Description

Technical Field

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

[0002] Dual-axis servo drives are a core component for controlling servo motors. Addressing the high precision requirements of servo motors, they convert command signals from the control system into precise control signals for the motor's current, speed, and position. This enables more complex control logic and higher dynamic performance. Widely used in industrial automation fields such as CNC machine tools, robots, printing equipment, and packaging machinery, they offer advantages such as fast response, high control precision, and good stability, making them a key component for achieving automation and intelligence in modern industrial production.

[0003] During the assembly process of a dual-axis servo drive, the drive and the base plate are fixedly assembled by a threaded connection. However, in actual assembly, the installation position of the drive needs to be manually positioned. Since the threaded connection points of the drive are arranged in a centrally symmetrical manner, it is easy to cause the drive to be installed in the wrong direction, which affects the assembly efficiency and the assembly yield.

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

[0005] To address the shortcomings of existing technologies, this utility model proposes an auxiliary device for a dual-axis servo drive, which can assist in positioning the drive base plate and guiding the drive installation position, avoiding misinstallation problems, improving assembly efficiency, and increasing the yield of assembled products.

[0006] The technical solution of this utility model is implemented as follows: An auxiliary device for a dual-axis servo drive includes: The device body has a mounting platform formed on its surface for receiving the driver base plate; At least two positioning parts are provided on the main body of the device for positioning the driver base plate on the mounting platform; At least two guide sections are provided on the mounting platform to guide the installation orientation of the driver.

[0007] In an optional embodiment, the positioning part is a positioning pin, which is engaged in the mounting positioning hole of the driver base plate by at least two positioning pins, so that the driver base plate is positioned on the mounting platform.

[0008] In an optional embodiment, the positioning part is configured as a group of at least two positioning pins, and the two positioning pins in each group of positioning parts are symmetrically arranged about the center line of the mounting platform.

[0009] In an optional embodiment, the guide includes a column and a stop located at the top of the column and extending horizontally into the mounting platform.

[0010] In an optional embodiment, the guide portions are spaced apart along the length of the device body at the edges of the device body, and the spacing between adjacent guide portions is greater than the width of the driver.

[0011] In an optional embodiment, the two ends of the device body along its length are recessed to form gripping portions for grasping the auxiliary device.

[0012] In one optional embodiment, the main body of the device has several hollowed-out sections.

[0013] In an optional embodiment, the device body and the guide portion are fixedly connected and integrally formed.

[0014] In an optional embodiment, the guide portion is detachably connected to the device body.

[0015] Compared with the prior art, the present invention has the following advantages: This utility model provides an auxiliary device for a dual-axis servo drive, comprising: a device body, at least two positioning parts, and at least two guiding parts. The surface of the device body forms a mounting platform for receiving the drive base plate. The positioning parts are disposed on the device body for positioning the drive base plate on the mounting platform. The guiding parts are disposed on the mounting platform for guiding the installation direction of the drive. By receiving the drive base plate of the dual-axis servo drive on the mounting platform of the device body, and by positioning the drive base plate on the mounting platform using the positioning parts to prevent the drive base plate from shaking or shifting, and by guiding the drive's installation position and direction on the drive base plate using the guiding parts, installation errors can be prevented, effectively improving the assembly efficiency of the dual-axis servo drive and ensuring a high assembly yield.

[0019] 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.

[0020] The technical solution of this application is applicable to the field of driver installation technology, and is particularly applicable to scenarios involving auxiliary positioning of dual-axis 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 dual-axis servo driver provided in the embodiments of this application, the auxiliary device for dual-axis servo drivers proposed in this application is also applicable to other dual-axis servo driver installation processes involving auxiliary positioning.

[0021] Please see Figure 3 A dual-axis servo drive is a device capable of simultaneously controlling two servo motors. It is widely used in industrial automation scenarios requiring multi-axis coordinated motion. A dual-axis servo drive includes a drive 400 and a drive base plate 500. During actual assembly, the drive needs to be mounted on the drive base plate 500. Because the drive 400 has a parallelogram structure, the threaded connection points at its four corners are centrally symmetrical about the longitudinal and lateral axes. This can easily lead to incorrect installation orientation of the drive 400 during assembly, necessitating positioning and guidance. The drive base plate 500 typically has pre-drilled through holes for mounting studs or threaded connections to the drive 400. These through holes also function as positioning holes 700. Since the drive base plate 500 is located below the drive 400, its position must be prioritized according to the assembly sequence to ensure accurate installation of the drive 400.

