Description

Technical Field

[0001] The utility model relates to the technical field of driving devices, and particularly relates to a servo driver. Background Art

[0002] The correct grounding of a servo driver is a basic safety protection requirement. For traditional grounding, generally, the grounding post of the servo driver is extended out of the housing. However, since the grounding post has an irregular shape and grounding is generally achieved by connecting a grounding screw through a grounding hole, there is a problem of inconvenient hole punching. When processing holes in existing servo drivers, blind holes are generally processed. During drilling, it is difficult to discharge chips and clean residual chips and residual oil, resulting in easy accumulation of residual chips and residual oil in the holes. In addition, since blind hole processing cannot control the hole depth, when the punching depth is too deep, the drill bit is prone to uneven force, resulting in the problem of drill bit breakage, which not only affects the processing efficiency but also increases the processing cost.

[0035] Based on the problems existing in the grounding posts of existing driving devices such as servo drivers, including inconvenient punching, inability to control the punching depth, and uneven force on the drill bit and breakage of the drill bit easily occurring during drilling due to the inability to control the hole depth, the present utility model proposes a servo driver.

[0036] Referring to Figures 1 to 3 , the servo driver includes a housing 20, and a heat dissipation component 10 is arranged inside the housing 20. The heat dissipation component 10 includes a mounting bracket 100 and a grounding post 200. The mounting bracket 100 is used for mounting on the housing. The heat dissipation component 10 is mounted inside the housing of the servo driver through the mounting bracket 100 to reduce the working temperature of the servo driver, achieve heat dissipation, and improve the stability and reliability of the operation of the servo driver.

[0037] In some embodiments of the present utility model, a grounding post 200 is provided on a mounting bracket 100. The grounding post 200 has a connecting section 211 and an opening section 212. An observation port 2111 extending in a first direction is provided at a position of the connecting section 211 adjacent to the opening section 212. The provision of the opening section 212 facilitates drilling. The provision of the observation port 2111 facilitates observing the drilling condition, checking the drilling depth and the material state of the grounding post 200 after drilling, avoiding the influence of drilling quality caused by drilling inclined holes or blind holes, and effectively improving the stability and reliability of grounding. During drilling, when the depth of the connecting hole 2121 reaches a level sufficient to communicate with the observation port 2111, the debris and residual oil in the hole will fall into the observation port 2111 or scatter outside the observation port 2111. The provision of the observation port 2111 also facilitates timely collection and removal of the debris and residual oil generated by drilling, effectively improving the drilling quality.

[0038] A connecting hole 2121 extending in a second direction is provided in the opening section 212. The second direction intersects the first direction. The observation port 2111 is at least partially opposite to the connecting hole 2121 in the second direction. In this way, it can be used to define the drilling depth through the observation port 2111, avoiding situations such as uncontrollable drilling depth, excessive drilling depth resulting in uneven force on the drill bit, and breakage of the drill bit, effectively improving the drilling efficiency and reducing the processing cost.

[0039] The connecting hole 2121 extends in the second direction. The provision of the opening section 212 facilitates drilling. When the servo drive is grounded, it is required that the connecting hole 2121 or the screw for locking the connecting hole 2121 is exposed outside the housing of the servo drive. Therefore, one side surface of the opening section 212 needs to be used as the grounding surface (or drilling surface). Specifically, the side surface of the opening section 212 away from the connecting section 211 is used as the grounding surface (or drilling surface). By drilling one, two or other multiple connecting holes 2121 on the grounding surface, the grounding of the servo drive is achieved. Taking the case where there are two connecting holes 2121 as an example, the two connecting holes 2121 are spaced on the grounding surface of the opening section 212. A grounding hole 21 is provided on the outer surface of the housing 20. The connecting hole 2121 is exposed outside the grounding hole 21 to connect the grounding screw. The position and size of the connecting hole 2121 provided in the opening section 212 correspond to the position and size of the grounding hole 21 on the housing 20. In the installed state, the position of the connecting hole 2121 provided in the opening section 212 is opposite to the position of the grounding hole 21 provided in the housing 20. The connecting hole 2121 is exposed outside the grounding hole 21 and connected to the grounding screw to achieve the safe grounding of the servo drive.

[0040] A connecting hole 2121 extending in a second direction is drilled in the opening section 212, and an observation port 2111 extending in a first direction is provided at a position of the connecting section 211 adjacent to the opening section 212. The second direction intersects the first direction, and at least a part of the observation port 2111 is opposite to the connecting hole 2121 in the second direction, that is, at least a part of the observation port 2111 coincides with the connecting hole 2121. The drilling condition of the connecting hole 2121 can be observed through the side surfaces of the observation port 2111 that are oppositely arranged in the second direction. In some specific embodiments of the present invention, the first direction and the second direction are perpendicularly arranged. Taking Figure 1 the direction indicated by the arrow a as the first direction, and taking Figure 1 the direction indicated by the arrow b as the second direction, the observation port 2111 has a first side surface and a second side surface that are oppositely arranged in the second direction. Taking the side surface of the observation port 2111 close to the opening section 212 as the first side surface, the drilling condition of the connecting hole 2121 can be observed through the first side surface of the observation port 2111 (or through the first side surface and the second side surface of the observation port 2111).

