Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing, and in particular to a device and method for adjusting, installing and detecting a lead screw of a special winding device. Background Art

[0002] The feed servo system of special winding equipment is an important part of the transmission system. It consists of a servo motor, a coupling, a ball screw nut pair (including a screw support), a polished rod, and a transmission table movement (mobile trolley).

[0003] The feed servo system of the special winding equipment is a position following and positioning system. Its function is to quickly, accurately and frequently reciprocate the motion commands issued by the special winding equipment system, and accurately control the coordinate motion of the trolley feed transmission chain. Its performance determines many performances of the special winding equipment, such as mobile position accuracy and positioning accuracy, etc. Therefore, it is necessary to perform precision testing of the motor, motor seat, and screw support seat during installation. By installing and adjusting the vertical and horizontal accuracy of the motor, the vertical and horizontal accuracy of the motor seat, and the accuracy of the screw support seat, the motor, motor seat, and support seat can be adjusted to be in a straight line in the vertical and horizontal directions, ultimately ensuring the accuracy of the screw installation and processing qualified products.

[0004] During the operation of special winding equipment, there is residual glue during use. On-site operators or maintenance personnel regularly clean up the residual liquid. In addition, long-term use leads to aging, which leads to the coaxiality of the screw shaft and the motor shaft being out of tolerance.

[0005] When maintenance personnel install and adjust the screw operation method of special winding equipment, they need to clean the residual liquid on the motor positioning reference and the screw positioning reference surface. After cleaning, when installing the screw, they need to check the position accuracy of the motor seat, screw seat and coupling.

[0006] The current detection method is to measure with a feeler gauge, and the detection accuracy is out of tolerance. At the same time, there is no special detection tooling for the motor seat and the screw seat. Generally, the horizontal and vertical accuracy of the motor seat and the screw seat is detected by detecting the eccentricity. As a result, when the maintenance personnel replace the screw and coupling, the motor seat and the screw seat are indirectly detected by detecting the eccentricity of the motor shaft and the screw shaft during installation and adjustment, resulting in the motor seat and the four seats being out of tolerance during installation and adjustment, or accelerating the damage of the screw and the coupling.

[0007] Therefore, based on the screw shaft installation detection accuracy standard, we independently developed a special winding equipment screw installation adjustment detection device. Through this device, we invented a special winding equipment screw adjustment installation detection method, which makes the special winding equipment screw installation adjustment high-quality and accurate, and extends the service life of the screw and coupling. Summary of the invention

In addition, in order to simplify the drawings, the same or similar technical features may be marked only in one place in the same drawing.

[0047] In the present invention, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0048] The following is combined with Figure 1 -Attached Fig.11 The present invention will be described in detail.

[0049] Embodiment 1:

[0050] As attached Figure 1 ~Attached Figure 8 As shown, a special winding equipment screw adjustment, installation and detection device includes a machine tool body 3, on which a feed servo mechanism is provided, and the feed servo mechanism includes a ball screw 6 with a screw shaft 9 and a motor 7 with a motor shaft 10, and a corrector 4 is installed between the screw shaft 9 and the motor shaft 10, and the coaxiality of the screw shaft 9 and the motor shaft 10 is detected by a magnetic detection mechanism.

[0051] Working principle:

[0052] During the operation of the special winding equipment, due to the residual glue during use, the on-site operator or maintenance personnel regularly cleans the residual liquid, coupled with the aging of long-term use, the coaxiality of the screw shaft 9 and the motor shaft 10 exceeds the tolerance by 0.02mm (the maximum allowable eccentricity of the two shafts of the coupling is 0.02mm), as shown in Table 1:

[0053]

[0054] Table 1 Two-axis concentricity tolerance table

[0055] Therefore, accuracy testing is required when installing the motor 7, the motor seat, and the screw support seat that supports the screw. Therefore, by installing and adjusting the vertical and horizontal accuracy of the motor, the vertical and horizontal accuracy of the motor seat, and the accuracy of the screw support seat, the vertical and horizontal directions of the motor 7, the motor seat, and the screw support seat are in a straight line, ultimately ensuring the accuracy of the screw installation, thereby processing qualified products.

