[0002] The protective power supply for servo drive is a power supply device specially designed to protect servo drive. Its main function is to provide a stable power supply for the servo system and protect the servo drive from damage when abnormal conditions occur in the power grid (such as overvoltage, undervoltage or short circuit). The protective power supply usually has functions such as voltage regulation and overvoltage protection.

[0003] The traditional installation method between the protective power supply for servo drives and the mounting base is to use bolt connection. In actual use, due to the different reserved positions of the bolt holes, the bolt connection method requires the bolt hole positions and sizes of the mounting base and the protective power supply for servo drives to be unified to ensure the matching of the installation. This method limits the flexibility and adaptability of the installation during use; at the same time, the bolt-type installation method requires the use of tools such as wrenches or wrench sockets during disassembly and assembly, which makes the disassembly and installation process relatively cumbersome and requires additional operation adjustment time, especially when the installation position of the protective power supply for servo drives is limited or difficult to reach, it becomes more difficult to use tools for disassembly and positioning, and after the installation of the protective power supply for servo drives is completed, its installation position cannot be fine-tuned and changed; and the existing protective power supply for servo drives lacks heat dissipation treatment for the protective power supply on its mounting base. Therefore, a protective power supply for servo drives is proposed to solve the above problems. Utility Model Content

[0009] The two groups of protection power supply mounting brackets each include a bracket plate arranged below the protection power supply outer shell, two linear guide rails are installed on the bracket plate, and two guide rail sliders are slidably arranged on the two linear guide rails;

[0010] The four guide rail slide blocks in the two groups of protection power supply mounting brackets are vertically supported by limit columns;

[0011] The protection power supply heat dissipation component comprises a bottom mounting seat arranged between two groups of protection power supply mounting brackets, and two groups of heat dissipation fans are installed on the bottom mounting seat.

[0012] As a further improvement of the present invention, the four limiting grooves are all open and respectively correspond to one of the guide rail sliders and are arranged adjacent to it; the limiting columns are fitted in an adjacent limiting groove.

[0013] As a further improvement of the utility model, a threaded sleeve is integrally installed on each guide rail slider, an internal threaded hole is penetrated in the threaded sleeve and a positioning bolt is threadedly connected, and the end of the positioning bolt penetrates the threaded sleeve and extends to abut against the side wall of the linear guide rail.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] Depend on Figure 1-3Provided is a protective power supply for a servo drive, comprising a protective power supply body 3 for a servo drive;

[0027] The outer bottom of the servo drive protection power supply body 3 is equipped with a protection power supply outer shell 31; two sides of the protection power supply outer shell 31 are provided with two limit grooves 32;

[0028] The invention also includes two sets of protective power supply mounting brackets 1; the two sets of protective power supply mounting brackets 1 are arranged at the bottom of the protective power supply outer shell 31 and support the protective power supply outer shell 31;

[0029] A protective power supply heat dissipation component 2 is installed between the two sets of protective power supply mounting brackets 1;

[0030] The two sets of protection power supply mounting brackets 1 each include a bracket plate 11 disposed below the protection power supply outer shell 31, two linear guide rails 12 are mounted on the bracket plate 11, and two guide rail sliders 13 are slidably disposed on the two linear guide rails 12;

[0031] The four guide rail sliders 13 in the two sets of protection power supply mounting brackets 1 are vertically supported by limit posts 16;

[0032] The protective power supply heat dissipation component 2 comprises a bottom mounting seat 21 arranged between two groups of protective power supply mounting brackets 1 , and two groups of heat dissipation fans 23 are installed on the bottom mounting seat 21 .

[0033] In the present embodiment, in actual use, the protective power supply outer shell 31 is clamped and installed by two sets of protective power supply mounting brackets 1 of the present application, so that the protective power supply outer shell 31 can be quickly installed on the two sets of protective power supply mounting brackets 1, thereby realizing the clamping installation of the protective power supply body 3 for the servo drive; compared with the traditional bolt-type installation method, the protective power supply mounting bracket 1 of the present application can be clamped and installed on the protective power supply body 3 for servo drives of different sizes, and no complex tools are required during installation, and no bolt holes need to be reserved in the installation environment to complete the installation and disassembly of the protective power supply body 3 for the servo drive, which simplifies the maintenance process and reduces the difficulty and cost of operation.

[0034] Furthermore, by disposing the protective power supply heat dissipation component 2 between the two groups of protective power supply mounting brackets 1, the multiple groups of cooling fans 23 disposed in the protective power supply heat dissipation component 2 can always perform air-cooling on the protective power supply body 3 for the servo drive and the protective power supply outer shell 31, thereby avoiding the protective power supply body 3 for the servo drive from generating a large amount of heat during use that affects the safety of use, and making the installation of the protective power supply body 3 for the servo drive more stable.

[0035] Specifically, refer to Figure 1-3The four limiting grooves 32 are all open and correspond to one of the guide rail sliders 13 and are arranged adjacent to it; the limiting column 16 is fitted and matched with the adjacent limiting groove 32.

