Three-jaw expansion floating pressure head

Abstract

The invention provides a three-jaw expansion floating pressure head, comprising a floating deviation correcting device, wherein the floating deviation correcting device comprises a supporting plate (6), balls (7), a bolt (8), rubber elastic rings (9), lower supporting seats (10), balls (11), an upper supporting seat (12) and a shaft (13). The invention has the following beneficial effects: in thepressing process, central deviation is automatically corrected through spherical surface contact of the rolling body and elastic deformation of the rubber elastic rings; the lower supporting seats (10) and a pressure head body (3) pass the pressing force; an electromagnet push rod (4) and three-jaw expansion supporting hooks (1) are installed in the pressure head body (3); and if the pressure head encounters end surfaces of blind holes or stepped holes, the three-jaw expansion supporting hooks (1) retract to avoid interference with the end surfaces of the holes during pressing. The pressure head can realize rapid grabbing and clamping of bearings or shaft sleeves and the bodies of the similar structure and realize pressing of the bearings or shaft sleeves on the blind holes, stepped holes, through holes, etc.

Description

technical field [0001] The invention relates to a three-claw telescopic floating pressure head used for clamping and pressing of bearings or shaft sleeves. Background technique [0002] Bearings or bushings can be press-fitted with a press during assembly, or manually installed with an assembly sleeve and a small hammer. Manual installation is inefficient and labor-intensive; pressing with a press requires a special pressure head for pressing. The traditional indenter can only realize simple press-fitting work. In the press-fitting process, the bearing or bushing needs to be manually positioned in the bearing hole of the shell to be pressed-fitted. It is difficult to realize automatic assembly, the efficiency is low, and the press-fitting accuracy is difficult to guarantee. .

Manual installation is inefficient and labor-intensive; pressing with a press requires a special pressure head for pressing

The traditional indenter can only realize simple press-fitting work. In the press-fitting process, the bearing or bushing needs to be manually positioned in the bearing hole of the shell to be pressed-fitted. It is difficult to realize automatic assembly, the efficiency is low, and the press-fitting accuracy is difficult to guarantee.

[0003] Although there is the emergence of center deviation self-adaptive internal clamping telescopic indenter, it uses the support block and telescopic slider on the indenter to realize the grasping and clamping of bearings or bushings and similar structures, because it is more wasteful. The material and processing and assembly structure are relatively complex, and have not been widely promoted and applied.
