Description

Technical Field

[0001] This utility model relates to the field of corrugated roller measurement technology, and in particular to a tooling for measuring the concentricity of corrugated rollers. Background Technology

[0002] Corrugated rolls are the core components of corrugated board production equipment. The concentricity of the inner and outer diameters of the rolls with the reference axis directly affects the forming accuracy, flute consistency, and equipment operational stability of the corrugated board. Therefore, precise measurement of the concentricity is necessary during the manufacturing, inspection, and maintenance of corrugated rolls.

[0003] Currently, the measurement of the concentricity of corrugated rolls mainly relies on specialized tooling in conjunction with instruments such as dial indicators and micrometers. Traditional measuring tooling typically includes a fixed base, a clamping mechanism for holding the roll, and a measuring mechanism for mounting the measuring instruments. However, due to the diverse specifications of corrugated rolls, varying in length and diameter, existing measuring tooling is not suitable for measuring different specifications. When measuring corrugated rolls with different shapes, different measuring tooling is often required, necessitating the use of multiple sets of measuring tooling. This ultimately increases measurement costs and makes tooling storage and management inconvenient.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

A limiting wheel is rotatably mounted on the limiting bracket, and the circumferential surface of the limiting wheel abuts against the end face of the roll to be measured to axially limit the roll to be measured.

The lower end of the vertical rod is fixed to a first mounting plate. The end of the adjustable horizontal rod near the workpiece clamping mechanism is provided with a clamp for clamping instruments. The adjustable horizontal rod is mounted on the upper end of the vertical rod via the clamping component, and its position height and the extension length of the clamp from the clamping component can be adjusted via the clamping component.

Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0040] Please see Figures 1 to 4 As shown, this utility model provides a tooling for measuring the concentricity of corrugated rolls, comprising:

[0041] Base 1, with a first guide rail 11 provided on base 1 along its length;

[0042] The workpiece clamping mechanism 2 is slidably connected to the first guide rail 11 and is used to install the roller 6 whose concentricity is to be measured. The clamping length of the workpiece clamping mechanism 2 can be adaptively adjusted according to the length of the roller 6 to be measured.

[0043] The inner diameter measuring mechanism 3 is slidably connected to the first guide rail 11 and is used to install instruments for measuring the inner diameter of the roller 6. The position of the inner diameter measuring mechanism 3 can be adaptively adjusted according to the length of the roller 6 to be measured.

[0044] The outer diameter measuring mechanism 4 is slidably connected to the first guide rail 11 and is used to install instruments for measuring the outer diameter of the roller 6. The position of the outer diameter measuring mechanism 4 can be adaptively adjusted according to the length of the roller 6 to be measured.

[0045] In actual measurement, workers clamp dial indicators or micrometers, used for measuring the inner and outer diameters of workpieces, onto the inner diameter measuring mechanism 3 and the outer diameter measuring mechanism 4 respectively and calibrate them. The corrugated roller 6 to be measured is then clamped onto the workpiece clamping mechanism 2 and rotated. The inner and outer diameters of the corrugated roller 6 can then be measured using the dial indicator or micrometer, thereby calculating the concentricity of the corrugated roller 6. By setting a first guide rail 11 along the length direction on the base 1, the workpiece clamping mechanism 2, the inner diameter measuring mechanism 3, and the outer diameter measuring mechanism 4 can all slide along the guide rail. Simultaneously, the clamping length of the workpiece clamping mechanism 2 can be adjusted according to the length of the roller 6 to be measured, and the positions of the inner and outer diameter measuring mechanisms 4 can also be flexibly adjusted according to the length of the roller 6. This corrugated roll concentricity measuring fixture is suitable for measuring the concentricity of corrugated rolls 6 of various lengths and diameters. It eliminates the need for frequent fixture changes, meaning that there is no need to configure multiple sets of fixtures separately for different specifications of rolls 6. This significantly reduces the investment in purchasing fixtures, lowers measurement costs, and facilitates the storage and management of fixtures, saving space.

