Description

Technical Field

[0001] This utility model relates to the field of driver installation technology, and specifically to an auxiliary device for a servo driver. Background Technology

[0002] Servo drives are the core component for controlling servo motors. To meet the high precision requirements of servo motors, they can convert command signals from the control system into precise control signals such as motor current, speed, and position, thereby enabling more complex control logic and higher dynamic performance. They are widely used in industrial automation fields, such as CNC machine tools, robots, printing equipment, and packaging machinery. They have advantages such as fast response speed, high control accuracy, and good stability, and are one of the key components for achieving automation and intelligence in modern industrial production.

[0003] During the assembly of the servo drive, the servo drive and the mounting plate are fixedly installed by a threaded connection. At the same time, studs that provide external functions need to be assembled on the mounting plate. However, in actual assembly, the installation positions of the servo drive and the studs need to be manually positioned, which can easily lead to incorrect installation orientation of the servo drive and stud installation failure due to deviation in the stud installation.

[0004] Therefore, there is an urgent need for an auxiliary device for servo drives to solve the problem of lack of installation positioning and installation guidance in the servo drive assembly process. Utility Model Content

[0050] Before detailing the specific embodiments of the technical solution of this application, we will first disclose the application scenarios suitable for supporting the implementation of the technical solution of this application.

[0051] The technical solution of this application is applicable to the field of driver installation technology, and is particularly applicable to scenarios involving assisting in the positioning of servo driver installation. In this context, the technical solution of this application can be applied in a typical servo driver installation process. It is understood that, in addition to the servo driver provided in the embodiments of this application, the auxiliary device for the servo driver proposed in this application is also applicable to other servo driver installation processes involving assisted positioning.

[0052] Please see Figure 10 In existing technologies, servo drives, as a core component for controlling servo motors, can convert command signals from the control system into precise control signals such as current, speed, and position of the motor, addressing the high precision requirements of servo motors. This enables more complex control logic and higher dynamic performance, and they are widely used in industrial automation fields such as CNC machine tools, robots, printing equipment, and packaging machinery. They possess advantages such as fast response speed, high control precision, and good stability, making them one of the key components for achieving automation and intelligence in modern industrial production.

[0053] In the actual installation process, the servo driver 1000 first needs to be installed on the driver base plate 1100. Since the threaded connectors 1400 on the servo driver 1000 are symmetrically positioned, it is easy to install them in the wrong direction or backwards. In order to solve the problem of preventing reverse installation, the servo driver 1000 needs to be positioned during the installation process. Secondly, as the core component of the servo motor, after the servo driver 1000 is installed on the driver base plate 1100, the studs 1300 need to be assembled to connect the assembled servo driver to the servo motor. Therefore, the installation and positioning of the studs 1300 is also important. Moreover, the threads of both the studs 1300 and the threaded connectors 1400 need to be aligned during the installation process. If there is a deviation during installation, it will cause the threads to fail, resulting in loosening or even falling off of the assembly structure, affecting the stability of the servo driver components. Therefore, the threaded connection position also needs to be positioned. At the same time, the auxiliary positioning can also shorten the installation time and solve the problem of low installation efficiency.

[0054] To address the aforementioned technical problems, this application proposes an auxiliary device for a servo drive, which aims to provide a general concept for the installation, positioning, and connector guidance of the servo drive.

[0055] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0056] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," and "fourth," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0057] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0058] See Figures 1 to 10 This utility model discloses an auxiliary device for a servo driver, including a device body 100, the device body 100 including at least one mounting area 100A; a first positioning unit 200, the first positioning unit 200 including at least three first positioning parts 210 erected on the edge of the mounting area 100A for positioning the mounting position of the servo driver; a second positioning unit 300, the second positioning unit including at least four second positioning parts 310 erected on the edge of the device body 100 for positioning the mounting position of the driver base plate; and a guide unit 400, the guide unit 400 including a plurality of stud guide holes 410 and a plurality of threaded guide holes 420, the stud guide holes 410 and threaded guide holes 420 being formed on the device body 100 for guiding the assembly of the servo driver.

[0059] Optionally, the main body 100 of the device, which supports the servo driver 1000 and the driver base plate 1100, can be a plate structure or a mesh structure. The first positioning unit 200, the second positioning unit 300, and the guiding unit 400 can be integrally formed with the main body 100 of the device or assembled separately. Those skilled in the art can design each unit module according to the actual servo driver installation requirements. This embodiment does not impose any limitations.

[0060] The mounting area 100A is used to position a single servo drive 1000 so as to fix the servo drive 1000 on the drive base plate 1100. It can be understood that, depending on the number of different servo drives 1000, the main body 100 of the device may include multiple mounting areas 100A.

