Description

Technical Field

[0001] The invention belongs to the technical field of wire stranding machine manufacturing, and in particular relates to an integrated welding manufacturing method for a wire stranding machine base. Background Art

[0002] A stranding machine is a device used to twist multiple cables or fibers together, and is widely used in industries such as power, communications, and aerospace;

[0003] The stranding machine will rotate at high speed during the movement, so the driving motor needs to be fixed;

[0004] In the general fixing method, in order to facilitate the installation and disassembly of the motor, the usual setting scheme is: two symmetrical fixing seats, each including a accommodating cavity, are set on the base to ensure that the axis center lines of the two fixing seats coincide, and then the two motors are installed in the two fixing seats respectively. At this time, since the axis center lines of the two fixing seats coincide, the two motor shafts in the fixing seats coincide, and then a cover plate is installed on each of the two motors, and the cover plate is screwed to the screw holes reserved in the base, thereby completing the wrapping and fixing of the motor, and ensuring that the rotating shafts of the two motors coincide.

[0005] However, in the above solution, the design of the removable cover and the base being screwed together has a low connection strength, and the motor needs to run at high speed for a long time, which exerts a large reaction force on the fixed seat. After the screw connection between the cover and the base is subjected to the reaction force for a long time, there is a probability that it will shift, making it impossible to fix the motor in place.

[0006] To this end, it is necessary to change the detachable base design of the motor into an integrated base design. At this time, there is no weak link in the entire structure and the fixing effect is stronger. However, for the integrated structure, there is no adjustment space after installation, so the accuracy needs to be guaranteed as much as possible during installation. Therefore, a method for integrated welding and manufacturing of a stranding machine base with high installation accuracy and good motor fixing effect is needed. Summary of the invention

[0007] In order to solve the above problems existing in the prior art, the present invention provides an integrated welding manufacturing method for a stranding machine base, which has the characteristics of high installation accuracy and good motor fixing effect.

[0008] The purpose of the present invention can be achieved through the following technical solutions:

[0009] A method for manufacturing an integrated welding base of a stranding machine comprises the following steps:

[0010] Step 1: Provide a connecting groove whose inner diameter is consistent with the outer diameter of the first fixture and the second fixture, place the first fixture and the second fixture on the connecting groove, and place the connecting groove on the base of the stranding machine;

[0011] Step 2: fine-adjust the positions of the first fixture and the second fixture so that the hollows of the first fixture and the second fixture are completely aligned;

[0012] Step 3: The first fixture and the second fixture are respectively connected to the connecting groove by welding, and the connecting groove is welded to the base of the stranding machine;

[0013] Step 4: Cut off the part other than the part connected with the first fixator or the second fixator.

[0014] As a preferred technical solution of the present invention, the step 2 further includes: respectively setting positioners on the first fixture and the second fixture, and judging whether the first fixture and the second fixture are completely aligned by whether the positioners on the two fixtures are aligned with each other.

[0015] As a preferred technical solution of the present invention, step two also includes: setting multiple locators, positioning the multiple locators relative to each other and uploading the deviation values ​​of the corresponding locators relative to themselves to the control module, and the control module determines whether the first fixer and the second fixer are completely aligned by judging the deviations of multiple pairs of locators.

[0016] As a preferred technical solution of the present invention, the step three also includes: detecting the deformation of the connecting groove during the welding process, and when the deformation exceeds the deformation threshold, executing step four in advance and then completing the welding.

[0017] As a preferred technical solution of the present invention, the step three also includes: during the welding process, increasing the threshold value as the number of welding points increases.

[0018] As a preferred technical solution of the present invention, step three also includes: during the welding process, increasing the deformation threshold to A1 times the initial value, where A1=log(x+0.1)+2, x=H / H0, H0 is the target weld point quantity, and H is the current weld point quantity.

[0019] As a preferred technical solution of the present invention, step one also includes: setting a control panel; step two also includes: uploading to the control panel whether the locators on the two fixtures are aligned with each other, and judging through the control panel whether the first fixture and the second fixture are completely aligned.

[0020] As a preferred technical solution of the present invention, it also includes step five: testing the first fixture and the second fixture, the testing steps include: periodic force test and vibration test, testing the vibration amplitude of the first fixture and the second fixture in the periodic force test and vibration test, and judging whether the vibration amplitude exceeds a threshold value.

[0021] As a preferred technical solution of the present invention, step five also includes: in the periodic test, assuming that the vibration amplitude is X, the longitudinal vibration amplitude is X1, and the lateral vibration amplitude is X2, X=(k1×X1+k2×X2) / (k1+k2).

