Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary installation equipment for plate shape measuring instruments, and in particular to a precision measuring device for plate shape measuring instruments. Background Technology

[0002] With the rapid development of modern industry, informatization and intelligentization have become key technologies for enterprises' core competitiveness. At the same time, enterprises are demanding increasingly higher precision in production control, especially in the rolling process of silicon steel 20-roll mills in cold rolling mills. High precision is required for performance parameters such as the thickness, width, and planar shape of the strip. The strip shape gauge is one of the important pieces of equipment for achieving strip shape precision control, and its control accuracy directly affects product quality. Some domestic steel mills have experienced batch quality accidents due to significant errors in the installation accuracy of the strip shape gauge, resulting in substandard strip thickness and shape in the finished products. To address the problems of high installation precision, high difficulty, and low installation efficiency of strip shape gauges in silicon steel 20-roll mills in cold rolling mills, there is an urgent need to design a strip shape gauge precision measuring device that can quickly and accurately measure the horizontality and verticality of the strip shape gauge, improve installation and maintenance efficiency, increase production efficiency and product quality, and meet the control precision requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a plate shape meter accuracy measuring device to address the above-mentioned problems, thereby solving the technical issues of high installation accuracy, high difficulty, and low installation efficiency of traditional plate shape meters.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a plate shape measuring device, including a clamp, a support frame and a measuring device. The clamp has an openable clamping ring in the middle. One end of the support frame is fixedly connected to the clamp, and the other end is set as a mounting end for mounting the measuring device. The mounting end is inclined to one side along the direction parallel to the central axis of the clamping ring.

[0005] Furthermore, the clamp includes an upper clamping ring, a lower clamping ring, and a connecting member. The upper clamping ring is semi-circular, and upper clamping ears are provided on both sides of the upper clamping ring. Lower clamping ears are provided at both ends of the lower clamping ring. The upper clamping ears and the lower clamping ears are detachably connected by the connecting member, and the clamping ring is formed between the upper clamping ring and the lower clamping ring.

[0006] Furthermore, an upper rib plate is provided on the upper clamping ear, and the other end of the upper rib plate is fixedly connected to the outer wall of the upper clamping ring; a lower rib plate is provided on the lower clamping ear, and the other end of the lower rib plate is fixedly connected to the outer wall of the lower clamping ring.

[0007] Furthermore, the support frame includes several horizontal and vertical bars forming a stepped shape, with the uppermost horizontal bar forming the mounting end and the lowermost vertical bar being fixedly connected to the clamp.

[0008] Furthermore, it also includes several support rods, which are installed at the right angle formed by the horizontal and vertical rods.

[0009] Furthermore, the measuring device includes a lower clamping block, an upper clamping block, an outside micrometer, and a locking element. The lower clamping block is mounted on the mounting end, and the upper clamping block is mounted on the lower clamping block by the locking element. A mounting hole is formed between the lower clamping block and the upper clamping block, and the outside micrometer can be clamped and mounted on the mounting hole.

[0010] Furthermore, the central axis of the mounting hole is parallel to the central axis of the clamping ring.

[0011] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0012] 1. In use, the clamp is installed on the outer circumference of the roll of the shape measuring instrument. An auxiliary center line is set on one side of the shape measuring instrument, which is perpendicular to and horizontally set to the center axis of the roll when it is in the standard position. When the end of the outside micrometer is at its highest point, it touches the auxiliary center line. When the roll of the shape measuring instrument rotates forward and backward by the same angle, the distance between the end of the outside micrometer and the auxiliary center line is recorded. The position detection of the roll of the shape measuring instrument is achieved by the difference between the two distances. Based on the above, the present invention can quickly and accurately measure the horizontality and verticality of the shape measuring instrument, effectively solving the problems of high accuracy measurement difficulty and low efficiency in the traditional installation process, and significantly improving the installation and maintenance efficiency of the shape measuring instrument.