[0061] As an example, see Figure 1 An exemplary embodiment of this application illustrates a device body 100 including two mounting areas 100A for assisting in the installation of, for example... Figure 10 The servo driver 1000 is shown.

[0062] The first positioning unit 200, through the first positioning part 210, confines the servo driver 1000 within the mounting area 100A to prevent the servo driver 1000 from shaking or falling off during installation. It is understood that the distance, height, and size between the first positioning parts 210 can be designed according to the adaptation parameters required by the actual servo driver 1000. As a preferred method, see [reference needed]. Figure 2 In this preferred embodiment, three first positioning parts 210 are used to form a three-point positioning of the servo driver 1000. This not only stabilizes the position of the servo driver 1000, but also leaves room for adjustment of the position of the servo driver 1000 in a moving direction, which facilitates flexible operation of the servo driver installation by the user. It can be understood that the number of first positioning parts 210 arranged along the width direction of the device body 100 and with the center line of the length direction of the device body 100 as the axis can be adjusted according to the actual requirements for the fixation of the servo driver. As long as the first positioning parts 210 include the three-point positioning method, the positioning of the servo driver 1000 can be realized. Increasing the number of first positioning parts 210 on the basis of three-point positioning can make the servo driver 1000 more stable. Those skilled in the art can make adjustments based on actual costs and requirements.

[0063] The second positioning unit 300, through the second positioning part 310, restricts the driver base plate 1100 to the device body 1000. During installation, the driver base plate 1100 is positioned above the servo driver 1000, and the servo driver 1000 needs to be mounted on the driver base plate 1100. Therefore, the second positioning part 310 provides stable positioning of the driver base plate 1100, which serves as the mounting substrate. Thus, compared to the three-point positioning method used for the servo driver 1000, a four-point positioning method is used for the driver base plate 1100, meaning at least four points are positioned on the device body. The second positioning parts 310 at the four bottom corners of the 100 limit the driver base plate 1100 to prevent it from shaking or falling off during the installation of the servo driver 1000. It is understood that the number, size, spacing and other parameters of the second positioning parts 310 can also be adjusted according to the actual driver base plate 1100 on which the servo driver is installed. On the basis of four-point positioning through four second positioning parts 310, the number of second positioning parts 310 can be further increased to achieve a more stable positioning effect, but designers need to consider the actual cost.

[0064] The guiding unit 400 includes multiple stud guide holes 410 and threaded guide holes 420 formed on the main body 100. The stud guide holes 410 assist in positioning the stud 1300 on the driver base plate 1100. During actual installation, the driver base plate 1100, fixed by the second positioning unit 300, is positioned so that the stud 1300 can be aligned with and pass through the stud guide holes 410 to install it onto the driver base plate 1100. It is worth noting that the stud 1300 is longer than the threaded connector 1400. The connection method for installing the stud 1300 is also... The stud 1300 is a threaded connection. One end of the stud 1300 is the rotational force-bearing end, while the other end is the mounting end of the contact driver base plate 1100. An excessively long stud 1300 may cause deviations in the actual installation position of the mounting end. The threads of the mounting end and the threads of the driver base plate 1100 may not be fully engaged, resulting in a deviation and failure of the threaded connection. Therefore, in addition to assisting in guiding and positioning the installation position of the stud 1300, the diameter of the stud guide hole 410 also restricts the threaded connection operation of the stud 1300, thereby ensuring that the threaded connection of the stud 1300 is effective and stable during installation and reducing the risk of detachment when connecting an external servo motor.

[0065] In an optional embodiment, please refer to Figures 1-2The first positioning part 210 is disposed on the center line of the device body 100 along the length direction, and the first positioning part 210 is disposed on the center line of the device body 100 along the width direction. The first positioning parts 210 disposed along the center line of the device body 100 along the length direction are arranged symmetrically in pairs. The first positioning unit 200 can effectively reduce the servo driver 1000 from shaking or loosening in the horizontal direction of the mounting area 100A by assisting in positioning the servo driver 1000. The first positioning units 200 disposed in pairs along the center line of the device body 100 along the length direction can further assist in positioning the servo driver 1000 and prevent the servo driver 1000 from shaking or loosening in the horizontal direction of the mounting area 100A. At the same time, the position where the first positioning part 210 is not disposed can be used to adjust the position of the servo driver 1000 and provide a reserved space for detachment when the installation is completed. This allows the servo driver auxiliary device provided in this application to completely realize the process from installation to unloading, and ensures the robustness of the assembly structure and the accuracy of the auxiliary positioning during the installation process.

