Description

Technical Field

[0001] This utility model relates to the field of DC servo driver technology, specifically a DC servo driver. Background Technology

[0002] A DC servo drive is a controller used to control a DC servo motor, similar to a frequency converter for an AC motor. It is part of a servo system. Traditional DC drives typically use at least four screws to secure the housing, with the circuit board fixed to one side. Disassembly for maintenance is cumbersome, and the limited space and inconvenience during installation or removal can easily damage internal components, affecting the device's normal operation and lifespan. Furthermore, traditional DC drives have limited heat dissipation, leading to overheating and reduced performance over time. Therefore, there is an urgent need for a DC servo drive that is easy to install and disassemble and has strong heat dissipation capabilities. Summary of the Invention

[0004] To achieve the above objectives, this utility model provides the following technical solution: a DC servo driver, comprising an interface panel with an interface and a control panel, and a housing. A reinforcing limiting frame is fixedly installed on one side of the interface panel, and the housing is disposed outside the reinforcing limiting frame. Heat dissipation plates with cooling fans are fixedly installed on both parallel side plates of the housing. A conductive cylinder is embedded in the side plate of the housing. An insulating layer is provided at the contact point between the conductive cylinder and the interface panel. A terminal is provided at one end of the conductive cylinder for connecting to the positive and negative wires of the cooling fan on the heat dissipation plate. The insulating layer can effectively prevent short circuits between the conductive cylinder and the interface panel, ensuring the safe operation of the equipment.

[0005] Preferably, a conductive post is provided on one side of the interface panel. The conductive post is electrically connected to the circuit module, and an insulating layer is provided at the contact point between the conductive post and the interface panel. After the housing and the interface panel are fixed, the corresponding conductive post is inserted into the conductive cylinder.

[0006] Preferably, the top and bottom surfaces of the reinforced limiting frame are provided with limiting grooves, and the bottom surface of the top plate and the top surface of the bottom plate of the housing are fixedly connected with limiting strips that are adapted to the limiting grooves.

[0007] Preferably, the side plate of the reinforcing limiting frame away from the interface panel has a threaded hole, and the side plate of the housing away from the interface panel has a through hole. It also includes a fixing bolt, one end of which passes through the through hole in the side plate of the housing and is threaded into the threaded hole. The housing and the reinforcing limiting frame can be fixed together using a single fixing bolt, greatly simplifying the installation and disassembly process.

[0008] Preferably, the top and bottom plates of the housing, as well as the two side plates on which the heat sink is mounted, are provided with heat dissipation areas. One heat dissipation area on the two side plates on which the heat sink is mounted is located on the upper part of the heat sink, and the other is located on the lower part of the heat sink. The area on the two side plates on which the heat sink is mounted has a hollow structure. The heat sink is provided with heat dissipation fins and heat sink fan mounting positions. The heat sink fan mounting position area has a hollow structure. The heat sink fan is connected to the terminal of the conductive cylinder through a wire. This heat dissipation structure design enables the heat sink fan on the heat sink to promote air convection inside the housing when it is working, thereby accelerating heat dissipation and improving the heat dissipation capacity of the device.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model features an ingenious structure. A reinforced limiting frame restricts the housing's position, effectively preventing damage to the circuit modules during installation and removal, thus protecting internal components. The device can be secured with only a single bolt, significantly simplifying installation and disassembly compared to traditional methods using multiple screws, thereby improving maintenance efficiency. Heat dissipation plates are located on both sides of the housing, working in conjunction with heat dissipation zones on the side plates to accelerate heat dissipation, effectively enhancing the device's heat dissipation capacity, ensuring stable operation within the normal temperature range, and extending the device's lifespan.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 6 This utility model provides a technical solution: a DC servo driver, including an interface panel 1 with an interface and a control panel, and a housing 2. A reinforcing limiting frame 6 is fixedly installed on one side of the interface panel 1, and the housing 2 is disposed outside the reinforcing limiting frame 6. This structural design makes the installation and disassembly of the housing 2 and the interface panel 1 more convenient. During installation and disassembly, the reinforcing limiting frame 6 can limit the housing 2, preventing it from directly contacting the internal circuit modules and preventing damage to components from impacts.

[0022] Furthermore, heat dissipation plates 3 with cooling fans are fixedly installed on both parallel side plates of the housing 2. Conductive cylinders 201 are embedded in the side plates of the housing 2. An insulating layer is provided at the contact point between the conductive cylinder 201 and the interface panel 1. One end of the conductive cylinder 201 is provided with a terminal for connecting to the positive and negative wires of the cooling fans on the heat dissipation plate 3. The insulating layer effectively prevents short circuits between the conductive cylinder 201 and the interface panel 1, ensuring the safe operation of the equipment.

