Installation device for rotary oil seal

Abstract

The invention relates to the technical field of rotary oil seals, and discloses an installation device for a rotary oil seal, which includes a workbench, a transport assembly and a pressure head assembly. Below the component, a mounting plate is fixedly connected to the workbench, and the first telescopic electric cylinder is connected through the mounting plate. The lower part of the first telescopic electric cylinder is fixedly connected with the pressure head assembly. The body is provided with a feeding assembly and an extrusion assembly. The first shell is fixed with an annular extrusion chamber and a feeding chamber. The feeding assembly is movable on the top of the feeding chamber. The feeding chamber is equipped with multiple rotary oil seals. The feeding chamber The bottom is connected with the bottom of the extrusion chamber, and the invention can carry out batch press-fitting of the rotary oil seal on the factory assembly line, the press-fit is stable, the sealing performance is strong, and the rotary oil seal will not rebound.

Description

technical field [0001] The invention relates to the technical field of rotary oil seals, in particular to a device for installing rotary oil seals. Background technique [0002] Rotary oil seal (oilseal) is the customary title of general seals, simply put, it is the seal of lubricating oil. It is a mechanical element used to seal grease. It isolates the parts that need to be lubricated from the output parts in the transmission parts, so as not to let the lubricating oil leak. The common motor casing is equipped with a rotating oil seal installation groove. The rotating oil seal passes through the pressure The installation device is assembled in the installation groove to avoid leakage of lubricating oil. [0003] The utility model patent of Chinese Patent Publication No. CN210939078U discloses an installation device for a rotary oil seal, including a pressure head, a rotary oil seal, a magnet, a box body, and a base; the pressure head is located inside the box body, and the...

AI Technical Summary

Problems solved by technology

[0005] First, in the above-mentioned patent, the rotary oil seal can be pressed into place in only one step by the pressure head, but the rotary oil seal will rebound due to its own elasticity, causing the rotary oil seal to warp from the installation groove, affecting the sealing effect, and one-step press installation In this way, it is easy to crush the rotary oil seal, resulting in damage to the internal structure of the rotary oil seal and reduced sealing performance;

[0006] Second, when the rotary oil seal enters the installation groove, the edge of the protrusion above the installation groove will inevitably scratch the rotary oil seal, causing damage to the rotary oil seal and affecting the sealing effect, and even if the edge of the protrusion above the installation groove If there are impurities, the damage of the rotary oil seal will be more serious;

[0007] Third, in the above-mentioned patents, only one rotary oil seal can be press-fitted at a time for the press-fitting of the rotary oil seal. After the press-fitting is completed, the rotary oil seal needs to be filled again, and then the rotary oil seal is press-fitted into the motor installation groove, and the press-fitting speed is slow. , unable to carry out assembly line batch press-fitting in the factory
