A sealing ring assembly device

Abstract

The invention discloses an assembly device for a seal ring. The assembly device comprises a locating assembly part and floating assembly jigs which are arranged up and down, wherein the floating assembly jigs are of three-layer structures; clamping locating mechanisms are arranged at the uppermost layers; the lower two layers adopt vertical crossed linear slide rails, so that the uppermost layers have finite degrees of freedom in the X and Y directions; before seal ring assembly, a locating cone head in the locating assembly part is inserted into a product for guide locating, floating in the X and Y directions is limited, and the to-be-assembled product is forced to be coaxial with the locating cone head and a charging head; and then, the seal ring on the charging head passively slides downwards to a groove of the to-be-assembled product, and assembly is completed. According to the assembly device, a two-time locating manner is utilized, the precision requirement on a rotary disc driving part, a horizontal carrying module and a vertical carrying module is greatly reduced, and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of product installation, in particular to the installation of sealing rings. Background technique [0002] In the absence of industrial visual aids, the sealing ring must be assembled to the product in the form of "blind assembly". The form of blind loading requires that the charging head and the product are smoothly docked (coaxial) without offset, so that the sealing ring can slide smoothly from the charging head to the product to be loaded. However, in order to save costs, the accuracy of the moving parts of the product clamping equipment to be loaded is not high, coupled with the accumulation of errors, the possibility that the product to be loaded is always repeatedly positioned at the same assembly position is very low, and the loading head is at the assembly position. The repeat accuracy is not high; if the assembly is directly aligned, it may cause the loading head and the product to be installed to...

AI Technical Summary

Problems solved by technology

However, in order to save costs, the precision of each moving part of the product clamping equipment to be loaded is not high. In addition to the accumulation of errors, it is very unlikely that the product to be loaded will always be repeatedly positioned at the same assembly position. The repetition accuracy is not high; if it is assembled directly, it may cause the loading head and the product to be installed to be out of concentricity, which will eventually lead to assembly failure
