The lathe body 1 is internally provided with a machining assembly for machining a motor housing.

The working principle of the motor shell processing lathe provided by the utility model is as follows:

Placing the motor shell to be processed on the top of one of the rotating blocks 3, placing the bottom of the motor shell above the placing groove of the rotating block 3, starting a driving motor 17 in the lathe body 1, driving the rotating table 2 to rotate 90 degrees by the output end of the driving motor, enabling the next empty rotating block 3 to rotate to a feeding station, repeating the operation, and placing the motor shells to be processed on all the rotating blocks 3 in sequence to finish initial feeding;

Because the two ends of the U-shaped rod are in spherical design and are contacted with the tops of the inclined grooves 16 at the two sides of the mounting frame 10, the U-shaped rod can press the inner wall of the inclined groove 16 when moving, so that the mounting frame 10 is forced to slide upwards along the axial direction of the guide rod 11;

When the mounting frame 10 moves upwards, the motor I12 in the mounting frame moves upwards synchronously to drive the friction roller 5 at the top to be close to the bottom of the rotating block 3 of the current processing station, the friction roller 5 is gradually embedded into the friction groove 9 at the bottom of the rotating block 3, and the spring II 13 in the friction roller 5 is compressed along with the continuous pushing of the electric push rod 14, so that the friction roller 5 is tightly attached to the inner wall of the friction groove 9, and the follow-up friction transmission is ensured to be reliable;

because the middle part of the top block 18 is designed into a round table shape, the outer wall of the top block can squeeze the magnetic ball block at the end part of the sliding cylinder 7 when the top block moves upwards, so that the sliding cylinder 7 is forced to move towards the outer side of the placing groove;

When the sliding cylinder 7 moves, the clamping plate 4 is driven to synchronously and outwards diffuse through the connecting cylinder 6 to gradually contact the inner wall of the motor shell, and as the jacking block 18 continues to move upwards, the spring I8 on the inner wall of the sliding cylinder 7 is compressed to generate reverse elastic force, and the clamping plate 4 is pushed by the connecting cylinder 6 to tightly attach to the inner wall of the motor shell, so that the workpiece fixing is completed;

Because the friction roller 5 is closely attached to the friction groove 9, the friction force drives the rotating block 3 of the current processing station to synchronously rotate, so that the clamped motor shell rotates;

Starting a machining assembly of the lathe body 1, and performing machining operations such as cutting and the like on the rotating motor shell until the preset precision is reached;

After the processing of the prior motor shell is finished, the motor I12 is closed, the friction roller 5 stops rotating, and the motor shell stops rotating along with the motor shell, then, the electric push rod 14 contracts to drive the U-shaped rod to reset, the mounting frame 10 slides downwards along the guide rod 11 under the action of gravity and the reset force of the spring II 13, the friction roller 5 gradually breaks away from the friction groove 9, after the friction roller 5 breaks away from, the top block 18 loses upward thrust, the spring I8 on the inner wall of the sliding cylinder 7 releases elasticity to push the sliding cylinder 7 to move towards the middle part of the placing groove, and meanwhile, the top block 18 is extruded to reset downwards;

When the sliding cylinder 7 moves, the magnetic ball blocks at the end parts of the sliding cylinder are mutually adsorbed to drive the connecting cylinder 6 and the clamping plate 4 to synchronously shrink inwards to separate from the inner wall of the motor shell, so that the fixation is released;

Then, starting a driving motor 17 to drive a rotating table 2 to rotate 90 degrees, so that a rotating block 3 where a next motor shell to be processed is positioned moves to a processing station, and simultaneously, rotating the processed motor shell by 90 degrees to a feeding station;

And when the machined motor shell rotates to the feeding station, an operator takes down the machined motor shell and places the new motor shell to be machined, so that continuous batch production is realized.
