Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer lamination assembly tool. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It is widely used in industries such as industry, agriculture, transportation, and urban communities. For the silicon steel sheet stacking inside the transformer, the stacking tooling used in the existing stacking method is not only very expensive but also complicated to operate, has high costs, and has low production efficiency. The resulting stacking structure does not meet the requirements, and there are large seams in the structure. Patent documents have now been issued to improve this.

[0003] For example, Chinese patent CN205789483U, a transformer lamination assembly tool, including a group of mountain-shaped laminations and a group of upper iron yoke laminations, the mountain-shaped lamination has a lower iron yoke part and three core column parts, the upper iron yoke lamination is arranged on the three core column parts of the mountain-shaped lamination, the upper iron yoke lamination and the mountain-shaped lamination form a closed structure, the lower iron wheel part of the mountain-shaped lamination is penetrated with a first positioning steel rod, the front and rear sides of the lower iron yoke part are respectively provided with a first positioning piece, the end of the first positioning steel rod passes through the first positioning piece, the upper iron yoke lamination is penetrated with a second positioning steel rod, the front and rear sides of the upper iron yoke lamination are respectively provided with a second positioning piece, the end of the second positioning steel rod passes through the second positioning piece, the front and rear sides of the mountain-shaped lamination are respectively provided with a clamping channel steel across the three core column parts, and the two clamping channel steels are connected by screws. The utility model is relatively convenient to operate, saves time and effort, saves costs, has high production efficiency, and the formed lamination structure meets the requirements without seams.

[0004] Although the equipment in the above document positions the laminations by installing steel chisels, it still has obvious defects in actual use, such as:

[0005] The volume of transformers is generally large, resulting in a relatively large volume of internal laminations. Although the setting of the steel chisel can position the laminations, the workers need to connect the three holes with the steel chisel one by one during installation to complete the installation, which reduces the installation speed. In addition, if the equipment is to be used, it is also necessary to punch holes at the corresponding positions on the top of the laminations to change its overall shape, which undoubtedly increases the cost.

[0006] Therefore, a transformer lamination assembly tool that can not change the shape of the lamination and is easy to use is now designed to solve such defects. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a transformer lamination assembly tool, which solves the problem that the prior transformer lamination tool needs to change the shape of the laminations and is cumbersome to install.

[0008] To achieve the above purpose, the utility model is implemented through the following technical scheme: a transformer lamination assembly tool, including a lamination body installed on the top of a base plate, the front and rear parts and both sides of the base plate are provided with rectangular slide grooves, a guide slide frame slides on the inner side of the rectangular slide groove, a correction splint is fixedly connected to the top of the guide slide frame, and two correction splints are provided, and a concave top plate is fixedly connected between the top ends of the two correction splints.

[0009] Preferably, one side of the top of the concave top plate is rotatably connected to a transverse rod through a bearing member, and one end of the top of the transverse rod away from the concave top plate is fixedly connected to a ramp block, an upper pressure plate is provided on the upper part of the laminate body, and the front, rear and both sides of the top of the upper pressure plate are provided with limiting grooves for use with the ramp block.

[0010] Preferably, a positioning socket is provided on one side of the inclined block, and both sides of the top of the upper pressure plate and the front and rear are fixedly connected with L-shaped blocking plates, and a latch rod used in conjunction with the positioning socket is slidably installed on the inner side of the L-shaped blocking plate, a spring is sleeved on the surface of the latch rod, and one end of the latch rod is fixedly connected with a baffle plate used in conjunction with the L-shaped blocking plate.

[0011] Preferably, the top of the concave top plate is provided with a side opening extending through to the bottom, and both sides and the front and rear of the upper pressure top plate are fixedly connected with L-shaped plug plates used in conjunction with the side openings.

[0012] Preferably, the bottom of the L-shaped plug plate is fixedly connected to a compression seat used in conjunction with the laminate body via a fixing plate. Beneficial Effects

[0014] (1) The transformer lamination assembly tooling is equipped with correction clamps on both sides, front and rear of the base plate by using guide slides, and is used in conjunction with inclined blocks and upper pressure plates. The arrangement of these structures can quickly install the laminations on the top of the base plate without changing the shape of the laminations, and then use the limit grooves to squeeze the transverse rods so that the correction clamps and the compression seats can press the sides and top of the laminations to correct and fix their positions, thereby ensuring the overall neatness and reducing gaps, and satisfying current use.

[0015] (2) The transformer lamination assembly tooling has a positioning socket on one side of the inclined plane block and is used in conjunction with a latch rod. The arrangement of these structures can connect the upper pressure plate with the inclined plane block through the limit groove, and then the inclined plane block is plugged in using the latch rod, so that the linkage between the structures is used to lock the entire device, thereby ensuring stability during operation.
