Description

TECHNICAL FIELD

[0001] The utility model relates to motor manufacturing technical field, concretely is a motor silicon steel sheet hot pressing adhesion forming jig. BACKGROUND

[0002] Motor silicon steel sheet refers to the silicon steel sheet used for manufacturing motor, and it is an extremely low carbon steel plate containing silicon with a mass fraction usually below 2.5%. In the motor manufacturing process, multiple silicon steel sheets are adhered together through high temperature and high pressure to form the required core of the motor, which not only forms a firm connection between the silicon steel sheets to ensure that the silicon steel sheets can be tightly adhered together without defects or cracks, but also reduces air gap and eddy current loss, thereby improving electromagnetic performance. In order to help positioning the position of the motor silicon steel sheet and ensure its accuracy and quality in the production process, a motor silicon steel sheet hot pressing adhesion forming jig is proposed.

[0003] According to the search, the Chinese patent document, publication number: CN211573959U, discloses a motor silicon steel sheet hot pressing adhesion forming jig structure, which comprises a sleeve seat, a plurality of sleeves, an upper clamping plate, a plurality of pressing columns, a plurality of pressing bolts and a plurality of pressing nuts. The sleeve seat is provided with a plurality of sleeve holes. The sleeves are sleeved on the outer circumferential side of the sleeve seat. The upper clamping plate is provided with a plurality of pressing column holes. The pressing columns are sleeved on the pressing column holes of the upper clamping plate. The pressing bolts are respectively sleeved on the outer circumferential side of the sleeves. The pressing nuts are respectively screwed on the pressing bolts. The pressing columns are pressed against the top ends of the silicon steel sheets on the sleeve seat. The upper clamping plate is pressed by the pressing nuts. The displacement of the upper clamping plate and the pressing columns is adjusted by the pressing bolts. The force of the pressing columns pressing against the silicon steel sheets is adjusted. However, the device needs to be manually aligned when the multiple silicon steel sheets are sleeved on the sleeve seat, which increases unnecessary workload and work difficulty. In addition, the device needs to use multiple bolts and nuts to press and fix the silicon steel sheets, which is cumbersome to disassemble and reduces the overall work efficiency of the device. SUMMARY

[0004] (I) Technical problem solved

[0005] In view of the deficiencies of the prior art, the utility model provides a motor silicon steel sheet hot pressing adhesion forming jig, which has the advantages of convenient operation, precise installation, easy disassembly and improved work efficiency, and solves the above technical problems.

[0006] (II) Technical scheme

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hot-pressing bonding forming jig for motor silicon steel sheets, comprising a worktable, a hot press box and a limiting post fixedly installed on the top surface of the worktable, a central post and a limiting plate installed inside the hot press box, a silicon steel sheet body installed on the outer side of the central post, a top plate fixedly installed at the top of the limiting post, a hydraulic cylinder fixedly installed on the top surface of the top plate, a cover plate fixedly connected to the output shaft of the hydraulic cylinder, and a clamping block fixedly installed on the bottom surface of the cover plate.

[0008] Preferably, the top of the central column is set as a hemisphere, and the inner diameter of the silicon steel sheet body is equal to the diameter of the central column.

[0009] With the above technical solution, when the silicon steel sheet body is installed inside the hot press box, the hemisphere at the top of the central column can play a good guiding role in the installation. At the same time, the central column can initially limit and fix the position of multiple silicon steel sheet bodies, thereby improving the overall stability and practicality of the device.

[0010] Preferably, the number of limiting plates is four, and the inner bottom surface of the hot press box is provided with four first grooves, and the four limiting plates are respectively installed inside the four first grooves.

[0011] Through the above technical solution, the four limiting plates can not only effectively restrict the position of the silicon steel sheet body, but also facilitate disassembly and assembly. When facing silicon steel sheets of different sizes and models, they can be adjusted to the corresponding positions, which improves the overall convenience and practicality of the device.

[0012] Preferably, there are multiple silicon steel sheet bodies, and the top surface of each of the multiple silicon steel sheet bodies is provided with multiple slots, and the limiting plate is installed inside the slots.

[0013] The above technical solution allows the slots of multiple silicon steel sheets to be correspondingly engaged with the outer surface of the limiting plate, thereby effectively restricting their position to prevent positional deviation. This not only facilitates installation for workers but also ensures the precision and quality of the product.

[0014] Preferably, the number of limiting posts is four, and the cover plate is slidably installed on the outer surface of the four limiting posts.

[0015] By using the above technical solution, the hydraulic cylinder is activated, and the output shaft of the hydraulic cylinder can drive the cover plate to move in the vertical direction. At the same time, the four limit posts can limit the horizontal position of the cover plate, thereby improving the overall stability of the device.

[0016] Preferably, the bottom surface of the clamping block has a plurality of second grooves.

[0017] With the above technical solution, when the hydraulic cylinder moves the cover plate to the position of the hot press box, the cover plate can effectively seal the hot press box to facilitate the subsequent hot pressing treatment of the silicon steel sheet body inside. At the same time, the multiple second grooves can reserve the positions of the central column and the limiting plate, improving the overall practicality of the device.

[0018] Compared with the prior art, this utility model provides a hot-pressing bonding mold for motor silicon steel sheets, which has the following beneficial effects:

[0019] 1. This utility model installs the silicon steel sheet body inside the hot press box. The hemispherical part at the top of the central column can play a good guiding role in the installation. At the same time, the central column can initially limit and fix the position of multiple silicon steel sheet bodies. In addition, the grooves of multiple silicon steel sheet bodies are correspondingly engaged with the outer surface of the limiting plate, which can effectively limit their position and prevent positional deviation. Therefore, it not only facilitates the installation of workers, but also ensures the accuracy and quality of the product. Furthermore, when dealing with silicon steel sheet bodies of different sizes and models, the limiting plate can also be adjusted to the corresponding position inside the first groove, improving the overall convenience and practicality of the device.

[0020] 2. This utility model uses a hydraulic cylinder to activate the hydraulic cylinder, which drives the cover plate to move vertically. At the same time, four limiting posts can limit the horizontal position of the cover plate. The cover plate can effectively seal the hot press box to facilitate the subsequent hot pressing of the silicon steel sheet body inside. Meanwhile, multiple second grooves can reserve the positions of the central post and the limiting plate, improving the overall practicality of the device. Attached Figure Description
