Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of six-sided top press calibration, and more specifically, to a six-sided top press calibration device, a six-sided top press calibration system and a six-sided top press calibration method. Background Art
[0002] After the six-sided top press is installed, the synchronization of the six working pistons and the centering of the six carbide top hammers must be adjusted to make the carbide top hammers evenly stressed and avoid bursting under high temperature and high pressure; the method of adjusting the synchronization is to adjust the opening and closing size of the six throttle valves (needle valves), and the adjustment of the carbide top hammer is mainly to adjust the carbide top hammer to a suitable working position and adjust the six working top hammers to a mutually centered state, that is, the six top surfaces of up, down, left, right, front and back are aligned with the edges of the standard block without deviation or twisting.
[0003] An invention patent application with application publication number CN114719783A was retrieved, which discloses a device and method for measuring the end face of a top hammer of a six-sided top press; the measurement and calibration method is roughly as follows: first, the end face of the lower hammer is selected as the reference top face, (i) the vertical relationship between the left and right top hammer end faces and the reference top face (the lower top hammer end face) is measured, and when the distances to the left and right top hammer end faces measured by the first laser displacement sensor and the second displacement sensor after the height is changed are equal to the distances measured for the first time, then they are vertical; (ii) the parallelism relationship between the two end faces to be measured (the left and right top hammer end faces) is measured, and the first laser displacement sensor and the second laser displacement sensor are measured. The optical displacement sensor and the second laser displacement sensor change their lateral positions and then their heights. When the distances to the left and right top hammers measured after the height change at the other position are equal, the left and right end faces are parallel. Then, the methods in (a) and (b) are used to perform the third step; (c) measure the vertical relationship between the front and rear top hammer end faces and the lower top hammer end face; (d) measure the parallelism relationship between the two end faces to be measured (the front and rear top hammer end faces); and finally, (v) measure the parallelism relationship between the two end faces to be measured (the upper top hammer end face and the lower top hammer end face) and perform corresponding calibration, thereby completing the adjustment and calibration of the six end faces.
[0004] When calibrating the above method, when measuring the perpendicularity of the two end faces, the first laser displacement sensor and the second laser displacement sensor need to change their positions and heights at the same time. The operation is relatively cumbersome and there are many measurement steps, resulting in a long measurement calibration time and low efficiency. In addition, structures such as lead screws and slide rails are used, which will wear and produce gaps as they continue to move, thereby causing measurement errors and the measurement accuracy cannot be guaranteed. When calibrating the top hammer, not only must the end faces of adjacent top hammers be perpendicular and parallel to the end face of the relative top hammer, but the top hammer cannot have an angle, that is, it cannot be twisted. The above scheme cannot calibrate the degree of twisting of the top hammer. Summary of the invention
[0005] The present invention aims to overcome at least one defect of the above-mentioned prior art and provide a six-sided top press calibration device for solving the technical problem that when measuring the perpendicularity of two end faces, both the position and the height need to be changed, the operation is cumbersome, resulting in long measurement and calibration time and low efficiency.
[0006] The technical solution adopted by the present invention is a six-sided top press calibration device, including a basic part and a distance sensor; the basic part is an L-shaped structure, including a horizontal part and a vertical part; the distance sensor includes a first distance measuring sensor, and two of the first distance measuring sensors are arranged side by side in the middle and bottom of the vertical part respectively, the position of the first distance measuring sensor in the middle corresponds to the position of the first distance measuring sensor at the bottom, and the front surface of the vertical part is perpendicular to the bottom surface of the horizontal part.
[0007] First, a flat surface is made to fit the front face of the vertical member, and the values of four first distance measuring sensors are pre-recorded; when measuring, the bottom face of the horizontal member is made to fit the end face of a reference top hammer, and the top hammer to be measured is moved so that it is close to the front face of the vertical member and contacts the four first distance measuring sensors, and the end face of the top hammer to be measured is tilted up, down, left and right by adjustment. When the values obtained by the four first distance measuring sensors are equal to the pre-recorded values, it indicates that they have been fitted with the front face of the vertical member, that is, the end face of the top hammer to be measured is perpendicular to the bottom face of the horizontal member, that is, perpendicular to the end face of the reference top hammer. This method does not require structures such as lead screws and slide rails, and will not result in a decrease in measurement accuracy due to wear. It can effectively ensure measurement accuracy, is easy to operate, saves time, and can effectively improve calibration efficiency.
