Description

Technical Field

[0001] The utility model belongs to the technical field of roll profile measurement, and more specifically relates to a roll profile measurement device. Background Art

[0002] Rollers are primarily used to roll metal, changing its shape and size while also increasing its strength and hardness. As crucial components of rolling mills, rollers play a crucial role in industrial production. The quality and shape of the rollers significantly impact product shaping, quality, and production efficiency.

[0003] Currently, most steel companies rely on CNC roll grinders to measure roll profile. While these machines offer high roll profile measurement accuracy, they require heavy lifting equipment such as overhead cranes to place the rolls on the grinders, making them inconvenient to operate. Furthermore, CNC roll grinders cannot meet the requirements for online roll profile measurement. Therefore, designing a roll profile measurement device that is easy to use and capable of online measurement is of great practical significance.

[0004] A search revealed patent CN114505356A, which discloses a roll profile measurement device and method for a strip mill. The application includes a horizontally mounted scale carriage with a fixed bracket mounted vertically at one end and a movable bracket mounted horizontally on the other end. A measuring unit is positioned between the fixed and movable brackets. The measuring unit comprises a first slider that slides on the scale carriage and a displacement measuring element positioned below the slider. A first graduated scale is positioned horizontally along the front of the scale carriage. Both the fixed bracket and the movable bracket are equipped with a second, vertically oriented graduated scale on the side closest to the roll.

[0005] For example, patent CN111922096A discloses a portable roll profile measuring instrument. The instrument in this application includes a measuring carriage, a laser ranging sensor, a data transmission device, and a data recording and processing device. The measuring instrument uses a measuring carriage mounted on the roll surface to slowly translate along the length of the roll from one end to the other. The laser ranging sensor continuously measures the distance between the laser ranging sensor and the roll surface, and transmits the distance to the data recording and processing device via the data transmission device. The data recording and processing device continuously records the measurement results and converts them into the roll diameter value in real time, thereby continuously obtaining the roll diameter, i.e., the roll profile curve.

[0006] The above applications have optimized the roller shape measurement device from different aspects, but the industry still needs more diverse designs to solve the problem that the existing roller shape measurement is relatively cumbersome and cannot be measured online. Utility Model Content

[0038] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0039] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] The present invention will be further described below in conjunction with specific embodiments.

[0041] like Figure 1 As shown, a roll shape measuring device of the present embodiment includes a saddle 1 and a measuring component 2. The saddle 1 is used to be mounted on the roll to be measured and can move along the axial direction of the roll. The measuring component 2 is provided with two groups, one on each side of the saddle 1. During operation, the distance measuring probes 24 on the measuring component 2 are respectively located on both sides of the roll to be measured and aligned with the same diameter position of the roll to be measured. As the saddle 1 moves axially, the distance measuring probe 24 can continuously or intermittently collect the diameter data of each position of the roll as the basic data for roll shape measurement. Compared with the traditional roll shape measurement method of the CNC grinder, the roll shape measuring device of the present embodiment does not require the roll to be lifted and transported, and its operation is more convenient and quick; at the same time, online measurement can also be achieved.

[0042] Specifically, refer to Figure 2 As shown, the saddle frame 1 includes a middle connecting section 11 and extension sections 12 located on both sides of the middle connecting section 11. One end of the extension section 12 is connected to the end of the middle connecting section 11, and the other end extends away from the middle connecting section 11, and a roller 13 is provided on the inner side of the extension section 12.

[0043] In other words, the extended sections 12 on both sides are arranged in an outward "X" shape, and rollers 13 are installed on opposite sides of the extended sections 12. To ensure sliding stability, multiple groups of rollers 13 can be arranged along the axial direction. When the saddle frame 1 is mounted on the roll to be tested, the rollers 13 naturally adhere to the surface of the roll under the action of gravity. Furthermore, to ensure the horizontal placement of the saddle frame 1, a level 3 can be installed on the saddle frame 1.

[0044] In this embodiment, the saddle frame 1 adopts a hollow design, which can effectively reduce the cost and the overall weight of the device and facilitate portability. Preferably, the middle connecting section 11 is a hollow design, and the level 3 is set on the outer wall of the middle connecting section 11 for easy observation.

