Document Type and Number:
WIPO Patent Application WO/2021/056237
Kind Code:
A1
Abstract:
An apparatus (100) and method for mounting an O-ring (200) to a work piece (300). The apparatus (100) comprises a guiding component (101) comprising a frustum portion (1011) adapted to be arranged coaxially with a groove (302) formed on an end surface (301) of the work piece (300) for receiving the O-ring (200), a large end face (1012) of the frustum portion (1011) arranged adjacent to the end surface (301); a plurality of through slots (102) each extending a predetermined distance radially from an edge of the large end face (1012); and a pressing component (103) comprising a plurality of fingers (1031) each adapted to be fitted in and moved along the corresponding through slot (102) to push the O-ring (200) that is placed on the frustum portion (1011) into the groove (302), wherein a diameter (D) of the large end face (1012) is larger than an inner diameter of the groove (302) to allow the O-ring (200) to be expanded at the large end face (1012) and to shrink to be received in the groove (302) with pressing of the plurality of fingers (1031). With the apparatus (100) comprising through slots (102) formed on the frustum portion (1011) and fingers (1031) each fitted in and moved along the corresponding through slot (102), the O-ring (200) which has a smaller diameter than or same as that of the groove (302) for receiving it can be well received in the groove (302)automatically without human intervention, increasing the degree of automation and thus the mounting efficiency and accuracy.
