Description
Technical field
The present invention relates to a kind of coil of strip measuring method, a kind of steel coil end-face bleeding edge measuring method is particularly related to.
Background technology
In strip coiling process, because helping the reasons such as volume belt tension is improper, precision of equipment installation is not high to cause finished steel
Roll up end face not concordant, produce steel coil end-face bleeding edge.To meet strict demand of the user to steel coil end-face bleeding edge size, improve
Final product quality, coil of strip must be measured before dispatching from the factory to bleeding edge, that is, measure bleeding edge to the distance and spilling of coil of strip outmost turns
Side exceeds the accurate dimension of steel coil end-face.There is problems with the current measurement to steel coil end-face bleeding edge size：1) in industry,
In the market can not find specific purpose tool or relatively good alternative instrument；2) using steel ruler, the alternative instrument measurement accuracy such as clearance gauge compared with
Difference；3) to improve precision, when being measured using steel ruler and clearance gauge, operate relatively complicated, it is often necessary to two people's conjunction measurings, wherein one
Steel ruler (length 500mm-1000mm or so) chi face is vertically placed on steel coil end-face and its side is compacted along coil diameter direction by people,
The gap that another person is surveyed between steel ruler side and coil of strip with clearance gauge.
The content of the invention
It is an object of the invention to provide a kind of high, the easy to use steel coil end-face bleeding edge measuring method of measurement accuracy.
To achieve the above object, the steel coil end-face bleeding edge measuring scale designed by the present invention, including rod support, main scale and trip
Mark.The main scale is vertically fixed on rod support, and the vernier is connected on main scale by slide rail and can slided on main scale.It is described
Be provided with secondary ruler on vernier, the secondary ruler be connected to by slide rail on vernier and can along main scale vertical slip.The secondary ruler
Front end is provided with probe, and the probe is flake, and its thickness is slightly less than individual layer belt steel thickness, can be according to individual layer belt steel thickness more
Change the probe of different-thickness；It is relatively thin due to popping one's head in, it is easily damaged in measurement, therefore a number of probe need to be equipped with case more
Change.Rebounding mechanism is additionally provided between the vernier and secondary ruler, the rebounding mechanism uses V-arrangement shell fragment, the card of the V-arrangement shell fragment
Between vernier seat and secondary ruler, for resetting secondary ruler and withdrawing probe.
The bottom (part contacted with coil of strip) of the rod support or rod support are integrally made by permanent-magnet materials, can be adsorbed on
On coil of strip surface.Two Magnetic ruler pin are provided with the rod support, the Magnetic ruler pin includes turning arm and magnetic block.The rotation
The two ends of pivoted arm are rotatably attached on magnetic block and rod support respectively.
Be provided with side by side on the rod support in two rotating shafts (rotating shaft is not rotated in itself), two rotating shafts be respectively arranged with
The bearing that rotating shaft coordinates a, part for the outer ring of the bearing is fixedly connected with turning arm, and gear is cased with another part.Two axles
The gear intermeshing held is consistent the anglec of rotation of two turning arms, to realize the synchronous rotary of two Magnetic ruler pin.
Rebounding mechanism is additionally provided between the vernier and secondary ruler, for resetting secondary ruler to withdraw probe.Rebounding mechanism can
From elastomeric elements such as spring, V-arrangement shell fragments.Secondary ruler, which is slided and extrudes V-arrangement shell fragment, by taking V-arrangement shell fragment as an example, during measurement makes V-arrangement shell fragment
Two ends draw close, V-arrangement shell fragment is restored and secondary ruler is recovered to initial position after measurement, and now probe is withdrawn inside vernier, is played
Protect the effect of probe.
In addition, the top of the secondary ruler is provided with graduation mark, graduation mark according to precision need can using single graduation mark or
Similar to the two-scale line of slide measure；The main scale is according to whether measurement bleeding edge is determined to the distance of coil of strip outmost turns
It is fixed that whether graduation mark is set.
As a kind of preferred scheme, the lock-screw for vernier being locked on main scale is provided with the vernier.
As a kind of preferred scheme, the end of the main scale is provided with block, for avoid vernier in slipping from
Come off on main scale.
As a kind of preferred scheme, the one side that the rod support is contacted with coil of strip is inner concave, i.e. both sides protrusion, middle to chi
Seat contract.Because coil of strip outer peripheral surface is circular arc camber, the contact area of rod support and coil of strip can be increased using inner concave, it is to avoid
Rod support double swerve, increases the stability of measuring scale.
As a kind of preferred scheme, the connection between the magnetic block, turning arm is hinge connection.
Surveyed invention also provides one kind using such as steel coil end-face bleeding edge according to any one of claims 1 to 5
The steel coil end-face bleeding edge measuring method that gage is measured, comprises the following steps：
1) traverse measurement chi makes right-angle surface in main scale be close to the end face of coil of strip, and makes the center of circle of main scale sensing coil of strip, will
Rod support is inhaled on coil of strip outer ring, and putting down two Magnetic ruler pin makes two magnetic blocks inhale on coil of strip outer ring.
2) after measuring scale fixing-stable, moving cursor passes through the locking screw being arranged on vernier to the position for needing to detect
Vernier is fixed on measurement main scale by nail；
3) top of secondary ruler is gently pressed, after probe contacts end face of coil of strip measured by secondary ruler, by secondary ruler
Graduation mark can directly read steel coil end-face bleeding edge exceed steel coil end-face actual size；
4) in previous step, rebounding mechanism pushes generation elastic deformation by secondary ruler, when unclamping secondary ruler, due to rebounding mechanism
Reaction force, secondary ruler move up recovery and will probe suction vernier in.
The beneficial effects of the invention are as follows：The steel coil end-face bleeding edge measuring scale that this method is used is measurement finished steel coils end
The specific purpose tool of face bleeding edge size, the distance of the measurable bleeding edge of main scale to coil of strip outmost turns, the measurable bleeding edge of secondary ruler surpasses
Go out the accurate dimension of steel coil end-face；The magnetic block at Magnetic ruler pin two ends is made using permanent-magnet materials, is firmly adsorbed by magnetic force
In coil of strip outer ring, stable connection is easy to use.