[0041] Compared with the prior art that needs to limit the drilling depth by controlling the drilling speed, controlling the depth of the drill bit penetration, etc., the present invention can limit the drilling depth of the connecting hole 2121 through the arrangement of the observation port 2111. To limit the drilling depth, optionally, specifically, it can be limited that the drilling depth of the connecting hole 2121 is not enough to penetrate the first side surface of the observation port 2111, so as to limit the maximum drilling depth of the connecting hole 2121 through the observation port 2111 and avoid over-drilling. The arrangement of the observation port 2111 can also save materials and reduce costs; or, it can be limited to stop drilling when the connecting hole 2121 penetrates the first side surface of the observation port 2111, so as to reduce the determination process of the drilling depth of the connecting hole 2121. It is not only convenient to observe the drilling state, but also can timely clean the chips and residual oil generated by drilling, improving the drilling quality and drilling efficiency; or, it can be limited to stop drilling after the connecting hole 2121 penetrates the observation port 2111 and penetrates to a specified depth through the second side surface of the observation port 2111, so as to facilitate drilling the connecting hole 2121 with the required depth, and is convenient to observe the drilling state and clean the chips and residual oil generated by drilling, improving the drilling quality and drilling efficiency; specifically, the implementation method of limiting the drilling depth of the connecting hole 2121 through the observation port 2111 can be set according to the actual situation, and by limiting the distance between the first side surface of the observation port 2111 and the grounding surface of the opening section 212, the drilling depth of the connecting hole 2121 can be limited, so as to set the drilling depth to a standard depth or any other depth that meets the actual processing and use requirements; it is not limited here.

[0042] In one embodiment, the observation port 2111 communicates with the connection hole 2121. The setting of the observation port 2111 is used to define the drilling depth. During drilling, the debris and residual oil generated by drilling will fall into the observation port 2111 or scatter outside the observation port 2111. Through the setting of the observation port 2111, it is also convenient to collect and remove the debris and residual oil generated by drilling in a timely manner, effectively improving the drilling quality.

[0043] For the convenience of observing the drilling situation, in one embodiment, the observation port 2111 penetrates through the connection section 211. So as to facilitate observing the opening situation of the connection hole 2121 from different angles of the observation port 2111. Setting the observation port 2111 to penetrate through the connection section 211 can also reduce the use of materials and save costs.

[0044] In one embodiment, the grounding post 200 includes a first connection portion 210. The connection section 211 and the opening section 212 are connected to each other integrally and are configured as the first connection portion 210. The first connection portion 210 has a first surface and a second surface arranged oppositely. The observation port 2111 penetrates at least through the first surface.

[0045] It can be understood that the first connection portion 210 has a first surface and a second surface arranged oppositely along a first direction, and the observation port 2111 penetrates at least through the first surface. Optionally, the observation port 2111 is set to extend from the first surface to the middle of the connection section 211, so that the observation port 2111 is in a groove shape; or, the observation port 2111 is set to penetrate from the first surface to the second surface, so as to set the observation port 2111 as a through hole penetrating from the first surface to the second surface. Setting the observation port 2111 in a groove shape can avoid stress concentration and ensure the stability and reliability of the grounding post 200; setting the observation port 2111 as a through hole can more intuitively observe the opening situation of the connection hole 2121 and reduce the use of materials and save costs.

[0046] On the premise of maintaining the appearance structure of the servo driver and ensuring the strength of the grounding post 200, through the setting of the observation port 2111, it can also effectively solve the problems of difficult determination of drilling depth, easy breakage of the processing drill bit, difficult cleaning of the debris and residual oil generated by drilling, and low drilling efficiency, facilitate drilling processing, effectively simplify the processing procedure, and reduce the processing and manufacturing cost.

[0047] To save materials and reduce the processing and manufacturing cost, in one embodiment, the volume of at least a part of the connection section 211 far from the opening section 212 is smaller than the volume of the opening section 212. It is used to save materials and prevent the opening from being affected due to improper setting of the connection section 211.

[0048] In a specific embodiment, the connecting section has a connecting inclined surface 2112, and the connecting inclined surface 2112 is inclined between the first surface and the second surface, so that the volume of at least part of the connecting section 211 far away from the opening section 212 is smaller than the volume of the opening section 212. Through the arrangement of the connecting inclined surface 2112, it can be used to further define the drilling depth and avoid drilling inclined holes, so as to further optimize the drilling efficiency and quality, and protect the drill bit to avoid breakage and damage caused by uneven force on the drill bit.

