Description
Technical field
This utility model relates to a kind of frock clamp, is specifically related to the frock of a kind of middle-size and small-size elongated current transformer housing
Fixture.
Background technology
Current transformer principle is based on what transformer principle was made, and current transformer is by the iron core closed and winding group
Become.Its first side winding number of turn is little, goes here and there in needing the circuit of electric current of measurement, and therefore it often has whole electricity of circuit
Stream flows through, and secondary side winding turn ratio is more, is serially connected in measuring instruments and protective loop, current transformer operationally, it
Secondary side circuit all the time be Guan Bi, therefore the impedance of measuring instruments and protective loop series coil is the least, current transformer
Duty close to short circuit, current transformer is big for primary side electric current to be converted into secondary side small area analysis measure, secondary side
Can not open a way.
The outer end of current transformer is additionally provided with current transformer housing, and current transformer housing is interior hollow structure,
Production and processing is the most inconvenient.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, existing offer a kind of structure letter
The frock clamp of middle-size and small-size elongated current transformer housing single, easy to use, reasonable in design.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of middle-size and small-size elongated current mutual inductance
The frock clamp of device housing, its innovative point is: includes current transformer housing and is arranged on current transformer enclosure interior
Fixture, described fixture includes that plug, nut, bolt and lifting bolt, the two ends of described plug are symmetrically arranged with 8 nuts, institute
Stating nut and be welded on the both ends of plug, described bolt is fixedly connected with nut, the both sides end face centre bit of described plug
The place of putting is additionally provided with centre hole, and the dual-side of described centre hole is provided with screwed hole, and the number of described screwed hole is 4, described
Lifting bolt is fixedly connected with plug by screwed hole.
The beneficial effects of the utility model are as follows: this utility model is symmetrically arranged with 8 bolts on plug, passes through bolt
Plug is fixedly installed on the inner end of current transformer housing, by being threaded hole in the both ends of the surface of plug, by hanging
Plug is sling by ring screw, conveniently produces, thus substantially increases production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is mandrel structure schematic diagram of the present utility model.
Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art can be by this
Content disclosed by description understands other advantages of the present utility model and effect easily.
As depicted in figs. 1 and 2, the frock clamp of a kind of middle-size and small-size elongated current transformer housing, including current transformer
Housing 1 and be arranged on the fixture within current transformer housing 1, fixture includes plug 2, nut 31, bolt 3 and lifting bolt,
The two ends of plug 2 are symmetrically arranged with 8 nuts 31, and nut 31 is welded on the both ends of plug 2, and bolt 3 and nut 31 carry out solid
Fixed connection, the both sides end face center position of plug 2 is additionally provided with centre hole 21, and the dual-side of centre hole 21 is provided with screwed hole
22, the number of screwed hole 22 is 4, and lifting bolt is fixedly connected with plug 2 by screwed hole 22.
This utility model is symmetrically arranged with 8 bolts 3 on plug 2, by bolt 3, plug 2 is fixedly installed on electric current
The inner end of transformer housing 1, by being threaded hole 22 in the both ends of the surface of plug 2, is carried out plug 2 by lifting bolt
Sling, conveniently produce, thus substantially increase production efficiency.
Operation principle: first by the scalable threaded portion radial contraction of bolt 3 to less than in current transformer housing 1
Portion, the one end of plug 2 of slinging with driving, plug 2 is put into current transformer housing 1 internal, make plug 2 bolts at two ends 3 and electricity
Current transformer housing 1 two ends are symmetrical, then with drive a vehicle by current transformer housing 1 together with plug 2 to engine lathe, by plug 2
One crown is withstood engine lathe headstock spindle is top, and other end lathe tailstock movable thimble withstands and is fixed, and tightens up
The scroll chuck clamping plug 2 of horizontal lathe, slightly adjusts 8 bolts 3 on plug, rotates plug 2 and current transformer shell
Body 1, according to current transformer housing 1 inner circle centering current transformer housing 1 center, after making current transformer housing 1 center, weight
Newly utilize 8 bolts 3 to prop up current transformer housing 1 inwall to realize current transformer housing 1 and fasten, then carry out Current Mutual Inductance
The machining in device housing 1 end flange face, after processing one end, again turn current transformer housing 1 clamp for machining and on
Current transformer housing 1 carry out clamping by above-mentioned steps again, reprocess other end flange face.
Above-described embodiment is preferred embodiment of the present utility model, is not the limit to technical solutions of the utility model
System, as long as the technical scheme that can realize on the basis of above-described embodiment without creative work, is regarded as falling into
In the range of the rights protection of this utility model patent.
