Description

Technical Field

[0001] This invention relates to the field of auxiliary measuring tools, and more specifically, to a quick measuring ruler for measuring the diameter of rolling mill rolls and its method of use. Background Technology

[0002] In the machining of special steel rolls, rolls vary in specifications and diameters. Measuring them using micrometers and vernier calipers is inconvenient, especially when measuring large roll diameters of 800mm-1100mm. Large vernier calipers and specialized measuring rulers are bulky, too large, and difficult to use, resulting in time-consuming, labor-intensive, and inefficient measurements. Currently, special steel roll diameters require that the upper and lower diameters of the same roll set be within 1mm. Using existing large vernier calipers or specialized measuring rulers is difficult and prone to significant measurement errors. Therefore, it is necessary to design a rapid measuring ruler for measuring large-diameter rolls to improve these shortcomings and problems. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a quick measuring ruler for measuring the diameter of rolling mill rolls and a method of using it. The quick measuring ruler has a simple structure, is lightweight, and can be quickly connected to the rolling mill roll. When used in conjunction with a conventional vernier caliper, the measurement error of the roll diameter can be controlled within 0.5mm, which meets production requirements.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A quick measuring ruler for measuring the diameter of a rolling mill roll includes two clamping components and a locking assembly. The clamping components include an integrally formed clamping straight rod and a measuring curved rod. The measuring curved rod is arc-shaped. One end of the clamping straight rod is connected to one end of the measuring curved rod. The other ends of the two clamping straight rods are hinged. The locking assembly is disposed at the hinge of the two clamping straight rods. The two measuring curved rods form a measuring structure that fits tightly against the side of the rolling mill roll. The other end of the two locking assemblies away from the corresponding clamping straight rod is the measuring end.

[0006] In one embodiment, the locking assembly includes a locking bolt and a locking nut, with a hinged through hole provided at the end of the clamping rod away from the measuring bent rod, the two hinged through holes of the clamping rod being aligned, and the locking bolt passing through the hinged through hole and connected to the locking nut.

[0007] In one embodiment, the measuring bending rod is provided with two sets of parallel auxiliary straight rods, which are respectively arranged on the two ends of the measuring bending rod and are parallel to the axis of the roll.

[0008] In one embodiment, the quick measuring ruler further includes a positioning component, and an auxiliary measuring plate is provided at the measuring end of the measuring rod, with one end of the auxiliary measuring plate hinged to the measuring end;

[0009] The positioning component includes a fixed part, a movable part, and a guide rod with a rectangular cross-section. The fixed part and the movable part are both perpendicular to the guide rod. The fixed part is located at the bottom end of the guide rod, and the movable part is sleeved on the outside of the guide rod and can move freely along the length of the guide rod. The fixed part and the movable part are parallel to each other. The fixed part has a first mating groove that fits into one of the auxiliary measuring plates, and the movable part has a second mating groove that fits into the other auxiliary measuring plate. The first mating groove and the second mating groove are parallel to each other and are both perpendicular to the guide rod.

[0010] In one embodiment, the depth of the first docking groove is the same as the depth of the second docking groove.

[0011] In one embodiment, the depth of both the first docking groove and the second docking groove is less than half the length of the auxiliary measuring plate.

[0012] A method for using a quick measuring ruler to measure the diameter of rolling mill rolls:

[0013] Loosen the locking assembly to allow the two clamping components to rotate freely. Place the measuring bent rods of the two clamping components over the roll, ensuring that the clamping rods are perpendicular to the roll axis. After both measuring bent rods are in close contact with the roll surface, re-lock the locking assembly to lock the position of the two clamping components.

[0014] At this point, there is a gap between the measuring ends of the two measuring rods. Use a vernier caliper to measure and record the minimum distance between the two measuring ends.

[0015] Loosen the locking assembly again, change the position of the two clamping members on the roll surface, and then lock the two clamping members again. Use a vernier caliper to measure and record the minimum distance between the two measuring ends.

[0016] The difference in roll diameter between the two measurement positions of the same set of rolls can be determined by the difference in the minimum distance obtained from the previous and subsequent measurements.

[0017] In one embodiment, during the process of the measuring bend contacting the roll surface, two sets of auxiliary straight rods located on the same measuring bend also contact the roll surface. Since both sets of auxiliary straight rods are parallel to the roll, the two sets of auxiliary straight rods are equivalent to clamping the roll surface, ensuring that the measuring bend remains perpendicular to the roll axis.

