Abstract
Description
Technical Field
[0001] This application relates to the field of cold shear machine technology, and more particularly to a measuring device for the shear blade holder of a cold shear machine. Background Technology
[0002] Cold shearing machines are mechanical devices frequently used in the metallurgical industry to cut the ends, tails, or lengths of rolled products. The cold shearing blade holder body is the core component of the cold shearing equipment, and its accuracy directly affects the shearing quality, equipment lifespan, and production efficiency. Due to long-term exposure to high impact loads and friction, the blade holder body may deform, wear, or experience centering deviations. Therefore, it is necessary to inspect the working dimensions of the blade holder body and its mounting table to facilitate adjustment. In existing technologies, laser alignment instruments or optical three-dimensional scanning methods are commonly used for measurement.
[0003] However, when using a laser alignment instrument for measurement, common industrial pollutants such as dust, oil mist, and steam can scatter or absorb the laser light, leading to signal attenuation or distortion. For example, the high dust environment in the cold shearing area of a steel plant may increase the laser measurement error by 0.02~0.05mm. Temperature fluctuations (such as ±10℃) can cause thermal expansion of the laser, affecting the stability of the optical path; equipment vibration (such as impact from a shearing machine) may cause the laser transmitter / receiver to shift.
[0004] When using optical scanning for measurement, interference from ambient light is a concern. Strong light (such as sunlight or welding arc light) can affect the projection of structured light or laser, leading to missing point cloud data or increased noise. Vibration sensitivity is also a factor; if the equipment or the object being measured vibrates during scanning (such as during workshop equipment operation), it can cause point cloud misalignment or blurring. Dust and oil contamination can also affect the measurement; metal shavings and oil mist often accumulate around cold shearing equipment, potentially adhering to the scanning surface and causing inaccurate measurement results.
[0005] Therefore, there is an urgent need for a measuring device for the blade holder of a cold shear machine to solve the above problems. Utility Model Content

[0017] The fixing sleeve is vertically disposed at the end of the measuring frame away from the rotating block, and the centerline of its axial length direction is on the same horizontal plane as the centerline of the working area of the mounting table and the tool holder body.
[0018] The two gauge blocks are slidably disposed inside the fixed sleeve.

[0032] Combination Figures 1-3As shown, a measuring device for a shear blade holder of a cold shearing machine includes a support base 10, a support rod 11, a sliding sleeve 12, a rotating block 13, a measuring frame 15, and a measuring component 20. The support base 10, with a semi-enclosed structure, is threadedly connected to a mounting table 1. The open area of the support base 10 faces the working area of the mounting table 1 and the blade holder body 2, and the open area of the support base 10 is adapted to the working area of the mounting table 1 and the blade holder body 2. The support rod 11 is disposed within the enclosed area of the support base 10, and the axial length direction of the support rod 11 is consistent with the height direction of the working area of the mounting table 1 and the blade holder body 2. The sliding sleeve 12 is threadedly connected to the support rod 11. The peripheral portion of the sliding sleeve 12 is movable up and down along the axial length of the support rod 11; the rotating block 13 is rotatably disposed on the peripheral portion of the sliding sleeve 12 and is rotatable along the radial direction of the sliding sleeve 12; one end of the measuring frame 15 is fixedly disposed on the peripheral portion of the rotating block 13, and the other end extends horizontally into the working area of the mounting table 1 and the tool holder body 2; the measuring element 20 is disposed at the end of the measuring frame 15 away from the rotating block 13, and the working end face of the measuring element 20 can move closer to or away from the two end faces in the height direction of the working area of the mounting table 1 and the tool holder body 2, and the initial position of the measuring element 20 is consistent with the center line of the working area of the mounting table 1 and the tool holder body 2.
