Description

Technical Field

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

[0002] Bevel gear inspection often requires specialized testing machines. These machines typically consist of three main shafts: one of the two horizontal main shafts provides the driving force for testing, the other of the two horizontal main shafts is used to mount the bevel gear to be tested, and a vertical main shaft drives the main shaft to rotate in a plane.

[0003] Due to the complexity of the inspection machine's machining and assembly processes, errors in intersecting axes can occur during installation and commissioning, affecting the machine's accuracy. The intersection of the transverse spindles should theoretically coincide with the centerline of the vertical spindles to ensure accurate testing. This limitation implicitly requires the accurate positioning of the centerlines of the two transverse spindles. Accurately measuring the offset of the two transverse spindles relative to the vertical spindle is necessary to assess the accuracy of the inspection machine and provide a basis for corrections. However, since the alignment points of the transverse and vertical spindles are located on their extensions, not physically measurable points, measurement is challenging. Currently, there are no measurement methods specific to the inspection machine's structure, and the correction results cannot be directly verified. While axial adjustment of the transverse spindles can achieve alignment, the intersection of the two transverse spindles does not coincide with the axis of the vertical spindle. Each change in the axis angle requires significant correction, resulting in significant system misalignment. Summary of the Invention

[0004] The main purpose of the present invention is to provide a correction method, device, computer and storage medium for a bevel gear testing machine, aiming to solve the problem that the two transverse main shafts are aligned by adjusting the axial direction of the transverse main shaft, but the intersection of the two transverse main shafts does not coincide with the axis of the vertical main shaft. Each time the shaft angle changes, a large-scale correction is required, and the coordination of the entire system is in a state of large deviation for a long time.

[0046] Reference Figures 1 to 5 In one embodiment of the present invention, a correction method for a bevel gear testing machine is provided, wherein the bevel gear testing machine includes a vertical main shaft 1, a first transverse main shaft 2, and a second transverse main shaft 3 that are cooperatively arranged, and includes the following steps:

[0047] S1. Perform the inspection process at different shaft angles within the operating range, including:

[0048] S101, installing the ball head test rod 4 on the second transverse main shaft 3, and installing the contact length measuring instrument 5 on the first transverse main shaft 2 so that it contacts the ball head of the ball head test rod 4;

[0049] S102, controlling the rotation of the first transverse main axis 2, and controlling the displacement of the second transverse main axis 3 according to the value of the contact length measuring instrument 5 until the value of the contact length measuring instrument 5 remains unchanged, and recording the displacement of the first transverse main axis 2 at this time as the first axis displacement x;

[0054] S4, adjusting the transverse positions of the first transverse main axis 2 and the second transverse main axis 3 in the width direction by Z1 and Z2 respectively, wherein:

[0055] , .

[0056] In the existing technology, the alignment positions of the horizontal main axis and the vertical main axis are all on the extension line, which is not an actual measurable point. Therefore, it is very difficult to measure. There is currently no measurement method for the inspection machine structure, and the effect after correction cannot be directly verified.

[0057] The present invention provides a correction method for a bevel gear testing machine. The bevel gear testing machine includes a coordinated vertical spindle 1, a first transverse spindle 2, and a second transverse spindle 3. The first and second transverse spindles 2 and 3 drive the bevel gears. The operation of the vertical spindle 1 changes the angle of the second transverse spindle 3, that is, the angle between the first and second transverse spindles 2 and 3. By changing the angle, different models of bevel gears can be tested. The correction method includes the following steps:

[0058] In step S1, the inspection process is performed at different shaft angles within the operating range. The operating range refers to the shaft angle range that needs to be used in the application of the bevel gear inspection machine. The inspection process includes:

[0059] In step S101, the ball head test rod 4 is installed on the second transverse main shaft 3, and the contact length measuring instrument 5 is installed on the first transverse main shaft 2 and contacts the ball head of the ball head test rod 4. When the test end of the contact length measuring instrument 5 is pressed, the test value of the contact length measuring instrument 5 changes. The model of the contact length measuring instrument 5 is not limited, and the specific work is subject to implementation. One end of the ball head test rod 4 is a standard spherical ball head, and the detection process is completed by the standard shape of the ball head. The other end of the ball head test rod 4 is a clamping end. The clamping position of the ball head test rod 4 during the test process needs to be limited, and it needs to correspond to the bevel gear to play a replacement role.