[0056] Furthermore, it can also be considered in the embodiment that the corrector 4 is two semi-cylinders connected by bolts.

[0057] In this embodiment, as shown in the attached Fig. 9 ~Attached Fig.10As shown, the corrector 4 for making the screw shaft 9 and the motor shaft 10 coaxial is used after the motor seat is adjusted to be qualified and the motor 7 is installed. The screw shaft 9 is preliminarily adjusted and fixed by the corrector 4, and the screw shaft 9 and the motor shaft 10 are fixed by bolts. After correction, the corrector 4 is removed.

[0058] Furthermore, in an embodiment, it can also be considered that the magnetic detection mechanism includes a movable magnetic base 81, and the magnetic base 81 is connected to a micrometer 82, and the head of the micrometer 82 detects the coaxiality by contacting the upper busbar and side line of the screw shaft 9 and the motor shaft 10.

[0059] Furthermore, it can also be considered in the embodiment that it also includes a support plate 1 installed on the machine tool body 3, the support plate 1 is provided with a horizontally movable slider 2, and the magnetic table base 81 is fixedly installed on the slider 2.

[0060] In this embodiment, the slider 2 is used to support and fix the magnetic gauge base 81 and the micrometer 82. The support plate 1 is used to support the slider 2. By adjusting the horizontal and vertical directions of the support plate 1, it is ensured that the slider 2 and the magnetic gauge base 81 have a horizontal and vertical detection reference. Therefore, the accuracy of the support plate 1 is combined with the requirements of the screw installation detection accuracy (0.02mm) and the cumulative error accuracy (0.01mm). The horizontal plane accuracy and vertical main accuracy of the design support plate 1 are within 0.005mm.

[0061] Furthermore, in the embodiment, it can also be considered that the magnetic meter base 81 is made of magnetic material and has a switch, and the slider 2 moves left and right on the support plate 1 by friction. The micrometer 82 is turned on by turning on and off the magnetic meter base 81.

[0062] Furthermore, in the embodiment, it can also be considered that the support plate 1 and the machine tool body 3 are connected by a plurality of top screw threads. Figure 6 and attached Figure 8 As shown, a plurality of top screws can reinforce the connection between the support plate 1 and the machine tool body 3 .

[0063] Furthermore, in the embodiment, it can also be considered that the slider 2 is L-shaped, and its inner corner is closely attached to the top and side of the support plate 1 and moves through the magnet.

[0064] In this embodiment, the slider is designed to be L-shaped and is clamped at a right angle to the reference side of the support plate 1. The sliding slider 2 drives the magnetic base 81 and the micrometer 82 to move based on the accuracy of the reference side of the support plate 1.

[0065] As attached Figure 7As shown, the lower end of the L-shaped slider 2 can leave a height space, so that the top screw thread has enough height space to connect the support plate 1. The horizontal plane accuracy and vertical main accuracy of the L-shaped slider 2 are within 0.002mm.

[0066] Embodiment 2:

[0067] A method for adjusting and installing a lead screw of a special winding device, using a device for adjusting and installing a lead screw of a special winding device, comprises the following steps:

[0068] S1: Install and adjust the horizontal accuracy of the support plate 1;

[0069] First, use a level to adjust the horizontal accuracy of the machine tool body 3. The adjustment accuracy needs to be at the zero point. Then set the support plate 1 on the machine tool body 3. Then place two levels in a cross shape on the support plate 1. Adjust the horizontal accuracy of the support plate 1 relative to the machine tool body 3 by adjusting its position. The adjustment accuracy needs to be at the zero point.

