A machine body of the numerical control notching machine is provided with a motor seat; an alternating current servo motor is arranged on the motor seat; an output shaft of the alternating current servo motor and an eccentric crank axle are provided with a synchronous pulley respectively; the two synchronous pulleys are connected through a synchronous belt; and the eccentric crank axle is provided with a sliding block part, and the central line of support axle holes at two ends of the crank axle is parallel to a plane of a work table of the machine body. The structure is high in transmission accuracy, can accurately control the position, speed and acceleration of a punch (the sliding block), reduce the notching noise, vibration of a main unit and loss of a die, is convenient to operate and improves production efficiency; a lubrication system is not needed; and the stopping position of the punch (the sliding block) can be freely selected.
Description
Technical field
The utility model relates to motor iron core process equipment notching press field, and is a kind of for the Timing Belt driving crank structure of the servomotor on the numerical control notching press specifically.
Background technology
Numerical control notching press is the single groove punching special equipment for stamping-out rotor or stator lamination slotted eye.The punch die of punching rotor or stator lamination is installed between drift (slide block) and the workbench, by pumping of drift (slide block), drives patrix and pumps.Need the lamination (punching) of jet-bedding to be installed on the indexing means with intermittent movement, by indexing means lamination (punching) is rotated by default requirement.When drift (slide block) when moving downward, lamination (punching) does not turn the wait jet-bedding, when drift (slide block) when moving upward, and lamination (punching) rotary index, through the dividing movement in a week, can finish the jet-bedding process of a lamination (punching).At present, numerical control notching press is to adopt servomotor to drive the eccentric crankshaft rotation by a pair of gear engagement, and crankshaft two end back shaft centerline hole is vertical with the slide block guide rail face.So that drift (slide block) pumps, finish the stamping-out process.This type of belt drive complex structure, fuselage shaking is large, and quick-wear part is many, and the complicated fuselage shaking of maintaining is large.
The utility model content
The problem that exists for solving prior art, the purpose of this utility model provides a kind of for the structure of the servomotor on the numerical control notching press with the Timing Belt driving crank, adopt servomotor to drive eccentric crankshaft by Timing Belt and do whole circle (360 °) rotation or swing, the drift slide block is pumped, thereby finish the jet-bedding process.
The technical solution adopted in the utility model is as follows:
A kind of for the structure of the servomotor on the numerical control notching press with the Timing Belt driving crank, it is characterized in that: include motor cabinet, motor cabinet is installed on the fuselage of numerical control notching press, AC servo motor is installed in the motor cabinet, be separately installed with a synchronous pulley on the output shaft of AC servo motor and the eccentric crankshaft, connect by Timing Belt between two synchronous pulleys, the rotation of AC servo machinery driving eccentric crankshaft, the drive Slipper is done and is pumped.
Described eccentric crankshaft by bearing laterally be installed in fuselage about put greatly and eccentric crankshaft two end supports axis hole center line parallel with the fuselage table plane.
Be fixed by screws on the described motor cabinet on the fuselage of numerical control notching press.
The center line in described eccentric crankshaft two end supports hole is parallel with the mounting plane of the guide rail of Slipper.
Described two synchronous pulleys and Timing Belt can be replaced by the gear of pair of meshing.
Described two synchronous pulleys and Timing Belt also can be replaced by pulley concial disk and V belt.
Compared with the prior art, advantage of the present utility model is as follows;
The utility model is simple in structure, and transmission accuracy is high, can accurately control position, speed and the acceleration of drift (slide block).Can reduce the jet-bedding noise, reduce the vibrations of main frame, reduce the mould loss, and can freely select the stop position of drift (slide block), easy to operate, improved production efficiency.