[0060] In step S102, the first transverse main axis 2 is controlled to rotate, and based on the value of the contact length measuring instrument 5, the second transverse main axis 3 is controlled to move until the value of the contact length measuring instrument 5 remains unchanged. The displacement of the first transverse main axis 2 at this point is recorded as the first axis displacement x. If the axis of the first transverse main axis 2 does not coincide with the center of the ball head, the working end of the contact length measuring instrument will be compressed to varying degrees during the rotation of the first transverse main axis 2, causing the value to change. By adjusting the first transverse main axis 2 and combining it with the value of the contact length measuring instrument 5, the position at which the axis of the first transverse main axis 2 coincides with the center of the ball head is determined. At this point, the displacement of the first transverse main axis 2 is recorded as the first axis displacement x.

[0061] In step S103, the installation positions of the contact length measuring instrument 5 and the ball-end probe 4 are exchanged;

[0062] In step S104, the second transverse main axis 3 is controlled to rotate, and based on the value of the contact length measuring instrument 5, the first transverse main axis 2 is controlled to move until the value of the contact length measuring instrument 5 remains unchanged. The displacement of the second transverse main axis 3 at this time is recorded as the second axis displacement y. The second axis displacement y is obtained as described above. In step S2, the current axis angle α1 is obtained and adjusted to the tested axis angle α2.

[0063] In step S3, the first axis displacement x1 and the second axis displacement y1 are obtained at the axis angle α1, and the first axis displacement x2 and the second axis displacement y2 are obtained at the axis angle α2. In step S1, the first axis displacement x and the second axis displacement y for all axis angles have been tested in advance. Once the values ​​of the axis angle α1 and the axis angle α2 are known, the relevant first axis displacement x and the second axis displacement y can be determined.

[0064] By performing the first axis displacement x and the second axis displacement y, the first transverse main axis 2 and the second transverse main axis 3 can be aligned, and stable operation can be achieved after the bevel gear is installed. However, at this time, the intersection of the first transverse main axis 2 and the second transverse main axis 3 does not coincide with the axis center of the vertical main axis 1. Each time the axis angle changes, a large-scale correction is required, and the coordination of the entire system is also 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 performed during the inspection process. The specific correction process is achieved by adjusting the position of the first transverse main axis 2 and the second transverse main axis 3 in the width direction. The above adjustment method is different from the first axis displacement x and the second axis displacement y method, and has the advantages of small adjustment and more accurate alignment of the entire system.

[0065] In step S4, the first and second transverse main axes 2 and 3 are adjusted transversely in the width direction at Z1 and Z2, respectively. During this process, alignment is achieved by adjusting the transverse positions of the first and second transverse main axes 2 and 3. This position adjustment can be performed in a variety of ways. For example, if the first and second transverse main axes 2 and 3 are secured with adjustable bolts, precise position adjustment can be achieved using a position gauge.

[0066] Assuming that the axis position of the vertical main axis 1 is C, the working points of the first transverse main axis 2 and the second transverse main axis 3 are A and B respectively, and the corrected intersection point is D, since the distance between AD and BD (that is, the displacement of the first axis x and the displacement of the second axis y) is very small, the angle between AC (i.e. Zx) and AD and the angle between BC (i.e. Zy) and BD can be approximately 90 degrees. Through trigonometric relationships, it can be calculated that It is known that the position of the axis angle α1 has been corrected. Based on the axis angle α1, the position adjustments Z1 and Z2 in the width direction are performed on the first transverse main axis 2 and the second transverse main axis 3.

[0067] , .

[0068] The specific calculation process also uses Just use the calculation formula.

[0069] It should be noted that the difference between Zx and Zy is not large under different axis angle conditions. However, due to the assembly and operation of the entire inspection machine, the correction amount can be calculated at each axis angle, making the operation process more stable and accurate.

[0070] In summary, in order to solve the problem that when the working alignment is achieved by adjusting the axial coordinates of the first transverse main axis 2 and the second transverse main axis 3, the intersection does not coincide with the axis center of the vertical main axis 1, and a large-scale correction is required each time the axis angle changes, the specific correction process is achieved by adjusting the positions of the first transverse main axis 2 and the second transverse main axis 3 in the width direction based on the first axis displacement x and the second axis 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 precise.

[0071] In one embodiment, a first linear drive and a second linear drive are respectively provided corresponding to the first transverse main axis 2 and the second transverse main axis 3, and the step S4 includes:

[0072] The first linear drive and the second linear drive are controlled to drive the first transverse main axis 2 and the second transverse main axis 3 to complete displacements of Z1 and Z2 in the width direction respectively.

