Press-fitting device and press-fitting method for multi-O-ring part

Abstract

The invention provides a press-fitting device and a press-fitting method for a multi-O-ring part, and relates to the technical field of industrial automatic assembly. The press-fitting device comprises a press-in mechanism, and comprises a rack, a guide assembly arranged below the rack, a movable plate installed at the bottom of the guide assembly, a plurality of pressing heads installed on the movable plate, a press-fitting air cylinder installed on the rack, a self-centering connecting piece connected with the press-fitting air cylinder and the movable plate correspondingly, and a clamping mechanism arranged below the side of the press-in mechanism; and the clamping mechanism comprises a bottom frame provided with a positioning tooling plate, a positioning clamping device and a clampingair cylinder which are installed on the positioning tooling plate, a hinge connecting head connected with the clamping air cylinder and the positioning clamping device correspondingly, a first adjusting assembly connected with the press-fitting air cylinder, a second adjusting assembly connected with the clamping air cylinder, a displacement sensor arranged on the rack in a penetrating mode, and acontroller connected with the first adjusting assembly, the second adjusting assembly and the displacement sensor. The problem that the O-shaped ring is prone to breakage in the assembling process and cause sealing failure is solved.

Description

technical field [0001] The invention relates to the technical field of industrial automation assembly, in particular to a press-fitting device and a press-fitting method for multiple O-ring parts. Background technique [0002] In product design, there are many occasions involving the use of O-ring shaft hole seals. In the process of automatic assembly, parts equipped with O-rings are assembled with counterparts, causing O-rings to be cut from time to time. This may cause major failure to the sealing function of the product, such as oil leakage, air leakage, liquid leakage and other phenomena. There are generally three types of press-fitting processes commonly used at present: [0003] 1. A large amount of lubricating oil is used to lubricate the O-ring and the hole of the opponent part to reduce the friction coefficient of the contact surface, and then use a large pressing force to press the shaft part with the O-ring into the hole of the opponent part ; [0004] 2. Desig...

AI Technical Summary

Problems solved by technology

[0007] 1. None of the three processes can completely solve the problem of O-ring damage during the assembly process, and damage is still very common during mass production; 2. All three processes are highly dependent on lubrication and consume a large amount of lubricating oil ; 3. The scope of application is limited, and it is impossible to use long tapered surface-guided tooling or design in more production and product design