[0018] In one embodiment, after the two clamping components are in close contact with the roll surface, the two auxiliary measuring plates are first embedded into the first fitting groove of the fixed part and the second fitting groove of the moving part, respectively. Then, the position of the moving part is adjusted so that the auxiliary measuring plates are embedded into the first fitting groove and the second fitting groove. Since the first mating groove and the second mating groove are parallel to each other and are both perpendicular to the guide rod, the two auxiliary measuring plates are parallel to each other and are both perpendicular to the line connecting the two measuring ends. The distance between the two auxiliary measuring plates is the minimum distance between the two measuring ends. The minimum distance between the two measuring ends can be determined by measuring the distance between the two auxiliary measuring plates with a vernier caliper.

[0019] In summary, the present invention has the following beneficial effects:

[0020] This invention has a simple structure and light weight, and can be quickly connected to the rolling mill rolls. When used with conventional vernier calipers, the measurement error of the roll diameter can be controlled within 0.5mm, which meets production requirements. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] It is worth noting that the directional terms such as "up" and "down" used in this article are all relative to the perspective of the attached figures and are only for the purpose of description. They should not be interpreted as limitations on the technical solutions.

[0031] like Figure 1-3 As shown, a quick measuring ruler for measuring the diameter of a roll includes two clamping components and a locking assembly. The clamping components include an integrally formed clamping straight rod 1 and a measuring curved rod 2. The measuring curved rod 2 is arc-shaped. One end of the clamping straight rod 1 is connected to one end of the measuring curved rod 2. The other ends of the two clamping straight rods 1 are hinged. The locking assembly is located at the hinge of the two clamping straight rods 1. The two measuring curved rods 2 form a measuring structure that fits tightly against the circumferential side of the roll. The other end of the two locking assemblies away from the corresponding clamping straight rod 1 is the measuring end 3.

[0032] The measuring rod 2 of this invention is in contact with the surface of the roll, and the measuring ends 3 of the two measuring rods 2 are close together. The difference in the upper and lower roll diameters of the same set of rolls is detected by the distance between the two measuring ends 3. The method of using this invention is as follows:

[0033] Loosen the locking assembly to allow the two clamping components to rotate freely. Place the measuring bent rods 2 of the two clamping components over the roll, keeping the clamping straight rod 1 perpendicular to the axis of the roll. After both measuring bent rods 2 are in close contact with the roll surface, re-lock the locking assembly to lock the position of the two clamping components.

[0034] At this time, there is a gap between the measuring ends 3 of the two measuring rods 2. Use a vernier caliper to measure and record the minimum distance between the two measuring ends 3.

[0035] Loosen the locking assembly again, change the position of the two clamping members on the roll surface, and then lock the two clamping members again. Use a vernier caliper to measure and record the minimum distance between the two measuring ends 3.

[0036] The difference in roll diameter between the two measurement positions of the same set of rolls can be determined by the difference in the minimum distance obtained from the previous and subsequent measurements.

[0037] This invention transforms the conventional direct measurement of roller diameter into the measurement of the distance between two measuring ends, greatly reducing the measurement size and simplifying the measurement operation. Moreover, the measuring tool can be a conventional vernier caliper, resulting in high measurement efficiency.

[0038] Alternatively, the present invention can also obtain the diameter at the measuring point of the roll based on the minimum distance between the two measuring ends 3, as follows:

[0039] Loosen the locking assembly to allow the two clamping components to rotate freely. Place the measuring bent rods 2 of the two clamping components over the roll, keeping the clamping straight rod 1 perpendicular to the axis of the roll. After both measuring bent rods 2 are in close contact with the roll surface, re-lock the locking assembly to lock the position of the two clamping components. Use a vernier caliper to measure and record the minimum distance between the two measuring ends 3.

[0040] Remove the two clamping components from the roll, adjust their positions so that the minimum distance between the two measuring ends 3 is restored to the measured minimum distance value, then lock the two clamping components. The maximum distance between the measuring rods 2 is the diameter at the roll measuring point.

[0041] The method described above can also be used to measure the difference in roll diameter between different measurement points on the roll.

