Description
Technical field
The invention belongs to a kind of testing tool, particularly relate to a kind of cubing and method of application of thermal trip of breaker of plastic casing.
Background technology
The delayed release of TM30-100 breaker of plastic casing; Be to be welded by a plurality of parts; Gusset, coil, thermal element wherein arranged, be flexible coupling, the thermometal temperature-sensing element, have a threaded hole to want the install adjustment screw in using on the temperature-sensing element, be used for the adjustment of 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, since each component part thin; Bonding area is little, is flexible coupling therein in addition, makes that this parts flexibility is 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 measure, 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 that is easy to carry about with one and method of application for solving the technical matters that exists in the 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 that exists 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, in the dark groove length direction of said body a cuboid groove that in said body, falls on by an one of which width side is arranged each side; Position and spatial relationship between said several groove are: when the little gusset with electrical apparatus release to be detected place the lower plane of said body upper left side cuboid groove, when the big gusset of electrical apparatus release to be detected is placed the lower plane of cuboid groove in right side on the said body; The dark groove of said body just in time can hold the part that is flexible coupling and is connected each other with little gusset, temperature-sensing element, coil, thermal element and big gusset of electrical apparatus release to be detected; And other parts that electrical apparatus release to be detected is flexible coupling just in time are positioned at outside the dark groove of said body, and other parts of trip coil to be detected are then in described left groove; Protruding and two detents in location are arranged respectively on the lower plane of the rectangle left and right sides groove of said body in addition; Positions protruding and two detents, described location do; When the little gusset with electrical apparatus release to be detected places the lower plane of said body upper left side cuboid groove, when the big gusset of electrical apparatus release to be detected is placed the lower plane of cuboid groove in right side on the said body, has the outstanding part of an outstanding part and the pilot hole on the big gusset just in time chimeric each other with them downwards downwards on the lower plane of the connection hole of the usefulness that is connected with external output web joint on pilot hole on the little gusset of electrical apparatus release to be detected and the big gusset; In addition respectively on the groove of the described cuboid left and right sides plane respectively have a right-to-left also can detection from left to right use through hole with the left and right sides of the said body on top part; Detect to use the position of through hole to do about said, the difference in height on the center line in its hole and the last plane of big gusset and with the above the horizontal range difference at center of the connecting hole that downward outshot is arranged of big gusset for the center line and the difference in height on the last plane of gusset and consistent with the above the substandard design load at center of the connecting hole that downward outshot is arranged of big gusset greatly in the hole of adjustment screw just in time are installed with electrical apparatus release temperature-sensing element to be detected upper end; In addition respectively on the groove of the described cuboid left and right sides plane with left and right sides plane on said body height direction of the said body on top respectively have one lead to said left and right sides groove straight down left and right sides screw; Is that described location is protruding in described left groove under with the screw of the said body in top, and is to be connected the detent of connection hole of usefulness on the described big gusset with external output web joint under the right screw of described right groove with the said body in top; In addition, also include the upper end that cooperates said left and right sides screw have the left and right sides screw of handle and be used to push up that firm electrical apparatus release to be detected is little, the n shape briquetting of big gusset and circular pressure handle; The locating shaft that can pass the big gusset pilot hole of electrical apparatus release to be detected also includes one and can successively pass the inspection rod that detects through hole about said.
The present invention for solving the technical problem that exists in the known technology for the technical scheme of the method for using of the cubing of the thermal trip of described breaker of plastic casing is: electrical apparatus release to be detected is placed on the cubing; The locating hole that passes the big gusset piece of electrical apparatus release to be detected with described locating shaft is inserted in the detent on the lower plane of the rectangle right groove be embedded in said body then;, the big gusset piece of described electrical apparatus release to be detected adds a cover described circular pressure handle being connected the connecting hole of usefulness with external output connecting plate on; The right screw that passes said body with the described right screw that has handle compresses described circular pressure handle; The coil that two legs of described n shape briquetting are striden across electrical apparatus release to be detected is placed on and is entrenched on the little gusset piece of described location on protruding again, and the left screw that passes said body with the described left screw that has handle compresses on the crossbeam of described n briquetting; After this described inspection rod is penetrated that two detections are qualified with in the through hole if described inspection rod can pass the adjustment screw hole of electrical apparatus release temperature-sensing element to be detected upper end simultaneously about described body upper end described, on the contrary defective.
Advantage and good effect that the present invention has are: this cubing has simple to operate, and (only using line cutting and mill processing to accomplish) easy to process is easy to carry about with one; Characteristics such as be convenient to deposit, and cost is low, utilization factor is high; According to the preliminary statistics, its detection speed is 20 times of tripleplane's appearance detection speed, is 25 times that height gauge detects; Improve work efficiency greatly, reduced labour intensity, practiced thrift cost simultaneously greatly.Through using checking, wrong, loss is almost 0.
