Description

Technical Field

[0001] The utility model relates to the technical field of equipment processing, in particular to a dividing device for a high-speed notching machine. Background Art

[0002] The stator and rotor cores of motors are important components of motors. When developing and producing motors of multiple varieties, small batches, and larger sheet diameters, a notching machine is usually used to punch out single sheets slot by slot. Since the sheets are very thin, a motor often requires hundreds to thousands of sheets, and the labor intensity of workers is extremely high. Automated notching technology can liberate workers from heavy physical labor. The motor has a stator and a rotor. The current general process is to separate the rotor discs while punching the stator slots. The sheet blank is positioned with a center hole and is mounted on a dividing spindle pallet that can rotate intermittently. The entire sheet is supported by a sheet support platform driven by a cylinder to rise and fall. After the punching is completed, the sheet support platform rises to separate the rotor center hole from the dividing spindle pallet. Then the robot suction cup grabs the sheet and places it on the material stack. Since the sheet support platform vibrates greatly during the lifting process, the sheet will be displaced, resulting in uneven sheet formation, which affects the subsequent stacking of the entire unit.

[0020] Example

[0021] Reference Figures 1-2 , is a specific embodiment of the utility model, which provides a dividing device for a high-speed notching machine, including a dividing outer shaft 8 and a dividing inner shaft 7 arranged in the dividing outer shaft 8, the dividing outer shaft 8 and the dividing inner shaft 7 are axially slidingly connected, the dividing inner shaft 7 is fixedly connected to the tray 1 through the core shaft 2, and the dividing inner shaft 7 is controlled to rise and fall by the pull rod 13, so that the tray 1 is in contact with or separated from the punching sheet 3 on the sheet supporting platform 4; a disc spring 11 and a gasket 12 are provided in the dividing inner shaft 7, and the disc spring 11 is used to support the dividing inner shaft 7; the bottom of the pull rod 13 is rotatably connected to the connecting rod 16 through a connecting sleeve 15, and the connecting rod 16 is connected to the piston rod 18 of the cylinder 19 through a transition plate 17; a guide sleeve 14 connected to the inner wall of the dividing outer shaft 8 is provided on the pull rod 13.

[0022] The outer indexing shaft 8 is connected to the indexing box through two pairs of upper and lower bearings, and then the servo motor drives the reduction mechanism to rotate to complete the indexing action. The sheet supporting platform 4 is fixedly connected to the indexing box and remains stationary throughout the entire punching process to avoid positional offset of the punching sheet 3 and affect the stacking neatness.

[0023] A retaining frame 9 is provided between the indexing outer shaft 8 and the indexing inner shaft 7, and balls 10 arranged in multiple rows are provided on the retaining frame 9, and the balls 10 roll along the surfaces of the indexing inner shaft 7 and the indexing outer shaft 8; a guide key 6 is provided in the indexing outer shaft 8 for limiting the relative rotation between the indexing outer shaft 8 and the indexing inner shaft 7, and the guide key 6 is slidingly connected to the indexing inner shaft 7; a pressure cover 5 is fixedly connected to the indexing outer shaft 8; a wedge tooth 20 and a wedge groove 21 are respectively provided on the indexing inner shaft 7 and the pressure cover 5, and the wedge tooth 20 and the wedge groove 21 are used to fit the indexing inner shaft 7 and the pressure cover 5 tightly.

[0024] The guide key 6 is fixedly connected to the indexing outer shaft 8 and is slidably connected to the indexing inner shaft 7, which limits the relative rotation of the indexing inner shaft 7 and the indexing outer shaft 8, so that the indexing inner shaft 7 can only move along the axial direction; the retaining frame 9 is cylindrical and located between the indexing inner shaft 7 and the indexing outer shaft 8. A number of circular holes are evenly opened on the retaining frame 9. The ball 10 is embedded in the hole of the retaining frame 9 and can rotate. The surface of the ball contacts the outer surface of the indexing inner shaft 7 and the inner surface of the indexing outer shaft 8, playing a guiding role.

[0025] Working principle: Before punching begins, the cylinder 19 is unloaded, and the indexing inner shaft 7 is pushed under the action of the disc spring 11, so that the wedge teeth 20 on the indexing inner shaft 7 are tightly fitted with the wedge groove 21 on the pressure cover 5, and then punching is carried out. After the punching is completed, the cylinder 19 is started to drive the piston rod 18 to move downward. The piston rod 18 drives the indexing inner shaft 7 and the tray 1 to move downward synchronously through the intermediate connector and the pull rod 13, so that the punching sheet 3 is separated from the tray 1. After the robot suction cup takes the sheet away, the cylinder 19 is unloaded, and the disc spring 11 pushes the indexing inner shaft 7 and the tray 1 to move up to the position shown in FIG. Figure 1 The initial state is shown, and the cycle continues.