[0033] In the above scheme, the semi-enclosed support base 10 is fixed to the mounting table 1 by a threaded connection, with the open area facing the tool holder body 2 and the working area of the table, ensuring that the measurement path is unobstructed. The opening size of the support base 10 matches the working area, ensuring a stable mounting reference for the entire measuring device. The axial direction of the support rod 11 is consistent with the height direction of the working area, and the sliding sleeve 12 moves up and down along the support rod 11 through a threaded connection to achieve coarse positioning in the vertical direction (Z-axis). The threaded adjustment provides high-precision linear displacement to adapt to the size measurement needs of the tool holder body 2 or table at different heights. The rotating block 13 is installed around the sliding sleeve 12 by a bearing or bushing and can rotate freely in the radial (horizontal) direction of the sliding sleeve 12, allowing the measuring frame 15 to cover any horizontal position in the working area to adapt to different measurement needs. One end of the measuring frame 15 is fixed to the rotating block 13, and the other end extends horizontally to the working area, ensuring that the working end face of the measuring part 20 is vertically aligned with the surface of the tool holder body 2 / table. The working end face of the measuring part 20 can be close to or far away from the two end faces of the tool holder body 2 / table along the height direction to realize the detection of vertical dimensional deviation (such as the centering deviation of the tool holder body 2 and the amount of wear).
[0034] This application achieves precise positioning of the measuring device in three-dimensional space through the vertical movement of the sliding sleeve 12 and the radial rotation of the rotating block 13. It abandons laser / optical measurement methods and, through the combined design of the support base 10, support rod 11, sliding sleeve 12, rotating block 13, measuring frame 15, and measuring component 20, achieves multi-dimensional, high-precision measurement of the working area of the tool holder body 2 and the mounting table 1. This effectively reduces measurement errors, ensures the authenticity and reliability of measurement results, and facilitates the assembly of the measuring device for measurement operations. The initial position of the measuring component 20 is aligned with the centerline of the working area. High-precision dimensional detection is achieved by finely adjusting the working end face of the measuring component 20 to be closer to or further away from the two end faces in the height direction of the working area of the tool holder body 2 / mount. The initial position of the measuring component 20 aligned with the centerline of the working area ensures the accuracy of the measurement reference.
[0035] The measuring frame 15 has a U-shaped structure. The inner wall of the measuring frame 15 abuts against the circumferential surface of the measuring component 20, and the outer wall of the measuring frame 15 is fixedly connected to the end face of the rotating block 13 away from the support base 10.
[0036] In the above scheme, the inner wall of the middle part of the measuring frame 15 contacts the circumferential surface of the measuring part 20, restricting the radial offset of the measuring part 20 and ensuring its accurate axial (vertical) movement, thus avoiding errors caused by the shaking of the measuring part 20 during measurement. The outer wall of the measuring frame 15 is rigidly connected to the end face of the rotating block 13, so that the measuring frame 15 rotates or moves synchronously with the rotating block 13, thereby accurately positioning the measuring part 20 to the target measurement point in the working area.
[0037] A telescopic member 14, consisting of multiple segmented rings connected in series, is fixedly provided between the outer wall of the measuring frame 15 and the corresponding end face of the rotating block 13, with the two ends of adjacent segmented rings being interference-fitted.
[0038] In the above scheme, the telescopic component 14 is composed of multiple segmented rings connected in series to form a telescopic mechanical structure. When the rotating block 13 rotates or the sliding sleeve 12 moves, the telescopic component 14 compensates for the slight displacement deviation of the measuring frame 15 through axial telescopic expansion, ensuring that the measuring component 20 always maintains precise alignment with the tool holder body 2 / table working area. The elastic properties of the telescopic component 14 can absorb equipment vibration or impact force during the measurement process, preventing the measuring component 20 from shifting due to vibration and improving the stability of the measurement.
