[0002] Figure 1 A structural diagram of a plate-type resistor for installation is shown.

[0003] like Figure 1 As mentioned above, the plate resistor is composed of three wound resistors wound on a mica board, and the three mica board wound resistors are fastened by four sets of small aluminum tubes plus bolts and nuts. The traditional assembly method is that workers tighten them in the order of diagonals. However, during the assembly process, it was found that after the four sets of bolts were tightened, the two bottom surfaces of the plate resistor bracket would not be on the same plane. That is, when the plate resistor is placed on a plane and shaken, it will shake up and down, that is, the entire plate resistor is twisted in the side view direction. This situation will cause the following problems:

[0004] 1) Poor visual appearance 2) May cause foot size deviation and affect installation 3) Even if it does not affect installation, it will cause long-term stress on the plate-type resistor body, which is not conducive to structural stability. Utility Model Content

[0025] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model is further described in detail with examples below.

[0026] Figure 2 A schematic diagram of the structure of a plate-type resistor assembly tool in an unassembled state according to an embodiment of the utility model is shown;

[0027] like Figure 2 As shown, according to an embodiment of the utility model, a plate-type resistor assembly tool 200 includes a horizontally arranged fixed base plate 1, and also includes a first column 11 and a second column 12 which are relatively arranged and vertically arranged on the fixed base plate 1, and the first column 11 is provided with a first slider 21 which can slide up and down along the first column 11, and a first pressure plate 31 is horizontally extended from the top of the first slider 21; the second column 12 is provided with a second slider 22 which can slide up and down along the second column 12, and a second pressure plate 32 is horizontally extended from the top of the second slider 22; the first slider 21 is also provided with a first fixing mechanism, and the first fixing mechanism is configured to fix the first slider 21 on the first column 11; the second slider 22 is also provided with a second fixing mechanism, and the second fixing mechanism is configured to fix the second slider 22 on the second column 12.

[0028] Based on this embodiment, the first column 11 and the second column 12 can be fixed to the fixed base plate 1 by fasteners such as bolts and nuts, and the first slider 21 and the second slider 22 can move up and down along the second column 12; the tops of the first slider 21 and the second slider 22 are respectively horizontally extended with the first pressing plate 31 and the second pressing plate 32, which are used to press the upper top foot of the plate-type resistor 100 downward to a horizontal state; the first pressing plate 31 and the first slider 21 can be integrally arranged or additionally connected by a fixing member; the second pressing plate 32 and the second slider 22 can also have the same structure.

[0029] Furthermore, a first slide rail 41 adapted to the first slider 21 is disposed on the first column 11 ; and a second slide rail adapted to the second slider 22 is disposed on the second column 12 .

[0030] Based on this embodiment, by providing a first slide rail 41 corresponding to the first slider 21 on the first column 11, and providing a second slide rail corresponding to the second slider 22 on the second column 12, the first slider 21 and the second slider 22 can slide up and down along the first slide rail 41 and the second slide rail respectively, so as to slide the first pressing plate 31 and the second pressing plate 32 to the expected position, so as to contact and press the upper pin of the plate-type resistor 100. The first slide rail 41 and the second slide rail can be installed on the first column 11 and the second column 12 respectively by fasteners such as bolts and nuts.

[0031] Further, based on the above embodiments, the first fixing mechanism includes a first handle and a first fastener, the first fastener is inserted into the first slider 21 and can be pressed against the first track or moved away from the first track as the first handle rotates; and the second fixing mechanism includes a second handle and a second fastener, the second fastener is inserted into the second slider 22 and can be pressed against the second track or moved away from the second track as the second handle rotates.

[0032] Specifically, the first fastener is horizontally arranged on the first side of the first slider 21, and the first handle is rotatably mounted on the first fastener. When the first handle is rotated in a certain direction (e.g., clockwise), the first fastener can rotate accordingly, and its end away from the first handle approaches the surface of the first side of the first track facing the first slider 21, and then abuts against the surface of the first track to fix the first slider 21. Conversely, when the first handle is rotated in the opposite direction (e.g., counterclockwise), the first fastener can rotate accordingly, and its end away from the first handle moves away from the surface of the first track, so that the first slider 21 can move again; the structure and principle of the second fastener and the second handle are the same as those of the first fastener and the first handle, and are not described in detail here. Among them, the first fastener and the second fastener can be bolts integrally connected to the first handle and the second handle respectively.