[0049] Taking the first side surface as the grounding surface, by drilling a connecting hole 2121 on the grounding surface, the connecting hole 2121 penetrates into the opening section 212, and the connecting hole 2121 passes through the opening section 212 along the second direction and communicates with the observation port 2111, so as to directly view the drilling condition of the opening section 212 through the observation port 2111. Through the arrangement of the connecting inclined surface 2112, the whole first connecting portion 210 can also be in an inverted conical shape, so that the volume of at least part of the connecting section 211 far away from the opening section 212 is smaller than the volume of the opening section 212, which is used to save the use of materials, facilitate processing, and is also convenient for the servo driver to connect wires.

[0050] In an embodiment, the grounding post 200 further includes a second connecting portion 220. The second connecting portion 220 has opposite first and second ends. The first end of the second connecting portion 220 is connected to the first connecting portion 210, and the second end of the second connecting portion 220 is connected to the mounting bracket 100. The grounding post 200 is connected to the mounting bracket 100 of the heat dissipation component 10 through the second connecting portion 220, so as to ensure that the grounding post 200 can be stably arranged on the heat dissipation component 10 and is fixedly connected in the housing 20 through the heat dissipation component 10, making the grounding of the servo driver more stable and reliable.

[0051] The heat dissipation component 10 is arranged in the housing 20 of the servo driver. Due to the limited internal space of the housing 20, generally, the outer diameter of the second connecting portion 220 will be reduced or the occupied space of the second connecting portion 220 will be reduced as much as possible. Through the arrangement of the connecting inclined surface 2112, the pressure can also be dispersed, the overall structural strength can be improved, and the stability of the grounding post 200 can be optimized.

[0052] In an embodiment, the second connecting portion 220 includes a plurality of connecting plates 221 arranged along its circumferential direction, and the first connecting portion 210 is arranged between two adjacent connecting plates 221.

[0053] The second connecting portion 220 is provided as a plurality of connecting plates 221 arranged along its axial direction, which can enhance the structural strength of the terminal, optimize the bearing capacity and stability of the terminal. By arranging a plurality of connecting plates 221 circumferentially, stress concentration can also be reduced, making the terminal more durable and effectively extending its service life. The first connecting portion 210 is disposed between two adjacent connecting plates 221 among them, and is also used to reduce the occupied space of the terminal and ensure the stable connection between the first connecting portion 210 and the second connecting portion 220.

[0054] In some alternative embodiments of the present utility model, the first connecting portion 210 and the second connecting portion 220 are integrally formed structures; or, the first connecting portion 210 and the second connecting portion 220 are separately provided and connected into one body by means of snap connection, bonding, welding, screwing, etc.; specifically, it can be set according to the actual situation and is not limited herein.

[0055] Optionally, to further optimize the connection strength, each connecting plate 221 extends at least from its middle along the circumferential direction of the grounding post 200 towards the second end of the second connecting portion 220 and is used to connect with the mounting bracket 100. The size of the connecting plate 221 near the second end of the second connecting portion 220 is larger than the size of the connecting plate 221 near the first end of the second connecting portion 220. On the one hand, it can optimize the aesthetics, and on the other hand, it can also ensure that the overall structure of the grounding post 200 is more stable, enabling the grounding post 200 to be stably disposed on the mounting bracket 100.

[0056] For the convenience of installation and connection, so that the heat dissipation component 10 can be stably arranged in the housing 20, in one embodiment, the second connecting portion 220 is provided with a mounting portion 222, and the mounting portion 222 and the first connecting portion 210 are arranged away from each other.

[0057] Optionally, the mounting portion 222 can be specifically set as a connecting column or other connecting structures. Taking the connecting column as an example, a hole is provided in the middle of the connecting column. Optionally, the mounting portion 222 is disposed on other sides of the same connecting plate 221 connecting the first connecting portion 210 or between two other adjacent connecting plates 221 of the second connecting portion 220, and is arranged away from the first connecting portion 210.

[0058] It can be understood that the mounting bracket 100 is used to mount the heat dissipation fins of the heat dissipation component 10, and the mounting portion 222 provided on the mounting bracket 100 is used to connect with the main power board arranged in the servo driver housing, or the mounting portion 222 provided on the mounting bracket 100 is used to connect with the electrical components arranged in the servo driver housing. It can also be that the heat dissipation component 10 is used to be fixedly connected to the housing 20 through the mounting portion 222. Specifically, it can be set according to the actual situation, and the function of the mounting portion 222 is not limited herein.

[0059] In addition, it should be noted that, in addition to the aforementioned first connection portion and second connection portion provided on the grounding post, one or more other connection components may be additionally provided on the side of the mounting bracket 100 where the grounding post 200 is provided. The connection component has opposite first and second ends.