[0008] Furthermore, the distance sensor also includes a second distance measuring sensor, two of which are arranged side by side at the same height on the top of the vertical member, and when the front face of the vertical member fits with the end face of the top hammer to be measured, the two second distance measuring sensors contact an inclined surface of the top hammer to be measured. The basic member is placed on the standard sample in advance, and the two second distance measuring sensors contact the standard inclined surface at the upper end of the standard sample, and the values of the two second distance measuring sensors are recorded. When measuring, the bottom surface of the horizontal member is made to fit with the end face of the reference top hammer, and the front face of the vertical member is made to fit with the end face of the top hammer to be measured, and the two second distance measuring sensors contact the inclined surface of the top hammer to be measured. When calibrating, the top hammer to be measured is twisted counterclockwise or clockwise with the center of the top hammer to be measured as the center of the circle to twist its inclined surface. When the values measured by the two second distance measuring sensors are equal to the pre-recorded values, it means that the inclined surface of the top hammer to be measured has been calibrated.
[0009] Furthermore, the side end faces of the basic component are respectively perpendicular to the bottom face of the horizontal component and the front face of the vertical component. In this way, during calibration, two-sided positioning is performed through the bottom face of the horizontal component and the side end faces of the basic component, so that the end face of the top hammer to be measured can be perpendicular to both the bottom face of the horizontal component and the side end faces of the basic component, which is equivalent to parallel calibration of the two opposite end faces of the top hammer; the side end faces of the basic component include the side end faces of the horizontal component, the side end faces of the vertical component and the side end faces of the inclined portion.
[0010] Furthermore, it also includes a standard sample, the standard sample includes a bottom plate and a proofreading plate, the proofreading plate is fixed on the bottom plate, the proofreading plate has a standard plane perpendicular to the top surface of the bottom plate, and the top of the proofreading plate is provided with a standard inclined surface. The angle between the standard plane and the standard inclined surface at the top of the proofreading plate is 130°-133°, the top surface of the bottom plate of the standard sample is perpendicular to the standard plane, and the standard inclined surface at the top of the proofreading plate is an untwisted straightened inclined surface, so that the bottom surface of the basic part is in contact with the top surface of the bottom plate, and the front surface of the vertical part is in contact with the standard plane of the standard sample. At this time, the four first distance measuring sensors and the two second distance measuring sensors all generate values, and the values at this time are the initial reference values, which are used for subsequent adjustment of the end surface and inclined surface of the top hammer to be measured.
[0011] Furthermore, two second distance measuring sensors are arranged obliquely on the top of the vertical member, and the two second distance measuring sensors have the same inclination, and the angle between the axial direction and the horizontal direction of the second distance measuring sensor is between 40° and 43°. With such installation, when measuring the value, the second distance measuring sensor arranged obliquely is perpendicular to the inclined surface of the top hammer to be measured, which can make the sensing end of the second distance measuring sensor produce a larger change, and at the same time does not affect the tilting, twisting and other actions of the top hammer to be measured.
[0012] Furthermore, the top of the vertical member is provided with an inclined portion extending obliquely away from the horizontal member, and the second distance measuring sensor is mounted on the inclined portion. The inclined portion is used to mount the second distance measuring sensor, and the force applied to the sensing end of the second distance measuring sensor when it contacts the top hammer to be measured is more reasonable.
[0013] Furthermore, it also includes a magnet, which is arranged inside the transverse member or embedded in the bottom surface of the transverse member, and is used to fix the basic member on the end surface of the top hammer. The magnet can be a strong magnet, which can provide a larger adsorption force, prevent the basic member from shifting on the end surface of the reference top hammer, and make the measured data more accurate.
[0014] Furthermore, the sensing end of the distance sensor is a pointed end, and the distance sensor has an automatic reset function. When the sensing end of the distance sensor is a round head or a cylindrical head, the top hammer is displaced and deflected, and it is in multi-position contact or curved surface contact with the end face of the top hammer, the distance sensor data does not change significantly, and the measurement error is large. When a pointed distance sensor is used, it is in point contact with the end face of the top hammer, the distance sensor data changes more significantly, and the measurement accuracy is higher. For example, the distance sensor can be selected from the Miran KTR2 pointed spring self-recovering linear displacement sensor.
