Description

Technical Field

[0001] The utility model relates to the technical field of servo drivers, in particular to an AC servo driver which is easy to fix. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] There are two common installation methods for servo drives: horizontal installation and vertical installation. Choose the corresponding installation method according to the needs of different situations. Horizontal installation means placing the servo drive flat on a bracket or mounting plate. Therefore, when installed horizontally, the contact area between the servo drive and the bracket or mounting plate will be larger than the contact area when installed vertically, which is not conducive to the heat dissipation of the servo drive. Therefore, how to facilitate the heat dissipation of the servo drive is a problem to be solved. And because the servo drive also needs to be fixed when installed horizontally, it is mostly fixed around the four sides with screws. However, the servo drive needs to be disassembled during maintenance, but because the wiring terminals of the servo drive are connected to the circuit and are installed horizontally, the screws are not easy to be disassembled. Sometimes it is necessary to remove the circuit at the wiring terminal before disassembling the servo drive. Therefore, how to facilitate the disassembly of the servo drive is a problem to be solved.

[0004] For a servo drive, the servo drive needs to be fixed during use, and how to provide stable fixation for the servo drive while facilitating its disassembly is a problem to be solved. Currently, screws are usually used for fixing, but the operation of fixing the servo drive with multiple screws is cumbersome, so that the staff needs to spend a lot of time to remove all the screws around the servo drive. Therefore, how to facilitate the removal and installation of the servo drive is a problem to be solved. Utility Model Content

[0005] The purpose of the utility model is to provide an AC servo drive device that is easy to fix. The device fixes the partition plate through a connecting piece and a clamping seat, thereby providing support and fixing for the servo drive. The connecting piece is easy to disassemble, so that the servo drive can be quickly disassembled during maintenance. There is a gap between the top of the clamping seat of the device and the side plate of the servo drive, so that the heat generated by the servo drive during operation can be dissipated as quickly as possible.

[0006] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0007] An AC servo drive device that is easy to fix includes a servo drive and a support device; a plurality of partitioning splints are arranged in an array on one side panel of the servo drive; the support device includes a base and a clamping seat, the base is connected to the clamping seat, a gap that matches the partitioning splint is provided on the clamping seat, the gap contacts the partitioning splint, and there is a gap between the top of the clamping seat and the side panel of the servo drive. The clamping seat is provided with a gap that matches the partitioning splint, so that the clamping seat can fix the partitioning splint, and the gap depth on the clamping seat is less than the length of the partitioning splint, so that when one side of the partitioning splint contacts the bottom of the gap of the clamping seat, there is a gap between the top of the clamping seat and the side panel of the servo drive. If there is no gap so that the top of the clamping seat contacts the side panel of the servo drive, local overheating will occur during long-term use, affecting the normal operation of the servo drive and other problems.

[0008] The partitioning splint is provided with a first through hole, the clamping seat is provided with a second through hole adapted to the first through hole, and a connecting piece is provided at the connection between the first through hole and the second through hole, and the connecting piece penetrates the first through hole and the second through hole, and is connected in a limited position. The servo drive can be fixed by the contact between the partitioning splint and the gap on the clamping seat, but due to the vibration and other problems that may exist in the installation environment of the device, under long-term vibration, the partitioning splint and the clamping seat may become loose, or the servo drive may become loose during multiple disassembly, maintenance, and installation, so a first through hole is provided on the partitioning splint, and a second through hole with the same size, shape, and position as the first through hole is provided on the clamping seat, and a connecting piece is provided at the connection between the second through hole and the first through hole, and the function of the connecting piece is to connect the partitioning splint and the clamping seat in a limited position, so as to reduce the relative movement between the clamping seat and the partitioning splint. The end of the partitioning splint away from the servo drive contacts the bottom of the gap, and the clamping seat supports the servo drive. The array of heat dissipation mesh holes is arranged on one side of the multiple partitioning clamps near the servo driver, and the heat dissipation mesh holes are located in the spacing between the clamping seat and the servo driver. The heat dissipation mesh holes facilitate the heat dissipation of the servo driver during operation, because the horizontally installed servo driver has a large area in contact with the ground or machinery during installation. During long-term operation, the heat here will accumulate. Therefore, the heat dissipation mesh holes are arranged to facilitate the heat dissipation.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The device fixes the partitioning plate through the connecting parts and the clamping seat, so as to provide support and fixation for the servo drive, and the convenient disassembly of the connecting parts enables the servo drive to be quickly disassembled during maintenance. There is a gap between the top of the clamping seat of the device and the side plate of the servo drive, so that the heat generated by the servo drive during operation can be dissipated as quickly as possible.

