Embodiment Construction

[0009] As shown in the figure, the assembly device for the spiral retaining ring for holes includes an indenter 1 and a guide cone 2. The indenter 1 is T-shaped, the lower part is conical, and the guide cone 2 is annular. The taper is matched with the taper, the indenter 1 is provided with a guide pin 3 extending downward, and the guide cone 2 is provided with a hole, and the guide pin 3 can pass through the hole on the guide cone 2, so that the indenter 1 Vertical movement, the length of the generatrix of the conical surface of the indenter 1 is not less than the length of the generatrix of the inner conical surface of the guide cone 2, so as to ensure that the conical shape of the indenter can move to the lower part of the guide cone; the guide cone 2. The lower part is provided with a step, and the step is matched with the inner hole of the shaft 5 to be installed with the spiral retaining ring 4, and is extended to the installation position of the spiral retaining ring 4. ...

Abstract

The invention relates to a device for assembling a spiral check ring for a hole. The device comprises a pressure head and a guide cone. The pressure head is in a T shape, and the lower portion of the pressure head is conical; and the guide cone is annular, and the inside of the guide cone is in a cone shape matched with the cone shape of the pressure head. A guide pin extending downwards is arranged on the pressure head, and the guide pin can penetrate a hole in the guide cone and enables the pressure head to perpendicularly move. A step is arranged at the lower portion of the guide cone, and the step is in clearance fit with a shaft inner hole of the to-be-installed spiral check ring and extends to the installing position of the spiral check ring. The device has the beneficial effects of being simple in structure, convenient to use and the like, and the assembling efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a spiral retaining ring assembly device, which is especially suitable for assembling the spiral retaining ring for holes. Background technique [0002] In order to avoid the axial movement of the parts in the hole, the axial limit will be considered in the design, usually a spiral retaining ring is installed at one or both ends of the hole. In the process of installing the spiral retaining ring, due to the small installation space, small volume and high elasticity of the spiral retaining ring, manual installation of the spiral retaining ring is not only low in assembly efficiency, but also labor-intensive. Contents of the invention [0003] The object of the present invention is to provide a device for assembling a spiral retaining ring for holes. The device has the advantages of convenient use and simple operation, and can greatly improve the assembly efficiency. [0004] The specific technical solution of the present inven...
