Description
Technical field
The utility model belongs to a kind of detection instrument of moving contact of plastic-shell circuit breaker system, particularly relates to a kind of turnover bracket detection fixture.
Background technology
The testing of the current turnover bracket for 1250A breaker of plastic casing product, there is problem.Turnover bracket (18) (as Fig. 1) is parts that process by staking process, its three basic supports comprise: left socle (16), right support (17), medium-height trestle (13) utilize they self multiple irregular how much holes by riveting-rack (7) Jiang Fanggang (1) together with their impermeable rivetings, and three neutrals (50) between basic support are equated, now square thick stick (1) becomes the benchmark of turnover bracket (18), all dimensional parameters on turnover bracket (18) are all related with square thick stick (1).Turnover bracket (18) is opened distance, the excess of stroke, end pressure and is affected the important spare part of four-bar mechanism action as affecting moving contact in breaker of plastic casing, play a part crucial to the operating characteristic of moving contact, the variation of its 3 position of positioning hole directly affects the motion of moving contact and whole four-bar mechanism, and the operating characteristic of reliability, stability and the four-bar mechanism of breaker of plastic casing clearance between open contacts, the excess of stroke, end pressure all can change because of the quality level of turnover bracket.But, the volume of turnover bracket parts own is larger, positioning reference plane is little, entirety right alignment requires high, and it is a lot of to detect size, especially 2 the position as bindiny mechanism's system in Fig. 1 is because it is for being clipped in the middle of two limit supports, cannot use the ordinary measring tool direct-detections such as slide calliper rule, in addition, as the hole 4 connecting to the mounting bracket for being connected with breaker of plastic casing pedestal of turnover bracket location, 5, 6 position dimensions are to ensure that turnover bracket can correctly be arranged on the size on pedestal, moving contact mounting hole 3, 11, the position dimension in 20 hole is to ensure that moving contact is correctly arranged on the size on turnover bracket, hole 10, the 12nd, for coupling shaft being penetrated from the left and right sides to the significant dimensions of hole 2 to ensure that four-bar mechanism is correctly connected with turnover bracket, in order to ensure that four-bar mechanism is driving moving contact when work to ensure that mechanism can cross dead point, ensure the distance of opening of contact system simultaneously, the excess of stroke, end pressure all can meet the needs of product design, these positions are significant points of guaranteeing that turnover bracket plays a role in mechanism, in the time checking these sizes, all needed to use the auxiliary piece of testing of some in the past, and because volume of part is larger, can be difficult to dominated by hand stable by fixed position, cause measurement difficulty huge, though use the auxiliary block operations of testing, still can not ensure accurate location, detection error is unavoidable, in addition the position of 2 in Fig. 1 is difficult for using marking-out rule in the middle of being sandwiched in, the measurers such as slide calliper rule are directly measured, be difficult to quantize its deviation with height gauge line, making to measure difficulty further increases.Generally speaking, the above simple mode by gauge block auxiliary positioning can not accurately detect nine important sizes such as 4,5,6,3,11,20,10,12,2, and speed is extremely slow, not only affects benefit, and easily causes detection error.Therefore must a kind ofly first limit the cubing that can directly feed back testing result of its benchmark.
