Description

Technical Field

[0001] The utility model relates to the technical field of automatic forging robots for shaft forgings, in particular to an automatic forging robot for shaft forgings. Background Art

[0002] As the national economy develops and infrastructure construction speeds faster and faster, the domestic demand for forging robots is also increasing. At present, with the advancement of the industry, the demand for forging robots is diversified, such as the extension and retraction of the clamping mechanism. Therefore, the diversified development of forging robots has become very important, which is related to the improvement of the national industrial level. The existing robot-specific grippers, when in use, are retracted by the cylinder piston, and the lower ends of the left and right grippers are supported outward by the hinge, the fixed axis does not move, and the upper ends of the left and right grippers are pressed inward, so that the part material handle is clamped by the movable clamp. When it needs to be loosened, the external cylinder is reversed to complete the clamping and loosening process. However, this method of providing power through the extension and retraction of the cylinder piston takes a long time to provide power, which wastes time and reduces work efficiency. At the same time, it is difficult to clamp special-shaped parts, which are easy to fall during the clamping and moving process, making it inconvenient to use.

[0003] The application number is 201921298763.3, which discloses a forging robot, including a first mechanical gripper and a second mechanical gripper; the first mechanical gripper includes a mechanical gripper seat, the upper surface of the mechanical gripper seat is fixedly connected to a fixed block, the upper surface of the fixed block is provided with a slide groove, two trapezoidal clamping blocks are slidably connected to the slide groove, a bidirectional motor is provided inside the fixed block, the two output ends of the bidirectional motor are connected to a rotating plate, and both ends of the rotating plate are connected to the fixed block through a rotating shaft; the second mechanical gripper includes a fixed block. The forging robot can clamp special-shaped parts to prevent them from falling during the clamping and moving process, and is easy to use.

[0004] However, there is a shortcoming. When the robot clamps shaft parts, the clamping device contacts the cylindrical surface of the shaft parts, and the contact area is small, which may cause the parts to fall off. Utility Model Content

[0010] Furthermore, a first protrusion is fixedly connected to the bottom of one side of the slide plates that are close to each other, and a threaded barrel is fixedly connected to the slide plate, the threaded barrel is located directly above the first protrusion, a screw is threadedly connected inside the threaded barrel, one end of the screw is rotatably connected to a second protrusion, the second protrusion is located between the two slide plates, the other end of the screw passes through a circular hole and is fixedly connected to a knob, and the screw is slidably arranged inside the circular hole.

[0011] Furthermore, one end of the connecting plate away from the second connecting seat is rotatably mounted on the second protrusion.