[0017] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0018] The utility model is an AC servo drive device that is easy to fix. The main structure includes a servo drive 1 and a support device 2. A plurality of partitioning plywoods 3 are arranged in an array on a side plate of the servo drive 1. The partitioning plywoods 3 are integrally arranged with the side plate of the servo drive 1. When the housing of the servo drive 1 is installed, a side plate with a plurality of partitioning plywoods 3 is selected, so that the servo drive 1 can be fixed. And the same servo drive 1 can select one side or both sides to install the side plate with the partitioning plywoods 3. So it is convenient to fix the servo drive 1 later. The partitioning plywood 3 is provided with a first through hole 8 (described in detail below) and a heat dissipation mesh 11. The function of the first through hole 8 is to facilitate the fixing of the servo drive 1. The heat dissipation mesh 11 is convenient for the heat dissipation of the servo drive 1 during operation, because the horizontally installed servo drive 1 has a large area in contact with the ground or the machine during installation. During a long period of operation, the heat here will be accumulated. Therefore, the heat dissipation mesh 11 is provided to facilitate the heat dissipation.

[0019] The support device 2 includes a base 4 and a clamping seat 5, and the clamping seat 5 is fixedly connected to the base 4. The base 4 is in contact with the ground or the mounting surface of the machine. When the servo driver 1 needs to be disassembled for subsequent maintenance, it is only necessary to disassemble the servo driver 1 and the support device 2, without removing the screws one by one. The base 4 allows the servo driver 1 to be fixed indirectly. The clamping seat 5 is provided with a gap 6 that is compatible with the partitioning clamp 3, so that the clamping seat 5 can fix the partitioning clamp 3, and the depth of the gap 6 on the clamping seat 5 is less than the length of the partitioning clamp 3, so that one side of the partitioning clamp 3 is in contact with the bottom of the gap 6 of the clamping seat 5, and there is a gap 7 between the top of the clamping seat 5 and the side plate of the servo driver 1. If there is no gap 7, the top of the clamping seat 5 is in contact with the side plate of the servo driver 1, which will cause local overheating during long-term use, affecting the normal operation of the servo driver 1. The existence of the gap 7 allows the heat to be dissipated, so that it can also be used in some environments with higher temperatures. In order to achieve better heat dissipation, the heat dissipation mesh 11 arranged on the partition clamp 3 is located within the interval 7 between the clamping seat 5 and the servo driver 1, so that the heat dissipation of the servo driver 1 within the interval 7 is not limited to the heat loss caused by air circulation in a single direction.

[0020] The size of the gap 6 on the clamping seat 5 and the size of the partitioning clamping plate 3 should be roughly the same, that is, the servo drive 1 can be fixed by contacting the gap 6 between the partitioning clamping plate 3 and the clamping seat 5, but due to the installation environment of the device, there may be vibration and other problems. Under long-term vibration, the partitioning clamping plate 3 and the clamping seat 5 may become loose, or the servo drive 1 may become loose during multiple disassembly, maintenance, and installation. Therefore, a first through hole 8 is provided on the partitioning clamping plate 3, and a second through hole 9 is provided on the clamping seat 5. The second through hole 9 is provided with a connecting piece 10 at the connection with the first through hole 8. The function of the connecting piece 10 is to limit the connection between the partitioning clamping plate 3 and the clamping seat 5, and reduce the relative movement between the clamping seat 5 and the partitioning clamping plate 3. The connecting piece 10 is set in a triangle shape to increase the plane contact area between the connecting piece 10 and the first through hole 8 and the second through hole 9, and increase the friction force. Prevent the displacement of the connecting piece 10, etc.

[0021] Detailed instructions for use:

[0022] Install the side panel with the partitioning plywood 3 onto the servo driver 1, then install the support device 2 to the position where the servo driver 1 is to be installed, and then fix the support device 2. Then connect the partitioning plywood 3 on the servo driver 1 with the gap 6 on the clamping seat 5, so that the clamping seat 5 and the servo driver 1 provide a support function, and because the depth of the gap 6 is less than the height of the partitioning plywood 3, there is a spacing 7 between the top of the clamping seat 5 and the side wall of the servo driver 1, so that the servo driver 1 can dissipate heat. Finally, the connector 10 is passed through the first through hole 8 and the second through hole 9, so that the connector 10 can limit and fix the connection between the servo driver 1 and the support device 2.

[0023] In summary, the device fixes the partition plate 3 through the connecting piece 10 and the clamping seat 5, thereby providing support and fixation for the servo driver 1, and the convenient disassembly of the connecting piece 10 allows the servo driver 1 to be quickly disassembled during maintenance. There is a gap 7 between the top of the clamping seat 5 of the device and the side plate of the servo driver 1, so that the heat generated by the servo driver 1 during operation can be dissipated as quickly as possible.
