Abstract

The utility model relates to the technical field of rare earth processing, and particularly relates to a neodymium iron boron gridding test board. The neodymium iron boron gridding test board disclosed by the utility model comprises a bottom plate; and a mark gridding device capable of marking in a positioning manner is arranged on the bottom plate. The neodymium iron boron gridding test board is simple in structure, and meets the coating gridding detection requirements on a small neodymium iron boron product by fixing of a sample through the bottom plate, size positioning of a right-angle steel square and marking of a cutting gauge fixing grid.

Description

A kind of neodymium iron boron cross cut test plate

Technical field

The utility model relates to the rare earth processing technique field, particularly a kind of neodymium iron boron cross cut test plate.

Background technology

The development of rare earth permanent-magnetic material at present is very rapid, has obtained widespread use in a lot of fields, becomes the valuable cargo basis of up-to-date technology; Sintered NdFeB in the rare-earth permanent magnet has very high remanence strength, magnetic energy product and coercive force, this be current any permanent magnetic material can't compare, but also exist Curie point low, be easy to defective such as efflorescence corrosion.

NdFeB material improves its corrosion resistance by overlay coating in actual applications, and the adhesion of overlay coating directly influences the quality of product.Generally adopt cross to draw lattice for coating adhesion and detect, draw lattice observation coating by cutter at coating and heave, peel off situation, can judge the adhesion of coating.The detection of drawing the bigger paint type coating of the relatively more suitable area of lattice plate on the market at present, the general volume of neodymium iron boron product is less, and fixing difficulty can not adapt to the detection demand during detection; Therefore need carry out technological improvement to existing stroke of lattice plate.

The utility model content

The purpose of this utility model is at the defective of prior art and deficiency, and a kind of compact conformation, easy to operate neodymium iron boron cross cut test plate are provided.

For achieving the above object, the utility model is by the following technical solutions:

A kind of neodymium iron boron cross cut test plate described in the utility model comprises base plate, and described base plate is provided with the scale that can locate line and draws the lattice device.

Further, described scale is drawn the lattice device and is comprised that steel square cuts rule with leading, and described steel square is fixedlyed connected with base plate, leads to cut to advise and is located on the steel square.

Further, described lead cut rule comprise that fixed frame, fixed frame inboard are provided with the grid bar of arranging in length and breadth.

Further, described base plate is provided with some fixed screws, and some fixed screws are along the steel square setting, and wherein fixed screw is located at the place, summit, right angle of steel square.

Further, the outside of described fixed frame has pilot hole, and pilot hole cooperates with fixed screw fixed frame is fixed on the steel square.

Further, the width of described grid bar is 1mm.

The utility model beneficial effect is: the utility model is simple in structure, and by base plate fixed sample, steel square sizing with lead and cut rule fixed-grid line, the coating that satisfies the fritter neodymium iron boron product is drawn lattice and detected requirement.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

A kind of neodymium iron boron cross cut test plate described in the utility model, comprise that base plate 1, described base plate 1 are provided with the scale that can locate line and draw lattice device 2, scale is wherein drawn lattice device 2 and is comprised that steel square 21 cuts rule 22 with leading, steel square 21 is fixed at base plate 1 and forms coordinate axis in length and breadth, steel square 21 has certain thickness, for sample 3 fixedly provides the backer, sample 3 is arranged and is tested coating at base plate 1 upper edge steel square 21 and faces up.

Above-mentioned base plate 1 upper edge steel square 21 outers are provided with some fixed screws 11, the preferred fixed screw 11 of the utility model is three, wherein a fixed screw 11 is located on the summit, right angle of steel square 21, two long limits that then are arranged at steel square 21 in addition, described three fixed screws, 11 formation three-point fixs.

Above-mentioned leading cut rule and 22 is located on the steel square 21, lead and cut rule 22 and comprise fixed frame 23 and be arranged at the interior grid bar 24 of fixed frame 23 in length and breadth, have some pilot holes 25 on the outer of fixed frame 23, and the spacing setting of pilot hole 25 cooperates with fixed screw 11 on the base plate 1, pilot hole 25 is sheathed on the fixed screw 11, and fixed frame 23 is tightened on steel square 21 by nut.

Above-mentioned grid bar 24 width that arrange in length and breadth are 1mm, fixed frame 23 inner rings are provided with groove, grid bar 24 moves up and down about can be respectively on fixed frame 23 grooves, after grid bar 24 moves to counter sample 3 tops, draws the lattice test along 24 pairs of sample 3 surfaces of grid bar.

The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