[0066] In one specific embodiment, the first positioning part 210 is a cylindrical structure, and the first positioning part 210 includes a first positioning surface 211 for abutting the servo driver, and the first positioning surface 211 is a plane. The shape of the first positioning part 210 can also be other non-column structures or a combination of multiple structures with blocking function. The first positioning surface 211 is used to abut against the edge of the servo driver 1000. The first positioning surface 211 can be smooth, rough, or textured to increase friction and prevent the servo driver 1000 from loosening. It is understood that the servo driver 1000 usually includes a silicon plate, electronic components, pins, and interfaces. The first positioning part 210 is mainly used to abut against the silicon plate of the servo driver 1000. The silicon plate is usually a quadrilateral plate structure. Therefore, setting the first positioning surface 211 to a plane can fully abut against the side of the silicon plate to increase the contact area, thereby increasing the friction that the servo driver 1000 needs to overcome when moving, thereby preventing the relative sliding of the servo driver 1000 and positioning the servo driver 1000 in a fixed position in the mounting area 100A. Those skilled in the art will understand that, in addition to a plane, the required first positioning surface 211 can also be adjusted according to the design of the silicon plate.

[0067] In a further embodiment, a limiting buckle 212 is provided on the first positioning surface 211 extending into the mounting area 100A for limiting the driver base plate 1100. The limiting buckle 212 can further prevent the driver base plate 1100 from detaching from the auxiliary device. The limiting buckle 212 can be an elastic element. After the servo driver 1000 and the driver base plate 1100 are assembled, the driver base plate 1100 can be lifted to detach from the limitation of the limiting buckle 212, thereby unloading the installed servo driver.

[0068] In one specific embodiment, the second positioning part 310 is disposed at the inner corner of the device body 100. The second positioning part 310 is a cylindrical structure. The second positioning part 310 includes a second positioning surface 311 for abutting against the driver base plate. The mutually perpendicular second positioning surfaces 311 surround to form a right-angled inner corner surface that abuts against the outer corner of the driver base plate. The second positioning part 310 is located at the inner corner of the device body 100, forming four fixed points at the bottom corners. It should be explained that since the device body 100 has a certain height, its main function is to position and restrict the servo driver 1000 and driver base plate 1100 to be installed within the device body 100. Therefore, the device body 100 can be represented as a box with an upward opening. If the box is quadrilateral in a two-dimensional plane, then the inner corners are the four bottom corner positions enclosed by the box. In a specific embodiment, the driver base plate 1100 has a quadrilateral structure and is a parallel right-angled quadrilateral. Therefore, the two second positioning surfaces connected at the bottom corners are perpendicular to each other to contact the outer corners of the driver base plate 1100. According to the explanation of the bottom corners in this application, the outer corners are the right angles corresponding to the outer contact surfaces of the four bottom corners of the quadrilateral structure of the driver base plate 1100.

[0069] Furthermore, the second positioning parts 310 located at the four inner corners can form a four-point positioning for the driver base plate 1100, preventing the driver base plate 1100 from detaching during installation. In addition, the second positioning surfaces 311 adapted to the outer corners of the driver base plate are designed to form right-angled inner corner surfaces, which can effectively reduce the shaking of the driver base plate 1100. Especially during the installation process, it ensures that the installation of the stud 1300 and the threaded connector 1400 will not deviate, improving the accuracy and practicality of the auxiliary installation.

[0070] In an optional embodiment, the guide units 400 are arranged in an array within the mounting area 100A, wherein the number of stud guide holes 410 is at least four, the number of threaded guide holes 420 is at least four, and the circumferential edge of the threaded guide holes 420 is provided with a boss 421 along the height direction. Typically, to mount the servo driver 1000 onto the driver base plate 1100, at least four threaded connectors 1400 are required to be threaded to the driver base plate 1100 at the four bottom corners of the servo driver 1000 silicon board. Similarly, to achieve a stable effect, at least four studs 1300 are also required to externally connect the mounted servo driver 1000.

[0071] Furthermore, during the actual installation of the servo driver 1000, the stud 1300 is longer than the threaded connector 1400, resulting in a different vertical height within the mounting area 100A, such as... Figure 4 and Figure 5 As shown, in actual installation, only the back of the device body 100 with stud guide hole 410 and threaded connector 1400 is visible during the installation process. Due to the difference in vertical height and the requirement for the verticality of the stud 1300 and threaded connector 1400, it is necessary to unify the height of stud guide hole 410 and threaded connector 420 from the mounting plane of servo driver 1000, as well as the verticality of the threaded connection formed by stud guide hole 410 and threaded connector 420 along the height direction under the unified height. This verticality can reduce the deviation that occurs during threaded connection and ensure the effectiveness of threaded connection. Therefore, in this embodiment, a boss 421 is provided on the edge of threaded connection hole 420. The boss 421 surrounds threaded connection hole 420 to equivalently replace the part of threaded connector 1400 that is shorter than stud 1300, thereby realizing the unified installation and fixation of stud 1300 and threaded connector 1400 and improving the stability of servo driver assisted installation.

