Description

Technical Field

[0001] The utility model relates to the technical field of iron core assembly, in particular to an iron core extrusion assembly tool. Background Art

[0002] Most motor stators are composed of multiple pieces of wound iron cores assembled into a ring shape after assembly. The ring-shaped motor stator is then converted and pressed into the motor housing through special automated or semi-automated equipment and tooling, so that the motor stator is installed in the motor as a whole; among them, patent No. 2023216930414 discloses a clamping tool for welding and assembling motor stator iron cores, which is a tool for assembling multiple pieces of iron cores into a ring shape. However, in the technical solution of this patent, the iron cores need to be loaded into the positioning grooves one by one. When the iron cores are assembled into a ring shape, the connection between two adjacent iron cores is relatively tight, which makes it difficult to load the iron cores into the positioning grooves. Therefore, the efficiency of this technical solution in assembling the iron cores into a ring shape is relatively low as a whole. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model provides an iron core extrusion assembly tool, which has a simple structure and can improve the iron core assembly efficiency.

[0004] The technical problem to be solved by the utility model is achieved through the following technical means: a core extrusion assembly tool, including a chuck module, an embedded ring and an outer holding ring, the chuck module includes a circular body and a plurality of fan-shaped shovel blocks moving radially along the circular body, a plurality of the fan-shaped shovel blocks form a shovel block assembly, the embedded ring is placed at the middle upper end of the shovel block assembly, the height of the embedded ring is higher than the height of the fan-shaped shovel block, a placement space for placing the core is formed between the outer side of the embedded ring and the inner side of the fan-shaped shovel block, when a plurality of cores are arranged in the placement space in a ring shape, the outer holding ring is sleeved on the upper outer side of the core.

[0005] In the above scheme, the multiple fan-shaped shovel blocks of the chuck module are movable, and the fan-shaped shovel blocks of the shovel block assembly are far away from each other, so that the placement space is relatively loose and the space is large, so that all the iron cores can be conveniently placed in the placement space, and then the multiple fan-shaped shovel blocks are moved closer to each other toward the center of the circular body. Due to the existence of the embedded ring, the multiple iron cores will naturally be tightly connected together in a ring shape under the internal and external actions of the embedded ring and the fan-shaped shovel blocks; the multiple iron cores that have become rings are then tightened by the outer ring to prevent the iron cores from collapsing; in addition, as long as the fan-shaped shovel blocks of the shovel block assembly are driven to a position away from each other, the placement space becomes a larger space again, so that the outer ring and the iron core can be realized as a whole and can be removed from the chuck module, which is convenient for the subsequent conversion and installation of the iron core into the motor housing. The utility model has a simple structure, and uses the thrust of the fan-shaped shovel blocks to naturally piece together multiple iron cores into a ring shape, which greatly improves the efficiency compared with the existing technology.

[0006] In one embodiment, the shovel block assembly includes four fan-shaped shovel blocks. When the four fan-shaped shovel blocks are tightly spliced ​​together as a whole, the shovel block assembly is in the shape of a disk with a circular hole in the middle, and the outer diameter of the embedded ring is larger than the inner diameter of the circular hole.

[0007] In the above scheme, the embedded ring is placed between the fan-shaped shovel blocks and will not fall into the circular hole.

[0008] In one embodiment, the chuck module includes a push block for driving the fan-shaped shovel blocks to move in a one-to-one correspondence.

[0009] In the above scheme, the chuck is a common clamping device. Conventional chucks use a matching manual handle to drive clamping and loosening. In the utility model, the push block of the chuck module also uses a conventional manual handle to achieve the movable displacement of the fan-shaped shovel block, so that multiple fan-shaped shovel blocks are in a clamped or loosened state.

[0010] In one embodiment, when a plurality of iron cores are arranged in the placement space in a ring shape, the outer diameter of the embedded ring is smaller than the inner diameter of the ring formed by the iron cores.

[0011] In the above scheme, the embedded ring is only a tool to assist multiple iron cores to be connected in a ring shape. When the iron cores are naturally squeezed to be connected in a ring shape, the embedded ring can be removed from the middle of the ring-shaped iron cores.

[0012] In one embodiment, a tapered docking portion is provided on the upper portion of the outer embrace ring, and the tapered docking portion is an annular protrusion provided on the inner upper end of the outer embrace ring, and the tapered docking portion is adapted to the outer casing of the motor on which the iron core is to be installed.

[0013] In the above scheme, the motor casing is provided with a bayonet at the position where the iron core is installed, and the shrink-fitting joint portion is just matched with the bayonet, and the outer holding ring can be inserted upside down in the motor casing, so that the annular iron core fastened by the outer holding ring can be conveniently aligned with the position of the casing where the iron core is installed.

[0014] In one embodiment, the core extrusion assembly tool includes a pressure ring, and the outer diameter of the pressure ring is smaller than the inner diameter of the outer holding ring.

[0015] In the above scheme, the pressing ring is used to cooperate with the pressing device to press the iron core in the outer holding ring into the core installation part of the motor housing in the form of an overall lowering. BRIEF DESCRIPTION OF THE DRAWINGS