[0022] The beneficial effects of the present invention are:

[0023] (1) By providing the connecting groove, when the first fixture and the second fixture are in the connecting groove, they can always overlap along the axial direction of the connecting groove during the installation process or in other time periods, so that the two fixtures can always be aligned. At the same time, when the two fixtures have a tendency to move along the radial direction of the connecting groove, the inner wall of the connecting groove can abut against them, thereby avoiding deviation of the two fixtures caused by external factors and improving the installation accuracy of the base;

[0024] (2) By increasing the threshold value as the number of welds increases during the welding process, when there are many welds, there is no need to respond to slight deformations, and the deformation threshold value is increased; when there are few welds, it is necessary to respond to slight deformations, and the deformation threshold value is reduced, thereby ensuring positioning accuracy and work efficiency;

[0025] (3) By setting up multiple pairs of positioners, the installation accuracy of the two fixtures is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0033] See also Figure 1-3 , a method for manufacturing an integrated welding base of a stranding machine, comprising the following steps:

[0034] Step 1: Set a connecting groove 1 whose inner diameter is consistent with the outer diameter of the first fixture 2 and the second fixture 2, place the first fixture 2 and the second fixture 2 on the connecting groove 1, and place the connecting groove 1 on the base of the stranding machine;

[0035] Specifically, the two fixtures 2 are both quadrangular prism-shaped entities with a cylindrical hollow 3 hollowed out in the middle, and the cylindrical hollow 3 is used to accommodate the motor. In this case, the two fixtures 2 are bases;

[0036] The two fixators 2 are in the same orientation when visiting, and the lower outer surfaces of the two fixators 2 have the same shape;

[0037] The connecting groove 1 is a quadrangular column groove, and the axial length of the connecting groove 1 is at least four times the groove width;

[0038] The connecting groove 1 is used to place two fixers 2. The internal shape of the connecting groove 1 is consistent with the external shape of the two fixers 2. At this time, when the two fixers 2 are placed in the connecting groove 1, the inner wall of the connecting groove 1 fits with the outer walls of the two fixers 2 respectively. At this time, the connecting groove 1 completes the fixation of the relative positions of the two fixers 2 along its own axial direction;

[0039] When the first fixture 2 and the second fixture 2 are in the connection groove 1, they are overlapped along the axis of the connection groove 1, that is, during the installation process or in other time periods, the two fixtures 2 can be aligned along the axial direction of the cylindrical hollow 3 of the fixture 2, so as to complete the alignment during the installation process. After the fixture 2 is installed, the axial directions of the two motors can also be aligned after the motor is installed.

[0040] Optionally, the connecting groove 1 is provided with reinforcing ribs, and the reinforcing ribs are arranged along the direction of the connecting groove 1 .

[0041] By setting the connecting groove 1, when the first fixture 2 and the second fixture 2 are in the connecting groove 1, they can always overlap along the axial direction of the connecting groove 1 during the installation process or in other time periods, so that the two fixtures 2 can always be aligned. At the same time, when the two fixtures 2 have a tendency to move radially along the connecting groove 1, the inner wall of the connecting groove 1 can abut against them, thereby avoiding the deviation of the two fixtures 2 caused by external factors and improving the installation accuracy of the base.

[0042] After installation, due to the processing error of the fixture 2 itself, when the two fixtures 2 overlap along the axial direction of the connecting groove 1, the axial direction of the cylindrical hollow 3 does not overlap. Therefore, the second step is further included: fine-tuning the positions of the first fixture 2 and the second fixture 2 so that the hollows 3 of the first fixture 2 and the second fixture 2 are completely aligned;

[0043] Specifically, the outer surface of the fixture 2 can be cut so that the cylindrical hollow 3 can still be aligned after one of the fixtures 2 is set in the connecting groove 1, or the fixture 2 with a smaller processing error can be replaced to achieve fine adjustment.

[0044] After the execution of step 2, it means that the fixture 2 as the base has been installed at the corresponding position. At this time, the base installed at the corresponding position can be formally fixed to the base of the stranding machine. At this time, step 3 is executed: the first fixture 2 and the second fixture 2 are respectively welded to the connecting groove 1 by welding, and the connecting groove 1 is welded to the base of the stranding machine;

[0045] Specifically, the two fixers 2 are connected to the connection groove 1 by welding respectively, and then the connection groove 1 is fixed to the stranding machine base by welding.

[0046] After the installation is completed, since the base eventually needs to be installed with a motor, the motors need to be installed with discs coaxial with their own rotating shafts, and the two discs constitute a cradle, and the connection slot 1 between the two fixing seats or the two motors has a probability of blocking the installation of the cradle. At the same time, after the installation is completed, the positions of the two fixtures 2 are fixed by the structure formed by welding, and there is no need to rely on the connection slot 1 itself for fixing. Therefore, step 4 is performed: the part other than the connection part with the first fixture 2 or the second fixture 2 is cut off;

[0047] After the cutting, the connecting groove 1 between the two fixing seats or the two motors no longer exists, so as to prevent the connecting groove 1 from hindering the subsequent operation.