[0013] 2. The opening and closing mechanism of this utility model clamp is easy to disassemble and assemble. The support frame is set in a multi-stage form and equipped with support rods, which can improve the stability of the support frame. The distance can be accurately measured by using an outside micrometer. Attached Figure Description

One end of the support frame 2 is fixedly connected to the clamp 1, and the other end is set as the mounting end for mounting the measuring device 3. The mounting end is inclined to one side along the direction parallel to the central axis of the clamping ring.

[0025] In this embodiment, the clamp 1 includes an upper clamping ring 11, a lower clamping ring 12, and a connector 13. The upper clamping ring 11 is semi-circular, and upper clamping ears 14 are provided on both sides of the upper clamping ring 11. Lower clamping ears 15 are provided at both ends of the lower clamping ring 12. The upper clamping ears 14 and lower clamping ears 15 are detachably connected by the connector 13, forming a clamping ring between the upper clamping ring 11 and the lower clamping ring 12. Specifically, an upper stiffening plate 16 is provided on the upper clamping ear 14, and the other end of the upper stiffening plate 16 is fixedly connected to the outer wall of the upper clamping ring 11; a lower stiffening plate 17 is provided on the lower clamping ear 15, and the other end of the lower stiffening plate 17 is fixedly connected to the outer wall of the lower clamping ring 12.

[0026] In this embodiment, the support frame 2 includes several horizontal bars 21 and vertical bars 22 forming a stepped shape. The uppermost horizontal bar 21 forms the mounting end, and the lowermost vertical bar 22 is fixedly connected to the clamp 1. In addition, the support frame 2 also includes several support rods 23, which are installed at the right angle formed by the horizontal bars 21 and the vertical bars 22.

[0027] In this embodiment, the measuring device 3 includes a lower clamping block 31, an upper clamping block 32, an outside micrometer 33, and a locking member 34. The lower clamping block 31 is mounted on the mounting end, and the upper clamping block 32 is mounted on the lower clamping block 31 via the locking member 34. A mounting hole is formed between the lower clamping blocks 31 and the upper clamping block 32, and the outside micrometer 33 can be clamped and mounted in the mounting hole. The central axis of the mounting hole is parallel to the central axis of the clamping ring.

[0028] Please see Figures 4 to 5 For usage, please refer to the following steps:

[0029] 1. First, install the upper clamping ring 11 onto the plate shaper 4, then install the lower clamping ring 12 onto the plate shaper 4. The upper clamping ring 11 and the lower clamping ring 12 clamp the plate shaper 4 roller. Rotate the plate shaper 4 roller back and forth to find the highest point of the outer circle of the plate shaper 4 roller. Tighten the upper clamping ring 11 and the lower clamping ring 12 on the roller.

[0030] 2. Make the outside micrometer 33 perpendicular to the auxiliary center line 5 of the unit. At this time, loosen the locking part 34 and adjust the outside micrometer 33 so that the end of the outside micrometer 33 is flush with the end face of the auxiliary center line 5.

[0031] 3. Rotate the plate profiler 4 to the right and measure the horizontal distance between the end face of the outside micrometer 33 and the auxiliary center line 5 of the unit to obtain the value H1; rotate the plate profiler 4 to the left and measure the horizontal distance between the end face of the outside micrometer 33 and the auxiliary center line 5 of the unit to obtain the value H2.

[0032] 4. Calculate the parallelism measurement of the plate shaper 4 as △H = H1 - H2. The parallelism requirement is △H ≤ 0.08mm. If the △H value is positive, it means that the plate shaper 4 is offset to the right; if the △H value is negative, it means that the plate shaper 4 is offset to the left. The plate shaper 4 should be adjusted and measured again accordingly. If the △H value is 0, it means that the center line of the plate shaper 4 is completely perpendicular to the auxiliary center line 5 of the unit and completely parallel to the work roller, which meets the accuracy requirements. The installation of the plate shaper 4 is then completed.
