Description

Technical Field

[0001] The utility model relates to the technical field of punching sheet grinding devices, in particular to a motor punching sheet grinding device. Background Art

[0002] A common motor is mainly composed of a stator, a rotor and a base. The stator is fixed on the base, and the rotor is placed inside the stator. The rotating shaft passes through the rotor. When the stator is energized, the rotor rotates due to the law of electromagnetic induction, thereby driving the rotating shaft to rotate and converting electrical energy into mechanical energy. The stator is composed of multiple stator silicon steel sheets stacked together. During the production process of the punching sheets, the burrs generated on the surface during the production of the punching sheets are polished by a punching sheet polishing device. The punching sheet polishing device is composed of a rack, a conveyor belt, a fixed rack, a first motor, a workbench, a rotating shaft and a polishing roller. When the burrs of the motor punching sheets are polished, the punching sheets are moved by the conveyor belt on the rack, and the first motor is started to drive the workbench to rotate. The motor inside the workbench drives the rotating shaft to rotate, thereby causing the polishing roller to rotate. When the punching sheets pass through the polishing roller, the polishing roller polishes the punching sheets to eliminate the burrs on the surface.

[0003] The inventor found in his daily work that during the use of the punching sheet grinding device, the punching sheet needs to be ground with a grinding roller to grind the burrs when being ground. The accuracy of the grinding burrs is determined by the mesh size of the grinding roller used. When a punching sheet with a lower grinding accuracy needs to be ground, more grinding rollers need to be replaced for grinding. The prior art uses multiple sets of bolts to fix the grinding rollers. When the grinding rollers are replaced, it is not easy to tighten the bolts because the rollers are rotating during the process of removing and tightening the bolts, which affects the replacement efficiency and further affects the progress of grinding the punching sheet. Utility Model Content

When a punching sheet with a lower grinding accuracy needs to be ground, it is necessary to replace more grinding rollers for grinding. The prior art adopts a multi-group bolt fixing method to fix the grinding roller. When the grinding roller is replaced, it is not easy to tighten the bolts because the roller is rotating during the process of removing and tightening the bolts, which affects the replacement efficiency and further affects the progress of grinding the punching sheet. A motor punching grinding device is proposed.

[0007] Preferably, a spring is fixedly connected to one side of the fixing rod, and the other end of the spring is fixed to the rotating shaft.

[0008] The effect achieved by the above components is that the position of the clamping block changes, thereby separating from the bottom of the fixing rod, and at this time the spring is reset to drive the fixing rod to move.

When replacing the grinding roller, the rotating rod in the operating groove is rotated to change the position of the block, thereby separating it from the bottom of the fixing rod, so that the fixing rod is separated from the fixing groove, and the grinding roller is dragged to separate it from the rotating shaft. The replaced grinding roller is dragged onto the rotating shaft, and the rotating rod is rotated to squeeze the fixing rod into the fixing groove, so that the grinding roller is fixed, and the replacement of the grinding roller is completed. The problem that the burrs of the punching sheet need to be polished by the grinding roller when being polished is solved. The accuracy of the polishing burrs is determined by the mesh number of the grinding roller used. When a punching sheet with lower polishing accuracy needs to be polished, more grinding rollers need to be replaced for polishing. The prior art adopts a multi-group bolt fixing method to fix the grinding roller. When replacing the grinding roller, it is not easy to tighten the bolts because the roller is rotating during the process of removing and tightening the bolts, which affects the replacement efficiency and further affects the progress of polishing the punching sheet.

Under the auxiliary limit of the sliding rod 304, the limit clamping block 306 moves under the rotation of the screw rod 305, and then turn the screw rod 305 on the other side to make the limit clamping block 306 clamped on the rack 1, thereby fixing the perforated U-shaped frame 301.
