Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, and in particular to a method for measuring a wide and thick plate belt roller bearing seat. Background Art

[0002] At present, most wide and thick plate bearing seats are measured by traditional tools such as vernier calipers or outside micrometers. This method can only measure part of the bearing seat and cannot find the center axis of the bearing seat, so new technology is urgently needed.

[0003] At present, the measurement method of bearing seat is as follows:

[0004] (1) Chinese patent CN201610748522.9 discloses a method for detecting the symmetry of a hot rolling belt roller bearing seat liner. The detection method includes: when the bearing seat is in a belt roller state, the support roller is lifted and the bearing seat is suspended. Due to the large weight of the bearing seat (usually >7t / piece) and the symmetrical structure, the upper generatrix of the bearing seat, the bearing, and the support roller form a line contact, and the axis of the support roller is located on the symmetry plane of the inner hole of the bearing seat. Then the origin of the coordinate system is established on the axis of the support roller, and the bearing seat liner is detected at multiple points using a laser tracker. The symmetry value of the hot rolling belt roller bearing seat liner after assembly is analyzed. This method requires the manufacture of a dedicated support device and only uses one coordinate system establishment method. However, the service life and conditions of the bearing seats of each unit are different, and the wear of the liner plates at both ends is different, which will lead to a large error when using the middle plane to measure the symmetry of the bearing seat. This invention uses four control points, which will cause the control network accuracy to be unstable, mainly because the deviation of individual control points will cause the angle of the entire control surface to change.

[0005] (2) Chinese patent CN201610748486.6 discloses a method for detecting the symmetry of a cold-rolled bearing seat lining, which includes: when the bearing seat component is in a stationary state, the origin of the coordinate system is established on the axis of the inner hole of the bearing seat, and a laser tracker is used to perform multi-point detection, and the symmetry value of the lining after the cold-rolled bearing seat is assembled is analyzed. This method uses a laser tracker to detect the symmetry of the cold-rolled bearing seat lining, avoiding the influence of the personal skills and quality of the assembly fitter, resulting in the symmetry not meeting the design and use requirements, resulting in the formation of a cross axis of the roller system under the rolling working state, thereby affecting the quality of the cold-rolled thin plate. The symmetry of the cold-rolled bearing seat is detected by a laser tracker, with the inner hole axis as the reference, ensuring the unification of the measurement and design references and improving the detection accuracy. However, this method has the disadvantages that the bearing seat cannot be measured with a roller, and the measurement is time-consuming and laborious.

[0006] In summary, the existing bearing seat measurement method still has the disadvantages that it takes too long to measure the bearing seat and cannot meet the production requirements. In addition, the data processing method of the existing bearing seat measurement method is too simple and fails to consider various situations in actual production. It also requires the manufacture of a special V-shaped roller tool. Summary of the invention

[0007] In view of this, the present invention proposes a measurement method and a measurement system for a wide and thick plate belt roller bearing seat, which are used for measuring the belt roller bearing seat and have high measurement accuracy and are accurate and reliable.

[0013] Furthermore, the position data of the outlet operating side liner, the outlet driving side liner, the roller surface, the operating side lower bottom plate and the driving side lower bottom plate are measured at the second detection position by using a laser tracker.

[0014] Furthermore, the step of establishing different coordinate systems based on the parallelism, flatness and verticality of each lining plate and each top plate includes: judging whether the parallelism of the inlet operating side lining plate and the outlet operating side lining plate or the parallelism of the inlet transmission side lining plate and the outlet transmission side lining plate is less than a set parallelism threshold; if the parallelism of the operating side lining plate or the transmission side lining plate is less than the set parallelism threshold, then establishing coordinate system one; if the parallelism of the operating side lining plate or the transmission side lining plate is greater than the set parallelism threshold, judging the verticality and flatness of the inlet operating side lining plate and the outlet operating side lining plate and the top plate on the operating side or the inlet Whether the verticality and flatness of the transmission side lining plate and the outlet transmission side lining plate and the transmission side upper top plate meet the requirements; if the flatness of one of the lining plates on the operating side meets the requirements and the verticality of the lining plate and the operating side upper top plate meets the requirements, or the flatness of one of the lining plates on the transmission side meets the requirements and the verticality of the lining plate and the transmission side upper top plate meets the requirements, then establish coordinate system two; if the flatness of one of the lining plates on the operating side or the verticality of the lining plate and the operating side upper top plate does not meet the requirements, or the flatness of one of the lining plates on the transmission side or the verticality of the lining plate and the transmission side upper top plate does not meet the requirements, then establish coordinate system three.

[0015] Furthermore, the step of establishing the first coordinate system includes: the first element is the end point of the operating side axis or the end point of the transmission side axis; the second element is the axis; and the third element is the average plane of the operating side or the average plane of the transmission side.