[0070] S2: Adjust the parallel accuracy of the support plate 1;

[0071] Install the slider 2 on the support plate 1 with adjusted horizontal accuracy, install the magnetic base 81 with the micrometer 82 on the slider 2, and adjust the parallelism of the support plate 1 relative to the machine tool body 3. The adjustment accuracy of the parallelism needs to be at the zero point;

[0072] S3: pre-installed orthosis 4;

[0073] Pre-install the ball screw 6 and the motor 7 on the machine tool body 3, first install one end of the corrector 4 on the motor shaft 10 of the motor 7, and then install the other end of the corrector 4 on the screw shaft 9 on the ball screw 6 based on the motor shaft 10;

[0074] S4: adjusting the axis by detecting the upper busbar and the side busbar of the corrector 4;

[0075] Use the dial head of the micrometer 82 to touch the upper busbar and the side busbar of the corrector 4 to indirectly detect the coaxiality of the motor shaft 10 and the screw shaft 9. After the coaxiality meets the standard, remove the corrector 4.

[0076] S5: Check the installation accuracy of the screw shaft 9;

[0077] The upper busbar and the side busbar of the screw shaft 9 are detected by using the method of detecting the upper busbar and the side busbar of the "corrector" in step S4 to achieve the adjustment and installation accuracy of the screw shaft 9.

[0078] Furthermore, it can also be considered in the embodiment that in step S3, the detection values ​​of the upper busbar and the side busbar of the corrector 4 need to be within 0.005 mm.

[0079] Furthermore, in the embodiment, it can also be considered that in step S4, the adjustment and installation accuracy of the screw shaft 9 must meet the standard within 0.02 mm.

[0080] Working process:

[0081] In this embodiment, the level used is a strip level, such as Fig.11 As shown, it is used to detect whether the guide rails of machine tools and other equipment remain straight, ensuring the normal operation of the equipment and extending its service life. During the equipment installation process, the bar level can also be used to ensure the horizontal and vertical position of the mechanical equipment is correct, thereby improving the accuracy and stability of the equipment.

[0082] First, install and adjust the support plate 1 and the slider 2, and use the spirit level to adjust the horizontal accuracy of the machine tool body 3. The adjustment accuracy must be at the zero point. Then, adjust the accuracy of the support plate 1 relative to the machine tool body 3. The adjustment accuracy must be at the zero point. The purpose is to reduce the influence of other accuracy on the adjustment and installation of the detection screw.

[0083] The support plate 1 is adjusted to its horizontal and vertical precision by means of a level and a micrometer 82. The adjustment precision must be guaranteed to be adjusted to 0 mm, in order to eliminate excessive cumulative errors. Secondly, the magnetic base 81 with the micrometer 82 is fixed on the slider 2, and the micrometer 82 is slid on the support plate 1 to detect and adjust the parallelism between the support plate 1 and the machine tool body 3. The parallelism adjustment precision is at the zero point. After the above adjustment, the support plate 1 is absolutely horizontal and parallel relative to the machine tool body 3.

[0084] After adjustment, the screw shaft 9 and the motor shaft 10 can be pre-installed. First, pre-install the motor 7 and the ball screw 6, and then install the corrector 4. It is necessary to perform rough installation based on the motor shaft 10, adjust the screw shaft 9, and then use the slider 2 to drive the micrometer 82. Use the side and top of the support plate 1 as a reference to slide parallel to detect the upper busbar and side busbar at both ends of the shaft of the corrector 4. After the detection value is within 0.005mm, fix the screw shaft 9, and then use the method of detecting the upper busbar and side busbar of the corrector 4 to detect the upper busbar and side busbar of the screw shaft 9, so that the adjustment and installation accuracy of the shaft is within 0.02mm, and finally the qualified accuracy of the screw installation is achieved.

[0085] During the application of the above-mentioned adjustment method, after one year of application data statistics, it was found that the number of damages during the use of the screw was significantly reduced, from 17 abnormal damages of the coupling in 2021-2022 to only 1 abnormal damage in 2022-2023. It improved the quality of single inspection and adjustment, and digitized the inspection results. At the same time, it increased the efficiency of single inspection by 30%, and saved 30 minutes / person-time of single working hours.