[0072] Furthermore, such as Figure 5 and Figure 10 As shown, since the positions of the stud 1300 and the threaded connector 1400 are determined according to the actual design of the servo driver 1000 and the driver base plate 1100, if the installation positions of the stud 1300 and the threaded connector 1400 are close, the two cross-sectional circles of the stud guide hole 410 and the threaded guide hole 420 on the plane of the device body 100 can be intersected. That is, the center-to-center distance between the center of the stud guide hole 410 and the center of the threaded guide hole 420 is less than the sum of the radius of the stud guide hole 410 and the radius of the threaded guide hole 420. In this way, more stud guide holes 410 and threaded guide holes 420 can be set to assist in the installation of the servo driver and the stud.

[0073] In an optional embodiment, please refer to Figure 6 The auxiliary device further includes a third positioning unit 500, which is located on the center line of the main body 100 of the device along the width direction. The third positioning unit 500 has a protrusion structure to divide the mounting area 100A and limit the servo drives in adjacent mounting areas 100A. The third positioning unit 500 can be set in multiples according to the number of servo drives 1000, thereby dividing multiple individual servo drives 1000 and mounting them on the mounting area 100A of the driver base plate. It can be understood that the height of the third positioning unit 500 is set according to the height of the electronic components on the servo drive 1000, and the width of the third positioning unit 500 is set according to the required spacing distance of the servo drives 1000. That is, the width of the third positioning unit 500 is approximately equal to the distance between two adjacent servo drives 1000 on the driver base plate 1100, thereby improving the accuracy of the auxiliary servo drive 1000 in positioning and installation.

[0074] In an optional embodiment, please refer to Figures 1-7 The main body 100 of the device is provided with a fourth positioning unit 600 in the installation area 100A. The fourth positioning unit 600 includes a positioning base plate 610 and a positioning baffle 620. The positioning base plate 610 and the positioning baffle 620 together form a positioning area 630 for positioning electronic components on the servo driver. The combination of the base plate 610 and the positioning baffle 620 to form the positioning area 630 is set according to the structure of the electronic components on the servo driver 1000. The electronic components can be capacitors or power supplies, etc. In addition to using the position of the electronic components to assist in the positioning of the servo driver 1000, it can also be used to protect the electronic components 1200, avoid the electronic components 1200 from being impacted or bumped during installation, and reduce the installation risk of the servo driver installation process.

[0075] In an optional embodiment, please refer to Figures 7-8 The main body 100 of the device is provided with a fifth positioning unit 700 on one side of the fourth positioning unit 600 for raising the height of the servo driver panel. A gap is left between the fourth positioning unit 600 and the fifth positioning unit 700. This gap can be used to accommodate the pins on the servo driver 1000. In actual installation, the fifth positioning unit 700 will abut against the silicon plate of the servo driver 1000, limiting the height of the servo driver 1000 to a plane below it that can accommodate the pins, thus preventing damage to the components on the servo driver 1000. It also allows a certain height difference to be formed in the vertical direction between the plane where the main body 100 of the device and the plane where the servo driver 1000 is located, which helps to achieve the verticality and height requirements of the threaded connection.

[0076] In an optional embodiment, the first positioning part 210 is asymmetrically arranged with the center line of the device body 100 along the width direction as the axis, so that the first positioning part 210 and the second positioning part 310 located at one end of the device body 100 constitute a fixed end 800 for assisting in the mounting of the servo driver, and the second positioning part 310 located away from the fixed end 800 constitutes an unloading end 900 for assisting in the unloading of the servo driver. The first positioning parts 210 arranged along the center line of the length direction of the device body 100 are arranged symmetrically in pairs. The auxiliary positioning of the servo driver 1000 by the first positioning unit 200 can effectively reduce the swaying or loosening of the servo driver 1000 in the horizontal width direction in the mounting area 100A, rather than being arranged in pairs along the length direction of the device body 100. The fixed end 800 formed by the first positioning unit 200 on the center line and the adjacent second positioning part 310 can further assist in positioning the servo drive 1000, preventing the servo drive 1000 from swaying or loosening in the horizontal direction of the mounting area 100A. At the same time, the position where the first positioning part 210 is not provided can be used to adjust the position of the servo drive 1000. Moreover, at the unloading end 900 where the first positioning part 210 is not provided, there is a reserved unloading space between the closely spaced second positioning parts 310 to form an unloading end 900, which provides a reserved space for disassembly and removal when the installation is completed. This allows the servo drive auxiliary device provided in this application to completely realize the process from installation to unloading, and ensures the robustness of the assembly structure and the accuracy of the auxiliary positioning during the installation process.

[0077] The working principle of the auxiliary device for a servo driver provided in this application is as follows:
