Abstract

PURPOSE:To enable accurate measurement of distortion and deviation of a roll by grabbing one end of a roll with a plural point support chuck free to rotate to support it horizontally and accurately centering. CONSTITUTION:One end of a layer roll 1 is supported overhung being grabbed with a plural point support chuck 2 while the other end thereof is diriven to rotate with a drive motor 4 through a sprocket 3. A measuring roll 8 of a distortion measuring gauge 6 comprising a dial gauge 17 and a measuring contactor 7 is brought into contact with the circumferential surface of the roll 1 to rotate it 1 being heated in a thermal treatment furnace 9 so that the center of the roll 1 is adjusted accurately with the plural point support chuck 2 and the distortion measuring gauge 6. This enables accurate measurement of the roundness of the roll 1 while eliminating measuring errors due to chattering as the measuring roll 8 contacts it 1 thereby enabling accurate measurement of distortion and deviation of the roll.

Description

[Detailed description of the invention] The present invention relates to a roll strain measuring device K.

The case of a rare roll, which is the most preferred embodiment of the roll, will be explained below.

The lower roll Lll is approximately 650 mm in glass manufacturing (in
Rotating part in the heat treatment furnace (9) at ℃! , I found out that it was ilJ,
The strain on the four sides (-JLII) greatly affects the quality of the crow.Therefore, when manufacturing the rare roll +j), in the final process, the rare roll is It is necessary to rotate (1) and actually measure its strain or deflection.

Therefore, conventionally, measuring devices as shown in FIGS. 1 to 3 have been used. That is, the sleeves tlo] (11) are fitted on both ends of the rare roll +1), and both sleeves Qo)
(11) is placed on the rotatable pairing 0-ra (13) supported by the pairing 0-ra support (12), and the Suzu rocket ( 3) The K chase (5) was being rotated by one foot.

However, as shown in Figure 2, the number of three (lO) is
4) Since it is fixed to the rare roll (1+panel), there is some wobbling, and the center of the sleeve (101 (II) and the center of the rare roll (1) are misaligned, the rare roll it)
When rotated, the rare roll f++ rotates eccentrically, and if the direction of seciter shift is different on the left and right, the rare roll +1
1 is swung left and right and is not perpendicular to the original strain measurement. Also, since the sleeve flo) (II) is only placed on the pairwise roller (13)', there is some wobbling, and due to the tension of the chaser (5), the sleeve flo) (II), in addition to the rare roll (1), There was a drawback that the sides rose up. History, Three Zu (10) iM 115)
Attach the hair reciprocating roller (ke) to the rare roll (1
) in the thrust direction, but there was also some wobbling. For this reason, in the past, these looseness, errors, tolerances, etc.
It was not possible to accurately measure the + strain and the runout of the outer 14 plane during rotation.

The Kihatsu I call was made in view of the shortcomings of the conventional example mentioned above, and its purpose is to provide a three-point support chisek or a four-point support chisek in the (sh, ah) roll support part.
By using a multi-point support device such as a force point support device, the roll can be supported horizontally and accurately centered, making it possible to accurately measure roll strain and distortion. To provide a strain measuring device.

Hereinafter, the present invention will be explained in detail with reference to the accompanying drawings. (2) is a multi-point support chiset, such as a three-point support chiset, a four-point support chiset, or a force-point support chuck, used in lathes, etc., and is installed at the tip of the roll chissef l-J6j and is rotatable. There is. The puller roll (f+) is supported in a cantilevered manner with one end held by the support screw (2) by 4〆℃'. is supported horizontally to ensure perpendicularity with the measuring contact (7) of the strain meter (6), and as a result of this, the cessister is accurately aligned, and the rare roll f1.) is accurately aligned with the center circumference. It will rotate.At the other end of the rare roll (1) there is a suzuroket (3
) is attached, and is rotationally driven via a chaser v (51) by a continuously decelerating drive motor (4) installed in the heat treatment furnace (9). 6) consists of a tie cell gauge 07) and a measuring contact (7) made of a quartz tube, and a perfectly circular measuring roller (8) made of ceramic is rotatably provided at the tip of the measuring contact (7). The measurement contact (7) is slidably inserted into the furnace wall of the heat treatment furnace (9) (support pipe (I9) provided by the government),
The measuring roller (8) is brought into contact with the outer peripheral surface of the rare roll (1) perpendicularly. Oka is placed in the upper Bearishig case of the heat treatment furnace (9) 1), l! - The lower bearing case (a pairing case installed between the figures and the rare case delivered into the heat treatment furnace (9)) rotates smoothly without rubbing against the furnace wall (18). I have to. The rare roll (1) is heated while being heated in the heat treatment furnace (9).
When you rotate it, it's a rare roll! If +) is not a perfect circle, the measurement contact (7) will slide and fluctuate, and the needle of the tie cell gauge (17) will swing, detecting distortion. Point-supported chisek (
2) Because it is gripped by the selter, there is no wobbling in the thrust direction, it can be supported horizontally, and the verticality of the strain meter (6) can be accurately measured, and the selter can be accurately aligned and rotated around the selter precisely. The roundness of the rare roll can be accurately measured because the rare roll f1) can be set accurately in this way, in case the rare roll m is lifted due to the tension of the thienyl (5). Also, measurement contact (7)
Since the measuring roller (18) at the end of the roller (18) is brought into contact with the outer periphery of the thinner roll (1), there is no possibility of scratching the thinner roll f1), and there is an advantage that measurement errors due to vibration can be eliminated. , Rare roll (1) and other sea;s
It may be used as a Jitter, or it may be supported with a Hi-D block.

Furthermore, the present invention can of course be applied to the above-mentioned round rolls, and can also be applied to other continuous rolls.

As mentioned above, Kizori J grips one end of the roll with a multi-point support structure, which simplifies the support structure of the roll, and also allows for accurate leveling and alignment, and there is no wobbling due to errors or tolerances. This has the advantage that strain can be measured accurately.

Furthermore, unlike the conventional method, there is no need to attach or remove sleeves, and rolls can be set easily and quickly.
