Problems solved by technology

When installing the cylindrical pin, it often happens that the cylindrical pin is installed obliquely and the pier is thick. When the cylindrical pin is used for positioning, the installation will not be installed and the assembly cannot continue. The reason is that the cylindrical pin is pressed into the assembly hole by a press. When the cylindrical pin and the assembly hole are not guaranteed to be on the same straight line, there is a component force perpendicular to the assembly hole, which will cause the cylindrical pin to be thickened or installed obliquely.

Abstract

The invention discloses a universal fixture for pin assembly. The universal fixture comprises a bottom plate, a stand column and a cover plate, the stand column is fixedly arranged on one side of theupper surface of the bottom plate, the cover plate is fixedly arranged at the top end of the stand column, a groove is formed in the upper surface of the cover plate, a movable block is movably arranged in the groove, a pressing plate is arranged on the upper part of the movable block, the pressing plate is fixedly connected with the cover plate, through holes are formed in the upper surface of the movable block and the upper surface of the inner part of the groove correspondingly, and guide sleeves are sleeved with the through holes. According to the universal fixture for pin assembly, when acylindrical pin is assembled, the coaxial matching degree of the cylindrical pin and an assembly hole can be improved, the movable block is movably arranged in the groove of the cover plate and can freely move and rotate on the horizontal plane in the groove, and therefore it is guaranteed that the guide sleeves and a pressing rod are always in a vertical state, so that inclination of the cylindrical pin is limited, the conditions of inclined installation and upsetting of the cylindrical pin are avoided, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of mechanical processing devices, in particular to a universal fixture for pin assembly. Background technique [0002] In industrial production, it is often necessary to install a cylindrical pin on a workpiece. After the cylindrical pin is assembled, the cylindrical pin needs to be used for positioning later. When the cylindrical pin and the pin hole belong to an interference fit, the cylindrical pin is required not to be tilted during installation. When installing the cylindrical pin, it often happens that the cylindrical pin is installed obliquely and the pier is thick. When the cylindrical pin is used for positioning, the installation will not be installed and the assembly cannot continue. The reason is that the cylindrical pin is pressed into the assembly hole by a press. , it cannot be guaranteed that the cylindrical pin and the assembly hole are on the same straight line, and there is a component for...