[0016] Furthermore, the step of establishing the second coordinate system includes: the first element is the end point of the operating side axis or the end point of the transmission side axis; the second element is the axis; the third element is the operating side lining or the transmission side lining whose flatness and verticality meet the requirements.

It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. The embodiments described are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] Figure 1 The flowchart of the method for measuring the bearing seat of the wide and thick plate belt roller provided by the embodiment of the present invention is as follows. The method for measuring the bearing seat of the wide and thick plate belt roller is further described in detail in conjunction with the accompanying drawings.

[0029] See also Figure 1 The measurement method of the wide and thick plate belt roller bearing seat includes the following steps:

[0030] S100, arranging a bearing seat support device, wherein the bearing seat support device includes a rolling roller, an operating side support device arranged on the operating side of the rolling roller, and a driving side support device arranged on the driving side of the rolling roller.

[0031] Figure 2 is a schematic diagram of the bearing support structure. Figure 2 The bearing seat support device includes a roller 2, an operating side support device arranged on the operating side of the roller 2, and a transmission side support device arranged on the transmission side of the roller 2.

[0032] Among them, the operating side support device includes an outlet operating side lining plate 3 arranged at the outlet of the operating side of the roller 2, an inlet operating side lining plate 4 arranged at the inlet of the operating side of the roller 2, an operating side upper top plate 7 arranged at the upper part of the operating side of the roller 2, and an operating side lower bottom plate 9 arranged at the lower part of the operating side of the roller 2.

[0033] Among them, the transmission side support device includes an outlet transmission side lining plate 5 arranged at the transmission side outlet of the roller 2, an inlet transmission side lining plate 6 arranged at the transmission side inlet of the roller 2, a transmission side upper top plate 8 arranged at the upper part of the transmission side of the roller 2, and a transmission side lower bottom plate 10 arranged at the lower part of the transmission side of the roller 2.

[0034] S200, adjust the bearing seat support device so that the elevation difference between the operating side support device and the transmission side support device meets the requirements.

[0035] In this embodiment, the elevation difference between the operating side support device and the transmission side support device is set to be within 0.05mm. The support device is adjusted by a laser tracker or a precision level so that the elevation difference between the operating side support device and the transmission side support device is within 0.05mm, and the support device should be kept as far away as possible from production, crane and other vibration areas and areas with unstable air pressure and temperature. There is no need to specially make a roller placement tool for testing, and the original roller placement platform can be directly used.

[0036] S300, setting up a control pile 11 on the transmission side of the roller 2.

[0037] In this embodiment, a special control pile 11 is set up on the transmission side of the roller 2 according to the measurement needs, and the height of the special control pile 11 is preferably higher than half the height of the roller. The main purpose of establishing the control pile 11 is to set up the transmission side top control point 12-2 in the transmission side height direction to make the control network more accurate. Of course, if there is a visible layout position such as a wall column at the transmission side height position, it is not necessary to set up the special control pile 11.

[0038] S400, placing the belt roller bearing seat to be inspected on the bearing seat supporting device.

[0039] Figure 3It is the distribution diagram of the gap between the roller 2 and the bearing 18, and the bearing 18 and the bearing seat. Clean the upper surface of the support device and the bottom slide surface of the belt roller bearing seat to be tested, and place the belt roller bearing seat to be tested on the bearing seat support device. When the bearing seat is in the belt roller state, the belt roller bearing seat is lifted up by the leveled bearing seat support device. Since the bearing seat support device has been leveled, the belt roller bearing seat is in an approximately horizontal state at this time, so the axis of the roller 2, the bearing 18 and the inner hole 19 of the bearing seat is almost a straight line after being projected to the geoid 1, and the gaps between the roller 2 and the bearing 18, and between the bearing 18 and the inner hole 19 of the bearing seat are symmetrically distributed at both ends of the axis 15 of the roller 2, so the axis 15 of the roller 2 can be used as the axis of the bearing seat.

[0040] S500, a control network consisting of a plurality of control points is arranged on the operating side and the transmission side of the roller 2 respectively.

[0041] After many on-site tests, it was found that when only four control points on the same plane (ground) are used, the accuracy of the control network is very unstable. This is mainly because when individual control points are deviated, the angle of the entire control surface will change, and the stability of the control network is poor. Therefore, this embodiment adopts a control network with six control points, two of which are located in the height direction of the operating side and the transmission side, respectively.

[0042] Figure 4 Schematic diagram of the arrangement of six control points in the control network. The control points include six control points, namely the first control point 12-1, the second control point 12-2, the third control point 12-3, the fourth control point 12-4, the fifth control point 12-5 and the sixth control point 12-6; wherein the first control point 12-1 and the second control point 12-2 are respectively located in the height direction of the operating side and the transmission side.