[0023] Furthermore, a conductive post 101 is provided on one side of the interface panel 1. The conductive post 101 is electrically connected to the circuit module 5. An insulating layer is provided at the contact point between the conductive post 101 and the interface panel 1. After the housing 2 is fixed to the interface panel 1, the conductive post 101 is inserted into the conductive cylinder 201. This conductive connection method is simple and reliable, and is easy to install and disassemble.

[0024] Furthermore, limiting grooves 601 are provided on both the top and bottom surfaces of the reinforcing limiting frame 6. Limiting strips 202, which are adapted to the limiting grooves 601, are fixedly connected to the bottom surface of the top plate and the top surface of the bottom plate of the housing 2. The limiting strips 202 are slidably disposed within the limiting grooves 601. The cooperation between the limiting strips 202 and the limiting grooves 601 allows the housing 2 to move along a fixed trajectory during installation and disassembly, further improving the convenience of installation and disassembly, and also enhancing the stability of the connection between the housing 2 and the interface panel 1.

[0025] Furthermore, the side plate of the reinforcing limiting frame 6 away from the interface panel 1 has a threaded hole 602, and the side plate of the housing 2 away from the interface panel 1 has a through hole. It also includes a fixing bolt 7, one end of which passes through the through hole in the side plate of the housing 2 and is threaded into the threaded hole 602. The housing 2 and the reinforcing limiting frame 6 can be fixed together using only one fixing bolt 7, greatly simplifying the installation and disassembly steps.

[0026] Furthermore, heat dissipation areas 203 are provided on the top and bottom plates of the housing 2, as well as on the two side plates on which the heat dissipation plate 3 is mounted. One heat dissipation area 203 on the two side plates on the housing 2 is located on the upper part of the heat dissipation plate 3, and the other is located on the lower part of the heat dissipation plate 3. The area on the two side plates on the housing 2 where the heat dissipation plate 3 is mounted has a hollow structure. This heat dissipation structure design allows the cooling fan on the heat dissipation plate 3 to promote vertical air convection inside the housing 2 when it is working, thereby accelerating heat dissipation and improving the heat dissipation capacity of the device.

[0027] Furthermore, a handle is provided on the top of the top plate of the shell 2 for easy handling of the equipment; rubber feet are provided at the corners of the bottom surface of the bottom plate of the shell 2 to provide shock absorption and stable placement.

[0028] Furthermore, a circuit module mounting plate 4 is fixedly connected to one side of the interface panel 1 where the reinforcing limit frame 6 is installed. A circuit module 5 is installed on one side of the circuit module mounting plate 4. The circuit module 5 is the same as the circuit module of the existing DC driver and is prior art. This application will not elaborate further. The middle part of the circuit module mounting plate 4 has a hollow structure to facilitate heat dissipation. The conductive post 101 is electrically connected to the power supply unit of the circuit module 5.

[0029] The working process of this utility model is as follows:

[0030] like Figure 1 - Figure 4As shown, during the installation of the DC servo driver, the limiting strip 202 on the housing 2 can slide accurately along the limiting groove 601 on the reinforced limiting frame 6, thereby ensuring that the housing 2 can smoothly and accurately dock with the interface panel 1, avoiding unnecessary collisions between the housing 2 and the internal circuit module 5 during installation. When maintenance is required and the housing 2 is removed, the limiting groove 601 and the limiting strip 202 also guide the housing 2 to move smoothly along a predetermined trajectory, minimizing the risk of collisions with the circuit module 5. Only one fixing bolt 7 is used to fix the housing 2 to the reinforced limiting frame 6, greatly facilitating the disassembly and assembly of the device and making subsequent maintenance easier. Cooling fans are fixedly installed on both parallel side plates of the housing 2. The heat sink 3 has heat dissipation areas 203 on the top plate, bottom plate, and side plates of the housing 2. The heat dissipation areas 203 on the side plates of the housing 2 are located at the upper and lower parts of the heat sink 3, respectively. When the driver is working, the cooling fan on the heat sink 3 starts to operate, and the generated air force causes air to enter the housing 2 from the heat dissipation area 203 at the lower part of the heat sink 3. This design enhances the air convection effect, so that the heat inside the driver can be dissipated quickly and effectively, which significantly improves the heat dissipation capacity of the device and ensures the stability and reliability of the driver during long-term operation. At the same time, the design of the conductive cylinder 201 and the conductive post 101 avoids the need for frequent disassembly and rewiring of the cooling fan during maintenance, which is beneficial to the maintenance of the driver.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
