摘要:
Cette invention concerne un procédé et un appareil pour l'usinage des pointes tronconiques des électrodes (1, 2) situées dans un pistolet ou presse à souder par points ou dans un dispositif semblable. Suivant le procédé, chaque pointe d'électrode est usinée à la fois sur sa surface tronconique latérale (1a, 2b) et sur sa surface d'extrémité (1b, 2b). Dans une première étape d'usinage, la pointe d'électrode est introduite dans une cavité située dans un premier outil (20, 21) pour usiner la surface latérale (1a, 2a) ou la surface d'extrémité (1b, 2b) jusqu'à ce que l'une de ces deux surfaces vienne heurter une butée, après quoi la pointe d'électrode, dans une seconde étape d'usinage, est introduite dans une cavité située dans un deuxième outil (21, 20) pour usiner la surface d'extrémité (1b, 2b) ou la surface latérale (1a, 2a) jusqu'à ce que la surface qui a été usinée au cours de la première étape d'usinage vienne heurter contre une butée. Selon l'invention, l'appareil comprend un outil rotatif motorisé (20) pour usiner la surface latérale tronconique (1a, 2a) et un deuxième outil rotatif motorisé (21) pour usiner la surface d'extrémité (1b, 2b) de la pointe d'électrode. Le premier outil (20) est équipé d'une butée destinée à la surface d'extrémité (1b, 2b) de la pointe d'électrode, et le deuxième outil (21) est équipé d'une butée destinée à la surface latérale (1a, 2a) de la pointe d'électrode.
摘要:
A cutting device for trimming a selected peripheral edge portion of a lens (33) secured in a mold (2) which comprises a housing (44) having an extended support member (46); a cutting means (56) having a cutting edge (58); said support member having a guiding edge (54) disposed a fixed distance from said cutting edge (58); and said guiding edge (54) and said cutting edge (58) being cooperatively associated so that when said guiding edge (54) contacts the outer wall or a mold (2), the cutting edge (58) will be positioned for the precision trimming of an edge portion of a lens (33) secured on the mold (2).

A preferred embodiment of the present invention is directed to a detachable flexible handle (30) for a power hand tool (20) and an attachment system associated with the handle and the tool for releasably attaching either a rigid or the flexible handle (30) to the power hand tool (20). The system has housing (22) attachment recesses (38, 42) on the tool that receive attachment clips (52, 54) located at opposite end portions of the flexible handle (30) or structure of a rigid handle (32).
摘要:
An attachment (10) adapted to be mounted to the nose piece of the rotary tool or to the outer end of a flexible drive extension is disclosed. The attachment (10) encircles the collet and bit at the base end portion of the attachment and has an extension portion (58) that extends along the length of the bit and partially encircles it, providing a planar surface (72) that limits the depth of engagement by the bit during operation. Also the extension has a semi-cylindrical surface portion (68) that contacts a smooth outer end portion of the cutting bit and and provides support to the bit so that it cannot be deflected and cut into the extension portion of the attachment. A recess in the back of the attachment is adapted to provide a surface into which the end of a user's thumb may rest for the purpose of applying downward force to the attachment during operation.
