Abstract

The utility model relates to a measuring device for measuring the moderate and opening extent which is composed of a measuring arm with a tube structure and is provided with scale staff gauge, a central orientation pin is fixed at the center of the measuring arm which has a flexible structure, two measuring heads which are provided with a measuring head body and a guide rod are connected with the measuring head respectively; wherein, the outer side of the measuring is arc-shaped, and the guide rod is arranged on the two ends of the tube on the measuring arm to form a flexible structure; and a gradienter is arranged on the measuring arm. The measuring arm also comprises a cursor pin. The utility model can accurately and fast measure the moderate and opening extent on of a vertical roller under the site condition; demarcating for the moderate and opening extent of the vertical roller can be carried out according to the measuring data, thereby avoiding the differences on the steel strip width caused by the defection, board disfiguration and inaccurate opening extent due to the poor moderate of the vertical roller. The utility model can increase the precision and efficiency on demarcating the moderate and opening extent.

Description

To moderate and aperture measurement device

Technical field

The utility model relates to a kind of measurement mechanism, particularly to moderate and aperture measurement device.The utility model is the measurement mechanism of a kind of hot strip continuous-rolling machine vertical miller to moderate and aperture, use this device under the condition of production scene, can measure edger roll easily, exactly, avoid the edger roll die misalignment to cause band sideslip of steel and flatness defect and the inaccurate strip width that causes of aperture overproof moderate and aperture.

Background technology

Edger roll moderate is meant the deviation of active side edger roll to the distance of milling train center line and transmission side edger roll to the distance of milling train center line.So-called edger roll to the bad finger of moderate both sides is unequal to the distance of milling train center line, can cause the sideslip of band steel when rolling.So-called edger roll aperture is inaccurate to be meant that the aperture that shows in the aperture of edger roll reality and the operation screen is inconsistent, and this can cause when rolling the control of strip width overproof.Owing to having produced reasons such as zero drift, the position of the wearing and tearing of edger roll both sides or edger roll can cause misaligning of edger roll inaccurate in the actual production with aperture.In order to eliminate above-mentioned two kinds of situations, need regular opposite roller moderate and aperture are demarcated.

Edger roll aperture and the centering scale method of deciding are: at first measure both sides edger roll branch and be clipped to the distance of milling train center line and the distance between the edger roll of both sides, according to the data of actual measurement the data in the operation screen are revised then.Edger roll centering degree and aperture measurement are normally directly measured one-sided edger roll to the distance of milling train center line and the distance the edger roll of both sides by survey crew with tape measure or ruler in actual production.The problem that this measuring method mainly exists is:

Because the edger roll roll surface is an arc surface, and, adopt ruler or tape measure manual measurement can't accurately find datum mark on the roll surface, cause the error of measurement big because wearing and tearing are normally rough.

During manual measurement, owing to be with the distance between two cambered surfaces on the chi manual measurement space or measure the distance of single cambered surface to straight line, can't guarantee the accuracy measured with the ruler measurement, the inclination of for example measuring ruler will produce bigger error.

Need to measure the measurement that just can finish moderate and aperture for three times, the efficient of measurement is low.Because on-the-spot space is narrow and small, environmental baselines such as high temperature, steam are relatively poor, and the working strength of survey crew is big.

Summary of the invention

The purpose of this utility model is to design a kind of to moderate and aperture measurement device, measure exactly, apace under the condition at the scene edger roll to moderate and aperture, carry out the demarcation to moderate and aperture of edger roll according to measurement data, avoid edger roll overproof the bad band sideslip of steel and flatness defect and the inaccurate strip width that causes of aperture of causing of moderate.Improve precision and the efficient of edger roll to moderate and aperture demarcation.

For achieving the above object, the technical solution of the utility model is,

To moderate and aperture measurement device, comprise, gage beam, it is a pipe structure, which is provided with graduated scale; The centralized positioning pin is fixed in gage beam central authorities; Two measuring heads comprise the measuring head body respectively and connect guide rod on it that this guide rod is inserted in the body two ends of gage beam respectively, forms stretching structure; Level meter is arranged on the gage beam.

Further, the external side of the measuring head of described measuring head circular arc.

Also be provided with the vernier pin on the described gage beam again.

Described centralized positioning pin is a telescopic structure.

The measuring head cambered surface can make gage beam keep good, stable contacting with the edger roll roll surface, guarantees that gage beam is vertical with the milling train center line, and the chi end contacts the measuring error that causes when having avoided adopting ruler to measure with roll surface.

Centralized positioning pin length can be stretched, and is applicable to the edger roll of differing heights, by the centralized positioning pin this device accurately is placed on the center line of milling train.

Level meter can make this measurement mechanism maintenance level, guarantees that gage beam is vertical with the edger roll roll surface.

The slip gage beam can move along the graduated scale direction, can measure when edger roll is in any opening degree, simultaneously measuring head is closely contacted with roll surface.

Graduated scale and vernier pin can directly be read the distance of both sides edger roll to the milling train center line.

The beneficial effects of the utility model

By the stretching structure and the external side of the measuring head circular arc of gage beam, can measure easily and fast, exactly edger roll to moderate and aperture.

Embodiment

Referring to Fig. 1～Fig. 3, of the present utility model moderate and aperture measurement device are comprised, gage beam 1, it is a pipe structure, which is provided with graduated scale 8; Centralized positioning pin 4 is fixed in gage beam 1 central authorities, and this centralized positioning pin 4 is a telescopic structure; Two

measuring heads

2,3 comprise measuring

head body

21,31 respectively and connect

guide rod

22,32 on it, measuring

head body

21,31 lateral surfaces 211,311 circular arcs; This

guide rod

22,32 is inserted in the body two ends of gage beam 1 respectively, forms stretching structure; Level meter 5 is arranged on the gage beam 1; Also be provided with

vernier pin

6,7 on the described gage beam 1.

During use, at first the centralized positioning pin 2 with measurement mechanism is placed in milling train center line markings place, and the height of adjusting pilot pin makes it to adapt with the height of roll; Being placed in level meter 5 on the measurement mechanism by observation adjusts measurement mechanism and makes measurement mechanism maintenance level, adjust gage beam 1 left and right

sides measuring head

2,3 then, measuring

head body

21,31 cambered surfaces are leaned against on the edger roll roll surface of both sides, the position readings of

vernier pin

6,7 on graduated scale 8 represented the distance of both sides roll roll surface to the milling train center line at this moment, and the result of the addition of both sides reading represents the actual aperture of roll.

Whether edger roll is to moderate in passable the learning of reading by both sides relatively, the actual aperture that shows can judge whether the edger roll aperture exists error on aperture by relatively actual measurement and the operation screen, and then can utilize by the data opposite roller of this device actual measurement moderate and aperture are demarcated.
