Description

Technical Field

[0001] This invention belongs to the field of stranding machine manufacturing technology, specifically relating to an integrated welding manufacturing method for a stranding machine base. Background Technology

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

[0003] The stranding machine rotates at high speed during operation, therefore, the drive motor needs to be fixed.

[0004] In a typical fixing method, to facilitate the installation and removal of the motor, the usual setup is as follows: two symmetrical fixing seats, each with its own receiving cavity, are set on the base, ensuring that the center lines of the two fixing seats coincide. Then, two motors are installed in the two fixing seats respectively. Since the center lines of the two fixing seats coincide, the shafts of the two motors in the fixing seats also coincide. Then, a cover plate is installed on each of the two motors, and the cover plate is screwed into the screw holes reserved in the base, thereby completing the enclosure and fixing of the motor, while ensuring that the rotating shafts of the two motors coincide.

[0005] However, in the above solution, the design of the detachable cover plate and the base being screwed together has low connection strength. Since the motor needs to run at high speed for a long time, the reaction force on the fixed seat is large. After the screw connection between the cover plate and the base is subjected to the reaction force for a long time, there is a possibility that it will shift and the motor cannot be fixed in its original position.

[0006] Therefore, the detachable base design of the motor needs to be changed to an integrated base design. At this time, there are no weak points in the entire structure and the fixing effect is stronger. However, for the integrated structure, there is no room for adjustment after installation. Therefore, it is necessary to ensure the accuracy as much as possible during installation. Thus, a welding manufacturing method for the integrated base of the stranding machine with high installation accuracy and good motor fixing effect is needed. Summary of the Invention

[0007] To address the aforementioned problems in the existing technology, this invention provides an integrated welding manufacturing method for a stranding machine base, which features high installation accuracy and good motor fixing effect.

[0008] The objective of this invention can be achieved through the following technical solutions:

[0009] A method for integrally welding and manufacturing a stranding machine base, comprising the following steps:

[0010] Step 1: Set a connecting groove with an inner diameter that matches the outer diameter of the first and second clamps. Place the first and second clamps on the connecting groove and place the connecting groove on the stranding machine base.

[0011] Step 2: Fine-tune the positions of the first and second fasteners to ensure that the cutouts of the first and second fasteners are perfectly aligned;

[0012] Step 3: Weld the first and second fixtures to the connecting grooves respectively, and weld the connecting grooves to the stranding machine base;

[0013] Step 4: Remove the area other than the connection point with the first or second fixator.

[0014] As a preferred embodiment of the present invention, step two further includes: setting locators on the first fixture and the second fixture respectively, and determining whether the first fixture and the second fixture are completely aligned by checking whether the locators on the two fixtures are aligned with each other.

[0015] As a preferred embodiment of the present invention, step two further includes: setting up multiple locators, the multiple locators positioning each other and uploading the deviation value of the corresponding locator relative to itself to the control module, and the control module determining whether the first fixer and the second fixer are completely aligned by judging the deviation of multiple pairs of locators.

[0016] As a preferred embodiment of the present invention, step three further includes: detecting the deformation of the connecting groove during the welding process; when the deformation exceeds the deformation threshold, step four is executed in advance, and then the welding is completed.

[0017] As a preferred embodiment of the present invention, step three further includes: increasing the threshold as the number of weld points increases during the welding process.

[0018] As a preferred embodiment of the present invention, step three further 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 amount, and H is the current weld point amount.

[0019] As a preferred embodiment of the present invention, step one further includes: setting a control panel; step two further includes: uploading information on whether the locators on the two fixers are aligned with each other to the control panel, and determining whether the first fixer and the second fixer are completely aligned through the control panel.

[0020] As a preferred embodiment of the present invention, the invention further includes step five: testing the first fixture and the second fixture, the testing steps including: periodic force test and vibration test, in which the vibration amplitude of the first fixture and the second fixture is tested, and it is determined whether the vibration amplitude exceeds the threshold.

[0021] As a preferred technical solution of the present invention, step five further includes: in the periodic test, let the vibration amplitude be X, the longitudinal vibration amplitude be X1, and the transverse vibration amplitude be X2, then X = (k1×X1 + k2×X2) / (k1 + k2).