[0022] To address the assembly problems of the aforementioned dual-axis servo drive, this application proposes an auxiliary device for the dual-axis servo drive, aiming to provide a concept for auxiliary positioning and position guidance for the assembly of the dual-axis servo drive.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] See Figures 1 to 3 As shown, this utility model discloses an auxiliary device for a dual-axis servo drive, comprising: The device body 100 has a mounting platform 100A formed on its surface for receiving the driver base plate; wherein the driver base plate 500 is a plate-shaped structure and its surface is also flat. The mounting platform 100A formed can fit against the surface of the driver base plate 500, reducing the shaking of the driver base plate 500 during the installation of the driver 400 and increasing the stability of the installation process.

[0027] At least two positioning parts 200 are disposed on the main body 100 of the device for positioning the driver base plate on the mounting platform 100A. The positioning parts 200 can be adjusted according to the position and number of mounting positioning holes 700 on the driver base plate 500. The positioning parts 200 can assist in positioning the driver base plate 500 on the mounting platform 100A during the installation process, shorten the calibration time of the driver base plate 500 during the installation process, and ensure the accurate position of the driver base plate 500, reducing the impact of the driver base plate 500's positional deviation on the subsequent installation of the driver 400.

[0028] Preferably, at least two positioning parts 200 can be used to position the driver base plate 500. At the same time, the two positioning parts 200 can be inserted into the mounting positioning holes 700 to limit the driver base plate 500, preventing the driver base plate 500 from shaking or shifting position. Those skilled in the art will understand that the position and number of positioning parts 200 can be adjusted according to the position and number of mounting positioning holes 700, thereby increasing the stability of positioning and limiting the driver base plate 500. The specific adjustment can be made according to the actual positioning requirements and cost.

[0029] At least two guide sections 300 are disposed on the mounting platform 100A to guide the installation direction of the driver. The driver 400 is threadedly connected by threaded connection points on its silicon substrate aligned with threaded connection points on the driver base plate 500. Since the threaded connection points on the driver 400 are symmetrically distributed, incorrect installation is easy during actual installation. The guide sections 300 guide the installation direction of the driver 400, shortening the time spent determining the installation position and direction, improving installation efficiency, and increasing the yield of the assembled dual-axis servo driver. It is worth noting that a dual-axis servo driver needs to control two servo motors separately; therefore, at least two drivers 400 must be installed. Thus, the number of guide sections 300 corresponding to the installation positions of the drivers 400 is at least two. Those skilled in the art will understand that the number of guide sections 300 can be adjusted according to the actual number of drivers 400 installed to ensure that the installation direction is guided for each driver 400.

[0030] In one specific embodiment, the positioning part 200 is a positioning pin 210. At least two positioning pins 210 are engaged in the mounting positioning holes of the driver base plate to limit the driver base plate to be positioned on the mounting platform 100A. The positioning pin 210 is one specific implementation of the positioning part 200. In addition to the positioning pin 210, the positioning part 200 can also be a positioning protrusion, positioning post, or positioning buckle that extends into the mounting positioning hole 700. The positioning pin 210 can also play a limiting role. When the positioning pin 210 extends into the mounting positioning hole 700, the positioning pin 210 will abut against the inner wall of the mounting positioning hole 700. At this time, the positioning pin 210 not only plays a role in assisting in positioning the driver base plate 500, but also can limit the movement of the driver base plate 500 on the mounting platform 100A, reducing the impact of the driver base plate 500's positional deviation on the subsequent installation of the driver 400.

[0031] In an optional embodiment, the positioning part 200 is configured as a group of at least two positioning pins 210. The two positioning pins 210 in each group of positioning parts 200 are symmetrically arranged about the center line of the mounting platform 100A. A single group of positioning parts 200 can realize the positioning of the driver base plate 500 on the mounting platform 100A and limit the positional change of the driver base plate 500 on the mounting platform 100A. The symmetrically arranged positioning pins 210 can not only adapt to the setting of the mounting positioning holes 700 on the driver base plate 500, but also standardize the assembly process of any dual-axis servo driver, thereby shortening the assembly time and improving the assembly efficiency and assembly yield.