[0039] The measuring component 20 includes a fixed sleeve 21, two measuring blocks 22, and two transmission rods 23. The fixed sleeve 21 is vertically disposed at the end of the measuring frame 15 away from the rotating block 13, and its centerline along the axial length is on the same horizontal plane as the centerline of the working area of the mounting table 1 and the tool holder body 2. The two measuring blocks 22 are slidably disposed inside the fixed sleeve 21. The adjacent ends of the two measuring blocks 22 are on the same horizontal plane as the centerline along the axial length of the fixed sleeve 21, and the opposite ends of the two measuring blocks 22 are flush with the two end faces of the fixed sleeve 21. One end face of each of the two measuring blocks 22 is flush with the inner wall of the fixed sleeve 21, and the opposite end faces face the working area of the mounting table 1 and the tool holder body 2. The two transmission rods 23 are horizontally disposed at both ends of the fixed sleeve 21, and the circumferential surfaces of the two transmission rods 23 mesh with the corresponding end faces of the measuring blocks 22 near the inner wall of the fixed sleeve 21.
[0040] In the above scheme, the fixed sleeve 21 is vertically installed at the end of the measuring frame 15 away from the rotating block 13, with its centerline along its axial length aligned with the centerline of the working area of the mounting table 1 and the tool holder body 2, ensuring the accuracy of the measurement reference. Two gauge blocks 22 are symmetrically slidably installed inside the fixed sleeve 21, with their adjacent end faces at the same horizontal plane as the centerline of the fixed sleeve 21, and their opposite end faces flush with both end faces of the fixed sleeve 21. One end face of the gauge block 22 contacts the inner wall of the fixed sleeve 21, while the other end face faces the working area, forming a retractable measuring head. Two transmission rods 23 are horizontally installed at both ends of the fixed sleeve 21, with their circumferential surfaces meshing with the corresponding end faces of the gauge blocks 22 near the inner wall, enabling synchronous or independent extension and retraction of the gauge blocks 22. The end of the gauge block 22 facing away from the fixed sleeve 21 is the working end face, which directly contacts the surface of the tool holder body 2 / mount, and dimensional measurement is achieved through the extension and retraction of the gauge blocks 22. The adjacent end face of gauge block 22 is aligned with the center line of fixed sleeve 21, serving as a zero-point or median reference for measurement. The displacement of gauge block 22 is adjusted by transmission rod 23 to achieve accurate measurement of the working area size.
[0041] One end of each of the two transmission rods 23 is fixedly provided with a limiting pin 24 along its radial direction, and the circumferential surface of the limiting pin 24 slides in contact with the circumferential surface of the fixed sleeve 21.
[0042] In the above scheme, the axial length direction of the limiting pin 24 is perpendicular to the radial direction of the corresponding transmission rod 23. When the operator rotates the transmission rod 23, the limiting pin can prevent the transmission rod from disengaging from the fixed sleeve 21, thereby ensuring the smoothness of the gear meshing transmission and improving the accuracy of the measurement results.
[0043] The gauge block 22 has graduations marked at equal intervals from top to bottom along its height direction on one end face near the working area of the mounting table 1 and the tool holder body 2.
[0044] In the above scheme, when the transmission rod 23 drives the gauge block 22 to slide axially along the fixed sleeve 21, the distance between the end face of the gauge block 22 and the surface of the working area changes. This distance value can be directly read through the scale, simplifying the measurement process. The evenly spaced scale markings ensure a linear relationship in the readings, facilitating rapid calculation of displacement. The adjacent end face of the gauge block 22 is aligned with the centerline of the fixed sleeve 21, serving as the zero-point reference for measurement. When the end face of the gauge block 22 is flush with the end face of the fixed sleeve 21, the scale reading is zero; when the gauge block 22 extends outwards, the scale reading is the displacement. Furthermore, the two gauge blocks 22 can extend to both sides of the working area. By comparing the scale readings of the two gauge blocks 22, the symmetry deviation or wear of the working area can be calculated, facilitating the detection of offset or uneven wear in the working area and improving the accuracy of fault diagnosis.
[0045] In practice, the gauge block 22 in this application is a cylindrical or rectangular body with a measurement accuracy of 0.02 mm.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
