Problems solved by technology

The flat head is a structure in which both ends of the roll protrude from the roll body. There are many factors that affect the flat head during the forming process. Therefore, the symmetry of the flat head is a detail that is difficult to control. The traditional technology is basically based on measuring the height difference. The aspect is relatively low and cannot be accurately detected, so the major roll companies are eagerly waiting for a solution to this problem

Embodiment 1

[0024] Such as figure 1 A roll flat head symmetry detection device shown includes a base 1, a rotatable and locked bracket 2 fixed on the base 1, and a dial indicator 3 fixed at the end of the bracket; the bracket 2 includes a tubular upper Support 21 and tubular lower support 22, one end of the lower support 22 is fixed to the base 1, and the other end has a No. 1 through hole 23; one end of the upper support 21 has a No. 2 through hole 24 with the same diameter as the No. 1 through hole 23, The other end fixes the dial indicator 3 through the fixture 4 fixedly connected with it; the No. 1 through hole 23 and the No. 2 through hole 24 run through the rubber tube sleeve 5 with internal thread at the same time, and the inside of the rubber tube sleeve 5 is connected with the internal thread through the internal thread. The screw mandrel 6 is screwed together, and one end of the screw mandrel 6 fixes the rotating handle 7; the clamp 4 is in a 7-shape or N shape, and the clamp 4 ...

Embodiment 2

[0026] Referring to Example 1, the inside of the clamp has a trapezoidal cavity that accommodates the straight rod at the end of the dial indicator.

Embodiment 3

[0028] Referring to Example 1, the base is a square plate of 200*200mm, the length of the upper bracket and the lower bracket shown are the same, both are 200mm, and the cross-sectional diameter of the upper bracket and the lower bracket is 50mm.

[0029] Example 3:

[0030] Such as image 3 The detection method for the symmetry of the flat head of the roll shown is: make the whole roll vertical to the ground, keep the flat head of the roll perpendicular to the ground at the same time; fit the bottom surface of the base of the detection device to the flat side of the flat head of the roll, and rotate the upper bracket so that After the sub-meter head touches the outer circle of the roll neck, the operator manipulates the rotary handle to screw the screw and the rubber sleeve to fix the upper and lower brackets, and at the same time fix the dial indicator head. The operator stands on the roll Roll neck end face side translation detection device, when the detection device moves...

Abstract

The invention discloses a device for detecting the symmetry degree of the palm end of a roller. The device comprises a pedestal, a support fixed on the pedestal, and a dial gauge fixed in the end portion of the support; the support comprises a tubular upper support and a tubular lower support; one end of the lower support is fixed to the pedestal, and the other end of the lower support includes afirst through hole; one end of the upper support includes a second through hole whose diameter is the same with that of the first through hole, and the other end of the upper support fixes the dial gauge via a clamp fixedly connected; and a rubber tube sleeve with internal threads penetrate the first and second through holes, the internal of the rubber tube sleeve is in screwed with threads of a screw rod, and a rotating handle is fixed in one end of the screw rod. The invention also discloses a detecting method of the detecting device. After that the pedestal of the device is fit to the planar surface of the palm end, the support drives the dial gauge to measure the height of the palm end, height difference between palm ends in the two ends of the roller is obtained, and the symmetry condition of the palm end in the same side of the roller is derived.

Description

technical field [0001] The invention belongs to the field of iron and steel manufacturing, and in particular relates to a roll flat end symmetry detection device and a detection method thereof. 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 flat head is a structure in which both ends of the roll protrude from the roll body. There are many factors that affect the flat head during forming. Therefore, the symmetry of the flat head is a detail that is difficult to control. The traditional technology basically focuses on measuring the height difference. The aspect is relatively low and cannot be accurately detected, so the major roll companies are eagerly waiting for a solution to this problem. Conten...
