Abstract
The utility model relates to an E-type magnetic core air gap depth measuring instrument, wherein the tradition measurement method of E-type magnetic air gap depth is that the height of a side foot andthe height of a middle foot are respectively measured by a caliber rule, and then the difference value of the heights of the side foot and the middle foot is taken, wherein the operation is complicated, and is easy to generate errors. The E-type magnetic core air gap depth measuring instrument comprises a dial indicator or clock gauge, a measuring platform and a base, wherein the measuring platform is fixed on the base, the table-board of the measuring platform is smooth, and a small hole is arranged on the middle portion of the measuring platform, the dial indicator or clock gauge is fixed on one side of the measuring platform, and a measuring head extends to the other side of the measuring platform and can freely expand through the small hole. The E-type magnetic core air gap depth measuring instrument is greatly convenient for measuring the E-type magnetic core air gap depth, and has higher measuring precision.
Description
Technical field
The utility model belongs to the electronic product production technical field, particularly relates in the E type magnetic core product production run grinding the measurer of air gap depth survey.
Background technology
E type magnetic core for satisfying designing requirement, often needs to grind air gap as the parts of electronic product.E type magnetic core has three pin, and the pin on both sides is generally high, and middle pin is more lower slightly than the pin on both sides, and when two E type magnetic cores being formed altogether when closed circuit, middle pin opposite position will form a slit, is referred to as air gap.The depth of air gap is the important control point in the E type core production.The method of traditional measurement air gap degree of depth is: measure the height of limit pin and the height of middle pin respectively with slide calliper rule, get its difference and be the air gap degree of depth.The deficiency of this measuring method is conspicuous, and it needs twice measurement, gets its difference again, the trouble that operates, and be easy to generate error.
The utility model content
The utility model has proposed a kind of E type magnetic core air gap depth calibrator at the deficiency that above-mentioned prior art exists, and it is reasonable in design, and is simple in structure, utilizes this measuring instrument to measure the E type magnetic core air gap degree of depth, and easy and simple to handle, reading is directly perceived, the measuring accuracy height.
The technical scheme that the utility model technical solution problem is taked is: a kind of E type magnetic core air gap depth calibrator, form by dial gauge or clock gauge, measuring table and pedestal, described measuring table is fixed on the pedestal, described measuring table table top is smooth, the middle part is provided with aperture, described dial gauge or clock gauge are fixed on a side of described measuring table, and the measuring head of described dial gauge or clock gauge extends the measuring table opposite side by described aperture and can freely stretch.
Select dial gauge or clock gauge for use, main according to requirement to measuring accuracy.
Described measuring table can be horizontally disposed with, and also can vertically be provided with.When described measuring table was horizontally disposed with, described dial gauge or clock gauge were fixed on the downside of described measuring table in vertical state, its measuring head upwards, by the aperture in the middle of the described measuring table and exceed the measuring table table top; When described measuring table vertically was provided with, described dial gauge or clock gauge were the level of state and are fixed on the left side of described measuring table, its measuring head to the right, by the aperture in the middle of the described measuring table and exceed the measuring table table top.
Be the precision of guaranteeing to measure, the table top of the measuring table described in the utility model must be smooth, and requiring its flatness is 0.02mm.In the practical application, the operator gets sitting posture or stance, faces measurer; Before the measurement, earlier with a magnetic core that did not grind air gap, the measuring head propelling with dial gauge or clock gauge makes it concordant with measuring table, and dial gauge or clock gauge are made zero.During measurement, the middle pin of E type magnetic core is aimed at measuring head, the both sides pin is pressed on the table top of measuring table, then the degree of depth that can read tested E type magnetic core air gap according to dial gauge or clock gauge indicating value.
Utilization of the present utility model greatly facilitates the measurement to the E type magnetic core air gap degree of depth, and measuring accuracy can reach the purpose of effective control E type magnetic core air gap degree of depth, thereby solve the bad problem of the magnetic core that causes because of measuring error than higher.
