Problems solved by technology

At present, there is excess steel production capacity in the world, which has led to higher and higher requirements for the quality of rolls in steel mills. The symmetry of flat heads is a link that is difficult to control in detail and cannot be tested normally by conventional methods. Therefore, major roll companies aim at This issue is urgently awaiting resolution

Embodiment 1

[0016] Such as figure 1 A detection device for the symmetry of a roll flat head as shown, comprising No. 1 dial gauge 1, No. 2 dial gauge 2, No. 3 dial gauge 3 and support 4, said No. 1 dial gauge 1, No. 2 dial gauge Dial gauge 2 and No. 3 dial gauge 3 are fixed above the bracket 4, No. 1 dial gauge 1 is located in the middle, No. 2 dial gauge 2 and No. 3 dial gauge 3 are set on both sides of No. 1 dial gauge 1, The distance between No. 2 dial gauge 2 and No. 1 dial gauge 1 is equal to the distance between No. 3 dial gauge 3 and No. 1 dial gauge 1. There are two support frames 401 below the support 4, and the support frames 401 are respectively connected to The bracket 4 has an included angle.

Embodiment 2

[0018] Referring to Example 1, the angle between the support frame 401 and the support frame 4 is 60°.

Embodiment 3

[0020] The detection method of the flat head symmetry of the roll: After determining the thickness of the flat head of the roll with the outer micrometer, use the detection device of the flat head symmetry of the roll, place it horizontally on the flat head of the roll, keep the dial indicator perpendicular to the surface of the roll, and then Shake left and right to find the 0 reference point in the No. 1 dial gauge, use this reference point as a reference line, use the depth gauge to match the vertical distance from the detection device to the flat head, and record data A; check the No. 2 reference point at the 0 reference point The readings of the dial gauge and the No. 3 dial gauge are used to understand the error in the horizontal direction, which side deviates more, after the measurement of the front section, move the instrument to the back section of the flat head, and check each thousand points at the 0 reference point The reading of the meter indicates the direction fo...

Abstract

The invention discloses a roll flat head symmetry degree detection device. The device comprises a first dial indicator, a second dial indicator, a third dial indicator and a support; the first dial indicator, the second dial indicator and the third dial indicator are fixed to the upper portion of the support, the first dial indicator is located in the middle, the second dial indicator and the third dial indicator are arranged on the two sides of the first dial indicator, the space between the second dial indicator and the first dial indicator is equal to the space between the third dial indicator and the first dial indicator, two support frames are arranged on the lower portion of the support, and the included angles exist between the support frames and the support. The invention further discloses a detection method of the detection device. Accordingly, in the measurement process, the platform reference problem does not need to be considered, the dial indicators are adopted, and the precision is improved; the middle indicator of the three dial indicators can determine the center datum, and the height difference of two planes is determined stably and accurately; the data is more visual compared with a traditional measurement method, and calculation is not needed.

Description

technical field [0001] The invention belongs to the field of steel product manufacturing, and in particular relates to a detection device and a detection method for the symmetry of a roll flat end. Background technique [0002] With the development of the times, all walks of life are developing in the direction of high, precise and sharp product quality control. At present, there is excess steel production capacity in the world, which has led to higher and higher requirements for the quality of rolls in steel mills. The symmetry of flat heads is a link that is difficult to control in detail and cannot be tested normally by conventional methods. Therefore, major roll companies aim at This issue is urgently awaiting resolution. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to provide a method for detecting the symmetry of the flat end of a roll in view of the deficiencies in the prior art. [0004] Technical solution: ...
