece 10 is not located in the middle of the workbench 9), the piston rod of the hydraulic cylinder 2 moves to make the claw rods 6 in the two pairs of centering arms simultaneously Move toward the workbench 9, thereby pushing the workpiece 10 on the workbench 9, so that the workpiece 10 is located in the middle of the workbench 9. After the position of the workpiece 10 is adjusted, the piston rod of the hydraulic cylinder 2 moves in the opposite direction so that the claw rods 6 of the two pairs of centering arms move outward at the same time. and the diameter of the workbench 9 will not affect the downward movement of the ram assembly 1.
