Description
Technical field
The utility model relates to a kind of measurement mechanism, relates in particular to a kind of metallic article defectoscopy device.
Background technology
In production field of metallurgy; some metallic article; for example general cold product; location for the length direction of coil of strip edge fault after uncoiling does not have related request; and some metallic article, for example electrical steel product is because of its specification thin (between 0.23～0.65mm caliper zones), compares general cold product more to pay attention to the limit and split defective; therefore in order to ensure the carrying out smoothly of the relevant operation of unit, need split on the length direction after the uncoiling the coil of strip limit of some kind and position.
At present, producing unit and take extensive style control for the location of coil of strip edge fault when coil of strip is in the scroll state, when locate as needs, all is by in addition anticipation estimation of experience by the field operation personnel.Yet thisly be inaccurate,, often make the anticipation result have many uncertain factors, can't become of the data reference of coil of strip edge fault in band steel length direction location because field operation personnel's operant level is uneven by the method for manually estimating.If do not position and defective is not split on the limit of coil of strip end face, then the coil of strip edge fault can't support for the data that provide that the coil of strip edge fault is located on band steel length direction after the unit uncoiling on the coil of strip.
Summary of the invention
The purpose of this utility model provides a kind of coil of strip limit and splits dip stick, it is used for when steel band is in the scroll state, edge fault is measured and located, and it realizes location to edge fault by measuring edge fault apart from the angle of the distance of coil of strip circle and coil of strip central vertical line.
In order to realize the foregoing invention purpose, the utility model provides a kind of coil of strip limit to split dip stick, and it comprises:
One cross frame, it has a center disk and four feets, and described four feets stretch out from center disk, are the cross setting, and the circumference of described center disk is provided with angle index, and described feet is the rod member of hollow;
Four expansion links, correspondence is located in described four feets respectively, is respectively equipped with a flexible member between the tail end of described each expansion link and each feet;
One connects rotating shaft, and it has one first end and one second end, and first end of described rotating shaft is connected with the circle centre position of described center disk, and described connection rotating shaft can be rotated along its how much axle center, and described connection rotating shaft is provided with a graticule that axially is provided with;
One tape measure, it is fixedly connected at the circle centre position of tape measure with described second end that is connected rotating shaft, and promptly the circular flat of the circular flat of described tape measure and center disk be arranged in parallel.
Dip stick is split in use in this coil of strip limit, cross frame is put into the coil of strip inner ring, realize the location, the center of circle of coil of strip inner ring, owing to be provided with flexible member between expansion link and the feet, therefore cross frame can be stuck in the coil of strip inner ring, and this moment, the center of circle of center disk was exactly the center of circle of coil of strip.The rotating shaft that is rotatably connected then makes the graticule that connects in the rotating shaft align with edge fault, and the angle value of graticule correspondence is the angle information of edge fault on the center disk at this moment.Because tape measure is with to be connected rotating shaft fixedly connected, so tape measure turned over identical angle synchronously with the connection rotating shaft, can also utilize tape measure to record the air line distance of edge fault apart from the coil of strip center of circle at this moment, and this distance is the range information of edge fault.
Preferably, described flexible member is a spring.
Dip stick is split on coil of strip described in the utility model limit, it is by measuring the steel band edge fault that manifests on the coil of strip end face apart from the angle that turns over and the edge fault of coil of strip vertical center line have been realized edge fault apart from the distance in the coil of strip center of circle accurate location, it is simple in structure that dip stick is split on this coil of strip limit, avoid safeguarding, easy to use, cost of manufacture is cheap, but can realize the accurate measurement of edge fault position.
Description of drawings
Coming that below in conjunction with the drawings and specific embodiments dip stick is split on coil of strip described in the utility model limit is described further.
Fig. 1 splits the three-dimensional structure diagram of dip stick for coil of strip described in the utility model limit.
Fig. 2 splits the front view of dip stick for coil of strip limit shown in Figure 1.
Fig. 3 splits the side view of dip stick for coil of strip limit shown in Figure 1.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, coil of strip limit in the present embodiment is split dip stick and is comprised: cross frame, it has a center disk 1 and four feets 2, four feets 2 stretch out from center disk 1, are the cross setting, and the circumference of center disk 1 is provided with angle index 4, feet 2 is the rod member of hollow, be respectively equipped with expansion link 3 in it, be provided with spring between expansion link 3 and the feet 2, make expansion link 3 in feet 2, to stretch.Connect rotating shaft 5 and be used to connect tape measure 6 and center disk 1, an end that connects rotating shaft 5 is connected with the circle centre position of center disk 1, and connecting rotating shaft 5 can relatively rotate with central turnplate, the other end that connects rotating shaft 5 is fixedlyed connected with tape measure 6, tape measure 6 rotations synchronous with it in connecting rotating shaft 5 rotating process connect rotating shaft 5 and are provided with a graticule that axially is provided with.
Dip stick is split in use in this coil of strip limit, cross frame is put into the coil of strip inner ring, realize the location, the center of circle of coil of strip inner ring, owing to be provided with flexible member between expansion link 3 and the feet 2, therefore cross frame can be stuck in the coil of strip inner ring, and this moment, the center of circle of center disk 1 was exactly the center of circle of coil of strip.The rotating shaft 5 that is rotatably connected then makes the graticule that connects in the rotating shaft 5 align with edge fault, and the angle value of corresponding graticule is the angle information of edge fault on the central turnplate 1 at this moment.Because tape measure 6 is with to be connected rotating shaft 5 fixedly connected, so tape measure 6 turned over identical angle synchronously with connection rotating shaft 5, pulls out gage outfit 61 at this moment from tape measure 6, just can record the air line distance of edge fault apart from the coil of strip center of circle.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