[0046] In this embodiment, the base 1 is a rectangular plate with supporting feet at the bottom for contact with the factory floor. There are two first guide rails 11, which are parallel to each other on both sides of the base 1 and parallel to the axis of the corrugated roller 6 to be measured when clamped. The inner diameter measuring mechanism 3, the outer diameter measuring mechanism 4, and the workpiece clamping mechanism 2 are slidably connected to the two first guide rails 11, which helps improve sliding stability. The instruments used to measure the inner and outer diameters of the corrugated roller 6 can be dial indicators or micrometers.

[0047] Please see Figures 1 to 3As shown, the workpiece clamping mechanism 2 includes two first supports 21. At least two first sliders 12 are respectively provided at the bottom of each of the two first supports 21. The first sliders 12 are slidably connected to the first guide rail 11. The two first supports 21 can slide away from or towards each other along the first guide rail 11 to adjust the clamping length. In this embodiment, four first sliders 12 are fixed to the bottom of each first support 21 by screws. The four first sliders 12 are slidably connected to the two first guide rails 11 in pairs, which helps to improve the sliding stability of the first supports 21. The two ends of the corrugated roller 6 to be measured are respectively clamped onto the two first supports 21. The two first supports 21 can slide closer or further apart along the first guide rail 11 to adjust their distance from each other, thereby adapting to clamping corrugated rollers 6 of different lengths.

[0048] Please see Figures 1 to 3 As shown, a clamping groove 22 is provided on the top of the first support 21, and the clamping groove 22 is V-shaped. In this embodiment, the clamping groove 22 is formed by a downward recess from the middle of the top of the first support 21. The two ends of the corrugated roller 6 to be measured are accommodated in the clamping groove 22. The cross-section of the clamping groove 22 is set in a V-shape to accommodate corrugated rollers 6 of different diameters. To improve the shape stability of the clamping groove 22, the bottom of the clamping groove 22 is not a sharp angle formed by the connection of the two side groove walls, but a bottom wall parallel to the bottom of the first support 21, which can prevent the two side groove walls of the clamping groove 22 from tearing each other under the gravity of the corrugated roller 6.

[0049] Please see Figures 1 to 3 As shown, each of the two first supports 21 has a plurality of rollers 23 on one side close to each other. The rollers 23 are arranged along the wall of the clamping groove 22, and the circumferential surface of the rollers 23 is higher than the wall of the clamping groove 22 so as to make rolling contact with the outer diameter of the roller 6 to be measured. In this embodiment, each first support 21 is provided with four rollers 23, which are symmetrically arranged in pairs on both sides of the clamping groove 22. The rollers 23 are rotated on the mounting shaft through bearings, and the mounting shaft is fixedly connected to the first support 21 by bolts. The circumferential surface of the rollers 23 is higher than the wall of the clamping groove 22, that is, the circumferential surface protrudes inward from the groove wall, so that the outer circumferential surface of the corrugated roller 6 to be measured contacts the circumferential surface, thereby allowing the corrugated roller 6 to be measured to rotate relative to the first support 21, realizing rotation measurement, and effectively preventing wear caused by contact between the corrugated roller 6 and the wall of the clamping groove 22.

[0050] Please see Figures 1 to 3As shown, a limiting bracket 24 is provided on the first support 21. The limiting bracket 24 and the roller 23 are arranged opposite to each other on both sides of the first support 21. A limiting wheel 25 is rotatably mounted on the limiting bracket 24. The circumferential surface of the limiting wheel 25 abuts against the end face of the roller 6 to be measured to axially limit the roller 6. In this embodiment, the limiting bracket 24 includes a fixed crossbar 26, an adjustable longitudinal bar 27, a mounting crossbar 28, and a locking block 29. One end of the fixed crossbar 26 is fixed to the outside of the first support 21 by bolts. One end of the mounting crossbar 28 is fixed to the top of the adjustable longitudinal bar 27 by bolts. The limiting wheel 25 is rotatably mounted on the other end of the mounting crossbar 28 via a mounting shaft and bearing. The limiting wheel 25 is located at the end of the mounting crossbar 28 near the first support 21. The locking block 29 consists of two separate grooved blocks. Two grooved blocks work together to clamp the fixed crossbar 26 and the adjustable longitudinal bar 27. The two grooved blocks are then locked with bolts, connecting the adjustable longitudinal bar 27 to the fixed crossbar 26. The position of the adjustable longitudinal bar 27 on the fixed crossbar 26 and the distance between the mounting crossbar 28 and the fixed crossbar 26 can be changed via the locking block 29 (i.e., the adjustable longitudinal bar 27 can move laterally along the fixed crossbar 26 or vertically along its own length). This allows the limiting wheel 25 to be adapted to limit the movement of corrugated rollers 6 of different specifications. During adjustment, the bolts of the locking block 29 must be loosened, the adjustable longitudinal bar 27 moved laterally to the designated position on the fixed crossbar 26, and the adjustable longitudinal bar 27 moved vertically to adjust its height. Finally, the bolts of the locking block 29 are tightened to fix the adjustable longitudinal bar 27. During the measurement process, the rotation of the corrugated roller 6 will cause the corrugated roller 6 to be displaced along its axial direction. The limit wheel 25 is set to roll and contact the end face of the corrugated roller 6 to achieve the purpose of limiting and to prevent wear on the end of the corrugated roller 6.