[0036] In this embodiment, in actual use, the user can place the protective power supply outer shell 31 on the upper end surface of the two sets of protective power supply mounting brackets 1 and make it supported on the four guide rail sliders 13. At this time, the user slides the four guide rail sliders 13 and makes the limiting columns 16 set on the guide rail sliders 13 embedded in the limiting grooves 32 in turn. At this time, due to the interlocking limitation of the limiting columns 16 and the positioning of the guide rail sliders 13, the protective power supply outer shell 31 can be stably installed between the four guide rail sliders 13, thereby achieving stable installation on the two sets of protective power supply mounting brackets 1.

[0037] Specifically, refer to Figure 2-3 A threaded sleeve 14 is integrally mounted on each guide rail slider 13 , and an internal threaded hole is formed in the threaded sleeve 14 and is threadedly connected with a positioning bolt 15 . The end of the positioning bolt 15 passes through the threaded sleeve 14 and extends to abut against the side wall of the linear guide rail 12 .

[0038] In this embodiment, the user loosens the positioning bolt 15 on the guide rail slider 13, and the positioning bolt 15 will move in the threaded sleeve 14, thereby gradually moving away from the tight contact with the linear guide rail 12, so that the guide rail slider 13 can slide freely on the linear guide rail 12.

[0039] Furthermore, the user slides the guide rail slider 13 until the limiting posts 16 on the four guide rail sliders 13 are sequentially embedded in the limiting grooves 32 , and then the user tightens the positioning bolts 15 again, so that the guide rail slider 13 can be positioned on the linear guide rail 12 .

[0040] Furthermore, the four guide rail sliders 13 arranged in the protective power supply mounting bracket 1 can be freely adjusted in position, so that the installation position of the protective power supply body 3 for the servo drive can be freely adjusted. Compared with the traditional matching installation of the reserved position of the bolt hole and the bolt hole, the protective power supply body 3 for the servo drive of the present application can adjust the installation position more flexibly, which helps to optimize the installation layout according to actual needs, thereby further improving the scope of use.

[0041] Specifically, refer to Figure 2-3 The limiting column 16 on each guide rail slider 13 supports a clamping block 17, and a rubber block 18 is installed on the clamping block 17; 19 is opened on the two bracket plates 11.

[0042] In this embodiment, when the protective power supply outer shell 31 is installed on the guide rail slider 13, the clamping block 17 provided at this time can cooperate with the rubber block 18 to achieve the clamping limit of the protective power supply outer shell 31. The provided rubber block 18 can further increase the clamping friction force on the protective power supply outer shell 31, thereby preventing the protective power supply outer shell 31 from sliding; and the provided 19 can be used to install bolts, thereby achieving the stable installation of the two sets of protective power supply mounting brackets 1 in the use environment.

[0043] Specifically, refer to Figure 2 Dust filter covers 22 are installed outside the two cooling fans 23.

[0044] In this embodiment, the user connects the power supply to the two sets of cooling fans 23 so that the cooling fans 23 can always perform air-cooling on the protective power supply housing 31 and the protective power supply body 3 for the servo driver, so that the protective power supply body 3 for the servo driver can always be in a suitable temperature environment during operation, thereby avoiding high-temperature damage. The dust filter cover 22 can be used to shield and protect the cooling fan 23 to prevent external impurities from causing damage to the cooling fan 23.

[0045] The utility model provides a protective power supply for the servo drive:

[0046] Step 1: In actual use, when the user needs to install the protective power supply body 3 for the servo drive, first place the protective power supply housing 31 on the upper end surfaces of the two sets of protective power supply mounting brackets 1 and make it supported on the four guide rail sliders 13. At this time, the protective power supply housing 31 set will be placed between the four rubber blocks 18 and fit with them. The user loosens the positioning bolts 15 on the guide rail slider 13. At this time, the positioning bolts 15 will move in the threaded sleeve 14, thereby gradually moving away from the tight contact with the linear guide 12, so that the guide rail slider 13 can slide freely on the linear guide 12. The user slides the guide rail slider 13 until the limiting columns 16 on the four guide rail sliders 13 are embedded in the limiting grooves 32 in turn. At this time, the user tightens the positioning bolts 15 again, so that the guide rail slider 13 can be positioned on the linear guide 12. Due to the interlocking limitation of the limiting columns 16 and the positioning of the guide rail slider 13, the protective power supply housing 31 can be stably installed between the four guide rail sliders 13, thereby achieving stable installation on the two sets of protective power supply mounting brackets 1;

[0047] Step 2: The user connects the two sets of cooling fans 23 to a power source so that the cooling fans 23 can always perform air-cooling on the protective power supply housing 31 and the protective power supply body 3 for the servo drive, so that the protective power supply body 3 for the servo drive can always be in a suitable temperature environment during operation, thereby avoiding high-temperature damage.

[0048] The embodiments of the present invention have been shown and described. It will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
