Description

Technical Field

[0001] This invention belongs to the field of machining technology, and in particular relates to a quick clamp for flipping an ellipsoidal rotating body. Background Technology

[0002] In the production process of certain ellipsoidal bodies of revolution, it is often necessary to flip the workpiece. A common method is:

[0003] For workpieces with end frames and connection holes, the connection plate is generally designed to be bolted to the end frame and then hoisted onto a general-purpose flipping frame for flipping.

[0004] For workpieces without end frames or with no connecting holes, making connection to the workpiece impossible, a sling is used to pass through the center hole at the bottom of the workpiece. The workpiece is placed on the ground, and a crane is used to hold the sling and slowly lift one end of the workpiece. The crane is then slowly moved to the other side, and finally, the crane is slowly lowered to flip the workpiece. During the flipping process, the operator needs to support the workpiece. Although this method is simple, the workpiece is prone to swinging to both sides during the flipping process because its center of gravity is never on the flipping surface, which is very dangerous. In addition, one side of the workpiece needs to make point contact with the ground, and improper protection can easily crush the edges and damage the workpiece surface. Summary of the Invention

[0005] The purpose of this invention is to provide a quick-release fixture for flipping ellipsoidal rotating bodies, which solves the technical problem in the prior art where flipping of ellipsoidal rotating body workpieces without end frames or without connecting holes on the end frames easily causes damage to the workpiece.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] A quick-release clamp for flipping an ellipsoidal body of revolution includes a clamp body for clamping ellipsoidal workpieces. The clamp body is mounted on a universal flipping frame, and the flipping of the ellipsoidal workpiece is achieved by the movement of the universal flipping frame. The clamp body includes a support base with a supporting arc surface on the lower inner side and a mounting platform on the upper outer side. An inner pressure block is hinged to the upper part of the mounting platform, and a pressing profile is located on the lower part of the inner pressure block. In the clamping state, the ellipsoidal workpiece is located between the pressing profile and the supporting arc surface.

[0008] The present invention provides a quick clamp for flipping an ellipsoidal rotating body, wherein the inner pressure block has two outwardly extending pressure block hinge ears at the end away from the pressing and holding model, and the upper part of the mounting platform has a hinge seat corresponding to the position of the pressure block hinge ears, and the pressure block hinge ears are hinged to the hinge seat through the pressure block hinge shaft.
