Description

Technical Field

[0001] The present invention relates to the field of bevel gear inspection, and particularly to a correction method, device, computer, and storage medium for a bevel gear inspection machine. Background Art

[0002] In the inspection process of bevel gears, professional inspection machines are often used. Usually, the inspection machine includes three main shafts. One of the two horizontal main shafts provides the driving force for testing, and the other of the two horizontal main shafts is used to install the bevel gear to be tested. The main shaft on which the bevel gear is installed is driven to rotate in a plane by a vertical main shaft.

[0003] Due to the complexity in the processing and assembly processes of the inspection machine, during the installation and debugging process of the inspection machine, there will be an intersection error between the axes, and the axes cannot intersect completely, thus affecting the accuracy during the operation of the inspection machine. The intersection point of the horizontal main shafts should theoretically coincide with the central axis of the vertical main shaft, so as to complete an accurate testing process. The above limitations also imply that the positions of the central axes of the two horizontal main shafts themselves are also accurate. It is necessary to accurately measure the position offsets of the two horizontal main shafts relative to the vertical main shaft to determine the accuracy of the inspection machine itself and provide a basis for correction. However, since the alignment positions of the horizontal main shafts and the vertical main shaft are both on the extension lines and are not actual measurable points, it is very difficult to measure, and there is currently no measurement method for the structure of the inspection machine, and the effect after correction cannot be directly verified. By performing adjustments along the axial directions of the horizontal main shafts, the alignment of the two horizontal main shafts can be achieved. However, at this time, the intersection point of the two horizontal main shafts does not coincide with the axis center of the vertical main shaft. After each change in the shaft angle, a large-scale correction is required, and at the same time, the cooperation of the entire system is in a state of large deviation for a long time. Summary of the Invention

[0021] Referring to Figures 1 to 5 , in an embodiment of the present invention, a correction method for a bevel gear inspection machine, the bevel gear inspection machine includes a vertically arranged main shaft 1, a first horizontally arranged main shaft 2, and a second horizontally arranged main shaft 3 which are cooperatively arranged, and includes the following steps: S1.

Perform transverse position adjustments of Z1 and Z2 on the first horizontal main shaft 2 and the second horizontal main shaft 3 respectively in the width direction, where , .

[0022] In the prior art, the alignment positions of the horizontal main shaft and the vertical main shaft are both on the extension line, which are not actual measurable points. Therefore, it is very difficult to measure, and there is currently no measurement method for the structure of the inspection machine, and the corrected effect cannot be directly verified.

[0023] The correction method of the bevel gear inspection machine provided by the present invention. The bevel gear inspection machine includes a vertically arranged main shaft 1, a first horizontal main shaft 2 and a second horizontal main shaft 3 which are cooperatively arranged. The first horizontal main shaft 2 and the second horizontal main shaft 3 complete the rotational drive of the bevel gear. The operation of the vertical main shaft 1 changes the angle of the second horizontal main shaft 3, that is, the included angle between the first horizontal main shaft 2 and the second horizontal main shaft 3. By changing the included angle, the tests of bevel gears of different models can be completed. The correction method includes the following steps: In step S1, the inspection process is performed at different shaft included angles within the operating range. The operating range refers to the range of shaft included angles that need to be used during the application of the bevel gear inspection machine. The inspection process includes: In step S101, the ball head inspection rod 4 is installed on the second horizontal main shaft 3, and the contact type length measuring instrument 5 is installed on the first horizontal main shaft 2 and abuts against the ball head of the ball head inspection rod 4. When the test end of the contact type length measuring instrument 5 is pressed, the test value of the contact type length measuring instrument 5 changes. The model of the contact type length measuring instrument 5 is not limited, and it is specifically based on the realization of the work. One end of the ball head inspection rod 4 is a ball head with a standard spherical shape, and the detection process is completed through the standard shape of the ball head. The other end of the ball head inspection rod 4 is a clamping end. The clamping position of the ball head inspection rod 4 needs to be limited during the test process and needs to correspond to the bevel gear to play a substitution role.

[0024] In step S102, control the first horizontal main shaft 2 to rotate self, and according to the value of the contact type length measuring instrument 5, control the second horizontal main shaft 3 to displace until the value of the contact type length measuring instrument 5 remains unchanged, and record the displacement of the first horizontal main shaft 2 at this time as the first axial displacement x. If the axis of the first horizontal main shaft 2 does not coincide with the center of the ball head, then during the self-rotation process of the first horizontal main shaft 2, the degree of compression of the working end of the contact type length measuring instrument is different and the value changes. By adjusting the first horizontal main shaft 2 and cooperating with the value of the contact type length measuring instrument 5, determine the position where the axis of the first horizontal main shaft 2 coincides with the center of the ball head. At this time, the displacement of the first horizontal main shaft 2 is the first axial displacement x.