[0073] In this embodiment, the first and second linear actuators can be screw-type or linear servo drives, etc., to control the widthwise position of the first and second transverse spindles 2 and 3, thereby enhancing the automation of the entire correction method. Taking the first transverse spindle 2 as an example, the widthwise direction of the first transverse spindle 2 refers to the horizontal direction that is perpendicular to the central axis of the first transverse spindle 2.

[0074] In one embodiment, after step S1, the method includes:

[0075] S105. Calculate the required transverse displacement values ​​Zx and Zy for the first transverse main axis 2 and the second transverse main axis 3, respectively, based on the values ​​of the first axis displacement x and the second axis displacement y at all axis angles within the operating range. Select a median value among all Zx and Zy pairs and use the corresponding axis angle as the base axis angle. Adjust 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 at the base axis angle to complete the correction process. ;

[0076] S106 , updating the first axis displacement x and the second axis displacement y under all axis angle conditions.

[0077] In this embodiment, considering that the bevel gear testing machine requires pre-calibration under specific shaft angle conditions, a method for setting the base shaft angle is provided to reduce the difficulty of the pre-test calibration process for customers. The adjustment process for the first shaft displacement x and the second shaft displacement y is relatively simple, and the above positioning process is intended to provide basic data for calculating Z1 and Z2. Therefore, their numerical values ​​are not used as a reference. The widthwise displacement of the first and second transverse principal axes 2 and 3 is more difficult to achieve. Therefore, a median pair of values ​​is selected from all Zx and Zy pairs and the corresponding shaft angle is used as the base shaft angle. The bevel gear testing machine is calibrated under the base shaft angle condition, and the first shaft displacement x and second shaft displacement y are updated for all shaft angle conditions. At this point, the degree of correction for the first and second transverse principal axes 2 and 3 can be reduced at different shaft angles. Various methods can be used to select the shaft angle based on Zx and Zy, with the average or weighted average being used as a reference to select the appropriate angle as the shaft angle.

[0078] In one embodiment, a first base and a second base are provided for supporting the first transverse main axis 2 and the second transverse main axis 3, respectively, and a first linear drive and a second linear drive drive the first base and the second base to move in the width direction, respectively. In the step S105, the correction process under the basic axis angle is to adjust the positions of the first transverse main axis 2 and the second transverse main axis 3 on the first base and the second base, respectively.

[0079] This embodiment provides a more convenient method. Taking the first linear actuator as an example, the first transverse spindle 2 is mounted on the first base. The first linear actuator drives the entire structure of the first transverse spindle 2 and the first base to move in the width direction. The first transverse spindle 2 can be secured to the first base using bolts or other means. This securement method offers the advantages of reliability and simplicity. In this case, the initial drive position of the first linear actuator corresponds to the base axis angle. At other angles, the drive values ​​executed by the first linear actuator are relatively small.

[0080] In one embodiment, in step S105, the selection rule of the basic axis angle is:

[0081] The sum of Zx and Zy at each axis angle is obtained, and the axis angle corresponding to the sum closest to the average of the maximum sum and the minimum sum is taken as the basic axis angle.

[0082] In this embodiment, a method is provided for selecting a basic axis angle based on the average of the maximum sum and the minimum sum, so that during the correction process, the lateral drive required to be performed on the first transverse main axis 2 and the second transverse main axis 3 is minimized and simple, and the possibility of error formation is also minimized.

[0083] In one embodiment, after step S1, the method includes:

[0084] S107, receiving the setting of the basic axis angle, and 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 to complete the correction process, wherein, ;

[0085] S108 , updating the first axis displacement x and the second axis displacement y under all axis angle conditions.

[0086] In this embodiment, considering that customers often test different bevel gear models using the bevel gear testing machine, but with a common model range, a base shaft angle is set. This minimizes the need for corrections during the calibration process. For example, if the various bevel gears a customer needs to test require shaft angles ranging from 45 to 70 degrees, the base shaft angle can be set to 60 degrees. After calibration at 60 degrees, the first and second transverse spindles 2 and 3 are aligned in the width direction. The first axis displacement x and second axis displacement y are then updated for all shaft angle conditions, providing a reference for subsequent processes.

[0087] In one embodiment, linear grating components for detecting displacement are provided corresponding to the width of the first transverse main axis 2 and the second transverse main axis 3 .

[0088] In this embodiment, the linear grating assembly enables the displacement of the first transverse spindle 2 and the second transverse spindle 3 in the width direction to be monitored, thereby enabling the detection and analysis of the operating accuracy of the first and second linear drives. Specifically, the model of the linear grating assembly is not a key issue.
