The utility model has the advantages that: the servo motor assembly is directly in meshed transmission with the large gear through the teeth arranged at one end of the motor output shaft, and the safety brake is directly arranged on the motor end cover and is sleeved outside the output shaft in a penetrating manner to be connected with the output shaft, so that the driving structure of the press machine is simplified, the reliability is improved, and the installation is convenient.
Description
Technical Field
The utility model relates to a servo motor assembly and press of press.
Background
With the development and maturity of the ac servo control technology and its advantages of environmental protection, energy saving, flexible control, etc., the traditional mechanical or hydraulic press has been gradually replaced by the servo press. The servo press is generally a press driven and controlled by a servo motor, and mainly provides a pressing force by means of instantaneous torque of the servo motor, a pinion is generally driven by the servo motor to rotate, and then the pinion is meshed with a gearwheel arranged on a crankshaft to drive the crankshaft to rotate, so that a connecting rod arranged on the crankshaft drives a sliding block to move up and down. When the press is suddenly de-energized, the brake can prevent the brake gear connected with the press from rotating, and the brake gear is also meshed with the large gear, so that the crankshaft is prevented from rotating. The pinion of the transmission mechanism and the brake gear of the brake mechanism are separated, so that the structure is complex, the installation is troublesome, and the reliability is low.

Fig. 2 is a schematic structural diagram of a press machine according to an embodiment of the present invention after a safety brake is removed from a servo motor assembly.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1 and 2, a servo motor assembly of a press machine includes: the motor stator and rotor, the front end cover 2, the rear end cover 3, the output shaft 4 and the safety brake 5.
The stator and the rotor of the motor comprise a stator 1 and a rotor (not shown in the figure), and the rotor is arranged in the stator, sleeved outside the output shaft 4 in a penetrating manner and fixedly connected with the output shaft.
The front end cover 2 and the rear end cover 3 are respectively arranged at two sides of the stator 1, and the output shaft 4 sequentially penetrates through the rear end cover 3, the stator and the rotor and the front end cover 2.
One end of the output shaft 4 is provided with teeth 401 which can be meshed with the gearwheel for transmission, and the other end of the output shaft is provided with splines 402 which are in splined connection with the safety brake 5.
The teeth 401 of the output shaft 4 of the servo motor assembly of the press machine are meshed with the large gear together, so that a new press machine is formed.
When the press machine is used, the servo motor is electrified, the rotor drives the output shaft 4 to rotate, the gear wheel is driven to rotate through the teeth 401, the crankshaft is driven to rotate, and the sliding block moves up and down. When the press loses power suddenly, the brake block of the safety brake 5 prevents the output shaft 4 from rotating, so that the slide block of the press cannot float, and the safety of personnel and equipment is ensured.