[0048] In the process of fine-tuning in the above step 2, specifically: positioners are respectively provided on the first fixture 2 and the second fixture 2, and whether the first fixture 2 and the second fixture 2 are completely aligned is determined by whether the positioners on the two fixtures 2 are aligned with each other;

[0049] Specifically, in step 2: multiple positioners are set, multiple positioners are positioned with each other and the deviation values ​​of the corresponding positioners relative to themselves are uploaded to the control module, and the control module determines whether the first fixture 2 and the second fixture 2 are completely aligned by judging the deviations of multiple pairs of positioners;

[0050] A plurality of positioners are arranged in pairs, and each pair of positioners is respectively installed at the same position of two fixtures 2. At this time, if the two fixtures 2 are aligned, each pair of positioners is arranged directly opposite to the other fixture 2 in the same pair;

[0051] By providing a plurality of paired positioners, the installation accuracy of the two fixtures 2 is further improved.

[0052] During the welding process, the connection point formed by welding has a probability of applying stress to the connection slot 1. At this time, the connection slot 1 is deformed. Even if the deformation is not significant enough to affect the alignment of the two fixtures 2, stress will still be generated in the fixed structure. In the process of the fixture 2 fixing the motor for a long time, the stress here and the reaction force of the motor will weaken the structural strength of the fixture 2. Therefore, step three also includes: detecting the deformation of the connection slot 1 during the welding process. When the deformation exceeds the deformation threshold, step four is performed in advance, and then the welding is completed;

[0053] When the connection point formed by welding has a probability of applying stress to the connection groove 1, it will cause a slight deformation of the connection groove 1. When the deformation is too large, it means that the impact is significant, and the deformation will be transmitted along the connection groove 1 to the other fixing seat. For an object with a larger size in a certain direction, the stress has a greater impact. Therefore, step 4 needs to be performed in advance to shorten the size of the connection groove 1 along its own axial direction, reduce the impact of stress, release stress, and avoid deformation along the connection groove 1. The other fixing seat is affected. After cutting, since there is already a welding point, the welding point pair can be relied on to keep the relative positions of the two fixtures 2 consistent after cutting;

[0054] As the number of welds increases, the resistance to deformation increases, and at this time, the slight deformation no longer affects the fixation of the fixture 2. Therefore, step three also includes: during the welding process, increasing the threshold value as the number of welds increases;

[0055] Specifically, during the welding process, the deformation threshold is increased to A1 times the initial value, where A1 = log(x + 0.1) + 2, x = H / H0, H0 is the target weld point amount, and H is the current weld point amount;

[0056] When there are many solder joints, there is no need to respond to slight deformations. At this time, A1=log(x+0.1)+2 is larger, and the deformation threshold is increased;

[0057] When there are fewer solder joints, they need to respond to slight deformations. At this time, A1=log(x+0.1)+2 is smaller, and the deformation threshold is reduced.

[0058] By increasing the threshold value as the number of welds increases during the welding process, when there are many welds, there is no need to respond to slight deformations and the deformation threshold value is increased; when there are few welds, it is necessary to respond to slight deformations and the deformation threshold value is lowered, thereby ensuring positioning accuracy and work efficiency.

[0059] Step one also includes: setting a control panel; said step two also includes: uploading to the control panel whether the locators on the two fixtures 2 are aligned with each other, and judging through the control panel whether the first fixture 2 and the second fixture 2 are completely aligned.

[0060] After the installation is completed, testing is required, and this also includes step five: testing the first fixture 2 and the second fixture 2. The testing steps include: periodic force testing and vibration testing. In the periodic force testing and vibration testing, the vibration amplitudes of the first fixture 2 and the second fixture 2 are tested to determine whether the vibration amplitude exceeds a threshold.

[0061] Specifically, in the periodic test, let the vibration amplitude be X, the longitudinal vibration amplitude be X1, and the lateral vibration amplitude be X2, then X = (k1×X1+k2×X2) / (k1+k2), where k1>k2, k1 and k2 are input into the control module in advance by the operator according to the actual situation;

[0062] Specifically, the longitudinal vibration is the part of the vibration perpendicular to the axial direction of the hollow 3 and perpendicular to the bottom of the connecting groove 1, and the transverse vibration is the part of the vibration perpendicular to the axial direction of the hollow 3 and parallel to the bottom of the connecting groove 1;

[0063] In actual use, the connection groove 1 limits the fixture 2 from both sides of the hollow 3 axis, so the connection groove 1 can assist the fixture 2 in resisting the lateral vibration, while the longitudinal vibration cannot be offset by the connection groove 1. Therefore, in the test, more attention should be paid to the longitudinal vibration amplitude. In the process of measuring the vibration amplitude, the weight of the longitudinal vibration amplitude should be amplified and the weight of the lateral vibration amplitude should be reduced.

[0064] By setting the vibration amplitude to X, the longitudinal vibration amplitude to X1, and the lateral vibration amplitude to X2, we have X=(k1×X1+k2×X2) / (k1+k2), where k1>k2. This allows us to increase the weight of the longitudinal vibration amplitude and reduce the weight of the lateral vibration amplitude when the longitudinal vibration cannot be offset by the limit of the connecting slot 1 and more attention needs to be paid to the longitudinal vibration amplitude during the test.

[0065] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.

However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