[0051] Please see Figures 1 to 2 , Figure 4 As shown, the inner diameter measuring mechanism 3 includes two second supports 31. At least two first sliders 12 are respectively provided at the bottom of each of the two second supports 31, and are slidably connected to the first guide rail 11 via the first sliders 12. The two second supports 31 are located on both sides of the workpiece clamping mechanism 2 and can be close to or far from each other. In this embodiment, the bottom of each second support 31 is fixedly connected to two first sliders 12 by bolts. The two first sliders 12 are slidably connected to two first guide rails. The position of the two second supports 31 on the first guide rail 11 and the distance between them can be adaptively adjusted according to the actual length of the corrugated roller 6 to be measured. The two second supports 31 are located on the side of the two first supports 21 that is far from each other, i.e., on the outside of the first supports 21. The distance between the second support 31 and its adjacent first support 21 can be adjusted according to actual measurement needs, so that the instrument for measuring the inner diameter can extend from both ends of the corrugated roller 6 into the inside of the roller 6 to measure the inner diameter.

[0052] Please see Figures 1 to 2 , Figure 4 As shown, a second guide rail 32 is provided on the second support 31, a second slider 33 is slidably connected to the second guide rail 32, a first mounting plate 34 is fixedly connected to the second slider 33, and an instrument bracket 35 is provided on the first mounting plate 34. The instrument bracket 35 is used to mount the instrument for measuring the inner diameter of the corrugated roller 6. In this embodiment, the second guide rail 32 is perpendicular to the first guide rail 11, the second slider 33 is fixedly connected to the bottom of the first mounting plate 34 by bolts, and the instrument bracket 35 is fixedly welded to the first mounting plate 34. By cooperating with the second guide rail 32, the second slider 33 can move radially on the corrugated roller 6 to be measured, thereby adjusting the instrument for measuring the inner diameter to a suitable position for measurement.

[0053] Please see Figures 1 to 2 , Figure 4 As shown, the instrument support 35 includes a vertical rod 36, an adjustable crossbar 37, and a clamping component 38. The lower end of the vertical rod 36 is fixed to the first mounting plate 34. The adjustable crossbar 37 has a clamp 39 for clamping instruments at one end near the workpiece clamping mechanism 2. The adjustable crossbar 37 is mounted on the upper end of the vertical rod 36 via the clamping component 38, and its position height and the extension length of the clamp 39 from the clamping component 38 can be adjusted via the clamping component 38. In this embodiment, the lower end of the vertical rod 36 is welded to the first mounting plate 34, and the clamping component 38 is locked and fixed by bolts, thereby clamping the adjustable crossbar 37 onto the vertical rod 36 with an adjustable position height. At the same time, the distance between the end of the adjustable crossbar 37 with the clamp 39 and the vertical rod 36 can be adjusted according to actual measurement needs, thereby adjusting the depth of the instruments entering the corrugated roller 6. The clamp 39 is a conventional clamp 39 used for holding dial indicators or micrometers, and is fixed to the end of the adjustable crossbar 37 by welding. During adjustment, the bolts of the clamping member 38 need to be loosened, the adjustable crossbar 37 moved to the specified height on the upright 36, and the extension length of the adjustable crossbar 37 adjusted. Then, the bolts of the clamping member 38 are tightened to fix the adjustable crossbar 37. During measurement, the instrument clamped on the clamp 39 is inserted into the corrugated roller 6 through the adjustable crossbar 37, so that the measuring part of the instrument contacts the inner surface of the roller 6 for measurement.