[0045] As an implementation of the measurement component 2 in this embodiment, refer to Figure 3 As shown, the measurement assembly 2 includes a first rod 21, a second rod 22, and a distance measuring probe 24. The first rod 21 is slidably mounted on the extension section 12 and articulated with the second rod 22. The distance measuring probe 24 is located at the end of the second rod 22. In this embodiment, the sliding movement of the first rod 21 and the rotation of the second rod 22 allow the distance between the distance measuring probes 24 to be adjusted over a wide range, thereby accommodating the measurement of the roll profile of rolls of varying diameters.

[0046] It should also be noted that during measurement, the two ranging probes 24 should be positioned on opposite sides of the same circle, aligned with the ends of the same diameter. Alignment here means that the detection points of the ranging probes 24 are positioned at the ends of the same diameter. Preferably, the ranging probes 24 are positioned horizontally, i.e., the central axes of the two ranging probes 24 are positioned on an extension of the same diameter.

[0047] Specifically, if Figure 4As shown, in this embodiment, a notch 211 is formed at the end of the first rod 21, and an adjustment hole 221 is formed in the second rod 22. The first and second rods 21 and 22 can be locked together using a locking bolt 25. Of course, mounting holes for the locking bolts 25 are required on both sides of the notch 211. During assembly, the portion of the second rod 22 with the adjustment hole 221 is inserted into the notch 211 and pre-connected using the locking bolts 25. At this point, the second rod 22 and the first rod 21 are not locked together but are rotatable. Once the rotation angle of the second rod 22 is adjusted, ensuring that the distance measuring probe 24 at the end of the second rod 22 is aligned with the same diameter of the roll to be measured, the locking bolts 25 are then tightened to lock the second rod 22 to the first rod 21.

[0048] Preferably, the second rod 22 has multiple adjustment holes 221 along its length, and the locking bolts 25 engage with different adjustment holes 221 to adjust the extension length of the bottom of the second rod 22. This further expands the adjustment range of the distance between the two side distance measuring probes 24, thereby accommodating the measurement of the roll shape of more different specifications of rolls.

[0049] At the same time, reference Figure 2 As shown, a slot 121 is defined on the outer wall of the first rod 21. The first rod 21 is retained within the slot 121 and can be locked with a locking bolt 25. To prevent interference between the first rod 21 on the other side as the first rod 21 slides upward, in this embodiment, the slots 121 on the two extensions 12 are parallel and offset. That is, when the first rod 21 slides upward, the two first rods 21 are offset front-to-back and cross-sectionally, preventing interference. However, the angle between the two first rods 21 remains unchanged during the sliding process.

[0050] In this embodiment, during the rotation of the second rod 22, the distance measuring probe 24 at its end will rotate synchronously, so that the direction of the distance measuring probe 24 deviates from the diameter of the roll to be measured, thereby affecting the accuracy of the measurement result. Figure 5 As shown, in this embodiment, a rotating shaft 23 is mounted on the second rod 22, and a distance measuring probe 24 is disposed on the rotating shaft 23. Of course, the rotating shaft 23 is rotatable, thereby driving the distance measuring probe 24 to rotate so as to align with the same diameter position of the roll to be measured, thereby ensuring the accuracy of the measurement result.

[0051] Preferably, multiple sets of distance measuring probes 24 can be installed on the rotating shaft 23 along the axis of the roll to be measured, for outputting multiple sets of data regarding the diameter of the roll to be measured at the same location. Of course, a temperature measuring probe 26 can also be added to the rotating shaft 23, thereby enabling the simultaneous collection of multiple types of data in a single measurement, thereby expanding the range of measurement options and improving work efficiency. Furthermore, to facilitate observation of the horizontality of the rotating shaft 23, a level 3 can also be installed at the end of the rotating shaft 23. It should be noted that the distance measuring probes 24 and temperature measuring probes 26 in this embodiment can be purchased directly on the market. Their structures and operating principles are conventional and will not be further described.

[0052] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