[0022] The beneficial effects of this invention are as follows:

[0023] (1) By setting a connecting groove, when the first and second fixtures are in the state of the connecting groove, they can always overlap along the axis of the connecting groove during the installation process or 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 radially along the connecting groove, the inner wall of the connecting groove can abut against them, avoiding the deviation of the two fixtures caused by external factors and improving the installation accuracy of the base.

[0024] (2) By increasing the threshold as the number of weld points increases during the welding process, when there are many weld points, there is no need to react to minor deformations. When there are few weld points, there is a need to react to minor deformations. This increases the deformation threshold and ensures positioning accuracy and work efficiency.

[0025] (3) By setting multiple pairs of positioners, the installation accuracy of the two fixtures is further improved. Attached Figure Description

[0032] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0033] Please see Figure 1-3 A method for integrally welding and manufacturing a stranding machine base, comprising the following steps:

[0034] Step 1: Set a connecting groove 1 with an inner diameter that matches 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 stranding machine base.

[0035] Specifically, both fixtures 2 are quadrangular prisms with a cylindrical hollow 3 in the middle. The cylindrical hollow 3 is used to accommodate the motor. At this time, the two fixtures 2 are bases.

[0036] When the two fasteners 2 are installed, their orientations are the same, and the shapes of their lower outer surfaces are the same.

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

[0038] The connecting groove 1 is used to place two fixing devices 2. The internal shape of the connecting groove 1 is the same as the external shape of the two fixing devices 2. When the two fixing devices 2 are placed in the connecting groove 1, the inner wall of the connecting groove 1 fits against the outer wall of the two fixing devices 2 respectively. At this time, the connecting groove 1 completes the fixation of the relative position of the two fixing devices 2 along its own axial direction.

[0039] When the first fixture 2 and the second fixture 2 are in the state of the connecting groove 1, they coincide along the axis of the connecting groove 1. That is, during the installation process or other time periods, the two fixtures 2 can be aligned along the axis of the cylindrical hollow 3 of the fixture 2, thus completing the alignment during the installation process. After the fixtures 2 are installed and the motor is installed, the axes of the two motors can also be aligned.

[0040] Optionally, the connecting groove 1 is provided with reinforcing ribs, which 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 state of the connecting groove 1, they can always overlap along the axis of the connecting groove 1 during the installation process or 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, 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 machining error of the fixture 2 itself, when the two fixtures 2 coincide along the axis of the connecting groove 1, the axis of the cylindrical cutout 3 does not coincide. Therefore, step two is also included: fine-tuning the position of the first fixture 2 and the second fixture 2 so that the cutouts 3 of the first fixture 2 and the second fixture 2 are completely aligned.

[0043] Specifically, the outer surface of the cutter 2 can be used so that the cylindrical cutout 3 can still be aligned after one of the cutters 2 is set in the connecting groove 1, or the cutter 2 with smaller machining error can be replaced to achieve fine adjustment.

[0044] After step two is completed, the fixture 2, which serves as the base, has been installed in the corresponding position. At this time, the base installed in the corresponding position can be formally fixed to the stranding machine base. Then, step three is performed: the first fixture 2 and the second fixture 2 are welded to the connecting groove 1 respectively, and the connecting groove 1 is welded to the stranding machine base.

[0045] Specifically, the two fixing devices 2 are connected to the connecting groove 1 by welding, and then the connecting groove 1 is fixed to the stranding machine base by welding.

[0046] After installation, since the base will eventually need to install the motor, each motor needs to install a disc coaxial with its own rotating shaft. The two discs form a rocker arm. However, the connecting groove 1 between the two fixed seats or the two motors may block the installation of the rocker arm. At the same time, after installation, the positions of the two fixing devices 2 are fixed by the welded structure, without relying on the connecting groove 1 itself for fixation. Therefore, step four is performed: cut off the parts other than the connection part with the first fixing device 2 or the second fixing device 2.

[0047] After the cut, the connecting groove 1 between the two fixed seats or the two motors will no longer exist, preventing the connecting groove 1 from obstructing subsequent operations.

[0048] In the fine-tuning process of step two above, specifically: a locator is set on the first fixture 2 and the second fixture 2 respectively, and the alignment of the first fixture 2 and the second fixture 2 is determined by whether the locators on the two fixtures 2 are aligned with each other.