[0054] Furthermore, to ensure the adjustment accuracy of the instrument bracket 35, the upright 36 and the adjustable crossbar 37 are each provided with a millimeter scale with an accuracy of 0.5 mm along their respective axes. The height can be adjusted by aligning the upper edge of the clamping piece 38 with a certain scale value, and the extension length can be adjusted by aligning the edge of the clamping piece 38 near the clamp 39 with a certain scale value.

[0055] Please see Figures 1 to 2As shown, the outer diameter measuring mechanism 4 includes a third support 41. At least two first sliders 12 are disposed at the bottom of the third support 41 and are slidably connected to the first guide rail 11 via the first sliders 12. The third support 41 is located between two first supports 21. In this embodiment, there is only one third support 41. The third support 41 is fixedly connected to the two first sliders 12 by bolts. The two first sliders 12 are slidably connected to the two first guide rails 11 respectively, allowing the outer diameter measuring mechanism 4 to move according to actual measurement needs.

[0056] Please see Figures 1 to 2 As shown, a third guide rail 42 is provided on the third support 41, a third slider 43 is slidably connected to the third guide rail 42, and a second mounting plate 44 is fixedly connected to the third slider 43. The second mounting plate 44 is used to mount the instrument for measuring the outer diameter of the roller 6. In this embodiment, the third guide rail 42 is perpendicular to the first guide rail 11. The third slider 43 is fixedly connected to the bottom of the second mounting plate 44 by bolts. The instrument for measuring the outer diameter of the roller 6 can be mounted on the second mounting plate 44 via a magnetic base. By cooperating with the third guide rail 42, the third mounting plate 44 can move radially on the corrugated roller 6 to be measured, thereby adjusting the instrument for measuring the outer diameter to a suitable position for measurement, so as to adapt to corrugated rollers of different diameters.

[0057] In this embodiment, the first guide rail 11, the second guide rail 32, and the third guide rail 42 have the same cross-section, and the first slider 12, the second slider 33, and the third slider 43 have the same shape and specifications. They are all fixedly connected with stroke fixing members 5. The stroke fixing member 5 is a conventional guide rail clamping and locking structure, which includes a slide block whose cross-section is adapted to the cross-section of the slider. A locking screw with a handle is provided on one side of the slide block. The locking screw thread passes through one side wall of the slide block to abut against the side of the guide rail to achieve stroke fixing. The stroke fixing member 5 of the first slider 12 is slidably connected to the first guide rail 11 and is used to clamp the first guide rail 11 to fix the position of the first slider 12 on the first guide rail 11, thereby fixing the position of the workpiece clamping mechanism 2, the inner diameter measuring mechanism 3 and the outer diameter measuring mechanism 4 on the base 1; the stroke fixing member 5 of the second slider 33 is slidably connected to the second guide rail 32 and is used to clamp the second guide rail 32 to fix the position of the second slider 33 on the second guide rail 32, thereby fixing the position of the instrument clamped on the instrument bracket 35 on the second guide rail 32; the stroke fixing member 5 of the third slider 43 is slidably connected to the third guide rail 42 and is used to clamp the third guide rail 42 to fix the position of the third slider 43 on the third guide rail 42, thereby fixing the position of the instrument clamped on the second mounting plate 44 on the third guide rail 42.

[0058] In summary, the concentricity measuring fixture for corrugated rolls described in this utility model is suitable for measuring the concentricity of corrugated rolls 6 of various lengths and diameters. It eliminates the need for frequent fixture changes, meaning that multiple sets of fixtures do not need to be configured separately for different specifications of rolls 6. This significantly reduces the investment in purchasing fixtures, lowers measurement costs, and facilitates the storage and management of fixtures, saving space.
