Bonding device for unframed oil seal

Abstract

The invention discloses a bonding device for an unframed oil seal. The bonding device comprises first connecting pieces, second connecting pieces, a first pressing plate, a second pressing plate, a third pressing plate and a fourth pressing plate. The first pressing plate and the second pressing plate are connected through the first connecting pieces. The third pressing plate and the fourth pressing plate are connected through the first connecting pieces. The first pressing plate and the fourth pressing plate are connected through the second connecting pieces, and a gap for operating is reserved between the first pressing plate and the fourth pressing plate. The second pressing plate and the third pressing plate are connected through the second connecting pieces, and a gap for operating isreserved between the second pressing plate and the third pressing plate so that the gap width can be adjusted when the pretightening force of the second connecting pieces is adjusted. According to the bonding device for the unframed oil seal, the special cutting and bonding device is designed according to the structure characteristics of the unframed oil seal, a cutting datum plane is provided inthe cutting process, and therefore the cutting stability is higher and the cutting face quality is better; and in the bonding process of the oil seal, the pressing plates at the two sides of the oilseal are not dismantled, and the consistency and stability of the oil seal in the cutting and bonding processes are guaranteed.

Description

technical field [0001] The invention relates to the technical field of mechanical structure sealing, in particular to a skeletonless oil seal bonding device. Background technique [0002] As a typical representative of oil seals, skeletonless oil seals are widely used in mechanical transmission fields such as engine crankshafts, gearboxes, differentials, shock absorbers, etc. There are generally two installation methods, integral type and cutting and bonding type. According to the sealing principle of the frameless oil seal, the installation of the oil seal requires high surface quality, dimensional accuracy, especially the accuracy of the lip position. [0003] At present, there are cutting and bonding tools for sealing strips on the market, which can ensure the cutting and bonding accuracy of sealing strips in non-working environments. However, due to the differences in sealing principles, shape structures, materials, The installation accuracy requirements and usage occas...

Problems solved by technology

[0003] At present, there are cutting and bonding tools for sealing strips on the market, which can ensure the cutting and bonding accuracy of sealing strips in non-working environments. However, due to the differences in sealing principles, shape structures, materials, The installation accuracy requirements and usage occasions are different, and the cutting tools for sealing rubber strips are not suitable for cutting and bonding of skeletonless oil seals.

The existing sealing strip bonding tools can only be operated in a flat environment with a large space, and cannot be operated in a working state (that is, the sealing surface and the sealing cavity). The practicability is not high, and it is not suitable for skeletonless oil seals. Due to the special environment and structure of the frameless oil seal, there is no special tool for the frameless oil seal.
