Description

Cam swing mechanism of needle type winding machine

Technical Field

The invention belongs to the technical field of electrical mechanical equipment, and particularly relates to a reciprocating swinging mechanism for a winding head on a needle type machine.

Background

In the production and manufacturing process of the motor stator, the variable frequency motor stator needs to be wound between two grooves at a certain angle in a reciprocating manner. The existing winding mode is that a stator does angle reciprocating swing, and a winding head does not do angle reciprocating swing; this approach requires the use of large, dedicated motors, which is costly. And the private clothes motor is easy to heat and unstable, and cannot adapt to high-speed winding.

Disclosure of Invention

The invention aims to provide a mechanism which has simple structure and low processing cost and provides stable and accurate angle swing for a winding head, and the mechanism can replace the traditional angle swing mechanism which has high cost and poor swing stability and can not adapt to high-speed winding.

The technical scheme of the invention is as follows: a conjugate type double-cam swing mechanism: the cam 1 and the cam sleeve 2 form a conjugate cam assembly which is connected with a transmission main shaft of a winding machine through an expansion sleeve 3. The cam oscillating bar 4, the incomplete cam 7, the bearing 6 and the support shaft 5 form an oscillating bar component; the conjugate cam assembly rotates with the drive shaft. During the rotation of the cam, the cam curve profiles corresponding to the lift angle, the far repose angle, the return angle and the near repose angle of the cam 1 are used for realizing the reciprocating circular motion of the cam swing rod 4 with accurate angle, such as swinging, stillness, swinging and stillness. The cam oscillating bar 4 transmits the reciprocating circular motion to the gear 11 through the incomplete gear 7, and the gear 11 is transmitted to the winding needle rod again so as to realize the reciprocating circular swing of the winding needle rod at a certain angle. By adjusting the gear ratio of the incomplete gear 7 and the gear 1, the reciprocating swing of the needle rod with different angles can be obtained.

Has the advantages that: by adopting the technical scheme, the conjugate cam assembly and the swing rod assembly are fixed reliably, the processing is easy, and the precision can be ensured, so that the relative movement of the conjugate cam assembly and the swing rod assembly is accurate. Thereby furthest guarantee the accurate wire winding of wire winding head. And the noise is low and the service life is long. Especially, the stator yield can be improved under the condition of high-speed winding.

the technical solution of the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

FIG. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a cross-sectional view of fig. 1.

The specific implementation mode is as follows:

referring to fig. 1 and 2, a cam oscillating mechanism of a needle type winding machine. The cam 1 and the cam sleeve 2 form a conjugate cam assembly, and the two cams 1 are arranged on the cam sleeve 2 in a mirror image mode. The conjugate cam assembly is mounted on the winding support housing by means of ball bearings 9. The expansion sleeve 3 is used for connecting the cam component with the transmission main shaft of the winding machine. A roller bearing 6 is arranged between the inner hole of the cam oscillating bar 4 and the installation supporting shaft 5, and the incomplete gear 7, the bearing 6, the supporting shaft 5 and the cam oscillating bar 4 are connected to form an oscillating bar component. The cam swing rod component is fastened on the winding machine shell. The conjugate cam assembly rotates with the drive shaft. During the rotation of the cam, the accurate-angle swinging, static, swinging and static reciprocating circular motion of the swing rod is realized through cam curves corresponding to the lift angle, the far repose angle, the return angle and the near repose angle of the cam. The oscillating bar transmits the reciprocating circular motion to the gear 11 through the incomplete gear 7, and the gear 11 is transmitted to the winding needle rod again so as to realize the reciprocating circular oscillation of the winding needle rod at a certain angle. By adjusting the gear ratio of the incomplete gear 7 and the gear 11, the reciprocating swing of the needle rod with different angles can be obtained. The angle of the support shaft 5 can be adjusted to adjust the gap between the gears.
