Description

Detect the tool of lower link in breaker of plastic casing four-bar mechanism

Technical field

The utility model belongs to a kind of detection instrument of circuit breaker part, more particularly to one kind be suitable for 100A, The tool of lower link in the detection breaker of plastic casing four-bar mechanism of 160A breaker of plastic casing product.

Background technique

Lower link 1 (such as Fig. 1) plays key as the important part in molded case circuit breaker mechanism, to product combined floodgate characteristic Effect, four-bar mechanism closed a floodgate execute breaker closing reliability when dead point and dual power supply are converted also can be because of the matter of lower link Amount is horizontal and changes, and when 2,7 pitch-rows of tie rod holes are larger, then product was not easy dead point, causes mechanism to close a floodgate unreliable, Instantly when 2,7 pitch-rows of tie rod holes are smaller, then mechanism cannot equally cross dead point, false combined floodgate be caused, so the conjunction of lower link pitch-row Lattice degree drastically influences breaker of plastic casing product quality, and still, lower link part small volume itself is detected gaging hole concentricity Can because lower link two-arm it is not parallel due to can not accurately detect, it is necessary to what one kind limited its benchmark first can directly feed back inspection Survey the cubing of result.

Summary of the invention

The utility model is technical problem present in solution well-known technique and its benchmark can be limited first by providing one kind The tool of lower link in the detection breaker of plastic casing four-bar mechanism of testing result can directly be fed back.

The utility model is adopted the technical scheme that solve technical problem present in well-known technique: it includes tire Tool, briquetting, the first inspection axis and the second inspection axis；The mould is an approximate long cube shaped mould main body, the mould Two side views that long and flash is constituted in the long cube of main body are can be just by the long arm in the two sides of detected lower link The mould stepped ramp type two sides that the medial surface divided is bonded completely therewith；There are also perforation institutes on the mould stepped ramp type two sides State front and back two mould through-holes equal in magnitude of mould stepped ramp type two sides；When by the long arm in two sides of the detected lower link Divide medial surface to be bonded completely with mould stairstepping two sides as previously described, and connects the quilt on the detected lower link Detect the two sides of the lower link long-armed lower plane of connecting plate and the height of the side of the mould main body cuboid and broadside structure At plane be bonded completely when, former and later two described mould through-holes then just with the two sides of the detected lower link it is long-armed on Front and back two holes equal in magnitude coincide unanimously；In addition, in the long plane constituted with broadside in the upside of the mould main body, There are one inverted T-shape grooves in plane i.e. below the connecting plate long-armed with the two sides of the detected lower link；Institute The briquetting stated is a three-dimensional inverted T-shape block, and the inverted T-shape block can agree with completely just and there are the insertions in gap In the inverted T-shape groove of the mould main body, there is a C font notch on the T-shaped perpendicular road of the inverted T-shape block, it will When the inverted T-shape block is inserted into the mould main body, lateral road on the upside of the C word of the C font notch on the inverted T-shape block Partial lower plane is just pressed in the company as previously mentioned, the detected lower link being fitted in the mould main body completely In the upper plane of fishplate bar；The diameter of the first inspection axis is can be just logical across the big mould in front side described in the mould main body Hole；The diameter of the second inspection axis is that can pass through small mould through-hole on rear side of the mould main body just, and described first and second examines The length of axis is the thickness long-armed plus the two sides of the detected lower link greater than side thickness wide in the cuboid of mould main body Sum total.

The utility model has the advantages and positive effects of: the tool have it is easy to operate, it is easy to process (be used only line Cutting and mill processing can be completed), the features such as being easy to carry about with one, be convenient for storage, and cost is extremely low, and utilization rate is high, according to preliminary system Meter is 25 times of height gauge auxiliary gauge block detection, greatly improves work efficiency, reduce labor intensity.

Specific embodiment

For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates Detailed description are as follows for attached drawing:

As shown in Fig. 1,2,3,4,5,6, firstly, to detect the hole 2 in detected lower link 1 to hole 7 linear distance (because Hole 2 and hole 7 in the same horizontal line, so only detecting their horizontal distance), it is necessary to fixed reference, first will fall T Font briquetting 22 is embedded in the groove 19 of 11 inverted T-shape of mould, at this time the bottom of the T-shaped lateral road 26 in inverted T-shape briquetting 22 Portion agrees with 19 bottom 20 of groove of the inverted T-shape in mould 11 completely and just there are gap, and the perpendicular road in briquetting 22 is A perpendicular road i.e. its neck 18 of the groove 19 of inverted T-shape in its neck 27 and mould 11 agrees with substantially and there are gaps, owns Gap is not more than 0.10mm, and briquetting 22 is pushed to the middle rear side of mould 11, briquetting along the inverted T-shape track 19 in mould 11 The vertical range of 22 pushing plane 28 and the upper plane 13 of mould 11 is exactly equal to be detected the thickness of the connecting plate 6 of lower link 1 Degree, by detected lower link 1 be placed among mould 11 and be detected the bottom surface 8 of the connecting plate 6 of lower link 1 just with mould 11 When upper plane 13 is bonded completely, two front side arms, 5 inside for being detected lower link 1 is bonded with two leading flanks 17 of mould 11, is detected It surveys 1 liang of posterolateral arm of lower link, 3 inside to be bonded with two trailing flanks 14 of mould 11, wherein being detected hole 7 and the mould 11 of lower link 1 Hole 16 be aligned, the hole 2 for being detected lower link 1 is aligned with the hole 12 of mould 11, at this point, being detected 1 mesoporous 2 of lower link to hole 7 Between horizontal distance be exactly equal to 11 mesoporous 12 of mould to hole 16 distance.By briquetting 22 along the inverted T-shape track of mould 11 It slides into, at this point, the pushing plane 28 of briquetting 22 is just pressed in the upper plane of the connecting plate 6 of detected lower link 1, at this point, will It examines axis 21 and examines hole 12,16 and detected lower link 1 of the axis 29 respectively from any side of detected lower link 1 through mould 11 Hole 2,7 and run through, if can all pass through, then it is assumed that pitch-row is qualified, and is detected on 1 two sides of lower link long-armed 9 Hole 2 and hole 2, hole 7 and hole 7 are coaxial.So far, the critical size of the part is accredited as qualification.Remaining size is blanking size, can It does not detect or can be detected with other methods, without lifting an eyebrow.