[0042] In this invention, the locking assembly includes a locking bolt 4 and a locking nut 5. A hinged through hole is provided at the end of the clamping straight rod 1 away from the measuring curved rod 2. The hinged through holes of the two clamping straight rods 1 are aligned. The locking bolt 4 passes through the hinged through hole and is connected to the locking nut 5. When the locking nut 5 is tightened, the positions of the two clamping components are locked. When the locking nut 5 is loosened, the two clamping components can rotate freely.

[0043] Furthermore, to ensure that the clamping component remains perpendicular to the axis of the roll, the measuring bending rod 2 is provided with two sets of parallel auxiliary straight rods 6. The two sets of auxiliary straight rods 6 are respectively located on the two ends of the measuring bending rod 2, and the auxiliary straight rods 6 are parallel to the axis of the roll. Figure 4-5 As shown.

[0044] The usage method of auxiliary rod 6 is as follows:

[0045] When the measuring bending rod 2 contacts the surface of the roll, the two sets of auxiliary straight rods 6 located on the same measuring bending rod 2 also contact the surface of the roll. Since the two sets of auxiliary straight rods 6 are parallel to the roll, the two sets of auxiliary straight rods 6 are equivalent to clamping the surface of the roll, ensuring that the measuring bending rod 2 remains perpendicular to the axis of the roll.

[0046] When the two measuring ends 3 are far apart, using vernier calipers may be inconvenient, especially when the line connecting the two measuring ends 3 passes through a roller. Therefore, this invention improves the measuring ends 3, such as... Figure 6-7 As shown, the specific structure is as follows. As not shown in 6-7, the auxiliary straight rod 6 is easy to understand. The improved quick measuring ruler can also be equipped with an auxiliary straight rod 6.

[0047] An auxiliary measuring plate 7 is provided at the measuring end 3 of the measuring rod 2, and one end of the auxiliary measuring plate 7 is hinged to the measuring end 3;

[0048] The quick measuring ruler also includes a positioning component 8, which includes a fixed part 10, a movable part 11, and a guide rod 9 with a rectangular cross-section. The fixed part 10 and the movable part 11 are both perpendicular to the guide rod 9. The fixed part 10 is located at the bottom end of the guide rod 9, and the movable part 11 is sleeved on the outside of the guide rod 9 and can move freely along the length of the guide rod 9. The fixed part 10 and the movable part 11 are parallel to each other. The fixed part 10 is provided with a first docking groove 12 that fits into one of the auxiliary measuring plates 7, and the movable part 11 is provided with a second docking groove 13 that fits into the other auxiliary measuring plate 7. The first docking groove 12 and the second docking groove 13 are parallel to each other and are both perpendicular to the guide rod 9. The depth of the first docking groove 12 is the same as the depth of the second docking groove 13, and the depth of both the first docking groove 12 and the second docking groove 13 is less than half the length of the auxiliary measuring plate 7.

[0049] It should be noted that the shapes of the first docking groove 12 and the second docking groove 13 are perfectly matched with the auxiliary measuring plate 7. After the auxiliary measuring plate 7 is fully embedded in the first docking groove 12 or the second docking groove 13, there is no gap between the auxiliary measuring plate 7 and the first docking groove 12 or the second docking groove 13.

[0050] The two parallel auxiliary measuring plates 7 actually extend the minimum distance between the two measuring ends 3 outwards in parallel. The space between the two parallel auxiliary measuring plates 7 is a space that facilitates measurement with vernier calipers. The function of the positioning component 8 is to ensure that the two auxiliary measuring plates 7 remain parallel. It is easy to understand that when the two clamping components are in close contact with the roll surface, the parallel position of the two auxiliary measuring plates 7 is not yet determined. First, the two auxiliary measuring plates 7 are respectively embedded into the first fitting groove of the fixed part 10 and the second fitting groove of the moving part 11. Then, the position of the moving part 11 is adjusted so that the auxiliary measuring plates 7 are embedded in the first fitting groove and the second fitting groove. Since the first mating groove 12 and the second mating groove 13 are parallel to each other and both are perpendicular to the guide rod 9, the two auxiliary measuring plates 7 are parallel to each other and both are perpendicular to the line connecting the two measuring ends 3. That is, the distance between the two auxiliary measuring plates 7 is the minimum distance between the two measuring ends 3. The minimum distance between the two measuring ends 3 can be determined by measuring the distance between the two auxiliary measuring plates 7 with vernier calipers.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
