Description
Technical field
The invention belongs to a kind of testing tool, particularly relate to a kind of cubing and using method of thermal trip of breaker of plastic casing.
Background technology
The delayed release of TM30-100 breaker of plastic casing, to be formed by a plurality of weld parts, gusset, coil, thermal element wherein arranged, be flexible coupling, bimetallic temperature sensing element, have on temperature-sensing element in a threaded hole use set screw will be installed, adjustment for Extended Time Tests, after forming electrical apparatus release, temperature-sensing element threaded hole and very big as the difficulty of getting up of the position probing between the gusset of reference for installation.The first, the component part of these parts is a lot, can not find suitable reference field with the measurement of physics chi, second, because each component part is thin, bonding area is little, be flexible coupling therein in addition, make this parts flexibility very strong, can be moved during measurement, and be difficult for holding steadily, be difficult to hold measuring accuracy, this size precision prescribed on automatic inspection line is higher, so be necessary to use cubing to be measured, reaches the detection line application requirements.
Summary of the invention
The present invention provides a kind of simple to operate, easy to process, the cubing of the thermal trip of the breaker of plastic casing be easy to carry about with one and using method for solving the technical matters existed in known technology.
The technical scheme that the present invention takes for the cubing of the thermal trip of breaker of plastic casing for the technical matters existed in the solution known technology is: it includes the body of cuboid, there is a downward dark groove at middle part at the length direction of the upper surface of the short transverse of described body, the dark groove length direction of described body each side have one by an one width side on to the cuboid groove fallen in described body, position and spatial relationship between described several groove are: when the little gusset that will be detected electrical apparatus release is placed in the lower plane of described body upper left side cuboid groove, when the large gusset of detected electrical apparatus release is placed in to the lower plane of cuboid groove in right side on described body, the dark groove of described body just in time can hold being flexible coupling and little gusset of detected electrical apparatus release, temperature-sensing element, coil, the part that thermal element and large gusset are connected mutually, and other parts that detected electrical apparatus release is flexible coupling just in time are positioned at outside the dark groove of described body, other parts of detected trip coil are in described left groove, on the lower plane of the rectangle left and right sides groove of described body, convex and two detents are arranged respectively in addition, the position of described convex and two detents is, when the little gusset that will be detected electrical apparatus release is placed in the lower plane of described body upper left side cuboid groove, the large gusset that will be detected electrical apparatus release and is placed in the lower plane of cuboid groove in right side on described body, a downward outstanding part and the pilot hole on large gusset are arranged on the lower plane of the connection hole of the use that is connected with external output web joint on the pilot hole on the detected little gusset of electrical apparatus release and large gusset, and outstanding part is just in time mutually chimeric with them downwards, in addition respectively more than the upper plane of described cuboid left and right groove the left and right sides part of the described body of part the detection through hole of one left and right directions is respectively arranged, described detection with the difference in height on the center line in the Wei，Qi hole, position of through hole and the upper plane of large gusset and with the poor difference in height for the center line of just in time hole of adjusting screw being installed with detected electrical apparatus release temperature-sensing element upper end and the upper plane of large gusset of the above the horizontal range at center of the connecting hole that downward outshot is arranged of large gusset and consistent with the poor design load of the above the horizontal range at center of the connecting hole that downward outshot is arranged of large gusset, in addition respectively more than the upper plane of described cuboid left and right groove the left and right sides of described body of part the one left and right screw that leads to straight down described left and right groove is respectively arranged from the upper plane of described body height direction, be described convex under the screw of the described body of the above part of described left groove, and be to be connected the detent of connection hole of use on described large gusset with external output web joint under the right screw of the described body of the above part of described right groove, in addition, also include coordinate described left and right screw upper end with the left and right screw of handle and the detected electrical apparatus release in jail is little, n shape briquetting and the circular pressure handle of large gusset for pushing up, one can, through the locating shaft of the detected large gusset pilot hole of electrical apparatus release, also include one and can successively through described detection, use the inspection rod of through hole.
The present invention for solving the technical matters that exists in known technology for the technical scheme of the using method of the cubing of the thermal trip of described breaker of plastic casing is: will be detected electrical apparatus release is placed on cubing, then passing with described locating shaft the pilot hole that is detected the large gusset of electrical apparatus release inserts in the detent on the lower plane of the rectangle right groove that is embedded in described body, being connected the connecting hole of use with external output web joint on, the large gusset of described detected electrical apparatus release adds a cover described circular pressure handle, right screw with the described right screw with handle through described body compresses described circular pressure handle, the coil that again two legs of described n shape briquetting is striden across to detected electrical apparatus release is placed on the little gusset be entrenched on described convex, left screw with the described left screw with handle through described body compresses on the crossbeam of described n shape briquetting, after this excellent two of the described left and right detection that penetrates described body upper end of described inspection is used in through hole, if described inspection rod can be qualified through the adjustment screw hole that is detected electrical apparatus release temperature-sensing element upper end simultaneously, on the contrary defective.
Advantage and good effect that the present invention has are: this cubing has simple to operate, (only using line cutting and mill processing to complete) easy to process, be easy to carry about with one, and the characteristics such as is convenient to deposit, and cost is low, utilization factor is high, and according to the preliminary statistics, its detection speed is 20 times of tripleplane's instrument detection speed, it is 25 times that height gauge detects, greatly improve work efficiency, reduced labour intensity, saved greatly cost simultaneously.Through using checking, wrong, loss is almost 0.
