Description

Technical Field

[0001] The utility model belongs to the technical field of transformers, and in particular relates to a transformer core assembly workbench. Background Art

[0002] When assembling the transformer, it is composed of an iron core and channel steels that clamp the iron core on both sides. During assembly, it is also necessary to use limit bolts to pass through the limit channels on the iron core to limit the iron core, and then use tension bolts to continue bolting the ends of the two sets of channel steels.

[0003] The iron core is made of multiple stacked silicon steel sheets, which are provided with fixing holes to ensure that the multiple silicon steel sheets are fixed to each other. The fixing holes of the multiple silicon steel sheets are aligned to form a limiting channel. This results in the need to pre-fix the multiple silicon steel sheets to form an iron core during the assembly of the iron core, and then clamp the iron core with channel steel and limit the iron core with limiting bolts. The entire assembly process is relatively cumbersome. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a transformer core assembly workbench. By adding a fixing rod, the channel steel and the silicon steel sheet are directly put onto the fixing rod in sequence for assembly.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] Specific embodiments, such as Figure 1-8 As shown, the utility model provides a transformer core assembly workbench, including a table top 1 and support legs 2, a fixed seat is provided on the table top 1, a fixed rod 3 is provided on the fixed seat in the vertical direction, a first fixing hole 5 and a first limiting hole 6 are provided at the bottom of the channel steel 4 along the length direction, the channel steel 4 is sleeved on the fixing rod 3 with the help of the first limiting hole 6 and the open side of the channel steel 4 abuts against the fixed seat, a second fixing hole 7 and a second limiting hole 8 are provided on the surface of the silicon steel sheet 18, a plurality of the silicon steel sheets 18 are sleeved on the fixing rod 3 with the help of the second limiting hole 8 to form an iron core, a plurality of the second fixing holes 7 of the silicon steel sheets 18 are aligned with the first fixing holes 5 of the channel steel 4 and form a limiting channel for the limiting bolt 9 to pass through, and the channel steel 4 is away from the table top 1 with the help of the fixed seat.

[0023] During the process of assembling the iron core, multiple silicon steel sheets 18 need to be pre-fixed to form the iron core, and then the iron core is clamped by the channel steel 4 and limited by the limiting bolts 9. The entire assembly process is relatively cumbersome.

[0024] Therefore, a fixing rod 3 is provided in the present invention. During assembly, the channel steel 4 and the silicon steel sheet 18 are directly put onto the fixing rod 3 in sequence. Multiple groups of silicon steel sheets 18 are stacked and arranged to form an iron core. Then another group of channel steels 4 is put onto the fixing rod 3. The two groups of channel steels 4 clamp the iron core together. Finally, the limiting bolts 9 are used to pass through the channel steel 4, the iron core, and the channel steel 4 in sequence for fixation, and the two groups of channel steels 4 are fixed using the tension bolts 19.

[0025] When the workbench of the present invention is used for assembly, there is no need to pre-fix the silicon steel sheet 18 to maintain the structure of the iron core. It only needs to be fixed with the limit bolts 9 and the tension bolts 19 at the end. The entire assembly process is simple and can be operated by one person, thereby improving assembly efficiency.

[0026] In addition, the seat cushion in the present invention is fixed to the bottom of the channel steel 4, so that the channel steel 4 is away from the table 1 and supported in mid-air. The space formed between the bottom of the channel steel 4 and the table 1 is convenient for the staff to install the limit bolts 9 and the tension bolts 19.

[0027] like Figure 7-8 As shown, the table top 1 is provided with adjustment holes 10 in a rectangular array, and the fixed seat is provided with two groups, and the fixed seat includes a fixed column 11, a movable column 12 and a connecting beam 13. The fixed column 11 is fixedly connected to the table top 1 by means of a fixing bolt 14 passing through the adjustment hole 10, and the movable column 12 has the freedom to rotate with the fixed column 11 as the center, and the movable column 12 is detachably fixedly connected to the table top 1 by means of an adjusting bolt 17 passing through the adjustment hole 10. The fixed columns 11 and the movable columns 12 of the two groups of fixed seats are arranged in a quadrilateral, and the connecting beams 13 of the two groups of fixed seats are moved closer to or away from each other by the swing of the movable column 12, and the fixed rods 3 on the two groups of fixed seats are swung by the connecting beam 13 to form a distance adjustment.

[0028] Since the models of transformers are different, the models of silicon steel sheets 18 are also different. Therefore, the spacing between the fixing seats in the present invention is adjustable. The fixing column 11 and the movable column 12 can be directly disassembled, and then the fixing seat is translated and repositioned through different adjustment holes 10. The spacing between the fixing rods 3 is adjusted according to the spacing between the two second fixing holes 7 of the silicon steel sheet 18; if the spacing between the fixing rods 3 is not an integer multiple of the distance between adjacent adjustment holes 10, the movable column 12 can be swung around the fixing column 11 as the center to form a Figure 7 The parallelogram-shaped twist shown can also be formed as Figure 8 The “eight”-shaped swing shown moves the connecting beams 13 of the two sets of fixing seats closer or farther away, thereby fine-tuning the spacing between the fixing rods 3 to match the spacing between the two second fixing holes 7 of the silicon steel sheet 18 .

[0029] The fixed end of the connecting beam 13 is fixedly connected to the top of the movable column 12, and the movable end of the connecting beam 13 is slidably matched with the top of the fixed column 11. When the distance between the fixed rods 3 is appropriate after the movable column 12 is swung, the screw hole of the movable column 12 may not be aligned with the adjustment hole 10. At this time, the connecting beam 13 can be slid and the movable column 12 can be moved so that the movable column 12 moves to the adjustment hole 10 at the corresponding position and is fixed.

[0030] The movable end of the connecting beam 13 is provided with an elongated groove 16 which passes through the connecting beam 13 in the vertical direction. The movable end of the connecting beam 13 is connected to the top of the fixed column 11 by means of a limiting rod 15 which passes through the elongated groove 16. The movable column 12 forms a sliding fit with the fixed column 11 by means of the elongated groove 16 and has the freedom to approach and move away from the fixed column 11. The elongated groove 16 can provide the connecting beam 13 with the freedom of rotation and sliding. At the same time, when the fixed column 11 and the movable column 12 are both fixed, since the fixed end of the connecting beam 13 is fixed to the movable column 12, the movable end of the connecting beam 13 is also fixed in position under the limitation of the elongated groove 16, and the elongated groove 16 plays a limiting role.