[0043] The specific arrangement of the six control points of the control network is as follows:

[0044] Four control points are set up on the ground at the four corners of the belt roller bearing seat to be tested, namely the third control point 12-3, the fourth control point 12-4, the fifth control point 12-5 and the sixth control point 12-6; a first control point 12-1 is set up on the top of the operating side bearing seat to control the height direction accuracy of the operating side; a second control point 12-2 is set up on the top of the transmission side bearing seat, the main purpose of which is to control the height direction accuracy of the transmission side.

[0045] S600, setting a detection position 1 and a detection position 2, setting up a laser tracker at the detection position 1, and establishing a geoid.

[0046] In this embodiment, in order to establish an additional first control point 12-1 in the height direction of the operating side (the upper part of the bearing seat), two instrument installation points are set at both ends of the operating side belt roller bearing seat, namely detection position one and detection position two, to ensure that the laser tracker can simultaneously measure the coordinate data of six control points at the two instrument installation points.

[0047] First, the laser tracker is set up at the detection position 1, and the laser tracker is self-checked and calibrated to establish the geoid 1.

[0048] S700, based on the geoid 1 and the control pile 11, use a laser tracker to measure the position data of the entrance operating side liner 4, the entrance transmission side liner 6, the roller surface of the roller 2, the operating side upper top plate 7 and the transmission side upper top plate 8 at the detection position one.

[0049] S800, using a laser tracker to measure six control points at detection position one and detection position two respectively and record their coordinate values, and performing adjustment calculation on the measurement results of the six control points measured twice.

[0050] S900, based on the geoid 1 and the control pile 11, the position data of the outlet operating side liner 3, the outlet transmission side liner 5, the roller surface of the roller 2, the operating side lower bottom plate 9 and the transmission side lower bottom plate 10 are measured at the detection position 2 using a laser tracker.

[0051] S1000, calculate the parallelism, flatness and verticality of each lining plate and each top plate, establish different coordinate systems based on the parallelism, flatness and verticality of each lining plate and each top plate, and use the different coordinate systems to measure the roller bearing seat.

[0052] This embodiment adopts three coordinate system establishment methods according to different conditions such as parallelism, flatness and verticality of each liner, so that the measurement data is closer to the actual situation of the bearing seat.

[0053] Please attach Figure 5 The specific implementation of step S1000 is as follows:

[0054] (1) Determine whether the parallelism between the inlet operating side lining plate 4 and the outlet operating side lining plate 3 or the parallelism between the inlet transmission side lining plate 6 and the outlet transmission side lining plate 5 is less than a set parallelism threshold of 0.2 mm.

[0055] (2) If the parallelism of the operating side lining or the transmission side lining is less than 0.2 mm, the coordinate system 1 is established as follows:

[0056] The first element is the operating side axis end point 13 or the transmission side axis end point 14 ; the second element is the axis 15 ; and the third element is the operating side average surface 16 or the transmission side average surface 17 .

[0057] (3) If the parallelism of the operating side lining plate or the transmission side lining plate is greater than 0.2 mm, the verticality and flatness of the inlet operating side lining plate 4 and the outlet operating side lining plate 3 with the operating side upper top plate 7 or the verticality and flatness of the inlet transmission side lining plate 6 and the outlet transmission side lining plate 5 with the transmission side upper top plate 8 are determined. If the flatness of one of the operating side lining plates (the inlet operating side lining plate 4 or the outlet operating side lining plate 3) is good and the verticality of the lining plate with the operating side upper top plate is also good, or if the flatness of one of the transmission side lining plates (the inlet transmission side lining plate 6 or the outlet transmission side lining plate 5) is good and the verticality of the lining plate with the transmission side upper top plate is also good, the following method is used to establish the second coordinate system:

[0058] The first element is the operating side axis endpoint 13 or the transmission side axis endpoint 14; the second element is the axis 15; the third element is the operating side liner (inlet operating side liner 4 or outlet operating side liner 3) or the transmission side liner (inlet transmission side liner 6 or outlet transmission side liner 5) with good flatness and verticality.

[0059] (4) If the conditions in (2) and (3) are not met, coordinate system 3 is established as follows:

[0060] The first element is the operating side axis end point 13 or the transmission side axis end point 14; the second element is the axis 15; the third element is the operating side upper top plate 7 or the transmission side upper top plate 8.

[0061] The roller bearing seat is measured by using different established coordinate systems, making the measurement data closer to the actual situation of the bearing seat.

[0062] The above-mentioned measurement method of the wide and thick plate belt roller bearing seat realizes the belt roller bearing seat detection, improves the detection accuracy and efficiency of the bearing seat, can meet the requirements of the existing production mode, and does not require other auxiliary measurement tools. The measurement is high in accuracy and reliable.

[0063] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may occur depending on design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
