Description

Technical Field

[0001] The invention relates to the technical field of roller assembly, in particular to a roller electromagnetic induction heating and shaft threading device. Background Art

[0002] Roller assembly is an important task in mechanical manufacturing and maintenance, involving the assembly of multiple parts into a complete roller structure; rollers are widely used in conveyors, printing machines, textile machinery, food processing equipment and other fields. Their quality and performance directly affect the operating efficiency and reliability of the entire equipment. The roller body and the shaft are interference fit. The cylinder hole needs to be heated before assembly, and the shaft is inserted after the hole is enlarged by thermal expansion and contraction. Due to the large volume of the cylinder, the shaft is a through shaft; it needs to be placed horizontally during heating. The easiest way to insert the shaft is to place the cylinder vertically, lift the shaft and insert it from top to bottom. After inserting the shaft, the cylinder needs to be placed horizontally for stable placement. Due to the weight and volume of the cylinder, and the need to be turned over many times during the assembly process, it is not convenient to turn it over due to the influence of the cylinder volume.

[0003] For example, a Chinese patent with application number 202021823892.2 discloses a shaft cylinder that is easy to assemble, including a bearing seat, a bearing fixedly installed inside the bearing seat, and a sleeve fixedly installed inside the bearing. The shaft cylinder that is easy to assemble has the effect of being easy to install and disassemble through the setting of connecting rods and springs. Through the matching setting of positioning holes and positioning pins, during use, the connecting rods and bolts form a seesaw structure. When the pressing block is pressed down, the positioning pin can be driven upward by the connecting rod to achieve the removal of the positioning pin 13, and the rotating shaft is slid out under the action of the limiting platform of the rotating shaft and the sleeve. On the contrary, when the pressing block is released, the pin at one end of the connecting rod is pushed downward under the action of the spring, and the positioning pin is inserted into the positioning hole to achieve positioning restriction, thereby playing the role of convenient installation and flexible axial adjustment, and achieving the purpose of simple structure and high practicality.

[0004] Although the invention makes the shaft tube easy to install and disassemble through the arrangement of connecting rods and springs, and the positioning holes and positioning pins are arranged in coordination, the tube and the shaft need to comply with the interference fit assembly process during the connection process, making it difficult to assemble the tube by direct plug-in, which makes it inconvenient to heat and expand the tube.