[0033] Furthermore, the first pressing plate 31 is provided with a first positioning column 51 corresponding to the upper pin hole of the plate-type resistor, and the second pressing plate 32 is provided with a second positioning column corresponding to the upper pin hole of the plate-type resistor.

[0034] By providing the first positioning column 51 and the second positioning column on the lower surface of the first pressing plate 31 and the second pressing plate 32 , the first positioning column 51 and the second positioning column can pass through the upper pin hole of the plate-type resistor, so that the plate-type resistor is more stable during the process of being fixed and pressed down.

[0035] Furthermore, a first limiting plate 61 is disposed on the top of the first column 11 , and a second limiting plate 62 is disposed on the top of the second column 12 .

[0036] Based on this embodiment, the first limiting plate 61 and the second limiting plate 62 are provided so that the first sliding block 21 and the second sliding block 22 will not deviate from the first track and the second track when sliding upward along the first column 11 and the second column 12 .

[0037] Furthermore, a group of positioning pins 70 are provided on the fixed base plate 1 , and the distribution and size of the group of positioning pins 70 correspond to the distribution and size of the foot holes on the foot 103 of a model of the plate-type resistor.

[0038] By setting a group of positioning pins 70 on the fixed base plate 1, the positioning pins 70 can be inserted into the foot holes of the foot 103 on the plate-type resistor to better position the plate-type resistor. It should be noted that the number of positioning pins 70 is not necessarily completely consistent with the number of foot holes of the plate-type resistor of this type. For example, when the foot holes are distributed as two on one side of the first column 11 and two on one side of the second column 12, the positioning pin 70 can be one of the two foot holes corresponding to the first column 11 and one of the two foot holes corresponding to the second column 12.

[0039] Furthermore, the first column 11 and the second column 12 are respectively detachably mounted on the fixed base plate 1 .

[0040] Specifically, the first column 11 and the second column 12 can be respectively set to an L shape, with mounting holes opened on the horizontal plate, and corresponding mounting holes are also provided on the fixed base plate 1. The first column 11 or the second column 12 is fixed to the fixed base plate 1 by fasteners passing through the mounting holes of the two.

[0041] Based on the above embodiments, further, two or more groups of the positioning pins 70 are arranged on the fixed base plate 1, wherein the distribution and size of the positioning pins 70 of different groups correspond to the distribution and size of the foot holes of the plate-type resistors of different models.

[0042] Two or more groups of positioning pins 70 are provided on the fixed base plate 1, so as to adapt to different types of plate-type resistors; combined with the detachable structure of the first column 11 and the second column 12, different types of plate-type resistors can be adaptively assembled.

[0043] Furthermore, the assembly tool is suitable for a plate-type resistor located on a converter power interface module.

[0044] Figure 3 A schematic structural diagram of a plate-type resistor assembly tool 200 in an assembled state according to an embodiment of the utility model is shown;

[0045] Combination Figure 3 The assembly method of the assembly tool of the embodiment of the utility model is briefly described. First, the semi-finished product with the aluminum tube 101 and the bolts inserted is placed into the positioning pin 70 on the fixed bottom plate 1 according to the bottom foot hole position, and then the plate-type resistor is pressed down with force to make the bottom feet on both sides contact with the fixed bottom plate 1 absolutely horizontally, and the downward pressure is maintained, and the first slider 21 and the second slider 22 are slid until the first pressing plate 31 and the second pressing plate 32 fully contact the two upper feet of the plate-type resistor, and then the first handle and the second handle are rotated to make the first slider 21 and the second slider 22 completely tightened, so as to ensure that the bottom feet of the semi-finished plate-type resistor remain horizontal during the tightening of the screw and the overall posture will not be twisted or deformed.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
