Embodiment
The embodiment of the static contact assembly dress inspection frock of a kind of isolating switch of the utility model: shown in Fig. 1-4; Be laid with guide rail 6 on the support 1 of this frock; Slidable fit has tailstock 2 on the guide rail 6; Be fixed with right alignment cubing 3 on the tailstock 2, said right alignment cubing 3 is axial direction and the consistent multidiameter of tailstock 2 moving directions, and the enlarged diameter section of this multidiameter is used for cooperating with the identical inserting of the endoporus of static contact 8; The reduced diameter section of multidiameter fixedly is inserted on the tailstock 2, enlarged diameter section is towards holder 5; On multidiameter, offer along its axial direction being used for of extending and the quiet arc contact 9 detection hole that insertings cooperate that coincide, this detection hole is a through hole, and the central axis of multidiameter is consistent with the central axis in detection hole.Be positioned at guide rail 6 end position places on the support 1 holder 5 is installed; This holder 5 is used for fixing static contact cylinder body 10; Holder 5 has the axial direction through hole consistent with the moving direction of tailstock 2; Be fitted with an end in the through hole and be fixed with the register pin of ring flange, on holder 5, offer the mounting hole with the corresponding one by one setting of pilot hole of ring flange, realize the fixing of register pin through static contact cylinder body 10 being inserted on the register pin and holder being fixedly connected with ring flange with bolt; For the central axis that guarantees static contact cylinder body 10 consistent with the central axis that detects the hole, the inserting that coincide of the through hole of said register pin and holder 5.During concrete operations; One end of static contact cylinder body 10 is inserted on the register pin; The other end of static contact cylinder body 10 is the assembling end of quiet arc contact 9 and static contact 8, after quiet arc contact 9 assembled, promotes tailstock 2 and moves; Represent promptly in the hole that the quiet arc contact 9 and the right alignment of static contact cylinder body 10 meet the demands if quiet arc contact 9 can get into to detect fully, otherwise do not satisfy; After quiet arc contact 9 assembled, static contact 8 tightened to be fixed on the static contact cylinder body 10, the sharp then right alignment that uses the same method to static contact 8 detects.
Also be fixed with stop bit frame 7 on the said support 1; Said stop bit frame 7 has the axial direction rotating shaft consistent with the tailstock moving direction 71, and slidable fit has the length cubing 4 of platy structure in the rotating shaft 71, in order to realize the length detection of static contact assembly; The sliding scale of length cubing 4 is just in time consistent with the Measurement Allowance of static contact assembly; In addition, in order not influence the assembling of static contact assembly, said length cubing 4 71 rotations around the shaft is assemblied on the stop bit frame 7.During concrete the application; The position of stop bit frame 7 need guarantee said length cubing 4 in the least limit position and the static contact assembly when allowing minimum length; Length cubing 4 can with the end face of static contact 8 contact matching just in time, therefore, length cubing 4 with static contact 8 side of joining be detection faces.
In the foregoing description; Said right alignment cubing 3 is a multidiameter; The enlarged diameter section of multidiameter 3 is to be used for the cylindrical section that cooperates with the endoporus inserting of static contact 8; In other embodiments, said right alignment cubing also can be a cylindrical section, as long as can realize and the identical inserting of the endoporus of static contact.
The foregoing description in use; Through bolt register pin is fixed on the holder 5; Then static contact cylinder body 10 is inserted on the register pin, then quiet arc contact 9 is tightened and be fixed on the static contact cylinder body 10 assembling of completion quiet arc contact 9; Promote tailstock 2 after the assembled and move, represent that promptly quiet arc contact 9 and static contact cylinder body 10 right alignmenies meet the demands if quiet arc contact 9 can enter into the detection hole of right alignment cubing 3 fully towards quiet arc contact 9; Then static contact 8 is tightened on the static contact cylinder body 10, accomplishes the assembling of static contact 8, utilize with quiet arc contact 9 and detect the right alignment that identical method detects static contact 8 and static contact cylinder body 10.After right alignment detects and finishes; Promotion length cubing 4 moves around along the rotating shaft 71 of stop bit frame 7; If during two extreme positions in its moving range of the detection faces of length cubing 4, can interfere with static contact 8, the greatest limit position can not interfere promptly and meet the demands in the least limit position.