[0032] In an optional embodiment, the guide portion 300 includes a column 310 and a stop 320 located at the top of the column 310 and extending horizontally into the mounting platform 100A. The driver 400 has driver pins 600, which are an essential component of the driver 400. Therefore, during the actual installation of the driver 400, if the installation direction and position are incorrect, the stop 320, as a foolproof design, will restrict the driver pins 600, preventing the driver 400 from being properly installed on the driver base plate 500. In this case, the driver 400 needs to be rotated horizontally until the stop 320 no longer restricts the driver. If the actuator pin 600 is correct, then the installation position and direction of the driver 400 are correct. It can be understood that the shape formed by the lines connecting the threaded connection points on the driver 400 is the same as the shape formed by the edge of the driver 400, not an equilateral parallelogram. Therefore, there is a length difference between the lines connecting the threaded connection points, forming a rectangular structure. In actual installation, the only incorrect installation situation of the driver 400 is when the orientation of the driver pin 600 is 180° opposite to the correct installation orientation. The stop 320 on the guide part 300 can avoid this installation error and improve the efficiency and accuracy of installing the driver 400 on the driver base plate 500.

[0033] In an optional embodiment, the guide portion 300 is disposed at intervals along the length direction of the device body 100 at the edge of the device body 100, and the spacing between adjacent guide portions 300 is greater than the width of the driver. It is understood that the driver 400 has different sizes, so the spacing of the guide portions 300 can be adjusted accordingly according to the size difference of the driver 400 to accommodate the installation of any driver 400.

[0034] In an optional embodiment, the two ends of the device body 100 along the length direction are recessed to form gripping portions 110 for grasping the auxiliary device. In actual installation, the installer needs to grasp the auxiliary device for a long time. Therefore, the recessed gripping portions 110 are provided at both ends of the device body 100 to provide gripping points for the installer. During the gripping process, the gripping portions 110 abut against the web of the installer's palm, which facilitates frequent gripping by the installer and improves the assembly efficiency of the dual-axis servo drive.

[0035] In an optional embodiment, the main body 100 of the device is provided with a plurality of hollowed-out portions 120. The hollowed-out portions 120 can reduce the material cost of the main body 100 of the device, and while ensuring the support effect of the main body 100 on the driver base plate 500, they can also reduce the total weight of the auxiliary device, making it easier for installers to handle, thereby improving the assembly efficiency of the dual-axis servo driver.

[0036] In an optional embodiment, the device body 100 and the guide part 300 are fixedly connected and integrally formed. The device body 100 and the guide part 300 can be manufactured by processing a single mold. The integrally formed guide part 300 can have stronger stability, reduce the probability of damage during actual transportation, handling or use, and improve durability.

[0037] In an optional embodiment, the guide part 300 is detachably connected to the device body 100. The detachable connection includes a rail and slot connection, a snap-fit ​​connection, or other detachable connection methods. It is understood that using a detachable connection method can facilitate transportation or on-site handling. Since different drivers 400 have different sizes, in order to adapt to the position of the driver pins 600 on different sized drivers 400, the guide part 300 with the detachable connection method can be adjusted accordingly to limit the driver pins 600 on different sized drivers 400, avoid incorrect installation direction and position of the drivers 400, and improve the assembly efficiency and yield of the dual-axis servo driver.

[0038] The working principle of this utility model is as follows: the mounting platform of the main body of the device supports the driver base plate of the dual-axis servo drive. The positioning part positions the driver base plate on the mounting platform to prevent the driver base plate from shaking or shifting. The guide part guides the driver to be installed in the mounting position and direction on the driver base plate, which can prevent incorrect driver installation. After the driver is fixedly installed to the driver base plate by the threaded parts, other accessory units are assembled. Finally, the driver is unloaded from the auxiliary device to complete the assembly. This effectively improves the assembly efficiency of the dual-axis servo drive and ensures the assembly yield of the dual-axis servo drive.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