[0015] The present scheme also discloses a six-sided top press calibration system, which has the aforementioned six-sided top press calibration device, and also includes a data acquisition module and a data processing module, wherein the data sampling module is electrically connected to the distance sensor and the data processing module respectively, and the data acquisition module is used to collect and transmit the data measured by the distance sensor to the data processing module, and the data processing module can determine the direction and displacement of the top hammer to be measured according to the data measured by the distance sensor. Through the cooperation of the distance sensor, the acquisition module and the data processing module, the degree of inclination and torsion of the top hammer to be measured can be accurately known, and on this basis, the data processing module can also determine the calibration direction and displacement of the top hammer to be measured according to the measured values, so as to guide the staff to adjust the top hammer to be measured, which has a high degree of intelligence and can effectively improve the efficiency of calibrating the top hammer.
[0016] The present invention also discloses a six-sided top press machine calibration method, including the above-mentioned six-sided top press machine calibration device, including the following steps: S1. Calibrate the first distance measuring sensor and the second distance measuring sensor on the basic component with a standard sample, so that the four first distance measuring sensors and the two second distance measuring sensors obtain the values of the calibration top hammer: N1, N2, N3, N4, N5 and N6; S2, taking any top hammer as the first reference top hammer, taking any top hammer adjacent to the first reference top hammer as the first top hammer to be measured, placing the basic component on the end face of the first reference top hammer, making one edge of its bottom face parallel to one edge of the end face of the first reference top hammer, moving the first top hammer to be measured so that its end face contacts the front face of the vertical component, and when the values N1, N2, N3, N4, N5 and N6 are obtained by adjusting the four first distance measuring sensors and the two second distance measuring sensors, the calibration of the first top hammer to be measured is completed; S3, taking the adjusted first top hammer to be measured as the second reference top hammer, taking the two top hammers adjacent to the second reference top hammer and opposite to each other as the second top hammers to be measured, and calibrating the two second top hammers to be measured respectively; fitting the bottom surface of the basic component with the end surface of the first reference top hammer, fitting the side end surface of the basic component with the end surface of the second reference top hammer, moving the second top hammer to be measured so that its end surface contacts the front surface of the vertical component, and when the values N1, N2, N3, N4, N5 and N6 are obtained by adjusting the four first distance measuring sensors and the two second distance measuring sensors, the calibration of the second top hammer to be measured is completed; S4, taking any second top hammer to be measured as the third reference top hammer, taking the top hammer opposite to the second reference top hammer as the third top hammer to be measured, fitting the bottom surface of the basic component with the end surface of the first reference top hammer, fitting the side end surface of the basic component with the end surface of the third reference top hammer, moving the third top hammer to be measured so that its end surface contacts the front surface of the vertical component, and when the values N1, N2, N3, N4, N5 and N6 are obtained by adjusting the four first distance measuring sensors and the two second distance measuring sensors, the calibration of the third top hammer to be measured is completed; S5. Take the top hammer opposite to the first reference top hammer as the fourth top hammer to be measured, and fit the bottom surface and the side end surface of the basic component with the second reference top hammer, the two third reference top hammers or any two adjacent top hammer end surfaces of the third top hammers to be measured respectively, move the fourth top hammer to be measured so that its end surface contacts the front surface of the vertical component, and when the values N1, N2, N3, N4, N5 and N6 are obtained by adjusting the four first ranging sensors and the two second ranging sensors, the calibration of the fourth top hammer to be measured is completed.
[0017] This calibration method does not require any other operations. After fixing the basic parts, you can start measuring and adjusting the top hammer to perform the calibration action, which can effectively shorten the calibration time and improve the calibration efficiency. Before each calibration, the basic parts can be pre-calibrated with standard samples. In this way, it can avoid the situation where the calibration accuracy is affected by wear of the distance sensor or other changes in the basic parts structure due to use. The calibration accuracy can be ensured every time with high reliability. While calibrating the verticality and parallelism of the top hammer end face, the torsion degree of the top hammer can also be calibrated at the same time. There is no need to calibrate the torsion degree of the top hammer separately, which can further improve the calibration efficiency.
[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: first, a flat surface is attached to the front face of the vertical member, and the values of four first distance measuring sensors are pre-recorded. When measuring, the bottom face of the horizontal member is attached to the end face of a reference top hammer, and the top hammer to be measured is moved so that the top hammer to be measured is close to the front face of the vertical member and contacts the four first distance measuring sensors. The end face of the top hammer to be measured is tilted up, down, left and right by adjustment. When the values obtained by the four first distance measuring sensors are equal to the pre-recorded values, it indicates that they have been attached to the front face of the vertical member, that is, the end face of the top hammer to be measured is perpendicular to the bottom face of the horizontal member, that is, perpendicular to the end face of the reference top hammer. This method does not require structures such as lead screws and slide rails, and the measurement accuracy will not decrease with wear. The measurement accuracy can be effectively guaranteed. At the same time, the operation is simple, time is saved, and the calibration efficiency can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] The drawings of the present invention are only for illustrative purposes and should not be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; it is understandable to those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted.
[0025] like Figure 1 As shown, the present scheme discloses a six-sided top press calibration device, including a basic component 1 and a distance sensor 2; the basic component 1 is an L-shaped structure, including a horizontal component 3 and a vertical component 4; the distance sensor 2 includes a first distance measuring sensor 5, and two first distance measuring sensors 5 are arranged side by side in the middle and bottom of the vertical component 4, respectively, the position of the first distance measuring sensor 5 in the middle corresponds to the position of the first distance measuring sensor 5 at the bottom, and the front side of the vertical component 4 is perpendicular to the bottom side of the horizontal component 3; the horizontal component 3 and the vertical component 4 are integrally formed.
[0026] The bottom surface of the horizontal member 3 is a rectangle, and the side where the bottom surface of the horizontal member 3 intersects with the front surface of the vertical member 4 is one side of the rectangle. In this way, when calibrating, any side of the bottom surface of the basic member 1 is made parallel to an side of the end surface of the reference top hammer, so that the front surface of the vertical member 4 can be made perpendicular to the end surface of the adjacent top hammer, that is, the basic member 1 has the reference positioning of two vertical surfaces.
[0027] The side end surface of the basic component 1 is perpendicular to the bottom surface of the horizontal component 3 and the front surface of the vertical component 4 respectively. In this way, during calibration, the bottom surface of the horizontal component 3 and the side end surface of the basic component 1 are used for two-sided positioning, so that the end surface of the top hammer to be measured can be perpendicular to the end surfaces of the two reference top hammers at the same time.
[0028] The distance sensor 2 also includes a second distance measuring sensor 6. Two second distance measuring sensors 6 are arranged side by side at the same height on the top of the vertical member 4. When the front face of the vertical member 4 is in contact with the end face of the top hammer to be measured, the two second distance measuring sensors 6 are in contact with an inclined surface of the top hammer to be measured.
[0029] The first distance measuring sensor 5 and the second distance measuring sensor 6 are both displacement sensors. It is best to use a needle probe as the probe of the displacement sensor, which can effectively ensure the measurement accuracy. Other sensors that can measure displacement can also be used. This is a well-known technology in the field and will not be described in detail here. Corresponding holes are opened on the basic component 1, and the first distance measuring sensor 5 and the second distance measuring sensor 6 are installed on the basic component 1 through the holes.
[0030] In practice, the material and manufacturing process of the top hammer may lead to problems such as uneven grain size and structure, overburning, underburning, decarburization, carburization, holes, cracks, delamination, thermal stress, etc. Under ultra-high pressure operation, these defects will cause micro-deformation in some parts of the top hammer, causing the top hammer to twist. Therefore, when calibrating the top hammer, the torsion of the top hammer needs to be calibrated.
[0031] The two second distance measuring sensors 6 are arranged obliquely at the top of the vertical member 4, and the two second distance measuring sensors 6 have the same inclination. The angle between the axial direction and the horizontal direction of the second distance measuring sensor 6 is between 40° and 43°. When installed in this way, when measuring the value, the second distance measuring sensor 6 arranged obliquely is perpendicular to the inclined surface of the top hammer to be measured, which can make the sensing end of the second distance measuring sensor 6 produce a larger change, and at the same time does not affect the tilting, twisting and other actions of the top hammer to be measured.
[0032] The top of the vertical member 4 is provided with an inclined portion 12 which extends obliquely away from the side of the horizontal member 3, and the second distance measuring sensor 6 is installed on the inclined portion 12; the inclined portion 12 is used to install the second distance measuring sensor 6, and the force applied to the sensing end of the second distance measuring sensor 6 is more reasonable when it contacts the top hammer to be measured.
[0033] The material strength of basic part 1 is not less than 200N / mm 2 Under this strength, the basic component 1 will not be deformed during measurement, and the four first distance measuring sensors 5 and the two second distance measuring sensors 6 can obtain accurate values with higher accuracy.
[0034] like Figure 2 As shown, it also includes a magnet 13, which is arranged inside the horizontal member 3 or embedded in the bottom surface of the horizontal member 3, and is used to fix the basic member 1 on the end surface of the top hammer; the magnet 13 can be a strong magnetic magnet, such as a neodymium magnet, which can provide a larger adsorption force and prevent the basic member 1 from shifting on the end surface of the reference top hammer. Four magnets 13 are correspondingly arranged at the four corners of the bottom surface of the horizontal member 3.
[0035] like Figure 3As shown, it also includes a standard sample 7, which includes a base plate 8 and a calibration plate 9. The calibration plate 9 is fixed on the base plate 8. The calibration plate 9 has a standard plane 10 perpendicular to the top surface of the base plate 8, and a standard inclined surface 11 is provided on the top of the calibration plate 9; the angle between the standard plane 10 and the standard inclined surface 11 on the top of the calibration plate 9 is 130°-133°, the top surface of the base plate 8 of the standard sample 7 is perpendicular to the standard plane 10, and the standard inclined surface 11 on the top of the calibration plate 9 is an untwisted and straightened inclined surface.
[0036] The present scheme also discloses a six-sided top press calibration system, which has the aforementioned six-sided top press calibration device, and also includes a data acquisition module and a data processing module. The data acquisition module is used to collect and transmit the data measured by the distance sensor 2 to the data processing module. The data processing module can determine the direction and displacement of the top hammer to be measured according to the data measured by the distance sensor 2. Through the cooperation of the distance sensor 2, the acquisition module and the data processing module, the degree of inclination and the degree of torsion of the top hammer to be measured can be accurately known. On this basis, the data processing module can also determine the calibration direction and displacement of the top hammer to be measured according to the measured values, so as to guide the staff to adjust the top hammer to be measured. It has a high degree of intelligence and can effectively improve the efficiency of calibrating the top hammer.
[0037] The data processing module uses a computer in the prior art, and the data acquisition module can select a data acquisition-related module in the prior art according to actual conditions; the computer processes the data to obtain the positional relationship between two adjacent top hammers, that is, whether the position of the top hammer is correct and how much the position differs. These deviations can be expressed by data through computer processing, and the measurement accuracy can reach 0.001 mm; the position data of the sensing ends of the four first distance measuring sensors 5 and the two second distance measuring sensors 6 are transmitted to the computer through the data acquisition module, and the computer processes the data. For example, the stroke of the first distance measuring sensor 5 or the two second distance measuring sensors 6 is 10 mm, the resolution of the data acquisition module is one-eight thousandth, and the value transmitted to the computer by the data acquisition module is A. Then the computer can use the formula A÷8000×10, which is the position data of the sensor sensing end. The position data of the sensing ends of the four first distance measuring sensors 5 and the two second distance measuring sensors 6 can accurately determine the direction and torsion degree of the top hammer to be measured that need to be adjusted.
[0038] The present invention also discloses a six-sided top press machine calibration method, including the above-mentioned six-sided top press machine calibration device, including the following steps: S1, calibrating the first distance measuring sensor 5 and the second distance measuring sensor 6 on the basic component 1 with a standard sample 7, so that the four first distance measuring sensors 5 and the two second distance measuring sensors 6 obtain the values of the calibration top hammer: N1, N2, N3, N4, N5 and N6; Specifically, the basic component 1 is placed on the bottom plate 8, so that the front side of the vertical component 4 is in contact with the standard plane 10 of the calibration plate 9. At this time, the four first distance measuring sensors 5 obtain four reference values N1, N2, N3 and N4; at the same time, the two second distance measuring sensors 6 contact the standard inclined surface 11 at the top of the calibration plate 9, and obtain the other two reference values N5 and N6. S2. Take any top hammer as the first reference top hammer, take any top hammer adjacent to the first reference top hammer as the first top hammer to be measured, place the basic component 1 on the end face of the first reference top hammer, make one edge of its bottom face parallel to one edge of the end face of the first reference top hammer, move the first top hammer to be measured so that its end face contacts the front face of the vertical component 4, and when the values N1, N2, N3, N4, N5 and N6 are obtained by adjusting the four first distance measuring sensors 5 and the two second distance measuring sensors 6, the calibration of the first top hammer to be measured is completed; S3, taking the adjusted first top hammer to be measured as the second reference top hammer, taking the two top hammers adjacent to and opposite to the second reference top hammer as the second top hammers to be measured, and calibrating the two second top hammers to be measured respectively; fitting the bottom surface of the basic component 1 with the end surface of the first reference top hammer, fitting the side end surface of the basic component 1 with the end surface of the second reference top hammer, moving the second top hammer to be measured so that its end surface contacts the front surface of the vertical component 4, and when the values N1, N2, N3, N4, N5 and N6 are obtained by adjusting the four first distance measuring sensors 5 and the two second distance measuring sensors 6, the calibration of the second top hammer to be measured is completed; S4, taking any second top hammer to be measured as the third reference top hammer, taking the top hammer opposite to the second reference top hammer as the third top hammer to be measured, fitting the bottom surface of the basic component 1 with the end surface of the first reference top hammer, fitting the side end surface of the basic component 1 with the end surface of the third reference top hammer, moving the third top hammer to be measured so that its end surface contacts the front surface of the vertical component 4, and when the values N1, N2, N3, N4, N5 and N6 are obtained by adjusting the four first distance measuring sensors 5 and the two second distance measuring sensors 6, the calibration of the third top hammer to be measured is completed; S5. Take the top hammer opposite to the first reference top hammer as the fourth top hammer to be measured, and fit the bottom surface of the basic component 1 and the side end surface of the basic component 1 with the second reference top hammer, the two third reference top hammers or any two adjacent top hammer end surfaces of the third top hammers to be measured respectively, and move the fourth top hammer to be measured so that its end surface contacts the front surface of the vertical component 4. When the four first distance measuring sensors 5 and the two second distance measuring sensors 6 are adjusted to obtain values of N1, N2, N3, N4, N5 and N6, the calibration of the fourth top hammer to be measured is completed, that is, the adjustment of the six top hammers is completed.
[0039] Specifically, when adjusting the top hammers to be tested (i.e., the first top hammer to be tested, the second top hammer to be tested, the third top hammer to be tested, and the fourth top hammer to be tested), the top hammer to be tested is moved so that its end face contacts with the four first ranging sensors 5, and the four first ranging sensors 5 obtain four measurement values of M1, M2, M3, and M4. At the same time, its inclined surface contacts with the two second ranging sensors 6, and the two second ranging sensors 6 obtain two values of M5 and M6.
[0040] When adjusting, first adjust the inclination of the top hammer to be measured until M1-N1, M2-N2, M3-N3, and M4-N4 are all equal to 0; then adjust the torsion degree of the second reference top hammer until M5-N5 and M6-N6 are all equal to 0, and the calibration of the top hammer to be measured is completed.
[0041] In general, the lower top hammer is usually used as the first reference top hammer, and the rear top hammer is calibrated first. Then the rear top hammer is used as the second reference top hammer, and the left and right top hammers are calibrated by the lower and rear top hammers. After that, the front top hammer is calibrated with the lower and left top hammers (or right top hammers). After the calibration is completed, the upper top hammer is calibrated with the rear and left top hammers (or right top hammers) as the reference top hammers, and the calibration of the six top hammers can be completed.