[0025] In step S103, the installation positions of the contact length measuring instrument 5 and the ball-ended probe 4 are exchanged; In step S104, the second horizontal main shaft 3 is controlled to rotate on its own axis, and according to the value of the contact length measuring instrument 5, the first horizontal main shaft 2 is controlled to displace until the value of the contact length measuring instrument 5 remains unchanged, and the displacement of the second horizontal main shaft 3 at this time is recorded as the second axis displacement y. The acquisition of the second axis displacement y refers to the foregoing description. In step S2, the current axis angle α1 is acquired, and the axis angle is adjusted to the test axis angle α2.

[0026] In step S3, the first axis displacement x1 and the second axis displacement y1 at the axis angle α1 are obtained, and the first axis displacement x2 and the second axis displacement y2 at the axis angle α2 are obtained. In step S1, the first axis displacement x and the second axis displacement y for all axis angles have been tested in advance. When the values of the axis angle α1 and the axis angle α2 are known, the relevant first axis displacement x and second axis displacement y can be known.

[0027] Through the execution of the first axis displacement x and the second axis displacement y, the alignment of the first horizontal main shaft 2 and the second horizontal main shaft 3 can be achieved, and stable operation can be realized after installing the bevel gear. However, at this time, the intersection point of the first horizontal main shaft 2 and the second horizontal main shaft 3 does not coincide with the axis of the vertical main shaft 1. After each change in the axis angle, a large-scale correction is required, and at the same time, the cooperation of the entire system is in a state of large deviation for a long time. Therefore, in the present invention, the first axis displacement x and the second axis displacement y are only executed during the inspection process, and the specific correction process is realized by adjusting the positions of the first horizontal main shaft 2 and the second horizontal main shaft 3 in the width direction; the above adjustment method is different from the method of the first axis displacement x and the second axis displacement y, and has the advantages of small adjustment and more accurate alignment of the entire system.

[0028] In step S4, the first horizontal main shaft 2 and the second horizontal main shaft 3 are respectively adjusted transversely by Z1 and Z2 in the width direction. During this process, alignment is achieved through the transverse position adjustment of the first horizontal main shaft 2 and the second horizontal main shaft 3. The above position adjustment methods can be various. For example, if the first horizontal main shaft 2 and the second horizontal main shaft 3 are fixed by bolts with adjustable positions, then precise position adjustment can be achieved through a position measuring scale.

[0029] Assuming that the axis position of the vertical main shaft 1 is C, the working points of the first horizontal main shaft 2 and the second horizontal main shaft 3 are A and B respectively, and the corrected intersection point is D. Since the distances between AD and BD (that is, the first axis displacement x and the second axis displacement y) are very small, the angles between AC (i.e., Zx) and AD and between BC (i.e., Zy) and BD can both be approximated as 90 degrees, and can be calculated through trigonometric relations Assume that the correction has been performed at the position of the shaft angle α1. Based on the shaft angle α1, further perform the position adjustments Z1 and Z2 in the width direction for the first horizontal main shaft 2 and the second horizontal main shaft 3.

[0030] , .

[0031] The specific calculation process also utilizes the calculation formula.

[0032] It should be noted that under different shaft angle conditions, the difference between Zx and Zy is not significant. However, due to the assembly and operation problems of the entire inspection machine, the correction amount can be calculated at each shaft angle, thereby making the operation process more stable and accurate.

[0033] In summary, to solve the problem that when achieving workpiece alignment through the axial coordinate adjustment of the first horizontal main shaft 2 and the second horizontal main shaft 3, the intersection point does not coincide with the axis of the vertical main shaft 1 and a large-scale correction is required every time the shaft angle changes, a specific correction process is realized through the position adjustment of the first horizontal main shaft 2 and the second horizontal main shaft 3 in the width direction based on the first shaft displacement x and the second shaft displacement y; it has the advantages of small adjustment and more accurate alignment of the entire system, and the operation process is more stable and accurate.

[0034] In one embodiment, a first linear driver and a second linear driver are respectively provided corresponding to the first horizontal main shaft 2 and the second horizontal main shaft 3. The steps of S4 include: Control the first linear driver and the second linear driver to respectively drive the first horizontal main shaft 2 and the second horizontal main shaft 3 to complete displacements of Z1 and Z2 in the width direction.

[0035] In this embodiment, the types of the first linear driver and the second linear driver can be lead screw type or linear servo drive, etc., to complete the control drive of the positions of the first horizontal main shaft 2 and the second horizontal main shaft 3 in the width direction, thereby improving the automation of the entire correction method. Taking the first horizontal main shaft 2 as an example above, the width direction of the first horizontal main shaft 2 refers to the horizontal direction perpendicular to the central axis of the first horizontal main shaft 2.

[0036] In one embodiment, after the step of S1, it includes: S105. According to the numerical magnitudes of the first shaft displacement x and the second shaft displacement y at all shaft angles within the operating range, calculate the transverse displacement values Zx and Zy that the first horizontal main shaft 2 and the second horizontal main shaft 3 respectively need to perform, and select a pair of median values from all pairs of Zx and Zy and use the corresponding shaft angle as the base shaft angle. And at the base shaft angle, adjust the positions of the first horizontal main shaft 2 and the second horizontal main shaft 3 in the width direction according to Zx and Zy to complete the correction process, where ; S106. Update all the first-axis displacements x and second-axis displacements y under all axis angle conditions.

