The utility model has the advantages that:
the three-jaw chuck is connected to the outer portion of the main shaft, so that three-jaw fixing is more stable in work. Two of the fixed clamping jaws 6 are fixed in length, one movable clamping jaw 7 is adjustable in length, the adjustable wrench 3 is screwed through clockwise rotation, the movable clamping jaw 7 cannot rotate because the fixed bolt 8 extends into the guide groove, the adjustable clamping jaw 3 is moved downwards to be in contact with the fixed seat 10 when the adjustable wrench 3 is screwed, the adjustable wrench 3 is continuously screwed clockwise rotation at the moment, the movable clamping jaw 7 moves along the radial direction of the chuck to the outer radial side, the end parts of the three clamping jaws can be integrally attached to the inside of the stator core, the clamping jaw is not prone to shaking after being clamped, and the clamping jaw can adapt to stator cores of different sizes; at this time, the fixing bolt 8 may be tightened such that the fixing bolt 8 is pressed against the bottom surface of the guide groove on the movable jaw 7, preventing the movable jaw 7 from moving. Therefore, the position of the movable clamping claw can be further limited, so that the movable clamping claw is stably contacted with the inside of the iron core, and the locking state is kept unchanged.
When the chuck is disassembled, the fixing bolt 8 needs to be loosened firstly, then the adjustable wrench 3 needs to be screwed in a counterclockwise rotating mode, the movable clamping jaw 7 moves to the inner radial side along the radial direction of the chuck, and the chuck is convenient and quick to install and disassemble.
The canvas belt at the end part of the clamping jaw enables the clamping chuck to be in indirect contact with the inside of the iron core, and the iron core is prevented from being damaged. The movable clamping jaw is connected with the screwing adjustable wrench through the T-shaped threads, so that the length of the movable clamping jaw can be conveniently adjusted in work, the stability of the movable clamping jaw in the use process is guaranteed, a good locking state is kept, and the stability of the tool is guaranteed.
The chuck is in threaded connection with the spindle, the axial length of the spindle is adjustable, the position of the chuck outside the spindle is adjustable, and the chuck can move freely according to the length of an iron core. The rolling disc is connected with the main shaft in a dismounting mode, can be freely replaced according to iron cores of different sizes, and is high in interchangeability.