[0049] Specifically, in step two: multiple locators are set up, the multiple locators position each other and upload the deviation value of the corresponding locator relative to itself to the control module. The control module determines whether the first fixer 2 and the second fixer 2 are completely aligned by judging the deviation of multiple pairs of locators.

[0050] Multiple positioners are set in pairs, with each pair of positioners installed at the same location on the two fixtures 2. If the two fixtures 2 are aligned, each pair of positioners is set directly opposite the other fixture 2 in the same pair.

[0051] By setting multiple pairs of positioners, the installation accuracy of the two fixtures 2 is further improved.

[0052] During the welding process, the welded joint may apply stress to the connecting groove 1. At this time, the connecting groove 1 will deform. Even if the deformation does not significantly affect the alignment of the two fixtures 2, stress will still be generated in the fixing structure. During the long-term operation of the motor fixed by the fixture 2, 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 connecting groove 1 during the welding process. When the deformation exceeds the deformation threshold, step four is executed in advance, and then the welding is completed.

[0053] When the welded connection point has a probability of applying stress to the connecting groove 1, it will cause a slight deformation of the connecting groove 1. When the deformation is too large, it indicates that the impact is significant, and the deformation will be transmitted along the connecting groove 1 to the other fixed seat. For objects with larger dimensions in a certain direction, the stress impact is greater. Therefore, it is necessary to perform step four in advance to shorten the dimension of the connecting groove 1 along its own axial direction, reduce the stress impact, release the stress, and at the same time avoid the deformation from affecting the other fixed seat along the connecting groove 1. After cutting, since there are already weld points, the relative positions of the two fixtures 2 can be kept consistent by relying on the weld points.

[0054] As the number of weld points increases, the resistance to deformation increases, and at this point, minor deformations no longer affect the fixation of the fixture 2. Therefore, step three also includes: increasing the threshold as the number of weld points increases during the welding process.

[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 react to minor deformations. At this time, A1 = log(x + 0.1) + 2 is relatively large, thus improving the deformation threshold.

[0057] When there are fewer solder joints, it is necessary to respond to minute deformations. At this time, A1 = log(x + 0.1) + 2 is smaller, thus reducing the deformation threshold.

[0058] By increasing the deformation threshold as the number of weld points increases during the welding process, when there are many weld points, there is no need to react to minor deformations; when there are fewer weld points, there is a need to react to minor deformations; thus, the deformation threshold decreases, ensuring positioning accuracy and operational efficiency.

[0059] Step one also includes setting up the control panel; Step two also includes uploading information on whether the locators on the two fixtures 2 are aligned to the control panel, and using the control panel to determine whether the first fixture 2 and the second fixture 2 are completely aligned.

[0060] After installation, testing is required, which includes step five: testing the first fixture 2 and the second fixture 2. The testing steps include: periodic force test and vibration test. In the periodic force test and vibration test, the vibration amplitude of the first fixture 2 and the second fixture 2 is tested to determine whether the vibration amplitude exceeds the 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, and k1 and k2 are input into the control module in advance by the operator according to the actual situation.

[0062] Specifically, longitudinal vibration is the part of the vibration that is perpendicular to the axis of the hollow 3 and perpendicular to the bottom of the connecting groove 1, and transverse vibration is the part of the vibration that is perpendicular to the axis of the hollow 3 and parallel to the bottom of the connecting groove 1.

[0063] In actual use, the connecting groove 1 limits the fixing device 2 from both sides of the hollow 3 axis. Therefore, the connecting groove 1 can help the fixing device 2 resist lateral vibration, while the longitudinal vibration cannot be offset by the limiting of the connecting groove 1. Therefore, more attention needs to be paid to the longitudinal vibration amplitude in the test. In the process of measuring the vibration amplitude, the weight of the longitudinal vibration amplitude needs to be increased and the weight of the lateral vibration amplitude needs to be reduced.

[0064] By setting the vibration amplitude as X, the longitudinal vibration amplitude as X1, and the lateral vibration amplitude as X2, we have X = (k1×X1 + k2×X2) / (k1 + k2), where k1 > k2. This completes the process of increasing the weight of the longitudinal vibration amplitude and decreasing the weight of the lateral vibration amplitude when the longitudinal vibration cannot be offset by the limiting of the connecting groove 1 and more attention needs to be paid to the longitudinal vibration amplitude during the test.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