[0037] In this embodiment, considering that the bevel gear inspection machine needs to be corrected in advance under specific axis angle conditions, in order to reduce the difficulty of the correction process for customers before testing, a setting method for the basic axis angle is provided. The adjustment process of the first-axis displacement x and the second-axis displacement y is relatively simple, and the above position process aims to provide the basic data for calculating Z1 and Z2. Therefore, their numerical values are not used as a reference. It is relatively difficult to achieve the displacement of the first transverse main shaft 2 and the second transverse main shaft 3 in the width direction. Therefore, select a pair of median values from all pairs of Zx and Zy and use the corresponding axis angle as the basic axis angle to correct the bevel gear inspection machine under the basic axis angle condition, and update all the first-axis displacements x and second-axis displacements y under all axis angle conditions. At this time, under different axis angles, the correction degree for the first transverse main shaft 2 and the second transverse main shaft 3 can be reduced. The method of selecting the axis angle based on Zx and Zy can be diverse, and an appropriate angle can be selected as the axis angle with reference to the average value or the weighted average value.

[0038] In one embodiment, a first base for bearing and a second base for bearing are respectively provided corresponding to the first transverse main shaft 2 and the second transverse main shaft 3. The first linear driver and the second linear driver respectively drive the first base and the second base to move in the width direction. In the step S105, the correction process under the basic axis angle is to adjust the positions of the first transverse main shaft 2 and the second transverse main shaft 3 on the first base and the second base respectively.

[0039] In this embodiment, a relatively convenient method is provided. Taking the first linear driver as an example, the first transverse main shaft 2 is installed on the first base, and the overall structure of the first transverse main shaft 2 and the first base is driven to move in the width direction by the first linear driver. The position of the first transverse main shaft 2 on the first base can be fixed by means of bolts or the like. The above fixing method has the advantages of reliability and simplicity. At this time, the initial driving position of the first linear driver corresponds to the basic axis angle. At other angles, the driving values executed by the first linear driver are all smaller.

[0040] In one embodiment, in the step S105, the selection rule for the basic axis angle is as follows: Obtain the sum values of Zx and Zy under each axis angle, and use the axis angle corresponding to the sum value that is closest to the average of the largest sum value and the smallest sum value as the basic axis angle.

[0041] In this embodiment, a basic axis angle is selected with reference to the average value of the maximum sum value and the small sum value, so that during the correction process, the lateral drive that the first transverse main axis 2 and the second transverse main axis 3 need to execute is minimized, and at the same time, it is the simplest and the possibility of forming an error is also the lowest.

[0042] In one embodiment, after the step of S1, it includes: S107. Receive the setting of the basic axis angle, and complete the correction process by adjusting the positions of the first transverse main axis 2 and the second transverse main axis 3 in the width direction according to Zx and Zy under the basic axis angle, where, ; S108. Update all the first axis displacements x and the second axis displacements y under all axis angle conditions.

[0043] In this embodiment, considering that the customer experiments with different models of bevel gears during the use of the bevel gear inspection machine, but there is a most common model range, so a basic axis angle is set. Then, during the use of the bevel gear inspection machine, the correction process can be corrected as much as possible. For example, the axis angle ranges required for various bevel gears that the customer needs to test are in the range of 45 degrees to 70 degrees. Then, the basic axis angle can be set to 60 degrees. After the correction is completed at 60 degrees, that is, the positions of the first transverse main axis 2 and the second transverse main axis 3 in the width direction are adjusted, and then all the first axis displacements x and the second axis displacements y under all axis angle conditions are updated to provide a reference for the subsequent process.

[0044] In one embodiment, linear grating components for detecting displacements are efficiently arranged corresponding to the widths of the first transverse main axis 2 and the second transverse main axis 3.

[0045] In this embodiment, through the operation of the linear grating components, the displacements of the first transverse main axis 2 and the second transverse main axis 3 in the width direction can be monitored, so that the working accuracies of the first linear driver and the second linear driver can be detected and analyzed. Specifically, the model of the linear grating component is not the focus.

[0046] Refer to Figure 6 Furthermore, the present invention also provides a device for operating the correction method of the above bevel gear inspection machine, including: A storage module 10 for receiving the first axis displacement x and the second axis displacement y under different axis angles within the operating range; A processing module 20 for receiving the current axis angle α1 and the tested axis angle α2; An acquisition module 30 for obtaining the first axis displacement x1 and the second axis displacement y1 under the axis angle α1 and obtaining the first axis displacement x2 and the second axis displacement y2 under the axis angle α2; A calculation module 40 for calculating the lateral position adjustments Z1 and Z2 of the first horizontal main shaft 2 and the second horizontal main shaft 3 in the width direction respectively, where, , .
