Abstract
The utility model discloses a motor direct-drive sewing machine comprising a nose, a nose end cover and a hand wheel. The nose is provided with a sewing mechanism which is connected with the motor through a spindle. The end, opposite to the nose, of the nose end cover is provided with a motor mounting hole. A motor stator is disposed in the motor mounting hole and fixedly connected. The nose end cover is fixedly connected with the nose. The nose end cover is further provided with a spindle through hole not larger than the motor mounting hole. The spindle passes the through hole and extends into the motor mounting hole to be connected with the motor rotor. The end, opposite to the nose, of the motor end cover is provide with the motor mounting hole, so that lubricating oil is prevented from splashing to the motor stator, and service life of the motor is ensured.
Description
Technical field
The utility model relates to a kind of Sewing machines, particularly a kind of Sewing machines being driven by motor straight.
Background technology
The Sewing machines of existing motor direct-drive comprises head and the motor being connected with head, and wherein head is provided with sewing mechanism, and sewing mechanism is provided with main shaft, and main shaft is connected with rotor and obtains driving force, thereby drives sewing mechanism work; Also comprise the head end cap being connected with head, head end cap is provided with motor installing hole towards the end face of head, in order to reduce cost, the stator of motor is arranged in head end cap installing hole, do not use independently motor housing, after head end cap is connected with head, whole motor is firmly connected with head.
The shortcoming of prior art is: motor straight junction is to head, does not cover centre, the lubricating oil that sewing mechanism in body is used under the running up of mechanism after easy heating viscosity decline and spatter to motor stator along main shaft, machine oil becomes easily infected by dust, make dust adhesion on stator, cause stator coil heat radiation bad, accelerate the aging of stator coil.
Utility model content
The utility model is in order to overcome defect in above-mentioned prior art, by motor installing hole being arranged on to the electric motor end cap end face of head dorsad, avoids lubricating oil to splash down on motor stator along main shaft, guarantees the working life of motor.
For achieving the above object, the utility model provides a kind of electric-machine directly-driven Sewing machines, comprise, and head, head end cap and handwheel, head is provided with sewing mechanism, and sewing mechanism is connected with motor by main shaft; The head end cap dorsad end face of head is provided with motor installing hole, and motor stator is arranged in motor installing hole and forms firm connection, and head end cap is firmly connected with head; Head end cap is also provided with the via hole of main shaft, and via hole is not more than motor installing hole, and main shaft is connected with rotor in via hole stretches into motor installing hole.
In technique scheme, rotor is directly socketed main shaft and is firmly connected with main shaft.
In technique scheme, motor stator also comprises the circuit board of drive motors, and circuit board is arranged at the inner end of motor installing hole, and circuit board is semicircle annular, and the face size of ring width and stator is suitable.
In technique scheme, handwheel is connected with end or the close end of head spindle.
In technique scheme, be provided with motor protecting cover between handwheel and motor, protecting cover is circular ring structure, suitable with the section configuration of motor stator, realizes the protection to motor stator.
Compared with prior art, the utility model, by motor installing hole being arranged on to the electric motor end cap end face of head dorsad, avoids lubricating oil to splash down on motor stator along main shaft, guarantees the working life of motor.
